Cross-National Comparison of Breastfeeding, Malnutrition and Associated Risk Factors among Mexican-Origin Children Living in Mexico and the US

Abstract

To examine breastfeeding, individual and household risk factors for malnutrition (i.e., overweight and stunting) among Mexican-origin children aged 6 to 35 months living in Mexico and the US. We ran logistic regression models using subsamples of the 2012 Mexican National Health and Nutrition Survey, and four waves (2007-2014) of the US National Health and Nutrition Examination Survey. We found evidence for a protective effect of any breastfeeding on stunting in Mexico. Risk factors for overweight and stunting across countries were high- and low-birthweight, correspondingly. An additional risk factor for overweight was introducing complementary foods before 6 months; while being male, living in Mexico and moderate-severe household food insecurity were additional risk factors for stunting. To prevent malnutrition among Mexican-origin children, pre- and post-natal culturally-sensitive policies and interventions in both countries should be aimed toward preventing high- and low-birthweight, and promoting positive maternal health behaviors such as appropriate child feeding practices.
