East Metro Birth Outcomes
This report responds to concerns in east metro communities around legacy perfluorochemicals (PFCs) contamination and adverse birth outcomes. MDH examined vital records data for two key indicators: low birth weight and prematurity. We looked at community-level trends to identify areas with unusually high rates of these indicators. Specifically we looked at whether these trends show differences related to social and economic factors that are important in identifying communities where people don’t have what they need to be healthy.
- There is a lot of variation but the small differences are not outside of what we would expect given what we know about the east metro and the rest of the state.
- Variation across areas and differences over time do not suggest any unusual increase in low birth weight or premature births in Washington County.
- Health inequities across the diverse county population are consistent with differences and trends we see across Minnesota. Addressing these inequities is a central piece of the department of health’s work and priorities.
While these findings are instructive, the department only examined data for two potential health outcomes: birth outcomes and cancer. MDH has not collected public health data on other types of potential health effects reported in the scientific literature, such as liver and kidney effects, thyroid disease, or immune system changes. While MDH’s water guidance values protect against all of these effects, data on their occurrence in people are not available.
Adverse birth outcomes can have life-long health risks
Being born too soon (premature) or too small (low birth weight) can lead to serious life-long health risks. Premature and low birth weight babies are vulnerable to sickness and infection and have higher risks for infant mortality. Roughly 7% of babies in Minnesota are born premature before reaching “full-term” at 37 completed weeks of pregnancy (not counting multiple births, like twins). That’s over 5,000 babies a year born premature in Minnesota. Roughly 2% of single full-term births in Minnesota are born with low weight.
Most recent statewide data show that teens and women over age 40 are more likely to have a low birth weight or premature birth. Non-white mothers – including Hispanic, African American, American Indian, Asian and Pacific Islander mothers – are also more likely than white mothers to have adverse birth outcomes.
Steps to take for a healthy pregnancy and healthy baby
Women who are pregnant or may become pregnant can reduce the likelihood of an adverse birth outcome with the following guidelines:
- Stop smoking and avoid exposure to secondhand smoke
- Do not use alcohol or illegal drugs
- Get preconception health care and early prenatal health care
- Follow nutritional and other advice carefully, including taking 400 micrograms of folic acid daily
- Maintain a healthy weight
- Avoid exposure to mercury (in fish), lead, and other chemical toxins at work and home
What's being done to improve birth outcomes?
The MDH Center for Health Statistics collects, analyzes, and reports state and county data on a variety of health outcomes, including births and deaths.
The MDH Maternal and Child Health (MCH) Section provides statewide leadership and public health information to promote, improve, and maintain the health of women, children, and families in Minnesota. MCH programs include activities to reduce infant mortality, promote healthy birth outcomes, and support positive parenting.
The Minnesota Pregnancy Risk Assessment Monitoring System (PRAMS) collects and provides data on maternal and child health indicators.
Annual data on birth outcomes are available on the MN Public Health Data Access portal.
The Centers for Disease Control and Prevention provides data and other information about Pregnancy.
