Around the world, one of the main concerns and risky behaviors among youths is methamphetamine consumption. Since the age of onset of methamphetamine use is decreasing, therefore, it is important to identify the effective factors on the age of onset of methamphetamine consumption. In the present study, factors affecting the age of onset of methamphetamine consumption was studied in Iranian youths aged 19-29 years.
In this cross-sectional nationwide study, individuals aged 19-29 years were selected through multistage cluster sampling and convenience sampling method from 13 provinces in Iran. People completed the questionnaire pertaining to knowledge, attitude, and history of methamphetamine consumption. In order to investigate the factors effective on the age of onset of methamphetamine consumption, we used the Weibull parametric model for data with doubly censored characteristic.
3246 people participated in this study, half of whom were men and mostly single (60.3%), university student or graduate (50.2%), and unemployed (58.1%). Nearly 6% of participants have ever used methamphetamine. Mean and standard deviation (SD) of age of onset of methamphetamine use was 20.3 ± 3.3 years. Data analysis indicated that the variables of gender, marital status, education, knowing a methamphetamine consumer, knowing an ecstasy consumer, ecstasy consumption, illegitimate sex, attitude towards methamphetamine, and age group were the factors affecting the age of onset of methamphetamine consumption.
The results can contribute to the policy-makers to take the necessary interventions on the factors affecting the age of onset of methamphetamine consumption to reduce the methamphetamine consumption, especially in the critical young ages.
在全球范围内，青少年的主要担忧和危险行为之一是甲基苯丙胺消费。由于甲基苯丙胺使用的起始年龄正在下降，因此，确定影响甲基苯丙胺消费起始年龄的有效因素非常重要。在本研究中，对19至29岁的伊朗青少年中影响甲基苯丙胺消费起始年龄的因素进行了研究。
在这项全国性横断面研究中，通过多阶段整群抽样和便利抽样方法，从伊朗13个省份选取了19至29岁的个体。人们完成了与甲基苯丙胺消费知识、态度和历史相关的问卷。为了调查对甲基苯丙胺消费起始年龄有影响的因素，我们对具有双重删失特征的数据使用了威布尔参数模型。
3246人参与了本研究，其中一半为男性，大多数为单身（60.3%）、大学生或毕业生（50.2%）以及失业者（58.1%）。近6%的参与者曾使用过甲基苯丙胺。甲基苯丙胺使用起始年龄的均值和标准差分别为20.3±3.3岁。数据分析表明，性别、婚姻状况、教育程度、认识甲基苯丙胺使用者、认识摇头丸使用者、摇头丸消费、非婚性行为、对甲基苯丙胺的态度以及年龄组等变量是影响甲基苯丙胺消费起始年龄的因素。
研究结果有助于政策制定者针对影响甲基苯丙胺消费起始年龄的因素采取必要干预措施，以减少甲基苯丙胺消费，尤其是在关键的青少年时期。
