Body
mass index and risk of diabetes mellitus in the Asia-Pacific region
ASIA
PACIFIC COHORT STUDIES COLLABORATION
Few
prospective data from the Asia Pacific region are available relating
body mass index to the risk of diabetes. Our objective was to provide
reliable age, sex and region specific estimates of the associations
between body mass index and diabetes. Twenty-seven cohort studies
from Asia, New Zealand and Australia, including 154,989 participants,
contributed 1,244,793 person-years of follow-up. Outcome data included
a combination of incidence of diabetes (based on blood glucose measurements)
and fatal diabetes events. Hazard ratios were calculated from Cox
models, stratified by sex and cohort, and adjusted for age at risk
and smoking. During follow-up (mean = 8 years), 75 fatal diabetes
events and 242 new cases of diabetes were documented. There were continuous
positive associations between baseline body mass index and risk of
diabetes with each 2 kg/m2 lower body mass index associated with a
27% (23-30%) lower risk of diabetes. The associations were stronger
in younger age groups, and regional comparisons demonstrated slightly
stronger associations in Asian than in Australasian cohorts (P = 0.04).
This overview provides evidence of a strong continuous association
between body mass index and diabetes in the Asia Pacific region. The
results indicate considerable potential for reduction in incidence
of diabetes with population-wide lowering of body mass index in this
region..

Dietary
patterns and metabolic syndrome - a review of epidemiologic evidence
AMANDA J BAXTER, TERRY COYNE AND CHRISTINE McCLINTOCK
Metabolic
syndrome is associated with increased risk of coronary heart disease
and type 2 diabetes, and appears to be widely prevalent in both developed
and developing countries. While lifestyle modification is recommended
for management of the syndrome, the dietary pattern most beneficial
for patients is yet to be ascertained. Original research papers from
the Medline database were examined for dietary patterns that may be
associated with the syndrome. Three large-scale epidemiological studies
were found fitting our criteria. Dietary patterns high in fruit and
vegetable content were generally found to be associated with lower
prevalence of metabolic syndrome. Diet patterns with high meat intake
were frequently associated with components of metabolic syndrome,
particularly impaired glucose tolerance. High dairy intake was generally
associated with reduced risk for components of metabolic syndrome
with some inconsistency in the literature regarding risk of obesity.
Minimally processed cereals appeared to be associated with decreased
risk of metabolic syndrome, while highly processed cereals with high
glycaemic index are associated with higher risk. Fried foods were
noticeably absent from any dietary pattern associated with decreased
prevalence of metabolic syndrome. The conclusion of this review is
that no individual dietary component could be considered wholly responsible
for the association of diet with metabolic syndrome. Rather it is
the overall quality of the diet that appears to offer protection against
lifestyle disease such as metabolic syndrome. Further research is
required into conditions, such as overweight and obesity, which may
influence the effect of diet on the development of metabolic syndrome.

Natural
products and anti-inflammatory activity
GAOFENG YUAN, MARK L WAHLQVIST, GUOQING HE, MIN YANG AND DUO LI
The
aim of this review paper was to summarise some commonly available
natural products and their anti-inflammatory activity. We have collected
data from MEDLINE, Current Contents and scientific journals, which
included 92 publications. There are numerous natural products detailed
in this literature; however we have summarized a few of the most commonly
available and potent ones. In this paper, the natural products with
anti-inflammatory activity including curcumin, parthenolide, cucurbitacins,
1,8-cineole, pseudopterosins, lyprinol, bromelain, flavonoids, saponins,
marine sponge natural products and Boswellia serrata gum resin were
reviewed. Natural products play a significant role in human health
in relation to the prevention and treatment of inflammatory conditions.
Further studies are being conducted to investigate the mechanism of
action, metabolism, safety and long term side effect of these natural
products, as well as interactions between these natural products with
food and drug components.

