RESUMEN
Introduction: Mother-to-child transmission remains an important mode of transmission of hepatitis B infection particularly in endemic areas. The knowledge and practices of pregnant women about mother-to-child transmission (MTCT) of hepatitis B virus (HBV) may influence the uptake of strategies to reduce mother-to-child transmission of infection. Objectives: This study assessed the knowledge and willingness to uptake hepatitis B virus infection preventive services among pregnant women in Ado-Ekiti, Nigeria. Methods: This was a cross-sectional study that involved 373 pregnant women at the Ekiti State University Teaching Hospital (EKSUTH) and Maternal Child Specialist Clinics, Ado-Ekiti, Nigeria. A structured questionnaire was used to assess their knowledge, practices, and perceptions about MTCT of hepatitis B infection. Results: Only 52.5% (196) of the respondents had good knowledge, although the majority 290 (77.7%) had heard of hepatitis B infection prior to the survey. Only 147 (39.4%) of the respondents had ever had hepatitis B screening. More persons with professional jobs had good knowledge about hepatitis B infection compared with other occupations (p < 0.001). However, more respondents aged 30-34 years had poor knowledge about hepatitis B infection compared with other age groups (p = 0.045). Respondents with good knowledge about hepatitis B infection were willing to uptake hepatitis B infection prevention services (p < 0.001). Conclusion: This study showed that respondents with professional jobs had good knowledge about hepatitis B infection and those who had good knowledge about the infection were willing to utilize hepatitis B preventive measures. Awareness of MTCT of HBV did not translate into good practice as only few respondents had screened for hepatitis B. There is a need to intensify education about modes of transmission of hepatitis B infection with an emphasis on promoting good preventive practices.
RESUMEN
BACKGROUND: Limited human resource for health may impede the attainment of health-related sustainable development goals in low-income countries. This study aims to identify migration factors among final-year students of health-related disciplines at a Nigerian university, reflecting trends in Nigeria and sub-Saharan African countries. METHODS: A cross-sectional study was conducted using a semi-structured, self-administered questionnaire to collect data from 402 final-year students of Medicine/Dentistry, Nursing, Pharmacy and Occupational therapy Physiotherapy at Obafemi Awolowo University, Ile Ife. Univariate, bivariate and multivariate data analysis were conducted and a p-value < 0.05 was taken as statistically significant. RESULTS: The mean age of the respondents was 24.3 ± 2.3 years. Most (326; 81.1%) respondents had intentions to migrate and majority (216; 53.7%) of respondents had an unfavourable attitude towards practising in Nigeria. Students of Nursing constitute the highest proportion (68; 91.9%) of those willing to migrate (p = 0.009). The common preferred destinations for those who intend to migrate were the United Kingdom (84; 25.8%), Canada (81; 24.8%), and the United States of America (68; 20.9%). Respondents who had favourable attitude towards practicing abroad (AO.R: 2.9; 95% C.I 1.6-5.2; p = 0.001) were three times more likely to have migration intentions compared with those who had an unfavourable attitude towards practicing abroad, while the odds for those who had favourable attitude towards practicing in Nigeria (AO.R: 0.4; 95% C.I 0.2-0.7; p = 0.002) was two times less than those who had an unfavourable attitude towards practice in Nigeria. Respondents who desire specialist training (AO.R: 3.0; 95% C.I 1.7-5.4; p < 0.001) were three times more likely to have intention to migrate abroad when compared to those who were undecided or had no desire to pursue specialist training. CONCLUSION: Most respondents had the intention to migrate abroad after graduation and this could be attributed to the desire for specialist training and their attitude towards practising in Nigeria. Interventions aimed at improving specialist training in Nigeria and incentivizing health care practice may reduce migration trends among Nigeria's health professionals in training.

