Exposure to occupational dust and changes in pulmonary function among cobblestone paving workers of Jimma, Ethiopia

Abstract: The classic diseases of "dusty" occupations may be on decline, but they are not yet extinct. Studies have found associations between changes in ambient particulate air pollution and increased cardiorespiratory morbidity and mortality. A cross-sectional comparative study design was employed on 127 male nonsmoker cobblestone paving workers and 194 matched employed office workers as a reference in order to assess changes in pulmonary function related to dust exposure among cobblestone road paving workers of Jimma… Show more

“…This was consistent with findings by Isara et al [10] among workers exposed to quarry dust in Edo state, Nigeria and Draid et al on quarry industry workers in Libya [11]. The same results were obtained by similar studies [14][15][16]. The study indicated that the FVC and FEV1 values in the dust exposed groups were significantly reduced, and considering that there was no significant difference in the variables affecting the spirometry (gender, age, height, weight, work experience), this reduction could be attributed to the dust in the workplace.…”

“…Despite there is no study conducted on the interested area in the setting and as well as in the country, there are different studies conducted among woodworkers to evaluate the magnitude of respiratory symptoms globally [3,5,8,[11][12][13][14]. Previous study conducted in the setting among woodworkers reported higher magnitude of respiratory disorders than the control group [37] and also study done among cobblestone road paving workers revealed the significant higher odds of respiratory symptoms, (dry cough (p < 0.05), cough (p < 0.01) and sore throat (p< 0.001)) compared to the reference group [38]. Study conducted among street sweepers in Addis Ababa showed the high prevalence respiratory symptoms [39].…”

“…Forced expiratory volume at one second (FEV 1 ): The Volume of air exhaled in the first second during an FVC effort was also measured in a litter (L), the SMD of FEV 1 at 95% CI was −0.54(−0.72,−0.36) in seven studies the FEV 1 showed a decreased FEV1 in cases as compared to the controls 1,2,4,13,14,22,24 . The SMD of FEV 1 of four studies 9–11,25 showed a decreased FEV 1 in cases as compared to controls, and two studies did not show a significant change in cases and controls 12,23 (Figure 5).…”
