History of unintended pregnancy and patterns of contraceptive use among racial and ethnic minority women veterans

BACKGROUND

Nearly half of all pregnancies in the United States each year are unintended, with the highest rates observed among non-Hispanic black and Hispanic women. Little is known about whether variations in unintended pregnancy and contraceptive use across racial and ethnic groups persist among women veteran Veterans Affairs users who have more universal access than other populations to health care and contraceptive services.

OBJECTIVES

The objectives of this study were to identify a history of unintended pregnancy and describe patterns of contraceptive use across racial and ethnic groups among women veterans accessing Veterans Affairs primary care.

STUDY DESIGN

Cross-sectional data from a national random sample of women veterans (n = 2302) aged 18-44 years who had accessed Veterans Affairs primary care in the previous 12 month were used to assess a history of unintended pregnancy (pregnancies reported as either unwanted or having occurred too soon). Any contraceptive use at last sex (both prescription and nonprescription methods) and prescription contraceptive use at last sex were assessed in the subset of women (n = 1341) identified as being at risk for unintended pregnancy. Prescription contraceptive methods include long-acting reversible contraceptive methods (intrauterine devices and subdermal implants), hormonal methods (pill, patch, ring, and injection), and female or male sterilization; nonprescription methods include barrier methods (eg, condoms, diaphragm), fertility-awareness methods, and withdrawal. Multivariable logistic regression models were used to examine the relationship between race/ethnicity with unintended pregnancy and contraceptive use at last sex.

RESULTS

Overall, 94.4% of women veterans at risk of unintended pregnancy used any method of contraception at last sex. Intrauterine devices (18.9%), female surgical sterilization (16.9%), and birth control pills (15.9%) were the 3 most frequently used methods across the sample. Intrauterine devices were the most frequently used method for Hispanic, non-Hispanic white, and other non-Hispanic women, while female surgical sterilization was the most frequently used method among non-Hispanic black women. In adjusted models, Hispanic women (adjusted odds ratio, 1.60, 95% confidence interval, 1.15-2.21) and non-Hispanic black women (adjusted odds ratio, 1.84, 95% confidence interval, 1.44-2.36) were significantly more likely than non-Hispanic white women to report any history of unintended pregnancy. In the subcohort of 1341 women at risk of unintended pregnancy, there were no significant racial/ethnic differences in use of any contraception at last sex. However, significant differences were observed in the use of prescription methods at last sex. Hispanic women (adjusted odds ratio, 0.51, 95% confidence interval, 0.35-0.75) and non-Hispanic black women (adjusted odds ratio, 0.69, 95% confidence interval, 0.51-0.95) were significantly less likely than non-Hispanic white women to have used prescription contraception at last sex.

CONCLUSION

Significant racial and ethnic differences exist in unintended pregnancy and contraceptive use among women veterans using Veterans Affairs care, suggesting the need for interventions to address potential disparities. Improving access to and delivery of patient-centered reproductive goals assessment and contraceptive counseling that can address knowledge gaps while respectfully considering individual patient preferences is needed to support women veterans' decision making and ensure equitable reproductive health services across Veterans Affairs.

Global Contraceptive Failure Rates: Who Is Most at Risk?

Contraceptive failure is a major contributor to unintended pregnancy worldwide. DHS retrospective calendars, which are the most widely used data source for estimating contraceptive failure in low-income countries, vary in quality across countries and surveys. We identified surveys with the most reliable calendar data and analyzed 105,322 episodes of contraceptive use from 15 DHSs conducted between 1992 and 2014. We estimate contraceptive method-specific 12-month failure rates. We also examined how failure rates vary by age, education, socioeconomic status, contraceptive intention, residence, and marital status using multilevel piecewise exponential hazard models. Our failure rate estimates are significantly lower than results from the United States and slightly higher than previous studies that included more DHS surveys, including some with lower-quality data. We estimate age-specific global contraceptive failure rates and find strong, consistent age patterns with the youngest users experiencing failure rates up to ten times higher than older women for certain methods. Failure also varies by socioeconomic status, with the poorest, and youngest, women at highest risk of experiencing unintended pregnancy due to failure.

