In Vancouver, British Columbia, a stack of colorful coupons sits next to the register at a local drugstore, offering 10 percent off on condoms. The two endeavors aim to block the spread of infectious diseases, especially AIDS, by making preventive tools available to people who might be reluctant to seek them out in clinics or doctors' offices. And two studies in the December issue of The American Journal of Public Health suggest that they are working. Researchers at Inserm, the French equivalent of the National Institutes of Health, and Johns Hopkins University looked at where drug users in Marseille got needles. The local government makes sterile needles available at drugstores, needle exchanges and vending machines. In the survey, conducted in 1997, questionnaires were handed out to 486 people getting needles at all three kinds of sites, and 343 were completed. The researchers found that people who used the vending machines tended to be younger drug users who were less likely than others to be infected with H.I.V. or hepatitis, making them an important group to catch before becoming infected. Needle exchanges drew in more experienced users, while pharmacies served older users, but neither tended to attract the youngest group with the highest risk. "I think younger people are more comfortable with vending machines," said David Vlahov, a professor at Johns Hopkins, who was an author of the study. "Why? Because they're not being preached at or to. They don't have to stand in line. There's more anonymity possible with this type of program. That's typically more attractive to young adults." Dr. Vlahov explained that when people started to inject drugs, they did not know how to do it themselves and tended to rely on others for supplies. "As they're developing the experience, the likelihood of getting a contaminated needle is high," he said. "The vending machines may be helpful in averting that. "Of course, the idea is to identify individuals early to get them not to use drugs. If they're not injecting, then we'd like to get in there and tell them injection is dangerous. For those who have started, we want them to stop. Those who won't or can't stop, well, we want to reduce the risk of transmission of these infections." The study's lead author, Dr. Yolande Obadia, director of the Regional Center for Disease Control of Southeastern France, said vending machines seemed to attract a "hidden part of the injection-drug-user population." The second study, in Vancouver, looked at ways to use marketing techniques to get people to buy condoms. While health organizations sometimes distribute condoms, the process can be expensive and sporadic. Researchers at the University of Manitoba used two different condom coupon strategies. In the first, a widespread distribution strategy, the researchers distributed coupons offering discounts to people at nightclubs, fitness centers and special events. In the second, more focused approach, the investigators made discount coupons available inside drugstores for use that day only. Researchers also observed the behavior of customers who received the coupons while they were in the drugstores. The use of the coupons was negligible in the more widespread distribution method. But in the more focused method, the rates of redemption were significantly higher than might otherwise be expected. The focused distribution was more effective, researchers said, because buyers had the occasion and limited time in which to make the purchase. "Making safety more available is a viable strategy," said Dr. Darren W. Dahl, the lead author and a professor of marketing in the Management School at the University of Manitoba. "Abstinence is the safest approach, but it's not for everyone. Those who don't choose that route to safety need other options." - --- MAP posted-by: Doc-Hawk
