We synthesised evidence on biological correlates of psychological stress in hospital-based healthcare professionals, and examined whether there was evidence of consistent biological changes. Electronic databases were searched for empirical studies; 16 articles (0.6%) met the inclusion criteria. Evidence of a relationship between indices of psychological stress and biological parameters was limited and inconsistent. There was some evidence of a consistent relationship between natural killer cells and lymphocyte subpopulations. Considerable heterogeneity in the methods used was seen. Future prospective studies examining the relationship between indices of psychological stress and natural killer cells, including lymphocyte subsets, is required.
The current study examined body satisfaction and the value of body size among adolescents in Australia, Fiji, Malaysia, Tonga, Tongans in New Zealand, China, Chile and Greece. In total, 2489 adolescent females and 2152 males participated in the study. The results demonstrated that males were more satisfied with their body than females. Males generally had a lower BMI than females, except for males in China and Malaysia. Attitudes towards large bodies for males and females varied by cultural group. These results demonstrate the strong cultural similarities in body satisfaction, but the differences that occur in relation to a large body.
Adolescents with type 1 diabetes mellitus are prone to have eating problems. This study aimed to determine factors of eating problems among this population in University Malaya Medical Centre. Fifteen adolescents who scored more than 20 marks in the Diabetes Eating Problem Survey - Revised questionnaire were invited for an in-depth interview. Questions were asked based on their questionnaire's response. The interview sessions were recorded, transcribed verbatim, and thematic analysis was used. Five main themes emerged: pressure, physiological factor, psychological factor, patient's low compliances to insulin intake and food control and fear. Early referral to child psychologist would prevent it from developing.
This community based cross-sectional study examined the prevalence and factors associated with depression among urban poor in Peninsular Malaysia. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depression. The prevalence of depression among the urban poor was 12.3%. Factors significantly associated with depression included respondents under 25 years old, male gender, living in the area for less than four years and those who do not exercise regularly. It is important to identify individuals with depression and its associated factors early because depression can severely affect the quality of life.
This study was designed to examine the relationships between problem-solving skills, hardiness, and perceived stress and to test the moderating role of hardiness in the relationship between problem-solving skills and perceived stress among 500 undergraduates from Malaysian public universities. The analyses showed that undergraduates with poor problem-solving confidence, external personal control of emotion, and approach-avoidance style were more likely to report perceived stress. Hardiness moderated the relationships between problem-solving skills and perceived stress. These findings reinforce the importance of moderating role of hardiness as an influencing factor that explains how problem-solving skills affect perceived stress among undergraduates.
Although medical mistrust (MM) may be an impediment to public health interventions, no MM scale has been validated across countries and the assessment of MM has not been explored using item response theory, which allows generalisation beyond the sampled data. We aimed to determine the dimensionality of a brief MM measure across four countries through Mokken analysis and Graded Response Modelling. Analysis of 1468 participants from UK (n = 1179), Ireland (n = 191), India (n = 49) and Malaysia (n = 49) demonstrated that MM items formed a hierarchical, unidimensional measure, which is very informative about high levels of MM. Possible item reduction and scoring changes were also demonstrated. This study demonstrates that this brief MM measure is suitable for international studies as it is unidimensional across countries, cross cultural, and shows that minor adjustments will not impact on the assessment of MM when using these items.
Engagement in health-promoting behaviors has been argued to be dependent on psychological factors in addition to simply having knowledge or access to resources. We systematically reviewed the evidence for the association between body (dis)satisfaction and health screening behaviors using six electronic databases and supplementary manual searches in the current study. To be included in the review, studies had to be empirical, in any language, and examined the potential link between body (dis)satisfaction and health screening. Findings from the final 16 quantitative and 12 qualitative studies generally suggest that people who were more satisfied or less dissatisfied with their bodies were more likely to engage in health screening. This review also highlighted key gaps in the literature such as the limited studies that included men as participants and the lack of examination of the underlying mechanisms and contingencies of the relationship between body (dis)satisfaction and health screening behaviors.
