The mediating effect of sleep satisfaction on the relationship between stress and perceived health of adolescents suffering atopic disease: Secondary analysis of data from the 2013 9th Korea Youth Risk Behavior Web-based Survey

Abstract

Background: Difficulty in sleep is one disturbing symptom in adolescents with atopic diseases including asthma, allergic rhinitis, and atopic dermatitis. Assuming psychological stress can affect adolescents' health status, impaired sleep quality can be one mediator that negatively impacts the health status of adolescents with atopic disease. Objectives: This study aimed to identify the mediating effect of sleep satisfaction on the relationship between stress and perceived health status in Korean adolescents with atopic disease and to examine the differences among three types of atopic disease. Design: A cross-sectional descriptive study was completed based on secondary analysis of raw data from the 2013 9th Korea Youth Risk Behavior Web-based Survey. Settings and participants: The 21,154 adolescents (29.2%) ever diagnosed and treated for at least one atopic disease regardless of the symptom presence in a recent year were extracted out of 72,435 survey participants. Then, the 13,216 individuals with exclusively single atopic diseases were included in analyzing the mediation model. Methods: Variables including demographics, stress, perceived health status, and sleep satisfaction were included. Pearson correlation, one-way ANOVA, path analysis to define direct/indirect effects with bootstrapping analysis, and multi-group variance analysis were conducted. Results: High levels of stress in adolescents with atopic diseases had a significant and direct effect on their negative health status perception for all atopic disease groups. A significant negative mediating effect of sleep satisfaction was identified on the relationship between stress and perceived health status, irrespective of the type of atopic disease. Total effect and remaining direct effect on the path from stress and perceived health status via sleep satisfaction was high in adolescents with atopic dermatitis and allergic rhinitis compared to those with asthma. Conclusions: To improve sleep satisfaction for adolescents with atopic diseases, interventions are needed to enhance the adolescents' perceived health status through stress reduction and sleep quality improvement.
