    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.

    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.

    Noor Azian MY, Hakim SL, Sumiati A, Norhafizah M
    Southeast Asian J Trop Med Public Health, 2006 Jan;37(1):58-61.
    PMID: 16771213
    The objective of this study was to determine exposure to cysticercosis among a rural population in a selected village in Ranau, Sabah, Malaysia. A total of 135 serum samples were analyzed. The result showed that the seroprevalence of cysticercosis antibodies was 2.2%. There was no significant difference in the seroprevalence among age groups (p=0.307). Even though there was a slightly higher antibody titer in males compared to females, the difference was not significant (p=0.400). The results indicate evidence of exposure to cysticercosis in this rural population.

    PMID: 10772555
    A study on prevalence and risk factors of Giardia duodenalis infection was conducted in rural communities of Malaysia. A total of 917 individuals between 2-70 years old (431 males and 486 females), participated in this study. The overall prevalence of G. duodenalis infection was 19.2%. The prevalence was significantly different between different age groups, but not genders. Our study indicated that age < or = 12 years old and the presence of family members infected with G. duodenalis were the risk factors of infection. Person-to-person contact within the family members was the possible mode of transmission. Health education on personal hygiene, together with the treatment of the infected people, may help in reducing and controlling this infection in these communities.

  5. 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.

  6. 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.

  7. Fulltext Overweight among primary school-age children in Malaysia
    Naidu BM, Mahmud SZ, Ambak R, Sallehuddin SM, Mutalip HA, Saari R, et al.
    Asia Pac J Clin Nutr, 2013;22(3):408-15.
    PMID: 23945411 DOI: 10.6133/apjcn.2013.22.3.18
    This study is a secondary data analysis from the National Health Morbidity Survey III, a population-based study conducted in 2006. A total of 7,749 children between 7 and 12 years old were recruited into the study. This study seeks to report the prevalence of overweight (including obesity) children in Malaysia using international cut-off point and identify its associated key social determinants. The results show that the overall prevalence of overweight children in Malaysia was 19.9%. The urban residents, males, Chinese, those who are wealthy, have overweight or educated guardians showed higher prevalence of overweight. In multivariable analysis, higher likelihood of being overweight was observed among those with advancing age (OR=1.15), urban residents (OR=1.16, 95% CI: 1.01-1.36), the Chinese (OR=1.45, 95% CI: 1.19-1.77), boys (OR=1.23, 95% CI: 1.08-1.41), and those who came from higher income family. In conclusion, one out of five of 7-12 year-old-children in Malaysia were overweight. Locality of residence, ethnicity, gender, guardian education, and overweight guardian were likely to be the predictors of this alarming issue. Societal and public health efforts are needed in order to reduce the burden of disease associated with obesity.

  8. Fulltext Adults' perceptions of being overweight or obese: a focus group study
    Chang CT, Chang KH, Cheah WL
    Asia Pac J Clin Nutr, 2009;18(2):257-64.
    PMID: 19713186
    The objective of this study was to explore the perception of, feelings and attitudes toward overweight or obesity, and the perceived barriers to weight loss among native adults from lower socio-economic background. A total of six gender- and ethnic-specific focus groups consisted of 38 overweight and obese purposefully and criterion selected adults (21 women and 17 men), participated in this study. An unstructured discussion guide based on the study objectives were used for the focus groups. The results showed that some participants perceived themselves as ugly, felt ashamed of their body size and were frustrated because they did not desire to be overweight. Due to their excess weight, most also expressed they were less effective in their work performances. Although some participants had negative attitudes toward themselves because of excess weight, this appeared to link to self-stigmatization rather than anti-obesity discrimination. The participants remained in the Pre-contemplation stage of losing weight probably because of perceived barriers such as difficulty to resist eating, lack of know how and previous failed attempts to lose weight. Importantly, this study provided some evidence that individuals in the Pre-contemplation stage are unable to take action to lose weight, even if effective strategies are suggested.

