Regret following female sterilization at a young age: a systematic review

Women who undergo sterilization may later regret this decision. This systematic review examines whether age at sterilization is associated with poststerilization regret. Using MEDLINE and EMBASE, we identified 19 articles that examined associations between women's age at sterilization and later regret, requests for sterilization reversal and undergoing sterilization reversal or requesting in vitro fertilization (IVF) procedures. Study results showed that the younger women were at the time of sterilization, the more likely they were to report regretting that decision. Women undergoing sterilization at the age 30 years or younger were about twice as likely as those over 30 to express regret. They were also from 3.5 to 18 times as likely to request information about reversing the procedure and about 8 times as likely to actually undergo reversal or an evaluation for IVF. Results of studies that examined risk by continuous age showed a consistent inverse relationship between women's age at sterilization and their likelihood of regretting having had the procedure.

Barriers to obtaining a desired postpartum tubal sterilization

OBJECTIVE

To determine why women do not undergo postpartum sterilization despite expressing desire during antepartum care.

METHODS

In a retrospective chart review, we identified all women between March 2002 and November 2003 who requested postpartum sterilization during antepartum care but did not undergo the procedure. We report the reasons why sterilizations were not performed.

RESULTS

We reviewed 6,589 prenatal care and delivery records identifying 324 women meeting inclusion criteria. One hundred and four women changed their mind. Of women still desiring sterilization at discharge, the most common reasons for not undergoing the procedure were lack of valid Medicaid sterilization consent forms [n=121; 37.3%, 95% confidence interval (CI) 32.0-42.6%]; a medical condition precluding the procedure (n=47; 14.5%, 95% CI 10.7-18.3%); lack of availability of an operating room (n=2; 6.5%, 95% CI 3.8-9.2%).

CONCLUSION

We found that the Medicaid consent process, medical conditions and insufficient operating room space prevented women from having the desired surgery.

Do risk factors for epithelial ovarian cancer have an impact on prognosis? Focus on previous pelvic surgery and reproductive variables

OBJECTIVES

The prognostic impact of risk factors for ovarian cancer development is sparsely explored, but previous sterilisation has been shown to have a negative impact on survival.

METHODS

Ovarian cancer cases were from the Danish MALOVA study. Information on previous pelvic surgery as well as reproductive variables was obtained from a personal interview conducted closely after primary surgery. Cox regression models were used to estimate adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) for ovarian cancer specific death in relation to previous pelvic surgery and reproductive variables including lifetime number of ovulation years.

RESULTS

A total of 295 women with Stage III ovarian carcinomas were identified and followed to death or for a median of 7.3 years (range 5.4-9.5 years). Previously sterilised or hysterectomised women seemed to have a slightly decreased risk of ovarian cancer death (HR = 0.62; 95% CI: 0.36-1.08 and HR = 0.82; 95% CI: 0.55-1.21), although none of these associations reached statistical significance. The prognostic impacts of the individual reproductive variables followed the same pattern as the impact of the variables on ovarian cancer development, although significance was only reached for age at menarche (HR = 0.91 per year; 95% CI: 0.84-0.99). By accumulation of the possible minor effects of the reproductive variables in calculation of the total lifetime number of ovulation years, we found that survival decreased significantly with increasing number of ovulations (HR = 1.53 per 10 years; 95% CI: 1.09-2.14).

CONCLUSION

Increasing lifetime number of ovulations was a negative prognostic factor for ovarian cancer specific survival. Previous sterilisation or hysterectomy seemed to be associated with improved survival.

Características dos candidatos à esterilização cirúrgica e os fatores associados ao tipo de procedimento

Em 1999, a Secretaria Municipal de Ribeirão Preto, São Paulo, Brasil, implantou a oferta de métodos de esterilização cirúrgicos, de acordo com a legislação vigente. Este estudo objetivou caracterizar os candidatos à esterilização cirúrgica e estudar as variáveis associadas ao tipo de procedimento. Foram pesquisados 95 prontuários de candidatos e realizada análise estatística por meio de regressão logística e do teste exato de Fisher, considerando-se o nível de significância de p = 0,05. A maioria dos candidatos são casais estáveis, de baixa escolaridade e baixa renda, satisfeitos com o número de filhos e que já haviam tentado limitar a prole com o uso de anticoncepcionais reversíveis. A média de idade era de 34,2 anos; 45,3% se submeteram à esterilização feminina; 35,8%, à vasectomia, e 18,9% não obtiveram o procedimento. A chance de o homem, com 35 anos ou mais, fazer vasectomia é 6,1 vezes a do homem mais jovem (OR = 6,1; IC95%: 2,4-16,4); submetem-se à vasectomia mais homens casados do que os que coabitam (OR = 4,0; IC95%: 1,5-12,4) e mulheres com quatro filhos ou mais fazem mais laqueadura do que aquelas com menos de quatro filhos (OR = 3,1; IC95%: 1,1-8,5).

Changes in family structure and regret following tubal sterilization

Tubal sterilization is one of the contraceptive methods whose use has increased the most in Brazil, but a growing number of women have expressed regret after the procedure. A case-control study was conducted at the Centro Integrado de Saúde Amaury de Medeiros (CISAM), Recife, Pernambuco, Brazil, in 1997 to investigate the association between changes in family structure and request for or submittal to surgical reversal of tubal sterilization, comparing 304 sterilized women who had requested or submitted to reversal of tubal sterilization and 304 women who were also sterilized but had not requested, had not submitted to, and who did not wish to submit to reversal. The simple and adjusted odds ratios were estimated using logistic regression. The results of the current study showed that death of children, partners without children prior to the current union, and partner change after tubal sterilization were associated with the request for or submittal to reversal of tubal sterilization. More strict criteria are suggested in the indication of tubal sterilization, including an in-depth profile of the woman requesting tubal sterilization and identification of risk factors for future regret.

Contraceptive use--United States and territories, Behavioral Risk Factor Surveillance System, 2002

PROBLEM

Contraceptive use is an important determinant of unintended pregnancy. In the United States, approximately half of all pregnancies are unintended. Population-based information about contraceptive use patterns is limited at the state level. Information about contraceptive use for states can be used to guide the development of state programs and policies to decrease unintended pregnancy and the spread of sexually transmitted infections. Information about contraceptive use for specific subpopulations can be used to further refine state efforts to improve contraceptive use and subsequently decrease the occurrence of unintended pregnancy.

REPORTING PERIOD

Data were collected in 2002 for men and women.

DESCRIPTION OF SYSTEM

The Behavioral Risk Factor Surveillance System (BRFSS) is a random-digit--dialed, telephone survey of the noninstitutionalized U.S. population aged > or =18 years. All 50 states, the District of Columbia, Guam, the Commonwealth of Puerto Rico, and the U.S. Virgin Islands participated in BRFSS in 2002. These data can be used to track state progress towards the national health objectives for 2010 for responsible sexual behavior. The 2002 BRFSS data represent the first time state data on contraceptive use in all 50 states will be presented and examined by selected sociodemographic characteristics. The 2002 BRFSS also, for the first time, provided an opportunity to examine state-level contraceptive use patterns among men.

