Introduction: The consumption of psychoactive substance remains a significant global health challenge, particularly among young adults in tertiary institutions. Medical students occupy a uniquely precarious position due to the rigorous cognitive and emotional demands of their training. In Nigeria, national drug use prevalence has surged beyond the global average, with synthetic drugs and new psychoactive substances becoming increasingly accessible in southern urban centers like Benin City. Objectives: The aim of the study was to assess the prevalence, pattern and perceived factors associated with substance use among medical students at the University of Benin. Methodology: A descriptive cross-sectional study was conducted among undergraduate medical students (200-level – 600-level) at the University of Benin. A systematic random sampling technique was employed to select the sample size. Data were collected using a structured, self-administered questionnaire adapted from the WHO Student Drug Use Questionnaire (SDUQ) and the General Health Questionnaire (GHQ-12). Analysis was performed using IBM SPSS version 27. Results: A total of 298 respondents participated (100% response rate). Alcohol was the most prevalent substance, with a lifetime usage of 63.4% and a past 30-day prevalence of 5.8%. Tobacco/nicotine had a lifetime prevalence of 14.1%, while current opioid use was reported by 2.7% of respondents. Significant associations were found between alcohol use and academic level (highest in 300-level), monthly allowance, and marital status. Furthermore, alcohol and stimulants were significantly associated with psychological distress (p= 0.024 and p= 0.036, respectively), with 82.0% of current stimulant users exhibiting distress. Conclusion: Substance use is highly prevalent among medical students at the University of Benin, primarily serving as a functional coping mechanism to manage intense academic workloads and systemic rigors rather than recreational purposes. The findings highlight a critical need for institutions to transition from punitive measures towards a wellness-oriented framework, incorporating confidential counselling and curriculum restructuring to mitigate student stress and promote healthier learning environments.

Introduction: Workplace violence (WPV) against healthcare workers is a major occupational and public health concern globally, with significant consequences on the safety, psychological well-being, job satisfaction, and productivity of healthcare personnel. Objective: This study assessed the prevalence, causes, and effects of workplace violence against healthcare workers in the University of Benin Health Services department, Benin City, Edo State. Methodology: A descriptive cross-sectional study design was adopted among healthcare workers in the University of Benin Health Services Department. A total population survey method was used, and data are collected using a structured questionnaire adapted from the International Labour Organization (ILO), International Council of Nurses (ICN), World Health Organization (WHO), and Public Services International (PSI) workplace violence research instrument, administered through both self-administered and interviewer-administered approaches. One hundred and sixty-five completed questionnaires are analyzed using IBM SPSS version 27.0, with descriptive and inferential statistics performed at a 95% confidence interval and a significance level of p < 0.05. Results: The lifetime prevalence of workplace violence among respondents was 35.2%, while 21.2% and 33.3% report experiencing physical violence and verbal abuse respectively within the six months preceding the study. Patients or clients constitute the major perpetrators of both physical violence (72.7%) and verbal abuse (72.7%). Professional category shows a statistically significant association with workplace violence (p = 0.003), with clinical staff experiencing a higher prevalence than non-clinical staff. The major perceived causes of workplace violence are the non-availability of doctors or nurses on call duty (72.7%) and the aggressive personality of perpetrators (70.9%). Post-traumatic stress disorder (63.1%) and loss of job satisfaction (53.3%) are the most commonly reported effects of workplace violence among respondents. Conclusion: Workplace violence occurs among healthcare workers in the University of Benin Health Services Department, with verbal abuse being more commonly reported than physical violence. Non-availability of healthcare workers on call duty and aggressive behaviour of perpetrators emerge as the major perceived causes, while post-traumatic stress disorder and loss of job satisfaction constitute the major effects. Strengthened institutional policies, improved staffing, and supportive interventions are needed to reduce workplace violence and improve healthcare worker safety.

