Objective Overweight youth are at increased risk for prediabetes, characterized by elevated plasma glucose concentrations that do not reach the threshold for type 2 diabetes (T2D). Modifiable risk factors include dietary and physical activity behaviors which impact glycemia. As part of a pilot and feasibility study to prevent T2D via a lifestyle intervention, we aim to evaluate baseline dietary and physical activity factors and examine how these factors are related to measures of glycemia. Methods: Eligible participants are overweight youth (body mass index [BMI] > 85 th percentile; 10‐21 years). Dietary intake, physical activity and sedentary behavior are assessed using electronic monitoring techniques which have been validated in adolescents (4 days using Technology Assisted Dietary Assessment™ and 7 days using activPAL™, respectively). Glycemic status is assessed during a 2‐hour oral glucose tolerance test . Results: To date, 8 participants (5 females, BMI 29.4‐51.5 kg/m 2 ) have been screened and 4 had prediabetes. Dietary and activity behaviors are reported.Mean Range (% of Recommendations) Energy Intake (kcal) 1521 N/A Fat (g) 72.5 68 ‐ 148 % Saturated Fat (g) 25.5 94 ‐ 174 % Total Sugar (g) 101.5 N/A Fiber (g) 13.8 39 ‐64 % Fruit (cups) 1.0 7 ‐ 133% Vegetables (cups) 2.3 32 ‐ 152 % Whole Grains (oz) 1.3 0 ‐ 103 % Sweetened Drinks (8 fl oz) 1.2 N/A Sedentary Activity (hour:min, excluding sleep) 10:12 N/A Light Activity (hour:min) 0.59 N/A Moderate/Vigorous Activity (hour:min) 0.38 35 ‐ 82 %Conclusion Findings demonstrate inadequacy with regards to meeting recommendations for dietary and activity behavior. We expect to identify specific diet and activity behaviors that can be targeted in an intervention to prevent T2D in youth. (Indiana CTSI #UL1TR001108)
