Correção da prevalência autorreferida em estudos epidemiológicos com grandes amostras

Abstract: Resumo: As prevalências de doenças são úteis para a formulação e avaliação de políticas públicas. A medida autorreferida é comumente utilizada por ser fácil de ser coletada e não exigir treinamento específico em saúde ou custo adicional. Todavia, esse processo de mensuração pode gerar uma medida enviesada. Objetivou-se apresentar os métodos existentes para ajustar a prevalência, com base na autorreferida, focando nos problemas computacionais no caso de amostras grandes e propondo uma solução alternativa. Os mé… Show more

“…Antibody TestingTo detect IgG and IgM anti-SARS-CoV-2 antibodies, we performed the rapid test MedTest Coronavirus 2019-nCoV IgG/IgM, from MedLevensohn manufacturer (Yuhang District, China): an immunochromatographic assay which combines SARS-COV-2 antigen-coated particles to qualitatively detect IgG and IgM antibodies. The MedTest Coronavirus (covid-19) …”

“…Finally, it should be considered that hypertension in the PNS is a morbidity reported by the interviewee according to the diagnosis attributed by the doctor, and the level of sensitivity and specificity of the issue may affect the population prevalence of this morbidity. However, this method has a lower prevalence bias than the self-reported disease measure 27 . Even so, the method used in the PNS does not prevent the possible association of the magnitude and distribution of SAH with greater access and regular use of health services, especially when they reside in locations with greater access to health actions and services.…”
