The objective of this study was to analyze the factors associated with functional decline and improvement in a community-dwelling population of people aged 75 years and older. A representative sample of elderly people living at home in the city of Sherbrooke (Quebec, Canada) was assessed yearly on three occasions (1991-1993) by a nurse. A health questionnaire, together with standardized instruments measuring disabilities, cognitive status, and depressive mood, was administered on the three assessments. From the 655 subjects who agreed to participate, a total of 504 subjects completed the study. The most important factors associated with functional decline were the number of days off regular activities (odds ratio (OR) = 1.31), the number of hot meals per day (OR = 1.59), and cognitive status (OR = 0.96), whereas weight loss (OR = 0.37) and living alone (OR = 0.54) were significant protective factors. Previous declines in functional autonomy, cognitive state, or mood were not independent risk factors. The most important factors associated with functional improvement were the disability score (OR = 1.08), previous functional decline (OR = 6.06), and decline in the disability score (OR = 1.09). Perceiving health to be worse than it was the previous year was a significant factor against improvement (OR = 0.24). This study identifies risk factors that can be helpful for targeting high-risk subgroups within the very elderly population who may benefit from a preventive program.
A retrospective analysis of the health and functional status of centenarians shows they are healthy and independent for most of their lives and experience a relatively rapid terminal decline.
OBJECTIVES: To examine any association between social, productive, and physical activity and 13 year survival in older people. DESIGN: Prospective cohort study with annual mortality follow up. Activity and other measures were assessed by structured interviews at baseline in the participants' homes. Proportional hazards models were used to model survival from time of initial interview. SETTING: City of New Haven, Connecticut, United States. PARTICIPANTS: 2761 men and women from a random population sample of 2812 people aged 65 and older. MAIN OUTCOME MEASURE: Mortality from all causes during 13 years of follow up. RESULTS: All three types of activity were independently associated with survival after age, sex, race/ethnicity, marital status, income, body mass index, smoking, functional disability, and history of cancer, diabetes, stroke, and myocardial infarction were controlled for. CONCLUSIONS: Social and productive activities that involve little or no enhancement of fitness lower the risk of all cause mortality as much as fitness activities do. This suggests that in addition to increased cardiopulmonary fitness, activity may confer survival benefits through psychosocial pathways. Social and productive activities that require less physical exertion may complement exercise programmes and may constitute alternative interventions for frail elderly people.
