    Dietary vitamin D intake and risk of type 2 diabetes in the European Prospective Investigation into Cancer and Nutrition: the EPIC-InterAct study2014In: European Journal of Clinical Nutrition, ISSN 0954-3007, E-ISSN 1476-5640, Vol. 68, no 2, 196-202 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND/OBJECTIVES: Prospective cohort studies have indicated that serum vitamin D levels are inversely related to risk of type 2 diabetes. However, such studies cannot determine the source of vitamin D. Therefore, we examined the association of dietary vitamin D intake with incident type 2 diabetes within the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct study in a heterogeneous European population including eight countries with large geographical variation.

    SUBJECTS/METHODS: Using a case-cohort design, 11 245 incident cases of type 2 diabetes and a representative subcohort (N = 15 798) were included in the analyses. Hazard ratios (HR) and 95% confidence intervals (CIs) for type 2 diabetes were calculated using a Prentice-weighted Cox regression adjusted for potential confounders. Twenty-four-hour diet-recall data from a subsample (N = 2347) were used to calibrate habitual intake data derived from dietary questionnaires.

    RESULTS: Median follow-up time was 10.8 years. Dietary vitamin D intake was not significantly associated with the risk of type 2 diabetes. HR and 95% CIs for the highest compared to the lowest quintile of uncalibrated vitamin D intake was 1.09 (0.97-1.22) (P-trend = 0.17). No associations were observed in a sex-specific analysis. The overall pooled effect (HR (95% CI)) using the continuous calibrated variable was 1.00 (0.97-1.03) per increase of 1 mg/day dietary vitamin D.

    CONCLUSIONS: This observational study does not support an association between higher dietary vitamin D intake and type 2 diabetes incidence. This result has to be interpreted in light of the limited contribution of dietary vitamin D on the overall vitamin D status of a person.

    What is a healthy Nordic diet? Foods and nutrients in the NORDIET study2012In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 56, 18189Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: A healthy Nordic diet (ND), a diet based on foods originating from the Nordic countries, improves blood lipid profile and insulin sensitivity and lowers blood pressure and body weight in hypercholesterolemic subjects.

    OBJECTIVE: To describe and compare food and nutrient composition of the ND in relation to the intake of a Swedish reference population (SRP) and the recommended intake (RI) and average requirement (AR), as described by the Nordic nutrition recommendations (NNR).

    DESIGN: The analyses were based on an estimate of actual food and nutrient intake of 44 men and women (mean age 53±8 years, BMI 26±3), representing an intervention arm receiving ND for 6 weeks.

    RESULTS: The main difference between ND and SRP was the higher intake of plant foods, fish, egg and vegetable fat and a lower intake of meat products, dairy products, sweets and desserts and alcoholic beverages during ND (p<0.001 for all food groups). Intake of cereals and seeds was similar between ND and SRP (p>0.3). The relative intake of protein, fat and carbohydrates during ND was in accordance with RI. Intake of all vitamins and minerals was above AR, whereas sodium intake was below RI.

    CONCLUSIONS: When compared with the food intake of an SRP, ND is primarily a plant-based diet. ND represents a balanced food intake that meets the current RI and AR of NNR 2004 and has a dietary pattern that is associated with decreased morbidity and mortality.

    Role of a prudent breakfast in improving cardiometabolic risk factors in subjects with hypercholesterolemia: A randomized controlled trial2015In: Clinical Nutrition, ISSN 0261-5614, E-ISSN 1532-1983, Vol. 34, no 1, 20-26 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND & AIMS:

    It is unclear whether advising a prudent breakfast alone is sufficient to improve blood lipids and cardiometabolic risk factors in overweight hypercholesterolemic subjects. The aim of this study was to investigate whether a prudent low-fat breakfast (PB) rich in dietary fiber lowers low-density lipoprotein cholesterol (LDL-C) and other cardiometabolic risk factors in subjects with elevated LDL-cholesterol levels.

    METHODS:

    In a parallel, controlled, 12-week study, 79 healthy overweight subjects (all regular breakfast eaters) were randomly allocated to a group that received a PB based on Nordic foods provided ad libitum or a control group that consumed their usual breakfast. The primary outcome was plasma LDL-C. Secondary outcomes were other blood lipids, body weight, sagittal abdominal diameter (SAD), glucose tolerance, insulin sensitivity and inflammation markers (C-reactive protein [CRP] and tumor necrosis factor receptor-2 [TNF-R2]), and blood pressure. The PB was in accordance with national and Nordic nutrition recommendations and included oat bran porridge with low-fat milk or yogurt, bilberry or lingonberry jam, whole grain bread, low-fat spread, poultry or fatty fish, and fruit.

