Polypharmacy, socioeconomic indicators and number of diseases: results from ELSA-Brasil.

OBJECTIVE: To estimate the prevalence of polypharmacy, describe the pharmacotherapeutic classes used, and investigate whether polypharmacy is associated with demographic and socioeconomic indicators, regardless of the number of diseases, among participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline (2008-2010). METHOD: In this analysis, 14,523 adults and elderly (35-74 years) participated. Polypharmacy was characterized as regular use of five or more medicines. The demographic and socioeconomic indicators analyzed were: gender, age, education level, per capita family income, and access to private health insurance. The independent association between demographic and economic indicators and polypharmacy was estimated by binary logistic regression. RESULTS: The prevalence of polypharmacy was 11.7%. The most used drugs were those with action on the cardiovascular system. After adjustments, including by number of diseases, the chances of being on polypharmacy treatment were significantly higher among women, older participants and those with greatest number of diseases. Individuals without health insurance had lower chance to be under polypharmacy, as well as those with lower income. CONCLUSION: The occurrence of polypharmacy among ELSA-Brasil baseline participants was mainly due to drugs for the treatment of chronic diseases. The relation between polypharmacy and the female gender, as well as its association with old age, are in consonance with the results obtained in other studies. Despite the absence of an association between polypharmacy and education level, the income and health insurance results reinforce the existence of social inequalities regarding drug use.

RESUMO: Objetivo: Estimar a prevalência de polifarmácia, descrever as classes farmacoterapêuticas utilizadas e investigar se a polifarmácia está associada a indicadores demográficos e socioeconômicos, independentemente do número de morbidades, entre os participantes na linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) (2008-2010). Métodos: Participaram desta análise 14.523 adultos e idosos (35-74 anos). A polifarmácia foi caracterizada como uso regular de cinco ou mais medicamentos. Os indicadores demográficos e socioeconômicos analisados foram: sexo, idade, escolaridade, renda familiar per capita e acesso a plano de saúde particular. A associação independente entre os indicadores demográficos e econômicos e polifarmácia foi estimada por meio de regressão logística binária. Resultados: A prevalência de polifarmácia foi de 11,7%. Os medicamentos mais utilizados foram aqueles com ação no sistema cardiovascular. Após ajustes, incluindo número de doenças, a chance de estar sob tratamento com polifarmácia foi significativamente maior entre mulheres, participantes mais velhos e aqueles com maior número de doenças. Participantes de baixa renda e aqueles sem plano privado de saúde, no entanto, tiveram menor chance de estar sob polifarmácia. Conclusão: A ocorrência de polifarmácia entre os participantes da linha de base do ELSA-Brasil deveu-se principalmente a medicamentos para o tratamento de doenças crônicas. A relação entre polifarmácia e sexo feminino, bem como sua associação com maior idade, estão em consonância com os resultados obtidos em outros estudos. Apesar da ausência de associação entre a polifarmácia e a escolaridade, os resultados de renda e plano privado de saúde reforçam a existência de desigualdades sociais em relação ao uso de medicamentos.

Concurrent and face validity of the MacArthur scale for assessing subjective social status: Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). / Validade Concorrente e de Face da Escala de MacArthur para Avaliação do Status Social Subjetivo: Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil).

This work assessed the concurrent and face validity of the MacArthur scale, which attempts to capture subjective social status in society, neighborhood and work contexts. The study population comprised a convenience sample made up of 159 adult participants of the ELSA-Brasil cohort study conducted in Minas Gerais between 2012 and 2014. The analysis was conducted drawing on Conceptual Metaphor Theory and using corpus linguistic methods. Concurrent validity was shown to be moderate for the society ladder (Kappaw = 0.55) and good for the neighborhood (Kappaw = 0.60) and work (Kappaw = 0,67) ladders. Face validity indicated that the MacArthur scale really captures subjective social status across indicators of socioeconomic position, thus confirming that it is a valuable tool for the study of social inequalities in health Brazil.

Resumo Este trabalho avaliou a validade concorrente e de face da escala de MacArthur, que busca aferir o status social subjetivo (SSS) na sociedade, na vizinhança e no trabalho. A amostra de 159 adultos, participantes da coorte ELSA-Brasil, em Minas Gerais (2012-2014), foi selecionada e a análise incluiu métodos epidemiológicos, a teoria cognitiva da metáfora e a linguística de corpus. A validade concorrente foi moderada para a escada da sociedade (kappaw = 0,55) e boa para a vizinhança (kappaw = 0,60) e do trabalho (kappaw = 0,67). A validade de face da escala de MacArthur mostrou que o instrumento realmente captura o SSS por meio dos indicadores de posição socioeconômica. Portanto, a escala de MacArthur demonstra ser um valioso instrumento para estudar as desigualdades sociais em saúde

[Participants recruitment in ELSA-Brasil (Brazilian Longitudinal Study for Adult Health)]. / Recrutamento de participantes no Estudo Longitudinal de Saúde do Adulto.

OBJECTIVE: To present the recruitment and communication strategies of the ELSA-Brasil (Estudo Longitudinal de Saúde do Adulto - Brazilian Longitudinal Study for Adult Health). METHODS: The strategies were directed at dissemination, institutionalization and recruitment. The communication actions intended to promote the strengthening of a positive institutional image for the study, knowledge management and an effective dialogue with its target audience. An official website was created in order to communicate with different audiences, to disseminate scientific knowledge, and to contribute to consolidate the image of the study within society. RESULTS: We recruited 16,435 men and women, active employees and retirees of six public institutions of education and research, to constitute the cohort of 15,105 participants. The recruitment goals were fully achieved in the six centers, with a slight predominance of women and of younger adults, and slightly fewer employees with lower level of schooling. CONCLUSIONS: The strategies used were adequate and essential to the successful inclusion and participation of the employees.

[Ethical issues in longitudinal studies: the case of ELSA-Brasil]. / Aspectos éticos em estudos longitudinais: o caso do ELSA-Brasil.

The debate about ethics in research with human beings has historically emphasized experimental studies because of their greater potential to harm the subjects involved. However, observational studies also include risks and relevant questions to be discussed. This article aims to present and discuss the ethical aspects involved in the implementation of ELSA-Brasil, a longitudinal multicenter study, with public funding, in which the research subjects and investigators are employees of the same institutions. The procedures adopted to meet the ethical requirements and commitments are described, as well as the casuistics that guided the actions according to their guiding principles (beneficence, autonomy and social justice). We present some moral problems that required consideration of risks and benefits at the confluence with the study's objectives, and we conclude with comments on the peculiarities and the potential benefits of a longitudinal study.

Aspectos eticos em estudos longitudinais: o caso do ELSA-Brasil / Ethical issues in longitudinal studies: the case of ELSA-Brasil

Historicamente a discussão acerca da eticidade dos atos em pesquisas com seres humanos privilegiou os estudos experimentais, pelo maior potencial de danos aos sujeitos envolvidos. Todavia, os estudos observacionais também envolvem riscos e suscitam questões relevantes. Neste artigo pretende-se apresentar e discutir aspectos éticos do desenvolvimento do ELSA-Brasil, um estudo longitudinal e multicêntrico, com financiamento público, no qual os sujeitos da pesquisa e pesquisadores pertencem às mesmas instituições. São descritos os procedimentos adotados para atender às exigências e compromissos éticos e a casuística que orientou as ações segundo seus princípios norteadores (beneficência, autonomia e justiça social). São apresentados alguns problemas morais que exigiram ponderação sobre riscos e benefícios na confluência com os objetivos do estudo e comentam-se peculiaridades de um estudo longitudinal e seus potenciais benefícios.
