A new study conducted by researchers at Umea University in Sweden links a unpopular school life with health problems later in life including obesity and heart disease.
The researchers tracked the lives of nearly 900 16-year old students for nearly 27 years when they were 43 years old. The researchers found that those who were unpopular and isolated during their school days were at a greater risk of developing "metabolic syndrome" in their middle ages.
Metabolic syndrome is the name given to a combination of diseases such as obesity, diabetes and cardiovascular diseases.
"Our results support the notion that aspects of peer relationships are not only related to future health in the extreme end of the spectrum, e.g. restricted to those exposed to bullying or peer victimization, but that one's difficulties with peers are represented by a health gradient in adulthood", the researchers wrote in their report.
