    Hatami M, Mohd Taib MN, Jamaluddin R, Abu Saad H, Djazayery A
    Appetite, 2013 Jan;60(1):27-32.
    PMID: 23103548 DOI: 10.1016/j.appet.2012.10.014
    OBJECTIVE: Several studies indicated that techniques to change body weight and appearance were prevalent and different among adolescents. The aim of the study, therefore, was to assess differences in frequency and type of body change techniques used among adolescents by sex and body weight status.

    METHODS: A sample of 758 adolescents aged 12-18 years were recruited from private and public schools in Tehran. Information about socio-demographic background and body change techniques were collected via a self-administered questionnaire.

    RESULTS: A high percentage of adolescents used body change techniques frequently to alter their body appearance. Girls changed normal eating pattern significantly (p=0.007) to lose weight more frequently than boys while boys used this method significantly (p=0.01) to gain weight more frequently than girls. Overweight/obese adolescents exercised significantly to change muscle size (p=0.03) and changed normal diet to lose weight (p<0.001) more frequently than normal weight adolescents. The relation between sex and body weight status with body change techniques (p<0.0) implied that male and female adolescents especially overweight/obese adolescents were frequently trying to change their body appearance.

    CONCLUSION: Significant differences existed in using body change techniques according to sex and body weight status and these should be considered in obesity prevention programs for adolescents.

    PMID: 23077858
    The World Health Organization (WHO) estimates that injury will be the second leading cause of morbidity of disease burden worldwide by the year 2020. We conducted a community-based survey to determine the prevalence of recent illness and injury, in Malaysia. The survey was a cross sectional population-based household survey conducted using face to face interviews. The information was on self-reported recent illness and injury (SRRII) over the previous 2 weeks. This study was conducted during April - August 2006 and as a part of the third National Health and Morbidity Survey of Malaysia. A total of 56,710 respondents were interviewed with a response rate of 98.2% (55,660/56,710). The overall prevalence of combined SRRII was 23.6%; for injuries the prevalence was 3.1%. The groups with the highest SRRII were children 0-5 years old (31.2%), males (24.3%), Indians (26.9%), those with secondary education level (22.9%), those earning RM 1,000/ month (25.0%) and rural dwellers (25.5%). Age, sex, ethnicity, and locality were significantly associated with SRRII while monthly household income and educational level were marginally associated. On multivariate analysis, age, gender, race, ethnicity, education, income and locality were significantly associated with SRRII. The most common reported recent illness was related to the respiratory system (42.0%). The information obtained from this survey is useful to policy makers in the Ministry of Health to review and strengthen existing health programs.

  5. Life events and stress: do older men and women in Malaysia cope differently as consumers?
    Ong FS, Phillips DR, Chai ST
    J Cross Cult Gerontol, 2013 Jun;28(2):195-210.
    PMID: 23652824 DOI: 10.1007/s10823-013-9190-9
    The study of major life events and their effects on well-being has considerable relevance for scientific disciplines and policy making in understanding the consumer behaviour of older people. There is evidence of differences in reactions to and coping with stress between males and females but relatively little knowledge about such gender differences amongst older people, especially in middle-income countries. This study of older Malaysians looked at both coping strategies and gender differences in reactions to stress when people are confronted with certain life events. Seventeen major life events were used in interviews with 645 respondents aged 50 years or older in five major urban areas in Peninsular Malaysia. The analysis showed older women tended to experience higher levels of chronic stress than older men. They also had more health problems, had lower levels of self-esteem and were less satisfied with life. Whilst the results showed little support for gender differences in coping behaviours, stress had a significant influence on the way older men and women change store preferences. A hypothesis that older women would use more emotion-focused coping strategies was not supported. Knowledge of how older Malaysians cope with life events and stress and especially in this instance with regard to consumption behaviour, is likely to be of considerable academic and policy related interest.

