Gestational Diabetes: Physical Activity Before Pregnancy and Its Influence on the Cardiovascular System.

ABSTRACT: Objectives: Gestational diabetes mellitus (GDM) is a common complication in pregnancy, affecting around 14% of all pregnancies each year. It will likely further increase, as obesity becomes more prevalent. The impact of GDM on cardiovascular changes in pregnant women and her child is still unclear. The aim of the study was to measure the effects of physical activity before pregnancy on the cardiovascular system in patients with GDM in pregnancy. Methods: Two hundred and six pregnant women were included in this observational study. All participants were recruited at the tertiary level teaching University Hospital "Klinikum rechts der Isar" between 28 and 32 weeks gestation. Questionnaires dealing with pre-pregnancy daily and physical activity (PA) were evaluated. The cardiovascular status of the mothers included measurements of the intima-media thickness (IMT) of the carotid arteries. PA level was performed with a standardized 6-min-walking-test. Results: Ninety-nine women with GDM with a mean age of 33.84 (± 4.7) years were examined. One hundred seven healthy pregnant women aged 32.6 (± 4.2) years served as controls. The mean weight in the study group was 73.0 (± 20.3) kg and 61.7 (± 9.5) kg in the control group. Based on the higher weight in the study group, the Body Mass Index (BMI) was also significantly higher than in the control group (26.3 ± 7.1 vs. 21.6 ± 3; p < 0.001). The frequency of PA was significantly higher in the control group (p < 0.001). The objective fitness level was worse in pregnant women with GDM compared to healthy controls (472 vs. 523 m, p < 0.001). PA before and during pregnancy was less performed in the study group (86 vs. 64.5%, p = 0.002; 69 vs. 45.7%, p = 0.003). Women who were physically inactive before pregnancy had a 3-times higher risk to develop GDM compared to active women (OR = 2.67). The IMT was significantly thicker in the study group (0.48 ± 0.042 mm vs. 0.45 ± 0.042) mm; p = 0.006). Conclusion: Physical activity before pregnancy and a lower initial weight reduces the risk of developing GDM and cardiovascular risk factors in pregnancy. The development of prevention programs is certainly necessary.

Project description:The aim of this study was to examine associations of body composition (fat mass index, % fat mass, fat-free mass index, body mass index) and physical fitness (cardiorespiratory fitness and handgrip strength) with gestational diabetes and cardiovascular health in early pregnancy. This cross-sectional study utilized baseline data (n = 303) collected in early pregnancy from the HealthyMoms trial. Body composition was measured using air-displacement plethysmography, cardiorespiratory fitness was assessed by means of the 6-min walk test and handgrip strength using a dynamometer. Logistic regression was used to estimate odds ratios (ORs) for gestational diabetes as well as high (defined as 1 SD above the mean) blood pressure, homeostatic model assessment for insulin resistance (HOMA-IR), and metabolic syndrome score (MetS score) per 1 SD increase in body composition and fitness variables. Fat mass index, % fat mass and body mass index were all strongly associated with gestational diabetes (ORs: 1.72-2.14, P ≤ 0.003), HOMA-IR (ORs: 3.01-3.80, P < 0.001), blood pressure (ORs: 1.81-2.05, P < 0.001) and MetS score (ORs: 3.29-3.71, P < 0.001). Associations with fat-free mass index were considerably weaker (ORs: 1.26-1.82, P = 0.001-0.15) and were strongly attenuated after adjustments for fat mass index (ORs: 0.88-1.54, P = 0.039-0.68). Finally, greater cardiorespiratory fitness was associated with lower risk of high HOMA-IR and MetS score (ORs: 0.57-0.63, P ≤ 0.004) although these associations were attenuated when accounting for fat mass index (ORs: 1.08-1.11, P ≥ 0.61). In conclusion, accurately measured fat mass index or % fat mass were strongly associated with gestational diabetes risk and markers of cardiovascular health although associations were not stronger than the corresponding ones for body mass index. Fat-free mass index had only weak associations with gestational diabetes and cardiovascular health which support that the focus during clinical care would be on excess fat mass and not fat-free mass.
