Reproductive and Birth Outcomes

 

Low Birth Weight

Birth weight is the weight of the newborn measured immediately after birth. The LDH Tracking Program collects data on low term birth weights, less than 5.5 pounds or 2500 grams, and very low birth weights, less than 3.3 pounds or 1500 grams, among singleton births.

 

Prematurity

The LDH Tracking Program collects information on premature births and very premature births. A baby is considered premature if he or she is born before the 37th completed week of pregnancy, also known as gestation. A baby is considered very premature if he or she is born before the 32nd completed week of pregnancy. Because multiple births, such as twins, triplets, etc., are disproportionately associated with premature births, the measures included here are based only on live singleton births (where only one baby was conceived and born).

 

Mortality

The LDH Tracking Program collects information on infant mortality, neonatal mortality, post-neonatal mortality, and perinatal mortality. Infant mortality occurs when an infant dies before 1 year of age, neonatal mortality occurs when an infant dies before 28 days of age, post-neonatal mortality occurs when an infant dies on or after 28 days of age and before 1 year of age, and perinatal mortality occurs when an infant dies after 28 weeks of gestation and before 7 days of age.

 

Fertility

Fertility refers to the ability to conceive children. According the Centers for Disease Control and Prevention (CDC), about 6% of women in the United States of reproductive age, aged 15-44 years, have difficulty getting pregnant or carrying a pregnancy to term. Infertility may be the result of many different factors including age, existing medical conditions, and possible exposure to environmental contaminants. Total fertility rate (TFR) represent the ratio of live births in an area to the population of women of reproductive age in that area. Total fertility differs from other common fertility measures such as the general fertility rate (GFT) in that it adjusts for age-specific differences in fertility.

 

Male/Female Sex Ratio

The sex ratio is a proportion relating the number of babies born male to number of babies born female. The expected sex ratio at birth is 105 boys born for every 100 girls, which results in male/female sex ratio of 1.05.
