Long-Acting and Permanent Contraception: An International Development, Service Delivery Perspective Roy Jacobstein, MPH, MD Recent scientific findings about long-acting and permanent methods of contraception underscore their safety, effectiveness, and wide eligibility for individuals who desire them. This has led to new guidance from the World Health Organization to inform national policies, guidelines, and standards for service delivery. Although developing countries have made much progress in expanding the availability and use of family planning services, the need for effective contraception in general (and long-acting and permanent methods in particular) is large and growing because the largest cohorts in human history are entering their reproductive years. More than half a billion people will use contraception in developing countries (excluding China) by 2015, an increase of 200 million over levels of use in 2000. The health, development, and equity rationales that historically have underpinned and energized the international family planning effort remain valid and relevant today. Despite the other compelling challenges faced by the international health community, the need to make family planning services more widely available is pressing and should remain a priority.

An even greater challenge will be to meet the Agency for International Development (USAID) for contraceptive needs of the largest cohorts in human family planning in general and for long-acting and history to enter their reproductive years. There will be permanent methods of contraception in particular. The more than half a billion contraceptive users in developing methods considered “long-acting” in this context are countries (excluding China) by 2015, an increase of 200 intrauterine devices (IUDs) and implants; vasectomy and million people over the number of people using contra- female sterilization are considered “permanent.” In- ception in 2000.

Related to these levels of contraceptive use, maternal WHO’s guidance documents are available to inform mortality is a great rarity in the developed world (e.g., national policies, guidelines, and standards for delivery two deaths per 100,000 live births in Sweden), whereas of family planning services, which in turn should help in the developing world, maternal morbidity and mortal- foster wider access to family planning services.
