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% women, and 38.8% black). Knee extension strength was measured with isokinetic dynamometry, grip strength with isometric dynamometry. Thigh…

Association of Muscle Mass, Area, and Strength With Incident Diabetes in Older Adults: The Health ABC Study.

Greater muscle area is associated with a lower risk of incident diabetes for older normal-weight women but not for men or overweight women, and this association differs by body mass index (BMI) category.


It is found that muscle strength was significantly lower in men with diabetes and not higher in women with diabetes despite of having greater muscle mass than those without diabetes, and muscle quality was consistently lower in both men and women with Diabetes than non-diabetic counterparts in both upper and lower extremities.

The loss of skeletal muscle strength, mass, and quality in older adults: the health, aging and body composition study.

Although the loss of muscle mass is associated with the decline in strength in older adults, this strength decline is much more rapid than the concomitant loss of Muscle mass, suggesting a decline in muscle quality.

Does the amount of fat mass predict age-related loss of lean mass, muscle strength, and muscle quality in older adults?

High fatness was associated with lower muscle quality, and it predicts accelerated loss ofLean mass, and Prevention of greater fatness in old age may decrease the loss of lean mass and maintain muscle quality and thereby reducing disability and mobility impairments.

Associations of Muscle Mass and Strength with All-Cause Mortality among US Older Adults

Low muscle strength was independently associated with elevated risk of all-cause mortality, regardless of muscle mass, metabolic syndrome, sedentary time, or LTPA among US older adults, indicating the importance of muscle strength in predicting aging-related health outcomes in older adults.

Grip strength, body composition, and mortality.

Grip strength is a long-term predictor of mortality from all-causes, cardiovascular disease, and cancer in men, though not in women and Muscle size and other indicators of body composition did not explain these associations.

Muscle strength, but not body mass index, is associated with mortality in patients with non-alcoholic fatty liver disease.

In this nationwide cohort of individuals with NAFLD, muscle strength, but not BMI, was independently associated with long-term overall mortality, and measuring handgrip strength can be a simple, non-invasive risk stratification approach for overall mortality in patients withNAFLD.

Toward a sex-specific relationship between muscle strength and appendicular lean body mass index?

Muscle strength appears to be associated with lean body mass; however, handgrip strength may be preferentially used in men and knee extension strength in women to detect sarcopenic individuals.

Muscle quantity is not synonymous with muscle quality.

Independent and joint associations of skeletal muscle mass and physical performance with all-cause mortality among older adults: a 12-year prospective cohort study

The combined use of hSMI and physical performance can provide improved risk stratification, which may be appropriately used as a screening tool targeting high-risk elders for the effective prevention of sarcopenia-related mortality.



Skeletal muscle strength as a predictor of all-cause mortality in healthy men.

Survival analysis examined the impact of grip strength and rate of change in strength on all-cause mortality over 40 years and found that in men <60 years, rate of loss of strength was more important than the actual levels, which persisted when muscle mass was considered.

Attenuation of skeletal muscle and strength in the elderly: The Health ABC Study.

It is demonstrated that the attenuation values of muscle on computed tomography in older persons can account for differences in muscle strength not attributed to muscle quantity.

Muscle strength and body mass index as long-term predictors of mortality in initially healthy men.

In healthy middle-aged men, long-term mortality risk was associated with grip strength at baseline, independent of BMI, and the possible interpretation of the finding is that early life influences on muscle strength may have long- term implications for mortality.

Relationship of interleukin-6 and tumor necrosis factor-alpha with muscle mass and muscle strength in elderly men and women: the Health ABC Study.

Higher plasma concentrations of IL-6 and TNF-alpha are associated with lower muscle mass and lower muscle strength in well-functioning older men and women, and may contribute to the loss of Muscle mass and strength that accompanies aging.

Appendicular skeletal muscle mass: effects of age, gender, and ethnicity.

The hypotheses that skeletal muscle is reduced in the elderly and that whole body 40K counting-derived total body potassium (TBK) provides a reasonable indirect assessment of skeletal muscle mass are supported.

Muscle quality and age: cross-sectional and longitudinal comparisons.

The relationship between muscle quality and age is dependent on how muscle mass is estimated and on whether subjects are studied cross-sectionally or longitudinally.

Body Composition in Healthy Aging

Health risks in elderly people cannot be evaluated simply in conventional terms of body fatness or fat distribution, and Elders at greatest risk are those who are simultaneously sarcopenic and obese.

Musculoskeletal fitness and risk of mortality.

The results suggest that some components of musculoskeletal fitness, particularly sit-ups (abdominal muscular endurance), are predictive of mortality in the Canadian population.

Association of IGF-I levels with muscle strength and mobility in older women.

In a study population including frail and healthy older women, low IGF-I levels were associated with poor knee extensor muscle strength, slow walking speed, and self-reported difficulty with mobility tasks, suggesting a role for IGF-i in disability as well as a potential target population for interventions to raise IGF- I levels.

It is not known whether testosterone replacement improves physical function and other health-related outcomes, or reduces the risk of disability, falls, or fractures in older men with low testosterone levels.
