Accelerating India's fertility decline: the role of temporary contraceptive methods

This report summarizes findings from the 1992-93 National Family Health Survey of India, on fertility and contraceptive use. Fertility declined about 2 children/woman during 1972-92. The total fertility rate in 1992-93 was 3.4 children/woman. The average desired number of children among ever married women aged 13-49 years was 2.9 children/woman. Among the 41% of women who used contraception, 76% relied on sterilization. 27% of currently married women of reproductive age were sterilized, and 3% had husbands who were sterilized. 20% of women had an unmet need for family planning. 64% of all women currently using temporary methods wanted no more children. 11% desired more children after an interval of 2 or more years. 9% desired a stop to childbearing. Women not currently using contraception and intending to use in the future preferred sterilization (59%) or a temporary method (36%). Currently, 24% of contraceptive users rely on temporary methods. It is likely that meeting unmet need for temporary methods would substantially increase contraceptive use. Women who were not using any method averaged 2.7 children, while sterilized women had 4.0 children. Women who used traditional methods averaged 2.8 children. Women using temporary methods averaged 2.6 children. It is unlikely that sterilization would further reduce fertility much below levels already reached. Women sterilized before the age of 24 years tended to have modest sized families, but most women were sterilized at older ages. Currently, only 10% of married women use temporary methods, and only 6% use a modern method.     

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, S?o 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.     

Provision of female sterilization in Ribeirao Preto, Sao 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.     

Contraceptive patterns among women and men in León, Nicaragua

The aim was to study the contraceptive patterns among men and women in León, Nicaragua. A questionnaire about sexual, contraceptive, reproductive and socioeconomic issues was directed to 7,789 households including 22% of all women of the municipality aged 15–49 years (n = 10,867). A subsample of 388 men and 413 women aged 15–49 years was drawn at random. Refusals were less than 2%. Private interviews revealed that among fertile women who had been sexually active within the last three months, non-pregnant and wishing to avoid pregnancy, 77% were contracepting. Female sterilization was the most common contraceptive method (39%), followed by intrauterine device (16%). Even though around 60% of women at some time had tried oral contraceptives, only 13% of contraceptors used them currently. The rhythm and interruption methods together constituted only 4%. Condom use was low and mainly occasional. Contraceptive use in sexually active women aged 15–44 years was lower among those having lower education, living in rural areas, and living under poverty conditions. The predominance of female sterilization and the occasional condom use—mainly reported by men—reflects a situation of relative male control over contraception and reproduction. This probably originates from “machista” values where men having many children with different women are considered strong. There was also a significantly higher use of contraceptives among the better-off women and men compared with the extremely poor. The situation of many poor women, in a country with limited contraceptive services, is worrving considering that abortion is illegal and the threat of HIV epidemic is growing. The situation for adolescents is particularly problematic with low experience in contraceptive use.     

Female sterilization-acceptor characteristics

This article reports the findings of a study concerning the socioeconomic characteristics of women undergoing sterilization in India. Only 23% of India's 119 million couples use some form of contraception, but of these, 87% rely on male or female sterilization. It is estimated that some 20 million married women of reproductive age have been sterilized. This study examined the cases of 800 women who underwent sterilization at the Department of Obstetrics and Gynecology of the Kamla Nehru Hospital, Shimla from February 1986 to April 1987. In addition to investigating the socioeconomic characteristics of the women, the study also focused on the knowledge and practice of other contraceptive methods, the motivating factors, and the reasons for undergoing sterilization. The study found that 68% of the women were from rural areas and 32% from urban areas. 71% of the women belonged to lower social classes -- only 40% of the women were literate. 98% of the women were Hindus, the remaining 2% belonging to other religious groups. 72.9% of the women were between the ages of 20 and 33 years, the mean age at sterilization being 27.5 years. While 77.3% of the women has 2 or 3 living children, only 2.6% had only 1 living child. 71.2% of the women had both male and female children, and 9.2% had only female children. Concerning the use of contraception, only 22% of the women had practiced contraception prior to the operation. 70% of the women reported being self-motivated, while 26% said that they had been motivated by a family planning worker or hospital staff member. 96.5% of the women reported multiparity and/or socioeconomic reasons for undergoing the procedure, while 3.5% of the sterilizations were performed for therapeutic reasons.

