Associations of parent feeding behaviors and early life food exposures with early childhood appetitive traits in an observational cohort study.

Purpose: Child appetitive traits, eating styles that reflect responsiveness to external influences and internal hunger and satiety signals, are associated with eating behaviors and susceptibility to excess weight gain. However, relatively little is known about early life influences on child appetitive traits. This study investigated relations of early life maternal feeding behaviors and food exposures with appetitive traits at age 3.5 years.

Methods: Participants of the Pregnancy Eating Attributes Study (PEAS) and follow-up study were enrolled in early pregnancy and followed prospectively. This analysis included data collected from baseline through child aged 3.5-years (n = 160). Child appetitive traits at age 3.5 years were measured using the Child Eating Behavior Questionnaire. Age at introduction to fruit, vegetables, discretionary sweets, and discretionary savory foods was assessed, along with intake frequency at infant ages 6, 9, and 12 months, and 2 years. Maternal feeding to soothe was assessed at child aged 3, 6, and 12 months. Maternal permissive feeding was assessed at child aged 2 years. Multiple linear regressions estimated relations of maternal feeding behaviors and infant food exposures with child appetitive traits at age 3.5 years, controlling for sociodemographics and breastfeeding duration.

Results: Maternal feeding to soothe at 6 (r = 0.39, p < 0.001) and 12 months (r = 0.39, p < 0.001) was positively associated with permissive feeding at 2 years. Maternal feeding to soothe at 12 months and permissive feeding at 2 years were associated with greater child emotional overeating, emotional undereating, and desire to drink. Older age at introduction to fruit (β = 0.20±0.08, p = 0.01) and younger age at introduction to discretionary sweet foods (β = -0.07±0.04, p = 0.06) were associated with greater emotional overeating. Older age at introduction to vegetables (β = 0.22±0.11, p = 0.04) and less frequent feeding of fruit (β = -0.20±0.08, p = 0.01) were associated with greater food fussiness.

Conclusions: Associations of emotional eating with parent feeding behaviors and early life food exposures suggest the potential for interventions targeting early life feeding to have long-term impact on child appetitive traits and diet quality.
