Prevalence, Deaths, and Disability‐Adjusted Life Years Due to Musculoskeletal Disorders for 195 Countries and Territories 1990–2017

Abstract

Objective To report the levels and trends of prevalence, deaths, and disability‐adjusted life years (DALYs) due to musculoskeletal disorders, categorized as low back pain, neck pain, osteoarthritis (OA), rheumatoid arthritis (RA), gout, and other musculoskeletal disorders, across 195 countries and territories from 1990 to 2017 according to age, sex, and Sociodemographic Index (SDI; a composite of sociodemographic factors). Methods Data were obtained from the Global Burden of Disease (GBD) Study 2017. The fatal and nonfatal burdens of musculoskeletal disorders were estimated using the Cause of Death Ensemble model and Bayesian meta‐regression tool, respectively. Estimates were provided for all musculoskeletal disorders and the corresponding 6 categories at global, regional, and national levels from 1990 to 2017. Counts and age‐standardized rates per 100,000 population along with 95% uncertainty intervals (95% UIs) were reported for prevalence, deaths, and DALYs. Results Globally, there were ~1.3 billion prevalent cases (95% UI 1.2 billion, 1.4 billion), 121.3 thousand deaths (95% UI 105.6 thousand, 126.2 thousand), and 138.7 million DALYs (95% UI 101.9 million, 182.6 million) due to musculoskeletal disorders in 2017. Age‐standardized prevalence, death, and DALY rates per 100,000 population were 16,276.2 (95% UI 15,495.5, 17,145.8), 1.6 (95% UI 1.4, 1.6), and 1,720 (95% UI 1,264.4, 2,259.2), respectively. Age‐standardized prevalence (−1.6% [95% UI −2.4, −0.8]) and DALY rates (−3.5% [95% UI −4.7, −2.3]) decreased slightly from 1990. The global point prevalence rate of musculoskeletal disorders in 2017 was higher in women than in men and increased with age up to the oldest age group. Globally, the proportion of prevalent cases according to category of musculoskeletal disorders in 2017 was greatest for low back pain (36.8%), followed by other musculoskeletal disorders (21.5%), OA (19.3%), neck pain (18.4%), gout (2.6%), and RA (1.3%). These proportions did not change appreciably compared with 1990. The burden due to musculoskeletal conditions was higher in developed countries. The countries with the highest age‐standardized prevalence rates of musculoskeletal disorders in 2017 were Switzerland (23,346.0 [95% UI 22,392.6, 24,329.8]), Chile (23,007.9 [95% UI 21,746.5, 24,165.8]), and Denmark (22,166.1 [95% UI 20,817.2, 23,542.1]). The greatest increases from 1990 were found in Chile (10.8% [95% UI 6.6, 15.4]), Benin (8.8% [95% UI 6.7, 11.1]), and El Salvador (8.5% [95% UI 5.5, 11.9]). Conclusion There is a large burden of musculoskeletal disorders globally, with some notable inter‐country variation. Some countries have twice the burden of other countries. Increasing population awareness regarding risk factors, consequences, and evidence‐informed treatment strategies for musculoskeletal disorders with a focus on the older female population in developed countries is needed, particularly for low back and neck pain and OA, which contribute a large burden among this cohort.

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial Assessing Efficacy and Safety of a Novel Low-Dose Turmeric Extract Formulation in Healthy Adults with Chronic Knee Pain

“…The global burden of disease study 2017 showed a large burden of musculoskeletal disorders, with approximately 1.3 billion cases globally. 49 Of these, the knee OA is among the most disabling musculoskeletal conditions. Inflammation is regarded as an important feature of early OA, and the altered inflammatory state induced by mechanical stress is considered an underlying cause.…”

Public interest in musculoskeletal symptoms and disorders during the COVID-19 pandemic

“…Musculoskeletal disorders are the leading cause of years lived with disability and the fifth most common cause of disability-adjusted life years worldwide in 2017 according to estimates from the Global Burden of Diseases [1][2][3]. Musculoskeletal disorders cause pain and functional disability [4][5][6], and their burden on individuals and society has been increasing worldwide [2,3,7]. Therefore, public interest in musculoskeletal disorders during the coronavirus disease 2019 (COVID-19) pandemic should be assessed to develop effective measures for the management of musculoskeletal disorders.…”

“…There are globally 1.3 billion cases of musculoskeletal disorders and over 121,000 deaths from such disorders, as well as nearly 139 million disability-adjusted life years, or the number of years lost due to ill-health, disability or early death [43]. Globally, the proportion cases in are led by the low back pain (37%); followed by "other"…”
