Skeletal muscle function and need for long-term care of urban elderly people in Japan (the Bunkyo Health Study): a prospective cohort study.

ABSTRACT:

Purpose

The proportion of elderly individuals (age ?65 years) in Japan reached 27.7% in 2017, the highest in the world. A serious social problem in a super-aged society is the rise in the number of elderly people who need long-term care (LTC), which is mainly due to cerebrovascular disease, dementia, age-related frailty, falls and fractures, and joint disease. We hypothesised that decreased muscle mass, muscle strength and insulin sensitivity are the common risk factors for these diseases related to needing LTC. We developed a prospective cohort study of elderly subjects in an urban community to test this hypothesis. The primary objective is to prospectively investigate associations between muscle mass, muscle strength, and insulin sensitivity and incidence of main disease and risk factors of needing LTC. The primary outcomes are the incidence of cerebrovascular disease and cognitive decline.

Participants

Participants were 1629 people aged 65-84 years living in 13 communities in an urban area (Bunkyo-ku, Tokyo, Japan). Average age was 73.1±5.4 years.

Findings to date

We obtained baseline data on cognitive function, cerebral small vessel disease (SVD) determined by brain MRI, body composition, bone mineral density, arteriosclerosis, physical function, muscle mass, muscle strength and insulin sensitivity. Mild cognitive impairment and dementia were observed in 18.1% and 3.3% of participants, respectively. The prevalence of cerebral SVD was 24.8%. These characteristics are similar to those previously reported in elderly Japanese subjects.

Future plans

We will ask participants about their health status, including incidence of cerebrovascular disease, falls, fractures and other diseases every year by mail. We plan to re-evaluate cognitive function, brain MRI parameters and other parameters at 5 and 10 years after the baseline evaluation. We will evaluate whether low muscle function (muscle mass, muscle strength or insulin sensitivity) is a risk factor for cognitive decline or cerebrovascular disease.

Project description:BACKGROUND:Hip fracture is an important social and medical problem due to its increasing prevalence, the consequences for health and the economic impact on the health care system, but there is no doubt that it also has repercussions on health-related quality of life (HRQoL). Hence the importance of understanding and determining the impact of the condition on everyday life from the perspective of the patient's physical, emotional and social well-being. PURPOSE:To determine the impact of hip fracture on HRQoL of people over the age of 65 1 month after surgery, related factors and the effects on functional ability and mood. METHODS:Prospective observational study conducted in the traumatology units of two university hospitals in the province of Cáceres with consecutive sampling of all patients over the age of 65 admitted for hip fracture surgery during the study period. Sociodemographic and clinical data were recorded at the time of admission and prospectively at the follow-up visit 1 month later. Clinical, social, quality of life (EQ-5D-), basic functional and instrumental capacity (Barthel Index (BI) and Lawton & Brody Scale), and geriatric depression (Yesavage) variables were collected. RESULTS:The study included 224 patients with a median age of 84.6?years (SD?±?6.1), 76.3% were female. Charlson's comorbidity was 5.3 (SD?±?1.2). The EQ-5D index decreased from 0.62 (SD?±?0.35) to 0.16 at 1?month follow up (SD?±?0.20) p <? 0.001. The mean Visual Analog Scale (VAS) score of EQ-5D decreased from 72.8 (SD ±15.8) to 48.3 (SD?±?17.2) p?<? 0.001. All dimensions of EQ-5D showed a significant reduction from the time of pre-fracture status to 1 month after surgery. Independent factors associated with HRQoL 1 month after surgery were pre-fracture status Barthel Index score, Lawton and Brody scale, presence of depression, and type of surgery. CONCLUSIONS:After a hip fracture, patients experience considerable deterioration in their HRQoL, especially in self-care, daily activities, and mobility. There is also a significant decline in functional capacity for both the basic and instrumental activities of daily living. One month after surgery, HRQoL is a long way from pre-fracture levels.
