We aimed to investigate the association between subjective memory complaints and higher-level functional capacity in either people with long-term care needs or those who require help to maintain functional capacity.
We conducted a cross-sectional study among participants aged 60 years or older. We measured subjective memory complaints, higher-level functional capacity, and depressive symptoms, and then estimated odds ratios (ORs) by multiple logistic analysis. Subjective memory complaints were used as the predictor variable, higher-level functional capacity as the outcome variable, and age, depressive symptoms, medical history of diabetes and hypertension, frequency of going out, falling within a year, and body mass index as possible confounders. We assessed higher-level functional capacity using the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence score ≤5 as a cut-off (which is associated with higher one-year mortality rates).
We conducted analyses using 501 people aged 60 years or older. Among women, subjective memory complaints were associated with impaired higher-level functional capacity after adjustment for age and depressive symptoms (OR=3.36; 95% confidence interval [CI], 1.59-7.08). Among the men, subjective memory complaints were not significantly associated with impaired higher-level functional capacity after adjustment for age and depressive symptoms (OR=1.91; 95% CI, 0.88-4.12).
Subjective memory complaints among women can indicate impaired higher-level functional capacity and may suggest higher one-year mortality rates.
我们旨在调查长期护理需求者或需要他人协助以维持功能能力者的主观记忆抱怨与更高水平功能能力之间的关联。
我们对60岁及以上的参与者进行了一项横断面研究。我们测量了主观记忆抱怨、更高水平的功能能力和抑郁症状，然后通过多元逻辑分析估计比值比（OR）。主观记忆抱怨用作预测变量，更高水平的功能能力用作结果变量，年龄、抑郁症状、糖尿病和高血压病史、外出频率、一年内跌倒情况以及体重指数作为可能的混杂因素。我们使用东京都老人综合研究所（TMIG）能力指数得分≤5作为临界值来评估更高水平的功能能力（该临界值与较高的一年死亡率相关）。
我们对501名60岁及以上的人进行了分析。在女性中，在调整年龄和抑郁症状后，主观记忆抱怨与更高水平功能能力受损相关（OR = 3.36；95%置信区间[CI]，1.59 - 7.08）。在男性中，在调整年龄和抑郁症状后，主观记忆抱怨与更高水平功能能力受损无显著关联（OR = 1.91；95% CI，0.88 - 4.12）。
女性的主观记忆抱怨可能表明更高水平的功能能力受损，并可能提示一年死亡率较高。
