Association between chronic airflow obstruction and socio-economic position in Morocco: BOLD results
OBJECTIVE: To investigate the association between chronic airflow obstruction and socio-economic status in Morocco.
DESIGN: Questionnaires were administered and spirometry tests performed as part of the BOLD (Burden of Obstructive Lung Disease) Study carried out in Fez, Morocco. Socio-economic status was evaluated using a wealth score (0–10) based on household assets. The ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) was used to measure airflow obstruction.
RESULTS: A total of 760 subjects were included in the analysis. The mean age was 55.3 years (standard deviation [SD] 10.2); the average wealth score was 7.54 (SD 1.63). After controlling for other factors and potential confounders, FEV1/FVC increased by 0.4% (95%CI 0.01–0.78; P < 0.04) per unit increase in wealth score. Ageing, tobacco smoking, underweight, history of tuberculosis and asthma were also independently associated with a higher risk of airflow obstruction.
CONCLUSION: Our findings suggest that airflow obstruction is associated with poverty in Morocco. Further investigations are needed to better understand the mechanisms of this association.
