Internet Usage Profile of Medical Students and Effects of Internet Addiction on Sagittal Balance

SDÜ Tıp Fakültesi Dergisi, Sep 2019

Objective: The risk of internet addiction increases as the time of internet usage increases. Long-term internet usage may effect the posture of the person. This may cause the change of the gravity center and may effect the segmental degeneration. Methods: In Suleyman Demirel University, 168 medical students had internet addiction scale. The scores ≥81 accepted as internet addicted. Equal number of adolescents who got the diagnosis of internet addicted and not had cervical/lumbar x-ray graphics. Sagittal alignments were evaluated by using Cobb’s method. Probable internet addicted descriptive analysis, TwoStep Cluster Analysis, ANOVA, Independent Samples t-Test, Product-Moment Correlation, Mann-Whitney U analysis were used. Results: Nine(5,4%) students were internet addicted. There was a significant difference between internet usage habits and internet addiction scores, but the highest difference was found between “intermittent+long time usage” and “total usage in once”. There was only a negative(r = -.341) and significant relation(p= .021) between internet addiction and lumbar Cobb angle. As the score of internet usage increases, value of lumbar Cobb angle decreases. Only lumbar Cobb angle values were significantly different(p= .030) for devices used for internet access. According to the Rank values, students’ lumbar Cobb angle using laptop as internet access device(13,07) were lower than the students’ using cell phone or pads(21,07). Conclusion: Being in the same and unsuited anatomical position while using internet for a long time may cause changes in the sagittal alignment. Loadings and stresses on spinal structures influence the spinal morphology and cause the occurrence of disc degeneration.

Öz Amaç İnternet kullanımının artması ile internet bağımlılığı riski de artmaktadır. Uzun süreli internet kullanımı kişinin duruşunu etkileyebilmektedir. Bu durum, ağırlık merkezinin değişmesine ve segmental dejenerasyona neden olabilmektedir. Bu calismada, gençlerde internet kullanımının postur üzerindeki etkilerinin ortaya konması amaclanmıstır. Gereç ve Yöntem Bu çalışma kesitsel analitik tipte bir çalışmadır. Süleyman Demirel Üniversitesi’nde 168 tıp öğrencisine internet bağımlılığı skalası uygulandı. ≥81 skoru olanlar internet bağımlı olarak kabul edildi. Internet bağımlılığı tanısı almış ve almamış eşit sayıda adolesandan servikal / lomber direkt grafiler alındı. Sagital dizilim Cobb metodu ile değerlendirildi. Olası internet bağımlı tanımlayıcı analiz, İki basamak küme analizi, ANOVA, bağımsız örnekleme t-testi, Pearson korelasyonu, Mann-Whitney U analizi kullanıldı. Bulgular Dokuz öğrenci (%5,4) internet bağımlıydı. İnternet kullanım alışkanlıkları ile internet bağımlılık skoru arasında anlamlı fark tespit edildi, ancak en yüksek fark “aralıklı+uzun süre kullanan” ve “tek seferde total kullanan” grup arasında bulundu. Sadece internet bağımlılığı ve lomber Cobb açısı arasında negatif (r = -.341) ve anlamlı bir ilişki (p= .021) vardı. İnternet kullanım skoru arttıkça, lomber Cobb açı değeri azalmaktaydı. İnternet kullanımındaki farklı cihazlar için lomber Cobb açı değeri belirgin olarak farklıydı(p= .030). Rank değerlerine gore, laptop kullanan öğrencilerin lomber Cobb açı değeri(13,07), cep telefonu veya tablet kullananlardan(21,07) daha düşüktü. Sonuç Uzun süreli internet kullanımında aynı ve uygun olmayan anatomik pozisyonda durmak sagittal dizilimde değişikliklere neden olabilir. Spinal yapılar üzerindeki yüklenmeler ve stres spinal morfolojiyi etkiler ve disk dejenerasyonlarının ortaya çıkmasına neden olur. Erken yaşlarda ortaya çıkan bu dejenerasyonlar hastanın yasam kalitesini olumsuz yönde etkileyecektir. Anahtar Kelimeler: İnternet bağımlılığı, sagittal dizilim, cobb açısı, sagittal vertikal aks, sagittal denge Abstract Objective The risk of internet addiction increases as the time of internet usage increases.

Material and Methods In Suleyman Demirel University, 168 medical students had internet addiction scale. The scores ≥81 accepted as internet addicted. Equal number of adolescents who got the diagnosis of internet addicted and not had cervical/lumbar x-ray graphics. Sagittal alignments were evaluated by using Cobb’s method. Probable internet addicted descriptive analysis, TwoStep Cluster Analysis, ANOVA, Independent Samples t-Test, Product-Moment Correlation, Mann-Whitney U analysis were used. Results Nine(5,4%) students were internet addicted. There was a significant difference between internet usage habits and internet addiction scores, but the highest difference was found between “intermittent+long time Introductıon Internet usage is increasing rapidly in the developing world. Since it becomes the biggest library of the world, it is easier to achieve to the scientific resources within minutes (1). As the average time spending for internet can be a risk for addiction, preventive measures come into prominence. Postural deformity, that may occur with excessive usage of computer and internet with a loss of sense of time can improve degenerative disorders. Sagittal alignment of the spine is important as it affects the distributions of the load on intervertebral discs, and normal lordotic alignment of cervical and lumbar spine is important for effective motion and function. Impairment of the normal lordosis may cause a degeneration of this functional unit, that causes spinal morbidities such as neck and back pain (2,3). The aim of this study was to investigate the internet usage profile of medical students, and the effect of internet usage on cervical- lumbar sagittal alignment, and to reveal the relation of psychological and physical effects of internet. Material and Methods First, second, and third–year 168 medical students of Suleyman Demirel University, School of Medicine, Turkey were enrolled in this study. A self-administered schedule was used to all students. Permission for t 249 Internet Usage Profile and Sagittal Balance usage” and “total usage in once”. There was only a negative(r = -.341) and significant relation(p= .021) between internet addiction and lumbar Cobb angle. As the score of internet usage increases, value of lumbar Cobb angle decreases. Only lumbar Cobb angle values were significantly different(p= .030) for devices used for internet access. According to the Rank values, students’ lumbar Cobb angle using laptop as internet access device(13,07) were lower than the students’ using cell phone or pads(21,07).

Loadings and stresses on spinal structures influence the spinal morphology and cause the occurrence of disc degeneration. Keywords: Internet addiction, sagittal alignment, Cobb angle, sagittal vertical axis, sagittal balance. the study was obtained from the Suleyman Demirel University School of Medicine Scientific Research Projects Advisory Board (approval of the local ethics committee: date:07.03.2012; decision no:11), and the students that consent was obtained for radiographic studies evaluated for radiological evaluation. After self-administered schedule applied to all of the 168 students, they were diagnosed as internet addicted or possible internet addicted. Then they were referred for cervica (...truncated)
