A study has found that the retirement of husbands could increase their wives' chances of suffering depression by up to about 70 percent in Korea. 
 
Researcher Kang Mo-yeol at Seoul National University College of Medicine presented the results of the study after analyzing some six-thousand men and women over the age of 45 enrolled in the Korean Longitudinal Study of Aging.
 
The SNU Department of Preventive Medicine said in the report that women whose husbands voluntarily retire are 70 percent more likely to develop depression than those with working husbands.
 
Korean women whose husbands retired involuntarily showed 29 percent higher chances of suffering depression. 
 
The findings were listed in the latest edition of Comprehensive Psychiatry.
