29 Aug 2017 --- For those with schizophrenia and bipolar disorder, there is an increased prevalence of obesity and its related diseases such as type 2 diabetes and cardiovascular disease. Because of a number of factors, including obesity, the lifespan for those with schizophrenia is 20 years shorter than the general population. It is also 10 years shorter for those with bipolar disorder. But in a first-of-its-kind study, researchers from Florida Atlantic University have shown that expanding waistlines and the way body fat is distributed are largely to blame.
