What is known on the subject?
Adolescents who partake in one health risk behaviour (HRB) easily adopt other HRBs, simultaneously or subsequently.
Multiple HRBs might threaten adolescents’ future health in adulthood.
Adolescents with psychological problems have higher rates of smoking, alcohol use, early sexual initiation and activity, and illicit substance use compared with others.
What does this paper add to existing knowledge?
A considerable number of Korean adolescents with mental health problems were engaged in multiple HRBs. For those with mental health problems, more than half of the Korean adolescents with multiple HRBs tended to use alcohol and cigarettes concurrently.
Korean adolescents who felt depressed and had suicidal ideation were more likely to engage in a greater number of HRBs.
Substance abuse is the most prevalent problem that is combined with other HRBs among those with depression and suicidal ideation compared to those who exhibited other HRBs.
What are the implications for practice?
When mental health nurses working in schools and community centres for mental health identify Korean adolescents with significant depression and suicide ideation levels, they should also assess adolescents’ engagement in multiple HRBs.
Population‐based campaigns and policy changes that emphasize both psychological health and risky behaviour reduction among adolescents should be provided simultaneously to students and school nurses.
Abstract
IntroductionThere is limited understanding about whether poor mental health is associated with certain combinations of multiple health risk behaviours (HRBs) such as smoking, drinking, early sexual activity and substance abuse.
AimTo determine the prevalence of multiple HRBs and to identify associations between poor mental health and multiple HRBs as the number of HRBs increases.
MethodsThis cross‐sectional study was conducted using the 2016 Korea Youth Risk Behavior Web‐based Survey (N = 65,528). Descriptive statistics and multinomial logistic regression analyses were conducted using the complex sample data.
ResultsOverall, 28.6% and 13.9% of Korean adolescents were involved in one or multiple HRBs, respectively. Adolescents who were depressed (OR = 1.43–4.47, 95% CI = 1.37–1.49 to 3.23–6.20) and/or who had suicidal ideation (OR = 1.33–3.19, 95% CI = 1.25–1.42 to 2.25–4.51) were more likely to engage in multiple HRBs.
DiscussionA considerable numbers of Korean adolescents are engaged in multiple HRBs. When adolescents self‐reported depression and suicidal ideation, they were more likely to engage in a greater number of HRBs than single HRB.
Implications for practiceTailored interventions to decrease multiple HRBs should be designed and provided by considering adolescents’ mental health status and needs.
