A lack of vitamin D in teenagers could leave them susceptible to developing heart disease and diabetes in later life, a study suggests. Research from the Johns Hopkins Bloomberg School of Public Health in the USA found that people aged 12-19 with low levels of vitamin D in their bodies had more than double the normal risk of high blood pressure. The study of 3,577 young people also found vitamin-deficient youngsters were 2.5 times more likely to have high blood sugar and four times more at risk of metabolic syndrome - including symptoms such as a fat waist, raised levels of triglyceride blood fats and low levels of "good" HDL cholesterol - all associated with heart disease and type 2 diabetes. A person's risk of developing diabetes and heart disease are increased by exhibiting three or more of these symptoms. Study leader Dr Jared Reis said: "We showed strong associations between low levels of vitamin D and higher risk of high blood pressure, hyperglycaemia (high blood sugar) and metabolic syndrome among adolescents, confirming the results of studies among adults."

Novo istraživanje pokazalo je da bi osobe s nedostatkom vitamina D mogle imati vrlo visok rizik od razvoja dijabetesa. Za to su istraživanje znanstvenici proučili podatke 903 zdrave odrasle osobe prosječne dobi 74 godine, bez naznaka predijabetesa ili dijabetesa. Ispitanicima su izmjerene razina vitamina D u krvi i glukoze u plazmi, te je proveden test oralne podnošljivosti glukoze (OGTT). Kroz nekoliko je godina kod 47 ispitanika otkriven dijabetes, a 337 ih je bilo u stanju predijabetesa. Znanstvenici su za zdravu razinu 25-hidroksi vitamina D u krvnoj plazmi odredili najmanje 30 ng/L. Otkrili su da se rizik za razvoj dijabetesa smanjuje s višom razinom vitamina D u krvi, što znači da osobe koje imaju nedostatak vitamina D, odnosno manje od 30 ng/L, imaju i mnogo veći rizik od razvoja dijabetesa. Potrebna su dodatna istraživanja kojima će se utvrditi mogu li povišene razine 25-hidroksi vitamina D u krvi spriječiti razvoj dijabetesa tipa 2, odnosno prijelaz iz predijabetesa u dijabetes.
