Low Levels of Vitamin D Linked to Development of High Blood Pressure

Reference: " Plasma 25-hydroxyvitamin D levels and risk of incident

hypertension among young women, " Forman JP, Curhan GC, EN,

Hypertension, 2008; 52(5): 828-32. (Address: Department of Medicine,

Renal Division and Channing Laboratory, Brigham and Women's Hospital,

Harvard Medical School, Boston, Massachussetts, USA. E-mail:

Summary: In a nested, case-control study involving 1,484 women between

the ages of 32 and 52 years who were not hypertensive at baseline,

plasma levels of 25(OH)D (indicative of vitamin D status) were found to

be lower among women who developed hypertension (25(OH)D=25.6 ng/mL), as

compared to controls who did not (27.3 ng/mL). Comparing quartiles of

plasma 25(OH)D levels, those in the lowest quartile of vitamin D status

had an adjusted odds ratio for incident hypertension of 1.66, compared

to women in the highest quartile of vitamin D status. Women with vitamin

D deficiency (<30 ng/mL) had a multivariable odds ratio of hypertension

of 1.47. The authors conclude, " Plasma 25(OH)D levels are inversely and

independently associated with the risk of developing hypertension. "
