Dengue is a mosquito-borne viral disease endemic in many countries in the tropics and sub-tropics. The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths.
The Women's Health and Life Experiences questionnaire measures the prevalence, health implications, and risk factors for domestic violence. This cross-sectional study was conducted to determine the validity and reliability of the Malay version of World Health Organization (WHO) Women's Health and Life Experiences Questionnaire. Construct validity and reliability assessment of the Malay version of the questionnaire was done on 20 specific items that measure four types of intimate partner violence (IPV) act; controlling behaviors (CB), emotional violence (EV), physical violence (PV), and sexual violence (SV), which were considered as the domains of interest. Face-to-face interviewing method was used for data collection. A total of 922 women completed the interviews. The results showed that exploratory factor analysis of four factors with eigenvalues above 1 accounted for 63.83% of the variance. Exploratory factor analysis revealed that all items loaded above 0.40 and the majority of items loaded on factors that were generally consistent with the proposed construct. The internal consistency reliability was good. The Cronbach's α values ranged from 0.767 to 0.858 across domains. The Malay version of WHO Women's Health and Life Experiences Questionnaire is a valid and reliable measure of women's health and experiences of IPV in Malaysia.
The disorder of autism is widely recognised throughout the world. However, the diagnostic criteria and theories of autism are based on research predominantly conducted in Western cultures. Here we compare the expression of autistic traits in a sample of neurotypical individuals from one Western culture (UK) and two Eastern cultures (India and Malaysia), using the Autism-spectrum Quotient (AQ) in order to identify possible cultural differences in the expression of autistic traits. Behaviours associated with autistic traits were reported to a greater extent in the Eastern cultures than the Western culture. Males scored higher than females and science students scored higher than non-science students in each culture. Indian students scored higher than both other groups on the Imagination sub-scale, Malaysian students scored higher than both other groups on the Attention Switching sub-scale. The underlying factor structures of the AQ for each population were derived and discussed.
There was considerable evidence that a subject's psychological status may influence respiratory sensations and that some subjects may experience respiratory symptoms regardless of the presence of a respiratory disease. The objective of this study was to determine the association between occupational stress and respiratory symptoms among lecturers. This cross sectional study was conducted in Universiti Putra Malaysia, involved 61 lecturers from various faculties. Job Content Questionnaire (JCQ) and questionnaires based on American Thoracic Society were used to collect the data on socio-demography, stress level and respiratory symptoms. High level of occupational stress (high strain) was determined among 16 of the respondents (26.2%). Breathlessness was the common symptom experienced by the respondents. Female lecturers were significantly experienced high stress level compared to male (p=0.035). They were also significantly having more breathlessness symptom compared to male lecturer (p=0.011). Study highlighted in study population, gender plays a significant role that influenced level of occupational stress and also gender has role in resulting occupational stress level and respiratory symptoms. There was no significant association between occupational stress and respiratory symptoms. It can be concluded that this group of lecturers of Universiti Putra Malaysia did not experienced high occupational stress level. Occupational stress level was not statistically significantly associated with all respiratory symptoms being studied.
Sleep disordered breathing (SDB) is increasingly being diagnosed in children. However, there is no prevalence study done in Malaysia. The study objective was to evaluate the prevalence of SDB symptoms based on parental reports and associated risk factors among Malay school children aged 6 to 10 years old in a primary school using a translated University Michigan Paediatric Sleep Questionnaire (Malay UM-PSQ). The children whose parents responded to the questionnaire and consented were examined, documenting height, weight, skin fold thickness, neck and abdominal circumference, tonsillar size, nostril examination and presence of micrognathia or retrognathia. There were 550 respondents. The prevalence of parental report of SDB symptoms was 14.9 % (95 % CI 11.9, 17.9). Two hundred and eighty-five (51.8%) school children were males with mean age of 8.5 years (SD 1.1). The associated risk factors for SDB symptoms are male, obesity, large neck and waist circumference, positive history of asthma, history of recurrent tonsillitis, enlarged tonsil (> 4+) and enlarged nasal turbinate. Multivariate analysis showed that male gender is the only significant independent risk factor of SDB symptoms
Unmet need as a significant factor affecting quality of life in later life has recently received considerable attention in gerontological research. The main aim of this study was to identify the prevalence, predicting factors, and negative consequence of unmet need among older Malaysians. The findings may be useful to reduce unmet need and the burden of its adverse consequence. The sample for this study consists of 400 functionally disabled elderly people aged 60 and over was obtained from a large national survey. Unmet need was operationally defined based on Manton's (1989) criteria. The findings from the present study showed about 18.0% of functionally disabled older Malaysians suffer from unmet need. Logistic regression revealed that gender (being male) and chronic health conditions are statistically associated with increased odds of unmet need after adjusting for other possible risk factors. Further results indicated that unmet need statistically increases odds of fall as a negative consequence of unmet need. The high prevalence rates of unmet need among disabled elderly men and chronically ill older persons suggest that policy makers should pay more attention to this vulnerable group to achieve good quality of life. The implications and limitations of the present study are discussed.
