Learning Objective 1: Describe risk factors and the ways of preventing type 2 diabetes mellitus

Learning Objective 2: Modify lifestyle as of the knowledge acquired on risk factors and the ways of preventing type 2 diabetes mellitus

Purpose: The study investigated whether a structured program is more effective than information regarding the application of instruction strategies to prevent type 2 diabetes mellitus in risk adolescents.

Methods: Ninety adolescents took part in the study, and a pre-test has been applied before the interventions. Forty-five adolescents took part in a structured instruction program and forty-five adolescents received information upon the usage of an explanatory folder. Two post-tests were performed with both groups, one at the end of the intervention and the other 60 days after the intervention to determine changes in knowledge levels on risk factors and ways of preventing type 2 diabetes mellitus

Results: The comparison of results on pre and post-tests from both groups revealed a significant increase of knowledge level immediately after the intervention ending, and 60 days after intervention. No significant difference was found between the groups.


The study showed that both strategies are effective to increase the adolescents’ knowledge on risk factors for type 2 diabetes mellitus and the ways of prevention.
