Association between race/color and incidence of hypertension in the ELSA-Brasil population: investigating the mediation of racial discrimination and socioeconomic position

Epidemiology of cardiometabolic health in Latin America and strategies to address disparities

In Latin America and the Caribbean (LAC), sociodemographic context, socioeconomic disparities and the high level of urbanization provide a unique entry point to reflect on the burden of cardiometabolic disease in the region. Cardiovascular diseases are the main cause of death in LAC, precipitated by population growth and ageing together with a rapid increase in the prevalence of cardiometabolic risk factors, predominantly obesity and diabetes mellitus, over the past four decades. Strategies to address this growing cardiometabolic burden include both population-wide and individual-based initiatives tailored to the specific challenges faced by different LAC countries, which are heterogeneous. The implementation of public policies to reduce smoking and health system approaches to control hypertension are examples of scalable strategies. The challenges faced by LAC are also opportunities to foster innovative approaches to combat the high burden of cardiometabolic diseases such as implementing digital health interventions and team-based initiatives. This Review provides a summary of trends in the epidemiology of cardiometabolic diseases and their risk factors in LAC as well as context-specific disease determinants and potential solutions to improve cardiometabolic health in the region.

Intersectional Discrimination Index: Initial stages of cross-cultural adaptation to Brazilian Portuguese

OBJECTIVE

To perform the cross-cultural adaptation of Intersectional Discrimination Index (InDI) into Brazilian Portuguese. InDI assesses the health impacts of intersectional experiences with anticipated (InDI-A), day-to-day (InDI-D), and major (InDI-M) discrimination.

METHODS

The following steps were taken: (1) independent translations; (2) synthesis of translations; (3) evaluation by an expert committee; (4) analysis by members of the target population; (5) back translation; and (6) pre-test. Based on the evaluation by the expert committee, the content validity coefficient (CVC) was calculated for each item and for the entire instrument. CVC helped identify which items needed adjustments according to the criteria of language clarity, theoretical relevance, and practical relevance.

RESULTS

Of the 31 items, 24 were considered adequate and seven required further language adjustments. CVC values were satisfactory for clarity (CVCt=0.86), practical relevance (CVCt=0.87), and theoretical pertinence (CVCt=0.87); a good level of understanding was reported by the target population (mean=4.44; standard deviation=1.36). The average response time was 15.5 minutes, and no additional difficulties in interpreting the items were reported. The back-translated InDI was approved by the original authors of the instrument.

CONCLUSION

The initial stages of the cross-cultural adaptation process showed that the use of InDI looks promising in Brazil. Further studies still need to examine the psychometric properties of the instrument to confirm the positive results of our work, as well as its usefulness for assessing the health impacts of intersectional experiences with discrimination.

Etapas iniciais da adaptação transcultural do Intersectional Discrimination Index para o português do Brasil

RESUMO Objetivo: O presente estudo realizou a adaptação transcultural do Intersectional Discrimination Index (InDI) para o português do Brasil. Trata-se de um instrumento composto de 31 itens, que visa mensurar os impactos para a saúde de experiências interseccionais com discriminação antecipada (InDI-A), cotidiana (InDI-D) e maior (InDI-M). Métodos: Foram percorridas as seguintes etapas: (1) traduções independentes; (2) síntese das traduções; (3) avaliação por comitê de especialistas; (4) análise por membros da população-alvo; (5) tradução reversa; e (6) pré-teste. Calculou-se igualmente o coeficiente de validade de conteúdo (CVC) de cada um dos itens e de todo o instrumento. O CVC foi empregado por permitir identificar quais itens necessitavam de ajustes de acordo com os critérios de clareza de linguagem, relevância teórica e pertinência prática. Resultados: Dos 31 itens do instrumento, 24 foram considerados adequados e sete necessitaram de ajustes de linguagem. Os valores dos CVC foram satisfatórios para os critérios de clareza de linguagem (CVCt=0,86), pertinência prática (CVCt=0,87) e relevância teórica (CVCt=0,87), e o público-alvo considerou satisfatória a compreensão do instrumento (média=4,44; desvio padrão=1,36). O tempo médio de resposta foi de 15,5 minutos e não foram registradas dúvidas adicionais. A tradução reversa foi aprovada pelos autores originais do instrumento. Conclusão: As etapas iniciais do processo de adaptação transcultural mostraram que o InDI parece promissor para uso no Brasil. Estudos futuros ainda precisam examinar as propriedades psicométricas do instrumento para confirmar os resultados positivos do presente trabalho, bem como sua utilidade para a avaliação dos impactos para a saúde de experiências interseccionais com discriminação.
