Factors Linked to Pregnancy Inflammation May Be Associated With Dysregulation in Children

Authors: Jean Frazier, Michael O’Shea, et al.

Who sponsored this study?

The Environmental influences on Child Health Outcomes (ECHO) Program, Office of the Director, National Institutes of Health supported this research.

Why was this study needed?

Inflammation is a normal part of the body’s defense to injury or infection. The investigators in this study wanted to find out whether factors known to be linked with inflammation during pregnancy (such as socioeconomic conditions, environmental exposures, and maternal infections) might be associated with emotional, cognitive, and behavioral dysregulation in children after birth. “Dysregulation” in this context refers to children’s attention, anxiety and depression, and aggression being measurably different from what is typically expected for children of their age.

What were the study results?

In this study, several maternal risk factors correlated with inflammation (lower education attainment, pre-pregnancy obesity, prenatal infections, and prenatal tobacco use) were strongly associated with dysregulation in offspring.

Researchers used a tool called the Child Behavior Checklist (CBCL) to measure aggressive behavior, anxiety/depression, and attention problems in children. Approximately 13.4 % of children and adolescents in the study met the criteria for the CBCL Dysregulation Profile. More youth with dysregulation (35%) were born to mothers with prenatal infections compared with 28% of youth without dysregulation.

Some additional maternal factors, including being overweight before pregnancy, lower education attainment, and smoking during pregnancy, were associated with higher likelihoods of childhood dysregulation. Children and adolescents who had a parent or sibling with a mental health disorder were more likely to experience dysregulation. Having a mother with gestational diabetes had no significant association with child dysregulation.

What was the study's impact?

By providing information about how maternal inflammation and relevant risk factors may be associated with dysregulation in a mother’s offspring, this study can help inform interventions to improve child health outcomes.

Who was involved?

This study included 4,595 children and adolescents (ages 6-18 years) from 18 ECHO research sites across the United States.

What happened during the study?

This study assessed perinatal factors known to be related to maternal and neonatal inflammation.

ECHO researchers collected data on maternal factors before and during pregnancy, including information about infections during pregnancy. They used the CBCL to collect parent-reported information about each child’s behavior. CBCL assessments were collected between 2009 and August 31, 2021, and researchers used these assessments to determine whether a child met criteria for the CBCL Dysregulation Profile based on their scores for aggression, anxiety/depression, and attention.

What happens next?

Future studies could focus on identifying the mechanisms that link maternal factors with childhood dysregulation. These studies could also look at whether certain interventions are able to reverse or partially reverse the mechanisms that contribute to the development of dysregulation.

ECHO Study Suggests Substance Use During Pregnancy May Be Linked to Behavior Problems in Children

Authors: Sarah Maylott, et al.

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) program, Office of The Director, National Institutes of Health.

Why was this study needed?

Many studies in the past have been interested in how substance exposures during pregnancy affect childhood behavior. Most of these studies, however, have only focused on a single substance or have only assessed children aged 5 years or younger. The purpose of this study was to find out if types of substances affect a child’s behavior during middle childhood.

What were the study results?

Most children in the study were not exposed to any of the substances considered prior to birth, but those who were tended to be exposed to more than one. Children with substance exposures were more likely than their non-exposed peers to have certain behavior problems in middle childhood. Children exposed to tobacco and alcohol were more likely to display rule-breaking or aggressive behaviors, while children exposed to illegal drugs (cocaine, methamphetamine, heroin) were more likely to have higher rates of anxiety, depression, or withdrawn behaviors. However, not all children exposed to substances had behavioral problems, suggesting that some children may be more resilient than others.

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

What was the study's impact?

Two patterns of substance use during pregnancy were associated with childhood behavior problems. This finding is important because it suggests that researchers can identify children at risk for certain behavioral challenges based on the substances their mothers used during pregnancy. With more research, clinicians may be able to anticipate childhood behavior problems during or shortly after pregnancy based on the kinds of substances the child was exposed to and develop personalized interventions for these children.

Who was involved?

Researchers used data from approximately 2,000 women from 10 ECHO research sites which reported on their substance use during pregnancy. When their children were 6 to 11 years old, a caregiver reported on the child’s behavior. The average age of participating mothers at the time of pregnancy was 28 years old.

