Poor sleep quality and daytime somnolence is reported to be associated with cardiovascular events, road traffic accident, poor academic performance and psychological distress. Some studies documented that it is prevalent in most populations but its frequency among medical students has not been documented in Malaysia. This is a self-administered questionnaire survey of medical students from International Medical University, Malaysia. Daytime sleepiness of medical students was assessed using Epworth Sleepiness Scale (ESS). Student scoring ESS > 11 was regarded as having excessive daytime sleepiness. Psychological distress was measured using 12-item General Health Questionnaire (GHQ-12). A total of 799 medical students participated in this survey (response rate 69.5%). Daytime sleepiness occurred in 35.5%, psychological distress was present in 41.8% and 16.1% reported bad sleep quality. Daytime sleepiness was significantly more common among the clinical students, those with self-reported bad sleep quality and psychological distress; but unrelated to the number of hours sleep at night. We have documented high prevalence of daytime sleepiness, poor sleep quality and psychological distress. Higher frequency among clinical students and the significant relationship with psychological distress suggest possible link to the stressful clinical training.
Quercetin is a bioflavonoid abundant in onions, apples, tea and red wine and one of the most studied flavonoids. Dietary quercetin intake is suggested to be health promoting, but this assumption is mainly based on mechanistic studies performed in vitro. The objective of this study was to investigate the effect of quercetin on stress-induced changes in oxidative biomarkers in the hypothalamus of rats. Adult male Sprague Dawley rats were subjected to forced swimming stress for 45 min daily for 14 days. Effect of quercetin at three different doses (10, 20 and 30 mg/kg body weight) on serum corticosterone and oxidative biomarkers (lipid hydroperoxides, antioxidant enzymes and total antioxidants) was estimated. Swimming stress significantly increased the serum corticosterone and lipid hydroperoxide levels. A significant decrease in total antioxidant levels and super oxide dismutase, glutathione peroxidase and catalase levels was seen in the hypothalamus after stress and treatment with quercetin significantly increased these oxidative parameters and there was a significant decrease in lipid hydroperoxide levels. These data demonstrate that forced swimming stress produced a severe oxidative damage in the hypothalamus and treatment with quercetin markedly attenuated these stress-induced changes. Antioxidant action of quercetin may be beneficial for the prevention and treatment of stress-induced oxidative damage in the brain.
The teaching profession is an occupation at high risk for stress. This research attempted to determine the prevalence of stress and the associated factors contributing to stress among teachers in Malaysia. A cross-sectional study was conducted on 580 secondary school teachers in Kota Bharu District. The instrument used to carry out the study was adopted and modified from the Depression, Anxiety and Stress Scale (DASS 21) and Job Content Questionnaire (JCQ). The questionnaire consisted of two parts: Part I consisting non-job factors (socio-demographic characteristics) and Part II consisting of psychosocial factors contributing to stress. Simple and multiple linear regression analysis were carried out. The prevalence of stress was reported as 34.0%. Seventeen point four percent of teachers experienced mild stress. Age, duration of work and psychological job demands were significantly associated with stress level. This study indicates job-related factors did not contribute much to stress among secondary school teachers. Non-job-related factors should be further studied to determine methods for stress reduction in teachers in Malaysia.
Due to a dearth of research on depressive symptoms in Malaysia, particularly in Malay women, a community study was conducted to examine the prevalence and factors associated with current depressive symptoms in rural and urban Malay women with low socioeconomic status.
Increasing numbers of workers use computer for work. So, especially among office workers, there is a high risk of musculoskeletal discomforts. This study examined the associations among 3 factors, psychosocial work factors, work stress and musculoskeletal discomforts. These associations were examined via a questionnaire survey on 30 office workers (at a university in Malaysia), whose jobs required an extensive use of computers. The questionnaire was distributed and collected daily for 20 days. While the results indicated a significant relationship among psychosocial work factors, work stress and musculoskeletal discomfort, 3 psychosocial work factors were found to be more important than others in both work stress and musculoskeletal discomfort: job demands, negative social interaction and computer-related problems. To further develop study design, it is necessary to investigate industrial and other workers who have experienced musculoskeletal discomforts and work stress.
