Promoting healthy populations as a pandemic preparedness strategy: a simulation study from Mexico.

Publication date: Feb 01, 2024

The underlying health status of populations was a major determinant of the impact of the COVID-19 pandemic, particularly obesity prevalence. Mexico was one of the most severely affected countries during the COVID-19 pandemic and its obesity prevalence is among the highest in the world. It is unknown by how much the COVID-19 burden could have been reduced if systemic actions had been implemented to reduce excess weight in Mexico before the onset of the pandemic. Using a dynamic epidemic model based on nationwide data, we compare actual deaths with those under hypothetical scenarios assuming a lower body mass index in the Mexican population, as observed historically. We also model the number of deaths that would have been averted due to earlier implementation of front-of-pack warning labels or due to increases in taxes on sugar-sweetened beverages and non-essential high-energy foods in Mexico. We estimate that 52. 5% (95% prediction interval (PI) 43. 2, 61. 6%) of COVID-19 deaths were attributable to obesity for adults aged 20-64 and 23. 8% (95% PI 18. 7, 29. 1%) for those aged 65 and over. Had the population BMI distribution remained as it was in 2000, 2006, or 2012, COVID-19 deaths would have been reduced by an expected 20. 6% (95% PI 16. 9, 24. 6%), 9. 9% (95% PI 7. 3, 12. 9%), or 6. 9% (95% PI 4. 5, 9. 5%), respectively. If the food-labelling intervention introduced in 2020 had been introduced in 2018, an expected 6. 2% (95% PI 5. 2, 7. 3%) of COVID-19 deaths would have been averted. If taxes on sugar-sweetened beverages and high-energy foods had been doubled, trebled, or quadrupled in 2018, COVID-19 deaths would have been reduced by an expected 4. 1% (95% PI 2. 5, 5. 7%), 7. 9% (95% PI 4. 9, 11. 0%), or 11. 6% (95% PI 7. 3, 15. 8%), respectively. Public health interventions targeting underlying population health, including non-communicable chronic diseases, is a promising line of action for pandemic preparedness that should be included in all pandemic plans.
