Chronic and lifestyle-related diseases and social status were reported to be associated with long-term care (LTC). The social factors should be treated as social sub-groups of which characteristics show social profiles. However, few previous studies considered that. The present study aimed to investigate the associations between LTC and chronic and lifestyle-related diseases, and whether the associations were modified by the social sub-groups in the community-dwelling elderly.
A cross-sectional study was conducted among 1004 community-dwelling participants aged 80 and 90. LTC was used as the outcome. Chronic and lifestyle-related diseases (i.e., stroke, heart disease, joint pain, osteoporosis, lung disease, cancer, hypertension, dyslipidemia, and diabetes) were used as the predictors. Education, household income, residential area, and support environment were analyzed by latent class analysis (LCA) to derive social profiles. We obtained odds ratios (ORs) of LTC from those diseases and tested interactions between those diseases and the social profiles by logistic regression analyses.
The participants were categorized into two sub-groups of social factors (n = 675 and 329) by LCA. Logistic regression analyses showed ORs (95% CI) of LTC were 4.69 (2.49, 8.71) from stroke, 2.22 (1.46, 3.38) from joint pain, 1.99 (1.22, 3.25) from osteoporosis, and 2.05 (1.22, 3.40) from cancer adjusting for the social sub-groups. There were no significant interactions between the social subgroups and those diseases in relation to LTC except for osteoporosis.
The associations between LTC and chronic and lifestyle-related diseases were significant with adjusting for the social sub-groups, and not modified by that except osteoporosis.
慢性疾病和与生活方式相关的疾病以及社会地位与长期护理（LTC）有关。社会因素应被视为具有社会特征的社会亚组。然而，以前很少有研究考虑到这一点。本研究旨在调查社区居住的老年人中 LTC 与慢性疾病和与生活方式相关的疾病之间的关系，以及这些关联是否因社会亚组而改变。
对 1004 名 80 岁和 90 岁的社区居民进行了横断面研究。将 LTC 作为结果。慢性疾病和与生活方式相关的疾病（即中风、心脏病、关节痛、骨质疏松症、肺部疾病、癌症、高血压、血脂异常和糖尿病）被用作预测因子。通过潜在类别分析（LCA）分析教育、家庭收入、居住区域和支持环境，以得出社会特征。我们从这些疾病中获得了 LTC 的优势比（OR），并通过逻辑回归分析测试了这些疾病与社会特征之间的相互作用。
通过 LCA 将参与者分为社会因素的两个亚组（n=675 和 329）。逻辑回归分析显示，调整社会亚组后，中风的 LTC 的 OR（95%CI）为 4.69（2.49，8.71），关节痛为 2.22（1.46，3.38），骨质疏松症为 1.99（1.22，3.25），癌症为 2.05（1.22，3.40）。除骨质疏松症外，社会亚组与这些疾病与 LTC 之间没有显著的相互作用。
调整社会亚组后，LTC 与慢性疾病和与生活方式相关的疾病之间存在显著关联，但除骨质疏松症外，这种关联不受其影响。
