A total of 15\u2009549 junior and senior high school students (7645 boys and 7904 girls) were included. Current alcohol consumption was defined as drinking on at least 1\u2009day in the past 30\u2009days. Multivariable logistic regression analyses were used to examine associations between current alcohol consumption and lifestyle factors, including irregular sleep patterns, irregular dietary habits, and increased screen time. Sex\u2010stratified analyses and interaction tests were also performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The overall prevalence of current alcohol consumption was 2.1%, with slightly higher rates among boys (2.2%) than girls (2.0%). Current alcohol consumption was significantly associated with irregular sleep patterns (odds ratio [OR]\u2009=\u20091.51; 95% confidence interval [CI], 1.17\u20131.95) and irregular dietary habits (OR\u2009=\u20091.68; 95% CI, 1.18\u20132.40). An association with increased screen time was also observed (OR\u2009=\u20091.29; 95% CI, 1.00\u20131.69), particularly among boys. A significant interaction by sex was detected for irregular sleep patterns (\n                      <jats:italic>p<\/jats:italic>\n                      for interaction\u2009=\u20090.013).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Alcohol consumption among Japanese adolescents was associated with irregular sleep and dietary habits and, among boys, with increased screen time.