    RESULTS:

    No differences were found in LDL-C, other blood lipids, body weight, or glucose metabolism, but SAD, plasma CRP, and TNF-R2 decreased more during PB compared with controls (p < 0.05). In the overall diet, PB increased dietary fiber and β-glucan compared with controls (p < 0.05).

    CONCLUSIONS:

    Advising a prudent breakfast for 3 months did not influence blood lipids, body weight, or glucose metabolism but reduced markers of visceral fat and inflammation. The trial was registered in the Current Controlled Trials database (http://www.controlled-trials.com); International Standard Randomized Controlled Trial Number (ISRCTN): 84550872.

    The effects of storage time and sampling season on the stability of serum 25-hydroxy vitamin D and androstenedione2010In: Nutrition and Cancer, ISSN 0163-5581, E-ISSN 1532-7914, Vol. 62, no 1, 51-57 p.Article in journal (Refereed)
    Abstract [en]

    Knowledge of the stability of serum samples stored in large biobanks is pivotal for reliable assessment of hormone-dependent disease risks. We studied the effects of sample storage time and season of serum sampling on the stability of 25-hydroxy vitamin D (25-OHD) and androstenedione in a stratified random sample of 402 women, using paired sera from the Finnish Maternity Cohort. Serum samples selected were donated between 6 and 24 yr ago. The storage time did not affect serum 25-OHD and androstenedione levels. However, there was a significant mean difference in the 25-OHD levels of sera withdrawn during winter (first sample) vs. during summer (second sample; -18.4 nmol/l, P ≤ 0.001). Also at the individual level, there were significant differences in average 25-OHD levels between individuals with the paired sera taken at winter–winter compared with other alternatives (summer–winter, winter–summer, and summer–summer). The androstenedione levels showed no such differences. Long-term storage does not affect serum 25-OHD and androstenedione levels, but sampling season is an important determinant of 25-OHD levels. Stored serum samples can be used to study disease associations with both hormones. However, sampling season needs to be taken into account for 25-OHD by considering matching and stratification and, if possible, serial sampling.

    A method for sensitivity analysis to assess the effects of measurement error in multiple exposure variables using external validation data2016In: BMC Medical Research Methodology, ISSN 1471-2288, E-ISSN 1471-2288, Vol. 16, 139Article in journal (Refereed)
    Abstract [en]

    Background: Measurement error in self-reported dietary intakes is known to bias the association between dietary intake and a health outcome of interest such as risk of a disease. The association can be distorted further by mismeasured confounders, leading to invalid results and conclusions. It is, however, difficult to adjust for the bias in the association when there is no internal validation data. Methods: We proposed a method to adjust for the bias in the diet-disease association (hereafter, association), due to measurement error in dietary intake and a mismeasured confounder, when there is no internal validation data. The method combines prior information on the validity of the self-report instrument with the observed data to adjust for the bias in the association. We compared the proposed method with the method that ignores the confounder effect, and with the method that ignores measurement errors completely. We assessed the sensitivity of the estimates to various magnitudes of measurement error, error correlations and uncertainty in the literature-reported validation data. We applied the methods to fruits and vegetables (FV) intakes, cigarette smoking (confounder) and all-cause mortality data from the European Prospective Investigation into Cancer and Nutrition study. Results: Using the proposed method resulted in about four times increase in the strength of association between FV intake and mortality. For weakly correlated errors, measurement error in the confounder minimally affected the hazard ratio estimate for FV intake. The effect was more pronounced for strong error correlations. Conclusions: The proposed method permits sensitivity analysis on measurement error structures and accounts for uncertainties in the reported validity coefficients. The method is useful in assessing the direction and quantifying the magnitude of bias in the association due to measurement errors in the confounders.

    Engagement in New Dietary Habits: Obese Women's Experiences from Participating in a 2-Year Diet Intervention2016In: International Journal of Behavioral Medicine, ISSN 1070-5503, E-ISSN 1532-7558, Vol. 23, no 1, 84-93 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Dietary weight loss interventions most often result in weight loss, but weight maintenance on a long-term basis is the main problem in obesity treatment. There is a need for an increased understanding of the behaviour patterns involved in adopting a new dietary behavior and to maintain the behaviour over time.

    PURPOSE: The purpose of this paper is to explore overweight and obese middle-aged women's experiences of the dietary change processes when participating in a 2-year-long diet intervention.