RESULTS

Variation across states and territories was observed for the majority of contraceptive methods among the different demographics analyzed and among men and women. The percentage of men and women at risk for pregnancy who said they or their partner was using birth control was high overall and ranged from 67% (Guam) to 88% (Idaho). Oral contraceptives (i.e., the pill), vasectomy, tubal ligation, and condoms were the methods most frequently reported by both male and female respondents who said they or their partner was using birth control. Among female respondents using birth control, the pill was the most common method reported. Among men, vasectomy was the most commonly reported method. The prevalence of use for the four most commonly reported methods (pills, vasectomy, tubal ligation, condoms) varied as much as six-fold among states for vasectomy and three- to four-fold for condoms, pills, and tubal ligation.

INTERPRETATION

The findings in this report document substantial differences among states and sociodemographic groups within states in contraceptive method use.

PUBLIC HEALTH ACTION

These data can help states identify populations with an unmet need for birth control, barriers to birth control use, and gaps in the range of birth control methods offered by health-care providers. An analysis of the prevalence of birth control use by state and selected population characteristics can help states target contraceptive programs to best meet the needs of their population.

The impact of franchised family planning clinics in poor urban areas of Pakistan

This study uses a quasi-experimental design to determine the impact of new family planning clinics on knowledge, contraceptive use, and unmet need for family planning among married women in poor urban areas of six secondary cities of Pakistan. Baseline (n = 5,338) and endline (n = 5,502) population surveys were conducted during 1999-2000 and 2001-02 in four study sites and two control sites. Exit interviews with clients identified the sociodemographic and geographic characteristics of clinic users. The results show that the clinics contributed to a 5 percent increase in overall knowledge of family planning methods and an increase in knowledge of female sterilization and the IUD of 15 percent and 7 percent, respectively. Distinct effects were found on contraceptive uptake, including an 8 percent increase in female sterilization and a 7 percent decline in condom use. Unmet need for family planning declined in two sites, whereas impacts on the other sites were variable. Although the new clinics are located within poor urban communities, users of the services were not the urban poor, but rather were select subgroups of the local population.

Failure to obtain desired postpartum sterilization: risk and predictors

OBJECTIVE

The aim of this study was to assess the rate of and risk factors for not obtaining postpartum sterilization among women who expressed a desire for sterilization during antepartum care.

METHODS

In this retrospective study, we identified a cohort of women who expressed desire for postpartum sterilization at our center between March 2002 and November 2003. We compared women who did and those who did not undergo the procedure, based on demographic, antenatal, and intrapartum factors.

RESULTS

Of the 712 women who expressed desire for postpartum sterilization during antepartum care, 327 (46%) did not undergo the procedure. In multivariable analysis, women who were between the ages of 21 and 25 years (adjusted odds ratio [OR] 0.56, 95% confidence interval [CI] 0.35-0.89), were African American (OR 0.68, 95% CI 0.47-1.00), requested sterilization in the second trimester (OR 0.50, 95% CI 0.29-0.86)), and had a vaginal delivery (OR 0.21, 95% CI 0.14-0.32) rather than cesarean delivery were least likely to undergo postpartum sterilization.

CONCLUSION

Despite their initial request, only 54% of women in our sample underwent sterilization. Young age, African-American race, request in the second trimester, and vaginal delivery were significantly associated with not undergoing sterilization. Our data suggest that providers should counsel all women who desire postpartum sterilization about the wide array of contraceptive methods available, with the understanding that approximately half of all women may not undergo the sterilization procedure.

LEVEL OF EVIDENCE

II-2.

Multiple repeat caesarean section: is it safe?

OBJECTIVE

We aimed to evaluate the obstetric outcome of patients without obstetric risks, who had two or more previous caesarean sections (C/S) prior to the current pregnancy, which was managed by caesarean section in our obstetric department.

METHODS

We studied the case notes of 602 women who had a repeat caesarean section in our unit between May 2002-June 2003. We then compared the two groups: (1) those who had two or more previous caesarean sections and (2) those who had only one previous caesarean section.

RESULTS

In the study group, while dense intraperitoneal adhesions were present in 3.6% of the patients, they were not found in control group. This difference was statistically significant (P < 0.05). Uterine wound separation rate was 1.9% in the study group and none of the patients in control group had uterine wound separation, which was statistically significant also (P < 0.05). There was no statistically significant association between Apgar scores and number of previous caesarean sections. Postoperative complication rates did not differ between the two groups (P > 0.05).

CONCLUSION

Patients without any obstetric risks, with two or more previous caesarean sections had significantly more dense adhesions and uterine wound separations in the current caesarean section compared to patients with one previous caesarean section. But, maternal and fetal mortality and morbidity in women who have two or more previous caesarean sections did not differ from the patients with one previous caesarean section.

Provision of female sterilization in Ribeirão Preto, São Paulo, Brazil

Forty percent of Brazilian married women from 15 to 49 years of age have undergone surgical sterilization. The 1988 Brazilian Constitution states that all scientifically proven contraceptive methods should be available to all citizens, but it was only in 1997 that specific family planning legislation was approved. This study examines physicians' perceptions and attitudes towards the current provision of female sterilization and its legal implications, as well as women's experience with obtaining and undergoing sterilization. The study design included: (1) an investigation of the hospitals and health professionals and (2) a survey of women sterilized in combination with cesarean delivery in 1998. The survey showed they had a median of 3 living children, 60.0% had been sterilized between 30 and 39 years of age, and 61.0% had paid for the procedure. Many women reported previous method failure and adverse effects with hormonal contraceptives. Women with less schooling and lower socioeconomic status had more children and had begun childbearing and had been sterilized at younger ages than women with more schooling and higher socioeconomic status. Inequalities related to reproduction were strongly associated with teenage pregnancy and inadequate knowledge about contraceptives.

Adhesion-related readmissions following gynaecological laparoscopy or laparotomy in Scotland: an epidemiological study of 24 046 patients

BACKGROUND

Gynaecological laparotomies are associated with considerable adhesion-related burdens; however, few data are available concerning laparoscopic surgery. This study evaluated the epidemiology of adhesion-related readmissions following open and laparoscopic procedures.

METHODS

Records from 24,046 patients undergoing gynaecological surgery in Scottish National Health Service hospitals during 1996 were assessed retrospectively. Cohorts comprised 15,197 patients undergoing laparoscopic surgery and 8849 patients undergoing laparotomies. Adhesion-related readmission episodes (directly and possibly related) were assessed over 4 years following initial surgery and were expressed as percentages of the number of initial procedures.

