The Claim

Air pollution and dietary risks are major contributors to ischemic heart disease mortality in low- and middle-SDI regions, with attributable fractions significantly higher than in high-SDI regions, indicating that environmental and nutritional disparities drive regional differences in burden.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In low- and middle-income countries, exposure to air pollution and poor diet directly results in higher rates of death from heart disease compared to high-income countries, due to greater environmental and nutritional risk exposure.

See the scientific wording

Air pollution and dietary risks are major contributors to ischemic heart disease mortality in low- and middle-SDI regions, with attributable fractions significantly higher than in high-SDI regions, suggesting environmental and nutritional disparities drive regional burden differences.

Why this might work

Breathing dirty air and eating unhealthy food over time causes blood vessels to become inflamed and damaged, leading to fatty buildup inside artery walls. This buildup hardens and cracks, triggering blood clots that block blood flow to the heart, causing fatal heart attacks.

  1. Study: Global, regional, and national epidemiology of ischemic heart disease among individuals aged 55 and above from 1990 to 2021: a cross-sectional study

    In poorer countries, more older adults are dying of heart disease because of dirty air and bad diets, while in richer countries, fewer people are dying from these causes thanks to better healthcare and healthier living. The study shows this gap is growing.
