        Objective: The objective of this study was to assess the factors affecting to lung function among workers in rubber wood furniture in the eastern part of Thailand.

        Methods: This study employed questionnaires, wood dust sampling, and a lung functional test. A total of 685 subjects were recruited from 8 rubber wood furniture factories to assess inhalable dust exposures and perform a pulmonary function test. Stepwise multiple linear regression analysis was used for testing associations between independent variables (i.e., gender, age, height, frequency of cloth mask use, and mean dust level) and lung function (FVC, FEV1, and FEV1/FVC%).

        Results: The average age was 32 years (range: 18-60 years old). Females represented 53.6% of the workers, and 316 male workers (45.9 %) The mean wood dust exposure was 4.19 mg/m3 (SD = 2.66, range: 1.15- 13.67 mg/m3). The mean values of % predicted of FVC, FEV1, and FEV1/FVC were 84.90 (SD = 15.39), 89.96 (SD= 15.45), and 98.93 (SD =10.81), respectively. A significant negative correlation was found between mean dust exposure levels and FVC (p < 0.001). Similarly mean dust exposure levels were negatively correlated with FEV1 (p < 0.001) and FEV1/FVC% (p < 0.001). In addition, frequency of cloth mask use was moderately correlated with FEV1/FVC% (p < 0.005).
Conclusion: Wood workers who exposed to wood dust appeared to have decline in lung function, which suggests that wood dust exposures affected lung function.
