Article
Full-text available
Background: About 50% of women experience lumbopelvic pain (LBPP) during their pregnancy. LBPP has negative repercussions on sleep, social and sexual life, physical and work capacity, and psychological health and contributes to physical inactivity. The benefits of LBPP prevention or treatment in pregnant women through specific exercises should the...
Article

Up to 86% of pregnant women will have lumbopelvic pain during the 3rd trimester of pregnancy and women with lumbopelvic pain experience lower health-related quality of life during pregnancy than women without lumbopelvic pain. Several risk factors for pregnancy-related lumbopelvic pain have been identified and include history of low back pain, prev...

Physical activity (PA) is a part of a healthy pregnancy. To date, no consumer-based activity monitors have been validated with this population. The aim of this study was to validate the Fitbit Zip and Fitbit Flex monitors in free-living conditions with pregnant women using the ActiGraph GT3X as the ?gold standard?. We compared the accuracy of the F...
Article
Physical activity (PA) behaviours after assisted reproductive technology (ART) may influence its success. Bedrest is frequently recommended immediately after intrauterine insemination (IUI) or embryo transfer (ET), and women are also commonly advised to restrict PA after ART. However, these recommendations are not grounded on evidence-based informa...
Article
The transition to menopause is associated with a myriad of physiological changes including unstable hormone levels (estrogen, progesterone) resulting in hot flashes, sleep deprivation, weight gain, mood swings and is associated with increased risk of osteoperosis and cardiometabolic disease. Exercise is a critical component of health and wellbeing...
Article

Gestational diabetes mellitus (GDM) is defined as 'carbohydrate intolerance resulting in hyperglycemia of variable severity with onset or first recognition during pregnancy'. GDM is associated with several detrimental health consequences during pregnancy and delivery for both mother and baby. The largest public health impact of GDM is through its r...
Article
Full-text available
The developmental origins of health and disease hypothesis contend that fetal and early postnatal environmental factors, in particular nutrition, influence long-term health in offspring. Accumulating evidence in humans show that fetal under- and over-nutrition induce long-term changes in gene expression and influence phenotypes in the offspring thr...
Article
It is now well accepted that offspring exposed to maternal undernutrition, obesity, or gestational diabetes mellitus have an increased risk for chronic diseases later in life, supporting the theory of the early origins of chronic diseases. However, the molecular mechanisms through which the exposure to an altered in utero environment translates int...
Article
To evaluate whether the timing of excessive maternal weight gain in a cohort of women following current guidelines for healthy living during pregnancy affects neonatal adiposity at birth. One hundred seventy-two healthy women who were at least 18 years old with body mass indexes (BMIs) of at least 18.5 were recruited between 16 weeks and 20 weeks o...
Article
Offspring exposed to gestational diabetes mellitus (GDM) have an increased risk for chronic diseases, and one promising mechanism for fetal metabolic programming is epigenetics. Therefore, we postulated that GDM exposure impacts the offspring's methylome and used an epigenomic approach to explore this hypothesis. Placenta and cord blood samples wer...
Article
The actual pathophysiology behind gestational diabetes mellitus (GDM) is still unclear but a deterioration in insulin resistance beyond that induced by pregnancy, combined with beta cell dysfunction, play key roles. Interventions that help improve glucose tolerance by attenuating pregnancy-induced insulin resistance or achieve glycemic control may...
Article
Full-text available
. The period surrounding pregnancy has been identified as a risk period for overweight/obesity in both mother and child because of excessive gestational weight gain (GWG). The promotion of a healthy GWG is therefore of paramount importance in the context of the prevention of obesity in the current and next generations. Objective . To provide a comp...
Article
Exercise may influence glucose metabolism during pregnancy. We examined the effect of exercise intensity and duration on capillary glucose responses in pregnant women at low and high risk for gestational diabetes mellitus (GDM) who followed a modified GDM meal plan. Randomization occurred at study entry (16–20 weeks' gestation) into a low-intensity...

Walking is the most popular activity during pregnancy and may confer an aerobic benefit. However, the minimum intensity threshold of a maternal walking program for an aerobic conditioning response is unknown. The purpose was to examine the effect of a walking program of a low-intensity (LI, 30% heart rate reserve, HRR) or vigorous-intensity (VI, 70...
Article
This study aimed to evaluate the effect of an exercise program of two different intensities, with nutritional control, on gestational weight gain (GWG), infant birth weight, and maternal weight retention at 2 months postpartum (2 mopp). Pregnant women (prepregnancy body mass index = 18.5-24.9 kg·m) were randomized at study entry (16-20 wk of gestat...
Article
Full-text available
Exercise training improves glucose homeostasis, but large inter-individual differences are reported, suggesting a role of genetic factors. We investigated whether variants either confirmed or newly identified as diabetes susceptibility variants through genome-wide association studies (GWAS) modulate changes in phenotypes derived from an IVGTT in re...
Article
Full-text available
Although several candidate gene polymorphisms (SNPs) have been associated with increased risk of type 2 diabetes mellitus (T2DM), relatively few studies have assessed the ability of T2DM candidate genes to assess the risk of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and T2DM beyond the information provided by clinical risk f...
Article
Full-text available
Genome-wide association studies have led to the identification of several susceptibility genes for type 2 diabetes mellitus (T2DM). The objective of this study was to test the hypothesis that the associations between single nucleotide polymorphisms (SNPs) in these genes and adiposity and glucose homeostasis-related phenotypes are influenced by diet...
Article
Full-text available
The peroxisome proliferator-activated receptor-gamma ( PPARG) Pro12Ala and the PPARG co-activator-1alpha ( PPARGC1A) Gly482Ser polymorphisms (SNPs) have been associated with type 2 diabetes mellitus (T2DM) risk. We hypothesized that independent and interactive effects of the PPARG Pro12Ala and PPARGC1A Gly482Ser polymorphisms influence T2DM interme...

Full-text available
Several single nucleotide polymorphisms (SNPs) for type 2 diabetes mellitus (T2DM) risk have been identified by genome wide association studies (GWAS). The objective of the present study was to investigate the impact of these SNPs on T2DM intermediate phenotypes in order to clarify the physiological mechanisms through which they exert their effects...
Article
It has been suggested recently that molecules expressed both in the pancreas and hypothalamus, such as mu-opioid receptor 1 (OPRM1), could form an integrated brain-liver system, which may sense glucose levels and therefore contribute to the development of type 2 diabetes mellitus (T2DM). In the present study, we tested associations between OPRM1 ge...

Studies suggest that adiponectin (APM1) and its receptors 1 and 2 (AdipoR1 and AdipoR2) play an important role in the development of insulin resistance (IR). Our objective was to examine associations between APM1 (+45T>G, +276G>T and -3971A>G), AdipoR1 (-100G>T and -3882T>C) and AdipoR2 (-35361A>G and -1352G>A) genes single-nucleotide polymorphisms...
