Pre-pregnancy Health Behaviors and Gestational Weight Gain Among Hispanic/Latino Women: Hispanic Community Health Study/Study of Latinos.

Abstract

To examine the association between preconception diet quality, sedentary behavior, and physical activity with gestational weight gain (GWG) among Hispanic/Latina women. This was a retrospective cohort study of participants from visits 1 and 2 of the Hispanic Community Health Study/Study of Latinos and singleton pregnancies between the 2 visits. Diet quality (alternative healthy eating index/AHEI-2010), sedentary behaviors, and physical activity (global physical activity questionnaire) were measured at visit 1 and accounted for preconception health behaviors. GWG was evaluated as a continuous and categorical variable according to the 2009 Institute of Medicine guidelines (inadequate, adequate, excessive). Linear and generalized logit survey regressions were used to study the association between health behaviors and GWG, using adequate GWG as the reference. Of the 457 women included, deliveries occurred at 3.2years (mean) from visit 1; 48.7% of women had excessive GWG. Mean AHEI-2010 scores were < 45% for women of all Hispanic/Latina backgrounds. There was no association between each 10-unit increase in AHEI-2010 or a 500kcal/day increase in energy intake for mean and categorical GWG. There was no association between 30min/day higher sedentary behavior, 30min/day higher physical activity, or meeting the 2008 US physical activity guidelines for mean and categorical GWG. We did not find any association between diet quality, sedentary behavior, and physical activity at visit 1 with GWG in pregnancies occurring between visits 1 and 2. We noted widespread poor diet quality as measured by the AHEI-2010 and low levels of physical activity among Hispanic/Latina women.
