    Objective: In the process of growing, adolescents experience stress either good or bad depending on how they cope. School training further adds to this stressful situation. It is noteworthy that persistent over stress will impair students’ academic achievement, personal and professional development. This preliminary study is meant to obtain initial data on the stress prevalence, stressors, and coping strategies among secondary school children in Malaysia. Data gained from this preliminary study provides valuable data for subsequence research in the future. Methods: This is a cross-sectional study involving 100 secondary school students from a Malaysian government secondary school. The validated Malay version 12-item General Health Questionnaire (GHQ-12), Soalselidik Stressor Sekolah Menengah (SSSM) and Malay version of Brief COPE were used to identify stress level, stressors, and coping strategies. Results: A number of 90 (90%) students participated in this study. The prevalence of stress among secondary school students was 26.1%. It was found that the main stressors were related to academic. The top five coping strategies were religion, positive reinterpretation, active coping, planning, and use of instrumental support. Conclusion: The prevalence of stress among secondary school students in a Malaysian
    stressor among the students. The most frequent coping strategies being used by the students were positive coping strategies.

    Objective: The objective of this study was to assess the relationship between stress score and body mass index (BMI) of students of Science in Kuala Lumpur. Methods: A cross-sectional study was carried out among 126 students. Data about stress score were collected using a questionnaire, the Student-Life Stress Inventory (SLSI) Data about BMI were calculated from height and weight of the respondents. Results: A total of 117 (92.85%) out of 126 students had responded. The mean difference of stress score among first, second and third year students were 87.6 ± 17.0, 83.4 ± 16.9 and 86.7 ± 15.4 respectively. The mean difference of stress scores between the Bumiputra and non-Bumiputra students were 87.9 ± 16.5 and 83.2 ± 15.9 .The mean of body mass Index(BMI) between first, second and third year students were 21.0 ± 3.5, 20.3 ± 2.7 and 21.8 ± 4.3 respectively. Conclusions: This study showed that the stress level is higher in first year, female and bumiputra student. There was no significant relationship between stress score and BMI.

    This study aims to assess the factor structure and reliability of the General Health Questionnaire (GHQ-12). Additionally, the study also attempts to evaluate the psychological well-being among university students using the GHQ-12 scale and thereby determine a relationship between select demographic variables and well-being. Methods: An exploratory cross-sectional survey was conducted among undergraduate students of a public university in Sarawak, Malaysia. A self administered questionnaire consisting of the demographic aspects and the GHQ 12 scale were utilized to assess the well-being of students, who were selected by convenience sampling technique. Results: Factorability of the GHQ-12 was examined and a three-factor model explaining 55% total variance was found to be the best fit. Internal consistency of the scale was 0.78, which is within the acceptable range. The results also suggest that considerable proportion (57%) of students had psychological distress. Participants who were susceptible to psychological distress in the present study were identified as students from low income families, with poor social support, in a relationship with partner as well as the student with Hindu’s religion and male students. By multiple regression analysis, variables that significantly predicted psychological distress were gender; income; area of residence; relationship with parents; negative life events; smoking; drinking and event with the overall model fit were 34%. Conclusion: Based on these findings, it may be foreseen that if prompt intervention is not provided to students in distress, they may be susceptible to depression, anxiety and stress. The findings have implications for teachers and counsellors, who are in a position to influence a wide range of students and provide support to improve the psychological well-being of students.

    Recently, our research team has reported that Tualang honey was able to improve immediate memory in postmenopausal women comparable with that of estrogen progestin therapy. Therefore the aim of the present study was to examine the effects of Tualang honey supplement on hippocampal morphology and memory performance in ovariectomized (OVX) rats exposed to social instability stress. Female Sprague-Dawley rats were divided into six groups: (i) sham-operated controls, (ii) stressed sham-operated controls, (iii) OVX rats, (iv) stressed OVX rats, (v) stressed OVX rats treated with 17β-estradiol (E2), and (vi) stressed OVX rats treated with Tualang honey. These rats were subjected to social instability stress procedure followed by novel object recognition (NOR) test. Right brain hemispheres were subjected to Nissl staining. The number and arrangement of pyramidal neurons in regions of CA1, CA2, CA3 and the dentate gyrus (DG) were recorded. Two-way ANOVA analyses showed significant interactions between stress and OVX in both STM and LTM test as well as number of Nissl-positive cells in all hippocampal regions. Both E2 and Tualang honey treatments improved both short-term and long-term memory and enhanced the neuronal proliferation of hippocampal CA2, CA3 and DG regions compared to that of untreated stressed OVX rats.

