Frailty and osteoporosis in older women--a prospective study.

UNLABELLED: Despite sharing common risk factors and biological pathways, the relationship between frailty and osteoporosis (OP) is not clear. This prospective study has shown that frailty defined by the Vulnerable Elders Survey can predict a decrease in bone mineral density after 1 year. Thus, frail older women should be assessed for osteoporosis. INTRODUCTION: Frailty and OP share common risk factors such as age, sarcopenia, lack of physical activity, low body weight, and smoking. Despite shared risk factors and biological pathways, the relationship between frailty and OP is not clear. The purpose of our prospective study was to examine this relationship in a community sample of older women. METHODS: A sample of 235 community-dwelling women was assessed for demographic, medical, frailty and OP status at baseline, and after at least 1 year. Frailty was assessed using the Cardiovascular Health study (CHS) frailty phenotype and using the Vulnerable Elders Survey (VES-13). OP was measured using dual photon absorptiometry bone mineral density (BMD). Descriptive statistics and regression models were used. RESULTS: At baseline, 235 women with a mean age of 77.6 (SD = 5.4), body mass index (BMI) of 28.3 (SD = 5.2) kg/m(2), and BMD of 0.7 (SD = 0.2) g/cm(2)were assessed. No correlation was found between BMD and the CHS (BMD spine, r = 0.009, p = 0.889; BMD hips, r = 0.050, p = 0.473) or the VES-13 (BMD spine, r = 0.034, p = 0.605; BMD hips, r = -0.042, p = 0.537) frailty scales. One hundred fifty-two (63.9 %) women were assessed after 1 year. In a regression model, women who were frail at baseline (VES-13) were found to have a statistically significantly lower hip and spine BMD at follow-up (controlling for BMI) than women who were non-frail at baseline (p = 0.0393, hip; p = 0.0069, spine). CONCLUSIONS: Frailty status as defined by the VES-13 predicts a decrease in BMD after 1 year.

Undetected dementia in community-dwelling older people: the Canadian Study of Health and Aging.

OBJECTIVE: To estimate the frequency and correlates of undetected dementia in community-dwelling older people. DESIGN: Secondary analysis of data from the Canadian Study of Health and Aging (CSHA) prevalence survey of dementia. SETTING: All 10 provinces of Canada excluding Indian reserves and military units. PARTICIPANTS: A total of 252 community-dwelling older adults diagnosed with dementia in the CSHA survey. MAIN OUTCOME MEASURE: Undetected dementia, defined as occurring in persons who meet standard diagnostic criteria for dementia but who report never having seen a doctor for memory problems. RESULTS: Of the 252 subjects, 64% had undetected dementia. Subjects with mild functional impairment were significantly more likely to have undetected dementia (odds ratio = 2.4, 95% confidence interval 1.2, 5.0). Older subjects and those with mild cognitive impairment showed a trend toward undetected dementia, although the results did not achieve statistical significance. Educational level, number of comorbid conditions, and degree of social support were not significantly associated with undetected dementia. CONCLUSIONS: A large number of older persons are living in the community with undetected dementia. These older people may be at significant risk for delirium, motor vehicle accidents, medication errors, and financial difficulties. As preventive strategies are developed and new cognitive enhancing therapies emerge, we need to reexamine our current guidelines about screening for cognitive impairment in older adults.

Who are older adults? Demographics and major health problems.

The care of older patients is a challenging and often rewarding experience. Elderly people can be helped to fulfill their needs and realize their goals with a sensitive and comprehensive evaluation, a positive and supportive attitude and an emphasis on illness rather than disease. Health care providers can contribute greatly to improved function and enhanced quality of life through an understanding of and respect for the individual qualities and aspirations of their older patients.
