Misclassification rates for current smokers misclassified as nonsmokers
OBJECTIVES: This paper provides misclassification rates for current cigarette smokers who report themselves as nonsmokers. Such rates are important in determining smoker misclassification bias in the estimation of relative risks in passive smoking studies. METHODS: True smoking status, either occasional or regular, was determined for individual current smokers in 3 existing studies of nonsmokers by inspecting the cotinine levels of body fluids. T…

Correlates of obesity in young black and white women
OBJECTIVES. Although differences in obesity between Blacks and Whites are well documented in adult women, less information is available on potential correlates of these differences, especially in young adults. METHODS. The association between behavioral and demographic factors and body size was assessed in 2801 Black and White women aged 18 to 30 years. RESULTS. Black women had significantly higher age-adjusted mean body mass index and subscapula…
Misclassification of smoking status in the Cardia study
BACKGROUND. Although widely used in epidemiological studies, self-report has been shown to underestimate the prevalence of cigarette smoking in some populations. METHODS. In the CARDIA study, self-report of cigarette smoking was validated against a biochemical marker of nicotine uptake, serum cotinine. RESULTS. The prevalence of smoking was slightly lower when defined by self-report (30.9%) than when defined by cotinine levels equal to or greater…
Racial differences in serum cotinine levels among smokers in the Coronary Artery Risk Development in (Young) Adults study
Cotinine was measured in the serum of nearly all 5,115 18-30 year old, Black and White, men and women participating in the Coronary Artery Risk Development in (Young) Adults Study, 30 percent of whom reported current cigarette smoking. Ninety-five percent of the reported smokers had serum cotinine levels indicative of smoking (greater than 13 ng/ml). The median cotinine level was higher in Black than White smokers (221 ng/ml versus 170 ng/ml; 95 …
