Interaction
between vitamin E and glutathione in rat brain: Effect of chronic
ethanol administration
Sara Rani Marcus, MV Chandrakala and HA Nadiger
The
protection against ethanol-induced lipid peroxidation is rendered
by antioxidants such as vitamin E and glutathione (GSH) interacting
with each other and also functioning independently. A study of the
levels of GSH and activities of glutathione peroxidase (GP), glutathione
reductase (GR) and glutathione transferase (GST) in the cerebral cortex
(CC), cerebellum (CB) and brain stem (BS) of vitamin E-supplemented
and -deficient rats subjected to ethanol administration for 30 days
was carried out. Chronic ethanol administration to vitamin E-supplemented
rats elevated GP, GR and GST activities in the three regions and GSH
levels in the CB. Chronic ethanol administration to vitamin E-deficient
rats elevated GR activity in the three regions and GP activity in
the CC and CB, decreased GST activity in the CC and CB, but did not
alter GSH levels compared with normal rats subjected to chronic ethanol
administration. The results indicate that vitamin E helps to maintain
GSH levels to combat increased peroxidation while its absence has
a deleterious effect.

Dietary
fiber content and composition of fruits in Taiwan
Su-Chien Chang, Meei-Shyuan Lee, Chia-Jung Lin and Mou-Liang Chen
Forty-one
fresh fruits frequently consumed in the Taiwan area were analysed
for their dietary fiber content by an enzymatic-gravimetric method.
Total dietary fiber (TDF) of these fruits ranged from 0.2 g (per 100
g edible weight) in grapes to 8.6 g in eggfruit. In citrus fruit,
the proportion of soluble fiber in TDF was more than 50%. However,
in some fruits like guavas and waxapple, soluble fiber took less than
30% of TDF. Soluble fiber in almost all fruit was comprised of a large
amount of uronic acids, while the composition of insoluble non-cellulose
polysaccharides (INCP) varied a great deal. Mangos and pummelos of
different varieties were different in their sugar composition of INCP.
Insoluble non-cellulose polysaccharides of a crisp type of persimmon
had more arabinose and galactose, but those of soft persimmon contained
mainly xylose. These results show that different types of fruit are
distinct in their composition and hence, the properties of their dietary
fiber. These data are useful for dietary assessments in Taiwan and
South-East Asia.

The
impact of an iodine deficiency disorders control program in West Sumatra,
Indonesia
Siti Muslimatun, Rainer Gross, Drupadi HS Dillon and Werner Schultink
A cross-sectional study on iodine deficiency disorders (IDD) status
was conducted in a known endemic area where three types of IDD intervention
(iodized oil capsule, iodized salt and iodinated water) were employed.
A total of 238 children of 810 years of age from eight public
elementary schools were included in the study. In addition to selected
socio-economic and anthropometric data, output (iodine level in salt,
iodine content in drinking water, iodized oil coverage) and outcome
(goiter by palpation, urinary iodine excretion (UIE) concentration)
were assessed. The total goiter prevalence (all were in grade 1) was
19% (mild IDD). The median UIE concentration was 193.5 µg/L
(iodine-replete condition). Iodized oil capsule coverage was 61%,
and 55% of those children received their latest capsule less than
1 year prior to the time of the study. Iodine level in salt was 14.4
± 9 p.p.m. The iodine level in iodine supplemented drinking
water was 11.7 ± 8.2 µg/L, while in surface water it
was 12.2 ± 4.7 µg/L. Goiter was not associated with any
of the three types of iodine supplementation, while UIE level was
significantly associated only with iodized salt (P < 0.001), which
suggested that, despite some problems in the universal salt iodization
program, iodized salt was the most effective agent of the IDD control
program at the community level. However, more research is needed to
better understand the impact indicators of IDD control programs.

