EnviroHealth Podcast - Season 2, Episode 3: Dr. Sabena Kagalwalla on 'The Childhood Health Crisis: From Deprivation to Digital Age Challenges'
Host Dr. Joseph Levermore speaks with Dr. Sabena Kagalwalla, consultant paediatrician and innovation fellow at Guy's and St. Thomas' NHS Foundation Trust. They examine why the UK has fallen from world leader to 30th out of 49 OECD countries in infant mortality, and explore the complex web of factors undermining children's health in the 21st century.
Topics Covered:
- How the UK built its paediatric health leadership through hygiene, vaccination, and universal healthcare
- The stark reality: 700 preventable child deaths annually linked to social deprivation
- Rising lifestyle-based pathologies replacing traditional genetic conditions
- Type 2 diabetes now appearing in children - a phenomenon virtually unknown during medical training
- Mental health crises hitting younger ages: suicide attempts in children as young as 10-11
- The lost generation of breastfeeding knowledge and its impact on infant mortality
- How single-parent families, dual-income pressures, and housing instability create health vulnerabilities
- Social media's double-edged impact on developing brains and adolescent mental health
- The intersection of culture, technology, and generational gaps in healthcare
Key Insights:
- Children now present with constipation and abdominal pain as early indicators of lifestyle-related health issues
- Healthcare systems designed for acute medical conditions struggle with multifactorial social problems
- Frontline paediatric staff lack training for adolescent mental health, sexual health, and substance use discussions
- Nordic countries demonstrate how early investment in family support creates healthier populations
- Technology provides unprecedented access to health information while simultaneously creating new vulnerabilities
The Prediction Pattern: Dr. Kagalwalla reveals how toddler constipation can predict later obesity, dental problems, behavioural issues, and eating disorders - a cascade that healthcare systems aren't equipped to interrupt.
Quotes: "When I was training, you would never see someone with type 2 diabetes during their paediatric lifespan. Now you are getting patients with type 2 diabetes before the age of 18."
"It's not as simple as throwing a medication at it anymore. It's almost not as simple as throwing a load of money at it either."
"We're living in an age where the differences between grandparents and parents and their children are massive, and we have not been able to build our healthcare systems to address these problems."

In this environmental health short, Dr. Gary Fuller shares powerful firsthand accounts of the devastating London smog of 1952, including his own father's harrowing experience navigating through air pollution so thick people couldn't see their own feet. Learn how this catastrophic air pollution event killed thousands—estimates ranging from 4,000 to 12,000 victims—making it London's deadliest environmental disaster prior to COVID-19, surpassing both WWII bombing casualties and Victorian cholera outbreaks.
Air Pollution Topics Covered:
- The formation and deadly impact of the "pea souper" air pollution that descended on London December 5, 1952
- Personal stories of surviving through the impenetrable smog, including cinemas where screens were obscured by pollution
- Dr. Fuller's father's experience helping a lost lorry driver just 500 meters from his depot in hazardous air quality
- Comparison of historical air pollution portrayals (including The Crown's recreation) with the actual environmental health crisis
- How this air pollution disaster catalyzed changes in environmental health policy and air quality management
- Historical context of occupational exposures to air pollution, particularly asbestos, and their health impacts
Environmental Health Discussion Highlight: "It was a huge environmental disaster. But it set about a change in the way in which we recognize air pollution as being harmful to health, and the way in which we manage air quality."
