Back pain is one of the leading causes of disability and decreased quality of life. In this study, we examined the association between back pain and major depressive disorder (MDD) in six low- and middle-income countries. We also examined the association of back pain duration and severity with MDD among middle-aged and older adults in these countries.
Nationally representative data from the World Health Organization's Study on global AGEing and adult health (WHO-SAGE) consisting of 33,878 middle-aged and older adults aged 50 years or above were analysed. The linkages of back pain, pain duration and severity with MDD were examined using multivariable logistic regression analyses.
Across six countries, the prevalence of MDD was higher among middle-aged and older adults who reported back pain than those who did not report back pain (14.5 % vs 4.5 %). In the pooled data, middle-aged and older adults who suffered from back pain had higher odds of depression [adjusted odds ratio (aOR): 2.41, confidence interval (CI): 2.19-2.64] compared to those with no back pain. Particularly, the association was stronger in Ghana [aOR: 4.78] and South Africa [aOR: 2.42]. Further, the association was stronger for those who experienced back pain for >2 weeks as well as those who reported severe and extreme back pain than those with no back pain across all the countries.
In this study, the association of back pain and its duration and severity with MDD is consistent and significant among middle-aged and older adults in six countries. Government policies should consider the role of back pain in improving the mental health of middle-aged and older adults.
背痛是导致残疾和生活质量下降的主要原因之一。本研究旨在探讨六个中低收入国家背痛与重度抑郁症（MDD）之间的关系。我们还研究了这些国家中老年人背痛持续时间和严重程度与 MDD 之间的关系。
本研究使用了世界卫生组织（WHO）全球老龄化和成人健康研究（WHO-SAGE）的全国代表性数据，该研究包含 33878 名 50 岁及以上的中老年人。使用多变量逻辑回归分析来检验背痛、疼痛持续时间和严重程度与 MDD 的关联。
在六个国家中，报告背痛的中老年人患 MDD 的比例高于未报告背痛的中老年人（14.5% vs. 4.5%）。在汇总数据中，患有背痛的中老年人患抑郁症的可能性高于没有背痛的中老年人[调整后的优势比（aOR）：2.41，置信区间（CI）：2.19-2.64]。特别是在加纳（aOR：4.78）和南非（aOR：2.42），这种关联更强。此外，与没有背痛的人相比，背痛持续时间超过 2 周以及背痛严重和极度严重的人，其患病风险更高。
在这项研究中，背痛及其持续时间和严重程度与 MDD 之间的关联在六个国家的中老年人中是一致且显著的。政府政策应考虑背痛在改善中老年人心理健康方面的作用。