    METHODS: Qualitative semi-structured interviews with 12 overweight and obese women (54-71 years) were made after their participation in a diet intervention programme. The programme was designed as a RCT study comparing a diet according to the Nordic nutrition recommendations (NNR diet) and a Palaeolithic diet (PD). Interviews were analysed according to Grounded Theory principles.

    RESULTS: A core category "Engagement phases in the process of a diet intervention" concluded the analysis. Four categories included the informants' experiences during different stages of the process of dietary change: "Honeymoon phase", "Everyday life phase", "It's up to you phase" and "Crossroads phase". The early part of the intervention period was called "Honeymoon phase" and was characterised by positive experiences, including perceived weight loss and extensive support. The next phases, the "Everyday life phase" and "It's up to you phase", contained the largest obstacles to change. The home environment appeared as a crucial factor, which could be decisive for maintenance of the new dietary habits or relapse into old habits in the last phase called "Crossroads phase".

    CONCLUSION: We identified various phases of engagement in the process of a long-term dietary intervention among middle-aged women. A clear personal goal and support from family and friends seem to be of major importance for long-term maintenance of new dietary habits. Gender relations within the household must be considered as a possible obstacle for women engaging in diet intervention.

    Den hälsosamma kosten: uppfattningar, resonemang och livsmedelsval2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Most consumers today are very health conscious and wish to eat a healthy diet, but they are faced with several problems in their everyday lives. Food and product choices can be about taking a stance and showing your identity, whether that is as a price conscious or environmentally conscious customer. As such many factors are in play when the consumer decides what a healthy diet is. The choice of diet and food thus becomes a complex everyday challenge. This is influenced by the debate around food and health in what is termed the mass media. The purpose of the study was to show how a sample of Swedish consumers percieve a healthy diet, the relation of said perception to comming nutrition reccommendations and the consumers’ views of diet and health. The study used semi-structured interviews as well as a web-based food frequency questionnaire with fourhundred respondents. Interviews centered on concepts of healthy diet and unhealthy diet, as well as the meaning of words frequently used in the debate around diet and health in mass media. The consumer’s view of a healthy diet mainly coincides with Swedish Nutritional Recommendations from 2004 and the proposal for Nordic Nutrition Recommendations from June, 2012. There are differences in the opinions of male and female subjects between self-estimated food consumption, the view of what a healthy diet should look like and on how often the defined food items should be consumed. A higher frequency of consumption of food items that the proposal for the Nordic Nutrition Recommendations have recommended be reduced, such as sausages, snacks and sweets was more acceptable to men than to women. Women’s perception of a healthy diet included a higher frequency of consumption of food items that the proposal for the Nordic Nutrition Recommendations have recommended be increased, such as fruits, berries and vegetables. Over all, the subjects were well informed and knowledgeable about what constitutes a healthy diet.

    Established BMI-associated genetic variants and their prospective associations with BMI and other cardiometabolic traits: the GLACIER Study2016In: International Journal of Obesity, ISSN 0307-0565, E-ISSN 1476-5497, Vol. 40, no 9, 1346-1352 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Recent cross-sectional genome-wide scans have reported associations of 97 independent loci with body mass index (BMI). In 3541 middle-aged adult participants from the GLACIER Study, we tested whether these loci are associated with 10-year changes in BMI and other cardiometabolic traits (fasting and 2-h glucose, triglycerides, total cholesterol, and systolic and diastolic blood pressures).

    METHODS: A BMI-specific genetic risk score (GRS) was calculated by summing the BMI-associated effect alleles at each locus. Trait-specific cardiometabolic GRSs comprised only the loci that show nominal association (P⩽0.10) with the respective trait in the original cross-sectional study. In longitudinal genetic association analyses, the second visit trait measure (assessed ~10 years after baseline) was used as the dependent variable and the models were adjusted for the baseline measure of the outcome trait, age, age(2), fasting time (for glucose and lipid traits), sex, follow-up time and population substructure.

    RESULTS: The BMI-specific GRS was associated with increased BMI at follow-up (β=0.014 kg m(-2) per allele per 10-year follow-up, s.e.=0.006, P=0.019) as were three loci (PARK2 rs13191362, P=0.005; C6orf106 rs205262, P=0.043; and C9orf93 rs4740619, P=0.01). Although not withstanding Bonferroni correction, a handful of single-nucleotide polymorphisms was nominally associated with changes in blood pressure, glucose and lipid levels.

    CONCLUSIONS: Collectively, established BMI-associated loci convey modest but statistically significant time-dependent associations with long-term changes in BMI, suggesting a role for effect modification by factors that change with time in this population.

