    International Journal of Public Health and Clinical Sciences, 2016;3(6):50-64.
    Background: Despite the numerous health education programmes provided to the type 2 diabetes patients worldwide, the outcome of the diabetic management remains a challenge globally. Health literacy plays an important role in determining the outcomes from the diabetes management.
    Materials and Methods: This study was aimed to determine the level of health literacy and its associated factors among type 2 diabetes mellitus patients attending a government health clinic. This study also aimed to determine the association between the associated factors, such as sociodemographic, socioeconomic characteristics, type of treatment, diabetes duration, and knowledge on diabetes and the level of health literacy as well as the predictors of the level of health literacy. This was a cross-sectional study that was conducted from 1st February 2016 to 30th July 2016. A total of 360 participants were randomly selected from a government health clinic through a systematic random sampling method. A validated, self-administered questionnaire incorporating sociodemographic characteristics, socioeconomic characteristics, history of type 2 diabetes, diabetes knowledge and health literacy level was used in this study. Data was analysed using IBM Statistical Package for Social Science Version 22.0. Chi square test, Fisher’s Exact test and simple logistic regression were used to measure the association between the associated factors and health literacy level. Multiple logistic regression analysis was used to analyse the predictors influencing health literacy level among type 2 diabetes mellitus patients.
    Result: The response rate was 80%. Majority of the respondents have limited health literacy level (85.8%). There were significant association between ethnic group and health literacy level (χ2=6.317, P=0.042), level of education and health literacy level (χ2=6.304, P=0.043) and diabetes knowledge score and health literacy level [Odds Ratio (OR)=1.254, 95% Confidence Interval (CI) (1.063,1.479)]. Finally, the significant predictors for adequate health literacy level were the Chinese ethnic group [Adjusted OR (AOR)=4.441, 95% CI (1.472,13.392)] and diabetes knowledge score [AOR=1.238, 95% CI (1.031,1.488)].
    Conclusion: In conclusion, level of health literacy among type 2 diabetes mellitus patients was significantly associated with the ethnic group, level of education and diabetes knowledge score. It can also be concluded that Chinese ethnic group and diabetes knowledge score were the significant predictors for adequate health literacy level among type 2 diabetes mellitus patients.

    Saha N, Ng TB, Tan PY, Wee KP
    Br J Nutr, 1988 Nov;60(3):407-12.
    PMID: 3219311 DOI: 10.1079/bjn19880112
    1. The vitamin A content of human liver tissue was determined in 363 autopsy samples. The sample comprised a total of 181 subjects dying after accidents and 182 dying from coronary heart disease among Singapore ethnic groups of both sexes. 2. The medium vitamin A reserve was 146 mg/kg in accident victims and 141 mg/kg in those who had died of coronary heart disease. Of all the samples 16% contained less than 40 mg/kg, 45% had 100-300 mg/kg, while 9% contained more than 500 mg/kg liver. 3. Among the accident victims, Indians had the lowest median liver vitamin A reserve (118 mg/kg) compared with that in other ethnic groups (137 mg/kg in Chinese, 191 mg/kg in Malays, 155 mg/kg in Caucasians). 4. The ethnic distribution of vitamin A reserve in coronary deaths was similar to that in accident victims. 5. There was no significant difference between the sexes in hepatic vitamin A reserve. 6. The distribution of vitamin A reserve in all the groups was skewed to the right.

  4. Population genetics of coagulation factor XIIIB in three ethnic groups of Singapore
    Saha N, Tay JS, Low PS, Basair JB
    Ann Hum Biol, 1992 5 1;19(3):277-83.
    PMID: 1616285
    The distribution of plasma coagulation factor XXIIB polymorphism was determined by PAG isoelectric focusing and immunoblotting in a group of 670 subjects comprising 375 Chinese, 110 Malays and 185 Indians. The frequencies of FXIIIB*1, FXIIIB*2, and FXIIIB*3 were found to be 0.27, 0.03 and 0.70 in the Chinese; 0.33, 0.05 and 0.64 in the Malays and 0.58, 0.08 and 0.33 in the Indians. The phenotypic distribution of FXIIIB alleles was at Hardy-Weinberg equilibrium in all three populations. A two-dimensional principal-components analysis on the basis of three common alleles at the FXIIIB locus among 19 populations, so far studied, clearly differentiates the Negroid, Mongoloid and Caucasoid populations into three major groups with the exception of Amerindians (Minnesota) and US Blacks showing some Caucasoid influence.