Dermal absorption of chlorpyrifos (CPF), an organophosphate (OP) pesticide, is important because of its popular use. Stress has been reported to exacerbate neurotoxic effects of certain OP pesticides; however, quantitative studies to corroborate this are not reported. This study correlates the changes in acetylcholinesterase (AChE) levels and neuronal counts in areas of the hippocampus to consecutive exposure of stress, heat and CPF. Male mice (60 days) were segregated into six groups: one control, one stress control, and four treated groups (n=10). CPF was applied in doses of 1/2 and 1/5 of dermal LD50 (E1 and E2) over the tail of mice under occlusive bandages for 3 weeks. Stress control [(s) C] mice were subjected to swim stress at 38 degrees C (6 mins/day, 3 weeks). (s) E1 and (s) E2 were subjected to swim stress before CPF application. Blood and brain AChE levels were estimated using a spectrofluorometric method (Amplex Red). Pyramidal neurons of the cornu ammonis of the hippocampus under Nissl stain from histological sections were counted per unit area of section and analyzed statistically using one way ANOVA. Swim stress at 38 degrees C aggravated reduction of serum AChE by dermal exposure to CPF by 19.7%. Neurons of CA3 and CA1 regions of the hippocampus showed significant reduction in neuronal counts in (s) E1 and (s) E2 groups compared to E1 and E2 groups. Whereas application of CPF 1/2 dermal LD50 (E1) showed significant reduction of neuronal counts only in the CA3 area.
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.
Floods are natural disasters that occur without much warning. Natural disasters can result in negative impact due to highly stressful event. Floods can cause mental and emotional disorders to the victims and could also induce stress and trauma either in the short or long terms. This research was carried out to recognize the psychological sequelae of floods and how to overcome them. This study describes the cross sectional descriptive pattern of flood victims in Johor. The DASS Test Questionnaire which is a measurement tool endorsed by the Family Development Institute, Ministry of Health Malaysia was used. We carried out the research in 3 districts of Johor which were the worst hit areas by the flood disaster. Twenty-three percent of the participants were males while 77% were females. The DASS Test Questionnaire showed that 13% were mildly depressed, 7% moderately depressed and 3% were severely depressed. It also revealed that 22% were mildly anxious, 19% moderately anxious, 5% severely anxious and 4% had very severe anxiety. On the stress scores, 15% suffered mild stress, 11% were moderately stressed while 2% were severely stressed. A committee to conduct the motivation programme for the state of Johor was formed by Jabatan Kesihatan Negeri Johor with the cooperation of the PROKEM committee from Hospital Permai, Johor Bahru. This committee headed by the Deputy Director of Health (Medical Division) attempted to overcome the psychological sequelae suffered by flood victims. The activities conducted by the PROKEM staff and staff from the Ministry of Health were monitored by the committee based at Hospital Permai, Johor Bahru. The Bilik Gerakan was in operation for 24 hours a day with meetings conducted every morning and evening to brief and debrief members of staff who were going to carry out the motivation programme. Feedback was also obtained from staff on their return from the various relief centres.
Introduction: This study aimed to explore the associated factors related to causes of stress and coping strategies among university students. Materials and Methods: As a focus group discussion, it was universal sampling, conducted among 39 of Medical Science and Biomedicine students on their second semester from Management and Science University (MSU), Shah Alam, Malaysia. Three issues were discussed: firstly, how they define the stress; secondly, what the most important causes of stress in their life are; and thirdly, how they cope with stress. Verbal consent was obtained from all participants. Due to the small sample size, the data was analyzed manually. Results: Total of participants were 39 students, their age ranged from 21 to 26 years. Seventeen (43.6%) of the students were 21 years old and the majority were female 31 (79.5%). The
most important causes of stress reported by the students were financial, lack of sleep, and family problems. In terms of coping with stress, the students were able to describe a variety of strategies to cope with their stressful situations. These included counseling services, doing meditation, sharing of problems, getting adequate sleep, and going out with friends. Conclusion: Most of the students defined stress as “a mental condition”. Lack of sleep, financial, and family problems were the most causes of stress among students. The students were able to identify some strategies to cope with stress.
