Factors Influencing Adolescent Generalized Anxiety Disorder: A Zero-Inflated Negative Binomial Regression Model

The current study used secondary data from the 17th Korea Youth Risk Behavior Survey conducted in 2021 to identify risk factors influencing the frequency with which adolescents in Korea experience generalized anxiety. Participants were 54,848 adolescents. Risk factors for generalized anxiety were analyzed using a zero-inflated negative binomial regression model. Of participants, 23.7% reported no generalized anxiety experiences. Risk factors identified in the count model were being female and having low household economic status as well as perceived stress, sadness, subjective sleep insufficiency, and loneliness. In the logit model, being female, in middle school, having middle and low household economic status, not living with family, having perceived stress, sadness, suicidal ideation, subjective sleep insufficiency, loneliness, and body image distortion were significant predictors of future anxiety among participants without anxiety. These results may be useful for planning nursing interventions to improve and prevent future health problems in adolescents.
