2000年2月干旱月份在埃塞俄比亚古拉奇地区(人口超过150万)进行了一项横断面研究，以确定沙眼和失明的严重程度。采用多阶段整群抽样方法确定研究对象。由训练有素的眼科护士对学龄前儿童(1-6岁)进行活动性沙眼检查。1~6岁儿童活动性沙眼患病率为56.5%，海拔3000米以下为5.7%，海拔2000米以下为73.4%(P<；0.001)。活动性沙眼在配偶儿童中比在女性儿童中更常见，并在3岁年龄组达到顶峰(63.2%)，随着年龄的增长而下降。其中45%的家庭到水源的距离只有15分钟。只有6%的家庭有厕所。确认活动性疾病和态度之间的联系可能有助于绘制埃塞俄比亚和其他地方的沙眼地图。可能是低态度村庄的苍蝇密度较高，导致了所看到的差异。(C)2005年皇家热带医学和卫生学会。爱思唯尔有限公司出版。版权所有。
A cross-sectional study was conducted in the dry month of February 2000 in the Gurage Zone of Ethiopia (population over 1.5 million) to determine the magnitude of trachoma and blindness. A multistage cluster sampling was applied to identify the study subjects. Pre-school children (1-6 years) were examined for active trachoma by trained ophthalmic nurses. The prevalence of active trachoma in the 1-6-year-old age group was 56.5%, ranging from 5.7% (altitude > 3000m) to 73.4% (altitude less than 2000 m) (P < 0.001). Active trachoma was more common in mate children than in female children and peaked in the 3-year-old age group (63.2%), declining with age. The distance to a source of water for 45% of these households was only 15 min. Only 6% of the households had latrines. Confirmation of the association between active disease and attitude may assist with mapping of trachoma in Ethiopia and elsewhere. It is possible that fly density, higher in villages at low attitudes, contributed to the differences seen. (c) 2005 Royal Society of Tropical Medicine and Hygiene. Published by Elsevier Ltd.
