Abstract
In view of the growing evidence for leukocyte count as an important cardiovascular risk factor, data from the first National Health and Nutrition Examination Survey (NHANES I) were examined to determine the association of leukocyte count with a number of other cardiovascular risk factors. Complete data were available for 5586 persons. Multiple linear regression analyses revealed hemoglobin concentration and height in white male nonsmokers and hemoglobin, cigarettes/day, and pulse rate in white male smokers were associated with leukocyte count. In white female nonsmokers, age, pulse rate, systolic blood pressure, height, and uric acid concentration were associated with leukocyte count. In white female smokers, hemoglobin, cigarettes/day, pulse rate, and height were associated with leukocyte count. However, associated variables explained only 8% of the variation in leukocyte count. Other measured risk factors were not associated with leukocyte count. Future analyses of leukocyte count and cardiovascular disease should control for hemoglobin concentration and pulse rate in addition to smoking, blood pressure, and cholesterol.
