Feto-infant health and survival: does paternal involvement matter?

Lack of paternal involvement during pregnancy and infancy may account for a significant burden of the adverse pregnancy outcomes among black women and could therefore, represent an important avenue providing the opportunity to improve feto-infant health and survival. This study aimed to review the literature on paternal involvement during the perinatal period and its influence on feto-infant health and survival. Literature for this review was identified by searching the PubMed database from the National Center for Biotechnology Information at the US National Library of Medicine as well as the ISI Web of Knowledge Databases, OVID, and CINAHL. A total of seven papers were identified and included in this review. There is paucity of data in this domain. Overall findings suggest that paternal involvement during pregnancy may have important implications for maternal prenatal health behaviors and feto-infant health. Although results are limited, results suggest that paternal involvement has a positive influence on prenatal care usage, abstinence from alcohol and smoking, and a reduction in low birth weight and small for gestational age infants. None of the papers examined the relationship between stillbirth and paternal involvement. Additional studies with enhanced measures of paternal involvement are needed to better assess the role of fathers in enhancing prenatal health behaviors and pregnancy outcomes. Efforts should be made to include fathers in future studies and reduce reliance on maternal report and to investigate paternal roles across different racial groups so that appropriate interventions can be developed.

Racial disparities in mortality among infants with Dandy-Walker syndrome.

BACKGROUND: Congenital malformations are the major cause of infant mortality in the United States, but their contribution to overall racial disparity--a major public health concern--is poorly understood. We sought to estimate the contribution of a congenitally acquired central nervous system lesion, Dandy-Walker Syndrome (DWS), to black-white disparity in infant mortality. METHODS: Data were obtained from the New York State Congenital Malformations Registry, an ongoing population-based validated surveillance system. We compared black to white infants with respect to infant, neonatal, and postneonatal mortality using Cox proportional hazards regression models. RESULTS: A total of 196 live-born neonates were diagnosed with DWS in the state from 1992 to 2005 inclusive. Of these, 53 were non-Hispanic black and 76 were non-Hispanic white. Neonatal mortality was similar for non-Hispanic blacks and non-Hispanic whites (adjusted hazards ratio [AHR], 1.42; 95% CI, 0.52-3.82), but non-Hispanic blacks had an 8-fold increased risk for postneonatal mortality (AHR, 8.26; 95% CI, 2.08-32.72). Adjustment for fetal growth and other maternal and infant characteristics resulted in a 10-fold increased risk of mortality for non-Hispanic black infants as compared to non-Hispanic whites. By contrast, adjustment for preterm birth attenuated the risk, but non-Hispanic black infants were still more than 6 times as likely to die during the postneonatal period than non-Hispanic whites (AHR, 6.36, 95% CI, 1.52-26.60). CONCLUSION: DWS has one of the largest black-white disparities in postneonatal survival. This underscores the importance of evaluating racial disparities in infant mortality by specific conditions in order to formulate targeted interventions to reduce disparities.

Dandy-Walker syndrome, associated anomalies and survival through infancy: a population-based study.

OBJECTIVES: To assess infant mortality patterns associated with Dandy-Walker syndrome (DWS) and the impact of concomitant anomalies. METHODS: Data for this study were obtained from the New York State Congenital Malformations Registry, an ongoing population-based validated surveillance system. RESULTS: The 196 cases of DWS had a high infant mortality rate (250/1,000), and the elevated risk correlated positively with additional anomalies in a dose-effect pattern (p for trend <0.01). Infants with DWS and two or more affected organ systems were about 6 times as likely to die postneonatally than their counterparts with isolated DWS [adjusted hazards ratio (AHR) = 6.01; 95% CI = 1.52-24.21]. CONCLUSION: This study confirms the widely held notion that DWS is a heterogeneous rather than a homogeneous entity as shown by the dissimilar infant survival patterns found.

Reproductive characteristics of Southeast Asian immigrants before and after migration.

We describe the reproductive health and practices of Hmong immigrants before and after migration to the United States. Data were gathered as part of an ongoing study on the impact of perinatal exposure to environmental chemicals on children's health in Hmong residents of Green Bay, Wisconsin between August 1999 and May 2002. Of the 742 pregnancies reported by 141 reproductive-aged couples, 669 were live births. The Hmong have an average of 5.2 children (range 0-14) and the sex ratio differed by country of birth. Prenatal care began in the first trimester for 60% of US-born infants, up from 12% prior to immigration. Breastfeeding decreased from 94% and 88% in Laos and Thailand to only 11% for Hmong born in the US. Contraceptive use was reported by 25.5% of women; few reported smoking and alcohol consumption. The results suggest that Hmong immigrants may benefit from public health support targeting prenatal care and breastfeeding practices.
