Why Not Lonely? A Longitudinal Study of Factors Related to Loneliness and Non-Loneliness in Different Age Groups Among People in the Second Part of Life.

Age-related changes and losses may lead to loneliness. However, some people do not become lonelier, even after negative life events. This study examines the development of loneliness based on Norwegian panel data (N = 2,315), age 40-80 years at baseline, and the impacts of partnership and health measured in 2002, 2007, and 2017. We ask: How does loneliness develop over time, and who resists becoming lonely? In the total group, loneliness decreased from 2002 to 2007 and then leveled off. In the eldest age group, 70-80 years at baseline, loneliness increased but only in the last period, from 2007 to 2017. In all age groups and at all three times, those who were not lonely more often had a partner and were more often in good health compared to those who were lonely. Period effects, cohort, and age-related changes influencing the development in loneliness over time are discussed.
