“…Many new users are expected to emerge from developing countries through greater device affordability, growing economies, and young, growing populations [9]. Several studies have examined the relation between smartphone use and common mental disorders [10,11,12,13,14]. Without statistically adjusting for other relevant variables, depression severity was consistently related to problematic smartphone use [15].…”

Background: Smartphones are an integral part of modern communication but addiction to these devices could predispose to common mental disorders. Objectives: To determine the prevalence of smartphone addiction and common mental disorders as well as the association between smartphone addiction and these mental disorders in Dschang university students who use smartphones. Methods: A cross-sectional study was conducted. Randomly selected students completed a survey comprising Patient Health Questionnaires seven and nine (PHQ-9 and PHQ-7) to screen for depression and anxiety respectively, and the Smartphone Addiction Scale-Short Version (SAS-SV) to grade smartphone use. The association between smartphone use and common mental disorders was assessed using logistic regression modelling. Results: We recruited 634 participants. The prevalence of smartphone addiction was 20.98% [C.I:17.99%-24.32%]. The prevalence of depression and anxiety were 34.86% [95% CI: 31.25-38.65] and 19.27% [95% CI: 16.81-22.99] respectively. The odds of depression in students with addiction was 5 times the odds of depression in students without addiction [OR: 4.96, 95% CI: 3.30-7.45, p<0.001]. The odds of anxiety in students with addiction was 2 times the odds of anxiety in students without addiction [OR: 2.44, 95% CI: 1.58-3.77, p<0.001]. After adjusting for age, sex, faculty, cycle of study, marital status, religion, chronic diseases, sexual abuse and suicidal ideation, there remained a statistically-significant association between smartphone addiction and both depression [OR: 4.46, 95%CI; 2.92-6.84, p<0.001] and anxiety [OR: 2.08, 95% CI; 1.31-3.30, p=0.002]. Conclusion: In this setting, it is crucial to foster strategies of prevention and promotion in mental health especially among problematic smartphone users.

“…As ownership and accessibility to mobile smartphones become ubiquitous so does the need for research into the implications, such as positive and negative health consequences. Recent research suggests high screen media usage is associated with poor sleep and diminished academic performance among adolescents and adults [5][6][7]. Thus, accurate and feasible methodologies to study mobile screen time are necessary to further understand these relationships.…”

“…These factors may cause higher use of smartphone or electronic media devices among young adults, such as university students [5]. Prolonged smartphone use could cause a decrease in overall physical functional activities as well as the development of primary problems, such as problems with vision and hearing, and secondary problems, such as problems with visual perceptive function, visual memory, and cognitive function [3,6]. In particular, smartphone overuse alters the visual images associated with visuoperceptual and cognitive function during the use of a smartphone [3,5].…”

“…Subclinical neck pain may impair the ability to perform a complex mental rotation task involving cerebellar connections, possibly due to an altered body schema [6,9]. However, previous studies have not measured brain activation during investigations of differences in simple visual imagery and mental rotation imagery with regard to smartphone overuse [12].…”

Objective: This research investigated the effects of simple visual imagery and mental rotation imagery on neural activity of adults who are at high risk of smart phone addiction by measuring their electroencephalography (EEG). Design: Cross-sectional study. Methods: Thirty people with a high risk of smart phone addiction was selected and then were evaluated for their neural activation patterns using EEG after reminding them about simple visual imagery and mental rotation imagery. A simple visual image was applied for 20 seconds using a smartphone. This was followed by a resting period of 20 seconds. Mental rotation imagery was applied for 20 seconds. During mental rotation imagery, the rotational angle was selected at random. We compared activation patterns according to the analyzed EEG with hemisphere reminding them about imagery. Results: On the EEG, theta rhythm from the left hemisphere parietal area increased when the subjects were reminded of mental rotation imagery, and sensorimotor rhythm from close to the left hemisphere area increased when the subjects were reminded of simple visual imagery. Conclusions: Neural activation from the left hemisphere occurs for motor imagery in adults who are at high risk of smart phone addiction. These results identify a neural mechanism of adults who a have high risk of smart phone addiction, which may provide contribute to the development of motor rehabilitation for smartphone users.

Dependency on Smartphone Use and its Association with Anxiety in Korea

Abstract: Among this group of university students in South Korea, smartphone dependency appeared to be associated with increased anxiety. Standards for smartphone use might help prevent deleterious health effects.
