Determinants of ischemic heart disease in Seventh-day Adventists: a review

Most data from several countries shows Seventh-day Adventist men to have lower rates of ischemic heart disease (IHD) mortality. Similar data for women are somewhat conflicting. There is clear evidence that Adventists have lower serum total cholesterol and lower serum HDL cholesterol with the ratio of total cholesterol to HDL cholesterol being similar to that of non-Adventists. The risk relationships of this ratio may differ in different populations. There is a certain amount of evidence that vegetarians may have lower blood pressures but this is not clearly supported by data from Seventh-day Adventists. The lower risk for IHD in Adventist men, at least, is probably related to their dietary habits, nonsmoking status, possibly their better exercise habits, and greater social support.
