Risk factors for loneliness among older people in a Nordic regional context – a longitudinal study

The aim of this study was to examine the prevalence of loneliness among older people and to identify risk factors for loneliness in a Nordic regional context over a six-year period. Longitudinal data from the Gerontological Regional Database (GERDA) study of 4,269 older adults living in northern Sweden and western Finland, aged 65, 70, 75 and 80 at baseline in 2010, were analysed. Logistic regressions were used to analyse socio-demographic, social and health-related risk factors at baseline and changes in these for experiences of loneliness at follow-up. The results showed that most older adults (85%) did not experience loneliness at baseline or at follow-up in our study region. However, 3 per cent of the sample reported loneliness in both study years, indicating enduring and chronic loneliness. Analyses revealed that being widowed and becoming a widow/er as well as poor self-rated health at baseline and the onset of depression were risk factors for loneliness. Finally, the risk of loneliness was higher in older people living in Sweden. Further work is needed to explore changes and stability in loneliness as well as to increase our understanding of between-country differences in loneliness.
