Vitamin-D status among adolescent attending in the Out Patient Department of Selected Tertiary Hospitals in Bangladesh

Abstract

Context/Background: Lack of vitamin D is a global issue that has been linked to a number of health problems. In Bangladesh, it is quite prevalent in all age categories, but it is particularly prevalent in children and adolescents of both sexes. Since vitamin D is produced by cutaneous synthesis when exposed to plenty of sunlight, the incidence of vitamin D insufficiency in Bangladesh is often disregarded. The objective of the current study was to assess the vitamin D status of adolescents attending in the outpatient department (OPD) of selected tertiary hospitals in Bangladesh, as well as the relationship between vitamin D status and dietary habits and socio-demographic traits. Techniques/Methods Two chosen hospitals' outpatient departments recruited adolescents (10–19 years old) for a cross-sectional survey. The study employed convenience sampling of 384 adolescents who came to these hospitals and their medical reports were available at the hospital. Vitamin D status was evaluated based on the medical reports. Alongside, dietary habits were recorded using the Food Frequency Questionnaire (FFQ). A multinomial logistic regression model was built to determine the predictors of the participants' vitamin D status. Results: More than 58% of the respondents were younger adolescents (aged 10-14 years) and around two-thirds were girls. It was discovered that 36.7% of the adolescents had inadequate amounts of vitamin D, and 32% were vitamin D deficient. Deficiency level was significantly higher among older adolescents (15-19 years of age). Girls were significantly more deficient 36.2% than boys 24.6%. In addition to other socio-demographic factors, mothers with low- paying jobs, mothers whose education level was primary/below or no institutional education, families with lower incomes, etc., had higher prevalence of vitamin D deficiency. Regarding dietary habits, the study found that respondents who regularly consumed foods high in vitamin D i.e. beef, fatty fish, egg, dairy, fortified oils, nuts, fruits and vegetables, Horlicks had lower rate of vitamin D deficiency. A multinomial logistic regression analysis showed 7 that the occupation level of the mother (service holder), the less frequent consumption of beef, dairy, fortified oil, and Horlicks (a nutritional supplement drink) as significant predictors for vitamin D deficiency. Conclusion: The present study found a positive impact of consumption of certain vitamin D-rich food items (beef, dairy, fortified oil, and Horlicks) on vitamin D levels of adolescents. Adolescents who consumed these items frequently had a lower risk of vitamin D deficiency than those who did so occasionally or never. Therefore, if any awareness programs or campaigns could be conducted for both parents and adolescents, it might be beneficial for reducing vitamin D deficiency. Additionally, if it's feasible, more study can be done to fortify food with vitamin D through further research.
