The Adequacy of Prenatal Care Utilization Index: its US distribution and association with low birthweight.

The proposed Adequacy of Prenatal Care Utilization Index is applied to data from the 1980 National Natality Survey to assess the adequacy of prenatal care utilization and its association with low birthweight in the United States. The index suggests that only 61.1% of women received adequate prenatal care, including 17.7% with more intensive care; 16.7% received inadequate care. More White women (63.4%) than Black women (51.9%) received adequate prenatal care. Low-birthweight rates were elevated among women with inadequate prenatal care and among those who received more intensive prenatal care.

Assessing the Role and Effectiveness of Prenatal Care: History, Challenges, and Directions for Future Research

Despite the widespread use of prenatal care, the evidence for its effectiveness remains equivocal and its primary purpose and effects continue to be a subject of debate. To provide some perspective on why the effectiveness and organization of prenatal care continue to be debated, the authors (a) briefly review the history of the development of prenatal care in the US; (b) attempt to conceptually define prenatal care in terms of its utilization, content, and quality; and, (c) highlight some of the research controversies and challenges facing investigators and advocates who seek to establish the value of prenatal care. In addition, the authors recommend directions for future research to address persistent questions regarding the function, structure, and significance of prenatal care in improving US perinatal outcomes.

Racial and socioeconomic disparities in childhood mortality in Boston.

We examined racial and income-related patterns of mortality from birth through adolescence in Boston, where residents have high access to tertiary medical care. Childhood mortality was significantly higher among black children (odds ratio, 1.24; P less than 0.05) and low-income children (odds ratio, 1.47; P less than 0.001). Socioeconomic effects varied for different age groups and causes of death. The largest relative disparity occurred in the neonatal and postneonatal periods, and the smallest in adolescence. Of the total racial differential in neonatal mortality (6.88 deaths per 1000 live births), 51.2 per cent occurred in premature infants, 13.4 per cent in term infants who were small for their gestational age, and 25.9 per cent in neonates who were both premature and small for their age. Black neonatal mortality was elevated at all income levels. Beyond the neonatal period, mortality from respiratory disease, fire, and homicide had strong inverse relationships with income, and mortality from injuries to the occupants of motor vehicles was directly related to income. These data suggest that despite access to tertiary medical services, substantial social differentiation in mortality may exist throughout childhood. Equity in childhood survival will probably require policies that emphasize preventive goals.

Maternal outcomes associated with planned primary cesarean births compared with planned vaginal births.

OBJECTIVE: To compare the outcomes and costs associated with primary cesarean births with no labor (planned cesareans) to vaginal and cesarean births with labor (planned vaginal). METHODS: Analysis was based on a Massachusetts data system linking 470,857 birth certificates, fetal death records, and birth-related hospital discharge records from 1998 and 2003. We examined a subset of 244,088 mothers with no prior cesarean and no documented prenatal risk. We then divided mothers into two groups: those with no labor and a primary cesarean (planned primary cesarean deliveries—3,334 women) and those with labor and either a vaginal birth or a cesarean delivery (planned vaginal—240,754 women). We compared maternal rehospitalization rates and analyzed costs and length of stay. RESULTS: Rehospitalizations in the first 30 days after giving birth were more likely in planned cesarean (19.2 in 1,000) when compared with planned vaginal births (7.5 in 1,000). After controlling for age, parity, and race or ethnicity, mothers with a planned primary cesarean were 2.3 (95% confidence interval [CI] 1.74–2.9) times more likely to require a rehospitalization in the first 30 days postpartum. The leading causes of rehospitalization after a planned cesarean were wound complications (6.6 in 1,000) (P<.001) and infection (3.3 in 1,000). The average initial hospital cost of a planned primary cesarean of

Preconception Care Between Pregnancies: The Content of Internatal Care

Objective The objective of this study was to compare international trends in pre-eclampsia rates and in overall pregnancy hypertension rates (including gestational hypertension, pre-eclampsia and eclampsia). Design Population data (from birth and/or hospital records) on all women giving birth were available from Australia (two states), Canada (Alberta), Denmark, Norway, Scotland, Sweden and the USA (Massachusetts) for a minimum of 6 years from 1997 to 2007. All countries used the 10th revision of the International Classification of Diseases, except Massachusetts which used the 9th revision. There were no major changes to the diagnostic criteria or methods of data collection in any country during the study period. Population characteristics as well as rates of pregnancy hypertension and pre-eclampsia were compared. Results Absolute rates varied across the populations as follows: pregnancy hypertension (3.6% to 9.1%), pre-eclampsia (1.4% to 4.0%) and early-onset pre-eclampsia (0.3% to 0.7%). Pregnancy hypertension and/or pre-eclampsia rates declined over time in most populations. This was unexpected given that factors associated with pregnancy hypertension such as pre-pregnancy obesity and maternal age are generally increasing. However, there was also a downward shift in gestational age with fewer pregnancies reaching 40 weeks. Conclusion The rate of pregnancy hypertension and pre-eclampsia decreased in northern Europe and Australia from 1997 to 2007, but increased in Massachusetts. The use of a different International Classification of Diseases coding version in Massachusetts may contribute to the difference in trend. Elective delivery prior to the due date is the most likely explanation for the decrease observed in Europe and Australia. Also, the use of interventions that reduce the risk of pregnancy hypertension and/or progression to pre-eclampsia (low-dose aspirin, calcium supplementation and early delivery for mild hypertension) may have contributed to the decline.

The clinical content of preconception care: preconception care for men.

OBJECTIVES To examine the prevalence, persistence, and correlates of depressive symptoms in mothers of toddlers in a nationally representative sample. METHOD The self-report components of two linked databases were used for this study, the 1988 National Maternal and Infant Health Survey and the 1991 Longitudinal Followup. Depressive symptoms of 7,537 mothers were measured by the Center for Epidemiologic Studies-Depression Scale (CES-D) at both time points. Weighted bivariate and multivariate analyses were used to assess the stability of maternal depressive symptoms across two time points and maternal and child predictors of elevated depressive symptoms. RESULTS Twenty-four percent of mothers at time 1 (mean child age 17 months) and 17% at time 2 (mean child age 35 months) had elevated depressive symptoms (CES-D score > or =16). Thirty-six percent of those with elevated scores at time 1 also had elevated scores at time 2. Not having breast-fed, a mistimed or unwanted pregnancy, and poor child health status were related to elevated depressive symptoms but not persistence. CONCLUSIONS Elevated depressive symptoms are common in mothers of toddlers. Given the potential magnitude of need, a systematic clinical and public health approach may be required.