The
role of income and education in food consumption and nutrient intake
in a Chinese population
Xilin Yang, Bridget H-H Hsu-Hage, Huiguang Tian, Gang Hu, Qina Dong,
Junhua Wu and Mark L Wahlqvist
The purpose of this study was to investigate the role of socio-economic
status in the transition of food consumption and nutritional status
in a Tianjin population and to identify some related underlying nutritional
problems in this population. A random representative sample of appproximately
nine million people in Tianjin was obtained using the stratified multistage
cluster sampling method. A total of 2236 eligible subjects (1096 men
and 1140 women) aged between 15 and 64 years were enrolled in the
autumn of 1992. Food weighing plus a three-day food record method
were used to assess food consumption and nutrient intakes. The population
was categorized into four income groups by average per capita income
and three educational groups by years of education. There were marked
differences in daily mean consumption of foods among groups with different
income levels and educational attainment after adjustment for confounding
factors. The low income and/or least education group consumed more
cereals while the high income and/or most educated group consumed
more fruit, milk and meat. Due to the differences in food consumption,
intakes of protein, fat, riboflavin, calcium, selenium, zinc and vitamin
E increased while intakes of carbohydrate and manganese decreased
with increasing levels of income and education. Vitamin A, calcium
and riboflavin intakes were low in all groups classified by either
income or education. Vitamin A intake was lower in the low income
group than in the other three groups but intakes of calcium and riboflavin
were higher in the high income and/or the most educated group than
in the other groups. Socio-economic status plays an important role
in food consumption and nutritional status in this population. Low
intakes of vitamin A, calcium and riboflavin exist in all socio-economic
groups. However, higher income and/or educational attainment contribute
to increased intakes of calcium and riboflavin. Higher income also
relates to an increased intake of vitamin A..

Nutrition
and the Malaysian Healthy Lifestyle Programme: challenges in implementation
Tan
Sri Dato' Dr Abu Bakar bin Suleiman and Tee E Siong
There
are significant differences in the food consumption patterns of countries.
In the lower income countries, most of the energy intake is derived
from cereals and starchy roots. On the other hand, the intake of these
carbohydrate foods is much lower in the economically developed countries
and more of the energy is derived from added fats, alcohol, meat,
dairy products and sweeteners. The contribution of energy from various
food groups has changed markedly over the past three decades. With
increasing national wealth there is a general tendency for the consumption
of cereal foods to decline, whereas the consumption of added fats,
alcohol, meat and dairy products has increased over the years. Similar
changes have also been observed for Malaysia. These dietary alterations,
as well as other lifestyle changes, have brought about a new nutrition
scenario in many developing countries. These countries are now faced
with the twin problems of malnutrition, that is, undernutrition among
some segments of the population and diet-related chronic diseases
in other groups; for example, obesity, hypertension, coronary heart
disease, diabetes and various cancers. In Malaysia, deaths due to
diseases of the circulatory system and neoplasms have been on the
rise since the 1960s. The former has been the most important cause
of death in the country for more than 15 years, with cancer ranking
third for almost 10 years. Epidemiological data collected from different
community groups showed increased prevalences of various risk factors
amongst Malaysians. In view of the changed nutrition scenario in the
country, intervention programmes have been reviewed accordingly. The
Healthy Lifestyle (HLS) Programme was launched in 1991 as a comprehensive,
long-term approach to combating the emerging diet-related chronic
diseases. For six consecutive years one thematic campaign per year
was carried out; namely, coronary heart disease (1991), sexually transmitted
diseases (1992), food safety (1993), childhood diseases (1994), cancers
(1995) and diabetes mellitus (1996). To further strengthen health
promotion among the community, another series of activities to be
carried out under the second phase of the HLS programme from 1997
to 2002 was launched within the framework of the National Plan of
Action on Nutrition (NPAN) for Malaysia. In view of the importance
of diet and nutrition in the causation and prevention of chronic diseases,
the theme for the first year of this phase was Healthy Eating. It
is clear that nutrition education for the community in order to inculcate
a culture of healthy eating is the long-term solution. A series of
guidelines have been prepared for dissemination to the public via
a variety of media and approaches, and with the collaboration of various
government and non-governmental organisations. The implementation
of the programme is, however, a challenge to health and nutrition
workers. There is a need to examine the strategies for nutrition education
to ensure more effective dissemination of information. The challenge
is to determine how best to promote healthy eating within the present
scenerio of rapid urbanisation, 'western' dietary pattern influence,
a whole barrage of convenience and 'health' foods, and nutrition misinformation.
We would like to share our experiences in the approaches taken and
our concerns with other countries in the region given that various
opportunities exist for collaboration.

