Effects of Food Supplementation and Psychosocial Stimulation on Growth and Development of Severely Malnourished Children: Intervention Studies in Bangladesh
2012 (English)Doctoral thesis, comprehensive summary (Other academic)
Early childhood malnutrition is a global public health problem with serious short- and long-term consequences. The aim of this thesis is to evaluate the effects of psychosocial stimulation (PS) with or without food supplementation (FS) on growth and development of severely malnourished children, quality of home environment, mother’s child-rearing practices and depressive symptoms. The study setting was Dhaka, Bangladesh, and the participants were severely malnourished children, aged 6-24 months, admitted at Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B). A hospital-based study was conducted in Nutrition Rehabilitation Unit of ICDDR,B hospital, where a control group (n=43) was studied initially, followed by an intervention group (n=54). All received standard nutrition rehabilitation care. The intervention group received daily group meetings and play sessions in the hospital, and was thereafter visited at home for 6 months. A community-based randomised trial was conducted including children (n=507) admitted at hospital for initial treatment of an acute infection, and thereafter assigned to PS, FS, PS+FS, clinic control or hospital control groups. PS was delivered at follow-up visits, fortnightly for 6 months at community clinics. FS included distribution of cereal-based food packets (150–300 kcal/day depending on age) for 3 months. All groups received standard medical care and micronutrient supplementation. In the hospital-based study, the intervention group had significantly higher scores in mental (p<0.001, effect size 0.52 SD) and motor development (p=0.047, effect size 0.37 SD), and weight (p=0.03, effect size 0.39 SD), after 6- months intervention. In the community-based trial, there was a significant effect of stimulation after six months of intervention on children’s mental development (group*session interaction p=0.037, effect size=0.37 SD) and weight (group*session interaction p=0.02, effect size=0.26 SD) but no effect on motor development or linear growth. The PS+FS and PS groups differed in total HOME score, two HOME subscales (maternal involvement and play materials), and in mother’s child- rearing practices scores but not in depressive symptoms. PS with or without FS had small improvement on children’s growth and development, quality of home environment and mother’s rearing-practices of severely malnourished children. More intensive interventions with longer duration are therefore recommended.
