OBJECTIVE: To analyze ethical aspects of Brazilian articles on human visceral leishmaniasis, published after Resolution CNS 196/1996, and to analyze the policy on Brazilian periodicals on research ethics. METHODS: An explanatory study with a bibliographical and documental nature was conducted. Selection of publications on research involving human beings since 1996 was performed in the SciELO Brazil database. Gaps associated with editorial policies on medical periodicals, based on information obtained from the "Instructions to authors" section of each periodical, were analyzed. RESULTS: While there were no articles on the compliance with ethical aspects in the first four-year period (from 1997 to 2000), 75% fulfilled at least one of the ethical requirements evaluated in the first year (2009) of a subsequent four-year period (from 2009 to 2012). A total of six out of 11 periodicals indicated that the information about ethical aspects should be mentioned in the body of the article. There were three periodicals that required a letter or document, informing about compliance with these aspects and signed by the author(s), to be sent; two that requested a copy of the document used to obtain the free and informed consent; one that clarified the need of a copy to authorize the approval by the Committee on Ethics in Research; and four in which no requirements of ethical aspects were found. CONCLUSIONS: There was an improvement in the description of compliance with ethical aspects found in articles. Standardization of ethical requirements for human research in Brazilian periodicals is suggested. This could promote compliance with the presuppositions of documents regulating human research.
