Work environment and hypertension in industrial settings in Benin in 2019: a cross-sectional study.

OBJECTIVE: To determine the association between occupational factors, particularly psychosocial factors, and hypertension. DESIGN: Descriptive and analytical cross-sectional study using logistic multivariate regression. SETTING: Fifteen cotton ginning plants in Benin. PARTICIPANTS: Permanent and occasional workers in the cotton ginning industry. DATA COLLECTION: Data on sociodemographic, occupational, behavioural and clinical history characteristics were collected using a number of standardised, interviewer-administered questionnaires. These questionnaires were based on the WHO's non-communicable disease questionnaire, Karasek questionnaire and Siegrist questionnaire. Weight, height and blood pressure were measured. Any worker with systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg according to the WHO criteria was considered hypertensive, as was any subject on antihypertensive treatment even if blood pressure was normal. RESULTS: A total of 1883 workers were included, with a male to female ratio of 9.08. Of these, 510 suffered from hypertension (27.1%, 95% CI 25.1 to 29.2). In the multivariate analysis, the risk factors identified were occupational stress (adjusted OR (aOR)=3.96, 95% CI 1.28 to 12.2), age ≥25 years (aOR=2.77, 95% CI 1.55 to 4.96), body mass index of 25-30 kg/m2 (aOR=1.71, 95% CI 1.32 to 2.2), body mass index >30 kg/m2 (aOR=2.74, 95% CI 1.84 to 4.09), permanent worker status (aOR=1.66, 95% CI 1.44 to 2.41) and seniority in the textile sector >5 years (aOR=2.18, 95% CI 1.7 to 2.8). Recognition at work emerged as an effect-modifying factor subject to stratification. CONCLUSIONS: Occupational factors, particularly job strain and recognition at work, are modifiable factors associated with hypertension in the ginning plants sector and deserve to be corrected through occupational health promotion and prevention.

Main challenges of the detection in the context of global health security: systematic review of Joint External Evaluation (JEE) reports.

Introduction: since 2016, Joint External Evaluation (JEE) missions have been organized in various countries. This systematic review of the JEE reports is intended to identify the main challenges (MC) of detection in WHO regions. Methods: we accessed JEE reports on the WHO website. Challenge was defined as a variable of the indicators of detection where there was a need of improvement. MC was a challenge common to at least one-third of countries in each region and globally. For consistency, we assessed challenges reported under "Areas which need strengthening/challenges" in reports. Results: we analyzed 96 JEE reports. African Region (91.7%), Eastern Mediterranean Region (80.9%) and South East Asia Region (72.7%) had the highest rates of JEE completion. The MC were 24 in European Region, 26 in Mediterranean Region, 30 in Western Pacific Region, 33 in South East Asia Region and 34 in African Region. 24 MCs were identified at global level. National laboratory system and Real time surveillance had the highest number of MC. Eleven MCs were common to all WHO regions and global level. These include insufficient capacity for core test confirmation, insufficient specimen referral system, weak quality management system, issues in laboratories licensing and accreditation, weak data management, weak electronic reporting system, absence /weak mechanism of information exchange between International Health Regulation and animal health focal points, insufficient health professional specialists, the need of workforce strategy, the need of field epidemiology and insufficient workforce retention capacity. Conclusion: the MCs identified should be addressed through a global approach.

Occupational stress in industry setting in Benin 2019: A cross-sectional study.

BACKGROUND: Occupational stress is a psychosocial risk in the workplace. Working conditions in industrial settings may lead to occupational stress. In Benin, however, there is little epidemiological data on occupational stress in industrial settings. We aimed to determine the prevalence and factors associated with occupational stress in industrial settings in Benin in 2019. METHODS: This was a prospective, cross-sectional study conducted from January 31 to April 11, 2019, among 15 cotton ginning plants. Sampling was exhaustive for permanent workers and stratified in clusters by shift for occasional cotton gin workers. Data were collected through Karasek and Siegrist questionnaires. Data analysis was performed using R software. Binary multivariable logistic regression was performed. The significance level was p < 0.05. RESULTS: Of 1883 workers included, 90.8% were male. The median age was 38 years (IQR: 28 years to 49 years). The prevalence of occupational stress was 77.7% (95% CI: 75.8-79.6). Psychological demand was high in 93.0% of workers and 83.9% had low decision latitude. Among the workers, 16.3% had low social support and 89.9% had a low recognition score at work. Factors associated with occupational stress were: being an occasional vs. permanent worker (aOR 6.43, 95% CI 4.18 to 9.88); age less than 38 years (aOR 0.55, 95% CI 0.41 to 0.76); high intensity physical activity at work (aOR 1.33, 95% CI 1.03 to 1.73); working in production vs. administration (aOR 1.59, 95% CI 1.03 to 2.45); spending fewer than 4 years at the current work location (aOR 1.60, 95% CI 1.05 to 2.44); and scoring low for recognition at work (aOR 1.53, 95% CI 1.04 to 2.23). Noise exposure and being a shift worker were significant in univariable analysis, but not multivariable analysis. CONCLUSION: Occupational stress is very common among workers in industrial settings. The implementation and evaluation of preventive measures against these risk factors is necessary.

