選取高雄地區某國中全校學生共3548位(回收率98.6%)作為使用安非他命之危險因素研究的對象。以作者自行發展並評估過的問卷,作無記名問卷調查,分析3200份完整的資料(佔90.2%),回答有使用安非他命的經驗的85位學生當成個案組,其餘回答沒有使用而且尿液分析也陰性的學生當成對照組,對兩組相關因素包括人口學特徵進行比較,並將較具顯著意義的相關因素作邏輯迴歸分析。 經調整分析後,對於使用過安非他命的危險因素有下列六項:男性對女性學生的差異比為3.52(95%CI=1.04-11.90),沒有與父母同住對有與父母同住的差異為2.96(95%CI=1.19-7.33),有同學或朋友使用安非他命對無者的差異比為7.13(95%CI=2.87-17.73),學生本身有抽煙對不抽煙者的差異比為9.24(95%CI=1.07-79.61),學生本身有嚼食檳榔對不嚼食者的差異比為11.44(95%CI=3.09-42.35),態度中想嘗試使用對不願嘗試使用的差異比為9.57(95%CI=3.10-29.57)。 學生開始抽煙的平均年齡為12歲7個月,接著開始喝酒,嚼食檳榔,使用安非他命,初用安非他命的平均年齡13歲7個月,使用率並有隨著年齡增加而增加的趨勢(P trend=0.001),在使用動機中,好奇心驅使的為65.4%。安非他命的來源,從校外的朋友來的為54.2%。本研究對象有使用此葯者約85.2%的學生都是在1990年8月到1991年1月這段期間內使用。
The prevalence of amphetamine abuse among school children was studied by asking 3548 adolescent students (aged 12-15, response rate 98.6%) to complete a questionnaire anonymously, which was developed and eva-luated by the authors. A complete set of data was collected for 3200 (90.2%)students. Eighty-five (2.7%) of them who admitted that they had used amphetamines constituted the case group. Non-users with negative urine tests formed the control group. Six independent factors were found to be related to amphetamine use when the answers were analyzed by stepwise logistic regression. The prevalence odds ratio estima-tion was elevated in: males compared females, students who did not live with both parents compared to those who lived with both parents, students with amphetamine-user friends compared to those with no-user friends, smokers compared to non-smoker, betel nut chewers compared non-chewers, and in stu-dents with positive attitudes compared to those with negative attitudes. The average starting age for smoking was 12.5 ± 0.1 years; later this was followed by alcohol abuse, chewing of betel-nuts, and use of amphetamines. The average age of starting to use amphetamines was 13.5 ± 0.2 years; a common reason given for using amphetamines was curiosity (65.4%) used it six months before responding to the questionnaire.
