Socioeconomic disparities are suspected to play an important role in the
development of non-communicable chronic diseases and increase the risk for
mortality and morbidity among patients with end-stage renal disease. This study
aimed to investigate a possible association between educational levels, monthly
per capita income and prevalence of clinical comorbidities found in patients at
the initiation of the hemodialysis therapy. A sample of 214 patients was
analyzed. Patients were stratified according to their educational level in two
groups: ≤ 4 and > 4 years of formal education. For the monthly per capita income
the following groups were considered: < US$300.00, ≥ US$300.00 and
< US$450.00 and ≥ US$450.00. There was no statistical significant difference
regarding the prevalence of comorbidities when comparing different educational
levels. Similar results were found when monthly per capita income was analysed.
In spite of that, there was an elevated frequency of patients with ≤ 4 years of
formal education (73.36%, p<0.05) and with a monthly per capita income below
US$450.00 (80.84%, p<0.05) among those initiating hemodialysis therapy. In
conclusion, despite the fact that there was no statistical association between
the prevalence of comorbidities and socioeconomic factors our data indicated
that disadvantage populations might be at elevated risk to initiate dialysis
therapy in the city of Contagem, Brazil.
