CDC says this: "For a given standing height, African-American men, on the average, have longer legs than Caucasian men, and a correspondingly shorter trunk size; and therefore slightly smaller lungs (29,31,32,33) [CB for UW - these are footnote numbers] explaining most of the differences between predicted values for Caucasian and African-American men." cdc.gov But the real reason may be this: in 1978, OSHA decreed that the standard for exposure to cotton dust should be multiplied by .85% for blacks! In other words, there is a lower federal standard for pulmonary function tests for blacks who work around cotton dust than for whites. Mighty convenient if you happen to be in the cotton business! Especially in the Deep South! Just hire blacks and you won't have to keep the workplace as clean as you do for whites. Still the law, BTW, see section (h)(2)(iii): "A pulmonary function measurement, including a determination of forced vital capacity (FVC) and forced expiratory volume in one second (FEV<INF>1</INF>), the FEV<INF>1</INF>/FVC ratio, and the percentage that the measured values of FEV<INF>1</INF> and FVC differ from the predicted values, using the standard tables in Appendix C. These determinations shall be made for each employee before the employee enters the workplace on the first day of the work week, preceded by at least 35 hours of no exposure to cotton dust. The tests shall be repeated during the shift, no less than 4 and no more than 10 hours after the beginning of the work shift; and, in any event, no more than one hour after cessation of exposure. Such exposure shall be typical of the employee's usual workplace exposure. The predicted FEV<INF>1</INF> and FVC for blacks shall be multiplied by 0.85 to adjust for ethnic differences ."cdc.gov Cotton and blacks = politics? My guess is yes . . . . just cynical, I guess. And who was President in 1978? Jimmah Carter, that good ole' Georgia peanut farmer.
