Acesso a planos de saúde na região metropolitana de Manaus em 2015: estudo transversal de base populacional*

Abstract

Objective: to analyze the frequency and factors associated with coverage by health insurance in the metropolitan region of Manaus, AM, Brazil. Method: a cross-sectional population-based study was conducted in 2015, with data collected through household interviews; prevalence ratios (PR) and confidence intervals (95%CI) were calculated using Poisson regression with robust variance adjusted for sex and age. Results: we interviewed 4,001 individuals; 13% (95%CI - 12.0;14.1%) had health insurance; greater insurance coverage was observed among military personnel (PR=3.18 - 95%CI 1.64;6.15), private sector employees (PR=1.91 - 95%CI 1.46;2.52) and public sector employees (PR=1.75 - 95%CI 1.23;2.49); health insurance was lower among poorer people (PR=0.21 - 95%CI 0.13;0.33), and those with less schooling (PR=0.66 - 95%CI 0.46;0.99). Conclusion: frequency of health insurance was low and was associated with better purchasing power, schooling, and employment.