Trends in contraceptive patterns and behaviors during a period of fertility transition in China: 1988-2006

BackgroundThis paper explores how contraceptive patterns and behaviors changed during the course of China's population transition and a period of low fertility from 1988 to 2006.Study DesignBased on data from Chinese nationwide surveys of family planning and reproductive health undertaken in 1988, 1997, 2001 and 2006, this study uses a multinomial logit model to analyze changes in, regional differences in and determinants of contraceptive behaviors during this period.ResultsThe overall prevalence of contraceptive use among married women aged 15–49 years changed little during these 20 years, holding steady at about 90%. However, there were notable changes in the method mix: the predominant methods used were the long-term methods of the intrauterine device (IUD) and female sterilization, and contraceptive use gradually shifted from sterilization to IUDs and condoms. There existed a close relationship between contraceptive methods used and sociodemographic characteristics. Hans, rural, old and less educated women are more likely to use sterilization, while minorities, urban, young and educated women are more likely to use IUDs.ConclusionThere are marked changes in the method mix among different demographic groups during the course of China's population transition and a period of low fertility. The findings indicate that future works aimed at promoting reproductive health should be diverse among different populations.     

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.     

Demographic trends of tubal sterilization in the United States 1970-75.

An estimated 2,300,000 women in the United States underwent tubal sterilizations in 1970-1975. During this period the rate of tubal sterilizations per 1,000 women 15-44 years of age rose from 4.7 to 11.7. We studied the influence on sterilization trends of four demographic variables: age, region of residence, race, and marital status. Women 25-34 years of age were twice as likely to be sterilized as older or younger women. Rates were about 40 per cent lower in the West than in the rest of the country. In 1970 rates for non-white women were double those for Whites. Rates for Whites rose faster than those for non-Whites, however, and by 1975 the rates were similar for the 2 races. Non-Whites still tended to be sterilized about one year younger than Whites, and marked regional differences existed in the race-specific rate trends. Rates rose more sharply for previously married women than for currently married women; by 1975 rates for these two groups were similar. Never married women had rates about 1/7 of those of currently married and previously married women. Among the never married, tubal sterilization rates for non-Whites were nine times higher than those for Whites.     

Contraceptive use and sterilization among Puerto Rican women.

A comparison of contraceptive use in the early to mid-1980s among married Puerto Rican women aged 15-49 in the New York City area reveals that island-born Puerto Rican women living in New York rely on female sterilization to nearly the same extent as do women living in Puerto Rico (45% and 41%, respectively) and that mainland-born Puerto Rican women use sterilization as much as do all women in the United States (19% for both groups). Puerto Rican women in New York use reversible methods to a greater extent than do women in Puerto Rico (22% v. 16%), but to a lesser extent than do all women in the United States (37%). Although mainland-born Puerto Rican women in New York use reversible methods more than do island-born women in New York (42% v. 23%), they tend not to adopt these methods to the same extent as do all U.S. women during the early reproductive years, when education and employment are critical to socioeconomic attainment.     

Why are rates of sterilization in decline? A pilot study designed to explore reasons for declining female sterilization in Scotland

BACKGROUND: In the last decade, female sterilization had been in decline throughout the UK. It is not clear whether fewer women are requesting sterilization or whether the universal enthusiasm for long-acting reversible methods is leading health professionals to discourage women from being sterilized. Since correct and consistent use of alternative, reversible contraceptive methods depends somewhat on their acceptability, it is important to determine whether women are being refused sterilization or whether they are freely choosing other methods. This study aims to explore whether female sterilization is being widely considered as a contraceptive method, the reasons for choosing or rejecting it, and whether women are being discouraged by health professionals from being sterilized. STUDY DESIGN: A self-completed questionnaire survey among 205 women aged 30 to 50 years who felt that their family was complete attending a family planning clinic in Scotland. RESULTS: Of the 203 women included in the study, 151 (74.4%) had heard of female sterilization, 90 had discussed it with someone (60%) and 87 (58%) had considered it as a contraceptive option. Of the 56 women who consulted their family doctor about sterilization, almost half (27; 48%) were not referred to a hospital and fewer than one (17, 30.4%) in three of them was eventually sterilized or had arrangements in place to get it done. Free-text comments from the women revealed a variety of reasons for not choosing female sterilization and suggested that some women are being deterred from sterilization. CONCLUSION: The study suggests that some women are being actively encouraged by health professionals to use long-acting reversible contraceptive methods and discouraged from choosing sterilization. However, other women recognize for themselves the wisdom of keeping their fertility options open.

