, a first-of-its-kind study reveals.
In addition, insurance coverage/expense was the most common issue for people wishing to start the popular medications, known as GLP-1 receptor agonists. Side effects and drug shortages were among the reasons people stopped taking the medication.
Overall, people lost an average of 6% of their total body weight in almost 1 year of taking semaglutide, the class of drugs that includes Wegovy and Ozempic. When researchers compared people who had weight loss surgery with those who had not, total weight loss was almost identical: 5.8% in those who had surgery, vs 6.0% in those who had not.
People in this study lost a lower percentage of their total body weight, compared with people in clinical trials for the drugs, who tended to lose up to 15%, said lead investigator Pourya Medhati, MD, a postdoctoral research fellow at Brigham and Women’s Hospital in Boston.
These results suggest real-world weight loss results may be different than those in carefully controlled research studies. Dr. Medhati presented the findings at Digestive Disease Week® (DDW) 2024 in Washington.
Total weight loss was not significantly different between men and women in the surgery group. But in the nonsurgery group, women lost 6.4%, compared with 4.8% among men, a significant difference.
Dr. Medhati and Ali Tavakkoli, MD, chief of the Division of General and GI Surgery at Brigham and Women’s Hospital, used electronic health records to study 2491 adults prescribed semaglutide between 2018 and 2023 at Brigham and Women’s Hospital. Average age was 51, 74% were White, and 78% were women. A total of 13% had a history of weight loss surgery.
Costs, Side Effects, and Other Concerns
The investigators looked at issues around starting and staying on semaglutide in a subgroup of 500 patients. A total of 75 people never started the drug, for example. The majority, 72%, of this group said it was because of insurance coverage or the cost of the medication. Another 19% did not give a reason, and 9% said it was because of side effects.
People with higher body mass indexes and diabetes were less likely to start taking semaglutide, Dr. Medhati said.
Another 100 of the 500 patients started and then stopped semaglutide. Again, insurance coverage and cost were reasons, this time cited by 13%. About 36% stopped because of side effects; 21% pointed to a shortage of semaglutide; and 30% stopped for an unspecified reason.
“Our study highlights the importance of addressing insurance to ensure broader access,” Dr. Medhati said.
The 325 people who stayed on semaglutide lost an average of 8.5% of their total body weight at 50 weeks.
Access Remains Unequal
“These medications are incredibly powerful to treat obesity and weight-related disease both for people with a history of bariatric surgery and those without,” said session co-moderator Matthew Kroh, MD, vice chair of innovation and technology in the Department of General Surgery at Cleveland Clinic.
More equitable access to semaglutide and other GLP-1s is needed, he said. “Because the cost is so high and they’re not covered by most insurance plans at this point, people with better financial means have access to these medications,” while others may not.
Dr. Kroh said the findings may only apply to the patients, most of whom were female, White, and middle-aged. But he applauded the researchers for doing the study outside of a clinical trial. “Real-world data will help guide these decisions in the future,” he said.
