During a routine medical examination of 5280 government employees (2736 males, 2544 females; age range 17 to 66 years; 3386 Chinese, 1252 Malays, 508 Indians and 134 other ethnic groups) diabetes was found in 31 (0.59%). The prevalence was higher in males (0.95%) than in females (0.20%). The highest prevalence was in the age-group 50 to 59 years (5.4%); at ages 30 to 66 years, the overall prevalence was 2.18%. The prevalence of diabetes is higher in Indians (2.76%) than in Chinese (0.30%) and Malays (0.48%); the difference is statistically significant, as it also is in the age-group 30 to 66 years (Indians 6.36%, Malays 1.39%, Chinese 0.9%). Of the 31 cases, only four were previously known and only nine were overwieght. The possible reasons for the higher prevalence of diabetes in Indians are discussed.
Domiciliary deliveries have always been the responsibility of traditional birth attendants. Since Independence, acquired in 1957, educated young women have been trained as auxiliary midwives and sent to serve in rural communities where they usually are met with resistance by the established traditional birth attendants. To counter this and to incorporate the traditional birth attendants into the health team, new roles were developed for each so that the two would be able to cooperate and support each other rather than rival and antagonise each other. A specific experience in one area of Malaysia is examined as an example.
Since Independence, gained in 1957, major changes have occurred in the rural areas of Malaysia not least amongst which has been the provision of maternal and child care services to hitherto neglected areas. In the first part of this paper, the demographic and disease patterns are described. The second part outlines the general development efforts and describes in greater detail the rural health services that have been organized in Malaysia. In the concluding section, changes in mortality and morbidity are examined.
Three indigenous Malay surgical procedures, namely circumcision by the mudim, bone-setting by the bomoh patah and cupping, are described. It is noted that complications are associated with both circumcision and bone-setting, and suggestions are made of possible health measures to cope with the situation.
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.
In Malysia, the proportion of children fully immunized againest diphtheria is generally low (20%). On the other hand, the Schick conversion rate rises with age and reaches 90% by 11 years of age. It is noted that asymptomatic carriers are an important epidemiological factor in diphtheria and that carrier rates for school children are high (prevalence of 7.5% while the rate of coloization with C. diphtheriae over a period of one year was 30%). Although immunization protects against clinical diphtheria, it does not prevent the carrier state. Thus, for the control of diphtheria, one should aim for 100% compliance. Some suggestions as to how higher levels of immunity may be achieved are described.
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).
Anthropometric and parasitological data from cross-sectional studies of two groups of primary school children (Group I of Indian origin, 325 boys and 259 girls, age = 7 years; Group II of Malay origin, 284 boys and 335 girls, age = 7-9 years) from two different ecological settings in Peninsular Malaysia were examined for epidemiological evidence of an association between hookworm infection and protein-energy malnutrition. In both ecological groups, significant weight, height and haemoglobin deficits were observed in children with hookworm infection after adjustment for covariables including Ascaris and Trichuris infection intensities and other child and family characteristics. The deficits were related to the intensity of infection based on egg counts. These findings suggest that hookworm may be an important determinant of chronic protein-energy malnutrition, as well as anaemia, in areas where diets are generally inadequate in protein, energy, and iron. Well-controlled intervention studies are needed to confirm these observations.
Hereditary haemolytic anaemias have been found to be a significant cause of haemolytic disease in West Malaysia. This paper reports a micromapping study of 916 healthy Malay males from June to August 1983 to determine the distribution of the relevant thalassaemia genes in West Malaysia. Beta thalassaemia trait was found in 2.18%, HbE 3.49% and alpha thal2 (alpha+) trait in 26%. Of the sixteen transfusion dependant Malay thalassaemic patients at the Paediatric Unit, National University of Malaysia, eight patients had HbE beta thalassaemia and the rest are beta thalassaemia major; these patients who are transfusion dependant receive inadequate treatment. Prevention is the only resort.
