OBJECTIVE
This study aimed to determine the independent and joint associations of sedentary time (ST) and physical activity (PA) with metabolic syndrome (MetS) and its components among Chinese adults.
METHODS
The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and 2015 China Health and Nutrition Surveys (CHNS). Four types of leisure ST and three types of PA self-reported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components.
RESULTS
For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio ( ) 1.3, 95% confidence interval ( ) 1.1-1.6, < 0.001; 1.4, 95% 1.2-1.8, < 0.001, respectively]. The MetS risk in the computer time > 7 hours/week (h/w) group was higher than that in the < 7 h/w group in ( 1.5, 95% 1.2-1.9). Higher levels of moderate-to-vigorous-intensity physical activity (MVPA) and total PA were associated with a lower MetS risk ( 0.7, 95% 0.6-0.9, < 0.001; 0.8, 95% 0.7-0.9, < 0.001, respectively). For the joint effects, compared with those reporting the lowest level of total leisure ST (< 14 h/w) and the most active tertile of MVPA (≥ 61.0 MET-h/w), participants reporting the most total leisure ST (≥ 35 h/w) and the lowest level of MVPA (0 MET-h/w) had the highest odds of MetS ( 2.0; 95% 1.4-2.7). Except for people reporting ST (14-21 h/w) within the most active tertile of MVPA, the associations in all other groups were significant. With the increase of TV time and decreased MVPA, the odds of MetS almost showed a curve acceleration.
CONCLUSIONS
MVPA and total PA have independent preventive effects, and sedentary behavior (mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.
目的
本研究旨在探讨中国成年人久坐时间（ST）和体力活动（PA）与代谢综合征（MetS）及其各组分的独立和联合关联。
方法
该研究分析了来自 2009 年和 2015 年中国健康与营养调查（CHNS）中≥18 岁的 4865 名成年人的数据。在基线时收集了四种类型的休闲 ST 和三种类型的自我报告的 PA。多变量逻辑回归用于确定 ST 和 PA 与 MetS 或其各组分发生几率的独立和联合关联。
结果
对于独立效应，看电视时间和总休闲 ST 水平较高与 MetS 风险增加相关[比值比（OR）分别为 1.3（95%置信区间（CI）为 1.1-1.6）， < 0.001；1.4（95%CI 为 1.2-1.8）， < 0.001]。每周电脑时间>7 小时（h/w）组的 MetS 风险高于每周<7 h/w 组（OR 为 1.5，95%CI 为 1.2-1.9）。中等到剧烈强度体力活动（MVPA）和总 PA 水平较高与 MetS 风险降低相关（OR 分别为 0.7（95%CI 为 0.6-0.9）， < 0.001；0.8（95%CI 为 0.7-0.9）， < 0.001）。对于联合效应，与报告最低总休闲 ST 水平（<14 h/w）和 MVPA 最高三分位（≥61.0 MET-h/w）的参与者相比，报告最高总休闲 ST 水平（≥35 h/w）和最低 MVPA 水平（0 MET-h/w）的参与者发生 MetS 的几率最高（OR 为 2.0；95%CI 为 1.4-2.7）。除了报告 MVPA 最高三分位（≥61.0 MET-h/w）内的 ST（14-21 h/w）的参与者外，所有其他组的关联均具有统计学意义。随着看电视时间的增加和 MVPA 的减少，MetS 的发生几率几乎呈现出曲线加速。
结论
MVPA 和总 PA 具有独立的预防作用，而久坐行为（主要是看电视）对 MetS 及其各组分具有不安全作用。为了降低中国成年人 MetS 的患病率，可能有必要加强 MVPA 的参与，并结合低强度体力活动代替以电视为基础的 ST 来增加总 PA。
