目的了解河南省15~24岁青年人群超重、肥胖及中心性肥胖的流行情况,为其防治提供科学依据。方法按照多阶段随机抽样的方法选取调查对象,对河南省4 093名15~24岁青年人群的身高、体重及腰围进行测量并做描述性分析。结果河南省2012年15~24岁青年人群超重率、肥胖率、中心性肥胖率分别为13.10%、4.62%和16.69%。男性肥胖患病率(6.04%)高于女性(3.21%),差异有统计学意义(χ2=18.64,P<0.01)。城市男性超重率、肥胖率及中心性肥胖率均高于农村男性,城市女性中心性肥胖率低于农村女性,差异均有统计学意义(P<0.01)。学生超重率、肥胖率及中心性肥胖率均比其他职业低,差异均有统计学意义(P<0.01)。超重、肥胖及中心性肥胖随年龄和体质指数(BMI)的增长呈升高趋势(P<0.01);随着每周锻炼次数的增加,超重率、肥胖率和中心性肥胖率呈降低趋势(P<0.01);肥胖率及中心性肥胖率随经济收入的增加呈升高趋势(P<0.05)。结论河南省15~24岁青年人群以中心性肥胖流行为主,青年时期是超重、肥胖和中心性肥胖患病率升高的重要时期,在此阶段做好对青年人群的干预,对整个人群肥胖的预防有重要的影响。
Objective To understand the prevalence of overweight, obesity and central obesity among 15-24-year-old young people in Henan Province and provide a scientific basis for their prevention and treatment. Methods According to the method of multistage random sampling, the subjects were surveyed, and the height, weight and waist circumference of 4 093 young people aged 15-24 in Henan Province were measured and analyzed descriptively. Results The overweight rate, obesity rate and central obesity rate of young people aged 15 ~ 24 in Henan Province in 2012 were 13.10%, 4.62% and 16.69% respectively. The prevalence of obesity in males (6.04%) was higher than that in females (3.21%), with significant difference (χ2 = 18.64, P <0.01). The overweight rate, obesity rate and central obesity rate of urban males were higher than those of rural males. The central obesity rate of urban males was lower than that of rural females (P <0.01). Students overweight rate, obesity rate and central obesity rate were lower than other occupations, the differences were statistically significant (P <0.01). Overweight, obesity and central obesity increased with the increase of age and body mass index (BMI) (P <0.01). Overweight, obesity and central obesity decreased with the number of exercise per week P <0.01). The obesity rate and central obesity rate increased with the increase of economic income (P <0.05). Conclusion The prevalence of central obesity in young people aged 15 ~ 24 in Henan Province is predominant. In youth, the prevalence of overweight, obesity and central obesity is an important period. At this stage, young people are expected to intervene and the entire population Prevention of obesity has a significant impact.