RESULTS

Directly adhesion-related readmissions 1 year after initial laparoscopic surgery were: in the high-risk group (adhesiolysis and cyst drainage) 1.3%; medium-risk (therapeutic and diagnostic procedures not categorized as high- or low-risk) 1.5%; and low-risk (Fallopian tube sterilizations) 0.2%. Readmissions for laparotomy following surgery on the Fallopian tubes were 0.9%, ovaries 2.1%, uterus 0.6% and vagina 0%. Readmissions occurred at reduced rates in the second, third and fourth years after surgery. Exclusion of patients who underwent surgery within the previous 5 years resulted in reduced readmission rates following laparotomy and high-risk laparoscopy.

CONCLUSIONS

With the exception of laparoscopic sterilizations, open and laparoscopic gynaecological surgery are associated with comparable risks of adhesion-related readmissions.

Female voluntary surgical contraception via minilaparotomy under local anesthesia

OBJECTIVE

To examine changes in prevalence and acceptance of sterilization methods in a developing country from 1986 to 1990.

METHOD

Data from 5182 voluntary female sterilizations performed at 52 service sites in Nigeria were retrospectively reviewed for sterilization method, anesthesia technique, demographic factors, and patient acceptance.

RESULTS

The annual number of sterilization procedures increased dramatically over this period from 688 in 1986 to 1911 in 1989. Overall, 74.3% of the procedures were performed by minilaparotomy under local anesthesia (ML/LA), 6% by laparoscopy/general anesthesia, and 19.7% by laparatomy/general anesthesia. ML/LA was found to be a very safe method, with a complication rate of 1.4%. 98.6% of ML/LA patients expressed complete satisfaction with the procedure.

CONCLUSION

Female sterilization increased in acceptance in Nigeria over the period 1986-1990 concomitant with the increased use of ML/LA. This approach is safe, cost-effective, and appropriate for the developing world.

Female surgical sterilization at a tertiary care hospital in Karachi

BACKGROUND

Tubal ligation for sterilization is one of the common methods of contraception practiced by women in developing countries like Pakistan. This study was undertaken to study characteristics of couples undergoing surgical sterilization, and to identify ways of improving utililization of contraceptive services.

MATERIAL AND METHODS

Details of 1148 women who underwent tubal ligation at the reproductive health center Jinnah Postgraduate Medical Center Karachi from January to December 2002 were recorded on a special proforma. The woman's age, duration of marriage, number of living children and the couple's educational status were recorded. Contraceptive use and duration, and associated medical conditions were documented. Data was entered in SPSS, frequency tables, means and standard deviations were obtained and comparative evaluation undertaken using non parametric methods, as indicated.

RESULTS

Out of the 4210 initial clients, 1163 (27.62%) underwent surgical sterilization. This included 1148 (98.69%) tubal ligations and 15 (1.31%) vasectomies. Of these, 608 (52.96%) were carried out in the immediate puerperium. The mean age of women was 33.1+/-3.55 years, they had been married for 14.84+/-4.22 years and 44.34% had already had 6 or more children.

CONCLUSION

Tubal ligation performed after careful selection and counseling, by experienced personnel under local anaesthesia is a safe procedure with very few complications. However older women with no history of contraception, who have already had 6 or more children, seem to avail it. Promotion of temporary contraceptives for birth spacing among younger couples is more likely to improve maternal and newborn health in addition to limiting the family size.

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.

The incidence of sterilisation in the UK

OBJECTIVE

To estimate incidence rates for tubal occlusion and vasectomy, and to examine how these vary with age, geographical area and time.

DESIGN

Search of patient files for operation codes in the years 1992-1999 and calculation of person time.

POPULATION AND SETTING

General Practice Research Database.

METHODS

Patient files of women aged 20-54 years and men aged 20-64 years were searched for sterilisation operation codes. Annual incidence rates in five year aged bands were calculated for sterilisation operations for both sexes. Figures were examined according to National Health Service Region and population density category of the general practices. The relationship between year of operation and mean age at operation was also examined.

MAIN OUTCOME MEASURES

Incidence rates by year, age group and geographical area.

RESULTS

The average annual incidence of sterilisation in the eight year period was 4.75 per 1000 person years at risk for women aged 20-54 and 4.48 per 1000 person years at risk for men aged 20-64. For women, there was a statistically significant 30% decrease in incidence of tubal occlusion over the study period. There was no change in vasectomy rates over time. About one-third of all vasectomies in the UK are estimated to be performed outside hospital and community clinic settings. The rates of sterilisation in both sexes were much lower in Greater London than elsewhere in the UK.

CONCLUSIONS

The popularity of tubal occlusion appears to be on the decline. Since 1996, the UK has been one of very few countries in which sterilisation incidence in men is greater than that in women.

Female sterilisation: is it what women really want?

OBJECTIVE

To audit the effectiveness of a female sterilisation counselling clinic.

DESIGN

A prospective, observational study of a female sterilisation counselling clinic over a 6-month period to determine the proportions of attenders keeping their appointment, proceeding to sterilisation, and attending for surgery.

SETTING

A hospital-based, city centre family planning clinic run by permanent, family planning-trained staff.

RESULTS

A total of 226 women had appointments for female sterilisation counselling and most confirmed attendance. Only 153 (68%) women attended; of those 101 (66%) chose to be sterilised, the remainder choosing reversible contraception. Ninety-three (92%) women went ahead with the sterilisation procedure. Thus only 61% of the original attenders were sterilised; this was only 41% of those referred.

CONCLUSIONS

The study suggests that many women referred for sterilisation counselling fail to attend. This finding needs to be further explored. For those women who do attend, accurate information and informed counselling is important. Many women are still unaware of highly effective long-term reversible contraception, and following discussion decide against female sterilisation. Services offering counselling for female sterilisation should also be able to provide easy access to a full range of contraceptive methods.

Voluntary surgical contraception: a study on level of satisfaction

Voluntary surgical contraception (VSC) is said to be one of the most popular, safe, effective and long term methods of birth control not only in Nepal but also in the world One of the very frequently suspected complication or effect of voluntary sterilization (female) is "post tubal sterilization syndrome". The term post tubal sterilization syndrome has been used variously to include abnormal menstrual bleeding, dysmenorrahoea, premenstrual distress, hysterectomy and miscellaneous other conditions like need for recanalisation, feeling of regret and menopausal syndrome. Abnormal vaginal bleeding due to ovarian dysfunction has been a regular and common complaint of the female clients after their TS. This study was carried out in a clinic setting to find out the level of satisfaction among the cases of VS. Level of satisfaction was measured by whether the client regretted the procedure, whether their menstrual pattern was changed after the procedure, performed either by themselves or VSC by the husband and also by finding out how many of them needed hysterectomy and recanalisation procedure. Women who had undergone TS were taken as the cases (group A) and those women whose husband has VSC were taken as control group (group B). The result showed that there is almost no difference in the age group of both case and control at the time of their consultation. At the time of VS almost 60% (56.53%) of cases were <29 years of age and >70% (71.23%) of the women were <29 years of age when their husbands were vasectomised. 26.15% of the women in group A were in the age group of 30-40 whereas this age group comprised of only 15.38% in group B. Average age at menarche was 14 years and average age at marriage 17 years. The menstrual pattern was not found to have changed in both groups excepts for those who had organic condition. Hysterectomy had been performed in only 5 cases at the age of 30, 34, 40, 42 and 43 years in group-A and in two case in group-B. Indications of hysterectomy n these cases were (DUB) and fibroids. Two patients in group-A had to undergo recanalisation but the indication in both the cases were loss of previous children.

