The effects of the menstrual cycle on social decision making

The cyclic change in hormonal profiles between the two main phases of the menstrual cycle mediate shifts in mate preference. Males who advertise social dominance are preferred over other men by females in the follicular phase of the cycle. The present study explored assignment of high or low status resources to dominant looking men by females in either phase of the menstrual cycle. Thirteen females who reported that they were free from any kind of hormonal intervention and experienced a 28 day cycle, were invited to participate in a mock job negotiation scenario. Participants were asked to assign either a minimum, low, high or maximum social status job package to a series of male 'employees' that were previously rated to look either dominant or non-dominant. The results showed that during the follicular phase of the cycle participants assigned dominant looking men more high status job resources than the non-dominant looking men. However, during the luteal phase the participants assigned low status resources to the non-dominant looking men. Females are not merely passive observers of male status cues but actively manipulate the environment to assign status. © 2006 Elsevier B.V. All rights reserved.

Sense of coherence and diabetes:a prospective occupational cohort

Background: Sense of coherence (SOC) is an individual characteristic related to a positive life orientation leading to effective coping. A weak SOC has been associated with indicators of general morbidity and mortality. However, the relationship between SOC and diabetes has not been studied in prospective design. The present study prospectively examined the relationship between a weak SOC and the incidence of diabetes. Methods: The relationship between a weak SOC and the incidence of diabetes was investigated among 5827 Finnish male employees aged 18–65 at baseline (1986). SOC was measured by questionnaire survey at baseline. Data on prescription diabetes drugs from 1987 to 2004 were obtained from the Drug Imbursement Register held by the Social Insurance Institution. Results: During the follow-up, 313 cases of diabetes were recorded. A weak SOC was associated with a 46% higher risk of diabetes in participants who had been =<50 years of age on entry into the study. This association was independent of age, education, marital status, psychological distress, self-rated health, smoking status, binge drinking and physical activity. No similar association was observed in older employees. Conclusion: The results suggest that besides focusing on well-known risk factors for diabetes, strengthening SOC in employees of =<50 years of age can also play a role in attempts to tackle increasing rates of diabetes.
