Prevalence and profile of methamphetamine users in adolescents at a juvenile classification home.
The objective of the present study was to investigate the prevalence and risk factors of methamphetamine use in adolescents at a juvenile classification home. The present subjects were 1362 adolescents (1172 male and 190 female) who had been admitted to the Nagoya Juvenile Classification Home. The participants were divided into two groups, a methamphetamine user group and a control group, based on history of methamphetamine use. The presence of methamphetamine use was analyzed in terms of gender, age, number of admissions, violence (types of crime), history of psychiatric treatment, family history (crime, drug misuse and/or alcohol-related disorder), and experience of being abused by their parents or by the persons who were responsible for raising them. The prevalence of methamphetamine use was 6.8% (93/1362). Multivariate logistic regression analyses indicated that gender (female; odds ratio [OR]: 8.1; 95% confidence interval [CI]: 4.6-14.3), age (OR: 1.8, 95%CI: 1.5-2.1), number of admissions (>2, OR: 2.9, 95%CI: 1.8-4.8), violence (OR: 0.4, 95%CI: 0.2-0.7), history of psychiatric treatment (OR: 8.7, 95%CI: 4.0-19.0), and family history of drug misuse (OR: 4.0, 95%CI: 1.6-9.6) were all significantly associated with methamphetamine use. Approximately 7% of participants used methamphetamine. Female gender was a risk factor. Higher age and multiple admissions suggest the persistency and repetition of delinquency. Methamphetamine users were less violent than control subjects. Psychosocial environment (family history of drug misuse) and psychiatric problems (history of psychiatric treatment) were also related to methamphetamine use.
