Body mass index, muscle strength and physical performance in older adults from eight cohort studies: the HALCyon programme.
<h4>Objective</h4>To investigate the associations of body mass index (BMI) and grip strength with objective measures of physical performance (chair rise time, walking speed and balance) including an assessment of sex differences and non-linearity.<h4>Methods</h4>Cross-section...

Regression models were fitted within each study and meta-analysis methods used to pool regression coefficients across studies and to assess the extent of heterogeneity between studies.<h4>Results</h4>Higher BMI was associated with poorer performance on chair rise (N = 10,773), walking speed (N = 9,761) and standing balance (N = 13,921) tests. Higher BMI was associated with stronger grip strength in men only. Stronger grip strength was associated with better performance on all tests with a tendency for the associations to be stronger in women than men; for example, walking speed was higher by 0.43 cm/s (0.14, 0.71) more per kg in women than men. Both BMI and grip strength remained independently related with performance after mutual adjustment, but there was no evidence of effect modification. Both BMI and grip strength exhibited non-linear relations with performance; those in the lowest fifth of grip strength and highest fifth of BMI having particularly poor performance. Findings were similar when waist circumference was examined in place of BMI.<h4>Conclusion</h4>Older men and women with weak muscle strength and high BMI have considerably poorer performance than others and associations were observed even in the youngest cohort (age 53). Although causality cannot be inferred from observational cross-sectional studies, our findings suggest the likely benefit of early assessment and interventions to reduce fat mass and improve muscle strength in the prevention of future functional limitations.Rebecca HardyRachel CooperAvan Aihie SayerYoav Ben-ShlomoCyrus CooperIan J DearyPanayotes DemakakosJohn GallacherRichard M MartinGeraldine McNeillJohn M StarrAndrew SteptoeHolly SyddallDiana KuhHALCyon study teamPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 8, Iss 2, p e56483 (2013) |