    We are family - parents, siblings, and eating disorders in a prospective total-population study of 250,000 Swedish males and females2013In: International Journal of Eating Disorders, ISSN 0276-3478, E-ISSN 1098-108X, Vol. 46, no 7, 693-700 p.Article in journal (Refereed)
    Abstract [en]

    Objective: We examined how parental characteristics and other aspects of family background were associated with the development of eating disorders (ED) in males and females.

    Method: We used register data and record linkage to create the prospective, total-population study the Stockholm Youth Cohort. This cohort comprises all children and adolescents who were ever residents in Stockholm County between 2001 and 2007, plus their parents and siblings. Individuals born between 1984 and 1995 (N = 249, 884) were followed up for ED from age 12 to end of 2007. We used Cox regression modeling to investigate how ED incidence was associated with family socioeconomic position, parental age, and family composition.

    Results: In total, 3,251 cases of ED (2,971 females; 280 males) were recorded. Higher parental education independently predicted a higher rate of ED in females [e.g., adjusted hazard ratio (HR) 1.69 (95% CI: 1.42, 2.02) for degree-level vs. elementary-level maternal education], but not in males [HR 0.73 (95% CI: 0.42, 1.28), p < 0.001 for gender interaction]. In females, an increasing number of full-siblings was associated with lower rate of ED [e.g., fully adjusted HR 0.92 (95% CI: 0.88, 0.97) per sibling], whereas an increasing number of half-siblings was associated with a higher rate [HR 1.05 (95% CI: 1.01, 1.09) per sibling].

    Discussion: The effect of parental education on ED rate varies between males and females, whereas the effect of number of siblings varies according to whether they are full or half-siblings. A deeper understanding of these associations and their underlying mechanisms may provide etiological insights and inform the design of preventive interventions

    »Många studier genom åren har visat att inte ens en så enkel och lätt bestämd variabel som kroppsvikt registreras och analyseras tydligt över tid.«

    Man försöker trycka in kvalitet i klinisk nutrition i ett vårdsystem som inte är förberett på saken. Detta i en situation med a) brist på infrastruktur i vården, b) brist på utbildning/träning i klinisk nutrition hos personalen och c) avsaknad av en medicinsk specialitet för klinisk nutrition. Det skriver professor Gunnar Akner i en debatterande översiktsartikel.

    The association of coffee intake with liver cancer risk is mediated by biomarkers of inflammation and hepatocellular injury: data from the European Prospective Investigation into Cancer and Nutrition2015In: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 102, no 6, 1498-1508 p.Article in journal (Refereed)
    Abstract [en]

    Background: Higher coffee intake has been purportedly related to a lower risk of liver cancer. However, it remains unclear whether this association may be accounted for by specific biological mechanisms. Objective: We aimed to evaluate the potential mediating roles of inflammatory, metabolic, liver injury, and iron metabolism biomarkers on the association between coffee intake and the primary form of liver cancer-hepatocellular carcinoma (HCC). Design: We conducted a prospective nested case-control study within the European Prospective Investigation into Cancer and Nutrition among 125 incident HCC cases matched to 250 controls using an incidence-density sampling procedure. The association of coffee intake with HCC risk was evaluated by using multivariable-adjusted conditional logistic regression that accounted for smoking, alcohol consumption, hepatitis infection, and other established liver cancer risk factors. The mediating effects of 21 biomarkers were evaluated on the basis of percentage changes and associated 95% CIs in the estimated regression coefficients of models with and without adjustment for biomarkers individually and in combination. Results: The multivariable-adjusted RR of having >= 4 cups (600mL) coffee/d compared with <2 cups (300 mL)/d was 0.25 (95% CI: 0.11, 0.62; P-trend = 0.006). A statistically significant attenuation of the association between coffee intake and HCC risk and thereby suspected mediation was confirmed for the inflammatory biomarker IL-6 and for the biomarkers of hepatocellular injury glutamate dehydrogenase, alanine aminotransferase, aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), and total bilirubin, which-in combination-attenuated the regression coefficients by 72% (95% CI: 7%, 239%). Of the investigated biomarkers, IL-6, AST, and GGT produced the highest change in the regression coefficients: 40%, 56%, and 60%, respectively. Conclusion: These data suggest that the inverse association of coffee intake with HCC risk was partly accounted for by biomarkers of inflammation and hepatocellular injury.

