ABSTRACT
INTRODUCTION:
There are several negative impacts on the physical and mental health of people presenting internet addiction, including development of mood disorders, such as depression.OBJECTIVE:
The aim of the study was to evaluate the association between internet addiction and depressive symptoms, as well as to test the mediating role of physical activity in this association.METHODS:
A cross-sectional study was conducted with undergraduate students from three universities (one private and two public institutions) in southern Brazil. Depressive symptoms were measured with the Beck Depression Inventory (BDI-21), internet addiction with the Internet Addiction Test (IAT-20), and physical activity with the International Physical Activity Questionnaire (IPAQ - short version). Poisson regression and the Karlson-Holm-Breen mediation method were used for statistical analyses.RESULTS:
We observed a dose-response relationship between internet addiction and depressive symptoms. Levels of physical activity mediated the association between moderate internet addiction and depressive symptoms, accounting for 10.7% of the effect observed.CONCLUSION:
Internet addiction can be detrimental to individuals' health, contributing to development of depressive symptoms. Along with psychological and pharmacological therapies, prescription of physical activities is recommended.Palavras-chave
