Fulltext Dietary fat, fat subtypes and hepatocellular carcinoma in a large European cohort

Duarte-Salles T, Fedirko V, Stepien M, Aleksandrova K, Bamia C, Lagiou P, et al.

Int J Cancer, 2015 Dec 01;137(11):2715-28.
PMID: 26081477 DOI: 10.1002/ijc.29643

The role of amount and type of dietary fat consumption in the etiology of hepatocellular carcinoma (HCC) is poorly understood, despite suggestive biological plausibility. The associations of total fat, fat subtypes and fat sources with HCC incidence were investigated in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, which includes 191 incident HCC cases diagnosed between 1992 and 2010. Diet was assessed by country-specific, validated dietary questionnaires. A single 24-hr diet recall from a cohort subsample was used for measurement error calibration. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated from Cox proportional hazard models. Hepatitis B and C viruses (HBV/HCV) status and biomarkers of liver function were assessed separately in a nested case-control subset with available blood samples (HCC = 122). In multivariable calibrated models, there was a statistically significant inverse association between total fat intake and risk of HCC (per 10 g/day, HR = 0.80, 95% CI: 0.65-0.99), which was mainly driven by monounsaturated fats (per 5 g/day, HR = 0.71, 95% CI: 0.55-0.92) rather than polyunsaturated fats (per 5 g/day, HR = 0.92, 95% CI: 0.68-1.25). There was no association between saturated fats (HR = 1.08, 95% CI: 0.88-1.34) and HCC risk. The ratio of polyunsaturated/monounsaturated fats to saturated fats was not significantly associated with HCC risk (per 0.2 point, HR = 0.86, 95% CI: 0.73-1.01). Restriction of analyses to HBV/HCV free participants or adjustment for liver function did not substantially alter the findings. In this large prospective European cohort, higher consumption of monounsaturated fats is associated with lower HCC risk.

Fulltext Homozygous Wildtype of XPD K751Q Polymorphism Is Associated with Increased Risk of Nasopharyngeal Carcinoma in Malaysian Population

Lye MS, Visuvanathan S, Chong PP, Yap YY, Lim CC, Ban EZ

PLoS One, 2015;10(6):e0130530.
PMID: 26086338 DOI: 10.1371/journal.pone.0130530

The xeroderma pigmentosum group D (XPD) gene encodes a DNA helicase, an important component in transcription factor IIH (TFIIH) complex. XPD helicase plays a pivotal role in unwinding DNA at the damaged region during nucleotide excision repair (NER) mechanism. Dysfunctional XPD helicase protein from polymorphic diversity may contribute to increased risk of developing cancers. This study aims to determine the association between XPD K751Q polymorphism (rs13181) and risk of nasopharyngeal carcinoma (NPC) in the Malaysian population. In this hospital-based matched case-control study, 356 controls were matched by age, gender and ethnicity to 356 cases. RFLP-PCR was used to genotype the XPD K751Q polymorphism. A significant association was observed between XPD K751Q polymorphism and the risk of NPC using conditional logistic regression. Subjects with homozygous Lys/Lys (wildtype) genotype have 1.58 times higher odds of developing NPC compared to subjects with recessive combination of heterozygous Lys/Gln and homozygous Gln/Gln genotypes (OR = 1.58, 95% CI = 1.05-2.38 p = 0.028) adjusted for cigarette smoking, alcohol and salted fish consumption. Our data suggests that Lys/Lys (wildtype) of XPD K751Q contributes to increased risk of NPC in the Malaysian population.

Increased psychosocial risk, depression and reduced quality of life living with autosomal dominant polycystic kidney disease

Simms RJ, Thong KM, Dworschak GC, Ong AC

Nephrol Dial Transplant, 2016 07;31(7):1130-40.
PMID: 26268712 DOI: 10.1093/ndt/gfv299

