Abstract
Despite the role vitamin E may have in protecting against various chronic conditions, little is known about vitamin E status in the US population. Using data from the Third National Health and Nutrition Examination Survey (1988–1994), the authors examined the distribution and correlates of serum α-tocopherol among 16, 295 US adults aged 18 or more years. The mean concentration of α-tocopherol was 26.8 jimol/liter (geometric mean, 25.0 nmol/liter). The 25th, 50th, and 75th percentiles were 19.6, 24.1, and 30.4 p/nol/liter, respectively. The mean a-tocopherol/cholesterol ratio was 5.1 (geometric mean, 4.9); the 25th, 50th, and 75th percentiles were 4.1, 4.7, and 5.5 (10−3), respectively. About 27% of the US population had a low α-tocopherol concentration (Am J Epidemiol 1999; 150: 290-300.Keywords