    Adiposity, mediating biomarkers and risk of colon cancer in the European prospective investigation into cancer and nutrition study2014In: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 134, no 3, 612-621 p.Article in journal (Refereed)
    Abstract [en]

    Adiposity is a risk factor for colon cancer, but underlying mechanisms are not well understood. We evaluated the extent to which 11 biomarkers with inflammatory and metabolic actions mediate the association of adiposity measures, waist circumference (WC) and body mass index (BMI), with colon cancer in men and women. We analyzed data from a prospective nested case-control study among 662 incident colon cancer cases matched within risk sets to 662 controls. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression. The percent effect change and corresponding CIs were estimated after adjusting for biomarkers shown to be associated with colon cancer risk. After multivariable adjustment, WC was associated with colon cancer risk in men (top vs. bottom tertile RR 1.68, 95% CI 1.06-2.65; ptrend  = 0.02) and in women (RR 1.67, 95% CI 1.09-2.56; ptrend  = 0.03). BMI was associated with risk only in men. The association of WC with colon cancer was accounted mostly for by three biomarkers, high-density lipoprotein cholesterol, non-high-molecular-weight adiponectin and soluble leptin receptor, which in combination explained 46% (95% CI 37-57%) of the association in men and 50% (95% CI 40-65%) of the association in women. Similar results were observed for the associations with BMI in men. These data suggest that alterations in levels of these metabolic biomarkers may represent a primary mechanism of action in the relation of adiposity with colon cancer. Further studies are warranted to determine whether altering their concentrations may reduce colon cancer risk.

    Felnärd i välfärd: en studie om kostrådgivningens historia, utveckling och dess bakomliggande aktörer2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte och frågeställning

    Studiens syfte är att studera kostråd genom att empiriskt följa en och samma litteraturkälla; Vår Föda, från utgivningsstart 1949 och fram till 2005.

    Frågeställningarna är:

    • Finns det skillnader i kostråden under tidsperioden?
    • Vilken målgrupp vänder sig texterna främst till?

    Metod

    Tidskriften Vår Föda tar upp frågor främst kring matsäkerhet och kostvanor och presenterar artiklar skrivna främst av myndigheten Livsmedelsverkets experter inom olika områden. Genom en textanalys innefattande alla årgångar från 1949 till och med 2005 av denna tidskrift, har ett antal artiklar som tar upp kost och dess betydelse för en god hälsa legat till grund för hela studien. Valet av denna tidskrift grundar sig i dess unika kontinuitet över tid och valet av artiklar har gjorts efter en genomgång av artiklar, utifrån deras rubriker kring kost och hälsa.

    Resultat

    Studien gör gällande att kostråden under perioden är relativt konstanta, med fokus på blandad kost med begränsat fett- och sockerintag. Målgruppen är främst institutioner med yrkesverksamma personer inom kostområdet, skolor samt främst under senare år även privatpersoner som intresserar sig för kostfrågor.

    Slutsats

    De rekommendationer som ges kring kost i Vår Föda under de 56 åren som studien sträcker sig över har förändrats i ganska liten mån. Artiklarna är på senare tid skrivna för att kunna läsas av fler intressenter än enbart fackfolk inom kost och näringslära. Slutsatsen blir således att skillnaderna i rekommendationerna är små.

    Polyamines: total daily intake in adolescents compared to the intake estimated from the Swedish Nutrition Recommendations Objectified (SNO)2011In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 55, 5455- p.Article in journal (Refereed)
    Abstract [en]

    Background: Dietary polyamines have been shown to give a significant contribution to the body pool of polyamines. Knowing the levels of polyamines (putrescine, spermidine, and spermine) in different foods and the contribution of daily food choice to polyamine intake is of interest, due to the association of these bioactive amines to health and disease. Objective: To estimate polyamine intake and food contribution to this intake in adolescents compared to a diet fulfilling the Swedish Nutrition Recommendations. Design: A cross-sectional study of dietary intake in adolescents and an 'ideal diet' (Swedish nutrition recommendations objectified [SNO]) list of foods was used to compute polyamine intake using a database of polyamine contents of foods. For polyamine intake estimation, 7-day weighed food records collected from 93 adolescents were entered into dietetic software (Dietist XP) including data on polyamine contents of foods. The content of polyamines in foods recommended according to SNO was entered in the same way. Results: The adolescents' mean daily polyamine intake was 316 +/- 170 mu mol/day, while the calculated contribution according to SNO was considerably higher with an average polyamine intake of 541 mu mol/day. In both adolescent's intake and SNO, fruits contributed to almost half of the total polyamine intake. The reason why the intake among the adolescents was lower than the one calculated from SNO was mainly due to the low vegetable consumption in the adolescents group. Conclusions: The average daily total polyamine intake was similar to that previously reported in Europe. With an 'ideal' diet according to Swedish nutrition recommendations, the intake of this bioactive non-nutrient would be higher than that reported by our adolescents and also higher than that previously reported from Europe.

