Research about skin-to-skin care (SSC) experiences in early period after birth has focused on mothers and infants. The purpose of this study was to determine the outcomes of paternal skin-to-skin care (P-SSC) in both fathers and infants. The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed/MEDLINE, Embase, CINAHL, PsycInfo, Airiti Library, and Google Scholar were searched for randomized controlled trials (RCTs) that reported outcomes of P-SSC in both fathers and infants. We calculated pooled mean differences (MDs) and 95% confidence intervals (CIs) using RevMan 5.3 for the meta-analysis [PROSPERO: CRD42018106790]. Seven RCTs including a total of 552 participants were eligible for inclusion. Compared to the maternal skin-to-skin care (M-SSC), fathers in the P-SSC exhibited no significant differences in salivary oxytocin levels (MD: -0.35 pg/mL; 95% CI: -0.75, 0.05), salivary cortisol levels (MD: 0.25 μg/dL; 95% CI: -0.82, 1.33), or anxiety scores (MD: -0.17; 95% CI: -0.57, 0.22) during the period of SSC. Similarly, there were no significant differences in the salivary cortisol levels (MD: -0.11 μg/dL; 95% CI: -0.05, 0.28) among preterm infants between the 2 groups. However, the crying time was less among full-term infants in the P-SSC group compared with infants in the incubator care or cot care groups. P-SSC had similar effects as M-SSC on stress-related outcomes during and after SSC among fathers and infants in the early stages after birth. We recommend that P-SSC be implemented in the early stages after birth. Further RCTs with a longitudinal design and large samples are needed to better understand the long-term effects of P-SSC on fathers and infants.
