Objective: This study was conducted to determine prevalence and factors associated with obesity in Selangor, Malaysia. Methods: A population-based cross-sectional study was conducted in all districts of Selangor State. All individuals, 15 years and above in the selected households, were included. A pre-tested structured questionnaire was used to collect the data. Weight was recorded using TANITA model HD-309 and height was measured using SECA Body meter Model 208. Statistical analysis was performed using Stata 8.2 taking into account the complex survey design. Results: The overall mean age of the 2219 respondents was 36.6(95% CI 35.7 – 37.6) years. There was no significant difference in the mean age of the males and females (p=0.697). The majority of the respondents were Malays (52.9%), followed by Chinese (30.9%), Indians (15.4%) and
other races (0.9%). The overall mean BMI was 24.1 kg/m2 (95% CI=23.8- 24.4). The overall prevalence of obesity was 12.2% (95% CI 10.6%, 14.0%). There was no significant difference in the prevalence of obesity in the males compared to females (p>0.05). The prevalence of obesity increased with age up to the ages of 40-59 years and then decreased after 60 years. The highest prevalence of obesity was in the 40-59 years age groups in both sexes. The overall prevalence of obesity was significantly higher amongst the Malays (15.2%) compared to the Indians (11.6%) and Chinese (7.3%). Multivariate logistic regression analysis showed that only age and ethnicity were associated with obesity. Sex and educational level were not associated with obesity.
A case control study of the families of 35 physically abused and neglected children was conducted to examine some of the family characteristics and sociocultural factors which may contribute to physical abuse and neglect. The cases were matched for sex, ethnic group and as far as possible for age with children admitted to the children's hospital for other medical illness. Physically abused children were more likely to come from disrupted, reconstructed or single parent families and these children had separation experiencesfrom their families during early childhoodfor various reasons including periods of family crisis, parental death, financial difficulties, inability to cope with large family size and cultural beliefs and superstition. Social isolation, alcoholism and drug abuse were also shown to be statistically significant amongst these families.
An analysis of perinatal statistics in Peninsular Malaysia from 1980 — 1989 was undertaken. The Perinatal Mortality Rate showed a 42% decrease over the 10 year period. The Perinatal Mortality Rate was higher among the Indian and Malay ethnic groups compared to the Chinese. This was largely contributed by the higher Stillbirth rate in the former 2 ethnic groups. The Indians have the highest rate of low birthweight babies. There is a decline in the rate of low birthweight babies born over the studied decade. The major causes of early neonatal mortality included problems asociated with prematurity, asphyxia neonatorum, septicaemia and congenital anomalies. Further epi-demiological research is required to identify other riskfactors which contribute to this ethnic biased perinatal mortality rates. Besides intensifying and upgrading current multifaceted approaches, interventional strategies need to be directed to the identified high risk groups. (Copied from article).
26 cases of congenital hypothyroidism were diagnosed at the Penang General Hospital from 1979 to 1993. Therewere 19 femalesand7males, thefemaletomaleratiowas2 .7 : 1. All three main ethnic groups were almost equally afflicted (10 Chinese,8Malays,8 Indians). The mean age at diagnosis was 15.8 months (range 21 days — 9 years) and only 11 (42.3%) patients were diagnosed within thefirst three months of life. 19 (73.7%) patients were diagnosed within thefirstyear and 7 (26.3%) after the firstyear. The correct referral diagnosis was made in less than half (n = 11) of the patients, with a mean of 2.3 doctors being consulted prior to the diagnosis. The five most common clinical features were coarse facies (n = 22), dry skin (n = 22), macroglossia (n = 21), lethargy (n = 20) and constipation (n = 19). The develop-ment quotient was appropriate for chronologi-cal age in less than one third (n = 8) of patients while the school performance was at least average in only less than one third (n = 5) of school-goers (n = 16). The mean (SD) T4 at diagnosis was 23.7 (12.2) nmollL while the mean (SD) TSH at diagnosis was 72.7 (37.0) mUIL. In the light of these clinical findings, screening for congenital hypothyroidism with a view to early diagnosis and prompt treatment are strongly recommended.
