Association of breakfast intake with obesity, dietary and physical activity behavior among urban school-aged adolescents in Delhi, India: results of a cross-sectional study
Background In developed countries , regular breakfast consumption is inversely associated with excess weight and directly associated with better dietary and improved physical activity behaviors . Our objective was to describe the frequency of breakfast consumption among school-going adolescents in Delhi and evaluate its association with overweight and obesity as well as other dietary , physical activity , and sedentary behaviors . Methods Design : Cross-sectional study . Setting : Eight schools ( Private and Government ) of Delhi in the year 2006 . Participants : 1814 students from 8th and 10th grade s ; response rate was 87.2 % ; 55 % were 8th grade rs , 60 % were boys and 52 % attended Private schools . Main outcome measures : Body mass index , self-reported breakfast consumption , diet and physical activity related behaviors , and psychosocial factors . Data analysis : Mixed effects regression models were employed , adjusting for age , gender , grade level and school type ( SES ) . Results Significantly more Government school ( lower SES ) students consumed  breakfast  daily as compared to Private school ( higher SES ) students ( 73.8 % vs. 66.3 % ; p<0.01 ) . More 8th grade rs consumed breakfast daily vs.10th grade rs ( 72.3 % vs. 67.0 % ; p<0.05 ) . A dose – response relationship was observed such that overall prevalence of overweight and obesity among adolescents who consumed breakfast daily ( 14.6 % ) was significantly lower vs. those who only sometimes ( 15.2 % ) or never ( 22.9 % ) consumed breakfast ( p<0.05 for trend ) . This relationship was statistically significant for boys ( 15.4 % vs. 16.5 % vs. 26.0 ; p<0.05 for trend ) but not for girls . Intake of dairy products , fruits and vegetables was 5.5 ( 95 % CI 2.4 - 12.5 ) , 1.7 ( 95 % CI 1.1 - 2.5 ) and 2.2 ( 95 % CI 1.3 - 3.5 ) times higher among those who consumed breakfast daily vs. those who never consumed breakfast . Breakfast consumption was associated with greater physical activity vs. those who never consumed breakfast . Positive values and beliefs about healthy eating ; body image satisfaction ; and positive peer and parental influence were positively associated with daily breakfast consumption , while depression was negatively associated . Conclusion Daily breakfast consumption is associated with less overweight and obesity and with healthier dietary- and physical activity-related behaviors among urban Indian students . Although prospect i ve studies should confirm the present results , intervention programs to prevent or treat childhood obesity in India should consider emphasizing regular breakfast consumption
