Detailed Description
Hispanic adolescents are disproportionately burdened by obesity and type 2 diabetes compared to non-Hispanic white youth. Disparities in T2D emerge early in life and are driven in part by unhealthy lifestyle behaviors including low levels of physical activity, excessive time spent in sedentary behaviors and short sleep durations. Given that Hispanic youth are the fastest growing pediatric subgroup in the U.S., developing strategies to promote healthy lifestyle behaviors and addressing T2D disparities is a public health imperative. Wearable activity monitoring devices like Fitbits are designed to continuously monitor both wake time and sleep behaviors. Therefore the purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy of a 12-week 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 Hispanic adolescents with obesity.

Experimental: Intervention Fitbit Device Self-Determination Theory Text Messages |
Behavioral: Fit 24
This 12-week goal-setting intervention will test the feasibility of using a Fitbit watch and motivational text messaging to improve physical activity and sleep in Hispanic youth (14-16 years of age) with obesity. Youth will be prompted to set weekly steps per day and hours of sleep per night goals. Text messages will be grounded in the Self-Determination Theory and will provide evidence-based strategies, support, and motivation to encourage youth to meet their goals.

Outcome Measures
Primary Outcome Measures
- Number participants recruited and the number of participants that complete data collection [4 months]
We will record the number participants recruited, screened, and enrolled in the study. We will also record the percentage of participants that complete data collection.
- Number of technical issues experienced by participants [12-weeks]
We will record the number of technical issues experienced by participants throughout the study.
- Percentage of participants that are satisfied with participation in the study [12-weeks]
We will use a survey to assess the % of participants that are satisfied with participation in the study.
Secondary Outcome Measures
- Average of minutes of physical activity per day [4 months]
Physical activity will be assessed using accelerometry to assess average minutes/day using a 24-hour, 7-day accelerometer protocol.
- Average of minutes of sleep per night [4 months]
Sleep will be assessed using accelerometry to assess average minutes/night using a 24-hour, 7-day accelerometer protocol.
Other Outcome Measures
- Body Mass Index [4 months]
Height and weight will be measured to the nearest 0.1cm and 0.1 kg, using a portable stadiometer and research scale to calculate BMI percentile.
- Psychological need fulfillment as assessed using Psychological Need Satisfaction in Exercise Scale (PNSE) [4 months]
The Psychological Need Satisfaction in Exercise Scale (18-items) will be used to assess psychological needs fulfillment. The total possible scores in the PNSE are 6-108 with higher scores reflect greater perceptions of psychological need fulfillment.
- Autonomous motivation for physical activity as assessed using Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) [4 months]
The Behavioural Regulation in Exercise Questionnaire-2 (23-items) will be used to assess autonomous motivation for physical activity. The total possible scores on the BREQ-2 are -24 to 24, with a higher score indicating reflect more self-determined motivation whereas negative scores indicate less self-determined motivation.
