Objective: To learn whether weekend risk of neonatal mortality is related to selected sociodemographic factors.
Design: A retrospective cohort design. Logistic regression was used to obtain odds ratios, and analysis of variance and chi-square to identify differences in values and incidence of key variables.
Samples: The data were derived from matched Texas birth and infant death certificates from 1999 through 2001.
Main outcome measures: A subset of deaths up to 28 days of life attributable to conditions originating in the perinatal period. These deaths were called neonatal mortality-p.
Results: Women who were White, married, had Medicaid assistance, and had private prenatal care were less likely to deliver on weekends. Odds of neonatal mortality-p increased 36.5% when a birth took place on the weekend. The weekend crude odds of neonatal mortality-p increased for all racial/ethnic groups, but the differences were not statistically significant.
Conclusions: The likelihood of delivering on the weekend increases with certain sociodemographic factors. This fact is important because the risk of neonatal mortality is higher among weekend births.
