We estimated sex-\/gender-specific associations between SEP (both education and income) and heavy episodic drinking (\u22655 standard drinks on one occasion, at least monthly) or volume of alcohol use (standard drinks per week) on incident alcohol-attributable ED visits and assessed additive interactions using the Synergy Index (S).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Lower levels of education (eg, less than high school vs Bachelor\u2019s degree or above: men: adjusted HR (aHR)=3.71, 95% CI 2.47 to 5.58; women: aHR=1.75, 95% CI 1.15 to 2.68) and income (eg, quintile (Q)1 vs Q5, men: aHR=2.07, 95% CI 1.35 to 3.17; women: aHR=1.84, 95% CI 0.91 to 3.71) were associated with increased rates of alcohol-attributable ED visits.
