Arms & Interventions
Healthy Juntos Intervention Condition
Parent-adolescent dyads randomized to the Healthy Juntos intervention condition will access a program that includes didactic, behavioral, and positive parenting content from their smartphones for 8 weeks.
Intervention: Healthy Juntos (Behavioral)
Control Group
This group will receive a digital standard of care - a list of publicly available lifestyle apps and websites which they may access at their discretion.
Outcomes
Primary Outcomes
Change in Adolescents Physical Activity
Time Frame: Baseline, up to 2 months
Adolescents will self-report physical activity using the Youth Activity Profile.
Change in Adolescent Sedentary Behavior
Time Frame: Baseline, 2 months
Adolescents will self-report sedentary behavior using the Youth Activity Profile.
Change in Adolescents Dietary Intake (Sugar)
Time Frame: Baseline, up to 2 months
Adolescent-parent dyads will self-report dietary intake using the NHANES Dietary Screener Questionnaire. Teaspoon equivalents of added sugars.
Change in Adolescents Dietary Intake (i.e., Fruits/Vegetables)
Time Frame: Baseline, 2 months
Adolescents will self-report dietary intake using the NHANES Dietary Screener Questionnaire. Cup equivalents of fruits and vegetables will be calculated using a scoring algorithm developed by the National Cancer Institute.
Secondary Outcomes
- Change in Parents Dietary Intake (Sugar)(Baseline, up to 2 months)
- Change in Parent Physical Activity.(Baseline, up to 2 months)
- Change Parent Sedentary Behavior(Baseline, up to 2 months)
- Change in Parents Dietary Intake (i.e., Fruits/Vegetables)(Baseline, up to 2 months)