Child disability and mothers' tubal sterilization

CONTEXT

The needs of children with disability can be substantial, leading some parents to consider contraceptive sterilization to prevent additional births.

METHODS

Matched records from the 1993 National Health Interview Survey and the 1995 National Survey of Family Growth were used to investigate the relationship between child disability and mothers' sterilization. Data included the birth records of 8,711 children, information on older children in the household, and the mothers' background and reproductive characteristics. Logistic and Cox regression models were used to estimate the effect of the birth of a child with a disability on the risk of mothers' sterilization.

RESULTS

The birth of a child with disability has no effect on the likelihood that a mother will undergo sterilization within the next month; however, women who have an older child with severe disability are more likely than those whose older children are nondisabled to undergo sterilization within a month after the birth of another child (odds ratio, 2.6). Severe disability in a newborn significantly increases the risk of sterilization 1-36 months after birth (risk ratio, 1.7); severe disability among older children also appears to increase the risk of sterilization 1-36 months after birth (1.5), although this result was only marginally significant.

CONCLUSIONS

Women often respond to the birth of children with disabilities by changing their fertility plans, although usually not immediately unless they have older children with severe disability. These findings are consistent with parents'desire to have a nondisabled child and with their need to care for an exceptional child by forgoing additional births.

Frustrated demand for postpartum female sterilization in Brazil

During the last three decades, Brazilians have relied almost exclusively on two contraceptive methods, the pill and female sterilization, with sterilization use increasing over time. Until a new law was passed in 1997, sterilization was virtually illegal and not covered by either public or private health insurance. It was, however, frequently provided in public and private hospitals in conjunction with a cesarean section. The new law regulating sterilization provided for reimbursement for interval sterilizations by public health insurance, but placed restrictions on availability intended to reduce the use of cesareans. These restrictions included the prohibition of postpartum sterilizations. This paper focuses on women's sterilization intentions during pregnancy and their experiences postpartum. In a prospective study of 1612 pregnant women carried out in four Brazilian cities, there was substantial demand for postpartum sterilization in both the private and public sectors among women who wanted no more children. However, public patients were much less likely to be sterilized than private patients. Thus, the new law may not have reduced inequities in access or, paradoxically, the incentive for unnecessary cesarean sections.

Sterilization failure, sterilization reversal, and pregnancy after sterilization reversal in Quebec

OBJECTIVE

1). To determine the likelihood of sterilization reversal and of subsequent sterilization after sterilization reversal among men and women and 2). to examine the likelihood of pregnancy after sterilization (contraceptive failure) and of pregnancy after sterilization reversal.

METHODS

Payment data from the Quebec provincial health insurance system were obtained for each person undergoing vasectomy or female sterilization from January 1, 1980 to December 31, 1999 and linked through a unique identifying number for each person. Using standard techniques of survival analysis, we computed the cumulative probability of experiencing each of six events.

RESULTS

Among women, 0.9% (of 311960) experienced a pregnancy after sterilization, 1.8% (of 321929) obtained a reversal after sterilization, 61% (of 4369) achieved a pregnancy after sterilization reversal and 48% achieved a delivery; 23% (of 4677) obtained a subsequent sterilization after reversal. Among men, 2.4% (of 310827) obtained a reversal after vasectomy and 18% (of 6694) obtained a subsequent vasectomy after reversal. All of these risks were much higher among those in the youngest age groups.

CONCLUSION

Sterilization reversal and pregnancy after sterilization are not rare. Relatively high rates of reversal among the youngest age groups suggest a need for better counseling about alternative contraceptive strategies.

Esterilização feminina, AIDS e cultura médica: os casos de São Paulo e Porto Alegre, Brasil

Este artigo busca identificar os fatores que interferem nas escolhas reprodutivas de gestantes HIV positivo focalizando, em particular, o papel desempenhado pelos serviços de saúde e pela cultura médica nessas escolhas. O desejo e a realização de laqueadura tubária pós-parto constituem os eventos reprodutivos tomados como questões de análise. Os dados apresentados resultam de uma pesquisa desenvolvida em serviços de pré-natal nas cidades de São Paulo e Porto Alegre, que utilizou um desenho que combinou duas estratégias metodológicas: quantitativa, a partir de dados coletados em 427 prontuários clínicos, e qualitativa, por meio da observação etnográfica e realização de sessenta entrevistas em profundidade. A grande maioria de mulheres nas duas cidades manifestou o desejo de realizar a esterilização depois do parto. Entretanto, uma proporção muito maior de mulheres em São Paulo atingiu sua meta comparada a uma pequena proporção em Porto Alegre. A cultura médica local com relação à laqueadura, aliada à organização da prática de assistência ao pré-natal e parto, mostrou-se fator fundamental para compreender as diferenças encontrada nas duas cidades.

Direitos reprodutivos de mulheres e homens face à nova legislação brasileira sobre esterilização voluntária

O objetivo deste trabalho é analisar os impactos e as possíveis mudanças que a implementação da nova legislação sobre planejamento familiar teve nas práticas reprodutivas, especialmente na esterilização voluntária, e observar se os diretos reprodutivos de mulheres e homens têm sido satisfeitos. A abordagem metodológica é baseada em uma pesquisa follow-up, aplicada a uma amostra de 159 indivíduos durante seis meses e em seis diferentes capitais de estado. Além de verificar se os critérios estabelecidos na lei estavam sendo seguidos pelo setor público de saúde, nós analisamos o tempo de espera entre a solicitação pela esterilização e a realização da cirurgia, utilizando análise de sobrevivência. Adicionalmente, foram realizadas entrevistas com profissionais de saúde, as quais são muito elucidativas dos procedimentos adotados na prática da esterilização. Os resultados mostram que, por diferentes motivos, a lei mudou pouco a prática usual da esterilização e ainda não satisfaz os direitos reprodutivos de mulheres e homens no Brasil.

Ruptured uterus at Sagamu, Nigeria

Ruptured uterus, the largest contributor to maternal deaths in our center was reviewed to find ways of reducing it and improve the outcome. Sixty cases treated at Ogun State University Teaching Hospital, Sagamu between January 1988 and December 1997 were scrutinised. During the 10 year period, total deliveries were 5,214 giving an incidence of 11.5 per 1,000. 76.7% of cases occurred in patients aged 30 years and more; and 58.6% in para 4 and more. 88.3% were unbooked. The ruptures were spontaneous in 76.7% and lower uterine segment was the most common (80%). Uterine repair with sterilisation was carried out in 46.7%, sub total hysterectomy in 26.7% and repair only in 11.7%. Most of the aetiological factors were preventable by good antenatal care and the outcome improved by early referral and efficient blood transfusion system.

