Prevalence and risks for sexually transmitted infections among a national sample of migrants versus non-migrants in China.

This study aims to describe and compare the gender-specific prevalence of chlamydia and gonorrhoea, sexual behaviours and experiences, and risk factors associated with sexually transmitted infections (STIs) among migrants versus rural and urban non-migrants in China. Data were abstracted from the Chinese Health and Family Life Survey conducted from 1999 to 2000, which provided a nationally representative adult (ages 20-64 years) sample. STI results were determined using a urine-based nucleic acid amplification assay. The prevalence of chlamydia for migrant women was triple that of rural non-migrant women. Migrants were more likely to engage in STI-associated risk behaviours than non-migrants (e.g. receiving money for sex). Among migrants, women were more likely than men to have STIs. The high STI prevalence among migrants highlights an urgent need to implement comprehensive prevention and intervention programmes targeting the cultural, social and structural needs of migrants in the city, especially migrant women.\ud \u
