Birth controlBirth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent unintended pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable.
Preterm birthPreterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age, as opposed to full-term delivery at approximately 40 weeks. Extreme preterm is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 34 weeks, late preterm birth is between 34 and 36 weeks' gestation. These babies are also known as premature babies or colloquially preemies (American English) or premmies (Australian English).
Birthing centerA birthing center is a healthcare facility, staffed by nurse midwives, midwives and/or obstetricians, for mothers in labor, who may be assisted by doulas and coaches. The midwives monitor the labor, and well-being of the mother and the baby during birth. Doulas can assist the midwives and make the birth easier. Should additional medical assistance be required, the mother can be transferred to a hospital. This transfer is more likely if an epidural is needed, there is meconium staining, it is a prolonged labor, or the newborn needs intensive care.
Birth rateBirth rate, also known as natality, is the total number of live human births per 1,000 population for a given period divided by the length of the period in years. The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population.
Water birthWater birth is labor and sometimes delivery that occurs in water, usually a birthing pool. The American College of Obstetricians and Gynecologists does not recommend birthing in water as the safety has not been determined. Proponents believe childbirth in water results in a more relaxed, less painful experience that promotes a midwife-led model of care. Critics argue that the safety of waterbirth has not been scientifically proven and that a wide range of adverse neonatal outcomes have been documented, including increased mother or child infections and the possibility of infant drowning.
Home birthA home birth is a birth that takes place in a residence rather than in a hospital or a birthing center. They may be attended by a midwife, or lay attendant with experience in managing home births. Home birth was, until the advent of modern medicine, the de facto method of delivery. The term was coined in the middle of the 19th century as births began to take place in hospitals. Multiple studies have been performed concerning the safety of home births for both the child and the mother.
Multiple birthA multiple birth is the culmination of one multiple pregnancy, wherein the mother gives birth to two or more babies. A term most applicable to vertebrate species, multiple births occur in most kinds of mammals, with varying frequencies. Such births are often named according to the number of offspring, as in twins and triplets. In non-humans, the whole group may also be referred to as a litter, and multiple births may be more common than single births. Multiple births in humans are the exception and can be exceptionally rare in the largest mammals.
Childbirth positionsThe term childbirth positions (or maternal birthing positions) refers to the physical postures the pregnant mother may assume during the process of childbirth. They may also be referred to as delivery positions or labor positions. In addition to the lithotomy position (on back with feet pulled up), still commonly used by many obstetricians, other positions are successfully used by midwives and traditional birth-attendants around the world.
Birth defectA birth defect, also known as a congenital disorder, is an abnormal condition that is present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders.
DesignA design is a concept of either an object, a process, or a system that is specific and, in most cases, detailed. Design refers to something that is or has been intentionally created by a thinking agent, though it is sometimes used to refer to the nature of something. The verb to design expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan may also be considered to be a design (such as in some artwork and craftwork).
