Objective To identify the variables associated with breastfeeding duration. Data Sources The health science reference databases of CINAHL, PubMed, and the Cochrane Database of Systematic Reviews. Study Selection Meta-analyses, Cochrane reviews, literature reviews, and quantitative and qualitative studies published in English from 1998 through 2008. Data Extraction Data included all variables, both positive and negative, that were found to influence the outcome of breastfeeding duration. Data Synthesis Demographic factors that influence breastfeeding duration are race, age, marital status, education, socioeconomics, and Special Supplemental Nutrition Program for Women, Infants, and Children status. Biological variables consisted of insufficient milk supply, infant health problems, maternal obesity, and the physical challenges of breastfeeding, maternal smoking, parity, and method of delivery. Social variables included paid work, family support, and professional support. Maternal intention, interest, and confidence in breastfeeding were psychological variables. Conclusion Human lactation is a complex phenomena and the duration of breastfeeding is influenced by many demographic, physical, social, and psychological variables.

Variables Associated With Breastfeeding Duration

OBJECTIVE. This study compared the effects of immediate (ICC) and delayed (DCC) cord clamping on very low birth weight (VLBW) infants on 2 primary variables: bronchopulmonary dysplasia (BPD) and suspected necrotizing enterocolitis (SNEC). Other outcome variables were late-onset sepsis (LOS) and intraventricular hemorrhage (IVH). STUDY DESIGN. This was a randomized, controlled unmasked trial in which women in labor with singleton fetuses RESULTS. Seventy-two mother/infant pairs were randomized. Infants in the ICC and DCC groups weighed 1151 and 1175 g, and mean gestational ages were 28.2 and 28.3 weeks, respectively. Analyses revealed no difference in maternal and infant demographic, clinical, and safety variables. There were no differences in the incidence of our primary outcomes (BPD and suspected NEC). However, significant differences were found between the ICC and DCC groups in the rates of IVH and LOS. Two of the 23 male infants in the DCC group had IVH versus 8 of the 19 in the ICC group. No cases of sepsis occurred in the 23 boys in the DCC group, whereas 6 of the 19 boys in the ICC group had confirmed sepsis. There was a trend toward higher initial hematocrit in the infants in the DCC group. CONCLUSIONS. Delayed cord clamping seems to protect VLBW infants from IVH and LOS, especially for male infants.

Delayed Cord Clamping in Very Preterm Infants Reduces the Incidence of Intraventricular Hemorrhage and Late-Onset Sepsis: A Randomized, Controlled Trial

Placental Transfusion Strategies in Very Preterm Neonates: A Systematic Review and Meta-analysis

BACKGROUND AND OBJECTIVE: Delayed cord clamping (DCC) has been advocated during preterm delivery to improve hemodynamic stability during the early neonatal period. The hemodynamic effects of DCC in premature infants after birth have not been previously examined. Our objective was to compare the hemodynamic differences between premature infants randomized to either DCC or immediate cord clamping (ICC).

METHODS: This prospective study was conducted on a subset of infants who were enrolled in a randomized controlled trial to evaluate the effects of DCC versus ICC. Entry criteria included gestational ages of 24 to 316 weeks. Twins and infants of mothers with substance abuse were excluded. Serial Doppler studies were performed at 6 ± 2, 24 ± 4, 48 ± 6, and 108 ± 12 hours of life. Measurements included superior vena cava blood flow, right ventricle output, middle cerebral artery blood flow velocity (BFV), superior mesenteric artery BFV, left ventricle shortening fraction, and presence of a persistent ductus arteriosus.

RESULTS: Twenty-five infants were enrolled in the DCC group and 26 in the ICC group. Gestational age, birth weight, and male gender were similar. Admission laboratory and clinical events were also similar. DCC resulted in significantly higher superior vena cava blood flow over the study period, as well as greater right ventricle output and right ventricular stroke volumes at 48 hours. No differences were noted in middle cerebral artery BFV, mean superior mesenteric artery BFV, shortening fraction, or the incidence of a persistent ductus arteriosus.

CONCLUSIONS: DCC in premature infants is associated with potentially beneficial hemodynamic changes over the first days of life.
