Metabolic syndrome increases the risk of developing type 2 diabetes and cardiovascular disease. One is five people are affected, and that rate increases as people age. Salt reduction in people with metabolic syndrome may help play a role in early intervention, and more effective treatment.
Now a study from China examines the connection between metabolic syndrome and blood pressure sensitivity. Metabolic syndrome was defined as the presence of three or more of: abdominal obesity, raised blood pressure, high triglyceride concentration, low HDL cholesterol, or high glucose.
Nearly 2000 Chinese volunteers, who did not have type 1 or type 2 diabetes, were put diets with varying levels of sodium. Compared with those with no risk factors, participants with four or five risk factors for metabolic syndrome had a three-and-a-half times higher risk of high salt-sensitivity during the low sodium phase and a three-fold higher risk of high salt-sensitivity during the high-sodium phase.
"Metabolic syndrome enhances blood pressure response to sodium intake," writes Dr. Jing Chenin, in an online article soon to be published in The Lancet. "Reduction in sodium intake could be an especially important component in reducing blood pressure in patients with multiple risk factors for metabolic syndrome."
