Induced abortion: incidence and trends worldwide from 1995 to 2008.

BACKGROUND: Data of abortion incidence and trends are needed to monitor progress toward improvement of maternal health and access to family planning. To date, estimates of safe and unsafe abortion worldwide have only been made for 1995 and 2003. METHODS: We used the standard WHO definition of unsafe abortions. Safe abortion estimates were based largely on official statistics and nationally representative surveys. Unsafe abortion estimates were based primarily on information from published studies, hospital records, and surveys of women. We used additional sources and systematic approaches to make corrections and projections as needed where data were misreported, incomplete, or from earlier years. We assessed trends in abortion incidence using rates developed for 1995, 2003, and 2008 with the same methodology. We used linear regression models to explore the association of the legal status of abortion with the abortion rate across subregions of the world in 2008. FINDINGS: The global abortion rate was stable between 2003 and 2008, with rates of 29 and 28 abortions per 1000 women aged 15-44 years, respectively, following a period of decline from 35 abortions per 1000 women in 1995. The average annual percent change in the rate was nearly 2·4% between 1995 and 2003 and 0·3% between 2003 and 2008. Worldwide, 49% of abortions were unsafe in 2008, compared to 44% in 1995. About one in five pregnancies ended in abortion in 2008. The abortion rate was lower in subregions where more women live under liberal abortion laws (p<0·05). INTERPRETATION: The substantial decline in the abortion rate observed earlier has stalled, and the proportion of all abortions that are unsafe has increased. Restrictive abortion laws are not associated with lower abortion rates. Measures to reduce the incidence of unintended pregnancy and unsafe abortion, including investments in family planning services and safe abortion care, are crucial steps toward achieving the Millennium Development Goals.

Unsafe abortion differentials in 2008 by age and developing country region: high burden among young women.

Each year, nearly 22 million women worldwide have an unsafe abortion, almost all of which occur in developing countries. This paper estimates the incidence and rates of unsafe abortion by five-year age groups among women aged 15-44 years in developing country regions in 2008. Forty-one per cent of unsafe abortions in developing regions are among young women aged 15-24 years, 15% among those aged 15-19 years and 26% among those aged 20-24 years. Among the 3.2 million unsafe abortions in young women 15-19 years old, almost 50% are in the Africa region. 22% of all unsafe abortions in Africa compared to 11% of those in Asia (excluding Eastern Asia) and 16% of those in Latin America and the Caribbean are among adolescents aged 15-19 years. The number of adolescent women globally is approaching 300 million. Adolescents suffer the most from the negative consequences of unsafe abortion. Efforts are urgently needed to provide contraceptive information and services to adolescents, who have a high unmet need for family planning, and to women of all ages, with interventions tailored by age group. Efforts to make abortion safe in developing countries are also urgently needed.

Unsafe abortion in 2008: global and regional levels and trends.

Despite the availability of safe and highly effective methods of abortion, unsafe abortions continue to be widespread, nearly all in developing countries. The latest estimates from the World Health Organization put the figure at 21.6 million unsafe abortions worldwide in 2008, up from 19.7 million in 2003, a rise due almost entirely to the increasing number of women of reproductive age globally. No substantial decline was found in the unsafe abortion rate globally or by major region; the unsafe abortion rate of 14 per 1,000 women aged 15-44 years globally remained the same from 2003 to 2008. Modest reductions in unsafe abortion rates were found in 2008 as compared to 2003 in most sub-regions, however. The upward changes in rates in Middle Africa, Western Asia and Central America were due to better coverage and more reliable information in 2008 than in 2003. Eastern and Middle Africa showed the highest rates of unsafe abortion among all sub-regions. Some 47,000 women per year are estimated to lose their lives from the complications of unsafe abortion, almost all of which could have been prevented through better access to sexuality education, fertility awareness, contraception and especially safe abortion services.

Contraceptive use, fertility, and unsafe abortion in developing countries.

OBJECTIVES: Despite a substantial rise in contraceptive use around the world, unplanned pregnancies and induced abortion continue to occur. Each year an estimated 19 million abortions are carried out outside the legal system, often by unskilled practitioners or under unhygienic conditions. This paper explores the relationship between contraceptive prevalence and unsafe abortion in developing regions with different levels of fertility. These relationships manifest the extent to which the desire to regulate fertility is addressed by contraception or by unsafe abortion, where access to safe abortion is legally restricted. METHODS: Secondary analysis of estimates of unsafe abortion, total fertility rate and contraceptive prevalence, by geographical regions. RESULTS: High levels of unsafe abortion persist even where contraceptive prevalence is increasing and fertility is declining. It appears that a high dependence on sterilization for limiting family size may by be preceded by reliance on unsafe abortion, where abortion is restricted, for birth spacing. CONCLUSIONS: The reliance on unsafe abortion could be reduced during fertility transition by improving women's access to reversible contraceptives for spacing births as well as to sterilization for terminating childbearing. Expanding contraceptive choices and a balanced method mix can serve as an effective strategy to prevent unsafe abortion where reliance on sterilization to limit childbearing is not preceded by the use of reversible modern methods for spacing and where access to safe abortion is restricted by law. The intriguing association between contraceptive method choice and the incidence of unsafe abortion deserves further exploration.

