COPD : Spirometry-based estimates of COPD prevalence in a number of countries for men, women and total

Spirometry-based estimates of COPD prevalence (%) for men (m), women (f) and total (t) in a number of countries (source: Halbert et al., 2003)

	Diagnostic criteria	Age (yr)	COPD prevalence
			m	f	t
Denmark^a	FEV1/FVC<70%, FEV1<60% predicted	20-90			3.7
England ^b	FEV1	60-75			9.9
Finland ^c	Clinical examination plus spirometry	65	12.5	3.0
Finland ^d	Clinical examination plus spirometry	30	22.1	7.2
Finland ^d	FEV1/FVC=69%	30	11.0	5.2
Italy ^e	ERS spirometric criteria	25	12.5	11.8	11.0
Spain ^f	FEV1/FVC<70%, FEV1<80% predicted	40-60	6.8
Spain ^g	ERS spirometric criteria plus reversibility test	40-69	14.3	3.9	9.1

FEV1 = Forced Expired Volume in 1 second, FVC = Forced Vital Capacity

Remarks

These are the spirometry-based estimates of COPD in countries available from the Halbert et al., 2003 study. This study has recently examined the reliability of the COPD prevalence data worldwide.
