A meta-analysis of more than 2 dozen studies published in the journal BMC Psychiatry finds that insomnia carries more than double the risk of depression, reports Psychiatry Advisor.
“The current meta-analysis showed that the increased risk was more pronounced for participants from the United States than for European participants,” reported Liqing Li, of the Tongji Medical College of the Huazhong University of Science and Technology in Wuhan, China, and colleagues. “In order to make the finding [generalizable] to other populations, more studies are warranted to be conducted in other populations from Asia, Africa, and South America.”