Background: Anaemia in pregnancy remains a severe public health problem in sub-Saharan African countries including Nigeria. Objectives: To assess factors associated with anaemia in pregnancy among Nigerian women. Methods: A secondary analysis of the 2018 Nigeria demographic health survey was conducted to determine the predictors of anaemia among Nigerian pregnant women (N=1522). SAS 9.4 was used for the analysis. Results: The prevalence of anaemia in pregnancy was 61.1%. On multivariable logistic regression analysis, women in the North-central (AOR=2.52, CI=1.46-4.35) and South-south (AOR=2.21, CI=1.06-4.59) had increased odds of anaemia in pregnancy, compared to those in the Northwest. Women with no education (AOR=2.38, CI=1.28-4.44), primary education (AOR=3.06, CI=1.58-5.96) and secondary education (AOR=1.75, CI=1.04-2.94) had increased odds of anaemia in pregnancy compared to women with teriary education. Also, women not in marital union had increased odds of anaemia in pregnancy compared to women in a union (AOR=2.56, CI=1.15-5.72). Women in the second (AOR=2.42, CI=1.79-3.29) and third trimesters of pregnancy (AOR=2.83, CI=2.07-3.89) had increased odds of anaemia. Conclusion: These findings are important for the control of anemia among pregnant Nigerian women. Women in the Northcentral and Southsouth zones are particularly at risk for anaemia in pregnancy and should receive special attention during antenatal care.

BACKGROUND: We evaluated cervical cancer program for women living with HIV (WLHIV) to determine program screening rate, primary case finder screening accuracy and treatment and post-treatment screening rate among screen-positive patients. METHODS: A ten-month review of cervical cancer program data among WLHIV aged 15-49 years on HIV care across forty-one comprehensive ART sites, supported by APIN (a PEPFAR implementing partner) for cervical cancer screening and treatment in Nigeria, was conducted from October 2020 to July 2021. Initial screening was done using visual inspection with acetic acid (VIA) followed by a gynaecologist expert review through a program-designed software named AVIVA, as a confirmatory test. Associations were measured between the primary case finder screening accuracy and study covariates at p-value of 0.05. RESULTS: About 10,289 asymptomatic women aged 15-49 years living with HIV were screened for cervical cancer by primary case finders using VIA-based screening test. About 732 (7.1%) had a positive screening test suggestive of precancerous lesions or cervical cancer. Three hundred and fifteen (43.0%) of VIA positive women had treatment using thermal ablation and less than one-third (21.6%) of those treated came back for post-treatment screening test. Primary case finder screening sensitivity, specificity, positive predictive and negative predictive accuracy using gynaecologist review as confirmatory test were 60.8%, 71.5%, 41.7% and 84.5% respectively. Overall screening accuracy was 68.8%. CONCLUSION AND RECOMMENDATIONS: This innovative approach to cervical cancer screening among WLHIV yielded modest results in preventing program error and wastages. Wider deployment of expert-based reviews of VIA though AVIVA software might be a veritable approach to improve screening accuracy in low resource settings.

The war in Syria, which started over 11 years ago, has devastated the country's water sources, healthcare system, and other vital facilities for healthy living. The country is vulnerable to outbreaks, especially epidemic-prone ones like cholera, due to its fragile health system. Syria experienced its last hit of cholera in 2009, which led to the deaths of several Syrian children and affected about 1,000 people. The current cholera resurgence in Syria calls for public concern. Considering the poor access to clean water, the forced relocation of people, and other destruction caused by the war, these factors have exposed Syrian children to infectious diseases like cholera. We argued for more efforts toward the implementation of Water, Sanitation and Hygiene (WASH) in the country. We also pointed out the need for proper education and sensitization campaigns using all available resources to educate the populace, mass chlorination of wells, mapping vulnerable areas, and implementing WASH while encouraging vaccination coverage for cholera as a strategy to reduce its incidence. Improving the national surveillance systems will aid in the timely and appropriate reporting of any outbreak. Again, more negotiations should be done to seek a lasting solution to ending the war and restoring peace and serenity in the country.

