Abstract
Background: Previous studies did not consider the importance of the first mealtime on metabolic health.
Objectives: Present study aimed to investigate the association between the first mealtime and obesity among a sample of female students in Isfahan.
Patients and Methods: This cross-sectional study was conducted on 265 female students, aged 11 to 13 years, in Isfahan, by using the systematic random sampling. Anthropometric variables were measured based on standard guidelines. Dietary intakes were evaluated by using validated food frequency questionnaire. Analyses were adjusted for potential confounders.
Results: There was no significant difference in the mean of age, height, physical activity, and blood pressure between those who consumed first meal before and after 9:30 A.M. The mean of BMI and waist circumference were significantly lower in participants who had earlier breakfast consumption than in those with later intake of the first meal (P < 0.05). After adjustment for energy, fat, saturated fat, dietary fiber, and physical activity, the prevalence of overweightness, obesity, and central adiposity was lower in those who consumed breakfast earlier (P < 0.05).
Conclusions: The prevalence of overweightness, obesity, and central adiposity was lower among earlier breakfast consumers. More investigations especially prospective studies should be conducted to clarify this association.
