ABSTRACT
In the U.S. where Direct-to-Consumer Advertising (DTCA) of prescription medications is permitted, spending on DTCA has been accelerating. As a result, it has been an issue of intense public policy attention regarding whether DTCA is beneficial to the public by promoting a healthy lifestyle. Most of the literature concerning DTCA focuses on its impact on demand and empirical evidence regarding its impact on health-related behavior is scant. This study uses a database of DTCAs for high blood cholesterol, hypertension, diabetes, and overweight treatment medications that have appeared in nationally circulated U.S. consumer magazines during 2000 to 2004 and the Simmons National Consumer Survey in order to compute the level of individual advertising exposure and examines whether those who are exposed to DTCA are more likely to engage in regular exercise and diet control. The study finds evidence that for those with chronic conditions, greater exposure to DTCA leads to less exercise but more diet control. By therapeutic class level, exposure to DTCA leads to less exercise for those with hypertension and who are overweight, whereas those with high blood cholesterol are more likely to engage in regular exercise. Looking into differential responses by socioeconomic status, those with less education are more likely to engage in exercise after being exposed to DTCA. The results imply that the effects of DTCA vary by therapeutic class. In order to enhance the benefits of DTCA, it is important to closely monitor the messages in DTCA and require it to include messages that promote lifestyle change should it be a part of the treatment.