Helicobacter pylori has been implicated as an aetiologic agent for type B chronic gastritis, peptic ulcer and gastric cancer. It is considered the most common bacterial infection in the world with approximately 50% of the population being infected. The majority of infected individuals are asymptomatic, with some developing gastritis only. However, chronic infection with H. pylori without antibiotic treatment predisposes infected individuals to the development of gastric cancer. The aim of this study is to determine active H. pylori infection among patients with symptoms of dyspepsia using three combinations of diagnostic methods. In this report, we studied 1,376 consecutive patients who underwent upper gastrointestinal endoscopy at Universiti Kebangsaan Malaysia Medical Center (UKMMC) for dyspepsia from the period January 1999 to December 2002. The classification of patient’s diagnosis was assessed by endoscopic and histological examination. The H. pylori status was determined by rapid urease test, histological examination or H. pylori culture. Presence of H. pylori infection was confirmed in 30.8% of patients with dyspepsia. H. pylori infection was more prevalent in older patients and in males compared to females. Patients with severe gastroduodenal diseases were more commonly infected with H. pylori. There was a significant difference in H. pylori prevalence among the different ethnic groups. Indians had the highest infection rate (45.4%), followed by Chinese (36.8%) and the lowest were seen in Malays (18.3%). This finding on determination of active H. pylori infection among patients with dyspepsia is consistent with serological studies that showed racial differences in H. pylori prevalence. However, the pattern of H. pylori infection does not reflect the prevalence of severe gastroduodenal diseases among different ethnic groups.
Background: (13) C – urea breath test (UBT) is sensitive and specific for detection of Helicobacter pylori (H. pylori) infection. Gastric biopsy culture for H. pylori confirms the diagnosis. Here, we analyzed data of all patients who were investigated for H. pylori infection using both tests throughout the year 2005. Materials and Methods : Retrospective data of 377 patients between the ages of 17 – 88 were identified through endoscopy records from January to December 2005. Upper endoscopy, UBT and gastric biopsy culture were performed on all patients simultaneously during each endoscopy session. Patients who had positive UBT and biopsy culture for H. pylori were treated with triple therapy of PPI, amoxicillin and clarithromycin for one week. A repeat of UBT was done at one-month post therapy. Results and Analysis: Twenty-eight patients on the list had no available data on UBT and were omitted from the analysis. Ethnic group Chinese comprised of 45.4% (n=163), followed by Malay, 37.3% (n=134), Indian, 10.6% (n=38) and others, 3.9% (n=14). UBT was positive in 23.7% (n=85)(figure1). H. pylori culture was positive in 19.2% (n=69)(figure1). Sixteen patients with UBT positive had H. pylori culture negative, 18.8% (n=16/85)(figure2). Five patients with H. pylori culture positive had UBT negative, 7.2% (n=5/69)(figure3). Ethnic group Indian had the highest incidence of UBT positive, 47.4% (n=18/38), followed by Others (Sikhs and foreigners) 42.8% (n=6/14), the Chinese 27.6% (n=45/163) and the Malays 11.6% (n= 16/138). UBT positive was the highest in the age group of 50 and above, 64.7% (n=55/85), followed by the age group between 30 to 49, 21.2% (n=18/85) and the age group of 29 and below, 14.5% (n=12/85). Out of the 85 UBT positive patients 91.8% (n=78/85)(figure4) of them responded to the conventional one week of triple therapy (PPI, amoxicillin, clarithromycin) with negative UBT at one-month post therapy compared to only 8.2% (n=7/85)(figure4) who failed with positive UBT at one-month post therapy.
Malaysia is a country consisting of people of Malay, Chinese and Indian ethnic origin and also of some Indonesian and Thai population. In this study of acute pancreatitis, the age group, sex incidence, clinical
features, complications and treatment were compared between different ethnic groups. A total of fifty-four consecutive patients admitted in Sungai Petani Hospital, Kedah, Malaysia with acute pancreatitis from 2002 to 2004 were taken for this study. There were 29 males and 25 females. The 40–60 years age group was more commonly involved. The common factors associated with acute pancreatitis were alcohol intake in males and biliary disease in females. Two females suffered from acute pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP). One of the 54 cases died due to multi-organ failure.
Medical students are future doctors who are trained to treat all kinds of diseases including people living with HIV/AIDS (PLWHA) without prejudice. Teaching basic scientific knowledge and technical skills is no longer adequate for today’s medical students. There is also a need for them to be provided with high personal and professional values. This study examined stigmatizing attitude towards people living with HIV/AIDS (PLWHA) among the medical students in a public medical school. The participants were stratified to preclinical-year (year 1 and year 2) and clinical-year (year 3 and year 4) medical students. Simple random sampling was carried out to select 170 participants from each category of students. Self-administered questionnaires captured socio-demographic data, HIV/AIDS knowledge and stigmatisation attitudes towards PLWHA. Multiple linear regression was used to assess the relationship between ethnic groups and stigmatization attitude. Three hundred and forty participants were recruited. Malay medical students who did not have previous encounter with PLWHA were associated with stigmatizing attitude towards HIV/AIDS patients, whereas clinical-year medical students who had no clinical encounter with PLWHA were more likely to feel uncomfortable with PLWHA. Malay ethnicity and medical students in clinical years who had not encounter a PLWHA were more likely to have stigmatizing attitude towards PLWHA.
