Clinical effects of blood pressure biofeedback treatment on hypertension by auto-shaping.

OBJECTIVE: Although biofeedback has been reported to be efficacious in the treatment of hypertension, the degree of response has varied. This study investigated the mechanisms of blood pressure reduction by biofeedback. METHOD: Thirty outpatients with essential hypertension (10 men and 20 women) aged 38 to 65 years were studied. Subjects were randomly assigned to group A or B. Subjects in group A underwent biofeedback treatment once a week for a total of four sessions. Those in group B self-monitored their blood pressure during the sessions as the control period and later underwent the same biofeedback treatment. RESULTS: Blood pressure measured by doctor was reduced by 17 +/- 18/8 +/- 7 (p < .01) and elevation of pressure induced by mental stress testing was suppressed by 8 +/- 9 (p < .05)/4 +/- 8 during the treatment period in group A (mm Hg). In group B, both blood pressure measured by doctor and elevation of pressure by mental stress testing remained unchanged during the control period and they were later suppressed by 20 +/- 15/9 +/- 7 (p < .01) and 11 +/- 10(p < .05)/5 +/- 9 by the biofeedback treatment. Self-monitored pressure in both groups tended to decrease by the biofeedback treatment. Systolic and diastolic pressures as well as pulse rate decreased, skin temperature increased, and alpha-wave amplitude on electroencephalography increased during the therapy (p < .05). CONCLUSION: This treatment was effective in suppressing the pressor response to stress. Patients whose blood pressure increases with stress may be suited for biofeedback intervention.

Stressful life events and smoking were associated with Graves' disease in women, but not in men.

OBJECTIVE: Although psychological stress and smoking have been proposed as contributing factors to Graves' disease, their independent roles in the pathogenesis of this disease have not been determined. We assessed the association between Graves' disease and psychological stress and smoking by using multivariate analysis. METHODS: By a matched case-control method, we investigated the association between Graves' disease and stressful life events, daily hassles, smoking, drinking habits, coping skills, and social support in 228 patients (182 women and 46 men) with newly diagnosed Graves' disease; we used the conditional maximum likelihood method. RESULTS: After data were adjusted for daily hassles, smoking, drinking habits, social support, and coping skills, we found that stressful life events were significantly associated with the risk of Graves' disease in women. The relative risk was 7.7 for women with the highest stress score compared with women with the lowest stress score (95% confidence interval, 2.2 to 27, p for trend < .001). Smoking was also independently associated with the risk of Graves' disease in women. The relative risk for women with the highest number group compared with women with the lowest number group for smoking cigarettes was 5.1 (95% confidence interval, 1.0 to 27; p for trend < .001). These factors were not significantly associated with Graves' disease in men. CONCLUSIONS: Psychological stress and smoking were associated with Graves' disease in women, but not in men.

Psychosocial factors influencing the short-term outcome of antithyroid drug therapy in Graves' disease.

OBJECTIVE: Although psychological stress and smoking have been proposed as factors contributing to Graves' disease, their independent roles in the course of this disease have not been determined. We assessed the association between the course of Graves' disease and psychosocial factors by using multivariate analysis. METHODS: We investigated the association between the short-term outcome of Graves' disease (assessed 12 months after the beginning of antithyroid drug therapy) and stressful life events, daily hassles, smoking, drinking habits, coping skills, and social support (before and 6 months after beginning therapy) in 230 patients (182 women and 48 men) with newly diagnosed Graves' disease, using a logistic regression model. RESULTS: After adjustment for smoking, coping skills, and thyroid function, daily hassles scores in women at 6 months after beginning therapy were significantly associated with a hyperthyroid state 12 months after beginning therapy. The relative risk was 3.9 for women with higher daily hassles scores compared with women with lower daily hassles scores (95% confidence interval, 1.1 to 13.2; p < .05). Smoking was not significantly associated with a hyperthyroid state 12 months after beginning therapy in either women or men. CONCLUSIONS: Chronic psychological stress is associated with the course of Graves' disease in women.
