Abstract

Introduction: globally, 90% of occupational disease are under-diagnosed and only 15% of workers access occupational health services (OHS). Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death world-wide and 15% is linked to occupational exposure. Cement factory workers are at risk of developing COPD and require optimal OHS but prevalence is unknown in Nigeria. We determined the prevalence of COPD and assessed OHS in a cement factory in Nigeria.

 

Methods: we conducted a comparative cross-sectional study. Operations workers exposed to cement dust and administrative unexposed were recruited. We used stratified sampling to select non-smokers with five years’ minimum work duration from both groups. We conducted a walk-through survey to assess OHS. Standard questionnaire was used to determine occupational history, respiratory symptoms and personal protective equipment (PPE) use. We defined COPD using the highest of three spirometer readings as FEV1/FVC ratio ≤ 0.7 with respiratory symptoms. Univariate and bivariate analysis were determined.

 

Results: of the 200 selected workers, 100 were from operations. The mean age and work duration were 35 ± 10.2 and 18 ± 6.6 years. The overall prevalence of COPD was 22% with higher values 36 (36%) in exposed compared to 18 (18%) in unexposed (p < 0.05). Only 20% of workers had ever had spirometry test. Cough was the most reported symptom 60/200 (30%) and the risk was twice higher among non-users of face mask than users (OR 2.3, 95% C.I = 1.3 - 1.5). About 80% of workers reported poor fitting as limitation to PPE use. Walk-through showed visible dust from inefficient dust control machine in operations which was more than 5km away from administrative department.

 

Conclusion: the higher prevalence of COPD in operations workers than administrative justifies optimal OHS such as efficient dust control measures and provision of appropriate PPE. Referral of workers with COPD for expert management and modification of job tasks were public health actions instituted.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nigeria CDC/Nigeria Field Epidemiology and Laboratory Training Programme 2<sup>nd</sup> Annual Scientific Conference (Abuja)

To create a platform for epidemiologists and public health physicians to share their scientific works, NCDC/NFELTP organized the 2nd annual scientific conference with the theme "strengthening one health through field epidemiology training" at Transcorp Hilton Hotel, Abuja, Nigeria from July 5-7, 2017. The objectives of the conference were to provide residents and graduates a forum to share findings from their field activities; provide training opportunity for trainees on scientific communication; provide an opportunity for epidemiological networking as well as create a forum to discuss pertinent public health issues. In attendance were dignitaries from the United States Centers for Disease Control and Prevention (CDC), USAID, WHO, Africa CDC, Ministries Departments and Agencies, University officials and other implementing partners. With the current rise in zoonotic diseases, the conference also featured a two-day pre-conference workshop on One Health which prioritized zoonotic infectious diseases in Nigeria using standardized prioritization methods. A second workshop focused on antimicrobial resistance. There were 38 oral presentations, 60 poster presentations and 2 plenary sessions. The presentations covered various sub-themes ranging from outbreak investigations, case management, health system strengthening, vaccine preventable diseases, communicable diseases and surveillance. The conference featured a National Night and climaxed with awards to outstanding presenters.
