People who experience moves before the age of 15 are over 40% more likely to be diagnosed (诊断) with depression in later life, a new study has shown.
The study was carried out by researchers from Aarhus University (Denmark), the University of Plymouth (UK) and the University of Manchester (UK). It analysed all residential locations of almost 1.1 million people born in Denmark between 1981 and 2001 and who stayed in the country during the first 15 years of their lives. It then tracked those same individuals into adulthood, and found at least 35,000 of those still living within Denmark had later received a medical diagnosis of depression.
As part of a detailed analysis, the study supported existing evidence by showing that individuals who live in income deprived (不足的) neighbourhoods during childhood are more likely — by a factor of around 10% — to develop depression in adulthood. Does this mean that depression is solely related to low income? The study, for the first time, showed that experiences of moving during childhood — whether between or within poor or rich neighbourhoods — are also associated with significantly higher rates of depression in adulthood.
Specifically, children who move once between ages 10 and 15 are 41% more likely to be diagnosed with depression than those who don’t move. And if a child moves twice or more between the ages of 10 and 15, the risk rises to around 61%. This is a stronger effect than growing up in a poor neighbourhood. It has led researchers behind the study to suggest a settled home environment — in terms of location — during childhood may be one way of protecting against future mental health issues.
And while its focus was on a significant proportion of the Danish population, the study authors say they would expect to find similar outcomes across many parts of the world.
