Ensuring Safe Motherhood: The Need for Quality Maternity Care

On By ModernMedia

As we observe Pregnancy Awareness Month this February, it is crucial to reflect on the journey of motherhood and the importance of comprehensive maternity care. According to the latest data from 2024, South Africa’s maternal mortality rate stands at approximately 119 deaths per 100 000 live births1. This statistic underscores the urgent need for improved maternity care services across the country.

Pregnancy is a transformative time, and the right support can make all the difference. From prenatal education to quality healthcare services, expectant mothers require tools and support to navigate this journey confidently. Focus must remain on education, enhancing maternity care services, and addressing the unique challenges faced by South African mothers to ensure that we promote healthy pregnancies and safe motherhood.

Empowering Mothers Through Education

“Education is the cornerstone of empowerment,” says Margot Brews, Head of Health Risk Management Strategy at Momentum Health. “By providing expectant mothers with accurate information about prenatal care, nutrition, and the stages of pregnancy, we can help them make informed decisions that benefit their health and the health of their babies.”

Early antenatal care is crucial, as it allows for the early detection and management of potential complications such as hypertension, diabetes, and infections. In South Africa, where maternal and neonatal mortality rates remain a concern, education can be a powerful tool in reducing these numbers.

Enhancing Maternity Care Services

Quality maternity care is essential for ensuring safe pregnancies and healthy births. In South Africa, access to quality healthcare services can be disparate, with rural areas often facing significant challenges.

“Maternity care is critically important as it directly impacts the health and well-being of both mothers and their babies,” Brews emphasises. “Comprehensive maternity care includes not only medical care but also emotional and psychological support for expectant mothers.”

Early and regular antenatal visits are crucial for detecting and managing potential complications, such as hypertension, diabetes, and infections. Additionally, providing mental health support as part of maternity care can help address anxiety and depression, which are common during pregnancy and postpartum.

Efforts to enhance maternity care services must focus on improving infrastructure in healthcare facilities, training healthcare providers, and ensuring the availability of essential medicines and equipment. “By addressing these challenges, we can create a supportive environment that promotes healthy pregnancies and safe motherhood for all women in South Africa,” Brews adds.

Addressing the Challenges Faced by Mothers

South African mothers face a range of challenges, from financial constraints to social stigma. Teenage pregnancies, in particular, pose significant risks to both the mother and the child. Additionally, teenage mothers often face barriers to continuing their education, which can impact their long-term economic prospects.

“To address these challenges, we must create supportive environments which encourage young mothers to seek prenatal care and continue their education. This should start before pregnancy in the form of guidance and support within the context of broader sexual reproductive health. Community-based programs that provide childcare support, financial assistance, and educational opportunities can make a significant difference in the lives of young mothers and their children,” says Brews.

The Role of Partners and Families

Pregnancy is not only a journey for the mother; it involves the entire family. Partners and families play a crucial role in providing support and creating a nurturing environment for the expectant mother. This involvement can help strengthen the family unit and ensure that the mother receives the emotional and practical support she needs.

“Partners and families are integral to the pregnancy journey, specifically within the cultural context of South Africa,” Brews notes. “Their support can make a significant difference in the emotional and physical well-being of the expectant mother.”

Promoting Maternal Mental Health

Mental health is a critical aspect of maternity care that is often overlooked. Pregnancy and childbirth can be emotionally challenging, and many women experience anxiety, depression, or other mental health strains during this time. It is essential to provide mental health support as part of comprehensive maternity care.

“February presents an opportunity to reflect on the importance of empowering mothers and enhancing maternity care in South Africa,” says Brews. “By working together, we can ensure that every mother has the resources and support she needs for a healthy and positive pregnancy journey.”

Momentum Health believes that by prioritising maternity care, a significant difference can be made in the lives of mothers and their babies. Education and advocating for quality maternity care for all is critical and more must be done to improve maternal care, address disparities in healthcare access, and provide comprehensive support to expectant mothers and mothers in general. “Together, we can make a significant difference in the lives of mothers and their babies, creating a healthier and brighter future,” concludes Brews.

