Relationship between pulmonary function and peripheral vascular function in older Chinese: Guangzhou biobank cohort study-CVD

Table 2 Association (regression coefficient β, 95% confidence interval) of pulmonary function with baPWV and ABI in all participants

	Unadjusted β (95% CI)	P	Adjusted β (95% CI)	P
baPWV (dependent variable)
FEV₁% predicted	−3.02 (−3.91 to −2.13)	< 0.001	−0.95 (−1.70 to −0.20)	0.01
FVC% predicted	−4.34 (−5.34 to −3.35)	< 0.001	−1.16 (−1.98 to − 0.35)	0.005
FEV₁ /FVC ratio	−5.87 (−8.02 to − 3.71)	< 0.001	0.53 (− 1.27 to 2.33)	0.91
ABI (dependent variable)
FEV₁% predicted	0.03 (0.001 to 0.05)	0.045	0.02 (−0.01 to 0.04)	0.32
FVC% predicted	0.03 (−0.002 to 0.06)	0.06	0.02 (−0.01 to 0.05)	0.18
FEV₁ /FVC ratio	0.02 (−0.04 to 0.08)	0.54	−0.005 (− 0.10 to 0.09)	0.92

baPWV brachial-ankle pulse wave velocity (greater variables indicate greater stiffness), ABI ankle-brachial index (lower variables indicate greater stiffness), FEV₁ forced expiratory volume in 1 s, FVC forced vital capacity
Adjusted for age, sex, education, smoking, physical activity, waist circumference, diastolic blood pressure, triglycerides, fasting plasma glucose, chronic obstructive pulmonary disease, asthma and medications (aspirin and/or lipid lowering medication)
