The state of lipid control in patients with diabetes in a public health care centre

Wong JS, Tan F, Lee PY

Asia Pac J Public Health, 2007;19(3):16-21.
PMID: 18330400 DOI: 10.1177/101053950701900304

Achieving treatment targets has been difficult in treating diabetic patients. This cross-sectional study describes the lipid profiles of patients with diabetes mellitus at a public primary health care centre in Sarawak, Malaysia. The targets for lipid control were based on the International Diabetes Federation recommendation (2002). 1031 patients (98% Type 2 Diabetes) were studied. Fasting lipid profiles were available in 990 (96%) patients. The mean total cholesterol was 5.3 +/- 1.0 mmol/L, Triglycerides 1.90 +/- 1.26 mmol/L, HDL-C 1.28 +/- 0.33 mmol/L and LDL-C 3.2 +/- 0.9 mmol/L. Overall, 22% of patients achieved the treatment target for LDL-C level < 2.6mmol/L. 67% of patients had HDL-C > 1.1 mmol/L and 42% of patients had a target TG level below 1.5 mmol/L. Of the 40% of patients who received lipid-lowering drug, 17% achieved LDL-C target, 50% had LDL-C 2.6-4.4 mmol/ L and 33% have LDL-C > 4.0 mmol/L. For the remaining 60% not receiving any lipid lowering therapy, 68% had LDL-C between 2.6-4.0 mmol/L and 7% had LDL-C level > 4 mmol/L. Dyslipidemia is still under-treated despite the availability of effective pharmacological agents and the greatly increased risk of cardiovascular diseases in diabetic patients.

Orgasmic dysfunction among women at a primary care setting in Malaysia

Sidi H, Midin M, Puteh SE, Abdullah N

Asia Pac J Public Health, 2008;20(4):298-306.
PMID: 19124324 DOI: 10.1177/1010539508322810

AIM: The aim of this study was to investigate the prevalence of orgasmic dysfunction and the potential risk factors that may be associated with orgasmic dysfunction among women at a primary care setting in Malaysia.
METHODS: A validated questionnaire for sexual function was used to assess orgasmic function. A total of 230 married women aged 18 to 70 years participated in this study. Their sociodemographic and marital profiles were compared between those who had orgasmic dysfunction and those who did not, and the risk factors were examined.
RESULTS: The prevalence of orgasmic dysfunction in the primary care population was 51.9%. Women with orgasmic dysfunction were found to be significantly higher in the following groups: age >45 years, being non-Malay, having lower academic status, married longer, having more children, married to an older husband, and being at menopausal state.
CONCLUSION: Women with infrequent sexual intercourse are less likely to be orgasmic (odds ratio = 0.29, 95% confidence interval = 0.11-0.74).

Risk factors for fragility fracture in Seremban district, Malaysia: a comparison of patients with fragility fracture in the orthopedic ward versus those in the outpatient department

Loh KY, Shong KH, Lan SN, Lo WY, Woon SY

Asia Pac J Public Health, 2008;20(3):251-7.
PMID: 19124319 DOI: 10.1177/1010539508317130

Osteoporosis is a silent disease and becomes clinically significant in the presence of fragility fracture. Identifying risk factors that are associated with osteoporosis in the community is important in reducing the incidence of fragility fracture. The aim of this study is to identify risk factors associated with fragility fracture in the Seremban District of Malaysia. This is a population comparison study between orthopedic ward patients and outpatients attending a community health clinic for 6 months. Epidemiological data and the possible risk factors for osteoporosis were collected by direct interview. This study demonstrates that advancing age, low body weight, smoking, lack of regular exercise, low consumption of calcium containing foods, and using bone depleting drugs (steroids, thyroid hormone, and frusemides) are major risk factors for fragility fracture. Most of these risk factors are modifiable through effective lifestyle intervention.