The Importance of Vitamin D during First Trimester

On By ModernMedia

Low vitamin D levels in the first trimester of pregnancy are associated with higher rates of preterm birth and decreased foetal length, according to a new study led by researchers in the Penn State Department of Nutritional Sciences. This research provides evidence that early pregnancy or even preconception may represent critical time points for intervening with women who have low vitamin D status, to optimise pregnancy outcomes.

Celeste Beck, who earned her doctorate in nutritional sciences from Penn State in 2023, and Alison Gernand, Beck’s doctoral adviser and associate professor of nutritional sciences at Penn State, led the study. Their results were recently published in The American Journal of Clinical Nutrition.

“More than 25% of women who are pregnant or lactating have lower than recommended levels of vitamin D,” Gernand said, explaining that prior research has demonstrated the effect of vitamin D on foetal skeletal growth, maternal immune function at the foetal interface, and the development of the placenta in pregnant women. “A lot of the development early in pregnancy requires vitamin D, so we conducted this study to better understand how early-pregnancy vitamin D status is related to pregnancy outcomes.”

Most prior studies on vitamin D status in pregnant women have measured vitamin D concentrations starting in the second trimester or later, the researchers said. The researchers said this study, to their knowledge, is the first to examine both first and second trimester maternal vitamin D status in relation to longitudinal foetal growth and pregnancy outcomes.

The researchers at Penn State partnered with colleagues at the University of Utah to test blood samples from 351 women collected as part of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, which was funded by the National Institute of Child Health and Human Development and recruited pregnant women across the United States between 2010 and 2013.

According to the Institute of Medicine, less than 50nmol/L represents an insufficiency of vitamin D. When the researchers compared outcomes for women with vitamin D insufficiency (less than 50nmol/L) to women with sufficient vitamin D (more than or equal to 50nmol/L), they found no statistical differences in pregnancy outcomes. However, when the researchers compared pregnancy outcomes across a wider range of vitamin D concentrations, they found that pregnant women with first trimester vitamin D concentrations lower than 40 nmol/L were four times more likely to experience a preterm birth compared to women with vitamin D concentrations more than or equal to 80nmol/L.

Despite the higher risk of preterm birth in women with low vitamin D status, the researchers cautioned that these results were based on a very low number of preterm births in this study and recommend that additional, larger studies be conducted.

The researchers also observed an association between first-trimester vitamin D concentrations and certain foetal growth patterns. Women with higher levels of vitamin D experienced a small but statistically significant increase in foetal length.

The Massive Changes to Mothers’ Intestines in Pregnancy and Breastfeeding

On By ModernMedia

When women are pregnant and nurse their babies, their bodies change and various organs, such as the breasts or the immune system, are adapted to ensure the health of both mother and child. This happens throughout evolution in all mammals. An international research team led by Josef Penninger and Masahiro Onji, Medical University of Vienna, now reports the surprising finding that the intestine also changes completely in pregnant and nursing females, resulting in a doubling of the intestinal surface area and a striking structural reorganisation.

Reporting their findings in Nature, the researchers also provide the first genetic and mechanistic evidence of how this intestinal epithelial expansion occurs in mothers, with direct implications for the transgenerational health of the babies.

A multinational team led by Josef Penninger observed that the intestinal villi reorganise during pregnancy and breastfeeding and significantly enlarge, doubling their surface area. The studies were carried out in genetically modified mice and intestinal organoids from mice and humans – self-organised three-dimensional tissues derived from stem cells in the intestine. Mechanistically, the researchers identified the RANK receptor/RANK ligand (RANK/RANKL) system as the key to the villous enlargement of the small intestine during reproduction, which is regulated by sex and lactation hormones. When mice were engineered to lack the RANK/RANKL system in the intestine, the villous expansion during pregnancy and breastfeeding was significantly impaired.