    A study was carried out to compare parenting stress between 116 mothers of very low birthweight (VLBW) children and 96 mothers of normal birthweight (NBW) children at 4 y of age, using the Parenting Stress Index (PSI). Multiple regression analysis was used to determine factors associated with child-domain stress (CDS) and parent-domain stress (PDS). There was a significantly higher proportion (39.7%) of mothers of VLBW children with high CDS scores >90th percentile than mothers of NBW children (20.8%). No significant differences were observed for PDS scores. Lower intelligence quotient (IQ) scores and adverse child behaviour, as evidenced by higher Child Behavior Checklist (CBCL) scores, were significantly associated with higher CDS scores (p < 0.001). Factors associated with higher PDS scores were higher CBCL scores (p < 0.001), mothers who were the primary caregivers (p < 0.001), male sex (p = 0.018) and lower level of maternal education (p = 0.048). These factors remained statistically significant even when physically and cognitively impaired children were excluded from the analysis.

    CONCLUSION: Specific child characteristics and the social environment appear to have a greater impact on parenting stress than the biological risk of VLBW birth per se.

    Pursuing undergraduate medical training can be very stressful and academically challenging experience. A 5-week mindfulness-based stress management (MBSM/Mindful-Gym) program was developed to help medical students cope with stress. The aim of this study was to evaluate the effectiveness of the intervention in reducing stress among students in a medical school in Malaysia. Seventy-five medical students participated in the program. They were stratified according to years of studies and randomly allocated to intervention (N = 37) and control groups (N = 38). The following outcome variables were measured at pre- and post-intervention: mindfulness (with Mindful Awareness Attention Scale); perceived stress (with Perceived Stress Scale); mental distress (with General Health Questionnaire), and self-efficacy (with General Self-efficacy Scale). Hierarchical multiple regressions were used to analyse the effect of group (intervention vs. control) on changes in the outcome variables. There were significant improvements at one week post-intervention in all outcome variables: mindfulness (β = 0.19, ΔR2 = 0.04, p = .040, f (2) = 0.05), perceived stress (β = -0.26, ΔR2 = 0.07, p = .009, f (2) = 0.10); mental distress (β = -0.28, ΔR2 = 0.10, p = .003, f (2) = 0.15); and self-efficacy (β = 0.30, ΔR2 = 0.09, p < .001, f (2) = 0.21). Six months after the intervention, those who had joined the program reported higher self-efficacy compared to those in the control group (β = 0.24, ΔR2 = 0.06, p = .020, f (2) = 0.08); but there was no difference in other outcome measures. More than 90% of the participants found the program applicable in helping patients and all reported that they would recommend it to others. This study indicates that the program is potentially an effective stress management program for medical students in Malaysia.

    OBJECTIVES: The aim of this study was to identify the predictors of elderly's cognitive function based on biopsychosocial and cognitive reserve perspectives.

    METHOD: The study included 2322 community-dwelling elderly in Malaysia, randomly selected through a multi-stage proportional cluster random sampling from Peninsular Malaysia. The elderly were surveyed on socio-demographic information, biomarkers, psychosocial status, disability, and cognitive function. A biopsychosocial model of cognitive function was developed to test variables' predictive power on cognitive function. Statistical analyses were performed using SPSS (version 15.0) in conjunction with Analysis of Moment Structures Graphics (AMOS 7.0).

    RESULTS: The estimated theoretical model fitted the data well. Psychosocial stress and metabolic syndrome (MetS) negatively predicted cognitive function and psychosocial stress appeared as a main predictor. Socio-demographic characteristics, except gender, also had significant effects on cognitive function. However, disability failed to predict cognitive function.

