Hair cortisol concentration (HCC) is a valuable biomarker for evaluating chronic stress in preschoolers. However, few studies have explored early life HCC and its associated factors. This prospective cohort study analysed the HCC in children aged 6-48 months and its associations with parental HCC as well as positive and negative parental mental health outcomes. We used data from the ongoing Longitudinal Examination Across Prenatal and Postpartum Health in Taiwan (LEAPP-HIT) project, conducted in Taipei between 2020 and 2024. Hair samples were collected from both parents and children in 177 families (91 samples obtained during pregnancy and 86 during the postpartum period). The parents also completed self-reported questionnaires. Multiple linear regression was conducted to analyse the data. We observed a significant positive correlation between parents\' and preschoolers\' HCC. Furthermore, maternal depression (adjusted beta coefficient [aβ] = 0.09, 95% confidence interval [CI] = 0.02, 0.16) and perceived stress (aβ = 0.15, 95% CI = 0.02, 0.26) were positively associated with preschoolers\' HCC. By contrast, higher maternal eudaimonia was associated with lower HCC in preschoolers (aβ = -0.11, 95% CI = -0.20, -0.01). For parents, maternal depression, anxiety, and perceived stress were independently associated with an increased HCC during the postnatal period, whereas maternal eudaimonia was negatively associated with HCC. Our results indicate that both mothers and fathers affect children\'s responses to stress. Assessment of cortisol stress hormone concentrations through hair samples can be a key means of detecting preschoolers\' stress levels and enabling early intervention.

Life satisfaction refers to an individual\' s cognitive evaluation of the overall quality of their life considering the various aspects therein. Although the existing research has demonstrated the between-person relationship between negative life events and life satisfaction based on retrospective measures, less is known about this relationship at the within-person level. A daily diary method could examine this within-person relationship and decrease systematic recall biases. Therefore, this study investigated the link between daily negative life events and daily life satisfaction, as well as the mediating role of perceived stress and the moderating role of trait rumination in 146 young adults (Mage = 20.75, SD = 1.35) using a 14-day daily diary design. Multilevel regression analysis showed that daily negative life events had negative predictive effects on daily life satisfaction. In addition, the multilevel 1-1-1 mediation analysis indicated that daily perceived stress mediated the association between daily negative life events and daily life satisfaction. More importantly, the mediating effect of perceived stress was moderated by trait rumination, with the within-person mediating effect being stronger for individuals with higher than those with lower trait rumination tendencies. These findings contribute to the understanding of the underlying pathways in the relationship between daily negative life events and daily life satisfaction and provide a new perspective for improving individuals\' life satisfaction.

UNASSIGNED: Psychosomatic complaints are common in youth and are often assumed to indicate stress. Although several studies have confirmed that a cross-sectional association exists, few have empirically investigated whether or not perceived stress influences psychosomatic complaints. The objective of the present study was to build upon previous research by exploring whether changes in perceived stress over time are associated with corresponding changes in psychosomatic complaints. This analytical approach takes unmeasured time-invariant confounding into account, thereby offering more robust evidence for a causal association between the variables under study.
UNASSIGNED: Data was derived from the Swedish national cohort study Futura01, with information from 2,708 participants aged 17-18 in 2019 and 20-21 in 2022. Perceived stress was measured by Cohen\'s Perceived Stress Scale. Psychosomatic complaints were measured by questions on the frequency of stomach aches, headaches and difficulties falling asleep, which were added to an index. Information on gender, parental education, and parental country of birth was derived from registries. Linear regression analyses were conducted and the first difference (FD) approach was used.
UNASSIGNED: Perceived stress and psychosomatic complaints exhibited cross-sectional associations at both time points. The FD analyses showed that increases in perceived stress were associated with increases in psychosomatic complaints, and this was the case irrespective of sociodemographic characteristics.
UNASSIGNED: This study provides further empirical support for the assumption that psychosomatic complaints can be partially attributed to stress. Societal efforts aimed at reducing stressors and strengthening coping resources and strategies among young people may help mitigate perceived stress and, consequently, the likelihood of developing psychosomatic complaints.

BACKGROUND: The family environment has a significant influence on the personality development of young people and their assessment of life satisfaction. Perceived stress is related to life satisfaction, but this relationship is also influenced by the family context. The present study analysed the impact of perceived stress on life satisfaction and the mediating role of family climate in university students.
METHODS: A sample of 920 university students was recruited for this study. The instruments used included the Perceived Stress Scale, the Satisfaction with Life Scale, and the Family Social Climate Scale, and socioeducational information was collected.
RESULTS: The results indicate that perceived stress had a significant and positive effect on both conflictive and violent family climates, while life satisfaction was negatively impacted by these negative family climates. Additionally, supportive and cohesive family climates, along with difficulty expressing feelings and opinions, were found to have significant positive effects on life satisfaction.
CONCLUSIONS: These findings highlight the importance of the family system in shaping individual conditions and how it can regulate the relationship between stress and life satisfaction.

