a prospective cohort of 9374 adolescents obesity was defined at
BMI > 95th percentile, overweight as BMI > 85th and <
95th percentile, and normal weight as BMI < 85th percentile
for age and gender.1
mood was assessed with the Center for Epidemiologic Studies Depression
data and several covariates were additionally studied including:
smoking, delinquency, low activity level, self-esteem. All four
covariates were associated with baseline depressed mood, but not
obesity at follow-up.
depressed mood was not significantly associated with baseline
obesity. Number of obese parents was the strongest correlate of
at follow-up was present in 79.7% of obese, 18.5% overweight,
and 1.8% of normal weight at baseline.
bivariate analysis,12.4% of those with depressed mood at baseline
were obese at follow-up compared with 9.4% of those not depressed
at baseline (P = .048).
multivariable analysis, baseline depressed mood independently
predicted follow-up obesity (OR: 2.05; 95% CI: 1.18, 3.56). The
odds of a non-obese adolescent becoming obese doubled if they
had a depressed mood at baseline.
also suggested that depressed mood causes worsening obesity in
those who were obese at baseline.
obesity did not predict follow-up depressed mood, but the folow-up
period may not have been long enough to document this definitively..
