The report was issued after investigators interviewed at least 231 Haitian women who said that they were allegedly forced to perform sexual acts with UN peacekeepers in exchange for food and medicine.
"For rural women, hunger, lack of shelter, baby care items, medication and household items were frequently cited as the 'triggering need,'" the report said.
As for those women who lived in the city, they engaged in sexual relationships in exchange for "church shoes, cell phones, laptops and perfume, as well as money," according to the report, which is due to be released later this month.
It added that only seven of the interviewed victims "knew about the United Nations policy prohibiting sexual exploitation and abuse."
Earlier this year, prosecutors opened an investigation into claims that French soldiers raped children as young as nine during UN peacekeeping missions in the Central African Republic.
According to the Secretary-General's latest annual report on the issue, the total number of alleged cases of sexual abuse and exploitation by members of all UN peacekeeping missions stood at 51 in 2014, down from 66 the year before.