BACKGROUND: Meningiomas are the most common type of primary brain tumor, originating from the meninges - the protective membranes that surround the brain and spinal cord. Several well-studied risk factors for meningiomas include gender, age, radiation exposure, genetic factors, and hormonal factors. Moreover, the influence of a person\'s psycho-emotional stateon their overall health and mental well-being, specifically stress, iscurrently a significant and relevant topic of discussion.
OBJECTIVE: This case-control study aimed to study the association between perceived stress, chronic stress, and meningioma in adult patients.
RESULTS: The study included cases, which comprised adult patients with histologically confirmed meningioma, and controls, consisting of adult patients with no history of brain cancer. Data collection involved the use of three types of questionnaires. The first questionnaire focused on patients\' personal information, geographic factors, and lifestyle habits. Two additional questionnaires \"The Perceived Stress Scale\" and \"The Chronic Stress Scale\" were employed to assess perceived stress and chronic stress. The questioning was conducted by a neurologist. Microsoft Excel and Stata 14 were used for the data analysis. Overall, 148 questionnaires were completed and included in the analyses. The average age of participants was 45.60 ± 13.90 years. Females outnumbered males in both groups. Patients with meningioma diagnosis had a higher level of perceived high stress compared to those without meningioma (p = .045). Respondents without a diagnosis of meningioma have reported having more chronic stress in general and ambient problems (p = .004), financial issues (p = .006), work (p < .001), non-employment (p = .008), love and marriage (p < .001), isolation (p < .001), and residence (p < .001). Patients with meningioma, however, had less chronic stress compared to meningioma-free patients.
CONCLUSIONS: This study revealed no discernible connection between stress and meningioma within our study sample. Further research with matched case-control methodology with a larger sample size is warranted to thoroughly evaluate the potential role of stress in patients with meningioma.

Cardiovascular disease (CVD) continues to be the leading cause of death in the United States, with African Americans experiencing higher age-adjusted mortality compared to Whites. African American women in particular carry a high CVD burden due to more exposure to adverse personal and socioenvironmental challenges. Church-based interventions can improve health behaviors and health status of African Americans, yet few have addressed stress-related health. The purpose of this study was to determine the effectiveness of the 18-month Health for Hearts United intervention in relation to stress-related outcomes (perceived stress, allostatic load) of mid-life and older African American women (≥45 years of age; n = 152 overall sample, n = 65 clinical subsample). The results of the repeated measures analysis of variance (ANOVA) analyses showed overall significant decreases in perceived stress and allostatic load for both treatment and comparison groups over the measurement occasions (baseline and 18 months) with educational level remaining as a significant correlate over time. There was no significant interaction between treatment and time, yet there were trends in improvements for the treatment group compared to the comparison group. The findings demonstrate the potential of church-based interventions in reducing both self-reported stress and allostatic load in African American women, and highlight the need for further investigation of educational level and other possible factors influencing stress management in these settings.

OBJECTIVE: The traumatic experience of cancer, in addition to its negative impact on breast cancer patients, can also bring about positive change, i.e., post-traumatic growth (PTG). PTG can help boost patients\' confidence in their fight against the disease and improve their adherence to treatment, thereby facilitating their recovery. The study aimed to investigate the effect of perceived stress on the PTG of patients undergoing postoperative chemotherapy for breast cancer and to examine the roles of rumination and self-efficacy between two.
METHODS: The data was collected using a cross-sectional design. From December 2021 to October 2022, a total of 306 breast cancer patients who had undergone chemotherapy following surgery and met the inclusion and exclusion criteria were selected from three tertiary-level A hospitals in Henan Province, China. We conducted descriptive analysis, Pearson correlation analysis, and a regression analysis using PROCESS Macro Model 80 to explore the relationships among perceived stress, rumination, self-efficacy, and PTG.
RESULTS: Perceived stress of patients undergoing postoperative chemotherapy for breast cancer had a negative predictive effect on PTG (r = -0.340, P < 0.01); Rumination and self-efficacy played a partial mediating effect between perceived stress and PTG, accounting for 45.25% of the total effect.
CONCLUSIONS: Clinical nursing staff could promote PTG by strengthening psychological assessment and timely psychological intervention for patients with high perceived stress levels, encourage patients to adopt a positive way of thinking about illness and improve their self-efficacy level, so as to improve their PTG level.

