Loneliness, Isolation Affect One Third of US Adults Over 50

TOPLINE:

About one third of US adults aged 50-80 years report feeling lonely and socially isolated, a new study of data from 2018-2024 shows. While the levels have returned to the pre-pandemic range, investigators say the findings suggest clinicians should screen for loneliness and isolation.

METHODOLOGY:

• Researchers conducted a nationally representative survey of US adults aged 50-80 years through the University of Michigan National Poll on Healthy Aging at six timepoints between 2018 and 2024.
• Data collection involved online surveys conducted using the Ipsos KnowledgePanel from 2018 to 2021, transitioning to online and phone surveys conducted using the National Opinion Research Center AmeriSpeak panel from 2022 to 2024.
• Sample sizes ranged between 2051 and 2576 respondents, with completion rates ranging from 61% to 78% across the survey periods.

TAKEAWAY:

• Loneliness rates among adults aged 50-80 years showed notable fluctuation, starting at 34% (95% CI, 31.7%-36.2%) in 2018, rising to 41% (95% CI, 39.1%-43.7%) in 2020, and returning to 33% (95% CI, 31.7%-35.1%) by 2024.
• Social isolation showed a similar pattern in the study group, starting at 27% (95% CI, 24.5%-28.8%) in 2018, peaking at 56% (95% CI, 53.4%-58.1%) in 2020, and declining to 29% (95% CI, 27.5%-30.9%) by 2024.
• Higher loneliness and social isolation rates were frequently reported among individuals who did not work, lived alone, had lower household incomes, and had self-reported fair and poor physical and mental health than those who reported excellent, very good, or good health.

IN PRACTICE:

The findings suggest that “much like routinely asking about diet and exercise, clinicians should consider screening older adults for loneliness and social isolation and connect them with appropriate resources,” the investigators wrote.

SOURCE:

The study was led by Preeti N. Malani, MD, MSJ, University of Michigan Medical School, Ann Arbor, Michigan. It was published online on December 9 in JAMA.

LIMITATIONS:

The study was limited by possible recall bias, reliance on self-reported data, lack of longitudinal results, and differences in survey timing, panels, and question framing across years. The findings may not have been applicable to excluded groups such as nursing home residents or individuals aged > 80 years, which limited their generalizability.

DISCLOSURES:

The study was supported by AARP and Michigan Medicine and the Department of Veterans Affairs, Veterans Health Administration, and Health Systems Research. One author reported receiving consulting fees and honoraria from various organizations. Details are provided in the original article.