Decision-intervention interval in ruptured uteri in Ile-Ife, Nigeria

OBJECTIVE

To determine the decision-intervention interval in ruptured uterus with a view of overhauling the management strategy thereby improving the maternal and perinatal outcome.

DESIGN

Cross-sectional survey based on secondary data done between 1990-1999.

SETTING

Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria.

SUBJECTS

One hundred and two consecutive women who had uterine rupture.

RESULTS

The decision-surgical intervention interval ranged from 30 minutes to 4.5 hours. The major reason for delay was unavailability of compatible blood (88.2%), followed by lack of electricity (4.9%), unsterile instruments (3.9%), waiting for ambulance to get senior obstetricians (2.9%), delay in arrival of anaesthetist (1.9%) and neonatologists (1.9%). The peri-natal mortality rate (PNMR) was 843 per 1000 total births and maternal mortality rate (MMR) 4902 per 100,000 births.

CONCLUSION

The maternal and perinatal outcome in uterine rupture would be improved by early diagnosis and avoidance of preoperative delay through availability of essential obstetric services.

[Relationship of bilateral tubal occlusion with functional ovarian cysts]

The purpose was to determine the relation between functional ovary cysts (FOC) in patients with bilateral tubal occlusion (BTO) compared against a group of patients without the occlusion. Retrospective study, transversal and comparative in which 1,060 cases of patients that had pelvic ultrasounds were studied. 2 groups were formed: Group 1 with 356 patients with BTO, Group 2 without surgical sterilization history. In patients with BTO the FOC frequency was of 25.0% against a 15.7% detected in those without previous surgery. The frequency of FOC predominates in nulliparous patients without BTO (28.8%). On the age relation it is seen that en patients with BTO, the higher peak were functional cysts showed is on the 26 to 32 years old group. In patients without BTO the distribution is similar along the reproductive life with no domain of any age subgroup. The Xi'2 test showed that the difference of FOC in patients with BTO had a significant P < 0.05. BTO as antecedent is a factor that favors FOC and a cause-effect correlation exists. In women without. BTO age doesn't influence the incidence of FOC, and regarding the parity, FOC were observed more often in nulliparous patients with less that 30 years old. FOC can be related to other symptoms like an ovulation menstrual disorders, and pelvic ache. After this finding we must think about long-term complications resulted from bilateral tubal occlusion brings. We should also re-assess the surgical technique used since it can modify the living quality of the operated patients. BTO as a chosen procedure through informed consent, 0 offers in most of the cases more benefits than risks, nonetheless, there is the chance of consequence and long term symptoms and this should be informed to the patient.

Population, public health and tubal ligation in Vanuatu

The association between population growth and public health is often neglected. Between 1989 and 1999 Vanuatu's population grew by 30%. Unless this growth slows existing public health problems will worsen. To gain insight into family planning habits 111 ni-Vanuatu women undergoing tubal ligation were surveyed. 85% had 4, or more, children. Women resident on the outer islands had more children than those on the island containing the nation's capital. The implication is that ni-Vanuatu women perceive 4 children as desirable. With approximately half the population entering their reproductive years in the next decade this is too many to avoid a population explosion in Vanuatu. Public health campaigns must promote the benefits of a small family. Urgent education and widespread provision of effective family planning is required to avoid a future public health crisis. Aid donors need to be made aware of this as an absolute priority.

Female sterilisation through mini-laparotomy at Gondar College of Medical Sciences

OBJECTIVES

To describe the socio-demographic characteristics and clinical course and follow up of clients who have undergone voluntary surgical contraception (VSC) through minilaparotomy (mini-lap) under local anaesthesia (LA). Also, to evaluate the safety and method satisfaction, so as to forward recommendations for method utilisation in the Ethiopian context.

DESIGN

A case series design where pre- and post-operative conditions of clients coming for voluntary surgical contraception via mini-laparotomy were systematically analysed.

SETTING

Department of Obstetrics and Gynaecology, Gondar College of Medical Sciences, Gondar, Ethiopia.

SUBJECTS AND METHODS

Eighty two clients (median age of 33 years, range 25-40) who decided to use tubal sterilisation method of contraception from April 1993 to May 1995 were included in the study. A format prepared and distributed to VSC providing sites in Ethiopia by the Family Guidance Association of Ethiopia (FGAE) was used in collecting the necessary information, including informed consent of every client.

MAIN OUTCOME MEASURES

Previous knowledge of contraceptive methods, decision making for tubal sterilisation, size of incision, advantages of use of local anaesthesia in the local setting, duration of hospital stay, conditions on follow up.

RESULTS

Eighty two (55.4%) women underwent tubal sterilisation through mini-lap. The mean number of the live children per client was 6.2 +/- 1.7, with parity ranging from two to eleven children. Mothers with five or more children were 70 (85.4%). Among 69 mothers (84.1%), the last pregnancy outcome were live births. The average length of the time since making a decision not to have any more children was 2.5 +/- 2 years (median of one year). The rationales given were economic, ill health and completed family size. Regarding the pattern of decision making, in 77 (91.9%) clients both the couples were involved in decision making. All except two underwent the procedure under LA and no complication was encountered during surgery. Follow-up attendance was 100% in one-year period and nothing serious was reported. All reported to be satisfied with the method.

CONCLUSION

The study showed that early decision making by involving both couples other than proper case selection minimises regrets. The authors believe that tubal sterilisation through mini-lap under LA is an ideal method in developing countries where access to family planning and other reproductive health services are not widely available and where there is population explosion, less than 10% contraceptive prevalence rate and high maternal mortality.

Changes in the rate of tubal ligation done after cesarean section

OBJECTIVE

We studied tubal ligations done after cesarean section in a Spanish hospital during a 20-year period, in order to analyze changes in patient characteristics and indications for cesarean delivery.

STUDY DESIGN

We reviewed the clinical records, for the period from 1978 to 1997, of 1996 cases of cesarean section followed by tubal ligation in 108776 births in which the fetus weighed 1000 g or more.

RESULTS

During the 20-year period of study, the proportion of cesarean sections relative to vaginal deliveries increased, as did the frequency of cesarean section followed by tubal ligation relative to cesarean and vaginal deliveries. The proportion of women who underwent tubal ligation after a second cesarean section decreased from 60% during 1978-1982 to 5.6% during 1993-1997. The most frequent maternal pathology associated with gestation was previous cesarean section (60.5%), although 50% of the women had no underlying pathology.

CONCLUSIONS

In our setting, the rate of cesarean section followed by tubal ligation has been increasing steadily since the early 1980s. The proportion of women who requested tubal sterilization and who had only one living child, or who had had a previous cesarean birth, also increased.

Tubal sterilization in the United States, 1994-1996

CONTEXT

Although the number and rate of tubal sterilizations, the settings in which they are performed and the characteristics of women obtaining sterilization procedures provide important information on contraceptive practice and trends in the United States, such data have not been collected and tabulated for manyyears.

