Some of the factors that could contribute towards influencing a mother's decision on breast-feeding and its success were discussed. One of the most important of such factors is the information and encouragement a mother receives, or fails to receive, when she needs it most. Such information, which is mostly non-medical, includes the technique of breast-feeding. Some of the negative influences on breast-feeding discussed include old wives' tales about diet and elements secreted through the mother's milk, the fear of losing one's figure, the fear by working mothers that breast-feeding is impossible to manage, the hospital practice of separating the mother and new-born for the first 24 hours, the shyness of breast-feeding babies in front of others, the lack of confidence in their own efficiency in breast-feeding, and the belief that breast-feeding is inconvenient. Some of the positive influences which can help towards successful preast-feeding are assistance and support from Breast-feeding Associations, a supportive husband and family, and the physician who makes a point of spending a few minutes to encourage his patient to breast-feed her forthcoming infant. The author called for combined efforts towards the restoration of breast-feeding as every infant's basic right.
A survey of the freshwater snails, Pila scutata and Bellamyia ingallsiana, as food consumed by the local population was carried out in Peninsular Malaysia. Of these two species the first is preferred; the sizes favoured are between 25--40 mm. Pila snails were found to be consumed by the three communities, viz. Malay, Chinese and Indian, in different ways. The various methods of preparing the snails for consumption are described. P. scutata is an intermediate host of the rat-lung worm, Angiostrongylus malaysiensis. As this worm presumably is the causative agent of human eosinophilic meningoencephalitis, the eating habits of the three races in consuming the snail in relation to the epidemiology of the disease was also discussed.
The results of the food consumption study suggested that the calorie and protein intakes of ID and 20 malnourished preschool children in the study area were much lower than the RDA and thus these children should benefit from a supplementary feeding project. However, after 42 days of supplementation with Nutri-Pak, the project's objective of increasing by 5%, the percent standard weight for age of at least 60% of the subjects was not achieved since only one child's weight reached this target. From the records of monitoring, it was noticed that the low consumption of Nutri -Pak. a partial replacement by the the food supplement of the children's diet in the home. uncooperative mothers, and illness or disease factors had contributed to the much lower weight gains than expected in most of the children.
Relatively few cases of myocardial infarction associated with coronary artery atherosclerosis have been described previously in macaques. In this study the authors report the prevalence and characteristics of coronary artery atherosclerosis and myocardial infarction in 10 rhesus (Macaca mulatta) and two cynomolgus (Macaca fascicularis) macaques that were fed atherogenic diets for 16 months or longer. Our findings show clearly that myocardial infarction occurs in macaques with diet-induced atherosclerosis. The frequency seems to be related to the species, composition of the atherogenic diet, and length of time fed the atherogenic diet. The myocardial lesions are remarkably similar to those described in human beings in terms of location and gross and microscopic characteristics. The characteristics of coronary artery atherosclerosis, including the occurrence of thrombosis, severe stenosis, mineralization, atheronecrosis, and sterol clefts, especially in animals fed the atherogenic diets for longer periods of time, also closely resemble those of the arterial lesions found in human beings. The greatest prevalence of myocardial infarcts was found in rhesus monkeys fed a cholesterol-containing diet with 40% of calories supplied by peanut oil and in cynomolgus macaques from Malaya that were fed the same amount of cholesterol with 40% of calories from lard. Electrocardiographic abnormalities as well as the occurrence of unexpected and relatively sudden death in several of these nonhuman primates are also consistent with signs frequently observed in human beings.
The nutritional status of 158 soldiers drawn from four army camps in Selangor, Negeri Sembilan and Pahang has been assessed by biochemical procedures, nutritional anthropometry and dietary (chemical) analysis. Biochemical assessment showed that with the exception of thiamin and riboflavin nutriture, the nutritional status of the soldiers appeared generally satisfactory and seemed to have improved slightly over those examined by the Inter-Departmental Committee on Nutrition and National Defence (ICNND), USA, in 1962 by similar methods. The anthropometric assessment indicated that the present day soldiers have the same mean height as those examined in 1962. Although they appeared slightly heavier, obesity did not seem to be a problem. Chemical analysis of their diet showed that there is room for improvement in the dietary supply of vitamin A and some of the water-soluble vitamins, particularly riboflavin, thiamin and vitamin C. There was also a significant discrepancy between the nutritional content of the chemically-analysed cooked meals and those calculated from the ration scales using Food Composition Tables, suggesting a need to review the current system of food supply,

As part of a research programme concerned with the need to lighten the load carried by soldiers engaged in long foot patrols, a field experiment was undertaken in West Malaysia. For 12 d a group of 15 men consumed 7.4 MJ/d (1770 kcal/d) whilst a control group of 14 men ate 12.9 MJ/d (3080 kcal/d); both groups expended on average about 15.8 MJ/d (3770 kcal/d). The low-energy group incurred an energy deficit of 98 MJ (23 410 kcal) with a weight loss of 3.9 kg, whereas corresponding figures for the control group were 37 MJ (8840 kcal) and 2.4 kg. Before, during and after the energy deprivation phase, assessment was made of work capacity (estimated VO2 max), vigilance and military skills but no difference was found between the groups.
