Prevalence of chronic diseases and access to health services in brazil: Evidence of three household surveys

Abstract

Chronic non-communicable diseases (NCDs) are the leading causes of death globally, impacting heavily on the most vulnerable po-pulations. This study aimed to analyze changes in the prevalence of these diseases, health con-ditions, access, and health services in Brazil between 2008 and 2019. Tests of differences and generalized linear models were used as analy-tical tools, considering complex sampling from the PNAD 2008, PNS 2013, and PNS 2019 sur-veys, to test temporal changes in the prevalence and the prevalence ratio estimates, adjusted by sociodemographic variables. An increase in the prevalence of Depression, Diabetes, Cancers, Neuropsychiatric Disorders, Chronic Pulmo-nary problems, and Musculoskeletal problems was observed. A decline in rheumatoid arthritis, chronic renal failure, and diseases of the circu-latory system was identified. Among Brazilians with at least one NCD, an increase in coverage by the family health strategy over time was ob-served. However, there was a reduction in timely medical care and obtaining of free prescription drugs.
