Occupational Stress versus Cortisol Associated with Psychological Variables and Gender Differences among Women and Men in Nursing

Abstract

The present research focused on a sample of Spanish male and female nurses to determine whether psychological variables are related to occupational stress and cortisol. Spanish male (n = 98) and female (n = 98) nurses, matched in diverse sociodemographic variables, completed measures of occupational stress, cortisol 8 am (8 h), and cortisol 8 pm (20 h), and psychological variables. Multivariable regression analyses revealed different patterns of association among the variables when analyzing subjective and (occupational stress) objective indicators (cortisol at 8 h and cortisol at 20 h). In male nurses, higher stress is related to worse self-perceived health, worse mental health, less cortisol measured at 8 h, and more morningness. For the female nurses, higher stress is related to being younger, worse self-perceived health, and less job satisfaction. The only similarities found in the target variables and the measures of stress studied in the groups of males and females are worse self-perceived health and worse mental health associated with more occupational stress.
