Metabolic syndrome and salt sensitivity of blood pressure in non-diabetic people in China: a dietary intervention study.

The article presents a dietary intervention study that examined the association between metabolic syndrome and the salt sensitivity of blood pressure. The study involved 1906 Chinese participants without diabetes, aged 16 years or more, who were selected to receive a low-sodium diet followed by a high-sodium diet. The presence of three or more of the following conditions constituted metabolic syndrome: abdominal obesity, raised blood pressure, high triglyceride concentration, low high density lipoprotein (HDL) cholesterol, or high glucose. Metabolic syndrome was found to enhance blood pressure response to sodium intake. The authors explain that reducing sodium intake could be important in reducing blood pressure in patients with multiple risk factors for metabolic syndrome.
