Background: Parental mindfulness may be a novel intervention target for child obesity prevention.

Objective: To examine associations between maternal mindfulness and child body mass index z-score (BMIz).

Methods: In a secondary data analysis of preintervention data from a randomized controlled trial, we assessed survey and anthropometric data from English-speaking mother/child dyads enrolled in Head Start in south central Michigan (n = 105). Surveys included demographic information, child dietary intake, family meal frequency, and the Philadelphia Mindfulness Questionnaire. Multivariable linear regression examined associations between maternal mindfulness and child BMIz, child intake of fruits and vegetables, and frequency of family meals.

Results: Children were M = 53.7 (standard deviation [SD] 7.5) months old, and mothers were M = 31.6 (SD 8.3) years old. The sample of children was 39% white, 26% black, 14% Hispanic, and 35% of children were overweight or obese. Mean maternal BMI was 32.0 (SD 8.3). Greater mindfulness was associated with child BMIz (β = -.02 (SE 0.01), P = .027) adjusting for child race/ethnicity, household food security, maternal education, maternal age, and maternal BMI. Mindfulness was not associated with child fruit intake, child vegetable intake or frequency of family meals. The results were consistent with alternative outcomes of BMI percentile (P = .016) and BMI at the trend level (P = .0595) at the trend level.

Conclusions: Greater maternal mindfulness was associated with lower child BMIz. Future work should consider mechanisms of association. Pediatric providers might consider supporting maternal mindfulness as one element of multicomponent strategies for child obesity prevention.
