Increased body weight was associated with an increased risk of ovarian cancer; in particular, severe obesity demonstrated a stronger risk effect. No statistically significant association was observed in the postmenopausal period, but was in the premenopausal period.

BackgroundThe prevalence of abdominal obesity is increasing dramatically worldwide. This study aimed to estimate the current prevalence of abdominal obesity from the 2011 China Health and Nutrition Survey (CHNS) and compare the data with other countries.MethodsWaist circumference (WC) of 12,326 Chinese adults (aged 20 years or older) from the 2011 CHNS were analyzed by age group and region. Abdominal obesity was defined as a WC ≥90 cm for men and WC ≥80 cm for women based on World Health Organization (WHO) recommendations for Asians.ResultsIn 2011, the age-adjusted mean WC was 85.9 cm (95% confidence interval [CI], 85.6–86.2 cm) for men and 80.7 cm (95% CI, 80.4–80.9 cm) for women. Based on the WHO recommendations, the age-adjusted prevalence of abdominal obesity was 44.0% (95% CI, 43.1%–44.8%) overall, 35.3% (95% CI, 34.1%–36.6%) in men, and 51.7% (95% CI, 50.5%–52.9%) in women. Moreover, the age-adjusted prevalence was 44.0% (95% CI, 42.7%–45.2%) in rural populations, 42.5% (95% CI, 40.7%–44.2%) in urban populations, and 45.2% (95% CI, 43.5%–46.9%) in megacity populations. The prevalence in China (35.3% for men and 51.7% for women) was lower than in Japan (50.8% for men) and the United States (43.5% for men and 64.7% for women). Similar results were observed when applying the criteria suggested by the Working Group on Obesity in China.ConclusionsIn 2011, the age-adjusted prevalence of abdominal obesity in China was 35.3% in men and 51.7% in women.

Background and Aim: Several epidemiological studies have reported the association between obesity and multiple sclerosis (MS). Methods: A literature search of the observational studies, published as original articles in English before December 2015, was performed using electronic databases. Results: Five observational studies were included, of which 3 were case-control studies and 2 were cohort studies. The pooled relative risk (RR) for overweight and obesity during childhood and adolescence compared with normal weight (body mass index = 18.5-24.9 kg/m²) was 1.44 (95% CI 1.22-1.70) and 2.01 (95% CI 1.63-2.48), respectively. In subgroup analyses, we found that excess body weight during childhood and adolescence increased the risk of MS in the female group (overweight: pooled RR = 1.62, 95% CI 1.35-1.94; obesity: pooled RR = 2.25, 95% CI 1.77-2.85), but not in the male group (overweight: pooled RR = 1.19, 95% CI 0.91-1.55; obesity: pooled RR = 1.22, 95% CI 0.79-1.90). Conclusions: Excess body weight during childhood and adolescence was associated with an increased risk of MS; severe obesity demonstrated a stronger risk. A statistically significant association was found in the female group, but not in the male group.

Both the prevalence of hypertension and the percentage of current use of antihypertensive medication significantly increased from 1991 to 2011. Currently, about one-fifth of Chinese adults are hypertensive; however, only 17.5% of hypertension is controlled.
