BACKGROUND Epidemiologic studies have shown increased risks of lung cancer among adults with low blood levels of selenium, although evidence is inconsistent. In the United States, the incidence of lung cancer is higher and mean serum selenium levels lower among Blacks than Whites, but prior studies have not assessed the selenium-lung cancer association among Blacks. METHODS From the prospecti...
According to the third National Health and Nutrition Examination Survey, African Americans have a lower prevalence of metabolic syndrome than do Whites. Recent reports in Blacks in other regions have confirmed these observations, but the rates vary. This lower rate of metabolic syndrome in Blacks can be partly ascribed to the lower prevalent rates of some major components of metabolic syndrome,...
A total of 94,7463 patients with lung cancer were identifi ed between 1973 and 2010 ( Tables 1 , 2 ). Th e proportion of SCLC to total lung cancers decreased over the years along with the sex gap; the ratio of men to women decreased from 2.69:1 in 1973 to 1:1 in 2010. Th e fi ndings were consistent between both black and white patients. Th e incidence of SCLC compared with all lung cancer was c...
Several reports indicate that erythrocytes (RBCs) from blacks and men have higher sodium concentrations than those from whites and women. One possible mechanism to explain this finding is a difference in the activity of Na+-K+-ATPase. To explore this possibility, we have studied the Na+ and K+ kinetics of RBC Na+-K+-ATPase and RBC Na+ and K+ concentrations in 37 normotensive blacks and whites, ...
OBJECTIVE To validate a 204-item quantitative FFQ for measurement of nutrient intake in the Adventist Health Study-2 (AHS-2). DESIGN Calibration study participants were randomly selected from the AHS-2 cohort by church, and then subject-within-church. Each participant provided two sets of three weighted 24 h dietary recalls and a 204-item FFQ. Race-specific correlation coefficients (r), corre...
Seventy-one white and 33 black patients with essential hypertension were studied while on a high sodium intake of 350 mmol/d for 5 days and low sodium intake of 10 mmol/d for 5 days. The fall in blood pressure on changing from the high sodium to the low sodium diet was 17/6 mm Hg in whites and 22/10 mm Hg in blacks. Compared with whites, black patients had a 7-mm Hg greater fall (P<0.05) in sys...
O]ne substantial factor [for the growing inequality of income and wealth] seems to be unstated understanding by the mass of whites that they will accept large disparities in economic opportunity to other whites as long as they have a priority over blacks and other people of color for access to those opportunities. ... [There are] several instances in American history when whites have acquisced ...
