Insights
Mothers of infants with congenital heart defects (CHD) wean earlier, especially those with comorbidities. However, continued breastfeeding rates remain significant, highlighting the need for further research into supportive factors for these infants.
Area of Science:
- Pediatrics
- Cardiology
- Public Health
Background:
- Congenital heart defects (CHD) affect infant feeding practices.
- Breast milk feeding (BMF) offers numerous benefits for infant health.
- Understanding BMF in infants with CHD is crucial for optimizing care.
Purpose of the Study:
- To determine the prevalence of BMF in infants with CHD during the first six months of life.
- To compare BMF rates in infants with CHD to the general population.
- To investigate the impact of comorbidities on BMF in infants with CHD.
Main Methods:
- Utilized data from the Norwegian Mother and Child Cohort Study.
- Included 131 infants with moderate/severe CHD and 65 with comorbidities.
- Analyzed feeding status using Cox regression analyses.
Main Results:
- Mothers of infants with CHD had a 1.69 HR of weaning compared to controls.
- Mothers of infants with CHD and comorbidities had a 3.54 HR of weaning.
- At 6 months, 9.9% of infants with CHD were predominantly breastfed, 64.1% continued, and 26% received none.
Conclusions:
- CHD and comorbidities increase the risk of earlier weaning.
- Continued breastfeeding rates are relatively high despite increased weaning risk.
- Further research is needed to identify factors supporting BMF in infants with CHD.
Objective:
To explore the prevalence of breast milk feeding (BMF) of infants with congenital heart defects (CHD) during first 6 months of life, as compared with general population.
Design:
The study is based on a subsample of the Norwegian Mother and Child Cohort Study conducted by Norwegian Institute of Public Health. A total of 60,600 mothers completed a questionnaire about infant feeding at 6 months postpartum. Infants with moderate/severe CHD (n = 131) were identified using nationwide CHD registry. A group of infants with CHD with comorbidity was also defined (n = 65). BMF was classified as predominant, continued, or no BMF. Month to month feeding status was analysed by means of Cox regression analyses.
Results:
Between child age 2-6 months, mothers of infants with CHD had a hazard ratio (HR) of 1.69 of weaning their child compared with mothers of controls. Mothers of infants with CHD with comorbidity weaned at an even faster rate (HR 3.54). At age 6 months, 9.9% of infants with CHD were fed with breast milk predominately, 64.1% continued to receive breast milk, and only 26% were fed no breast milk. For infants with CHD with comorbidity, corresponding percentages were 7.7%, 43.1% and 49.2%, respectively.
Conclusions:
Although CHD alone and particularly CHD with comorbidity increased risk that mothers wean earlier, a relatively high rate of continued breastfeeding was maintained. Future studies should investigate factors that support continued BMF even in the most severely affected children with CHD.
