For the study, her team analyzed data from a survey of more than 16,000 employees and their managers in the United States, Canada, Brazil, China, Denmark, France, Germany, Great Britain, Italy, Japan, Mexico, Spain, South Africa, South Korea and Turkey.
Nearly 3,000 of the workers said they were or had been depressed.
In general, managers in Asian countries tended to avoid employees with depression and were less likely to offer active support than managers in other parts of the world.
Managers in Japan and South Korea were least likely to offer help to employees with depression, while those in Mexico and South Africa were most likely to do so, the investigators found.
Managers in South Korea and China were the most likely to avoid talking about depression with workers. Managers in Canada, Denmark and Great Britain were least likely to avoid the topic, the study authors said.
In countries where managers tended to avoid dealing with depression, employees with depression took more days off from work than those in countries where managers were more likely to offer help and support, the findings showed.
The study also found that workers with higher levels of education took more time off for depression than those with less education.
Also, males aged 45 to 64 with medium to low levels of education were more likely than younger men to go into work despite depression, according to the report published online July 23 in BMJ Open.
