Methodology Used in Vitamin Deficiency Risk Calculator

The calculator uses a weighted scoring system:

1. Risk Score per Vitamin: \\( S_v = W_d \cdot D + W_s \cdot S + W_a \cdot A + W_u \cdot U \\)

2. Risk Level: Low (\\( S_v \leq 3 \\)), Moderate (3 < \\( S_v \leq 6 \\)), High (\\( S_v > 6 \\))

Where:

\\( D \\): Diet score (vegan: high for B12; omnivore: lower)
\\( S \\): Sunlight score (low exposure: high for D)
\\( A \\): Age score (51+: higher risk)
\\( U \\): Supplement use (no: higher risk)
\\( W \\): Weights specific to each vitamin

Assesses risk based on dietary and lifestyle factors.

Example Calculation

Sample Input

Diet = Vegan, Sunlight = 5 hours/week, Age = 51+, Supplements = No

Step 1: Vitamin B12: \\( S_{B12} = 3_{\text{vegan}} + 1_{\text{sunlight}} + 2_{\text{age}} + 2_{\text{no supp}} = 8 \\) (High)

Step 2: Vitamin D: \\( S_D = 1_{\text{vegan}} + 3_{\text{low sunlight}} + 2_{\text{age}} + 2_{\text{no supp}} = 8 \\) (High)

Result: B12 = High, D = High, A/C/E = Low/Moderate.
