Abstract

Brucellosis causes significant economic damage and public health problems in northwest China. The older rural population is considered a high-risk group. However, the epidemiological characteristics and risk factors for brucellosis in this population remain unclear. This study investigated these factors within this high-risk group by performing a cross-sectional study in five townships of Wuwei City, Gansu Province. Cases were screened via rose Bengal and serum plate agglutination tests. Risk factors were evaluated using a standard questionnaire form. This study included 1074 participants aged >50 years. Among them, 15 (1.4%) tested positive for Brucella. The most common symptoms were arthralgia/myalgia (n=5, 33.3%), and 10 (66.7%) cases were asymptomatic. Raising lambs artificially (odds ratio, 4.7; 95% CI, 1.3–17.0; P=0.02) increased the risk of brucellosis. The results indicated a high proportion of asymptomatic brucellosis in this group. Raising lambs artificially is a risk factor for brucellosis. The surveillance and health education of brucellosis for older rural populations in endemic areas of northwest China should been attention.

中国西北地区农村老年人布鲁氏菌病的流行病学特征和风险因素。

布鲁氏菌病在中国西北地区造成了严重的经济损失和公共卫生问题。农村老年人群被视为高危人群。然而，该人群的流行病学特征和布鲁氏菌病的风险因素仍不清楚。本研究通过在甘肃省武威市的五个乡镇进行横断面研究，调查了这一高危人群中的这些因素。病例通过玫瑰红和血清平板凝集试验进行筛查。使用标准问卷对危险因素进行评估。本研究共纳入 1074 名 50 岁以上的参与者。其中，15人（1.4%）的布鲁氏杆菌检测呈阳性。最常见的症状是关节痛/肌痛（5例，33.3%），10例（66.7%）无症状。人工饲养羔羊（几率比，4.7；95% CI，1.3-17.0；P=0.02）增加了布鲁氏菌病的风险。结果表明，该组无症状布鲁氏菌病的比例很高。人工饲养羔羊是布鲁氏菌病的一个风险因素。中国西北地区布鲁氏菌病流行区的老年农村人口应重视布鲁氏菌病的监测和健康教育。
