Abstract

This cross-sectional study assesses the prevalence and examines the role of social and demographic factors, health conditions, health system characteristics and contextual factors of under-utilization of medication for financial reasons among elderly women. Participants in the Greater Metropolitan Belo Horizonte Health Survey (GMBH) and the eleventh phase of the Bambuí Cohort Study of the Elderly were assessed. Among elderly women in the GMBH, the prevalence of under-utilization was 11.4%, and in Bambuí, the rate was 5.4%. Self-perception of health (OR, 3.46; 95%CI, 1.32_9.10); daily life limitations (OR, 2.75; 95% CI, 1.31-5.78) and perception of help (OR, 2.36; 95% CI, 1.07-5.25) had independent associations with under-utilization among GMBH residents. A poor perception of both cohesion in the neighborhood (OR, 2.38; 95% CI, 1.02-5.56) and the physical environment (OR, 2.58; 95% CI, 1.10-6.03) significantly increased the likelihood of under-utilization among Bambuí residents. These results provide important clues to identifying possible risk factors for under-utilization, highlighting the need to develop strategies targeting the amplification of the involvement between elderly women and their community to reduce the extent of under-utilization in later life.Este estudo transversal apresenta estimativas de prevalência e avalia o papel dos fatores sociodemográficos, condições de saúde, características do sistema de saúde e contextuais na subutilização de medicamentos por motivos financeiros entre as mulheres mais idosas. Participantes do Inquérito de Saúde da Região Metropolitana de Belo Horizonte (RMBH) e do décimo primeiro seguimento do Estudo de Coorte de Idosos de Bambuí foram avaliadas. Na RMBH, a prevalência da subutilização foi de 11,4%, e em Bambuí, foi de 5,4%. Autopercepção de saúde (OR = 3,46; IC95% = 1,329,10); limitações da vida diária (OR = 2,75; IC95% = 1,31-5.78) e percepção de ajuda (OR = 2,36; IC95% = 1,07-5,25) apresentaram associações independentes com a subutilização para as residentes na RMBH. Já a pior percepção de coesão ao bairro de moradia (OR = 2,38; IC95% = 1,02-5,56) e a pior percepção do ambiente físico (OR = 2,58; IC95% = 1,10-6,03) aumentaram significativamente a chance de subutilização em Bambuí. Estes resultados apresentam importantes evidências na identificação de fatores de risco para a subutilização e apontam para a necessidade de desenvolver estratégias para ampliar a integração das idosas em sua comunidade de modo a reduzir o impacto da subutilização na velhice.
