To analyze the time trend of the rates of cesarean and vaginal delivery according to the source of financing.
This was an ecological study of the time series analysis of cesarean and vaginal delivery rates according to the financing source, carried out in Maringá, Paraná State, Brazil, from 2002 to 2012. Information available at the System of Information on Live Births and at the System of Hospital Information of the Brazilian Unified Health System (SUS) was used for data collection. Moving averages were calculated for all mode of delivery rates in order to smooth random fluctuations in the series, dispersion diagrams were designed between the coefficients and years of the study, and polynomial regression models were estimated from the functional relation observed, with the level of significance set at p<0.05.
Throughout the 11 years of the study there were 48,210 births, 77.1% by cesarean delivery and only 22.9% by vaginal delivery. A total of 22,366 procedures were financed by SUS, 54.6% of them being cesareans. Trend analysis was significant for all the regression models, demonstrating an ascending trend for cesarean delivery and a descending trend for vaginal delivery for both types of financing. The non-SUS cesarean rates always exceeded 90.0% and were more frequent than the SUS cesarean rates, even with a 36.0% increase of the latter during the study period.
Based on trend analysis, cesarean deliveries will continue to increase in both health financing sources unless new actions and strategies of reduction are implemented, involving the sociocultural, demographic and obstetric characteristics of women, the training and activity of professionals in the area of obstetrics and an adequate structure of health services for providing vaginal delivery.

To compare the concentration of serum alpha-tocopherol during the postpartum period in women admitted to public and private hospitals in Natal (RN), Brazil.
The study included 209 women in the postpartum period, 96 of them from private hospitals and 113 from public hospitals, studied between 24 and 48 hours postpartum. Inclusion criteria were: mothers aged 12 years or more, without diseases associated with pregnancy, who had given birth to a singleton with no malformations. Clinically decompensated women with multiple fetuses were excluded. A 5 mL blood sample was obtained from each participant under fasting conditions, before the first meal of the day. The concentration of alpha-tocopherol in serum (µg/dL) was determined by high performance liquid chromatography (HPLC). The statistical difference between means was tested by the Student's t-test.
The mean concentration of alpha-tocopherol was 1.115.7 µg/dL in puerperae from the public network and 1.355.7±397.6 µg/dL in puerperae from the privte network , with a significant difference between groups (p=0.000687). Vitamin E concentration was determined individually and an alpha-tocopherol level <11.6 µmol/L or <499.6 µg/dL was considered to indicate deficiency. Vitamin E deficiency was detected in 5.3% of puerperae from the public network (n=6), whereas no deficiency was detected among women from the private network. However, low concentrations of alpha-tocopherol (11.6 to 16.2 µmol/L or 499.6 to 697.7 µg/dL) was detected in both groups, i.e., in 9.7% of the women from the public network (n=11) and in 4.2% for the women from the private network (n=4).
These results highlight that women assisted in the public sector were more vulnerable to developing low concentrations of alpha-tocopherol than women assisted in the private sector.
