Racial, ethnic, and socioeconomic disparities in the prevalence of cerebral palsy.

OBJECTIVE: Racial and ethnic disparities in cerebral palsy have been documented, but the underlying mechanism is poorly understood. We determined whether low birth weight accounts for ethnic disparities in the prevalence of cerebral palsy and whether socioeconomic factors impact cerebral palsy within racial and ethnic groups. METHODS: In a retrospective cohort of 6.2 million births in California between 1991 and 2001, we compared maternal and infant characteristics among 8397 infants with cerebral palsy who qualified for services from the California Department of Health Services and unaffected infants. RESULTS: Overall, black infants were 29% more likely to have cerebral palsy than white infants (relative risk: 1.29 [95% confidence interval: 1.19-1.39]). However, black infants who were very low or moderately low birth weight were 21% to 29% less likely to have cerebral palsy than white infants of comparable birth weight. After we adjusted for birth weight, there was no difference in the risk of cerebral palsy between black and white infants. In multivariate analyses, women of all ethnicities who did not receive any prenatal care were twice as likely to have infants with cerebral palsy relative to women with an early onset of prenatal care. Maternal education was associated with cerebral palsy in a dose-response fashion among white and Hispanic women. Hispanic adolescent mothers (aged <18 years) had increased risk of having a child with cerebral palsy. CONCLUSIONS: The increased risk of cerebral palsy among black infants is primarily related to their higher risk of low birth weight. Understanding how educational attainment and use of prenatal care impact the risk of cerebral palsy may inform new prevention strategies.

Maternal and neonatal outcomes after attempted suicide.

OBJECTIVE: The purpose of this study was to describe identifiers and estimate maternal and neonatal outcomes in women who attempt suicide during pregnancy. METHODS: A linked Vital Statistics-Patient Discharge database of the State of California was used to identify cases of intentional injury during pregnancy. A retrospective analysis of maternal and neonatal outcomes in pregnant women who were admitted for attempted suicide is presented. RESULTS: There were 4,833,286 deliveries in California from 1991 to 1999. Of those deliveries, 2,132 were complicated by attempted suicide during pregnancy (0.4 per 1,000 pregnancies). The control population was composed of patients who did not attempt suicide. The group of women that attempted suicide during pregnancy had increases in premature labor, cesarean delivery, and need for blood transfusion. Analysis of neonatal outcomes revealed increases in respiratory distress syndrome and low birth weight infants. A subanalysis, including women who delivered at the hospitalization for attempted suicide, demonstrated increased premature delivery, respiratory distress syndrome, and neonatal and infant death. CONCLUSION: Attempted suicide is associated with significantly higher rates of maternal and perinatal morbidity, and in some cases, perinatal mortality. The best identifier for women at risk for attempting suicide is substance abuse. Care provider identification and prevention are of key importance in preventing these outcomes.