The application of PCR technique in genetic screening was demonstrated using the genetic materials from buccal cells of the students in the class. Two factors were taken into consideration when designing the experiments. The DNA region to be amplified should not be associated with any disease state. This is to eliminate any emotional and ethical problems associated with the experiments. In this practical, the presence and absence of a 38 bp sequence in the intron of COLIA2 gene were studied. The students were also shown on how to analyse the presence of homozygous and heterozygous alleles and the genetic variations that might be observed in the different ethnic groups of students. Another factor was the time taken to complete the experiment. Our experience showed that this experiment would take at least six hours to obtain and analyse the results. It is therefore suitable to be used in class teaching.
Misuse of alcohol among adolescents, particularly schoolchildren has become one of the public health concerns in Malaysia due to its serious effects and an increased risk of alcohol related injuries, especially motor vehicle injuries. This is the most common type of youthful fatal injury in Malaysia. However the availability of data on the extent of alcohol abuse particularly among school children in this country is limited. Therefore, we conducted this study with the objectives of identifying the prevalence of alcohol drinking among school children in Kuala Lumpur, factors rekited to alcohol drinking among the adolescents and to assess health status of their parents through the presence of any related alcohol diseases and the habits of alcohol drinking among their parents.
In this baseline study a two stage stratified sampling design was used to recruit 8532 eligible students from the selected secondary schools in Kuala Lumpur. The prevalence of alcohol drinking was 9.0% (771 / 8532) . Significant factors identihed related to alcohol consumption were akoholic father (OR=1.29), akoholic mother (1 .55) ; elder siblings consume alcohol (2 .49) and the Chinese ethnic group (1 .55) . The study revealed that factors which signihcantly contributed to the habit of alcohol drinking were related to whether their parents consumed alcohol or not or either their eMer siblings were ako taking alcohol. Therefore, the, results from this study could be used as a baseline data to describe the level of alcohol consumption among adolescents particularly school children. Ehfective public health interventions that focus on the familial context of adolescents' drinking habits may be developed.
Non-Leisure Time Physical is the main component of physical activity in Malaysia. The aim of this study is to study the associated factors related to Non-Leisure Time Physical (occupational & travel) in Malaysia. This data is from the Third National Health and Morbidity Survey, consisting of 32,575 respondents. It was a cross-sectional study among Malaysian adult, aged 18 years and was conducted using proportional to the size stratified sampling method. Chi square test and logistic regression model were used to analyse the data. The result showed that non-leisure time physical activity (NLTPA) gives more contribution to total physical activity, as compared to leisure time physical activity with percentage of 64.3% and 35.7% respectively. There was a significant association between NLTPA with age (P < 0.001), gender (P < 0.001), ethnicity (P < 0.001), education (P < 0.001), occupation (P < 0.001), income (P < 0.001), marital status (P < 0.001), region (P < 0.001). The main component of physical activity in Malaysia is NLTPA. Promoting NLTPA may have potential to increase physical activity levels in Malaysia.
Study name: National Health and Morbidity Survey (NHMS-2006)
Beta (β)- thalassaemia is a public health problem in Malaysia. The carrier rate is estimated to be 4.5% by micro-mapping studies particularly among Malays who comprise 53.5% of the population in Malaysia. The common diagnostic method in Malaysia for mutation detection is by amplification refractory mutation system (ARMS). It allows single mutation detection in each reaction but is labour intensive and time consuming when many mutations need to be identified. The purpose of this study was to develop a diagnostic tool for effective mutation detection of beta thalassaemia in Malay patients and compare its efficacy with ARMS-PCR, the current method in use. Methods: Reverse dot blot hybridization (RDBH) technique was incorporated in the development of two strip assays [RDBH-Strip M(6) and RDBH-Strip C(6)] to identify common beta thalassaemia mutations in the Malays. The panels of selected mutations were based on the mutation frequencies in Malaysia reported in previous studies. RDBH-Strip M(6) was applied as step 1 and RDBH-Strip C(6) was applied as step 2 for unidentified mutations. The strips were validated with the gold standard method, ARMS- PCR. Results: One hundred and thirty seven Malay patients with 274 alleles were studied. In Step 1 mutation detection, 238 alleles (86.9%) were identified in 119 of patients by RDBH-Strip M(6). Step 2 resulted in a further detection of 20 alleles in another 10 patients by RDBH-Strip C(6). The combination of both strips resulted in the identification of 258 alleles in 129 (94.6%) of 137 Malay patients. The strip assays were 100% sensitive and specific when compared with ARMS-PCR method. Conclusion: Two strip assays utilising the RDBH technique were developed to identify common β-thalassaemia mutations in Malays. The RDBH Strip M(6) identified 86.9% of the mutations and the RDBH-Strip C (6) detected further 7.3% alleles. This two step strategy was found to be rapid and cost effective for the direct diagnosis of β-thalassaemia mutations in the Malays. The remaining unidentified mutations would require DNA sequencing. It can serve as a specific molecular diagnostic tool for effective diagnosis of
β-thalassaemia mutations in this ethnic group.
