written by Dr. Priya Deshmukh - Senior Editor, Health

The prevalence of overweight and obesity among U.S. Youth continues to be a significant public health challenge, with nearly one in five children and adolescents affected, according to a recent report published in JAMA Network Open. The findings, based on an analysis of electronic health records from over 6 million children, underscore the urgent need for increased investment in prevention, family support, and proactive healthcare systems.

Childhood obesity, often established early in life, is linked to a range of long-term health issues. Researchers, led by William Heerman, MD, MPH, associate professor of Pediatrics at Monroe Carell Jr. Children’s Hospital at Vanderbilt, examined data from the PCORnet network in 2024 to assess the current scope of the problem. Their analysis reveals a concerning trend, with rates varying by age and sex.

The study found that 19.8% of U.S. Youth aged 2-19 are affected by obesity. Breaking down the numbers further, 26.9% of children aged 2-5 are classified as overweight or obese, while the rate climbs to 38.5% for adolescents aged 12-19. Notably, severe obesity affects 9.2% of adolescents and young adults, highlighting a particularly vulnerable segment of the population. These figures emphasize the growing need for targeted interventions and support systems.

“Obesity in childhood is common and serious, but modifiable,” said Heerman, holder of the William K. Warren Foundation Chair in Medicine. “This research highlights the importance of continued investment in prevention, family support, and systems that enable proactive care. Clinicians need timely, accurate prevalent data to identify early warning signs, counsel families effectively, initiate evidence-based treatment, and support prevention-focused systems of care.”

Key Findings on Youth Weight Status

The research team’s analysis of PCORnet data provides a detailed snapshot of youth weight status across the country. The data underscores the need for a multi-faceted approach to address this complex issue. Early identification and treatment are crucial, aligning with current pediatric guidelines, and effective tools and treatments are available, though access remains a challenge for many families.

Heerman emphasized that systems-level improvements, including digital supports and coordinated care models, can significantly improve outcomes. “Families are not alone,” he stated. “Effective treatments, including behavioral programs, nutrition counseling, and when appropriate, medications, are available and increasingly supported by guidelines.”

The Importance of Early Intervention

The study’s findings reinforce the critical role of early intervention in addressing childhood obesity. Pediatricians and other healthcare providers are increasingly focused on identifying at-risk children and providing families with the resources they need to make healthy lifestyle changes. This includes promoting healthy eating habits, encouraging regular physical activity, and addressing underlying behavioral factors that may contribute to weight gain.

The use of electronic health records, like those analyzed in this study, is proving invaluable in tracking obesity rates and identifying trends. This data can inform public health initiatives and help tailor interventions to specific populations. The PCORnet network, which provided the data for this research, is a valuable resource for understanding and addressing a wide range of health challenges.

Looking ahead, continued research and investment in prevention programs are essential to reversing the trend of rising youth obesity rates. Collaboration between healthcare providers, schools, communities, and families will be crucial in creating a healthier future for all children. The findings from this study serve as a call to action for policymakers, healthcare professionals, and families alike.

Infant Formula Fats Linked to Liver Disease in New Study

by Dr. Priya Deshmukh - Senior Editor, Health
written by Dr. Priya Deshmukh - Senior Editor, Health

Concerns are growing about the potential long-term health effects of infant formula, with a new study suggesting a link between certain fats commonly used in these products and the development of fatty liver disease in infants. Researchers at Virginia Tech have found that medium-chain fatty acids (MCFAs), often derived from coconut oil, may contribute to faster fat accumulation in the liver of newborn pigs compared to long-chain fatty acids (LCFAs) found in animal fats. This finding raises important questions about the composition of infant formulas and the impact of early nutrition on liver health.

Steatotic liver disease, formerly known as non-alcoholic fatty liver disease, is a condition characterized by excess fat buildup in the liver. While historically associated with obesity in adults, diagnoses are increasingly being made in children and even infants, prompting scientists to investigate the role of early-life dietary factors. The Virginia Tech study, published in the American Journal of Physiology-Endocrinology and Metabolism, sheds light on how different types of fats may affect liver metabolism during this critical developmental period.

