    PMID: 3538434
    Sera from 494 non-icteric patients admitted with illnesses other than overt hepatitis into the various hospitals in rural and urban Malaysia were tested for IgG antibody to hepatitis A virus. The overall antibody prevalence rate was 67.0% with rates increasing steadily from childhood 10 years old and under (39.4%) to middle-age and above (96.0%). No significant differences were noted between males (68.4%) and females (65.3%). The highest rate was in the Indians (80.6%), the lowest in the Chinese (55.9%) with Malays occupying intermediate position (70.3%). The rate in the rural patients (74.7%) was higher than that in the urban patients (65.5%) especially in the 21 to 40 year age-group where the rural patients had a rate of 96.7% compared with that in urban patients (61.1%). A comparison of antibody prevalence rates in different countries was made.

    Southeast Asian J Trop Med Public Health, 1986 Jun;17(2):168-71.
    PMID: 3024324
    During 1984-1985, a total of 838 sera obtained from individuals of different age groups, mostly blood donors and those whose sera were received for VDRL tests and other serological investigations. The sera were titrated for complement fixing antibodies against cytomegalovirus (Ad169 strain). Three hundred and fifty two (41%) out of 838 sera showed significant antibody titre. The incidence of this virus infection varied form 26% in the age group of 11-20 years to 59% of those above 50 years of age. Geometric mean titre (GMT) was highest (22) in age groups of 11-20 years and those over 50 years indicating active viral infection in these two age groups. GMT was also significantly higher in females in all age groups except in the age group of 21-30 years and those above 50 years, indicating that active viral infection is more common in females.

    Ng KH, Siar CH, Ramanathan K, Murugasu P, Chelvanayagam PI
    Southeast Asian J Trop Med Public Health, 1985 Dec;16(4):602-6.
    PMID: 3835704
    The prevalence rate of 749 cases of oral squamous cell carcinomas (SCC) recorded between 1978-1984 was studied. Results showed that the Indians formed the dominant group (63.8%) followed by the Malays (19.6%) and Chinese (16.6%). The peak incidences were generally located between the sixth and eighth decades. Only in the Chinese group a male preponderance was noted. In the Indians, the buccal mucosa was the most prevalent site; in the Malays and Chinese males, the gingiva and alveolus; and the Chinese female, the tongue. In all three groups, the well-differentiated SCC was the commonest type and the poorly differentiated least common.

  4. Epidemiology of cancer in Sarawak, East Malaysia
    Dawie Usop AK
    Southeast Asian J Trop Med Public Health, 1985 Dec;16(4):584-90.
    PMID: 3835700
    A descriptive epidemiology of cancer in Sarawak, based on histopathology records in the Central Medical Laboratory, Kuching, Sarawsk, in 1981 and 1982 was presented. There were 8,219 patients from whom biopsies were taken and 485 from whom marrow biopsies were taken. Out of these, 1,326 were reported malignant. Most of the cases were from Kuching. There were slightly more males than females. The Chinese formed the majority of cases followed by the Sea Dayaks and Malays. The most common cancer sites among males were lymph nodes, nasopharynx, skin and stomach, while in the females the most common sites were the breast, cervix and lymph nodes. Among the Chinese the most common cancers were those of the nasopharynx in males, and breast in females. Among the Sea Dayaks, the most common cancers were those of the lymph nodes in males and cervix in females. Among the Malays, skin cancers were relatively common, and among the Land Dayaks nasopharyngeal cancers were common. Most of the patients were in the older age groups. The pattern of cancers has not changed much since 1966 and the findings of the present study are very similar to the series from the Institute of Medical Research, Kuala Lumpur, in 1969 to 1971.

