Introduction:
Targeted intervention (TI) project aimed to interrupt HIV transmission among highly vulnerable population and their clients.
Aims And Objectives:
To compare survival among HIV-positive versus survival among HIV-negative women.
Subjects And Methods Study Design:
Prospective cohort with retrospective comparison.
Study Setting:
Two drop in center clinics.
Study Tool And Process Of Data Collection:
Data were collected for 5 years from 2009 to 2014. Pretested semi-structured questionnaire was used for data collection.
Results:
The mean age of high-risk women was 32.48 ± 4.67 years. The mean survival among HIV-negative women was 110.62 ± 0.6 months and mean survival among HIV-positive women was 91.09 ± 7.67 months. The mean interval to death among women with sexually transmitted diseases (STDs) was 113.50 ± 1.30, whereas the mean interval to death among women with no STDs was 105.65 ± 0.76. P = 0.00 by log-rank test.
Conclusion:
Status of high-risk women according to HIV, STDs, typology, category and partner wise were found to have a significant difference in survival experience, whereas PRR positivity for syphilis, literacy, alcohol intake do not have a significant difference.
