Maternal Mindfulness Is Associated With Lower Child Body Mass Index Z Score.

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 (ß = -.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.

Predictors of nutritional adequacy in mother-toddler dyads from rural families with limited incomes.

OBJECTIVE: To predict the mean adequacy ratio (MAR) scores of mothers and toddlers from intakes of fruits, vegetables, and dairy group foods and being seated during mealtimes. DESIGN/SUBJECTS: This was a regression analysis of cross-sectional data of the diet quality and being seated during mealtimes of 100 rural mother-toddler dyads from limited-income families using two 24-hour dietary recalls. Children were 11 to 25 months of age and at or below 100% of the poverty index. MEASURES OF OUTCOME: Dietary quality for mothers and toddlers was assessed using a MAR score for eight different nutrients (vitamin A, vitamin C, vitamin D, folate, calcium, zinc, iron, and magnesium), and a score of 85 or above was considered nutritionally adequate. The main food groups of interest were servings from the fruits, vegetables, and dairy group foods. Mealtime sitting behavior was the percentage of times the toddler remained seated while eating. RESULTS: Servings of fruits, vegetables, and dairy foods predicted 0.62 of the variance in the mother's MAR score, whereas vegetable and dairy intakes along with being seated while eating indicated nutritional adequacy for toddlers. Mothers with low MAR scores were most likely to have toddlers with poor diets, although few toddlers had poor diet quality. CONCLUSIONS: Adequate intakes of dairy, vegetables, and whole fruits along with being seated while eating could be quick assessment tools to screen toddlers for nutritional risk. Mothers with poor diet quality were likely to have toddlers with poor diets; low intakes of fruits, vegetables, and dairy foods were markers for poor diet quality in mothers.
