“…Similar studies conducted in Nigeria [ 8 ] showed that flour millers recorded significantly lower mean lung functions compared with control subjects with an increased risk of developing abnormalities of lung functions and there is an association on the overall mean pulmonary function to the duration of exposure of the flour mill workers.…”

Background Flour dust in the respiratory tract affects lung function. Flour dust is a heterogeneous organic substance which can have a tendency to cause respiratory ailments. There is growing consensus on the deleterious effects of flour dust on respiratory symptoms and lung performance of flour mill workers. Methods The study design was comparative cross-sectional. A total of 54 flour mill workers who work for more than eight-hour shift per day and 54 control subjects matched for sex, age, weight, height, and area of residence were enrolled. Anthropometric measurement was done. Lung function was measured by using a digital portable spirometer (Spiro Pro) based on the ATS guidelines. FVC, FEV1, FEV1/FVC, PEFR, and FEF25% −75% were measured. Productive cough, dry cough, wheeze, and breathlessness were evaluated using BMRC questionnaire guidelines, administered through face-to-face interview. Result This study showed statistically significant reduction in the mean values of pulmonary function tests in flour mill workers as compared to their matched controls. Reduction of pulmonary function indices in study subjects was significant for FVC (4.25±0.93 vs. 5.30±0.71, p<0.001), FEV1 (3.46±0.86 vs. 4.50±0.72, p<0.001), PEFR (5.43±2.43 vs. 7.87±2.53, p<0.001), and FEF25% −75%, (3.87±1.61 vs. 4.60±1.60, p<0.05), but not significant for FEV1/FVC (81.93±12.74 vs. 83.40±12.50, p>0.05). Flour mill workers developed 27.7% of restrictive type and 11.1% of obstructive type of lung disorders. Percentage prevalence of respiratory symptoms was evaluated as dry cough (27.7% vs. 9.3%), productive cough (11.1% vs. 5.6%), wheeze (14.8% vs. 3.8%), and breathlessness (16.6% vs.7.4%) in flour mill workers and controls, respectively. Conclusion Based on the results of the present study, occupational exposure to flour dust could cause respiratory dysfunction, thereby reducing lung efficiency.

“…Flour dust is a heterogeneous substance with respiratory sensitizing properties and long-term exposure to it may cause acute or chronic respiratory disease [ 8 ]. Several studies showed that prevalence of sensitization for wheat allergens and fungal a-amylase and OAD is high among workers exposed to flour dust [ 9 ].…”

“…45 Similarly, in other studies, it was found that all respiratory and allergic symptoms had a higher prevalence among bakers in comparison to the control group. 46,47 From the factors studied to find out whether it is an independent factor affecting peak expiratory flow rate was aeration of the workplace as it is known that the level of exposure affects the PEFR which in turn will be reflected on the lung function and affecting the degree of airflow obstruction and reduction in the peak expiratory flow rate. Good aeration of the workplace affects the level of exposure and consequently lung function (48).…”

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.

Pulmonary functions of wheat flour mill workers and controls in Ibadan, Nigeria

Abstract: The study concluded that wheat flour-mill workers in Nigeria are at an increased risk of developing abnormalities of lung functions compared with control subjects, and the dominant pattern of respiratory disease among them is airway obstruction.
