Evaluation and comparison the incidence of respiratory diseases in poultry and livestock breeders in yazd

Farmers that have occupational exposed to the organic dust, bacteria, endotoxin, mites, and fungi, as well as the hazardous gases such as ammonia, sulfides, hydrogen and nitrogen oxides, may be affected by allergic asthma, non-allergic rhinitis, and organic dust toxic syndrome. This study aimed to determine the prevalence of respiratory symptoms and spirometry parameters between the two groups of livestock breeders and ranchers farmers. The cross-sectional descriptive-analytic study was performed in Yazd on a 300 agricultural men. The questionnaire includes demographic information including age, work experience, cigarette smoking, the type of agricultural activity and respiratory symptoms among farmers.  Pulmonary function tests of all farmers were performed in a sitting position after the animals were fed. Moreover, indicators of FVC, FEV1, FEV1 / FVC, PEF25-75 were measured. T-test test data for the logistic regression analysis was used.             The results showed that respiratory capacity in the poultry is less than livestock breeder's. Cough, sputum prevalence of respiratory symptoms such as shortness of breath, wheezing and rhinitis in poultry was significantly higher than those in other groups were. The highest prevalence was related to nasal allergies [(OR=5.04 (2.7-9.4)]. Respiratory symptoms increased with age exception of nasal allergies. Comparison the age group showed 3.3 increased times Cough [(OR=3.3 (1.74-6.3)] and 2.5 sputum [(OR=2.5 (1.05-6.21)] in the age group 75 to 55 years age group 34-20 years, respectively. the prevalence of respiratory symptoms was higher in smokers than non-smokers, so that the incidence of cough, sputum, shortness of breath, wheezing and rinite allergic the This group, , 64/1, 5/1, 46/1, 7/1 and 75/1 times more than non-smokers respectively but this association was not statistically significant.         Due to the high prevalence of respiratory symptoms in farmers, agricultural mechanization promotion of health knowledge of farmers by implementing appropriate training programs is necessary.
