英文摘要：

Background: Sexual assault is a form of interpersonal violence with significant consequential health problems worldwide. Substance-involved sexual assault has been increasing in recent years. Many documents revealed that the most common substance used in sexual assault is alcohol, followed by marijuana and cocaine. The prevalence of substances use is different between countries. Aims: We intended to assess the prevalence of substance-involved sexual assault cases in Taiwan. Method: We recruited alleged sexual assault victims at law enforcement agencies or hospitals in the northern, middle and southern parts of Taiwan. Anonymous questionnaires about demographic characteristics, types of sexual assault, suspected drugging, alcohol intake and drug or medication use of victims and offenders were provided and filled questionnaires. The association between substances use and characteristics of victims and sexual assault was analyzed. Results: Among the 646 subjects recruited, 95.2% of victims are females and 4.2% are males. The age ranged from 3 to 65 years (mean, 20.4 years). The assailant was an acquaintance in 87% of cases. According to the victims, there were 19.3% and 3.1% of assailants use alcohol and drugs or medicine before the attack, respectively. Among the victims, 14.1% took alcohol and 5.6% took drugs or medicine before the attack, respectively. Illegal drug taken before the attack was reported in 5.5% (2/36) of victims, and antipsychotic medicine in 8.3% (3/36). Alcohol use of the victims before the assault was associated with the age, occupation, offender-victims relationship and place of occurrence. Conclusions: The prevalence of drug-involved sexual assault in this study was lower than that reported in western countries. This study indicates that, with respect to alleged sexual assault victims, the ethanol is the most commonly use substance before the attack, and the antipsychotic medicine were the most common used drugs or medicine before the attack.
