Maternal pre-pregnancy overweight/obesity and gestational diabetes interaction on delayed breastfeeding initiation.

Gender and social mobility modify the effect of birth weight on total and central obesity.

Background: Little is known about the interaction between gender and low birth weight (LBW) and lifelong social mobility as an explanation of the etiology of obesity. The aim of the present study was to evaluate total and central obesity according to gender, LBW and social mobility, within the context of the epidemiological transition in middle-income countries. We hypothesize that there are more pronounced metabolic consequences of social mobility for women born with LBW.
