OBJECTIVES: Poor diet quality during pregnancy or postpartum is associated with increased obesity risk and adverse maternal and child health outcomes. We investigated the association between diet quality trajectories from pregnancy to 3.5 years postpartum and body mass index (BMI) trajectories from prepregnancy to 3.5 years postpartum.
METHODS: We analyzed longitudinal data of 413 women from the Healthy Beginnings Trial. Data were collected at baseline (24-34 weeks gestation) and 1, 2 and 3.5 years postpartum. A 15-item semi-quantitative food frequency questionnaire was used to collect dietary intake. Diet quality was assessed using a modified 2013 Dietary Guideline Index (DGI). Group-based trajectory modelling and multivariable logistic regression estimated diet quality and BMI trajectories and their associations.
RESULTS: Two relatively stable diet quality trajectories and 4 stable BMI trajectories were identified. Women following the low versus the high DGI trajectory from pregnancy to postpartum were more likely to follow the obesity trajectory from prepregnancy to postpartum (adjustment for age, marital status and intervention allocation; OR 1.64; 95% CI: 1.03, 2.62; P = 0.037). The association was no longer significant (OR 1.37; 95% CI: 0.84, 2.24; P = 0.2) after further adjustment for country of birth, educational attainment and pregnancy smoking status.
CONCLUSIONS: A persistent low diet quality trajectory was associated with an obesity trajectory in women, but the association was confounded by sociodemographic factors. These findings highlight the importance of addressing sociodemographic inequities in strategies to improve diet quality and obesity outcomes across the transition to motherhood.
