Sex education should be boosted for Shanghai's 3 million migrant workers, who are often deprived of basic services such as health care and schooling, a research institute says.
A survey found that more than 90 per cent of the migrants wanted to know more about the topic. Nearly half, 47 per cent, of sexually active women had been pregnant, with 90 per cent having abortions.
More than 1,000 unmarried migrant workers between the ages of 15 and 24 were questioned during the study by a Shanghai family planning organisation.
'Unmarried migrant workers' level of knowledge about sex is relatively low, although their attitudes toward sex are relatively tolerant and open,' it said.
Most of the migrants surveyed came from nearby rural areas to work in the city's construction and service industries or in factories.
Researchers said the survey was not the first of its kind in Shanghai but it was the most detailed.