Contraceptive use in Latin America and the Caribbean with a focus on long-acting reversible contraceptives: prevalence and inequalities in 23 countries

BACKGROUND

The rise in contraceptive use has largely been driven by short-acting methods of contraception, despite the high effectiveness of long-acting reversible contraceptives. Several countries in Latin America and the Caribbean have made important progress increasing the use of modern contraceptives, but important inequalities remain. We assessed the prevalence and demand for modern contraceptive use in Latin America and the Caribbean with data from national health surveys.

METHODS

Our data sources included demographic and health surveys, multiple indicator cluster surveys, and reproductive health surveys carried out since 2004 in 23 countries of Latin America and the Caribbean. Analyses were based on sexually active women aged 15-49 years irrespective of marital status, except in Argentina and Brazil, where analyses were restricted to women who were married or in a union. We calculated contraceptive prevalence and demand for family planning satisfied. Contraceptive prevalence was defined as the percentage of sexually active women aged 15-49 years who (or whose partners) were using a contraceptive method at the time of the survey. Demand for family planning satisfied was defined as the proportion of women in need of contraception who were using a contraceptive method at the time of the survey. We separated survey data for modern contraceptive use by type of contraception used (long-acting, short-acting, or permanent). We also stratified survey data by wealth, area of residence, education, ethnicity, age, and a combination of wealth and area of residence. Wealth-related absolute and relative inequalities were estimated both for contraceptive prevalence and demand for family planning satisfied.

FINDINGS

We report on surveys from 23 countries in Latin America and the Caribbean, analysing a sample of 212 573 women. The lowest modern contraceptive prevalence was observed in Haiti (31·3%) and Bolivia (34·6%); inequalities were wide in Bolivia, but almost non-existent in Haiti. Brazil, Colombia, Costa Rica, Cuba, and Paraguay had over 70% of modern contraceptive prevalence with low absolute inequalities. Use of long-acting reversible contraceptives was below 10% in 17 of the 23 countries. Only Cuba, Colombia, Mexico, Ecuador, Paraguay, and Trinidad and Tobago had more than 10% of women adopting long-acting contraceptive methods. Mexico was the only country in which long-acting contraceptive methods were more frequently used than short-acting methods. Young women aged 15-17 years, indigenous women, those in lower wealth quintiles, those living in rural areas, and those without education showed particularly low use of long-acting reversible contraceptives.

INTERPRETATION

Long-acting reversible contraceptives are seldom used in Latin America and the Caribbean. Because of their high effectiveness, convenience, and ease of continuation, availability of long-acting reversible contraceptives should be expanded and their use promoted, including among young and nulliparous women. In addition to suitable family planning services, information and counselling should be provided to women on a personal basis.

'I wanted to enjoy our marriage first… but I got pregnant right away': a qualitative study of family planning understandings and decisions of women in urban Yogyakarta, Indonesia

BACKGROUND

Despite several decades of investment into family planning and maternal health systems strengthening, Indonesia's maternal mortality ratio remains among the highest in Southeast Asia. Among postpartum women unmet need for family planning is greater than at any other time, thus there is great potential to improve the reproductive health outcomes of Indonesian women through enhanced postpartum family planning access. This article explores the socially embedded nature of family planning choices in the Indonesian context, drawing on the experiences of a sample of urban dwelling and predominantly middle class women.

METHODS

This was an ethnographic study which explored the reproductive experiences of women residing in Yogyakarta City, and Sleman and Bantul regencies. Fieldwork was undertaken over 18 months from September 2014 to March 2016. This article draws on 31 in-depth interviews (IDIs) conducted with 20 women aged 21 to 38 years who had given birth less than two years prior.

RESULTS

Though there was great variance across women's reproductive trajectories, the majority had limited understandings of family planning, especially in relation to contraception. Societal norms pertaining to women's fertility and reproduction underpinned women's desires to become pregnant soon after marriage. Normative ideals concerning family size and the composition of families underpinned women's desires for a maximum of two to three children, with at least one child of each sex. Negotiations concerning timing of pregnancies and family size occurred within spousal relationships. The majority of women were using some form of fertility control to prevent or space pregnancies, with method choice decisions often informed by family members, friends and family planning providers. Quality of care among family planning providers was often lacking, perpetuating misinformation, and women's choices were not always respected.

CONCLUSIONS

Our analysis reveals the socially embedded nature of women's postpartum family planning understandings and choices, and the ways in which social and relational factors sometimes constrain and at other times support women's reproductive agency. We identify key areas for health sector reform to enhance women's understandings of postpartum family planning and improve family planning quality of care.

