Contributing Sociodemographic and Socioeconomic Factors of Overweight and Obesity Among Libyan University Students

Objective: This study aimed to determine the prevalence of obesity and overweight among undergraduate students in Libyan public universities and examine the association between demographic and socioeconomic factors with obesity. Additionally, differences in eating habits and physical activity between male and female students were analyzed. Theoretical Framework: The study is based on public health and nutrition theories that explore the influence of socioeconomic status and lifestyle choices on obesity. Concepts related to dietary behaviors, physical activity, and health disparities provided the foundation for the investigation. Method: A cross-sectional study was conducted using probabilistic sampling to select 500 undergraduate students aged 18-24 years from public universities on the west coast of Libya. Anthropometric measurements, including weight and height, were collected using a digital scale and stadiometer. Socioeconomic and lifestyle data were gathered through structured questionnaires. Results and Discussion: The prevalence of obesity and overweight was higher among female students (29.6%) than male students (19.6%). Logistic regression analysis identified income and food expenditure as significant predictors of obesity. Notable differences were observed in eating habits and physical activity levels between males and females. The findings underscore the need for targeted interventions promoting healthier lifestyles among students. Research Implications: The study highlights the impact of socioeconomic factors on obesity, informing public health policies and university-based health programs to encourage better nutrition and increased physical activity. Originality/Value: This research contributes to the limited literature on student obesity in Libya, offering valuable insights for policymakers and educators to implement evidence-based strategies for obesity prevention.