  6. Review article: Use of renal registry data for research, health-care planning and quality improvement: what can we learn from registry data in the Asia-Pacific region?
    Lim TO, Goh A, Lim YN, Morad Z
    Nephrology (Carlton), 2008 Dec;13(8):745-52.
    PMID: 19154324 DOI: 10.1111/j.1440-1797.2008.01044.x
    We review renal registry data from the Asia-Pacific region with an emphasis on their uses in health care and in dialysis care in particular. The review aims to demonstrate the information value of registry data. While renal registry provides a useful data resource for epidemiological research, there are severe methodological limitations in its application for analytical or therapeutic research. However, it is the use of renal registry data for public health and health-care management purposes that registry really comes into its own, and it is primarily for these that governments have invested in national patient and disease registries. We apply data from several renal registries in the Asia-Pacific region to illustrate its wide application for planning dialysis services, for evaluating dialysis practices and health outcomes, with a view to improving the quality of dialysis care. In the course of preparing the review, we have found that the quality and accessibility of renal registry data were highly variable across the region. Given the value of renal registry, every country in the Asia-Pacific region should establish one or should ensure that their current registries are better resourced and developed. Greater data sharing and collaboration among registries in the region could help advance the nephrology to serve our patients better.

  7. Molecular analysis of Ixodes granulatus, a possible vector tick for Borrelia burgdorferi sensu lato in Taiwan
    Chao LL, Wu WJ, Shih CM
    Exp Appl Acarol, 2009 Aug;48(4):329-44.
    PMID: 19184580 DOI: 10.1007/s10493-009-9244-4
    The genetic identity of Ixodes granulatus ticks was determined for the first time in Taiwan. The phylogenetic relationships were analyzed by comparing the sequences of mitochondrial 16S ribosomal DNA gene obtained from 19 strains of ticks representing seven species of Ixodes and two outgroup species (Rhipicephalus sanguineus and Haemaphysalis inermis). Four major clades could be easily distinguished by neighbour-joining analysis and were congruent by maximum-parsimony method. All these I. granulatus ticks of Taiwan were genetically affiliated to a monophyletic group with highly homogeneous sequences (92.2-99.3% similarity), and can be discriminated from other Ixodes species and other genera of ticks with a sequence divergence ranging from 11.7 to 30.8%. Moreover, intraspecific analysis revealed that two distinct lineages are evident between the same species of I. granulatus ticks collected from Taiwan and Malaysia. Our results demonstrate that all these I. granulatus ticks of Taiwan represent a unique lineage distinct from the common vector ticks (I. ricinus complex) for Borrelia burgdorferi spirochetes.

    Sasidharan S, Uyub AM
    Trans R Soc Trop Med Hyg, 2009 Apr;103(4):395-8.
    PMID: 19211121 DOI: 10.1016/j.trstmh.2008.11.021
    Helicobacter pylori infection is recognized as being strongly associated with chronic gastritis, duodenal ulceration and, probably, gastric carcinoma. Seroepidemiological studies have shown that a large proportion of healthy people have antibodies against H. pylori. A serological study was conducted in asymptomatic healthy blood donors in Northern Peninsular Malaysia to assess the seropositivity for H. pylori and to investigate the relationship with ethnic group, gender, ABO blood group and age. A total of 5370 serum samples collected from 3677 male and 1693 female donors in different age groups, and who had no gastrointestinal complaints, were studied with an in-house ELISA for the presence of H. pylori IgG and IgA antibodies. Seven hundred and sixty subjects (14.2%) were seropositive. The overall seropositivity did not differ with ethnicity, gender, ABO blood group and age among asymptomatic healthy blood donors in Northern Peninsular Malaysia.

    PMID: 19058591
    A cross-sectional study was carried out to determine the current prevalence of protein-energy malnutrition (PEM) among Orang Asli schoolchildren and to investigate the potential predictors of malnutrition. A total of 241 (120 males and 121 females) Orang Asli schoolchildren age 7-12 years living in remote areas of Pos Betau, Pahang participated voluntarily in this study. Anthropometric and socioeconomic data were collected and the children were screened for intestinal parasitic infections. The overall prevalences of mild and significant underweight conditions were 52.3% and 37.3%, respectively, and the prevalences of mild stunting and wasting were 43.6% and 43.1%, respectively, while the prevalences of significant stunting and wasting were 43.6% and 5.6%, respectively. There was a significant association between gender (male) and malnutrition (p = 0.029). The results also showed a higher prevalence of stunting among children age < or = 10 years than in older children (p = 0.001). Other independent variables, including socioeconomic status and intestinal parasitic infections, had no significant associations with malnutrition indices. PEM is prevalent among schoolchildren in rural Malaysia and therefore of public health concern since PEM diminishes immune function and impairs cognitive function and educational performance. School-based programs of prevention through health education and interventions should be considered as an essential part of measures to improve the quality of life of schoolchildren in rural Malaysia.

