Identifying appropriate pre-pregnancy body mass index classification to improve pregnancy outcomes in women of childbearing age in Beijing, China: a retrospective cohort study.

This study explored the appropriate classification of pre-pregnancy body mass index (BMI) in women of childbearing age in Beijing, China. METHODS AND STUDY DESIGN: Women with singleton pregnancies at more than 28 gestational weeks were retrospectively reviewed. Based on the pre-pregnancy BMI (kg/m2), these patients were divided into 7 groups: =18.5-22.9,>=23-23.9,>=24-24.9,>=25-27.9,>=28-29.9, and>=30. Pregnancy adverse outcomes, including gestational hypertension with or without preeclampsia, gestational diabetes mellitus, initial cesarean section, postpartum hemorrhage, macrosomia, large-for-gestational age infant and so on were recorded. Binary logistic regression analysis was used to calculate the uncorrected and corrected odds ratios and 95% confidence intervals, with the>=18.5-22.9 group serving as a reference. RESULTS: A total of 11,136 pregnant women were analyzed. Incidences of above mentioned six adverse outcomes were greater in women with higher pre-pregnancy BMI. The risks of the abovementioned six adverse outcomes were increased significantly among the>=23-23.9,>=24-24.9,>=25-27.9 groups and substantially higher in the>=28-29.9,>=30 groups after correction. =18.5-22.9 kg/m2, with the cutoff value for overweight status being>=23.0 kg/m2 and the cutoff value for obesity being>=28.0 kg/m2.

Authors: D'Anna R, Santamaria A, Alibrandi A, Corrado F, DI Benedetto A, Facchinetti F Abstract Gestational Diabetes Mellitus (GDM) is one of the most frequent complications of pregnancy and is characterized by a carbohydrate intolerance which is diagnosed with the oral glucose tolerance test. The prevalence of GDM in our population is about 12%, but risk factors like a previous GDM, ethnicity, a parent with diabetes mellitus type 2 and maternal overweight may increase its occurrence. Complications of GDM are a pre-term birth (before 37 wk gestation), macrosomia (birth weight ≥4 kg) and gestational hypertension....

Objectives: Either maternal gestational diabetes mellitus (GDM) or hypertensive disorder of pregnancy (HDP) is associated with an increased risk of obesity in the offspring. However, their joint associations with obesity in offspring remain unclear. We investigated the joint associations of maternal GDM and HDP with childhood overweight in offspring.Methods: We performed a large study in 1967 mother-child pairs. Maternal GDM was diagnosed according to the 1999 World Health Organization (WHO) criteria. HDP was defined as self-reported doctor-diagnosed hypertension or treatment of hypertension (including gestational hyperten...

ConclusionsHigher inflammatory potential of the diet was positively associated with higher total cholesterol levels in women with SLE. These findings suggest that the inflammatory potential of a person’s diet may play a role in lipid profiles in this population. Future intervention studies are needed to build on these results and explore the effect of anti-inflammatory diets on health outcomes in individuals with SLE.

AbstractBackgroundGestational diabetes mellitus (GDM) is a major public health problem and threat to maternal and child health in Africa. No prior review has been conducted in Africa using the updated GDM diagnostic criteria. Therefore, this review aimed to estimate the pooled prevalence and determinants of GDM in Africa by using current international diagnostic criteria.MethodsA systematic review and meta-analysis was conducted by comprehensive search of the published studies in Africa. Electronic databases (PubMed, Scopus, Cochrane Library, EMBASE, Google Scholar, CINAHL, Web of Science, Science direct and African Journa...

ConclusionsThere is neither concerted effort to diagnose GDM, nor systematic records of screening and postpartum follow-up. The gap in diabetology knowledge and practice calls for re-training of antenatal healthcare professionals. GDM screening checklist needs to be established and positive results entered into GDM registers for proper management during and after delivery.

AbstractPurpose of ReviewTo present current data on the coexistence of attention deficit hyperactivity disorder (ADHD) and the metabolic syndrome and type 2 diabetes mellitus in adults and children and to discuss possible mechanisms.Recent FindingsEmerging data suggest that risk factors for obesity and insulin resistance such as diabetes during pregnancy and intrauterine growth failure may also have a role in the development of ADHD. Furthermore, ADHD and obesity share lifestyle factors, such as abnormal eating patterns, binge eating, and a sedentary lifestyle. ADHD is a risk factor for components of the metabolic syndrome...

This study aimed to evaluate the impact of selected pregnancy pathologies statistically depending on overweight/obesity and excessive maternal weight gain during pregnancy on women who gave birth in the years 2013–2015 at the Second Department of Gynecology and Obstetrics at the University Hospital in Bratislava, Slovakia. In a retrospective study, we analyzed data gathered from the sample, which consisted of 7122 women. Our results suggest a statistically significant, higher risk for the groups of women with overweight and obesity and gestational hypertension (adjusted odds ratio (AOR) = 15.3; 95% CI 9.0&min...

We thank Dr Senthilkumaran and colleagues for their interest in our work and for sharing their experience with myocardial infarction (MI) during pregnancy in southern India. In the series of 12 cases they reported, MI occurred in the third trimester or in the first week of the puerperium. All women were of advanced maternal age or had at least one cardiovascular risk factor, including obesity, hypertension, or diabetes mellitus. These data differ from our analysis of the large US National Inpatient Sample, in which 61% of women had no known preceding risk factors for MI.

Conclusion: Periodontal disease is significantly and positively correlated with increased risk of hypertension in Chinese population, and exact mechanisms of this association should be explored in future. Introduction Periodontal disease is a complex polymicrobial inflammation, including gingivitis and periodontitis. According to the 2015 Global Burden of Disease (GBD) study, the prevalence of severe chronic periodontitis in 2015 has reached 616 million (Kassebaum et al., 2017). In China, the periodontal disease standardized DALYs rate has risen from 24.7 in 1990 to 25.7 in 2013 according to the data from 2013 GBD ...

This study aimed to compare the effect of high-intensity interval training (HIIT) with moderate-intensity continuous training (MCT) on endothelial function, oxidative stress and clinical fitness in patients with type 1 diabetes. Thirty-six type 1 diabetic patients (mean age 23.5 ± 6 years) were randomized into 3 groups: HIIT, MCT, and a non-exercising group (CON). Exercise was performed in a stationary cycle ergometers during 40 min, 3 times/week, for 8 weeks at 50–85% maximal heart rate (HRmax) in HIIT and 50% HRmax in MCT. Endothelial function was measured by flow-mediated dilation (FMD) [endothelium-depende...
