Maternal predictors of infant beverage consumption: results from the Nurture cohort study.

OBJECTIVE: The goal of the present study was to estimate prevalence and maternal risk factors for infant beverage consumption. DESIGN: Observational birth cohort. SETTING: Central North Carolina, USA. PARTICIPANTS: Mothers 20-36 weeks pregnant were surveyed every 3 months through their infant's first year (n 666) on their sociodemographics and infant's consumption frequency of 100 % fruit and vegetable juices and sugar-sweetened-beverages (SSB). Repeated-measure models, using a compound symmetry covariance structure, were used to assess the association of sociodemographic and maternal predictors with introducing juice and SSB separately and explored interaction terms with time to determine how the effects of the predictors change over time. RESULTS: On average, mothers were 28 years old, 72 % were non-Hispanic Black and 59 % were low-income. We found time by race, income, education, maternal age and breast-feeding duration interactions for both juice and SSB consumption. At approximately 6-7 months of age through 12 months of age, being Black, having a lower income (≤$US 20 000 v. >$US 20 000 per year) and education (less than high-school degree v. high-school degree or higher), being younger (<26 years v. ≥26 years) and breast-feeding for fewer than 26 weeks were each associated with introduction of both juice and SSB consumption. CONCLUSIONS: Future efforts are needed to raise awareness on the importance of national recommendations of limiting juice and SSB for infants, together with decreasing disparities in unhealthy beverage intake early in life.
