Variables considered but not retained in the model include the following: child's sex, mother's mental health, grandparents in home, father plays frequently with child, mother received alimony, food secure and monthly household per capita food consumption. Food security is a composite of 18 variables derived from standardised questions from the Food Insecurity and Hunger Module, adapted for Peru (Vargas & Penny 2010). *Unless otherwise noted, data come from round 2 when children were 5 years of age. †Data come from round 1 when children were 1 year of age. ‡Data come from both round 1 and round 2.
