Fulltext Ecological basis of malnutrition among the Muruts of Sabah

Chen PCY

Med J Malaysia, 1983 Mar;38(1):9-14.
PMID: 6633346

A recent anthropometric study of Sabah reported that 37.1 percent of children were nutritional dwarfs, 12.5 percent were acutely malnourished and 9.4 percent were stunted and wasted. It was also noted that Muruts were among the top five most malnourished ethnic groups in Sabah. The present study looks at the ecological basis of malnutrition among Muruts and concludes that a variety of interrelated factors, including the lack of education, climatic and soil conditions, poverty, food habits and taboos as well as diseases from poor sanitation and malaria contribute to the presence of malnutrition among rural Muruts. It is recommended that a multidisciplinary approach be taken to control and prevent malnutrition among the Muruts and that the single most important measure aside from malaria control is education of the people and the development of marketable skills.

Fulltext Effects of environment on the growth of children

Chen ST

Med J Malaysia, 1986 Mar;41(1):72-6.
PMID: 3796354

A child's growth achievement depends on his genetic endowment and the environment in which he lives; Comparative studies of children of similar racial origin but growing under different environmental conditions have shown differences in their body size and shape. In general higher income families produce offspring with higher mean birth weight. This is largely due to better nutrition and care of mothers during pregnancy and childhood. Children from higher socioeconomic groups are on an average larger in size in terms of weight, height, head circumference, midarm circumference, crown-rump length and leg length. This is largely due to a better home environment including sanitation, nutrition, health and care enjoyed by the better-off children. .Generally urban children are larger than rural children mainly due to economic differences between the two areas. In most countries the secular trend to children getting larger still continues reflecting an improvement of living conditions with time. Unlike body size, body shape is less influenced by the environment and the change in body proportion brought about by environment is not permanent. In developing countries, children from higher socioeconomic families have generally thicker skinfolds. On the average, infants and preschool children of European ancestry have thicker triceps skinfolds compared with Negroes and Asians living in comparable environments. It is possible that this is due to long term adaptation to different climatic conditions.

Milk tolerance among malnourished school children in Malaysia

Chen ST, Domala Z

Asia Pac J Public Health, 1989;3(4):274-7.
PMID: 2638907 DOI: 10.1177/101053958900300405

1,256 malnourished children, aged seven to ten years, were selected for study, 575 from Kuala Langat, 416 from Wilayah Persekutuan and 265 from Ulu Selangor. Ninety-three percent of the children were from low socioeconomic groups with large family size, and most of their parents had only primary or no formal education. During the study period, children in Kuala Langat received daily milk supplementation for five days per week, those in Wilayah Persekutuan for two days per week, while those in Ulu Selangor did not receive any milk supplementation. The study shows that a majority of the malnourished primary school children liked to drink milk and that milk intolerance was not a problem among them.

Secular trend of growth in Malaysian children

Chen ST

J Singapore Paediatr Soc, 1990;32(3-4):102-7.
PMID: 2133745

Over the past hundred years in industrialised countries and recently in some developing countries, children have been getting larger and growing to maturity more rapidly. This paper compares the growth of Malaysian children with similar socioeconomic backgrounds but born about twelve years apart. Data were obtained from records of 227 children born between 1968 and 1973 and 238 children born between 1980 and 1985. The children were followed-up regularly at the University Hospital Child Health Clinic in Kuala Lumpur for a variable period from birth to five years of age. Measurements for their weight, length and head circumference were taken at each visit. There is a directional indication that boys and girls of the 1980-1985 cohort are taller, heavier and have bigger head circumferences from birth to five years of age and the difference widens as the child grows older. This study clearly shows that a positive secular trend has taken place in the last decade, reflecting an improvement of living conditions with time. The factors involved in the positive secular trend are manifold and the most important is probably nutrition.

Pneumonia and diarrhoeas: killers of toddlers in developing countries

Chen ST

Trop Geogr Med, 1975 Mar;27(1):103-8.
PMID: 806152

Pneumonia and diarrhoeas are an important cause of toddler mortality and morbidity in developing countries. Of the 147 children admitted to the University Hospital at Kuala Lumpur in 1971 for pneumonia and diarrhoeas 50 (34%) were found to be suffering from protein-calorie malnutrition of varying degrees of severity. The malnourished children tended to come from poorer homes, and to have a larger number of siblings born in rapid succession when compared with normal weight children. Anemia was more common among the malnourished children. The interaction of infection and malnutrition and the social implications of these diseases are important. It is vital that hospitals in developing countries promote health in addition to their traditional curative role.

