Background

Chronic back pain (CBP) can negatively affect one’s quality of life and health condition, posing significant social and economic burdens.

Objectives

(1) To determine the prevalence of CBP and analyze associated factors in adult and elderly individuals in a municipality in southern Brazil; (2) to verify who sought medical attention or missed work because of back pain; and (3) to estimate the impact of CBP on selected health outcomes.

Methods

This was a population-based cross-sectional study conducted with individuals aged 18 years and older. CBP was defined as “pain for three consecutive months in the cervical, thoracic, or lumbar regions in the last year.” Demographic, socioeconomic, behavioral, and physical and mental health information was collected. The impact of CBP was assessed by the etiological fraction method.

Results

The prevalence of CBP was 20.7% (95% CI: 18.3, 23.0) among the 1300 study participants. The factors associated with CBP were women, elderly, smokers, obesity, and sleeping fewer hours per night, as well as those with higher mental stress levels, history of fracture, arthritis/rheumatism, and work-related musculoskeletal disorder/repetitive strain injury. One-third of those with CBP missed work (31%) and 68% visited the physician over a 12-month period. All health outcomes analyzed (poor or very poor sleep quality, regular or poor health perception, worsened quality of life, depressive symptoms, perceived sadness) were significantly associated with CBP.

Conclusion

One in five adults or elderly reported having CBP over the previous 12 months. This condition was associated with poorer health perception, poorer quality of life, and depressive symptoms.

巴西南部成人和老年人慢性背痛的流行病学：一项横断面研究

背景

慢性背痛 (CBP) 会对一个人的生活质量和健康状况产生负面影响，造成重大的社会和经济负担。

目标

(1) 确定 CBP 的患病率并分析巴西南部城市成人和老年人的相关因素；（二）核实谁因腰痛就医或旷工；(3) 估计 CBP 对选定健康结果的影响。

方法

这是一项基于人群的横断面研究，对 18 岁及以上的人进行。CBP被定义为“去年颈椎、胸椎或腰椎区域连续三个月疼痛”。收集了人口统计、社会经济、行为以及身心健康信息。CBP 的影响通过病因学分数法进行评估。

结果

在 1300 名研究参与者中，CBP 的患病率为 20.7%（95% CI：18.3, 23.0）。与 CBP 相关的因素包括女性、老年人、吸烟者、肥胖和每晚睡眠时间较短，以及精神压力水平较高、骨折史、关节炎/风湿病和工作相关的肌肉骨骼疾病/重复性劳损。在 12 个月的时间里，三分之一的 CBP 患者（31%）和 68% 的人错过了工作。分析的所有健康结果（睡眠质量差或极差、健康状况正常或差、生活质量恶化、抑郁症状、悲伤感）都与 CBP 显着相关。

结论

五分之一的成年人或老年人报告在过去 12 个月内患有 CBP。这种情况与较差的健康感知、较差的生活质量和抑郁症状有关。