  5. Genetic markers in a Malaysian population: variants of uridine monophosphate kinase (UMPK), phosphoglycolate phosphatase (PGP) and pancreatic amylase (AMY2)
    Zarinah KH, Abdullah F, Tan SG
    Ann Hum Biol, 1984 11 1;11(6):533-6.
    PMID: 6084457
    Three genetic markers, red-cell UMPK, PGP and serum AMY2 were investigated in Malaysians of Malay, Chinese and Indian ancestries using starch-gel and agarose-gel electrophoresis. UMPK was found to be polymorphic in all three races. Variants were observed for PGP in Malays; in Indians it is a polymorphic marker whereas it is monomorphic in Chinese. AMY2 was polymorphic only in Indians. The UMPK1 frequencies in Malays, Chinese and Indians, respectively, are 0.851, 0.880 and 0.942. The PGP1 frequencies are 0.991, 1.000, 0.962, and the AMY1(2) frequencies are 1.000, 1.000 and 0.983.

  6. Penile length of newborns in Singapore
    Lian WB, Lee WR, Ho LY
    J Pediatr Endocrinol Metab, 2000 Jan;13(1):55-62.
    PMID: 10689638
    Micropenis is an important sign in congenital hypopituitarism and various disorders. Documented norms for penile length exist only for babies of Caucasian and Middle-Eastern origin. This study was carried out to establish such norms for Asian newborns. We studied 228 male live births within their first three days of life. Stretched penile lengths were marked off on unmarked wooden spatulas, which were placed vertically along the dorsal aspect of the penis, with one rounded end on the pubic bone. The mean penile length +/- S.D. for the full-term Asian baby was 3.6 +/- 0.4 cm. Race had a significant effect: Chinese 3.5 cm, Malay 3.6 cm and Indian 3.8 cm. Penile length correlated with birth weight and gestational age. Asian babies thus have similar norms to Caucasian babies. An Asian newborn whose penis measures less than 2.6 cm has micropenis and may need prompt investigation for underlying endocrine disorders.

  7. Descriptive epidemiology of nasopharyngeal carcinoma in Peninsular Malaysia
    Prasad U, Rampal L
    Cancer Causes Control, 1992 Mar;3(2):179-82.
    PMID: 1562708 DOI: 10.1007/BF00051659
    Nasopharyngeal carcinoma (NPC) is one of the most common cancers in Malaysia, a country in Southeast Asia with a multiracial population. While hospital-based data on NPC and data from a few states have been reported, a comprehensive study involving every known NPC patient in the whole of Peninsular Malaysia in one particular year had never been done. In the present study, the computed incidence rate was not only adjusted for age, sex, ethnicity, and place of residence, but also direct standardization methods of Rothman and Dever were used to reduce any distortion. The mean age of the 365 new cases of NPC registered in 1988 was 46.8 years (SD +/- 12.2 years). The ages of patients ranged from 10 to 80 years. The incidence in both sexes rose after the age of 20-29 years and reached a plateau between 40 and 49 years. No further rise was exhibited after age 60 years. The Chinese had the highest age-adjusted incidence rates, particularly for the age group 40-49 years, where the incidence rate was 40.1 per 100,000 for males and 14.9 for females. The average age-adjusted male/female ratio was 2.8:1. Age-adjusted incidence varied by place of residence. The pattern that emerged from the data indicated the possibility of interaction between genetic susceptibility and environmental cofactors in the etiology of NPC.

