The purpose of this study was to assess the relationship between economic security and self-rated health for elderly Japanese residents living alone.
A secondary analysis of a cross-sectional study.
N City, H. Prefecture, Japan.
Survey questionnaires were distributed to 2,985 elderly residents living alone, aged ≥70 years, of which, 1,939 (65.0%) were returned and treated as valid responses.
The survey included questions about gender, age, number of years spent in N City, self-rated health, economic security, number of years spent living alone, reason for living alone, life satisfaction, cooking frequency, frequency of seeing a doctor, long-term care service usage, as well as whether they enjoyed their lives, participated in social organizations.
Of the respondents, 1,563 (80.6%) reported that they were economically secure, and 376 (19.4%) responded that they were insecure. The odds ratio predicting poor self-rated health for the economically insecure participants was significantly high (odds ratio: 3.19, 95%, Confidence Interval (CI): 2.53-4.02, and P < 0.001). Similarly, the adjusted odds ratio for poor self-rated health was significantly high for the economically insecure participants in multivariate analyses controlling for factors such as age, gender, cooking frequency, and social participation (adjusted odds ratio: 2.21, 95%, CI: 1.70-2.88, and P < 0.001). Furthermore, a similar trend was observed in stratified analyses based on gender and age groups.
Economic security predicted self-rated health independently of confounders, including social participation and cooking frequency, among the elderly Japanese living alone in communities.
本研究旨在评估独居日本老年人的经济保障与自感健康之间的关系。
一项横断面研究的二次分析。
日本 H 县 N 市。
向 2985 名年龄≥70 岁、独居的老年人发放调查问卷，其中 1939 名（65.0%）返回并视为有效应答。
调查内容包括性别、年龄、在 N 市居住年限、自感健康、经济保障、独居年限、独居原因、生活满意度、烹饪频率、就医频率、长期护理服务使用情况以及对生活的享受程度和参与社会组织情况。
在应答者中，1563 名（80.6%）报告经济有保障，376 名（19.4%）报告经济无保障。经济无保障者自感健康状况不佳的优势比显著较高（优势比：3.19，95%置信区间：2.53-4.02，P<0.001）。同样，在多变量分析中，控制年龄、性别、烹饪频率和社会参与等因素后，经济无保障者自感健康状况不佳的调整优势比也显著较高（调整优势比：2.21，95%置信区间：1.70-2.88，P<0.001）。此外，基于性别和年龄组的分层分析也观察到了类似的趋势。
经济保障可独立于社会参与和烹饪频率等混杂因素预测独居日本老年人的自感健康。
