“…The overall prevalence of chronic respiratory symptoms in this study (54%) was comparable to previous research conducted in similar low-and middle-income settings such as in Ethiopia (48%) [30], Egypt (59%) [9], Nigeria (62%) [11], and Bangladesh (53%) [31]. However, the prevalence was higher than the study conducted in an Iranian textile factory (26%), where workers were relatively younger [16].…”

“…The highest average inhalable dust exposure level was recorded in the carding section in the spinning department [26]. In a similar study, a higher cross-shift reduction was reported in spinning [15,16]. However, in our study, a high prevalence of chronic respiratory symptoms, but with the lowest cross-shift reduction, was found in the finishing department.…”

“…Cross-shift reduction in lung function has previously been reported among textile workers in other countries [15,16]. In a Shanghai textile cohort, the result of three surveys indicated a larger cross-shift ∆FEV1 decrease among exposed cotton workers (48-58 mL) compared to controls (6-26 mL) [17].…”

Chronic respiratory symptoms and reduction in lung function has been described as a common health problem among textile workers in low- and middle-income countries. The objective of this study was to measure lung function and respiratory symptoms among workers from an integrated textile factory. A comparative cross-sectional study design with a cross-shift lung function measurement was performed in 306 cotton dust exposed workers from an integrated textile factory and 156 control workers from a water bottling factory. An integrated textile factory typically has four main production departments (spinning, weaving, finishing, and garment) that process raw cotton and manufacture clothes or fabrics. Respiratory symptoms were assessed by adopting the standard American Thoracic Society questionnaire. Descriptive statistics and logistic and linear regression analysis were used. The prevalence of respiratory symptoms was significantly higher among textile workers (54%) than in controls (28%). Chronic cough, chest tightness, and breathlessness were significantly higher among textile workers (23%, 33%, and 37%, respectively) than in the control group (5%, 17% and 6%, respectively). Breathlessness was the most prevalent chronic respiratory symptom with highest adjusted odds ratio 9.4 (95% CI 4.4–20.3). A significantly higher cross-shift lung function reduction was observed among textile workers (123 mL for FEV1 and 129 mL for FVC) compared with the control group (14 mL for FEV1 and 12 mL for FVC). Thus, workers’ respiratory health protection programs should be strengthened in textile factories.

“…16,17 Elevated FeNO levels are associated with increased respiratory complaints in cotton mill workers. 18 Furthermore, increased respiratory symptoms and pulmonary function abnormalities are higher in cotton workers compared with matched controls. 19 Therefore, cotton dust plays an important role in initiation of respiratory health problems.…”

Fractional exhaled nitric oxide and respiratory complaints in Hajj pilgrims wearing a cotton towel or plain cotton ihram

Objective Hajj is an important component of Islam. This study aimed to determine the effect of wearing a cotton towel or plain cotton ihram on the onset of respiratory symptoms and fractional exhaled nitric oxide (FeNO) levels in Hajj pilgrims. Methods One hundred male nonsmoking subjects (age: 20–60 years) without a previous clinical history of respiratory illnesses were included. Fifty subjects were dressed in a cotton towel ihram and 50 wore a plain cotton ihram (control group). Respiratory symptoms and FeNO levels were recorded on the day before leaving for Hajj, when ihrams were removed, and when the pilgrims had returned home. Results Pilgrims who wore cotton towel ihrams showed significantly higher rates of respiratory symptoms, including being generally ill, coughing, a sore throat, and a runny nose, than those who wore plain ihrams. FeNO levels also tended to be higher in pilgrims who wore a cotton towel ihram compared with those with a plain cotton ihram during and after Hajj. Conclusions Hajj pilgrims who wear cotton towel ihrams may have a risk of respiratory symptoms, including a cough, sore throat, and runny nose. Therefore, a plain cotton ihram is advisable while performing Hajj to minimize respiratory illness.

Context: Fractional exhaled nitric oxide can be used as a biomarker of some respiratory diseases. Aims: This study was conducted to compare exhaled nitric oxide in cigarette and water-pipe smokers with nonsmokers. Methods: This cross-sectional study was conducted on 549 adult subjects as a sub-study of Shahedieh cohort in Yazd. Participants were divided into 5 groups according to their smoking habits: non-smokers (n = 202), cigarette smokers (n = 121), water-pipe smokers (n = 129), cigarette ex-smokers (n = 58), water-pipe and cigarette smokers (n = 39). The smokers were also categorized into heavy and light smokers. Fractional exhaled nitric oxide was compared between the groups. Statistical Analysis Used: The data were analyzed by SPSS (ver. 20) using Kolmogorov-Smirnov, Kruskal-Wallis, and Mann-Whitney U tests. Results: Fractional exhaled NO was lower in all smokers than nonsmokers, but cigarette smokers showed the least level of NO than other groups. Fractional exhaled NO was not significantly lower in water-pipe smokers than nonsmokers. Conclusions: Cigarette smoking significantly affect fractional exhaled NO, but water-pipe smoking did not significantly affect exhaled NO level.
