The home environment and its relation to bottle feeding outcomes in the first year of life

Background: The home environment and caregiver interactions have an impact on infant development. However, there is a paucity of research surrounding the home environment and its relation to early feed-ing outcomes within the first year of life. Therefore, the aim of this study was to examine the relationship between the home environment and infant bottle feeding outcomes at 3 and 12 months of age. Methods: Seventy-two full-term infants completed this study at 3 months of age and fifty-five infants completed the study at 12 months. Data in the current study were collected from a larger, ongoing study completed in the infant's home at 3 and 12 months of age. The Infant-Toddler Home Observation for Measurement of Environment Inventory (IT-HOME) was utilized to assess the infant's home environment. The Oral Feeding Skills (OFS) scale was completed while the infant was observed during a bottle feed. Caregivers completed a questionnaire about their infant's feeding abilities via the Neonatal Eating Assess-ment Tool (Neo-EAT) at 3 months and Pediatric Eating Assessment Tool (Pedi-EAT) at 12 months. Results: At 3 months of age, the IT-HOME Involvement subscale was associated with an increase in the amount of milk provided in the infant's bottle. There were no significant associations between the IT -HOME and caregiver report of feeding at 3 months of age. At 12 months of age, the IT-HOME Acceptance subscale was associated with an increase in oral transfer rate and the IT-HOME Variety subscale was associated with a decrease in oral transfer rate. Additionally, the IT-HOME Organization subscale was as-sociated with caregiver report of feeding on the following Pedi-EAT scales: Mealtime Behaviors, Selective Restrictive Eating, and Oral Processing at 12 months. Conclusions: These findings reveal that the home environment is significantly related to different infant bottle feeding outcomes over the first year of life. At 3 months, IT-HOME Involvement was associated with the amount of milk offered in the bottle, whereas at 12 months of age, subscales of the IT-HOME were associated with oral feeding transfer rate and caregiver report of feeding. Clinically, these findings point to the importance of considering the infant's bottle feeding skills in conjunction with certain aspect within the infant's environment. Additional research is needed to further explore these relationships in greater detail, with a larger sample size and across patient populations. (c) 2022 Elsevier Ltd. All rights reserved.