What happened during the study?

Using data from 2000 to 2020, the researchers grouped women based on the types of substances they used during pregnancy, including 1) low substance use, 2) mainly tobacco use (with moderate likelihood of using alcohol and marijuana), and 3) illicit use. They then compared children’s behaviors for each of these groups.

What happens next?

Similar large-scale studies are needed that look more closely at how the amount and timing of substance use during pregnancy affect the child’s risk for problem behavior, as well as how the child’s home environment contributes to that risk. Additionally, future studies are needed to identify factors that may increase resiliency in children with prenatal substance exposure.

ECHO Study Suggests Prenatal Exposure to Tobacco, Other Substances Associated With Child Behavior, Reasoning

Authors: Liz Conradt, et al.

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) program, Office of The Director, National Institutes of Health.

Why was this study needed?

Little is known about how a pregnant mother’s exposure to multiple substances, like tobacco, alcohol, or opioids, during pregnancy may be associated with outcomes for their children when they reach middle childhood. Most research looks at the effects of single-substance exposures or focuses on the effects of prenatal exposures on the child’s health exclusively during birth or early childhood. In this study, the research team evaluated the effects of prenatal exposure to multiple substances (alcohol, tobacco, marijuana, and opioids) on children’s reasoning skills and behavior during middle childhood.

What were the study results?

The team identified two groups of children based on their reasoning skills and problem behavior scores. Group 1 had average verbal reasoning skills, average spatial reasoning skills, and normal levels of problem behavior. Children in this group were exposed to fewer substances before birth. Group 2 included children with multiple substance exposures before birth. This group had below average verbal reasoning skills, but average spatial reasoning skills, and higher levels of problem behavior. Children in Group 2 were significantly more likely to be exposed to tobacco before birth. The effects of tobacco exposure on problem behavior and reasoning skills were stronger than expected.

What was the study's impact?

This study suggests that children exposed to tobacco and other substances before birth may be at increased risk for problem behaviors and lower verbal reasoning skill scores during middle childhood. These findings will help pediatricians identify children who are at risk for behavior problems and poorer reasoning skill scores. If replicated, this information might help pregnant women and their doctors to recognize how prenatal tobacco, especially in the context of other substance exposure, might affect their child’s verbal reasoning and behavior in middle childhood.

Who was involved?

This study involved pairs of mothers and their biological children. There were 256 mother-child pairs from two ECHO research sites with locations in Rhode Island, Minnesota, Washington, California, and New York. Children were ages six to 11 at the time of the behavioral and reasoning skills assessments.

What happened during the study?

Researchers collected data on prenatal exposure to substances including alcohol, tobacco, marijuana, and opioids. When the children were between six and 11 years old, their caregivers reported on the presence of problem behaviors such as aggression and anxiety. The researchers also collected data on problem solving skills with words, pictures, and diagrams (verbal and nonverbal reasoning).

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

What happens next?

Moving forward, the team wants to improve their measures of prenatal substance exposure and expand their sample size to include more ECHO participants. Grouping children that have been exposed to substances prenatally can help identify subgroups of children at risk for problem behaviors and low reasoning skill scores.

Gestational Diabetes and Postpartum Depression May Be Linked With Early Childhood Behavior Problems

Authors: Lauren C. Shuffrey, et al.

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) Program, Office of The Director, National Institutes of Health.

Why was this study needed?

Previous research has linked gestational diabetes (a type of diabetes mothers develop during pregnancy) to prenatal and postpartum depression in mothers. However, studies have not examined how the combination of gestational diabetes, prenatal depression, and postpartum depression affect early childhood behavior.

What were the study results?

The study found that gestational diabetes, prenatal maternal depressive symptoms, and postnatal maternal depressive symptoms were each associated with increased child externalizing (e.g., acting out, aggression, hyperactivity) and internalizing (e.g., anxiety, depression) behavior problems. This study also found that gestational diabetes was associated with increased autism behaviors only among children exposed to above average perinatal maternal depressive symptoms. Finally, the researchers observed gestational diabetes was only associated with child behavioral problems for male children, and not for female children.

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

What was the impact?

