Elderly people who are socially isolated are at an increased risk of death regardless of whether they believe they are lonely or not.
Researchers at University College London conducted the study among 6,500 men and women over the age of 52 years and found that those who are cut off from friends and families were 26 percent more likely to die over a seven year period compared to those who were not isolated. The researchers also found that the risk increased even if the participants did not feel that they were lonely.

It would suggest that those practical aspects are quite important for older people's survival. There's been such an increase in people living alone. In the last 15 years, the number of 55 to 64-year-olds living alone has increased by 50%. And it might be that people in those circumstances aren't looking after themselves so well", lead researcher Prof Andrew Steptoe said.
The study has been published in the Proceedings of the National Academy of Sciences.
