The largest occurred during the birthday week of 19 years of age, the beginning of the minimum legal drinking age (MLDA) in Ontario: AUD admission rates increased (spiked) by 38.30 per 1000 total admissions [95% confidence interval (CI) = 34.66–41.94] among males (a 114.3% increase over baseline), and by 28.13 (95% CI = 25.56–30.70) among females (a 164.0% increase). Among both genders, the second largest birthday‐week spikes occurred during ages 20–22 years, followed by somewhat lower but still pronounced birthday‐week spikes during ages 23–26 years and 30 years (all these spikes: <italic>P</italic> < 0.05). Birthday‐week spikes occurred as early as age 16 years for males and 14 years for females (both spikes: <italic>P</italic> < 0.05).</p> </sec> <sec id="add12626-sec-0007" sec-type="section"> <title>Conclusions</title> <p>There appears to be an increase in alcohol‐related adverse events from drinking around the time of one's birthday among young adults in Canada.</p> </sec> </abstract>
