FIT24: Using Technology to improve activity and sleep in Hispanic youth (H-49195)



The purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy of a technology-based intervention that uses a Fitbit and text messages grounded in the Self-Determination Theory to promote healthy lifestyle habits and reduce risk for type 2 diabetes among a sample of Hispanic adolescents (14-16 years) with obesity.

Hispanic adolescents are disproportionately burdened by obesity (25.8% vs 18.5% general population) and type 2 diabetes (T2D) compared to non-Hispanic white youth. These disparities are driven in part by unhealthy lifestyle behaviors including low levels of physical activity (PA), excessive time spent in sedentary behaviors (SB), and short sleep durations. Given that Hispanic youth are the fastest growing pediatric subgroup in the U.S., there is a need to develop strategies to promote healthy activity and sleep behaviors.

This study has two aims. In the first aim we will conduct qualitative interviews with Hispanic adolescents (14-16 years) to determine the type of text-messages that would be most supportive, motivating, and helpful for improving their health behaviors. This information will be used in aim 2 to develop and test a 12-week intervention where a new sample of Hispanic adolescents with obesity will receive a Fitbit device and daily text messages to help them set and monitor goals for improving activity and sleep behaviors. For participating in still study, you will receive compensation.

The inclusion criteria to participate in this study is

  • self-identify as Hispanic
  • 14-16 years of age
  • Present with obesity
