To examine the association of sedentary behavior (SB) with metabolic syndrome (MetS) in adults, as well as to identify the impact of physical inactivity and economic condition on such association.
This is a cross-sectional study.
This study was conducted in the city of Bauru, São Paulo State, Brazil (n = 970). Television (TV) viewing and physical activity (PA) were assessed by questionnaire. MetS was assessed via medical records. Descriptive statistics and binary logistic regression were used in data analyses.
Participants with moderate TV viewing were associated with MetS when compared with low TV viewing group, even after adjustments for age, sex, economic status, smoking, and PA (odds ratio [OR] = 1.49 [95% confidence interval {CI}: 1.01-2.20]). The fully adjusted model showed an association between high exposure to TV viewing with MetS (OR = 1.77 [95%CI: 1.11-2.82]). The combination of physical inactivity and high TV viewing boosted the likelihood of having MetS (OR = 1.89 [95%CI: 1.08-3.29]).
The results of the present study suggest that moderate and high TV viewing time is associated with the presence of MetS, mainly in insufficiently active adults and those living in lower economic condition.
探讨成年人久坐行为（SB）与代谢综合征（MetS）的相关性，并确定身体活动不足和经济状况对这种相关性的影响。
这是一项横断面研究。
本研究在巴西圣保罗州包鲁市（n=970）进行。通过问卷调查评估电视（TV）观看和身体活动（PA）。通过病历评估 MetS。数据分析采用描述性统计和二元逻辑回归。
与低 TV 观看组相比，中度 TV 观看者与 MetS 相关，即使在调整了年龄、性别、经济状况、吸烟和 PA 后也是如此（比值比[OR] = 1.49 [95%置信区间 {CI}：1.01-2.20]）。完全调整后的模型显示，高 TV 观看与 MetS 之间存在关联（OR = 1.77 [95%CI：1.11-2.82]）。身体活动不足和高 TV 观看的组合增加了患有 MetS 的可能性（OR = 1.89 [95%CI：1.08-3.29]）。
本研究结果表明，中等和高时长的 TV 观看与 MetS 的发生有关，主要发生在活动不足的成年人和经济状况较差的人群中。
