Most people at some point feel a temporary sense of isolation and loneliness, but
others suffer a deeper, more lasting mood that affects their mental and physical health.
In a new report, researchers in the at the 深夜看片鈥檚鈥(COPH) address loneliness and social isolation and potential solutions to an elusive
and often misunderstood problem.
鈥淧eople think about epidemics more as diseases or something with a diagnosis or that鈥檚
more visible,鈥欌 said , interim chair, and distinguished university health professor. 鈥淭here鈥檚 not a 鈥榙iagnosis鈥 per se
for loneliness or social isolation, but the risks they create are real and important
for society to consider.鈥欌
Liller and her team outlined their work in 鈥,鈥 published in the Journal of Health Advocacy.

They discuss how loneliness and social isolation are at a concerning level in the
United States, with about half the population 鈥 roughly 160 million people 鈭 reporting
loneliness as constant in their lives, according a 2023 report by the U.S. Department
of Health and Human Services,鈥疧ffice of the Surgeon General. It said the health consequences
can be equivalent to smoking 15 cigarettes per day or having alcohol use disorder,
leading to both short and long-term adverse effects on a person鈥檚 health. Outcomes
range from poor sleep quality to suicidal thoughts.
鈥淎ccording to various literature, being lonely and isolated can trigger chronic stress
which can lead to inflammation and a weakened immune system,鈥欌 Liller said of other
symptoms. 鈥淚t can also lead to cognitive decline and mental health issues, including
depression.鈥欌
Florida ranks high in part because of the large elderly population, with an estimated
11 million people dealing with some form of isolation and loneliness. However, younger
individuals are now at an increased risk as well, a rate exacerbated during and after
the COVID-19 pandemic. When looking at other underlying causes, issues such as identity
formation, life transitions, moving away from family and friends to attend college,
have been specifically related to loneliness among young people, according to Liller鈥檚
report.
However, loneliness and social isolation are not the same thing. Loneliness encompasses
鈥渁 feeling or subjective distressing experience that results from perceived isolation
or inadequate connections鈥欌 according to the COPH authors. Social isolation is measured
in terms of having few social relationships and roles, or group memberships, and infrequent
interactions.

In preparing the paper, Liller worked with colleagues in the Activist Lab, which she
founded in 2018 as a platform to prepare students as public health leaders. Each
year, the lab conducts more than 70 education, research, and outreach projects regarding
public health. Contributing to the paper were COPH undergraduate student Manisha Katwal,
graduate student Hannah Harburg, and Gabriella Hinks, a recent COPH alumna..
To address isolation and loneliness, in 2023 the Activist Lab partnered with the Florida
Public Health Association to develop a statewide task force focused on identifying
and addressing these two growing issues across the state. The collaboration led to
a community resource guide, advocacy tools, educational programs and actions to better
assess the epidemic at the local and state levels. The task force met monthly to discuss
the strategies of the different agencies involved such as connecting with seniors
in communities with weekly phone calls and information about resources, health fairs,
working with veterans on health care issues including suicide prevention and educational
portals.
One group that works with Activist Lab is Health Buddies, part of Seniors in Service, a non-profit established in 1984 to assist older and socially isolated adults. It connects trained volunteers, primarily 深夜看片 students, with people in need through regular phone companionship, resource support, and encouragement to age safely and independently.
Through its partnership with USF, Seniors in Service makes use of research expertise
with hands-on experience serving the community, said Health Buddies program manager
Aria Garling.
鈥淭his ensures that we are not only evidence-based but responsive to the real needs
of older adults in Florida, helping reduce unnecessary emergency room visits and hospital
readmissions,鈥欌 she said.
In developing the journal paper, the researchers collected baseline information from
about 4,000 respondents that could guide future planning and prevention efforts.
鈥淲orking on this project profoundly shaped my understanding of public health, not
only as a field of study but as a lived and systemic reality,鈥欌 Katwal said. 鈥淏efore
engaging in this work, I understood loneliness and social isolation primarily as emotional
experiences. Through this project, I learned that they are deeply rooted public health
concerns with measurable health consequences, social implications, and structural
determinants.鈥欌
She added that social isolation isn鈥檛 simply about being alone, but an experience
influenced by social systems, community infrastructure, economic pressures, technology
use, and the environment.
鈥淔actors such as transportation access, urban design, workplace culture, and digital
communication all shape opportunities for meaningful connection,鈥欌 she said. 鈥淚 began
to see loneliness not as an individual weakness, but as a systemic outcome of how
society is structured.鈥欌
