LINK BETWEEN LONELINESS AND MENTAL DISORDER

When the scientists delved deeper into the relationship between CMDs and living alone, they found that loneliness explained 84% of the association.

Earlier studies had shown that loneliness is linked with depression and anxiety. Others still had investigated whether loneliness might 
increase mortality risk.
During what some experts call a "loneliness epidemic," this finding is particularly important. Similarly, because ill mental health is a growing concern, understanding the risk factors associated with CMDs might help turn the tide.
Of course, not everyone who lives alone is lonely. However, for those who are, interventions to tackle loneliness are available. These may include talking therapies, social care provisions, and animal-based interventions.
The next and most challenging step is to find ways to ensure that people in need get access to these tools.
The researchers acknowledge certain limitations to the study. For instance, this was a cross-sectional study, meaning that it looked at a snapshot of people at one point in time. The authors call for longitudinal studies to ascertain how this relationship might play out over time.
As with any study of this nature, assessing cause and effect is not possible: Did a person develop a CMD because they lived alone, or did they develop a CMD and then decide to live alone?
Or, perhaps, someone with a predisposition for CMDs is more likely to want to live alone. As ever, scientists will need to carry out more work to fill in the gaps.
Earlier findings back up these results, but the new findings also go a few steps further; they show that the relationship between mental health and living alone is stable across time, that the link is not restricted to older adults, and that loneliness plays a pivotal role.
