Epidemiology of sarcopenia

Article Abstract:

More effort should be put into finding an operational definition of sarcopenia, or age-related muscle loss. A substantial part of the older population has low levels of muscle mass, which is associated with physical disability. A population-based cross-sectional age-stratified survey has been carried out to look at muscle mass change patterns and to estimate prevalence of sarcopenia.

Characteristics of nondisabled older persons who perform poorly in objective tests of lower extremity function

Article Abstract:

Past and cross-sectional correlates of poor lower-extremity performance were seen in 3,381 persons aged 71 or older interviewed and given a battery of physical performance tests at the sixth annual follow-up of the Established Populations for Epidemiologic Studies of the Elderly. The group with poor performance had high prevalence of diabetes and hip fracture and high levels of biological markers of inflammation. It has a high percentage of women and represents about 10% of the US population 70-90 years old. This information is relevant for planning for preventing disability.

Alcohol use and functional disability among cognitively impaired adults

Article Abstract:

Among cognitively impaired adults, moderate and heavy drinkers had better basic activities of daily living (BADL) function and former drinkers had poorer instrumental activities of daily living (IADL) function vs those who had never been drinkers based on a study of alcohol use and functional disability. Consistent findings are lacking and the relationships seem to be complex. A dose-response effect was not established with small numbers of light and heavy drinkers was an impediment. Prospective studies that use other exposure measurements and function tests may give more understanding of effects of alcohol in cognitively impaired elderly. Effects of alcohol for health and functioning of those beyond age 64 have not been adequately characterized.
