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

Abstract

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.

Tıp Öğrencilerinin İnternet Kullanım Profili ve İnternet Bağımlılığının Sagital Dengeye Etkisi

Abstract

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.

Metod: Süleyman Demirel Üniversitesi’nde 168 tıp öğrencisine internet bağımlılığı skalası uygulandı. ≥81 skoru olanlar ınternet bağımlı olarak kabul edildi. Internet bağımlılığı tanısı almış ve almamış eşit sayıda adolesandan servikal / lomber dırekt grafiler alındı. Sagital dizilim Cobb metodu ile değerlendirildi. Olası internet bağımlı tanımlayıcı analiz, İkiBasamak Küme analizi, ANOVA, bağımsız örnekleme t-testi,ürün-önem korelasyonu, Mann-Whitney U analizi kullanıldı.

Sonuçlar: Dokuz öğrenci(%5,4)  internet bağımlı idi. İnternet kullanım alışkanlıkları ile internet bağımlılık skoru arasında anlamlı fark tespit edildi, ancak en yüksek fark “aralıklı+uzun sure kullanan”  ve “tek seferde total kullanan” grup arasında bulundu. Sadece internet bağımlılığı ve lomber Cobb açısı arasında negatif (r = -.341) ve belirgin 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 sureli 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.
