VitaminDWiki Summary

Analysis of ~1000 middle aged people in France
Unfortunately there are a significant number of false positives
That is, scoring system indicates deficiency (< 20 ng) when it did not exist
   Note: Many believe that >30 ng, > 40 ng, or > 50 ng is needed

Points reasons
1.5 female sex, overweight, low physical activity, winter season
moderate sun exposure, very fair or dark skin
2 latitude ≥48°N and spring season
2.5obesity and late winter
3 low sun exposure

Total points< 20 ng
7 70%
>980%


Their simple system does not consider the following
Low magnesium, smoking, cola drinks, low cholesterol in diet
health problems which consume Vitamin D
Excessive UVA (thru windows, late afternoont)
Poor gut, DDT, Excessive Vitamin A, Gall bladder removed
Take drug which consumes of blocks Vitamin D
Age - reduced vitamin D from gut and from skin, reduced stomach acid
Pregnancy, Excessive clothing, Poor Kidney. Low Omega-3
Roundup in food, Night shift. Born in winter. Genes

Vitamin D is essential regarding several health outcomes. Prevention of insufficiency (25-hydroxyvitamin D concentration ≤20 ng/mL) generally entails blood testing and/or supplementation, strategies that should target at-risk individuals because blood testing is costly, and unwarranted supplementation could result in vitamin D overload with unknown long-term consequences.Our objective was to develop a simple score (Vitamin D Insufficiency Prediction score, VDIP) for identifying adults at risk of vitamin D insufficiency.Subjects were 1557 non-vitamin D-supplemented middle-aged adults from the SU.VI.MAX cohort. Scoring points corresponded to the rounded odds ratio for each individual-level characteristic associated with vitamin D insufficiency in a multivariable logistic regression model. Receiver operating characteristic curve (area under curve), sensitivity, specificity, and positive and negative predictive values were computed. External validation was performed in an independent cohort (NutriNet-Santé, N = 781).For female sex, overweight, low physical activity, winter season, moderate sun exposure, and very fair or dark skin 1.5 points were attributed; 2 points for latitude ≥48°N and spring season; 2.5 points for obesity and late winter; 3 points for low sun exposure. Points were then summed up for each participant. The VDIP score had an AUC = 0.70 ± 0.01 (validation: 0.67 ± 0.02). With a score of 7 or more, 70% of the participants were vitamin D-insufficient (80% in those with a score ≥9), sensitivity/specificity were 0.67/0.63, and positive and negative predictive values were 0.70/0.59. The VDIP score performed well in identifying middle-aged adults at risk of vitamin D insufficiency (score ≥7, moderate risk; score≥9, high risk), using only simple individual-level characteristics easily assessable in day-to-day clinical practice. Implementation of this simple and costless score could thus obviate unwarranted supplementation and/or blood testing.