    CONCLUSION: Several factors together may predict cognitive function in the Malaysian elderly population, and the variance accounted for it is large enough to be considered substantial. Key factor associated with the elderly's cognitive function seems to be psychosocial well-being. Thus, psychosocial well-being should be included in the elderly assessment, apart from medical conditions, both in clinical and community setting.

    Purpose: The aim of this study was to develop a substantive theory that explains parenting stress among mothers of deaf or hard-of-hearing (D/HH) children.

    Method: Fifteen hearing mothers of children with severe-to-profound sensorineural hearing loss were interviewed. Interviews were transcribed verbatim, and a grounded theory approach was used to inductively analyze parental stress in mothers of D/HH children. Theory generation was achieved through triangulation of data sources and systematic organization of data into codes. The coding process identified salient themes that were constantly cross-checked and compared across data to further develop categories, properties, and tentative hypotheses.

    Results: In general, two main themes emerged from the interviews: the contextual stressors and stress-reducing resources. The contextual stressors were labeled as distress over audiology-related needs, pressure to acquire new knowledge and skills, apprehension about the child's future, and demoralizing negative social attitudes. The stress-reducing resources that moderated parenting stress were identified to be the child's progress, mother's characteristics, professional support, and social support. The interaction between the identified stressors and adjustment process uncovered a central theme termed maternal coherence.

    Conclusion: The substantive theory suggests that mothers of D/HH children can effectively manage parenting stress and increase well-being by capitalizing on relevant stress-reducing resources to achieve maternal coherence.

    We report here on a longitudinal study of stress and women's reproduction in a small Kaqchikel Mayan community in rural Guatemala. Current understanding of the effects of stress on the reproductive axis in women is mostly derived from clinical studies of individual stressors. Little is known, however, about the cumulative effects of "real life" stress. Cortisol increases in response to a broad variety of individual stressors (Tilbrook et al., 2002). In this article, we evaluate the association between daily fluctuations in women's urinary cortisol and reproductive hormones: estrone conjugates (E(1)C), pregnandiol glucuronide (PdG), luteinizing hormone (LH), and follicle stimulating hormone (FSH). To assess the association between daily changes in cortisol levels and changes in the profiles of the reproductive hormones, we used a random coefficients model based on polynomial regression. The sample includes 92 menstrual cycles provided by 24 participants over a year-long prospective study. Increases in urinary cortisol levels were associated with significant increases in gonadotrophin and progestin levels during the follicular phase. Also, in a time window between days 4 and 10 after ovulation, increased cortisol levels were associated with significantly lower progestin levels. These results are significant because untimely increases in gonadotrophins and low midluteal progesterone levels have previously been reported to impinge on the ovulatory and luteinization processes and to reduce the chances of successful implantation (Ferin, 1999; Baird et al., 1999). Future research should consider the possibility that stress may affect fecundability and implantation without necessarily causing amenorrhoea or oligomenorrhoea.

    Previous studies showed that exposure to stress or nicotine induced reproductive impairment in male rats. Here, we assessed the effect of an antioxidant (vitamin E) on nicotine-, stress- and nicotine + stress-induced reproductive impairment in male rats. Forty-eight male albino Wistar rats were divided into eight groups as follows; control, stress (generator noise 90-120 dB, 8 hr/day), nicotine (1.5 mg kg-1 day-1 ), nicotine + stress, vitamin E (100 mg kg-1 day-1 ), stress + vitamin E, nicotine + vitamin E and stress + nicotine + vitamin E. Sperm count, viability, motility and rapid progressive forward movement decreased significantly (p stress, nicotine and nicotine + stress groups, compared with control. Serum testosterone and follicle-stimulating hormone decreased significantly (p stress, nicotine and nicotine + stress groups, compared with control. Serum luteinising hormone decreased (p stress and nicotine + stress groups, compared with the control. Histology of the testes showed loss of germ cells in numerous seminiferous tubules, and epididymal histology showed decreased sperm density in stress, nicotine and nicotine + stress groups compared with the control. These negative changes were more severe in the nicotine + stress group. Vitamin E ameliorated the negative changes in the above parameters. This may be attributable to its antioxidant property.

    Background: Feelings of isolation, insecurity, and instability triggered by COVID-19 could have a long-term impact on the mental health status of individuals.