    Polyamines in foods: development of a food database2011In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 55, 5572- p.Article in journal (Refereed)
    Abstract [en]

    Background: Knowing the levels of polyamines (putrescine, spermidine, and spermine) in different foods is of interest due to the association of these bioactive nutrients to health and diseases. There is a lack of relevant information on their contents in foods. Objective: To develop a food polyamine database from published data by which polyamine intake and food contribution to this intake can be estimated, and to determine the levels of polyamines in Swedish dairy products. Design: Extensive literature search and laboratory analysis of selected Swedish dairy products. Polyamine contents in foods were collected using an extensive literature search of databases. Polyamines in different types of Swedish dairy products (milk with different fat percentages, yogurt, cheeses, and sour milk) were determined using high performance liquid chromatography (HPLC) equipped with a UV detector. Results: Fruits and cheese were the highest sources of putrescine, while vegetables and meat products were found to be rich in spermidine and spermine, respectively. The content of polyamines in cheese varied considerably between studies. In analyzed Swedish dairy products, matured cheese had the highest total polyamine contents with values of 52.3, 1.2, and 2.6 mg/kg for putrescine, spermidine, and spermine, respectively. Low fat milk had higher putrescine and spermidine, 1.2 and 1.0 mg/kg, respectively, than the other types of milk. Conclusions: The database aids other researchers in their quest for information regarding polyamine intake from foods. Connecting the polyamine contents in food with the Swedish Food Database allows for estimation of polyamine contents per portion.

    Association of the European lactase persistence variant (LCT-13910 C > T Polymorphism) with obesity in the Canary Islands2012In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 7, no 8, e43978Article in journal (Refereed)
    Abstract [en]

    Background: European lactose tolerance genotype (LCT -13910 C>T, rs4988234) has been positively associated to body mass indexes (BMI) in a meta-analysis of 31,720 individuals of northern and central European descent. A strong association of lactase persistence (LP) with BMI and obesity has also been traced in a Spanish Mediterranean population. The aim of this study was to analyze a potential association of LP compared to lactase non-persistence (LNP) with BMI in inhabitants of the Canary Islands of Spain using Mendelian randomization.

    Methods: A representative, randomly sampled population of adults belonging to the Canary Islands Nutrition Survey (ENCA) in Spain, aged 18-75 years (n = 551), was genotyped for the LCT - 13910 C>T polymorphism. Milk consumption was assessed by a validated questionnaire. Anthropometric variables were directly measured. WHO classification of BMI was used.

    Results: LP individuals were significantly more obese than LNP subjects (chi(2) = 10.59; p < 0.005). LP showed in a multivariate linear regression analysis showed a positive association of LP with BMI compared to LNP, (beta = 0.96; 95% CI: 0.08-1.85, p = 0.033). In a multinomial logistic regression analysis normal range weight LP subjects showed an odds ratio for obesity of 2.41; 95% CI 1.39-418, (p = 0.002) compared to LNP.

    Conclusions: The T-13910 of the allele LCT-13910 C>T polymorphism is positively associated with BMI. LP increases significantly the risk to develop obesity in the studied population. The LCT-13910 C>T polymorphism stands proxy for the lifetime exposure pattern, milk intake, that may increase susceptibility to obesity and to obesity related pathologies.

    AIim of the study: The aim was to determine if milk intake and MS are associated. We applied Mendelian randomization (MR). The SNP, LCT -13910 C>T, with the genotypes LP (TT/CT) and LNP (CC), was taken as a proxy for milk consumption.

    Methods: A representative sample of adults belonging to the Canary Islands Nutrition Survey (ENCA) in Spain aged 18-75 years (n = 551) was genotyped for the LCT -13910 C>T polymorphism. We used the International Diabetes Federation (IDF) criteria to define MS. RESULTS: 60% of the population was LP and 40% LNP. One hundred seven LP subjects (35.0%) and 53 LNP subjects (25.6%) showed MS (chi (2) = 5.04, p = 0.025). LP subjects showed a significantly higher odds ratio (OR) for MS than LNP subjects computed for the whole population: both the crude OR (1.56; 95% CI 1.06-2.31) and adjusted OR for sex, age, daily energy intake, physical activity and educational level (1.57; 95% CI 1.02-2.43). Adjusted OR for women with LP was 1.93; 95% CI 1.06-3.52.

