'''Mortinatality''' (/môr′tinātal′itē/), also known as '''natimortality''', is a demographic and medical term for the '''stillbirth rate'''. It measures the frequency of fetal deaths occurring late in pregnancy relative to the total number of births. The term is a blend of the Latin words ''mors'' ("death") and ''natus'' ("birth"), literally meaning "death at birth."

As a key indicator in public health, the mortinatality rate provides critical insights into the quality of maternal and child healthcare, particularly antenatal (prenatal) and intrapartum (during delivery) care.

== Definition and Terminology ==
While mortinatality refers to the rate, the event it measures is a '''stillbirth'''. A stillbirth is the death of a fetus in the uterus at a stage of development when it would typically be expected to survive.

The exact gestational age used to define a stillbirth can vary between countries and organizations, but it is generally defined as fetal death occurring at or after '''20 to 28 weeks of gestation'''. Fetal loss before this threshold is typically classified as a miscarriage or spontaneous abortion.

It is important to distinguish mortinatality from related measures:

* '''Neonatal Mortality:''' The death of a live-born infant within the first 28 days of life.
* '''Perinatal Mortality:''' A broader measure that combines stillbirths (fetal deaths) and early neonatal deaths (typically deaths of live-born infants within the first week of life). Mortinatality is, therefore, a component of the overall perinatal mortality rate.

== Calculation ==
The mortinatality or stillbirth rate is calculated using a standard formula to allow for comparison across different populations and time periods.

Mortinatality Rate=Total Number of Births (Live Births + Stillbirths) in that YearNumber of Stillbirths in a Year×1000

The rate is expressed as the number of stillbirths per 1,000 total births.

== Causes and Risk Factors ==
The causes of stillbirth are complex and varied, and in a significant number of cases, a specific cause cannot be identified. The most common known causes and risk factors include:

* '''Placental Problems:''' Issues such as placental abruption (where the placenta separates from the uterine wall) and general placental insufficiency are among the most common causes. These conditions disrupt the supply of oxygen and nutrients to the fetus.
* '''Birth Defects and Genetic Abnormalities:''' Chromosomal disorders or structural defects in the fetus can be incompatible with life.
* '''Maternal Health Conditions:''' Chronic health issues in the mother, such as hypertension (high blood pressure), pre-eclampsia, and diabetes, significantly increase the risk.
* '''Infections:''' Infections in the mother, placenta, or fetus can lead to stillbirth. Common culprits include bacterial infections, malaria, syphilis, and listeriosis.
* '''Umbilical Cord Accidents:''' Complications like the cord becoming knotted or wrapped tightly around the fetus can cut off its oxygen supply.
* '''Socioeconomic Factors:''' The stillbirth rate is highest in low-resource settings. Lack of access to quality healthcare, poor nutrition, and poverty are major contributing factors.
* '''Maternal Age and Lifestyle:''' Risk is higher for mothers younger than 20 or older than 35. Lifestyle factors such as smoking, obesity, and substance use during pregnancy also increase the risk.

== Public Health and Prevention ==
Tracking mortinatality is essential for evaluating the effectiveness of a healthcare system. A high rate often points to deficiencies in prenatal care, disease screening, and skilled attendance at birth.

Globally, there are significant disparities, with the vast majority of stillbirths occurring in low- and middle-income countries, particularly in sub-Saharan Africa and South Asia. Many of these deaths are preventable with improved healthcare.

Strategies for reducing the mortinatality rate include:

* Ensuring universal access to high-quality prenatal care.
* Screening for and managing maternal health conditions like hypertension and diabetes.
* Providing skilled care during childbirth.
* Educating expectant mothers on important signs, such as monitoring fetal movements in the third trimester.
* Promoting healthy lifestyles before and during pregnancy.
