A study was undertaken to evaluate the relationship between socioeconomic status (SES) and chronic musculoskeletal complaints (MSC), and to determine how this relationship is influenced by change in SES.
Two consecutive public health surveys within the county of Nord-Trøndelag, Norway, were conducted in 1984-86 (HUNT-1) and 1995-97 (HUNT-2). Among 46,901 adults who participated in both surveys, 24,127 persons (51%) in HUNT-2 who reported MSC continuously for at least 3 months during the past year were defined as having chronic MSC. Prevalence of chronic MSC was estimated at nine anatomical sites using multiple logistic regression with odds ratio (OR) and 95% confidence interval (CI) as measures of association with SES.
When defining SES by educational level, type of occupation, or income, low status was associated with increased prevalence of chronic MSC (age-adjusted analyses). The negative influence of low education or low occupation level was not eliminated by increasing the level of education or occupation from HUNT-1 to HUNT-2, in contrast with what was found for individuals with higher income level in HUNT-2 than in HUNT-1. The relationship with SES was more evident among individuals with musculoskeletal symptoms 15 days during the past month than among those with less than 15 days, evident at all nine different anatomical sites. The strongest relationship was found between low SES and prevalence of widespread chronic MSC.
Individuals with low SES had higher prevalence of chronic MSC than those with high SES. Future studies should try to clarify whether chronic MSC are a cause or consequence of low SES.
开展一项研究以评估社会经济地位（SES）与慢性肌肉骨骼疾病（MSC）之间的关系，并确定这种关系如何受到SES变化的影响。
在挪威北特伦德拉格郡进行了两次连续的公共卫生调查，分别于1984 - 1986年（HUNT - 1）和1995 - 1997年（HUNT - 2）开展。在参与了这两次调查的46901名成年人中，HUNT - 2中在过去一年里连续报告MSC至少3个月的24127人（51%）被定义为患有慢性MSC。使用多因素逻辑回归，以优势比（OR）和95%置信区间（CI）作为与SES关联的度量指标，估计了九个解剖部位的慢性MSC患病率。
当按教育水平、职业类型或收入定义SES时，低社会经济地位与慢性MSC患病率增加相关（年龄调整分析）。与HUNT - 2中收入水平高于HUNT - 1的个体不同，从HUNT - 1到HUNT - 2，教育水平或职业水平的提高并未消除低教育水平或低职业水平的负面影响。在过去一个月中有15天出现肌肉骨骼症状的个体中，与SES的关系比症状少于15天的个体更为明显，在所有九个不同的解剖部位均如此。低SES与广泛慢性MSC患病率之间的关系最为显著。
社会经济地位低的个体比社会经济地位高的个体慢性MSC患病率更高。未来的研究应试图阐明慢性MSC是社会经济地位低的原因还是后果。
