The 2012 Indiana Natality Report includes information on
live births to Indiana
residents that occurred during calendar year 2012. Information is presented at the state, county, and city level (for the 35 Indiana cities with populations over 25,000
in the 2010 census). This
report includes data by age, race, and marital status of the parents; characteristics of the newborn, e.g., birth order and
age of mother; and outcome indicators, e.g., tobacco use during pregnancy, gestation length, and birthweight.
Starting in 2012 we are reporting on the number of births to
mothers on Medicaid. Alcohol use is no longer reported on the new birth
certificate, which went into effect in 2007. The data were provided in
Tables 22, 23, and 32. The Medicaid data will be provided in those tables now.
A map of Medicaid births that are significantly different from the State
percentage can be found in Figure 33.
The 2012 Indiana Natality Report also includes information on the number of reported pregnancies by county of residence
and age of mother. Reported pregnancies include resident live births, fetal deaths, and terminated pregnancies (performed in Indiana). Rates
per 1,000 females in selected age groups are also provided.
In this report, we suppressed the number
and percent/rate of births and pregnancies at the county and city subgroup level
when there were fewer than 5, including 0, events. This is done to protect the confidentiality of individuals.
Rates or percents based on less than 20 in the numerator are considered
unstable, and should be interpreted with caution. These rates or percents are marked with a "U".
The Indiana State Department of Health (ISDH), through provisions in
Indiana Code 16-37-1, administers "...a system of vital
statistics for Indiana." The ISDH Vital Records Division compiles data from original birth certificates filed with the
ISDH and from transcripts of original certificates for Indiana residents giving birth in other states. The Data Analysis Team
in the Epidemiology Resource Center in the Public Health Protection and
Laboratory Services Commission compiles these data and produces standard statistical reports.
Indiana began using the 2003 US Standard Certificate of Live
Birth (the 2003 "revised" certificate) on January 1, 2007.
Although much of the information collected from the mother remained the same, some
questions were rephrased or the information was gathered in a different manner.
This resulted in significant changes in some variables.
The major variables affected were month prenatal care began, smoking during pregnancy,
place of birth, and alcohol use during pregnancy.
Mother's alcohol use is no longer collected. The 2007 - 2012 data on prenatal care, tobacco use,
place of delivery,
primary cesarean delivery and vaginal birth after previous cesarean delivery are
not considered comparable to data prior to 2007 due to the significant changes
in wording on the
certificates. These changes are detailed below:
Prenatal Care: The month prenatal care began has been changed
from a box asking for the month of pregnancy in which prenatal care began to
questions asking for the date of last normal menses and the date of the first
prenatal visit. The month prenatal care began is then calculated from
these two variables. If the day of the month was unknown, the day of the
month was imputed using a program that the National Center for Health Statistics (NCHS) has developed. NCHS has
observed a decrease in the
percent of mothers receiving care in the first month for all states who have
adopted the revised certificate and considers it to be the
result of better reporting.
Tobacco Use: Prior to 2007, the question was asked "Did mother smoke during pregnancy?"
Depending on the response, the facility would check one of the following boxes: Yes, No, or Unknown. Starting in 2007,
more detailed information
was collected -- the average number of cigarettes (or packs of cigarettes) that were smoked during
the three months prior to becoming pregnant, the first three months of pregnancy, the second three months
of pregnancy, and the last trimester of pregnancy. If the mother smoked at any time
during her pregnancy,
she was considered to be a smoker for this report.
Primary cesarean and vaginal birth after previous cesarean (VBAC):
Prior to 2007,
there were check boxes
for the method of delivery, which included VBAC. The certificate now contains check boxes for
vaginal/spontaneous, vaginal/forceps, vaginal/vacuum, and cesarean delivery. Under cesarean, the question is
asked "Was a trial of labor attempted?" with check boxes for Yes and No. To determine if the method
of delivery was a primary cesarean, repeat cesarean, or VBAC, a new
risk factor was checked: "Mother had a previous cesarean delivery." If the box was
checked, the number of previous cesareans was reviewed.
Weight Gain: Prior to 2007, weight gain during pregnancy was asked
directly. Starting in 2007, two new questions were asked instead --the
mother's pre-pregnancy weight and the mother's weight at delivery. Weight gain
was then calculated based
on those two responses.
Place of birth: The place of birth information has
been expanded and classified into slightly different categories. In
home births are now sub-divided into intended and unintended
of mother and father: Indiana now uses the 1997 Office of Management
and Budget (OMB) standards for collecting data on race and ethnicity.
Starting with the 2007 birth certificate, mother and father can
check more than one box for race. All racial and ethnicity information is now sent to the National
Center for Health Statistics (NCHS) which imputes a single ("bridged") race to the mother and
father based on the combination of races, Hispanic origin, sex, and age. This
"bridged" race is what is used in this report.
relationship between the two OMB standards and the terms used to
report race and ethnicity in this report are as follows:
