Loneliness trajectories and predictors in Spain: Results from the Spanish longitudinal study on aging and health (Edad con Salud).

BACKGROUND

In recent years, loneliness has been recognized as a public health problem, exacerbated by the COVID-19 pandemic. This study aims to identify groups of people with different trajectories of loneliness, and to explore potential determinants (sociodemographic, social, psychological, and health-related) associated with these trajectories.

METHODS

In this 12-year longitudinal study, we analyzed data on 4537 Spanish adults from a nationwide representative survey. A growth mixture modeling approach was used to identify different loneliness trajectories and logistic regressions to explore the determinants of these trajectories.

RESULTS

Two trajectory classes were identified: low-stable (87.86 %) and high-fluctuating (12.14 %). Marital status, living status, migration, social isolation, depression, suicidal ideation, and cognitive complaints were identified as significant determinants of belonging to the high-fluctuating trajectory. Conversely, social support, social trust, and life satisfaction were protective factors for this trajectory.

CONCLUSION

This study revealed the presence of diverse courses of loneliness (each showing some distinctive characteristics from the other), outlining some relevant implications for the assessment, prevention, and management of loneliness.
