Knowledge and attitudes about long-acting reversible contraception among Latina women who desire sterilization

BACKGROUND

There is growing interest in increasing the use of long-acting reversible contraception (LARC), and suggestions that such methods may serve as an alternative to sterilization. However, there is little information about whether women who do not want more children would be interested in using LARC.

METHODS

We conducted semistructured interviews with 120 parous Latina women in El Paso, Texas, who wanted a sterilization but had not obtained one. We assessed women's awareness of and interest in using the copper intrauterine device (IUD), levonorgestrel intrauterine system (LNG-IUS), and etonogestrel implant.

FINDINGS

Overall, 51%, 23%, and 47% of women reported they had heard of the copper IUD, LNG-IUS, and implant, respectively. More women stated they would use the copper IUD (24%) than the LNG-IUS (14%) or implant (9%). Among women interested in LARC, the most common reasons were that, relative to their current method, LARC methods were more convenient, effective, and provided longer-term protection against pregnancy. Those who had reservations about LARC were primarily concerned with menstrual changes. Women also had concerns about side effects and the methods' effectiveness in preventing pregnancy, preferring to use a familiar method.

CONCLUSIONS

Although these findings indicate many Latina women in this setting do not consider LARC an alternative to sterilization, they point to an existing demand among some who wish to end childbearing. Efforts are needed to improve women's knowledge and access to a range of methods so they can achieve their childbearing goals.

Hospital variation in postpartum tubal sterilization rates in California and Texas

OBJECTIVE

To estimate variation across hospitals in the rate of postpartum sterilization.

METHODS

All hospitals with deliveries in California and Texas in 2009 were included. Proportion of live singleton deliveries with postpartum sterilization was calculated by hospital, insurance status (Medicaid compared with private insurance), type of delivery, and state.

RESULTS

Within each insurance status in California and Texas, we found wide variations across hospitals in postpartum tubal sterilization rates. This variability was not explained by disparities in hospital cesarean delivery rates. Some, but not all, of this variation was attributable to the absence of sterilizations in Catholic hospitals. Overall, postpartum tubal sterilization rates were higher in Texas than in California (10.2% compared with 6.7%), and this difference was found among both public insurance and private insurance patients. Interval sterilizations were more frequent in California, but the difference was not large enough to offset the difference in postpartum sterilization.

CONCLUSIONS

The variation in postpartum tubal sterilization rates across hospitals is substantial and exists even among hospitals without religious affiliations. Large-scale studies are needed to assess the demand for, and the barriers to, obtaining postpartum sterilization.

Bayes plus Brass: estimating total fertility for many small areas from sparse census data

Estimates of fertility in small areas are valuable for analysing demographic change, and important for local planning and population projection. In countries lacking complete vital registration, however, small-area estimates are possible only from sparse survey or census data that are potentially unreliable. In these circumstances estimation requires new methods for old problems: procedures must be automated if thousands of estimates are required; they must deal with extreme sampling variability in many areas; and they should also incorporate corrections for possible data errors. We present a two-step procedure for estimating total fertility in such circumstances and illustrate it by applying the method to data from the 2000 Brazilian Census for over 5,000 municipalities. Our proposed procedure first smoothes local age-specific rates using Empirical Bayes methods and then applies a new variant of Brass's P/F parity correction procedure that is robust to conditions of rapid fertility decline. Supplementary material at the project website ( http://schmert.net/BayesBrass ) will allow readers to replicate all the authors' results in this paper using their data and programs.

Interest in over-the-counter access to oral contraceptives among women in the United States

BACKGROUND

A growing body of evidence indicates that over-the-counter (OTC) access to oral contraceptive pills (OCPs) is safe and effective.

STUDY DESIGN

We performed a nationally representative survey of adult women at risk of unintended pregnancy using a probability-based online panel. In November-December 2011, 2046 eligible women completed the survey. Weighted proportions were calculated, and logistic regression was used to identify covariates associated with support for and interest in using an OTC OCP.

RESULTS

A total of 62.2% said they were strongly (31.4%) or somewhat (30.9%) in favor of OCPs being available OTC. A total of 37.1% of participants reported being likely to use OCPs if available OTC, including 58.7% of current users, 28.0% using no method and 32.7% using a less effective method. Covariates associated with a higher odds of reporting interest in using OTC OCPs were younger age; being divorced, being separated or living with a partner (versus married); being uninsured or having private insurance (versus public insurance); living in the south (versus northeast); and current use of OCPs or less effective methods, or nonuse of contraception (versus use of another hormonal method or intrauterine device). Among respondents who said they were likely to use OTC OCPs, the highest amount they were willing to pay was on average $20.