  9. Prevalence and patterning of maxillary premolar accessory ridges (MxPARs) in several human populations
    Mihailidis S, Scriven G, Khamis M, Townsend G
    Am J Phys Anthropol, 2013 Sep;152(1):19-30.
    PMID: 23913636 DOI: 10.1002/ajpa.22323
    We present new data on the prevalence and patterning of the maxillary premolar accessory ridge (MxPAR), a common but understudied morphological dental trait that is expressed as a linear elevation extending from the buccal cusp ridge to the medial sulcus of maxillary premolar teeth. A total of 579 sets of dental casts, representing six ethnic groups, were scored using the five-grade system proposed by Burnett et al. (2010). The frequency and distribution of the MxPAR were determined by tooth type, sex, side, locus and ethnicity, and the applicability of the scoring system was assessed. The MxPAR was found in approximately two-thirds of premolar teeth, more often on second than first premolars, and more often on the distal aspect of the occlusal surface than the mesial. There was some evidence that more pronounced forms of the feature occurred more often in males than females, and that there may be some directionality in its expression between sides. Variation was also noted in the frequency of occurrence and degree of expression of the MxPAR between ethnic groups. Intra- and inter-observer concordance rates for scoring the MxPAR were low, confirming that it was difficult to score the trait identically on two different occasions. Our findings have clarified the distribution of the MxPAR within the dentition and between ethnic groups, and highlighted the need for researchers to carry out thorough replicability studies and to decide on an appropriate breakpoint for determining presence or absence of this feature before embarking on genetic studies or bio-distance analyses.

    PMID: 7709757
    A study was conducted to compare the urinary iodine concentrations in populations from Pahang, Central Malaysia, with those in the capital city Kuala Lumpur, and to compare those of Malays from villages at Batu Talam, Batu Malim, FELDA Sungai Koyan and Hulu Sungai with neighboring aboriginal settlements at Lanai and Buntu. Two hundred and forty urine samples were collected randomly among the population (male 1 1 1 and female 129). The urinary iodine concentrations, measured by the ashing method, among Malays were as follows: Batu Talam 1.1-7.6 micrograms/dl, Batu Malim 1.4-6.6 micrograms/dl, FELDA Sungai Koyan 0.5-6.9 micrograms/dl and Hulu Sungai 0.6-9.9 micrograms/dl. Among aborigines, the urinary iodine levels were 0.1-2.9 micrograms/dl in Lanai and 1.7-6.5 micrograms/dl in Buntu. There was a significant difference in the levels of urinary iodine with regard to gender, but not regarding age. The aborigines had significantly lower iodine levels than Malays (P < 0.001). This difference was also significant with regard to location. The urinary iodine content in Kuala Lumpur was the highest and that in the aboriginal Lanai village was the lowest. Thus, the study showed that the levels of iodine in the urine were influenced by ethnicity and geographic location.

  13. Hepatic iron status in Malaysians and Singaporeans
    Loh TT, Chang LL
    Southeast Asian J Trop Med Public Health, 1980 Mar;11(1):131-6.
    PMID: 7403941
    Non-haemoglobin liver iron was estimated in 275 presumably normal individuals from Kuala Lumpur and Singapore at necropsy. Liver Iron concentrations were highest during the first two years after birth but declined sharply during childhood. They then rose gradually and reached a value of 20 mg/100gm in adult males. Liver iron concentrations of childbearing women remained low and it was only after menopause that values in women rose to those of males. Liver iron stores increased with age to a plateau of about 300 mg in adults, suggesting that this value may represent the adult size for liver iron store. Among the three major ethnic groups in Malaysia and Singapore, Chinese, being in a better socio-eonomic class, had larger liver iron stores. The median liver iron concentrations of Malaysians and Singaporeans, on the whole, were lower than those reported from western populations and as many as 35 per cent of the women were in a subclinical state of iron deficiency.

