DescriptionStatement of Problem: The global prevalence of obesity has been increasing in infants. There is evidence to support that breastfeeding is a protective factor against obesity as it promotes higher maternal sensitivity to infant hunger and satiety cues. Formula feeding has been associated with lessened maternal sensitivity, higher instances of overfeeding, as well as rapid weight gain.Objective: The purpose of this study was to determine if maternal feeding sensitivity was related to energy intake and weight-for-length status in infants. Based on the literature review, it was predicted that mothers who displayed lower levels of maternal sensitivity would have infants who have a higher energy intake, resulting in a higher weight-for-length category
Methods: A secondary data analysis was performed to examine any correlation between maternal sensitivity and feeding outcomes in the infant’s first year of life. Participants from WIC were recruited, and two-day home visits were conducted at three different time points. On the first day, interviews were conducted in which mothers were asked about feeding practices, infant activity, and fussiness. Diet recalls were also filled out by the mothers. On the second day, a trained research assistant weighed and measured the infant. The mother and the infant were observed during a feeding session and the behaviors of both were recorded using NCAST feeding scales.
Results: No significant correlations between NCAST scores and kcal intake at 6-months were found. However, higher NCAST infant responsiveness at 6-months predicted lower caloric intake at 12-months. Infant weight-for-length percentile at 6-months was the only variable that was significantly predictive of infant weight for length percentile at 12-months.
Conclusions: In the present study, maternal sensitivity did not play a significant role in predicting weight gain during the first year of life. Instead, higher infant responsiveness was associated with lower caloric intake. Infant weight-for-length percentile at 6 months was the only predictor of weight-for-length at 12 months. Apart from maternal sensitivity, the contribution of the infant should be given added credence when examining the factors that play a role in rapid infant weight gain during the first year of life.
