Socialising 'increases longevity'

Socialising is good for you -- it increases longevity, say researchers.

A new study by Brigham Young University has found that individuals with adequate social relationships have a 50 per cent greater likelihood of survival compared to those with poor social relationships, 'PLoS Medicine' journal reported.

The magnitude of this effect is comparable with stopping smoking and exceeds many well-known risk factors for mortality such as obesity and physical inactivity, according to the researchers led by Julianne Holt-Lunstad.

In fact, they have based their findings on an analysis of 148 researches that included data from 308,849 individuals who were followed up for an average of 7.5 years.

Their analysis indicates that the overall effect remained consistent despite taking various factors, such as age, sex, initial health status, follow up period and cause of death, into account.

This result suggests that the association between social relationships and mortality may be general, therefore, efforts to reduce risk should not be isolated to certain groups, such as older people.

Efforts to reduce mortality via enhancing social relationship factors will require innovation but any future social relationship-based interventions represent a major opportunity to enhance both survival and quality of life, say the researchers.

They conclude that "physicians, health professionals, educators, and the public media take risk factors, such as smoking, diet, and exercise, seriously -- the data presented here make a compelling case for social relationship factors to be added to that list."
