Zusammenfassung

OBJECTIVE: To quantify the prevalence of obesity and obesity-related factors in a cross-sectional, observational study of Caribbean students using the results of three recent surveys of health behavior among undergraduates in Barbados, Grenada, and Jamaica. METHODS: A total of 1 578 Caribbean undergraduate students from Barbados, Grenada and Jamaica (ages 18–30 years) completed questionnaires and had physical measurements recorded. Multivariable logistic regression was used to estimate odds ratios (ORs) for the association of nutrition behaviors with prevalence of obesity (body mass index ≥ 30 kg/m(2)); elevated waist-to-height ratio (W/ht) (> 0.5); and high waist circumference (WC) (> 88 cm in females, > 102 cm in males). Models were adjusted for age, year in university, socioeconomic status, and sex. RESULTS: There was a higher prevalence of obesity (13% versus 10%), high WC (21% versus 7%), and high W/ht (35% versus 25%) in females relative to males. Compared to females, males had reduced odds of obesity (OR 0.46), high WC (OR 0.22), and high W/ht (OR 0.61) (P < 0.05 for all). Both females (46%) and males (24%) reported high levels of physical inactivity. Fruit and vegetable consumption was low (approximately two servings per day). Many students reported avoiding fatty foods (40%); this behavior was associated with high W/ht (OR 1.68), obesity (OR 1.90), and high WC (OR 1.82) (P < 0.05 for all). Irregular breakfast consumption, age, and year of study were also positively associated with obesity. Physical activity was not significantly associated with any obesity measure. CONCLUSIONS: There was a low prevalence of healthy behaviors and a high prevalence of obesity in this sample of Caribbean young adults.
