A new study following the growing percentage of iron levels among people living in heavily industrialized nations and the potential risk of cardiovascular disease among men with high iron levels, has shown that women with high iron levels could also find themselves at risk for cardiovascular disease.
The study carried out by researchers from the Emory University involved a total of 3,349 women, out of which, 1,179 were non-Hispanic white, 1,094 were non-Hispanic black, and 1,076 were Mexican-American. Information from the National Health and Nutrition Examination Survey was used as a guide by researchers to examine iron levels and CVD risk factors such as body mass index, total cholesterol, triacylglycerol, HDL cholesterol, plasma glucose, and blood pressure.
Iron levels were associated to CVD risk factors among non-Hispanic black women and, especially, Mexican-American women, according to the study. The strongest association was found for Mexican-American women whose higher iron levels were linked with higher levels of body mass index, total cholesterol, triacylglycerol, glucose and diastolic blood pressure.The researchers suggested that, on the whole, CVD risk factors, especially those relating to glucose and lipid metabolism, are definitely linked with iron status in women.
