^aFinal models were run separately for the child anthropometric indexes weight for height, height for age and weight for age. Results presented for variables other than the anthropometric indexes were derived from models containing weight for height as the only child anthropometric index.

^bNot significant. If noted, these variables were not included in the final multivariate model.