BACKGROUND: COVID-19 ranks as one of the largest public health threats in recent times. It is associated with huge health, economic and social consequences. Although vaccination is an effective control measure, COVID-19 vaccine uptake has been suboptimal in many low/middle income countries. Hence this study assessed the factors influencing COVID-19 vaccine uptake among Nigerian households. DATA AND METHODS: This study analyzed secondary data from the COVID-19 High-Frequency Phone Survey of Households that was collected by the National Bureau of Statistics between November 2021 and January 2022. Relevant data were analyzed using descriptive statistical tools and the Multivariate Regression model. RESULTS: Out of 2370 respondents, only 32.8% of the respondents were vaccinated against COVID-19. Respondents living in urban areas (34.4%) had a higher level of COVID-19 vaccine uptake relative to those living in rural Nigeria (30.9%). Results from the Multivariate Regression model revealed that adults aged ≥ 60 years (OR 2.20; p = 0.012), respondents with primary (OR 1.72; p = 0.032), secondary (OR 1.77; p = 0.025) and tertiary education (OR 3.03; p < 0.001), respondents with access to health insurance (OR 1.68; p = 0.004), those who obtained vaccine information from health workers (OR 3.92; p < 0.001), the government (OR 3.22; p < 0.001), and the mass media (OR 1.75; p = 0.003) were more likely to be vaccinated. Also, respondents living in North Central (OR 2.02; p < 0.001), North East (OR 1.48; p = 0.039), South West (OR 2.63; p < 0.001), and South South (OR 1.49; p = 0.031) regions had higher odds of being vaccinated. CONCLUSIONS: The study recommends increased media campaigns and advocacy for COVID-19 vaccination in the South East and North West regions. Persons with no formal education and younger persons aged 18-29 years should be targeted with COVID-19 vaccine-related information given that they were less likely to be vaccinated. Dissemination of relevant information through government sources, mass media and health workers is encouraged so as to positively influence decisions to receive COVID-19 vaccines among citizens.
RESUMEN
BACKGROUND: Global response to the growing burden of non-communicable diseases (NCDs) in developing countries includes the development of WHO Package of Essential Non-communicable Disease Interventions (WHO PEN) for Primary Health Care (PHC). The study assessed the level of preparedness of PHC facilities on implementation of essential NCD interventions in rural and urban Local Government Areas (LGAs) of Osun State, Nigeria. METHODS: The study was a comparative cross-sectional survey. Information was collected from heads of 33 rural and 33 urban PHC facilities and through direct observation on the domains of staff training, basic equipment, diagnostics and essential medicines for cardiovascular diseases, diabetes and chronic respiratory diseases (CRDs) using a semi-structured interviewer administered questionnaire. RESULTS: Manual sphygmomanometer was found in similar proportions (84.8%) of PHC facilities in rural and urban LGAs. Glucometer was available in 45.5% of the PHC facilities in urban and 33.3% of the PHC facilities in the rural LGAs, the difference was not statistically significant (χ2 = 1.015; p = 0.314). Basic equipment for CRDs were not available in majority of PHC facilities in both locations. Moduretic tablets were the most reported essential NCD medicines, available in 15% of PHC facilities in rural LGAs and none in urban LGAs. The anti-diabetic medicines were not available in any of the PHC facilities in both locations. More than 90% (≥ 30) of the PHC facilities in both locations were not prepared to implement essential interventions for each NCD across domains of staff training and essential medicines. Overall, 97.0% of the PHC facilities in the rural LGAs and all the PHC facilities in urban LGAs were not prepared on implementation of essential interventions for the three NCDs. CONCLUSION: The level of preparedness of the PHC facilities on implementation of essential NCD interventions in the rural and urban LGAs of Osun State is very low. Government needs to strengthen the PHC system by providing needed essential medicines, basic diagnostics, equipment, and training of clinical health care workers for implementation of essential NCD interventions in the state.

PURPOSE: Knowledge of adolescents' intention to sustain female genital mutilation (FGM) practice is required to guide efforts to eradicate FGM in Africa and Asia where about 200 million women are affected. Nigeria has one of the highest FGM cases in the world. The study sought to determine the knowledge, attitude, and intentions of adolescents to sustain FGM practice when they become parents. MATERIALS AND METHODS: This study is a cross-sectional descriptive survey of 195 in-school adolescents aged 14-19 years, in Imesi-Ile, a rural town in South-west Nigeria selected through a multistage sampling method. RESULTS: Overall, 44.6% of adolescents had good knowledge of FGM, while 44.6% had a positive attitude and 55.4% had a negative attitude towards FGM. More females (57.4%) have a negative attitude towards FGM. About 42.1% of adolescents intend to continue the practice of FGM, while 47% have no intentions and 10.8% remain undecided. Gender, age group and family affluence were not statistically associated with intention to continue FGM. CONCLUSION: Intention to continue FGM practice is high among adolescents in the rural community. FGM eradication campaign among adolescents should seek to improve knowledge, attitude and intentions towards FGM practice.