Peritoneal dialysis in Asia

Cheng IK

Perit Dial Int, 1996;16 Suppl 1:S381-5.
PMID: 8728228

The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last three years from the straight-line systems with or without germicidal connection devices to the disconnect systems. In China and India, where PD has been introduced only recently, the disconnect systems are used almost exclusively. The disconnect systems are also the most popular systems in use in Japan and Taiwan. As data concerning the cost-effectiveness of different PD systems becomes available, it is likely that trend towards a more liberal use of disconnect systems will continue in the future. The usage of low calcium peritoneal dialysate and the average number of daily CAPD exchanges also vary among the Asian countries. Low calcium peritoneal dialysate has been introduced only in Japan, Hong Kong, and Singapore, with the highest utilization rate (90%) recorded in Singapore. The Philippines had the lowest average number of daily peritoneal exchanges (6L) among the countries surveyed, followed by Hong Kong (6.4L), China and Indonesia (7L), and the rest (8L). The use of a lower number of exchanges was introduced in some countries, initially, mainly as a cost-saving measure based on the assumption that Asians are of small body build. The justification for the continued use of a lower number of exchanges among Asian patients is debatable, but is supported by the acceptable, long-term clinical outcome of patients given this form of dialysis prescription. It is suggested that long-term prospective studies on dialysis adequacy and clinical outcome should be done in different ethnic groups in Asia to see if the similar guidelines with regard to dialysis adequacy can be applied uniformly to Orientals and Caucasians.

Fulltext A statistical study of attempted suicides in Singapore

Chia BH, Tsoi WF

Singapore Med J, 1974 Dec;15(4):253-6.
PMID: 4458068

This is a study of 169 cases of attempted suicides who had been referred to or who had consulted a private psychiatrist. These patients were interviewed, examined and treated either as out- or in-patient in private hospitals during the years 1968-1976. Their demographic and clinical data were analysed, presented and discussed. The reasons and motivations tor the act were also obtained and summarized. In the follow-up study conducted, it was discovered that schizophrenic patients who had attempted suicide carries the highest completed suicide risk.

Fulltext A survey of breast feeding practices in infants seen in general practice

Chia SF

Med J Malaysia, 1992 Jun;47(2):134-8.
PMID: 1494334

This is a study of infant feeding practices of 126 mothers. Seventy-seven mothers or 61.1% practised breast feeding. The typical breast feeding mother was more likely to be a Malay, with lower family income and residing in the rural area. The educational status of the mother was not an important factor in influencing her to breast feed. Health education on breast feeding should be intensified in schools to reinforce the implementation of the Malaysian Code of Ethics for Infant Formula Products.

Partial remission in type 1 diabetes and associated factors: Analysis based on the insulin dose-adjusted hemoglobin A1c in children and adolescents from a regional diabetes center, Auckland, New Zealand

Chiavaroli V, Derraik JGB, Jalaludin MY, Albert BB, Ramkumar S, Cutfield WS, et al.

Pediatr Diabetes, 2019 11;20(7):892-900.
PMID: 31237756 DOI: 10.1111/pedi.12881

BACKGROUND: Partial remission (PREM) by the insulin dose-adjusted HbA1c (IDAA1c) method has not been evaluated for the combined associations of ethnicity and socioeconomic status in children and adolescents with type 1 diabetes (T1D).
OBJECTIVE: To investigate prevalence and predictors of PREM defined by IDAA1c.
METHODS: Six hundred fourteen of 678 children (aged <15 years) with new-onset T1D (2000-2013) from a regional pediatric diabetes service (Auckland, New Zealand).
RESULTS: Overall rate of PREM at 3 months was 42.4%, and lower in Māori/Pacific children (28.6%; P = .006) and those of other ethnicities (28.8%; P = .030) compared with New Zealand Europeans (50.4%). Comparing the most and least deprived socioeconomic quintiles, the odds of PREM were lower among the most deprived (adjusted odds ratio [aOR] 0.44; P = .019). Lower rates of PREM were seen in children aged 0 to 4.9 years (23.8%) and 10 to 14 years (40.9%) than in children aged 5 to 9.9 years (57.4%; P

PMID: 15578123

This was an international study of women's health issues, based on an Official Study Tour in Southeast Asia (the Philippines, Thailand, Malaysia, Hong Kong, and Singapore) and Canada. The objectives of the study were to identify and compare current gaps in surveillance, research, and programs and policies, and to predict trends of women's health issues in developing countries based on the experience of developed countries. Key informant interviews (senior government officials, university researchers, and local experts), self-administered questionnaires, courtesy calls, and literature searches were used to collect data. The participating countries identified women's health as an important issue, especially for reproductive health (developing countries) and senior's health (developed countries). Cancer, lack of physical activity, high blood pressure, diabetes, poverty, social support, caring role for family, and informing, educating, and empowering people about women's health issues were the main concerns. Based on this study, 17 recommendations were made on surveillance, research, and programs and policies. A number of forthcoming changes in women''s health patterns in developing countries were also predicted.

