1. Hailemariam, Mamo. Cardio-respiratory Function among Cobble Stone Workers in Addis Ababa, Ethiopia .

Degree: 2013, Addis Ababa University

Background: Globally, an estimated 2.34 million people die from work-related accidents and diseases annually and 6,300 people die daily (ILO, 2013). Cobblestone work is becoming a good job opportunity in Ethiopia but it exposes workers to dust during excavating, cutting, drilling, handling, loading, transporting, chiseling and paving activities. Stone dust exposure has effect on the cardio-respiratory, liver and kidney functions with its associated symptoms as it contains metals and other substances risky for human health. Dust exposure is also associated with increased BP, reduced HR variability, increased HR, endothelial dysfunction and myocardial coronary heart disease. It induces pulmonary and systemic inflammation,accelerating atherosclerosis and altering cardiac autonomic function. Objectives: The present study was designed to determine the prevalence and types of cardiorespiratory problems associate with effect of exposure to cobblestone dust.It was also intended to investigate acute effects of cobblestone dust exposure on cardiopulmonary function in addition to assessing the awareness of cobblestone workers about dust effect on health and practice of PPDs. Materials and Methods: Comparative cross-sectional study and systematic random sampling was applied selecting 155 (82 chiseling and 73 quarry) workers who were 18-35 yrs old and exposed for one and above years. Twenty three of them were female chiseling workers. One hundred fifty one matched controls (128 males,23 females) were selected from AAU summer non- smoking normal students within the same age range. Acute exposure standard was established on an eight-hour exposure time frame, during work of normal intensity and data were collected at the early morning and after exposure for about 8-10 hours. Lung function indices, HR, %SPO and ABP were taken before and after exposure. The mean ages, height, weight and sex proportion were matching between the two groups. Questionnaire, digital spirometer, pulse oximeter, sphygmomanometer, digital balance and measuring tape were used for data collection. Results: The study showed higher prevalence of cardio-respiratory symptoms and changes in cardiopulmonary function indices. The mean values and percent predicted mean values of lung functions (FVC, FEV1, FEV1/FVC, PEFR, PIFR and FEF25-75) were significantly reduced (p< 0.05). The mean value of %SPO was reduced significantly (p=0.030) in exposed groups compared to control. The mean value´é▒SD of heart rate in exposed groups showed very significant increment (p=0.001) and reduced variability compared to the controls. Both systolic blood pressure (p=0.006) and diastolic pressure (p=0.001) showed very significant increment. Symptoms and reduction in lung function indices were more marked in chiseling workers. Neither control nor exposed group has had restrictive pattern alone; about 18.1% and 17.4% of cobble stone workers were found to have obstructive and mixed condition, respectively.