For decades, researchers have studied the RANK/RANKL system as a key facilitator of essential, evolutionarily conserved processes. The Penninger group has already identified key functions of the RANK/RANKL system in bone turnover, in the biology of the mammary gland, in breast cancer, and in immune tolerance in pregnancy, contributing to the development of drugs against bone loss used by millions of people and clinical trials for breast cancer prevention and cancer immunotherapies are underway. The researchers now discovered that these intestinal changes, which appear to be completely reversible when nursing is stopped, are important for proper feeding and nourishment of the babies.

“Our study shows that the impairment of this intestinal expansion by the lack of the RANK/RANKL system during pregnancy changes the milk of the nursing mothers. This results in lower weights of the babies and transgenerational long-term metabolic consequences,” states lead author Masahiro Onji. “Mothers need to eat for themselves and their babies. These new studies provide for the first time a molecular and structural explanation of how and why the intestine changes to adapt to enhanced nutrient demand of mothers, which is probably the case in all pregnant and nursing mammals,” adds study leader Josef Penninger.

How mothers adapt to the demands of pregnancy and breastfeeding remains a central question of evolution and human health. During this phase, female hormones influence multiple organs to control and change their structure and functions, which is crucial for the health of the mother and the development of the offspring. It was known that pregnant women have enhanced nutrient demands. However, this fundamental aspect has not been well studied until now:

“By identifying the RANK/RANKL system as the driving force behind intestinal adaptation during pregnancy and lactation, our study contributes to a deeper understanding of biological processes that are of fundamental importance for evolution and human health”, says Josef Penninger, summarising the impact of the findings.

This massive expansion is controlled by sex and pregnancy hormones, which change the stem cells in the gut via the RANK/RANKL system and then give the intestinal cell a survival signal to grow much larger. This growth then leads to a near doubling of the intestinal surface area, which also increases the molecular machinery for the uptake of sugar, protein, and fat, and even leads to a profound architectural change in the intestinal villi, which probably slows down the flow of food, again maximising the uptake of nutrients.

Josef Penninger said: “Our team has discovered an amazing new way how mother’s bodies change to keep babies healthy. Hardly anybody knew about this, apart from a few old studies that have largely been forgotten. We have also found that this system, via stem cells, can directly affect tumours in the intestine; maybe we can learn from pregnant and nursing mothers to reversibly rewire this system to develop new treatments and a better understanding of intestinal cancer or gut regeneration.”

Pregnancy Enhances Natural Immunity to Block Severe Flu

On By ModernMedia

McGill University scientists have discovered that pregnancy may trigger a natural immunity to boost protection against severe flu infection. Contrary to the common belief that pregnancy increases vulnerability to infections, researchers found that it strengthened an immune defence in mice, blocking the Influenza A virus from spreading to the lungs, where it can cause severe infection.

“Our results are surprising because of the current dogma, but it makes sense from an evolutionary perspective,” said co-lead author Dr Maziar Divangahi, Professor in McGill’s Faculty of Medicine and Health Sciences and Senior Scientist at the Research Institute of the McGill University Health Centre (The Institute).

“A mother needs to stay healthy to protect her developing baby, so the immune system adapts to provide stronger defenses. This fascinating response in the nasal cavity is the body’s way of adding an extra layer of protection, which turns on during pregnancy.”

Exploring benefits for pregnancy and beyond

The researchers used a mouse model to observe how a certain type of immune cell activates in the nasal cavity of mice during pregnancy, producing a powerful molecule that boosts the body’s antiviral defenses, especially in the nose and upper airways.

“Influenza A virus remains among the deadliest threats to humanity,” said first author Julia Chronopoulos, who carried out the research while completing her PhD at McGill. “This natural immunity in pregnancy could change the way we think about flu protection for expectant mothers.”

The Public Health Agency of Canada recommends pregnant women and pregnant individuals get the flu vaccine, as they are at high risk of severe illness and complications like preterm birth. The new insights offer promise for more targeted vaccines for influenza, which is among the top 10 leading causes of death in Canada.