METHODS

Information on tubal sterilizations from the National Hospital Discharge Survey and the National Survey of Ambulatory Surgery was analyzed to estimate the number and characteristics of women having a tubal sterilization procedure in the United States during the period 1994-1996 and the resulting rates of tubal sterilization. These results were compared with those of previous studies to examine trends in clinical setting, in the timing of the procedure and in patient characteristics.

RESULTS

In 1994-1996, more than two million tubal sterilizations were performed, for an average annual rate of 1 1.5 per 1,000 women; half were performed postpartum and half were interval procedures (i. e., were unrelated by timing to a pregnancy). All postpartum procedures were performed during inpatient hospital stays, while 96% of interval procedures were outpatient procedures. Postpartum sterilization rates were higher than interval sterilization rates among women 20-29 years of age; interval sterilization procedures were more common than postpartum procedures at ages 35-49. Sterilization rates were highest in the South. For postpartum procedures, private insurance was the expectedprimary source of payment for 48% and Medicaid was expected to pay for 41 %; for interval sterilization procedures, private insurance was the expected primary source of payment for 68% and Medicaid for 24%.

CONCLUSIONS

Outpatient tubal sterilizations andprocedures using laparoscopy have increased substantially since the last comprehensive analysis of tubal sterilization in 1987, an indication of the effect of technical advances on the provision of this service. Continued surveillance of both inpatient and outpatient procedures is necessary to monitor the role of tubal sterilization in contraceptive practice.

Tubal sterilization and risk of breast cancer mortality in US women

OBJECTIVE

To investigate the hypothesis that tubal sterilization is associated with a reduced risk of breast cancer.

METHODS

We examined this hypothesis in a large prospective study of US adults. After 14 years of mortality follow-up, 3837 deaths from breast cancer were observed in a cohort of 619,199 women who were cancer-free at study entry in 1982.

RESULTS

Cox proportional hazards models (adjusted for multiple breast cancer risk factors) showed a significant inverse association between tubal sterilization and breast cancer mortality (adjusted rate ratio (RR) = 0.82, 95% confidence interval (CI) 0.70-0.96). Women who were sterilized before age 35 had a lower risk (adjusted RR = 0.69, 95% CI 0.53-0.88) than women who were sterilized at 35 years of age or older (adjusted RR = 0.92, 95% CI 0.75-1.13). Also, sterilizations performed before 1975 resulted in a lower risk (RR = 0.75, 95% CI 0.62-0.91) than those performed during or after 1975 (RR = 0.98, 95% CI 0.74-1.29), possibly reflecting the likelihood of greater tissue damage with earlier procedures.

CONCLUSIONS

These results suggest that tubal sterilization may lower subsequent risk of breast cancer, especially among women who are sterilized at a relatively young age. Additional studies are needed to confirm or refute these findings.

Union status, marital history and female contraceptive sterilization in the United States

CONTEXT

Much of what is known about the choice of sterilization as a contraceptive method is based on data from married women or couples. Because of increasing rates of cohabitation, divorce and repartnering, however, the relationship context in which sterilization decisions are made has changed.

METHODS

The 1995 National Survey of Family Growth includes the complete birth and union histories of 10,277 white, black and Hispanic women. The distribution of union status and marital history at the time of tubal sterilization was estimated for these three racial and ethnic groups among the 799 women who had had a tubal ligation in 1990-1995 before age 40. Cox proportional hazard regression models were used to estimate the effects of union status and marital history on the risk of tubal sterilization. The analysis controlled for the woman's age, parity, race and ethnicity education, region, experience of an unwanted birth and calendar period.

RESULTS

Among women who obtained a tubal sterilization, most whites (79%) and Hispanics (66%) were married when they had the operation, compared with only 36% of black women. At the time of their sterilization, 46% of black women had never been married. Among all women, regardless of race and ethnicity and net of all controls, the probability of tubal sterilization is about 25% lower for single, never-married women than for cohabiting or married women. Cohabitation does not reduce the likelihood in comparison to marriage, however. Higher rates of tubal sterilization among Hispanic women are accounted for by their higher parity at each age; differences in parity or marriage by race only partially account for the relatively higher rates of tubal sterilization among black women.

CONCLUSIONS

Because women currently spend greater proportions of their lives outside of marriage or in less-stable cohabiting partnerships than they did in the past, they are increasingly likely to make the decision to seek sterilization on their own. As a result, the gender gap in contraceptive sterilization will likely increase. The possibility of partnership change is an important consideration in choosing sterilization as a contraceptive method.

Profile of Indian women requesting reversal of sterilisation

This is a prospective clinical study carried out on 96 tubectomised women referred for microsurgical reversal to the Pandit BDS Postgraduate Institute of Medical Sciences, Rohtak and LHMC and SSKH, New Delhi. It was concluded that in developing countries high perinatal and child mortality rates are responsible for increased demands for reversal of sterilisation. Proper pre-operative counselling, age of the women, assessment of marital stability, family size and age of children are important before advocating sterilisation as a method of contraception.

Risk factors for uterine fibroids among women undergoing tubal sterilization

Uterine leiomyomas are reported to be the most common benign gynecologic tumors affecting premenopausal women, and they are often associated with considerable morbidity. The purpose of this study was to identify risk factors for uterine fibroids among women undergoing tubal sterilization. Cases comprised women aged 17-44 years whose uterine fibroids were first visualized at the time of tubal sterilization (1978-1979 or 1985-1987) or who reported a history of uterine fibroids (n = 317). Controls were randomly selected from women with no laparoscopic evidence of or history of fibroids (n = 1,268). Adjusted odds ratios were estimated using unconditional logistic regression separately for White (n = 1,235) and African-American (n = 350) women. Risk factors for White women included: age 40-44 years (odds ratio (OR) = 6.3; 95% confidence interval (CI): 3.5, 11.6), > or =5 years since last delivery (OR = 1.9; 95% CI: 1.1, 3.1), lifetime cigarette smoking of > or =1 pack/day (OR = 1.6; 95% CI: 1.1, 2.3), menstrual cycle length of >30 days (OR = 1.6; 95% CI: 1.1, 3.3), and menstrual bleeding for > or =6 days (OR = 1.4; 95% CI: 1.0, 2.0). Parous women were at reduced risk compared with nulliparous women (OR = 0.2; 95% CI: 0.1, 0.3). Advancing age was the only significant risk factor for African-American women (ages 40-44 years, OR = 27.5; 95% CI: 5.6, 83.6). Current oral contraceptive use and elective abortion were not associated with fibroids.

Factors affecting the selection of a reversible or an irreversible contraceptive method in a developing country

OBJECTIVES

To evaluate the factors that may affect the selection of a reversible or an irreversible contraceptive method.

METHODS

In an urban area of a developing country, demographic characteristics, educational and income levels, and previously used contraceptive methods were retrospectively reviewed for 3 years from the files of women who had chosen reversible or irreversible contraceptive methods. Student's t test and the chi2 test were used to analyze the data obtained from the two groups of women.

