2013年安徽省成年人身体活动和静态行为状况分析

目的 了解安徽省成年人日常身体活动和静态行为现状。方法 采用多阶段整群随机抽样方法，以面对面询问方式收集调查对象的慢性病相关危险因素、业余身体活动和静态行为时间等相关信息，并对样本进行复杂抽样设计加权和事后分层权重调整后，估算相关指标。结果 2013年安徽省成年人从不锻炼率为88.69%（95%CI:85.83%~91.55%），经常锻炼率为8.03%（95%CI:5.32%~10.74%），身体活动不足率为18.04%（95%CI:11.40%~24.68%）。随着教育水平的提高，从不锻炼率下降，而经常锻炼率和身体活动不足比例均升高（P0.05）。城镇、高教育水平和从事脑力劳动人群的身体活动不足比例较高（P0.05）。人均每日总静态时间为4.33（95%CI:4.19~4.47）h，其中看电视、使用电脑和手机时间分别为105.30（95%CI:97.03~113.58）min、30.85（95%CI:23.64~38.07）min和22.01（95%CI:15.82~28.20）min。随着年龄和教育水平的增加，静态行为时间分别递减和递增，屏幕时间同样如此（P0.01）。结论 安徽省成年人业余锻炼水平较低，身体活动不足普遍存在，业余静态行为时间较长，尤其要关注青年、城镇和高教育水平人群的屏幕时间情况。

Prevalence of physical exercise and sedentary behavior in adults in Anhui,2013

Objective To understand the prevalence of leisure-time physical excise and sedentary behavior in adults in Anhui.Methods A face-to-face questionnaire survey was conducted among local adults selected through multi-stage stratified random sampling to collect the information about chronic noncommunicable disease related risk factors and the prevalence of leisure-time physical excise and sedentary behavior.The related index were estimated after complex sampling design weight and post stratification adjustment.Results The percentage of local residents who never took excise,took regular excise and took insufficient excise was 88.69％ (95％ CI:85.83％-91.55％),8.03％ (95％ CI:5.32％-10.74％),and 18.04％ (95 ％ CI:11.40％-24.68％),respectively.People with higher education level showed lower never excise rate,and higher regular excise and insufficient excise rates compared with those with lower education level (P ＜ 0.05).The insufficient excise rate was higher in those in urban area,with higher education level and being engaged in mental work than those in rural area,with low education level and being engaged in manual labor (P ＜ 0.05).The local adults spent 4.33 hours per day on sedentary behavior (95％ CI:4.19-4.47),including 105.30 minutes for watching TV (95％ CI:97.03-113.58),30.85 minutes for using computer (95％ CI:23.64-38.07),and 22.01 minutes for using mobile phone (95％ CI:15.82-28.20).The sedentary behavior time increased with age and decreased with education level,the time spent on watching screen was similar (P ＜ 0.01).Conclusion The physical activity level was low and lack of physical exercise was common in adults in Anhui.Close attention should be paid to those with young age,living in urban area and with higher education level because they spent much time on watching screen.
