en Midwifery Orginal research <strong><em>Background:</em></strong> There is no substitute to mother breastfeeding; on the one hand, mothers need all-out support, especially in the first days after delivery, which is one of the effective factors for women&rsquo;s success in breastfeeding.<br> <strong><em>Objectives: </em></strong>The aim of this study is to investigate the relationship between social support and early termination of breastfeeding.<br> <strong><em>Methods:</em></strong> This retrospective study examined the degree of social support for mothers embarking on early termination of breastfeeding. It covered a group of 235 individuals (150 individuals in the control group and 85 in the experimental group) as its participants. The data were collected through three separate questionnaires: The Multidimensional Scale of Perceived Social Support Questionnaire, the demographic questionnaire and the researcher-made questionnaire of evaluation of breastfeeding. The T-test, Mann-Whitney, chi-square and logistic regression tests were used for analysis by SPSS 16.<br> <strong><em>Results</em></strong><strong>:</strong> The results revealed that compared to mothers in the experimental group, unwanted pregnancies (p=0.001) and caesarian section deliveries (p=0.007) were significantly more observed in the control group mothers. Those characterized by termination of breastfeeding received (about 22 times) weaker social support compared to the breastfeeding mothers (p<0.001, OR~22). Furthermore, the first breastfeeding upon birth was less (about 0.211 times) observed among the experimental group mothers than the group of mothers characterized by breastfeeding (p=0.006, OR~0.211).<br> <strong><em>Conclusion:</em></strong> Husband encouragement and support and high social support are highly effective in successful breastfeeding and in this line, all-out support for mother, including support by family and society, seem very necessary.<br> &nbsp; social support, breastfeeding, termination of breastfeeding 1 11 http://nmcjournal.zums.ac.ir/browse.php?a_code=A-10-707-1&slc_lang=en&sid=1 Marzieh Faghani Aghoozi mahda.f255@gmail.com 10031947532846007484 10031947532846007484 Yes MSc in Midwifery, Department of Midwifery, School of Nursing and Midwifery, Shahroud University of Medical Sciences, Shahroud, Iran Mohaddeseh Karimi Khoshal mohadese-karimi@yahoo.com 10031947532846007485 10031947532846007485 No M.Sc in Midwifery, Reproductive Health Research Center, Department of Obstetrics & Gynecology, Alzahra Hospital, School of Medicine, Guilan University of Medical Sciences, Rasht, Iran Sanaz Fayazi sanazfaiiazi@yahoo.com 10031947532846007486 10031947532846007486 No MSc, Department of Midwifery, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Shahnaz Tork Zahrani Shahnaz Tork Zahrani@gmail.com 10031947532846007487 10031947532846007487 No Ph.D, School of Nursing and Midwifery, Shahid Beheshti University of Medical Sciences, Tehran, IR Iran Malihe Amerian m.amerian43@yahoo.com 10031947532846007488 10031947532846007488 No MSc in Midwifery, Department of Midwifery, School of Nursing and Midwifery, Shahroud University of Medical Sciences, Shahroud, Iran
