[Prevalence of problem drinkers among dental students]

In 1997 and 1998 we statistically studied fourth-year dental students for their drinking and smoking habits. The subjects numbered 103 (65 males, 38 females) in 1997 and 127 (79 males, 48 females) in 1998, totaling 230. The questionnaire included the Kurihama Alcoholism Screening Test (KAST), the Adolescent Alcohol Involvement Scale (AAIS), and the Fagerström Tolerance Questionnaire (FTQ). Problem drinkers as defined by KAST, scoring at least 2 points, represented 12.6% of the total in 1997 and 13.4% in 1998, exceeding 10% in both years. Alcoholic misusers, with at least 42 point on the AAIS, stood at 19.4% in 1997 and 17.3% in 1998. The incidence of students assessed as having 6 points on the Quantity-Frequency Scale (QF Scale) stood at 18.4% in 1997 and 10.2% in 1998. Compared between two sexes, KAST detected no significant difference between the two groups: 13.9% for males and 11.6% for females. Alcoholic abusers on the AAIS, however, were estimated at 22.9% in males and 9.3% in females, the ratio for males being more than twice as high as that for females. It was also found that 47.9% of the male students and 33.7% of their female counterparts drank every weekend and that 31.3% of the males and 5.8% of the females kept drinking until they were drunk. Female students thus appeared to drink more frequently, though they consumed smaller amounts of alcohol at a time. The smoking rate was lower than the average in the Japanese for both groups; nicotine dependence was also lower in dental students. It was demonstrated that dental students drink more alcohol more frequently, with a higher incidence of problem drinkers.
