Clinical Trial Summary

This lifestyle behavior intervention aims to weight loss in low-income overweight or obese mothers of young children through promotion of stress management, healthy eating, and physical activity. All eligible women will be assigned to the intervention group. The intervention will last 3 weeks and will be delivered via weekly web and individual health coaching sessions.

Description:

Previous research in lifestyle behavior weight loss intervention has 3 limitations. (1) Low-income overweight or obese mothers of young children have been significantly underrepresented. (2) Prior lifestyle interventions in overweight or obese mothers have suffered from threats to internal validity and have not specifically addressed motivation, emotion, and cognition (especially executive function), all of which are critical for promoting and maintaining healthy lifestyle behaviors and health outcomes. (3) There has been little evidence that any of the potentially efficacious strategies researched previously were even possible under real-world conditions. The proposed small pilot study builds on strength and effectively addresses limitations of prior research. The ultimate goal of the proposed study is to create a more feasible and scalable intervention that can be easily implemented and sustained in real-world settings. This self-directed, web-based goal-oriented episodic future thinking intervention will focus on increasing motivation (autonomous motivation and self-efficacy) and improving emotion (emotion control and stress) and cognition (impulsivity). the will lead to weight loss and decrease risk of chronic conditions associated with obesity, for example, hypertension, type 2 diabetes, and cancer. All eligible women will be assigned to the intervention group. The intervention will last 3 weeks and will be delivered via weekly web and individual health coaching sessions. We will enroll 30 low-income overweight or obese mothers of young children with diverse racial and ethnic backgrounds. All participants will be assessed at baseline (T1) and immediately after the three-week intervention (T2). Specific aims are to to (1) assess intervention fidelity (dose, delivery, receipt) and acceptability by the study participants, (2) investigate potential intervention impact on the primary (body weight) and secondary outcomes (waist circumference), (3) explore potential intervention impact on lifestyle behaviors (diet and physical activity), (4) explore potential intervention impact on motivation (autonomous motivation, self-efficacy, social support), emotion (emotion control, stress), and cognition (impulsivity), and (5) assess cost of different recruitment approaches.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in body weight	Self-reported body weight	baseline (T1) and 3 weeks follow up (T2)
Secondary	Waist circumference	Self-reported pants size will be used to measure waist circumference. Participants will report their current pants size. Values are: 00-0 = extra small, 2-4 = small, 6-8 = medium, 10-12 = large,14-16 = extra large, 18-20 = 2XL, 22-24 =3XL. Higher scores indicate higher waist circumference.	baseline (T1) and 3 weeks follow up (T2)

Values are:1 = never, 2 = less than once per month,3 = 1-3 times per week, 4 = 3-4 times per week,5 = 5-6 times per week, 6 = 1 time per day, 7 = 2 or more times per day. Higher scores indicate more frequent fat intake.	baseline (T1) and 3 weeks follow up (T2)
Secondary	Change in fruit and vegetable intake	The NCI brief fruit and vegetable intake survey (9 items) will be used to measure fruit and vegetable intake. Participants will be asked to report frequency of each specific fruit and vegetable that they eat over the past month. Values are:1 = never, 2 = 1-3 times last month,3 = 1-2 times per week, 4 = 3-4 times per week, 5 = 5-6 times per week, 6 = 1 time per day, 7 = 2 times per day, 8 = 3 times per day, 9 = 4 times per day, 10 = 5 or more times per day. Higher scores indicate more frequent fruit and vegetable intake.	baseline (T1) and 3 weeks follow up (T2)