Introduction: The challenges posed by the COVID-19 pandemic have necessitated the increasing use of online virtual training platforms. The objectives of the study were to assess the acceptability, appropriateness and feasibility of virtual space in strengthening the research capacity in Nigeria. Materials and Methods: Data were collected through an adapted online questionnaire from participants following a 2-day webinar. Both descriptive and inferential (bivariate and multivariate) analyses were done. Results: The findings of the study revealed that 55.2% of participants (n = 424) were males and 66.0% (n = 424) were early career researchers. Two hundred and thirty-six participants (55.7%) (n = 424) reported very good acceptability, 67.9% (n = 424) reported very good appropriateness while 54.7% (n = 424) reported good feasibility of webinar for research capacity strengthening. The rating of knowledge obtained from the webinar as 'excellent' increased the odds of acceptability (odd ratio [OR] = 38.30; P < 0.001), appropriateness (OR = 15.65; P < 0.05), and feasibility (OR = 20.85; P < 0.05). Furthermore, the preference for zoom and other online platforms for learning increased odds of acceptability of the webinar (OR = 2.29; confidence interval [CI]: 0.97-57.39; P < 0.05), appropriateness (OR = 2.55; CI: 1.10-5.91; P < 0.05) and feasibility (OR = 2.34; CI: 0.96-5.74; P < 0.05). Conclusion: The study concluded that webinar was acceptable, appropriate and feasible for strengthening research capacity, although poor internet connectivity and cost of data were the major challenges in Nigeria. However, a learner-centred approach in contents' delivery that ensures optimal learning has the potential of enhancing research capacity strengthening via virtual space.

Insecticide treated nets (ITN) are effective in malaria prevention; however, they remain underutilized among children. A secondary analysis of the 2018 Nigeria-Demographic and Health Survey including logistic regression was conducted to determine factors influencing ITN use among under-fives (U5s). Overall, 22,954 (72.4%) slept under ITN the night before the survey. Children <4 years and those in the northern regions had significantly higher odds of using ITN, as did those from households with ≤6 members and those from the lowest to middle wealth quintiles. However, among those households recorded as having "universal ITN coverage" i.e. at least one net between two persons, children <3 years, those from the rural northern regions and those from the lowest wealth category had significantly higher odds of using ITN. Interventions to improve ITN use by U5s should be intensified among households with larger size, those from the highest wealth quintiles and residents in southern Nigeria.

OBJECTIVES: We assessed Case Fatality Rate (CFR) of COVID-19 as an indicator to situate the performance of Nigeria relative to other selected countries. We obtained case fatality rates of different countries from data sets available from open-sources. The CFRs were calculated as the rate of deaths compared with total cases. The values were compared with Nigeria's COVID-19 CFR. Other relevant statistical comparisons were also conducted. RESULTS: The worst performing countries with regards to CFR in descending order were Yemen (19.5%), Peru (9.0%) Mexico (7.6%), Sudan (7.4%) and Ecuador (6.3%) while the best performing nations were Bhutan (0.11%), Burundi (0.19%), Iceland (0.20%), Laos (0.21%) and Qatar (0.25%). The CFR of Nigeria was 1.39% which falls below the 50th percentile. Other comparison done showed significant difference in the CFR values between countries similar to Nigeria and countries that are dissimilar when HDI is used. (Mann-Whitney U test 126.0, p = 0.01). The trend of the CFR in Nigeria showed a steady decline and flattening of the CFR curve which does not seem to be affected by the spikes in the daily declared cases.

