Use of a Spacing Method Before Sterilization Among Couples in Kerala, India
Context: Many couples in India never use a reversible method to delay or space births, and instead adopt sterilization as their first and only method. Little is known about the factors that distinguish sterilized couples who have used spacing methods from those who go directly to using a permanent method.
Methods: Data on 2,029 ever-married women protected by sterilization are taken from the part of the 1992-1993 Indian National Family Health Survey that was conducted in the state of Kerala. Multivariate logistic regression techniques are used to assess the socioeconomic, demographic and behavioral characteristics that determine prior temporary method use among sterilized couples.
Results: Once all significant variables are controlled for, higher educational attainment (of either partner) independently increases the likelihood that a couple will have used a method to delay or space births, as does middle socioeconomic status. That likelihood is also significantly higher among respondents who experienced an abortion, among Christian women and among those who were older than age 25 when either they or their partner were sterilized. However, the likelihood of temporary method use before sterilization is significantly reduced among respondents who preferred shorter birth intervals and among relatively older women (age 31 and older). The median interval between the first and second children born to sterilized couples who had ever used a reversible method was longer than that among children born to couples who had relied only on sterilization (32 months vs. 26 months).
Conclusions: In Kerala, both small family size ideals and a desire to shorten the period of exposure to the risk of pregnancy might explain the tendency for couples to go directly to sterilization at a relatively young age and bypass temporary method use altogether. An approach that emphasizes clients' choice of methods and high-quality services that cater to their needs would enhance the use of methods to space births. =paragraph
One of the principal objectives of family planning programs, as endorsed by Programme of Action adopted in Cairo at the 1994 International Conference on Population and Development, is to enable couples to decide freely the number, timing and spacing of their births; to ensure that they make informed choices; and to make available a full range of safe and effective methods.1 Of this range of methods, however, sterilization (mainly female sterilization) is the most commonly used method, especially in developing countries.2 When couples achieve their desired family size, most choose to undergo sterilization, since it is considered the most effective and safest method to stop childbearing. In some countries where the use of modern contraceptive methods is uncommon, sterilization is often the first and sole method of family planning that couples use to control their family size.3
In India, people often equate the term family planning with sterilization, although government policies aim to promote the use of reversible methods.4 Several factors account for sterilization's widespread use in India. Government incentives offered both to potential users and to providers throughout the late 1960s and the 1970s* undoubtedly contributed to the predominance of permanent methods over temporary methods.
In response to the Cairo recommendations and to the results of internal evaluations, and because of reports that the program was administered unscrupulously and that the numbers of acceptors were inflated, the Indian government introduced a target-free approach in April 1996. Under the new target-free philosophy, grassroots health workers are charged with offering family planning services to couples who are interested both in spacing their children and in limiting family size.
Nevertheless, use of reversible methods remains comparatively poor. For example, as of March 1995, temporary methods accounted for just 35% of all method use in India.5 (Moreover, only 3% of couples relied on condoms in 1992-1993,6 an alarming fact given the rapidly increasing rates of HIV and other reproductive tract infections in India.) Such limited reliance on spacing methods increases the risk of relatively short birth intervals, which in turn increase the risk of premature delivery and of low birth weight.7 In addition, rates of infant and child mortality, particularly neonatal mortality, are higher among children born after short birth intervals.8 The health of both the mother and the child is enhanced with adequate birthspacing intervals, whether they are achieved through natural postpartum infecundability, through prolonging that period through breastfeeding or through the effective use of spacing methods.
At the national level, the 1992-1993 National Family Health Survey (NFHS) indicated that 31% of couples of reproductive age were protected by sterilization, and that among these couples, only 22% had ever used a reversible method before the operation.9 The use of spacing methods prior to sterilization varies widely by state, however, ranging from a low of 7% among sterilized couples in Andhra Pradesh, to 39% and 43% in Kerala and West Bengal, respectively, and to a high of 56% in Assam (see Table 1).

This wide variation by state reflects India's enormous socioeconomic, demographic, geographic and cultural diversity. The low use of temporary methods in the majority of Indian states may be attributable to a lack of knowledge about and access to such methods.10 In addition, a strong preference among couples for sterilization as soon as they achieve their desired family size might shorten the period of reproductive exposure, thereby lowering the likelihood of spacing method use. Son preference and the desire for a family of at least three children have also influenced the sterilization rate in India.11 Further, India's family planning program has largely failed to encourage the use of reversible methods, particularly among young women (those aged 15-30) who are in the most fertile years of their reproductive period.12
Attempts to promote increased reliance on temporary methods could benefit from data on what distinguishes women who use other methods before sterilization from those who never use any method but a permanent one. We chose to study contraceptive behavior among women in one especially developed Indian state, Kerala.