These findings suggest that children born to mothers who had both gestational diabetes and symptoms of depression during pregnancy should receive additional monitoring for behavioral problems during early childhood.

Who was involved?

This study included 2,379 children from ECHO cohorts located in Colorado, Massachusetts, New York, Pennsylvania, and Tennessee. More than half of participants were male, and 216 participants were born to mothers with gestational diabetes during pregnancy.

More than half of maternal participants were from an underrepresented minority group with 32% self-identifying as Black, 23% as Hispanic, 15% as mixed race, and 4% as Asian.

What happened during the study?

ECHO researchers used the Preschool Child Behavior Checklist (CBCL) to examine the behavior of children ages 2 to 5. They also collected information from the mothers including gestational diabetes diagnosis and self-assessments of depression symptoms during and after pregnancy. The study evaluated how gestational diabetes, prenatal depression, and postpartum depression affected children’s behavioral outcomes using the CBCL.

What happens next?

ECHO researchers are currently analyzing blood samples collected during pregnancy to investigate potential inflammatory mechanisms that may influence the associations between gestational diabetes, maternal depression, and early childhood behavior.

“Eat, Sleep, Console” approach shown to be more effective in caring for newborns with neonatal opioid withdrawal syndrome

Author(s): Leslie Young, Lori Devlin, Stephanie Merhar, et al.

Who sponsored this study?

This clinical trial is a collaboration between the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Program and the NIH’s Eunice Kennedy Shriver Institute of Child Health and Human Development (NICHD), funded through the NIH Helping to End Addiction Long-term® Initiative (HEAL).

What were the study results?

Researchers found that the “Eat, Sleep, Console” (ESC) care approach is more effective for the treatment of infants with neonatal opioid withdrawal syndrome (NOWS) than usual approaches to care. ESC focuses on care without the use of medications, and includes holding, swaddling, and rocking the baby in a quiet, calm environment.

In this clinical trial, infants cared for with ESC were medically ready for discharge after an average of 8.2 days, whereas infants cared for with usual approaches were medically ready for discharge after 14.9 days. That means that babies were, on average, able to go home 6.7 days sooner. Newborns cared for with ESC were also 63% less likely to receive medication as part of their treatment (19.5% in the ESC group received opioid therapy, compared to 52% in the Finnegan Neonatal Abstinence Scoring Tool [FNAST] group). Safety outcomes at three months of age were similar between both groups.

What was the study's impact?

Newborns exposed to opioids before birth may develop symptoms of NOWS. These symptoms may include tremors, excessive crying and irritability, and problems with sleeping and feeding. In the United States, at least one newborn is diagnosed with NOWS every 24 minutes. There has not previously been strong evidence to support a standard approach to the care of babies with NOWS, and medical care for these babies has varied widely across hospitals.

This study gives hospitals an evidence-based approach to care for babies with NOWS. Compared with usual care using traditional scoring approaches, the ESC care approach substantially shortens the time infants spend in the hospital. The ESC approach has also been shown as safe as usual care approaches after discharge through early infancy.

Why was this study needed?

Hospitals have different approaches for caring for these babies. They often use FNAST to assess newborns with NOWS. The FNAST is an extensive scoring system that assesses signs of withdrawal in more than 20 areas. Concerns have been raised about its subjectivity and overestimation of the need for opioid medication.

The ESC care approach was developed about eight years ago and is growing in popularity in some nurseries, but this method had not previously been rigorously tested. ESC assessments are centered on an infant’s ability to eat, sleep and be consoled without the introduction of medications, and this approach keeps mother and baby together, empowering families to play a larger role in the care of their infants. However, the widespread adoption of ESC without solid evidence of its effectiveness and safety has raised concerns about potentially undertreating infants or discharging them too early. This study tested the extent to which ESC might be a better way to care for babies with NOWS.

Who was involved?

The study examined the hospital outcomes of a diverse group of 1,305 opioid-exposed infants from 26 hospitals across the U.S. The study is part of the Advancing Clinical Trials in Neonatal Opioid Withdrawal (ACT NOW) Collaborative, which brings together two existing pediatric research networks: the NICHD Neonatal Research Network and the ECHO Program’s Institutional Development Award (IDeA) States Pediatric Clinical Trials Network (ISPCTN).

