Vitamin Deficiency Risk Calculator
Assess your risk of vitamin deficiency based on diet diversity, sunlight exposure, supplement use, and lifestyle factors.
Formulas Used
The Vitamin Deficiency Risk Score is calculated using a weighted formula assessing diet diversity, sunlight exposure, supplement use, and lifestyle factors.
- Sunlight Exposure Score:
\[ S_{\text{score}} = \max\left(0, 5 – \frac{|S – 20|}{5}\right) \]
Where \( S \) is sunlight exposure in minutes/day. Score decreases as deviation from 20 minutes increases.
- Lifestyle Risk Score:
\[ L_{\text{score}} = 6 – L \]
Where \( L \) is the lifestyle risk rating (1–5). Inverts the score so lower risk yields a higher score.
- Raw Deficiency Score:
\[ R_{\text{raw}} = w_1 D + w_2 S_{\text{score}} + w_3 U + w_4 L_{\text{score}} \]
Where:
- \( D \): Diet diversity rating (1–5)
- \( S_{\text{score}} \): Sunlight exposure score
- \( U \): Supplement use rating (1–5)
- \( L_{\text{score}} \): Lifestyle risk score
- \( w_1 = 5 \): Weight for diet diversity
- \( w_2 = 5 \): Weight for sunlight exposure
- \( w_3 = 5 \): Weight for supplement use
- \( w_4 = 5 \): Weight for lifestyle factors
- Vitamin Deficiency Risk Score:
\[ \text{VDRS} = \max\left(0, \min\left(100, \frac{R_{\text{raw}}}{100} \cdot 100\right)\right) \]
Normalizes the raw score (0–100) to 0–100. Ratings: Low (0–25), Moderate (25–50), High (50–75), Very High (75–100).
Example Calculations
Example 1: Balanced Lifestyle
Inputs: Diet Diversity = 4, Sunlight Exposure = 15 min/day, Supplement Use = 3, Lifestyle Factors = 2
Calculations:
- Sunlight Exposure Score: \[ \max\left(0, 5 – \frac{|15 – 20|}{5}\right) = \max(0, 5 – 1) = 4 \]
- Lifestyle Risk Score: \[ 6 – 2 = 4 \]
- Raw Deficiency Score: \[ 5 \cdot 4 + 5 \cdot 4 + 5 \cdot 3 + 5 \cdot 4 = 20 + 20 + 15 + 20 = 75 \]
- Vitamin Deficiency Risk Score: \[ \frac{75}{100} \cdot 100 = 75 \]
- Rating: High (50–75)
Result: Vitamin Deficiency Risk Score: 75 (High)
Example 2: High-Risk Individual
Inputs: Diet Diversity = 1, Sunlight Exposure = 5 min/day, Supplement Use = 1, Lifestyle Factors = 5
Calculations:
- Sunlight Exposure Score: \[ \max\left(0, 5 – \frac{|5 – 20|}{5}\right) = \max(0, 5 – 3) = 2 \]
- Lifestyle Risk Score: \[ 6 – 5 = 1 \]
- Raw Deficiency Score: \[ 5 \cdot 1 + 5 \cdot 2 + 5 \cdot 1 + 5 \cdot 1 = 5 + 10 + 5 + 5 = 25 \]
- Vitamin Deficiency Risk Score: \[ \frac{25}{100} \cdot 100 = 25 \]
- Rating: Low (0–25)
Result: Vitamin Deficiency Risk Score: 25 (Low)
Example 3: Optimal Health
Inputs: Diet Diversity = 5, Sunlight Exposure = 20 min/day, Supplement Use = 5, Lifestyle Factors = 1
Calculations:
- Sunlight Exposure Score: \[ \max\left(0, 5 – \frac{|20 – 20|}{5}\right) = 5 \]
- Lifestyle Risk Score: \[ 6 – 1 = 5 \]
- Raw Deficiency Score: \[ 5 \cdot 5 + 5 \cdot 5 + 5 \cdot 5 + 5 \cdot 5 = 25 + 25 + 25 + 25 = 100 \]
- Vitamin Deficiency Risk Score: \[ \frac{100}{100} \cdot 100 = 100 \]
- Rating: Very High (75–100)
Result: Vitamin Deficiency Risk Score: 100 (Very High)
How to Use the Calculator
Follow these steps to assess your vitamin deficiency risk:
- Enter Diet Diversity: Rate the variety of your diet (1–5, 1 = very limited, 5 = highly diverse).
- Enter Sunlight Exposure: Input daily sunlight exposure in minutes (0–120, ideal ~15–30).
- Enter Supplement Use: Rate frequency of supplement use (1–5, 1 = none, 5 = regular).
- Enter Lifestyle Factors: Rate lifestyle risk factors like stress or smoking (1–5, 1 = low risk, 5 = high risk).
- Calculate: Click “Calculate Vitamin Deficiency Risk Score” to see the result.
- Interpret Result: The result shows a 0–100 score with a rating (Low: 0–25, Moderate: 25–50, High: 50–75, Very High: 75–100). Low scores indicate higher risk. If you see “Please fill in all fields,” ensure all inputs are valid.
