To determine the prevalence of suicidal ideation and examine the association between suicidal ideation and sociodemographic characteristics, protective and risk factors among Jamaican youth.
In this cross-sectional study, an interviewer administered school-based survey was conducted among 2997 students 10-15 years old in Jamaica. Although there were a number of questions on suicide, this paper focusses on one question "During the past year did you ever seriously consider attempting suicide?" as the measure of suicidal ideation.
The prevalence rate of suicidal ideation was 9.7%. Logistic regression analysis revealed that significant correlates of suicidal ideation were being female (odds ratio = 1.49), being depressed (odds ratio = 5.78), living in a rural area (odds ratio = 0.62), likes oneself (odds ratio = 0.58), indulging in aggressive behaviour (odds ratio = 1.43), has considered harming others (odds ratio = 3.11), protective factors in the home (odds ratio = 0.62), involvement in risky behaviour (odds ratio = 1.56) and being teased/bullied (odds ratio = 1.69).
These findings have implication for prevention and treatment of suicidal behaviour in children and adolescents.
确定牙买加青少年自杀意念的患病率，并研究自杀意念与社会人口学特征、保护因素和风险因素之间的关联。
在这项横断面研究中，对牙买加2997名10至15岁的学生进行了由访员实施的基于学校的调查。尽管有许多关于自杀的问题，但本文重点关注一个问题“在过去一年里，你是否曾认真考虑过自杀未遂？”作为自杀意念的衡量标准。
自杀意念的患病率为9.7%。逻辑回归分析显示，自杀意念的显著相关因素包括女性（优势比=1.49）、抑郁（优势比=5.78）、生活在农村地区（优势比=0.62）、喜欢自己（优势比=0.58）、沉溺于攻击性行为（优势比=1.43）、曾考虑伤害他人（优势比=3.11）、家庭中的保护因素（优势比=0.62）、参与危险行为（优势比=1.56）以及被取笑/欺负（优势比=1.69）。
这些发现对儿童和青少年自杀行为的预防和治疗具有启示意义。
