Obesity and diabetes have been increasing at an alarming rate in the United States in both the adolescent and adult population. Lack of physical activity has been determined to be a primary cause of these two diseases. Additionally, the Centers for Disease Control and Prevention estimates the prevalence of obesity and diabetes to be higher among Mexican Americans compared to other ethnic groups. The objective was to explore health issues that concern Mexican American adolescents, determine the level of knowledge Mexican American adolescents have regarding health issues, and how they learn about these general health issues.
