Describe the sampling design and other methodological aspects of the Study of Chronic Diseases (Edoc).
Edoc comprises two household surveys with distinct populations, one with adults aged 18 to 59 years (Edoc-A) and another with older adults aged 60 years or more (Edoc-I), living in Rio Branco, Acre. The selection of the participants used complex samples by clusters in two stages of selection, census enumeration areas (CEA) and household. In the first stage, common to both surveys, 40 CEAs were selected with probability proportional to size, and in the second stage, independent for each survey, households were selected with equal probability, and all the residents eligible for each survey were selected. Sampling weights were estimated by the inverse of the product of inclusion probabilities at each stage and then calibrated to produce unbiased population estimates. Interviews were held with questionnaires about socioeconomic and demographic conditions, life habits and health conditions. Anthropometric measures focused on measures of body height, girths and mass, while the vital signs analyzed were blood pressure, heart rate and respiratory rate. Blood and urine samples were collected for analysis.
The Edoc comprised 1,701 participants, 685 of Edoc-A and 1,016 of Edoc-I. Considering the loss of information of some participants and the need of studying specific themes with production of population inferences, 16 subsamples of complete information by theme were generated and two subsamples were exclusive of Edoc-I.
The Edoc has as important developments the analyses of epidemiological profile of the population from the capital of the state of Acre, contributing to the production of knowledge in public health with useful information for decisions in public health policies.
描述慢性病研究（Edoc）的抽样设计及其他方法学方面。
Edoc包括两项针对不同人群的家庭调查，一项针对18至59岁的成年人（Edoc - A），另一项针对60岁及以上的老年人（Edoc - I），他们居住在阿克里州的里奥布兰科。参与者的选择采用两阶段整群抽样的复杂样本，第一阶段为普查枚举区（CEA），第二阶段为家庭。在第一阶段，两项调查共同进行，按规模大小概率抽样选取40个CEA；在第二阶段，每项调查独立进行，以相等概率选取家庭，并选取所有符合每项调查条件的居民。抽样权重通过各阶段入选概率乘积的倒数进行估计，然后进行校准以产生无偏的总体估计。通过问卷调查社会经济和人口状况、生活习惯及健康状况。人体测量指标重点关注身高、腰围和体重，同时分析的生命体征包括血压、心率和呼吸频率。采集血液和尿液样本进行分析。
Edoc共有1701名参与者，其中Edoc - A有685名，Edoc - I有1016名。考虑到部分参与者信息缺失以及研究特定主题并进行总体推断的需要，按主题生成了16个完整信息子样本，其中两个子样本仅属于Edoc - I。
Edoc的重要进展在于对阿克里州首府人群的流行病学概况进行分析，为公共卫生知识的积累做出贡献，并为公共卫生政策决策提供有用信息。
