Descriptive epidemiology methods and logistic regression analysis were adopted in the study.
Results Of the 574 HIV/AIDS patients, 202 were categorized as LTNP according to the strict definition of LTNP, accounting for 1.6% of all registered HIV/AIDS patients (12 545) during the 19-year period in the region. Among the 202 LTNP, 95 were alive and followed up. The results of multivariate logistic regression analysis revealed that age, route of the infection, status of antiretroviral therapy, and whether being followed-up were the influencing factors of LTNP.
