From all women 67.3% where not officially married and their partners where not checked up as far as they where working outside Belarus. Only 8 women (8.4%) mentioned occasional sexual contacts. Unemployed women made of 52.6% of studied patients. Majority of employed women (64%) worked as unskilled workers. Others where academics—6.67%, medical professions—8.89%, students—8.89%, others—6.67%.
