College of Public Health convenes panel on a growing public health crisis—social isolation Mary Cunningham Wed, 04/16/2025 - 16:10

When George Mason �鶹�� student Jawad H. first heard talk of reducing hours at the 24/7 campus dining hall, he saw more than a logistical issue—he saw a threat to a rare space where students could connect and stave off isolation. “I ran into a friend there at 11 p.m.,” he said during a recent College of Public Health panel. “By the time we finished talking, it was 3 a.m.”

As a member of the Student Government at the time, Jawad helped mobilize his peers to activate to preserve the dining hall’s hours—and defend its role as a social lifeline.

The theme and importance of intentional connection ran throughout “Stronger Together: The Impact of Social Ties on Public Health,” an April 9 panel at George Mason's Fairfax Campus hosted by the College of Public Health. This year, the annual National Public Health Week “Conversations and Connections” event explored a growing recognition that loneliness isn’t just a personal issue but a public health threat.

“Perhaps nothing has changed more profoundly in recent years than how we interact as human beings,” said Melissa Perry, dean of the College of Public Health, who moderated the panel. “We may check our phones hundreds of times a day, but go days without a real conversation. That disconnect has real health consequences.”

Two recent events helped elevate the issue: the collective isolation the world experienced during the COVID-19 pandemic, and a 2023 advisory from then-U.S. Surgeon General Vivek Murthy declaring loneliness “a national epidemic.” Murthy’s report links social isolation to a 29% increased risk of heart disease, a 32% increased risk of stroke, and a 50% increased risk of dementia for older adults. Loneliness, he warned, is as deadly as smoking 15 cigarettes a day.

“I’m glad that there’s a spotlight, because … loneliness has been sort of relegated to the purview of, this is an individual’s problem, as opposed to a systemic, structural problem,” said Rachel Wernicke, George Mason’s chief mental health officer. “We’re seeing more acceptance that there’s a collective responsibility for addressing this.”

Panelists focused on two groups especially vulnerable to isolation: older adults and young people.

George Mason alumna Mary Louise Pomeroy, PhD Health Service Research '22, a postdoctoral researcher at the Johns Hopkins Bloomberg School of Public Health, noted that 1 in 3 older adults report frequent loneliness, and around 25% are socially isolated. “What’s unique about older adults,” she said, “is the combination of high health needs with declining social support.”

For many in this population, technology—like smartphones, video chats, or even “social robots” in nursing homes—can be critical for easing isolation.

For young people, though, technology can sometimes have the opposite effect. “Their mood is just dropping,” said Wernicke, describing the impact of “passively scrolling” through social media. “But they’re not actually interacting—it’s the illusion of interaction.”

A 2022 national survey found that 60% of U.S. college students reported feeling “very lonely” in the past year.

Connections won’t emerge without deliberate intent, said LaToya Thomas, principal and founder of the urban planning consultancy Brick & Story, which focuses on community resilience. “We might need to do a little work, and that work is actually investing in our own inner curiosity about other humans,” she said. “And that curiosity might actually help pull someone out of a state of loneliness and isolation.”

Thomas pointed to tailgates before football games as one example of humans creating connections from inert spaces. “There is generally nothing exciting about these parking lots,” she said. But “people come and they bring chairs, they bring paraphernalia for their teams, they bring barbecue pits, they bring music. They literally create a space where there is no space. It’s really the intentionality of what we as social animals decide to do in terms of making spaces—as complex or simple as they can be—into something that is really dynamic.”

The Ozempic shortage is over. What now?

The Ozempic shortage is over. What now? Mary Cunningham Fri, 04/11/2025 - 16:00

After nearly three years of backorders and pharmacy scrambles, the high-demand weight-loss drugs Ozempic, Wegovy, and Mounjaro are finally back in full supply.

The FDA recently declared an end to the nationwide shortage of their active ingredients, semaglutide and tirzepatide. During the shortage, pharmacies were temporarily allowed to sell “compounded” versions—custom-mixed alternatives made from raw ingredients. But now that the FDA-approved brands are widely available, patients are facing new questions about access, safety, and ongoing care.

Martin Binks, chair of the Department of Nutrition and Food Studies at George Mason �鶹�� and a researcher and clinician with expertise in obesity, explains what this moment means for patients, providers, and public health.

Can people still get compounded versions of these drugs?

In most cases, no. The FDA rule is very clear. Now that the shortage is resolved, prescribers are only allowed to prescribe the safe and effective FDA-approved versions of these medicines—meaning pharmacies are prohibited from creating off-label compounded versions, even so-called “exact copies.” 

There will be rare exceptions when compounded versions are allowed. For example, if a patient has a specific medical need, such as an allergy, which can be resolved through minor changes in the drug’s formulation. 

If the FDA were to declare another shortage of these drugs, pharmacies would be allowed to sell compounded versions again. But this is very unlikely to happen given the huge investments companies like Eli Lilly and Novo Nordisk are making in these medications.

Why are the compounded versions no longer allowed? What are the risks for patients?

Compounded versions are not approved by the FDA, meaning they are not subject to testing for safety and efficacy. This creates a lot of risks when the products are used by large populations. Also, the FDA versions are subject to post-approval monitoring for any new safety issues, compounded versions are not.

While many compounding pharmacies did act ethically during the shortage, and within the scope of the FDA’s temporary rules, the public can’t always identify the difference between those and “bad actors” selling dangerous counterfeits.

Will “bad actors” continue to sell the non-FDA approved versions?

Given the nature of demand for these weight loss medications, it’s very likely dangerous entities will continue to sell unapproved compounded versions of these drugs, creating a risk to public health until or unless we can improve access to the FDA-approved medicines. A recent JAMA Network Open study showed that nearly half of all online pharmacies selling semaglutide were illegal operations, with some products containing dangerous impurities or excessive doses. Beyond the adverse effects a patient could directly suffer from this, it may also deter people from using the well-tested, well-controlled FDA versions of these drugs that could actually improve their health, essentially creating a double-edged threat to public health.

What’s the right way to use weight loss medications like semaglutide and tirzepatide?

These medications are intended to be used alongside overall healthy habits. Used appropriately, they can help manage appetite and metabolism for people with obesity, but they’re most effective when combined with lifestyle changes like healthy eating, physical activity, sleep, and stress management. It’s also essential that patients meet medical criteria for use.

How can patients protect themselves now?

Be cautious about where you get your medication. Don’t rely on online sources that promise cheap or no prescription access. Talk to a licensed health-care provider about safe, approved options. And keep in mind that bad actors may continue trying to sell counterfeit products even as legitimate compounding operations shut down.
