Resumo Objetivo: estimar a prevalência da doença renal crônica autorreferida e fatores associados em adultos residentes na Região Metropolitana de Manaus, Brasil. Métodos: estudo transversal de base populacional, de 2015, com amostragem probabilística para entrevistar adultos com idade ≥18 anos no domicílio; os fatores associados ao autorrelato de doença renal foram investigados por regressão de Poisson hierarquizada, para calcular as razões de prevalência (RP) e intervalos de confiança de 95% (IC95%), considerando-se a amostragem complexa empregada. Resultados: foram entrevistadas 4.001 pessoas - 52,8% mulheres, 72,2% pardos, 19,7% hipertensos; a prevalência de doença renal crônica foi de 2,1% (IC95% 1,6;2,5%), positivamente associada a idade (em anos: 35-44, RP=2,31, IC95% 1,02;5,21; 45-59, RP=2,52, IC95% 1,10;5,75; ≥60, RP=2,95, IC95% 1,21;7,16) e acidente vascular encefálico (RP=2,20, IC95% 1,09;4,45). Conclusão: dois em cada 100 adultos relataram doença renal crônica, mais frequente em mais velhos e com acidente vascular encefálico.
Abstract Objective: to estimate the prevalence of self-reported chronic kidney disease and associated factors in adults living in the Metropolitan Region of Manaus, Brazil. Methods: this was a population-based cross-sectional study conducted in 2015, with probabilistic sampling to select adults ≥18 years to be interviewed at home; factors associated with self-reported chronic kidney disease were investigated using hierarchical Poisson regression, to calculate prevalence ratios (PR) and 95% confidence intervals (95%CI), considering the complex sampling used. Results: a total of 4,001 people were interviewed - 52.8% were women, 72.2% were of brown skin color and 19.7% had hypertension; prevalence of self-reported chronic kidney disease was 2.1% (95%CI 1.6;2.5), it was positively associated with age (35-44 years old, PR=2.31, 95%CI 1.02;5.21; 45-59 years old, PR=2.52, 95%CI 1.10;5.75; ≥60 years old, PR=2.95, 95%CI 1.21;7.16) and having had strokes (PR=2.20, 95%CI 1.09;4.45). Conclusion: two out of every 100 Manaus metropolitan region inhabitants self-reported chronic kidney disease and it was more frequent in older adults and those who had had strokes.
Resumen Objetivo: estimar la prevalencia de la enfermedad renal crónica autoinformada y factores asociados en adultos residentes en la Región Metropolitana de Manaus, Brasil. Métodos: estudio transversal de base poblacional realizado en 2015, con muestreo probabilístico para seleccionar adultos ≥18 años; los participantes fueron entrevistados en domicilio; los factores asociados al autoinforme de enfermedad renal fueron investigados por la regresión de Poisson, para calcular las razones de prevalencia (RP) jerárquica e intervalos de confianza del 95% (IC95%), considerando el muestreo complejo utilizado. Resultados: fueron entrevistadas 4.001 personas - 52,8% mujeres, 72,2% pardos y 19,7% hipertensos -; la prevalencia de enfermedad renal autoinformada fue del 2,1% (IC95% 1,6;2,5), asociada positivamente con la edad (en años: 35-44, PR=2,31, IC95% 1,02 a 5,21; 45-59, PR=2,52, IC95% 1,10 a 5,75; ≥60, PR=2,95, IC95% 1,21 a 7,16) y accidente cerebrovascular (PR=2,20, IC95% 1,09 a 4,45). Conclusión: dos de cada 100 adultos informó enfermedad renal crónica, más frecuente en adultos mayores con accidente cerebrovascular.
