Four-Year Loneliness Trajectory and Its Predictors in Older Adults

Area of Science:

• Gerontology
• Psychology
• Public Health

Background:

• Loneliness is a significant, modifiable risk factor for health decline in older adults.
• Understanding the dynamics of loneliness over time is crucial for targeted interventions.

Purpose of the Study:

• To explore the four-year trajectory of loneliness in older adults.
• To identify between-person and within-person predictors of loneliness changes.

Main Methods:

• Growth curve modeling was used to analyze annual data from 128 older adults (mean age 77.91) from 2017-2020.
• Participants resided in independent-living or retirement communities.

Main Results:

• A quadratic model indicated loneliness decreased then increased over four years.
• Baseline social relationships and health (especially depressive symptoms) predicted loneliness levels.
• Increased depressive symptoms and decreased physical functioning were linked to rising loneliness; the COVID-19 pandemic impacted this trajectory.

Conclusions:

• Older adults' loneliness follows a nonlinear, U-shaped path with individual variations.
• Social connections and health status, particularly depressive symptoms, are critical factors influencing loneliness.
• Interventions should support socially isolated or health-declining older adults to promote healthy longevity.