  5. Markers of hepatitis B virus infection in asymptomatic drug abusers in Malaysia
    Mangalam S, Tan DS, Vijayamalar B, Collett D, Fang R
    Southeast Asian J Trop Med Public Health, 1986 Jun;17(2):209-13.
    PMID: 3787308
    Sera from 200 Malaysian male drug abusers were tested for markers of Hepatitis B virus (HBV) infection, viz. HBsAg, HBeAg, anti-HBs and anti-HBc using commercially available enzyme immunoassay (EIA) kits supplied by Abbot Laboratories, Chicago. Of these, 103 (51.5%) were positive for at least one HBV marker, 11 (5.5%) were positive for HBsAg; 4 (2%) for HBeAg, 74 (37%) for anti-HBs and 85 (42.5%) for anti-HBc. The HBsAg carrier rate was roughly the same as the carrier rate in the general population of Malaysia. The majority of drug abusers (95%) have had subclinical, asymptomatic HBV infection. Racially the Malay drug abusers had the highest exposure rate (54.2%). The HBsAg carrier rate was highest in the Chinese drug abusers (15.3%) and lowest in the Indians (0%). The mean age for the HBsAg carriers was found to be 26 years with a mean duration of drug abuse of 72 months. The Malaysian Anti-Narcotics Task Force of the National Security Council reported in the Malay Mail (July 13, 1985) that there were about 106,000 identified drug abusers in Malaysia and that 63% of these were in the 20-29 age groups. It appears from our study that this age group also coincides with the period of high HBsAg carrier rate. Age wise, those less than 21 years old had the highest HBsAg (11%) and HBeAg (5.6%) prevalence rates indicating high infectivity. After the age of 30 years, nearly 50% of the drug abusers appear to be immune with the HBe prevalence of 0%.(ABSTRACT TRUNCATED AT 250 WORDS)

  6. Diarrhoeal problems in Southeast Asia
    Sunoto
    Southeast Asian J Trop Med Public Health, 1982 Sep;13(3):306-18.
    PMID: 7163834
    Diarrhoea up till now is still a major problem in Southeast Asia with high morbidity and mortality, particularly among children under 5 years of age, with the peak in children between 6 - 24 months. In Indonesia, in 1981, it was estimated that there are 60 million episodes with 300,000 - 500,000 deaths. In the Philippines, diarrhoea ranks as a second cause of morbidity (600 per 100,000 in 1974) and second cause of infant mortality (5 per 1,000 in 1974). In Thailand, in 1980, the morbidity rate was 524 per 100,000 and the mortality rate 14 per 100,000. In Malaysia, in 1976, diarrhoea was still ranking number 5 (3.1%) as a cause of total admission and number 9 (2.2%) as a cause of total deaths. In Singapore, diarrhoea still ranks number 3 as a cause of deaths (4% of total deaths). In Bangladesh, the overall attack rates imply a prevalence of 2.0% for the entire population, with the highest for under 5 groups i.e. 4.1%. The diarrhoea episode in rural population is 85.4%, 39% of them are children under 5. The most common enteropathogens found in all countries are rotavirus followed by Enterotoxigenic E. coli, Vibrio spp., Salmonella spp., Shigella spp. and Campylobacter. Malnutrition and decline of giving breast-feeding play an important role in causing high morbidity, besides socio-economic, socio-cultural and poor environmental sanitation.

    PMID: 20578472
    The teaching profession is an occupation at high risk for stress. This research attempted to determine the prevalence of stress and the associated factors contributing to stress among teachers in Malaysia. A cross-sectional study was conducted on 580 secondary school teachers in Kota Bharu District. The instrument used to carry out the study was adopted and modified from the Depression, Anxiety and Stress Scale (DASS 21) and Job Content Questionnaire (JCQ). The questionnaire consisted of two parts: Part I consisting non-job factors (socio-demographic characteristics) and Part II consisting of psychosocial factors contributing to stress. Simple and multiple linear regression analysis were carried out. The prevalence of stress was reported as 34.0%. Seventeen point four percent of teachers experienced mild stress. Age, duration of work and psychological job demands were significantly associated with stress level. This study indicates job-related factors did not contribute much to stress among secondary school teachers. Non-job-related factors should be further studied to determine methods for stress reduction in teachers in Malaysia.

