Grandparent Coresidence and Risk of Early Child Overweight and Obesity in Low-Income, Hispanic Families in New York City

Abstract

ObjectiveChildren in low-income Hispanic families are at high risk of obesity and are more likely to live with grandparents than their non-Hispanic white counterparts. We aimed to determine if grandparent coresidence (prenatal through age 2 years) was associated with: 1) obesogenic feeding practices; and 2) child weight outcomes from birth to three years. MethodsWe analyzed data from 267 low-income, Hispanic mother-infant pairs in the control group of an obesity prevention trial in New York City. Linear and logistic regression tested differences in obesogenic feeding practices and weight outcomes at 2 and 3 years, dependent upon grandparent coresidence. Multilevel modeling tested associations between grandparent coresidence and WFAz over time. ResultsPersistent grandparent coresidence (vs none) was associated with putting cereal in the bottle (adjusted odds ratio [aOR] 3.46; 95% confidence interval [CI] 1.43, 8.40). Persistent grandparent coresidence (vs none) was associated with higher mean WFAz (2 years: B 0.83; 95% CI 0.41, 1.25; 3 years: B 0.79; 95% CI 0.32, 1.25) and higher odds of child overweight/obesity risk (2 years: aOR 4.38; 95% CI 1.64, 11.69; 3 years: aOR 3.15; 95% CI 1.19, 8.36). In multilevel models, more occasions of grandparent coresidence were associated with higher WFAz. ConclusionsGrandparent coresidence may be associated with higher risk of child overweight/obesity in low-income, Hispanic families. Further research is needed to elucidate mechanisms of these associations and to inform obesity prevention strategies in the context of multigenerational families.