Effects of male literacy on family size: A cross sectional study conducted in Chakwal city

OBJECTIVE

To determine the effects of male education on family size, the desired family size, knowledge and use of contraception and opinion about female education.

METHODS

The cross-sectional study was carried out in Chakwal city, Punjab, Pakistan, from June to October 2009. A pre-tested questionnaire was used for data collection. The respondents were males and data on their demographics, age at marriage, actual and desired family size, knowledge about methods of contraception, and opinion about female education was collected. SPSS 15 was used for statistical analysis.

RESULTS

Out of the 178 respondents, 52(29.2%) were illiterate and 126(70.8%) were educated. Among the educated, 97(77%) were in favour of small families compared to only 10(19.2%) of the uneducated males (p< 0.001). Besides, 118 (93.6%) educated males were aware of any method of contraception. The most important source of awareness was television 45(37.8%) followed by lady health visitors 40(33.9%). Among the respondents, 38(21.3%) were not using any contraceptive method because they considered it unIslamic, 16(9.1%) had fear of side effects, 57(32.0%) were desirous of large families, while 67(37.6%) had other reasons, like trying to conceive. Among the uneducated males, 17(32.7%) didn't discuss any family planning issue with their wives compared to 14(11.3%) of educated males (p< 0.001).

CONCLUSIONS

Educational status of the males had an effect on the desired family size, contraceptive use and views in favour of female education.

Comparison of Abstinence and Coital Frequency Between 2 Natural Methods of Family Planning

INTRODUCTION

The length of periodic abstinence, due to overestimation of the fertile phase of the menstrual cycle, is often a cause for dissatisfaction, discontinuation, and user error with natural family planning (NFP) methods. The objective of this research was to compare the length of required abstinence (ie, estimated fertility) and coital frequency between 2 NFP methods.

METHODS

This was an analysis of data from a 12-month prospective comparison study in which participants were randomized into either an electronic hormonal fertility monitor (EHFM) group or a cervical mucus monitoring (CMM) group-both of which included a fertility algorithm as a double check for the beginning and end of the estimated fertile window. The number of days of estimated fertility and coitus was extracted from each menstrual cycle of data, and t tests were used to compare the means of these 2 variables between the 2 NFP methods.

RESULTS

The study involved 197 women (mean [SD] age 29.7 [5.4]) who used the EHFM to estimate the fertile window and 160 women (mean [SD] age 30.4 [5.3]) who used CMM to estimate the fertile window. They produced 1,669 menstrual cycles of data. After 12 months of use, the EHFM group had statistically fewer days of estimated fertility than the CMM group (mean [SD] days, 13.25 [2.79] vs 13.68 [2.99], respectively; t = 2.07; P = .039) and significantly more coitus (mean [SD] coital acts, 4.22 [3.16] vs 4.05 [2.88], respectively; t = 1.17; P = .026).

DISCUSSION

The use of the EHFM seems to provide more objectivity and confidence in self-estimating the fertile window and using nonfertile days for intercourse when avoiding pregnancy.

Social network- and community-level influences on contraceptive use: evidence from rural Poland

The diffusion of 'modern' contraceptives-as a proxy for the spread of low-fertility norms-has long interested researchers wishing to understand global fertility decline. A fundamental question is how local cultural norms and other people's behaviour influence the probability of contraceptive use, independent of women's socioeconomic and life-history characteristics. However, few studies have combined data at individual, social network and community levels to simultaneously capture multiple levels of influence. Fewer still have tested if the same predictors matter for different contraceptive types. Here, we use new data from 22 high-fertility communities in Poland to compare predictors of the use of (i) any contraceptives-a proxy for the decision to control fertility-with those of (ii) 'artificial' contraceptives-a subset of more culturally taboo methods. We find that the contraceptive behaviour of friends and family is more influential than are women's own characteristics and that community level characteristics additionally influence contraceptive use. Highly educated neighbours accelerate women's contraceptive use overall, but not their artificial method use. Highly religious neighbours slow women's artificial method use, but not their contraceptive use overall. Our results highlight different dimensions of sociocultural influence on contraceptive diffusion and suggest that these may be more influential than are individual characteristics. A comparative multilevel framework is needed to understand these dynamics.