  8. Fulltext Helicobacter pylori infection in peptic ulcer disease: the importance of smoking and ethnicity
    Pillay KV, Htun M, Naing NN, Norsa'adah B
    Southeast Asian J Trop Med Public Health, 2007 Nov;38(6):1102-10.
    PMID: 18613553
    This study was conducted to determine the prevalence of Helicobacter pylori (H. pylori) and its associated factors among patients with peptic ulcer disease in Taiping Hospital. Consecutive peptic ulcer disease patients who had undergone esophagogastro-duodenoscopy were included. The H. pylori status was assessed by the rapid urease test. We excluded those who had active bleeding, a perforated peptic ulcer, severe vomiting, a history of gastric surgery, peptic ulcer disease or renal or liver diseases, carcinoma of the stomach, and recent use of antibiotics or proton pump inhibitors. Socio-demography, H. pylori status, medication history and other relevant clinical data were collected from case notes. A total of 416 subjects were selected, 49.7% were positive and 50.3% were negative for H. pylori infection. There were significant associations between H. pylori and age, ethnicity, smoking status and NSAID usage. However, there were no significant relationships between H. pylori status and gender or type of peptic ulcer. Multiple logistic regression showed that other ethnicities than Malays and smokers had a higher risk of H. pylori. Our prevalence rate was low and the identified risk factors were consistent with previous studies. Ethnic differences may be related to genetic and sociocultural behaviors. Quitting smoking may benefit peptic ulcer patients with H. pylori infection.

    PMID: 19058587
    Growth impairment is commonly seen in children with thalassemia despite regular blood transfusions and desferrioxamine treatments. We investigated the growth velocity of 26 prepubertal patients with beta-thalassemia or HbE-beta thalassemia who were transfusion dependent aged between 2 and 13 years. The prevalence of impaired growth velocity (ie, growth velocity less than the third percentile) amongst the transfusion dependent prepubertal thalassemics was 57.7% compared to 19.2% in the control group. The mean height velocity of the thalassemics was 11.1% less than controls but this difference was not statistically significant (4.23cm/year vs 4.76cm/year, p = 0.08). The mean serum ferritin level of the thalassemics with a height < 3rd percentile was higher compared to those with a height > 3rd percentile (4,567.0 vs 2,271.0, p = 0.01). Our study showed that there was a high prevalence of impaired growth velocity amongst our transfusion dependent prepubertal thalassemics. This highlights the problem of inadequate chelation therapy, and compliance with chelation therapy amongst our patients. This study emphasizes the importance of monitoring growth parameters and optimal iron chelation therapy in these patients.

  10. Prevalence and distribution of soil-transmitted helminthiases among Orang Asli children living in peripheral Selangor, Malaysia
    Al-Mekhlafi MS, Azlin M, Nor Aini U, Shaikh A, Sa'iah A, Fatmah MS, et al.
    Southeast Asian J Trop Med Public Health, 2006 Jan;37(1):40-7.
    PMID: 16771211
    Soil-transmitted helminthiases are a public health problem in rural communities. A cross-sectional study of the prevalence and distribution of Ascaris lumbricoides, Trichuris trichiura and hookworm was conducted in 281 Orang Asli children (aborigines) aged between 2 and 15 years, from 8 Orang Asli villages in Selangor, Malaysia. All the children were infected with soil-transmitted helminthes, with 26.3% of the children infected either with A. lumbricoides, T. trichiura or hookworm and 72.6% having mixed infection. The overall prevalences of A. lumbricoides, T. trichiura and hookworm were 61.9, 98.2 and 37.0%, respectively. Approximately 19.0, 26.0 and 3.0% of the children had severe infection of ascariasis, trichuriasis and hookworm infection, respectively. The prevalences and mean egg per gram (epg) counts for A. lumbricoides and T. trichiura were not significantly dependent on age, therefore age-dependent convexity was not seen in this study. However, the results of this study reveal an age-dependent prevalence and mean epg count in children with hookworm infection. We conclude that ascariasis, trichuriasis and hookworm infection are still prevalent and therefore a public health concern in Orang Asli communities. Severe ascariasis and trichuriasis may lead to other health and medical problems.

  11. Fulltext Enterobius vermicularis infection among children aged 1-8 years in a rural area in Malaysia
    Norhayati M, Hayati MI, Oothuman P, Azizi O, Fatmah MS, Ismail G, et al.
    Southeast Asian J Trop Med Public Health, 1994 Sep;25(3):494-7.
    PMID: 7777914
    The infection rate and relationship of enterobiasis with socio-economic status were determined in children aged 1-8 years, living in a rural area in Malaysia. Of the 178 subjects 40.4% were infected with Enterobius vermicularis. The distribution of enterobiasis among these children were analyzed in relation to age groups and sex. The rate of infection was significantly higher in older children (5-7 years). The association of enterobiasis with other factors studied such as number of persons per house, household income per months and mother's employment status were not significant. The sensitivity of three successive days anal swabs compared to a single swab was found to be statistically significant.

