Patterns of Weight Change One Year after Delivery Are Associated with Cardiometabolic Risk Factors at Six Years Postpartum in Mexican Women.

ABSTRACT: Pregnancy is a contributor to the obesity epidemic in women, probably through postpartum weight retention (PPWR), weight gain (PPWG), or a combination of both (PPWR + WG). The contribution of these patterns of postpartum weight change to long-term maternal health remains understudied. In a secondary analysis of 361 women from the prospective cohort PROGRESS, we evaluated the associations between patterns of weight change one year after delivery and cardiometabolic risk factors at six years postpartum. Using principal component analysis, we grouped cardiometabolic risk factors into: (1) body mass index (BMI), waist circumference (WC), homeostatic model assessment of insulin resistance (HOMA-IR), high-density lipoprotein cholesterol (HDL-c), triglycerides (TG), and glucose; (2) systolic (SBP) and diastolic blood pressure (DBP); and (3) low-density lipoprotein cholesterol and total cholesterol. Using path analysis, we studied direct (patterns of weight change-outcomes) and indirect associations through BMI at six years postpartum. Around 60% of women returned to their pregestational weight (reference) by one year postpartum, 6.6% experienced PPWR, 13.9% PPWG, and 19.9% PPWR + WG. Women with PPWR + WG, vs. the reference, had higher BMI and WC at six years (2.30 kg/m², 95% CI [1.67, 2.93]; 3.38 cm [1.14, 5.62]). This was also observed in women with PPWR (1.80 kg/m² [0.80, 2.79]; 3.15 cm [-0.35, 6.65]) and PPWG (1.22 kg/m² [0.53, 1.92]; 3.32 cm [0.85, 5.78]). PPWR + WG had a direct association with HOMA-IR (0.21 units [0.04, 0.39]). The three patterns of weight change, vs. the reference, had significant indirect associations with HOMA-IR, glucose, TG, HDL-c, SBP, and DBP through BMI at six years. In conclusion, women with PPWR + WG are at high-risk for obesity and insulin resistance. Interventions targeting women during pregnancy and the first year postpartum may have implications for their long-term risk of obesity and cardiovascular disease.

Project description:BackgroundPostpartum weight trajectories and its implications on later cardiometabolic health are not entirely understood.ObjectivesOur objectives were: 1) to characterize maternal weight trajectories from 1 to 24 mo postpartum, 2) to determine the association of prepregnancy BMI, gestational weight gain (GWG), and pregnancy behaviors with the trajectories, and 3) to evaluate the association of weight trajectories with BMI, waist circumference (WC), lipid profile, glucose, insulin resistance, blood pressure, and inflammatory markers at 3 y postpartum.MethodsWe studied 1359 mothers from the prospective cohort Project Viva. Using weights at 1, 6, 12, and 24 mo postpartum, we characterized weight trajectories using a latent class growth model. For objectives 2 and 3, we used multinomial logistic regression and multiple linear regression models, respectively.ResultsAround 85% of women fell into a trajectory of sustained weight loss (1-12 mo) + maintenance (12-24 mo) (reference), 5.7% followed a trajectory characterized by fast weight loss + slight gain, and 9.7% fell into a trajectory of little weight loss + slight gain. Prepregnancy overweight and obesity increased the odds of falling into the fast weight loss + slight gain trajectory, compared with the reference. Prepregnancy overweight [OR 1.57 (95% CI: 1.01, 2.46)] and a higher total GWG rate [3.69 (2.90, 4.68)] increased the odds of falling into the little weight loss + slight gain trajectory, whereas a higher Prudent dietary pattern score was protective [0.73 (0.54, 0.98)]. Women in this trajectory had higher BMI, WC, weight gain from prepregnancy, low-density lipoprotein cholesterol, and inflammatory markers at 3 y postpartum.ConclusionsWomen following a trajectory of little weight loss + slight gain during the first 2 y postpartum had an adverse cardiometabolic profile 3 y after delivery. Targeting diet and GWG during pregnancy and facilitating postpartum weight loss could improve women's long-term health.
