Sociodemographic differences in the use of dietary supplements in a representative sample of adults in Poland—a secondary analysis
Abstract
Introduction Dietary supplements are concentrated sources of vitamins, minerals, or other substances with nutritional or physiological effects. This study aimed to assess sociodemographic differences in the use of dietary supplements in a representative sample of adults in Poland. Methods This is a secondary analysis of a dataset generated during the representative cross-sectional survey (December 2024) carried out among 5,006 adults aged 18–64 years in Poland. Attitudes towards the use of dietary supplements were assessed. Results Among all respondents (n = 5,006), 39.1% reported regular use of dietary supplements in the 3 months preceding the present study, and another 31.5% reported occasional use. Among those who used supplements in the 3 months preceding the study, 11.4% had all of their supplements prescribed by a doctor, and another 22.7% had some of them. The highest prevalence of dietary supplement use was among those following a low-carbohydrate diet (58.4% regular and 27.9% occasional use), and the lowest among those who reported not paying much attention to their diet (24.9% regular and 32.2% occasional use). In multivariable logistic regression, female gender, younger age, secondary educational level, place of residence (living in cites = 500,000 residents), having at least 3 infections per year, lack of significant interest in own diet, and diet with restrictions on carbohydrate intake were significantly associated (p < 0.05) with higher odd of the regular use…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 5,006 participants or records.
