background: nowadays job stress is one of the most important health problems that health and safety professionals are facing with. much of previous studies have focused on interventions such as stress management and, they have ignored the role of psychosocial factors in occurrence of job stress. this study investigated the mediator role of supervisor support on the association between work stre...

Although postnatal psychologic distress has been widely studied for many years, particularly with a focus on postpartum depression, symptoms of maternal depression, stress, and anxiety are not more common or severe after childbirth than during pregnancy. This paper reviews the newer body of research aimed at identifying the effects of women's antenatal psychologic distress on fetal behavior and...

In a recent Grand Rounds in Environmental Medicine article, Wright and Steinbach (1) highlighted the influence of psychosocial stress on asthmatic attacks. The reported case histories support basic neuroimmunologic studies, which document modulation of immune reactivities by psychologic stress, and the need to consider psychologic stress along with environmental chemical and physical stresses, ...

We have read with interest the work by Lesgards et al. (1) on the effect of different lifestyle factors on their test system, which measures the resistance of red blood cells to an oxidative challenge. Their study showed that psychologic stress is a major factor influencing antioxidant status. This finding encouraged us to share our experiences of a earlier study that resulted in similar conclu...

Extract: The perspective that cancer may be causally linked to stress has a long history. In 200 AD, Galen proposed that melancholic women were more susceptible to cancer than women who were sanguine. Rigorous examinations of related observations have lagged over the ensuing centuries. More recently, epidemiologic studies have shown that psychologic and social characteristics (e.g., chronic str...

Four experiments examined the effects of stressor predictability on a variety of stress responses, such as stomach ulceration, plasma corticosterone concentration and body weight changes. Rats that received electric shocks unpredictably showed greater somatic stress reactions and more stress-induced pathology than animals that received the same shocks but could predict their occurrence by a sig...

College women who are prehypertensive and matched controls were exposed to emotion-provoking situations, psychologic tests, and psychiatric interviews. Patterns of response differentiating the groups were observed. The prehypertensives were less well controlled, more impulsive, more egocentric, and generally less adaptable in the stressful situations. In the psychiatric interviews, behavior sim...

Public speaking is a widely requested professional skill, and at the same time an activity that causes one of the most common adult phobias (Miller and Stone, 2009). It is also known that the study of stress under laboratory conditions, as it is most commonly done, may provide only limited ecological validity (Wilhelm and Grossman, 2010). Previously, we introduced an inter-disciplinary methodol...

Chronic psychologic stress increases corticosterone levels, which decreases bone density. Active mastication or chewing attenuates stress-induced increases in corticosterone. We evaluated whether active mastication attenuates chronic stress-induced bone loss in mice. Male C57BL/6 (B6) mice were randomly divided into control, stress, and stress/chewing groups. Stress was induced by placing mice ...