    Nicotine Tob Res, 2008 May;10(5):907-15.
    PMID: 18569766 DOI: 10.1080/14622200802027172
    Roll-your-own (RYO) cigarette use has been subject to relatively limited research, particularly in developing countries. This paper seeks to describe RYO use in Thailand and Malaysia and relate RYO use to smokers' knowledge of the harmfulness of tobacco. Data come from face-to-face surveys with 4,004 adult smokers from Malaysia (N = 2,004) and Thailand (N = 2000), collected between January and March 2005. The prevalence of any use of RYO cigarettes varied greatly between Malaysia (17%) and Thailand (58%). In both countries, any RYO use was associated with living in rural areas, older average age, lower level of education, male gender, not being in paid work, slightly lower consumption of cigarettes, higher social acceptability of smoking, and positive attitudes toward tobacco regulation. Among RYO users, exclusive use of RYO cigarettes (compared with mixed use) was associated with older age, female gender (relatively), thinking about the enjoyment of smoking, and not making a special effort to buy cheaper cigarettes if the price goes up. Finally, exclusive RYO smokers were less aware of health warnings (RYO tobacco carries no health warnings), but even so, knowledge of the health effects of tobacco was equivalent.

    Mellor D, Yeow J, Mohd Hapidzal NF, Yamamoto T, Yokoyama A, Nobuzane Y
    Child Psychiatry Hum Dev, 2009 Dec;40(4):527-41.
    PMID: 19449100 DOI: 10.1007/s10578-009-0142-0
    Childhood cruelty to animals is a symptom of conduct disorder that has been linked to the perpetration of violence in later life. Research has identified several factors associated with its etiology, including social factors. However, no cross-cultural studies on this phenomenon have been reported. This study investigated childhood cruelty to animals in Japan, Australia and Malaysia. Parents of 1,358 children between the ages of 5 and 13 years completed the Children's Attitudes and Behaviours towards Animals questionnaire (CABTA) which assesses Typical and Malicious Cruelty to animals. Analyses revealed no overall differences between children from these countries on either scale. However, younger boys were more likely to be cruel than younger girls in each country, and younger children in Australia and Japan were more likely to be cruel that older children in those countries. The findings are discussed in relation to previous research, and recommendations for future studies are suggested.

  13. Serum folate concentration, cognitive impairment, and DNA damage among elderly individuals in Malaysia
    Lee LK, Shahar S, Rajab N
    Nutr Res, 2009 May;29(5):327-34.
    PMID: 19555814 DOI: 10.1016/j.nutres.2009.05.006
    The notion that dietary factors affect cognitive function and subsequently the risk of dementia has increased over the years from a global viewpoint. Because low folate intake has been described to impair cognitive function, we tested the hypothesis that low serum folate concentration is associated with cognitive impairment and an attenuated increase in DNA damage. We investigated the relationship between serum folate concentration, cognitive impairment, and DNA damage among elderly people attending health clinics in Klang Valley, an urban area in Malaysia. Two hundred thirty-two participants, composed of 115 men (49.6%) and 117 women (50.4%), were involved; none of the patients were diagnosed with neuropsychiatric problems, nor where they terminally ill. Sociodemography and health variables were assessed through face-to-face interview. Cognitive impairment review was conducted through an Elderly Cognitive Assessment Questionnaire. The estimation of dietary intake, serum folate concentration, and DNA damage was individually analyzed using validated Dietary History Questionnaires, immunoassay methods, and an Alkaline Comet Assay study (10 mL of peripheral venous blood), respectively. Results indicated that more men had cognitive impairment (33.0%) and DNA damage (27.0% for percentage DNA in tail, 22.6% tail moment) compared with women (25.6%, 15.4%, and 15.4%, respectively) (P < .05 for all parameters), recording an average folate deficiency value of 13.9% (0.2% higher than women). Multivariate binary logistic regression analysis outlined the association of cognitive impairment with older age (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.35-5.57), smoking habits (OR, 5.12; 95% CI, 2.48-10.57), poor serum folate concentration (OR, 3.46; 95% CI, 1.26-9.52), and DNA damage (percentage DNA in tail) (OR, 13.70; 95% CI, 1.36-138.29). In conclusion, this study highlighted the important role of serum folate concentration for cognitive function and provided a concise picture regarding the elevated levels of oxidative DNA damage in peripheral lymphocytes.

