摘要

The scope of the current study was to analyze the methodological differences between Brazilian anthropometric and dietary surveys, which are classified as home, school and telephone surveys, as well as to reflect on the potential benefits and obstacles involved in the use of secondary data. The documents that are the focus of this study are official published reports of the surveys. The results indicated methodological differences in the assessment of food intake, anthropometry, frequency and form of access to the databases. The secondary data sources, which were previously limited to the dissemination of printed reports, were made available as micro-data in electronic databases. However, these databases are as yet not frequently consulted by health researchers due to the complexity of data extraction and analysis. For this reason, courses on how to develop skills to use these databases in graduate health courses should be included as they contain variables related to the health and nutrition status of the population, in addition to socioeconomic and demographic variables, which are not found in traditional health information systems. The conclusion drawn is that working with secondary data requires training and that the use of this source of information contributes to adequate planning in health.
