Exposure to simultaneous sedentary behavior domains and sociodemographic factorsassociated in public servants

Abstract Exposure to sedentary behavior may contribute to health problems. This study aimed to estimate the prevalence of exposure to simultaneous sedentary behavior domains and verify associated sociodemographic characteristics among technical and administrative servers of a Brazilian university. This is a cross-sectional epidemiological study carried out with 623 technical and administrative servers. Sedentary behavior was identified through a questionnaire in the following domains: commuting (active / passive), sitting time at work, daily time spent watching television and computer use (≥3 hours / day). Sociodemographic variables were age, sex and educational level. The prevalence of servers that had one, two, three and four simultaneous sedentary behavior was 28.4%, 43.2%, 22.5% and 4.3%, respectively. Women were more likely to have three sedentary behavior simultaneously (OR = 1.61, CI 95% = 1.02, 2.56). Servers with 9-11 years of schooling were less exposed to two (OR = 0.27, CI 95% = 0.17, 0.44), three (OR = 0.39, CI 95% = 0.23, 0.66) and four (OR = 0.22, CI 95% = 0.07; 0.69) sedentary behavior simultaneously and those over 12 years of schooling were less likely of having two (OR = 0.22, CI 95% = 0.10; 0.49) and three (OR = 0.15, CI 95% = 0.05, 0.46) sedentary behavior simultaneously. More than half of servers have two sedentary behavior during the week. Having sedentary behavior in more than one domain simultaneously was associated with sex and educational level.

摘要 久坐行为（sedentary behavior）暴露可能引发健康问题。本研究旨在评估巴西某高校技术与行政人员同时暴露于多领域久坐行为的流行率，并验证其相关社会人口学特征。本研究为横断面流行病学研究（cross-sectional epidemiological study），共纳入623名技术与行政人员作为研究对象。通过问卷从以下领域评估久坐行为：通勤方式（主动/被动）、工作坐姿时长、每日看电视时长及电脑使用时长（≥3小时/天）。社会人口学变量包括年龄、性别与受教育程度。结果显示，同时存在1项、2项、3项及4项久坐行为的人员占比分别为28.4%、43.2%、22.5%及4.3%。女性同时存在3项久坐行为的风险更高（比值比（Odds Ratio，OR）=1.61，95%置信区间（Confidence Interval，CI）=1.02~2.56）。受教育年限为9~11年的人员，同时存在2项、3项及4项久坐行为的概率更低（OR分别为0.27、0.39、0.22，95%CI依次为0.17~0.44、0.23~0.66、0.07~0.69）；受教育年限超过12年的人员，同时存在2项及3项久坐行为的概率更低（OR分别为0.22、0.15，95%CI依次为0.10~0.49、0.05~0.46）。超过半数的研究对象在一周内存在2项久坐行为。同时存在多领域久坐行为与性别及受教育程度存在关联。
