Physical Frailty and Body Composition in Obese Elderly Men and Women

Abstract

VILLAREAL, DENNIS T., MARIAN BANKS, CATHERINE SIENER, DAVID R. SINACORE, AND SAMUEL KLEIN. Physical frailty and body composition in obese elderly men and women. Obes Res. 2004;12:913-920. Objective: To evaluate the prevalence of frailty and interrelationships among body composition, physical function, and quality of life in community-dwelling obese elderly (OE) persons. Research Methods and Procedures: Fifty-two OE, 52 nonobese frail, and 52 nonobese nonfrail subjects, matched for age and sex, were studied. Subjective and objective measures of functional status were evaluated by using the physical performance test, exercise stress test, lower extremity (LE) strength, gait speed, static and dynamic balance, functional status questionnaires, and health-related quality-of-life questionnaire (Medical Outcomes Short Form). Body composition was evaluated by using DXA, and muscle quality was evaluated by determining the ratio of LE strength to LE lean mass. Results: Among OE subjects, 96% met our standard criteria for mild to moderate frailty. Compared with the nonobese nonfrail group, the OE and nonobese frail groups had lower and similar scores in physical performance test, peak aerobic power, and functional status questionnaire, and exhibited similar impairments in strength, walking speed, balance, and health-related quality of life. Although absolute fat-free mass (FFM) was greater, the percentage body weight as FFM and muscle quality was lower in the OE group than in the other two groups. Discussion: Physical frailty, which predisposes to loss of independence, is common in community-living OE men and women. Physical frailty in OE subjects was associated with low percentage FFM, poor muscle quality, and decreased quality of life. These findings suggest that weight loss therapy may be particularly important in OE persons to improve physical function, in addition to improving the medical complications associated with obesity.

“…On the other hand, the results of our study line up with those obtained by other researches (De Hollander et al, 2013;Pan, Cole, & Geliebter, 2011;Villareal, Banks, Siener, Sinacore, & Klein, 2004), showing that obesity worsens quality of life, particularly its physical dimension. However, it would be necessary to analyze if body composition modifications imply improvement in the perceived level of quality of life.…”

Síndrome da fragilidade biológica em idosos: revisão sistemática

“…Em apenas três estudos os critérios de representatividade da amostra não foram identificados e a forma de seleção das pessoas do estudo foi por conveniência (13)(14)(15) Todos os estudos descritos na revisão abordavam a população na faixa etária igual ou acima de 65 anos, com exceção de dois estudos no qual abordavam a faixa etária de 43 a 86 anos (5) e acima de 50 anos (12), que foram incluídos na revisão por discriminar os resultados por faixa etária, sendo assim, utilizou-se apenas os resultados da amostra com 65 anos ou mais.…”

Total and regional relationship between lean and fat mass with increasing adiposity—impact for the diagnosis of sarcopenic obesity

“…A higher proportion of connective tissue alters the quality of FFM, which can lead to functional disability and mobility limitations. 36 We excluded subjects aged 440 years, because Kyle et al 26 demonstrated that age-related differences in body cell mass and total body potassium were greater than the differences in FFM or appendicular lean soft tissue suggesting an altered composition of FFM with lower SM in older subjects.…”
