Positive communication and warm interpersonal dynamics during family meals are necessary components for family meals to decrease the risk of obesity in children, according to a new study.
“This study identified characteristics of family meals (e.g., interpersonal and food-related dynamics) through direct observational methods that may help explain the inconsistencies found in previous studies regarding the frequency of family meal and childhood obesity status,” Jerica Berge and her colleagues at the University of Minnesota, Minneapolis, reported online (Pediatrics 2014 Oct. 13 [doi:10.1542/peds.2014-1936]).
“Specifically, more positive measures (e.g., group enjoyment, relationship quality, warmth/nurture) were associated with reduced prevalence of child overweight/obesity, and more negative measures (e.g., hostility, indulgent/permissive, inconsistent discipline) were associated with increased prevalence of child overweight/obesity,” they wrote.
For example, the more warmth identified in more family relationships, the less likely it was that a child was overweight or obese, yet higher levels of hostility increased the likelihood of an overweight or obese child, after controlling for age, sex, and race/ethnicity. Findings were similar for family attitudes related to food: Positive food communication correlated with a lower prevalence of overweight/obesity, for example, though some food-related factors were less significant when parents’ body mass index was controlled for.
The researchers used multiple methods to observe the family meals of 120 low-income and/or minority children, average age 9 years, and years in the Minneapolis/St. Paul area over 8 days. Only families who typically ate at least three family dinners a week participated, and half the children were considered overweight (body mass index of 85th percentile or higher).
The researchers video-recorded the meals, inventoried food in the homes, interviewed the participants, and gathered three 24-hour dietary recalls for each child. Then they analyzed positive and negative variables during interactions between each arrangement of two family members over the meals (between the child and each other family member; between caregivers and between each caregiver and sibling).
Positive variables included group enjoyment, relationship quality, communication, parental influence, and positive reinforcement. Negative ones included hostility, lecturing/moralizing, silence, indulgence/permissiveness, inconsistent discipline, and intrusiveness/control.
Overweight/obese children’s family meals lasted an average 13.5 minutes, compared with an average 18.2 minutes for the family meals of the nonoverweight children. Also, 80% of nonoverweight children’s families ate in the kitchen, compared with 55% of overweight/obese children’s families. While only 18% of overweight/obese children had a father/stepfather at the meal, 52% of nonoverweight children did.