  12. Fulltext Review of toxoplasmosis in Malaysia
    Yahaya N
    Southeast Asian J Trop Med Public Health, 1991 Dec;22 Suppl:102-6.
    PMID: 1822863
    Various studies on toxoplasmosis in Malaysia have shown that specific antibodies to Toxoplasma gondii are common among Malaysians. Among the ethnic groups, the Malays have the highest prevalence rate followed by Indians, Orang Aslis (aborigines) and Chinese. Antibody is acquired early in life and increases with age. There is no significant difference in the prevalence rate between males and females. The disease is apparently more prevalent among rural dwellers and those in the lower socioeconomic group. It appears that the prevalence rate is also influenced by environmental conditions, occupation, diet and cultural habits. Studies with animals have shown the presence of antibody to T. gondii, but this does not seem to be the source of infection since Malaysians normally cook their meat well.

    Kiyu A, Teo B, Hardin S, Ong F
    Southeast Asian J Trop Med Public Health, 1991 Jun;22(2):211-5.
    PMID: 1948281
    The nutritional status of 641 children between the ages of 0 to 4 years old, from 835 households in 41 randomly selected rural villages with water supply in Sarawak were determined. Based on Waterlow's classification and the National Center for Health Statistics (NCHS) standards, 61% of the children were stunted and 44.1% were wasted. Based on Gomez's classification and the NCHS standards 81.9% of the children were malnourished. There was no sex difference in nutritional status. The percentage of malnourished children increased continuously with age while the percentage of children who were wasted increased from 6 to 36 months and then it leveled off. The percentage of stunted children also increased with age but the increase was sharpest in children who were 12 to 23 months old. It is noted that the Gomez classification overestimates the prevalence of undernutrition.

  15. Fulltext Performance of Osteoporosis Self-Assessment Tool (OST) in predicting osteoporosis - a review
    Subramaniam S, Ima-Nirwana S, Chin KY
    Int J Environ Res Public Health, 2018 07 09;15(7).
    PMID: 29987247 DOI: 10.3390/ijerph15071445
    Bone health screening plays a vital role in the early diagnosis and treatment of osteoporosis to prevent fragility fractures among the elderly and high-risk individuals. Dual-energy X-ray absorptiometry (DXA), which detects bone mineral density, is the gold standard in diagnosing osteoporosis but is not suitable for screening. Therefore, many screening tools have been developed to identify individuals at risk for osteoporosis and prioritize them for DXA scanning. The Osteoporosis Self-assessment Tool (OST) is among the first tools established to predict osteoporosis in postmenopausal women. It can identify the population at risk for osteoporosis, but its performance varies according to ethnicity, gender, and age. Thus, these factors should be considered to ensure the optimal use of OST worldwide. Overall, OST is a simple and economical screening tool to predict osteoporosis and it can help to optimize the use of DXA.

  17. Fulltext Risk of 28-day readmissions among stroke patients in Malaysia (2008-2015): Trends, causes and its associated factors
    Ang SH, Hwong WY, Bots ML, Sivasampu S, Abdul Aziz AF, Hoo FK, et al.
    PLoS One, 2021;16(1):e0245448.
    PMID: 33465103 DOI: 10.1371/journal.pone.0245448
    BACKGROUND AND OBJECTIVES: Risk of readmissions is an important quality indicator for stroke care. Such information is limited among low- and middle-income countries. We assessed the trends for 28-day readmissions after a stroke in Malaysia from 2008 to 2015 and evaluated the causes and factors associated with readmissions in 2015.

    METHODS: Using the national hospital admission records database, we included all stroke patients who were discharged alive between 2008 and 2015 for this secondary data analysis. The risk of readmissions was described in proportion and trends. Reasons were coded according to the International Classification of Diseases, 10th Edition. Multivariable logistic regression was performed to identify factors associated with readmissions.