BACKGROUND: The psychosocial impact of living with autosomal dominant polycystic kidney disease (ADPKD) is poorly understood. In this study, we assessed the overall quality of life (QOL), mood, perceived social support and psychosocial risk of having a diagnosis of ADPKD in a patient cohort from a major UK nephrology centre serving a large catchment population.
METHODS: A postal questionnaire was sent to 349 patients registered at the Sheffield Kidney Institute with chronic kidney disease but not on renal replacement therapy (RRT). The questionnaire incorporated three validated forms: kidney disease quality-of-life short form (KDQOL SF1.3) to assess QOL; nine-item patient health questionnaire (PHQ9) to screen for depression; multidimensional scale of perceived social support (MSPSS) to evaluate perceived social support; as well as a novel genetic psychosocial risk instrument (GPRI-ADPKD) designed to study the specific psychosocial impact of coping with a diagnosis of ADPKD.
RESULTS: The overall response rate was 53%. Patients with a lower estimated glomerular filtration rate (<30 mL/min) or larger kidneys (mean length on ultrasound ≥17 cm) reported reduced QOL and increased psychosocial risk. Clinically significant depression was reported in 22% and 62% felt guilty about passing ADPKD on to their children. In multivariate analysis, female gender was associated with overall poorer psychosocial well-being, whereas increasing age, lower kidney function, larger kidneys and loss of a first degree relative from ADPKD were additional risk factors for QOL, depression or psychosocial risk, respectively.
CONCLUSIONS: Our results reveal a significantly poorer QOL and increasing psychosocial risk with markers of disease progression in patients, particularly women, with ADPKD prior to starting RRT. The future management strategy of ADPKD should address these issues and provide for better individual and family support throughout the patient journey.

Fulltext Psychosocial factors and obesity in 17 high-, middle- and low-income countries: the Prospective Urban Rural Epidemiologic study

Rosengren A, Teo K, Rangarajan S, Kabali C, Khumalo I, Kutty VR, et al.

Int J Obes (Lond), 2015 Aug;39(8):1217-23.
PMID: 25869608 DOI: 10.1038/ijo.2015.48

Psychosocial stress has been proposed to contribute to obesity, particularly abdominal, or central obesity, through chronic activation of the neuroendocrine systems. However, these putative relationships are complex and dependent on country and cultural context. We investigated the association between psychosocial factors and general and abdominal obesity in the Prospective Urban Rural Epidemiologic study.

Fulltext Prediction of cardiovascular disease risk among low-income urban dwellers in metropolitan Kuala Lumpur, Malaysia

Su TT, Amiri M, Mohd Hairi F, Thangiah N, Bulgiba A, Majid HA

Biomed Res Int, 2015;2015:516984.
PMID: 25821810 DOI: 10.1155/2015/516984

We aimed to predict the ten-year cardiovascular disease (CVD) risk among low-income urban dwellers of metropolitan Malaysia. Participants were selected from a cross-sectional survey conducted in Kuala Lumpur. To assess the 10-year CVD risk, we employed the Framingham risk scoring (FRS) models. Significant determinants of the ten-year CVD risk were identified using General Linear Model (GLM). Altogether 882 adults (≥30 years old with no CVD history) were randomly selected. The classic FRS model (figures in parentheses are from the modified model) revealed that 20.5% (21.8%) and 38.46% (38.9%) of respondents were at high and moderate risk of CVD. The GLM models identified the importance of education, occupation, and marital status in predicting the future CVD risk. Our study indicated that one out of five low-income urban dwellers has high chance of having CVD within ten years. Health care expenditure, other illness related costs and loss of productivity due to CVD would worsen the current situation of low-income urban population. As such, the public health professionals and policy makers should establish substantial effort to formulate the public health policy and community-based intervention to minimize the upcoming possible high mortality and morbidity due to CVD among the low-income urban dwellers.

The discriminative ability of waist circumference, body mass index and waist-to-hip ratio in identifying metabolic syndrome: Variations by age, sex and race

Kee CC, Mohd Ghazali S, Lim KH, Subenthiran S, Teh CH, Lim KK, et al.

Diabetes Metab Syndr, 2015 Apr-Jun;9(2):74-8.
PMID: 25819369 DOI: 10.1016/j.dsx.2015.02.006

