Abstract

Aim

This cohort study aimed to assess weight loss associated with new long-term care insurance (LTCI) certifications over a 9-year period, accounting for the competing risk of death.

Methods

We analyzed data from 3749 Japanese individuals aged ≥65 years in Kami Town, Hyogo Prefecture, Japan. Weight loss was assessed using the Kihon Checklist during the baseline survey. Data regarding LTCI certifications were collected until March 2022. Cox proportional hazards models were used to calculate adjusted hazard ratios (HRs) of 9-year LTCI certification because of weight loss, adjusted for confounding factors. To exclude the effect of competing risks, Fine-Gray regression was used to estimate subdistribution HRs. Subgroup analyses were carried out after the examination of potential interactions between subjective cognitive function, body mass index categories and weight loss.

Results

The incidence rate of new LTCI certifications was 5.16 per 100 person-years overall – broken down into 7.02 for those with weight loss and 4.97 for those without. The adjusted HR for weight loss to new LTCI certifications was 1.35 (95% CI 1.15–1.59). Considering mortality as a competing risk, the adjusted subdistribution HR was 1.37 (95% CI 1.16–1.61). Conversely, no interaction was observed between weight loss and subjective cognitive function or body mass index categories.

Conclusions

Excluding the effect of mortality, weight loss was identified as a risk factor for new LTCI certifications. However, no interaction was observed between weight loss and subjective cognitive function or body mass index categories. Geriatr Gerontol Int 2024; 24: 1320–1327.

自我报告的体重减轻与新的长期护理保险认证之间的关系：一项为期 9 年的日本老年人队列研究。

目的：这项队列研究旨在评估9年间与新的长期护理保险（LTCI）认证相关的体重减轻情况，同时考虑死亡的竞争风险：我们分析了日本兵库县上町 3749 名年龄≥65 岁的日本人的数据。在基线调查中使用 Kihon 检查表对体重减轻情况进行了评估。有关 LTCI 认证的数据收集至 2022 年 3 月。使用 Cox 比例危险模型计算因体重减轻而获得 9 年 LTCI 认证的调整危险比 (HRs)，并对混杂因素进行调整。为排除竞争风险的影响，采用 Fine-Gray 回归估算亚分布 HRs。在检查了主观认知功能、体重指数类别和体重减轻之间的潜在交互作用后，进行了分组分析：总体而言，新的长期护理保险认证发生率为每 100 人年 5.16 例，其中体重减轻者为 7.02 例，体重未减轻者为 4.97 例。体重减轻与新的 LTCI 证书的调整 HR 为 1.35（95% CI 1.15-1.59）。将死亡率视为竞争风险，调整后的子分布 HR 为 1.37（95% CI 1.16-1.61）。相反，在体重减轻与主观认知功能或体重指数类别之间没有观察到相互作用：排除死亡率的影响，体重减轻被认为是新的长期护理保险认证的一个风险因素。结论：排除死亡率的影响，体重减轻被确定为新的 LTCI 证书的风险因素，但在体重减轻与主观认知功能或体重指数类别之间未观察到交互作用。Geriatr Gerontol Int 2024; --：-----.