Why do patients with chronic illnesses fail to keep their appointments? A telephone interview

Zailinawati AH, Ng CJ, Nik-Sherina H

Asia Pac J Public Health, 2006;18(1):10-5.
PMID: 16629433 DOI: 10.1177/10105395060180010301

Missed appointments affect patients' health in addition to reducing practice efficiency. This study explored the rate and reasons of non-attendance among patients with chronic illnesses. It was a cross-sectional descriptive study carried out in a family practice clinic over a one-month period in 2004. Those who failed turn up for scheduled appointments were interviewed by telephone based on a structured questionnaire. Out of 671 patients, the non-attendance rate was 16.7%. Sixty-seven percent of non-attenders were successfully interviewed. Males (p = 0.01), Indians (p = 0.015), patients with coronary artery disease (p = 0.017), multiple diseases (> 4) (p = 0.036) and shorter appointment intervals (p = 0.001) were more likely to default. The main reasons for non-attendance were: forgot the appointment dates (32.9%), not feeling well (12.3%), administrative errors (19.1%) and work or family commitments (8.2%). The majority would prefer a reminder through telephone (71.4%), followed by letters (41.3%). In conclusion, appropriate intervention could be taken based on the reasons identified in this study.

Social support and glycemic control in adult patients with type 2 diabetes mellitus

Chew BH, Khoo EM, Chia YC

Asia Pac J Public Health, 2015 Mar;27(2):NP166-73.
PMID: 22199159 DOI: 10.1177/1010539511431300

INTRODUCTION: The purpose of this study is to examine the prevalence of social support and its association with glycemic control in patients with type 2 diabetes mellitus (T2D) in an urban primary care center within an academic institution. Social support is important in the management of chronic diseases. However, its association with glycemic control has been controversial.
METHODS: This was part of a study examining religiosity in T2D patients. Nonsmoking patients with T2D for at least 3 years and aged 30 years and above were recruited. Social support was measured using The Social Support Survey-Medical Outcomes Study (SS), a self-administered questionnaire; the scores range from 19 to 95, and a high score indicates better social support. Glycemic control was measured using the 3 most recent glycosylated hemoglobin (HbA1c) levels within the past 3 years.
RESULTS: A total of 175 participants completed the SS survey (response rate 79.0%). The mean age was 62.7 (standard deviation [SD] = 10.8) years, and the mean duration of diabetes was 11.74 (SD = 6.7) years. The mean HbA1c level was 8.15 (SD = 1.44). The mean SS score was 68.1. The prevalence of high and low social support were 29.7% and 24.0 %, respectively. A significant correlation was found between SS score and number of social supporters (n = 167). No significant correlation was found between the self-reported number of social supporters or the SS score and the mean HbA1c level.
CONCLUSIONS: Social support was not associated with glycemic control in adult patients with T2D in this primary care setting.

Antibody reactivity with two strains of human herpesvirus-6 in Malaysians

Yadav M, Umamaheswari S, Ablashi D

J Med Virol, 1991 Apr;33(4):236-9.
PMID: 1649908

A total of 234 sera from healthy Malaysians of diverse ethnic origins were tested for antibody to the Z29 and prototype GS strains of HHV-6. The prevalence in the races ranged from 58 to 80% for the GS strain and 49 to 76% for the Z29 strain. The highest prevalence was in Malays with semi-urban cultural lifestyles and lowest was in the indigenous rural tribes (Ibans, Kadazans, Bidayuhs, and Orang Asli). The antibody titres to GS and Z29 virus capsid antigens differed in 11 (4.7%) samples by more than 2 dilutions. In 9 of the 11 sera the titres to GS strain were higher than to the Z29 strain. The differences in the antibody titres between strains of HHV-6 may reflect subtle changes in antigen structure of the virus recognised by some individuals.

Racial differences in fetal morphometry in Singapore

Yeo GS, Chan WB, Lun KC, Lai FM

Ann Acad Med Singap, 1994 May;23(3):371-6.
PMID: 7944253

A systematic collection of fetal morphometric measurements was started seven years ago in 1987 with the prospective entry of data into personal computer-based stations in the Department of Obstetrics and Gynaecology, Singapore General Hospital. A cross-sectional study was done, comparing 2392 Chinese fetuses with 2117 Malay fetuses and 459 Indian fetuses from 18 to 40 weeks. The mean values of the head circumference (HC), abdominal circumference (AC) and femur length (FL) of the 3 ethnic groups were analysed. There were no statistical significant differences in the head circumference and abdominal circumference of Chinese, Malay and Indian fetuses in Singapore. The Chinese and Malay fetal femur length appeared similar but were apparently shorter than the Indian femur length. Nomograms of head circumference, abdominal circumference and femur length were constructed for application to fetuses of all 3 ethnic groups.

