This study evaluates the longitudinal relation between self-reported physical activity and health related work limitations (also known as presenteeism) among employees from a public university system. A retrospective longitudinal study design was used to examine research aims. Data were from self-reported health assessments collected from employees at a large University System in Texas during the 2013-2015 plan years (n=6515).Work limitations were measured using the self-report 8-item work limitations questionnaire. Latent growth curve models were used to test whether: 1) baseline physical activity was associated with baseline work limitations; 2) changes in physical activity were related to changes in work limitations; and 3) baseline physical activity predicted changes in work limitations. Models were adjusted for demographic and health-related variables. The final adjusted growth curve model demonstrated excellent fit. Results revealed baseline physical activity was inversely associated with baseline work limitations (β=-0.12, p<0.001). In addition, changes in physical activity were related to changes in work limitations (β=-0.33, p=0.02). However, no relation was found between baseline physical activity and changes in work limitations (β=-0.06, p=0.42). Results provide evidence that increasing physical activity among employees leads to decreases in health-related work limitations. Therefore, promoting physical activity among employee populations can help prevent and reduce presenteeism.
本研究评估了自报体力活动与公共大学系统员工健康相关工作限制（也称为出勤主义）之间的纵向关系。采用回顾性纵向研究设计来检验研究目的。数据来自德克萨斯州一个大型大学系统在 2013-2015 年计划年度内从员工那里收集的自我报告健康评估（n=6515）。工作限制使用自我报告的 8 项工作限制问卷进行测量。潜增长曲线模型用于检验以下三个假设：1）基线体力活动与基线工作限制有关；2）体力活动的变化与工作限制的变化有关；3）基线体力活动预测工作限制的变化。模型调整了人口统计学和健康相关变量。最终调整后的增长曲线模型显示出良好的拟合度。结果表明，基线体力活动与基线工作限制呈负相关（β=-0.12，p<0.001）。此外，体力活动的变化与工作限制的变化有关（β=-0.33，p=0.02）。然而，在基线体力活动和工作限制的变化之间没有发现关系（β=-0.06，p=0.42）。结果提供了证据表明，增加员工的体力活动会导致与健康相关的工作限制减少。因此，在员工群体中促进体力活动可以帮助预防和减少出勤主义。