The southwestern state of Kerala has already completed the last stage of its demographic transition: Among India's 25 states, Kerala holds the unique distinction of having demographic indicators that closely resemble those of a developed country.13 As of 1992-1993, it had achieved a total fertility rate of 2.0 lifetime births per woman, a low infant mortality rate of 17 infant deaths per 1,000 live births, a sex ratio of 1,036 females per 1,000 males, and a female literacy rate of 86% (according to the 1991 census).14 Moreover, official government data indicate that in 1990-1991, Kerala had the highest level of overall contraceptive use of any state--60% of couples, compared with 44% for the country as a whole.15
Nonetheless, Kerala also follows the national pattern of comparatively little reliance on reversible methods. The 1992-1993 NFHS indicated that in Kerala, fewer than two-fifths of couples protected by sterilization had ever used a spacing method.16 Another study, conducted in Kerala in 1992, put this proportion at only 20%.17 Thus, in this context, we assess the socioeconomic, demographic and behavioral characteristics that either motivate or inhibit couples from practicing contraception to delay or space births before they ultimately adopt sterilization.
DATA AND METHODOLOGY
The Kerala data come from the NFHS conducted in the state from October 1992 to February 1993. That survey collected individual-level data on 4,332 ever-married women aged 13-49, based on representative samples from 4,387 households. Nearly one-half of these women--47% or 2,029 women--were protected by either their own or their partner's sterilization; these women form our study population.
The NFHS asked women about any contraceptive used by themselves or by their partners. Although many women reported having used more than one reversible method, we were concerned with ever-use only. We conducted multivariate logistic regression analyses to uncover the factors that determined the likelihood that couples had ever used a temporary method before sterilization. We chose explanatory variables based on an extensive review of the literature. These included eight demographic and socioeconomic variables--the respondent's age, her place of residence, her and her husband's educational attainment, her religion, her standard of living18 (as measured by a Standard of Living Index§), her exposure to the mass media and her employment status at the time of the interview.
We also examined eight reproductive behavior and attitude variables, such as the respondent's experience of abortion,** the source of sterilization, her age at the time of tubal ligation or vasectomy, whether she regretted the sterilization, her approval of family planning, her ideal birth interval, her ideal family size and the number of children ever born. (We excluded a variable on knowledge of family planning, because knowledge of at least one method is almost universal in Kerala.19)
We created three separate logistic regression models to analyze the effects of the significant variables (based on chi-square tests) on the likelihood of ever using a reversible contraceptive before sterilization. The first controlled for the woman's demographic and socioeconomic characteristics only, the second controlled for the woman's reproductive behavior and attitudes only (along with age, which was controlled for in all three models), and the third considered all of the variables that were significant in the first two models.
We also used NFHS data to examine how ever-use of a temporary method affected the length of birth intervals among Kerala women protected by sterilization.
Overall, the women in the sample were predominantly Hindu (64%), lived in rural areas (71%), did not work outside the home (67%) and were moderately well educated (23% had attended middle school and 15% had attended high school, see Table 2). Thirty-eight percent of the couples had elected to be sterilized once they had had two children, an additional 34% did so after having had three children, 13% did so after four children and 14% did so after having five or more. Most of these women (61%) had never used any method other than sterilization (not shown).
About 39% of couples had used some reversible method before sterilization, with no significant difference between urban and rural women (Table 3). Ever-use of a spacing method did vary significantly by the seven remaining socioeconomic characteristics, however. For example, respondents aged 30 and younger were significantly more likely than older women to have ever used a method other than sterilization. Spacing method use also rose steadily with increasing education (of either partner), as 66% of women who had completed high school had ever used a temporary method, compared with 24% of women who had had no schooling. Only 26% of Muslim women had ever used a reversible method, compared with 39% of Hindu women and 47% of Christian women. The tendency to have used a spacing method before sterilization also increased with the standard of living score and with exposure to the media. However, the proportion with experience using a reversible method was significantly lower among women who were working at the time of the survey than among those who were not.

Ever-use of a spacing method varied significantly by each of the eight reproductive behavior variables, except for regret over sterilization. For example, women who had had an induced abortion or miscarriage were more likely than those who had not to have used a reversible method. Ever-use of a spacing method was also significantly higher among those who relied on the private sector than among those who used the public sector for their sterilization, and among women who were comparatively older at the time of their or their partner's sterilization.
Ever-use of a spacing method was significantly higher among women who said they approved of family planning than among those who said they did not. As expected, women who considered birth intervals of more than 24 months to be ideal were significantly more likely than those who preferred shorter intervals to have ever used a reversible method. Moreover, the proportion who had used a temporary method was significantly higher among women whose ideal family size consisted of two children or fewer than among those who viewed families of more than two to be ideal. Previous use of temporary methods decreased with increasing number of children ever born.