What happened during the study?

The researchers randomized 26 hospitals to transition from FNAST-based care to the ESC care approach at different times. They then evaluated each method based on how soon infants were ready to leave the hospital and whether infants were treated with opioid medication to manage their symptoms.

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your healthcare without first consulting your healthcare professional.

What happens next?

The researchers will continue to follow up with a subset of the participating infants for two more years to see if the ESC approach has any effect on infant and family well-being.

Children and Adolescents Born Preterm Were More Likely to Use Healthcare Services Related to COVID-19 Symptoms

Authors: Elisabeth C. McGowan, Monica McGrath, Andrew Law, Barry Lester, et al

Who sponsored this study?

The Environmental influences on Child Health Outcomes (ECHO) Program, Office of the Director, National Institutes of Health supported this research.

Why was this study needed?

This is one of the first studies to look at healthcare use during the COVID-19 pandemic by a high-risk population—children and adolescents who were born preterm (37 or fewer weeks after gestation). By looking for possible patterns of healthcare utilization, this study can help healthcare providers to improve care for patients in future pandemics or other public health care crises.

What were the study results?

In this study, the researchers found that individuals born at 37 or fewer weeks after gestation were more likely to use healthcare services related to COVID-19 symptoms; those born extremely preterm (28 or fewer weeks) were even more likely to do so. For example, children and adolescents born extremely preterm were twice as likely to ask for an in-person appointment or a telehealth evaluation compared to individuals who were born after 37 weeks. Researchers saw that these differences were probably not caused by known risks for breathing problems such as asthma or chronic lung disease. Additionally, preterm children were no more likely to miss healthcare appointments overall than were individuals born at term.

What was the study's impact?

This study suggests that children and adolescents who were born preterm may be more likely to use healthcare during the COVID-19 pandemic than are children and adolescents who were born at full-term. Understanding the factors associated with both overall healthcare use and symptom-specific use may help healthcare providers identify the best strategies to provide targeted care. Understanding the different needs and patterns of healthcare use among children born preterm and their families during the first year of the pandemic, and why those patterns exist, are important first steps on the path to make healthcare more effective and efficient.

Who was involved?

This study included data from 42 ECHO research sites that together included 1,691 individuals ages 1–18 years. Of these individuals, 270 were born at less than 37 weeks of gestation. The study collected data from participants who were on average between 8 and 9 years of age. Approximately 40% of participants born preterm had reports of asthma-like symptoms within 1 year of healthcare use, compared to 20% of those born at term.

What happened during the study?

In this study, the researchers investigated whether children born preterm used healthcare during the COVID-19 pandemic differently than those born at term. Between April 2020 and August 2021, children’s caregivers and adolescents answered questionnaires regarding COVID-19 and healthcare use. The researchers studied healthcare use related to concerns about COVID-19 symptoms (like trouble breathing, fever, headache, muscle pain, fatigue, itchy eyes, nausea, diarrhea, vomiting, and loss of smell or taste) that resulted in overnight stays in hospitals, visits to urgent care centers or primary care offices, or virtual visits such as telehealth. They also explored changes in overall healthcare use during the pandemic, including missed healthcare appointments caused by parental concerns about going into a medical office or cancellation of an appointment by the provider.

Preterm Birth and Family Hardship May Associated With Childhood Behavior Problems

Authors: Julie A. Hofheimer, Monica McGrath, Rashelle Musci, et al.

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) Program, Office of The Director, National Institutes of Health.

Why was this study needed?

Emotional and behavioral difficulties during early childhood can predict later problems such as anxiety, depression, attention deficits, and aggression. This study aims to describe children’s behavioral development from 18 to 72 months of age, examining risk factors for continuing behavioral problems that can inform early interventions to improve behavioral and emotional regulation.

What were the study results?

Children born preterm, males, and those exposed to more family hardships had more behavioral difficulties that persisted over time, including anxiety/depression, attention deficits, and aggression. Other factors that increased the risk for behavioral difficulties in children were prenatal substance exposure and higher maternal psychosocial and economic difficulties during pregnancy. Some children who experienced fewer family hardships showed improved behavior over time when receiving early support. The researchers were able to identify early life factors that may increase a child’s risk for experiencing behavioral and emotional difficulties later in childhood.

