Breastfeeding within the first hour of life is a potential mechanism for health promotion. The purpose of this study was to evaluate the prevalence of breastfeeding initiation within the first hour of life in Feira de Santana, Bahia, Brazil, between 2004 and 2005, and investigate the influence of maternal, child and prenatal factors on this practice.
This is a cross-sectional study extracted from the results of a contemporary cohort conducted in 10 maternity hospitals in the city of Feira de Santana, Bahia, Brazil. A group of 1,309 mother-child pairs was included in the study. Information about mother's and baby's characteristics, pregnancy, birth, and time of breastfeeding initiation was collected in the first 72 hours after delivery, through interview with mothers and hospital records. The data gathered were stored and analyzed using the SPSS 16.0 and R 8.0. The chi-square test and binary logistic regression analysis were used to examine the relationship between breastfeeding within the first hour and different variables.
47.1% of the mothers initiated breastfeeding within the first hour after birth. Early initiation of breastfeeding was associated with birth at full term pregnancy (adjusted Prevalence Ratio 1.43; 95% confidence interval 1.10 to 2.00), mothers who received prenatal guidance regarding the advantages of breastfeeding (aPR1.23; 95% CI 1.11 to 1.41) and vaginal delivery (aPR 2.78; 95% CI 2.38 to 3.23).
In order to improve the rates of breastfeeding within the first hour of life, health care professionals must promote the factors favoring this practice such as prenatal guidance regarding the advantages of breastfeeding, vaginal delivery and full term birth, and stimulate this practice in vulnerable situations such as mothers with cesarean section and preterm birth.
生命最初的一小时内进行母乳喂养是促进健康的一种潜在机制。本研究的目的是评估 2004 年至 2005 年期间巴西巴伊亚州费拉迪圣安娜（Feira de Santana）生命最初的一小时内开始母乳喂养的流行率，并调查产妇、儿童和产前因素对这一实践的影响。
这是一项从巴西费拉迪圣安娜市 10 家妇产医院进行的当代队列研究结果中提取的横断面研究。该研究纳入了 1309 对母婴对。通过对母亲和婴儿的特征、妊娠、分娩和开始母乳喂养的时间进行访谈，在分娩后 72 小时内收集了有关母亲和婴儿的信息，并记录在案。使用 SPSS 16.0 和 R 8.0 存储和分析收集的数据。使用卡方检验和二项逻辑回归分析来检验生命最初的一小时内母乳喂养与不同变量之间的关系。
47.1%的母亲在分娩后最初的一小时内开始母乳喂养。早期开始母乳喂养与足月妊娠（调整后的流行率比 1.43；95%置信区间 1.10 至 2.00）、接受母乳喂养优势产前指导的母亲（调整后的优势比 1.23；95%置信区间 1.11 至 1.41）和阴道分娩（调整后的优势比 2.78；95%置信区间 2.38 至 3.23）相关。
为了提高生命最初的一小时内母乳喂养的比率，医护人员必须促进有利于这种实践的因素，如关于母乳喂养优势的产前指导、阴道分娩和足月分娩，并在剖宫产和早产等脆弱情况下刺激这种实践。
