Understanding the 24-Hour Activity cycle in Latino youth at risk for Type 2 Diabetes (H-46724)

This study will objectively assess wake time activities and sleep duration and their association with T2D risk in obese Latino adolescents and young adults. Adolescence and young adulthood are critical life periods for implementing health promotion and disease prevention programs.

The transition into adolescence is marked by a significant decrease in PA and shorter sleep duration. These behavior changes track strongly into young adulthood, increasing risk for diabetes. High-risk Latino adolescents and young adults are significantly underrepresented in research and little is known about activity and sleep behaviors and T2D risk during these critical life periods. Comparing obese Latino adolescents to young adults from the same population offers a unique opportunity to examine changes in activity and sleep patterns and T2D risk across a critical developmental transition in the life course. In contrast to PA, there is limited research focused on the determinants of SBs and sleep in youth and young adults.

Studies in older adults report that factors that predict levels of PA do not predict levels of SBs or sleep. Integrated mixed-methods (IMM) approaches combine quantitative and qualitative data, integrating objective measures with rich, contextual insights directly from participants who represent the community.

This study will fulfill the following specific aims:

• Aim 1: To examine associations between time spent in wake time activities, sleep duration, and diabetes risk in obese Latino adolescents and young adults.
• Aim 2: To explore determinants of wake time activities and sleep duration in obese Latino adolescents and young adults using an integrated mixed-methods approach.
• Aim 3: To examine differences in time spent in wake time activities, sleep duration, and diabetes risk between obese Latino adolescents (12-16 years of age) and young adults (18-22 years of age).
• Aim 4: Explore social determinants that influence participation in health promotion and disease prevention programming in Latino families.