Assessment of the Biosafety and Biosecurity in the Reference Veterinary Laboratory of Parakou in Benin.

Optimal biosafety and biosecurity are major requirements of global health security. This study assessed the biorisk management in the reference veterinary laboratory of Parakou (Benin). The study was cross-sectional, descriptive, and evaluative. The non-probability sampling method with the reasoned choice was used. The Food and Agriculture Organization laboratory mapping tool-safety was used to collect information from the laboratory team. Group discussion, working environment observation, and document exploitation were the data collection techniques. The biorisk management was rated good if the average indicator of the laboratory reached at least 80%. Otherwise, the biorisk management was rated insufficient. The overall laboratory biosafety and biosecurity score was insufficient (42.4%). Per area, the scores were 26.7% for engineering, 33.3% for administration, 53.8% for personal protective equipment, and 62.3% for the operational. There was no area or category score that reached 80%. Containment, waste disposal, and personal protective equipment disposal were the best performing categories with a score above 60%. The laboratory has no biosafety and accident prevention program. Its premises require renovation. The standard operating procedures for biosafety are not yet finalized, and the training mechanism is not optimal. Therefore, strong advocacy and implementation of a biorisk management improvement plan appear as urgent corrective actions which are required to help the reference veterinary laboratory of Parakou in its task to protect the livestock and, ultimately, the people of Benin from dangerous diseases and emerging pathogens.

Health status of a sample of Beninese seafarers examined on the occasion of medical fitness for work at sea.

BACKGROUND: In view of the considerable risks involved in maritime work, the medical fitness of seafarers is of paramount importance. A study carried out in May 2018 in Benin made it possible to describe the health profile of seafarers who received a medical examination before boarding and to identify the diseases likely to hinder their medical aptitude for this profession. MATERIALS AND METHODS: This is a retrospective cross-sectional study that was based on 125 medical files registered from 2013 to 2017 and selected on the basis of the criteria of completeness, readability and non-overload of the entries. RESULTS: The results showed that more than half (63.2%) of the seafarers in our series are over 40 years old. The prevalence of high blood pressure was 28.4% in the seafarer population. Obesity was detected in 21.5% of subjects. Of the moderate cases of hearing loss found, 4 out of 5 worked at the machine station. The unrestricted fitness level was 86.4%. One (0.8%) case of physical restriction and 12.8% of cases of mandatory wearing of medical glasses at work were reported. The "healthy worker effect" may underestimate the risk of marine activity to the health of seafarers when referring to the general population. CONCLUSIONS: The study provides opportunities to improve the seafarers' health situation in accordance with international provisions such as the Maritime Labour Convention, 2006 (MLC, 2006) ratified by Benin in June 2011.

[Prevalence and factors associated with low back pain among motorcycle drivers in Porto-Novo (Benin)]. / Prévalence et facteurs associés à la lombalgie chez les conducteurs de taxi moto à Porto-Novo (Bénin).