“The broader population could also benefit, as our findings suggest the immune response we observed could be replicated beyond pregnancy,” said co-lead author Dr James Martin, Professor in McGill’s Faculty of Medicine and Health Sciences and Senior Scientist at the RI-MUHC. This could mean new nasal vaccines or treatments that increase protective molecules, known as Interleukin-17.

The team’s next focus is on finding ways to reduce lung damage during viral infections like the flu or COVID. Rather than targeting the virus, as previous research has done, they aim to prevent dysregulated immune systems from overreacting, an approach that could lower the risk of serious complications associated with flu infection.

Researcher Discovers Ancient Egyptian Mugs Contained Hallucinogens

The first-ever physical evidence of hallucinogens in an Egyptian mug has been found, validating written records and centuries-old myths of ancient Egyptian rituals and practices. Through advanced chemical analyses, University of South Florida professor Davide Tanasi examined one of the world’s few remaining Egyptian Bes mugs.

Such mugs, including the one donated to the Tampa Museum of Art in 1984, are decorated with the head of Bes, an ancient Egyptian god or guardian demon worshiped for protection, fertility, medicinal healing and magical purification. Published in Nature’s Scientific Reports, the study sheds light on an ancient Egyptian mystery: The secret of how Bes mugs were used about 2000 years ago. 

“There’s no research out there that has ever found what we found in this study,” Tanasi said. “For the first time, we were able to identify all the chemical signatures of the components of the liquid concoction contained in the Tampa Museum of Art’s Bes mug, including the plants used by Egyptians, all of which have psychotropic and medicinal properties.”

The presence of Bes mugs in different contexts over a long period of time made it extremely difficult to speculate on their contents or roles in ancient Egyptian culture.

“For a very long time now, Egyptologists have been speculating what mugs with the head of Bes could have been used for, and for what kind of beverage, like sacred water, milk, wine or beer,” said Branko van Oppen, curator of Greek and Roman art at the Tampa Museum of Art. “Experts did not know if these mugs were used in daily life, for religious purposes or in magic rituals.”

Several theories about the mugs and vases were formulated on myths, but few of them were ever tested to reveal their exact ingredients until the truth was extracted layer by layer.

Tanasi, who developed this study as part of the Mediterranean Diet Archaeology project promoted by the USF Institute for the Advanced Study of Culture and the Environment, collaborated with several USF researchers and partners in Italy at the University of Trieste and the University of Milan to perform chemical and DNA analyses. With a pulverised sample from scraping the inner walls of the vase, the team combined numerous analytical techniques for the first time to uncover what the mug last held.

The new tactic was successful and revealed the vase had a cocktail of psychedelic drugs, bodily fluids and alcohol – a combination that Tanasi believes was used in a magical ritual re-enacting an Egyptian myth, likely for fertility. The concoction was flavoured with honey, sesame seeds, pine nuts, liquorice and grapes, which were commonly used to make the beverage look like blood.

“This research teaches us about magic rituals in the Greco-Roman period in Egypt,” Van Oppen said. “Egyptologists believe that people visited the so-called Bes Chambers at Saqqara when they wished to confirm a successful pregnancy because pregnancies in the ancient world were fraught with dangers. So, this combination of ingredients may have been used in a dream-vision inducing magic ritual within the context of this dangerous period of childbirth.”

“Religion is one of the most fascinating and puzzling aspects of ancient civilizations,” Tanasi said. “With this study, we’ve found scientific proof that the Egyptian myths have some kind of truth and it helps us shed light on the poorly understood rituals that were likely carried out in the Bes Chambers in Saqqara, near the Great Pyramids at Giza.”

The Bes mug is on display now at the Tampa Museum of Art and can be viewed in the exhibition, “Prelude: An Introduction to the Permanent Collection.” View a 3D model of the Bes mug produced by the USF Institute for Digital Exploration.

