[Brazilian women and physicians' viewpoints on their preferred route of delivery].

OBJECTIVE: To describe women's preferred route of delivery and physicians' viewpoint on that. METHODS: A total of 656 women who gave birth in the National Health System hospitals of the state of São Paulo and Pernambuco and were enrolled in the Latin American Cesarean Section Study (ELAC) were interviewed. Of them, 230 women were selected from three intervention hospitals where patients routinely sought a second opinion when faced with the decision of undergoing a cesarean section, and 426 women were selected from control hospitals. Also, 72 physicians in the intervention hospitals and 70 in the control hospitals filled out a self-administered structured questionnaire. Data analysis was carried out using Mantel-Haenszel's chi-square test, Yates' test and Fischer's exact test. RESULTS: The majority of women reported preferring vaginal delivery than a cesarean section in both groups of hospitals. This preference was significantly higher among women who had had both vaginal delivery and cesarean section (nearly 90% in both groups of hospitals) compared to those who had cesarean sections only (72.8% in intervention hospitals and 77.8% in control hospitals). According to 45% physicians from intervention hospitals and 55% from control hospitals, most women who underwent cesarean sections are satisfied with that; 81% and 85% physicians from intervention and control hospitals, respectively, believed women prefer a cesarean sections out of fear of vaginal deliveries. CONCLUSIONS: The belief that the main reason for increasing cesarean section rates is fulfilling women's desire by their doctors seems to have no support. Better communication between physicians and pregnant women could possibly contribute to improve the current situation.

Fertility and reproductive history of sterilized and non-sterilized women in Campinas, São Paulo, Brazil.

This article compares sterilized and non-sterilized women in relation to socio-demographic characteristics, reproductive history, and cohabitation status. Women from 30 to 49 years of age and residing in Campinas, São Paulo State, Brazil, were interviewed with a pre-tested and structured questionnaire: 236 women sterilized at least five years before the interview and 236 non-sterilized women. The sterilized women were significantly more likely to be married or cohabiting, to be younger when they began cohabiting, and to have been in the union longer than the non-sterilized women. They also began childbearing at an earlier age and had a history of more pregnancies and more live births than non-sterilized women. Factors associated with a history of 3 or more live births at the time of the interview were surgical sterilization, younger age at first childbirth, older age at the interview, recognition of fewer contraceptive methods, and lower per capita income. The article concludes that sterilization generally appears to be the consequence of higher fertility in a group of women who initiate childbearing early in life, although its role in preventing these women from having even larger families may also have a demographic impact.

[Knowledge adequacy on contraceptives among women in Campinas, Brazil].

OBJECTIVE: An analysis of secondary data was carried out to evaluate the knowledge adequacy on contraceptives and its association with socioeconomic and demographic characteristics. METHODS: The sample consisted of 472 women from the city of Campinas, state of São Paulo, Brazil. Chi-square test was used to evaluate differences among variables and logistic regression was performed to identify independent variables associated with knowledge adequacy (evaluated through a score). RESULTS: Of the total, 47.6% women reached a score higher than six, which was classified as an adequate knowledge on contraceptives. Higher schooling and better socioeconomic status were associated to higher scores of knowledge. CONCLUSIONS: The results show that it is necessary to improve women's education in general, and on contraceptive methods specifically. In addition, professionals working in public health services should be capacitated to provide contraceptives as well as adequate information on contraceptive methods.

[Estimates from a complex survey].

OBJECTIVE: To evaluate the impact of sampling design and the effect of weighting on data from the 1996 Brazilian National Survey on Demography and Health. METHODS: Secondary data analysis was performed using a sample of 1,355 interviewed women of the state of São Paulo. The sampling design of the National Survey of Household Sampling (PNAD) was used as a reference, and the municipality as primary sampling unit. The ratio estimator and Taylor's approximation for variance were calculated using the primary sampling units and several modalities of weighting. The indicators used to evaluate precision and validity were confidence intervals, design effects (Deff) and biases. RESULTS: For the four procedures, the differences between upper and lower point estimates for prevalence were not greater than 10%. The differences on ranges of confidence intervals were less than 20%. Use of condom and hormone injection were the variables that showed design effects greater than 1.5 and biases greater than 0.20. CONCLUSIONS: According to the results, it could be said that the cluster sampling had an impact on the precision of the estimates for two out of six variables. The impact of weighting was not significant.

[Male participation in contraceptive methods use].

This study aimed to evaluate male participation in the use of contraceptive methods and to identify relevant variables. A secondary data analysis was conducted, and the sample size was estimated at 175 men using contraceptives methods that require male participation. The study used the qui-square test to evaluate differences between groups, as well as multiple logistic regression analysis. Some 38% of interviewees used some birth control method that required male participation. Higher level of schooling was associated with the use of some form of contraception requiring male participation, i.e., condom use or vasectomy. Considering the sample's characteristics, the study concluded that it is possible for important changes to take place in Brazilian society with regard to the male perspective on contraception. For these changes to be possible it is necessary to invest in education for both men and women, shown to be an important factor for a balance in gender relations.