Future
directions in nutrition support
Julie Bines
The
provision of nutrition support to patients in hospital and at home
has advanced significantly over the past decade. Enteral or parenteral
nutrition can be safely administered in patients of any age, size
or disease state when care is taken to individually tailor nutrition
therapy and monitor for potential complications. Nutritional support
is increasingly recognised as an integral component of disease treatment
protocols. In the future, it is likely that nutrition support will
increasingly focus on modifying specific metabolic effects of disease
by disease-specific nutrient manipulation. Adjuncts to nutritional
therapy, such as growth factors, may provide opportunities to enhance
intestinal adaptation and modify the metabolic response to stress.
Advances in enteral and parenteral nutrition delivery systems will
continue to improve with the aim of providing safe, effective and
socially acceptable techniques of delivering long-term nutrition support.
Nutrition support teams have proven their cost-effectivenes in the
past decade; however, they are under increasing pressure to adapt
to ever changing healthcare systems. The next decade will provide
challenges and opportunities not only for the enhancement of nutritional
management but also for the provision of evidence that specific nutritional
intervention improves clinical outcome.

Cost
and benefit of hospital, hospital- in- the- home and ambulatory care
nutrition support services
RA
Evans and BJG Strauss
The instigation of nutrition support, either via the enteral or parenteral
route, in individuals unable to maintain adequate nutrition via oral
means is based on the premise that such an intervention will reduce
both morbidity and mortality and improve quality of life. While there
is evidence that active nutrition support improves biochemical and
physiological parameters, health professionals are being called upon
to demonstrate the cost, benefits and outcomes of nutrition support
in the face of budget constraints and increasing demands on health
care. Cost savings have been made in hospital nutrition support through
increased use of enteral rather than parenteral nutrition support,
particularly in Intensive Care Units, and careful use of resources
when planning enteral nutrition support. Nutrition support of critically
ill and malnourished individuals can reduce morbidity and length of
stay. Benefits of home nutrition support programs include avoidance
of hospital bed costs and improved lifestyle and psychological well-being.
Our experience and that of the literature will be reviewed.

Solving
the micronutrient problem in the Asia Pacific region
Ian Darnton-Hill
Over two billion people, or more than one out of three
individuals throughout the world, are at risk of iron, vitamin A and
iodine deficiencies. Although countries of the Asia Pacific region
have generally shown a remarkable decline in the proportion of malnourished
children, micronutrient deficiencies remain significant public health
problems. The World Summit for Children in 1990, and the FAO/WHO International
Conference on Nutrition held in Rome in 1992, affirmed that the elimination
of the various forms of micronutrient malnutrition would constitute
a significant contribution to social, economic and public health development.
Governments and non-governmental organisations from virtually all
nations, together with the international development community, have
made the elimination of iodine deficiency disorders and vitamin A
deficiency important goals to be achieved by the end of the decade,
along with a substantial reduction in the levels of iron deficiency
anaemia. A further important factor in implementing multisectoral
micronutrient interventions is the cost-effectiveness of such interventions.
The three main complementary intervention strategies to controlling
and preventing micronutrient deficiencies are: (i) food-based approaches
such as fortification and dietary diversification; (ii) supplementation
when appropriate; and (iii) public health measures to control infection,
including incorporating micronutrients into other child survival activities
such as immunisation. Much of the global experience in these strategies
comes from countries of the Asia Pacific region, with some significant
examples of success.

