To describe the study design, operational strategies, procedures, and baseline characteristics of the Brazilian Amazon Region Eye Survey (BARES), a population-based survey of the prevalence and causes of distance and near visual impairment and blindness in older adults residing in the city of Parintins.
Cluster sampling, based on geographically defined census sectors, was used for cross-sectional random sampling of persons 45 years and older from urban and rural areas. Subjects were enumerated through a door-to-door survey and invited for measurement of uncorrected, presenting and best-corrected visual acuity and an ocular examination.
Of 9931 residents (5878 urban and 4053 rural), 2384 individuals (1410 urban and 974 rural) were eligible and 2041 (1180 urban and 861 rural) had a clinical examination (response rate 85.6%). The majority of participants were female (1041, 51.0%); the average age was 59.9 ± 11.1 years (60.2 ± 11.2 years for urban and 59.4 ± 11.1 years for rural); 1360 (66.6%) had primary schooling or less (58.1% in urban and 78.4% in rural) and 57.8% were resident in urban areas. The age distribution between sexes was similar (p = 0.178). Both sex and age distributions of the sample were comparable to that of the Brazilian Amazon Region population.
The BARES cohort will provide information about the prevalence and causes of near and distance vision in this underprivileged and remote population in Brazil.
描述巴西亚马逊地区眼部调查（BARES）的研究设计、操作策略、程序和基线特征。该调查是一项针对帕林廷斯市老年居民中远距离和近距离视力损害及失明患病率和病因的基于人群的调查。
基于地理定义的人口普查区进行整群抽样，对城市和农村地区45岁及以上人群进行横断面随机抽样。通过挨家挨户调查对受试者进行计数，并邀请他们测量未矫正视力、现有视力和最佳矫正视力，并进行眼部检查。
在9931名居民中（城市居民5878名，农村居民4053名），2384人（城市居民1410名，农村居民974名）符合条件，2041人（城市居民1180名，农村居民861名）接受了临床检查（应答率85.6%）。大多数参与者为女性（1041名，51.0%）；平均年龄为59.9±11.1岁（城市居民为60.2±11.2岁，农村居民为59.4±11.1岁）；1360人（66.6%）接受过小学及以下教育（城市居民为58.1%，农村居民为78.4%），57.8%的居民居住在城市地区。性别间年龄分布相似（p = 0.178）。样本的性别和年龄分布与巴西亚马逊地区人口的分布具有可比性。
BARES队列将提供有关巴西这个贫困和偏远人群中近距离和远距离视力患病率及病因的信息。
