Non-nutritive sweeteners (NNS) are increasingly consumed by children and pregnant women around the world, yet their long-term health impact is unclear. Here, we review an emerging body of evidence suggesting that early-life exposure to NNS may adversely affect body composition and cardio-metabolic health. Some observational studies suggest that children consuming NNS are at increased risk for obesity-related outcomes; however, others find no association or provide evidence of confounding. Fewer studies have examined prenatal NNS exposure, with mixed results from different analytical approaches...

INTRODUCTION: We aimed to investigate the change in prevalence of overweight and obesity in pregnant Danish women from 2004 to 2012 and investigate whether increasing parity was associated with a change in BMI prevalence. MATERIAL AND METHODS: We obtained a population-based cohort from the Danish Medical Birth registry consisting of all Danish women giving birth from 2004-2012 (n=572 321). This registry contains information on 99.8% of all births in Denmark. We calculated the overall change in pre-pregnancy BMI-status among pregnant women in Denmark, and a multiple linear regression model with adjustment for several potential confounders in combination with a paired t-test was used to examine the change in pre-pregnancy BMI with increasing parity...

BACKGROUND: Phthalates and phenols are suspected endocrine disrupting chemicals that may adversely impact fetal outcomes following in utero exposure. Understanding predictors of exposure to phthalates and phenols during the prenatal period is important. METHODS: We measured urinary concentrations of 15 phthalate metabolites and 11 phenols in 446 pregnant women enrolled in the Healthy Start pre-birth cohort. Creatinine-adjusted geometric means (GM) for each urinary biomarker were compared across categories of potential sociodemographic and dietary predictors...

STUDY QUESTION: What are the impacts of elevated testosterone (T) and an obesogenic western-style diet (WSD), either independently or together, on fertility and metabolic adaptations of pregnancy in primates? SUMMARY ANSWER: Testosterone increases the time to achieve pregnancy, while a WSD reduces overall fertility, and the combination of testosterone and WSD additionally impairs glucose tolerance and causes pregnancy loss. WHAT IS KNOWN ALREADY: Both hyperandrogenemia and obesity are hallmarks of polycystic ovary syndrome, which is a leading cause of infertility among women worldwide...

The rapidly shifting field of epigenetics has expanded scientific understanding of how environmental conditions affect gene expression and development. This article focuses on two ongoing clinical trials-one in the United States and one in the United Kingdom-that have used epigenetics as the conceptual basis for testing the relationship between nutrition and obesity during pregnancy. Drawing on ethnographic research, I highlight the different ways that clinical scientists interpret epigenetics to target particular domains of the environment for prenatal intervention...

Sleep-disordered breathing is more common in hypertensive disorders during pregnancy; however, most studies have not adequately accounted for the potential confounding impact of obesity. This study evaluated the frequency of sleep-disordered breathing in women with gestational hypertension and pre-eclampsia compared with body mass index- and gestation-matched normotensive pregnant women. Women diagnosed with gestational hypertension or pre-eclampsia underwent polysomnography shortly after diagnosis. Normotensive controls body mass index-matched within ±4 kg m-2 underwent polysomnography within ±4 weeks of gestational age of their matched case...

Gestational diabetes mellitus (GDM) is defined as hyperglycemia detected during pregnancy and its risk is increased with obesity. Chemerin, an adipokine, has been proposed as potential mediators of insulin resistance in GDM. This case-control study was designed to assess the relation between chemerin SNPs rs4721 (or rs10278590) and rs17173608 and the development of GDM. One hundred thirty GDM pregnant women with GDM and 160 healthy pregnant women were enrolled in this study. The diagnosis of GDM was based on the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria...
