摘　　要：目的探讨久坐行为(SB)、体力活动与腹型肥胖的相关性。方法回顾性纳入2017年10月至2019年2月在中南大学湘雅医院健康管理中心体检的18~65岁成年人,收集其生活方式问卷,根据是否具有久坐行为、中高强度体力活动(MVPA)是否达标将研究对象分成四组:SB≤6 h/d、MVPA≥150 min/w;SB≤6 h/d、MVPA<150 min/w;SB>6 h/d、MVPA≥150 min/w;SB>6 h/d、MVPA<150 min/w。计算各SB-MVPA组合中腹型肥胖的相对危险度。结果研究共纳入5789例受检者,腹型肥胖者达28.52%。腹型肥胖人群与正常对照相比平均年龄较大,文化程度较低,已婚者较多,吸烟比例较高,水果摄入较少,睡眠时间较短,每日总坐立时间及职业性坐立时间较长(均P<0.05)。SB与MVPA联合分析结果显示,在调整了可能的混杂因素之后,SB>6 h/d、MVPA<150 min/w组发生腹型肥胖的风险增高(OR=1.379,95%CI:1.111~1.711)。职业性久坐行为[SB(W)]与MVPA联合分析结果显示,在调整了可能的混杂因素之后,SB(W)≤6 h/d、MVPA<150 min/w组(OR=1.270,95%CI:1.047~1.541)和SB(W)>6 h/d、MVPA<150 min/w组(OR=1.256,95%CI:1.043~1.513)发生腹型肥胖的风险增高。结论体力活动不足及久坐行为可能增加成年人腹型肥胖风险。对职业人群而言,充足的MVPA能有效降低职业性久坐带来的腹型肥胖风险。Objective To explore the correlation between sedentary behavior(SB),physical activity and abdominal obesity.Methods Adults aged 18 to 65 years who underwent physical examination in the Health Management Center of Xiangya Hospital,Central South University from October 2017 to February 2019 were retrospectively included and their lifestyle questionnaires were collected.The subjects were divided into four groups,according to different combinations of sitting time and the time spent on moderate to vigorous intensity physical activity(MVPA):SB≤6 h/d,MVPA≥150 min/w;SB≤6 h/d,MVPA<150 min/w;SB>6 h/d,MVPA≥150 min/w;SB>6 h/d,MVPA<150 min/w.The relative risk of abdominal obesity for each SB-MVPA combination was calculated.Results A total of 5,789 physical examination subjects were included in the study,with an abdominal obesity rate of 28.52%.People with abdominal obesity were older,had a lower level of education and a higher marriage rate,smoked more,consumed less fruit,slept less,and sat more(all P<0.05)compared with normal control.After adjusting for possible confounding factors,the risk of abdominal obesity was increased in the SB>6 h/d,MVPA<150 min/w group(OR=1.379,95%CI:1.111-1.711).The results of the combined analysis of the occupational SB(W)and the MVPA showed an increased risk of abdominal obesity in the SB(W)≤6 h/d,MVPA<150 min/w group(OR=1.270,95%CI:1.047-1.541),as well as in the SB(W)>6 h/d,MVPA<150 min/w group(OR=1.256,95%CI:1.043-1.513),after adjusting for possible confounding factors.Conclusion Lack of physical activity,as well as sedentary behavior are associated with an increased risk of abdominal obesity.For the working population,sufficient MVPA can effectively decrease the risk of abdominal obesity caused by occupational sedentary behavior.
