To assess associations, both individually and in combination, between leisure-time physical activity and sedentary behavior, and cardiometabolic health.
This cross-sectional study included 13,931 civil servants participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Leisure-time physical activity was analyzed using the leisure-time domain of the long-form International Physical Activity Questionnaire, while questions related to cumulative sitting time and leisure-based screen time on a weekday and on one day on the weekend were used to establish sedentary behavior. Data analysis was performed using multivariate logistic regression.
Following adjustment for confounding variables, high levels of leisure-time physical activity and low levels of sedentary behavior were both associated with favorable cardiometabolic health markers in both genders. When these two factors were analyzed in conjunction, taking the combination of low levels of leisure-time physical activity and high levels of sedentary behavior as the reference, the inverse associations with cardiometabolic variables became even more significant.
High levels of leisure-time physical activity and low levels of sedentary behavior were both inversely associated with the cardiometabolic variables analyzed; however, the two variables when evaluated in conjunction appear to produce more consistent associations, particularly when sedentary behavior is evaluated according to leisure-based screen time.
评估休闲时间身体活动与久坐行为单独及联合与心脏代谢健康之间的关联。
这项横断面研究纳入了13931名参与巴西成人健康纵向研究（ELSA - Brasil）的公务员。使用长版国际体力活动问卷中的休闲时间领域来分析休闲时间身体活动，同时使用与工作日和周末一天的累计久坐时间及基于休闲的屏幕时间相关的问题来确定久坐行为。采用多因素逻辑回归进行数据分析。
在对混杂变量进行调整后，高水平的休闲时间身体活动和低水平的久坐行为均与两性良好的心脏代谢健康指标相关。当将这两个因素结合分析时，以低水平的休闲时间身体活动和高水平的久坐行为组合作为参照，与心脏代谢变量的反向关联变得更加显著。
高水平的休闲时间身体活动和低水平的久坐行为均与所分析的心脏代谢变量呈负相关；然而，当这两个变量联合评估时，似乎会产生更一致的关联，特别是当根据基于休闲的屏幕时间评估久坐行为时。