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

What was the study's impact?

This study suggested that support and services for families to help them cope with newborn health challenges and other family hardships may help improve young children’s behavioral and emotional difficulties. Specifically, preterm births and prenatal substance exposures may be used to identify children who may benefit from early support. Individualized support to meet the specific needs of children may prevent later behavioral problems and improve future outcomes for vulnerable children and their families.

Who was involved?

The study included 3,934 children born between 1990 and 2019 and their mothers from 20 ECHO cohorts across the United States. About 80% of the children were born at term (at or beyond 37 weeks of gestation), and about 20% were born preterm (before 37 weeks of gestation).

What happened during the study?

The researchers collected caregiver self-reports, demographics, and medical and social environment information about the mothers and children before and during pregnancy and from infancy through age 6. Caregivers also completed the Child Behavior Checklist at multiple study visits to describe their child’s behavior at different ages. Researchers compared the trajectory of children’s scores for dysregulation behaviors (anxiety, depression, attention, and aggression) across the first six years of life. Researchers described three patterns of behavioral trajectories observed in these children 1) high and increased dysregulation (2.3%); 2) borderline and stable dysregulation (12.3%); and 3) low and decreasing dysregulation (85.6%).

What happens next?

Future ECHO studies may examine how the behavior of children continues to develop after six years of age. These new studies could focus on identifying additional risk and protective factors for emotional and behavioral well-being and patterns across middle childhood and adolescence.

Rural Family Satisfaction with Telehealth Delivery of an Intervention for Pediatric Obesity and Associated Family Characteristics

Author(s): Nguyen L, Phan TL, Falini L, Chang D, Cottrell L, Dawley E, Hockett CW, VanWagoner T, Darden PM, Davis AM

Why was this study conducted?

Childhood obesity is a serious health problem in the United States and affects more children from rural areas. Experts recommend treating children with obesity within family-based behavioral groups. However, rural areas often don’t have access to these programs. Telehealth is a way to deliver these programs to rural families, but few studies have looked at family satisfaction with behavioral programs delivered this way or who might benefit most from these visits. This study looked at how parents of children living in rural communities rated their experience with telehealth visits to help their child make healthy lifestyle changes, as well as family characteristics associated with satisfaction.

What was done?

A study was conducted with families of children aged 6 to 11 years with overweight or obesity living in rural areas. Half of the children received the telehealth program and a health newsletter, while the other half received only the health newsletter. After the study, parents of children who received the telehealth visits rated the visits in four areas:

The telehealth technology experience
The comfort and privacy they felt with telehealth
The speed and ease of getting care with telehealth
Their overall satisfaction with telehealth

What was found?

Parents were overall very satisfied with the telehealth visits noting they felt comfortable with the technology and satisfied with the privacy. Parents with lower education and income levels reported the highest levels of satisfaction. Race, ethnic group, and in-home internet access did not affect satisfaction ratings.

What do the results mean?

These results show that families from rural areas like telehealth visits and that telehealth might be a good way to increase access to treatment for children with overweight or obesity, especially among disadvantaged communities. There are still barriers to overcome, such as health literacy and access to broadband internet and devices. Larger studies are needed to better understand who might benefit most from telehealth.

Who sponsored the study?

ECHO Study Suggests Most Prenatal Vitamins May Not Provide All of the Nutrients Pregnant Women Need

Authors: Katherine Sauder, et al.

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) Program, Office of The Director, National Institutes of Health.

What were the study results?

Out of all the prenatal supplements analyzed, the study found one that may potentially give pregnant patients the optimal amounts of the most important nutrients. But, the monthly cost of this supplement can be too high for some people, and it requires pregnant women to take seven pills a day. To ensure that pregnant women have accessible options for prenatal vitamins, the researchers looked for dietary supplements containing close to the needed amounts of nutrients that cost less and required only one to two pills a day.

See the full publication (Appendix A) for a list of the prenatal supplements analyzed during this study and their nutritional contents.

Footnote: Results reported here are for a single study. Other or future studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

What was the study's impact?

