在葡萄牙成年人口中进行了一项横断面的全国流行病学研究，旨在描述慢性疼痛(CP)的患病率和影响。5,094名参与者是在2007年1月至2008年3月期间通过随机数字拨号选出的，估计值充分考虑了总体情况。根据国际疼痛研究协会的定义，CP的患病率为36.7%(95%可信区间[CI][35.3-38.21])。85%的CP患者存在复发或持续性疼痛，68%的患者出现中到重度疼痛，35%的患者表现为残疾。老年、退休、失业和受教育程度较低的人群CP患病率最高。残疾程度最高的是家庭/家庭责任、娱乐活动、职业/工作和睡眠/休息；13%的人报告诊断为抑郁症，49%的人报告工作受到干扰。与残疾相关的主要因素是性别、疼痛强度和抑郁或抑郁症状。慢性支气管炎非常普遍，造成很高的个人和社会负担，尤其影响到最脆弱的亚群。根据CP的定义，葡萄牙可能被归入欧洲较低患病率组。建议改善疼痛强度管理，并特别注意CP的情感成分。在这项横断面的全国性流行病学研究中，我们显示慢性疼痛是一个严重的问题，存在于37%的葡萄牙成年人总人口中，与高个人、家庭和社会负担相关，尤其影响到人口中最脆弱的亚群。(C)2012年，美国疼痛协会
A cross-sectional nationwide epidemiological study was performed in a random sample of the Portuguese adult population, aiming to describe the prevalence and impact of chronic pain (CP). The 5,094 participants were selected by random digit dialing, between January 2007 and March 2008, and estimates were adequately weighted for the population. Prevalence of CP was 36.7% (95% confidence interval [Cl] [35.3-38.21), based on the definition of the International Association for the Study of Pain. Recurrent or continuous pain was present in 85% of those with CP, and moderate-to-severe intensity and disability were present in 68 and 35%, respectively. Highest CP prevalence was observed among the elderly, retired, unemployed, and less educated. Highest disability was found in relation with family/home responsibilities, recreational activities, occupation/work, and sleep/rest; 13% reported a diagnosis of depression and 49% reported interference in their job. The main factors associated with disability were sex, pain intensity, and depression or depressive symptoms. CP is highly prevalent, causes high personal and social burden, and affects particularly the most vulnerable subgroups. Portugal, depending on CP definition, could be placed in the lower prevalence group in Europe. Improvement in pain intensity management and special attention to affective components of CP are recommended.Perspective: In this cross-sectional nationwide epidemiological study, we showed that chronic pain is a significant problem that is present in 37% of the Portuguese adult general population, is associated with high personal, family, and social burden, and affects in particular the most vulnerable subgroups of the population.
