Contraception and health

摘要: Summary Increasing contraceptive use in developing countries has cut the number of maternal deaths by 40% over past 20 years, merely reducing unintended pregnancies. By preventing high-risk pregnancies, especially women high parities, and those that would have ended unsafe abortion, increased reduced mortality ratio—the risk death per 100 000 livebirths—by about 26% little more than a decade. A further 30% could be avoided fulfilment unmet need for contraception. The benefits modern contraceptives to women's health, including non-contraceptive specific methods, outweigh risks. Contraception can also improve perinatal outcomes child survival, mainly lengthening interpregnancy intervals. In countries, prematurity low birthweight doubles when conception occurs within 6 months previous birth, children born 2 years an elder sibling are 60% likely die infancy after their sibling.
