  1. Characteristics of normal labour among different racial groups in Malaysia
    Lim MA, Wong WP, Sinnathuray TA
    Br J Obstet Gynaecol, 1977 Aug;84(8):600-4.
    PMID: 889748
    The characteristics of normal labour in 977 Malay, Chinese and Indian parturients were established from a retrospective study. Indian babies were found to be significantly smaller than Malay babies which were significantly smaller than Chinese babies (P less than 0-05, P less than 0-05). The mean duration of the first stage of labour taken from the time of admission to the labour ward was 3-4 hours in primiparae and 2-7 hours in multiparae. The mean durations of the second stage of labour were 23-7 minutes and 13-1 minutes respectively. Curves of mean dilatation of cervix and probit analysis at 80% revealed significant differences in the progress of normal labour in primiparae among the three racial groups. The Indian primiparae not only had a slower rate of cervical dilatation but seemed to reach the accelerated phase of dilatation later. No significant differences were noticed in the labours of multiparae.

    PMID: 1056826
    A dental health survey of 15,197 schoolchildren age 6-18 years was conducted in West Malaysia. The caries experience in the permanent teeth of the three racial groups, namely Malay, Chinese and Indian/Pakistani, showed a distinct variation. The prevalence was highest among the Chinese children, being about twice that of the Malay and Indian/Pakistani children. In the primary dentition, however, the caries experience in the three racial groups was comparable. An analysis of the factors contributing to the racial variation showed that dietary influence was not the only factor responsible. The possibility of a racial variation in caries susceptibility has been postulated. In the primary dentition the similar caries experience observed in the three groups of children was most probably due to the widespread occurrence of rampant caries which would heavily weight the dift score of the children in all three groups. The need to fluoridate the public water supply as an effective preventive measure is emphasized.

  4. Acid alpha-glucosidase in Malaysians. Population studies and the occurrence of a new variant
    Teng YS, Tan SG
    Hum. Hered., 1979;29(1):2-4.
    PMID: 367946
    Acid alpha-glucosidase from the placenta was electrophoretically surveyed in a total of 633 Malaysians, 236 of Malay, 261 of Chinese and 136 of Indian ancestries. A new variant, alpha-glucosidase 3-1 was observed in 1 Malay and 3 Indians. A polymorphism for this enzyme was observed among Indians, but in Chinese and Malays variants are rare. Phenotype 2-1 was observed once in a Chinese and once in a Malay.

    Med J Malaysia, 1975 Dec;30(2):88-92.
    PMID: 1228387
    In a study during 1972 of smoking habits of Malaysian medical students, smoking rates of medical students was seen to be higher than that of students in four other faculties in the University of Malaya. Male Malaysian medical students had higher smoking rates than their counterparts in Glasgow in 1971 (UM 20.3%, Glasgow 19.1%) but Malaysian females had very low smoking rates (male 25.2%, female 1.6%). Despite the fact that in the medical curriculum students are made aware of the scientific evidence on the health hazards of smoking, smoking rates were higher in students int their later years of study. Ethnicity was associate with smoking rates although father's smoking habit was not - and Malays had the highest smoking rates (malay 28.2%, chinese 16.3%, indian and others 23.5%).

    Cheah JS, Tambyah JA, Mitra NR
    Trop Geogr Med, 1975 Mar;27(1):14-6.
    PMID: 1169832
    During a routine medical examination of 5280 government employees (2736 males, 2544 females; age range 17 to 66 years; 3386 Chinese, 1252 Malays, 508 Indians and 134 other ethnic groups) diabetes was found in 31 (0.59%). The prevalence was higher in males (0.95%) than in females (0.20%). The highest prevalence was in the age-group 50 to 59 years (5.4%); at ages 30 to 66 years, the overall prevalence was 2.18%. The prevalence of diabetes is higher in Indians (2.76%) than in Chinese (0.30%) and Malays (0.48%); the difference is statistically significant, as it also is in the age-group 30 to 66 years (Indians 6.36%, Malays 1.39%, Chinese 0.9%). Of the 31 cases, only four were previously known and only nine were overwieght. The possible reasons for the higher prevalence of diabetes in Indians are discussed.

  9. Physical and cognitive domains of the Instrumental Activities of Daily Living: validation in a multiethnic population of Asian older adults
    Ng TP, Niti M, Chiam PC, Kua EH
    J Gerontol A Biol Sci Med Sci, 2006 Jul;61(7):726-35.
    PMID: 16870636
    BACKGROUND: We sought to assess the validity of the physical and cognitive domains of Lawton and Brody's Instrumental Activities of Daily Living (IADL) scale and its cross-cultural applicability across ethnic groups in an Asian population of community-living older adults.

