although back pain is most prevalent in older adults, there is a paucity of studies investigating back pain in older people. Our objective was to characterize and compare Brazilian and Dutch older adults presenting to primary care with a new episode of back pain. We also aimed to investigate whether socio-demographic characteristics were associated with pain severity and disability.
we sourced data on 602 Brazilian and 675 Dutch participants aged ≥55 years with a new episode of back pain from the Back Complaints in the Elders consortium. We analyzed country differences in participants' characteristics, and associations between socio-demographic/clinical characteristics and pain severity and pain-related disability.
the two populations differed in most characteristics. More Dutch participants were smokers, heavy drinkers, and reported back stiffness. More Brazilian participants were less educated, had higher prevalence of comorbidities; higher levels of pain intensity, disability and psychological distress. When controlling for the effect of country, being female and having altered quality of sleep were associated with higher pain intensity. Altered quality of sleep, having two or more comorbidities and physical inactivity were associated with higher disability. Higher educational levels were negatively associated with both pain and disability outcomes.
back pain is disabling in the older population. Our country comparison has shown that country of residence is an important determinant of higher disability and pain in older people with back pain. Irrespective of country, women with poor sleep quality, comorbidities, low education and who are physically inactive report more severe symptoms.
尽管背痛在老年人中最为常见，但针对老年人背痛的研究却很少。我们的目的是描述和比较在初级保健中出现新背痛的巴西和荷兰老年人，并探讨社会人口学特征是否与疼痛严重程度和残疾相关。
我们从老年人腰背疼痛联合研究中获取了 602 名巴西和 675 名 55 岁及以上患有新背痛的参与者的数据。我们分析了两国参与者特征的差异，以及社会人口学/临床特征与疼痛严重程度和与疼痛相关的残疾之间的关联。
这两个人群在大多数特征上存在差异。更多的荷兰参与者吸烟、酗酒，并且报告背部僵硬。更多的巴西参与者受教育程度较低，患有更多的合并症，疼痛强度、残疾和心理困扰的水平更高。在控制国家效应后，女性和睡眠质量改变与更高的疼痛强度相关。睡眠质量改变、有两种或更多合并症以及缺乏身体活动与更高的残疾相关。较高的教育水平与疼痛和残疾结果呈负相关。
背痛在老年人群中具有致残性。我们的国家比较表明，居住国是影响背痛老年人更高残疾和疼痛的重要决定因素。无论国家如何，睡眠质量差、患有合并症、受教育程度低和缺乏身体活动的女性报告的症状更严重。
