Infant Appetite Traits and Early Infant Feeding Practices in Low-Income Hispanic Families

Abstract

Objectives: This study examined the association of infant appetite traits and exclusive breastfeeding (EBF), BF intensity, early introduction of complementary foods/liquids and 100% fruit juice consumption among Hispanic infants during the first year of life. Methods: This study is a cross-sectional analysis of data collected from the "Starting Early Program" randomized controlled obesity prevention trial of low-income, Hispanic mother-child pairs (n = 533). Four infant appetite traits including Food Responsiveness (FR), Enjoyment of Food (EF), Satiety Responsiveness (SR), and Slowness in Eating (SE) were assessed using the Baby Eating Behavior Questionnaire. Each appetite trait was based on a 5-point Likert frequency scale. Infant feeding measures were collected using 24-hour recall methodology and survey based on the Infant Feeding Practices Study II. Linear and logistic regressions assessed the associations between appetite traits and infant feeding practices, specifically 1) EBF, 2) BF intensity (% of daily milk consumption that is breast milk), 3) early introduction to complementary foods/liquids defined as receiving prior to infant age 4 months, and 4) Any 100% fruit juice consumption at age 10 months. Results: Of the 473 children with both appetite and infant feeding measures, 48% were male with mean birth weight of 3.4 kg. After adjusting for confounders, infants with higher SE scores had higher odds of EBF duration (≥3 months) (OR = 1.7, P < 0.001), and higher odds of having medium (20% ≤ score ≤ 80%) and high (>80%) BF intensity (OR = 1.8, P = 0.002; OR = 2.5, P < 0.001), compared to infants with lower SE scores. Infants with higher SE and SR were less likely to receive early complementary foods/liquids (OR = 0.59, P = 0.026; OR = 0.51, P = 0.009). Infants with higher EF were more likely to consume any 100% fruit juice at age 10 months (OR = 1.7, P = 0.047). The other appetite traits were not significantly related to infant feeding measures. Conclusions: Higher SE was associated with greater EBF and BF intensity. Infants with higher SE and SR were less likely to have early introduction to complementary foods/liquids. Infants with higher EF were more likely to have juice at 10 months. Appetite traits are associated with potentially obesogenic feeding practices and may represent a target for early life infant feeding interventions.
