Abstract Background High risk of bias associated with missing outcome data (MOD) in meta-analyses (MAs) of the effects of lifestyle interventions during pregnancy on postpartum weight retention (PPWR), casts doubt on whether such interventions can be relied upon as truly effective, since estimates are deemed valid only if MOD was missing at random (MAR). Methods We conducted a systematic overview of MAs to examine the impact of MOD on the estimation of meta-analytic summary intervention effects and conducted sensitivity analyses using pattern mixture models and informative missingness parameters (describing how the outcome in the missing participants may be related to the outcome in the completers), to ascertain the robustness of the estimates to reasonable deviations from the MAR assumption. Results Three relevant MAs were identified, all with high MOD rates in the RCTs included (median>30%), and all reporting beneficial intervention effects on PPWR (in kg) estimated based on complete case analyses: [-0.78 (95%CI: -1.39,-0.16), -0.81 (-1.57,-0.06), and -0.94 (-1.52,-0.37)] in MAs of any lifestyle, exercise, or diet + exercise interventions, respectively. In plausible scenarios where the outcome for the intervention group in participants with vs without MOD was worse (by 0.5kg), effect estimates were attenuated in all and no longer significant in 2 of the MAs [-0.58 (-1.29,0.13), -0.70 (-1.50,0.10) and -0.88 (-1.73,-0.02)]. Conclusions Statistical significance was retained when all 19 RCTs identified across MAs were meta-analysed: -0.63 (-0.17,-0.08). Key messages The clinical relevancy of effects of this magnitude remains unclear.

Abstract Objectives Breastfeeding is a potentially modifiable factor associated with less postpartum weight retention; however, in the United States women with lower socioeconomic status (SES) are less likely to initiate breastfeeding and, therefore, may be at higher risk for long-term weight retention. We sought to describe associations between duration of breastfeeding with postpartum weight retention and later BMI, and to determine whether associations varied by SES. Methods Maternal and infant data (n = 2144 dyads) are from the Geographic Research on Wellbeing survey (GROW), a follow-up study of California's annual statewide-representative Maternal and Infant Health Assessment. Pre-pregnancy BMI was obtained from self-report; at 4–10y postpartum, breastfeeding history and self-reported body weight were collected. Multivariable linear regression was used to examine associations between breastfeeding and long-term maternal body size. SES was calculated as a composite score of % federal poverty threshold plus education and was dichotomized. Results Overall, mean prepregnancy BMI was 24.9 kg/m,2 while long-term weight retention 4–10 y postpartum was 4.0 kg. The sample average breastfeeding duration was 8.5 months with 61% meeting the World Health Organization (WHO) recommendations for 6 months of breastfeeding. In adjusted models, compared to women who did not meet recommendations, women who met WHO recommendations had slightly lower long-term postpartum weight retention (b = −1.06 kg, CI: −1.93, −0.25, p = 0.01) and a small reduction in BMI (b = −0.4 kg/m,2 95% CI −0.74, −0.08; p = 0.02). Compared to higher SES women, fewer lower SES women ever breastfed (89% vs 74%, p < .0001) or met WHO recommendations (70% vs 51%, p < .0001). Lower SES women had higher prepregnancy BMI (25.9kg/m2 vs 23.5, p < .0001), and had greater long-term weight retention 4–10 y postpartum (5.68kg vs. 1.83, p < .0001). In SES stratified adjusted models, there were no differences in associations between breastfeeding with long-term weight retention or BMI. Conclusions Breastfeeding was associated with long term maternal postpartum weight status. Six months of breastfeeding was associated with lower long-term postpartum weight retention and lower BMI at 4–10 years postpartum, and effects did not vary by socioeconomic status.

The Impact

Abstract The aim of this study was to investigate the association between daily Se intake and postpartum weight retention (PPWR) among Chinese lactating women, and the impact of their Se nutritional status on infants’ physical development. Se contents in breast milk and plasma collected from 264 lactating Chinese women at the 42nd day postpartum were analysed with inductively coupled plasma MS. Daily Se intake was calculated based on plasma Se concentration. The dietary data of 24-h records on three consecutive days were collected. Infant growth status was evaluated with WHO standards by Z-scores. Linear regression analyses and multinomial logistic regression were conducted to examine the impact of Se disequilibrium (including other factors) on PPWR and growth of infants, respectively. The results indicated that: (1) the daily Se intake of the subjects was negatively associated with their PPWR (B = −0·002, 95 % CI − 0·003, 0·000, P = 0·039); (2) both insufficient Se daily intake (B = −0·001, OR 0·999, 95 % CI 0·998, 1·000, P = 0·014) and low level of Se in milk (B = −0·025, OR 0·975, 95 % CI 0·951, 0·999, P = 0·021) had potential associations with their infants’ wasting, and low level of Se in milk (B = −0·159, OR 0·853, 95 % CI 0·743, 0·980, P = 0·024) had a significant association with their infants’ overweight. In conclusion, the insufficient Se nutritional status of lactating Chinese women was first found as one possible influencing factor of their PPWR as well as low physical development of their offspring.
