Almost half of all pregnancies in Hawaii in 2011 were unintended. Unintended pregnancy is associated with an increased risk of morbidity for women, and with health behaviors during pregnancy that are associated with adverse effects. For example, women with an unintended pregnancy may delay prenatal care, which may affect the health of the infant. Having the ability to plan for a pregnancy can contribute to improved health outcomes for the mother, the infant, and the family. Although an unintended pregnancy can happen at any reproductive age, some groups are at a higher risk. Over 3/4 of pregnancies among teens were unintended in Hawaii in 2011. Efforts to decrease unintended pregnancy include finding better forms of contraception, and increasing contraceptive use and adherence.