A hospital-based comparative study of the knowledge, attitudes and practices of family planning among women belonging to different socio-economic status

OBJECTIVE

To assess the knowledge, attitudes and practices of family planning among women belonging to different socio-economic status.

METHODS

A cross sectional study was conducted in the outpatient department of three hospitals of Ziauddin University based on the socioeconomic divide. Total 351 married females of reproductive age group with at least one child were selected after informed consent through non probability convenience sampling. Data was analyzed by using SPSS version 21.

RESULTS

The preferred method of contraception in all three groups was a male condom30.9%. The upper socioeconomic group relied more on the modern methods of contraception 92% while the middle socioeconomic group relied on modern 71.7% as well as natural methods of contraception 28.3%. Use of contraceptives was comparatively lower in the low socioeconomic group 19.5%. Lower socioeconomic group also had the most children per family with mean and standard deviation of 3.6±2.3 and also had the highest number of desired children with mean and standard deviation of 4±1.4. The general reasons for avoiding contraceptives were difficulty in getting pregnant (11.1%), the want for more children (10.2%), infrequent sexual intercourse (10.0%) and fear of side effects (6.9%).

CONCLUSIONS

Awareness of contraception was found lowest in the lower socioeconomic class, with the elite class using a high percentage of contraceptives.

The role of the Standard Days Method in modern family planning services in developing countries

BACKGROUND

The mere availability of family planning (FP) services is not sufficient to improve reproductive health; services must also be of adequate quality. The introduction of new contraceptive methods is a means of improving quality of care. The Standard Days Method (SDM) is a new fertility-awareness-based contraceptive method that has been successfully added to reproductive health care services around the world.

CONTENT

Framed by the Bruce-Jain quality-of-care paradigm, this paper describes how the introduction of SDM in developing country settings can improve the six elements of quality while contributing to the intrinsic variety of available methods. SDM meets the needs of women and couples who opt not to use other modern methods. SDM providers are sensitised to the potential of fertility-awareness-based contraception as an appropriate choice for these clients. SDM requires the involvement of both partners and thus offers a natural entry point for providers to further explore partner communication, intimate partner violence, condoms, and HIV/STIs.

CONCLUSION

SDM introduction broadens the range of FP methods available to couples in developing countries. SDM counselling presents an opportunity for FP providers to discuss important interpersonal and reproductive health issues with potential users.

[Family planning methods based on fertility awareness]

The desire to limit fertility is recognized both by individuals and by nations. The concept of family planning is based on the right of individuals and couples to regulate their fertility and is based in the area of health, human rights and population. Despite the changes in policies and family planning programs worldwide, there are large geographic areas that have not yet met the minimum requirements in this regard, the reasons are multiple, including economic reasons but also ideological or religious. Knowledge on the physiology of the menstrual cycle, specifically ovulation process has been further enhanced due to the advances in reproductive medicine research. The series of events around ovulation are used to detect the "fertile window", this way women will look for the possibility of postponing their pregnancy or actually start looking for it. The aim of this article is to review the current methods of family planning based on fertility awareness, from the historical methods like the core temperature determination and rhythm, to the most popular ones like the Billings ovulation method, the Sympto-thermal method and current methods like the two days, and the standard days method. There are also mentioned methods that require electronic devices or specifically computer designed ones to detect this "window of fertility". The spread and popularity of these methods is low and their knowledge among physicians, including gynecologists, is also quite scarce. The effectiveness of these methods has been difficult to quantify due to the lack of well designed, randomized studies which are affected by small populations of patients using these methods. The publications mention high effectiveness with their proper use, but not with typical use, what indicates the need for increased awareness among medical practitioners and trainers, obtaining a better use and understanding of methods and reducing these discrepancies.

Knowledge, attitude and practice of natural family planning methods in a population with poor utilisation of modern contraceptives

