The effect of mother-infant skin-to-skin contact immediately after birth on exclusive breastfeeding: a systematic review and meta-analysis

In the new millennium, exclusive breastfeeding plays an important role in national and international policies. The effects of mother-infant skin-to-skin contact (SSC) after birth has been investigated in several studies. Given that there has been no overall estimate of this effects, the present study was conducted with the aim of investigating the effects of mother-infant SSC on the rate of exclusive breastfeeding through a systematic review and meta-analysis of randomized controlled trials. In the present study, the databases of Scopus, PubMed, Cochrane, SID, Magiran, IranDoc, and Google Scholar were searched to identify randomized controlled trials that evaluated the effects of mother-infant SSC immediately after birth on the rate of exclusive breastfeeding. The risk of bias and strength of evidence were examined according to the Cochrane Collaboration’s tool and the Grading of Recommendation, Assessment, Development, and Evaluation approach, respectively. The data analysis was performed using Stata software. To assess the publication bias and heterogeneity, Egger’s and Begg’s tests and I2 were used, respectively. In addition, the fixed effects model was employed to perform the meta-analysis. The heterogeneity of the factor of effects in the studies was determined as 16.2% (p