CONCLUSIONS

US women are supportive of OTC access to OCPs, and many would obtain refills OTC or start using OCPs if they were available OTC.

Knowledge and beliefs about reproductive anatomy and physiology among Mexican-Origin women in the USA: implications for effective oral contraceptive use

Inherent in many reproductive health and family planning programmes is the problematic assumption that the body, its processes and modifications to it are universally experienced in the same way. This paper addresses contraceptive knowledge and beliefs among Mexican-origin women, based upon data gathered by the qualitative component of the Border Contraceptive Access Study. Open-ended interviews explored the perceived mechanism of action of the pill, side-effects, non-contraceptive benefits, and general knowledge of contraception. Findings revealed complex connections between traditional and scientific information. The use of medical terms (e.g. 'hormone') illustrated attempts to integrate new information with existing knowledge and belief systems. Conclusions address concerns that existing information and services may not be sufficient if population-specific knowledge and beliefs are not assessed and addressed. Findings can contribute to the development of effective education, screening and reproductive health services.

Frustrated demand for sterilization among low-income Latinas in El Paso, Texas

CONTEXT

Sterilization is the most commonly used contraceptive in the United States, yet access to this method is limited for some.

METHODS

A 2006-2008 prospective study of low-income pill users in El Paso, Texas, assessed unmet demand for sterilization among 801 women with at least one child. Multivariable logistic regression analysis identified characteristics associated with wanting sterilization. In 2010, at an 18-month follow-up, women who had wanted sterilization were recontacted; 120 semistructured and seven in-depth interviews were conducted to assess motivations for undergoing the procedure and the barriers faced in trying to obtain it.

RESULTS

At baseline, 56% of women wanted no more children; at nine months, 65% wanted no more children, and of these, 72% wanted sterilization. Only five of the women interviewed at 18 months had undergone sterilization; two said their partners had obtained a vasectomy. Women who had not undergone sterilization were still strongly motivated to do so, mainly because they wanted no more children and were concerned about long-term pill use. Among women's reasons for not having undergone sterilization after their last pregnancy were not having signed the Medicaid consent form in time and having been told that they were too young or there was no funding for the procedure.

CONCLUSIONS

Because access to a full range of contraceptive methods is limited for low-income women, researchers and providers should not assume a woman's current method is her method of choice.

Changes in service delivery patterns after introduction of telemedicine provision of medical abortion in Iowa

OBJECTIVES

We assessed the effect of a telemedicine model providing medical abortion on service delivery in a clinic system in Iowa.

METHODS

We reviewed Iowa vital statistic data and billing data from the clinic system for all abortion encounters during the 2 years prior to and after the introduction of telemedicine in June 2008 (n = 17,956 encounters). We calculated the distance from the patient's residential zip code to the clinic and to the closest clinic providing surgical abortion.

RESULTS

The abortion rate decreased in Iowa after telemedicine introduction, and the proportion of abortions in the clinics that were medical increased from 46% to 54%. After telemedicine was introduced, and with adjustment for other factors, clinic patients had increased odds of obtaining both medical abortion and abortion before 13 weeks' gestation. Although distance traveled to the clinic decreased only slightly, women living farther than 50 miles from the nearest clinic offering surgical abortion were more likely to obtain an abortion after telemedicine introduction.

CONCLUSIONS

Telemedicine could improve access to medical abortion, especially for women living in remote areas, and reduce second-trimester abortion.

Problems in using birth-history analysis to estimate trends in fertility

Summary The problem investigated is the adequacy of birth-history analysis as a method for estimating fertility change. The analysis demonstrates that inaccurate reporting of the dates of birth of live-born children can, under reasonable assumptions, significantly distort cohort fertility schedules in such a way that estimates of change in fertility will be biased in the direction of exaggerating declines in fertility. This kind of bias is shown to exist in fertility estimates obtained from survey data in El Salvador and Bangladesh. An important implication is that birth history questionnaires should begin with the most recent, rather than the earliest, event in a respondent's experience.

Reproductive health preventive screening among clinic vs. over-the-counter oral contraceptive users

BACKGROUND

Interest is growing in moving oral contraceptives over-the-counter (OTC), although concerns exist about whether women would continue to get preventive health screening.

STUDY DESIGN

We recruited cohorts of US-resident women who obtained oral contraceptives from US family planning clinics (n=532) and OTC from pharmacies in Mexico (n=514) and interviewed them four times over 9 months. Based on self-reports of having a Pap smear within 3 years or ever having had a pelvic exam, clinical breast exam and testing for sexually transmitted infections (STIs), we assessed the prevalence of preventive screening using Poisson regression models.

