Loneliness in adulthood follows a U-shaped pattern: it’s higher in younger and older adulthood, and lowest during middle adulthood, reports a new Northwestern Medicine study that examined nine longitudinal studies from around the world.
The study also identified several risk factors for heightened loneliness across the whole lifespan, including social isolation, sex, education and physical impairment.
“What was striking was how consistent the uptick in loneliness is in older adulthood,” said corresponding author Eileen Graham, associate professor of medical social sciences at Northwestern University Feinberg School of Medicine. “There’s a wealth of evidence that loneliness is related to poorer health, so we wanted to better understand who is lonely and why people are becoming lonelier as they age out of midlife so we can hopefully start finding ways to mitigate it.”
Lacking connection can increase the risk for premature death to levels comparable to smoking daily, according to the office of the U.S. Surgeon General, who one year ago called for action to address America’s loneliness epidemic. Graham said her findings underscore the need for targeted interventions to reduce social disparities throughout adulthood to hopefully reduce levels of loneliness, especially among older adults.
Perhaps one day general practitioners could assess levels of loneliness during regular wellness visits to help identify those who might be most at risk, Graham said.
