Table 2. Linear regressions (ß) of BMI on cardiovascular parameters at rest and their changes in response to stress.

	Rest	Δ Stress 1	Δ Stress 2	Δ Recovery
HR (bpm.unit⁻¹)	0.17	−0.50^**	−0.51^*	0.08
SV (mL.unit⁻¹)	0.32	−0.33^*	−0.42^**	−0.15
CO (mL.min⁻¹.unit⁻¹)	39	−61^**	−74^**	−2
TPR (WU.unit⁻¹)	−0.054	0.108^*	0.132^*	0.075
Compliance (mL.mmHg⁻¹.unit⁻¹)	−0.0038	0.0034	0.0028	0.0051
SBP (mmHg.unit⁻¹)	0.81^**	−0.41^*	−0.32^*	−0.14
MBP (mmHg.unit⁻¹)	0.43^*	−0.31^**	−0.29^**	0.06
DBP (mmHg.unit⁻¹)	0.28	−0.19	−0.14	0.09

Changes for the stress and recovery periods were calculated with respect to rest. Associations were adjusted for age and sex. Note that mean TPR and compliance fell in response to stress. Therefore, positive associations of these two measures with BMI indicate smaller responses. ^* P<0.05, ^** P<0.01.
