“…This extends prior work based on self-report in other studies, which found obesity was associated with self-reported physical disability 6,9,10,13,15 and worse physical performance. [16][17][18][19] Previous studies showing that obesity among young and middle-aged adults predict physical disability in late-life relied on selfreported measures of physical function, [13][14][15] while this study used objectively measured physical performance. Physical performance tests are useful for predicting future disability, nursing home admission and mortality among high functioning elders.…”

“…15 Less is known about the role of obesity on objectively measured physical performance in late adulthood. [16][17][18][19] Thus, the objective of this study was to examine the association between weight history in young and middle adulthood and weight in late adulthood with physical performance in men and women aged 70-79. The association between weight history across all three time points and physical performance was also examined.…”

Objective: Although the association between current obesity and physical disability is well known, the cumulative effect of obesity is unknown. Using data from the Health, Aging and Body Composition study, we examined the association between weight history in young and middle adulthood and weight status in late adulthood with physical performance in late adulthood. Design: Longitudinal cohort study. Subjects: White and black men and women aged 70-79 years at study baseline (n ¼ 2803). Measures: Body mass index (BMI; kg/m 2 ) was calculated using recalled height at age 25 and weight at age 25 and 50 and measured height and weight at ages 70-79. Physical performance at ages 70-79 was assessed using a short physical performance battery (SPPB) and a 400-m walk test. Results: In this well-functioning cohort, approximately 24% of men and 8% of women reported being overweight or obese (BMI X25 kg/m 2 ) at age 25, 51% of men and 37% of women reported being overweight or obese at age 50, and 69% of men and 66% of women were overweight or obese at ages 70-79. Men and women who were obese (BMI X30 kg/m 2 ) at ages 25, 50 and 70-79 had significantly worse SPPB scores and 400-m walk times than those who were normal weight. Women who were overweight (BMI 25-29.9 kg/m 2 ) at ages 25, 50 and 70-79 also had significantly worse physical performance. Furthermore, men and women who had a history of being overweight or obese at ages 25 or 50 had worse physical performance compared to those who were normal weight throughout or who were overweight or obese at ages 70-79 but not in midlife or earlier.Conclusions: Maintaining a healthy body weight throughout adulthood may play a role in preventing or delaying the onset of physical disability.

“…Many of the previous large-scale observational studies have attempted to characterize this relationship in healthy, well-functioning older adults with relatively narrow age ranges (27). This may have resulted in an underestimation of any observed associations, as mobility-impaired elders are more likely to have lower muscle mass and reduced muscle strength when compared to elders of high functional status (6,14,26). Furthermore, many of the previous studies have also used selfreport methods to assess functional status.…”

“…Elders who lose their mobility have higher rates of falls and injury, chronic disease, dependency, institutionalization, and mortality (2)(3)(4)(5)(6). Consequently, the need to identify specific factors that influence mobility-disability has become increasingly important for optimizing appropriate intervention strategies.…”

Objectives-This study examined the influence of lower extremity body composition and muscle strength on the severity of mobility-disability in community-dwelling older adults.Methods-Fifty-seven older males and females (age 74.2 ± 7 yrs; BMI 28.9 ± 6 kg/m 2 ) underwent an objective assessment of lower extremity functional performance, the Short Physical Performance Battery test (SPPB). Participants were subsequently classified as having moderate (SPPB score > 7: n = 38) or severe mobility impairments (SPPB score ≤7: n = 19). Body composition was assessed using dual-energy X-ray absorptiometry and provided measures of bone mineral density (BMD), total leg lean mass (TLM) and total body fat. Maximal hip extensor muscle strength was estimated using the bilateral leg press exercise. Multiple logistic regression analysis was utilized to identify the significant independent variables that predicted the level of mobility-disability.Results-TLM was a strong independent predictor of the level of functional impairment, after accounting for chronic medical conditions, BMD, body fat, body weight and habitual physical activity. In a separate predictive model, reduced muscle strength was also a significant predictor of severe functional impairment. The severity of mobility-disability was not influenced by gender (p = 0.71). A strong association was elicited between TLM and muscle strength (r = 0.78, p < 0.01).Conclusions-These data suggest that lower extremity muscle mass is an important determinant of physical performance among functionally-limited elders. Such findings may have important implications for the design of suitable strategies to maintain independence in older adults with compromised physical functioning. Additional studies are warranted to assess the efficacy of lifestyle, exercise or therapeutic interventions for increasing lean body mass in this population.
