HIV-related sexual behaviour among migrants and non-migrants in a rural area of China: role of rural-to-urban migration.

摘要

OBJECTIVE: To compare human immunodeficiency virus (HIV)-related sexual risks between temporary rural-to-urban migrants and non-migrants, and to explore the role of migration in HIV transmission in a rural area of China. STUDY DESIGN: A cross-sectional study was conducted among 605 (302.5 couples, one male missing) marriage licence applicants. METHODS: A two-part anonymous questionnaire was used. The first part included non-sensitive questions including demographics and HIV knowledge. Sensitive questions related to sexual behaviours were administered in the second part of the questionnaire using a tape recorder, earphones and an answer sheet. RESULTS: Sixty-six percent (399/605) of the study subjects had migrated to a city for a temporary job. The proportions of migrants who had premarital sex (62%, 247/399) and multiple sexual partners (12%, 47/399) were significantly higher than those of non-migrants (52 and 6%, respectively). Among those who had multiple sexual partners, only 9% (4/47) of migrants and 8% (1/12) of non-migrants reported often or always using condoms with sexual partners other than their spouse. A low level of knowledge regarding HIV and acquired immunodeficiency syndrome was observed in both groups. Very few migrants (15%, 61/399) and non-migrants (10%, 20/206) perceived themselves to be at risk of HIV infection. CONCLUSIONS: As both migrants and non-migrants are at risk of HIV infection, intervention programmes targeting reduction of HIV sexual risk behaviour should cover both groups in rural areas of China.
