辽宁省成年居民超重与肥胖现状及其相关因素分析

Analysis on the Epidemiological Characteristics and Relative Factors of Adult Overweight and Obesity in Liaoning Province

目的了解辽宁省成年居民超重与肥胖的流行特点及相关因素,为制定相关的防治措施提供科学依据。方法采用多阶段分层整群随机抽样方法,抽取辽宁省城市、农村的7个市(区、县)共8120人,用询问调查法获得18岁以上居民个人基本情况和相关因素,测量身高、体重。结果辽宁省成年人超重率为33.9%,肥胖率为13.7%。超重、肥胖率城市均高于农村,差别均有统计学意义(超重为x^2=147.24,P<0.01;肥胖为x^2=47.39,P<0.01);女性均高于男性,差别均有统计学意义(超重为x^2=27.48,P<0.01;肥胖为x^2=36.66,P<0.01),且超重、肥胖率均随年龄的增加而升高,超重率在40～49岁、肥胖率在60～69岁年龄组达到最高。经多因素分析,职业性体力活动、吸烟、年龄为超重、肥胖的共同影响因素,OR(95%CI)分别为0.85(0.80～0.90),0.67(0.60～0.75),1.15(1.12～1.19);0.72(0.64～0.82),0.69(0.53～0.91),1.11(1.04～1.18)。结论辽宁省成年居民超重、肥胖患病现状和趋势不容乐观,超重、肥胖率均高于全国2002年平均水平,超重人群基数大。多种危险因素与超重、肥胖相关,应尽快采取干预措施。

Objective To describe the epidemiological characteristics and relative factors of adults with overweight and obesity in Liaoning province. Methods With multi-stage randomized cluster sampling, 8 120 cases were selected from the 540 families in seven urban and suburb districts of Liaoning province, data of overweight and obesity history and social- economic status for residents aged 18 yrs and over were investigated by face-to-face interview, weight and height of these subjects were measured. Result the overweight rate was 33.9%, the obesity rate was 13.7%. The prevalent rates of overweight and obesity were increased with the age and it was higher in city than in rural and in female than in male （all P〈0.0i）. The overweight rate in 40-49 yrs and the obesity rate in 60-69 yrs reached their peak values. The relative risk factors were screened by Logistic regression analysis. The major relative risk factors for overweight and obesity were income （OR =1.18, 95%CI： 1.13-1.23 for overweight; OR=1.08, 95%CI： 1.00-1.16 for obesity）, physical activity （0.85, 0.80-0.90; 0.72, 0.64- 0.82）, smoke （0.67, 0.60-0.75; 0.69, 0.53～0.91） and age （1.15, 1.12～1.19; 1.11, 1.04-1.18）. Conclusions The results indicated it allowed no optimism for the status and developing trend of adult overweight and obesity in Liaoning Province, the rates of adult overweight and obesity were higher than those of all over the country. Many factors were related to adult overweight and obesity. Intervention should be taken to change this situation as soon as possible.
