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.

The Brighton declaration: the value of non-communicable disease modelling in population health sciences

The Brighton declaration arose out of a one day workshop held in September 2013 as part of the Society for Social Medicine annual conference. The declaration describes the value and importance of non-communicable disease modelling, both for research and for informing health policy. This article, written by the UK Health Forum modelling department, discusses the declaration.

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.