Myocardial infarction in Singapore: a nationwide 10-year study of multiethnic differences in incidence and mortality

Tan AT, Emmanuel SC, Tan BY, Teo WS, Chua TS, Tan BH

Ann Acad Med Singap, 2002 Jul;31(4):479-86.
PMID: 12161884

INTRODUCTION AND METHODS: Cardiovascular diseases have progressively increased in importance as a major contributor of morbidity and mortality in Asia. However, many countries in Asia do not have nationwide systematically-collected and standardised data on myocardial infarction (MI). To accurately document the extent of atherosclerotic coronary heart disease in Singapore, a nationwide myocardial infarct registry was established in the mid-1986. Possible myocardial infarct events were identified through daily national lists of cardiac enzymes, hospital discharge codes, mortuary records and the national death registry. Data obtained from clinical history, cardiac enzymes and 12-lead electrocardiogram Minnesota codes were entered into an algorithm based on the WHO MONICA study. Cases identified as "definite" MI were included in the decade's review for this study.
RESULTS: From 1988 to 1997, 13,048 myocardial infarct events were diagnosed with 3367 deaths. There was a 39.1% decline in mortality, with an average decline of 6.5% per year [95% confidence intervals (CI), -3.9% to -9.1%]. However, the decline in incidence was only 20.8% with an average decline of 2.4% per year (95% CI, -6.6% to -1.2%). The highest incidence and mortality rates for both genders were seen in the Indians, followed by the Malays and the Chinese.
CONCLUSION: Over 10 years, from 1988 to 1997, we documented a significant fall in mortality from MI in Singapore. There was a smaller decline in the incidence of infarction. Singapore implemented a National Healthy Lifestyle Programme in 1992 as a 10-year effort. The disparity in the incidence and mortality may suggest that a more dramatic and immediate impact has taken place in mortality through therapeutic programmes; primary preventive programmes would be more difficult to evaluate and have a more gradual impact. Only with continual accurate data collection through the whole country, over a much longer period, can the relative value of preventive and therapeutic programmes in coronary heart disease be assessed.

Disseminated Penicillium marneffei infection: a report of five cases in Singapore

Kurup A, Leo YS, Tan AL, Wong SY

Ann Acad Med Singap, 1999 Jul;28(4):605-9.
PMID: 10561784

Penicillium marneffei has emerged as an important opportunistic pathogen in HIV-infected patients in Southeast Asia. We report the first 5 cases of P. marneffei diagnosed in Singapore. All the patients were HIV-infected and were either Thai nationals or had frequently travelled to Thailand. Fever, weight loss, anaemia and papular skin lesions were common clinical manifestations in our patients, all of whom had the organism isolated from blood. Skin biopsy specimens showed histological evidence of P. marneffei in 2 patients. In 1 patient each, the organism grew in cultures of specimens from bone marrow and respiratory secretions. Amphotericin B therapy followed by itraconazole were used in 3 of our 5 patients and was associated with good clinical response and outcome.

Tan YK, Khoo KL, Low JA, Wong ZW, Theng CT, Ong TH, et al.

Ann Acad Med Singap, 1999 Mar;28(2):214-6.
PMID: 10497669

We studied the relationship between different ethnic groups, obstructive sleep apnoea (OSA) and ischaemic heart disease. Four hundred and thirty-two inpatients from the medical wards were interviewed. Limited overnight sleep studies were done in 129 of those who had habitual snoring, daytime sleepiness based on an Epworth sleepiness scale of 8 or more, or a large neck size of 40 cm or more. There were 315 Chinese (72.9%), 67 Malays (15.5%), 43 Indians (10%) and 3 from other races (1.4%). The prevalence of OSA was 19.7%, 30% and 12% among the Chinese, Malays and Indians, respectively. The prevalence ratio for OSA was 1.52 in Malays using Chinese patients as the baseline (P = 0.07). The median neck circumference was 37 cm in both racial groups. The median body mass index was 22.7 kg/m2 in Chinese compared to 23.6 kg/m2 in Malays. The median apnoea-hypopnoea index was 22.7, 19.0 and 26.9 events/hour among the Chinese, Malays and Indians, respectively. OSA was independently associated with the prevalence of IHD (adjusted prevalence ratio 1.68; 95% CI: 1.15, 2.46; P = 0.009). The prevalence of ischaemic heart disease (IHD) was 31%, 24% and 28% in Chinese, Malays and Indians, respectively. The prevalence ratio for IHD in Malays compared to Chinese was 0.77. After adjusting for OSA, there was an even greater reduction in the risk of IHD (adjusted prevalence ratio 0.70). This suggests that OSA is a confounder in the relationship between race and ischaemic heart disease.

