The Use of Early Fortification in Preterm Infants

October 1, 2026 updated by: Putri Maharani Tristanita Marsubrin, MD, PhD, Universitas Indonesia

Early Fortification to Shorten Birth Weight Recovery Time in Very Preterm or Very Low Birth Weight Infants

Very premature or very low birth weight (VLBW) infants are at risk of suboptimal growth after birth, making adequate nutrition essential. Breast milk alone is insufficient to meet the nutritional needs of premature infants, so fortification is added to breast milk to support catch-up growth. Standard human milk fortification (HMF) is typically started when the feeding volume reaches 100 ml/kg/day, but research suggests that early HMF administration can increase protein intake sooner without negative effects on the infant. Early HMF administration didn't increase the incidence of food intolerance and necrotizing enterocolitis (NEC). Other studies have shown that early fortification increases the rate of early weight gain without increasing the incidence of complications. There is no research in Indonesia comparing the duration of regaining birth weight between early HMF and standard HMF. This study aims to determine the difference in the duration of regaining birth weight in very premature or VLBW infants given early HMF versus standard HMF. The research method is a prospective, randomized, double-blind preliminary study comparing early HMF administration (when feeding volume reached 30 ml/kg/day) with standard HMF (when feeding volume reached 100 ml/kg/day).

  • Infants who had already achieved return to birth weight (RTBW) before initiation of the intervention
  • Infants with insufficient breast milk availability to provide ≥50% of their daily enteral requirements before enrollment
  • Infants born to mothers with medical conditions that precluded breastfeeding
  • Infants with known cow's milk protein allergy before initiation of the intervention
  • Infants who died before initiation of the intervention

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Early Fortification Group

Participants were given early fortification when the feeding volume reached 30 ml/kg/day

In the early fortification group, 1 sachet of HMF was added to 30 ml of breast milk for the first 24 hours. If the feeding tolerance was good, 1 sachet of HMF was then mixed into 25 ml of breast milk.

Experimental: Standard Fortification Group

Participants were given standard fortification when the feeding volume reached 100 ml/kg/day

In the standard fortification group, 1 sachet of HMF was mixed into 25 ml of breast milk starting from the first day of HMF administration.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Return to birth weight
Time Frame: Body weight will be measured daily from birth until the day the infant first reaches their birth weight. The assessment period is expected to last up to 3 weeks after birth.

The first day the infants reached their birth weight again

Body weight will be measured daily from birth until the day the infant first reaches their birth weight. The assessment period is expected to last up to 3 weeks after birth.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants with Feeding Intolerance
Time Frame: Feeding intolerance will be monitored from the initiation of HMF administration until the day the infant first reaches their birth weight. The monitoring period is expected to last up to 3 weeks after birth.

Feeding intolerance was defined as inability to tolerate enteral feeding, characterized by a gastric residual volume greater than 50% (with or without regurgitation), vomiting, abdominal distension, decreased frequency of bowel movements, and disruption of the feeding plan.

Feeding intolerance will be monitored from the initiation of HMF administration until the day the infant first reaches their birth weight. The monitoring period is expected to last up to 3 weeks after birth.
Number of Participants with Electrolyte Imbalances
Time Frame: Electrolytes will be assessed once during intervention. Blood sampling will be scheduled by the attending physician. The intervention period starts with HMF administration and ends when birth weight is regained, expected within 3 weeks after birth.

Electrolyte imbalance was identified when serum levels fell below institutional laboratory reference ranges, with assessments performed for all study subjects.

Electrolytes will be assessed once during intervention. Blood sampling will be scheduled by the attending physician. The intervention period starts with HMF administration and ends when birth weight is regained, expected within 3 weeks after birth.
Number of Participants with Necrotizing Enterocolitis
Time Frame: Necrotizing enterocolitis will be monitored from the initiation of HMF administration until the day the infant first reaches their birth weight. The monitoring period is expected to last up to 3 weeks after birth.

Necrotizing enterocolitis was defined as a disorder of the intestinal mucosa, clinically manifested by feeding intolerance, bloody stools, and possibly accompanied by changes in abdominal skin color, supported by abdominal X-ray findings consistent with necrotizing enterocolitis.

Necrotizing enterocolitis will be monitored from the initiation of HMF administration until the day the infant first reaches their birth weight. The monitoring period is expected to last up to 3 weeks after birth.
