The relationship of fast food consumption with sociodemographic factors, body mass index and dietary habits among university students

ABSTRACT

Purpose University students are one of the vulnerable groups in terms of having nutritional problems due to their lifestyle and social environment. This study aims to determine the consumption of fast food among university students and evaluate factors that may impact it, such as sociodemographic factors, body mass index (BMI) or nutritional habits. Design/methodology/approach A cross-sectional study was conducted among a random sample of 184 university students (47.8% men and 52.2% women) with a mean age of 21.1 +/- 2.0 years. The survey included students' sociodemographic characteristics, anthropometric measurements, nutritional habits and fast-food consumption. Chi-square test, t-test and binary logistic regression analysis were used depending on the characteristics of the data. Findings Results indicated that 39.7% of the students consumed fast food at least once in 15 days and preferred these foods for taste, workload and social activity. Consumption of fast food occurred at an earlier age in men (%13.6) and the portions were higher than portions of vegetables (p = 0.001). By using regression analysis, a statistically significant relationship was found between the frequency of fast-food consumption and age, gender, economic status, BMI, the amount of vegetables consumed daily and the habit of eating breakfast (p < 0.05). Research limitations/implications It is planned to reach more students in the study. However, due to the COVID-19 pandemic, transportation to students became difficult or could not be reached. Originality/value This study is one of the rare studies examining students' orientation to fast food. The number of studies in this field in Turkey is limited.