The research team utilized a neonatal pig model, chosen since their digestive systems and fat metabolism closely resemble those of human infants. Pigs were fed either a formula rich in MCFAs or one rich in LCFAs, while maintaining equal calorie and protein intake. Within just seven days, the piglets fed the coconut oil-derived formula – rich in MCFAs – began to show signs of fat accumulation in their livers. By two weeks, this had progressed to a more severe inflammatory form of the disease, according to lead researcher Samer El-Kadi, associate professor at the School of Animal Sciences at Virginia Tech. “Even within seven days, we could observe fat starting to build up in the liver. By about two weeks, it had progressed from simple steatosis to a more severe inflammatory form of the disease,” El-Kadi stated.

What makes this finding particularly noteworthy is the difference in how the developing liver responds to fat accumulation compared to the adult liver. Traditionally, fat buildup in adults occurs when the liver slows down its fat-burning process. However, the study revealed that in developing livers, fat accumulated even as fat burning increased. “We saw the liver activate both fat-making and fat-burning pathways at the same time. Even with those adaptive responses, the developing liver became overwhelmed. That was surprising to us. Based on what we know from adult disease, increased fat burning should have been protective,” explained El-Kadi.

The Role of Medium-Chain vs. Long-Chain Fatty Acids

Infant formulas commonly utilize blends of plant-based oils to mimic the fat composition of breast milk. The study specifically compared formulas differing only in their fat source. The formula containing MCFAs was derived from coconut oil, while the other used animal fat, providing LCFAs. Researchers found that piglets fed the MCFAs accumulated liver fat at a faster rate than those fed LCFAs.

While breast milk remains the “gold standard” for infant nutrition, formula is often a critical and life-saving alternative when human milk is unavailable. El-Kadi emphasized that the goal of this research is not to discourage formula utilize, but rather to improve its composition. “The immediate benefits of feeding far outweigh any potential long-term risks. Our goal is not to discourage formula use. It’s to understand how different components of formulas affect the developing body, so they can be improved over time,” he said.

The findings underscore the importance of understanding how early nutrition shapes liver metabolism. Further research is needed to determine the long-term consequences of MCFA exposure in infant formula and to identify optimal fat compositions for infant nutrition.

Innovation in Infant Nutrition

The focus on improving infant nutrition is gaining momentum within the industry. Recently, US-based MaiaMilk launched a shelf-stable, medical-grade human donor milk powder, previously only available in neonatal intensive care units. This product, unlike traditional formulas that attempt to replicate breast milk synthetically, is made entirely from human donor milk and can now be used at home after hospital discharge.

As research continues to unravel the complexities of infant liver development and the impact of dietary fats, We see likely that we will see further innovations in infant formula designed to promote optimal health outcomes. The ongoing investigation into the role of MCFAs and LCFAs represents a crucial step towards ensuring that all infants have access to the best possible nutrition for healthy growth and development.

Poorer Gut Health Linked to Deprivation in UK Study

by Dr. Priya Deshmukh - Senior Editor, Health
written by Dr. Priya Deshmukh - Senior Editor, Health

The bacteria in our guts play a surprisingly significant role in both our physical and mental wellbeing, influencing everything from energy levels and blood sugar control to mood regulation and even anxiety. But new research suggests that access to a diverse and healthy gut microbiome isn’t equal across all communities. A recent study has revealed a stark connection between socioeconomic deprivation and gut health, finding that individuals living in the poorest areas of the UK harbor less diverse gut bacteria compared to their more affluent counterparts.

This isn’t simply a matter of differing diets or lifestyles, researchers say. The study, conducted by academics at King’s College London and the University of Nottingham, points to a potential biological pathway linking social disadvantage to poorer health outcomes. Understanding this connection could be crucial in developing targeted interventions to address health inequalities that persist across the UK.

The research team analyzed gut bacteria samples from 1,390 female twins across the UK, cross-referencing this data with their residential postcodes and the Townsend Deprivation Index, a measure of socioeconomic status that considers factors like unemployment and overcrowding. Their findings, published recently, identified 12 bacterial species associated with living in more deprived areas. Notably, two species – Lawsonibacter and Intestinimonas massiliensis – were negatively correlated with deprivation and also linked to higher rates of anxiety and diabetes.

