Loneliness Trajectories and Chronic Loneliness Around the World

Area of Science:

• Gerontology
• Public Health
• Sociology

Background:

• Loneliness is a growing public health concern among middle and older adults.
• Cross-national research is needed to understand variations in loneliness and its risk factors.

Purpose of the Study:

• To examine cross-national differences in loneliness trajectories.
• To investigate the association between social risk factors and chronic loneliness in adults aged 50+.
• To compare how these associations vary across different countries.

Main Methods:

• Longitudinal data from 20 countries representing 47% of the global population aged 50+.
• Assessment of loneliness trajectories (chronic, transitory, no loneliness).
• Analysis of social risk factors: living alone, widowhood, divorce, no grandchildren, chronic conditions, never working.

Main Results:

• Significant cross-national variation in chronic loneliness prevalence (4% in Denmark to 15% in Greece).
• Living alone consistently associated with higher chronic loneliness risk (average 8% increase).
• Never working and chronic conditions also linked to increased chronic loneliness in over a third of countries.

Conclusions:

• Targeted policies and interventions for middle-aged and older adults are crucial.
• Interventions should focus on individuals living alone, with limited work histories, or chronic conditions.
• Addressing social determinants of loneliness is key to mitigating public health challenges.
