An internet-based weight loss program for low-income, postpartum mothers had a positive 'ripple' effect on the zBMI of infants in the home during the first 6 months of treatment.

Higher acculturation was associated with poorer diet and physical activity behaviors and greater PPWR.

Books and the Internet were the most prevalent information sources reported for prenatal diet, physical activity, and weight control. However, of all sources, only physician provision of information was associated with reduced odds of excessive GWG.

Background Bisphenol exposure is widespread and correlated with diabetes and cardiovascular disease. Previous intervention studies have successfully lowered bisphenol exposure among women of normal weight. The primary objective of this study was to develop and test the feasibility of a 3-week behavioral change intervention, rooted in social cognitive theory, to lower a broad range of bisphenols (BPA, BPS, and BPF) in women with obesity. Methods Thirty women with obesity (31.1 ± 5.6 kg/m2, 21.1 ± 3.1 years) were randomly assigned to an intervention or control. The intervention included weekly face-to-face meetings to reduce bisphenol exposures from food, cosmetics, and packaged products. Fasting urinary bisphenols, creatinine, and weight were assessed at study entry and after 3 weeks. Results The intervention was evaluated as feasible (100% of enrollment and recruitment, 96% of retention and attendance at lesson plan visits, and 96% of a collection of urine samples). Adherence to the intervention was estimated based on completion of self-monitoring records; the number of daily records completed was 7.7 ± 1.3 (mean ± SD) after week 1, 7.1 ± 1.5 after week 2, and 4.4 ± 0.9 after week 3. In secondary analysis, there was a significant treatment × time effect on creatinine-corrected urinary BPS (− 1.42 μg/g creatinine in the intervention vs. − 0.09 μg/g creatinine in the control group). Conclusion In women with obesity, the 3-week intervention was considered feasible with promising preliminary results of decreasing BPS concentrations. These data warrant future large-scale clinical trial interventions to reduce bisphenol exposure and determine whether reductions in bisphenols positively impact diabetes and cardiovascular disease risk markers. This study was retroactively registered at ClinicalTrial.gov Identifier NCT03440307.

Gaining weight in pregnancy is important for the health of the mother and child. However, after having a baby, if a mother keeps the extra weight she gained during pregnancy, this can be harmful to her long-term health. This study tested whether an Internet weight-loss program could help mothers to lose weight after having a baby. We worked with WIC, which is a program that gives lowincome families food and support. Half of the women in the study received regular WIC and half received WIC plus an Internet weight-loss program. We found that the Internet program helped mothers lose five more pounds than regular WIC, and it also helped more mothers get back to the weight that they were before pregnancy. WIC serves half of all US mothers; the Internet weight-loss program in WIC could help many women get closer to the weight they were before pregnancy and avoid weight-related diseases later in life.