OBJECTIVES: Many studies have suggested that there is variation in the capabilities of BMI, WC and WHR in predicting cardiometabolic risk and that it might be confounded by gender, ethnicity and age group. The objective of this study is to examine the discriminative abilities of body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR) to predict two or more non-adipose components of the metabolic syndrome (high blood pressure, hypertriglyceridemia, low high density lipoprotein-cholesterol and high fasting plasma glucose) among the adult Malaysian population by gender, age group and ethnicity.
METHODS: Data from 2572 respondents (1044 men and 1528 women) aged 25-64 years who participated in the Non Communicable Disease Surveillance 2005/2006, a population-based cross sectional study, were analysed. Participants' socio-demographic details, anthropometric indices (BMI, WC and WHR), blood pressure, fasting lipid profile and fasting glucose level were assessed. Receiver operating characteristics curves analysis was used to evaluate the ability of each anthropometric index to discriminate MetS cases from non-MetS cases based on the area under the curve.
RESULTS: Overall, WC had better discriminative ability than WHR for women but did not perform significantly better than BMI in both sexes, whereas BMI was better than WHR in women only. Waist circumference was a better discriminator of MetS compared to WHR in Malay men and women. Waist circumference and BMI performed better than WHR in Chinese women, men aged 25-34 years and women aged 35-44 years.
CONCLUSIONS: The discriminative ability of BMI and WC is better than WHR for predicting two or more non-adipose components of MetS. Therefore, either BMI or WC measurements are recommended in screening for metabolic syndrome in routine clinical practice in the effort to combat cardiovascular disease and type II diabetes mellitus.

Workstyle and Musculoskeletal Discomfort (MSD): Exploring the Influence of Work Culture in Malaysia

Maakip I, Keegel T, Oakman J

J Occup Rehabil, 2015 Dec;25(4):696-706.
PMID: 25808991 DOI: 10.1007/s10926-015-9577-2

PURPOSE: Workstyle can be defined as an individual pattern of cognitions, behaviours and physiological reactivity that can occur while performing job tasks. Workstyle has been associated with the development of musculoskeletal disorders (MSDs) amongst office workers in developed countries. However, little is known about the contribution of workstyle on MSDs in developing countries such as Malaysia. The objective of this cross-sectional study was to examine the relationship between workstyle and musculoskeletal discomfort in a sample of office workers in Malaysia.

METHODS: Office workers (N = 417; response rate 65.5 %) from four organisations completed a survey measuring physical and psychosocial hazards, job satisfaction, work-life balance, workstyle, and MSD discomfort levels. Hierarchical regression analyses were undertaken to examine predictors associated with self-reported musculoskeletal discomfort, and more specifically the relationship between workstyle and MSD discomfort.

RESULTS: Musculoskeletal discomfort was significantly associated with working through pain, mental health, physical demands, gender and work-life balance (R (2) = 50.2, adjusted R (2) = 0.48; F (13, 324) = 25.09, p = 0.001). Working through pain is the strongest risk factor associated with MSD discomfort (ß = 0.49, p = 0.001) compared to other potential risk factors.

CONCLUSIONS: Working through pain is influenced by work, social culture and religious beliefs. Workplace MSDs interventions that focus on the impact of physical and psychosocial hazards with emphasis on addressing adverse workstyles should take into account aspects related to work and social culture of the target population. Changes are recommended at both employee and management levels such as better communications and understanding concerning workplace problems with regards to minimizing MSDs at work.

Sudden maternal deaths in Malaysia: a case report

Jegasothy R

J Obstet Gynaecol Res, 2002 Aug;28(4):186-93.
PMID: 12452259

We report on a retrospective study of maternal deaths in Malaysia that occurred within 24 hours of delivery, abortion or operative termination of the pregnancy (defined as sudden deaths) in the years 1995-1996. There were 131 sudden maternal deaths (20.6% of all maternal deaths); postpartum hemorrhage, obstetric embolisms, trauma and hypertensive disorders of pregnancy were the main causes. There was a disproportionately increased risk of sudden maternal deaths in the Chinese and the 'other bumiputra' racial groups. The proportion of mothers who had no obstetric risk factors in the pregnancy that led to death was 16.8%. Fourteen mothers died in transit Twenty mothers died after a cesarean section. The findings of this review emphasize the fact that caregivers in obstetrics need to be forever vigilant. All maternity staff need to be well trained in emergency care and there needs to be quick referral to centers that can provide expertise in handling these emergencies.

