UWCB, Unhealthy Weight Control Behaviour.
P-values are bolded if statistically significant at the 0·05 significance level.
*
Logistic regression models with robust standard errors were used to estimate marginal probabilities and 95 % CI for each binary outcome variable adjusted for parental education, race/ethnicity, age, sex and potential clustering by school. Similarly adjusted multiple regression models with robust standard errors were used to estimate means and 95 % CI for mean number of breakfast, lunch and dinner outcomes.
