birth

 [berth]
a coming into being; the act or process of being born.
birth certificate a written, authenticated record of the birth of a child, required by state laws throughout the United States. After a birth is registered, a birth certificate is issued which represents legal proof of parentage, age, and citizenship, and is of great personal and legal importance. A birth certificate is required for many legal and business or personal transactions. Whether the child is born at home or at the hospital, the physician, midwife, or other attendant must report the birth to the local or state registrar. The report becomes a permanent record, and a certificate is issued to the parents. If a child dies during birth, an immediate report and certification of the birth and death are required, containing a statement of the cause of death.
birth control the concept of limiting the size of families by measures designed to prevent conception. The movement of that name began in modern times as a humanitarian reform to conserve the health of mothers and the welfare of children, especially among the poor. More recently it has been superseded by the term family planning, which means planning the arrival of children to correspond with the desire and resources of the married couple. See also contraception.
multiple birth the birth of two or more offspring produced in the same gestation period.
premature birth (preterm birth) expulsion of the fetus from the uterus before termination of the normal gestation period, but after independent existence has become possible; defined as birth occurring before 37 completed weeks (295 days), counting from the first day of the last normal menstrual period. Approximately 6 to 8 per cent of all live births in the United States are premature, and premature births are the major cause of neonatal morbidity and mortality.

birth interval

multiple birth

birth order
the chronological order of births in a multiple birth. May have significance in causing stillbirths if the intervals between births are prolonged because of inertia.
premature birth
expulsion of the fetus from the uterus before termination of the normal gestation period, but after independent existence has become a possibility. In humans prematurity is defined as a pregnancy of less than 37 weeks in a pregnancy normally lasting 40 weeks.
birth process
comprises maturation of the fetus, relaxation of the bony pelvis and associated ligaments, softening and relaxation of the cervix, vagina, vulva and perineum, correct disposition of the fetus, contractions of the uterine myometrium and finally the only component under voluntary control, contraction of the abdominal muscles.
birth rate
the number of births during one year for the total population (crude birth rate), for the female population (refined birth rate), or for the female population of reproductive age (true birth rate). Not a term much used with reference to animals. See calving, lambing rate.
birth size
stature, including height at withers, crown to tail head length at birth.
birth weight
the weight at birth. A significant determinant of survival in any species and of the occurrence of dystocia. See also prolonged gestation.
