SA Perspectives

I n October, California voters did something that will have long-term ramifications for their state. No, we’re not talking about the election of actor Arnold
Schwarzenegger, but the rejection of Proposition 54, which would have voided requirements for government-affiliated programs to record the race of participants. Medical groups and physicians had claimed that the measure would have blocked doctors from tracking and treating diseases that afflict various racial groups differently. C. Everett Koop, former U.S. surgeon general, even described the vote as a “life-anddeath decision” in a television ad.
The article by Michael J.
Bamshad and Steve E. Olson in this month’s issue [“Does Race
Exist?” on page 78] calls into question Koop’s dire assertion.
Commonly used racial and ethIS RACE linked nic categories (such as “Africanto health?
American,” “white” and “Hispanic”)