Sub-Saharan Africa has one of the highest fertility rates in the world, which is further promoted by the low utilisation of modern contraceptive methods. Yet, many communities claim to have traditional methods of family planning that pre-date the introduction of modern contraceptives, implying that contraception is a culturally acceptable norm. It was therefore postulated that the study population would have a high level of awareness and practice of natural methods of family planning. We aimed to obtain an insight into the extent and correctness of knowledge about natural family planning methods, and its practice as a guide to the general acceptance of contraception as a concept. Pre-tested structured questionnaires were administered to women of childbearing age in households properly numbered for primary healthcare activities. The level of awareness of natural family planning methods was significantly less than awareness for modern methods of contraception. The awareness rate for rhythm method, lactational amenorrhoea method and coitus interruptus was 50.7%, 42.1% and 36.1%, respectively. For all three national family planning methods, there is a steady decline between awareness, correct description of method and utilisation, a difference that was statistically significant in all cases. The sociodemographic factors of the responders had varying influence on utilisation of all three natural family planning methods studied. Rural dwellers practised the lactational amenorrhoea method significantly more often than urban dwellers. Significantly more Muslims than Christians with four children or more practised coitus interruptus or the rhythm method, while the use of lactational amenorrhoea method was significantly increased with the number of living children in both religious groups. There is a relatively low level of awareness of natural family planning methods in the study population, poor utilisation and wrong use of methods. Therefore, improving the correct level of information on natural family planning methods is likely to improve the use of both natural family planning and modern contraceptive methods.

Reasons and correlates of contraceptive discontinuation in Kuwait

OBJECTIVES

(1) To examine the probability of discontinuation of various methods within 1, 2, and three years of use and the reasons for discontinuation; 2) to analyse the socio-demographic correlates of discontinuation.

METHODS

Data from a survey of Kuwaiti women in reproductive ages conducted in 1999 were used. Information on duration of use of modern and traditional methods, and reasons for discontinuation during the 72 months before the survey were analysed. Probabilities of discontinuation were estimated through multiple decrement life table analysis.

RESULTS

After 1 year, 30% of modern and 40% of traditional method users had discontinued; after 3 years, discontinuation increased to 66 and 70%, respectively. After 36 months, only 40% of IUD users discontinued compared with 74% of oral contraceptive users. The desire to become pregnant was the leading reason for discontinuation of most modern methods, while method failure was an equally important reason for traditional methods. Discontinuation was significantly more frequent among higher parity, non-working and Bedouin women, and among those who said Islam disapproves of contraception.

DISCUSSION

Contraception is used largely for spacing. More than two-thirds of the women studied had discontinued most methods after three years, except the IUD, which was used only by about 10% of them. Traditional methods are often discontinued due to method failure and may result in an unintended pregnancy. Better counselling is warranted for traditional methods. Health care for managing side effects of modern methods also needs improvement.

[Contraception--methods of preventing unintended pregnancy. Part II. Medical (artificial) methods of preventing an unintended pregnancy]

Numerous commonly used medical contraception methods have been presented in this article. For obvious reasons, most of them are described only in general. The importance of selecting a method individually for every patient, taking into account her request, efficacy and safety of the method, was particularly emphasized.

Mistiming of intercourse as a primary cause of failure to conceive: results of a survey on use of a home-use fertility monitor

OBJECTIVE

To assess demographics, fecundity characteristics and fertility history of couples who successfully conceived using a home-use Fertility Monitor.

STUDY DESIGN

This was a retrospective US observational study of couples who successfully conceived using a Fertility Monitor. Data were self-reported by volunteers using a questionnaire supplied and collected by mail. Of 276 surveys distributed, 196 (71.0%) were returned and evaluated.

RESULTS

Length of time trying to conceive was < 12 months for 70% of women; proportions were similar across age groupings. After switching to the Fertility Monitor, 49.5% and 91.9% of women had conceived within first and third cycles, respectively. Prior to Fertility Monitor use, conception aids were used by 84.2% and 64.3% had consulted a physician to seek help in attempting to conceive. Average costs of prior treatment were (in US dollars) 6637 dollars; median costs for infertility evaluation were 1075 dollars per cycle. Fertility Monitor costs ranged from 250 dollars for one cycle to 550 dollars after 10 cycles.

CONCLUSIONS

A probable cause for failure to conceive appeared to be mistiming of intercourse. The issue of early intervention with tests and medications were highlighted, resulting in escalating costs and strain on the couple. The use of a home Fertility Monitor that identifies all fertile days of the cycle and allows couples to target intercourse accordingly, should be considered as an alternative choice for couples seeking to conceive during the first year, before other attempts at infertility diagnosis are made, unless there are conflicting clinical reasons.

