The mean age was 15.0 years (95% CI, 14.9-15.2 years) and mean BMI <jats:italic>z<\/jats:italic> score was 1.76 (95% CI 1.73-1.79). Elevated HbA<jats:sub>1c<\/jats:sub> was present in 8.6% (HbA<jats:sub>1c<\/jats:sub> 5.7%-6.4%: 8.3% [95% CI, 6.5%-10.5%]; HbA<jats:sub>1c<\/jats:sub> \u22656.5%: 0.3% [95% CI, 0.1%-0.7%]). Nearly one-third of youth with elevated HbA<jats:sub>1c<\/jats:sub> reported risk perception (30.1% [95% CI, 23.1%-38.1%), while one-quarter (26.5% [95% CI, 20.0%-34.2%]) had risk awareness. Risk perception was associated with increased TV watching (\u03b2\u2009=\u20090.3 hours per day [95% CI, 0.2-0.5 hours per day]) and approximately 1 less day per week with at least 60 minutes of physical activity (\u03b2\u2009=\u2009\u22121.2 [95% CI, \u22122.0 to \u22120.4) but not with nutrition or weight loss attempts. Awareness was not associated with health behaviors. Potential barriers had mixed associations: larger households (\u22655 members vs 1-2) reported lower consumption of non\u2013home-prepared meals (OR 0.4 [95% CI, 0.2-0.7]) and lower screen time (\u03b2\u2009=\u2009\u22121.1 hours per day [95% CI, \u22122.0 to \u22120.3 hours per day), while public insurance (vs private) was associated with approximately 20 fewer minutes per day of physical activity (\u03b2\u2009=\u2009\u221220.7 minutes per day [95% CI, 35.5 to \u22125.8 minutes per day]).<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi230360-10\"><jats:title>Conclusions and Relevance<\/jats:title><jats:p>In this cross-sectional study including a US-representative sample of adolescents with overweight or obesity, diabetes risk perception and awareness were not associated with greater engagement in risk-reducing behaviors in youth.
