Delayed Breastfeeding Initiation Is Associated with Infant Morbidity

Area of Science:

• Pediatrics
• Public Health
• Global Health

Background:

• Breastfeeding initiation timing is a critical factor in infant health outcomes.
• Understanding the impact of delayed breastfeeding on mortality, morbidity, and growth is essential for public health interventions.

Purpose of the Study:

• To investigate the association between the timing of breastfeeding initiation and postneonatal mortality, morbidity, and infant growth up to 24 months.
• To analyze the risks of infectious diseases and growth failure in relation to early versus delayed breastfeeding in Tanzanian infants.

Main Methods:

• A cohort of 4203 infants from two micronutrient supplementation trials was analyzed.
• Cox proportional hazards models and general estimating equations were used to determine relative risks.

Main Results:

• Delayed breastfeeding initiation (>1 hour after birth) was observed in 13% of infants.
• No association was found between breastfeeding initiation time and mortality or infant growth failure up to 2 years.
• Delayed initiation was linked to increased risks of upper respiratory infection symptoms, vomiting, cough, and difficulty breathing in the first six months.

Conclusions:

• Delayed breastfeeding initiation is associated with higher infant morbidity, particularly respiratory infections, in the initial six months of life.
• Prioritizing early, exclusive, and prolonged breastfeeding is recommended to enhance child health outcomes.