INTRODUCTION: low back pain is a major health problem in the workplace. Some populations of workers appear to be much more exposed than others. The aim of this study is to determine the prevalence and the factors associated with the occurrence of low back pain among motorcycle drivers in Porto-Novo. METHODS: we conducted a cross-sectional descriptive and analytical study of 270 consenting motorcycle drivers with at least one year of seniority. Patients were asked to complete the Nordic Questionnaire adapted to our context and physical examination of the spine was performed. Data were analyzed using Epidata 3.1. Software and STATA/IC 11.0. The threshold significance level was 5% and the confidence intervals were 95%. RESULTS: the prevalence of low back pain was 68.89%. The average age of motorcycle drivers was 42.43 ±11.25 [25-64]years. The majority of them had been driving for more than 5 years (93.33%). Drivers spent an average of more than 8 hours (93.34%) driving per day and 68.52% of them drove over 160km per day. Low back pain was mechanical in 91.39% of cases. It was characterized by sudden onset in 81.73% of cases. Pain was moderate in 55.91% of drivers, evolving in acute pain in 46.24% of drivers and without radiation in 62.36% of cases. Age, education level, stress, posture, condition of motorcycle shock absorbers were associated with low back pain in these motorcycle drivers (p < 0.001). By contrast, distance travelled, job duration, seniority and road conditions were not associated with the occurrence of low back pain. CONCLUSION: low back pain is a serious public health problem in particular among motorcycle drivers in our country where riding a motorcycle is becoming more and more a work to bring assistance to the population facing growing unemployment. Hence the need to address factors associated with effective prevention.

Poor maternal anthropometric characteristics and newborns' birth weight and length: a cross-sectional study in Benin.

Background: Maternal undernutrition is known to negatively impact newborns' birth weight and length, but this finding is poorly documented in the Beninese population. This study aimed to assess the effect of maternal anthropometry on mean birth weight and length in a Beninese cohort of newborns. Methods: A cross-sectional study was carried out in Tori Bossito, Republic of Benin. Pregnant women attending maternity wards between June 2007 and July 2008 were recruited. At delivery the women's characteristics, including weight and height, were gathered and newborns' birth weights and lengths were measured. Statistical analysis was performed using multiple linear regression. Results: A total of 526 mother-infant pairs were enrolled; 29.8% of women had low weight status and 26.2% had short stature (<155 cm). The mean birth weight was 2985 g (standard deviation [SD] 384) the mean birth length was 48.7 cm (SD 2.2). Maternal low weight status (coefficient=-151.81, p<0.001) and short stature (coefficient=-135.49, p<0.001) reduced the mean birth weight. Similar results were found for mean birth length, which was decreased by maternal low weight status (coefficient=-0.42, p=0.04) and short stature (coefficient=-0.51, p=0.01). Conclusion: Maternal undernutrition expressed by low anthropometry remains problematic in the Beninese population and induces transmission of malnutrition. Nutritional interventions are required to break this vicious cycle.

A cross-sectional study with an improved methodology to assess occupational air pollution exposure and respiratory health in motorcycle taxi driving.

INTRODUCTION: Motorcycle taxi driving is common in many African cities. This study tested whether this occupation is associated with more respiratory disorders in a context of widespread urban air pollution with an improved methodology. METHODS: In a cross sectional study we compared 85 male motorcycle taxi drivers in the capital city of the Republic of Benin (Cotonou) with an age and neighborhood matched control group. All participants carried a portable carbon monoxide data logger for 8 hours per day to assess exposure to air pollution. Respiratory symptoms were obtained using a standardized questionnaire and pulmonary function was assessed by spirometry. RESULTS: The two groups did not differ significantly (p>0.10) in their age, height, educational level, and exposures to smoke from biomass fuels and tobacco products. The taxi drivers were exposed to higher mean (SD) levels of carbon monoxide (7.6±4.9ppmvs. 5.4±3.8ppm p=0.001). They reported more phlegm and tended to have slightly lower levels of lung function, although these differences were not statistically significant. CONCLUSION: In this cross sectional study of young motorcycle taxi drivers with substantial exposure to urban traffic and a matched control group, we found no evidence for respiratory impairment. A follow-up of such study population with other pollution exposure surrogate and other clinical endpoint may provide a more robust conclusion regarding the exposure response in this professional group.

Occupational and Environmental Health Risks Associated with Informal Sector Activities-Selected Case Studies from West Africa.

Most in the Economic Community of West African States region are employed in the informal sector. While the informal sector plays a significant role in the region's economy, policymakers and the scientific community have long neglected it. To better understand informal-sector work conditions, the goal here is to bring together researchers to exchange findings and catalyze dialogue. The article showcases research studies on several economic systems, namely agriculture, resource extraction, transportation, and trade/commerce. Site-specific cases are provided concerning occupational health risks within artisanal and small-scale gold mining, aggregate mining, gasoline trade, farming and pesticide applications, and electronic waste recycling. These cases emphasize the vastness of the informal sector and that the majority of work activities across the region remain poorly documented, and thus no data or knowledge is available to help improve conditions and formulate policies and programs to promote and ensure decent work conditions.