Pregnancy may Add Months to a Woman’s Biological Age

On By ModernMedia

Pregnancy may carry a cost, according to a new study involving 1735 young people in the Philippines, and shows that women who reported having been pregnant looked biologically older than women who had never been pregnant, and women who had been pregnant more often looked biologically older than those who reported fewer pregnancies.

Notably, the number of pregnancies fathered was not associated with biological aging among same-aged cohort men, which implies that it is something about pregnancy or breastfeeding specifically that accelerates biological aging. The findings are published in the Proceedings of National Academy of Sciences.
 
This study, from the Columbia University Mailman School of Public Health, builds on epidemiological findings that high fertility can have negative side effects on women’s health and longevity. What was unknown, however, was whether the costs of reproduction were present earlier in life, before disease and age-related decline start to become apparent. Until now, one of the challenges has been quantifying biological aging among the young. This challenge was overcome by using a collection of new tools that use DNA methylation (DNAm) to study different facets of cellular aging, health, and mortality risk. These tools, called ‘epigenetic clocks’ allow researchers to study aging earlier in life, filling a key gap in the study of biological aging.
 
“Epigenetic clocks have revolutionised how we study biological aging across the lifecourse and open up new opportunities to study how and when long-term health costs of reproduction and other life events take hold”, said Calen Ryan, PhD, associate research scientist in the Columbia Aging Center, and lead author.
 
“Our findings suggest that pregnancy speeds up biological aging, and that these effects are apparent in young, high-fertility women,” said Ryan. “Our results are also the first to follow the same women through time, linking changes in each woman’s pregnancy number to changes in her biological age.”
 
The relationship between pregnancy history and biological age persisted even after taking into account various other factors tied to biological aging, such as socioeconomic status, smoking, and genetic variation, but were not present among men from the same sample. This finding, noted Ryan, points to some aspect of bearing children – rather than sociocultural factors associated with early fertility or sexual activity – as a driver of biological aging.
 
Despite the striking nature of the findings, Ryan encourages readers to remember the context: “Many of the reported pregnancies in our baseline measure occurred during late adolescence, when women are still growing. We expect this kind of pregnancy to be particularly challenging for a growing mother, especially if her access to healthcare, resources, or other forms of support is limited.”
 
Ryan also acknowledged that there is more work to do, “We still have a lot to learn about the role of pregnancy and other aspects of reproduction in the aging process. We also do not know the extent to which accelerated epigenetic aging in these particular individuals will manifest as poor health or mortality decades later in life.”
 
Ryan said that our current understanding of epigenetic clocks and how they predict health and mortality comes largely from North America and Europe, but that the aging process can take slightly different forms in the Philippines and other places around the world.

“Ultimately I think our findings highlight the potential long-term impacts of pregnancy on women’s health, and the importance of taking care of new parents, especially young mothers.”

Metformin for Gestational Diabetes may Negatively Impact Offspring

On By ModernMedia

With the rise in gestational diabetes and metabolic disorders during pregnancy, metformin is also being prescribed more frequently. Although it is known that the oral antidiabetic agent can cross the placental barrier, the impacts on the brain development of the child are largely unknown. Now, researchers have been able to demonstrate in a mouse model that although metformin has positive effects in pregnant animals, it does not in the offspring. The researchers, from German Institute of Human Nutrition Potsdam-Rehbrücke (DIfE), published their findings in Molecular Metabolism.

Around one in six pregnant women worldwide are affected by gestational diabetes. According to the Robert Koch Institute, 63 000 women in Germany were affected by the disease in 2021, and the trend is increasing. Excessively high blood sugar levels during pregnancy are associated with negative consequences for mother and child. It increases the risk of affected women developing type 2 diabetes later on and their children have a higher risk of developing metabolic disorders and being overweight.

Long-term effect of metformin on offspring is unclear

The placenta-crossing oral antidiabetic agent metformin has been gaining importance as an alternative to insulin administration when lifestyle changes fail to treat gestational diabetes. But there are currently only a few studies on the long-term effects of metformin on the health of offspring. It is known that metformin has an impact on the AMPK signaling pathway, which regulates the networking of nerve cells during brain development.

