Loss experiences in old age and their impact on the social network and depression- results of the Leipzig Longitudinal Study of the Aged (LEILA 75+)

Background: Loss experiences and bereavement are common among the oldest old. This study aims to investigate the effects of loss experiences and the social network type on depression in old age.

Methods: As part of the Leipzig Longitudinal Study of the Aged (LEILA 75+), a representative population-based cohort study, 783 persons aged 75+ years were assessed via standardized interviews including the Practitioner Assessment of Network Type Instrument (PANT) and the Center for Epidemiologic Studies-Depression Scale (CES-D). Effects of loss experiences and network type on depression were analysed cross-sectionally (baseline survey) using logistic regressions. Effects over time were analysed longitudinally (follow-up1 and follow-up2) using hybrid techniques.

Results: More than half of the elderly (57%) continuously lived in a restricted network. Only 12.1% lived in an integrated network. Although 30.9% had a change in their network, no significant association with loss experiences was found. Nevertheless, loss experiences (OR 7.56 (1.60-35.72)) and a restricted social network (OR 4.08 (1.52-10.95)) appeared to be the significant predictors of depression.

Limitations: Our study captures only a selected time window of the individual life and loss experience was only assessed at the time of the baseline survey.

Conclusion: Our findings revealed that elderly individuals, who experienced social loss or lived in restricted social networks, were more likely to develop depression compared to individuals who lived in integrated social networks or without loss experiences. The social integration of elderly individuals is an urgent issue that should be addressed in order to reduce depression in old age.