Introduction: Household air pollution (HAP) remains a major public health concern in low- and middle-income countries, particularly in Nigeria where biomass fuel use is still common. Under-five children are especially vulnerable due to their developing respiratory systems and increased exposure within household environments. Despite existing global data, there is limited community-specific evidence in peri-urban areas such as Ekosodin, Benin City. Objectives: This study aimed to determine the prevalence of household air pollution and respiratory symptoms among under-five children in Ekosodin, Benin City, Edo State. It also sought to identify common sources of HAP and assess the association between exposure and respiratory symptoms. Methodology: A descriptive cross-sectional study was conducted among caregivers of under￾five children using a multistage sampling technique. A minimum sample size of 298 was calculated, with 280 respondents participating. Data were collected using a structured interviewer-administered questionnaire and analyzed using IBM SPSS version 27. Chi-square test and logistic regression were used to assess associations at a significance level of p < 0.05. Results: The majority of households used cleaner fuels, with gas (61.1%) and electricity (14.6%) being the most common, although some still used firewood (12.9%) and kerosene (7.5%). Most households had ventilation (94.6%), but only 18.6% had smoke outlets. Cough was the most prevalent respiratory symptom (31.4%), while wheezing (8.6%) and shortness of breath (3.2%) were less common. Diagnosed respiratory illnesses such as pneumonia (2.9%) and bronchitis (2.9%) were relatively low. Significant associations were found between respiratory symptoms and use of unclean fuels (p = 0.018), child proximity to cooking areas (p < 0.001), indoor pollution sources such as mosquito coils (p = 0.001), place of cooking (p < 0.001), and indoor tobacco smoking (p = 0.002). xi Conclusion: Despite the predominant use of cleaner fuels, household air pollution exposure remains prevalent due to other contributing factors such as cooking location, poor smoke outlet availability, and indoor pollution sources. These factors significantly influence the occurrence of respiratory symptoms among under-five children. Interventions should focus on improving household environmental practices alongside promoting clean energy use

Introduction: Occupational hazards remain a major public health concern, particularly in manufacturing industries where workers are exposed to physical, chemical, ergonomic, and psychosocial risks. Despite existing global and national regulations aimed at ensuring workplace safety, such as those guiding occupational health practices, these hazards persist, especially in developing countries due to poor compliance and underreporting, thus this study assessed occupational health hazards and safety practices among workers of Seven-Up Bottling Company, Benin City, Edo State. Objective: This study was conducted to assess occupational hazards and safety practices among workers in Seven-Up Bottling Company, Benin City, identify the common occupational health hazards present and factors predisposing workers to these hazards, with the goal of guiding targeted prevention and occupational health promotion to reduce workplace risks. Methodology: A descriptive cross-sectional study was conducted among 105 workers selected using a systematic sampling technique. Data were collected using a structured interviewer- administered questionnaire and analysed using IBM SPSS version 26. Descriptive statistics such as frequencies, percentages, means, and standard deviations were used to summarize data, while Chi- square test and binary logistic regression were used to determine associations and predictors at a 5% level of significance. Results: The mean age of respondents was 32.7 ± 8.1 years. Most respondents were males, 71 (67.6%), and were between 20–29 years, 45 (42.9%). Common occupational hazards identified included psychological stress, awkward posture, repetitive movements, noise exposure, slippery floors, moving machinery without adequate guards, and glass bottle explosions. More than half of the respondents, 58 (55.2%), demonstrated poor safety practices, while 47 (44.8%) had good safety practices. Department/unit was significantly associated with the level of safety practice (p < 0.001). Additionally, 42 (40.0%) of respondents sustained work-related injuries in the last 12 months. Among those injured, cuts and lacerations from broken glass or metal were the most common

Environmental sanitation remains a major public health concern in market environments, particularly in developing countries where overcrowding, poor waste disposal, and inadequate sanitation facilities are common. This study assessed the knowledge, practices, and barriers to environmental sanitation among market women in Uselu Market.

Objective: This study was conducted to assess the environmental sanitation practices among market women in Uselu market and identify the factors influencing these practices with the aim of providing evidence-based recommendations for improving sanitation standards, reducing environmental health risks, and preventing sanitation-related diseases within market settings.
Methodology: A descriptive cross-sectional study design was adopted among 330 market women selected using a multistage sampling technique. Data were collected using a structured interviewer-administered questionnaire and analysed using Statistical Package for the Social Sciences (SPSS) version 27. Descriptive statistics such as frequencies and percentages were used to summarize data, while Chi-square test was used to determine associations between variables at a 5% level of significance.
Results: Findings revealed that the majority of respondents had good knowledge of environmental sanitation, with 64.5% correctly defining environmental sanitation and over 90% demonstrating awareness of disease prevention, waste management, and environmental cleanliness. Environmental sanitation practices were generally good, as 98.8% cleaned their stalls daily, 93.6% used designated waste bins, and 96.7% participated in sanitation exercises. However, poor practices were observed in waste segregation, where 73.3% never separated waste before disposal, and reporting of sanitation problems, where 34.8% never reported sanitation issues. Major barriers identified included financial constraints (16.7%), lack of waste bins (16.1%), and irregular waste collection (9.1%). Ethnicity was significantly associated with knowledge of environmental sanitation practices (p = 0.005), while religion was significantly associated with sanitation practices (p = 0.021).

Conclusion: The study concluded that although market women demonstrated good knowledge and relatively good sanitation practices, important gaps remain due to infrastructural and financial barriers. The study recommends provision of adequate waste bins, regular waste collection, promotion of waste segregation, continuous health education, and stricter enforcement of sanitation regulations to improve environmental sanitation in market settings