Unsafe abortion: global and regional incidence, trends, consequences, and challenges.

OBJECTIVE: This review aims to provide the latest global and regional estimates of the incidence and trends in induced abortion, both safe and unsafe. A related objective is to document maternal mortality due to unsafe abortion. The legal context of abortion and the international discourse on preventing unsafe abortion are reviewed to highlight policy implications and challenges in preventing unsafe abortion. METHODS AND DATA SOURCES: This review is based on estimates of unsafe abortion and maternal mortality ratios. These estimates are arrived at using the database on unsafe abortion maintained by the World Health Organization. Additional data from the Demographic and Health Surveys and the United Nations Population Division are used for further analysis of abortion and mortality estimates. RESULTS: Each year 42 million abortions are estimated to take place, 22 million safely and 20 million unsafely. Unsafe abortion accounts for 70,000 maternal deaths each year and causes a further 5 million women to suffer temporary or permanent disability. Maternal mortality ratios (number of maternal deaths per 100,000 live births) due to complications of unsafe abortion are higher in regions with restricted abortion laws than in regions with no or few restrictions on access to safe and legal abortion. CONCLUSION: Legal restrictions on safe abortion do not reduce the incidence of abortion. A woman's likelihood to have an abortion is about the same whether she lives in a region where abortion is available on request or where it is highly restricted. While legal and safe abortions have declined recently, unsafe abortions show no decline in numbers and rates despite their being entirely preventable. Providing information and services for modern contraception is the primary prevention strategy to eliminate unplanned pregnancy. Providing safe abortion will prevent unsafe abortion. In all cases, women should have access to post-abortion care, including services for family planning. The Millennium Development Goal to improve maternal health is unlikely to be achieved without addressing unsafe abortion and associated mortality and morbidity.

Induced abortion: estimated rates and trends worldwide.

BACKGROUND: Information on incidence of induced abortion is crucial for identifying policy and programmatic needs aimed at reducing unintended pregnancy. Because unsafe abortion is a cause of maternal morbidity and mortality, measures of its incidence are also important for monitoring progress towards Millennium Development Goal 5. We present new worldwide estimates of abortion rates and trends and discuss their implications for policies and programmes to reduce unintended pregnancy and unsafe abortion and to increase access to safe abortion. METHODS: The worldwide and regional incidences of safe abortions in 2003 were calculated by use of reports from official national reporting systems, nationally representative surveys, and published studies. Unsafe abortion rates in 2003 were estimated from hospital data, surveys, and other published studies. Demographic techniques were applied to estimate numbers of abortions and to calculate rates and ratios for 2003. UN estimates of female populations and livebirths were the source for denominators for rates and ratios, respectively. Regions are defined according to UN classifications. Trends in abortion rates and incidences between 1995 and 2003 are presented. FINDINGS: An estimated 42 million abortions were induced in 2003, compared with 46 million in 1995. The induced abortion rate in 2003 was 29 per 1000 women aged 15-44 years, down from 35 in 1995. Abortion rates were lowest in western Europe (12 per 1000 women). Rates were 17 per 1000 women in northern Europe, 18 per 1000 women in southern Europe, and 21 per 1000 women in northern America (USA and Canada). In 2003, 48% of all abortions worldwide were unsafe, and more than 97% of all unsafe abortions were in developing countries. There were 31 abortions for every 100 livebirths worldwide in 2003, and this ratio was highest in eastern Europe (105 for every 100 livebirths). INTERPRETATION: Overall abortion rates are similar in the developing and developed world, but unsafe abortion is concentrated in developing countries. Ensuring that the need for contraception is met and that all abortions are safe will reduce maternal mortality substantially and protect maternal health.

Access to safe abortion: progress and challenges since the 1994 International Conference on Population and Development (ICPD).

