While Western settings often rely on objective measures like BAC for identifying alcohol\u2010related RTIs, self\u2010reporting may be more viable in contexts with limited resources and different cultural norms. This study aimed to (1) compare self\u2010reported alcohol use with breathalyzer\u2010confirmed BAC results and (2) identify factors associated with BAC positivity among RTI patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>This was a cross\u2010sectional study of RTI patients conducted at two Cameroonian hospitals.

The median age was 35\u2009years (interquartile range\u2009=\u200916).

The NPV was high (93.8%), while the PPV was low (46.5%). Non\u2010detection of BAC in positive self\u2010report cases was common: 73.1% of those reporting 1\u20132 drinks were BAC\u2010negative, but all who reported &gt;2 drinks were BAC\u2010positive. In adjusted models, male sex [adjusted odds ratio (AOR)\u2009=\u20093.99, 95% confidence interval (CI) = 1.4\u201313.6], alcohol use disorder (AOR\u2009=\u20098.11, 95% CI = 3.3\u201321.6) and nighttime injury (AOR\u2009=\u20094.42, 95% CI = 2.1\u20139.5) were independently associated with BAC positivity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In Cameroon, self\u2010reported alcohol use appears to be a practical and sensitive tool for ruling out non\u2010drinkers and identifying high\u2010risk road traffic injury patients, especially where blood alcohol level testing is unavailable.
