Donors with VDRL−, EIA+ and FTA‐ABS+ were less likely to be female (AOR=0·26; 95% CI 0·07–0·96), more likely to be older (AOR=10·2; 95% CI 2·45–42·58 ≥ 39 and <60 years old) and to have had more than six sexual partners in the past 12 months (AOR = 8·37; 95% CI 1·49–46·91). There was no significant difference among groups regarding illicit drugs use; 30·7% (VDRL > 8) and 12·5% (VDRL−, EIA+ and FTA‐ABS+) of donors reported that they had been at risk for HIV infection (<italic>P</italic> = 0·004). One‐third of donors came to the blood bank to help a friend or a relative who needed blood.</p> </sec> <sec id="tme12124-sec-0005" sec-type="section"> <title>Conclusion</title> <p id="tme12124-para-0005">Although donors exposed to syphilis reported and recognised some high risk behaviour, most were motivated by direct appeal to donate blood.
