Introduction: Nearly a quarter of preschool-aged Chinese American children are overweight or obese. Children of overweight mothers are at higher risk for obesity. Efforts to prevent obesity among low-income minority children with overweight mothers should start in early childhood. Methodology: This randomized pilot study consisted of 8 weekly sessions, examined feasibility of a tablet computer–based intervention among 32 mother–child dyads. The study estimated effect size of the intervention at baseline, 3 and 6 months on maternal outcomes including self-efficacy, eating behaviors, physical activity, child-feeding practices, and change in body mass index. Results: The tablet computer–based intervention is feasible among low-income Chinese mothers with low acculturation. A large-effect size was observed in reducing maternal body mass index, waist circumference, and improving maternal eating style and self-efficacy for promoting healthy eating. Discussion: Multimedia tablet-based education tailored for Chinese immigrant mothers was successful in short-term maternal behaviors changes related to diet and exercise.