This study can inform pregnant women and their doctors about key nutrients they may be missing in their diet and what prenatal vitamins they can take to get those nutrients. Companies that manufacture prenatal vitamins can also use the results of this study to understand how much of these nutrients should be in the products they make. Importantly, this study highlights the ongoing need for more prenatal vitamin options that are low cost and convenient, while still containing the optimal amounts of key nutrients.

Why was the study needed?

It is important that pregnant women get the right amounts of the nutrients they need for a healthy pregnancy. There are thousands of options for prenatal dietary supplements in the United States, so ECHO researchers conducted this study to help pregnant women and doctors pick the ones that contain optimal doses of key micronutrients to support a healthy pregnancy.

Who was involved?

This study included 2,450 pregnant participants from six ECHO cohorts located across the United States.

What happened during the study?

ECHO researchers first analyzed data about what the participants ate and drank during their pregnancies. Then, they calculated how much vitamin A, vitamin D, folic acid, calcium, iron, and omega-3 fatty acids the pregnant participants were getting from their diet. The researchers compared the participants’ diets to nutrition recommendations for pregnancy to determine the amount of nutrients the participants would need from a prenatal vitamin to make up what they were missing in their diet.

The researchers compared over 20,000 prenatal vitamins available in the US, focusing on the nutrients that are most important for maternal and infant health: vitamin A, vitamin D, folic acid, calcium, iron, and omega-3 fatty acids.

What happens next?

In addition to the use of prenatal dietary supplements, pregnant women can adjust their diet to include more of the nutrients they need for a healthy pregnancy. Going forward, more research is needed to identify foods that pregnant women could eat to get enough of these nutrients.

ECHO Study Links Maternal Health Factors With Newborn Metabolism and Child Body Mass Index

Authors: Britt Snyder, Tina Hartert, James Gern, et al.

Who sponsored this study?

The Environmental influences on Child Health Outcomes (ECHO) Program, Office of the Director, National Institutes of Health supported this research.

Why was this study needed?

Few studies have looked at possible links between maternal health characteristics, including environmental stressors, and the metabolism of newborns. Metabolism refers to chemical reactions that take place within the cells to provide the body with the energy needed for growth and maintaining health. Researchers often study metabolism by measuring the blood levels of certain molecules—called metabolites—that are created during those chemical processes.

This study expanded previous findings that showed links between maternal characteristics (such as pre-pregnancy smoking, pre-pregnancy body mass index, education, occupation status, marital status, age at delivery, asthma diagnosis, diabetes during pregnancy, or type of delivery) and amounts of metabolites in newborns. The study also explored the link between these metabolites and child growth patterns. In addition, this study explores the maternal factors and potential series of chemical changes in utero (in the womb) that may contribute to the link between newborn metabolism and childhood BMI*.

*Body Mass Index (BMI) is a common health screening tool that considers both height and weight.

What were the study results?

The researchers identified links between maternal health characteristics and the concentration of various metabolites in newborns. Additionally, this study showed that some metabolites were also linked to childhood BMI at ages 1–3 years.

The study found that factors like higher BMI before pregnancy or maternal age at delivery seemed to increase the levels of key metabolites in newborns. However, other metabolites which were linked with maternal health characteristics were not associated with changes in childhood BMI.

What was the study's impact?

Previous research has shown associations between levels of some newborn metabolites and childhood growth, overweight, and obesity. This study provides additional insights on the maternal factors and potential in utero pathways connecting newborn metabolism and later metabolic dysfunction in children. Such imbalance may increase a person’s lifetime risk of coronary heart disease, diabetes, stroke, and other serious health problems.

Who was involved?

This study included 3,492 infants enrolled in three ECHO research sites with linked newborn screening metabolic data.

What happened during the study?

The researchers used data on maternal health characteristics collected from questionnaires, birth certificates, and medical records. Child BMI was obtained from medical records and study visits. The researchers used statistical tools to evaluate possible links between maternal health characteristics and newborn metabolism.

What happens next?

This study is an early step in assessing biological pathways through which maternal health characteristics may influence prenatal metabolic development. These metabolic changes may then influence health after birth. Future studies are needed to further explore the potential pathways through which maternal health characteristics may impact child health.
