Introduction Online learning is the educational format adopted by schools and universities during the coronavirus disease 2019 (COVID-19) pandemic. It comprises Internet-based learning, computer-based learning, virtual classrooms, and digital collaborations. This study aims to assess digital eye strain (DES) among children attending online classes in the Qassim region, Saudi Arabia. Materials and methods This is a cross-sectional study conducted among children aged 3 to 18 years old in the Qassim region, Saudi Arabia. We sent out a self-administered questionnaire to parents of the targeted children by using social media, such as WhatsApp (Meta Platforms, Inc., Menlo Park, California, United States), Telegram (Telegram FZ LLC, Dubai), and Twitter (Twitter, Inc., San Francisco, California, United States). The questionnaire included questions on socio-demographic profile, smart devices being used, frequency of devices used per day before and during the lockdown, and DES. Results A total of 547 children were involved (50.3% males vs. 49.7% females). During online classes, the most commonly used device was tablets (51.2%). A significant increase was noticed in the use of devices during the COVID-19-related lockdown among children (p0.001). The prevalence of DES-positive symptoms was 69.8%. The presence of DES symptoms was associated with age group (p=0.003), school level (p=0.040), device preferred for online classes (p=0.001), number of hours spent attending online classes (p=0.010), and number of hours spent using an electronic device during the lockdown (p0.001). Conclusion Our study underlines a higher prevalence rate of DES among children during this time of the COVID-19 pandemic. Children who used a digital device for more than five hours during the lockdown had a greater risk of having DES than the rest.

Introduction Work-related musculoskeletal disorders (WMSD) are defined as conditions that the environment contributes significantly to / worsens due to work conditions. WMSD comes second in the source of disability in both developed and developing countries. The aim of this study is to measure the prevalence, patterns, and risk factors of musculoskeletal pain disorders among teachers in the Qassim region, Saudi Arabia. Methods A cross-sectional study was conducted among school teachers in the Qassim region, Saudi Arabia. A validated online Arabic questionnaire was distributed among teachers living in the Qassim region through multiple social networking applications like Facebook, WhatsApp, and Telegram. The questionnaire consisted of Socio-demographic characteristics, the Nordic Musculoskeletal Questionnaire, and a modified version of the Orebro Musculoskeletal Pain Screening questionnaire. Results A total of 503 school teachers were recruited. The proportion of musculoskeletal pain was 91%, and the most common site of pain was back (74.4%), followed by the shoulder (57.5%) and leg (51.5%). The proportion of disabling pain was (80.1%) while the rest was non-disabling pain (19.9%). In the multiple regression model, the predictors of increased disabling pain were back pain, leg pain, neck pain, and those with 51-70 kg weight. In comparison, the predictors of decreased disabling pain were having more than 7 hours of sleep and those with 20-30 classes per week. Conclusion Musculoskeletal pain disorders were widely prevalent among school teachers in the Qassim region, Saudi Arabia. Most teachers considered pain as disabling, which negatively affected their attendance. The back, shoulder, and neck were the most painful sites associated with disabling pain.

Introduction Child abuse can include physical abuse, psychological abuse, sexual assault, neglect, or failure to meet the child's basic needs. It can lead to major psychosocial problems resulting in long-lasting consequences for the child. Objective This study aimed to assess the knowledge and attitude (KA) of primary healthcare physicians and interns regarding child abuse in Al Qassim, Saudi Arabia. Materials and methods This multicenter, cross-sectional study was conducted among primary healthcare physicians and interns in the Qassim region, Saudi Arabia, from July to October 2020. A self-administered questionnaire was distributed among the targeted physicians using either an online platform or face-to-face interviews. The questionnaire was devised from the pre-tested literature and formal discussions with experts. A total of 292 primary healthcare physicians and interns participated in our study. A consent form and brief details of the study were given ahead of the recruitment. Data were tabulated in a Microsoft Excel spreadsheet (Microsoft Corporation, Redmond, WA); a separate codebook was prepared with a description of the variables and corresponding codes, and all statistical analyses were performed using IBM SPSS Statistics for Windows, Version 21.0 (IBM Corp., Armonk, NY). Results A total of 292 respondents were involved in the study. Among them, 45% (n=131) were medical interns, 39.4% (n=115) were residents, and the rest were either specialists (n=34; 11.6%) or consultants (n=12; 4.1%). Among the respondents, the KA level was found to be moderate, high, and low in 68.8%, 28.4%, and 2.7%, respectively. The overall mean KA score was 81.1 [standard deviation (SD): 9.56] out of a possible 115 points. Factors associated with high KA were age (>30 years), non-Saudi nationality, having children, and having studied outside Saudi Arabia; The only factor significantly associated with low levels of KA was being a pediatrician (p