Fulltext Review of the trends and causes of food borne outbreaks in Malaysia from 1988 to 1997

Meftahuddin T

Med J Malaysia, 2002 Mar;57(1):70-9.
PMID: 14569721 MyJurnal

This paper examines the trend and possible contributing factors for the occurrence of the food borne diseases outbreaks in Malaysia. These diseases mainly are cholera, typhoid fever, hepatitis A, dysentery and food poisoning. The outbreaks still occur sporadically in certain high risk areas throughout the country. The incidence rate of all the other three major food borne diseases steadily declined from the year 1988 to 1997 except for food poisoning and cholera. Statistic of food poisoning from the year 1996 to 1997 showed that 66.5% of the outbreak occurred in schools whereas only 0.4% originated from the contaminated food sold at various public food outlets. The school age group is always more affected than the general population. Amongst the contributing factors identified are related to unhygienic food handling practices followed by inadequate safe water supply and poor environmental sanitation. A multisectoral approach between Ministry of Health and other government agencies or private agents needs to be undertaken in the management of the food borne diseases in order to curb the incidences of food borne diseases in Malaysia.

Age, sex, haemoglobin level, and white cell count at diagnosis are important prognostic factors in children with acute lymphoblastic leukemia treated with BFM-type protocol

Ng SM, Lin HP, Ariffin WA, Zainab AK, Lam SK, Chan LL

J Trop Pediatr, 2000 Dec;46(6):338-43.
PMID: 11191144

The presenting features and treatment outcome for 575 Malaysian children (< or = 12 years of age) with newly diagnosed acute lymphoblastic leukemia (ALL), admitted to the University Hospital, Kuala Lumpur, Malaysia between 1 January 1980 and 30 May 1995 were evaluated to determine their prognostic significance. Two-year overall survival was achieved in 67 per cent of all patients and 55 per cent of patients were relapse-free at 2 years. All except 10 patients, with identified French-American-British L3 morphology were treated with the modified Berlin-Frankfurt-Munster 78 treatment protocol. Univariate analyses of failure rate conferred age, sex, white cell count and hemoglobin level as potentially significant prognostic factors. All four presenting features retained their prognostic strength in a multivariate analysis. Race, platelet count, morphological subtype, liver/spleen size, lymphadenopathy, central nervous system and mediastinal mass involvement did not show any significant effect on treatment outcome. The 2-year survival rate was significantly different with regard to age, white cell count and hemoglobin level. However, sex was not significantly related to overall survival. These prognostic factors may have implications on future stratification of risk-adjusted initial treatment in the management of childhood ALL. Our analysis of Malaysian children is similar to what could be predicted based on previous studies in other populations.

Fulltext The nutritional status of children in resettlement villages in Kelantan

Zulkifli A, Khairul Anuar A, Atiya AS

Southeast Asian J. Trop. Med. Public Health, 1999 Mar;30(1):122-8.
PMID: 10695800

A cross-sectional survey of the nutritional status of children aged 1-10 years old from the Kuala Betis resettlement villages was carried out. A total of 620 children were examined, of which 329 were preschool children and 291 were schoolchildren. The age was determined and anthropometric measurements such as weight, height and MUAC were taken. The nutritional status was assessed by looking at the distributions of the z-scores of weight-for-age (WAZ), height-for-age (HAZ) and weight-for-height (WHZ) in relation to the growth charts of the National Center for Health Statistics reference population. It was found that the nutritional status of the Orang Asli children was poor, with a prevalence of 33.7-65.3% underweight, 55.3-74.4% stunting and 4.4-29.7% wasting based on the NCHS reference values. The prevalence of malnutrition among the Malay children was lower, underweight--7.3-34.1%, stunting--9.8-34.1% and wasting--1.7-17.1%. The nutritional status of the Orang Asli children were poorer compared to the Malay children. More preschool Orang Asli children were stunted compared to the Orang Asli schoolchildren. This may be due to the poor economic base of the Orang Asli community during the transformation period after resettlement. A comprehensive primary health care program is essential, especially targeting the preschool Orang Asli children in these resettlement villages.

Yusoff NM, Abdullah WZ, Ghazali S, Othman MS, Baba AA, Abdullah N, et al.

Aust N Z J Obstet Gynaecol, 2002 May;42(2):164-6.
PMID: 12069143 DOI: 10.1111/j.0004-8666.2002.00164.x

OBJECTIVES: The objectives of this study were to investigate the prevalence of factor V Leiden mutation in Malay women with recurrent spontaneous abortion and to clarify the contribution of the factor V Leiden mutation to recurrent miscarriages in these women.

DESIGN: A prospective case control study between June 1999 and April 2000.

