In 2006, a US military study did a GOOD perspective study on MS that involved taking blood samples some 4-5 years prior to the start of their MS. In subjects under 20, high vitamin D levels offered a high rate of immunity form the disease Odds ratio = 0.09 which means perhaps 1/11th less likely to get it. A March 2008 good perspective study found a susceptible gene type with persistent Epstein Barr (mono) high titers had a wooping 9 times risk of getting MS later.
Vitamin D – nowhere to be had but vital

In general, high Vitamin D levels cut your MS chances in half but may be much more if less than 20 years old.
In a Norwegian study, adolescents age 16-20 cut their risk in half of getting MS if they had increased outdoor activity or ate fish 3 times/week (high in Vitamin D).
Outdoor activities and diet in childhood and adolescence relate to MS risk above the Arctic Circle

There is very little Vit D from sunlight from October – March in Canada. A Calgary study found 100% of people were deficient some time of the year if not on replacement. The 400 units/day recommended will not give appreciable levels. 1,000 – 2,000 u/ day would be needed for that and is perfectly safe.
Gene type combined with persistent mono bad news:

Integrating risk factors: HLA-DRB1*1501 and Epstein-Barr virus in multiple sclerosis.

HLA-DR15 by itself did not increase risk, but this gene type plus high antibody titers (anti-EBNA-1) were related to a 9 fold risk of MS.
Comment – adolescents can be checked for Vit D through a 25-OH-Vit D blood level. Almost all patients I have checked are in the low range. I have a feeling that most chronic diseases are adolescent.:
Osteoporosis – the most bone you will ever have is at 21 – not got much then- well, it’s all down hill from there.
Lung disease – nicotine is so addicting for adolescence that if they find it relaxing on the first cigarette, they are often addicted thereafter.
Obesity and inadequate exercise are adolescent habits. I see in the US obesity in children is now being considered an epidemic. This way of life leads to metabolic disease, heart disease, hypertension, and diabetes and downhill from there.