The Gut-Brain Connection and Butyrate Production

These specific bacterial species are significant because they typically produce butyrate, a short-chain fatty acid vital for maintaining energy balance and regulating blood sugar levels. Reduced levels of butyrate-producing bacteria could, contribute to the increased risk of metabolic and mental health issues observed in more deprived communities. Approximately 95% of serotonin, a key neurotransmitter regulating mood, is produced in the gut, further highlighting the intricate link between gut health and mental wellbeing.

Dr. Cristina Menni, senior author of the study and a senior lecturer in molecular epidemiology at King’s College London, emphasized the emerging nature of this research area. “Although Here’s still an emerging area of research, we know that the diversity of bacteria in the gut plays an vital role in overall health,” she stated. “Health inequalities remain one of the biggest challenges facing the UK, and we still do not fully understand how social disadvantage translates into poorer health. Our findings suggest that people who live in more socially deprived areas of the UK may have less diverse gut microbiomes, and that this may be one biological pathway linking deprivation to worse physical and mental health outcomes. We hope that this might lead to interventions that support gut health and help improve overall wellbeing.”

Environmental and Social Factors at Play

The study’s first author, Dr. Yu Lin, a research associate at King’s College London, suggests that the gut microbiome may be a key mechanism through which environmental and social circumstances impact health. “These microbes, in turn, influence how the body processes energy and communicates with the brain,” Dr. Lin explained. “This suggests that social and environmental disadvantage may become biologically embedded through changes in gut bacteria.” Factors such as chronic stress, financial strain, and limited access to nutritious food are all believed to contribute to these changes.

Researchers are now exploring potential interventions aimed at improving gut health in disadvantaged communities. While the exact strategies remain to be determined, possibilities include promoting access to affordable, healthy food, reducing stress through community support programs, and potentially even targeted probiotic or prebiotic interventions. Further research is needed to determine the most effective approaches.

The findings underscore the complex interplay between social determinants of health and biological processes. Addressing health inequalities requires a multifaceted approach that considers not only access to healthcare but also the broader social and environmental factors that shape our wellbeing. As research continues to unravel the intricate connections between the gut microbiome and overall health, it’s becoming increasingly clear that a healthy gut is not just a matter of individual choices, but a matter of social justice.

France’s Blood Supply: How Donations Directly Impact Patient Care

The French blood service, Établissement français du sang (EFS), plays a critical role in ensuring a stable and safe blood supply for the nation. Beyond simply collecting donations, the EFS functions as a key player in the broader healthcare economy, transforming those donations into life-saving treatments for approximately one million patients annually. This complex operation relies heavily on volunteer donors and a sophisticated logistical network to meet the ongoing demands of hospitals and medical facilities across France.

The EFS isn’t just a recipient of donations; it actively participates in what’s often described as the “sharing economy,” efficiently managing resources to maximize impact. This involves not only the collection, testing, and processing of blood, but also the production of a range of blood products, including red blood cells, platelets, and plasma. These components are then distributed to hospitals, where they are used in a wide variety of medical procedures, from emergency trauma care to cancer treatment and complex surgeries.

Understanding the scale of this operation requires recognizing the constant need for new donors. Recent reports highlight the urgent need for 5,000 additional plasma donors in the PACA region of France alone, demonstrating the ongoing challenges in maintaining sufficient supply to meet patient needs. Monaco Life reported on this critical shortage, emphasizing the direct link between donor participation and patient outcomes.

Plasma, a key component of blood, is particularly vital for treating a range of conditions, including immune deficiencies, bleeding disorders, and burn victims. The process of collecting plasma, known as plasmapheresis, is carefully monitored to ensure donor safety. Recent research, including a systematic review published in medRxiv, examines the impact of plasmapheresis frequency on donor health, highlighting the importance of balancing collection needs with the well-being of those who donate.

The EFS also actively engages with the public through platforms like YouTube, providing information about blood donation, the importance of plasma, and the impact of their work. This outreach is crucial for raising awareness and encouraging participation.
