Results: Overall, 7279 (8.4% or 8354 per 100,000) of respondents reported that their most serious injury
in the 12 months prior to recruitment in the cohort was transport-related, with risk being higher for
males and those aged 15–19 years. Most transport injuries occurred while using motorcycles. A much
higher proportion of males reported driving after three or more glasses of alcohol at least once in the
previous year compared to females. The prevalence of motorcycle helmet and seat belt wearing in this
sample were higher than previously reported for Thailand.