Introduction: consistent condom use remains an integral and essential part of comprehensive Human Immunodeficiency Virus (HIV) prevention and care programme. This study assessed consistent use of condom among HIV-positive women of reproductive age on antiretroviral treatment and its associated factors. Methods: a cross-sectional survey of 360 women living with HIV (WLHIV) receiving treatment in four APIN Public Health Initiatives, Nigeria supported President's Emergency Plan for AIDS Relief (PEPFAR) comprehensive Antiretroviral Therapy (ART) sites in Ogun State was conducted from October 2018 to March 2019. Information were collected on consistent condom use among respondents and their associated factors using a pre-tested questionnaire. Data were analysed using SPSS IBM version, with statistical significance set at 0.05. Results: the mean age of the women was 38.1 ± 5.8 years. About two-fifth (39.4%) of the respondents reported consistent use of condom. Of the 142 respondents who reported inconsistent use of condom, 51.6% and 37.5% mentioned sexual displeasure and partner's disagreement respectively as reasons for inconsistent use. Factors associated with consistent condom use were marital status (p < 0.001), respondent's occupation (p = 0.040), partner's occupation (p = 0.012) and partner's HIV status (p = 0.045). Respondents with HIV negative partners were 1.8 times more likely to use condom consistently compared to those with HIV positive partners (AOR = 1.826, CI = 1.018 - 3.274). Conclusion: this study concludes that there is poor consistent condom use among WLHIV in Ogun State. The rate is worse among the sero-concordant partners than the sero-discordant partners. More needs to be done through behaviour change communication aimed at improving consistent condom use among HIV clients.

BACKGROUND: In Nigeria, about 1.25million induced abortions occur annually and the country accounts for one-fifth of abortion-related deaths globally. OBJECTIVES: The study aimed to assess the determinants of induced abortion among married women. METHODS: A mixed methods study was conducted in Ile-Ife, Nigeria. The quantitative component employed a cross-sectional study design while the qualitative aspect comprised focus group discussions. Information on contraceptives use, unintended pregnancy and induced abortion were obtained from 402 married women (with at least one child) aged 18-49 years using a semi-structured questionnaire. Four focus group discussion sessions were conducted among women of reproductive age. RESULTS: Majority (67.2%) of respondents had ever used a contraceptive method. However, 34.3% of the women have had unintended pregnancies and 14.2% had induced abortion. FGD findings revealed that non-use of contraceptives and contraceptive failure were major reasons for unintended pregnancies and induced abortion. The significant predictors of induced abortion were non-use of contraceptives, age≥ 40 years and multiparity. CONCLUSION: Induced abortion still occur among married women particularly those not using contraceptives, aged ≥40 years and those with high parity. More emphasis should be placed on making contraceptives more accessible to married women.

BACKGROUND: Automobile spray painters in Nigeria are exposed to organic solvents due to the hazardous nature of their work. Inadequate use of personal protective equipment (PPE) may intensify exposure to high levels of chemical hazards with resultant health problems. OBJECTIVES: The present study assessed PPE use and work practices and compared work-related health problems of spray painters and controls in Ile-Ife, Nigeria. METHODS: A cross-sectional study was conducted among 120 spray painters and 120 controls (electronic technicians). Data on socio-demographics, work practices, knowledge about organic solvent-related hazards and self-reported health symptoms were obtained using a semi-structured questionnaire. Clinical examinations were performed for all respondents and the composition of organic solvents in paints and paint products were derived from material safety data sheets. RESULTS: All respondents were male, and the mean age was 32.7±13.8 years for painters and 33.9±15.5 years for controls. Few (7.5%) painters perceived their use of PPE to be adequate. All spray painters worked in enclosed workshops and N-butyl acetate was the most commonly used organic solvent. Spray painters reported excessive tear production, recurrent cough, and short-term memory loss more frequently than controls (P<0.05). In addition, 89% of painters noticed paint-stained sputum immediately after spray painting. The prevalence ratio of respiratory symptoms was higher in spray painters than controls (prevalence ratio=21.0, CI=2.9-153.6). On clinical examination, more spray painters had corneal opacity and dry skin when compared with controls (P<0.05). CONCLUSIONS: Spray painters in the study area worked amidst chemical hazards and had poor use of PPE. Exposure to organic solvents may be responsible for the higher prevalence of self-reported health problems among spray painters. Interventions to enforce the use of PPE and improve the knowledge of organic solvent-related hazards among spray painters are essential. PARTICIPANT CONSENT: Obtained. ETHICS APPROVAL: Ethical approval to conduct the study was obtained from the Health Research and Ethics Committee of the Institute of Public Health, Obafemi Awolowo University, Ile-Ife Nigeria (HREC No: IPHOAU/12/463). COMPETING INTERESTS: The authors declare no competing financial interests.
