Key Takeaway
Note that an exclusive human milk diet is associated with lower odds of death before discharge in premature infants.

This systematic review and meta-analysis evaluated the impact of an exclusive human milk diet (EHMD), including human milk-derived fortifiers, compared to diets containing cow milk-derived products in 4,713 premature and very low birthweight infants. The primary outcome was survival to hospital discharge.

The pooled analysis indicated that infants on an EHMD had lower odds of death before discharge (OR 0.80; 95% CI 0.65 to 0.98; p = 0.03). This finding was directionally consistent across both randomized studies (OR 0.62) and non-randomized studies (OR 0.82).

Several limitations were noted by the authors. No significant differences emerged within the randomized study subgroup or the non-randomized study subgroup. Furthermore, no significant difference was observed between groups in the two specific randomized trials that directly compared human milk-derived and cow milk-derived fortifiers.

The consistent direction of effect across different study designs suggests a potentially clinically meaningful association for infants with prematurity and low birthweight. However, the lack of significance in specific subgroup analyses requires cautious interpretation regarding the strength of the evidence for specific dietary components.

How this fits prior evidence

This meta-analysis addresses a gap in nutritional management for premature infants by evaluating the impact of exclusive human milk diets on survival. While previous coverage focused on telemedicine family care guidance to improve neurodevelopmental outcomes, this finding provides evidence regarding mortality risks associated with early nutrition and cow milk exposure.

Researchers looked at data from 4,713 infants who were born prematurely or with very low birth weight. They compared the outcomes for babies fed an exclusive human milk diet, which included milk-derived fortifiers, against those who received diets containing cow milk products.

The analysis found that infants on a human milk diet had lower odds of dying before being discharged from the hospital. This trend was consistent across both randomized and non-randomized studies. While the overall data suggests a potential benefit for these vulnerable babies, some specific parts of the study were less clear.

It is important to note that when researchers looked only at randomized trials or specifically at cow milk versus human milk fortifiers, they did not find significant differences. Because this was a broad review of many different types of studies, the results show an association rather than a proven cause. Parents and doctors should discuss these findings with medical teams to determine the best nutrition plan for their specific situation.

What this means for you:
An exclusive human milk diet is linked to lower odds of death for premature infants in large pooled analyses.

Common questions

Does a human milk diet help premature babies survive?

The study found that infants on an exclusive human milk diet had lower odds of death before hospital discharge. This finding was consistent across both randomized and non-randomized studies in the analysis. However, because this is a pooled analysis of many studies, it shows a link rather than a guaranteed result for every infant.

Is there a difference between human milk and cow milk fortifiers?

When researchers looked specifically at the two randomized trials that directly compared human milk-derived fortifiers to cow milk-derived fortifiers, they did not find a significant difference. The overall benefit was seen more clearly when looking at all study types combined in one large group.

Who is this finding most relevant for?

This research specifically looked at infants who were born prematurely or with very low birth weight (VLBW). These babies are particularly vulnerable during their first weeks of life. You should talk to a neonatologist or pediatric specialist to discuss how these findings apply to your baby's specific needs.

BackgroundSurvival to hospital discharge remains a critical outcome for premature and very low birthweight infants (VLBW), who often require fortification of human milk to meet nutritional needs within tolerated feeding volumes. Although exclusive human milk diets (EHMD) that include human milk-derived fortifiers have been proposed as an alternative to cow milk-derived fortification or formula supplementation, evidence for their association with improved survival remains inconsistent across studies.ObjectiveTo evaluate the association between an EHMD and survival to hospital discharge among premature and low birthweight infants, synthesizing evidence from randomized and non-randomized studies.MethodsPubMed, Scopus, and Web of Science were searched through July 2025 for studies comparing an EHMD (human milk fortified with human milk-derived fortifier) with diets containing cow milk-derived products. Two reviewers independently screened studies, extracted data, and assessed risk of bias. Pooled odds ratios (OR) were calculated using random-effects meta-analysis, with subgroup analyses by study design.ResultsFive randomized and 9 non-randomized studies were included, encompassing 4,713 infants born between 2004 and 2021. Mean birthweights ranged from 741 to 1,361 g, and mean gestational ages ranged from 25.5 to 29.7 weeks. In pooled analyses, EHMD was associated with lower odds of death before discharge (pooled OR 0.80, 95% CI 0.65–0.98; I2 = 0%, tau2 = 0.00, p = 0.03). Directionally similar associations were observed in randomized (OR 0.62, 95% CI 0.28–1.38) and non-randomized studies (OR 0.82, 95% CI 0.66–1.03), although no significant differences emerged within either subgroup. In the two randomized trials directly comparing human milk-derived and cow milk-derived fortifiers, mortality estimates were directionally similar but no significant difference was observed between groups.ConclusionEHMD was associated with lower odds of death before discharge in pooled analyses. Although no significant differences emerged in the subgroup analyses, the consistency in effect direction across study designs supports the possibility of a clinically meaningful association. Adequately powered randomized and pragmatic trials are needed to confirm this association.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420251059764, PROSPERO: CRD420251059764
