Taxi ROADmAP Study for Overweight and Obesity

This study, called Taxi ROADmAP, is looking at ways to help taxi and for-hire vehicle drivers (like Uber or Lyft) who are overweight or obese. It will test four different approaches to help with weight loss: in-person counseling about diet and physical activity, text messages with tips, weekly phone calls for support, and tools to help you track your progress. The goal is to see how much weight participants lose over 12 months, how much these interventions cost, and how practical they are to use. This study is specifically for adults who are overweight (BMI 25-29) or obese (BMI 30 or higher).

Study design
This interventional study plans to enroll 1817 participants. It is designed to blend effectiveness and implementation studies to help translate findings into real-world use more quickly.
What's involved
Participants will receive counseling, text messages, phone calls, and self-monitoring tools. Your body weight will be measured at 12 months, and feasibility will be assessed for up to 12 months.
Compensation
Not stated in the trial record.
Follow-up
Your body weight will be followed for 12 months. The cost-effectiveness will be assessed for up to 6 months, and feasibility for up to 12 months.

What this trial measures

  • Difference in participant body weight from baseline to 12 months12-months post-intake

    Efficacy of intervention is achieved when participants have weight loss with a minimum threshold of 5% of overall body weight lost Intervention components include: * Initial in-person individual diet and physical activity (PA) counseling * Thrice-weekly diet/PA text messages * Weekly telephone support * Self-monitoring tools.

  • Estimate the cost and incremental cost-effectiveness of the obesity intervention componentsUp to 6 months

    Costs associated with each component include: 1) In-person counseling: personnel time, participant travel time, text messaging services; 3) Telephone support: personnel time; 4) Self-monitoring tools: food diaries and digital scales.

  • Feasibility of weight loss intervention for participants measured by the ROAmAP Process Evaluation QuestionnaireUp to 12 months

    The ROADmAP Process Evaluation Questionnaire will be administered to all participants to gather data on implementation potential. Questions are on a Likert scale and will collect intervention delivery facilitators and barriers, intervention sustainability facilitators and barriers post-study completion. Feasibility will be indicated by extreme Likert scores (Strongly Agree, Neutral, Strongly Disagree).
