Categories used commonly consumed gr / day

Moderate (up to 21 units [10 ml of neat alcohol] per week for men and 14 units for women) /Hazardous (21–50 units men, and 14–35 women and Harmful (more than 50 units for men and more than 35 for women)

Alcohol consumption is measured by five categories of daily intake of grams of pure alcohol: 0–< 0.25 g/d, 0.25–< 20 g/d, 20–< 40 g/d, 40–< 60 g/d, ≥60 g/d.

for women: abstinence (no alcohol consumption), moderate (less than two standard drink units per day), excessive consumption (between two and four per day), and dangerous consumption (more than four per day), for men: abstinence (same), moderate consumption (fewer than four per day), excessive consumption (between four and six per day) and dangerous consumption (more than six per day)

Results in decrease in net grams or drinks (standard units) per day

Drinker I (females 0–19.99 g pure alcohol daily, males 0–39.99 g pure alcohol), Drinker II (females 20–39.99 g pure alcohol, males 40–59.99 g pure alcohol) and Drinker III (females ≥40 g pure alcohol, males ≥60 g pure alcohol).

Heavy or Dangerous (>  20 g per day for women and > 40 g per day for men)