    Objectives: The aim of this study was to examine the prevalence of mental health symptoms (anxiety, depression, and stress) in Bangladesh and the factors associated with these symptoms during the COVID-19 pandemic.

    Methods: From 1 to 30 April 2020, we used a validated self-administered questionnaire to conduct a cross-sectional study on 10,609 participants through an online survey platform. We assessed mental health status using the Depression, Anxiety, and Stress Scale (DASS-21). The total depression, anxiety, and stress subscale scores were divided into normal, mild, moderate, severe, and multinomial logistic regression was used to examine associated factors.

    Findings: The prevalence of depressive symptoms was 15%, 34%, and 15% for mild, moderate, and severe depressive symptoms, respectively. The prevalence of anxiety symptoms was 59% for severe anxiety symptoms, 14% for moderate anxiety symptoms, and 14% for mild anxiety symptoms, while the prevalence for stress levels were 16% for severe stress level, 22% for moderate stress level, and 13% for mild stress level. Multivariate analyses revealed that the most consistent factors associated with mild, moderate, and severe of the three mental health subscales (depression, anxiety, and stress) were respondents who lived in Dhaka and Rangpur division, females, those who self-quarantined in the previous seven days before the survey, and those respondents who experienced chills, breathing difficulty, dizziness, and sore throat.

    Conclusion: Our results showed that about 64%, 87%, and 61% of the respondents in Bangladesh reported high levels of depression, anxiety, and stress, respectively. There is a need for mental health support targeting women and those who self-quarantined or lived in Dhaka and Rangpur during the pandemic.

    BACKGROUND: The population of end-stage renal failure (ESRF) receiving dialysis treatment is increasing worldwide. For most patients with ESRF, dialysis can extend their life. However, treatment can be demanding and time-consuming. Despite dialysis treatment, many patients continue to experience various sufferings.

    METHODS: A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering of ESRF patients on maintenance dialysis in Malaysia. The results were thematically analyzed.

    RESULTS: Nineteen ESRF patients were interviewed. The themes and subthemes were: (I) physical suffering-physical symptoms and functional limitations, (II) psychological suffering-the emotions and thoughts of suffering, (III) social suffering-healthcare-related suffering and burdening of others and (IV) spiritual suffering-the queries of suffering.

    CONCLUSIONS: These findings may help healthcare professionals to fill in the gaps in the delivery of best renal palliative care.

    OBJECTIVE: To assess the degree of psychological impact among surgical providers during the COVID-19 pandemic.

    SUMMARY OF BACKGROUND DATA: The COVID-19 pandemic has extensively impacted global healthcare systems. We hypothesized that the degree of psychological impact would be higher for surgical providers deployed for COVID-19 work, certain surgical specialties, and for those who knew of someone diagnosed with, or who died, of COVID-19.

    METHODS: We conducted a global web-based survey to investigate the psychological impact of COVID-19. The primary outcomes were the depression anxiety stress scale-21 and Impact of Event Scale-Revised scores.

    RESULTS: A total of 4283 participants from 101 countries responded. 32.8%, 30.8%, 25.9%, and 24.0% screened positive for depression, anxiety, stress, and PTSD respectively. Respondents who knew someone who died of COVID-19 were more likely to screen positive for depression, anxiety, stress, and PTSD (OR 1.3, 1.6, 1.4, 1.7 respectively, all P < 0.05). Respondents who knew of someone diagnosed with COVID-19 were more likely to screen positive for depression, stress, and PTSD (OR 1.2, 1.2, and 1.3 respectively, all P < 0.05). Surgical specialties that operated in the head and neck region had higher psychological distress among its surgeons. Deployment for COVID- 19-related work was not associated with increased psychological distress.

    CONCLUSIONS: The COVID-19 pandemic may have a mental health legacy outlasting its course. The long-term impact of this ongoing traumatic event underscores the importance of longitudinal mental health care for healthcare personnel, with particular attention to those who know of someone diagnosed with, or who died of COVID-19.

