CHAPTER 2
VITAL HEALTH INDICATORS
MATERNAL VITAL STATISTICS
Understanding how a population is coping with the burdens of reproduction is vital. High-quality population based data are essential in the interpretation of obstetric and maternal care. This valuable insight can provide populations with the opportunity to intervene for improved outcomes for women and infants.
MATERNAL MORTALITY RATIO (MMR)
MATERNAL DEATH
Maternal death is ‘death of a woman while pregnant or within 42 days (6 weeks) of termination of pregnancy, irrespective of the duration or site of pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental cause.
No. of maternal deaths in a given year
Total no. of live births in the same year× 100,000
MMR=
MATERNAL MORTALITY RATE
It can be obtained by dividing the average annual number of maternal deaths in a population by the average number of women of reproductive age (15- 49 years of age) who are alive during the observation period.
CLASSIFICATION
The causes of maternal death may be classified into
MENTAL ILLNESS
When an individual is not able to view himself/ herself clearly or has a distorted view about self, is unable to maintain satisfying personal relationships with others, and is unable to adapt his/her environment, a mental illness occurs.
FACTORS ASSOCIATED WITH MATERNAL MORTALITY
Five Clearly Defined Global and National Targets for 2025
The Ending Preventable Maternal Mortality (EPMM) initiative, which includes a broad coalition of partners working in maternal and newborn health, has established new coverage targets and milestones that need to be achieved by 2025 if the SDGs are to be met.

STEPS TO REDUCE MATERNAL MORTALITY
INFANT MORTALITY RATE
It is the number of deaths under one year of age per 1000 live births in one year.
Infant mortality rate is the ratio of infant deaths registered in a given year to the total number of live births registered in the same year.
Number of deaths under one year of age
Total live births in the year
IMR =
× 1000
THE CAUSES OF INFANT MORTALITY ARE AS FOLLOW:
Biological factors:
Birth weight (BW)
Age of mother
Birth order :
Birth spacing
Multiple births
High fertility
Economic factors
Socio-economic status (SES)
Cultural and social factors:
Breastfeeding
Religion and caste
Early marriages
MEASURES TAKEN TO REDUCE INFANT MORTALITY RATE
NEONATAL MORTALITY RATE (NNMR)
× 1000
No. of neonatal deaths in a given year
Total no. of live births in the same year
EARLY NEONATAL MORTALITY
LATE NEONATAL MORTALITY (LNNM)
CAUSES OF NEONATAL MORTALITY (0-4 WEEKS)
MEASURE TO REDUCE IMR
PERINATAL MORTALITY RATE
Perinatal mortality is defined as deaths among fetuses weighing over 1000 gm at birth who die before and during delivery or within the first 7 days of delivery. The perinatal mortality rate is expressed in terms of such deaths per 1000 total births.
Perinatal mortality rate =
Number of deaths occurring from 28 weeks of Gestation or under one week after birth
Total no. of live births in the same year
× 1000
Predisposing Factors of Perinatal Mortality
Causes of Perinatal Mortality
Prevention of Perinatal Mortality
FERTILITY RATES
The general fertility rate is the number of resident live births for a specified geographic area (nation, state, county, etc.) during a specified period (usually a calendar year) divided by the female population aged 15-44/49 years (usually estimated for a mid-year) for that area, and the resulting fraction multiplied by 1,000.
GFR =
Number of live births in an area during the year
Total Female population aged 15-44/49 in the same area in the same year
× 1000
OTHER IMPORTANT HEALTH INDICATORS
Under-Five Mortality Rate
It is the annual number of deaths of children aged under 5 years, expressed as a rate per 1000 live births.
Under-five mortality rate =
Number of deaths of children less than 5 years of age in a year
Number of live births in the same year
× 1000
Birth Rate
The Birth rate is defined as the number of live births during a year per 1000 estimated mid-year population. It is given by the formula:
Number of live births during the year
Estimated midyear population
× 1000
Birth rate =
Death Rate
The death rate is defined as the number of deaths per 1000 population estimated mid-year population in one year. It is given by the formula:
Death rate =
× 1000
Number of deaths during the year
Estimated midyear population
STILL BIRTH
A stillbirth is a birth of a newborn after the 28th completed week when the baby does not breathe or show any sign of life after delivery. Such deaths include antepartum deaths and intrapartum deaths. The stillbirth rate is the number of such deaths per 1000 births.
Antepartum deaths �Intrapartum deaths �Acute fetal distress �Traumatic vaginal delivery leading to asphyxia or intracranial hemorrhage. �Asphyxia-premature babies are more vulnerable. �Congenital malformation of the fetus.