    Diabetes requires dedicated self-management to be able to achieve good control and outcome as this is a lifelong condition. The internet offers an amazing wealth of health information which may influence diabetes self-management. The aim of this study was to determine the prevalence of online health information seeking among people with diabetes and its associated factors. About 380 participants answered the online health information seeking questionnaire developed from literature search and expert panel review. Diabetes Self-Management was assessed using the Diabetes Self-Management Questionnaire (DSMQ). The prevalence of online health information seeking among people with diabetes was 38.4%. Common information sought included diabetes treatment (82.9%) lifestyle modification (77.4%) and diabetes prevention (67.3%). A large majority (93.1%) felt that the online information on diabetes was useful. Doctors and printed reading materials were the most common sources of information for diabetes (94.2% & 65.3%). Lower median age (59 years, IQR = 11), having a family member with diabetes, (COR = 1.188) tertiary education (COR = 6.037) and those who are employed (COR = 3.880) have higher odds of seeking online diabetes related health information. However, there was no significant association between online health information seeking and diabetes self-management. Prevalence of online health information seeking among people with diabetes was at an acceptable level. However, it was not associated with optimal diabetic self-management. Doctors and printed information remain as popular sources of information and hence should be maintained.

  10. Fulltext Determinants of Health-Related Quality of Life (HRQoL) in the Multiethnic Singapore Population - A National Cohort Study
    Leow MK, Griva K, Choo R, Wee HL, Thumboo J, Tai ES, et al.
    PLoS One, 2013;8(6):e67138.
    PMID: 23826215 DOI: 10.1371/journal.pone.0067138
    BACKGROUND: HRQoL is an important outcome to guide and promote healthcare. Clinical and socioeconomic factors may influence HRQoL according to ethnicity.

    METHODOLOGY: A multiethnic cross-sectional national cohort (N = 7198) of the Singapore general population consisting of Chinese (N = 4873), Malay (N = 1167) and Indian (N = 1158) adults were evaluated using measures of HRQoL (SF-36 version 2), family functioning, health behaviours and clinical/laboratory assessments. Multiple regression analyses were performed to identify determinants of physical and mental HRQoL in the overall population and their potential differential effects by ethnicity. No a priori hypotheses were formulated so all interaction effects were explored.

    PRINCIPAL FINDINGS: HRQoL levels differed between ethnic groups. Chinese respondents had higher physical HRQoL (PCS) than Indian and Malay participants (p<0.001) whereas mental HRQoL (MCS) was higher in Malay relative to Chinese participants (p<0.001). Regressions models explained 17.1% and 14.6% of variance in PCS and MCS respectively with comorbid burden, income and employment being associated with lower HRQoL. Age and family were associated only with MCS. The effects of gender, stroke and musculoskeletal conditions on PCS varied by ethnicity, suggesting non-uniform patterns of association for Chinese, Malay and Indian individuals.

    CONCLUSIONS: Differences in HRQoL levels and determinants of HRQoL among ethnic groups underscore the need to better or differentially target population segments to promote well-being. More work is needed to explore HRQoL and wellness in relation to ethnicity.

  11. Lessons learnt from the epidemiology of Helicobacter pylori infection in Malaysia: JGHF Marshall and Warren Lecture 2017
    Goh KL
    J Gastroenterol Hepatol, 2018 Jun;33(6):1177-1184.
    PMID: 29498759 DOI: 10.1111/jgh.14131
    The study of Helicobacter pylori in Malaysia has given several important insights into the epidemiology of the infection and pathogenesis of disease. Malaysia has a multiracial Asian population with three major Asian races living together-Malay, Chinese, and Indian. Races remain fairly distinct because of a paucity of interracial marriages. The "Racial Cohort Hypothesis" proposes that the infection occurs within racial groups rather than between. As such, the high prevalence among Indians (> 50%) and Chinese (40-50%) reflects the high prevalence in their countries of origin even though migration had taken place more than two generations before. The Malays have a comparatively low prevalence of about 10-20%. Despite the high prevalence of H. pylori, the Indians have a low gastric cancer incidence of less than 10 per 100 000 per year. This is in contrast to the Chinese who has an incidence in excess of 20 per 100 000 per year. We have called this the "Indian Enigma." The reason for this enigma is unclear and is the result of interaction between bacterial virulence factors, host susceptibility, and environmental factors. Phylogenetically, Chinese bacterial strains are distinct from Indians and Malays and are predominantly hpEastAsia/hsp EAsia. CagA EPIYA motifs among Chinese belong predominantly to the more virulent ABD motif. There is no clear distinguishing profile among host genetic factors. Environmental factors particularly diet may play an important role. Indians consume chilies and curries, which may be gastro protective, whereas Chinese consume more preserved and salted foods, which are thought to be carcinogenic.

