Psychosocial and biobehavioral characteristics of hypertensive men with elevated atherogenic lipids.

Epidemiologic studies demonstrated an excess risk of ischemic heart disease (IHD) among individuals who simultaneously exhibit hypertension and elevated atherogenic lipids (coronary high risk (CHR)-status). Yet, relatively little is known about factors which contribute to the development of CHR-status during early and middle adulthood. The present study explores the role of selected biobehavioral and psychosocial factors in explaining CHR-status using data from a prospective 6.5 years investigation of a cohort of 416 middle-aged (40.8 +/- 9.6 years) male blue-collar workers. Multivariate logistic regression analysis shows that overweight (odds ratio (o.r.) 4.14), smoking (o.r. 2.19), low promotion prospects at work (o.r. 2.71), competitiveness at work (o.r. 2.79) and feelings of sustained anger (o.r. 5.41) independently contribute to the explanation of CHR-status. Furthermore, the operational definition of CHR-status is validated by estimating its power in predicting IHD incidence in the study cohort. In conclusion, co-manifestation of hypertension and elevated lipids is more likely to exist among those blue-collar men who exhibit distinct work-related characteristics in addition to established biobehavioral risks such as overweight and smoking. In view of the high prevalence of CHR-status and of IHD among men in the lower socio-economic strata this finding is also of interest for health policy.

The pattern of hammer speed during a hammer throw and influence of gravity on its fluctuations.

Hammer speed at release is one of the most important factors contributing to the distance of a hammer throw. Hammer speed follows a generally increasing trend during the throw, with one fluctuation per turn. The purpose of the present paper was to quantify the influence of gravity on the speed fluctuations. Eight experienced hammer throwers were studied with three-dimensional filming methods. Instantaneous values of hammer velocity and speed were calculated from the film data. The rate of change of hammer speed due to the tangential component of gravity was computed, and integrated to calculate the accumulated contribution of gravity to hammer speed at all instants of the throw. These values were subtracted from the corresponding values of hammer speed. The amplitude of the fluctuations was reduced in the corrected speed functions, indicating a contribution of gravity to the original fluctuations. However, the fluctuations were still clearly present in the corrected speed functions, indicating the existence of other causal factors.

Interpersonal and electrocardiographic responses of Type A's and Type B's in competitive socioeconomic games.

Forty-eight subjects classified as either Type A (coronary-prone) or Type B (coronary-resistant) exchanged points worth money with a computer-simulated opponent while an electrocardiogram was computer-monitored and scored. Type A's were more aggressive during the socioeconomic exchanges than were Type B's. The more aggressive a subject during the interactions the greater was the shift toward depression of the ST segment of the electrocardiogram. Despite the relationship between aggression and ST response, and the greater aggressiveness of Type A's during the interactions, Type A's and Type B's did not differ significantly in ST response.

Goal frustration and life events in the aetiology of painful gastrointestinal disorder.

Life events and difficulties were recorded for the year preceding onset of abdominal pain in 135 consecutive referrals to three gastrointestinal clinics, and for the equivalent time period in a matched, healthy community comparison series. Fifty-six patients were found to have an organic gastrointestinal disorder. Severely threatening events and major difficulties known to play a critical aetiological role in clinical depression, occurred with much the same frequency during the 38 weeks before onset of non-organic ('functional') gastrointestinal disorder. There was no such relationship between the severity of threat and organic disorder. A measure of 'goal frustration' reflecting the degree to which the subjects aims and ambitions were insurmountably obstructed by the occurrence of the event, was significantly associated with organic disorder. This finding may explain the often reported association between life stress and organic gastrointestinal disorder.

Cynical Mistrust and the search for self-worth.

Cynical Mistrust was examined among 64 medical and surgical patients, 23 of whom were selected for a history of CHD and 41 for an absence of such a history. Cynical Mistrust was found to differentiate subjects with a positive history from those without such a history. As hypothesized, persons scoring high in Cynical Mistrust also scored high in Self-Worth by Social Comparison, Playing Hardball with Others and Self-Criticism. Surprisingly, high scorers in Cynical Mistrust among subjects with a coronary history also scored high in Dependency on others for validation that they were deserving of being loved. We suggest that the pathogenicity of Cynical Mistrust for CHD may be potentiated by the presence of certain other dispositions. Further investigation of dependency on others in particular appears to be worthwhile in order to determine whether consideration of this disposition can improve the identification of risk for CHD.
