Background: Stress and obesity are interrelated and common among low-income adults. Mind-body interventions have been shown to reduce psychological distress and have been incorporated into many weight loss interventions. However, few of these programs have incorporated a telephone coaching component.
Objective: We designed and piloted a novel weight loss telephone coaching intervention for this population and examined its effectiveness on weight loss and improvements in health behaviors in obese community health center patients.
Methods: This was a 6-month, single-arm, prospective, pre-post pilot study. The study took place at a community health center near Boston, Massachusetts. Participants were 27 overweight and obese community health center patients. The intervention consisted of one in-person intake with the registered dietitian, trained in mind-body approaches, and approximately 1 phone coaching session every 2 weeks for 6 consecutive months. Anthropometric data consisted of weight, body mass index (BMI), and blood pressure. Questionnaires consisted of the Perceived Stress Scale-10 item, the CIGNA Healthy Eating Survey, Section H: Behavioral Eating, a physical activity questionnaire, and a nutritional habits questionnaire. We used paired samples t tests to assess pre-post changes in weight, BMI, blood pressure, perceived stress, behavioral eating, and physical activity. We also conducted semistructured exit interviews to learn about participants' experiences in this program.
Results: There was a trend toward weight reduction (P < .1, Cohen's d = 0.33) and significant improvements in systolic blood pressure (P = .001, Cohen's d = 0.72), perceived stress (P = .001, Cohen's d = 0.75), and behavioral eating (P = .009, Cohen's d = 0.54). Improvements in weight were sustained 6 months after completion of the intervention.
Conclusion: Results suggest that a telephone nutrition health coaching intervention is feasible and may facilitate weight loss in obese community health center patients. Future randomized-controlled studies are warranted to better understand these improvements.