  13. Apolipoprotein E genotyping in the Malay, Chinese and Indian ethnic groups in Malaysia - a study on the distribution of the different apoE alleles and genotypes
    Seet WT, Mary Anne TJ, Yen TS
    Clin Chim Acta, 2004 Feb;340(1-2):201-5.
    PMID: 14734213 DOI: 10.1016/j.cccn.2003.11.001
    BACKGROUND: Apolipoprotein E (apoE) is encoded by a polymorphic gene located on chromosome 19. The three common apoE alleles are epsilon2, epsilon3 and epsilon4. We studied the frequencies of the apoE alleles and genotypes in the three ethnic groups-Malay, Chinese and Indian-in Malaysia using DNA amplification followed by agarose gel electrophoresis.
    METHODS: EDTA blood was collected and DNA was extracted using proteinase K-SDS digestion and purified by phenol-chloroform extraction. The apoE gene sequence was amplified using the PCR and apoE genotyping was performed by restriction enzyme digestion with HhaI.
    RESULTS: Genotyping of the apoE gene produces six genotypes-E2/E2, E2/E3, E3/E3, E2/E4, E3/E4 and E4/E4. The most common apoE genotype in the Malays, Chinese and Indians studied was E3/E3, thus the most common apoE allele was epsilon3. The three common apoE genotypes were E3/E3 followed by E3/E4 and E2/E3, except in the Indians where E2/E3 was not detected. The three apoE alleles were confirmed in the Malays, Chinese and Indians except for the epsilon2 allele which was absent in the Indians.
    CONCLUSION: The combined frequency of the apoE alleles in the Malays, Chinese and Indians was 0.058, 0.829 and 0.114 for epsilon2, epsilon3 and epsilon4, respectively.

    PMID: 8853255
    Primary biliary cirrhosis (PBC) is uncommonly described from Asia and it is an extremely rare cause of chronic liver disease in India. Six first generation migrant Asian patients with PBC were seen at the Liver Unit, Queen Elizabeth Hospital, Birmingham during the period 1982-94. All were women and their ages at presentation ranged from 31 to 63 (median 40) years. All were symptomatic for a median of 6 months prior to referral to the unit for transplantation. Itching with or without jaundice was a common presenting feature. Diagnosis was based on raised serum IgM levels, presence of antimitochondrial antibody (titres 100-400) and diagnostic histology. Only one patients had an associated autoimmune disease (coeliac disease). Serum bilirubin level was above 100 mumol/l at the time of presentation in four patients. Four of these patients with end-stage PBC are first generation migrants from south Asia, who have been resident in the West Midlands for the past 10 to 34 years. The total south Asian population of the West Midlands is 276,754; thus, from these four patients alone the estimated prevalence of PBC in the migrant south Asian population is at least 14 per million. However, such data cannot be used to give any accurate assessment of prevalence, for which a population screening programme is required. A higher incidence in the migrant population than in their countries of origin is compatible with an environmental aetiology.

