Association between maternal lifestyle and preschool nutrition.

Introduction: Many of the health behaviors involved in the emergence of chronic non-communicable diseases (CNCD) are originated in childhood under parental influence. Mothers are the ones most involved in the education and health care of children. Lifestyle (LS) is a social determinant of health. Very few studies tried to understand the influence of maternal LS on child nutrition. Objective: To verify the association between maternal behavioral and non-behavioral LS and nutritional aspects in preschool children. Method: From January 2010 to December 2010, we performed a cross-sectional study with 255 mothers of preschool children who were residents of five different sub-districts in southwestern São Paulo. A proportional stratified random sample was selected using two layers ("schools" and "children"). From the mother, sociodemographic and LS information were collected. From the child, data on anthropometry, sedentary behavior and food intake were collected. The association was calculated using chi-square test and logistic regression. Results: Children who ate minimally processed food were born from mothers with more socially aware non-behavioral LS, while children that ate more processed food were born from mothers with more consumerist non-behavioral LS. No association was found between nutritional characteristics of preschoolers and types of maternal behavioral LS. Children presenting "sedentary behavior" and the habit of eating "ultra-processed foods" had 113% and 84% higher chances, respectively, of being born to mothers that belonged to the "consumerist" cluster. Conclusion: Mothers living a consumerist lifestyle can promote negative influences on child nutrition.
