This study analyzed the intervention cost of a novel early childhood obesity prevention program -- Preventing Childhood Obesity Through a Mindfulness-Based Parent Stress Intervention (PMH+N) conducted by Yale Stress Center. The randomized clinical trial started from 11/01/2018 and will enroll 240 participants in total. Parents were included in the trial if they had: a child in the 2- to 5-year age group, a body mass index (BMI) over 28 kg/m2, high levels of perceived stress as assessed by the Perceived Stress Scale (PSS) (score >25) and were able to read and write in English. For 12 weeks, about 13 parents in the PMH+N group meet weekly in a group setting for 2 hours with approximately 1.5 hours spent on stress reduction and mindfulness (PMH) and 30 minutes on nutrition and physical activity counselling(N). The control group (C+N) also includes approximately13 parents in each group and meets weekly for 12 weeks. To approximately match the contact time of the PMH+N group, the C+N sessions include about 1.5-hour of watching a relaxing video, and 30-minute on nutrition and physical activity counselling which is same as the PMH+N group. The cost analysis included the cost of all materials, services, and other resources that would be needed to implement or replicate the intervention. The total intervention cost was approximately $238,153 (95% UI, $190,204-$300,552) for the PMH+N group and $215,767 (95% UI, $174,243-$273,143) for the C+N group. The cost per person is $1,985 (95 UI, $1,585-$2,505) for the PMH+N intervention and $1,798 (95%UI, $1,452-$2,276) for the C+N intervention. The incremental cost of PMH+N compared with C+N is $22,386 (95% UI, -$14-$55,047) in total and $187 (95% UI, $0-$459) per person.
