Introduction

cross-sectional school-based epidemiological survey, conducted in 2016 and 2017, from a representative sample of 15 to 19-year-old students enrolled in the Greater Vitória Metropolitan Region (RMGV-ES), Espírito Santo, Brazil.

Objectives

to analyze the association between Internet Addiction, sociodemographic characteristics and the pattern of Internet and social media use.

Methods

cross-sectional study with 2293 students. The sociodemographic data of the individuals and information on internet and social media dependence were verified using the Internet Addiction Test (IAT). Frequencies were calculated and Chi-square and Binomial Logistic Regression tests were applied.

Results

internet addiction was associated with adolescents in the early years (p = 0.001), those with less-educated household heads (p = 0.018), and those who spent four or more hours a day surfing the internet (p < 0.001) and those who used the Internet every day of the week (p = 0.004). Internet addiction was also associated with the use of Twitter (p-value = 0.040), subjective reasons for use (p = 0.001) and those who stopped using it for social reasons (p = 0.001).

Conclusion

It is recommended that daily screen time should not exceed four hours. Therefore, the implementation of public policies aimed at educating adolescents and their families, as well as protection aimed at the most susceptible individuals, are essential for the best growth and development of adolescents.
