Methods: Public school teachers (n = 111) were recruited between 14 December 2021, and 31 January 2022, for an anonymous online survey with questions on seven important topics related to: (1) population demographics, (2) teachers’ perceptions of COVID-19 in the workplace, (3) masks, (4) physical distancing, (5) surface transmission routes, (6) air flow, and (7) contact tracing protocols. Descriptive statistics were calculated, and statistically significant differences in categorical responses by grade level taught were investigated with Fisher’s exact test. Results: There were 76 complete responses. No significant differences across grade levels were found. More than half (53%, 43/81) reported not feeling protected from occupational COVID-19 exposure. Lack of mask ...

This study predicted exposure to dust particles using spirometric index and perception studies among farmers in selected farm settlements in Ogun State. Using a cross-sectional comparative study design involving, 195 consenting farmers and non-farmers for interview and on-the-spot lung functions test; and ambient levels of suspended particulate matter were determined. Data collected were evaluated through descriptive and inferential statistics. Results showed that most of the farmers (51.8%) applied manures, fertilizers and chemical sprays without the use of PPEs. A large portion of farmers (74.9%) and non-farmers (82.1%) understood that poor quality of air could result in respiratory diseases. TSP (29.89 ± 23.52 µg m-3) and PM10 (18.45 ± 16.97 µg m-3) were observed at the highest concentration during the wet sea...

The objective of this study is to investigate the concentration of urinary 1-OHP among charcoal workers as subjects and non-charcoal workers as controls. Methods: Early morning urine samples were collected from 68 persons (25 charcoal workers in Igbo-Ora, 20 charcoal workers in Alabata, and 23 non-charcoal workers) who volunteered to participate in this study. 1-OHP determination in urine samples was carried out using high performance liquid chromatography after hydrolysis. Descriptive and inferential statistics were used for data analysis at p < 0.05. Results: The mean urinary 1-OHP concentration (mmol/mol creatinine) among charcoal workers at Igbo-Ora and Alabata and non-charcoal workers were 2.22 AE 1.27, 1.32 AE 0.65, and 0.32 AE 0.26 (p < 0.01). There existed a relationship between respondent type and 1-OHP concentration. Charcoal workers were 3.14 times more at risk of having 1-OHP concentrations that exceed the American Conference of Governmental Industrial Hygienists guideline of 0.49 mmol/mol creatinine than non-charcoal workers (relative risk ¼ 3.14, 95% confidence interval: 1.7e5.8, p < 0.01). Conclusion: Charcoal workers are exposed to PAHs during charcoal production and are at risk of experiencing deleterious effects of PAH exposure. Routine air quality assessment should be carried out in communities where charcoal production takes place. Assessment of urinary 1-OHP concentration and use of personal protective equipment should also be encouraged among charcoal workers.

Vehicular emissions are the primary daily ambient source of CO in urban Nigerian motor parks, where there have been few human exposure studies. Using a cross-sectional comparative design, we assessed carboxyhaemoglobin levels (% COHb), a biomarker of CO exposure, among traders at three motor parks (AMP, IMP, and NMP) and other traders (nonmotor park workers) in Ibadan, Nigeria, using a noninvasive pulse CO-dosimeter (Rad 57). Ninety-three traders were proportionally allocated between motor parks; 93 other traders were selected based on specific study inclusion criteria. Mean ages of motor park traders and other traders were comparable, 37.8 ± 11.1 and 38.7 ± 9.6, respectively. Mean % COHb for traders (range 3-22) at AMP, IMP, and NMP was 11.2 ± 3.8, 11.6 ± 3.1, and 12.2 ± 3.3, respectively, while mean % COHb for other traders was about three times lower, 4.1 ± 1.7 (range 2-8). Overall, mean % COHb for m...

The public service workers, who are facilitators of national development, are particularly vulnerable because the nature of their job predisposes them to unhealthy lifestyles. However, there is paucity of reference data on the profile of cardiovascular risks among public servants in Nigeria. Therefore, this study determined the pattern and predictors of cardiovascular risk among public servants in Southwest, Nigeria. METHODS A total of 1,778 public servants were recruited from 47 Ministries, Departments and Agencies in Ondo State through multi-stage random sampling technique. The World Health Organization Stepwise instrument and Framingham Heart Study non-laboratory cardiovascular risk assessment tool were used to collect data. STATA version 14.2 was used for analysis and p-value of< 0.05 was taken as significant. RESULTS The mean age of participants was 44.2±9.1 years. They were predominantly females (6...

The public service workers, who are facilitators of national development, are particularly vulnerable because the nature of their job predisposes them to unhealthy lifestyles. However, there is paucity of reference data on the profile of cardiovascular risks among public servants in Nigeria. Therefore, this study determined the pattern and predictors of cardiovascular risk among public servants in Southwest, Nigeria.
METHODS: A total of 1,778 public servants were recruited from 47 Ministries, Departments and Agencies in Ondo State through multi-stage random sampling technique. The World Health Organization Stepwise instrument and Framingham Heart Study non-laboratory cardiovascular risk assessment tool were used to collect data. STATA version 14.2 was used for analysis and p-value of< 0.05 was taken as significant.
RESULTS: The mean age of participants was 44.2±9.1 years. They were predominantly females (64.8%). The proportions of participants with moderate and high 10-year absolute cardiovascular risks were 18.3% and 5.6%, respectively. Significant factors associated with increased cardiovascular risk were age (p=<0.001), sex (p =<0.001), education (p =<0.001), income (p =<0.001), staff category (p =<0.001) and employment
grade level (p=<0.001). The significant predictors of increased cardiovascular risk on multivariate analysis were age > 50years (AOR:1.25;CI:1.19-1.32;p=<0.001) and male sex (AOR:6.62; CI:3.76-11.65;p=<0.001).
CONCLUSION: The prevalence of increased 10-year absolute cardiovascular risk among public servants in Ondo State was high. The significant predictors were age >50 years and male sex. Cardiovascular risk reduction strategies should be encouraged among public servants especially the older males.