We also observed a difference in the length of birth intervals between users and nonusers of a reversible method before sterilization (Table 4). For example, intervals between first and second births were six months longer among couples who had ever used a spacing method than among those who had not (median lengths of 32 months and 26 months, respectively). This difference narrowed to only two months, however, when we compared the second-birth intervals among users and nonusers of a reversible method before sterilization (median lengths of 29 months and 27 months, respectively).
|Table 4. Median duration (in months) of birth intervals, and percentage distribution of women protected by sterilization by length of birth interval, all according to previous method use and type of birth interval|
|Length of interval (in months)||All||Users||Nonusers|

|BETWEEN 2ND AND 3RD BIRTHS||(N=1,210)||(N=426)||(N=784)|
Moreover, among women with two children, only 28% of those who had ever used a reversible method before sterilization had a birth fewer than 24 months after a first child, compared with 40% among women who had never used a temporary method.
In the first of the three multivariate logistic analyses, which controlled for the socioeconomic variables and age only, both the husband's and the wife's educational attainment were significantly associated with the use of spacing methods before sterilization (Table 5). For example, respondents who had completed middle school were twice as likely (odds ratio of 2.1), and high school-educated women were 3.7 times as likely, to have practiced contraception before adopting sterilization as were those who had had no schooling. There was no significant difference in that likelihood, however, when women with primary schooling were compared with women who had never been to school. The husband's education had similar independent effects on the likelihood of temporary method use, although the magnitude of the resulting odds ratios was lower.

Once all the socioeconomic variables were controlled for, Christian women were 1.4 times as likely as Hindu women to have ever used a method other than sterilization. There were no significant differences, however, between Hindu and Muslim women.
Women whose standard of living index was in the medium range were about 50% more likely than those who scored low on that index to have ever used a temporary method. There was no significant difference in that likelihood between women with a high standard of living index score and those with a low one.
Women who were older than age 30 were 25% less likely to have used a method before sterilization than were younger women. Women's employment status and their exposure to the media had no independent effect on the likelihood of temporary method use.
Once the effects of age and reproductive attitudes and behavior variables were controlled for, women who had ever had an abortion were significantly more likely to have used a method prior to sterilization than were those who had not undergone an abortion (odds ratio of 1.8). A few other variables--approving of family planning and being 25 or older at the time of the sterilization--also independently raised the likelihood of using a method before sterilization.
Other variables, however, significantly decreased the likelihood of reversible method use in the second model. For example, women older than 30 at the time of the interview were about 40% less likely to be users than those aged 30 and younger. Moreover, couples who opted for a public-sector source of sterilization services were 37% less likely to have used a spacing method than were those who relied on a private provider. Women who considered a birth interval of 24 months or shorter to be ideal were 47% less likely than those whose ideal interval was more than 24 months to have used a method; and those believing that more than two children would be ideal were 29% less likely. Finally, although women who had had at least two children before adopting sterilization were somewhat less likely to have ever used a reversible method, this association was not statistically significant.
The variables that proved significant in either of the first two models (with age being significant in both) were then entered into a third model that controlled for all 11 significant variables simultaneously. In this final model, all variables except ideal family size and source of sterilization retained their significance. The effect of the respondent's current age retained its significance in all three of the models.
DISCUSSION AND CONCLUSIONS
In Kerala, several factors play an important role in a couple's decision to avoid using spacing methods and go directly to relying on a permanent method. It seems that if couples intend to become sterilized, they do not bother using methods to space their children.
The finding that better-educated men and women are significantly more likely than their less-educated peers to have used a reversible method corroborates data from earlier studies in India and in other countries, which found lower levels of temporary method use and of contraceptive knowledge among sterilized women with comparatively less schooling.20
Schooling imparts accurate knowledge about birthspacing and the need to use spacing methods; thus, even if less-educated persons are aware that such methods exist, they may be inadequately informed about them or may be reluctant to use them out of fear of side effects, perceived inaccessibility or opposition by a spouse or other relative. Ignorance of the range of temporary methods available might also prompt couples to forgo their use.21 Educated persons may also communicate and demand family planning services more easily than noneducated persons. Reliance on reversible methods could increase if health workers at the grassroots level were to disseminate more information about them.
