Résumé
Background: the relationship between the sleep pattern and the academic performance among medical students is not well addressed in the literature. This study aimed to assess the association between sleep pattern and academic performance among medical students at King Saud Bin Abdulaziz University for Medical Sciences
Methods: this descriptive cross-sectional study was conducted on male medical students at King Saud Bin Abdulaziz University for Health Sciences at Riyadh, Saudi Arabia. They were included and the Exclusion criteria were students in Basic sciences phase and preparatory phase. The questionnaire was obtained from Groninger Sleep Quality Questionnaire and it was distributed through official university email. Responding rate was 25.7%[n=166] out of 645 students whom were included. SPSS was used to manage and analyze the data
Results: the majority of students [27.1%] who showed adequate sleep had GPA of between 3.5 and 4.49 which was referred to good academic performance. 0.6% of those who showed adequate sleep score less than 2.5 GPA. On the other hand, 22.9% of the students showed inadequate sleep score GPA of between 3.5 and 4.49
Conclusions: our results showed that sleep quantity and quality doesn't play significant roles in academic performance of students. Nevertheless, students should adopt a healthy sleep pattern
Résumé
Background: Musculoskeletal disorders [MSDs] are common among EMS personnel throughout the world
Objective: The aim of the study was to determine how common the [MSD] among the EMS personnel and its associated factors such as smoking, BMI and place of work [field-workers and hospital-workers] in Saudi Arabia, Riyadh
Methods: Cross-sectional study to measure the prevalence of [MSD] among the EMS personnel. The Nordic Musculoskeletal Disorders Questionnaires were distributed to collect the data from SRCA and tertiary hospitals. The required sample size was 180 from each group. Chi-square test was used to assess the association between the MSDs and categorical date
Results: Questionnaires of 360 participants were completed and analyzed. The most prevalent site affected was the lower back [60.3%] followed by knees [41.4%], neck [40.3%] and upper back [40%]; the least frequent disorder was that of hip/thigh [10.3%]. Hence, [37.2%] of the paramedics suffer low back pain during their duty. Also, BMI results have shown a prevalence of obesity [19.2%], overweight [41.4%] and only [36.1%] fall within the normal range of BMI and increased BMI is highly associated to lower back [p=0.009]. Furthermore, smokers number were very high [65%] and it was associated with MSD with [P<0.05] in the lower back and knees. The result showed that there was no significant difference between work places
Conclusion: The very high prevalence of MSDs was found among paramedics. It is suggested that paramedics have to be engaged in programs at their work place. Such as, exercise, improve the manual handling techniques and encourage smoke cessation