Iodine
deficiency disorders in Sarawak, Malaysia
Andrew Kiyu, Zainab Tambi and Yahya Ahmad
The state of Sarawak in Malaysia has a high prevalence of iodine deficiency
disorders (IDD). This has been revealed through a review of goitre
surveys that were carried out in the State from the early 1970s to
the 1990s. The primary cause was low iodine intake. Contributory factors
were low iodine content in the soil and water as well as high cassava
consumption. Virtual elimination of IDD is one of the nutritional
goals of the IDD prevention and control programs. The strategies adopted
include the iodination of coarse salt, which is sold in the market
by shopkeepers and also provided free from government health clinics;
legislation requiring that salt sold in IDD-gazetted areas must be
iodised; and the use of iodinators to iodise water supplied by the
gravity-feed system to villages and boarding schools in rural areas.
The indicators used in the monitoring and evaluation of the program
include the availability of iodised salt in the market and households,
iodine levels in water supply that had been fitted with iodinators,
goitre volume measured by ultrasound, and urinary iodine excretion
among school children.

Recent
advances of vitamin E pathophysiology
Maret G Traber
Vitamin
E was discovered over 75 years ago, yet it has been only recently
recognized that human vitamin E deficiency occurs as a result of fat
malabsorption syndromes, defects in lipoprotein metabolism, and defects
in the gene for the *-tocopherol transfer protein. Although the frequency
of human vitamin E deficiency is unknown, it is likely that it is
very rare. In individuals at risk, it is clear that vitamin E supplements
should be recommended to prevent deficiency symptoms. What about their
use in normal individuals? Vitamin E supplementation in normal individuals
is quite controversial. It has been assumed that usual dietary vitamin
E intakes are adequate because human vitamin E deficiency is rare
and experimental vitamin E deficiency difficult to produce in laboratory
animals. A continuing problem in nutrition is whether nutrients have
beneficial effects when consumed in amounts in excess of those 'required'
by the body. For most vitamins, excess amounts are wasted and provide
no added benefits. Indeed, some fat soluble vitamins can be stored
and excess amounts become toxic. Antioxidant nutrients may, however,
be different. Heart disease and stroke, cancer, chronic inflammation,
impaired immune function, Alzheimer's disease: a case can be made
for the role of oxygen-free radicals in the etiology of all of these
disorders and even in aging itself. Do antioxidant nutrients counteract
the effects of free radicals and thereby ameliorate these disorders?
And if so, do large antioxidant supplements have beneficial effects
beyond 'required' amounts or even in amounts beyond those that could
be obtained from a well-balanced diet? These are questions for which
not only scientists, but also the public, are eagerly awaiting the
answers.

Food-borne
pathogens, health and role of dietary phytochemicals
Kalidas Shetty and Ronald G Labbe
Infectious diseases transmitted by food have become a major public
health concern in recent years. In the USA alone, there are an estimated
633 million cases each year. The list of responsible agents continues
to grow. In the past 20 years some dozen new pathogens that are primarily
food-borne have been identified. Fruits and vegetables, often from
the global food market, have been added to the traditional vehicles
of food-borne illness; that is, undercooked meat, poultry, seafood,
or unpasteurized milk. Such products are minimally processed and have
fewer barriers to microbial growth such as salt, sugar or preservatives.
The evolution of the epidemiology of food-borne illness requires a
rethinking of traditional, though still valid, solutions for their
prevention. Among various strategies to prevent food-borne pathogens,
use of dietary phytochemicals is promising. The major obstacle in
the use of dietary phytochemical is the consistency of phytochemicals
in different foods due to their natural genetic variation. We have
developed a novel tissue-culture-based selection strategy to isolate
elite phenolic phytochemical-producing clonal lines of species belonging
to the family Lamiaceae. Among several species we have targeted elite
clonal lines of thyme (Thymus vulgaris) and oregano (Origanum vulgare)
against Escherichia coli and Clostridium perfrigens in fresh and processed
meats. We are also evaluating high phenolic profile-containing clonal
lines of basil (Ocimum basilicum) to inhibit gastric ulcer-causing
Helicobacter pylori. Other elite lines of the members of the family
Lamiaceae, rosemary (Rosmarinus officinalis) and salvia (Salvia officinalis)
also hold promise against a wide range of food pathogens such as Salmonella
species in poultry products and Vibrio species in seafood.

