..The objective of this study was to assess the association of inflammation with hyperglycemia (impaired fasting glucose [IFG]/impaired glucose tolerance [IGT]) and diabetes in older individuals...

..The loss of muscle mass is considered to be a major determinant of strength loss in aging. However, large-scale longitudinal studies examining the association between the loss of mass and strength in older adults are lacking...

..This study examines the association between incident mobility limitation and 4 lifestyle factors: smoking, alcohol intake, physical activity, and diet in well-functioning obese (n = 667) and non-obese (n = 2027) older adults...

..To compare two methods for classifying an individual as sarcopenic for predicting decline in physical function in the Health, Aging and Body Composition Study...

..This study evaluates standardized administration of an endurance walk test for identifying unrecognized and impending mobility limitation in community elders...

..The effect of the recent obesity epidemic on body composition remains unknown. Furthermore, age-related changes in body composition are still unclear...

..Dietary surveys suggest that many older, community-dwelling adults consume insufficient dietary protein, which may contribute to the age-related loss of lean mass (LM)...

..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...

..Longitudinal studies are needed to determine the direction of causality in this relationship...

..To examine the association between physical activity and inflammatory markers, with consideration for body fatness and antioxidant use...

..To examine the relationship between indicators of inflammation and the incidence of mobility limitation in older persons...

..However, it is unclear if these factors coexist or are independent in elderly people, and if a relationship does exist, whether it varies by sex and/or race...

..Fat distribution has been shown to be a strong correlate of hypertension, independent of general obesity. However, population-based studies are lacking on the association of regional fat depots with hypertension...