BACKGROUND: Health care workers (HCWs) frequently face multiple stressors at work, particularly those working night shifts. HCWs who have experienced distress may find it difficult to adopt stress management approaches, even if they are aware of the effects of stress and coping processes. Therefore, an individualized intervention may be required to assist distressed HCWs in bridging the \"knowledge-practice\" gap in stress management and effectively alleviating stress symptoms.
OBJECTIVE: The main objective of this research was to compare the effects of a complex interactive multimodal intervention (CIMI) to self-guided stress management interventions on stress symptoms of distressed HCWs, as measured by physiological (heart rate variability), psychological (perceived stress, mental distress, and subjective happiness), and sleep disorder (fatigue and sleepiness) indicators.
METHODS: We conducted a nonrandomized, controlled study in 2 Chinese general hospitals. The participants in this study were 245 HCWs who fulfilled at least 1 of the 3 dimensions on the Depression, Anxiety, and Stress Scale. All eligible individuals were required to complete a questionnaire and wear a 24-hour Holter device to determine the physiological signs of stress as indexed by heart rate variability at both baseline and after the intervention. The CIMI group received a 12-week online intervention with 4 components-mobile stress management instruction, a web-based WeChat social network, personalized feedback, and a nurse coach, whereas the control group simply received a self-guided intervention.
RESULTS: After a 12-week intervention, the Perceived Stress Scale (PSS) scores reduced significantly in the CIMI group (mean difference [MD] -5.31, 95% CI -6.26 to -4.37; P<.001) compared to the baseline levels. The changes in PSS scores before and after the intervention exhibited a significant difference between the CIMI and control groups (d=-0.64; MD -4.03, 95% CI -5.91 to -2.14; P<.001), and the effect was medium. In terms of physiological measures, both the control group (MD -9.56, 95% CI -16.9 to -2.2; P=.01) and the CIMI group (MD -8.45, 95% CI -12.68 to -4.22; P<.001) demonstrated a significant decrease in the standard deviation of normal-to-normal intervals (SDNN) within the normal clinical range; however, there were no significant differences between the 2 groups (d=0.03; MD 1.11, 95% CI -7.38 to 9.59; P=.80).
CONCLUSIONS: The CIMI was an effective intervention for improving sleep disorders, as well as parts of the psychological stress measures in distressed HCWs. The findings provide objective evidence for developing a mobile stress management intervention that is adaptable and accessible to distressed HCWs, but its long-term effects should be investigated in future research.

OBJECTIVE: Diet plays a fundamental role in promoting resilience against stress-related disorders. We aimed to examine the overall and sex-specific association between food groups and perceived stress in adults.
METHODS: We analyzed the prospective data of 7,434 adults who completed both the 2011 and 2015 surveys of the China Health and Nutrition Survey (CHNS). The Diet Quality Questionnaire (DQQ) was used to code all the food items of 2011 dietary intake into 29 food groups, and perceived stress in 2015 was measured using a 14-item perceived stress scale (PSS-14). Univariate analysis and logistic regression models were used to examine the relationship between food groups and perceived stress.
RESULTS: People who perceived a higher level of stress (PSS-14 total score > 25) made up 41.5% and 45.1% of the male and female groups, respectively (χ2 = 9.605, p = 0.002). Individuals with increased intake of food groups such as legumes, other vegetables, other fruits, yogurt, poultry, fish & seafood, fluid milk, and fruit juice were less likely to experience a higher level of psychological stress (OR range: 0.544-0.892, p < 0.05). Additionally, we found sex-specific associations between food groups and perceived stress. The difference in the proportion of food groups, such as fluid milk and fish & seafood, between the two stress groups in men was statistically significant (p < 0.025). In the female group, the distribution of eight food groups, like legumes and nuts & seeds, between the two stress groups was statistically significant (p < 0.025).
CONCLUSIONS: This study indicated that food groups were differentially associated with perceived stress.

BACKGROUND: Abortion is a stressful event that can often affect the mental health of both parents. It seems that resilient people can adapt to stressful situations. The mental health of fathers plays an important role in improving the mental health of the family, but few studies have been conducted in this regard. Therefore, this study aimed to investigate depression, anxiety, perceived stress and resilience of fathers faced with their spouse\'s abortion.
METHODS: This longitudinal study was conducted on 125 spouses of women hospitalized in the post-partum department of Shiraz hospitals in 2023. Data collection tools included questionnaires of demographic and fertility characteristics, hospital depression and anxiety (HADS), Cohen\'s perceived stress, and Connor\'s resilience. The data were analyzed through Spss24 software using Friedman\'s tests and post hoc tests, Adjusted Bonferroni, Kruskal-Wallis and Mann-Whitney tests.
RESULTS: The mean age of the fathers was 35.02 ± 6.22. The scores of the father\'s anxiety, depression, and perceived stress from 24 h to 12 weeks after abortion were decreased significantly. However, their resilience score increased significantly. Also, there was a significant relationship between the fathers\' age, education, job, duration of marriage, type of abortion, number and history of abortion, unwanted pregnancy, number of children and economic status with the mean score of anxiety, depression, perceived stress, and resilience in fathers over time.
CONCLUSIONS: This research pointed out the effect of abortion on depression, anxiety, and perceived stress in fathers; also, resilience as a coping factor could affect these disorders and improve the fathers\' mental health. Therefore, screening and managing mental disorders in them are important to improve family health.