Mortality analyses of the 1990 Singapore population: I. General life tables

Lun KC

Ann Acad Med Singap, 1995 May;24(3):382-92.
PMID: 7574420

General life tables for the 1990 Singapore resident population are given in this paper. Analyses were carried out separately for males and females for all ethnic groups as well as for Chinese, Malays and Indians. Average fractions of the last age interval lived were used to give a more precise derivation of the life table death rates from their corresponding age-specific death rates. The results show that in 1990, Singapore males had achieved a life expectancy at birth of 73.7 years while the females had attained a level of 78.6 years. These levels were comparable to those of many developed countries. Other interesting features include higher differentials in the life expectancies between sexes among the Chinese and the Indians taking over the Malays for second placing in terms of life expectancy at birth for both sexes. As a result, the Indians registered a 12% gain in life expectancy at birth for males for the decade 1980 to 1990, compared to only 7.1% for Chinese and 4.4% for Malays as well as nearly 10% for females compared to only 6.2% for Chinese and 6.3% for Malays. A subsequent paper will highlight the results of multiple-decrement life table analyses which will summarise the mortality of the 1990 Singapore resident population for various component causes of death rather than for all causes combined.

Ischaemic heart disease and its risk factors in Singapore in comparison with other countries

Hughes K, Yeo PP, Lun KC, Sothy SP, Thai AC, Wang KW, et al.

Ann Acad Med Singap, 1989 May;18(3):245-9.
PMID: 2774470

Mortality from ischaemic heart disease in Singapore is now reaching comparability with the West. For the early 1980s, rates for Indians and Malays were higher than in U.S.A. and England and Wales and while those for Chinese were lower they were considerably higher than in Japan. In keeping with this the levels of the major risk factors in Singapore are now comparable to the West. Cigarette smoking in males is virtually the same as in Britain, while the proportion of hypertensives on medication is higher than in the West. The main cause for concern is the current high levels of serum cholesterol in Singapore and strenuous health education efforts are needed to bring about dietary changes.

Obesity in preschool children: an intervention programme in primary health care in Singapore

Ray R, Lim LH, Ling SL

Ann Acad Med Singap, 1994 May;23(3):335-41.
PMID: 7944246

The Programme on Prevention and Management of Obesity in Preschool Children, aged three to six years, was implemented in 17 Primary Health Clinics in November 1991. The study sample comprised 1128 preschool children who qualified to enter the obesity register, using the defined criteria for obesity of 2 standard deviations above the normal weight for height and age. This group was divided into three categories, namely, mildly overweight (120% to below 140%), moderately overweight (140% to below 160%), and severely overweight (above 160%). The severely overweight category was referred to dietitians for follow-up management, while the other two categories were managed by the clinic staff through pre-planned nurse-conducted counselling sessions. In this paper, we analysed the first 1128 preschool children aged three to six years on the Programme with respect to their demographic characteristics; medical conditions; family history of obesity, diabetes, hypertension and ischaemic heart disease; number of siblings and parents' educational and occupational status. The Malay children showed significantly more severe grades of obesity compared to the Chinese and Indian children. A family history of obesity and hypertension among the three groups were significant (P < 0.001). After one year of follow-up with the intervention programme, the following were found: 40.4% (456) of the children improved in their obesity status and 20.2% (228) reached normal status. The severe, moderate and mild categories reduced from 6.3% to 5.9%, 29.3% to 23.2% and 64.4% to 50.7% respectively and was found to be statistically significant (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Preimmunisation hepatitis B screening in Singapore--a viewpoint from private sector clinics