Carotenoids:
more than just beta-carotene
KW Gellenbeck
Fruits and vegetables of the human diet contain many of the over 600
carotenoid pigments that have been identified in plants. Led by work
with beta-carotene, researchers have constantly been learning more
about the metabolism of these compounds in the human body. Research
work is now expanding beyond beta-carotene in an effort to understand
what happens to all the pigments found in the human diet. This discussion
briefly looks at research results on the carotenoids found in human
serum as well as the effects of supplementation. Recent confusing
results from large intervention trials with beta-carotene and lung
cancer incidence are emphasized in relation to supplementation doses
and beta-carotene source (synthetic vs. natural). The summation of
results emphasizes the importance of the broad spectrum of carotenoids
in the diet and relates to supplementation products currently being
designed for the marketplace.

Management
of obesity in non- insulin- dependent diabetes mellitus
JS Cheah
Obesity is common in non-insulin-dependent diabetes mellitus (NIDDM)
patients; in Singapore in a cohort of 314 diabetics, 44.3% were overweight.
Management of obesity in diabetics differs from that in non-diabetics
in that it is more urgent; weight maintenance is more difficult and
hypoglycaemic medication may cause weight changes. However, like in
the non-diabetic, management of obesity in the diabetic requires a
pragmatic and realistic approach. A team approach is required: the
help of a nurse educator, a dietitian, behaviour modification therapist,
exercise therapist and others are required. A detailed history, careful
physical examination and relevant investigations are required to assess
the severity of the diabetic state and to exclude an occasional underlying
cause of the obesity in the obese NIDDM patient. Weight loss is urgent
in the obese NIDDM patient, especially for those with android obesity.
There must be a reduction in energy intake. Weight loss leads to an
improvement in glucose tolerance and in insulin sensitivity, as well
as to a reduction in lipid levels and to a fall in blood pressure
in the hypertensive. Exercise is of limited short-term value measured
in terms of weight reduction, except in the younger obese NIDDM patient;
but it does allow improvement in overall metabolic control and, long-term,
is critical for preferred weight maintenance. The biguanide, Metformin,
is the hypoglycaemic drug of choice as it leads to consistent weight
reduction. The sulphonylureas may cause weight gain. Insulin should
be avoided where possible as it causes further weight gain. Other
hypoglycaemic agents include Glucobay (alpha-glucosidase inhibitor)
and Troglitazone (insulin sensitizer) which do not alter the weight.
Orlistat (lipase inhibitor) is promising as it causes reduction of
weight, blood glucose and lipid levels. Anti-obesity drugs (noradrenergic
and serotonergic agents) have modest effects on weight reduction in
the obese NIDDM patient; a widely-used preparation, Dexfenfluramine
(Adifax), has been withdrawn because of side-effects. Surgery such
as gastric plication is the last resort in treating the morbidly obese
NIDDM patient. Against this background, the institution of life-long
food and exercise habits which favour health, body composition and
fat distribution are paramount in the prevention and minimization
of expression of NIDDM. The discovery of leptin in 1994 has led to
intense research into energy homeostasis in obesity; hopefully this
will lead to better treatment of obesity in diabetics and non-diabetics.

