Industrial workers or factory workers, especially migrant workers, have been found to be vulnerable populations at risk of sexually transmitted infections (STIs). However, there has been a gap in literature regarding health behaviors of migrant factory workers. We conducted a cross-sectional study among 230 factory workers in Hanoi and Bac Ninh cities in Northern Vietnam from July to September 2018 to identify sexual risk practices and related factors among migrant and nonmigrant factory workers. Information collected regarding sexual behavior included the number of sexual partners in the previous 12 months and whether they used condoms in their last sexual intercourse. Two-thirds of participants reported having no sexual activity in the last 12 months, and there was a low percentage of participants using condoms in their last sexual intercourse. Being female, living with spouses/partners, and being a nonimmigrant had a negative association with the lack of using condoms in the last sexual intercourse with casual partners/sex workers, as opposed to having mobility and self-care problems and identifying as a binge drinker. Therefore, workplace-based prevention programs focusing on providing tailored sexual health education and promoting condom use among industrial workers, especially those who are immigrant or migrant workers, in Vietnam should be emphasized.
