What is the Role of the Pharmacist in Obesity Management?

Obesity rates have increased over the last two decades. Based on NHANES data, 68.8 % of US adults are classified as overweight or obese. Obesity increases the risk of diseases and can contribute to increased morbidity and mortality. This review examines studies published in which pharmacists have provided weight management services alone or in a team. The electronic databases OVID Medline, International Pharmaceutical Abstracts and EMBASE (1946-2014) were searched. Nine articles were identified in which pharmacists delivered a weight management service either alone or in a team, and eight studies collected outcomes. Six studies evaluated the participant’s weight loss or satisfaction with the service, and two studies evaluated weight loss associated with a meal-replacement program. The outcomes from these studies are limited and while positive, have failed to provide significant evidence of the impact of pharmacists providing these services. More randomized, controlled trials are needed to document weight management services.
