*2.4. Exclusion and Inclusion Criteria*

The inclusion criteria used for this study focused on the words "social networks" or "social media", "health", and "young people". These terms were used based on the objectives of this study, as the purpose was to analyze the intervention of social networks in health. With the results from the terms "social networks" or "social media" and "health", researchers looked for positive and negative interactions or applications of these networks to health. Additionally, the term "young people" was used to identify this specific population, determine implications, and find previous studies focused on this group.

Other terms, such as "youth" or "young adults", were not included, as it would result in the inclusion of more data that were not adequately focused on young people. The boolean operators used were "OR" and "AND", to link the three terms.

The exclusion criteria used were the period of time for the production of the documents, and the use of terms focusing on the title, abstract, or keywords. Additionally, the type of document was determined in order to exclude non-scientific productions, such as obituaries.
