Table III.

Physical activity measures of subjects with stable angina and controls. Values are means (SD).

Variables	Control Group (n = 441)	Stable Angina Group (n = 115)	Unadjusted P	Adjusted P *
Total LTPA (kcal/day)	212 (226)	144 (157)	0.003	0.016
Low Intensity LTPA (kcal/day)	64 (112)	42 (76)	0.050	0.082
Moderate Intensity LTPA (kcal/day)	127 (164)	93 (120)	0.040	0.124
High Intensity LTPA (kcal/day)	18 (47)	8 (15)	0.023	0.121
Mean Intensity LTPA (kcal/min)	4.8 (1.0)	4.7 (1.0)	0.637	0.963
Mean Duration LTPA (min/day)	47 (52)	34 (34)	0.014	0.046
Physical Activity Scale (units)	2.3 (1.5)	1.7 (1.2)	< 0.001	< 0.001

LTPA = leisure-time physical activity, kcal = kilocalories.

^*Adjusted for age, race, current smoking, diabetes, hypertension, and obesity.
