The prevalence and years lived with disability caused by low back pain in China, 1990 to 2016: findings from the global burden of disease study 2016

The aim of this work was to quantify the prevalence and years lived with disability (YLDs) caused by low back pain (LBP) in China from 1990 to 2016. Data from the GBD 2016 (Global Burden of Diseases, Injuries, and Risk Factors Study 2016) were used. We analyzed the age-sex-province-specific prevalence and YLDs for LBP of 33 provinces/regions in China. Comparisons were made with the data retrieved from the 1990 GBD study. We estimated that 5.45 × 10(7) individuals had LBP in 1990, which rose to 6.73 × 10(7) in 2016. The age-standardized prevalence of LBP decreased from 5.6% (95% uncertainty interval [95% UI]: 4.9%-6.3%) in 1990 to 4.2% (95% UI: 3.8%-4.8%) in 2016. The YLDs for LBP increased from 6.2 million (95% UI: 4.3-8.3 million) in 1990 to 7.7 million (95% UI: 5.4-10.2) in 2016. Age-standardized YLD rate (per 100,000 person) decreased from 637.5 (95% UI: 449.9-848.8) in 1990 to 481.9 (95% UI: 338.6-637.0) in 2016. A female preponderance was observed for prevalence and YLDs. The prevalence and YLDs rate for LBP slightly decreased from 1990 to 2016 in China; however, the total individuals and YLDs increased. Low back pain still ranks as the second leading cause of YLD burden disease in China. Considerable attention should be paid for LBP, especially in the female population.
