Abstract

Background: Caregivers in Japan experience a high prevalence of low back pain (LBP), with age, sex, individual pain experiences, and central sensitization symptoms potentially influencing its chronic progression.

Objective: To determine the prevalence of LBP among caregivers, as well as its relation to age and sex, and explore work status, psychological factors, and central sensitization symptoms as contributing factors to chronic LBP (CLBP).

Methods: A large-scale cross-sectional survey was conducted among 1214 caregivers in 35 geriatric healthcare facilities. The survey assessed LBP and CLBP prevalence, work status, psychological factors, and central sensitization-related symptoms. Multivariate logistic regression analysis was used to identify factors influencing CLBP.

Results: Among 936 valid respondents, the LBP prevalence was 69.2%. No significant sex differences were found in the prevalence of LBP and CLBP. Old age, higher pain severity, and severe symptoms related to central sensitization increased the risk of CLBP. However, work status and psychological factors did not significantly contribute to CLBP.

Conclusion: There is a high prevalence of LBP among caregivers, age and individual pain experience significantly impact CLBP. These findings emphasize the need for therapeutic strategies to manage pain intensity, especially in the acute phase, to prevent the progression to chronicity.

Keywords: Chronic pain; central nerve system sensitization; prevalence; psychology; risk factors.
