Overview

Cross-sectional study investigates multimorbidity patterns in quilombola territories, highlighting health access inequities.

Key Points

  • This research aims to explore the interaction between geographic barriers and multimorbidity in quilombola communities.
  • Conducted a cross-sectional epidemiological study with 518 adults from nine quilombola communities.
  • Mapped geographic coordinates of communities and health services to classify accessibility levels.
  • Utilized surveys to gather data on sociodemographics, disease prevalence, and service utilization.
  • Developed a Composite Access Index to assess health service access incorporating distance and service use.
  • Applied a Random Forest model to identify predictors of multimorbidity.
  • Territorial heterogeneity was observed among communities, influencing health service access.
  • Service utilization varied significantly, with reliance on care outside territories reaching 70-95%.
  • A majority (72.5%) reported complete resolution of health issues, with community variations.
  • The Composite Access Index revealed Ituqui, Tiningu, and Murumurutuba as the most vulnerable areas.
  • Hypertension, diabetes, and arthritis were identified as key predictors of multimorbidity with high model accuracy.