Mah GK, Yeo A

Ann Acad Med Singap, 1990 May;19(3):339-43.
PMID: 2144101

Blood samples from 1,600 persons who sought immunisation against hepatitis B in private clinics in Singapore in 1988-1989 were screened for two viral markers. Of that total, 4.81% were positive for HBsAg and 17.31% had anti-HBs levels greater than 10 mIU/ml, indicating that about 22.12% of the general population would not benefit from immunisation. Preimmunisation screening will identify persons not requiring the hepatitis B vaccine and thus, avoid wastage. When immunisation has already been performed without screening, recall for post-immunisation screening should be considered in order to detect the infectious hepatitis B carriers. Data in this study indicates that at this point in time, it is important to immunise adolescents and adults, in addition to neonates and children.

Mortality from cardiovascular diseases in Chinese, Malays and Indians in Singapore, in comparison with England and Wales, USA and Japan

Hughes K

Ann Acad Med Singap, 1989 Nov;18(6):642-5.
PMID: 2624412

Age-standardised death rates, for ages 35-64 years in both sexes, from ischaemic heart disease, cerebrovascular disease, and hypertensive disease for Chinese, Malays, and Indians in Singapore (1980-84) have been compared with those in England and Wales, USA and Japan (1982). For ischaemic heart disease Indians have the highest mortality, then Malays, with Chinese less than the Western countries but more than Japan. For cerebrovascular disease the Malays have highest mortality, then Indians, then Chinese, followed by Japan, England and Wales, and USA in that order. For hypertensive disease it is again Malays, then Indians, then Chinese, but followed by the different order of USA, England and Wales, and Japan. The differences are discussed in the light of declining trends in mortality from these disease in Singapore over the preceding 25 years. The special problems of ischaemic heart disease in Indians and hypertension and it's sequelae in Malays are highlighted.

Ng CS, Lim LS, Chng KP, Lim P, Cheah JS, Yeo PP, et al.

Ann Acad Med Singap, 1985 Apr;14(2):297-302.
PMID: 4037689

225 women with diabetes in pregnancy were managed by a team of obstetricians, physicians (endocrinologists) and paediatricians from the National University of Singapore. A protocol of management was formulated and followed. The incidence of 1.1% or 1 in 90 pregnancies was found, with significantly higher incidence in Indians and lower in Malays. There were 37 established diabetics and 188 diagnosed during pregnancy. Of these (188), 74 were gestational diabetics. All the women were treated with Insulin and Diet or Diet alone. 177 (79%) were treated with Insulin and Diet. Blood sugar profiles were done for monitoring diabetic control. 72.8% of the women were between para 0 and 1 and 85.2% between the ages of 20 and 34. 72.5% of the women delivered at 38 weeks gestation or later. 48.9% went into spontaneous labour, 32.4% were induced and 18.7% had elective caesarean section. 62.2% of the women had labour of less than 12 hours. The overall caesarean section rate was 41.7%. There were 3 stillbirths and 2 neonatal deaths. The perinatal mortality rate was 2.2%. Thirteen babies had congenital malformations (5.8%). 77.8% of the babies had Apgar score of 7 or more at 5 minutes after delivery. 79.1% of the babies weighed between 2.5 kgm and 3.9 kgm. Pre-eclamptic toxaemia was the commonest complication in pregnancy followed by Urinary Tract Infection and Polyhydramnios. Postpartum complications in the mother were confined to 14 women (6.2%), and wound infection or breakdown was the commonest cause.