This study was conducted to investigate pervasiveness of the musculoskeletal disorder (MSD) among staffs in a specialized healthcare centre. Sixty-eight staffs from three departments namely Cardiovascular Lab (CVL), Nuclear Radiology, and General Radiography were recruited in this study. A modified Nordic Musculoskeletal Questionnaire (NMQ) was distributed among study population. The result shows that the prevalence of MSD was highest in lower back (88.2%), neck (76.5%) and shoulder (60.3%) for the past 12 months followed by lower back and elbow (44.1%), and wrist (39.1%) correspondingly, for the past 7 days. Present results suggest that healthcare professionals - radiographers, patient assistants and nurses incurs MSD risks through work tasks as well as psychosocial factors. These include awkward posture during patient handling, workload, work stress and time pressure. Therefore, an ergonomics improvement on the job design and workspace are needed in order to reduce the MSD risks.
This study examines the sociodemographic factors associated with daily fruit and vegetable (FV) consumption in Malaysia. Based on a cross-sectional sample of 2447 individuals from the Malaysia Non-Communicable Disease Surveillance-1, a multivariate sample selection system is developed and estimated, to accommodate high frequencies of daily FV consumption and the days of servings among nondaily consumers. Results indicate that the authors' attempt to account for endogenous sample selectivity and cross-equation correlations is justified. There exist positive correlations between FV consumption likelihoods and longer work hours, higher levels of education, high income, female gender, nonsmoking status, and being from East Malaysia. Among nondaily consumers, those with longer work hours, singles, and people with diabetes are less inclined to eat fruits on more days. Overall, higher-educated, affluent people, nonsmokers, and East Malaysians display more days of FV consumption. Based on these outcomes, several policy implications are recommended vis-à-vis FV consumption patterns in Malaysia.
This study aimed to assess the variability of the lower third molar (tooth 38 and 48) development in Northeast Malaysian population with respect to the side of dentition, to generate age prediction models and to compare the outcome with other studies. A total of 1080 orthopantomograms of Northeast Malaysian population aged between 14 and 25 years (540 males and 540 females) from the Hospital Universiti Sains Malaysia's archive which met the inclusion and exclusion criteria were selected and the maturity stages of tooth 38 and 48 were scored using Demirjian's stages (A-H). The findings showed a wide variation of the development of lower third molars in the Northeast Malaysian population. The roots developed earlier in males than in females. The development of the dentition on opposite sides of the mandible was synchronously in females and males. A multiple regression analysis shows that 71.1% of variance in age was explained by sex and developmental stage of tooth 48. An age prediction model was generated from the regression analysis: [Age = 7.117 + 1.907*(stage of tooth 48) - 0.432*(sex)] with mean prediction errors between -0.17 to 3.14 years. The obtained data in the current study are useful for references and determining age of unidentified human remains for identification investigation.
Childhood nocturnal enuresis (NE) and incontinence has been shown to be associated with increased behavioural problems and reduced self-esteem (SE) in Western populations. The impact on Asian children, however, is not known. This study investigates the relationship between SE and monosymptomatic NE in Malaysian children aged 6 to 16 years.