Fertility awareness-based methods of family planning: predictors of correct use

CONTEXT

Fertility awareness-based methods of family planning help women identify the days of the menstrual cycle when they are most likely to become pregnant. To prevent pregnancy, women avoid unprotected intercourse on these days. Efficacy of these methods may be improved if the users most likely to engage in unprotected intercourse on fertile days can be identified and counseled.

METHODS

Quantitative and qualitative data from efficacy studies of the Standard Days Method and the TwoDay Method of family planning, in which 928 women each contributed up to 13 cycles of method use, were examined. Multinomial logit analysis was used to compare characteristics of women who occasionally had unprotected intercourse on fertile days with those who consistently used their method correctly. The reasons participants gave for having unprotected intercourse on fertile days were also examined.

RESULTS

Only 23% of women had unprotected intercourse on their fertile days in one or more of the cycles they contributed to the study. The method and study site appear to have the most significant effect on correct use. Earning an income was associated with increased odds of unprotected intercourse on fertile days; higher quality of housing was associated with decreased odds. The results confirm the importance of partner cooperation for correct method use.

CONCLUSION

There was no clear profile of clients for whom these family planning methods would be inappropriate. However, programs offering these methods may help couples overcome potential difficulties in correct method use by including male partners and encouraging their participation in counseling sessions.

Contraceptive use by Maori youth in New Zealand: associated risk and protective factors

AIMS

To identify risk and protective factors associated with consistent contraception use by sexually active Maori youth.

METHODS

Secondary analysis was undertaken utilising Youth2000, an anonymous nationally representative secondary school health and wellbeing survey, undertaken in 2001. We describe the self-reported sexual health and contraceptive use behaviours of Maori students. A multiple logistic regression model was utilised to identify risk and protective factors associated with consistent contraception use by sexually active Maori students.

RESULTS

Half of the Maori students have had sexual intercourse (54% males; 48% females) and a third are currently sexually active (33% males; 34% females). Most Maori youth who have ever had sex use condoms for contraception (82%) and most sexually active Maori youth reported consistent use of contraception (71% males; 70% females). Maori youth who use contraception consistently are more likely to report getting enough time with a parent (OR 1.50; 95% CI 1.05-2.14; p=0.03) and less likely to report weekly marijuana use (OR 0.53; 95% CI 0.37-0.76; p=0.0006).

CONCLUSIONS

Consistent use of condoms is a common self-reported contraceptive practice by many young Maori. However this behaviour is not universal, and in view of the significant sexual and reproductive health disparities that exist for Maori youth, sexual and reproductive health programs should examine a broader strategy of promoting protective factors such as strengthening youth-parent relationships and reducing risk factors, such as minimising substance misuse. Together with existing efforts in education, whanau (family), and community based programs, these strategies may support healthier sexual health outcomes for Maori youth.

Use of periodic abstinence in Bangladesh: do they really understand?

Data from a nationally representative study in Bangladesh (BDHS 1996-97) were analysed to identify significant predictors of use of periodic abstinence, in comparison with other modern contraceptive methods. The study found that women in Bangladesh mostly use modern methods during their peak reproductive years, after which some of them switch to periodic abstinence. These women tend to be more from educated and from higher socioeconomic backgrounds and with at least one living son. Another set of data from the Matlab DSS was analysed and the results were in the same direction. Focus group discussions found that women were using the periodic abstinence method incorrectly, abstaining for more days than is necessary. For Bangladeshi contraceptive users to reach a higher degree of use-effectiveness for period abstinence, more IEC materials need to be developed.

Expanding family planning options: offering the Standard Days Method to women in Istanbul

BACKGROUND

This study introduced the Standard Days Method (SDM), a fertility awareness-based method of family planning, to couples in a region of Istanbul, Turkey who were using a method of low effectiveness or no family planning method. The objective was to determine potential demand for, and satisfaction with, the SDM.

METHODS

A total of 657 couples were selected by systematic sampling and offered the SDM. Those accepting this method were interviewed 1 and 3 months after starting the SDM.

RESULTS

Some 47% of the participants were satisfied with the method and intended to continue using it.

CONCLUSIONS

Potential demand for the SDM was 80.3% (278/346 eligible women) among couples who were using a method of low effectiveness or no family planning method. Our results suggest that adding the SDM to the contraceptive method mix may benefit Turkish women.

Determination of the fertile window: reproductive competence of women--European cycle databases

OBJECTIVES

The objective of the present paper is to review the main results of recent European cycle databases on ovulation detection and determination of the fertile window performed by the women themselves.