Food
habits and beliefs in transitional societies
Anthony Worsley
This paper discusses the concept of the nutrition transition in detail.
It commences with an overview of societies which are recognised as
being in transition. The economic foundations of the transition from
traditional to modern (and post-modern societies) will be emphasised.
This will be followed by an examination of the nutrition problems
and food habits associated with transitional societies. The public
health context of such nutritional problems will also be described.
Comparisons will be made between the food beliefs and habits held
in traditional societies and those in transitional, modern and post-modern
societies. It will be argued that nutritional and medical beliefs
have come to play more extensive roles in non-traditional societies,
most probably through the mass media. Changes in personal values associated
with societal transition will be described in relation to the pursuit
of luxury foods. Finally, some of the responses to the nutritional
problems of transitional societies will be described. The essential
roles of government and non-government organisations in moderating
harmful effects of the global economy will be elucidated. It will
be argued that the success of nutrition interventions such as food-based
dietary guideline policies depend on the development of effective
national and local social organisations.

Dietary
fat consumption and non- communicable chronic diseases in China.
Chen XS MD, Wen ZM and Lin H
Fat consumption at a national level is largely determined by the economic
development of a country. Based on the data of nationwide nutrition
surveys undertaken in China in 1982 and 1992, the average intake per
capita per day of meat increased from 62.6 to 100.5 g in urban areas
and from 22.9 to 37.6 g in rural areas. The consumption per capita
per day of eggs increased from 15.5 to 29.4 g in urban areas and from
3.8 to 8.8 g in rural areas. The daily consumption of cooking oil
was 12 g in 1982 and reached 22.4 g in 1992, while the consumption
of animal fat remained stable. The average fat intake accounted for
18.1% of total energy intake in 1982 and 22.0% in 1992. The daily
fat intake of Beijing urban residents was 92.9 g per capita per day
in 1992, accounting for 32.7% of total energy intake, which was beyond
the top limit suggested by the World Health Organisation. The change
of disease patterns in Chinese people has been great during the past
two decades. The mortality rate due to cerebro-cardiovascular disease
accounted for 12.07% of deaths in 1957, and increased to 40.72% in
1994. The non-communicable chronic diseases (NCCD) accounted for approximately
70% of total deaths. Twenty-five percent of the total population and
60% of day care patients suffered from chronic diseases. The risk
factors of NCCD are increasing in China and more attention should
be given to the prevention and intervention of NCCD in the future.

Lipid
disorders in transitional societies with particular reference to triglycerides
and HDL-cholesterol
Vichai

Ratana Pakpeankitvatana and Kanika Suwan
Like Western populations, affluent urban populations in developing
countries are facing the problem of dyslipidemia, an important risk
factor of coronary heart disease. Our study of 453 affluent, urban
Thai women revealed that the prevalences of type IIa, IIb, IV and
V hyperlipoproteinemias were 32.5, 2.2, 2.4, and 0.4%, respectively.
Based on a waist-over-hip circumference ratio (WHR) of > 0.8 and
body mass index (BMI) of > 25.0 kg/m2 to indicate abdominal and
overall obesity, respectively, the prevalences of abdominal obesity,
overall obesity, and combined abdominal and overall obesity in these
women were 32.9, 5.7, and 21.2%, respectively. Both BMI and WHR in
these women had significantly positive influences on their serum triglyceride
(TG) and apo B levels, and significantly negative influences on their
serum HDL-cholesterol levels. Only BMI had a significantly positive
influence on their serum total cholesterol (TC) and LDL-cholesterol
levels but a significantly negative influence on their serum apo A-I
levels. A lipid-lowering effect of linoleic acid was shown in 101
dyslipidemic women receiving dietary intervention for 8 weeks, evidenced
by significantly negative relationships between their serum 18:2 n-6
levels and serum TC, LDL-C, TG, and apo B levels.

