About

The purpose of the proposed study is to pilot a 6-month, cognitive-behavioral binge eating intervention, Appetite Awareness Training (AAT) to reduce binge eating and prevent weight gain for Black women with a BMI > 25 kg/m^2 and with weekly binge eating episodes. Intervention participants will receive a 8-week group AAT intervention, and will also receive bluetooth-connected scales for daily weighing. Participants will also receive tailored feedback on self-weighing frequency and weight change. The investigators will follow-up with participants at six months.

Full description

Aim 1. Using an experimental design, examine the feasibility and acceptability of 6-month AAT (N=40) in North Carolina. Forty overweight and obese (BMI ≥ 25 kg/m^2) community-based Black women will be randomized to the AAT intervention or wait-list control (who will eventually receive the intervention). AAT participants will meet weekly for 8 weeks, followed by a 4-month period of daily weighing and weekly tailored feedback only. The study will examine the following: recruitment feasibility, attendance/retention, adherence, satisfaction, and barriers to completion.

Aim 2: At 4 and 6 months, compare changes in (a) binge eating, eating self-efficacy, and depressive symptoms and (b) weight, blood pressure, and waist circumference for participants in the intervention vs. control group.

H_1: Participants in the AAT intervention will report less binge and overeating and gain less weight than those in the control group at 2 and 6 months.

Secondary aim: Examine characteristics (e.g., baseline BMI, severity of binge eating, frequency of self-weighing) related to change in binge eating and weight.

Participants will receive an 8-week Appetite Awareness Training (AAT) program using a group format, will be provided a smart scale (with bluetooth connection) and instructions to weigh themselves daily. Participants will also be provided with weekly tailored feedback on self-weighing frequency and weight change. Assessment will be conducted at 0, 2, and 6 months.

Treatment:

Behavioral: Appetite Awareness Treatment + Lifestyle Modification
