Respiratory symptoms and pulmonary function among wood dust-exposed joss stick workers

Background: Most workers of carpet factory and sawmills suffer from non-specific lung diseases and ventilatory disorders. There is so many such industries operative in Lalitpur district and so far not many studies have been reported on pulmonary function in these workers. Method: A brief clinical sheet regarding age, occupational particulars, smoking habits and presence or absence of major complaints was recorded for each worker. Spirometric parameters were recorded using an electronic (MEDSPIROR) spirometer. The groups consisted of control subjects not exposed to industrial dusts (n=50) for each group of workers (carpet factory, n=50 and saw mill, n=50). Result: This study indicated an overall reduction in pulmonary function parameters; in particular FVC, FEV1 and FEV1/FVC % in carpet factory workers and FEV1 and FEV1/FVC % in saw mill workers. Comparison of pulmonary function parameters between carpet factories workers and sawmill workers revealed a significant reduction in FEV1 and MVV in carpet workers. Conclusion: Exposure to cotton dust and wood dust leads to combined type of spirometric deficit revealing obstructive or restrictive lung diseases. Workers exposed to industrial dusts also suffer from various upper or lower respiratory symptoms.

Abstract Background Subjects with chronic respiratory symptoms and preserved pulmonary function (PPF) may have small airway dysfunction (SAD). As the most common means to detect SAD, spirometry needs good cooperation and its reliability is controversial. Impulse oscillometry (IOS) may complete the deficiency of spirometry and have higher sensitivity. We aimed to explore the diagnostic value of IOS to detect SAD in symptomatic subjects with PPF. Methods The evaluation of symptoms, spirometry and IOS results in 209 subjects with chronic respiratory symptoms and PPF were assessed. ROC curves of IOS to detect SAD were analyzed. Results 209 subjects with chronic respiratory symptoms and PPF were included. Subjects who reported sputum had higher R5–R20 and Fres than those who didn’t. Subjects with dyspnea had higher R5, R5–R20 and AX than those without. CAT and mMRC scores correlated better with IOS parameters than with spirometry. R5, R5–R20, AX and Fres in subjects with SAD (n = 42) significantly increased compared to those without. Cutoff values for IOS parameters to detect SAD were 0.30 kPa/L s for R5, 0.015 kPa/L s for R5–R20, 0.30 kPa/L for AX and 11.23 Hz for Fres. Fres has the largest AUC (0.665, P = 0.001) among these parameters. Compared with spirometry, prevalence of SAD was higher when measured with IOS. R5 could detect the most SAD subjects with a prevalence of 60.77% and a sensitivity of 81% (AUC = 0.659, P = 0.002). Conclusion IOS is more sensitive to detect SAD than spirometry in subjects with chronic respiratory symptoms and PPF, and it correlates better with symptoms. IOS could be an additional method for SAD detection in the early stage of diseases.

Background Wood furniture manufacturing factory workers are at high risk of exposure to wood dust in wood working processes. Wood dust exposure could cause respiratory symptoms, such as reduce lung function, chronic bronchitis, and asthma. The Northeast region of Thailand has many wood furniture manufacturing factories. However, limited studies were carried out to explore the effect of wood dust exposure on workers.Objective This study aimed to assess the respiratory symptoms and determine factors associated with these symptoms among wood furniture manufacturing factory workers.Method This cross-sectional analytical research used a multistage random sampling to select 511 workers from three provinces in the Northeast of Thailand. The data was collected using a structured questionnaire interview. The content validity of questionnaire was tested by 3 experts and had a Cronbach’s alpha coefficient of 0.82. Data were analyzed using descriptive statistics and multiple logistic regressions.Result The result indicated that 29.94% of these workers had respiratory symptoms, including coughing(18.79%), nasal secretion (15.66%), and stuffy nose (15.07%). Factors that were significantly associated with respiratory symptoms (p–value<0.05) were (a) not always wearing mask (adjusted OR=2.26;95% CI=1.37-3.72), (b) low to medium level of knowledge on dust prevention (adjusted OR=1.83;95% CI=1.23- 2.73) and (c) contacted softwood dust (adjusted OR=1.97;95% CI= 1.06-3.64).Conclusion About 30% of wood furniture manufacturing factory workers had respiratory symptoms with related to both personal preventive behaviors and their working environments. Therefore, the raising awareness for using personal protective equipment during work will help them to prevent from various respiratory track problems.

Cooking Fumes

The cooking process may emit toxic compounds and airway irritants from both the fuel combustion and cooking fumes which is harmful to the respiratory health among the restaurant workers. A cross-sectional study of 243 restaurant workers from the selected restaurants in Sungai Long, Malaysia was conducted. The standardized British Medical Research Council questionnaire on Respiratory Symptoms (1986) was used during the interview to access the symptoms and the spirometry test was performed to evaluate the pulmonary functions of the participants. The data of socio-demography and occupational characteristics were also collected. The most complaint respiratory symptoms by the restaurant workers were breathlessness, which accounted for 33.7%, followed by wheezing (14%). The mean values of all pulmonary function tests (PFT) of the restaurant workers were within the normal range (>80%), except for the Peak Expiratory Flow (PEF) (79.09%). The results of the bivariate statistical analysis, Chi-square, ANOVA and t-test, showed the determining factors of the respiratory health among the workers were workers’ age and gender in addition to the working duration and the ethnicity. The restaurant workers in Sungai Long were at risk of developing respiratory symptoms and lower pulmonary function values due to prolonged exposure to cooking fumes. Emphasis should be given to the safety and health of restaurant workers and health education should be provided to the restaurant workers and owners. Strategies to increase notification of such occurrences among these workers should be looked into by related agencies in the country.