    Lightning strike is a natural phenomenon with potentially devastating effects and represents one of the important causes of deaths from environmental phenomena. Almost every organ system may be affected as lightning current passes through the human body taking the shortest pathways between the contact points. A 10 years retrospective study (1996-2005) was conducted at University Hospital Kuala Lumpur (20 cases) also including cases during last 3 years from Hospital Tengku Ampuan Rahimah, Klang (7 cases) from the autopsy reports at Forensic Pathology Units of these 2 hospitals. Both these hospitals are attached to University of Malaya. There were 27 fatal cases of lightning strike with male preponderance(92.59%) and male to female ratio of 12.5:1. Majority of victims of lightning strike were from the age group between 30 and 39 years old. Most of the victims were foreign workers. Indonesians workers contributed to 59.26% of overall cases. Majority of them were construction workers who attributed i.e.11 of 27 cases (40.74%). Most of the victims were brought in dead (37.04%). In majority of the cases the lightning incidence occurred in the evenings, with the frequency of 15 of 27 cases (62.5%). The month of December represented with the highest number of cases (5 cases of 23 cases); 2004 had the highest incidence of lightning strike which was 5 (19.23%). Lightning strike incidence occurred when victims had taken shelter (25.9%) under trees or shades. Lightning strike in open areas occurred in 10 of 27 cases (37.0%). Head and neck were the most commonly affected sites with the incidence of 77.78% and 74% respectively in all the victims. Only 29.63% of the cases presented with ear bleeding.

  15. Genetic susceptibility to childhood acute lymphoblastic leukemia shows protection in Malay boys: results from the Malaysia-Singapore ALL Study Group
    Yeoh AE, Lu Y, Chan JY, Chan YH, Ariffin H, Kham SK, et al.
    Leuk. Res., 2010 Mar;34(3):276-83.
    PMID: 19651439 DOI: 10.1016/j.leukres.2009.07.003
    To study genetic epidemiology of childhood acute lymphoblastic leukemia (ALL) in the Chinese and Malays, we investigated 10 polymorphisms encoding carcinogen- or folate-metabolism and transport. Sex-adjusted analysis showed NQO1 609CT significantly protects against ALL, whilst MTHFR 677CT confers marginal protection. Interestingly, we observed that NQO1 609CT and MTHFR 1298 C-allele have greater genetic impact in boys than in girls. The combination of SLC19A1 80GA heterozygosity and 3'-TYMS -6bp/-6bp homozygous deletion is associated with reduced ALL risk in Malay boys. Our study has suggested the importance of gender and race in modulating ALL susceptibility via the folate metabolic pathway.

    PMID: 21592136 DOI: 10.1111/j.1423-0410.2011.01507.x
    Appropriate screening for irregular red-cell antibodies is essential for ensuring transfusion compatibility and for antenatal management of mothers at risk of haemolytic disease of the foetus and newborn. Screening for all relevant antibodies is, however, limited by screening cells that do not express antigens present in the patient and donor population. Technology to artificially incorporate antigens into red cells is currently available and may be an option for customizing screening cells.

    The rapid expansion of the aged population in Malaysia is expected to greatly increase the number of persons with dementia in the country. However, data on dementia prevalence at the national level is lacking, and little is known about the sociodemographic risk factors and correlates of dementia. This paper describes a nationwide study of dementia prevalence and its sociodemographic risk factors and health correlates among older Malaysians.