Risk factors and predictors of induced abortion: a population-based study

This study aimed to identify key risk factors and predictors of induced abortion. A cross-sectional population-based study was conducted with a representative sample of 3,002 women 15 to 49 years of age in southern Brazil, randomly assigned to answer questions on induced abortion using either the ballot-box method or the indirect questioning method. Socioeconomic, demographic, and reproductive data were obtained through a pre-coded questionnaire. Data analysis used epidemiological statistical inferences and Bayes' theorem to calculate a posteriori probability. Induced abortion was strongly associated with fetal loss for all age groups. In adolescents, the main predictors were low socioeconomic level, low schooling, elevated school drop-out, and knowledge of a large number of contraceptive methods. For all other women, socioeconomic characteristics and skin color were not associated with abortion. For women aged 20 to 49 years, marital status and reproductive characteristics, including knowledge of contraceptive methods, were the most frequent risk factors and predictors of induced abortion.     

Premarital fertility in rural South Africa: a challenge to existing population policy

The age pattern of fertility in a rural area of South Africa under demographic surveillance (Agincourt subdistrict) was investigated over the 1992-97 period. The total fertility rate (TFR) averaged 3.3 births per woman of reproductive age over the period, a major drop from earlier estimates in the same area (6.0 births in 1970-74). Age-specific fertility rates showed an atypical bimodal pattern. They were decomposed into two components of similar magnitude: premarital fertility (among women aged 12-26) and marital fertility (among women aged 15-49). The decomposition revealed the two underlying modes: a mode of premarital fertility (among women aged 18-20) and a mode of marital fertility (among women aged 28-30). Premarital fertility accounted for 21 percent of all births and for 47 percent of births among women aged 12-26. This pattern of high premarital fertility appears to reflect a low incidence of contraceptive use before the first birth, especially among adolescents, a low prevalence of abortion, and a high contraceptive prevalence thereafter. This finding calls for a reorientation of the family planning policy, which until now has targeted married women and women who have been pregnant once, but has failed to address the contraceptive needs of young women before their first pregnancy, especially adolescents.     

Contraceptive methods and adequacy of hormonal oral contraceptive use in the city of Pelotas, Rio Grande do Sul, Brazil: 1992-1999

A cross-sectional study was conducted to assess contraceptive methods and the adequacy of oral contraceptive use by women aged 20 to 49 years in the city of Pelotas. The results were compared with another cross-sectional study performed in 1992. A sample was randomly selected, including 766 women aged 20 to 49 years. Some 495 of the sample (64.6%) used a contraceptive method, in the following order: oral contraceptives (55.4%), surgical sterilization (22.2%), condoms (10,5%), and IUD (7.7%). Among users of oral contraceptives, 62 (22.2%) had some contraindication. Incorrect use of contraceptive methods was associated with age but not with socioeconomic status. As compared to the previous study, there was a reduction in the use of oral contraceptives. Meanwhile, other methods such as surgical sterilization, condoms, and IUD were used more frequently than in 1992.     

Post-marketing surveillance of Norplant contraceptive implants: I. Contraceptive efficacy and reproductive health

The subject of this study to examine the safety and contraceptive efficacy of Norplant, we undertook a 5-year study of follow-up of women initiating use of Norplant, intrauterine device (IUD) or sterilization in eight developing countries. Women attending family clinics were enrolled if they consented and were medically eligible to use Norplant, IUD, or female sterilization. Women who chose to initiate use of IUDs or surgical sterilization served as controls and were frequency matched in 5-year age-bands with women who chose to use Norplant. At admission women had a physical examination, and their medical histories, demographic, and socio-economic characteristics were recorded. Follow-up visits were scheduled in the first 6 weeks after admission and semi-annually thereafter for 5 years irrespective of change of contraceptive method. Incidence rate ratios of health events were estimated for initial and current contraceptive method use. This paper reports reproductive health events and contraceptive efficacy. Altogether, 7,977 women initiating use of Norplant, 6,625 of IUD, and 1,419 of surgical sterilization were admitted. Their mean ages at initiation were 28.5, 28.5, and 29.6 years, respectively. More than 99% were married or cohabiting, and parous. Five-year follow-up was completed by 94.6% of the women. By the end of 5 years, the mean duration of first segment use per initiator was 4.16 years for Norplant, 4.10 years for IUDs, and 4.96 years for sterilization accounting for 39,337 woman-years for Norplant, 31,915 for IUDs, and 7,071 for sterilization. The study accumulated 78,323 woman-years of observation. Pearl pregnancy rates for Norplant, copper IUDs and female sterilization were 0.27, 0.88, and 0.17 per 100 woman-years, respectively. Users of Norplant, copper IUDs, and sterilization had rates of ectopic pregnancy of 0.30, 0.68, and 0.13 per 1,000 woman-years, respectively. Major health events related to the reproductive system were rare. Rates of acute PID were significantly lower among Norplant users than IUD users (p = 0.004). The rate of ovarian enlargement was significantly higher in Norplant users than controls (p <0.001), but not rates of hospitalization for this condition. Vaginitis and vaginal discharge, and low abdominal pain were significantly less frequent in Norplant users than in the other groups. Bleeding disturbances were more frequent among Norplant users than controls but not anemia. The study confirms the high contraceptive efficacy of Norplant, copper IUDs, and female sterilization. The incidence rates of major reproductive health problems were low. There was no significant excess of serious reproductive morbidity among users of Norplant compared to users of IUDs and sterilization.     

