Smartphone addiction and its association with hypertension and quality of sleep among medical students of Northern Border University, Arar, Saudi Arabia

OBJECTIVES: To observe the smartphone addiction's prevalence and its relation to hypertension and sleep quality. METHODS: <0.05 was viewed as statistically significant. RESULTS: Prevalence rate of smartphone addiction was 36% (39.8% in men and 30.5% in women) and prevalence rate of hypertension was 35.5% (42.4% in men and 25.6% in women). Hypertension showed a significant positive relationship with smartphone addiction (odds ratio OR=2.12, 95% confidence interval CI =1.034-4.36), poor sleep quality (OR=3.54, 95% CI=1.73-7.22), and obesity (OR=3.03, 95% CI=1.09-8.42). CONCLUSION: Smartphone addiction has been demonstrated to have a high prevalence among medical undergraduates and has been associated significantly with elevated blood pressure.
