[Experience of importation of equipment for research in the ELSA-Brasil].

Objective: Policies that promote research in health were established in the last decade, developing the Brazilian scientific production. This development has not been accompanied by an improvement in the legal-institutional framework, thus hindering the development of research projects, including equipment importation activities. The present study aimed to analyze the equipment importation process for the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil).

[Publications committee of a multicenter study and computerized support system--publiELSA].

The publications committee of a multicenter study has the aim of organizing the proposals for articles, so as to ensure wide-ranging access to the data, quality and precedence.

Brazilian Longitudinal Study of Adult Health (ELSA-Brasil): objectives and design.

Although low- and middle-income countries still bear the burden of major infectious diseases, chronic noncommunicable diseases are becoming increasingly common due to rapid demographic, epidemiologic, and nutritional transitions. However, information is generally scant in these countries regarding chronic disease incidence, social determinants, and risk factors. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) aims to contribute relevant information with respect to the development and progression of clinical and subclinical chronic diseases, particularly cardiovascular diseases and diabetes.
