Investigation of Screen Time Inclination and the Accompanying Visual and Musculoskeletal Discomfort in Young Smartphone Users

The purpose of this study is to investigate the screen time inclination and its accompanying visual and musculoskeletal discomfort in young smartphone users. Thirty-one smartphone users aged between 20 - 30 years old were recruited through convenient sampling. The screen time patterns were recorded daily for a week and documented using Action Dash on Google Play Store according to the times of the day (morning, afternoon evening and night). Accompanying visual and musculoskeletal symptoms were examined through a self-reporting questionnaire survey. The questions used in the questionnaire were adapted and modified from the Asthenopia Questionnaire and Nordic Musculoskeletal Questionnaire. Results showed that young smartphone users spent approximately 30 % of their time on screen and were relatively similar for different times of the day. Daily screen time was approximately 7.36 ± 1.74 h. Most users engaged in WhatsApp (74 %), followed by YouTube (68 %), Instagram (65 %) and Twitter (39 %). Tired eyes were reported by all smartphone users. A positive correlation was only found between weekly screen time and eye strain (p < 0.05). All musculoskeletal symptoms were self-reported by young smartphone users in our study but anatomical locations varied in percentages. Neck pain was the most significant musculoskeletal symptom associated with screen time (OR = 4.80, 95 % CI: 0.95 - 24.14, p < 0.05). Every smartphone user reported at least 1 type of visual symptom. All smartphone users reported tired eyes. In conclusion, our results showed that smartphone users spent one third of their time daily on-screen and mostly on social media. Tired eyes and neck pain were the most common accompanying symptoms. Visuo-skeletal symptoms are common among young and healthy smartphone users. Our findings advocate that future strategic plans to address digital related health problems from the perspective of health education, promotion and protection should be inclusive of youth. HIGHLIGHTS Excessive screen time is a public health concern Adverse health implications have been linked to excessive electronic usage Smartphone users spend one-third of their time daily on-screen and mostly on social media Visuo-skeletal symptoms are common among young and healthy smartphone users Tired eyes and neck pain are the most common accompanying symptoms GRAPHICAL ABSTRACT
