This study explores relations between occupational and leisure-time physical activity (OPA, LTPA) and sedentary behavior (OSB, LTSB) and several health outcomes.
A total 114 full-time workers had their body composition, waist circumference, height, weight, resting heart rate, and resting blood pressure measured. ActivPal monitor measured physical activity behaviors. Stress, mood, and pain were measured with ecological momentary assessment. General linear models were used to examine the relationship between high and low OPA, LTPA, OSB, and LTSB with each health outcome while controlling for covariates.
The high LTPA group had lower body mass index (BMI) (P = 0.04) and better mood (P = 0.007) than the low LTPA group. The high LTSB group had higher systolic blood pressure (P = 0.001), higher diastolic blood pressure (P = 0.01), higher BMI (P = 0.027), higher body fat percentage (P = 0.003), higher waist circumference (P = 0.01), and worse mood (P = 0.032) than the low LTSB group. No differences were found between OPA and OSB groups.
These findings suggest there may be differential relations between PA and SB accumulated during leisure versus occupational time.
本研究探讨了职业和休闲体力活动（OPA、LTPA）与久坐行为（OSB、LTSB）与多种健康结果之间的关系。
共有 114 名全职工作人员接受了身体成分、腰围、身高、体重、静息心率和静息血压测量。ActivPal 监测器测量了身体活动行为。使用生态瞬时评估测量了压力、情绪和疼痛。一般线性模型用于检查高和低 OPA、LTPA、OSB 和 LTSB 与每个健康结果之间的关系，同时控制协变量。
高 LTPA 组的体重指数（BMI）较低（P=0.04），情绪较好（P=0.007）。高 LTSB 组的收缩压较高（P=0.001），舒张压较高（P=0.01），BMI 较高（P=0.027），体脂肪百分比较高（P=0.003），腰围较高（P=0.01），情绪较差（P=0.032）。OPA 和 OSB 组之间没有差异。
这些发现表明，在休闲时间和职业时间积累的 PA 和 SB 之间可能存在不同的关系。
