“…Despite strengths, there are some limitations of our study. Self‐reported height and weight may have introduced misclassification bias; however, in women of reproductive age, self‐reported height and weight differs only slightly from direct measures and has been found to give valid estimates in research and for clinical use 28 . Data on height and weight were collected before the outcome GDM, and possible misclassification of BMI would therefore be independent of the outcome and non‐differential 29 .…”

Objective To estimate recurrence risk of gestational diabetes mellitus (GDM) by interpregnancy weight change. Design Population‐based cohort study. Setting and population Data from the Swedish (1992–2010) and the Norwegian (2006–2014) Medical Birth Registries on 2763 women with GDM in first pregnancy, registered with their first two singleton births and available information on height and weight. Methods Interpregnancy weight change (BMI in second pregnancy minus BMI in first pregnancy) was categorised in six groups by BMI units. Relative risks (RRs) of GDM recurrence were obtained by general linear models for the binary family and adjusted for confounders. Analyses were stratified by BMI in first pregnancy (<25 and ≥25 kg/m2). Main outcome measure GDM in second pregnancy. Results Among overweight/obese women (BMI ≥25), recurrence risk of GDM decreased in women who reduced their BMI by 1–2 units (relative risk [RR] 0.80, 95% CI 0.65–0.99) and >2 units (RR 0.72, 95% CI 0.59–0.89) and increased if BMI increased by ≥4 units (RR 1.26, 95% CI 1.05–1.51) compared wth women with stable BMI (−1 to 1 units). In normal weight women (BMI <25), risk of GDM recurrence increased if BMI increased by 2–4 units (RR 1.32, 95% CI 1.08–1.60) and ≥4 units (RR 1.61, 95% CI 1.28–2.02) compared with women with stable BMI. Conclusion Interpregnancy weight loss reduced risk of GDM recurrence in overweight/obese women. Weight gain between pregnancies increased recurrence risk for GDM in both normal and overweight/obese women. Our findings highlight the importance of weight management in the interconception window in women with a history of GDM. Tweetable abstract Interpregnancy weight loss reduces recurrence of gestational diabetes mellitus in overweight/obese women.

“…Pre-pregnancy BMI was calculated from self-reported weight, which may be inaccurate however more likely to underestimate obesity in our sample and thus the overall effect. Furthermore, the magnitude of this reporting bias is likely to be negligible 40 . The definition of severe pre-eclampsia used in our study is as per the French national clinical guidelines at the time of protocol development, which have since changed 28 .…”

We investigated the extent to which pre-pregnancy obesity mediates the association between maternal place of birth and severe pre-eclampsia in the precARe cohort of pregnant women in paris (n = 9,579). Adjusted path analysis logistic regression models were used to assess the role of pre-pregnancy obesity as a mediator in the association between maternal place of birth and the development of severe pre-eclampsia. We calculated 1. adjusted odds ratios and 95% confidence intervals for the total exposure-outcome association and for the direct and indirect/obesity-mediated components 2. the indirect/obesity-mediated effect. Ninety-five (0.99%) women developed severe pre-eclampsia, 47.6% were non-European immigrants, 16.3% were born in Sub-Saharan Africa, and 12.6% were obese (BMI > = 30 kg/m 2 ). Women experiencing severe pre-eclampsia were more likely to be from Sub-Saharan Africa (p = 0.023) and be obese (p = 0.048). Mothers from Sub-Saharan Africa had an increased risk of severe pre-eclampsia compared to European-born mothers (aOR 2.53, 95% CI 1.39-4.58) and the obesity-mediated indirect effect was 18% of the total risk (aOR 1.18, 95%CI 1.03-1.35). In conclusion, Sub-Saharan African immigrant women have a two-fold higher risk of developing severe pre-eclampsia as compared to European-born women, one-fifth of which is mediated by pre-pregnancy obesity. Our results quantify the potential benefit of decreasing obesity among at-risk women.Pre-eclampsia, a disorder of pregnancy characterized by hypertension and proteinuria, affects 3-5% of pregnancies globally 1-3 and is one of the leading causes of maternal and neonatal mortality and morbidity in developed countries 2,4-7 . Severe pre-eclampsia is characterized by higher blood pressures and more profound organ dysfunction than mild pre-eclampsia 8 and constitutes the largest attributable fraction of severe morbidity due to hypertensive disorders in pregnancy 5 . Overall, the prevalence of pre-eclampsia has been declining in some European countries and Australia but continues to rise in the United States 5,9,10 . The increase in pre-eclampsia in the United States is driven specifically by higher rates of severe disease: while mild pre-eclampsia declined between 1980 and 2010, from 3.1% to 2.5%, severe pre-eclampsia increased from 0.3% to 1.4% 11 .There are known social and medical factors associated with a differential risk of developing pre-eclampsia. Maternal origin has been linked to disparities in rates of pre-eclampsia in various settings. In Europe, immigrant our understanding of the complex relationships between maternal origin, obesity, and severe pre-eclampsia, they also highlight the need to better understand other drivers of severe maternal outcomes among immigrant women. Future investigations should focus on better elucidating the role of other modifiable mediators, such as those pertaining to quality of care and the health care system factors in an effort to improve Data availabilityDue to ethical restrictions, data will be made available on request to A.

“…In study I, we used self-reported prepregnancy or measured early pregnancy BMI. Although previous studies have shown that self-reported BMI is reliable, (101,102) it may be a potential source of bias. The self-reported pre-pregnancy BMI or early pregnancy BMI employed in studies I-IV is preferred to maternal BMI based on weight at delivery.…”

Maternal obesity, duration of labor and the role of leptin

Background: The prevalence of obesity substantially increases in pregnant women. Maternal obesity is associated with adverse maternal and neonatal outcomes. The increased risk for cesarean section present in obese women has been related to potential impaired uterine contractility. The mechanism that underlies this theory is not clear. In vitro studies have shown that leptin, produced by adipose tissue and the placenta, exerts an inhibitory effect on myometrial contractility. The aim of this thesis was to evaluate the labor process in relation to maternal body mass index (BMI) and the clinical role of leptin in this process.

Comparison of self‐reported and directly measured weight and height among women of reproductive age: a systematic review and meta‐analysis

Abstract: This review shows that self-reported weight and height of women of reproductive age differs slightly from direct measures. We consider that the magnitude at which self-reported data over- or underestimates the real value, is negligible regarding clinical and research use.
