ABSTRACT
Objective:
COPD is a leading cause of mortality and morbidity worldwide. Although cigarette smoking is a well-known risk factor for COPD, nonsmokers may account for one fourth to half of all cases. The Burden of Obstructive Lung Disease in Trinidad and Tobago (BOLD-TT) study objective was to measure the COPD prevalence and its risk factors in the local population aged 40 years and older. Design andMethodology:
In this cross-sectional survey participants were selected using two-stage stratified-cluster sampling to represent the national population in terms of gender, age and ethnic distributions. Quality assured spirometry and questionnaires were administered.Results:
Among the 1,104 participants, 36% reported occupational dust exposure for more than one year and about 40% of them were never-smokers. Overall 9.5% (95% CI 7.78 to 11.23%) of the studied population showed COPD, accounting for an estimated 49,170 persons (95% CI = 40,267; 58,124) in Trinidad and Tobago. The majority (60%) of the diagnosed COPD was attributable to non-smoking causes, and more than half of them reported occupational dust exposure. Multiple logistic regression analysis confirmed COPD's independent association with working in a dusty job (OR 2.05; 95% CI=1.26, 3.35).Conclusions:
Risk of COPD in the Trinidad and Tobago general population is significantly associated with occupational dust exposure which is probably contributing about one-third of current COPD burden. International studies showed that only about 15% of overall COPD could be ascribed to occupational risk factors. The higher occupational related COPD risk in the local population should be further studied prospectively.