    METHODS: Using data from a random population sample of noninstitutionalized Chinese, Malay, and Indian older adults 60 years old and older in Singapore (N = 1072), we modeled the dimensional structure of the 8-item IADL Scale using exploratory and confirmatory factor analyses, and assessed its convergent and divergent validity using known group differences and strengths of association.

    RESULTS: Factor analyses yielded two strong and reliable factors representing underlying physical and cognitive dimensions of IADL. The validity of the model was supported by the pattern of associations of the IADL with age, gender, education, self-reported health status, hospitalization, physical comorbidities, dementia and depression, and Mini-Mental State Examination (MMSE) scores. Notably, cognitive IADL showed a greater total effect on MMSE cognitive performance score than did physical IADL, with the effect of physical IADL on MMSE score mostly explained by cognitive IADL. Reasonably good cross-cultural validity was demonstrated among Chinese, Malays, and Indians, with strongest validity for Indians.

    CONCLUSION: The eight-item IADL Scale has physical and cognitive domains and is cross-culturally applicable. The cognitive IADL domain taps a set of activities directly related to cognitive functioning.

  10. Ethnic distribution of Chlamydophila pneumoniae antibodies in a Malaysian population and possible correlation with coronary heart disease
    Naidu BR, Ngeow YF, Pang T

    PMID: 12733835
    Chlamydophila pneumoniae, an important respiratory pathogen causing lower respiratory tract infections, has also been implicated in coronary heart disease (CHD). This study reports a cross-sectional, demographic, serological analysis of the prevalence of Chlamydophila pneumoniae antibodies in a multiracial Malaysian population. Generally, Malaysian Indians had the highest degree of seropositivity (58%) followed by the Chinese (54%) and the Malays (32%), results which were statistically significant (CI: 95%; p < 0.01). Interestingly, this trend was also reflected in the study group consisting of patients with acute myocardial infarctions (AMI) and chronic CHD. Again, the Indians were more frequently seropositive (65%), with more than 50% having IgG titres > or = 128. Comparatively, the Chinese and Malays showed 51 and 17% seropositivity respectively. These results were also statistically significant (CI: 95%; p < 0.01). Malaysian Indians are more commonly afflicted with CHD. A variety of factors have been suggested to explain this prevalence including diet, social habits, genetics and the possible role of infectious agents. This study notes an interesting association between this pattern of racial prevalence and the possible role of C. pneumoniae infections as a contributory/predisposing factor in the development of cardiovascular disease.

    APLAR Journal of Rheumatology, 2007;10(1):32-36.
    DOI: 10.1111/j.1479-8077.2007.00252.x
    Aim: To provide the first case series analysis for psoriatic arthritis (PsA) in Malaysia.
    Methods: Patient records were studied from rheumatology clinics in Universiti Kebangsaan Malaysia Hospital and Putrajaya Hospital in Malaysia.
    Results: Thirty-one patients from two rheumatology centres were studied. Thirteen patients (41.9%) were male and 18 patients (58.1%) were female. Nineteen patients (61.3%) were Malays, four (12.9%) were Chinese, seven (22.6%) were Indians and one (3.2%) was a Sikh. The majority of patients were in the >.50 years age-group (11 [35.5%]) followed by the 41-50 years age-group (10 [32.3%]). Thirteen patients (41.9%) had the disease since 41-50 years of age. Twenty-three patients (77.4%) had no family history of PsA. Twenty-three patients (74.2%) had psoriasis first, seven (22.6%) had arthritis first and one (3.2%) developed psoriasis and arthritis at the same time. Twenty-four patients (77.4%) had positive activity correlation for skin and arthritis. The majority of patients had symmetrical arthritis (20 [64.5%]) and chronic plaque-like lesions (22 [71.0%]). These patients were on NSAIDS and methotrexate (14 [45.2%]). One patient (3.6%) needed surgery for joint replacement.
    Conclusion: Patients who were diagnosed as having PsA were Malays, age group of more than 50, disease onset at 41-50 years of age, no family history, had symmetrical and chronic plaque lesions, had psoriasis first and needed NSAIDS and methotrexate.

