Abstract
Teen pregnancy in the United States is higher when the nativity of the mother
is inside the US
Background:
As the latest vital statistics have shown that teen pregnancy is dropping in the US
while there are sporadic studies implicating that teen pregnancy in the US is less
likely when the nativity of the mother is outside the 50 states of the US.
Purpose:
To test the hypothesis that teen pregnancy is lower in the mothers whose nativity is
outside the 50 states of the US.
Methods:
VSS data from the NCHS was analyzed for the years 1995 thru 2002. Logistic
regression analysis was performed with the dependent variable teen pregnancy, TP,
with maternal place of birth, MPB as independent variable. The confounding
variables were maternal race, gestational age, GA, birth weight, BWT, maternal
conditions such as diabetes, hypertension, pregnancy induced hypertension,
maternal exposure to alcohol and tobacco. Also considered variables were prenatal
care , plurality, and gender. Stata 12.0 was utilized for statistical analysis.
Results:
Out of over 31 million records for births during the period 1995 thru 2002 over 25
million births had usable data. Over all, births to teen mothers were significantly
more likely if their nativity was within the 50 states of the US , OR 2.49 cf (95%)
2.48-2.50 while controlling for other confounders. Every ethnicity and race was
affected by the maternal nativity.
Conclusion:
We accept the hypothesis that teen pregnancy is lower when the maternal nativity is
outside the US.
Reason for higher teen pregnancy rates when mother’s nativity is from the US is
concerning and needs to be decreased.
Objectives
Teenage motherhood is burdensome both at a personal and
community level in any population. Recently a report from
CDC, Birth Rates for U.S. Teenagers Reach Historic Lows
for All Age and Ethnic Groups, indicated a success in our
efforts. However an area of interest , along the lines of whether
the nativity of the mother mattered. Various articles with
respect to nativity of the pregnant mothers implied that
mothers with nativity in the US tend to have poorer outcomes
than those with nativity elsewhere.
Why ? United States is the most resourceful country in the
world.
We wanted the see the trend in pregnancies to the teenage
mothers who delivered in the US with respect to their nativity.
Purpose:
To test the hypothesis that teen pregnancy is lower in the
mothers whose nativity is outside the 50 states of the US.

VSS data from the NCHS were used in the analysis.
Years studied: 1995 to 2002
Variables used: Maternal Age

Race
Gestational age
Birth weight
Maternal condition during pregnancy
(Diabetes, hypertension, pregnancy
induced

Logistical regression was performed with the dependent
variable
birth to teen age mother, TP, with maternal place of birth as
the
independent variable, while rest of variable were tested for
confounding.
Analysis and plots were done using Stata 12.0 and Excel

1. We accept the hypothesis that teen
pregnancy is lower when the
maternal nativity is outside the US.
2. Reason for higher teen pregnancy
rates when mother’s nativity is from
the US is concerning and needs to
be decreased.