Nutrition
and ecosystems in Sarawak: The role of the areca nut
SS Strickland and AE Duffield
The effects of population pressure on agricultural sustainability
in the delicate tropical and subtropical ecosystems have often been
thought to explain high prevalence rates of malnutrition in rural
South-East Asia. However, recent studies in rural Sarawak suggest
that processes of modernisation have resulted in increased variations
in energy nutritional status in adults. A contributory factor may
be consumption of the areca nut (Malay pinang, of the palm Areca catechu).
This is thought to influence energy balance through effects on appetite
and resting metabolic rate. Body mass index (BMI, kg/m2) data for
325 Iban men and 438 non-pregnant Iban women, measured in 1990 and
again in 1996, have been analysed in relation to areca use, smoking
behaviour, socio-economic status, and reported morbidity. Body composition
derived from skinfold thickness measurements for 313 men and 382 women
was also analysed. The results suggest that use of areca nut is associated
with significantly lower age-related increments in BMI and percentage
body fat in women after allowing for age, smoking, reported morbidity,
and confounding socio-economic factors. Therefore, the impact of recent
economic and social development seen in rising prevalences of 'over-nutrition'
may be modulated by use of the areca nut.

Socio-economic
determinants of nutritional status of children in rural peninsular
Malaysia
Zamaliah
Mohd Marjan, Mohd Nasir Mohd Taib, Khor Geok Lin and Tee E Siong
The data presented is part of the findings from a four-year collaborative
research project between Universiti Putra Malaysia, the Institute
for Medical Research and the Ministry of Health Malaysia. The project
assessed the nutritional status of the major functional groups in
Peninsular Malaysia. Mukim Sayong and Pulau Kemiri in the District
of Kuala Kangsar, Perak were two of the subdistricts selected to represent
small rubber holdings in Peninsular Malaysia. This paper attempts
to analyse the socio-economic profile of the households and the nutritional
status of children below 9 years of age. A total of 307 households
were studied. Approximately 63% of the households were involved in
rubber activities and the majority of them were hired tappers. The
average monthly income of the households was RM467 and the income
ranged between RM30 to RM2120. Based on the per capita poverty line
income of RM84.38, it was found that 14.1% of the households earned
less than RM42.19, which can be considered as hard-core poor, while
32.7% were poor (monthly per capita income between RM42.19 and RM84.38).
Slightly more than half (52.7%) earned income above the poverty line.
The average family size was 4.5, ranging from 1 through to 16. The
majority of the heads of households (56.6%) had between 3 and 6 years
of education, and 14.5% did not receive any formal education. The
prevalence of stunting among children 05 years of age was 26%,
while 31.5% were underweight and 3.8% wasted. Among children aged
between 5 and 9 years, almost the same pattern of nutritional status
was noted. The overall percentages of stunting, underweight and wasting
among these children were 29.2%, 26.1% and 0.62%, respectively. Analysis
on nutritional status according to income level showed a noticeable
difference in the prevalence of malnutrition in children above and
below the poverty line income. The Student's t-test indicated significant
differences in weight-for-age and weight-for-height between the two
poverty line income for children below 5 years of age. Pearson's correlation
coefficient showed a significant correlation between height-for-age
with household size (r = 0.26, P < 0.05), and monthly per
capita income with weight-for-height (r = 0.25, P < 0.05). There
was a highly significant correlation between acreage of land cultivated
and weight-for-height (r = 0.42, P < 0.01), and weight-for-age
(r = 0.25, P < 0.05). The findings indicated the influence of socio-economic
factors on the nutritional status of children.

Utilisation
of wartime nutrition survival experiences
Tu Giay
In protracted and recurrent conflict, Vietnamese people have learned
to minimize food insecurity through governance, mutual social responsibility,
infrastructure development, ecological sensitivity, agricultural diversification
and emphasis on family needs and traditional food patterns. Drawing
on this experience, in 1992 a National Plan of Action for Nutrition
was devised. Its goals include increasing energy intake and reducing
childhood malnutrition.

