Background: Low back pain (LBP) is a leading cause of occupational disability worldwide, particularly among manual laborers such as bricklayers who are frequently exposed to physical stressors like lifting, bending, and awkward postures. Despite its impact on productivity and health, there is limited local data on LBP among bricklayers in Egor Local Government Area (LGA) of Edo State, Nigeria. Methods: A descriptive cross-sectional survey was conducted among 222 active bricklayers in Egor LGA using a structured, validated questionnaire adapted from the Standardized Nordic Questionnaire. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 26. Descriptive statistics summarized prevalence data, while Chi-square tests and logistic regression were applied to determine associations between LBP and occupational/personal factors at a significance level of p < 0.05. Results: Findings revealed that the 12-month prevalence of LBP among bricklayers was high. Significant occupational factors associated with LBP included prolonged bending, lifting heavy materials, poor posture, and long working hours. Personal factors such as age, smoking, and elevated body mass index (BMI) also contributed significantly. The majority of affected workers reported recurrent pain episodes that interfered with daily work performance and overall well-being. Conclusion: The prevalence of LBP among bricklayers in Egor LGA is substantial and largely attributable to preventable ergonomic and behavioral factors. Strengthening ergonomic education, enforcing rest breaks, and promoting the use of mechanical aids can reduce the burden of LBP and enhance worker productivity.

Background: Knee injuries are among the most prevalent musculoskeletal problems affecting student- athletes, often resulting in pain, impaired performance, and limited participation. Despite the growing engagement of university students in organized sports, limited research has addressed the prevalence and contributing factors of knee injuries within Nigerian university settings. Aim: This study aimed to determine the prevalence, types, risk factors, and socio-demographic correlates of knee-related injuries among student-athletes at the University of Benin. Methods: A descriptive cross-sectional research design was employed. A total of 207 student-athletes from various faculties of the University of Benin participated in the study. Data were collected using a structured, self-administered questionnaire assessing socio-demographic characteristics, types of knee injuries, associated risk factors, and management strategies. Descriptive statistics summarized the data, while inferential analysis using Chi-square tests assessed associations between variables at a 0.05 significance level. Results: Findings revealed a high prevalence of knee injuries, with 185 respondents (89.4%) reporting a history of knee injury. The most common types were fractures (45.4%), ligament tears (24.9%), and meniscus injuries (15.7%). Injuries were mostly sports-related (29.7%) or caused by sudden movement (25.9%), and the left knee was the most frequently affected (36.8%). More than half of the injured athletes (51.9%) sought treatment—mainly through medication and physiotherapy—while 39.5% reported persistent pain during activity. iv Statistical analysis showed no significant relationship between intrinsic risk factors (flexibility, previous lower limb injury, and muscle imbalance) or extrinsic risk factors (training intensity, surface type, warm-up routine, and use of protective gear) and knee injury occurrence (p > 0.05). However, sport type was significantly associated with knee injury prevalence (χ² = 17.12, p = 0.029), with football and volleyball athletes being more affected. Age, gender, body mass index (BMI), and level of study were not significantly related to knee injury prevalence. Conclusion: Knee injuries are highly prevalent among student-athletes at the University of Benin, primarily associated with the type of sport rather than intrinsic, extrinsic, or demographic variables. There is a critical need for improved injury prevention programs, enhanced warm- up and training protocols, better facility maintenance, and accessible physiotherapy services to reduce the burden and recurrence of knee injuries in university sports settings

This study evaluated the operational and health risk factors associated with municipal solid waste scavenging in two privately-operated municipal Solid waste dumpsites in Benin City, Edo State. A well- structured questionnaire was administered to 100 randomly selected scavengers; the questionnaire covered demographics, personal details, and information on the types and frequencies of health hazards encountered by waste scavengers, providing insights into the challenges they face. The findings revealed significant health risks including injuries, respiratory problems, and gastrointestinal illnesses, highlighting the need for interventions to improve the safety and well-being of the scavenging operations. Furthermore, they also face several operational risks due largely to the lack of use of personal protection equipment, resulting in cuts, respiratory issues, and gastrointestinal illnesses, with a notable proportion experiencing frequent headaches and a high prevalence of malaria. We recommend that the operators of the dumpsites should be regulated by the Edo State Waste Management Board, with strict guidelines and punitive measures put in place for lack of compliance. On the part of the dumpsite operators, they should provide all necessary personal protection equipment and enforce their use as a standard operating procedure. Furthermore, first aid equipment for staff, drinking water and bathrooms with soap and water for their sanitation should be provided.

This study investigated cardiovascular disease (CVD) presentations, risk factors, and treatment outcomes among 102 older adults receiving care at the University of Benin Teaching Hospital, Edo State. A descriptive cross-sectional design with structured questionnaires was used. The mean age of respondents was 66.5 years; 52.9% were female and 47.1% male. Hypertension (26.5%) and cardiac structure/function disorders (26.5%) were the most prevalent diagnoses. The most reported CVD presentations were chest pain (73.5%), rapid fatigue (83.3%), irregular heartbeat (100%), weakness/lightheadedness (83.4%), and shortness of breath during activities (79.4%). Awareness of risk factors was high, with over 90% acknowledging hypertension, obesity, diabetes, poor diet, physical inactivity, and stress as contributors to CVD. However, only 73.3% recognized gender differences in disease patterns. Perceptions of gender disparities in treatment were generally low, though 56.6% agreed that differences in care may affect survival, and 90.1% emphasized the need for gender equity in treatment. Chi-square analysis revealed no significant association between gender and CVD presentations (p=0.077) or treatment outcomes (p=0.194), but a significant relationship existed between gender and risk factor awareness (p=0.024). The findings highlight the importance of sustained health education and gender-sensitive strategies to improve CVD management in older adults.
