title: Prevalence and correlates of HIV discordance and concordance among Chinese-Burmese mixed couples in the Dehong prefecture of Yunnan province, China.
abstract: BACKGROUND
  Many people from Burma have migrated to Dehong prefecture and married local residents during the past decades; however, little is known about HIV risk-taking behaviours and HIV prevalence among these mixed couples. We investigated factors correlated with HIV discordance and concordance within Chinese?Burmese mixed couples in Dehong prefecture, Yunnan province, China.
  
  
  METHODS
  A cross-sectional study with face-to-face questionnaire interviews and HIV blood testing was conducted.
  
  
  RESULTS
  Of 5742 couples, 1.6% couples were HIV-infected concordant, 2.2% were HIV serodiscordant with an HIV-infected male spouse and 0.9% were HIV serodiscordant with an HIV-infected female spouse. HIV discordance with an HIV-infected male spouse was significantly associated with characteristics of the male spouse, including being aged =30 years, non-Han ethnic minority, a marital relationship of <3 years, commercial sex and injection drug use by the male spouse. HIV discordance with an HIV-infected female spouse was significantly associated with an education level of primary school (v. illiterate); a marital status of being in their second marriage, widowed or divorced; a history of sexually transmissible infection diagnosis of the female spouse; noncommercial extramarital sex by the female spouse or by both spouses; and injection drug use by the male spouse. A marital relationship of =3 years was the only significant independent correlate of HIV-infected seroconcordance.
  
  
  CONCLUSIONS
  The study findings underscore the importance of premarital HIV counselling and testing for this population, and the need for targeted interventions among HIV serodiscordant mixed couples to reduce secondary transmission as early as possible when the relationship begins.
