For women of reproductive age, excessive gestational weight gain and/or postpartum weight retention can increase the risk of obesity. This systematic review evaluates the effectiveness of lifestyle modification control trials that utilize exercise interventions, with or without dietary intervention, on weight loss among postpartum women. A search of randomized clinical trials (RCT) was performed using the follow databases and the bibliography of candidate studies: MEDLINE, Web of Science, EMBASE, CENTRAL/Cochrane and Physiotherapy Evidence Database. English language RCT papers published up to 31 October 2012, which present changes on maternal body weight from baseline to the end of exercise intervention were included. The primary meta-analysis examined the effects of exercise interventions, with or without complementary dietary intervention, on weight loss during the postpartum period compared with usual standard of care. Five subgroup analyses were performed to examine differences in study interventions and exercise modalities: duration of intervention, quality of study methodology, supervision of exercise intervention, exercise intervention goals used and the type of dietary intervention. In total 11 studies met eligibility criteria with 769 participants, 409 under intervention and 360 in the control group. The primary meta-analysis included all 11 studies and found a mean difference (MD) on weight loss of -2.57 kg (95% CI -3.66 to -1.47). The subgroup analysis demonstrated that the most effective interventions in reducing weight in postpartum women were exercise programs with objectively defined goals, such as the use of heart rate monitors or pedometer (MD of -4.09 kg-95% CI -4.94 to -3.25, I(2)=0%) and exercise combined with intensive dietary intervention (MD of -4.34 kg-95% CI -5.15 to -3.52, I(2)=0%). Thus, there is benefit from overall lifestyle interventions on weight loss in postpartum women and exercise plus intensive diet and objective targets are the most effective intervention strategies.

BACKGROUND AND PURPOSE:Pre-eclampsia is a serious clinical gestational disorder occurring in 3%-5% of all human pregnancies and characterized by endothelial dysfunction and vascular complications. Offspring born of pre-eclamptic pregnancies are reported to exhibit deficits in cognitive function, higher incidence of depression, and increased susceptibility to stroke. However, no brain imaging reports exist on these offspring. We aimed to assess brain structural and vascular anatomy in 7-to 10-year-old offspring of pre-eclamptic pregnancies compared with matched controls.

ObjectiveTo prospectively examine whether children of women with a pregnancy affected by severe pre-eclampsia (PE), compared to children of women without a PE-affected pregnancy, have differences in neurodevelopmental performance up to 5 years of age.DesignProspective cohort study.SettingTertiary care centre.ParticipantsWomen were recruited following a PE-affected pregnancy. After each PE participant was recruited, the next normotensive woman without a prior history of PE and matched by parity, maternal age and race was invited to participate. Women with a history of chronic hypertension, diabetes or renal disease were excluded. Total enrolment included 129 PE-affected and 140 normotensive mothers.Outcome measuresThe primary outcome measure was failure of the Ages and Stages Questionnaire (ASQ). The ASQ was completed yearly, until age 5.ResultsA significant difference was found in the proportion of ASQ categories failed in year 3 (p<0.05), and this approached significance in years 1 and 4 (p<0.10 and p<0.15, respectively). At year 1, the number of ASQ categories failed was significantly greater among children born to PE mothers. A subgroup analysis revealed that a significant proportion of PE children born preterm (<37 weeks) failed the ASQ in years 3 and 4 (p<0.05), and when failed, those who were preterm failed significantly more categories (p<0.05). A trend towards increased failure in the gross motor category was found. There was a significant positive correlation between maternal lifetime CVD risk score and number of ASQ categories failed at years 1 and 3 (p<0.05).ConclusionsSevere PE is associated with other adverse pregnancy outcomes, including intrauterine growth restriction and preterm birth, all of which are associated with increased neurodevelopment delays. Thus, PE indicates a need for early screening and intervention at the neurodevelopmental level to improve children's long-term health, with larger studies required to tease out contributing factors.

Purpose The use of assisted reproductive technology (ART) has increased in the last 2 decades and continuous surveillance is needed. This systematic review aims to assess the risk of adverse neonatal outcomes (preterm birth [PTB], low birth weight [LBW], small-for-gestationalage [SGA] and large for gestational-age [LGA]), in singleton pregnancies conceived by fresh or frozen embryo transfer (FET) compared to spontaneous conceptions. Methods Cohort studies were identified from MEDLINE, Embase, Cochrane Library (January 2019), and manual search. Meta-analyses were performed to estimate odds ratios (OR) using random effects models in RevMan 5.3 and I-squared (I2) test > 50% was considered as high heterogeneity. Results After 3142 titles and abstracts were screened, 1180 full-text articles were assessed, and 14 were eligible. For fresh embryo transfer, the pooled ORs were PTB 1.64 (95% CI 1.46, 1.84); I2 = 97%; LBW 1.67 (95% CI 1.52, 1.85); I2 = 94%; SGA 1.46 [95% CI 1.11, 1.92]; I2 = 99%, LGA 0.88 (95% CI 0.80, 0.87); I2 = 80%). For frozen, the pooled ORs were PTB 1.39 (95% CI 1.34, 1.44); I2 = 0%; LBW 1.38 (95% CI 0.91, 2.09); I2 = 98%; SGA 0.83 (95% CI 0.57, 1.19); I2 = 0%, LGA 1.57 (95% CI 1.48, 1.68); I2 = 22%). Conclusions When compared with spontaneous pregnancies, fresh, but not frozen was associated with LBW and SGA. Both fresh and frozen were associated with PTB. Frozen was uniquely associated with LGA. Despite improvements in ART protocols in relation to pregnancy rates, attention is needed towards monitoring adverse neonatal outcomes in these pregnancies.

Background: Breastfeeding is associated with lower cardiovascular (CV) risk over the long-term, however, less is known about its immediate effects among women with a recent complicated pregnancy. The objective of this study is to investigate the short-term effects of breastfeeding on markers of cardiovascular disease risk among women *6 months after a pregnancy complicated by a hypertensive disorder, gestational diabetes, intrauterine growth restriction, abruption, or preterm birth. Materials and Methods: Our cross-sectional analysis includes 622 women seen at 6 months postpartum (interquartile range: 5.7-6.7) between November 2011 and December 2017 at a tertiary care center. Self-reported breastfeeding status and measured CV risk factors were assessed at the same visit. CV risk factors were compared between women who did not breastfeed (n = 100, 16%), those who breastfed for less than 6 months (n = 315, 51%), and those who breastfed for 6 months or more (n = 207, 33%) using multivariate logistic and linear regression. Results: Increased breastfeeding duration significantly decreased the likelihood of metabolic syndrome (adjusted odds ratio [95% confidence interval; CI]: 0.89 [0.79-0.99]), abnormal fasting glucose (0.79 [0.64-0.96]), and ratio of total cholesterol to high-density lipoprotein-cholesterol (HDL-C) (0.86 [0.78-0.95]). Furthermore, body mass index (estimated beta coefficients [95%
