Abstract
The object of this study is to estimate the pervalence of rhinitis symptoms amongst textile workers and individual prevention practices currently used by workers in textile factories in Vietnam. A cross-sectional study was conducted in two textile garment companies in the Nam Dinh province of Vietnam from May to October 2016. A total of 1082 workers in all stages of the textile production process participated in the study. Itchy nose and sneeze were the most common symptoms (with 46.9% and 46.9%, respectively, followed by itchy (33.2%) and runny nose (24.5%). Duration of cotton dust exposure per day were positively associated with face mask use (OR=1.90; 95% CI= 1.24 - 2.90) regular face mask use (OR=2.5; 95% CI=1.87 – 3.33) and nasal spray before working (OR=4.2; 95% CI=1.49-11.83). A high pervalence of allergic OR is observed amongst textile workers in Vietnam highlighting the need for preventive measures to reduce exposure to cotton dust.

We examined the time of cotton dust exposure per day and whether the workers suffered from allergic rhinitis or not
Summary
The nasal passageway and the respiratory tract is a main point of entry for foreign substances into the body. The nasal fossa is often the first point of contact to inhaled agents including gases, vapors, and aerosols (Dantas, Valera, Zappelini, & Anselmo-Lima, 2013). Exposure to an array of irritants and allergens in the environment can elicit an inflammatory response. When the nasal mucosa is exposed to a noxious stimuli, it can respond with vasodilation, increased vascular permeability, nervous sensory stimulation, and gland stimulation causing symptoms of rhinitis including nasal congestion, itching, sneezing, and rhinorrhea (Moscato et al, 2008). In addition to irritants and allergens, rhinitis can be be caused by viruses and bacteria (Moscato et al, 2008).
