Together on Diabetes Study: Evaluation of a Pilot Diabetes Prevention and Management Program for American Indian Youth

The objective of the Together on Diabetes study is to test the efficacy of a pilot intervention to improve the prevention and management of type 2 diabetes among American Indian youth.

The primary aim of this study is to determine the impact of the Together on Diabetes pilot intervention on youth diabetes risk behaviors, including:

• Improvement in youth dietary intake, with a specific focus on reducing the percent of total calories from fat.
• Improvement in youth physical activity, with a specific focus on increasing the number of minutes of physical activity each week.

An additional primary aim of the study is to determine the feasibility and acceptability of the pilot intervention and evaluation, including program adherence and program satisfaction.

The secondary aim of this study is to determine the feasibility of collecting data to determine program impact on a number of physiological measures.

Study Overview

• Status: Completed
• Conditions: Diabetes
• Intervention / Treatment: Behavioral: Together on Diabetes-Hopkins

Detailed Description

This is a single group pre-post study designed to evaluate the feasibility and effectiveness of a pilot intervention at improving the prevention and management of type 2 diabetes among American Indian youth. The intervention uses a Family Health Coach model to work with families of youth with diabetes or at high risk of diabetes. Health Coaches visit families in their homes and conduct intervention sessions with both youth and a designated adult 'support person' (e.g., parent, guardian, etc). For Youth Participants, the pilot intervention consists of 12 sessions (45-60 minutes in duration) delivered during a 6-month intervention phase, plus 6 check-ins delivered during a 6-month follow-up phase. There are also 4 optional social support visits for the Youth Participants in order to provide necessary assistance with challenges the youth may be facing. For Support Persons, the pilot intervention consists of 4 family skill building sessions (20-30 minutes in length) delivered during the first 4 months of the Youth Participant's intervention phase. Support Persons will also be welcomed and encouraged to attend any of the Youth Participant sessions. All sessions are designed to be taught at the participant's home, but they may also occur at another location chosen by the participant (e.g. school, study office, clinic). Outcome data will be collected at Baseline, 3 months following Baseline, 6 months following Baseline, and 12 months following Baseline.

Intervention / Treatment

Experimental: Together on Diabetes-Hopkins

Behavioral: Together on Diabetes-Hopkins; The Johns Hopkins Center for American Indian Health, with support from Bristol-Myers Squibb Foundation, Inc. is adapting a Family Health Coach model for diabetes prevention with four southwestern tribal communities. Specifically, Johns Hopkins Center for American Indian Health has designed a paraprofessional delivered pilot intervention aimed at improving the prevention and management of type 2 diabetes among American Indian youth. For Youth Participants, the pilot intervention consists of 12 sessions delivered during a 6-month intervention phase, plus 6 check-ins delivered during a 6-month follow-up phase. For Support Persons, the pilot intervention consists of 4 family skill building sessions delivered during the first 4 months of the Youth Participant's intervention phase.
