Abstract

The purpose of this study was to explore the relationship between internet addiction level and autonomic nervous system function in college students. The subjects of this study were 138 college students at university located in Deagu. The research design was descriptive correlation study. Data were collected from June 2013 to February 2014, using a questionnaire for measuring internet addiction and heart rate variability (SA-6000, Medicore, Korea) for autonomic nervous system function. The data were analyzed using t-test, ANOVA, Pearson correlation coefficients with SPSS/WIN 18.0. The results of internet addiction level according to the general characteristics of subjects showed a significant difference in gender (t=2.031, p=.044), BMI (t=4.288, p=.016), health status (t=3.317, p=.022), and sleeping status (t=3.975, p=.021). Correlation between internet addiction level and autonomic nervous system function shows that the higher internet addiction level, it seems to have a positive relationship with log TP (r=.281, p=.001), log LF (r=.243, p=.004), LFHF ratio (r=.173, p=.043). It means that internet addiction affects the autonomic nervous system and by accelerating the sympathetic nervous system, it causes the imbalance of sympathetic and parasympathetic system and have influence on autonomic nervous system. It is necessary to develop an intervention program to prevent and eliminate internet addiction.

본 연구는 대학생을 대상으로 인터넷중독 정도와 자율신경계 기능과의 관계를 알아보고자 시도된 서술적 상관관계 연구이다. 대구지역 소재 대학의 재학생 138명을 대상으로 인터넷중독 척도 설문지와 자율신경계 기능 측정을 위한 심박변이도(HRV; heart rate variability) 검사를 실시하였다. 연구기간은 2013년 6월부터 2014년 2월까지 이루어졌으며, 자료분석은 SPSS/WIN 18.0 통계프로그램을 이용하여 t-검정(t-test), 분산분석(ANOVA), Pearson's 상관계수(correlation coefficient)로 분석하였다. 대상자의 일반적 특성에 따른 인터넷중독 정도는 성별(t=2.031, p=.044), BMI(t=4.288, p=.016), 건강상태(t=3.317, p=.022), 그리고 수면상태(t=3.975, p=.021)에서 유의한 차이가 있는 것으로 나타났다. 인터넷중독 정도와 자율신경계 기능의 상관관계는 인터넷중독 정도가 높을수록 log TP(r=.281, p=.001), log LF(r=.243, p=.004), LF/HF ratio(r=.173, p=.043)가 유의한 정적 상관관계가 있는 것으로 나타났다. 이는 인터넷중독이 자율신경계 활성화에 영향을 미치며, 특히 교감신경계의 활성화로 교감신경과 부교감신경 균형의 변화를 유도하는 것을 의미한다. 이에 인터넷중독 대학생을 위한 중재 프로그램 개발 시 자율신경계를 안정화시키는 내용도 포함시킬 필요가 있을 것으로 생각된다.
