The prevalence and burden of musculoskeletal (MSK) conditions are growing around the world, and low back pain (LBP) is the most significant of the five defined MSK disorders in the Global Burden of Disease (GBD) study. LBP has been the leading cause of non-fatal health loss for the last three decades. The objective of this study is to describe the current status and trends of the burden due to LBP in Brazil based on information drawn from the GBD 2017 study.
We estimated prevalence and years lived with disability (YLDs) for LBP by Brazilian federative units, sex, age group, and age-standardized between 1990 and 2017 and conducted a decomposition analysis of changes in age- and sex-specific YLD rates attributable to total population growth and population ageing for the purpose of understanding the drivers of changes in LBP YLDs rates in Brazil. Furthermore, we analyzed the changes in disability-adjusted life years (DALYs) rankings for this disease over the period.
The results show high prevalence and burden of LBP in Brazil. LBP prevalence increased 26.83% (95% UI 23.08 to 30.41) from 1990 to 2017. This MSK condition represents the most important cause of YLDs in Brazil, where the increase in burden is mainly related to increase in population size and ageing. The LBP age-standardized YLDs rate are similar among Brazilian federative units. LBP ranks in the top three causes of DALYs in Brazil, even though it does not contribute to mortality.
Findings from this study show LBP to be the most important cause of YLDs and the 3rd leading cause of DALYs in Brazil. The Brazilian population is ageing, and the country has been experiencing a rapid epidemiological transition, which generates an increasing number of people who need chronic care. In this scenario, more attention should be paid to the burden of non-fatal health conditions.
肌肉骨骼（MSK）疾病的患病率和负担在全球范围内不断增加，下背痛（LBP）是全球疾病负担（GBD）研究中定义的五种 MSK 疾病中最重要的一种。在过去的三十年中，LBP 一直是导致非致命性健康损失的主要原因。本研究的目的是根据 GBD 2017 研究提供的信息，描述巴西 LBP 负担的现状和趋势。
我们按巴西联邦单位、性别、年龄组和年龄标准化，估计了 1990 年至 2017 年 LBP 的患病率和残疾年（YLDs），并进行了年龄和性别特异性 YLD 率变化的分解分析，以了解人口增长和人口老龄化对巴西 LBP YLD 率变化的驱动因素。此外，我们分析了该疾病在这一时期的残疾调整生命年（DALY）排名的变化。
结果表明，巴西的 LBP 患病率和负担很高。1990 年至 2017 年，LBP 的患病率增加了 26.83%（95%UI 23.08 至 30.41）。这种 MSK 疾病是巴西 YLDs 最重要的原因，负担的增加主要与人口规模的增加和人口老龄化有关。巴西各联邦单位的 LBP 年龄标准化 YLD 率相似。LBP 在巴西 DALY 排名前三位，尽管它不会导致死亡。
本研究结果表明，LBP 是巴西 YLDs 最重要的原因，也是巴西 DALY 第 3 大原因。巴西人口老龄化，该国经历了快速的流行病学转变，这导致需要慢性护理的人数不断增加。在这种情况下，应更加关注非致命性健康状况的负担。
