title: [Survey on Blastocystis hominis infection in HIV positive individuals in Fuyang City, Anhui Province].
abstract: OBJECTIVE
  To understand the epidemiological characteristics of co-infection of HIV and Blastocystis hominis and its risk factors.
  
  
  METHODS
  A total of 309 people with HIV positive in the development zone of Fuyang City were recruited, and the face to face questionnaires were conducted to collect the information of behavioral characteristics and sociodemographic data of the participants. Meanwhile, the samples of stool and blood were collected to test B. hominis, cytokines and CD4+/CD8+ T-lymphocyte. The influencing factors of co-infection of HIV and Blastocystis hominis were analyzed by the single factor analysis and Logistic regression analysis.
  
  
  RESULTS
  Among the 309 people involved, 302 accepted feces examinations, 286 accepted the questionnaire investigation, and 263 accepted both of them. The infection rate of B. hominis was 17.11%, that of the female was 21.90%, which was significantly higher than that of the male (11.90%) (P < 0.05). The results from the multivariate Logistic regression model showed that good nutrition was significantly associated with the co-infection of HIV and B. hominis (OR = 0.263, 95% CI: 0.073, 0.945).
  
  
  CONCLUSIONS
  The infection rate of B. hominis is high in people with HIV positive, and the nutrition situation of individuals may be one of the important risk factors associated with co-infection.
