[Validation of birth certificates based on data from a case-control study].

The information recorded on birth certificates was validated with data from a perinatal mortality case-control study, obtained from home interviews of mothers and hospital records for cases (early neonatal deaths) and controls. Sensitivity, specificity, and concordance were calculated for all variables and their estimated and real prevalence. The completeness of birth certificates was lowest for mother's parity and presence of congenital anomalies (records without information range from 23% to 31% for cases and controls). Birth certificates correctly identified low birth weight and type of delivery for cases and controls. Birth certificates showed high sensitivity and specificity to detect preterm births within cases. The number of preterm births was underestimated at 30.8% of the controls and 2.9% of the cases. Low maternal education was two times greater on birth certificates than in the mother's interview, for cases and controls. Completeness of birth certificates was higher in controls, but data quality was better in cases.

[Accidental home deliveries in southern São Paulo, Brazil].

OBJECTIVE: To identify the frequency, risks of fetal and early neonatal mortality and the determinants of accidental home deliveries. METHODS: A population-based case control study of fetal and early neonatal deaths was carried out in the southern area of São Paulo, Brazil. Data were collected through home interviews and hospital record reviews. The reasons reported by the mothers were obtained from interviews and risk factors for home delivery were obtained comparing home to hospital deliveries. Data were analyzed separately for fetal and early neonatal deaths and survivors. Odds ratios, 95% confidence intervals and Fisher's exact test were used in estimating risk factors and mortality risk. RESULTS: The 0.2% frequency of home deliveries was underestimated in the live births information system. After adjustment, it reached 0.4%, comparable to other urban areas in Europe. All home deliveries identified were accidental and were associated to an increased fetal and early neonatal mortality. Mothers' social conditions and pregnancy characteristics were associated to accidental home deliveries and these factors are different outcomes studied (fetal losses, early neonatal deaths and survivors). In 30%, mothers reported lack of available transportation to the hospital as a reason for home delivery. Failure of health services in identifying labor women and non-availability of emergency care contributed to accidental home deliveries. CONCLUSIONS: Though rare events in urban areas, accidental home deliveries should be of special concern to health services because they seem to be avoidable and imply in increased risk of death.
