Serum 25-hydroxyvitamin D, parathyroid hormone, and their association with metabolic syndrome in Chinese.

Increasing evidence suggests that 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH) levels are associated with metabolic syndrome (MetS). In 2010, we explored the association of serum 25(OH)D and PTH levels with MetS in 1,390 Chinese participants, aged 20-83 years. Anthropometric phenotypes, blood pressure, and the incidence of MetS were evaluated.

Vitamin D, parathyroid hormone and their associations with hypertension in a Chinese population.

Background: Conflicting reports support or refute an association between vitamin D deficiency with high levels of parathyroid hormone (PTH) and raised blood pressure or hypertension.

Objective: To explore the associations of serum vitamin D and PTH levels with blood pressure and risk of hypertension in a Chinese population.

Methods: A population-based cross-sectional study was conducted among 1,420 Chinese participants, aged 20-83 years, in 2010.
