Epidemiology of dietary supplement use in Serbia: Report from Novi Sad

The primary objectives were to assess the prevalence of dietary supplement (DS) use and to identify specific demographic and lifestyle characteristics of DS users from Novi Sad, Serbia as well as the most commonly used DS and reasons for their use.

Observational, cross-sectional study.

Data on demographics, lifestyle and dietary supplement use of 435 adults from Novi Sad, Serbia were collected using an online questionnaire.

In total, 435 subjects completed the questionnaire (62.3% women). Prevalence of dietary supplement use in the sample was 42.8%. More women used DS than men (p = 0.002). Higher use of DS was reported among individuals 65+, while the young used DS less (p = 0.001), but the highest proportions of DS users was from the 45-54 age group. DS were used more among those with lower education levels (p < 0.001) and no income (p = 0.009). The highest percentages of DS users reported daily intakes of fruits and moderate physical activity, were non-smokers and social drinkers. Main reason for DS use was maintaining general health. The most commonly used DS were minerals and/or vitamins (68.8%).

We report a high prevalence of dietary supplement use in Novi Sad. DS use was associated with being a female, being older and having minimal/average income, the latter being opposite of the usual findings. Our results warrant a more detailed examination of the association between income, DS use and healthcare availability in developing countries such as Serbia.
