# Table 3 Self-reported drinking habits across gender using AUDIT-C and calculated frequencies of risky alcohol consumption using 3 different cut-off levels

AUDIT-C Male % (n) Female % (n) Total % (n) Gender Χ2 (df), p-value
Question 1: Frequency of alcohol use
Never 0.9 (8) 4.1 (20)* 2.0 (28) 49.99 (4), p < 0.001
Monthly 16.7 (150) 25.7 (126)* 19.9 (276)
2–4 times a month 58.0 (520) 57.0 (280) 57.6 (800)
2–3 times a week 21.2 (190) 12.4 (61)* 18.1 (252)
≥4 times a week 3.2 (29) 0.8 (4)* 2.4 (34)
Question 2: Reported alcohol use on a typical day
≤4 units 23.5 (210) 47.4 (225)* 31.8 (435) 81.10 (1), p < 0.001
≥5 units 76.5 (682) 52.6 (250)* 68.2 (934)
Question 3: Frequency of binge drinking (≥6 units)
Never 2.7 (24) 12.6 (61)* 6.1 (85) 114.69 (4), p < 0.001
<Once a month 26.0 (233) 42.2 (205)* 31.7 (438)
Monthly 47.2 (422) 33.3 (162)* 42.2 (584)
Weekly 23.5 (210) 11.5 (56)* 19.4 (268)
Daily or almost daily 0.7 (6) 0.2 (1) 0.5 (7)
AUDIT-C score: Risky alcohol use
> 4 for men, 3 for women 81.0 (726) 73.5 (361)* 78.4 (1087) 10.54 (1), p = 0.001
> 5 for men, 4 for women 68.5 (614) 53.8 (264)* 63.3 (878) 29.74 (1), p < 0.001
≥6 for men & women 68.5 (614) 37.1 (182)* 57.4 (796) 128.37 (1), p < 0.001
1. Frequencies in percent and number (n) of people across the categories of questions of the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) are shown. The frequencies of risky alcohol use according to different cut-offs used in research are presented. The effects of gender were analyzed using Pearson’s chi-squared test followed by the z-test
2. *Column proportions differ significantly (p < 0.05) between men and women. Data is missing for the following variables and number of participants: BAC (n = 2); AUDIT-C question 1 (n = 2), question 2 (n = 8) and question 3 (n = 11)
