摘要:


文题释义:
慢性病共病:同一个体同时存在2种或2种以上需要长期医疗照护的慢性健康问题。
CHARLS:即中国健康与养老追踪调查,旨在收集一套代表中国45岁及以上中老年人家庭和个人的高质量微观数据,用以分析中国人口老龄化问题,推动老龄化问题的跨学科研究。

背景:已有研究表明,夜间睡眠时长与正常人群心脑血管疾病的发生存在紧密关联。然而,在慢性病共病人群这一特定群体中,夜间睡眠时长所发挥的作用仍有待深入探究。
目的:深入剖析中国老年慢性病共病人群夜间睡眠时长与心脑血管相关疾病之间的内在联系。同时,精准探究体质量指数在这一关联中是否具有潜在的中介作用。
方法:选取 2011年与2020年中国健康与养老追踪调查(CHARLS)中年龄≥45岁的中老年人群作为研究对象,运用Logistic回归模型细致分析夜间睡眠时长对心脑血管疾病(涵盖心脏病、脑卒中、情感及精神类疾病、记忆相关疾病)可能产生的潜在影响。此外,通过中介分析方法,评估体质量指数在夜间睡眠时长与心脑血管事件之间的作用。
结果与结论:①年龄、体质量指数与慢性病共病人群新发心脑血管病均呈现出显著的关联性(P < 0.05);而性别、婚姻状况、受教育程度以及地区等因素在不同睡眠时长组间存在极为显著差异(P < 0.001)。在慢性病共病人群中,女性、结婚、受教育程度为小学及以下、生活在城镇等因素,构成了新发心脑血管病的危险因素。②进一步分析表明,当睡眠时间达到6.9 h时,发生心脑血管病的风险显著降低(P < 0.05);随着夜间睡眠时长每上升1个四分位数间距,新发心脑血管事件的风险呈现出逐步降低的趋势,差异有显著性意义(P < 0.05)。③此外,夜间睡眠时长对心脑血管相关疾病的影响,大部分是通过体质量指数发挥中介作用来实现的,且这种中介效应极为显著(P < 0.001)。同时,夜间睡眠时长对心脑血管病还存在间接的负向效应,且该效应在统计学上同样显著(P < 0.05)。综上所述,合理的睡眠量能够显著降低中老年慢性病共病人群心脑血管疾病的发病风险,体质量指数发挥着至关重要的部分中介作用。

Abstract: BACKGROUND: Existing studies have clearly demonstrated a strong association between nocturnal sleep duration and the incidence of cardiovascular and cerebrovascular diseases in the general population. However, in the specific group of patients with chronic comorbidities, the role of nocturnal sleep duration warrants further in-depth exploration.
OBJECTIVE: To comprehensively analyze the intricate relationship between nocturnal sleep duration and cardiovascular and cerebrovascular diseases among elderly Chinese patients with chronic comorbidities and to precisely investigate whether body mass index plays a potential mediating role in this relationship.
METHODS: This study enrolled middle-aged and elderly individuals aged 45 years and above from the China Health and Retirement Longitudinal Study (CHARLS) in 2011 and 2020 as the research subjects. The Logistic regression model was employed to meticulously analyze the potential impact of nocturnal sleep duration on cardiovascular and cerebrovascular diseases (including heart diseases, strokes, emotional and mental disorders, and memory-related diseases). Furthermore, a mediation analysis was conducted to accurately evaluate the role of body mass index in the relationship between nocturnal sleep duration and cardiovascular and cerebrovascular events.
RESULTS AND CONCLUSION: (1) There was a significant association between age, body mass index, and the incidence of new-onset cardiovascular and cerebrovascular diseases among patients with chronic comorbidities (all P < 0.05). Moreover, there were highly significant differences in factors such as sex, marital status, educational level, and region among different sleep duration groups (all P < 0.001). Specifically, in individuals with chronic comorbidities, being female, married, having an educational level of primary school or below, and living in urban areas were all identified as risk factors for new-onset cardiovascular and cerebrovascular diseases. (2) Further analyses indicated that when the sleep duration reached 6.9 hours, the risk of developing cardiovascular and cerebrovascular diseases was significantly reduced (P < 0.05). Additionally, as the nocturnal sleep duration increased by one interquartile range, the risk of new-onset cardiovascular and cerebrovascular events gradually decreased, with a statistically significant difference (P < 0.05). (3) Moreover, the impact of nocturnal sleep duration on cardiovascular and cerebrovascular diseases was mainly mediated by body mass index, and this mediating effect was highly significant (P < 0.001). Meanwhile, nocturnal sleep duration also had a direct negative effect on cardiovascular and cerebrovascular diseases, and this effect was also statistically significant (P < 0.05). In conclusion, an appropriate amount of sleep can significantly reduce the incidence of cardiovascular and cerebrovascular diseases in this population, and body mass index plays a crucial partial mediating role.