Thus, this comparative cross-sectional work employed a spirometric index and perception studies by conducting interviews and on-thespot lung function tests on 195 farmers living in seven farm settlements of Ogun State and 195 non-farmers living in other areas to assess the ambient levels of the suspended particulate matter and estimate the dust exposure among the first group. The collected data were evaluated through descriptive and inferential statistics and indicated that the majority of the farmers (51.8%) applied manure, fertilizer and chemical sprays without using personal protective equipment (PPE), although a large percentage of both the farmers (74.9%) and the non-farmers (82.1%) understood that poor air quality could cause respiratory disease. The highest concentrations of the total suspended particles (TSP; 29.89 ± 23.52 µg m-3) and PM10 (18.45 ± 16.97 µg m-3) were observed during the wet season, whereas that of the PM2.5 (18.45 ± 11.72 µg m-3) was observed during the dry season. Additionally, the mean concentrations of the PM10 and PM2.5 exhibited significant seasonal variation (p < 0.001). The forced expiratory volume in 1 second (FEV1) and peak expiratory flow rate (PEFR) also varied considerably between the farmers (1.16 ± 0.87 and 244.32 ± 117.96, respectively) and non-farmers (2.47 ± 0.87 and 271.29 ± 104.09, respectively). Our results showed that the farmers engaged in poor safety practices and possessed reduced lung function compared to non-farmers. Hence, we advise farmers to adopt the use of PPE and follow safety measures. Furthermore, routine assessment of particulate matter and lung function should be encouraged in farm settlements.

Objectives: We investigated the knowledge, attitude and self-reported hygiene practices towards hospital infection control among healthcare workers (HCWs) at the State Specialist Hospital, Akure, Nigeria. Methods: This descriptive cross-sectional study involving self-administered, structured questionnaires administered to 137 randomly selected HCWs (19 doctors, 66 nurses and 52 health assistants) was conducted in 2015. Descriptive and inferential statistics were used for data analysis at 5% level of significance. Results: Mean age of HCWs was 39.81 ± 8.69 years. Majority (84.7%) was trained on hand hygiene and was knowledgeable about HAIs (86.9%), modes of transmission (57.7%) and effectiveness of hand hygiene (94.9%). However, about half (48.9%) of the HCWs reported did not adhere to hand hygiene often, b...

This paper analyses primary health care (PHC) in Nigeria and showcases performance-based financing as a tool for health system reform. This study adopted content analysis methodology involving review of peer-reviewed and grey literature to analyse Nigeria’s PHC system thematically using the World Health Organization’s health system building blocks framework. The study shows that PHC in Nigeria is underperforming in all the six building blocks while performance-based financing is an approach to health system reform with capacity to strengthen each building block of the health system. With strong institutional arrangement, performance-based financing may be adopted as a national policy to reform PHC system in Nigeria for improvement in access, utilization and quality of healthcare in Nigeria.

Vehicular emissions are the primary daily ambient source of CO in urban Nigerian motor parks, where there have been few human exposure studies. Using a cross-sectional comparative design, we assessed carboxyhaemoglobin levels (% COHb), a biomarker of CO exposure, among traders at three motor parks (AMP, IMP, and NMP) and other traders (nonmotor park workers) in Ibadan, Nigeria, using a noninvasive pulse CO-dosimeter (Rad 57). Ninety-three traders were proportionally allocated between motor parks; 93 other traders were selected based on specific study inclusion criteria. Mean ages of motor park traders and other traders were comparable, 37.8 ± 11.1 and 38.7 ± 9.6, respectively. Mean % COHb for traders (range 3–22) at AMP, IMP, and NMP was 11.2 ± 3.8, 11.6 ± 3.1, and 12.2 ± 3.3, respectively, while mean % COHb for other traders was about three times lower, 4.1 ± 1.7 (range 2–8). Overall, mean % COHb for motor park traders, 11.7 ± 3.3, was also significantly higher than for other traders (p < 0.05). Nevertheless, mean % COHb for both groups exceeded the current World Health Organization guideline, 2.5%. This study suggested that motor park traders have higher % COHb and thus are highly susceptible to exposure and more vulnerable to known risks of adverse health effects from exposure to CO.

This study investigated human factor issues that are responsible for maritime accidents in Nigeria and therefore gives maritime practitioners strategies for policy interventions. The study adopted a descriptive methodology, making use of survey design to collect data from 284 marine service operators in Nigeria. Data for the study was collected through semi-structured questionnaires, same were analysed through descriptive and inferential statistical tools such as mean, standard deviation, correlation and regression analysis at P < 0.05. Results showed that nine human related factors are major causes of marine accidents; namely: poor crew interaction, crew fatigue, drugs and alcohol use, unsafe vessel speed, commercial pressure from management, complicated work processes, gap in working knowledge, faulty crew judgment and unruly behaviour; while five of them: Crew fatigue, drugs and alcohol use, unsafe vessel speed, faulty crew judgment and unruly behaviour of crewmembers, were significantly related to safety performance. The study established that human errors are contributory factors to marine accidents and relationships exist between them and safety culture, hence, human factors can predict safety performance in maritime organizations in Nigeria. It is therefore recommended that Marine Safety Performance Plan, which is part of the International Safety Management (ISM) Code, be implemented in all maritime companies in Nigeria. Alcoholism, indiscriminate drug and substance use should be discouraged onboard while a stress management policy should be designed to handle work-related fatigue.
