The long-term health impacts of changing exposure to air pollutants in London

Transport for London (TfL) and the Greater London Authority (GLA) commissioned HealthLumen to quantify the health impacts of policies designed to reduce levels of air pollution and improve long-term health. This 2020 study estimates the number of new cases of disease and the resulting costs to the NHS and social care system under three scenarios from 2016 to 2050. The results from this study show that the ULEZ policies and broader, more all-encompassing LES policies have important impacts on the health of Londoners.

Obesity in primary care: Screening and brief intervention

The Brief Intervention for Weight Loss Trial enrolled consecutively attending primary care patients who were obese and participants were randomised to physicians opportunistically endorsing, offering, and facilitating a referral to a weight loss programme (support) or recommending weight loss (advice). We use a cohort simulation to predict effects on disease incidence, quality of life, and healthcare costs over 20 years.

Inequalities in smoking and obesity in Europe predicted to 2050

This study projected educational inequalities in obesity and smoking prevalence to 2050 based on past obesity and smoking trends by education level. The conclusion was that widening educational inequalities in obesity and smoking prevalence are expected in several European countries if current trends in obesity and smoking prevalence are unaltered. This will impact on inequalities in morbidity and mortality of associated diseases such as diabetes, coronary heart disease and chronic obstructive pulmonary disease.

Forecasting Future Trends in Obesity across Europe: The Value of Improving Surveillance

This project projected the prevalence of obesity across the WHO European region and examined whether the WHO target of halting obesity at 2010 levels by 2025 is achievable. The results were that by 2025, obesity is projected to increase in 44 countries. If present trends continue, 33 of the 53 countries are projected to have an obesity prevalence of 20% or more.

High Rates of Obesity and Non-Communicable Diseases Predicted across Latin America

Non-communicable diseases (NCDs) such as cardiovascular disease and stroke are a major public health concern across Latin America. We used our microsimulation model to project BMI and related disease trends to 2050. We tested the extent to which interventions that decrease body mass index (BMI) have an effect upon the number of incidence cases avoided for each disease. Without intervention obesity trends will continue to rise across much of Latin America.

Alarming predictions for obesity and non-communicable diseases in the Middle East

This study used our microsimulation model to project obesity trends and future obesity-related disease for nine countries in the Middle East. We found that high rates of overweight and obesity increased in both men and women in most countries. Obesity is a growing problem in the Middle East which requires government action on the primary prevention of obesity.

F as in Fat: How obesity threatens America’s future

In this report we modelled the long-term health impacts of obesity in each US state. The results were used as part of an annual report produced by Trust for America’s Health and sponsored by Robert Woods Johnson Foundation.

How would a 20% sugar tax change the UK’s obesity rates?

In 2016, we helped Cancer Research UK show that a 20% sugar-sweetened beverage tax could stop 3.7 million people from becoming obese by 2025. That’s a 5% decrease in national obesity levels. It would save about £10 million in direct NHS healthcare costs in the year 2025 alone.

How much will tackling local air pollution save the NHS?

In 2018, we worked with Public Health England, Imperial College School of Public Health and Imperial College Business School. Together, we created a new tool that helps local authorities estimate how much they could save the NHS by taking action on air pollution.
