Título

Sleep complaints in older adults with chronic low back pain: a cross-sectional study

Introdução

Chronic low back pain (CLBP) can be highly disabling among older adults. Poor sleep quality has been associated with greater pain and disability in older adults with CLBP. However, there is a lack of data on the prevalence of sleep complaints and their association with CLBP outcomes in this population.

Objetivo

to investigate the 1) prevalence of sleep complaints among older adults with CLBP, and 2) associations of the three most prevalent sleep complaints with CLBP intensity and CLBP-related disability.

Métodos

This is a cross-sectional study. We recruited older adults (≥60 years old) with CLBP (≥3 months duration), who were seeking physiotherapy care in a primary care setting located in Belo Horizonte, Brazil. Our exclusion criteria were a CLBP intensity level of <3 on a 0-10 scale, significant cognitive decline (Leganes Cognitive Test score >4), and CLBP due to a specific cause (e.g., fracture, cancer, or infection). Participants answered the Sleep Complaints Questionnaire (sleep complaints assessment - prevalence of 15 pre-specified sleep complaints), Numerical Rating Scale (CLBP intensity assessment - 0-10 scale where 0 is no pain and 10 the worst pain imaginable), and Roland-Morris Questionnaire (CLBP-related disability assessment - 24 questions regarding the impact of CLBP on work-related and daily living activities). We ran six binary logistic regression models in which having/not having the sleep complaint was the dependent variable and scores at the Numerical Rating Scale and Roland-Morris Questionnaire were the independent variables. Models generated unadjusted ORs and 95% CIs.

Resultados

112 participants were recruited and 100 met our eligibility criteria for inclusion (69% women; mean age 69.8±6.6 years). Nearly all participants had at least one sleep complaint (96%). The most prevalent complaints were nocturnal awakenings (76%), snoring (57%), and insufficient sleep/waking up tired (55%). Reporting nocturnal awakenings (OR 1.09, 95%CI 1.01 to 1.17) and insufficient sleep/waking up tired (OR 1.14, 95%CI 1.04 to 1.26) were associated with greater CLBP-related disability. No other associations were found.

Conclusões

Most older adults with CLBP have at least one sleep complaint. Complaints related to fragmented sleep and non-restorative sleep are prevalent and may be associated with greater CLBP-related disability in this population. The high prevalence of snoring complaints may reflect the high prevalence of OSA in this population.
