Abstract
Objective: To assess the prevalence of sarcopenia and associated factors among older women from the local community and older women living in Long-Term Care (LTC) institutions.Methods: A cross-sectional study conducted with 423 older women aged 60 or more, from the local community and older women aged 60 or more, living in LTC institutions. Sarcopenia was defined, according to the consensus of the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), including three criteria: low muscle strength (LMS) (<16kg); low muscle mass (LMM) (≤6.75kg/m2) assessed by a skeletal muscle mass index, and low physical performance (LPP) (≤0,8m/s) assessed by gait speed test. Older women who only showed LMS were considered to have pre-sarcopenia, those with LMS associated with LMM were diagnosed with sarcopenia and those who met all three criteria, were diagnosed with severe sarcopenia.Results: Among the community-dwelling older women, the prevalence of sarcopenia was 2.0% (from 60 to 69), 8.6% (from 70 to 79) and 12.9% (80 or more) and among the ones living in LTC Institutions, 3.3% (from 60 to 69), 14.8% (from 70 to 79) and 34.2% (80 or more). After multivariate logistic regression, age and low body mass index (BMI) were associated with sarcopenia in both groups.Conclusion: The prevalence of sarcopenia is higher among LTC older women. However, this is not an independent factor. In addition, regardless of residence, low BMI and advanced age are predictive for sarcopenia.
Highlights
According to the World Health Organization (WHO), world life expectancy is increasing
The prevalence of sarcopenia differs worldwide and may vary according to age, gender, parameters used for evaluation, cutoff points used for diagnosis and among communitydwelling and institutionalized[6] older people, which is the reason why it is more difficult to compare different studies to determine the real prevalence of sarcopenia in different populations
PR – Prevalence Ratio; CI – Confidence Interval. This cross-sectional study was carried out to assess the prevalence of sarcopenia and its association with residence and other variables in a city in southern Brazil using recommendations proposed by EWGSOP2
Summary
According to the World Health Organization (WHO), world life expectancy is increasing. Associated with the aging process and older people, recognized as a muscle skeletal disease, sarcopenia has as a key characteristic: Low. Strength. Accompanied by low muscle quantity and quality, according to European Working Group on Sarcopenia in Older People 2 (EWGSOP2)[4], which represents a significant change in the health status of older people and is associated with falls, fractures, functional decline, reduced life quality and increasing mortality in this population[5]. The prevalence of sarcopenia differs worldwide and may vary according to age, gender, parameters used for evaluation, cutoff points used for diagnosis and among communitydwelling and institutionalized[6] older people, which is the reason why it is more difficult to compare different studies to determine the real prevalence of sarcopenia in different populations
