Accidents at work as a result of deplorable conditions of safety and health at work in particular, the lack of wearing protective equipment are responsible for great suffering, significant losses for employees and their families, employers and social security funds. In addition to the knowledge of the factors explaining occupational risks and the requirements for wearing protective equipment, the world of work will enable the world of work to achieve decent work. The general objective is to improve the prevalence of injuries and their location among injured workers in the formal sector of Haut-Katanga in order to promote the health and well-being of the population of the Democratic Republic of Congo in general and that of Haut-Katanga in particular. Methods: This is a multicenter historical cohort study including all workers in the formal sector in the province of Haut-Katanga victims of accidents at work registered at the National Social Security Fund and in a mining company in the city of Lubumbashi in the province of Haut-Katanga. Results: During this first phase (2010 to 2017), 510 occupational accident files were recorded. The highest accident rate was recorded in 2012. Males account for 93.10%. The bride and groom were the most injured, accounting for nearly 91.72%. The seniority bracket ranging from 1 to 10 years was the most rugged bracket with 63.12%. The primary sector is the most rugged sector with 70.8% of which miners represent 51.5%. Workers with a primary education level are the most injured with 83%. The multivariate analysis shows that workers in the primary sector are the most injured as well as those with a seniority of less than 7 years. Subjects who had head injuries had a better cure rate. During the second phase, the study conducted in a mining company showed that out of a total of 338 workers, 14 cases of occupational accidents were recorded. 95.1% of the victims had a primary education. During this study, wounds account for a significant proportion (37.08%). Among the various injuries recorded (20.12%), those of the chest are the basis of deaths. Involvement of the limbs (lower left limb 22.09%, lower right limb 19.53%, right upper limb with 16.77%, left upper limb with 11.64%), head with 18.15% and trunk with 11.24%. As for the nature of the lesions, wounds account for a significant proportion (37.08%).

Introduction: Occupational risks resulting from deplorable safety and health conditions at work are responsible for major consequences recorded in the families of the injured, for employees as well as for social security funds. Knowledge of the psychosocial factors that may give rise to occupational risks will enable the world of work to develop a coherent occupational safety and health program and to give concrete expression to the concept of decent work.The objective of this research is to study the impact of psychosocial factors in the occurrence of occupational risks in a mining company in the formal sector in the province of Haut-Katanga.Methodology: Our exploratory descriptive study was in a mining company in Haut-Katanga Province in the Democratic Republic of Congo.-The reference population is made up of the workers of this same mining company in Haut-Katanga. These workers were divided into three sectors: mining, mineral processing and administration (support sector).-A stratified random sampling of 338 workers was carried out. The Karasek questionnaire was used for data collection.Results: Our study conducted in a mining company showed that out of a total of 338 workers.During this study, karasek’s questionnaire administered to the 338 workers showed that 258 workers were classified and 80 were not. The addition of addictive behaviors such as alcohol and tobacco consumption showed « low social support » in 83% of those classified, 84.6% had a seniority of at least 5 years and 83.1% were assigned to mining operations.A « low decision-making latitude » was perceived by 91.8% of the classified. Of this group, 89.9% had a seniority of at least 5 years and 97.3% worked in the mining operations sector. A strong psychological demand is reported by 84.8% of classified workers. Of this group, 84% had a seniority of at least 5 years and 86.8% were assigned to the mining operations sectors. The perception of low decision-making latitude was influenced by professional status and industry. Classified workers reported low latitude 2.5 times more than their unclassified counterparts.Conclusion: Psychosocial factors are a reality in our professional environment and therefore responsible for occupational risks.The control and evaluation of psychosocial factors make it possible to prevent the occurrence of occupational risks likely to cause bodily injury and socio-economic harm at different levels.

Introduction: The teaching profession in general is among the professions that impose many mental, physical, psychological and social constraints. Therefore, his environment is supposed to offer him a serene environment in order to allow him to control his health and avoid situations likely to lead to certain circumstances of many dysfunctions whose consequences deteriorate the working conditions of teachers and moreover his health. Nowadays, education is a major asset of essential societal development and as a result, the teaching profession is considered to be a job at high risk of stress, psychological risks following direct and constant contact with learners or even potentially a source of disrespectful behavior and verbal aggression, physiques etc. able to develop strong feelings of inferiority and personal failure if teachers are continually confronted with these types of stress and conflict situations that challenge their professional status, feeling attacked in their work and professional identity, and also a source of burnout. It is counted among the jobs with a significant level of social interactions such as health and social services. Objective: To determine the generating and moderating factors of occupational stress in teachers as well as the profile of blood pressure in this population. Methodology: This was a nested case-control study, conducted in the city-province of Kinshasa from October 2018 to June 2019, in six schools in the primary and secondary sectors. Two hundred and one (201) teachers participated in the study, with the M/F ratio being 2: 1. We administered the Karasek-Siegrist Occupational Stress and Effort/Reward Questionnaire as a first step. Then, after initial measurement of blood pressure by ourselves, we subjected the participants to a self-measurement of their blood pressure, after training according to the recommendations of the French Society of High Blood Pressure. We analyzed by Chi-carré de Kruss-Wallis on the IBPM-SPSS version 20 software, the results by comparing stressed teachers (cases) and controls (relaxed, active and passive subjects).Results: We found 40% of the stressed subjects that we compared to the control groups consisting of 12% of relaxed subjects, 25% of active subjects and 23% of passive subjects. Out of a total of 201 teachers, 20% had an increase in the initial BP ≥ 140/90 mmHg according to the reference values of the classification of the WHO and the European Society of Hypertension.