RESUMEN
INTRODUCTION: Occupational safety measures when put in place in organizations are expected to increase the productivity of employees and drive organizations to better performance. This study was aimed at assessing the perception of workers at the Warri Refining and Petrochemical Company (WRPC) on the effect of implemented occupational safety measures on their individual and organizational performance. MATERIALS AND METHODS: The study was cross-sectional in design conducted at the WRPC, Delta state, Nigeria, among 236 workers of the WRPC selected via a simple random sampling technique across different job cadres (junior, senior, and management) in the organization. Data were collected using a semi-structured self-administered questionnaire and analyzed using the descriptive and inferential statistical tests of the SPSS version 20 with statistical significance set at P < 0.05. RESULTS: The mean age of respondents was 43 ± 2.26 years with a male-to-female ratio of 1.8:1. More than 50% of the respondents attested that occupational safety measures had been well implemented at the WPRC. Almost all the respondents, 219 (92.8%) and 224 (94.9%), agreed that occupational safety measures in place and trainings on safety measures had improved individual worker's performance, respectively. Respondents' length of service and job cadres were significantly associated with their perceived effect of the existing occupational safety measures at the WRPC on individual worker and organizational performance (P < 0.001). They were also significantly associated with their perceived effect of the neglect of these safety measures on high labor turnover rate (P < 0.001). CONCLUSION: Occupational safety measures were perceived to have positively affected workers' and organizational performance.
RESUMEN
BACKGROUND: Furniture making industries are small scale businesses that commonly use organic solvents. There has been minimal focus on the health effects of this chemical hazard on the nervous system among furniture makers in Nigeria. OBJECTIVES: The present study aimed to assess the association between organic solvents exposure and neurobehavioral status of furniture makers, using electronic technicians as a comparison group. METHODS: A comparative cross-sectional study design was employed. A sample size of 108 was calculated for each group. A semi-structured interviewer-administered questionnaire was used to obtain data on the socio-demographic variables and use of personal protective equipment (PPE). A proforma was developed to collect neurobehavioral assessment data. A checklist was used to assess the furniture makers' workshops. Air was sampled from all of the workshops in both the study and comparison groups to determine the concentration of total volatile organic compounds (TVOCs). RESULTS: The use of PPE was poor in both the study and comparison groups, with no significant difference between them (34.4% and 37.7% respectively). Total volatile organic compound and formaldehyde (HCHO) concentrations were significantly higher at the furniture makers' workshops compared with electronic technicians (p<0.001) for both chemicals. The 8-hour time-weighted average of TVOC was also higher in the furniture makers' workshops (4.4±0.6 mg/m3) compared with the control group (0.3±0.3 mg/m3). The neurobehavioral symptoms score was significantly higher among the study group relative to the comparison group (p<0.001). There was a significant difference in the outcome of the auditory verbal learning test, total recall (p=0.005), and delayed recall (p=0.003). There was no significant association between solvent exposure index and findings from the simple reaction time test. CONCLUSIONS: Poor compliance with the use of PPE among furniture makers may increase their exposure to organic solvents. There were more neurobehavioral changes in the furniture makers with a higher exposure index. Measures are needed to educate artisans about workrelated chemical hazards and ensure compliance with basic occupational safety and hygiene standards. PARTICIPANT CONSENT: Obtained.

