Global, regional, and national burden of low back pain for adults aged 55 and older 1990-2021: an analysis for the global burden of disease study 2021.

BACKGROUND

Low back pain (LBP) is a widespread condition that increasingly affects the older adults, highlighting the need for a detailed examination of its global impact. Our research aimed to evaluate the LBP's burden and trends in individuals over 55 years of age across 204 countries and territories from 1990 to 2021.

METHODS

We analyzed the data from the Global Burden of Disease 2021, focusing on LBP prevalence, incidence, and years lived with disability (YLDs), along with associated risk factors.

RESULTS

In 2021, a total of 271,680,057 individuals aged 55 and older globally suffered from LBP. The age-standardized prevalence rate was 18,282.8 per 100,000 population, marking a 10.4% decrease since 1990. The age-standardized incidence and YLD rates had decreased by 9.4% and 11.0%, respectively. Central and Eastern Europe and Australasia had the highest burden, while Andean Latin America, Caribbean, and East Asia had the lowest. Notably, there were significant gender differences, with males experiencing lower rates than females. Occupational ergonomic factors, smoking, and high body mass index were identified as major contributors to the LBP burden.

CONCLUSION

This study analyzed the global burden of LBP in adults aged 55 and older, noting a decrease in age-standardized rates but an increase in total cases and regional disparities. It stressed the need to tackle modifiable risk factors like occupational ergonomics, smoking, and obesity to lessen LBP's impact. The study also called for region-specific, gender-sensitive healthcare policies to ensure fair health outcomes for all adults aged 55 and older.
