  • 摘要:
    目的 探讨江苏省苏州市吴中区30~79岁居民体力活动水平和休闲静坐时间与衰弱的关系,为当地居民衰弱的预防控制提供参考依据。
    方法 收集中国慢性病前瞻性研究(CKB)苏州市吴中区项目点2004年11月— 2008年1月基线调查中53 269名30~79岁居民的相关数据,应用无序多分类logistic回归模型分析体力活动水平和休闲静坐时间与衰弱前期、衰弱期之间的关系。
    结果 苏州市吴中区53 269名30~79岁居民中,23 096人(43.36%)处于衰弱前期状态,1 227人(2.30%)处于衰弱期状态;体力活动水平为 < 12.73 MET-h/d 13 315人(25.00%),12.73~23.19 MET-h/d 13 319人(25.00%),23.20~37.29 MET-h/d 13 311人(24.99%), ≥ 37.30 MET-h/d 13 324人(25.01%);休闲静坐时间为0~2 h/d 24 631人(46.23%),3~4 h/d 20 028人(37.61%),5~6 h/d 5 764人(10.82%), 7 h/d 2 846人(5.34%)。在控制了性别、年龄、文化程度、婚姻状况、家庭年均收入、吸烟情况、饮酒情况、新鲜蔬菜摄入频率、新鲜水果摄入频率和红肉摄入频率等混杂因素后,无序多分类logistic回归分析结果显示,体力活动水平为12.73~23.19 MET-h/d、23.20~37.29 MET-h/d、 ≥ 37.30 MET-h/d的苏州市吴中区30~79岁居民处于衰弱前期的风险分别为 < 12.73 MET-h/d居民的0.76倍(OR = 0.76,95%CI = 0.72~0.80)、0.67倍(OR = 0.67,95%CI = 0.63~0.71)和0.66倍(OR = 0.66,95%CI = 0.62~0.69),处于衰弱期的风险分别为0.50倍(OR = 0.50,95%CI = 0.43~0.59)、0.35倍(OR = 0.35,95%CI = 0.29~0.43)和0.29倍(OR = 0.29,95%CI = 0.23~0.36);休闲静坐时间为3~4 h/d、5~6 h/d和 ≥ 7 h/d的苏州市吴中区30~79岁居民处于衰弱前期的风险分别为0~2 h/d居民的1.10倍(OR = 1.10,95%CI = 1.06~1.14)、1.33倍(OR = 1.33,95%CI = 1.25~1.41)和1.61倍(OR = 1.61,95%CI = 1.48~1.76),休闲静坐时间为5~6 h/d和 ≥ 7 h/d的苏州市吴中区30~79岁居民处于衰弱期的风险分别为0~2 h/d居民的1.57倍(OR = 1.57,95%CI = 1.30~1.89)和2.65倍(OR = 2.65,95%CI = 2.17~3.24)。
    结论 苏州市吴中区30~79岁居民体力活动水平与衰弱呈负相关,而休闲静坐时间与衰弱则呈正相关。

     

    Abstract:
    Objective To investigate the relationship between physical activity level, leisure sedentary time, and frailty among residents aged 30 – 79 years in Wuzhong district, Suzhou city, Jiangsu province, and to provide a reference for the prevention and control of frailty among local residents.
    Methods Data were collected from 53 269 residents aged 30 – 79 years in Wuzhong district, Suzhou city, who participated in the baseline survey of the China Kadoorie Biobank (CKB) from November 2004 to January 2008. An unordered multinomial logistic regression model was used to analyze the relationship between physical activity level, leisure sedentary time, and pre-frailty and frailty.
    Results Of the 53 269 residents aged 30 – 79 years in Wuzhong district, Suzhou city, 23 096 (43.36%) were pre-frail and 1 227 (2.30%) were frail. The physical activity levels were categorized as follows: < 12.73 MET-h/d (13,315 participants, 25.00%), 12.73 – 23.19 MET-h/d (13 319 participants, 25.00%), 23.20 – 37.29 MET-h/d (13 311 participants, 24.99%), and ≥ 37.30 MET-h/d (13 324 participants, 25.01%). Leisure sedentary time was categorized as follows: 0 – 2 h/d (24 631 participants, 46.23%), 3 – 4 h/d (20 028 participants, 37.61%), 5 – 6 h/d (5 764 participants, 10.82%), and ≥ 7 h/d (2 846 participants, 5.34%). After adjusting for confounding factors such as sex, age, education level, marital status, annual household income, smoking status, alcohol consumption, frequency of fresh vegetable intake, frequency of fresh fruit intake, and frequency of red meat intake, the results of unordered multinomial logistic regression analysis showed that compared with residents with a physical activity level of < 12.73 MET-h/d, the risk of pre-frailty was 0.76 times lower (OR = 0.76, 95%CI = 0.72 – 0.80), 0.67 times lower (OR = 0.67, 95%CI = 0.63 – 0.71), and 0.66 times lower (OR = 0.66, 95%CI = 0.62 – 0.69) for those with physical activity levels of 12.73 – 23.19 MET-h/d, 23.20 – 37.29 MET-h/d, and ≥ 37.30 MET-h/d, respectively. The risk of frailty was 0.50 times lower (OR = 0.50, 95%CI = 0.43 – 0.59), 0.35 times lower (OR = 0.35, 95%CI = 0.29 – 0.43), and 0.29 times lower (OR = 0.29, 95%CI = 0.23 – 0.36), respectively. Compared with residents with a leisure sedentary time of 0 – 2 h/d, the risk of pre-frailty was 1.10 times higher (OR = 1.10, 95%CI = 1.06 – 1.14), 1.33 times higher (OR = 1.33, 95%CI = 1.25 – 1.41), and 1.61 times higher (OR = 1.61, 95%CI = 1.48 – 1.76) for those with leisure sedentary times of 3 – 4 h/d, 5 – 6 h/d, and ≥ 7 h/d, respectively. The risk of frailty was 1.57 times higher (OR = 1.57, 95%CI = 1.30 – 1.89) and 2.65 times higher (OR = 2.65, 95%CI = 2.17 – 3.24) for those with leisure sedentary times of 5 – 6 h/d and ≥ 7 h/d, respectively.
    Conclusions Physical activity level was negatively correlated with frailty, while leisure sedentary time was positively correlated with frailty among residents aged 30 – 79 years in Wuzhong district, Suzhou city.
