Hassan BK, et al. - In this prospective cohort study, researchers assessed the link between breakfast and family breakfast frequency and adiposity trajectory in adolescence. Study participants included 945 middle school students aged 10 to 16 years (enrolled in 2010 [baseline]) who were followed for 3 years. Among these students, 809 participated in the study at baseline. Pregnant or lactating students were excluded, as well as those with physical or mental disabilities. The investigators assessed body mass index (BMI) and percent body fat (%BF). Findings revealed no protective effects of frequent breakfast consumption and family breakfast against adiposity. At baseline, low BMI and %BF was noted in girls in relation to these behaviors. An increase in %BF was observed during follow-up in relation to these behaviors and persistence of regular breakfast consumption. A greater decrease in %BF was found among boys who increased or decreased family breakfast frequency vs those persistently regular at both time points.
