Does kangaroo care improve outcomes for preterm infants?

Does kangaroo care actually improve survival and physical health for preterm infants?

Yes, and the evidence is strong and consistent. A 2025 randomized controlled trial of 240 preterm infants with respiratory distress syndrome found that kangaroo mother care (KMC) improved 28-day survival by 58% (hazard ratio 0.42) and reduced hospital-acquired infections by 55% [1]. Infants in the KMC group also needed breathing support for 2.2 fewer days and were more likely to be exclusively breastfed at discharge (74% vs. 48%) [1]. These results are backed by a 2023 meta-analysis of 31 trials including over 15,500 infants, which found that KMC reduced the risk of death during hospitalization or the first 28 days by 32% (relative risk 0.68) and probably reduced severe infections by 15% (relative risk 0.85) [2]. The meta-analysis also showed that starting KMC within 24 hours of birth and providing it for at least 8 hours daily gave the greatest benefits [2].

Kangaroo care also helps with specific medical issues. A 2023 randomized trial found that KMC reduced feeding intolerance in preterm infants, shortening the time to full enteral feeding and improving vital signs like oxygen saturation and heart rate [13]. Another study showed that immediate skin-to-skin contact after birth improved cardiorespiratory stability in very preterm infants (28-32 weeks), with a higher stability score compared to standard incubator care [12]. Importantly, a large 2022 observational study of over 3,400 infants found that early skin-to-skin contact did not increase the risk of late-onset sepsis, addressing a common concern among clinicians [7]. A pilot study even suggested that KMC may improve the infant's skin microbiome by increasing beneficial bacteria and reducing potentially harmful ones [10].

Does kangaroo care also help parents' mental health and bonding?

Yes, kangaroo care significantly benefits parents, reducing stress, anxiety, and depression while improving the parent-infant bond. A 2025 randomized clinical trial found that immediate skin-to-skin contact after very preterm birth reduced depression symptoms in mothers and anxiety symptoms in fathers at one week after birth, and these benefits for fathers persisted at the infant's term-equivalent age [14]. A 2023 secondary analysis of the same trial showed that immediate skin-to-skin contact improved mother-infant interaction quality at 4 months, specifically in the infant's positive affect and social skills [6]. Another 2026 randomized trial found that combining kangaroo care with lullaby singing significantly reduced maternal anxiety and improved both mothers' and infants' physiological stability (heart rate, breathing rate, oxygen levels) [8].

Kangaroo care also helps fathers. A 2026 study found that implementing kangaroo care in the NICU significantly reduced post-traumatic stress disorder (PTSD) symptoms, illness uncertainty, and depressive symptoms in fathers of preterm infants [5]. A 2022 pilot study showed that teaching mindfulness exercises to mothers during kangaroo care reduced their stress, anxiety, and depression, with medium to large effects [9]. A 2023 study found that mothers who participated in both stages of the kangaroo care program had higher education levels and were more likely to have a partner, suggesting that support systems can improve adherence [3]. Overall, the evidence shows that kangaroo care is a powerful tool for supporting the whole family, not just the infant.

Are there any risks or limitations to kangaroo care?

The evidence shows kangaroo care is safe for even the most vulnerable preterm infants, with no major risks identified. A 2022 clinical trial found that very preterm infants (28-32 weeks) who received immediate skin-to-skin contact did not develop hypothermia (low body temperature) and actually had fewer episodes of hyperthermia (overheating) compared to standard incubator care [4]. The same trial also found that immediate skin-to-skin contact improved cardiorespiratory stability, not harmed it [12]. A large 2022 observational study specifically addressed the fear that skin-to-skin contact might increase infections, finding no association with late-onset sepsis or any other neonatal infection [7].

However, there are practical limitations. A 2023 study found that about 31% of mother-infant dyads did not participate in any stage of a hospital kangaroo care program, and those who did not had lower education levels, were more often single mothers, or had infants who were sicker [3]. This suggests that while kangaroo care is safe and effective, implementation can be challenging, especially for families with fewer resources or infants requiring intensive medical support. A 2024 study from Pakistan highlighted that socioeconomic factors like maternal anemia and environmental toxin exposure can influence health outcomes, underscoring the need for comprehensive support to ensure all families can benefit [11]. The key takeaway is that the benefits of kangaroo care far outweigh any risks, but healthcare systems need to actively support families to make it happen.