Food variety scores (FVS) and dietary diversity scores (DDS) were estimated based on foods consumed weekly by 285 Malaysian households using a food frequency questionnaire. The scoring system of FVS and DDS was based on a scale of 0-7 and 0-6 respectively. The mean household FVS and DDS was 164.1 ± 93 and 6 ± 0.4. The age of respondents (husbands or wives; p < .01), sex (p < .05), and household food expenditure (p < .01) had a significant influence on both FVS and DDS. The food-intake pattern of Malaysian households showed that their typical diets had high protein and energy-based foods.
The aim of this study was to assess nutritional supplement use among fitness club participants in Tehran, Iran. A cross sectional study was conducted in 24 fitness clubs throughout the city of Tehran, Iran. A total of 1625 fitness club participants were recruited to participate in this study. They were asked to complete a self-administered pre-tested questionnaire. Descriptive statistics and chi-square test were performed to determine the characteristics of participants, reasons for supplement use, sources of information and also the influential advisors regarding nutritional supplement use. A high prevalence rate of nutritional supplement use (66.7%) was reported. Overall, multivitamin-mineral (43.8%) and iron tablets (30.5%) were the common nutritional supplements used and only a small number of participants used illegal substances (0.5%). Younger participants were more likely to use ergogenic aids, whereas, older participants were more likely to use vitamin D. Males were more likely than females to use creatine and amino acids, whereas, iron tablets and mint water were more common among females. Also, males were more likely to use nutritional supplements for increasing energy, whereas, females were more likely to use nutritional supplements for nutritional deficiencies. In conclusion, a high prevalence rate of nutritional supplement use was seen among participants.
There is a lack of data on tobacco use in the Syrian Arab Republic. This cross-sectional questionnaire survey estimated the prevalence of smoking among university students in Damascus and identified factors related to smoking. Among the 583 respondents, the overall prevalence of cigarette smoking was 20.8%. The mean age of smokers [25 (SD 2.2) years] was significantly higher than non-smokers [21 (SD 1.8) years]. Smoking prevalence among males (26.1%) was significantly higher than among females (9.5%). However, female students consumed a significantly higher number of cigarettes per day than did males [mean 21 (SD 5) versus 9 (SD 2)]. The smoking prevalence among students in non-health faculties (27.8%) was significantly higher than that of health professional students (14.5%) and was higher among students living away from their families (27.8%) than those living with their families (16.2%). The study raised concerns about smoking in student residences and women's smoking patterns.
Designing a system for the elderly is crucial, as aging is associated with physiological changes that may impair perception, cognition and other social aspects; therefore, many aspects need consideration, especially in interface design. This study was conducted to develop a digital nutritional education package (WE Sihat) by following appropriate guidelines for elderly people to achieve better design interface and interaction. Touch-screen technology was used as a platform for user interaction. The nutritional content was based on previous nutrition studies and a lifestyle education package on healthy aging, which contains four modules. The questionnaires were distributed to 31 Malay subjects aged 60-76 years old, containing an evaluation about the overall content, graphics, design layout, colour, font size, audio/video, user-perceived satisfaction and acceptance levels. The findings showed positive feedback and acceptance. Most subjects agreed that the digital nutritional education package can increase their nutritional knowledge for a healthy lifestyle and is easy to use. The touch-screen technology was also well accepted by elderly people and can be used as a kiosk for disseminating nutrition education for healthy aging.
We contrasted demographic and clinical characteristics in transethnic schizophrenia populations from Australia (n=821), India (n=520) and Sarawak, Malaysia (n=298) and proposed cultural explanations for identified site differences. From these we aimed to identify candidate variables free from significant cultural confounding that are hence suitable for inclusion in genetic analyses. We observed five phenomena: (1) more individuals were living alone in Australia than India or Sarawak; (2) drug use was lower in India than Australia or Sarawak; (3) duration of untreated psychosis (DUP) was longer in India than Australia or Sarawak; (4) the rate of schizoaffective disorder was lower in India than Australia or Sarawak; and (5) age at psychosis onset (AAO) was older in Sarawak than Australia or India. We suggest that site differences for living arrangements, drug use and DUP are culturally confounded. The schizoaffective site difference likely results from measurement bias. The AAO site difference, however, has no obvious cultural or measurement bias explanation. Therefore, this may be an ideal candidate for use in genetic studies, given that genetic variants affecting AAO have already been proposed.
