Abstract

FERREIRA-MESQUITA, Alice et al. Factors associated with sarcopenia in institutionalized elderly. Nutr. Hosp. [online]. 2017, vol.34, n.2, pp.345-351. ISSN 1699-5198.  http://dx.doi.org/10.20960/nh.427.

Introduction:

The sarcopenia is a negative aspect for the health of the elderly, increased the risk for disease and mortality. Additionally can contributes greatly to functional reducing capacity and quality of life.

Objective:

To identify the prevalence and factors associated with sarcopenia in institutionalized elderly.

Methods:

This is a cross-sectional study, conducted with 216 elderly people, aged ≥ 60 years, of both sexes, residents in long-term care facilities in Salvador-Bahia, Brazil. To identify sarcopenia was used the skeletal muscle Index. Covariates were considered: gender, age, time of institutionalization, type of institution, body mass index and functional capacity. The Association between sarcopenia and covariates was evaluated using the Poisson regression model with robust variance.

Results:

The prevalence of sarcopenia in the elderly was 72.2% and this condition was associated with male sex (PR = 1,33; CI 95% = 1,08-1,65), thinness (PR = 1,29; CI 95% = 1,16-1,43) and obesity (PR = 0,37; CI 95% = 0,23-0,61).

Conclusion:

The prevalence of sarcopenia was high among the elderly living in long-term institutions, especially among men. Elderly with thinness showed greater impairment of muscle reserves, while the state of obesity was protective.