    Conclusions: The T allele of the SNP might constitute a nutrigenetic factor increasing the susceptibility of LP subjects, especially women, to develop MS in the Canary Islands.

    Lactase persistence and milk consumption are associated with body height in Swedish preadolescents and adolescents2011In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 55, 7253Article in journal (Refereed)
    Abstract [en]

    Background: Body height is a classic polygenic trait. About 80%-90% of height is inherited and 10%-20% owed to environmental factors, of which the most important ones are nutrition and diseases in preadolescents and adolescents.

    Objective: The aim of this study was to explore potential relations between the LCT (lactase) C > T-13910 polymorphism, milk consumption, and body height in a sample of Swedish preadolescents and adolescents.

    Design: In a cross-sectional study, using a random sample of preadolescents and adolescents (n = 597), dietary intakes were determined. Anthropometric measurements including sexual maturity (Tanner stage) and birth weight were assessed. Parental body height and socio-economic status (SES) were obtained by questionnaires. Genotyping for the LCT C > T-13910 polymorphism that renders individuals lactase persistent (LP) or lactase non-persistent (LNP) was performed by DNA sequencing. Stepwise backward multivariate linear regression was used.

    Results: Milk consumption was significantly and positively associated with body height (beta =0.45; 95% CI: 0.040, 0.87, p =0.032). Adjustments were performed for sex, parental height, birth weight, body mass index (BMI), SES, and Tanner stage. This model explains 90% of the observed variance of body height (adjusted R-2 =0.89). The presence of the -13910 T allele was positively associated with body height (beta = 2.05; 95% CI: 0.18, 3.92, p =0.032).

    Conclusions: Milk consumption is positively associated with body height in preadolescents and adolescents. We show for the first time that a nutrigenetic variant might be able to explain in part phenotypic variation of body height in preadolescents and adolescents. Due to the small sample size further studies are needed.

    Body fat and dairy product intake in lactase persistent and non-persistent children and adolescents2010In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 54, no 5141Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Lactase non-persistent (LNP) individuals may be lactose intolerant and therefore on a more restricted diet concerning milk and milk products compared to lactase persistent (LP) individuals. This may have an impact on body fat mass.

    OBJECTIVE: This study examines if LP and LNP children and adolescents, defined by genotyping for the LCT-13910 C > T polymorphism, differ from each other with regard to milk and milk product intake, and measures of body fat mass.

    DESIGN: Children (n=298, mean age 9.6 years) and adolescents (n=386, mean age 15.6 years), belonging to the Swedish part of the European Youth Heart Study, were genotyped for the LCT-13910 C > T polymorphism. Dietary intakes of reduced and full-fat dairy varieties were determined.

    RESULTS: LNP (CC genotype) subjects consumed less milk, soured milk and yoghurt compared to LP (CT/TT genotype) subjects (p<0.001). Subsequent partitioning for age group attenuated this observation (p=0.002 for children and p=0.023 in adolescents). Six subjects were reported by parents to be 'lactose intolerant', none of whom were LNP. LNP children and adolescents consumed significantly less reduced fat milk and milk products than LP children and adolescents (p=0.009 for children and p=0.001 for adolescents).

    CONCLUSIONS: We conclude that LP is linked to an overall higher milk and dairy intake, but is not linked to higher body fat mass in children and adolescents.

    Lactase non-persistence as a determinant of milk avoidance and calcium intake in children and adolescents2013In: Journal of nutritional science, ISSN 2048-6790, Vol. 2, no e26, 1-5 p.Article in journal (Refereed)
    Abstract [en]

    This study examines if lactase non-persistent (LNP) children and adolescents differ from those who are lactase persistent (LP) as regards milk avoidance and Ca intake. We also studied potential differences in anthropometric features related to obesity, and examined if milk avoidance is associated with lactasepersistence status. Additionally, we aimed to determine if heterozygous subjects showed an intermediary phenotype as regards Ca intake. Furthermore, we tested if LP and LNP influence vitamin D intake. The European Youth Heart Study is an ongoing international, multi-centre cohort study primarily designed to address CVD risk factors. Children (n 298, mean age 9·6 years) and adolescents (n 386, mean age 15·6 years) belonging to the Swedish part of the European Youth Heart Study were genotyped for the LCT-13910 C > T polymorphism. Mendelian randomisation was used. Milk avoidance was significantly more common in LNP adolescents (OR 3·2; 95% CI 1·5, 7·3). LP subjects had higher milk consumption (P < 0·001). Accordingly, energy consumption derived from milk and Ca intake was lower in LNP (P < 0·05 and P < 0·001, respectively). Heterozygous subjects did not show an intermediary phenotype concerning milk consumption. LP or LNP status did not affect vitamin D intake or anthropometric variables. LNP in children and adolescents is associated with reduced intake of milk and some milk-product-related nutritional components, in particular Ca. This reduced intake did not affect the studied anthropometric variables, indicators of body fat or estimated vitamin D intake. However, independently of genotype, age and sex, daily vitamin D intake was below the recommended intakes. Milk avoidance among adolescents but not children was associated with LNP.

