Caffeine Consumption and Sleep Habits Among Adults : A Quantitative Study (English)
Abstract [en]

ABSTRACT Background: Almost half of Sweden's adult population reports sleep problems and the trend is pointing upwards. Sleep is a basic human need. The recommendation is 7–9 hours of adequate sleep per night to reduce the risk of contracting various public health diseases. Caffeine is used worldwide as a stimulant, and consumption has changed after the advent of energy drinks. Aim: To investigate the consumption of caffeinated beverages and sleep habits among adults and investigate possible associations between them. Method: To answer the purpose of the study, a quantitative survey was conducted with a cross-sectional design in which 100 working adults participated. Both descriptive and comparative analyses were performed. Results: The total daily caffeine consumption in this study population consisted primarily of coffee, averaging 2.31 units per day, followed by energy drink with 0.40 units per day, and then tea, averaging 0.37 units per day. Men consumed the most devices per day, while women rated their sleep quality as the highest. However, no significant associations were found between high caffeine consumption and hours of sleep or sleep quality. Conclusions: In this study, no association was found between caffeine intake and sleep habits. However, possible associations should be investigated further in a larger population study as caffeine intake increases, especially among the young population.

SAMMANFATTNING Bakgrund: Nästan hälften av Sveriges vuxna befolkning rapporterar sömnproblem och trenden pekar uppåt. Sömn är ett grundläggande mänskligt behov. Rekommendationen är 79 timmars tillfredsställande sömn per natt för att minska risken för att drabbas av olika folkhälsosjukdomar. Koffein används världen över som stimulerande medel och konsumtionen har förändrats efter energidryckens intåg, Dryckerna har ofta höga doser koffein och rusar i försäljning. Syfte: Att undersöka konsumtion av koffeinhaltiga drycker och sömnvanor bland vuxna samt undersöka möjliga samband mellan dem. Metod: För att svara på syftet med studien genomfördes en kvantitativ undersökning med tvärsnittsdesign där 100 arbetande vuxna deltog. Både deskriptiva och jämförande analyser utfördes. Resultat: Den totala dagliga koffeinkonsumtionen i denna studiepopulation bestod främst av kaffe, i genomsnitt 2,31 enheter per dag, följt av energidryck med 0,40 enheter per dag och sedan te, i genomsnitt 0,37 enheter per dag. Män konsumerade flest enheter per dag, medan kvinnor bedömde sin sömnkvalitet som högst. Dock hittades inga signifikanta samband mellan hög koffeinkonsumtion och sömntimmar eller sömnkvalitet. Slutsatser: I denna studie framkom inga samband mellan koffeinintag och sömnvanor. Eventuella samband bör dock undersökas vidare i en större befolkningsstudie då koffeinintaget ökar, särskilt bland den unga befolkningen.