    RESULTS: Among 151729 patients, 11 to 13% were readmitted within 28 days post-discharge from their stroke events each year. The trend was constant for ischemic stroke but decreasing for hemorrhagic stroke. The leading causes for readmissions were recurrent stroke (32.1%), pneumonia (13.0%) and sepsis (4.8%). The risk of 28-day readmission was higher among those with stroke of hemorrhagic (adjusted odds ratio (AOR): 1.52) and subarachnoid hemorrhage (AOR: 2.56) subtypes, and length of index admission >3 days (AOR: 1.48), but lower among younger age groups of 35-64 (AORs: 0.61-0.75), p values <0.001.

    CONCLUSION: The risk of 28-day readmission remained constant from 2008 to 2015, where one in eight stroke patients required readmission, mainly attributable to preventable causes. Age, ethnicity, stroke subtypes and duration of the index admission influenced the risk of readmission. Efforts should focus on minimizing potentially preventable admissions, especially among those at higher risk.

  18. Fulltext Domestic violence and decision-making power of married women in Myanmar: analysis of a nationally representative sample
    Kabir R, Haque M, Mohammadnezhad M, Samad N, Mostari S, Jabin S, et al.
    Ann Saudi Med, 2019;39(6):395-402.
    PMID: 31804139 DOI: 10.5144/0256-4947.2019.395
    BACKGROUND: Women in Myanmar are not considered decision makers in the community and the physical and psychological effect of violence makes them more vulnerable. There is a strong negative reaction, usually violent, to any economic activity generated by women among poorer and middle-class families in Myanmar because a woman's income is not considered necessary for basic survival.

    OBJECTIVE: Explore the relationship between domestic violence on the decision-making power of married women in Myanmar.

    DESIGN: Cross-sectional.

    SETTING: National, both urban and rural areas of Myanmar.

    PATIENTS AND METHODS: Data from the Myanmar Demographic and Health Survey 2015-16 were used in this analysis. In that survey, married women aged between 15 to 49 years were selected for interview using a multistage cluster sampling technique. The dependent variables were domestic violence and the decision-making power of women. Independent variables were age of the respondents, educational level, place of residence, employment status, number of children younger than 5 years of age and wealth index.

    MAIN OUTCOME MEASURES: Domestic violence and decision-making power of women.

    SAMPLE SIZE: 7870 currently married women.

    RESULTS: About 50% respondents were 35 to 49 years of age and the mean (SD) age was 35 (8.4) years. Women's place of residence and employment status had a significant impact on decision-making power whereas age group and decision-making power of women had a relationship with domestic violence.

    CONCLUSION: Giving women decision making power will be indispensable for the achievement of sustainable development goals. Government and other stakeholders should emphasize this to eliminate violence against women.

    LIMITATIONS: Use of secondary data analysis of cross-sectional study design and cross-sectional studies are not suitable design to assess this causality. Secondly the self-reported data on violence may be subject to recall bias.

    CONFLICT OF INTEREST: None.

    PMID: 24522128 MyJurnal
    Intestinal parasitic infections are important public health problems among underprivileged communities. This study was carried out to evaluate the infection rate of intestinal parasites among aborigine children at Pos Sungai Rual, Kelantan, Malaysia. A total of 111 faecal samples from aborigine children aged 4-12 years were screened for intestinal parasites by direct smear technique. Harada-Mori culture was also performed to identify hookworm and Strongyloides stercoralis larvae. The results showed that 87.4% of the children examined were positive for one or more parasites. Intestinal parasites were significantly lower in boys (78.7%) as compared to girls (93.8%). The infection occurred in very young children aged 4-6 years (80.0%) and the percentage of parasite-positive cases appeared to be significantly higher (92.9%) among the children aged 7-9 years. Trichuris trichiura was the most common parasite found in aborigine children (65.8%). Low socioeconomic status, poor environmental sanitation and poor personal hygiene are possible contributing factors that increase the rate of intestinal parasitic infections among the children. Thus, the parasitic diseases will continue to threaten the people's health especially among communities from rural areas if no appropriate actions are taken to diminish the transmission of the parasites.
