Introduction: There is growing concern over the impact that social media use by university students could have on their academic performance due to its effect on sleep. The study assessed the influence of social media use, sleep quality and academic performance of students of the School of Basic Medical Sciences of the University of Benin. Methods: A descriptive survey research design was utilized in the study. Stratified random sampling technique was adopted for selecting 344 undergraduates. The data collection instrument included a structured questionnaire, which contained SMUS, PSQI and academic performance measure (CGPA). Descriptive analysis of participants' profile was undertaken using simple statistics and Pearson correlation was used to test the hypotheses at 0.05 alpha level. Results: Amongst all the respondents, 60.5% were female. The average SMUS was 10.09 ± 1.72, implying high levels of social media engagement, while the mean PSQI score was 7.73 ± 4.14, depicting fair to poor sleep quality. With respect to academic performance, 55.8% of the respondents scored between 3.50 and 4.49 CGPA. A strong negative correlation between social media usage and academic performance (r = -0.244, p < 0.001) was found. There was, however, no significant association between social media usage and sleep quality (p = 0.813) nor between sleep quality and academic performance (p = 0.391). Conclusion: This study reveals that social media usage adversely impacts academic performance, and sleep quality does not act as a mediator in this relationship. The students are advised to adopt healthy social media practices and concentrate on academics. The institution should consider raising awareness about this issue through appropriate digital literacy programs. iv Keywords: Social media usage, sleep quality, academic performance, undergraduates, Basic Medical Sciences, University of Benin.

Background: Stroke remains one of the leading causes of death and long-term disability worldwide, with an increasing incidence in low- and middle-income countries such as Nigeria. Early recognition and appropriate response to stroke symptoms are critical to improving outcomes. Medical students, as future healthcare providers, play a vital role in promoting stroke awareness and emergency response. Objective: This study assessed the level of knowledge of stroke, its risk factors, warning signs, and appropriate emergency responses among clinical undergraduate students in the School of Basic Medical Sciences (SBMS), University of Benin. Methods: A descriptive cross-sectional survey design was employed. A structured, self- administered questionnaire was distributed to 322 clinical undergraduates selected through stratified random sampling. Data were analyzed using descriptive and inferential statistics, including frequency, percentage, and chi-square tests at a 0.05 significance level. Results: Findings revealed a generally high level of stroke awareness among respondents. Most participants (94.1%) correctly identified the brain as the organ affected by stroke, and 98.4% recognized that stroke is preventable. Hypertension (77.0%), old age (73.3%), and diabetes were the most frequently identified risk factors. Paralysis of one side of the body (78.6%) and speech difficulty (77.3%) were the most recognized warning signs. A significant association existed between level of study and knowledge of stroke risk factors (p = 0.035) and between gender and planned response to stroke events (p = 0.02). Conclusion: Clinical undergraduates of the University of Benin demonstrated commendable theoretical knowledge of stroke, its risk factors, and warning signs. However, gaps remain in the understanding of lifestyle-related risk factors and practical emergency response.