RESULTS

The prevalence of screening was high for both groups (>88% for Pap smear, pelvic exam and clinical breast exam and >71% for STI screening), while the prevalence ratios for screening were higher for clinic users, even after multivariable adjustment.

CONCLUSIONS

Results suggest that most women would obtain reproductive health preventive screening if oral contraceptives were available OTC, and also highlight the need to improve access to preventive screening for all low-income women.

The impact of outmigration of men on fertility and marriage in the migrant-sending states of Mexico, 1995-2000

Using the 2000 Mexican Census, we examined whether the level of migration was associated with total fertility and the proportion of women married in 314 municipalities from seven traditional sending states. Across these municipalities, we observe lower fertility in higher-migration areas. Municipalities in the quartile with the highest levels of migration have total fertility more than half a child lower than municipalities in the lowest migration quartile. However, there are no differences in marital fertility by level of migration, indicating that lower proportions of women married account for lower total fertility in high-migration municipalities. In municipal-level regression models, lower sex ratios are associated with a lower proportion of women married, while there is an inverse association between education and marriage. The level of migration also has an independent association with marriage, suggesting that there may be changing ideas surrounding family formation in high-migration areas.

Long Term Influences of Age-Education Transition on the Brazilian Labour Market

The objective of this study is to estimate the long term mean earnings of the male Brazilian population, taking into account the ageing process of the population and the increase in educational attainment. Using census data, household sample surveys, as well as population and education projections, estimates indicate that an ageing population and an increase in education will have a 2 percent impact on the annual growth of an average income in Brazil by 2050. The challenge for the future is to improve the proportion of the Brazilian population with completed college degrees.

Contraindications to progestin-only oral contraceptive pills among reproductive-aged women

BACKGROUND

Progestin-only oral contraceptive pills (POPs) have fewer contraindications to use compared to combined pills. However, the overall prevalence of contraindications to POPs among reproductive-aged women has not been assessed.

STUDY DESIGN

We collected information on contraindications to POPs in two studies: (1) the Self-Screening Study, a sample of 1267 reproductive-aged women in the general population in El Paso, TX, and (2) the Prospective Study of OC Users, a sample of current oral contraceptive (OC) users who obtained their pills in El Paso clinics (n=532) or over the counter (OTC) in Mexican pharmacies (n=514). In the Self-Screening Study, we also compared women's self-assessment of contraindications using a checklist to a clinician's evaluation.

RESULTS

Only 1.6% of women in the Self-Screening Study were identified as having at least one contraindication to POPs. The sensitivity of the checklist for identifying women with at least one contraindication was 75.0% [95% confidence interval (CI): 50.6%-90.4%], and the specificity was 99.4% (95% CI: 98.8%-99.7%). In total, 0.6% of women in the Prospective Study of OC Users reported having any contraindication to POPs. There were no significant differences between clinic and OTC users.

CONCLUSION

The prevalence of contraindications to POPs was very low in these samples. POPs may be the best choice for the first OTC oral contraceptive in the United States.

Religión e iniciación sexual premarital en México

El objetivo de este trabajo es analizar la asociación entre la afiliación religiosa y dos aspectos de la vida sexual de los jóvenes solteros en México: la iniciación y el uso de condón en la primera relación. Basándonos en la Encuesta Nacional de la Juventud 2005, describimos las diferencias en estos dos aspectos según la afiliación religiosa mediante la tabla de vida y estadística descriptiva respectivamente. Enseguida, empleamos el modelo de regresión de Cox para examinar la asociación entre religión y debut sexual, y el modelo de regresión logística para analizar la relación entre religión y uso de condón en dicho debut. Respecto de los católicos nominales y los jóvenes sin afiliación religiosa, los católicos practicantes y los protestantes evangélicos mostraron menores riesgos de iniciar su vida sexual y los evangélicos menores posibilidades de hacer uso de condón en el debut sexual.

Knox meets Cox: adapting epidemiological space-time statistics to demographic studies

Many important questions and theories in demography focus on changes over time, and on how those changes differ over geographic and social space. Space-time analysis has always been important in studying fertility transitions, for example. However demographers have seldom used formal statistical methods to describe and analyze time series of maps. One formal method, used widely in epidemiology, criminology, and public health, is Knox 's space-time interaction test. In this article, we discuss the potential of the Knox test in demographic research and note some possible pitfalls. We demonstrate how to use familiar proportional hazards models to adapt the Knox test for demographic applications. These adaptations allow for nonrepeatable events and for the incorporation of structural variables that change in space and time. We apply the modified test to data on the onset offertility decline in Brazil over 1960-2000 and show how the modified method can produce maps indicating where and when diffusion effects seem strongest, net of covariate effects.

