Is Alcohol Consumption Pattern Dependent on Prenatal Sex-Steroids? A Digit Ratio (2D:4D) Study Among University Students

Abstract

Introduction: There is evidence that alcohol consumption is influenced by prenatal sex steroids (as measured by digit ratio [2D:4D]). Here, we clarify the effect size of the relationship in a student (rather than a patient) population. Methods: There were 258 (169 women) participants. Digit length was measured directly with calipers. Alcohol use was evaluated by the Polish version of Alcohol Use Disorders Identification Test (AUDIT) and operationalized as total AUDIT scores and grams of alcohol/week. Results: Digit ratios were sexually dimorphic (males