Psychological well-being as one of the most important indicators of successful aging has received substantial attention in the gerontological literature. Prior studies show that sociodemographic factors influencing elderly's psychological well-being are multiple and differ across cultures. The aim of this study was to identify significant sociodemographic predictors of psychological well-being among Malay elders.
The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay female children had higher formant frequencies than those of their male counterparts. However, no significant differences in all four formant frequencies were observed between the Malay male and female children in most of the vowels and age groups. Significant differences in all formant frequencies were found across the Malay vowels in both Malay male and female children for all age groups except for F4 in female children aged 12 years. Generally, the Malaysian Malay children showed a nonsystematic decrement in formant frequencies with age. Low levels of significant differences in formant frequencies were observed across the age groups in most of the vowels for F1, F3, and F4 in Malay male children and F1 and F4 in Malay female children.
BACKGROUND: Nearly four-fifths of estimated 1.1 million smokers live in low or middle-income countries. We aimed to provide national estimates for Nepal on tobacco use prevalence, its distribution across demographic, socio-economic and spatial variables and correlates of tobacco use.
METHODS: A secondary data analysis of 2006 Nepal Demographic and Health Survey (DHS) was done. A representative sample of 9,036 households was selected by two-stage stratified, probability proportional to size (PPS) technique. We constructed three outcome variables 'tobacco smoke', 'tobacco chewer' and 'any tobacco use' based on four questions about tobacco use that were asked in DHS questionnaires. Socio-economic, demographic and spatial predictor variables were used. We computed overall prevalence for 'tobacco smoking', 'tobacco chewing' and 'any tobacco use' i.e. point estimates of prevalence rates, 95% confidence intervals (CIs) after adjustment for strata and clustering at primary sampling unit (PSU) level. For correlates of tobacco use, we used multivariate analysis to calculate adjusted odds ratios (AORs) and their 95% CIs. A p-value < 0.05 was considered as significant.
RESULTS: Total number of households, eligible women and men interviewed was 8707, 10793 and 4397 respectively. The overall prevalence for 'any tobacco use', 'tobacco smoking' and 'tobacco chewing' were 30.3% (95% CI 28.9, 31.7), 20.7% (95% CI 19.5, 22.0) and 14.6% (95% CI 13.5, 15.7) respectively. Prevalence among men was significantly higher than women for 'any tobacco use' (56.5% versus 19.6%), 'tobacco smoking' (32.8% versus 15.8%) and 'tobacco chewing' (38.0% versus 5.0%). By multivariate analysis, older adults, men, lesser educated and those with lower wealth quintiles were more likely to be using all forms of tobacco. Divorced, separated, and widowed were more likely to smoke (OR 1.49, 95% CI 1.14, 1.94) and chew tobacco (OR 1.36, 95% CI 0.97, 1.93) as compared to those who were currently married. Prevalence of 'tobacco chewing' was higher in eastern region (19.7%) and terai/plains (16.2%). 'Tobacco smoking' and 'any tobacco use' were higher in rural areas, mid-western and far western and mountainous areas.
CONCLUSIONS: Prevalence of tobacco use is considerably high among Nepalese people. Demographic and socioeconomic determinants and spatial distribution should be considered while planning tobacco control interventions.
Malaysian students ages 12 to 15 years (N = 330; 165 girls, 165 boys) took the Australian Institute of Sport Talent Identification Test (AIST) and the Balance and Movement Coordination Test (BMC), developed specifically to identify sport talent in Malaysian adolescents. To investigate evidence for general aptitude ("g") in motor ability, a higher-order factor analysis was applied to the motor skills subtests from the AIST and BMC. First-order principal components analysis indicated that scores for the adolescent boys and girls could be described by similar sets of specific motor abilities. In particular, sets of skills identified as Movement Coordination and Postural Control were found, with Balancing Ability also emerging. For the girls, a factor labeled Static Balance was indicated. However, for the boys a more general balance ability labeled Kinesthetic Integration was found, along with an ability labeled Explosive Power. These first-order analyses accounted for 45% to 60% of the variance in the scores on the motor skills tests for the boys and girls, respectively. Separate second-order factor analyses for the boys and girls extracted a single higher-order factor, which was consistent with the existence of a motoric "g".