SETTING: Hospital University Science of Malaysia, Kubang Kerian, Kelantan, and Maternal and Child Health Clinic, Pasir Mas, Kelantan, Malaysia.

SAMPLES: A total of 46 Malay women with a history of three or more first or second trimester miscarriages were studied. The control group consisted of 46 parous women without obstetric complications.

METHODS: Diagnosis of factor V Leiden mutation was made by examination of factor V Leiden allele product following Mnl I digestion of factor V Leiden alleles amplified by polymerase chain reaction.

RESULTS: None of the 46 women with recurrent spontaneous abortion carried the mutation. Also, we found no subject carrying the factor V Leiden alleles in the control group.

CONCLUSION: These results suggest that that there is no association between the factor V Leiden mutation and recurrent spontaneous abortion in the Malay population.

Human immunodeficiency virus type 1 subtypes among Malaysian intravenous drug users

Saraswathy TS, Ng KP, Sinniah M

Southeast Asian J. Trop. Med. Public Health, 2000 Jun;31(2):283-6.
PMID: 11127327

The HIV-1 genetic variation in 60 infected Malaysian intravenous drug users (IDU) was studied by comparison of the nucleotide sequences and their predicted amino acid sequences in the V3 loop of the external glycoprotein gp120. In this study, HIV-1 B, C and E subtypes were identified among Malaysian IDU, with HIV-1 B being the predominant subtype (91.7%). HIV-1 C and HIV-1 E were minority subtypes among Malaysian IDU. Analysis of the amino acid alignment of the C2-V3 region of the env gene suggests a genetic relationship between Thai and Malaysian B and E subtype strains. This study serves as a baseline for monitoring HIV-1 genetic diversity and spread in Malaysia.

The role of expressed breastmilk and continuous positive airway pressure as predictors of survival in extremely low birthweight infants

Boo NY, Puah CH, Lye MS

J Trop Pediatr, 2000 Feb;46(1):15-20.
PMID: 10730035

A case-control study was carried out on 152 extremely low birthweight (ELBW, < 1000 g) infants born consecutively in a large Malaysian maternity hospital during a 21-month period to determine the significant predictors associated with survival at discharge. Forty-nine (32.2 per cent) of these infants survived and 103 (67.8 per cent) died. The survivors weighed significantly heavier (mean = 888 g, SD = 99) than infants who died (mean = 763 g, SD = 131; p < 0.0001). They were also of higher gestational age (mean = 28.7 weeks, SD = 2.2) than those who died (mean = 26.7 weeks, SD = 2.5; p < 0.0001). Logistic regression analysis showed that, after controlling for various confounders, only three factors were significantly associated with the survival of these infants. These were: (1) increasing birthweight of the infants (with every gram increase in birthweight, adjusted odds ratio of survival was: 1.009; 95 per cent CI 1.004, 1.015; p = 0.0006); (2) given nasal continuous positive airway pressure for treatment of respiratory distress syndrome (adjusted odds ratio of survival: 4.2; 95 per cent CI 1.2, 14.0; p = 0.02); and (3) given expressed breastmilk (adjusted odds ratio of survival: 57.5; 95 per cent CI: 7, 474; p = 0.0002). Maternal illness, intrapartum problems, ethnicity, gestational age, use of antenatal steroid, modes of delivery, Apgar scores, congenital anomalies, respiratory distress syndrome, persistent ductus arteriosus, septicemia, necrotising enterocolitis, chronic lung disease, oxygen therapy, intermittent positive pressure ventilation, surfactant therapy, and blood transfusion were not significant factors associated with increased survival.

Truck driver fatigue risk assessment and management: a multinational survey

Adams-Guppy J, Guppy A

Ergonomics, 2003 Jun 20;46(8):763-79.
PMID: 12745978 DOI: 10.1080/0014013021000056980

As part of an organizational review of safety, interviews and questionnaire surveys were performed on over 700 commercial goods drivers and their managers within a series of related companies operating across 17 countries. The results examine the reported incidence of fatigue-related problems in drivers and their associations with near miss and accident experience as well as work and organizational factors. Experience of fatigue problems while driving was linked to time of day and rotation of shifts, though most associations were small. There were significant associations found between fatigue experiences and driver and management systems of break taking and route scheduling. The quantitative combined with qualitative information suggested that, where feasible, more flexible approaches to managing the scheduling and sequencing of deliveries assisted drivers in managing their own fatigue problems through appropriate break-taking. The results are interpreted within the overarching principles of risk assessment and risk control.