RESULTS

Out of a total of 8078 women, 595 (7.4%) selected surgical sterilization, while 7483 (92.6%) preferred reversible methods such as intrauterine devices (38.1%), combined oral contraceptives (13.9%), condoms (40%) and Norplant (0.6%). Compared to those who preferred reversible methods, the women with surgical sterilization had a higher mean age (33.9 +/- 4.2 years versus 29.6 +/- 3.9 years), mean gravidity (3.8 +/- 0.9 versus 2.3 +/- 1.2) and mean number of living children (2.6 +/- 0.8 versus 2.1 +/- 1.1) (p < 0.01). These women had also higher rates of high-school education (37.3% versus 30.1%) and previous modern contraceptive use (78.1% versus 71.2%) (p < 0.01). None of the women with surgical sterilization, but 1770 (33.0%) of those who chose reversible methods, had fewer than two living children.

CONCLUSIONS

These data suggest that irreversible contraceptive methods tend to be chosen by older women with higher educational levels, who have decided that their family is complete and who have at least two children.

Tubal sterilization: focus on the U.S. experience

OBJECTIVE

To review the frequency, effectiveness, and clinical sequelae of tubal sterilization with a focus on the U.S. experience.

DESIGN

A review of U.S. health care statistics and English-language literature using a MEDLINE search, bibliographies of key references, and U.S. government publications.

PATIENT(S)

Women seeking tubal sterilization.

INTERVENTION

Tubal sterilization.

MAIN OUTCOME MEASURE(S)

Effectiveness and long-term risks and benefits.

RESULT(S)

Half of the 700,000 annual bilateral tubal sterilizations (TS) are performed postpartum and half as ambulatory interval procedures. Eleven million U.S. women 15-44 years of age rely on TS for contraception. Failure rates vary by method with one third or more resulting in ectopic pregnancy. Reversal is most successful after use of methods that destroy the least tube. Evidence of menstrual or hormonal disturbance after TS is weak, although some studies find higher rates of hysterectomy among previously sterilized women. Decreased risk of subsequent ovarian cancer has been observed among sterilized women.

CONCLUSION(S)

Tubal sterilization is highly effective and safe. Failures, although uncommon, occur at higher rates than previously appreciated. Evidence for hormonal or menstrual changes due to TS is weak. Tubal sterilization is associated with decreased risk of ovarian cancer.

Women, men, and contraceptive sterilization

OBJECTIVE

To review the social and behavior contexts of decisions about contraceptive sterilization and to analyze factors associated with sterilization choices.

DESIGN

Multinomial logit regression of sterilization.

PATIENT(S)

Various subsamples as appropriate to specific analyses drawn from the 10,847 women interviewed in the 1995 National Survey of Family Growth, and the 5,227 men interviewed in the National Survey of Families and Households.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Tubal sterilization and vasectomy.

RESULT(S)

Surprisingly high proportions of recent tubal sterilizations were performed on unmarried women: 1 in 3 overall, 1 in 5 among white non-Hispanic women, and 2 in 3 among black women. Sterilization choice among continuously married couples also revealed large differences by race and ethnicity. Parity at the time of the last wanted birth is a major factor affecting sterilization choices, although significant effects were found as well as for a number of other variables, including age differences between spouses, education, and religion. Compared with other regions, the ratio of tubal sterilizations to vasectomies is extremely low in the Western region of the United States.

CONCLUSION(S)

Analysis of sterilization decisions must be based on time since the completion of childbearing. The findings call attention to the need for measuring variables that mediate observed associations with sterilization outcomes.

[Women and contraception: knowledge and use of contraceptive methods]

This article analyzes knowledge and use of contraceptive methods in women ages 10 to 49 years residing in the southern region of the city of São Paulo in 1992. A total of 1,157 childbearing-age women were studied, focusing on variables that might define them as to: knowledge in the use of contraceptive methods and reasons for choosing a given method. We observed that 86% of the women referred knowledge of some contraceptive method, while the most common was the pill (95.3%), followed by condoms (92.6%). Meanwhile, 14% of the interviewees denied knowledge of any contraceptive method. Of the sexually active women (66.4%), 34.9% reported never having used contraceptive methods. Of those who had, 35.3% used the pill, while 42.9% had resorted to sterilization. Only 5.2% used condoms. Despite the high level of knowledge concerning contraceptive methods, especially oral contraceptives and condoms, we observed limited use of same as compared to the high sterilization rate around the age of 27, thus leaving contraception limited to the pill and female sterilization.

Understanding the prevalence of female sterilization in rural south India

By analyzing the practice of female sterilization in rural Andhra Pradesh, in southern India, this article examines the role culture plays in demographic research. The popularity of female sterilization in rural Andhra Pradesh is shown to be intelligible if the symbolic value of a young mother's reproductive capacity is understood in terms of familial power relations. Through sterilization, young mothers can symbolically push their influential mothers-in-law toward old age, thus increasing their own relative prestige, and they can strive to control the ambiguity surrounding their reproductive functions. This study is based on 14 months of participant observation in three rural villages, a survey of 396 households, and unstructured interviews with 42 women and two men. It shows how demography and anthropology can be mutually supportive in their efforts to clarify population phenomena.

Sterilization and its consequences

The purpose of this review is to analyze critically the two techniques of sterilization (bilateral tubal ligation [BTL] and vasectomy) so that a physician may provide informed consent about methods of sterilization. A MEDLINE search and extensive review of published literature dating back to 1966 was undertaken to compare preoperative counseling, operative procedures, postoperative complications, procedure-related costs, psychosocial consequences, and feasibility of reversal between BTL and a vasectomy. Compared with a vasectomy, BTL is 20 times more likely to have major complications, 10 to 37 times more likely to fail, and cost three times as much. Moreover, the procedure-related mortality, although rare, is 12 times higher with sterilization of the woman than of the man. Despite these advantages, 300,000 more BTLs were done in 1987 than vasectomies. In 1987, there were 976,000 sterilizations (65 percent BTLs and 35 percent vasectomies) with an overall cost of $1.8 billion. Over $260 million could have been saved if equal numbers of vasectomies and BTLs had been performed, or more than $800 million if 80 percent had been vasectomies, as was the case in 1971. The safest, most efficacious, and least expensive method of sterilization is vasectomy. For these reasons, physicians should recommend vasectomy when providing counseling on sterilization, despite the popularity of BTL.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians

LEARNING OBJECTIVES

After completion of this article, the reader will be able to predict the failure rates and likelihood of successful reversal of tubal ligation and vasectomy; to recall the difference in cost between the two sterilization procedures, and to describe the short-term and long-term complications associated with each of the two methods of sterilization.

