Research results that genes may be related to whether or not 'loneliness' is felt

Loneliness is greatly related to human health, as research shows that lonely people get colds and symptoms worsen . Under such circumstances, a new investigation result indicated that "how much a person feels lonely is determined partly by genes". This study has shown the possibility that the same gene may be involved in obesity and loneliness and contains important suggestions on the future treatment of the disease.

Your Feelings of Loneliness Could Be in Your Genes, New Study Reveals

In a new study, genetic mutation of 487,647 subjects registered in the UK Bio tank " UK Biobank " was investigated, and 15 genetic regions related to loneliness were identified. Although research has shown that loneliness is related to genes so far, this is the first study that actually identified gene regions.

The research team has also found evidence that obesity and loneliness are related, and one possibility is that one can promote the other. The same genes are considered to be related to obesity and loneliness, and it is possible that working together on both sides may be a better solution rather than solving either one.

John Perry of the University of Cambridge who studied "We tend to believe that loneliness is brought about by pure environmental and life experiences, but this research shows that genes are involved." "Always Although genes and the environment are mixed in complicated way, working on the problem of obesity at the group level can solve the problem of solitude ".

In this research, a questionnaire result was used in which subjects answered "loneliness" and "frequency of engagement with others". Survey methods using questionnaires are considered weak as a causal relationship proof method, but from the collected data "strong association" was seen. In addition, subjects were asked about their daily activities, as well as mutations in 13 genetic regions related to "whether to like pubs" and 6 gene regions related to "liking Jim" were confirmed . It also proved that there are mutations in 18 genetic regions related to "liking religion". We also know that there are duplications in areas such as depression, obesity and cardiovascular health, so it is possible that the risk of loneliness will increase as these become together.

Given the results of this research, if there are two people placed in a similar situation, one feels lonely but the other does not feel that there is a difference in genes It is conceivable.

However, researchers emphasize that genetic factors / non-genetic factors are deeply involved and that it can not be said that "there is a lonely gene" and "loneliness is completely inherited".
