Measuring psychosocial stress with heart rate variability-based methods in different health and age groups
2022
Abstract Objective. Autonomic nervous system function and thereby bodily stress and recovery reactions may be assessed by wearable devices measuring heart rate (HR) and its variability (HRV). So far, the validity of HRV-based stress assessments has been mainly studied in healthy populations. In this study, we determined how psychosocial stress affects physiological and psychological stress responses in both young (18–30 years) and middle-aged (45–64 years) healthy individuals as well as in patients with arterial hypertension and/or either prior evidence of prediabetes or type 2 diabetes. We also studied how an HRV-based stress index (Relax-Stress Intensity, RSI) relates to perceived stress …
Hormonal differences in intimate partner violence perpetrators when they cope with acute stress: A pilot study
2021
Background: Only a few studies have paid attention to the ability of perpetrators of intimate partner violence (IPVAW) against women to cope with acute stress, including hormonal pa-rameters. In fact, previous studies assessed how salivary testosterone (Tsal) and cortisol (Csal) changed after coping with an acute emotional stressor (directly related to IPVAW), and they con-cluded that an imbalance between the two hormones might be characteristic of these men. Never-theless, they neglected to examine the role of other hormones, such as salivary oxytocin (OXsal), which also seemed to play an important role in behavioral regulation, and whether this response could be generalized to other types…
Salivary Testosterone and Cortisol as Biomarkers for the Diagnosis of Sarcopenia and Sarcopenic Obesity in Community-Dwelling Older Adults
2021
Nowadays, the appearance of sarcopenia (S) or sarcopenic obesity (SO) is related to aging. According to the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP), the feasibility of using salivary cortisol and testosterone levels was analyzed as diagnostic biomarkers of S or SO. One hundred and ninety non-institutionalized people aged &ge
Sport for job. Differences in cortisol levels in a water polo team at different times of workout
2018
Agonistic sport represents a physically stressful situation associated with the release of catecholamine and cortisol that in turn influence the immune system. This study aimed to investigate the influence, in a team of water polo players, of the emotional processes characterizing the phase of waiting for the race on endocrine changes at the end of an official match. Thirteen professional water polo players participated in this study. Each player provided two saliva samples before and after three different time phases: (1) rest time, (2) workout and (3) competition. The results of the present study showed a significant increase in salivary cortisol levels before and after the competition an…

A preliminary study to assess the impact of maternal age on stress-related variables in healthy nulliparous women
2017
Purpose: Childbearing age has progressively increased in industrialized countries. The impact of this delay on motherhood, however, requires further research. Methods: The study sample included a prospective cohort of healthy nulliparous pregnant women aged between 18 and 40 years (n = 148) assessed at 38 weeks gestation (Time#1, T1), 48 h after birth (Time#2, T2), and 3 months after birth (Time#3, T3). The effect of age on psychological, biological, and social variables was evaluated. Maternal psychological symptoms in terms of depression and anxiety were assessed at T1-T3; and parenting stress at T3. Stress biomarkers (cortisol, alpha-amylase) were determined in mothers at T1-T3. Question…
The Relationship between COVID-19 and Hypothalamic-Pituitary-Adrenal Axis: A Large Spectrum from Glucocorticoid Insufficiency to Excess-The CAPISCO I…
2022
Coronavirus disease 2019 (COVID-19) is a highly heterogeneous disease regarding severity, vulnerability to infection due to comorbidities, and treatment approaches. The hypothalamic–pituitary–adrenal (HPA) axis has been identified as one of the most critical endocrine targets of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that might significantly impact outcomes after infection. Herein we review the rationale for glucocorticoid use in the setting of COVID-19 and emphasize the need to have a low index of suspicion for glucocorticoid-induced adrenal insufficiency, adjusting for the glucocorticoid formulation used, dose, treatment duration, and underlying health problems. We a…
The Role of Personal Biological Resource in the Job Demands-Control-Support Model: Evidence From Stress Reactivity.
2021
Job resources can buffer the deleterious effect of adverse work environments. Extant studies on the interaction pattern between job resources and adverse environments were confined to the diathesis stress model. This traditional perspective has received the challenge from the differential susceptibility model and the vantage sensitivity model. Additionally, stress reactivity may be one of the important job resources at the personal biological level, but its moderating role was short of empirical research. This study aimed to examine how stress reactivity interacts with work environments in predicting job burnouts among 341 Chinese hospital female nurses. This study selected job control and …
Chronic social stress lessens the metabolic effects induced by a high-fat diet
2021
Stress has a major impact on the modulation of metabolism, as previously evidenced by hyperglycemia following chronic social defeat (CSD) stress in mice. Although CSD-triggered metabolic dysregulation might predispose to pre-diabetic conditions, insulin sensitivity remained intact, and obesity did not develop, when animals were fed with a standard diet (SD). Here, we investigated whether a nutritional challenge, a high-fat diet (HFD), aggravates the metabolic phenotype and whether there are particularly sensitive time windows for the negative consequences of HFD exposure. Chronically stressed male mice and controls (CTRL) were kept under (i) SD-conditions, (ii) with HFD commencing post-CSD,…
Influence of a Cognitive Behavioural Training Program on Health: A Study among Primary Teachers // Influencia de un programa de entrenamiento cogniti…
2013
This longitudinal study was carried out to assess the efficacy of a cognitive behavioural training program that was designed to modify the cognitive and emotional processes related to work stress in a sample of teachers. The training group consisted of 21 teachers, and the non training group comprised of 16 teachers. The training program was divided into four on-site sessions, and the difference between time 1 and time 2 was 4 months. The training program significantly reduced psychosomatic disorders levels in the training group from Time 1 to Time 2, and it significantly increased cortisol levels from time 1 to time 2.
