Metabolic syndrome is a group of risk factors that occur together and increase your risk of heart disease, stroke, and type 2 diabetes. Having at least three of the following risk factors could indicate metabolic syndrome: high blood pressure, high blood sugar, high triglyceride levels, low HDL cholesterol levels, and excess body fat around the waist. Age and estrogen loss have been strongly associated with metabolic syndrome, which affects approximately 30-60% of postmenopausal women worldwide.

This month (June 2019), results from a study assessing the association between vitamin D and estrogen with metabolic syndrome were published. This study included 616 postmenopausal women aged 49-86 years residing in China.

What were the findings of the study?

Both vitamin D and estrogen levels were independently associated with risk of metabolic syndrome. Specifically, women with vitamin D levels less than 20 ng/ml (50 nmol/L) had more than two times the risk compared to women with levels at or above 30 ng/ml (75 nmol/L) (P=0.02). Women with the lowest estrogen levels (less than 10 pg/mL) had roughly 1.7 times the risk compared to women with the highest estrogen levels (16 pg/mL or above) (P=0.04).

The research team also found that among women with vitamin D levels less than 20 ng/ml, those with the lowest estrogen levels had almost 3 ½ times higher risk compared to women with the highest estrogen levels (P=0.006). However, there was no significant association among women with vitamin D levels at or above 20 ng/ml. This suggests a synergistic role between estrogen and vitamin D such that those with low levels of both vitamin D and estrogen are particularly at risk for metabolic syndrome.