In the state of Kerala, Christians are more likely than those of other religions to practice family planning before becoming sterilized; this finding reflects Christians' overall higher levels of method use in the state.22 However, even Muslim women in Kerala have relatively high levels of contraceptive use, compared with Muslim women in other states.23
Our analysis also uncovered another important association--the reduced likelihood of early use of reversible methods among sterilized couples who scored low on the standard of living index. This finding might lead one to ask whether couples with a low standard of living choose sterilization over a reversible method because of incentives or pressure from health workers. Although studies have not yet validated this hypothesis,24 research has shown that economic incentives triggered a demand for sterilization in Kerala.25
The age at which couples choose to undergo sterilization is mediated through their knowledge of the procedure and their desire to stop childbearing, together with the motivating efforts of health workers. The recent trend toward adoption of sterilization at progressively younger ages reflects small family-size ideals and a desire for shorter periods of exposure to the risk of unwanted childbearing, once couples achieve their desired family size of two children.26 However, such sole reliance on sterilization might result in shorter birth intervals. Indeed, we found that couples who had relied solely on sterilization had shorter birth intervals than those who had ever used a method other than sterilization (i.e., a median interval between first and second births of 26 months versus one of 32 months).
We also found that, in the analysis that controlled for reproductive attitudes and behavior only, the likelihood of using a spacing method was lower among respondents who obtained their sterilization through the public sector. In India, the private sector is known to deliver higher quality services than the public sector, which suffers problems of distribution and supply.27 However, this problem is less severe in Kerala than in the rest of the country, because of that state's comparatively better transportation networks and communication facilities.28
This study also revealed that respondents who had experienced an induced or spontaneous abortion were more likely than those who had not to have used a spacing method. Women who have had an abortion might be more motivated than others to defer subsequent births and be more likely to visit health clinics, where they would learn about spacing methods.29 Moreover, women who had had an abortion might even have considered the abortion itself as a method of birth spacing. An earlier study pointed out that the high demand for abortion services in India reflects a high unmet need for spacing methods in that country.30 However, this unmet need is probably not as strong in Kerala as in the rest of India, since that state has a relatively high rate of health institution utilization.31
The overall poor performance of India's family planning program, coupled with people's perceptions that the quality of care is substandard,32 could explain the low use of spacing methods before sterilization in Kerala. There is a dire need to reconsider the existing family welfare services in Kerala. The program needs to shift its focus to "choice and service" and to steer clear of coercive approaches--that is, couples should be granted the right to freely decide their choice of method without fear of repercussions.
The predominance of traditional methods among couples who used a method prior to sterilization points to the need to popularize more effective modern methods. Efforts need to be made to expand the range of spacing methods available and to improve the quality of services. Currently, the spacing methods offered mainly through primary health centers include the IUD, the pill and the condom. While such methods are available free of cost at public-sector facilities, users must pay a fee at a private-sector center. We believe that public-sector facilities in Kerala could improve their image and raise the quality of their services by introducing a token or nominal fee.
The recently introduced target-free approach and the new national Reproductive and Child Health Services program may succeed in popularizing spacing methods in Kerala. The success of this new focus and program will be assessed in the forthcoming round of the NFHS surveys in Kerala, as well as in the rest of the states and in India as a whole.

Contexte: En Inde, de nombreux couples ne pratiquent jamais de méthode réversible apte à différer ou espacer leurs naissances; ils recourent plutôt à la stérilisation comme seule et unique méthode. Il existe peu de données sur les facteurs qui distinguent les couples stérilisés ayant eu recours aux méthodes d'espacement et ceux ayant directement choisi une méthode permanente.
Méthodes: Les données relatives à 2.029 femmes mariées protégées par la stérilisation ont été extraites de la partie de l'enquête nationale sur la santé de la famille (Indian National Family Health Survey) menée en 1992-1993 dans l'état de Kerala. Les techniques de régression logistique multivariée sont utilisées pour évaluer les caractéristiques socioéconomiques, démographiques et comportementales qui déterminent le recours antérieur à une méthode temporaire parmi les couples stérilisés.
Résultats: Après contrôle de toutes les variables significatives, l'accès à un niveau d'instruction plus élevé (par l'un ou l'autre des partenaires) accroît de manière indépendante la probabilité du recours antérieur à une méthode de recul ou d'espacement des naissances, de même qu'un rang socioénomique plus élevé. Cette probabilité se révèle également significativement supérieure parmi les répondants ayant vécu un avortement, parmi ceux stérilisés dans un établissement du secteur privé et parmi ceux âgés de plus de 25 ans au moment de la stérilisation de l'un des partenaires. L'intervalle médian entre les premier et deuxième enfants nés de couples stérilisés qui avaient jamais pratiqué de méthode réversible était plus long qu'entre les enfants nés de couples passés directement à la stérilisation (32 par rapport à 26 mois).
Conclusions: Une campagne de sensibilisation de la population pourrait accroître en Inde la prévalence des méthodes temporaires et leur efficacité. Une approche axée sur le choix et l'offre de prestations dans le cadre de soins de haute qualité permettrait d'accroître davantage la pratique des méthodes d'espacement des naissances.
