本研究的目的是评估中国南方超重/肥胖、腹型肥胖的患病率以及肥胖相关的危险因素。2013年11月至2014年8月，在中国江西省进行了一项15，364名15岁及以上参与者的横断面调查，使用问卷和身体测量。体格测量包括身高、体重、腰围、体脂百分比和内脏脂肪指数。采用多因素Logistic回归分析超重/肥胖和腹型肥胖的危险因素。超重率为25.8%（男性25.9%，女性25.7%），肥胖率为7.9%（男性8.4%，女性7.6%）。腹型肥胖患病率为10.2%（男性8.6%，女性11.3%）。城市居民超重/肥胖患病率为37.1%，农村居民为30.2%，差异有显著性（P < 0.001）。城市居民腹型肥胖患病率为11.6%，显著高于农村居民的8.7%（P < 0.001）。在体重过轻/体重指数（BMI）正常的参与者中，1.3%仍然有腹部肥胖，16.1%有高BFP，1.0%有高VAI。此外，在肥胖参与者中，9.7%的WC低/正常，0.8%的BFP正常，15.9%的VAI正常。偏相关分析表明，VAI与BMI、VAI与WC、BMI与WC的相关系数分别为0.700、0.666、0.721。多因素Logistic回归分析表明，女性、高BFP和高VAI与超重/肥胖和腹部肥胖的风险增加显著相关。此外，生活在城市地区和年龄较大与超重/肥胖有关。结果表明，肥胖和腹型肥胖在我国南方地区普遍存在，且存在性别和年龄差异。此外，WC、BMI和VAI之间存在非常高的显著正相关。然而，需要进一步的研究来探索哪些体脂指标可以作为间接反映心脏代谢风险的最佳标志物。
The purpose of this study is to assess the prevalence of overweight/obesity, abdominal obesity and obesity-related risk factors in southern China. A cross-sectional survey of 15,364 participants aged 15 years and older was conducted from November 2013 to August 2014 in Jiangxi Province, China, using questionnaire forms and physical measurements. The physical measurements included body height, weight, waist circumference (WC), body fat percentage (BFP) and visceral adipose index (VAI). Multivariate logistic regression analysis was performed to evaluate the risk factors for overweight/obesity and abdominal obesity. The prevalence of overweight was 25.8% (25.9% in males and 25.7% in females), while that of obesity was 7.9% (8.4% in males and 7.6% in females). The prevalence of abdominal obesity was 10.2% (8.6% in males and 11.3% in females). The prevalence of overweight/obesity was 37.1% in urban residents and 30.2% in rural residents, and this difference was significant (P < 0.001). Urban residents had a significantly higher prevalence of abdominal obesity than rural residents (11.6% vs 8.7%, P < 0.001). Among the participants with an underweight/normal body mass index (BMI), 1.3% still had abdominal obesity, 16.1% had a high BFP and 1.0% had a high VAI. Moreover, among obese participants, 9.7% had a low /normal WC, 0.8% had a normal BFP and 15.9% had a normal VAI. Meanwhile, the partial correlation analysis indicated that the correlation coefficients between VAI and BMI, VAI and WC, and BMI and WC were 0.700, 0.666, and 0.721, respectively. A multivariate logistic regression analysis indicated that being female and having a high BFP and a high VAI were significantly associated with an increased risk of overweight/obesity and abdominal obesity. In addition, living in an urban area and older age correlated with overweight/obesity. This study revealed that obesity and abdominal obesity, which differed by gender and age, are epidemic in southern China. Moreover, there was a very high, significant, positive correlation between WC, BMI and VAI. However, further studies are needed to explore which indicator of body fat could be used as the best marker to indirectly reflect cardiometabolic risk.
