CONTEXT Alendronate sodium reduces fracture risk in postmenopausal women who have vertebral fractures, but its effects on fracture risk have not been studied for women without vertebral fractures. OBJECTIVE To test the hypothesis that 4 years of alendronate would decrease the risk of clinical and vertebral fractures in women who have low bone mineral(More)
OBJECTIVES To compare two sarcopenia definitions and examine the relationship between them and lower extremity function and other health related factors using data from the baseline examination of the Health Aging and Body Composition (Health ABC) Study. DESIGN Observational cohort study. SETTING Two U.S. communities in Memphis, Tennessee, and(More)
OBJECTIVE To determine the efficacy of screening mammography by age, number of mammographic views per screen, screening interval, and duration of follow-up. DESIGN Literature review and meta-analysis. DATA IDENTIFICATION AND ANALYSIS: Literature search of English-language studies reported from January 1966 to October 31, 1993, using MEDLINE, manual(More)
BACKGROUND Lower muscle mass has been correlated with poor physical function; however, no studies have examined this relationship prospectively. This study aims to investigate whether low muscle mass, low muscle strength, and greater fat infiltration into the muscle predict incident mobility limitation. METHODS Our study cohort included 3075(More)
PURPOSE To critically review the risks and benefits of hormone therapy for asymptomatic postmenopausal women who are considering long-term hormone therapy to prevent disease or to prolong life. DATA SOURCES Review of the English-language literature since 1970 on the effect of estrogen therapy and estrogen plus progestin therapy on endometrial cancer,(More)
Lifetime risk is a useful way to estimate and compare the risk of various conditions. Hip fractures, Colles' fractures, and coronary heart disease, and breast and endometrial cancers are important conditions in postmenopausal women that might be influenced by the use of hormone replacement therapy. We used population-based data to estimate a woman's(More)
BACKGROUND Inflammation plays an important role in cardiovascular disease. The aim of this study is to investigate the predictive value of several inflammatory markers on the incidence of cardiovascular events in well-functioning older persons. METHODS AND RESULTS The subjects were 2225 participants 70 to 79 years old, without baseline cardiovascular(More)
OBJECTIVES To define clinically relevant cutpoints for usual gait speed and to investigate their predictive value for health-related events in older persons. DESIGN Prospective cohort study. SETTING Health, Aging and Body Composition Study. PARTICIPANTS Three thousand forty-seven well-functioning older persons (mean age 74.2). MEASUREMENTS Usual(More)
Because of the increasing number of elderly people in the United States, the total number of hip fractures in persons 50 years and older will rise from 238,000 to 512,000 by the year 2040, with a concomitant increase in avoidable deaths, disability, and medical costs. The total annual cost of hip fractures (in 1984 dollars) will increase from approximately(More)
BACKGROUND Although muscle strength and mass are highly correlated, the relationship between direct measures of low muscle mass (sarcopenia) and strength in association with mortality has not been examined. METHODS Total mortality rates were examined in the Health, Aging and Body Composition (Health ABC) Study in 2292 participants (aged 70-79 years, 51.6%(More)
