    摘要:

    目的 探讨中国中老年 (≥45岁)人群受教育水平与全因死亡风险的关系。方法 使用2011-2020年五次调查数据,收集受教育年限、年龄、性别、婚姻状况、户口类型、饮酒状况、吸烟状况、体力活动、日常生活活动能力受限情况、患慢性病情况、身体质量指数。据研究对象的生存状态分为存活组(n=8625)和全因死亡组(n=1735)。采用Cox比例风险回归模型分析中老年人受教育年限与全因死亡风险的关系,并进行分层分析。结果 调查10360名研究对象,其中男性4983名,女性5377名,受访者年龄M (QR) 为59(8)岁。总计随访88187人年(平均8.512人年),9年报告死亡共1735例,全因死亡率为19.674‰,受教育年限M (QR) 为5(8)年,生存时间M (QR) 为9(0)年。调节混杂因素后,受教育年限每升高1年,全因死亡风险降低2.60% [HR=0.974,95%CI(0.960~0.988)]。分层分析结果显示,在45~59岁的人群中,受教育年限每升高1年,全因死亡风险降低1.00% [HR=0.990,95%CI(0.959,1.021)];在60~74岁的人群和75岁以上的人群中,受教育年限每升高1年,全因死亡风险分别降低2.70% [HR=0.973,95%CI(0.948,0.999)]和3.50% [HR=0.965,95%CI(0.929,1.003)]。结论 中国中老年 (≥45岁)人群的受教育水平提高能降低全因死亡风险,应大力提倡老年教育。

    Abstract:

    Objective To explore the relationship between education level and the risk of all-cause mortality in the middle-aged and elderly (≥45 years old) population in China. Methods Using data from five surveys from 2011-2020, years of education, age, gender, marital status, type of household, alcohol consumption status, smoking status, physical activity, limited ability to perform activities of daily living (ADLs), chronic disease status, and body mass index were collected. According to the survival status,the study participants were divided into a survival group (n=8625) and an all-cause mortality group (n=1735). Cox proportional risk regression model was used to analyze the relationship between years of education and the risk of all-cause mortality in middle-aged and elderly people with stratified analysis. Results The survey was conducted on 10360 research subjects, including 4 983 males and 5 377 females, with an age M (QR) of 59 (8) years old. A total of 88 187 person years (average 8.512 person years) were followed up, and a total of 1735 deaths were reported over 9 years. The all-cause mortality rate was 19.674 ‰, with an education period M (QR) of 5 (8) years and a survival time M (QR) of 9 (0) years. After adjusting for confounding factors, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.60% [HR=0.974, 95% CI (0.960-0.988)]. The stratified analysis results showed that in the population aged 45-59, for every 1 year increase in education, the risk of all-cause mortality decreased by 1.00% [HR=0.990, 95% CI (0.959,1.021)]; In the population aged 60-74 and over 75, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.70% [HR=0.973, 95% CI (0.948, 0.999)] and 3.50% [HR=0.965, 95% CI (0.929, 1.003)], respectively. Conclusion Improving the education level of middle-aged and elderly people (≥ 45 years old) in China can reduce the risk of all-cause mortality, and elderly education should be vigorously promoted.