The interdisciplinary team of DIfE researchers led by Junior Research Group Leader Dr Rachel Lippert therefore grappled with two central questions:

Firstly, is metformin treatment only beneficial for the mother or also the child?

Secondly, does metformin treatment lead to long-term negative physiological changes in the offspring, especially in connection with the development of neuronal circuits in the hypothalamus, a critical region in the regulation of energy homeostasis?

Mouse models shed some light

To answer the key questions, the researchers used two mouse models with high-fat or control diets to represent the main causes of gestational diabetes, ie, severe obesity of the mother before pregnancy and excessive weight gain during pregnancy. The antidiabetic treatment of female mice and their offspring took place during the lactation period as this corresponds to the third trimester of a human pregnancy in terms of brain development.

The mice were treated with insulin, metformin, or a placebo, with dosage based on standard human treatments. The research team collected data on the body weight of the mice, analysed various metabolic parameters and hormones, and examined molecular signaling pathways in the hypothalamus.

Maternal metabolic state is crucial

“As a result of antidiabetic treatment in the early postnatal period, we were able to identify alterations in the weight gain and hormonal status of the offspring, which were critically dependent on the metabolic state of the mother,” explains Lippert. Furthermore, sex-specific changes in hypothalamic AMPK signalling in response to metformin exposure were also observed. Together with the metformin-induced shift in the examined hormone levels, the results indicate that the maternal metabolic state must be taken into account before starting the treatment of gestational diabetes.

Focusing on prevention

According to Rachel Lippert, treatment of gestational diabetes in future could entail developing a medication that is available for all and does not cross the placenta. “Given the increasing prevalence, education about gestational diabetes and preventive measures are of vital importance. If we can find a way to manage lifestyle and diet more proactively, we are in a better position to exploit the potential of gestational diabetes treatment,” says Lippert.

Study Reveals Great Variability in Pregnant Women’s Body Images

On By ModernMedia

A new study published in the journal BMC Pregnancy and Childbirth has found considerable variability in the ways pregnancy affects women’s perceptions of their own body, including experiences of negative body image.

Negative body image during pregnancy is known to have serious adverse effects on both the mother and baby. Overall, average levels of body image dissatisfaction were found to be similar for pregnant women compared to the general female population, but on an individual basis, the research discovered large differences, both positive and negative.

The study is thought to be the first meta-analysis comparing pregnant and non-pregnant women, and was led by academics from Anglia Ruskin University (ARU) and the University of York.

The researchers initially screened 2017 separate academic studies, before focusing on 17 studies that provided comparable data. In total, the research included 5200 responses from women who were pregnant and 4172 responses from women who were not pregnant.

By synthesising results from multiple studies, the new research found women’s body image dissatisfaction overall was not statistically different during pregnancy compared with when not pregnant. However, when looking at the separate studies that formed part of the meta-analysis, there are significant variations on an individual level.

Body image dissatisfaction in pregnancy is made up of a combination of complex factors related to the positive and negative experiences of each woman, the researchers believe. For some, body image satisfaction will worsen during pregnancy because of ‘feeling fat’, while others describe feeling that their body is out of their control because they are aware their body will change but cannot stop it. Unrealistic portrayals of pregnant women in the media, often edited to remove uneven skin tone and stretch marks, are also believed to contribute to body image dissatisfaction.

Other pregnant women report having improved body positivity compared to when not pregnant, as they no longer compare their body to the ‘thin ideal’. Some say the improvement is because they place less attention on how their body looks and more on its functionality, focusing on the foetus’s health and their maternal role.

Understanding the causes of body image dissatisfaction in pregnant women is important since it can have physical and mental consequences for mother and baby. Many women who display body image dissatisfaction during pregnancy also exhibit depression and anxiety, both postnatally and longer term. This can lead to negative emotional, cognitive, and behavioural outcomes for the child, as well as poor quality mother-infant interactions.

