BACKGROUND The World Health Organization recommends exclusive breastfeeding for six months, defined as no other solids or liquids besides breast milk and essential vitamins or medicines. Data about exclusive breastfeeding are limited in Georgia, and the information that exist are provided by national surveys, that present inconsistent numbers. Georgia has recently established a national birth registry, which includes information about early postpartum breastfeeding. The objective of this study was to identify factors associated with exclusive breastfeeding of term newborns at hospital discharge in Georgia, using national registry data. METHODS All live, singleton, term births registered in the Georgian Birth Registry in November and December 2017 were included, with a final study sample of 7134 newborns. Newborns exclusively breastfed at hospital discharge were compared with those who were not, and potential factors were assessed with logistic regression analysis. Hospital discharge normally occurred between 2 and 5 days postpartum. RESULTS The study identified several factors associated with nonexclusive breastfeeding of term newborns at hospital discharge in Georgia: maternal higher education compared to secondary education or less (Adjusted Odds Ratio [AOR] 0.75; 95% CI 0.59, 0.97), caesarean delivery compared to vaginal or assisted vaginal delivery (AOR 0.47; 95% CI 0.37, 0.60), birthweight < 2500 g compared to 3000-3499 g (AOR 0.51; 95% CI 0.27, 0.97), and admission to neonatal intensive care unit after delivery (AOR 0.02; 95% CI 0.02, 0.03). None of the following factors were associated with exclusive breastfeeding at discharge: mother's age, marital status, Body Mass Index (BMI), parity, in vitro fertilization, maternal intrapartum complications and the sex of the newborn. CONCLUSIONS To the authors' knowledge, this is the first time determinants of exclusive breastfeeding at hospital discharge have been studied in Georgia. Several factors associated with nonexclusive breastfeeding at discharge were identified, most noteworthy were caesarean delivery and admission to neonatal intensive care unit. These findings are of importance to the Georgian health authorities and maternal/child non-governmental organizations.

与出院时纯母乳喂养有关的因素：一项使用佐治亚州出生登记处的数据进行的研究。

背景技术世界卫生组织建议纯母乳喂养六个月，即除母乳和必需的维生素或药物外，不要再有其他固体或液体。格鲁吉亚关于纯母乳喂养的数据有限，现有信息由国家调查提供，但数字不一致。佐治亚州最近建立了全国出生登记处，其中包括有关产后早期母乳喂养的信息。这项研究的目的是使用国家注册数据确定与乔治亚州出院时足月新生儿的纯母乳喂养有关的因素。方法纳入了2017年11月和2017年12月在乔治亚州出生登记处登记的所有单胎，足月出生的婴儿，最终研究样本为7134名新生儿。将仅在出院时进行母乳喂养的新生儿与未出院的新生儿进行比较，并通过逻辑回归分析评估潜在因素。出院通常发生在产后2至5天之间。结果研究确定了与乔治亚州出院的足月新生儿非排他性母乳喂养有关的几个因素：母体受教育程度高于中等教育水平或更低（经调整的赔率[AOR] 0.75； 95％CI 0.59，0.97），剖宫产与阴道分娩相比或辅助阴道分娩（AOR 0.47; 95％CI 0.37，0.60），出生体重<2500 g，而3000-3499 g（AOR 0.51; 95％CI 0.27，0.97），分娩后进入新生儿重症监护室（AOR 0.02 ； 95％CI 0.02，0.03）。以下因素均与出院时纯母乳喂养无关：母亲的年龄，婚姻状况，体重指数（BMI），胎次，体外受精，产妇产后并发症以及新生儿的性别。结论据作者所知，这是佐治亚州首次研究出院时纯母乳喂养的决定因素。确定了出院时非排他性母乳喂养的几个因素，最值得注意的是剖腹产和新生儿重症监护病房的入院。这些发现对格鲁吉亚卫生当局和母婴非政府组织都很重要。这是佐治亚州首次研究出院时纯母乳喂养的决定因素。确定了与出院时非排他性母乳喂养相关的几个因素，其中最值得注意的是剖腹产和新生儿重症监护病房的入院。这些发现对格鲁吉亚卫生当局和母婴非政府组织都很重要。这是佐治亚州首次研究出院时纯母乳喂养的决定因素。确定了与出院时非排他性母乳喂养相关的几个因素，其中最值得注意的是剖腹产和新生儿重症监护病房的入院。这些发现对格鲁吉亚卫生当局和母婴非政府组织都很重要。
