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. FUNDING: Wellcome Trust, Pan American Health Organization.

[Family planning methods based on fertility awareness]. / Métodos de planificación familiar basados en el conocimiento de la fertilidad.

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.

Adding the Standard Days Method® to the contraceptive method mix in a high-prevalence setting in Peru.

OBJECTIVE: To determine what contribution the Standard Days Method® (SDM) makes to the contraceptive mix offered by regular health services in areas of Peru where contraceptive prevalence rates (CPR) are already high. METHODS: SDM was added to the family planning methods offered by the Ministry of Health in two provinces in Peru in September 2002. Retrospective interviews were conducted in March-June 2004 with 1 200 women who had chosen SDM as their contraceptive method and had used it for 2-20 months. Data were also obtained from the databases of the participating health services. The evaluation covered SDM demand, whether or not clients were switching to SDM from other modern methods, and SDM continuation and effectiveness. RESULTS: Demand for SDM stabilized at 6% of all new family planning users. Most users had not been using any reliable contraception at the time they started using SDM. About 89% of those who began using SDM at least 6 months before the interview were still using it at 6 months. The 12-month typical use pregnancy rate was estimated to be around 10.0 per 100 women years. CONCLUSIONS: Adding SDM to a program's existing contraceptive method mix can increase coverage even in an already high-CPR setting. Most women who choose SDM do not switch from any other modern family planning method. Continuation compares well with other modern user-directed methods. SDM effectiveness, when offered in regular service delivery circumstances, compares well to efficacy trial findings.

Wanted and unwanted fertility in Bolivia: does ethnicity matter?

CONTEXT: In Bolivia, the total fertility rate (TFR) among indigenous populations is higher than that among the nonindigenous population. It is important to investigate whether this difference is attributable to ethnic differences in wanted or unwanted fertility. METHODS: Data from the 2003 Bolivian Demographic and Health Survey were used to estimate women's wanted and unwanted TFRs. Logistic regression analyses were conducted to examine whether women's, men's and couples' characteristics were associated with use of any contraceptive method and modern methods. RESULTS: The TFRs for indigenous and nonindigenous women were 1.5 and 1.7, [corrected] respectively. The wanted fertility rate for indigenous women was nearly the same as that for nonindigenous women (2.8 and 1.4, [corrected] respectively); virtually all of the ethnic difference in the TFRs was attributable to the ethnic difference in unwanted fertility. The proportion of women in need of contraception was greater among indigenous women than among nonindigenous women (26% vs. 19%). In logistic regression analyses, male fertility preferences explained only a small part of the ethnic difference in contraceptive use. CONCLUSION: Women's, men's and couples' preferences contribute only marginally to unwanted fertility, suggesting that structural factors act as obstacles to preventing unwanted fertility.

[Causes of non-use of postpartum contraceptive method among adolescent mothers]. / Causas de no uso de método anticonceptivo posparto entre madres adolescentes.

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.