In addition, body image dissatisfaction has been linked with physical illness as the expectant mother may engage in practices such as unhealthy eating, dieting, purging, and fasting. This can have unwanted negative effects on the foetus, such as low birth weight and premature birth.

Lead author Anna Crossland, University of York, said: “Due to the impact that body dissatisfaction can have on the expectant mother and foetus, it is vital to understand how body image dissatisfaction may change on an individual basis when women are pregnant. What our study has found is there is no universal experience during pregnancy, and so we shouldn’t assume how people feel. Pressures about how we look are still felt by some people during pregnancy and it is much more helpful to ask how someone is, rather than commenting on their appearance.”

Co-author Dr Elizabeth Kirk, Senior Lecturer in Psychology at Anglia Ruskin University, said: “Our earlier work found that women who didn’t feel good about their changing bodies in pregnancy reported lower feelings of bonding with their unborn baby. Therefore, it is crucial that we better understand and support women’s body image during pregnancy, to help women on an individual basis.”

Before Birth, Substance Use by Father can Also Increase Risk of Intellectual Disability for Child

On By ModernMedia

Children of a parent with alcohol or drug use disorder have a greater risk of intellectual disability, even if the problem only lies with the father, researchers from Karolinska Institutet report. According to the study, which is published in the journal eClinicalMedicine, preventive measures should be directed at both parents.

A woman’s consumption of alcohol during pregnancy has been well established as increasing the risk of the child developing. Research from Karolinska Institutet now shows that all forms of substance abuse, both in the mother and the father, and not only during pregnancy, can constitute a risk factor.

Previous efforts aimed at mothers

“Preventative measures, such as educating healthcare professionals and public health recommendations, have focused for decades on mothers with alcohol-related problems,” says Lotfi Khemiri, researcher at Karolinska Institutet. “Our findings highlight the importance of also directing such measures towards fathers with different types of substance use disorder.”

The study drew on data from Swedish registries with almost two million babies born between 1978 and 2002 and their parents. The researchers found that 1.2% of babies born to parents without such a disorder were diagnosed with an intellectual disability, compared with 3% of the babies who had one parent with a diagnosis related to a substance use disorder (alcohol or drug abuse).

Higher risk before birth

The elevated risk was greater if the parent had received a diagnosis before or during pregnancy rather than after birth. A substance use disorder diagnosis registered before birth was associated with more than twice the risk of intellectual disability in the baby, regardless of which parent had the diagnosis. The correlation was weaker but still statistically significant after adjustment of socioeconomic factors and psychiatric comorbidity in the parents.

“Since it was an observational study, we can draw no conclusions about the underlying mechanism, but we suspect that both genetic and environmental factors, including harmful effects of substance abuse on foetal development, may play a part,” says Dr Khemiri. “We hope that the results will contribute to the preventative efforts, as well as to the improved diagnosis of children with an intellectual disability and to timely intervention directed both to the child as well as parents in need of substance use disorder treatment.”

Alcohol a major risk factor

Intellectual disability was observed to be much more likely in alcohol-related problems during pregnancy, where the risk was five and three times higher depending on whether it was the mother or father who had the alcohol use disorder diagnosis.

AI Finds Face Shape Changes in Children with in Utero Alcohol Exposure

On By ModernMedia

Using artificial intelligence, researchers have found a link between alterations in the shape of young children’s faces and the amount of alcohol their mothers drank, before and during pregnancy. Even alcohol in small amounts – 12g a week, or less than one glass of wine – made a difference.

The study, published in Human Reproduction, is the first to detect this association in the children of mothers who drank alcohol up to three months before becoming pregnant but stopped during pregnancy.

The finding is important because the shape of children’s faces can be an indication of health and developmental problems.

Study leader Gennady Roshchupkin, assistant professor at Erasmus Medical Centre, Rotterdam, said: “I would call the face a ‘health mirror’ as it reflects the overall health of a child. A child’s exposure to alcohol before birth can have significant adverse effects on its health development and, if a mother regularly drinks a large amount, this can result in foetal alcohol spectrum disorder, FASD, which is reflected in children’s faces.”

