PurposeThe aim of the current study was to investigate the extent of smartphone use, possible correlation with neck pain and/or psychological impairment in office workers.MethodA convenience sample of 1,602 office workers who were using smartphone for prolonged periods (≥ 4 years) participated in a cross-sectional report of a cohort study, assessing demographic, abnormal symptoms of pain in the neck, physical activity, and psychological behavior characteristics. Participants were assessed using a short version of the Smartphone Addiction Scale (SAS-SV), Depression, Anxiety and Stress Scales (DASS-42) questionnaire, as well as International Physical Activity Questionnaire-Short Form (IPAQ-SF). Multiple logistic regression model was conducted to evaluate the adjusted effect of smartphone overuse on nuchal symptoms.ResultsThe prevalence of neck pain among the office workers was 30.1%. Significantly more female (33.3% vs. 24.5%) and younger (42.2 vs. 43.2 years) employees reported to have neck pain. Overall in 326 (20.3%, 95% CI: 18.4%-22.4%) of studied subjects had, SAS score ≥ 31 and ≥ 33 for male and females, respectively, and so smartphone overuse (SO) was diagnosed. The results of multiple logistic regression model revealed that those with SO were approximately 6 times more likely to have neck pain (95% CI: 4.44-8.09, P < 0.001).ConclusionsSmartphone overuse in office workers significantly increases the chance of neck pain by 6 times. Hence SO has been associated with, not only somatic complaints, but also psychological distress such as anxiety, stress, and depression. This may necessitate adherence to neck-school, when smartphone use is associated with neck pain.
