摘　　要：目的了解山西省老年人向心性肥胖现状,其运动步数与向心性肥胖的关系。方法于2022年对山西省常住居民开展慢性病及其危险因素调查,采用多阶段分层随机抽样抽取4710名常住老年居民(≥60岁)作为调查对象,使用χ^(2)检验分析向心性肥胖的影响因素。应用logistic回归模型分析运动步数与向心性肥胖之间的关系。结果老年人的肥胖率和向心性肥胖率分别为17.7%和41.3%,每日运动步数是向心性肥胖的影响因素(P=0.004)。通过对不同年龄组的分析,在排除混杂因素影响后,以运动步数≤3000步组作为对照,60~<70岁年龄组中,3000~<6000步组、6000~<10000步组和≥10000步组老年人的向心性肥胖患病率分别降低了32.7%、43.8%和33.9%(OR=0.673,95%CI:0.545~0.832,P<0.001;OR=0.562,95%CI:0.449~0.703,P<0.001;OR=0.661,95%CI:0.497~0.878,P=0.004)。70~<80岁年龄组中,≥10000步组老年人向心性肥胖患病率降低了44.6%(OR=0.554,95%CI:0.343~0.895,P<0.001),其他组别差异均无统计学意义(均P>0.05)。结论运动步数对降低不同年龄阶段老年人向心性肥胖率的影响各不相同,应针对性地采取干预措施:鼓励低龄老年人(60~<70岁)每天保持6000~<10000步的运动量,中龄(70~<80岁)和高龄(≥80岁)老年人应该在自身身体状况能够承受运动的强度和频率下合理控制运动步数,以提高自身的身体健康水平并预防向心性肥胖。Objective To investigate the current status of central obesity among elderly residents in Shanxi Province and explore the association between number of exercise steps and central obesity.Methods In 2022,a survey on chronic diseases and their risk factors was conducted among permanent residents of Shanxi Province using a multi-stage stratified random sampling method.A total of 4710 resident elderly residents(60 years old and above)were selected as the respondents.Theχ^(2) test was used to analyze the influencing factors of central obesity and logistic regression model to analyze the relationship between number of exercise steps and central obesity.Results The results showed that the prevalence rates of obesity and central obesity were 17.7%and 41.3%,respectively.Number of exercise steps was identified as a impact factor affecting central obesity(P=0.004).Through the analysis of different age groups,after excluding the influence of confounding factors,the exercise step number≤3000 group was taken as the comparison group.The prevalence of central obesity decreased by 32.7%,43.8%and 33.9%in the 60-<70 age group in the 3000-6000 steps group,6000-10000 steps group,and 10000 steps and above group,respectively(OR=0.673,95%CI:0.545-0.832,P<0.001;OR=0.562,95%CI:0.449-0.703,P<0.001;OR=0.661,95%CI:0.497-0.878,P=0.004).In the 70-<80 age group,the prevalence of central obesity decreased by 44.6%in the above 10000 steps group(OR=0.554,95%CI:0.343-0.895,P<0.001),while there was no statistical significance in other groups(P>0.05).Conclusions The impact of number of exercise steps on reducing the prevalence of central obesity among elderly people varies by age groups.Targeted intervention measures should be taken.Encourage younger elderly individuals(aged 60-<70)to maintain a daily number of exercise steps between 6000 to 10000.For middle-aged(aged 70-<80)and older elderly individuals(aged 80 and above),the number of exercise steps should be reasonably controlled under the intensity and frequency of exercise that their physical
