Participating in a laboratory study of the effects of stress on eating, healthy, nonsmoking men and women were shown a film about industrial accidents (stress condition) or a pleasant travelogue (control condition) and had access to sweet, salty, and bland snack food. Analyses of food consumption data revealed a significant interaction between sex of subject and the stress manipulation: Stress markedly and significantly decreased food consumption by men but resulted in some increased food consumption by women. Across the three food taste categories, men consistently ate less under stress than they did in the control condition. In contrast, women ate nearly twice as much sweet food and more bland food under stress than they did in the control condition, but these effects were not statistically significant. These results indicate that the relationship between stress and eating depends on the sex of the subject and may relate to type of food available. Contrasting generalizations about stress and eating reported in the archived literature can largely be reconciled by considering these interacting variables. 相似文献

Among 383 participants in a longitudinal study of myocardial infarction (MI) patients, 230 smoked at the time of the MI. Posthospital smoking status was based on self-report for the day of follow-up, whereas information about length of continuous cessation was not available. Six months after the heart attack, 40.6% of the smokers had resumed smoking, whereas 49.4% smoked at a 3- to 5-year (M = 43-month) follow-up. Resumption of smoking within 6 months after the heart attack was associated with an increase in anxiety and depression during the first weeks after discharge, less cardiac health knowledge, and a less severe MI. In patients who relapsed at a later point, resumption of smoking was associated with a subsequent decline in general cardiac health knowledge, as well as in correct understanding of smoking at a risk factor. Long-term changes in smoking status were also related to previous heart disease, premorbid work instability, age, and severity of the MI. The results indicate that antismoking counseling of MI patients should not be limited to the health risks associated with smoking and that training in coping with negative affects without smoking may be valuable in promoting smoking cessation. 相似文献

O’Brien maintains that the behavior of football fans should be analyzed not merely in terms of individual behavior but also in terms of group dynamics. He found in the Milltown Supporters Club several such groups. 相似文献
