目的分析彭州市居民的肥胖流行特征。方法利用中英合作项目“中国慢性病前瞻性研究(CKB)”彭州点基线调查数据,以体重指数(BMI)、腰围和体脂百分比(BF%)三个指标来评价调查对象的肥胖患病率。结果本次研究共调查55687例,男性21314人,女性34373人,男性肥胖率为5.70%,中心性肥胖率为23.93%,体脂百分比超标率为55.77%,女性肥胖率为9.86%,中心性肥胖率为37.68%,体脂百分比超标率为59.92%;随年龄增长肥胖率、中心性肥胖率、体脂百分比超标率均先升高后下降(男性:x~2=51.22,P<0.001;x~2=82.94,P<0.001;x~2=609.16,P<0.001;女性:x~2=201.33,P<0.001;x~2=900.02,P<0.001;x~2=402.97,P<0.001),经常吸烟者肥胖率、中心性肥胖率、体脂百分比超标率低于其他吸烟情况组(男性:x~2=133.14,P<0.001;x~2=200.25,P<0.001;x~2=187.62,P<0.001;女性:x~2=26.40,P<0.001;x~2=88.28,P<0.001;x~2=186.07,P<0.001),休息静坐时间越长,调查对象肥胖率、中心性肥胖率、体脂百分比超标率越高(男性:x~2=75.11,P<0.001;x~2=245.99,P<0.001;x~2=160.63,P<0.001;女性:x~2=31.55,P<0.001;x~2=45.04,P<0.001;x~2=173.60,P<0.001)。结论彭州市成人肥胖患病率较高,为了预防与控制肥胖流行,应提倡健康的生活方式,适当增加体力活动,合理膳食,尤其是在更年期妇女及高收入人群中开展肥胖的宣传和控制。
Objective To analyze the prevalence of obesity in Pengzhou residents. Methods According to the Sino-British cooperation project “CKB” and “Pengzhou Point Baseline Survey Data”, the obese patients in the survey were evaluated by BMI, BF% and body mass percentage (BF%) Disease rate. Results 55687 cases were investigated, including 21314 males and 34373 females. The obesity rate of males was 5.70%, the rate of central obesity was 23.93%, the percentage of body fat exceeded 55.77%, and the rate of obesity was 9.86%. The centrality Obesity rate was 37.68% and body fat percentage exceeded the rate of 59.92%. With age, obesity rate, central obesity rate and body fat percentage exceeded the first increased and then decreased (male: x ~ 2 = 51.22, P <0.001; x ~ 2 = 82.94, P <0.001; x ~ 2 = 609.16, P <0.001; women: x ~ 2 = 201.33, P <0.001; 0.001). The rates of obesity, central obesity and body fat percentage in regular smokers were lower than those in other smoking groups (male: x ~ 2 = 133.14, P <0.001; 2 = 187.62, P <0.001; women: x2 = 26.40, P <0.001; x2 = 88.28, P <0.001; x2 = 186.07, P <0.001). The longer the rest and sitting, the obesity (Male: x ~ 2 = 75.11, P <0.001; x ~ 2 = 245.99, P <0.001; x ~ 2 = 160.63, P <0.001; women: x ~ 2 = 31.55, P <0.001; x ~ 2 = 45.04, P <0.001; x ~ 2 = 173.60, P <0.001). Conclusion The prevalence of obesity in Pengzhou is relatively high. In order to prevent and control obesity epidemic, we should advocate a healthy life style, appropriately increase physical activity and reasonable diet, especially in menopausal women and high-income groups.
