Eating breakfast is believed to promote a healthy body weight.
Yet, few studies have examined the contribution of energy balance–related behavioral factors to this relation in minority youth.
Dr Suzan Schembre and colleagues from California, USA assessed the associations between breakfast consumption and dietary intake, physical activity, and adiposity before and after accounting for energy intake and physical activity in minority girls.
Cross-sectional data were obtained on body mass index, percentage body fat, dietary intake, and physical activity from 87 Latina, and African American girls 8–17 years of age.
Dietary records were used to categorize girls as more frequent breakfast eaters or less frequent breakfast eaters.

The researchers found that the less frequent breakfast eater group spent 30% less time in moderate-to-vigorous-intensity physical activity, and had a higher percentage body fat.
Moderate-to-vigorous-intensity physical activity accounted for 25% of the relation between breakfast consumption and percentage body fat.
The researchers were unable to show that energy intake was a significant mediator of the relation between breakfast consumption and adiposity in this sample.
Dr Schembre's team concludes, "Evidence suggests that among predominantly overweight minority girls, physical activity, but not energy intake, was associated with both breakfast consumption and adiposity."
"However, a lack of power reduced our ability to detect a significant mediation effect."
"Other unobserved variables likely contribute to this relation."