Factors associated with reproductive options in HIV-infected women

A cross-sectional study was conducted in Campinas, Brazil, in HIV-infected women to evaluate factors associated with reproductive practices. A total of 112 HIV-infected women, 13 to 45 years old, with previous sexual experience were included in the study. Three groups were compared: pregnant women aware of their infection before current pregnancy, sterilized women who had made their reproductive choice after serodiagnosis and women using any reversible contraceptive method. Fisher's Exact Test and multivariate correspondence analysis were used in the statistical analysis. Among women interviewed, 23% were pregnant, 18% had been sterilized and 59% were using a reversible contraceptive method. Being younger was associated with reproductive practices that preserved the possibility of having a child. Reversible contraceptive users had fewer pregnancies and more often reported a desire to have children compared to the other groups. Partner's desire for parenthood was associated with pregnant and sterilized women. The clinical condition of the women and their partners, the serologic status of partner nor counseling about contraceptive choices influenced reproductive practices.     

Public policy and female sterilization in Costa Rica

For 20 years, female sterilization has been increasing in popularity as a contraceptive method in Costa Rica. However, contraceptive sterilization has never been allowed explicitly under Costa Rican law. In 1976 the Costa Rican National Assembly instituted more stringent guidelines regarding medical sterilizations in order to eliminate contraceptive sterilizations, which had been occurring under relatively loose interpretations of national policy. Data from the 1976 National Fertility Survey and the 1981 Contraceptive Prevalence Survey indicate that the change in policy had only a short-term effect. Period sterilization rates fell substantially after 1976 but rebounded considerably by 1980, and the estimate of the proportion of married women who will ultimately be sterilized was approximately .5 for the periods both before and after 1976.     

The Rise of Female Sterilization: A Closer Look at Colombia

Objective In the 1970s, OCPs and IUDs were the most popular contraceptive methods in Colombia. According to data from the most recent Demographic and Health Survey (DHS), sterilization has become the most common form of birth control in Colombia. This study aims to examine the characteristics of Colombian women desiring long-acting contraception. Methods This study uses the 2005 and 2010 Colombian DHS dataset. Women who choose long-acting contraception were divided into those using female sterilization and those using long-acting reversible contraception (LARC). A multivariate logistic regression model was used to compare demographic and social determinants of contraceptive choice among reproductive age women seeking long-acting contraception between the years 2005 and 2010. Results Among women using a long-acting contraceptive method in 2010, compared to 2005, women were significantly more likely to be sterilized (1.14 OR, 95% CI 1.09–1.18) and less likely to use LARC (0.88 OR, 95% CI 0.85–0.92). Of women seeking long-acting contraception, those exposed to a family planning provider were less likely to undergo sterilization (0.54 OR, 95% CI 0.51–0.58) and more likely to use LARC (1.84 OR, 95% CI 1.73–1.96). When compared to all contraceptive users, younger women and women with less than two children were more likely to use LARC than sterilization. Conclusion Between 2005 and 2010, an increase in the proportion of contracepting women being sterilized in Colombia occurred. Our findings suggest that exposure to a family planning provider and appropriate contraceptive counseling appears to be key determinants of long-acting contraceptive choice. To improve use of long-acting, effective contraception, efforts should be made to increase access to family planning providers.
