This research was conducted for investigating the impact of delivery mode and maternal postpartum functional state on breastfeeding self-sufficiency.Material and methods: Data of this research featuring crosssectional design were collected between November 2018 and February 2019. Size of the sampling performed with Power analysis was calculated as 444 puerperants with a confidence interval at 97% and population representation at 80%. Data were collected by Personal Information Form, Barkin Index of Maternal Functioning (BIMF) and Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). ANOVA, t test in independent groups and Pearson Correlation analysis as well as descriptive analyses were used in the analysis of data.Results: The age average of puerperants is 26.97±5.79, it was found out that 34.9% of puerperants are secondary school graduates, 80.6% do not work, 71.6% have a moderate economic state and 77.0% have an elementary family type. The delivery mode of 59.2% of the puerperants is cesarean and no statistically significant relation is found between the delivery mode and breastfeeding self-sufficiency (p>0.05). Total score average of puerperants taken from BIMF is 72.82±10.59. Total score averages taken from the sub-dimensions of BIMF are 10.65±3.08 in the sub-dimension of "self-care"; 9.25±1.73 in the sub-dimension of "mother's psychology"; 19.86±3.00 in the sub-dimension of "baby-care"; 13.36±2.93 in the sub-dimension of "social support" and 19.69±3.57 in the subdimension of "adaptation to motherhood". Total score averages which mothers took in BSES-SF are 56.17±8.54. It was determined that there is a statistically significant weak relation between BIMF and each of its subdimensions and BSES-SF in positive way and as the maternity function of puerperants increases, the breastfeeding self-sufficiency also increases at significant level (p<0.001).
Conclusion:While there is no significant relation between the delivery mode and breastfeeding self-sufficiency of puerperants, it is found out that the maternity function of puerperants increases, the breastfeeding self-sufficiency also increases.
