There is increasing evidence for the relationship between physical activity (PA), sedentary behaviour and mental health. Limited data exists on sex-specific associations. We aimed to identify associations between PA dose and domain and television time with psychological distress, including sex-stratified models.
A total of 22,176 adults from the Melbourne Collaborative Cohort Study follow-up 2 cohort (2003-2007) participated in this cross-sectional study. Occupational, household, transport, leisure PA, hours watching television and psychological distress were assessed. Restricted cubic splines were used to examine the relationships between PA domains, television viewing time and psychological distress.
The relationships between PA and psychological distress were non-linear (p < 0.05) and differed by PA domain. There were dose-dependent, inverse associations between distress with transport (B[95% CI] = -0.39[-0.49, -0.30]) and leisure PA (B[95% CI] = -0.35[-0.46, -0.25]). The effect estimates for transport and leisure PA with distress were larger for women. For household domain, a U-shaped curve with an elongated tail was seen. Median PA was associated with lower distress compared with lower quantities (B[95% CI] = -0.12[-0.22, -0.03]); however, this association was not evident with increasing household PA. There were no clear associations between occupational PA and distress. Higher television viewing was associated with higher distress (B[95% CI] = 0.16[0.02, 0.30]).
Increasing PA and reducing television viewing may contribute to reduced psychological distress, particularly in women. Future interventions should incorporate leisure and transport PA and decrease television viewing to assess the impact on mental health.
越来越多的证据表明，身体活动（PA）、久坐行为与心理健康之间存在关联。关于特定性别相关性的数据有限。我们旨在确定 PA 剂量和领域与电视时间与心理困扰之间的关联，包括按性别分层的模型。
共 22176 名来自墨尔本合作队列研究后续 2 队列（2003-2007 年）的成年人参与了这项横断面研究。评估了职业、家务、交通、休闲 PA、看电视时间和心理困扰。受限立方样条用于检验 PA 领域、看电视时间与心理困扰之间的关系。
PA 与心理困扰之间的关系是非线性的（p<0.05），且因 PA 领域而异。与交通（B[95%CI]=-0.39[-0.49，-0.30]）和休闲 PA（B[95%CI]=-0.35[-0.46，-0.25]）呈剂量依赖性负相关。对于女性，交通和休闲 PA 与心理困扰的效应估计值更大。对于家务领域，呈现出一种 U 形曲线，且长尾。与较低的运动量相比，中等运动量（B[95%CI]=-0.12[-0.22，-0.03]）与较低的心理困扰相关联；然而，随着家务活动量的增加，这种关联并不明显。职业 PA 与心理困扰之间没有明显的关联。看电视时间增加与心理困扰增加相关（B[95%CI]=0.16[0.02，0.30]）。
增加 PA 和减少看电视时间可能有助于降低心理困扰，尤其是对女性而言。未来的干预措施应包括休闲和交通 PA，并减少看电视时间，以评估对心理健康的影响。