Risk factors for early death in acute ischemic stroke and intracerebral hemorrhage: A prospective hospital-based study in Asia. Asian Acute Stroke Advisory Panel

Wong KS

Stroke, 1999 Nov;30(11):2326-30.
PMID: 10548666

BACKGROUND AND PURPOSE: In Asia, there has been no international study to investigate the risk factors for early death in patients with ischemic stroke and intracerebral hemorrhage.
METHODS: We conducted a prospective study of consecutive patients with acute stroke who were admitted to 36 participating hospitals in China, India, Indonesia, Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. With the use of a simple identical data sheet, we recorded the demographics and cardiovascular risk factors of each patient. Early death was defined as death on discharge from the acute hospital.
RESULTS: We enrolled 2403 patients with ischemic stroke and 783 patients with intracerebral hemorrhage. Among patients with ischemic stroke, previous use of antiplatelet drugs (adjusted odds ratio [OR] 0.53; 95% confidence interval [CI] 0. 30 to 0.95) and relatively young age group 56 to 75 years (OR 0.65; 95% CI 0.42 to 1.00) were protective factors; atrial fibrillation (OR 2.23; 95% CI 1.40 to 3.57), ischemic heart disease (OR 2.03; 95% CI 1.37 to 3.05), diabetes (OR 1.52; 95% CI 1.04 to 2.22), and ex-smoker status (OR 2.18; 95% CI 1.18 to 4.05) were risk factors for early death. Among patients with intracerebral hemorrhage, hypertension (OR 0.56; 95% CI 0.38 to 0.82) and young age group 56 to 75 years old (OR 0.55; 95% CI 0.34 to 0.87) were associated with lower death rate, whereas diabetes (OR 1.74; 95% CI 1.01 to 2.98) was a risk factor for early death.
CONCLUSIONS: In Asian patients with stroke, previous use of antiplatelet drugs nearly halved the risk of early death in patients with ischemic stroke, whereas atrial fibrillation, ischemic heart disease, diabetes, and ex-smoker status were risk factors for early death. Among patients with intracerebral hemorrhage, diabetes was associated with early death, whereas young age group and hypertension were associated with lower death rates, though no clear explanation for the hypertension association could be discerned from the data available.

Prevalence of diabetes and ethnic differences in cardiovascular risk factors. The 1992 Singapore National Health Survey

Tan CE, Emmanuel SC, Tan BY, Jacob E

Diabetes Care, 1999 Feb;22(2):241-7.
PMID: 10333940 DOI: 10.2337/diacare.22.2.241

OBJECTIVE: The purpose of the 1992 Singapore National Health Survey was to determine the current distribution of major noncommunicable diseases and their risk factors, including the prevalence of diabetes and dyslipidemia, in Singapore.

RESEARCH DESIGN AND METHODS: A combination of disproportionate stratified sampling and systematic sampling were used to select the sample for the survey. The final number of respondents was 3,568, giving a response rate of 72.6%. All subjects fasted for 10 h and were given a 75-g glucose load, except those known to have diabetes. Blood was taken before and 2 h after the glucose load. Diagnosis of diabetes was based on 2-h glucose alone.

RESULTS: The age-standardized prevalence of diabetes in Singapore residents aged 18-69 years was 8.4%, with more than half (58.5%) previously undiagnosed. Prevalence of diabetes was high across all three ethnic groups. The prevalence of impaired glucose tolerance was 16.1%, that of hypertension was 6.5%, and 19.0% were regular smokers. The total cholesterol (mean +/- SD) of nondiabetic Singaporeans was 5.18 +/- 1.02 mmol/l; 47.9% had cholesterol > 5.2 mmol/l, while 15.4% had levels > 6.3 mmol/l. Mean LDL cholesterol was 3.31 +/- 0.89 mmol/l; HDL cholesterol was 1.30 +/- 0.32 mmol/l, and triglyceride was 1.23 +/- 0.82 mmol/l.

CONCLUSIONS: Prevalence of diabetes was high across all three ethnic groups. Ethnic differences in prevalence of diabetes, insulin resistance, central obesity, hypertension, smoking, and lipid profile could explain the differential coronary heart disease rates in the three major ethnic groups in Singapore.
