Preterm Birth in Texas
- In 2021, there were 42,518 preterm births in Texas, representing 11.4% of live births.
- In 2021, 1 in 9 babies (11.4% of live births) was born preterm in Texas.
Every baby in Texas deserves the chance to be born healthy.
- In 2018-2021, 107 Texas counties had a preterm birth rate higher than the state rate of 11.0%.
- In 2018-2021, 49 Texas counties had met the Healthy People 2030 preterm rate goal of 9.4%.
Preterm Birth By Race And Ethnicity In Texas
The March of Dimes is concerned about inequities in health and health care that contribute to higher rates of preterm birth among different racial and ethnic groups.
- During 2019-2021 (average) in Texas, preterm birth rates were highest for black infants (14.8%), followed by Hispanics (11.1%), American Indian/Alaska Natives (10.8%), Whites (9.8%) and Asian/Pacific Islanders (9.3%).
- Black infants (14.8%) were about 2 times as likely as Asian/Pacific Islander infants (9.3%) to be born preterm during 2019-2021 (average).
- Of all live births in Texas during 2018-2020 (average), 47.6% were Hispanic, 33.4% were white, 12.9% were black, 0.2% were American Indian/Alaska Native and 5.5% were Asian/Pacific Islander.
Risk Factors for Preterm Birth
Rather than having one cause, preterm birth seems to be triggered by multiple, interacting biologic and environmental factors. We do know that a history of preterm birth, multiple gestations, and certain uterine and/or cervical problems are the strongest risk factors for preterm birth. The factors below also contribute to preterm birth.4
During 2019-2021 (average) in Texas, preterm birth rates were highest for women ages 40 and older (16.8%), followed by women ages 30-39 (11.8%), under age 20 (10.3%) and ages 20-29 (10.3%).
In 2021, 8.5% of women of childbearing age reported smoking in Texas. Smoking is an important determinant of health and a significant factor contributing to preterm births.
In Texas in 2021, 9.7% of singleton births were preterm, compared to of multiple births. Multiple births represent 3.0% of live births in Texas. Current multifetal pregnancy is one of the most consistently identified risk factors for preterm birth.
Birth spacing, or inter-pregnancy interval, is the timing between a live birth and the beginning of the next pregnancy. Birth spacing of less than 18 months increases the risk of preterm birth and other adverse outcomes. In Texas, 30.7% of pregnancies with a prior live birth have a birth spacing of less than 18 months (2018-2020 average).
While obesity does not directly cause preterm birth, it does increase rates of medical complications (e.g., hypertension, diabetes) that contribute to preterm birth. In Texas, 33.8% of women of childbearing age were obese in 2021.
Health Insurance Coverage
In 2021, about 1 in 4 women of childbearing age (24.4%) was uninsured in Texas. Health care before, during and after pregnancy can help identify and manage conditions that contribute to preterm birth.
Other Contributing Factors4
Other factors contributing to preterm birth include: infection (especially genito-urinary), diabetes mellitus, hypertension, late or no prenatal care, alcohol and illicit drug use, and social determinants of health. Socioeconomic status at both the individual and community level (e.g., income/poverty, job status, education) as well as psychosocial factors (e.g., chronic stress, lack of social support) are associated with an increased risk of preterm birth.
Consequences of Preterm Birth
Preterm birth, along with low birth weight babies, make up the second leading cause of infant deaths after birth defects. Health consequences of preterm birth include developmental delays, chronic respiratory problems and vision and hearing impairment1. Having a preterm baby impacts families emotionally and financially.
Infant deaths are preterm-related2
When causes of death related to preterm birth are grouped together, preterm-related causes account for 33.4% of infant deaths in Texas.
Associated with preterm birth
The annual societal economic cost (medical, educational, and lost productivity)3 associated with preterm birth in Texas is an estimated $62,000.

- Smoking is defined as having ever smoked 100 cigarettes in a lifetime and currently smoking everyday or some days. Percent reported is among women ages 18-44.
- Multiple deliveries include twin, triplet and higher order deliveries.
- Birth spacing is the period of time between giving birth and getting pregnant again. Its also called pregnancy spacing or interpregnancy interval (also called IPI).

- A woman was considered uninsured if she was not covered by any type of health insurance at the time of the survey. Percent reported is among women ages 15-44.
- Social determinants of health are the conditions in which people are born, grow, work, live and age, as well as the wider set of forces and systems that shape daily life conditions.
- Prematurity/LBW cause of death is a single cause of death defined as disorders related to short gestation and low birthweight (LBW), not elsewhere classified, determined by Category P07 (four codes) in the tenth International Classification of Diseases (ICD-10).
- Preterm-related cause of death is a grouping of causes of death each determined to be a direct consequence of preterm birth (44 codes from the tenth International Classification of Diseases (ICD-10)).For more information, visit https://www.marchofdimes.org/peristats.
