Lifestyle: the four daily levers that matter most
Decades of evidence (NHG, WHO) point to four daily factors that explain most modifiable health risk. None of them alone defines someone — but together, and combined with biomarkers, they predict who needs attention.
The four core factors
Preventa scores these the way Dutch primary care does: isolated cases are usually fine; combinations and severity trigger follow-up.
- •Smoking — the single largest avoidable risk
- •Alcohol — pattern and weekly load
- •Physical activity — minutes per week vs. WHO targets
- •Diet — fruit, vegetable and ultra-processed intake
How lifestyle amplifies biomarker risk
Lifestyle factors rarely cause one isolated problem. They amplify the silent conditions already developing — for example, smoking compounds cardiovascular risk on top of cholesterol, and inactivity compounds metabolic risk on top of glucose.
