The domains of physical activity are not able to predict sleep quality in older adults with low back pain: A longitudinal study


For healthy aging, the regular practice of physical activity has been indicated as it generates further health benefits. However, it is unknown in a single cohort if physical activity domains can predict improvement in sleep quality and clinical outcomes in the elderly with low back pain.


To verify the predictive ability of physical activity domains on sleep quality in older adults with low back pain.


Older adults with low back pain were recruited and assessed through a home interview at baseline and after 6 months. This was a longitudinal study with a 6-month follow-up. Multivariate linear regression analyses were performed to verify whether the levels of physical activity in leisure time, sports and household tasks, measured by the Baecke Physical Activity Questionnaire Modified for the Elderly, predict an improvement on sleep quality at 6 months follow-up. The analysis was adjusted by the following covariates: age, gender, body mass index (BMI), mental state, depression, comorbidities, and somnolence.


A total sample of 231 older adults with low back pain were included, between March 2017 and December 2018, consisting of 177 (76.6%) women, mean age of 71 years. Final regression models showed no evidence of association between the domains of baseline physical activity with sleep quality at 6 months follow-up, domestic, sports, and leisure.


Our findings suggest that the different domains of physical activity do not influence the sleep quality in older adults with low back pain at 6 months follow-up.
