“…All the factories had poor ventilation with high levels of PM 10 beyond recommended levels by WHO 10 and hence the likelihood of impairment of lung functions amongst the factory workers as was found in other related studies. 11 -12 , 13 , 14 The mean concentration of PM 10 in the factory environment breathing zones amongst those who reported cough without flu/cold was significantly higher than those who indicated otherwise this is consistent with other studies done before. 15 , 16 , 17 Respondents with chest function (FEV1/ FVC %) of less than 80 normal (a sign reduced lung function) expected value had significantly more proportion of cough without flu/cold compared to those who had FEV1/ FVC% of 80 (a sign of adequate pulmonary ventilation) and above normal, the same trend was seen in other related studies done in the past.…”

“…Symptomatically, byssinosis is a common condition due to exposure of cotton, flax, linen, and rope making dusts similar exposure to carpet industry. [29][30][31] There is occasional chest tightness in early stage and then regularly in late stages toward the end of the first day of the work week commonly known as "Monday chest tightness". In epidemiologic studies, depending on the level of exposure, up to 80% of employees may show a significant drop in their FEV 1 over the course.…”

Pulmonary Functions are Impaired among Carpet Factory Workers: A Spirometric Evaluation

et al. 2015

Introduction: Carpet factory produces various types of dusts and workers occupationally get exposed to them continuously. It has adverse health effects and most notably to the pulmonary functions. Nepal is one of the carpet exporter developing countries and still does have many factories within Kathmandu valley. However, the health hazards especially the status of pulmonary function of carpet factory workers from Nepal has not been studied.Methods: A cross-sectional comparative study was designed to recruit carpet factory workers and healthy controls to assess their pulmonary functions. A total of 118 subjects (59 males and 59 females) were recruited (60 carpet factory workers and 58 controls). Pulmonary function tests were carried out using Medical International Research Spirolab II portable spirometer.Results: The carpet factory workers had significantly less FEV1 (90.37 ±16.6 % vs. 103.89±9.79%, p<0.001), FVC (87.78 ± 15.48 % vs. 102.81 ± 8.41 %, p < 0.001) and PEFR (66.19 ± 20.29 % vs. 102.81 ± 11.09 %, p < 0.001) as compared to control group. Similarly the carpet factory workers had significantly higher FEV1/FVC ratio (89.96 ± 6.42 % vs. 87.12 ± 4.58 %, p = 0.007) as compared to control.Conclusions: Carpet industry dusts exposure adversely affects pulmonary functions among its workers. The findings significant increase in the FEV1/FVC ratio and decrease in FEV1, FVC, and PEFR suggest that the effects are both restrictive and obstructive patterns of lung disease.Keywords: carpet industry; lung function; occupational health; pollution; spirometry. | PubMed

“…Studies have shown that bakers had significantly lower forced expiratory indices than the control groups. [7][8][9] However, a study on the Egyptian population and from the aspect of occupational affecting factors and comparing those with normal to abnormal PEFR is needed to enrich the research field. Moreover, occupationally exposed workers to flour dust were found to be more likely at risk of developing nasal cavity cancer.…”

Background: Bakers face various common health problems at their work which may be aggravated when combined with improper awareness of ways of protection. Objective: The current study aimed at determining the most common symptoms encountered by bakers and to compare the peak expiratory flow rates of bakers with a control group. Method: The study included 71 bakers and 120 controls. The participants filled an interview questionnaire containing socio-demographic data as age, marital status, education, occupational background and questions about history of common diseases, body mass index was calculated, and peak expiratory flow rates were measured. Results: The mean expiratory flow rate of bakers was significantly lower than that of the control group. None of the workers reported receiving training to raise their awareness on the types of occupational disorders and methods of prevention. As regard respiratory symptoms, a significant difference was detected between groups regarding chest tightness (P=0.009) and sweating (p=0.03). Multiple logistic regression was done to identify factors associated with abnormal PEFR among bakers. After adjustment of relevant factors (age, BMI, job duration, working hours and workplace characteristics), it was found that exposure to heat in workplace was the independent factor affecting PEFR. Conclusion: The study concluded that bakery workers had various health problems related to the nature of their work and the work environment needed application of safety standards.