    Singapore Med J, 1995 Jun;36(3):288-91.
    PMID: 8553095
    The aim of this study was to establish the lymphocyte subset reference ranges in a defined Malaysian population as well as to determine inter-racial differences for these values. Normal blood obtained from 152 subjects (55.9% Malay, 26.3% Chinese and 17.7% Indian) was immunophenotyped. Results obtained (expressed as mean +/- SD %), absolute count (x 10(6) cells/mm3) were as follows: CD3:66.5 +/- 8.6%, 2,066; CD4:33.2 +/- 8.5%, 1,028; CD831.6 +/- 8.9%, 982; CD19:12.0 +/- 0%, 5,374, and CD56+CD16:20.9 +/- 9%, 1,638. There were no significant differences between the percent lymphocyte subsets of the three racial groups. However, the absolute number of CD4 cells and CD19 cells in Chinese was significantly lower (p < 0.05) compared to the Indian and the Indian and Malay groups respectively. Comparison of our results with other reports showed that the percentage of Natural Killer cells in this population is higher than that reported for Caucasian population.

  16. Fulltext Cervical screening in elderly women in Singapore
    Ho T, Yoong T
    Singapore Med J, 1996 Feb;37(1):61-5.
    PMID: 8783916
    The study was conducted to determine the pick-up rate of abnormal cervical smears and the prevalence rate of cervical cancer in women aged 60 years and above and the demographic characteristics of the women screened. The pick-up rate of abnormal cervical smears was 1.65%. The prevalence rate for cervical intraepithelial neoplasia and frank carcinoma was 6.4 and 5.0 per thousand women screened respectively. The study group comprised 89.7% Chinese, 4.7% Malays, 3.6% Indians and 2.0% Others. The pick-up rate of abnormal smears was 1.9% in the Chinese and 1.3% in the Indians. There were no abnormal smears in the Malays and Others. The results demonstrate the importance of a routine cervical cancer screening programme among elderly women aged 60 years and above in Singapore.

  18. Fulltext Education and myopia in 110,236 young Singaporean males
    Au Eong KG, Tay TH, Lim MK
    Singapore Med J, 1993 Dec;34(6):489-92.
    PMID: 8153707
    Computerised data of 110,236 Singaporean males aged 15 to 25 (mean 17.75) years who underwent compulsory medical examination from April 1987 to January 1992 were used to estimate the prevalence and severity of myopia among young Chinese, Malay, Indian and Eurasian Singaporean males with different educational levels. The prevalence and severity of myopia amongst the groups with different educational levels were compared. These groups were fairly well-matched for important known confounding factors such as age, sex, race and degree of urbanisation of place of residence. Our data showed a positive association between educational attainment and both the prevalence and severity of myopia. Both the prevalence of myopia and the proportion of myopes with severe myopia were in general higher among those with more years of formal education.

  19. Fulltext Factors influencing pulse oximetry as compared to functional arterial saturation in multi-ethnic Singapore
    Lee KH, Hui KP, Tan WC, Lim TK
    Singapore Med J, 1993 Oct;34(5):385-7.
    PMID: 8153680
    Noninvasive oximetry provides continuous monitoring of arterial oxygen saturation and hence, early detection of hypoxia. This has proved to be a useful adjunct to patients' safety, and is considered indispensable in certain settings. However, errors may be present in the pulse oximeter estimation (SpO2) of arterial oxygen saturation (SaO2), which may be due to various parameters. We have studied a multi-ethnic population where the skin pigmentation is different, and also under different conditions comparing SpO2 with SaO2. Our results showed that SpO2 estimation of SaO2 amongst the three racial groups (Chinese, Malays, and Indians) varied significantly (ANOVA, p < 0.05). The over-estimation was more pronounced by hypoxic conditions and jaundice. Haemoglobin and systolic blood pressure did not affect the difference between SpO2 and SaO2.

    This is a report on 11 cases of Juvenile Myoclonic Epilepsy (JME) from the University Hospital, Kuala Lumpur, all of whom were diagnosed in the last one and a half years. This genetic syndrome is seen in all the three main racial groups: Chinese, Malays and Indians. It accounts for 2% of the epilepsy patients seen at the neurology clinic. Lack of awareness is the main hindrance to diagnosis.