Clinic versus over-the-counter access to oral contraception: choices women make along the US-Mexico border

OBJECTIVES

As part of the Border Contraceptive Access Study, we interviewed oral contraceptive (OC) users living in El Paso, Texas, to assess motivations for patronizing a US clinic or a Mexican pharmacy with over-the-counter (OTC) pills and to determine which women were likely to use the OTC option.

METHODS

We surveyed 532 clinic users and 514 pharmacy users about background characteristics, motivations for choosing their OC source, and satisfaction with this source.

RESULTS

Older women and women born and educated in Mexico were more likely to patronize pharmacies. Cost of pills was the main motivation for choosing their source for 40% of pharmacy users and 23% of clinic users. The main advantage cited by 49% of clinic users was availability of other health services. Bypassing the requirement to obtain a doctor's prescription was most important for 27% of pharmacy users. Both groups were very satisfied with their pill source.

CONCLUSIONS

Women of different ages, parities, and educational levels would likely take advantage of an OTC option were OCs available at low cost. Improving clinic provision of OCs should be considered.

Mapping the Timing, Pace, and Scale of the Fertility Transition in Brazil

Between 1960 and 2000, fertility fell sharply in Brazil, but this transition was unevenly distributed in space and time. Using Bayesian spatial statistical methods and microdata from five censuses, we develop and apply a procedure for fitting logistic curves to the fertility transitions in more than 500 small regions of Brazil over this 40-year period. Doing so enables us to map the main features of the Brazilian fertility transition in considerable detail. We detect early declines in some regions of the country and document large differences between early and late transitions in regard to both the initial level of fertility and the speed of the transition. We also use our results to test hypotheses regarding changes in the level of development at the onset of the fertility transition and identify a temporary stall in the Brazilian transition that occurred in the late 1990s.

[Demographic Dynamics and Educational Inequality in Mexico]

This paper seeks to explore the link between educational processes and Mexico's demographic dynamic. In the tradition of thought on population and development, it has been hypothesized that the population growth rate, family size and migration influence the accumulation of human capital among the school-age population. This study explores the link between the academic performance of youth between the age of 14 and 23 and the youth dependency ratio, teenage fertility and internal and international migration, using data aggregated at the municipal level for the year 2000. The analysis uses indicators on the educational supply at the municipal level based on the administrative statistics of the Public Education Secretariat (SEP).

Perceptions of the safety of oral contraceptives among a predominantly Latina population in Texas

BACKGROUND

Fear of side effects and previous negative experiences are common reasons for contraceptive nonuse.

STUDY DESIGN

We collected information about perceptions of oral contraceptive (OC) safety from 1271 women 18-49 years old in El Paso, TX, and compared their responses to a medical evaluation by a nurse practitioner. We also asked participants about their interest in obtaining OCs over the counter (OTC).

RESULTS

Among 794 women potentially at risk of unintended pregnancy, 56.0% said that OCs were medically safe for them. Reasons given for OCs being unsafe were related to fears of side effects and prior negative experiences rather than true contraindications. Older women and participants recruited at the less affluent recruitment site were significantly more likely to report that OCs were medically unsafe for them (p<.05). Nonusers who thought OCs were medically unsafe for them were as likely to be medically eligible for use as current hormonal users. Among nonusers or nonhormonal users and potential OC candidates (n=601), 60.2% said they would be more likely to use OCs if they were available OTC.

CONCLUSIONS

Women's perception of OC safety does not correlate well with medical eligibility for use. More education about the safety and health benefits of hormonal contraception is needed. OTC availability might contribute to more positive safety perceptions of OCs compared to a prescription environment.

Religious Affiliation, Ethnicity, and Child Mortality in Chiapas, México

We investigate whether there is a relationship between religious affiliation and child mortality among indigenous and nonindigenous groups in Chiapas, México. Our analysis relies on Brass-type estimates of child mortality by ethnicity and religious affiliation and multivariate analyses that adjust for various socioeconomic and demographic factors. The data are from the 2000 Mexican Census 10 percent sample. Among indigenous people, Presbyterians have lower rates of child mortality than Catholics. However, no significant differentials are found in child mortality by religious affiliation among nonindigenous people. The indigenous health ministry of the Presbyterian Church and the social and cultural transformations that tend to accompany religious conversion may have an impact on child survival among disadvantaged populations such as the indigenous people in Chiapas.