The objective of the study was to determine the prevalence of hypertension in healthy primary school children. A cross-sectional survey by manual blood pressure measurement of healthy children aged 6-12 years attending a national type school was carried out. Children with previous renal, cardiac and endocrine disorders were excluded. Korotkoff 1 represented the systolic blood pressure (SBP) and Korotkoff 5 was taken as the diastolic blood pressure (DBP). Hypertension was defined as the SBP or DBP above the 95th centile according to age group and sex regardless of ethnicity. A total of 1756 children were studied with 895 boy and 861 girls. The results showed that 109 children (6.2%) were found to have hypertension and the incidence was similar in boys and girls (6.4% vs 6.0%, p = 0.69). Fifty-three (48.6%) children had an elevated SBP and the DBP was elevated in 43 (39.4%) children. Only 12 (12.0%) children had both elevated SBP and DBP. Children found to have hypertension were more likely to be Chinese (p = 0.009) and obese (p = 0.04). In conclusion the overall prevalence of hypertension in children aged 6-12 years based on a single blood pressure measurement was 6.2%. Hypertension was more likely to be found in Chinese children and those who were obese.
A reported practice of live beetle ingestion in Southeast Asia was investigated among urban Chinese in Kuala Lumpur, Malaysia. Results of four casefindings are: (1) this practice may not be confined to West Malaysia, (2) it occurs among Chinese and Malays, (3) the original use of the beetles as an aphrodisiac has been modified to include treatment of a wide variety of ailments and diseases and (4) the practice is relatively uncommon among urban Chinese. It was also found through experimental studies that ingestion of the live beetles (Palembus dermestoides) represented a potential public health hazard in that the beetles were able to serve as a host for the human-infecting tapeworm Hymenolepis diminuta (Sullivan et al., 1977).
The aim of this study is to describe the epidemiological features of HFMD outbreak in the Hulu Langat District in 2000. Until November 2000, a total of 60 cases were reported and the worst ever reported to the previous years. The mean age of patients was 3.9; 5.8 years with majority of the cases aged between 1 to 4 years old (53.8 per 100,000 of population), male gender (8.3 per 100,000 of populations), and were of Chinese (12.2 per 11 100,000 of populations) and Malay ethnicity (7.2 per 100.000 of populations). All cases were uncomplicated cases and were diagnosed clinically. Most of the notified cases were front the government facilities, which are 44 cases (73.3%). Thirty-five (35) cases (58.4%) were treated as outpatient and 25 cases (41.6%) as in patients (p>0,05). Only 7 cases (11.7%) have history of contact with HFMD patients. The notified cases were mainly from the densely populated areas which were Cheras, Kajang and Ampang. No differences were noted between HFMD cases which have been breasfed for less than 6 month or more, and twenty nine (29) cases (48.3 %) had completed the immunization schedule. In conclusion, the recent emergence of HFMD brings a new challenge, which have to be faced in the prevention and surveillance activities of public health problems in the district.

Objective: To evaluate the health-related quality of life (HRQOL) of patients with chronic depression. Methods: The study involved patients with chronic depression being followed-up at an outpatient clinic at a local hospital in Malaysia. HRQOL was assessed using the Sheehan Disability Scale (SDS); while symptom severity was assessed using the Montgomery-Asberg Depression Rating Scale (MADRS). Results: 104 patients of Malay, Chinese and Indian ethnic groups met the selection criteria. Mean total SDS and MADRS scores was 9.36 ± 7.92 and 13.99 ± 11.58 respectively. There were no significant differences of HRQOL scores between the different ethnicities and between males and females. Symptom severity significantly influenced total and component HRQOL scores. Conclusions: The HRQOL of patients with chronic depression was found to be significantly influenced by symptom severity. Data obtained in this study can be used in the design and implementation of therapeutic and preventive interventions.
