A new study has found that men who have lost their partner to cancer and who are still single for four to five years after their loss, face a greater risk of developing mental illness as compared to those who have managed to find a new partner.
More than 22,000 people die of cancer in Sweden each year. It has been scientifically proven that relatives of the deceased are at greater risk of dying themselves or developing mental and physical illness, although studies have tended to focus on widows, and on the short-term risks.
Researchers at the University of Gothenburg's Sahlgrenska Academy carried out a unique long-term study of 691 Swedish men who lost their wives to cancer.
However, those who remained single were at far greater risk of developing depression, anxiety, sleep disorders and emotional blunting, and were also more likely to use sleeping pills and antidepressants.
"Previous studies have shown that people who lose their partner are at greater short-term poor mental health," Gunnar Steineck, who worked on the study, said.
"Our study is the first to show that the risk of poor mental health last for many years but, on the average, the risk is restricted to those who don't find a new partner.
"We need more research to understand the underlying mechanisms, but yes, emotional support from a new partner does probably help to process grief and protect against mental illness.
"But it could also be the case that those men who cope best with their loss are more likely to show an interest in finding a new partner," Steineck added.