FASD is defined as a combination of growth retardation, neurological impairment and recognisably abnormal facial development. Symptoms include cognitive impairment, attention deficit hyperactivity disorder (ADHD), learning difficulties, memory problems, behavioural problems, and speech and language delays. FASD is already known to be caused by a mother’s drinking during pregnancy, particularly heavy drinking. However, until now, little was known about the effect of low alcohol consumption on children’s facial development and, therefore, their health. This is also the first study to examine the question in children from multiple ethnic backgrounds.

The researchers used AI and deep learning to analyse three-dimensional images of children taken at the ages of nine (3149 children) and 13 (2477 children). The children were part of an ongoing population-based study of pregnant women and their children from foetal life onwards. The children in this analysis were born between April 2009 and January 2006.

“The face is a complex shape and analysing it is a challenging task. 3D imaging helps a lot, but requires more advanced algorithms to do this,” said Prof Roshchupkin. “For this task, we developed an AI-based algorithm, which takes high-resolution 3D images of the face and produce 200 unique measurements or ‘traits’. We analysed these to search for associations with prenatal alcohol exposure and we developed heat maps to display the particular facial features associated with the mothers’ alcohol consumption.”

Information on the mothers’ alcohol consumption was gained from questionnaires completed by the women in early, mid-, and late pregnancy. The researchers divided them into three groups: mothers who did not drink before or during pregnancy, mothers who drank during the three months before becoming pregnant but stopped when they became pregnant, and mothers who drank during pregnancy, including those who only drank during the first trimester of pregnancy, and those who continued to drink throughout pregnancy.

“We found a statistically significant association between prenatal alcohol exposure and face shape in the nine-year-old children. The more alcohol the mothers drank, the more statistically significant changes there were. The most common traits were turned-up nose tip, shortened nose, turned-out chin and turned-in lower eyelid,” said Mr Xianjing Liu, first author of the study and a PhD student in Prof Roshchupkin’s group, who developed the AI algorithm.

“Among the group of mothers who drank throughout pregnancy, we found that even if mothers drank very little during pregnancy, less than 12g a week, the association between alcohol exposure and children’s facial shape could be observed. This is the first time an association has been shown at such low levels of alcohol consumption.”

At older ages, the alcohol consumption and face shape association weakened. No significant association was found when the researchers looked at data for the children at the age of 13 years.

“It is possible that as a child ages and experiences other environmental factors, these changes may diminish or be obscured by normal growth patterns. But that does not mean that alcohol’s effect on the health will also disappear. Therefore, it is crucial to emphasise that there is no established safe level of alcohol consumption during pregnancy and that it is advisable to cease drinking alcohol even before conception to ensure optimal health outcomes for both the mother and the developing foetus,” said Prof. Roshchupkin. “Further investigations on the mechanism of association are needed to fully understand how the association develops and then weakens with age.”

In the nine-year-olds, researchers found statistically significant facial traits were associated with mothers’ alcohol consumption when they compared those who drank before pregnancy but stopped on becoming pregnant with mothers who continued drinking throughout pregnancy.

They also looked at data for women who drank during the first trimester but then stopped, and those who continued to drink. The results were similar, which suggests that the associations were explained mainly by the foetus’s exposure to alcohol in the first three months of pregnancy.

According to the researchers, previous studies of childhood development after prenatal exposure to alcohol have suggested that possible mechanisms of action may be metabolic disorders in the mothers, such as problems with blood sugar levels and fatty liver disease, and that this could also explain the link with face shape. However, further investigations are needed.

The large number of children from multiple ethnic backgrounds is a strength of the study. Limitations include that there were no data on alcohol consumption more than three months before pregnancy, and that mothers may not have completed the questionnaire about their drinking habits correctly, possibly underestimating their consumption. Causation also cannot be established in this observational study.