METHODS

The ongoing German Long-term Cycle Database currently comprises 32788 prospectively collected cycle charts of 1551 women, the I European Cycle Database (10 countries) 1328 women/19048 cycles, the II European Cycle Database (six countries) 782 women/6724 cycles, and the World Health Organization Database (one European country) 234 women/2808 cycles. The women record cycle parameters (cervical mucus changes, temperature rise, etc.), family planning intention and sexual behavior.

RESULTS

With the symptothermal method of natural family planning it has become possible to determine the fertile window in order to avoid pregnancy with a method effectiveness of 0.3%. According to a small sub-study, the ovulation time observed by the women themselves correlates closely with ovulation detected by ultrasound and measurement of luteinizing hormone (correlation within 1 day in 89% of the 62 cycles). Fertility awareness methods can be integrated into the management of sub-fertility. They seem to shorten the time to pregnancy.

CONCLUSIONS

Self-observation of the fertile window puts women into a position to develop a high level of reproductive competence that could be used much more in different areas than is currently the case.

[Causes of non-use of postpartum contraceptive method among adolescent mothers]

OBJECTIVE

To determine the causes of non postpartum contraceptive use among adolescent mothers.

PATIENTS AND METHODS

We conducted a cross-section descriptive study. We included women who asked for attention of an obstetric event in 2002, we identified those were in immediate postpartum period, and we selected those that did not began a birth-control method. Data were collected directly with an interview and revision of the file, later on they were coded and processed manually; the causes of non contraceptive use were classified in: attributable causes to patient: personal, religious, moral, familiar, cultural, etc. Reasons, when they received information and advice or when they did not assist to educational actions; attributable causes to hospital: technique administrative factors, insufficient educational communication activities by service provider; and attributable causes to medical indication: presence of risk factors for health women. The statistical analysis was carried out using frequencies and percentages.

RESULTS

We found 261 women, we identified 160 (61%) in immediate postpartum period, 52 (32%) they did not began contraceptive use.

CONCLUSION

The causes of non postpartum contraceptive use among adolescent mothers were attributable to themselves in 75%, in 21% to the medical unit, and 4% to medical indication.

Natural family planning revisited

The article focuses on the role of natural family planning NFP as a component of reproductive health. It distinguishes NFP from the concept of fertility awareness method. Furthermore, the effectiveness of NFP as determined by previous studies is presented and the advantages and disadvantages of NFP are highlighted. Additionally, factors that influence the use of NFP methods are examined. Finally, delivery strategies and options for mainstreaming NFP into reproductive health services are identified and discussed.

Periodic abstinence in developing countries: an assessment of failure rates and consequences

It is estimated that 27 million couples, representing 2.6% of all couples in the reproductive span, use periodic abstinence (PA). Using data from 15 national surveys in low and middle-income countries, this article assesses characteristics of PA users, knowledge of the fertile period, accidental conceptions while using PA and the reproductive consequences of these conceptions. Current users of PA (predominantly the simple calendar variant) tend to be more educated and urban than users of other methods. The method is preferred by young single women and older married women. The proportion of users with correct knowledge of the timing of ovulation ranges from 8% to 91%, with a median value of 62%. The median 12-month gross failure rate was 24 per 100 episodes. Net of other predictors of failure, correct knowledge of the timing of ovulation was associated with a 12% decrease in failure probabilities. Couples who experienced PA failure were more likely than couples who experienced failure with another method to carry the pregnancy to term. Nevertheless, PA still contributes to one-sixth of all abortions (or miscarriages) following contraceptive failure.

Continued use of contraception among Philippine family planning acceptors: a multivariate analysis

The factors that contribute to continued use of contraception are examined through a multivariate analysis of data gathered in the course of the Philippine 1974 National Acceptor Survey. Twenty-five independent variables were utilized in the analysis, of which only three were found to have an appreciable effect upon continuation: the method accepted, age, and husband's attitude regarding family planning. When the sample was divided into method subgroups, several features of the service process explained variance in pill continuation, and fecundability explained variance in rhythm continuation. The findings suggest that there is considerable potential for improving the effectiveness of the Philippine program through administrative action. Better IUD services and information, more emphasis on the needs of husbands, and improvements in the ongoing support of pill users could substantially improve the amount of contraceptive protection offered by the program.
