Physical performance and muscle strength in older patients with and without diabetes from a public hospital in Lima, Peru

Abstract

Objective

To assess the relationship between physical performance (PP) and muscle strength (MS) in elderly subjects with and without diabetes in a public hospital of Lima, Peru.

Subjects and method

A cross-sectional analysis of subjects aged 60 years or older with and without diabetes. MS was measured with a handheld dynamometer, and PP with the “timed get-up-and-go” test. Nutritional status was determined using body mass index, body fat percentage measured with a handheld fat loss monitor and protein intake based on the 24-hour recall. Age, sex, and history of hospitalization and supplementation were also recorded. The association was assessed using adjusted prevalence ratios.

Results

Overall, 139 patients with diabetes (26.6% with low PP and 13.7% with decreased MS) and 382 subjects without diabetes (36.6% with low PP and 23.0% with decreased MS) were evaluated. No association was found between T2DM and MS (aPR: 0.99; 95% CI: 0.67–1.57) or PP (aPR: 1.13; 95% CI: 0.84–1.52). Protein and supplement consumption was also unrelated (p > 0.05); however, history of hospitalization, age, sex, nutritional status, and body fat percentage were related (p > 0.05).

Conclusions

No association was found between T2DM, MS, and PP. However, low PP was associated to female sex and overweight/obesity, and decreased MS was associated to high body fat percentage and underweight. Moreover, MS and PP were related to older age and history of hospitalization.
