We examined the prevalence of psychological outcomes (i.e., symptoms of depression and anxiety) by age and age-varying associations between physical activity and psychological outcomes among rural cancer survivors. Participants (N = 219; ages 22-93) completed sociodemographic, psychological, and physical activity questionnaires. Time-varying effect models estimated the prevalence of psychological outcomes and assessed associations between physical activity and psychological outcomes as a flexible function of age. Depression and anxiety symptoms decreased with age among cancer survivors aged 22-40 years and were relatively stable across age among those > 40 years. Positive associations between vigorous physical activity and psychological outcomes in those aged 22-40 years were identified. In those > 70-80 years, there were negative associations between vigorous physical activity and psychological outcomes. Results suggest there is variation across age in the associations between physical activity and psychological outcomes among rural survivors. Future research should further explore these age-varying relationships to identify important intervention targets.

农村癌症幸存者的体育活动与心理结果之间的年龄相关性。

我们通过年龄和在农村癌症幸存者中体育活动与心理结果之间的年龄变化关联来研究心理结果（即抑郁症和焦虑症）的患病率。参与者（N = 219； 22-93岁）填写了社会人口统计学，心理和体育活动调查表。随时间变化的效应模型估计了心理结局的发生率，并评估了身体活动与心理结局之间作为年龄的灵活函数的关联。在22至40岁的癌症幸存者中，抑郁和焦虑症状随年龄的增长而降低，而在40岁以上的癌症幸存者中，抑郁和焦虑症状的年龄相对稳定。在22-40岁年龄段的人群中，积极的体育锻炼与心理结局之间存在正相关关系。在那些70-80岁的年龄段，剧烈的体育活动与心理结果之间存在负相关关系。结果表明，农村幸存者的体育活动与心理结果之间的关联因年龄而异。未来的研究应进一步探索这些随年龄变化的关系，以确定重要的干预目标。