Food
variety and biodiversity: Econutrition
Mark L Wahlqvist and Raymond L Specht
Both annual biomass production and biodiversity at any locality on
earth are continually under threat as the population of Homo sapiens
steadily increases, with the resultant pollution of atmosphere, soil
and water. Today, environmental degradation and global warming (with
its effect on evaporative aerodynamics and cellular respiration) have
increased at an alarming rate. The ABP of all terrestrial plant communities
(natural or cultivated) is slowly declining, thus reducing the energy
supply of component plants and resident animals; in turn, the biodiversity
of all the world's ecosystems, plant and animal, is threatened. The
maintenance of biodiversity is important to human health for several
reasons: (i) a varied food supply is essential to maintain the health
of the omnivorous human species; (ii) a range of diverse food sources
is necessary to safe-guard against climatic and pestilent disasters
which may affect one or more of the food sources; (iii) a diversity
of plants and animals may provide a rich source of medicinal material,
essential for the extraction of undiscovered therapeutic compounds;
(iv) intact ecosystems of indigenous plants and animals appear to
act as a buffer to the spread of invasive plants and animals, and
of pathogens and toxins, thus contributing to the health of populations
nearby; and (v) the 'spiritual' values of exploring the diversity
of plants, animals and ecosystems in an area appear to have a beneficial
effect on mental health, strengthening the feeling of 'belonging to
the landscape'. The variety of foods, their energy contents and food
values, consumed throughout the year is amenable to scientific enquiry;
as is the amount of energy expended in this collection or production.
The control and management of food production and of water supplies,
with attention to safety issues, has led to an improvement in life
expectancy for a proportion of the world's population. The question
is at what point might human health be disadvantaged by the present-day
food-production systems. In order to achieve variety in food patterns
is an agreed and internationally asserted Dietary Guideline, but the
way in which, and the extent to which, this is or needs to be achieved
is a pressing issue for biological science in general. It is a field
of enquiry which may be identified as 'Eco-nutrition'.

Characteristics
of elderly club participants of Tebet Health Center, South Jakarta
Nugroho
Abikusno and Rina K Kusumaratna
In Jakarta there currently exists an elderly healthcare program which
is implemented at community health posts, known as elderly clubs.
Recently, an elderly needs assessment was done on active participants
of such elderly clubs in Tebet, South Jakarta. Two out of six elderly
clubs were selected for the survey: namely, Cempaka (CEC, n = 45)
and Anggrek (AEC, n = 40). The need assessment consisted of demography,
health, food patterns, environment, disease, physical disability,
psycho-social status and family support systems. Approximately 85%
of the elderly club participants were female and 15% were male. There
were no significant differences between the two elderly clubs, except
that CEC had more non-Javanese participants; a higher level of education
among participants; more smokers; more women who lived with their
husbands; and more participants with hypertension, arthritis, osteoporosis,
diabetes and tooth loss. Psycho-social status of CEC was more normal
for total potential scores than was AEC. Family support for the elderly
was provided by two adult children. This rapid appraisal of the elderly
could be a useful tool for developing specific community elderly programs.

Prevalence
of rickets in Mongolia
U Tserendolgor, JT Mawson, AC MacDonald and M Oyunbileg
In order to investigate the current health and nutrition status of
mothers and children in Mongolia, a regionally stratified survey of
977 randomly sampled households was conducted during July and August
1997. The prevalence of children aged 660 months who demonstrated
one or more of three main clinical signs (i.e. rachitic rosary, Harrison's
groove and delayed closure of fontanelle) was found to be 69.8%. Although
a nationwide supplementation programme exists, caretakers reported
only 66.2% of children under 3 years of age had received at least
one vitamin D supplement in the 6 months preceding the survey. The
lack of adequate UV-B rays during the winter months (i.e. OctoberApril)
and traditional swaddling of infants for a minimum of 3 months and
a maximum of 912 months are likely to contribute to the prevalence
of rickets in Mongolia. The high prevalence of rickets in Mongolian
children is a serious public health concern. In addition to the adverse
effects on growth, development and immune function, it is probably
indicative of widespread subclinical vitamin D deficiency.
