How Health Age is Calculated
Health Age = Chronological Age + Lifestyle Adjustments
Key Factors:
- Smoking Status: +5 to +10 years for current smokers
- Physical Activity: -5 years for very active, +5 years for sedentary
- Diet Quality: -5 years for excellent diet, +5 years for poor diet
- Sleep: -2 years for optimal sleep (7-8 hours), +3 years for poor sleep
- Stress Level: -2 years for low stress, +3 years for high stress
- Alcohol: +5 years for heavy consumption
- Medical Factors: +3 to +5 years for high blood pressure or family history
Example Calculation
Real-World Scenario:
John is a 45-year-old male who wants to know his health age. He's a former smoker who exercises moderately, eats a reasonably healthy diet, but gets only 6 hours of sleep per night and has high stress levels.
Given:
- Chronological Age = 45 years
- Smoking Status = Former smoker (+3 years)
- Physical Activity = Moderate activity (-1 year)
- Diet Quality = 60/100 (average) (+0 years)
- Sleep Hours = 6 hours (+2 years)
- Stress Level = 80/100 (high) (+2 years)
- Alcohol Consumption = Light (+0 years)
- High Blood Pressure = Yes (+3 years)
- Family History = No (+0 years)
Calculation:
Health Age = 45 + 3 - 1 + 0 + 2 + 2 + 0 + 3 + 0 = 54 years
Result: John's health age is 54 years, which is 9 years older than his chronological age. This suggests his lifestyle factors are accelerating his aging process.
