Background & Aims
Chronic low back pain (LBP) is a prevalent condition among older adults (1), and it is associated with muscle mass loss, posing a risk for probable sarcopenia (2,3). Functional measures have been associated with increased disability in older adults (4). Given the recurring nature of chronic LBP in this population, they may be particularly prone to probable sarcopenia. In addition, low socioeconomic status has been shown to paly a role in the occurrence of both chronic LBP and sarcopenia (5). The aim of this study was to explore the association bewteen sociodemographic characteristics and probable sarcopenia in older adults with chronic LBP, utilizing sample data collected in both Italy and Brazil.
Methods
This comparative cross-sectional study used data from older adults (age ?60 years) seeking care for chronic LBP in Belo Horizonte, Brazil, and Rome, Italy. Sociodemographic characteristics included age, body mass index (BMI), education level, work status, marital status and the presence of probable sarcopenia was assessed by the algorithm developed by the European Working Group on Sarcopenia in Older People (6). The association between sociodemographic characteristics and probable sarcopenia was examined through binary logistic regression models, and odds ratio (OR) with corresponding 95% confidence intervals (CI) were calculated.
Results
A total of 200 older adults were included (Brazil, n=100; Italy, n= 100). Participants were predominantly women (Brazil, 74%; Italy, 61%) with a similar mean age and BMI. Probable sarcopenia was present in 55 (28%) participants (Brazil, n=30; Italy, n=25). The odds of having probable sarcopenia among those that complete the tertiary education was 0.38 times (OR = 0.38 [95% CI: 0.18, 0.79]) the odds among those who did not have education beyond primary school.
Conclusions
Our study showed that lower education levels were associated with probable sarcopenia in older people with chronic LBP.