    PMID: 15563435
    Lifestyle and disease patterns in Malaysia have changed following rapid economic development. It is important to find out how these changes have affected the nutritional status and health behaviour of the population, especially school children and adolescents. Therefore a survey on school children's and adolescents' health behaviours and perception in Kuala Lumpur was initiated. This paper only reports the observed body mass status of the school children. A total of 3620 school children were selected in this survey using the method of multi-stage sampling. The students were surveyed using pre-tested questionnaires while weight and height were measured by the research team in the field. Using the cut-off of BMI-for-age >or= 95th percentile and <5th percentile for overweight and underweight respectively, there were a total of 7.3% of overweight students and 14.8% of underweight students. When analysed by gender; 7.5% of boys and 7.1% girls were overweight, while 16.2% of the boys and 13.3% of the girls were underweight. The youngest age group (11 years old) had the highest prevalence of underweight as well as overweight. With increasing age, the prevalence of underweight and overweight decreased and more children were in the normal weight range. The overall prevalence of overweight among the three ethnic groups was similar. However the prevalence of underweight was highest among the Indian students (24.9%), followed by Malays (18.9%) and Chinese (9.5%) (P <0.001). The results showed that both the problems of under- and over-nutrition co-exist in the capital city of Malaysia. The promotion of healthy eating and physical activities is required to address the problems of under- and over-nutrition in order to build up a strong and healthy nation in the future.

    Prolonged standing can cause discomfort on the body of the workers and can lead to injury and occupational disease. One of the ergonomic intervention is through improving the work-rest scheduling. The purpose of this study are to identify the fatigue level from the perception of the worker and to investigate the impact of the work-rest scheduling to the standing workers for 12 h working time with a different gender. This study involved two methods which are self-assessment of the worker and direct measurement by using electromyography (EMG). For self-assessment, 80 workers have been interviewed using questionnaire in order to identify the fatigue level. For direct measurement, EMG was attached to the 15 selected workers at their respective leg and lower back to analyse the muscle efforts. In terms of perception, the results show the discomfort and fatigue level at the lower body region in the following order as foot ankle, lower back and leg. There is a significant difference between gender on discomfort pain for foot ankle and leg. The results show short frequent break by 10 min can reduce the fatigue at the leg and infrequent long break is preferable in order to reduce the fatigue at the lower back. In conclusion, it was found that prolonged standing affect the muscle fatigue and discomfort especially lower extremities such as foot ankle, lower back and leg. Besides that, different type of work rest scheduling and gender have significant result towards the muscle fatigue development.

    PMID: 17215180
    A nutritional status survey of Orang Asli (Aboriginal) adults in Lembah Belum, Grik, has been conducted involving a total of 138 subjects. Jahai (58.7%) was the main ethnic group as compared to that of Temiar (41.3%). Based on the Body Mass Index (BMI) characteristics, the majority (63.2%) of the respondents were normal, 26.7% underweight and 10.1% were either overweight or obese. However, by using two different indices of waist circumference and waist-to-hip ratio, 1.6% and 10.8% of the total respondents revealed abdominal obesity, respectively. Measurement of mid upper arm muscle circumference (MUAMC) indicated that about 40% showed nutritional insufficiency whereas 0.8% showed over-nutrition. Body fat classification revealed that 53.4% of the respondents were thin, 45.8% at normal level and only 0.8% were obese. Student's t-test revealed a significant difference in anthropometric indices of body weight, height, MUAMC, triceps, sub-scapular, supra-iliac and body fat according to gender. Meanwhile, analysis of variance (ANOVA) showed significant differences in body weight, waist circumference, WHR and body fat according to different age categories. It was also found that those who smoked had lower BMI compared with non-smokers. Alcohol consumption was associated with higher BMI and WHR among the respondents. Pearson's correlation test between anthropometric measurements and socio-economic and demographic factors showed that ethnic group was the strongest variable.

    PMID: 23651425 DOI: 10.1111/bju.12037
    OBJECTIVE: To evaluate the efficacy and safety of long-acting i.m. testosterone undecanoate (TU) in Malaysian men with testosterone deficiency (TD).

    PATIENTS AND METHODS: A total of 120 men, aged 40-70 years, with TD (serum total testosterone [TT] ≤ 12 nmol/L) were randomised to receive either i.m. TU (1000 mg) or placebo. In all, 58 and 56 men in the placebo and treatment arm, respectively, completed the study. Participants were seen six times in the 48-week period and the following data were collected: physical examination results, haemoglobin, haematocrit, TT, lipid profile, fasting blood glucose, sex hormone-binding globulin, liver function test, prostate- specific antigen (PSA) and adverse events.