Hormone replacement therapy and risk of epithelial ovarian cancer

It has been suggested that oestrogen replacement therapy is associated with risk of epithelial ovarian cancer of the endometrioid type. Using data from an Australian population-based case-control study, the relation between unopposed oestrogen replacement therapy and epithelial ovarian cancer, both overall and according to histological type, was examined. A total of 793 eligible incident cases of epithelial ovarian cancer diagnosed from 1990 to 1993 among women living in Queensland, New South Wales and Victoria were identified. These were compared with 855 eligible female controls selected at random from the electoral roll, stratified by age and geographic region. Trained interviewers administered standard questionnaires to obtain detailed reproductive and contraceptive histories, as well as details about hormone replacement therapy and pelvic operations. No clear associations were observed between use of hormone replacement therapy overall and risk of ovarian cancer. Unopposed oestrogen replacement therapy was, however, associated with a significant increase in risk of endometrioid or clear cell epithelial ovarian tumours (odds ratio (OR) 2.56; 95% confidence interval (CI) 1.32-4.94). In addition, the risk associated with oestrogen replacement therapy was much larger in women with an intact genital tract (OR 3.00; 95% CI 1.54-5.85) than in those with a history of either hysterectomy or tubal ligation. Post-menopausal oestrogen replacement therapy may, therefore, be a risk factor associated with endometrioid and clear cell tumours in particular. Additionally, the risk may be increased predominantly in women with an intact genital tract. These associations could reflect a possible role of endometriosis in the development of endometrioid or clear cell ovarian tumours.

[Impact of contraceptive methods on women's lives: the case of tubal ligation]

This study focused on the long-term consequences of tubal ligation on women's lives. Women 30 to 49 years old living in Campinas, State of São Paulo (Brazil), were interviewed: 236 sterilized at least five years prior to the interview and 236 non-sterilized women. Their experiences with the currently used contraceptive methods were compared with regard to satisfaction, benefits, and damage attributed to the method, feelings of regret, and perception of effects on their health, body, menstruation, sex, affective and family life, job, studies, economic status, and self-esteem. Scores were created to compare the groups in relation to self-esteem, well-being/quality of life, relationship with partner, and gender issues. Satisfaction with the currently used contraceptive method was significantly higher among sterilized women, although they more frequently reported having regretted being sterilized at some moment in time. Relatively more sterilized women felt that the contraceptive method had improved their sex lives and economic status, while producing a negative effect on their menstruation. No significant difference was observed between the groups with regard to the scores studied.

[Reproductive characteristics of women from 15 to 49 years of age: comparative studies and planning for actions]

INTRODUCTION

The availability of socioeconomic, demographic and reproductive health data about women at national, regional and municipal levels allows comparisons between regions and may offer background information for planning actions of the Program of Integrated Assistance for Women's Health.

METHODS

A population-based cross-sectional study was carried out in Southern Brazil. Three thousand and two women aged 15 to 49 years living in an urban area in Pelotas, were selected for inclusion in the study. A structured questionnaire was used to collect the socioeconomic, demographic and reproductive characteristics. The analysis included comparison of means and proportions. In the sterilization analysis the data were controlled for age.

RESULTS

Nearly 56% of the women were married/in union and 35% were single. A third of them were housewives and 50% were wage workers. The mean of schooling was 8.5 years. Almost, half of the adolescents (15 to 19 years old) have an active sexual life, and of those 33% had already been pregnant. A high percentage of unwanted pregnancy was reported, mainly among younger women. Near the end of their reproductive life (women aged 45 to 49 years) the mean of children per woman was 2.4. The most prevalent methods were pill and sterilization. Among married women or those living in consensual union, 15% had been sterilized. The sterilization rate increased with age and attained nearly 25% of women aged over 35 years; 29.6% of sterilized women had had a stillborn child and 18.3% a pre-term baby; 20% of husbands/partners did not accept the use of any contraceptive method.

CONCLUSIONS

The study results confirm the need for additional attention to and development of special programs for adolescents, improvements in the access to services, increase in the use of the contraceptive options already available and research and programatic actions related to the theme "men/reproductive health.

Compliance with Papanicolaou smear screening following tubal ligation in women with cervical cancer

To evaluate patient compliance with Papanicolaou (Pap) smear screening after tubal ligation compared with other methods of birth control in patients who develop cervical cancer, a retrospective review of 262 women with cervical cancer diagnosed at age < or = 70 years was undertaken at the Albert Einstein College of Medicine from January 1987 to December 1995. Demographic data, stage of the disease, histologic type, history of smoking, history of sexually transmitted disease (STD), and birth control use were recorded. The Pap screening history was obtained from all the patients. Women who had a bilateral tubal ligation (BTL) were compared with those who did not have this form of birth control. The date and result of their last Pap test prior to their diagnosis of cervical cancer was noted. Two hundred fourteen women with cervical cancer were evaluable. The clinical stage, mean age, history of smoking, and history of STD were similar for both groups. Gravidity among the BTL group was higher than in the non-BTL group (p < 0.01). Forty-eight (22.4%) women had a previous BTL. Twenty-seven of these 48 patients (56.3%) did not have a Pap smear within 3 years prior to the diagnosis of cervical cancer. Of the 166 patients, 61 (36.7%) did not have a Pap test within 3 years (p < 0.05). Fourteen women (29.2%) in the tubal ligation group never returned for a Pap test following the BTL. An average of 6.2+/-5.9 years elapsed since the last Pap test in the BTL group, with 4.0+/-5.1 years in the nontubal ligation group (p < 0.05). There was a correlation between the number of years since BTL (14.2+/-7.7) to the number of years since the last Pap test (6.2+/-5.9) (p < 0.05). Women who have had a BTL should be considered high risk because of poor screening compliance. A Pap test every 3 years is not adequate in this high-risk population group. We advocate improved counseling regarding the importance of continued annual Pap screening for women who are considering tubal ligation.

Higher hysterectomy risk for sterilized than nonsterilized women: findings from the U.S. Collaborative Review of Sterilization. The U.S. Collaborative Review of Sterilization Working Group

OBJECTIVE

To compare the risk of hysterectomy among previously sterilized women and women whose husbands had undergone vasectomy, and to evaluate whether this risk differed by age at surgical procedure or by method of tubal occlusion.

METHODS

Our study population comprised 7718 women enrolled in a prospective, multicenter cohort study between 1978 and 1986. After stratifying by the woman's age at surgical procedure, we used the life-table approach and adjusted hazards ratios to examine whether the relative risk of hysterectomy during the 5 years after enrollment differed between the 7174 women who had been sterilized and the 544 women whose husbands had undergone vasectomy.

RESULTS

The 5-year cumulative probability of hysterectomy was 8% among the previously sterilized women and 2% among the women whose husbands had undergone vasectomy. Among women 34 years of age and younger at enrollment, sterilized women were 4.4 times as likely to have a hysterectomy as women whose husbands had undergone vasectomy (95% confidence interval [CI] 1.9, 10.0). Findings were similar for women 35 years of age and older (rate ratio = 4.6; 95% CI 1.4, 14.5). Each of the six most commonly used methods of tubal occlusion was associated with an increased risk of hysterectomy.

CONCLUSION

Women undergoing tubal sterilization were more likely than women whose husbands underwent vasectomy to undergo hysterectomy within 5 years after sterilization, regardless of age at sterilization. An increased risk of hysterectomy was observed for each method of tubal occlusion.
