Young adults aged 18 to 32 years were randomly selected from a household probability sample participating in Project Accept in the remote areas of Chiang Mai province in northern Thailand in 2005. Among 2989 respondents, 44.4\% had never heard of antiretroviral treatment (ART).
Younger participants were less likely to intend to get an HIV test as compared with older individuals, and ethnic minorities were less likely to report that they would get an HIV test compared with Thai lowlanders. Single individuals and people who lived separately from their spouses were more likely to have the intention to use condoms if ART were available.