    Consequent to rapidly declining mortality and birth rates, developing countries, including Malaysia, can expect a rapid increase in the population aged 60 years and above. The health of the elderly is intimately tied up with both biophysical as well as psychosocial factors which include status loss, loneliness, fear of illness and death, poverty, harmful life-styles and deterioration of the quality of life. The effects of these psychosocial factors can manifest as sleep difficulties, worry and anxiety, depression, loss of interest, and a feeling of tiredness. In extreme cases, there may be auditory or visual hallucinations or paranoia. In the present paper, which is based upon a WHO sponsored study of 1001 elderly Malaysians, it is noted that 36% of the elderly have sleep difficulties, 47% "feel tired", 31% have a "loss of interest" and 22% are "worried tense". However 71% of the elderly are able to correctly perform at least 12 of 15 cognitive tests. 20% of elderly men smoke 15 or more cigarettes a day while 44% smoke at least one cigarette a day. 40% of elderly men indicate that their families complain about the amount of alcohol they drink. Undoubtedly primary health care programmes need to be re-oriented to the problems and needs of the elderly in countries such as Malaysia.

    A hospital study was carried out to compare parenting stress among 87 Malaysian mothers of children with cerebral palsy and a control group (comprising 87 mothers of children without disability who attended the walk-in paediatric clinic), using the Parenting Stress Index (PSI) questionnaire. Multiple regression analysis was used to determine socio-demographic and medical factors associated with child-domain stress (CDS) and parent-domain stress (PDS). Mothers of children with cerebral palsy scored significantly higher than control subjects on all sub-scales of CDS and PDS (p < 0.01), except for the sub-scale of 'role restriction'. The presence of cerebral palsy (p < 0.001) and activities of daily living (ADL) scores (p < 0.001) were significantly associated with CDS. Factors predictive of PDS were ADL scores (p < 0.001), number of hospitalizations over the past year (p = 0.024), level of maternal education (p = 0.018) and Chinese mothers (p < 0.001). Although this study demonstrated that Malaysian mothers of children with cerebral palsy experienced higher levels of stress than controls, the impact of cerebral palsy per se on parenting stress was modified by other factors such as increased care-giving demands, low maternal education and ethnic background. Habilitation should be directed at easing the burden of daily care, minimizing hospital re-admissions and targeting appropriate psychosocial support at specific subgroups to change parental perception and expectations.

    Previous works on the effects of salivary alpha amylase in respond to various stressors report encouraging findings on it being a good indicator of stress. Ellestad protocol is a clinical procedure to screen for coronary artery disease by introducing exercise induced physical stress. If a salivary based biomarker profile in accordance to a stress test protocol could be established, the critical stress state which disable rational decision making could be ascertained in a standardized procedure. This technique would serve to aid human resource management in times of critical events such as rescue, firefighting or even military, that would potentially prevent unnecessary sacrifice of human lives. In this pilot study with five healthy volunteers performing the Ellestad protocol treadmill, a measurement profile with physiologic and salivary based biomarker is obtained. It is found that the alpha amylase levels or the changes in it as workload changes from resting-walking-running at ease-exhaustive running, is relatively more significant in reflecting the stress state than heart rate and blood pressure. Moreover, it is strongly associated with mood state with correlation coefficient of 0.8 and significance of 0.01.

    The mechanism linking biopsychosocial factors to disordered eating among university students is not well understood especially among Malaysians. This study aimed to examine the mediating role of psychological distress in the relationships between biopsychosocial factors and disordered eating among Malaysian university students. A self-administered questionnaire measured self-esteem, body image, social pressures to be thin, weight-related teasing, psychological distress, and disordered eating in 584 university students (59.4% females and 40.6% males). Body weight and height were measured. Structural equation modeling analysis revealed that the partial mediation model provided good fit to the data. Specifically, the relationships between self-esteem and weight-related teasing with disordered eating were mediated by psychological distress. In contrast, only direct relationships between body weight status, body image, and social pressures to be thin with disordered eating were found and were not mediated by psychological distress. Furthermore, multigroup analyses indicated that the model was equivalent for both genders but not for ethnic groups. There was a negative relationship between body weight status and psychological distress for Chinese students, whereas this was not the case among Malay students. Intervention and prevention programs on psychological distress may be beneficial in reducing disordered eating among Malaysian university students.
