The purpose of this study was to increase type 2 diabetes (T2DM) awareness and decrease T2DM risk factors by examining effectiveness of a modified version of the Centers for Disease Control and Prevention (CDC) Diabetes Prevention Program (DPP) with adolescents.

Design and Sample

A quasi-experimental one-group, pretest/posttest design was used to determine impact of the modified DPP on adolescents. Study intervention was incorporated into the health education curriculum at a public charter school and implemented over 11 weeks. Study sample included primarily African-American and Hispanic adolescents (N = 101) aged 13–18 attending the public charter school in a New Jersey urban community.


Instrumentation included valid, reliable measures of self-efficacy for healthy eating, physical activity, food knowledge, and healthy food choices. Participants' pretest/posttest waist circumference and body mass index (BMI) were collected.


Outcomes revealed significant (p < .001) increase in participants' food knowledge, self-efficacy for choosing healthy foods and performing physical activity, healthy food choices, and amount of weekly aerobic exercise. Reductions in BMI and waist circumference were statistically significant (p < .05).


A modified DPP adapted for adolescents' learning needs lowered risk for T2DM. Implications for clinical practice, education, and research are posed.
