目标：体力活动和经济压力是疾病的独立且相反的预测因素。这项研究探讨了体力活动是否改变了财务压力与空腹血糖受损之间的当前和未来关系。方法：参与者是年轻人冠状动脉风险发展研究的一部分，这是一项检查疾病发展的前瞻性研究。参与者于 1985 年至 1986 年招募，并随访了 20 年。结果指标是第 7 年和第 20 年的空腹血糖 (FG) 水平。第 7 年和第 20 年分别有 3991 名和 3500 名参与者获得了 FG。结果：财务压力对血糖水平升高的影响因体力活动水平而异，如第 7 年 (p = .02) 和第 20 年 (p = .04) 协方差分析的显着交互作用项所示。计划对比表明，经济紧张但不运动的参与者的 FG 水平与经济紧张但积极活动的参与者以及所有经济压力较低的参与者之间存在显着差异。具体来说，在不太活跃的参与者中，经济紧张的参与者的调整后平均 PG 水平较高（第 7 年为 2.27 mg/dL，第 20 年为 5.86 mg/dL）。在活跃的参与者中，第 7 年时这些差异为 -1.78 mg/dL，第 20 年时可以忽略不计。结论：对于经济紧张的成年人来说，体力活动与 13 年后发生 FG 受损的风险降低相关。越来越多的文献表明体力活动有可能缓解与压力相关的疾病过程。
Objectives: Physical activity and financial strain are independent, and opposite, predictors of disease. This study examines whether physical activity modifies the concurrent and prospective relation between financial strain and impaired fasting glucose. Methods: Participants were part of the Coronary Artery Risk Development in Young Adults study, a prospective study examining the development of disease. Participants were recruited in 1985 to 1986 and followed up for 20 years. The outcome measures were fasting glucose (FG) levels at Years 7 and 20. FG was available at Years 7 and 20 from 3991 and 3500 participants, respectively. Results: The effects of financial strain on elevated glucose levels differed by physical activity levels as indicated by the significant interaction terms for the analyses of covariance at Year 7 (p = .02) and Year 20 (p = .04). Planned contrast comparisons demonstrated that FG levels in financially strained participants who were physically inactive were significantly different from financially strained participants who were active, and all participants with low financial strain. Specifically, in less active participants, the adjusted mean PG levels were higher in financially strained participants (2.27 mg/dL at Year 7 and 5.86 mg/dL at Year 20). In active participants, these differences were -1.78 mg/dL at Year 7 and negligible at Year 20. Conclusions: In adults burdened by financial strain, physical activity is associated with a reduced risk of developing impaired FG up to 13 years later. This adds to a growing literature showing the potential of physical activity to moderate stress-related disease processes.
