Changes in the family structure and working world have increased the number of one-person households. According to population reports in the UK and USA, every third person in these countries lives alone. For this reason, a team of scientists lead by Dr Laura Pulkki-Råback, a researcher at the University of Helsinki, have studied whether this fact increases the risk of suffering depression. Their conclusions are that people living alone are 80% more likely to buy antidepressants than those living with other people.
They chose a sample of over 3,500 Finnish people, 1,695 men and 1,776 women, with an average age of 44.6 years. They checked their personal environment, and followed-up their use of antidepressant medication between 2000 and 2008. The results suggest ‘that the explanatory factors may be gender specific, with a lack of social support playing a greater role in men and socioeconomic disadvantages in women,’ they write in the study.
This paper shows a growing problem in developed countries; its authors even recognize that they would need more information to understand the extent of the matter. ‘This kind of study usually underestimates risk because the people who are at the most risk tend to be the people who are least likely to complete the follow up,’ says Dr Pulkki- Råback. ‘We were also not able to judge how common untreated depression was.’
