[An analysis of factors associated with timeliness of antiretroviral therapy initiation among newly diagnosed HIV/AIDS from 2010 to 2014 in China].

To analyze timeline of antiretroviral therapy (ART) initiation among newly diagnosed HIV/AIDS from 2010 to 2014, as well as influencing factors. Data from the Chinese HIV/AIDS Comprehensive Response Information Management System was used to collect newly diagnosed HIV/AIDS cases from January 1, 2010 to December 31, 2014. Inclusion criteria of HIV/AIDS were confirmed cases and clinically diagnosed HIV positive, Chinese mainland cases, 14 years old and above, the first CD4(+)T lymphocyte ≤350 cells/μl in the follow up period. A total of 177 971 HIV/AIDS cases were included in this study. The general demographic characteristics (gender, age, ethnicity, education, occupation, etc.), infection routes, sample sources, CD4(+)T lymphocyte level and other information were collected from the database. Chi square test was used to analyze univariate factor of the timeliness of ART initiation. Multivariate logistic regressions were used to analyze potential factors associated with timeliness of ART initiation. Out of the 17 7971 cases, 130 679 (73.4%) were males. The proportion of the timeliness of ART initiation was 55% (97 915). The proportion of timeline of ART within 15 d increased from 26.4% (4 319/16 388) in 2010 to 39.7% (20 212/50 889) in 2014. The highest proportion was in the group of patients infected by illegal blood (plasma) donation, which was 38% (945). The proportion of timeline of ART within 30 d increased from 43.2% (7 077/16 388) in 2010 to 63% (32 070/50 889) in 2014.The highest proportion was in the group of patients infected by heterosexual transmission, which was 58.3% (73 098). Multivariate logistic regression analysis on timeliness of ART showed that the factors of timeliness of ART initiation of HIV/AIDS as follow. The possibility of timeliness of ART among patients who were female, education of junior high school and above, ethnic group of Han, farmers, married were higher, with values at 1.08, 1.09, 1.13, 1.05 and 1.12. The possibilities of timeliness of ART in group of patients aging 25-34, 35-44, 45-54 and ≥55 years old were higher than that of the group of patients aging 15-24 years old, with values at 1.13, 1.31, 1.46 and 1.51, respectively. The possibilities of timeliness of ART among the homosexuals, injection drug use and sexual contact plus injection drug use cases were lower than that of the heterosexuals, with values at 0.86, 0.59 and 0.72, respectively. The possibilities of timeliness of ART among patients whose HIV diagnosis from hospitals and detention centers were lower than that of patients whose HIV diagnosis from volunteer testing and counseling, with values at separately 0.90 and 0.29. The possibilities of timeliness of ART among patients whose CD4(+)T lymphocyte at 50-99, 100-199, 200-350 cells/μl were lower than that of the patients whose CD4(+)T lymphocyte count at 0-49 cells/μl, with values at 0.84, 0.64 and 0.40, respectively. All the P values above was<0.05. The proportion of timeliness of ART increased annually from 2010 to 2014. Those who were men, unmarried or divorced, at younger age, injection drug use, diagnosis from hospitals and detention centers and high CD4(+)T lymphocyte levels were related to the timeliness of ART.
