Differences in predictors relevant to lifestyle characteristics and medical examination findings between disability and mortality in community-dwelling elderly persons

本研究探讨了老年人群中残疾和死亡之间的生活方式特征和医学检查结果相关的预测因素的差异。数据来源于对居住在高知县大月市的65岁及以上老年人进行的老龄化纵向研究，这些老年人在基线时没有身体残疾（N= 1，054）。在基线和随访时间点，通过对日常生活中6项身体活动（进食、排便、洗澡、穿衣、梳洗和行走）的自我报告评估身体残疾水平。在基线问卷调查中检查的生活方式特征包括五种健康习惯（吸烟、饮酒、睡眠时间、排便习惯和体育活动）和五种社会网络元素（生活安排、与儿童的接触、与近亲的接触、与密友的接触和参加团体组织）的可用性。获得了644人的体检结果 关于我们 根据老年人健康服务法，在基线时进行了基本健康检查。个体危险因素与多分类结局（身体独立vs身体依赖vs死亡）的相关性通过拟合多分类logistic回归进行检查。问卷调查中评估的排便习惯仅与残疾相关：排便习惯不规律受试者相对于排便习惯规律受试者的年龄和性别调整优势比为1.8（95%置信区间：1.0-3.2），残疾和1.3（95%置信区间：0.8-2.1）。对于医学检查结果，体重指数仅与残疾相关：体重指数低于或高于最佳范围的受试者相对于体重指数在最佳范围内的受试者的年龄和性别校正比值比为3.1（95%置信区间：1.3-7.5），死亡率为1.1（95%置信区间：0.7-1.9）。与残疾相关的因素不一定是死亡率的预测因子。它们应该相互区分。少

This study examined differences in predictors relevant to lifestyle characteristics and medical examination findings between disability and mortality in an elderly population. Data derived from a longitudinal study of aging for persons aged 65 and older who lived in Ohtsuki, Kochi prefecture and who had no physical disability at baseline(N=1,054). Levels of physical disability were assessed by self-reports on six items of physical activities of daily living (eating, toileting, bathing, dressing, grooming, and walking) at both the baseline and the follow-up time points. Lifestyle characteristics examined at the baseline questionnaire survey included five health practices (smoking, drinking, sleeping hours, bowel habit, and physical activity) and availability of five social network elements (living arrangements, contact with children, contact with close relatives, contact with close friends, and attendance at group organizations). Medical examination findings were obtained for 644 person … More s who had the basic health examination under the Health Services for the Elderly Act at baseline. Associations of individual risk factors with a polychotomous outcome (physically independent vs physically dependent vs dead) were examined by fitting a polytomous logistic regression. Bowel habit assessed in the questionnaire survey was associated with disability only : age and gender adjusted odds ratios for subjects with irregular bowel habits relative to those with regular habits were 1.8 (95 % confidence interval : 1.0-3.2) for disability and 1.3 (95 % confidence interval : 0.8-2.1) for mortality.For the medical examination findings, body mass index was related to disability only : age and gender adjusted odds ratios for subjects with body mass index below or over the optimum range relative to those in the optimum range was 3.1 (95 % confidence interval : 1.3-7.5) for disability and 1.1 (95 % confidence interval : 0.7-1.9) for mortality. Factors associated with disability were not necessarily predictors of mortality. They should be differentiated from each other. Less
