Investigating the Effect of Supportive Interventions on Initiation of Breastfeeding, Exclusive Breastfeeding, and Continuation of Breastfeeding in Adolescent Mothers: A Systematic Review and Meta-Analysis.

The initiation of breastfeeding, exclusive breastfeeding, and its duration for 2 years in adolescent mothers is less than adult mothers. The purpose of this study is to determine the effect of supportive interventions on the initiation of breastfeeding, exclusive breastfeeding, and continuation of breastfeeding in adolescent mothers. Web of Science, PubMed, Scopus, Cochrane Library, EMBASE, ProQuest, SID, Iranmedex, and Google Scholar were searched to find English and Persian clinical trial studies without time limit. The Cochrane checklist was used to check the bias of the articles. Data analysis was done using STATA version 11. I-squared index was used to check the heterogeneity, and funnel plot and Begg test were used to examine the publication bias. The combined odds ratio (OR) and random effects model were used to combine the studies and perform meta-analysis. Of 492 articles, 11 articles were entered to the systematic review. Of 11 articles, three articles were entered to the meta-analysis. The supportive interventions included educational and counseling interventions, home visit, and peer support. The results of the present random effects meta-analysis model showed that the combined OR was 3.38 with 95% confidence interval (1.66-6.88,  = 0.001), thus that, breastfeeding initiation in the intervention group was higher than the control group. Supportive interventions such as educational and counseling interventions, home visits, and peer support are suitable strategies to promote breastfeeding in adolescent mothers. Therefore, it is suggested to integrate these strategies in prenatal and postpartum care of adolescent mothers.
