The impact of smartphone addiction on attention control and sleep in Egypt—an online survey

The widespread use of smartphones makes it imperative for researchers to study the adverse effect of smartphone addiction. We aimed to study the risk factors of smartphone addiction, insomnia, and attention deficit among smartphone users among a sample of Egyptian adolescents and adults. An online survey was disseminated among Egyptian social media groups. Participants were requested to complete Smartphone Addiction Scale-Short Version (SAS-SV), Insomnia Severity Index (ISI) scale, and attention control scale (ACS). Two-thousand seven-hundred sixteen responded to our survey with a mean age of 31.4 ± 10.3 years. Smartphone addiction was documented in 2386 (87.8%) participants, with a median daily time for smartphone use of 5 h (IQR: 3–7). A significant association was found between smartphone addiction and younger age, higher educational levels, and urban residency (unadjusted or adjusted). Binary logistic regression analysis showed that the only factor affecting the probability of moderate to severe insomnia was the higher SAS-SV score, either unadjusted (OR = 1.1, 95% CI: 1.08–1.1) or adjusted (OR = 1.09, 95% CI: 1.08–1.11). Multiple linear regression analysis showed that higher scores on SAS-SV (P < 0.001) and ISI (P < 0.001), being female (P < 0.001), and being of rural residency (P = 0.025) were associated with lower total scores on ACS. On the other hand, older age (P < 0.001) and longer intervals between smartphone cessation and bedtime (P = 0.004) were found to increase the attention score. Smartphone addiction is prevalent in Egypt, which deserves special concern as it may have negative consequences such as insomnia and poor attention control, particularly in younger age groups.
