“…We used the Mexican Association of Marketing Research and Public Opinion Index (AMAI ), a 13x6 battery based on family possessions, living conditions, and education, to categorize six socioeconomic status (SES) levels ranging from lowest (1) to highest (6) SES within the cohort [16]. We reclassi ed these categories as low (1, 2), medium (3), and high (4,5,6). Women self-reported their prepregnancy weight (kg) at six months prior to pregnancy.…”

“…The weight gain resulting from fetal components and body water is lost in the rst weeks of postpartum; therefore, the remaining gained weight corresponds to the increase in maternal fat mass [1][2][3][4]. Gestational fat mass accretion may be used as body storage to support breastfeeding [5]. Even so, a higher fat mass accretion during pregnancy may in uence postpartum weight retention [6].…”

Background Woman's weight changes during pregnancy and postpartum contribute to obesity and health outcomes later in life. This study aimed to identify and characterize weight change trajectories from pregnancy to one year postpartum among adult women. Methods We used data from an ongoing cohort of healthy adult women (n = 819) with singleton pregnancies from 2007–2011. Sociodemographic data, pre-pregnancy body weight, and sedentary and breastfeeding practices were collected. We applied a group-based trajectory modeling to distinguish weight change measured in the second and third trimesters of pregnancy and at one month, six, and 12 months postpartum. Multinomial regression models were run to characterize each trajectory. Results We identified six weight change trajectories with the main difference in the patterns followed after one month of delivery. One in three women (36.7%), classified in some of the three postpartum weight gain trajectories, started to gain weight at the second or third trimester of the first year postpartum. Women who followed some of these trajectories were more likely to have higher age, obesity before pregnancy, < 10 years of schooling, and partner, compared with women (10.7%, n = 87) in a postpartum sustained-fast-lost-weight trajectory (p < 0.05). Conclusions Women with obesity before pregnancy have a higher odd of regained gestational weight after delivery without reaching their pre-pregnancy weight. The first six months postpartum are key to establishing obesity prevention strategies. Further research is needed to evaluate the effect of the interventions that prevent substantial weight gain through reproductive years in high-risk women.
