Insights
Breastfeeding initiation among Neonatal Intensive Care Unit (NICU) infants in Ohio increased from 2006 to 2012. This trend was observed across all gestational ages, with preterm infants showing higher rates in later years.
Area of Science:
- Neonatal care
- Public health
- Infant nutrition
Background:
- Breastfeeding rates are rising nationally, but trends for infants in Neonatal Intensive Care Units (NICUs) are less understood.
- NICU admissions represent a significant portion of newborn care, making breastfeeding trends within this population crucial.
Purpose of the Study:
- To analyze breastfeeding initiation trends among Ohio NICU infants from 2006 to 2012.
- To investigate how these trends differ based on infant gestational age.
Main Methods:
- Utilized Ohio Vital Statistics birth certificate data for analysis.
- Employed Cochran-Armitage test for trend analysis and logistic regression to assess associations between breastfeeding and gestational age over time.
Main Results:
- Observed a significant increase in breastfeeding initiation among NICU infants, from 53.3% in 2006 to 63.8% in 2012 (p < 0.01).
- Found increasing breastfeeding trends across all gestational age categories during the study period.
- In 2011-2012, preterm infants were more likely to receive breast milk in the NICU compared to term infants.
Conclusions:
- The disparity in breastfeeding initiation between NICU-admitted and non-admitted infants is narrowing, especially for extremely premature infants.
- Despite encouraging trends for premature infants, a substantial percentage of mothers of term NICU infants still do not initiate breastfeeding.
- There is a need for enhanced, targeted education and support for mothers of infants admitted to the NICU.
Background:
While breastfeeding in the United States is on the rise, trends among infants admitted to the Neonatal Intensive Care Unit (NICU) are less known. The objective of this study was to examine trends in breastfeeding initiation among NICU-admitted infants in Ohio from 2006 to 2012 and to determine differences in breastfeeding initiation trends by gestational age.
Methods:
Using Ohio Vital Statistics birth certificate data, the Cochran-Armitage test for trend was used to determine significant trends in breastfeeding by gestational age. Logistic regression was used to examine the association between breastfeeding initiation and gestational age by year.
Results:
From 2006 to 2012, 48,758 infants born in Ohio were admitted to the NICU, representing 5.6 percent of all newborns. Breastfeeding among NICU-admitted infants increased from 53.3 percent in 2006 to 63.8 percent in 2012 (p < 0.01). Increasing, significant trends in breastfeeding were also observed within each gestational age category over the 7 years. In 2011 and 2012, preterm infants were significantly more likely than term infants to be fed breastmilk in the NICU.
Discussion:
The gap between breastfeeding initiation among NICU-admitted and non-admitted infants appears to be narrowing, particularly for the most extreme gestational ages. While these increasing trends in breastfeeding among the most premature infants are encouraging, nearly 40 percent of mothers of term infants admitted to the NICU, the largest proportion of the NICU population, are still not initiating breastfeeding. More education and support specific to mothers of infants admitted to the NICU is needed.