Quantitative immunohistochemical methods were used to assess activation of the hypothalamo-hypophyseal-adrenocortical system at the level of its central component - the adenohypophysis - in the growing body during chronic exposure to psychoemotional stressors of different strengths. Sprague-Dawley rats aged 30 days were subjected to "mild" or "severe" immobilization stress for 5 h per day for seven days. Animals were decapitated at the end of the last stress session and the endocrine glands (hypophysis, adrenals) were harvested, weighed, and embedded in paraffin; sections were stained with hematoxylin and eosin, and also immunohistochemically using monoclonal antibodies to adrenocorticotropic hormone (ACTH) and proliferating cell nuclear antigen (PCNA) following by automated image analysis. These studies showed that stress-associated hyperplasia of corticotropocytes in rats of pubertal age was due more to the differentiation of existing immature precursor cells than to cell proliferation.
OBJECTIVES: To determine first year dental students' perceptions of intimidation by instructors and bullying by fellow students.
METHODS: Data were collected through a cross-sectional survey of first year dental students from seven dental schools representing five countries; one each from Romania, South Africa, Australia and the U.S.A., and three from Malaysia. Self-report questionnaires were administered to participants at least six months after they had commenced their dental degree course during 2005-6.
RESULTS: Over a third (34.6%) reported that they had been intimidated or badly treated by their tutors/instructors and 17% reported that they had been bullied or badly treated by their fellow students in the recent past. There were statistically significant differences in reports of intimidation by instructors between the different dental schools. Intimidation by instructors was associated with a history of medication use for stress, anxiety and depression, and perceived stress in the past month. There were no statistically significant variations in reports of bullying by fellow students between different dental schools. Bullying by fellow students was associated with dieting to lose weight, self-reported general health and perceived stress.
CONCLUSIONS: This multi-national study highlights that intimidation and bullying is prevalent within dental teaching and training environments. Future research is needed to explore their impact on students' wellbeing and academic progress as well as on patient care.
CLINICAL IMPLICATIONS: Dentists are the best recruiters for the profession. If the dental school experience is a negative one it can have significant impact on the future of the profession
A cross-sectional study on organizational factors that influences job stress was carried out among Medical Laboratory Technologists (MLT) in Klang Valley's Hospitals. There were three organizational factors that were measured, interpersonal factor, job condition and career development. A total of 249 respondents participated in this study, 126 were from the private hospitals and 123 from the government hospitals. The prevalence of stress was found higher in the private hospitals with the percentage of 16.7% compared to the government hospitals of 15.4%. All three organizational factors were significantly associated with job stress (interpersonal factor p <0.001, job condition p<0.001 and career development p < 0.001). Management team in hospitals as well as the laboratory managers should introduce stress prevention programmes to assist MLTs in stress management.
The Nursing Stress Scale (NSS) has been shown to be a valid and reliable instrument to assess occupational stressors among nurses. The NSS, which was previously used in the English version, was translated and back-translated into Bahasa Melayu. This study was conducted to assess the reliability of the Bahasa Melayu version of the NSS among nurses for future studies in this country. The reliability of the NSS was assessed after its readministration to 30 nurses with a 2-week interval. The Spearman coefficient was calculated to assess its stability. The internal consistency was measured through 4 measures: Cronbach's α, Spearman-Brown, Guttman split-half, and standardized item α coefficients. The total response rate was 70%. Test-retest reliability showed remarkable stability (Spearman's ρ exceeded .70). All 4 measures of internal consistency among items indicated a satisfactory level (coefficients in the range of .68 to .87). In conclusion, the Bahasa Melayu version of the NSS is a reliable and useful instrument for measuring the possible stressors at the workplace among nurses.
Having children with intellectual disability can be stressful for most parents. Currently there are very few studies focusing on parenting stress among mothers of children with Down syndrome (DS) in Asia. The present study examined the level of parenting stress experienced by Malaysian mothers of children with DS and evaluated the child and maternal factors that contributed to parenting stress based on Hill's ABC-X Model (Hill 1949).
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.
Distress has become a major issue in cancer population. Patients may suffer from either physical,psychological distress or both. Cancer patients who are undergoing chemotherapy are more likely to experience psychological distress. This could be due to the negative effects of chemotherapy agents, the uncertainty of post-treatment, and the occurrence of psychosocial problems. As a result, the patient may experience a normal reaction such as sadness or may develop common psychiatric disorders such as depression and anxiety.
