Dietary Habits of Sports Volunteers and Their Associations with Sociodemographic Characteristics: A Cross-Sectional Study

Background: Dietary behaviors are important modifiable factors related to health and well-being. Sports volunteers represent a population involved in sport-related environments, yet limited evidence is available regarding their specific dietary behaviors and their associations with sociodemographic characteristics. Materials and Methods: A cross-sectional survey was conducted among 297 sports volunteers (184 women, 113 men) at international sporting events in Poznan, Poland. Twenty specific dietary behaviors, including meal frequency, consumption of fruits, vegetables, cereal products, meat, dairy products, fish, sweets, sugar-sweetened beverages, salty snacks, ready-made meals, legumes, water, and selected eating behaviors, were assessed using a 20-item dietary habits questionnaire developed in accordance with dietary recommendations of the National Institute of Public Health and the National Center for Nutrition Education in Poland. Gender, age, educational attainment, and BMI were recorded. Chi-square tests were used to examine bivariate associations between each dietary behavior and sociodemographic characteristics. Multivariable logistic regression models were subsequently applied to dietary behaviors showing statistically significant bivariate associations. Results: Of the 20 dietary behaviors assessed, only a small number varied significantly according to sociodemographic characteristics. Women reported higher adherence to daily fruit consumption (46.8% vs. 28.1%; p = 0.002) and daily consumption of at least three portions of vegetables (44.1% vs. 28.9%; p = 0.013) than men. Participants aged 18 years differed from older age groups in daily fruit consumption and limiting meat consumption to no more than once per day (p < 0.05). Educational attainment was associated with daily fruit consumption, with participants with primary education reporting higher adherence than those with higher education (48.8% vs. 25.3%; p = 0.011). BMI was associated with several dietary behaviors, including fruit consumption, avoiding snacking between meals, and portion control (p < 0.05). In multivariable analyses, female gender remained independently associated with fruit and vegetable consumption, while younger age was independently associated with daily fruit consumption and lower meat consumption. BMI remained independently associated with daily fruit consumption, whereas educational attainment was no longer significantly associated with dietary behaviors after adjustment. Conclusions: Most of the 20 dietary behaviors assessed did not differ significantly according to the examined sociodemographic characteristics. The observed associations were limited to selected behaviors and varied by gender, age, educational attainment, and BMI. Further research should examine additional factors, including physical activity, volunteering characteristics, and socioeconomic conditions, that may contribute to dietary behaviors among sports volunteers.
