ABSTRACT
OBJECTIVES:
We explored potential effects of cadmium exposure on cardiovascular fitness measures, including gender and racial/ethnic differences.METHODS:
Data were from the 1999 to 2000 National Health and Nutrition Examination Survey (NHANES); 1963 participating subjects were included in our analysis. Volume of oxygen consumed at sub-maximum activity (VO(2) max) were recorded in a series of graded exercises; the goal was to elicit 75% of predetermined age-specific heart rates. Cadmium from urine samples was measured in the laboratory using standard methods. Multivariate linear regression analyses were performed to determine potential relationships.RESULTS:
Increased urinary cadmium concentrations were generally associated with decreased estimated VO(2) max values. Gender and racial/ethnic differences were also observed. Specifically, associations were statistically significant for white males and Mexican American females.CONCLUSION:
Inverse associations between urinary cadmium concentrations and estimated VO(2) max values were observed, including racial and gender differences. The implications of such gender and racial/ethnic differences on long-term cardiovascular health and health disparities of present public health concern warrant further investigation.
