Abstract
During the manufacturing process at carbon black industry, incomplete combustion of carbon containing materials at high temperature releases a lot of gaseous by-products and pollutants such as: CO, SO2 and PAHs. Studies revealed significant association between these exposures and development of CHD.
Prediction of CHD risk is a very important step for prevention of the disease. However, studies which examined the prediction of CHD risk at carbon black industry are insufficient. Thus, the current study was conducted aiming at assessing a 10- year CHD risk among workers at a carbon black factory in Alexandria. The specific objectives of the study were: 1) identify sociodemographic characteristics of workers at carbon black factory; 2) calculate FRS for estimation of a 10-year CHD-risk among workers at carbon black factory; and 3) study the association between exposures at carbon black factory and 10-year CHD-risk.
For fulfillment of these objectives, a cross-sectional descriptive approach was adopted. All registered workers at the studied factory who agreed to participate in the research were included (n=271); 154 workers were exposed to emissions of incomplete combustions of carbon-containing materials, while 117 workers were not exposed to that emissions. All workers in the study were subjected to: 1) interview questionnaire to collect data about sociodemographic, occupational and medical characteristics; 2) anthropometric measurements; 3) blood pressure measurement; 4) lipid profile measurement; and 5) calculation of FRS for prediction of 10-year CHD risk.
In the current study, regarding sociodemographic and occupational characteristics of the studied workers: there was no statistical significant difference between exposed and non-exposed workers as regard their age, residence, marital status and work duration. Regarding smoking status, 55.2% of exposed workers were smokers compared with 35% of non-exposed workers, the difference was statistically significant (p <0.01). However, among smokers in the current study (n =126), there was no statistical significant difference between exposed and non-exposed workers regarding their smoking index (p =0.08).