Adolescent fertility and religion in Rio de Janeiro, Brazil in the year 2000: the role of Protestantism

Social transformations in Brazil in recent years have included a substantial increase in adolescent fertility, a dramatic rise in membership of Protestant religious denominations, and an accompanying decline in the number of Catholics. We used the 2000 Brazil Census to examine differentials in fertility and family formation among adolescents living in Rio de Janeiro by the following religious denominations: Catholic; Baptist; other mainline Protestant; Assembly of God Church; Universal Church of the Kingdom of God; other Pentecostal Protestant; and no religion. Results from logistic regression models show that the majority of the Protestants are at a lower risk of adolescent fertility than Catholics, and that among adolescents who have had a child, most Protestants are more likely than Catholics to be in a committed union. Our findings offer some support for the hypothesis that Protestant churches are more effective than the Catholic Church in discouraging premarital sexual relations and childbearing among adolescents.

Women's autonomy and scheduled cesarean sections in Brazil: a cautionary tale

BACKGROUND

In Brazil, one-fourth of all women deliver in the private sector, where the rate of cesarean deliveries is extremely high (70%). Most (64%) private sector cesareans are scheduled, although many women would have preferred a vaginal delivery. The question this study addresses is whether childbearing women were induced to accept the procedure by their physicians, and if so, how?

METHODS

Three face-to-face structured interviews were conducted with 1,612 women (519 private sector and 1,093 public sector) early in pregnancy, approximately 1 month before their due date, and approximately 1 month postpartum. For all private sector patients having a scheduled cesarean section, women's self-reported reasons given for programming surgical delivery were classified into three groups according to obstetrical justification.

RESULTS

After loss to follow-up (19.2% of private sector and 34.4% of public sector), our final sample included 1,136 women (419 private sector and 717 public sector). Compared with public sector participants in the final sample, on average, private sector participants were older by 3.4 years (28.7 vs 25.3 yr), had 0.4 fewer previous deliveries (0.6 vs 1.0), and had 3.4 more years of education (11.0 vs 7.6 yr). The final samples also differed slightly with respect to preference for vaginal delivery: 72.3 percent among those in the private sector and 79.6 percent in public sector. The cesarean section rate was 72 percent in the private sector and 31 percent in the public sector. Of the women with reports about the timing of the cesarean decision, 64.4 percent had a scheduled cesarean delivery in the private sector compared with 23.7 percent in the public sector. Many cesarean sections were scheduled for an "unjustified" medical reason, especially among women who, during pregnancy, had declared a preference for a vaginal delivery. Among 96 women in this latter group, the reason reported for the procedure was unjustified in 33 cases. On the other hand, more cesarean deliveries were scheduled for "no medical justification," including physician's or the woman's convenience, among women who preferred to deliver by cesarean (35/65). The incidence of real medical reasons for a scheduled cesarean section diagnosed before the onset of labor among private sector patients who had no previous cesarean birth and who wanted a vaginal delivery was 13 percent (31/243).

CONCLUSIONS

The data suggest that doctors frequently persuaded their patients to accept a scheduled cesarean section for conditions that either did not exist or did not justify this procedure. The problem identified in this paper may extend well beyond Brazil and should be of concern to those with responsibility for ethical behavior in obstetrics.

Over-the-Counter Access, Changing WHO Guidelines, and Contraindicated Oral Contraceptive Use in Mexico

This study examines the prevalence of contraindications to the use of oral contraceptives in Mexico by sociodemographic characteristics and by whether this family planning method was obtained with or without a doctor's prescription. Using data on smoking behavior and blood-pressure measurements from the 2000 Mexican National Health Survey, the authors found that, under the 1996 World Health Organization (WHO) medical eligibility guidelines, the prevalence of contraindications is low and that no significant differences in contraindications exist at any level between those who obtain oral contraceptives at clinics and those who obtain them at pharmacies. In 2000, however, WHO substantially revised its criteria regarding the level of hypertension that would constitute a contraindication for oral contraceptive use. Applying the new guidelines, the authors found that 10 percent of pill users younger than 35 and 33 percent aged 35 and older have health conditions that are either relative or absolute (Category 3 or 4) contraindications. The relevance of these findings to the larger debate concerning screening and over-the-counter access to oral contraceptives is discussed.

Empirical bayes estimation of demographic schedules for small areas

In this article, we analyze empirical Bayes (EB) methods for estimating small-area rate schedules. We develop EB methods that treat schedules as vectors and use adaptive neighborhoods to keep estimates appropriately local. This method estimates demographic rates for local subpopulations by borrowing strength not only from similar individuals elsewhere but also from other groups in the same area and from regularities in schedules across locations. EB is substantially better than standard methods when rates have strong spatial and age patterns. We illustrate this method with estimates of age-specific fertility schedules for over 3,800 Brazilian municipalities.
