目的了解和分析贵州省成人超重、肥胖流行状况,为预防控制超重肥胖提供依据。方法采用多阶段整群随机抽样的方法,在贵州省9市(州)12个县(区)选取18岁及以上居民进行问卷调查,并测量身高和体重,计算体重指数(BMI),并对调查数据进行整理分析。结果全省共调查18岁及以上成人9 260人,超重率为24.6%,肥胖率为7.0%。男性和女性超重率分别为23.8%、25.3%,两者差异无统计学意义(P>0.05);男女肥胖率分别为5.9%、8.0%,差异有统计学意义(P<0.01)。城市居民超重率、肥胖率分别为28.5%、9.3%,均显著高于农村(23.3%、6.2%)(P<0.01)。各年龄组中,40岁~组超重率、肥胖率均为最高,分别为28.1%、9.1%。多因素Logistic回归分析显示,与肥胖相关的因素有年龄、地区、红肉摄入过量、性别、食用油炸食品。结论我省近1/3的人处于超重和肥胖状态,由之引发的慢性疾病将日益严重。因此,应针对重点人群积极采取综合措施预防和控制肥胖。
Objective To understand and analyze the prevalence of overweight and obesity among adults in Guizhou Province and provide evidence for preventing and controlling overweight and obesity. Methods A multistage cluster random sampling method was used to select the residents of 18 years old and above in 12 counties of 9 cities (prefectures) of Guizhou Province to conduct questionnaire survey, measure height and weight, calculate body mass index (BMI) Survey data to organize analysis. Results A total of 9 260 adults aged 18 and over were surveyed in the province. The overweight rate was 24.6% and the obesity rate was 7.0%. The overweight rates of males and females were 23.8% and 25.3%, respectively. There was no significant difference between the two groups (P> 0.05). The obesity rates of males and females were 5.9% and 8.0% respectively, with significant difference (P <0.01). The overweight rate and obesity rate of urban residents were 28.5% and 9.3%, respectively, which were significantly higher than those in rural areas (23.3% and 6.2%, P <0.01). In all age groups, the 40-year-old group had the highest rates of overweight and obesity, with 28.1% and 9.1% respectively. Multivariate logistic regression analysis showed that the factors related to obesity were age, area, overuse of red meat, sex, consumption of fried foods. Conclusion Nearly one in three people in our province are overweight and obese, and the chronic diseases caused by them will become increasingly serious. Therefore, we should take active measures to prevent and control obesity.