    DOI: 10.4314/tjpr.v13i1.22
    Purpose: To evaluate knowledge and perceptions of osteoporosis among university students in Malaysia belonging to different age groups, gender and ethnicity.
    Methods: Using convenience sampling method, current study was conducted among students of University Sains Malaysia (USM), Pulau Penang, Malaysia. A pre-validated self-administered questionnaire was used to carry out the study.
    Results: The mean age of the participants was 24.61 ± 5.51 years. A majority, 401 (87 %), identified osteoporosis correctly as a disease that makes bones weak and fragile. Lack of milk and dairy products were identified by majority of participants (74 %) as a risk factor for osteoporosis while being petite (24 %) and family history (34.5 %) were the least identified risk factors. Female showed statistically higher knowledge score than males (243.89 versus 216.12, p = 0.02). Ethnicity (Malay: 228.32, Chinese: 264.46, Indian: 194.04, Others: 236.94, p = 0.00) and type of education (Hybrid: 225.99, Arts: 182.21, Science: 286.23, p = 0.00) were factors that correlated significantly with knowledge and perceptions of osteoporosis.
    Conclusion: This study demonstrates an urgent need for the implementation of educational and awareness programs for university students belonging to various age groups. Such programs should be designed on the basis of the parameters of health belief model. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.

  13. The study of clinical characteristics of gout patients on follow up in Rheumatology Clinic, Hospital Seremban. [Abstract]
    Mohd A, Gun SC, Das Gupta E, De'Souza B
    APLAR Journal of Rheumatology, 2006;9 Suppl 1:A89.
    Objective: To determine the epidemiological, clinical and laboratory features of the patients with gout, on follow up in Rheumatology Outpatient Clinic, Hospital Seremban.
    Methods: This was a retrospective study. Case notes of all our existing gout patients were reviewed, and data on demography, clinical features, associated conditions, and laboratory findings were noted.
    Results: 54 patients were studied, 48 (89%) were male and 6 (11%) were female at the ratio of M : F = 8:1, 30 (57%) of them had the onset of symptoms at their 3rd and 4th decades of life. The majority were the Malays 39 (72%), followed by the Indians 11 (20%) and the Chinese 4 (8%). Commonly associated conditions were hypertension in 37 (68.5%), obesity (BMI of 30 and above) in 36 (66.7%) and hyperlipidaemia in 36 (66.7%) of them. Mixed hyperlipidaemia (High TG and LDL cholesterol) were found in 19 (53%). Underlying history of diabetes mellitus 7 (13%), alcohol consumption 8 (15%), smoking habits 22 (40%) and family history of gout 18 (33%). Half of our patients 27 (50%) had at least 2 or more joints involvement. 28 (52%) of them had tophaceous gout. Among those with tophaceous gout, 18 (64%) had renal impairment with serum creatinine of .150mmol/l. 6 (31.5%) of the patients with renal impairment found to have renal calculi on ultrasonography.
    Conclusion: There was male predominance in our group of patients which was consistent with other reported epidemiological studies. Hypertension, mixed hyperlipidaemia and obesity were common associated conditions while diabetes mellitus, smoking and family history of gout were not. The majority of gout patients in our clinic were Malays and due to religious reasons, alcohol was not a common associated factor. Half of our patients had multiple joints involvement and more than half also had tophaceous gout. There was high incidence of renal impairment seen in patients with tophaceous gout. These could be due to delay in seeking medical treatment, present of renal calculi and possibly contributed by associated hypertension and diabetes mellitus.

    Hum Genet, 1979;53(1):87-90.
    PMID: 395099
    Human alcohol dehydrogenase ADH2 and ADH3 were investigated in liver and stomach specimens of Chinese and Indians from West Malaysia. Eight-nine percent of the Chinese carry the atypical ADH2 type, a proportion very similar to that reported in Japanese. However, among 43 Indian specimens there was not a single case of atypical ADH2. In Indians, the gene frequency of ADH13 is 0.64 and of ADH23 0.36, similar to the frequencies in Caucasians, whereas in Chinese, the gene frequency for ADH13 and ADH23 is 0.91 and 0.09, respectively. We also report some unusual enzymatic characteristics in the course of our study.