BACKGROUND: The 1994 International Conference on Population and Development (ICPD) viewed access to safe abortion as imperative for public health. PROGRESS SINCE ICPD: Globally, the number of induced abortions (safe and unsafe) per 1000 women aged 15-44 years declined from 35 in 1995 to 28 in 2008. The number of deaths due to unsafe abortion declined from 69,000 in 1990 to 47,000 in 2008, as safe and effective methods of abortion, including manual vacuum aspiration and medical abortion, became more widely available. During the same period, there was a slight increase in the number of countries where abortion is permitted on request, and 70 countries made grounds for abortion more liberal. CHALLENGES: Since ICPD, the decline in unsafe abortion was slower than that in safe abortion, and unsafe-abortion-related mortality continued to be a problem. Nearly all unsafe abortions and mortality occur in developing countries. RECOMMENDATIONS: While more must be done to ensure universal access to safe, acceptable and affordable contraception to reduce the need for abortion, this need will always exist. Information on grounds for safe abortion should be made widely available for women to access services to which they are legally entitled to. As recommended by ICPD, quality postabortion care including contraception counseling and provision should be available to all women, regardless of the legal grounds for abortion. The paper provides the evidence on unsafe abortion, a reproductive health issue that is entirely preventable but has been largely neglected or tarnished by emotional and contentious debates.

New estimates and trends regarding unsafe abortion mortality.

BACKGROUND: The 1990-2008 estimates for the maternal mortality associated with unsafe abortion require a re-examination. OBJECTIVE: To provide the latest estimates of the mortality associated with unsafe abortion and to examine trends within the framework of new maternal mortality estimates. SEARCH STRATEGY: Extensive search of databases and websites for country- and region-specific data on unsafe abortion. SELECTION CRITERIA: Reports, papers, and websites with data on unsafe abortion incidence and mortality. DATA COLLECTION AND ANALYSIS: Earlier published estimates for the unsafe-abortion-related mortality were recalculated by country for 1990, 1997, 2000, and 2003 to harmonize with the new maternal mortality estimates. The resulting estimates were aggregated to give subregional, regional, and global figures, including those recently estimated for 2008. MAIN RESULTS: In 2008, unsafe abortions accounted for an estimated 47000 maternal deaths, down from 69000 in 1990. Globally, the unsafe-abortion mortality ratio has declined from 50 in 1990 to 30 in 2008. The overall burden of unsafe abortion mortality continues to be the highest in Africa. CONCLUSIONS: Important gains have been made in reducing maternal deaths attributable to unsafe abortion. However, 1 in 8 maternal deaths globally and 1 in 5 maternal deaths in Eastern Africa continue to be attributable to unsafe abortion. Averting these preventable deaths can contribute to achieving Millennium Development Goal number 5 of improving maternal health.

Unsafe abortion: worldwide estimates for 2000.

Unsafe abortion is preventable and yet remains a significant cause of maternal morbidity and mortality in much of the developing world. Over the last decade, the World Health Organization has developed a systematic approach to estimate the regional and global incidence of unsafe abortion. Estimates based on figures around the year 2000 indicate that 19 million unsafe abortions take place each year, that is, approximately one in ten pregnancies ended in an unsafe abortion, giving a ratio of one unsafe abortion to about seven live births. Almost all unsafe abortions take place in the developing world. In Latin America and the Caribbean, 3.7 million unsafe abortions are estimated to take place each year, with an abortion rate of 26 per 1000 women of reproductive age, almost one unsafe abortion to every three live births. Asia has the lowest unsafe abortion rate at 11 per 1000 women of reproductive age, but 10.5 million unsafe abortions take place there each year, almost one unsafe abortion to every seven live births. However, excluding East Asia, where most abortions are safe and accessible, the ratio for the rest of Asia is one unsafe abortion to five live births. In Africa, 4.2 million abortions are estimated to take place per year, with an unsafe abortion rate of 22 per 1000 women, or one unsafe abortion per seven live births. In contrast, there is one unsafe abortion per 25 live births in developed countries.

Age patterns of unsafe abortion in developing country regions.

Globally, 19 million women are estimated to undergo unsafe abortions each year. Age patterns of unsafe abortion are critical for tailoring effective interventions to prevent unsafe abortion and for providing post-abortion care. This paper estimates the incidence and the rate of unsafe abortion among women aged 15-44 in the Africa, Asia (excluding Eastern Asia), and Latin America/Caribbean regions, where a woman is likely to have close to one unsafe abortion by age 44. For developing regions as a whole, two-thirds of unsafe abortions occur among women aged 15-30 and 14% among women under age 20. The age pattern of unsafe abortions differs markedly between regions, however. Almost 60% of unsafe abortions in Africa are among women under age 25 and almost 80% are among women under 30. In Asia 30% of unsafe abortions are in women under 25 and 60% in women under 30. In Latin America and the Caribbean, women aged 20-29 account for more than half of unsafe abortions with almost 70% in women under 30. Over 40% of unsafe abortions among adolescents in the developing world occur in Africa, where one in four unsafe abortions takes place during adolescence. Young (under age 25) women in Africa, those over age 25 in Asia and women aged 20-35 years in Latin America and the Caribbean are in the greatest need of interventions to prevent unsafe abortion and good quality post-abortion care.