The variation of glucose tolerance in a multi racial population

Ch'ng SL, Chandrasekharan N

Ann Acad Med Singap, 1985 Apr;14(2):223-8.
PMID: 4037680

The pattern of plasma and urine sugar changes after 50g glucose load in 1900 Malaysians (522 males and 1378 females) consisting predominantly of Malays, Chinese and Indians were studied. The data were analysed using Statistical Package for Social Sciences (SPSS). The results show bimodal distribution of 120 min. plasma sugar values in the age groups 21 years and above and trimodal distribution in most groups above 40 years. The mean 120 minutes plasma sugar cut-off values for nondiabetics (ND), impaired glucose tolerance (IGT), and diabetics (DM) of 8.4 and 11.1 mmol/l respectively were close to the values recommended by the National Diabetic Data Group (NDDG). Fifty two percent of all subjects showed peaked plasma sugar values at 60 minutes (14% of them had IGT, 12% DM), 25% peaked at 30 minutes (98% of them were ND). The rest showed peaked values at 90 minutes (17%), 120 minutes (4%) and 150 minutes (2%) and from this group forty two percent were DM and 23% had IGT. Reliance on urine sugar qualitative tests could misclassify 7.3% of subjects (predominantly elderly females) with hyperglycaemia of greater than 11 mmol/l. This study shows that in the 50 g glucose tolerance test, the NDDG criteria for ND, IGT, DM is still applicable to the Malaysian population. The sampling time could be reduced to four points at 0, 60, 90, and 120 minutes. Blood analysis is the preferred method for the diagnosis of hyperglycaemia in elderly females.

Cross-cultural adaptation and validation of Singapore Malay and Tamil versions of the EQ-5D

Wee HL, Loke WC, Li SC, Fong KY, Cheung YB, Machin D, et al.

Ann Acad Med Singap, 2007 Jun;36(6):403-8.
PMID: 17597964

INTRODUCTION: The aims of this study were to cross-culturally adapt and evaluate the validity of the Singaporean Malay and Tamil versions of the EQ-5D.
MATERIALS AND METHODS: The EQ- 5D was cross-culturally adapted and translated using an iterative process following standard guidelines. Consenting adult Malay- and Tamil-speaking subjects at a primary care facility in Singapore were interviewed using a questionnaire (including the EQ-5D, a single item assessing global health, the SF-8 and sociodemographic questions) in their respective language versions. Known-groups and convergent construct validity of the EQ-5D was investigated by testing 30 a priori hypotheses per language at attribute and overall levels.
RESULTS: Complete data were obtained for 94 Malay and 78 Indian patients (median age, 54 years and 51 years, respectively). At the attribute level, all 16 hypotheses were fulfilled with several reaching statistical significance (Malay: 4; Tamil: 5). At the overall level, 42 of 44 hypotheses related to the EQ-5D/ EQ-VAS were fulfilled (Malay: 22; Tamil: 20), with 21 reaching statistical significance (Malay: 9; Tamil: 12).
CONCLUSION: In this study among primary care patients, the Singapore Malay and Tamil EQ-5D demonstrated satisfactory known-groups and convergent validity.

Cardiovascular risk factors in non-insulin-dependent diabetics compared to non-diabetic controls: a population-based survey among Asians in Singapore

Hughes K, Choo M, Kuperan P, Ong CN, Aw TC

Atherosclerosis, 1998 Jan;136(1):25-31.
PMID: 9544728

Cardiovascular risk factors were compared between 126 people with non-insulin-dependent diabetes mellitus (NIDDM) and 530 non-diabetics (controls), in a random sample of people (Chinese, Malays, and Asian Indians) aged 40-69 years from the general population of Singapore. Data were adjusted for age and ethnicity. For both genders, people with NIDDM had higher mean body mass indices, waist-hip ratios and abdominal diameters. They also had a higher prevalence of hypertension, higher mean levels of fasting serum triglyceride, slightly lower mean levels of serum high-density-lipoprotein cholesterol, and higher mean levels of plasma plasminogen activator inhibitor-1 and tissue plasminogen activator (antigen). These factors are components of syndrome X (metabolic syndrome) and increase the risk of atherosclerosis and thrombosis. In contrast, there were no important differences for cigarette smoking, serum total and low-density-lipoprotein cholesterol, serum apolipoproteins A1 and B, plasma factor VIIc and plasma prothrombin fragment 1 + 2. Females with NIDDM, but not males, had a higher mean serum fibrinogen level than non-diabetics, which could explain why NIDDM has a greater cardiovascular effect in females than males. Serum lipoprotein(a) concentrations were lower in people with NIDDM. Mean levels of serum ferritin, a pro-oxidant, were higher in people with NIDDM than controls, but there were no important differences for plasma vitamins A, C and E, and serum selenium, which are anti-oxidants.
