Prevalence, correlates and common conditions associated with adolescent dietary supplement use

Objective: There is a broad spectrum of dietary supplements (DS) and their accessibility worldwide. However, little is known about the prevalence of DS use among Bangladeshi adolescents. This study estimates the prevalence, correlates and common conditions related to DS use. Design: A cross-sectional, convenient sampling strategy was adopted using an interviewer-administered, structured questionnaire. Setting: Kurigram and Patuakhali districts of Bangladesh. Participants: 702 adolescents aged 10–19 years. Results: The overall prevalence of DS use was 83 %. The majority of participants (93·4 %) agreed that DS were good for health, and 28·3 % reported general health and well-being as the reason for using DS. The most frequently used supplements were multivitamins (38·6 %) and Ca (37 %). DS use was more common among adolescents who had ≤5 siblings, good health status, no chronic diseases, a positive impression that DS are good for health and who had the tendency to encourage DS to others. DS use was also higher among those who received DS information from healthcare providers, professional literature, friends, family and relatives. Conclusions: The prevalence of DS use is relatively higher among Bangladeshi adolescents compared to Bangladeshi adults and adolescents from other countries, highlighting the inclination towards DS use. Guidelines for safe DS use for adolescents are warranted to control DS use and prevent adverse effects
