Abstrakt: Objective: To evaluate the effect of exclusive breastfeeding in <6mo (EBF<6mo) on the relationship between food insecurity (FI) and nutritional status, in Mexican infants.
Materials and Methods: We analyzed the sample of 12-49y women and their children <2y from the national survey ENSANUT 2012 (n = 4 022). Breastfeeding indicators from WHO-2008 were calculated. We estimated the effect modifier EBF<6mo of the relationship between FI and weight length (Z W/L) and length for age (Z L/A) Z score.
Results: The EBF<6mo was lower in households (hh) with moderate and severe FI than in those with food security (FS) or mild FI hh. Only EBF<6mo infants from hh with moderate and severe FI showed greater Z W/L (0.44) than those without EBF<6mo (p= 0.038, one-tailed). Score Z W/L of infants from hh FS did not vary according to EBF<6mo.
Conclusion: EBF<6mo in Mexican infants is associated with better weight for length in households with moderate and severe FI. Breastfeeding promotion, protection and support must be targeted mainly at the most vulnerable, food insecure families.
