The death of a significant other is seen as a major life disruption. What are the consequences when such a loss occurs during advanced old age? Based on observation of an octogenarian cohort over a period of five years (1994-1999), this study investigates the impact of losing a significant other (close relative or friend) on the health of elders and on their family and social life. The bereaved are compared with two control groups: one declaring no significant change in their life and the other reporting a loss unrelated to bereavement. Results show that the death of a significant other has no impact on the measures of functional and physical health, nor is it a factor of isolation. However, the loss of a close relative is associated with more depressive symptoms while that of a relative or friend is related to the survivor's feeling of loneliness.