RESUMEN
BACKGROUND: Extremity arterial injuries are an important cause of loss of life/limb after trauma. Early intervention is important for the good outcome. OBJECTIVES: The objective of this study is to review the pattern of presentation and study the factors that influences the outcome of extremity arterial injuries in our hospital. PATIENTS AND METHODS: This is a retrospective study of all patients with injuries to the extremity arteries requiring surgical intervention from July 2007 to June 2015. Data obtained included biodata, ischemic time, arteries involved, surgical intervention, and outcomes and analyzed using SPSS version 22. SETTING: Our hospital is the main referral hospital for vascular trauma serving four adjoining states in Nigeria and is linked to major cities by at least 3 Trunk-A federal roads. SUBJECTS: The subjects are patients who were managed in our cardiovascular surgical unit for the study duration (July 2007-June 2015) who had extremity arterial injuries. RESULTS: A total of 36 patients presenting with 40 arterial injuries in 37 limbs were studied. The mean age was 28.4 ± 10.3 years with male preponderance (88.9%). Gunshot injuries were the most common cause of arterial injuries (37.8%), followed by assault (27%). The mean time from injury to presentation for acute injuries was 20.4 h but 23 of the patients (63.8%) presented to the accident and emergency department within 12 h of injury. A limb salvage rate of 64.9% was achieved though ischemic times of ≥12 h were associated with poor outcomes. CONCLUSION: Prolonged ischemic time is associated with poor outcomes. Efforts should be put in place to reduce the limb ischemic times.
RESUMEN
BACKGROUND: Nigeria has a growing spray painting industry, however, the burden of occupational health problems related to organic solvent exposure among spray painters in Nigeria is under-studied. OBJECTIVES: This study aimed to assess workshop characteristics and ambient concentration of total volatile organic compounds (VOCs) in spray painting workshops and to compare lung function status and total serum bile acid levels of spray painters and controls. METHODS: A cross-sectional study design was employed to survey 120 spray painters and 120 controls (electronic technicians). A semi-structured questionnaire was used to obtain data on socio-demographics characteristics of the respondents. Weight, height and lung function of respondents were measured. In addition, a checklist was used to survey the spray painting workshops. Total VOC levels were determined in 37 spray painting and 31 electronic workshops. Data were analyzed using Statistical Program for the Social Sciences (SPSS) version 20 and a p-value of <0.05 was considered to be statistically significant. RESULTS: Windows were present in only 5 (13.5%) spray painting workshops and 23 (62%) workshops had a retractable tarpaulin at the entrance. Only 9 (24%) workshops had changing rooms, while fire extinguishers and first aid kits were not present in any of the surveyed workshops. A respirator with filter was sighted in only 1 (3%) workshop. The 8-hour time weighted average concentration of total VOCs in spray painting workshops was 13.4 ppm, which is above the national permissible exposure limits of 1.9 ppm. Forced vital capacity (FVC) percent predicted was significantly lower in spray painters (93.9 ±10.8%) than controls (96.7± 8.2%) (t = -2.326, df=238 p< 0.001). In addition, forced expiratory volume in the first second (FEV1) percent predicted was lower in spray painters (94.6±12.2%) than controls (100.3±9.1%) (t=-4.058, df=238, p=0.002). FEV1/FVC% was significantly lower among spray painters (85.48±8.70%) compared with controls (87.88±6.22%) (t=-2.861 df=238, p= 0.005). Total serum bile acids was significantly elevated in painters (8.71±3.39 mmol/l) compared to controls (4.67 ±2.15 mmol/l) (t=10.358, df=213, p<0.05). CONCLUSIONS: Spray painters in the present study conduct their activities in hazardous work settings. More needs to be done concerning workplace regulation and enforcements to ensure that spray painters comply with minimum standards of occupational safety, workplace hygiene and sanitation. PATIENT CONSENT: Obtained. ETHICS APPROVAL: Ethical approval was granted by the Health Research and Ethics Committee of the Institute of Public Health, Obafemi Awolowo University.
RESUMEN
An audit of 954 family planning clinic attendees, who received counselling from 2006 to 2010, was conducted at the only federal government owned tertiary hospital in Ondo state, Nigeria. Of these, 637 (66.8%) accepted a family planning method: 47.6% chose injectables, 23.2% intrauterine device, 19.5% oral contraceptive pills, 4.4% barrier methods, 3.3% implants and 2% tubal ligation. Clients who had some primary education [OR: 2.79; (95% CI: 1.14-6.84; p < 0.05] had statistically significant higher odds of accepting any contraceptive method while those with elevated blood pressure at first visit [OR: 0.23; 95% CI: 0.12-0.45; p < 0.001] and those with previous episode(s) of induced abortion OR: 0.57; 95% CI: 0.43-0.76; p < 0.001] had statistically significant lower odds of using any method. Concerted efforts at increasing uptake is advocated to bridge the gap between client counselling and uptake.
