This study aimed to investigate the socio-demographic and lifestyle factors influencing the use of dietary supplements among university students in Warsaw. The results showed that 41% of participants were dietary supplement users, with factors such as gender, physical activity, BMI, chronic diseases, nutritional knowledge, special diet habits, meal frequency, and fortified food consumption being associated with supplement use. Additionally, adherence to a Mediterranean-style diet was positively correlated with dietary supplement usage.
The study aimed to examine socio-demographic and lifestyle determinants, including diet quality, of dietary supplement (DS) use among 2545 students who attended public universities in Warsaw. The data was collected using a self-administered health and lifestyle questionnaire and a 5-day dietary record method. Diet quality was assessed using a Mediterranean Diet Score. To determine the covariates of DS use, multivariate-adjusted logistic regression models with an estimation of odds ratios (ORs) and 95% confidence intervals (95% CIs) were used. The results showed that 41% of participants were DS users. The following predictors of DS use were identified: gender (male vs. female; OR:0.62, 95% CI:0.50-0.79), physical activity (high vs. low; OR:1.79, 95% CI:1.45-2.20), BMI (>= 25 vs. 18.5-24.9 kg/m(2); OR:0.77, 95% CI:0.61-0.98), cigarette smoking (yes vs. no; OR:0.67, 95% CI:0.52-0.86), and presence of chronic diseases (yes vs. no; OR:2.37, 95% CI:1.89-2.98). Moreover, higher nutritional knowledge, special diet usage, eating more meals/day, and fortified food consumption were determinants of DS use. Adherence to the Mediterranean-style diet was positively associated with DS use, a 1-score increment was associated with a 10% (p-trend = 0.011) higher probability of DS usage. Given that the use of vitamins and/or minerals is common among university students and their users are characterized by eating a higher quality diet, investigating the contribution of DS in overall dietary nutrient intake warrants further study.
