OBJECTIVE: This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023.
METHODS: The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373.
RESULTS: The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence.
CONCLUSIONS: The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.
目的:本研究旨在评估人口健康调查在估算2021年8月至2023年6月索罗卡巴市动脉高血压(AH)患病率方面的有效性。
方法:分析的性能指标是成人(≥18岁)AH患病率的精确度(设计效果-deff)及其对主要危险因素的暴露。总样本包括来自市区的1,080个人,被认为足以估计1.5的deff。这项基于集群的研究利用人口普查部门作为集群,通过家庭访谈收集的数据,标准化问卷,以及血压和生物参数的测量。使用的deff计算公式是加权方差/原始方差。研究伦理委员会批准了这项研究,注册CAAE30538520-1-0000-5373。
结果:deff值范围从慢性阻塞性肺疾病的0.44到哮喘的1.63,AH患病率的deff为1.00。
结论:该研究结果具有良好的精确性,参与者的高度接受和合作。研究的成本效益被认为是适当的。根据巴西地理研究所(IBGE)的详细制图和人口统计数据,在集群(人口普查部门)中选择家庭的技术被证明是实用和有效的,适合在其他城市复制和研究其他非传染性疾病。
