Aim: To compare the knowledge and behavior of adolescents with risk factors associated with type 2 diabetes
mellitus after the implementation of two educational strategies. Method: Comparative and intervention
study with the participation of 60 students from two public schools divided into two groups: GA (n = 30) and
GB (n = 30). GA received individual educational intervention, while GB had group educational intervention.
We used questionnaires to assess the level of knowledge prior to intervention, in the day after it, and 60
days after the interventions, when we also assessed the intention of changing habits. Results: There was a
statistically significant increase in the level of knowledge as a result of both interventions. By comparing GA
and GB after the interventions, we observed that the intention to change habits were similar in both groups.
Conclusion: Both educational interventions were effective in raising knowledge and can be used in schools
for the prevention of T2DM in at-risk adolescents.
