Weight Loss Product Use Millions of people feel a desire to lose weight or have a medical need to do so. Weight loss is found to be very difficult and compromising to a lifestyle for most; therefore, many of those attempting to diet seek out over-the-counter products that facilitate weight loss. Widespread use of nonprescription weight loss products, including phenylpropanolamine (PPA) and ephedra, have raised significant safety issues. Study Design These safety concerns led researchers to determine more precisely the prevalence of the use of nonprescription weight-loss products. Investigators conducted random telephone interviews to evaluate usage in relation to demographics, prescription diet pill usage, diabetic status, and lifestyle decisions. Results Nonprescription weight-loss-product usage was reported in 1:14 (7%) of all people interviewed. Two percent of the study population indicated that they used PPA and 1% used ephedra. The highest percentage (28.4%) of users was young women who are obese. But even 7.9% of women of normal weight reported that they use OTC weight-loss products. Among prescription weight loss users, 33.8% also used nonprescription products. More users than nonusers were considered to by physically active, but there was no difference in general eating habits, defined by consumption of fruits and vegetables. Conclusion Due to the overall increase in incidence of obesity, the use of prescription and nonprescription weight-loss products is expected to rise proportionately. It is important that physicians ask their patients if they are taking these products and advise about the appropriate precautions. For more information, refer to: JAMA 2001;286:930-935. Return to Top