Perinatal mortality rates have been gradually declining in all countries. The initial decline mainly resulted from improvements in the late foetal mortality rates. Later with improvements in neonatal care, early neonatal mortality rates also improved. The developed countries have consistently shown better results than the developing countries, an indication of the higher standard of living, general health as well as the delivery of health care in these countries. In the Singapore situation, a rapid improvement in perinatal mortality was initially observed due to improvements in the late foetal mortality, followed later by reduction in the early neonatal mortality due to upgrading of neonatal intensive care. The perinatal mortality rate is lowest in the Chinese compared to the Indians and Malays, most likely due to the dietary practices of the three ethnic groups in Singapore; while the Chinese encourage extra nutrition in the pregnant female, the Malays and Indians tend to practise dietary restriction during this period. The improved nutrition of the pregnant mother is a factor in improving the perinatal mortality.
A study of food ideology and eating behavior in a Malay village demonstrates that the relationship between belief and action is complex and not always predictable. Over-reliance upon stated beliefs, and generalizations derived from particular ecological settings, have influenced investigators into making universal and logical statements about Malay eating behavior and its health consequences--a logic which, however, does not always jibe with reality. Food ideology, like any other portion of a belief system, is subject to innovation, interpretation and rationalization, and contains within it 'rules to break rules' which assure the continued integrity of the symbolic system by patterning what might otherwise be seen as rifts in its fabric. An understanding of eating behavior must be based both on a knowledge of the subsidiary, as well as primary, clauses of food ideology, and on direct observation of the behaviors elicited by these beliefs and modified by the setting, the situation and the individual.
Traditionally, Malaysian women (Malay, Indian and Chinese) breastfed their infants as a matter of course and for an extended period of time; only elite Chinese women might have resorted to a wet-nurse. But the introduction of condensed and dehydrated milk in colonial Malaya from the late nineteenth century, and the later marketing also of commercially manufactured baby foods, led to some variation in traditional practice. Structural changes, industrialiZation and urbanisation affected social as well as economic life, and again these broad changes had an impact on infant feeding. Today, few women remain unfamiliar with the wide range of infant food products sold in the most isolated provision shops. This paper focuses on key sociological factors that might predict the frequency and duration of breastfeeding and weaning patterns. The data analysed below, collected during semi-structured interviews with 278 women presenting at Maternal and Child Health Clinics in Peninsular Malaysia, are in part confusing. They suggest that the women most likely to bottle feed only or to breast feed for a short period, and to use commercial baby foods, are young, with one child only, who reside in urban or peri-urban areas and have a reasonable household income. Higher educated women, and women whose husbands are in non-traditional occupations, are also less likely to breast feed or to do so for an extended period. But the profile of infant feeding practices is by no means clear. One of the shortcomings of the study relates to the method of collection of data, and highlights the need for detailed ethnographic studies to better explore the variability and complexity of the patterns of infant feeding.
We conducted 2 case-control studies with Malaysian and Hong Kong Chinese and investigated the association between salted fish intake and nasopharyngeal carcinoma (NPC). Both studies show a highly significant association between salted fish intake, especially during childhood, and NPC. Furthermore, from our results we estimate that the majority of NPC cases occurring in the southern Chinese can be attributed to their consumption of this food early in life.
Problems with assessing the effect of maternal nutrition and lactation performance are presented in relation to a conceptual mathematical ziggurat. Difficulties, variations and flows are to be found in stages of this sequence of "logic" [e.g., assessment of maternal nutrition, volume and composition of breast milk, nutritional satisfactions of the nursling). It is concluded that the various steps in this process of reasoning are subject to much more variation and adaptation than appreciated. Much so-called "faltering" in the second trimester is physiologically normal ("pseudo-faltering").
