Abstract


Background: Smoking and exposure to workplace environmental pollutants could be associated with adverse effects on respiratory health and occurrence of allergic disorders.

Objectives: To explore the early effects of exposure to cement dust in the workplace and smoking, on the occurrence of respiratory and allergic disorders in young adults.

Design: It is a cross-sectional study, where a convenient non-probability sample was selected.

Setting: The sstudy was conducted in a cement manufacturing factory at the North of Jeddah city and at a medical college.

Sample size: One hundred subjects were studied (50 workers exposed to cement dust, and 50 subjects, not exposed to any noxious substances).

Method: Each subject was asked to fill out a personal questionnaire (to collect socio-demographic, and health data), an occupational questionnaire, and the MRC questionnaire on respiratory symptoms and smoking habit, and ISAAC core questionnaire on asthma and allergy. Anthropometric measurements and forced spirometry (before and after administration of the bronchodilator), were conducted on eachsubject. Multi-nominal Logistic regression and multiple linear regression were used. Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated. The level of significance for the study was 0.05.

Results: Smoking was significantly associated with chronic cough (OR=3.68; 95% CI: 0.99, 15.11 and p < 0.05), chronic phlegm production (OR=8.83; 95% CI: 2.33, 33.51, and p < 0.001), shortness of breath on exertion (OR=4.18; 95% CI: 1.49, 11.66, and p < 0.006), and eczema (OR=6.43; 95% CI: 1.33, 31.14, and p < 0.021). After allowing for age, height, weight and cement dust exposure, smoking subjects had significantly lower FEV1% compared to nonsmokers (Beta= -3.45%, p < 0.05). Cement dust exposure was not significantly associated with ill health.

Conclusions: Early effects of smoking are increased chronic respiratory symptoms and occurrence of eczema. FEV1% is the early affected lung function index in smokers, denoting airflow limitation. Cement exposure under the current environmental factory conditions seems to be safe.

Key words: Smoking, cement exposure, forced spirometry, allergic disorders
