title: Relationship of type A behavior pattern in smokers to carbon monoxide exposure and smoking topography.
abstract: Stress-related physiological factors have been proposed to mediate the Type A behavior pattern (TABP) and coronary heart disease (CHD). However, collateral behavioral factors, such as the exaggerated consummatory response patterns of Type As, may also be involved. Study 1 examined this hypothesis by comparing exposure to cigarette smoke in 42 graduate and undergraduate student smokers assessed for the TABP. After controlling for smoking rate and Federal Trade Commission cigarette carbon monoxide yield, Type As' alveolar carbon monoxide (COa) levels were higher than Type Bs', and Jenkins Activity Survey scores were correlated with COa. To determine the source of this difference, we measured smoking topography in 10 Type As and 10 Type Bs in Study 2. Type As and Type Bs did not differ in number of puffs taken or puff volume, but Type As' inhalation duration was 70% longer than Type Bs'. These results suggest that consummatory behaviors of Type As may help account for the Type A-CHD relationship for smokers. Due to increased smoke exposure, Type A smokers may also be at greater risk for cancer and lung disease than Type B smokers.
