Leading Global Mortality Causes and Modifiable Lifestyle Risk Factors

WHO data: top causes of death globally are cardiovascular diseases, cancers, chronic respiratory diseases, diabetes, and dementia/mental disorders.

Modifiable Risk Factors (Shared Across Conditions)

Risk Factor	Impact
Tobacco use	CVD, cancer, COPD, diabetes complications
Unhealthy diet	High sodium, low fruit/veg, trans fats → CVD, cancer, diabetes
Physical inactivity	CVD, diabetes, colon/breast cancer, osteoporosis
Harmful alcohol use	Liver disease, cancer, injury, CVD
Air pollution	COPD, lung cancer, CVD, stroke
Overweight/obesity	Diabetes, CVD, 13 cancers
Raised blood pressure	Stroke, IHD, CKD
Raised glucose	Diabetes complications, CVD
Raised cholesterol	Atherosclerosis

Actionable Lifestyle Pillars

• 7–9 hours sleep
• Mediterranean/DASH diet
• 150 min moderate + 2× strength training/week
• Zero tobacco; limit alcohol
• Stress management (mindfulness, therapy)
• Regular preventive screening (BP, lipids, glucose, cancer)

Clinical Approach

Assess individual risk (ASCVD, FINDRISC, etc.); prioritize highest-impact changes; use shared decision-making; refer to dietitian, PT, cessation programs.

Up to 80% of premature CVD/stroke/diabetes preventable through lifestyle.