Fulltext Effect of ethnicity and socioeconomic variation to the gut microbiota composition among pre-adolescent in Malaysia

Chong CW, Ahmad AF, Lim YA, Teh CS, Yap IK, Lee SC, et al.

Sci Rep, 2015;5:13338.
PMID: 26290472 DOI: 10.1038/srep13338

Gut microbiota plays an important role in mammalian host metabolism and physiological functions. The functions are particularly important in young children where rapid mental and physical developments are taking place. Nevertheless, little is known about the gut microbiome and the factors that contribute to microbial variation in the gut of South East Asian children. Here, we compared the gut bacterial richness and composition of pre-adolescence in Northern Malaysia. Our subjects covered three distinct ethnic groups with relatively narrow range of socioeconomic discrepancy. These included the Malays (n = 24), Chinese (n = 17) and the Orang Asli (indigenous) (n = 20). Our results suggested a strong ethnicity and socioeconomic-linked bacterial diversity. Highest bacterial diversity was detected from the economically deprived indigenous children while the lowest diversity was recorded from the relatively wealthy Chinese children. In addition, predicted functional metagenome profiling suggested an over-representation of pathways pertinent to bacterial colonisation and chemotaxis in the former while the latter exhibited enriched gene pathways related to sugar metabolism.

Fulltext Fruit and Vegetable Intake Patterns and Their Associations with Sociodemographic Characteristics, Anthropometric Status and Nutrient Intake Profiles among Malaysian Children Aged 1-6 Years

Chong KH, Lee ST, Ng SA, Khouw I, Poh BK

Nutrients, 2017 Jul 31;9(8).
PMID: 28758956 DOI: 10.3390/nu9080723

This study aimed to assess fruit and vegetable intake patterns and their associations with sociodemographic characteristics, anthropometric status and nutrient intake profiles among Malaysian children aged 1-6 years. Using the Malaysian dataset of South East Asian Nutrition Surveys (SEANUTS Malaysia), a total of 1307 children aged 1-6 years with complete datasets were included in this analysis. Dietary intake was assessed using age-specific, validated food frequency questionnaires. On average, Malaysian children consumed 0.91 and 1.07 servings of fruits and vegetables per day, respectively. Less than one-fifth of the children achieved the daily recommended servings of fruits (11.7%) and vegetables (15.8%). Fruit intake was associated with age, parental educational level and geographical region, and vegetable intake was associated with ethnicity and geographical region. There was little evidence of an association between fruit and vegetable intake and children's anthropometric status, but an adequate intake of fruits and vegetables contributed significantly and differently to children's micronutrient intake. Future nutrition interventions should focus on addressing the sociodemographic determinants and be tailored to the needs of the low consumers to more effectively promote and encourage the adequate intake of fruit and vegetables among young children.

Fulltext Population & social indicators of food and nutrition in Peninsular Malaysia

Chong YH

Med J Malaysia, 1982 Jun;37(2):134-40.
PMID: 6813659

Health, including nuirition is not independent but is closely associated with the social and economic environment. Malnutrition itself can cause death, but more commonly, it can cause considerable ill-health, physical retardation, impaired mental performance, loss in productivity and a decline in the quality of life. The effects of malnutrition as obstacles to socio-economic development are now well recognised. In a rapidly developing country like Malaysia, the nutritional and nutritionally-related problems present themselves with contrasting features. While population indicators such as toddler mortality, incidence of low birthweight and food balance sheet studies suggest an improving nutritional situation, methods of direct assessment have shown that chronic protein-energy malnutrition and anaemia are sWI common amongst pre-school children in both the rural and urban disadvantaged sectors. Moderate anaemia also affects a significant proportion of older children and women of childbearing age. Intestinal parasites, another indicator of under development at the local level, are ubiquitous in the rural setting and urban slums owing to unsatisfactory waste disposal. In striking contrast, diseases associated with dietary excesses and increasing affluence have now emerged as the major killers. This changing pattern of mortality and morbidity along the lines encountered by the industrialised societies is now dramatised by the fact that road accidents are now claiming a large number of victims. It is clear that while continued efforts should be given to the improvement of the nutritional health of both rural and urban poverty communities, little time should be wasted in considering the adoption of public health measures aimed at stemming the rising number of deaths associated with our increasing affluence, particularly those diseases that are nutritionally linked, such as coronary heart disease, hypertension and diabetes mellitus, not forgetting the increasing road toll afflicted by the motor vehicle.

