上海市18～69岁居民对推荐身体活动量的知晓现状

Awareness to recommended levels of physical activity among residents aged 18-69 years in Shanghai

目的：了解上海市居民对推荐身体活动量的知晓情况，为进一步促进市民参加身体活动提供依据。方法在全市18个区采用分层随机抽样方法，被抽取8458名18～69岁的调查对象通过面对面的访谈完成问卷，采用中国疾病预防控制中心开展全民健康生活方式行动评估而设计的统一问卷。率的显著性采用χ2检验，影响因素采用 Logistic 回归分析。结果在调查对象中，知晓“生活、出行加运动，每天至少运动6000步是推荐身体活动量”的7544人（89．2％）；知晓“每周至少150 min 中等强度有氧运动”是推荐身体活动量的3875人（45．8％）。Logistic 回归分析显示，性别（OR ＝1．184，95％ CI：1．030～1．361）、年龄（OR ＝1．136，95％CI：1．020～1．264）、文化程度（OR ＝1．143，95％CI：1．046～1．249）、家庭年收入（OR ＝1．047，95％CI：1．009～1．086）和居住地（OR ＝0．796，95％CI：0．687～0．922）是知晓前者的影响因素，而文化程度（OR ＝1．241，95％CI：1．174～1．313）和居住地（OR ＝1．473，95％CI：1．345～1．614）则是后者的影响因素。结论相对“每周至少150 min 中等强度有氧运动”，上海居民对生活、出行加运动，每天至少运动6000步”的身体活动推荐量有较高的认识度。调整年龄和性别后，文化程度和居住地对上述两个推荐量的知晓水平产生影响。

Objective To understand status of awareness to recommended level of physical activity and provide evi-dences for further promoting participation of physical activity among residents in Shanghai.Methods Stratified random sam-pling method was used to enroll samples in all 18 districts in Shanghai.A total of 8548 participants aged 18 -69 years were re-cruited and questionnaire survey was carried out by face-to-face interview.The unified questionnaire of evaluating national ac-tion for health lifestyle designed by China National Center for Disease Control and Prevention was used.The significances of rates were tested by Chi-square and associations with determinations were analyzed by logistic regression model.Results A-mong the residents in Shanghai,7544 （89.2%）and 3875 （45.8%）participants knew the recommended levels of “at least 6000 steps of physical activity of daily life,travel,and exercising everyday”and “at least 150 minutes of moderate intensity aerobic exercise every week”.Analysis results of logistic regression showed that gender （OR =1.184,95%CI：1.030 -1.361）,age （OR =1.136,95% CI：1.020 -1.264）,education level （OR =1.143,95% CI：1.046 -1.249）,annual household income （OR =1.047,95% CI：1.009 -1.086）and area of residence （OR =0.796,95% CI：0.697 -0.922） for the former and education level （OR =1.241,95% CI：1.174 -1.313）and area of residence （OR =1.473,95% CI：1.345 -1.614）were influencing factors to awareness.Conclusion There was higher proportion of awareness to recommended level of “at least 6000 steps of physical activity of daily life,travel,and exercising everyday”compared with “at least 150 minutes of moderate intensity aerobic exercise every week”among Shanghai residents.After adjustment for age and gender,ed-ucation level and area of residence can influence awareness level of both recommended levels.
