This study evaluated the relationship between socio-demographic variables and leisure-time physical activity (LTPA). A baseline survey questionnaire was completed by 4,030 employees. LPTA was assessed as engagement in physical activities during the previous two weeks. The metabolic cost of LTPA was calculated based on frequency and amount of time participating in physical activities, assigning weekly metabolic equivalents (METs) to each activity. Odds ratios (OR) to express the relationship between socio-demographic factors and LTPA were estimated from multinomial regression models. The questions used to evaluate LTPA presented moderate reproducibility, with kappa correlation coefficients ranging from 0.45 to 0.88. Prevalence of LTPA was higher among men (52.2% men; 40.8% women). For both men and women, higher educational level and higher income were both associated with engaging in LPTA, this relationship being stronger for the highest tercile of METs as compared to physical inactivity. Men were more engaged in LTPA, and there was a strong association between LTPA and socio-demographic variables for both genders.
本研究评估了社会人口统计学变量与休闲时间体力活动（LTPA）之间的关系。4030名员工完成了一份基线调查问卷。LTPA被评估为前两周参与体育活动的情况。LTPA的代谢成本是根据参与体育活动的频率和时间来计算的，为每项活动分配每周代谢当量（METs）。从多项回归模型中估计了用于表达社会人口统计学因素与LTPA之间关系的优势比（OR）。用于评估LTPA的问题具有中等再现性，kappa相关系数在0.45至0.88之间。男性中LTPA的患病率较高（男性为52.2%；女性为40.8%）。对于男性和女性而言，较高的教育水平和较高的收入都与参与LTPA有关，与不进行体力活动相比，这种关系在METs最高三分位数时更强。男性更多地参与LTPA，并且LTPA与两性的社会人口统计学变量之间存在很强的关联。