    RESULTS: The mean (sd) age of the participants was 53.4 (7.6) years. A significant increase in serum TT (P < 0.001), PSA (P = 0.010), haematocrit (P < 0.001), haemoglobin (P < 0.001) and total bilirubin (P = 0.001) were seen in the treatment arm over the 48-week period. Two men in the placebo arm and one man in the treatment arm developed myocardial infarction. Common adverse events observed in the treatment arm included itching/swelling/pain at the site of injection, flushing and acne. Overall, TU injections were well tolerated.

    CONCLUSIONS: TU significantly increases serum testosterone in men with TD. PSA, haemoglobin and haematocrit were significantly elevated but were within clinically safe limits. There was no significant adverse reaction that led to the cessation of treatment.

    PMID: 26521527
    Pregnancy among unmarried women may have negative social and health implications in Malaysia. The number of pregnancies among unmarried women has increased in Malaysia, but the socio-demographic profile of these women is unclear. This study aims to evaluate the characteristics of unmarried pregnant women and the factors associated with unmarried pregnancies among young women in Malaysia. We conducted a cross sectional study at six hospitals and six women's shelters in Peninsular Malaysia during 2011-2012. Unmarried pregnant women were compared with married pregnant women. Participants were interviewed using a structured questionnaire asking for socio-demographic data, family background, risky sexual behavior, social support and pregnancy details. A total of 484 women (239 unmarried and 245 married) were included in the study. Most unmarried subjects were adolescents, from urban areas, from a low socioeconomic group, and lived with parents prior to pregnancy. Age (OR=0.67; 95% CI: 0.61-0.74), studying status (OR=17.33; 95% CI: 2.65-113.19), alcohol use (OR=40.46; 95% CI: 2.51-652.38) exposure to pornographic material (OR=13.48; 95% CI: 3.24-56.01), contraceptive use (OR=0.20; 95% CI: 0.08-0.51), and social support (OR=0.90; 95% CI: 0.86-0.94) were all associated with unmarried pregnancy. These factors need to be considered when.designing an intervention program.

  20. Fulltext Knowledge and attitude of healthcare workers about Middle East Respiratory Syndrome in multispecialty hospitals of Qassim, Saudi Arabia
    Khan MU, Shah S, Ahmad A, Fatokun O
    BMC Public Health, 2014;14:1281.
    PMID: 25510239 DOI: 10.1186/1471-2458-14-1281
    BACKGROUND: With the increase in prevalence of Middle East Respiratory Syndrome (MERS), healthcare workers (HCWs) are at risk of acquiring and subsequently transmitting this lethal virus. In view of this, HCWs were evaluated for their knowledge of and attitude towards MERS in Saudi Arabia.
    METHODS: A cross sectional study was performed in two hospitals of Qassim region in Saudi Arabia. A total of 280 healthcare workers were selected to participate in this study. Knowledge and attitude were assessed by using self-administered and pretested questionnaire. Descriptive statistics were carried out to express participants' demographic information, mean knowledge score and mean attitude score of HCWs. Inferential statistics (Mann-Whitney U test and Kruskal Wallis tests, p < 0.05) were used to examine differences between study variables. Chi squares tests were used to assess the association between study variables and attitude questions. Spearman's rho correlation was used to identify the association between the knowledge, attitude scores.
    RESULT: Participants demonstrated good knowledge and positive attitude towards MERS. The mean scores of knowledge and attitude were 9.45 ± 1.69 (based on 13 knowledge questions) and 1.82 ± 0.72 (based on 7 attitude questions). The correlation between knowledge and attitude was significant (correlation coefficient: 0.12; P <0.001). HCWs were less educated about the management (42.4%), source (66%) and consequences of MERS (67.3%), while a majority of them were well aware of the hallmark symptoms (96%), precautionary measures (96%) and hygiene issues (94%). Although the majority of respondents showed positive attitude towards the use of protective measures (1.52 ± 0.84), their attitude was negative towards their active participation in infection control program (2.03 ± 0.97). Gender and experience were significantly associated with knowledge and attitude (P < 0.05).
    CONCLUSIONS: The findings of this study showed that healthcare workers in Qassim region of Saudi Arabia have good knowledge and positive attitude towards MERS. Yet there are areas where low knowledge and negative attitude of HCWs was observed. However, studies are required to assess the knowledge and attitude of HCWs at national level so that effective interventions could be designed as surveillance and infection control measures are critical to global public health.
