Rheumatoid arthritis affects approximately between 0.3 and 1.2% of the world population. In Latin America, different studies have estimated a prevalence between 0.2 and 0.5% in the population over 16 years of age.
To identify the epidemiological profile of rheumatoid arthritis.
Descriptive cross-sectional design carried out in an urban population of a social security institution in Mexico. The information of the clinical file of 373 patients was studied. The epidemiological profile included the sociodemographic dimension, family history, health, clinical, therapeutic, biochemical, extra-articular manifestations and complications. Statistical analysis percentages, means, confidence intervals for percentages and confidence intervals for averages were calculated.
The wrists were the most affected joints with 44.6% (95% CI: 39.5-49.6%). The extra-articular manifestation with the highest prevalence was asthenia with 9.9% (95% CI: 6.9-12.9%); predominant diagnosis according to ICD-10 was seropositive rheumatoid arthritis with 59.8% (95% CI: 54.8-64.8%), and the rheumatoid factor was highly positive in 78.3% (95% CI: 74.1-82.5%); predominant treatment was with combined therapy at diagnosis in 97.6% (95% CI: 96.0-99.1%). The duration of treatment was > 10 years in 34.1% (95% CI: 29.2-38.8%).
This work has described the epidemiological profile of the patient with rheumatoid arthritis in different dimensions.
类风湿关节炎影响着全球约0.3%至1.2%的人口。在拉丁美洲，不同研究估计16岁以上人群的患病率在0.2%至0.5%之间。
确定类风湿关节炎的流行病学特征。
在墨西哥一家社会保障机构的城市人口中进行描述性横断面设计。研究了373例患者的临床档案信息。流行病学特征包括社会人口学维度、家族史、健康状况、临床情况、治疗情况、生化指标、关节外表现及并发症。计算了统计分析中的百分比、均值、百分比的置信区间和均值的置信区间。
手腕是最常受累的关节，占44.6%（95%置信区间：39.5 - 49.6%）。患病率最高的关节外表现是乏力，为9.9%（95%置信区间：6.9 - 12.9%）；根据国际疾病分类第10版（ICD - 10）的主要诊断是血清阳性类风湿关节炎，占59.8%（95%置信区间：54.8 - 64.8%），类风湿因子高度阳性的比例为78.3%（95%置信区间：74.1 - 82.5%）；主要治疗方式是诊断时联合治疗，占97.6%（95%置信区间：96.0 - 99.1%）。治疗时间超过10年的患者占34.1%（95%置信区间：29.2 - 38.8%）。
本研究从不同维度描述了类风湿关节炎患者的流行病学特征。
