A total of 2,319 unique individuals who started
TVD for PrEP between 01 Jan 2012 and 30 Sep
2013 were included in the analysis.
• 48.8% of PrEP users were women.
• Mean age was 38.2 ± 12.2 years
• Males were significantly older (39.5 ±
12.0) than females (36.8 ± 12.3).
p<0.0001
• 12.3% of individuals were under 25 years old.
• The proportion of males under 25 was
8.0% (95% CI 6.5 – 9.5) significantly lower
than that of women 16.8% (95% CI 14.6 –
19.0). p<0.0001