    Serum Fatty Acids, Desaturase Activities and Abdominal Obesity - A Population-Based Study of 60-Year Old Men and Women2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 1, e0170684Article in journal (Refereed)
    Abstract [en]

    Abdominal obesity is a key contributor of metabolic disease. Recent trials suggest that dietary fat quality affects abdominal fat content, where palmitic acid and linoleic acid influence abdominal obesity differently, while effects of n-3 polyunsaturated fatty acids are less studied. Also, fatty acid desaturation may be altered in abdominal obesity. We aimed to investigate cross-sectional associations of serum fatty acids and desaturases with abdominal obesity prevalence in a population-based cohort study. Serum cholesteryl ester fatty acids composition was measured by gas chromatography in 60-year old men (n = 1883) and women (n = 2015). Cross-sectional associations of fatty acids with abdominal obesity prevalence and anthropometric measures (e.g., sagittal abdominal diameter) were evaluated in multivariable-adjusted logistic and linear regression models, respectively. Similar models were employed to investigate relations between desaturase activities (estimated by fatty acid ratios) and abdominal obesity. In logistic regression analyses, palmitic acid, stearoyl-CoA- desaturase and Delta 6-desaturase indices were associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals) for highest versus lowest quartiles were 1.45 (1.19-1.76), 4.06 (3.27-5.05), and 3.07 (2.51-3.75), respectively. Linoleic acid, alpha-linolenic acid, docohexaenoic acid, and Delta 5-desaturase were inversely associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals): 0.39 (0.32-0.48), 0.74 (0.61-0.89), 0.76 (0.62-0.93), and 0.40 (0.33-0.49), respectively. Eicosapentaenoic acid was not associated with abdominal obesity. Similar results were obtained from linear regression models evaluating associations with different anthropometric measures. Sex-specific and linear associations were mainly observed for n3-polyunsaturated fatty acids, while associations of the other exposures were generally non-linear and similar across sexes. In accordance with findings from short-term trials, abdominal obesity was more common among individuals with relatively high proportions of palmitic acid, whilst the contrary was true for linoleic acid. Further trials should examine the potential role of linoleic acid and its main dietary source, vegetable oils, in abdominal obesity prevention.

    Variations in folate pathway genes are associated with unexplained female infertility2010In: Fertility and Sterility, ISSN 0015-0282, Vol. 94, no 1, 130-137 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate associations between folate-metabolizing gene variations, folate status, and unexplained female infertility. Design: An association study. Setting: Hospital-based IVF unit and university-affiliated reproductive research laboratories. Patient(s): Seventy-one female patients with unexplained infertility. Intervention(s): Blood samples for polymorphism genotyping and homocysteine, vitamin B12, and folate measurements. Main Outcome Measure(s): Allele and genotype frequencies of the following polymorphisms: 5,10-methylenetetra-hydrofolate reductase (MTHFR) 677C/T, 1298A/C, and 1793G/A, folate receptor 1 (FOLR1) 1314G/A, 1816delC, 1841G/A, and 1928C/T, transcobalamin II (TCN2) 776C/G, cystathionase (CTH) 1208G/T and solute carrier family 19, member 1 (SLC19A1) 80G/A, and concentrations of plasma homocysteine, vitamin B12, and serum folate. Result(s): MTHFR genotypes 677CT and 1793GA, as well as 1793 allele A were significantly more frequent among controls than in patients. The common MTHFR wild-type haplotype (677, 1298, 1793) CAG was less prevalent, whereas the rare haplotype CCA was more frequent in the general population than among infertility patients. The frequency of SLC19A1 80G/A genotypes differed significantly between controls and patients and the A allele was more common in the general population than in infertile women. Plasma homocysteine concentrations were influenced by CTH 1208G/T polymorphism among infertile women. Conclusion(s): Polymorphisms in folate pathway genes could be one reason for fertility complications in some women with unexplained infertility. (Fertil Steril (R) 2010;94:130-7.
