- One way to study the stressfulness of childbirth is to examine the output of stress hormones. In this study, urinary catecholamines and salivary cortisol from 50 primiparous women were collected for 1 day during gestational weeks 37 to 39, hourly during labor and delivery, and 2 hr and 2 days postpartum. All three stress hormones increased statistically significantly from pregnancy to labor. The increase in adrenaline and cortisol was more than 500%, and the increase in noradrenaline was about 50%. After labor, the output decreased but not statistically significantly below the levels during late pregnancy. Hormone levels during late pregnancy, during labor and delivery, and during the period postpartum mostly did not correlate systematically. However, noradrenaline and adrenaline, as well as adrenaline and cortisol, were positively correlated during labor. After administration of epidural analgesia, there was a moderate but significant decrease in noradrenaline and adrenaline, whereas cortisol did not change. In conclusion, the results of this study support the assumption that childbirth is a very stressful event and that the stress responses vary considerably among women. The substantial increase of adrenaline and cortisol compared with noradrenaline indicates that mental stress is more dominant than physical stress during labor.

- The serial Color Word Test, which is a semi-experimental way to differentiate adaptive behavior in stressful situations, was administered at baseline to men participating in the prospective cohort study "Men born in 1914". During follow-up, from 1982-1983 until December 31, 1996, 133 men experienced a myocardial infarction. Four patterns of adaptive behavior in 2 separate dimensions, the Variability and the Regression, can be discerned during testing. These patterns were compared regarding outcome following the myocardial infarction. The Cumulative-dissociative pattern of the Regression dimension was univariately associated with mortality within 28 days (OR 5.75, CI 1.85-17.88, p = .003). Dissociative (OR 3.87, CI 1.21-12.42, p = .023) and Cumulative-dissociative (OR 5.46, CI 1.66-17.96, p = .005) patterns, of the same dimension, were independently associated with mortality within one year. Specific difficulties in adaptation to stressful situations were associated with increased risk of death following a myocardial infarction. In this male sample, these difficulties could be identified with the serial Color Word Test.

- The associations were examined in women between personality traits and steroid hormones, particularly androgens, as well as polymorphisms in genes regulating androgen concentration and effects. Women, all 42 years of age and premenopausal (n = 270), were recruited randomly. Conventional "masculine" and "feminine" personality traits were examined by questionnaire and set in relation to psychosocial and socioeconomic conditions, behavior in childhood, hormones, risk factors for disease, and polymorphisms in microsatellites in the CYP aromatase and the androgen receptor gene. The proportions of personality traits considered as being dominated by "masculinity" (M) or "femininity" (F) were 44.9%, respectively 15.0%, the rest consisting of a combination of M and F (33.2%) or "undifferentiated" (6.9%). M characteristics were positively associated with education, sporting, self-confidence, and good adaptation to work situation. M scores correlated with reports of "tomboyism" as girls. There was essentially no difference in hormones or disease risk factors between M and F women. The number of (CAG) repeats in the microsatellite of the transactivating domain of the androgen receptor was 19 (2.3; M and SD). M characteristics were more pronounced in the presence of longer repeat stretches (n > 20). No associations were found with F scores. There were no significant associations to the number of tetranucleotide repeats (TTTA) in the fourth introne of the aromatase gene. It was concluded that a majority of women showed M type of personality traits, associated with normal hormones, somatic health, and a long microsatellite in the transactivating domain of the AR gene.

Women`s hearts need special treatment.

- Coronary heart disease (CHD) is the leading cause of death for both men and women in the Western world. Some studies show that the observed decline in cardiovascular mortality is not as pronounced among women as among men. There is a growing awareness that most earlier studies both on primary and secondary risk factors, diagnosis, prognosis, and rehabilitation have focused mainly on men. Thus, there is a need to develop knowledge about women with CHD and to address gender issues in treatment and rehabilitation strategies. Negative affect and emotions increase risk and may interfere with effective cardiac rehabilitation. Therefore, methods for coping with emotional stress need to be included in treatment regimens after a coronary event. The feasibility of a stress management program for women with CHD was assessed in a pilot study. The program consisted of twenty 2-hr group sessions during 1 year, with 5 to 9 participants per group. The pilot study showed that this treatment program had a low dropout rate and resulted in improvement in quality of life and reduction in stress and symptoms. Further work to optimize psychosocial interventions for women with CHD is needed.

Higher risk of colic in infants of nonmanual employee mothers with a demanding work situation in pregnancy.

- In this population-based study, we assessed the relation between socioeconomic and psychosocial conditions in 1,094 pregnant women and subsequent infantile colic by means of self-administered questionnaires measuring exposures in the 17th pregnancy week and telephone interviews at infant age 5 weeks. There was a higher risk of colic in infants born to younger mothers, mothers with low instrumental support in pregnancy, and mothers with nonmanual occupations. Having an "active" job situation, that is, high demands and high decision latitude at work, acted synergistically with a nonmanual occupation, yielding even higher odds ratios for colic as did concomitant low instrumental support and nonmanual occupation. An expected synergy between low social participation and nonmanual occupation could not be demonstrated. Findings from gender-related research may partly explain some of these results.
