The aim of the present study was to examine the association between psychological factors and salivary cortisol secretion (baseline level, reactivity to laboratory stressors) in a sample of 59 long-term unemployed men and women (mean age 42+/-10 years). Subjects were divided into four groups according to their basal levels of salivary cortisol as well as their reactivity to experimental stress (stress level minus baseline): (1) low base/ low reactivity; (2) high base/low reactivity; (3) low base/high reactivity; and (4) high base/ high reactivity. The low base/low reactivity group was characterized by significantly higher somatic anxiety, muscular tension, irritability, and depression (Beck's Depression Inventory) and lower perceived control (mastery) than the other groups. The low base/high reactivity group was also characterized by depression and low perceived control. The high base/low reactivity group was higher in terms of monotony avoidance, Type-A behavior (JAS) and mastery, but lower in depression. The results indicate that (1) individuals with personality traits reflecting emotional distress are more vulnerable to exhaustion of the HPA-axis following long-term unemployment and (2) monotony avoidance and Type-A behavior, at least temporarily, seem to exert a beneficial influence on mental well-being among long-term unemployed individuals.

Pain perception to the cold pressor test during the menstrual cycle in relation to estrogen levels and a comparison with men.

Animal and human research has shown that pain sensitivity changes during the menstrual cycle. This has sometimes been ascribed to hormonal variations. The aim of the present study was to examine how perception of pain, induced by the cold pressor test to the dominant hand, was related to gender and phases of the menstrual cycle. A repeated-measures design was used, where twenty-two female students participated at two different phases of the menstrual cycle (days 2-4 and days 20-24). A control group of nineteen male students participated on two occasions, separated by a three week period. The cycle phase during which each woman began her participation was randomized. Pain was induced using the cold pressor test. Pain threshold was determined as the duration of time between when the subject first reported pain and exposure to the painful stimulus. Pain tolerance was determined as the duration of time until the subject withdraw her/his hand from the test water because the pain was too intensive. The results showed that men tolerated significantly greater pain than women. Women's pain threshold was significantly higher during the second phase of the menstrual cycle. Systolic pressure was higher in men than women, increasing more in men in response to cold pressor testing than women. Further research, including measurements of plasma hormone levels during the menstrual cycle, is needed to clarify the role played by estrogens in pain perception.

Associations between financial strain and the diurnal salivary cortisol secretion of long-term unemployed individuals.

OBJECTIVE: The study investigated the associations between self-rated financial strain and overall diurnal salivary cortisol levels, as well as secretory patterns among long-term unemployed individuals. METHODS: Psychosocial and life-style variables were assessed by means of questionnaires among 85 participants (mean age 42+/-9 years; 56% females). Salivary cortisol was sampled on four occasions during a 24-hour period and data was analysed separately for men and women. RESULTS: Among females, high financial strain was related to higher overall cortisol levels, and to elevated levels in the evening. These associations did not reach significance among men. Multivariate analyses showed that evening levels of cortisol were positively associated with financial strain, but largely unrelated to life-style variables and psychological distress. CONCLUSIONS: The results suggest that high financial strain influences the diurnal cortisol secretion of unemployed individuals in terms of elevated cortisol levels in the evening. The mediating mechanisms are in need of further investigation.

Sex differences in behaviour pattern and catecholamine and cortisol excretion in 3-6 year old day-care children.

Fifteen boys and eleven girls between three and six years of age were examined at a day-care center and at home as regards their catecholamine and cortisol excretion. Behaviour pattern was assessed by the MYTH-scale, which measures the competitiveness, impatience-anger and aggression components of the type A behaviour pattern in children (Matthews and Angulo, 1980). The boys obtained higher type A scores and excreted more adrenaline and noradrenaline than the girls, while cortisol excretion did not differ between the sexes. In view of previous findings, the results suggest that sex differences in catecholamine excretion in children are induced by sex related differences in behaviour. This relationship in childhood could be of relevance for sex differences in catecholamine responses observed in adulthood. In both sexes, adrenaline excretion was significantly elevated at the day-care center compared with the at-home levels, indicating that mental arousal was greater at the center. In a separate part of the study, eleven new children were tested while they were adjusting to the day-care situation; it was found that only noradrenaline levels during the first week at the center were significantly elevated.

Physiological reactivity and Type A behavior in preschool children: a longitudinal study.

Measurements of Type A behavior were related to cardiovascular (systolic and diastolic blood pressure, heart rate) and neuroendocrine (urinary catecholamines and cortisol) reactivity in 30 male and 30 female preschool children during various active conditions at their mean ages of 3.5, 4.5, 5.5, and 6.5. Significant elevations of physiological arousal occurred in most active conditions and for all physiological variables except cortisol. Playgroup leaders in daycare centers filled out a Swedish version of the scale measuring Type A behavior, and boys obtained significantly higher scores than girls. Whereas Type A scores were relatively consistent over time, however, physiological reactivity was not a stable individual characteristic, and correlations between Type A scores and cardiovascular reactivity reached significance in only 4 of 33 tests for the boys (one negative correlation) and in 1 case for the girls. Correlations between Type A scores and catecholamine reactivity did not reach significance. In summary, the data do not support the assumption of a consistent relationship between Type A behavior and physiological reactivity in preschool children. A significant correlation (r = .57, p less than .01) found for boys during a computer game suggests that an association may exist during "Type A-relevant" challenge.

Type A behavior in healthy males and females as related to physiological reactivity and blood lipids.

Type A behavior was assessed in 30 men and 30 women (ages 30-50) by a Videotaped Structured Interview (VSI). Scores for total Type A behavior as well as subcomponents (competitiveness, time urgency, hostility) were examined in relation to cardiovascular and neuroendocrine reactivity during a work day (change from a work-free day) and during laboratory-induced stress (change from resting condition). In addition, Type A and Type B males and females were compared with regard to total serum cholesterol, LDL and HDL cholesterol, and triglycerides. The results showed relationships between 1) competitiveness/hostility and physiological reactivity at work in men, 2) total Type A behavior (and hostility) and serum cholesterol in men, and 3) hostility and serum cholesterol in women. As expected, the association between Type A behavior and physiological measurements was more pronounced for "extreme" Type A and B men and women (upper and lower 10 subjects, respectively) than for the total groups of each sex.