Fulltext Suicide Precipitants Differ Across the Lifespan but Are Not Significant in Predicting Medically Severe Attempts

Choo CC, Chew PKH, Ho RC

Int J Environ Res Public Health, 2018 04 05;15(4).
PMID: 29621197 DOI: 10.3390/ijerph15040691

An important risk factor for suicide assessment is the suicide precipitant. This study explores suicide attempt precipitants across the lifespan. Three years of medical records related to suicide attempters who were admitted to the emergency department of a large teaching hospital in Singapore were subjected to analysis. These cases were divided into three age groups: Adolescence, Early Adulthood, and Middle Adulthood. A total of 540 cases were examined (70.9% females; 63.7% Chinese, 13.7% Malays, 15.9% Indians), whose ages ranged from 12 to 62. There were eight cases above the age of 65 years which were excluded from the analysis. Significant differences were found in precipitants for suicide attempts across the lifespan. Middle adults had relatively fewer relationship problems, and adolescents had comparatively fewer financial and medical problems. The models to predict medically severe attempts across the age groups using suicide precipitants were not significant. The findings were discussed in regards to implications in suicide assessment and primary prevention in Singapore, as well as limitations and recommendations for future research.

Fulltext Prevalence and Correlates of HIV and Hepatitis C Virus Infections and Risk Behaviors among Malaysian Fishermen

Choo MK, El-Bassel N, Adam PC, Gilbert L, Wu E, West BS, et al.

PLoS One, 2015;10(8):e0118422.
PMID: 26244844 DOI: 10.1371/journal.pone.0118422

Fishermen in Southeast Asia have been found to be highly vulnerable to HIV, with research evidence highlighting the role of sexual risk behaviors. This study aims to estimate the rate of HIV as well as hepatitis C virus (HCV) infections among Malaysian fishermen, and the risky sexual and injection drug use behaviors that may contribute to these infections. The study also includes an assessment of socio-demographic, occupational and behavioral correlates of testing positive for HIV or HCV, and socio-demographic and occupational correlates of risk behaviors. The study had a cross-sectional design and recruited 406 fishermen through respondent-driven sampling (RDS). Participants self-completed a questionnaire and provided biological specimens for HIV and HCV testing. We conducted and compared results of analyses of both unweighted data and data weighted with the Respondent-Driven Sampling Analysis Tool (RDSAT). Of the participating fishermen, 12.4% were HIV positive and 48.6% had HCV infection. Contrary to expectations and findings from previous research, most fishermen (77.1%) were not sexually active. More than a third had a history of injection drug use, which often occurred during fishing trips on commercial vessels and during longer stays at sea. Of the fishermen who injected drugs, 42.5% reported unsafe injection practices in the past month. Reporting a history of injection drug use increased the odds of testing HIV positive by more than 6 times (AOR = 6.22, 95% CIs [2.74, 14.13]). Most fishermen who injected drugs tested positive for HCV. HCV infection was significantly associated with injection drug use, being older than 25 years, working on a commercial vessel and spending four or more days at sea per fishing trip. There is an urgent need to strengthen current harm reduction and drug treatment programs for Malaysian fishermen who inject drugs, especially among fishermen who work on commercial vessels and engage in deep-sea fishing.

Fulltext Teacher Reporting Attitudes Scale (TRAS): confirmatory and exploratory factor analyses with a Malaysian sample

Choo WY, Walsh K, Chinna K, Tey NP

J Interpers Violence, 2013 Jan;28(2):231-53.
PMID: 22902514 DOI: 10.1177/0886260512454720

The Teacher Reporting Attitude Scale (TRAS) is a newly developed tool to assess teachers' attitudes toward reporting child abuse and neglect. This article reports on an investigation of the factor structure and psychometric properties of the short form Malay version of the TRAS. A self-report cross-sectional survey was conducted with 667 teachers in 14 randomly selected schools in Selangor state, Malaysia. Analyses were conducted in a 3-stage process using both confirmatory (stages 1 and 3) and exploratory factor analyses (stage 2) to test, modify, and confirm the underlying factor structure of the TRAS in a non-Western teacher sample. Confirmatory factor analysis did not support a 3-factor model previously reported in the original TRAS study. Exploratory factor analysis revealed an 8-item, 4-factor structure. Further confirmatory factor analysis demonstrated appropriateness of the 4-factor structure. Reliability estimates for the four factors-commitment, value, concern, and confidence-were moderate. The modified short form TRAS (Malay version) has potential to be used as a simple tool for relatively quick assessment of teachers' attitudes toward reporting child abuse and neglect. Cross-cultural differences in attitudes toward reporting may exist and the transferability of newly developed instruments to other populations should be evaluated.
