Quantifying the case for prevention: disease burden and cost-effective interventions in UK

Area of Science:

• Public Health
• Preventive Medicine
• Health Economics

Background:

• Modifiable lifestyle factors including tobacco use, poor diet, alcohol consumption, physical inactivity, and mental ill-health contribute significantly to the disease burden in the UK.
• National Institute for Health and Care Excellence (NICE) provides evidence on preventive interventions for these risks, highlighting potential for disease prevention and reduction of health inequalities.

Purpose of the Study:

• To estimate the disease burden attributable to behavioral risks and mental health conditions in the UK.
• To identify cost-effective preventive interventions recommended by NICE.
• To assess the prevalence of these risks across different deprivation quintiles.

Main Methods:

• Utilized Global Burden of Disease (GBD) 2021 data to estimate deaths and disability-adjusted life years (DALYs) from behavioral risks and mental health conditions.
• Analyzed national survey data to determine risk prevalence by deprivation quintile.
• Reviewed NICE guidelines to identify cost-effective preventive interventions.

Main Results:

• In 2021, tobacco and dietary risks were leading causes of mortality and disease burden, with tobacco causing nearly 58,000 deaths and diet 48,000 deaths.
• Mental ill-health contributed to low mortality but high DALYs (1.45 million), particularly in younger individuals.
• Risks were generally more prevalent in deprived areas, and NICE-recommended interventions are applicable to millions, especially vulnerable groups.

Conclusions:

• Re-investing in prevention and implementing equitable strategies can substantially decrease disease burden and address health inequalities.
• Targeted and sustained investment in underserved populations and areas is likely to yield the greatest public health gains.