  15. Fulltext Risk factors for proteinuria in a large, multiracial, southeast Asian population
    Ramirez SP, McClellan W, Port FK, Hsu SI
    J Am Soc Nephrol, 2002 Jul;13(7):1907-17.
    PMID: 12089388 DOI: 10.1097/01.asn.0000018406.20282.c8
    The factors associated with proteinuria were examined in a large multiracial Asian population participating in a screening program aimed at the early detection of renal disease. Of 213,873 adults who participated, 189,117 with complete data were included. Malay race, increasing age, both extremes of body mass index (BMI), self-reported family history of kidney disease (FKD), and higher systolic and diastolic BP measurements (even at levels classified as being within the normal range) were independently associated with dipstick-positive proteinuria. The odds ratios (OR) for proteinuria increased progressively with age. There was a J-shaped relationship between BMI and proteinuria (OR of 1.3, 1.00, 1.3, 1.6, and 2.5 for BMI of < or =18.00, 23.00 to 24.99, 25.00 to 27.49, 27.50 to 29.99, and > or =30.00 kg/m(2), respectively, compared with BMI of 18.01 to 22.99 kg/m(2)). OR for proteinuria according to systolic and diastolic BP were significantly increased beginning at levels of 110 and 90 mmHg, respectively. In addition, the Malay race was associated with a significantly higher OR for proteinuria, compared with the Chinese race (OR of 1.3). Finally, FKD was significantly associated with proteinuria (OR of 1.7), whereas a family history of diabetes mellitus and a family history of hypertension were not. When family histories were analyzed by clustering, isolated FKD remained a significant determinant of proteinuria and the magnitude of the effect was not significantly different from that observed in the presence of a coexisting family history of diabetes mellitus or hypertension. This is the first study to evaluate factors associated with proteinuria in an Asian population. The epidemiologic study of renal disease in this population suggests that risk factors for renal disease might differ significantly among racial groups.

    PMID: 17008283
    In Malaysia, about 4.5% of the Malay and Chinese populations are heterozygous carriers of beta-thalassaemia. The initial identification of rare beta-globin gene mutations by genomic sequencing will allow the development of simpler and cost-effective PCR-based techniques to complement the existing amplification refractory mutation system (ARMS) and gap-PCR used for the identification of beta-thalassaemia mutations.

  18. Serum lipoprotein(A) profiles in a Singaporean population
    Wong MS, Chew WL, Aw TC
    Pathology, 1999 Aug;31(3):225-9.
    PMID: 10503268
    Lipoprotein(a) [Lp(a)] is formed when apolipoprotein(a) is linked to low density lipoprotein (LDL)-cholesterol via a single disulfide bond. It is an independent risk factor for myocardial infarction and raised concentrations are associated with an increased risk of developing coronary artery disease. Singapore has a multi-racial population of 77% Chinese, 14% Malays and 7% Indians. Studies have shown that the Indians have significantly higher standardised mortality ratios (SMR) compared to the Chinese and the Malays. We measured serum Lp(a) concentrations in 803 healthy individuals recruited from the Multiphasic Health Screening Programme, using the Macra Lp(a) sandwich enzyme immunoassay kit (Strategics Diagnostics, Delaware, USA). Lp(a) concentrations were skewed in all three groups. Our population mean was 9.0 mg/dl, with 50th, 75th and 95th percentile values of 10.2, 19.8 and 43.1 mg/dl, respectively, which are lower than values reported from Caucasian populations (15.0, 29.0 and 60.0 mg/dl, respectively). Males had lower Lp(a) concentrations than females (P < 0.05). The Indian group had significantly higher concentrations (median 12.3 mg/dl) compared to their Chinese (median 9.6 mg/dl) and Malay (median 8.4 mg/dl) counterparts (P < 0.05). This could partly account for the higher SMR seen in the Indian population in Singapore. As serum Lp(a) concentrations are method- and population-dependent, we recommend that laboratories determine their own reference ranges by their method to avoid misclassification of the coronary heart disease (CHD) risk of patients.

    Human endothelial nitric oxide synthase (eNOS) is one isoform of the nitric oxide synthases that are responsible for nitric oxide synthesis from L-arginine. The gene encoding eNOS contains a 27-bp VNTR polymorphism in intron 4. We report here for the first time the presence of a novel allele 3, which was absent in all other populations studied to date, in 1.7% each of Singaporean Indians and Malays. We also detected the presence of a novel genotype 3/5 in 3.4% each of Singaporean Indians and Malays. Allele 6, which was absent in Han Chinese from northern China and Taiwan and was also absent in Indians from the Indian subcontinent, was found in 2.1% of Singaporean Chinese and in 0.3% of Singaporean Indians.

    The objective of the study was to determine the proportion of sound HIV knowledge and common misconceptions about HIV among university students. A set of pre tested and validated questionnaire assessing sound HIV knowledge and common misconceptions about HIV was used in this cross sectional study. HIV knowledge was defined as sound when one was able to identify correctly two ways of preventing the sexual transmission of HIV and reject three major misconceptions about HIV. Out of 300 respondents, 298 completed the questionnaire giving a response rate of 99.3%. A total of 40.9% of university students have sound HIV knowledge. The majority of those who lacked sound HIV knowledge were young (60.2%) and female (60.4%). A significant proportion still believed that HIV can be transmitted via social contact (13.8%), by sneezing or coughing (11.4%) and mosquito bites (10.1%). About 6.7% were believed wrongly that HIV can be treated by vaccine and healthy-looking people cannot have HIV.
