Abstract

Background

Residents of rural, socioeconomically distressed counties,such as Appalachian Kentucky, experience disproportionately high cardiovascular disease (CVD) risk, compounded by sedentary behavior and poor self-reported physical health.

Objectives

This study investigates whether sedentary behavior and poor self-reported physical health serially mediate the relationship between years of residence in rural Appalachian Kentucky counties and CVD risk.

Methods

This secondary analysis included 309 adults residing in rural Appalachian counties. Sedentary behavior was measured as daily minutes in sedentary activity using an Actiwatch. Self-reported physical health was assessed using the Short-Form Health Survey-12, and CVD risk was measured using the Framingham risk score. Serial mediation analysis with two mediators was conducted using the PROCESS macro, controlling sociodemographic and lifestyle covariates.

Results

The participants’ mean age was 57.3 (±15) years, with an average residence duration of 42.7 (±22.2) years. Participants spent an average of 751.6 (±215.3) minutes per day in sedentary behavior, and the mean CVD risk was 15.3% (±10.4%). Years of residence were directly associated with increased CVD risk (direct effect = 0.168; 95% Boot CI [.117, 0.219]) and indirectly associated through sedentary behavior (indirect effect = 0.016; 95% Boot CI [.006, 0.039]). An additional indirect effect emerged through sedentary behavior leading to poorer self-reported physical health (indirect effect = 0.002; 95% Boot CI [.001, 0.004]).

Conclusion

These findings indicate that interventions targeting CVD risk reduction in rural socioeconomically distressed counties should include strategies to reduce sedentary behavior, which may improve self-reported physical health status and decrease CVD risk.

久坐行为和身体健康状况解释了在社会经济贫困县居住的年数与心血管疾病风险之间的关系。

背景：肯塔基州阿巴拉契亚地区等农村、社会经济贫困县的居民心血管疾病（CVD）风险过高，且久坐行为和自我报告的身体健康状况不佳。目的：本研究探讨在肯塔基州阿巴拉契亚县农村居住年限与心血管疾病风险之间，久坐行为和不良自我报告的身体健康状况是否在一定程度上起到中介作用。方法：这项二级分析包括居住在阿巴拉契亚县农村的309名成年人。久坐行为是用Actiwatch测量每天久坐活动的分钟数。自我报告的身体健康状况使用简短健康调查-12进行评估，心血管疾病风险使用Framingham风险评分进行测量。使用PROCESS宏观，控制社会人口统计学和生活方式协变量，对两个中介进行了串行中介分析。结果：参与者平均年龄为57.3（±15）岁，平均居住时间为42.7（±22.2）年。参与者平均每天静坐751.6分钟（±215.3分钟），平均心血管疾病风险为15.3%（±10.4%）。居住年限与心血管疾病风险增加直接相关（直接效应= 0.168；95%启动CI）。117, 0.219])，并与久坐行为间接相关(间接效应= 0.016;95% Boot CI[。006年,0.039])。另一个间接影响是久坐行为导致自我报告的身体健康状况较差（间接影响= 0.002;95% Boot CI）。001年,0.004])。结论：这些研究结果表明，针对农村社会经济困难县的CVD风险降低的干预措施应包括减少久坐行为的策略，这可能会改善自我报告的身体健康状况并降低CVD风险。

期刊介绍： Heart & Lung: The Journal of Cardiopulmonary and Acute Care, the official publication of The American Association of Heart Failure Nurses, presents original, peer-reviewed articles on techniques, advances, investigations, and observations related to the care of patients with acute and critical illness and patients with chronic cardiac or pulmonary disorders. The Journal''s acute care articles focus on the care of hospitalized patients, including those in the critical and acute care settings. Because most patients who are hospitalized in acute and critical care settings have chronic conditions, we are also interested in the chronically critically ill, the care of patients with chronic cardiopulmonary disorders, their rehabilitation, and disease prevention. The Journal''s heart failure articles focus on all aspects of the care of patients with this condition. Manuscripts that are relevant to populations across the human lifespan are welcome.