DENG XIAO-LING, ZHANG YU-QI, LV LAI-WEN, HUANG XIN-EN AND KAZUO TAJIMA
This
paper aims to develop a data-based Semi-Quantitative Food Frequency
Questionnaire (SQFFQ) covering both urban and rural areas in the Chaoshan
region of Guangdong Province, China, for the investigation of relationships
between food intake and lifestyle-related diseases among middle-aged
Chinese. We recruited 417 subjects from the general population and
performed an assessment of the diet, using a 3-day weighed dietary
record survey. We employed contribution analysis (CA) and multiple
regression analysis (MRA) to select food items covering up to a 90%
contribution and a 0.90 R2, respectively. The total number of food
items consumed was 523 (443 in the urban and 417 in the rural population)
and the intake of 29 nutrients was calculated according to the actual
consumption by foods/recipes. The CA selected 233, 194 and 183 foods/recipes
for the combined, the urban and the rural areas, respectively, and
then 196, 157 and 160 were chosen by the MRA. Finally, 125 foods/recipes
were selected for the final questionnaire. The frequencies were classified
into eight categories and standard portion sizes were also calculated.
For adoption of the area-specific SQFFQ, Validity and reproducibility
tests are now planned to determine how the combined SQFFQ performs
in actual assessment of disease risk and benefit.

Reproducibility
and validity of a Chinese food frequency questionnaire used in Taiwan
MEEI-SHYUAN LEE, WEN-HARN PAN, KAI-LI LIU AND MEI-SHU YU
A
64-item Chinese food frequency questionnaire (FFQ) combined with open
questions on types of staples and cooking oil most frequently consumed
was designed for a prospective study in Taiwan to appraise participants'
usual intake. We examined its reproducibility and validity. The form
was administered three times at three-month intervals by face-to-face
interview to 83 senior college students majoring in nutrition, in
order to recall their usual dietary intake over the past six months.
They also completed five-day (includes both weekends) diet records
(DR) after each interview. Averaged intake levels of most nutrients
assessed by the three FFQs were slightly higher than those of 15-day
DR. Intraclass correlation coefficients for nutrient intakes assessed
by three FFQs three months apart ranged from 0.37 for saturated fat
to 0.82 for alcohol (average: 0.52). Averaged Pearson correlation
coefficients between the unadjusted and energy-adjusted nutrient intakes
measured by DR and by the third FFQ (which asked about diet during
the six months encompassing the diet records) were 0.40 and 0.35,
respectively, not including vitamins A and C. These correlations were
higher (average: 0.47) after adjusting for the daily variation of
the diet records. On average, 50% subjects were correctly classified
into the same tertiles by both methods; 11% of the subjects were misclassified
to extreme categories. These data indicate that this FFQ for Chinese-speaking
people in Taiwan is reproducible and provides a useful measure of
intake for many nutrients over a six-month period.

non-responses in mailed food frequency questionnaires in a Korean
male cancer cohort study
YOUNJHIN AHN, HEE YOUNG PAIK AND YOON-OK AHN
Item
non-responses are frequently encountered in mailed food frequency
questionnaires (FFQs) in epidemiological studies. The effects of item
non-responses in a FFQ on presumed nutrient intake and subject classifications
were examined in this study of a male cancer cohort in Korea. A semi-quantitative
FFQ was developed and mailed to adult males aged between 40 and 59
in Seoul. Among the 14,533 cohort participants, 7,647 subjects who
fully completed the FFQ initially and 216 subjects who completed the
frequency missing items at resurvey were compared. When item non-responses
were treated as not eaten, the average nutrient intakes of this group
were significantly lower than both the average intake of subjects
who fully completed at the initial survey and the average intake of
those who completed at the resurvey. Increases in nutrient intakes
during resurvey were substantively proportional to the number of items
originally omitted. Cross classifications of item non-response subjects
by nutrient intake after the initial survey and after resurvey showed
misclassification towards lower quantile. Moreover, distribution of
'never or seldom' answer of resurvey group was similar to initial
complete group. These results indicate that treating item non-responses
as not eaten introduces bias when estimating nutrient intakes or when
classifying subjects on the basis of nutrient intakes. More study
is required to determine how best to treat non-response items in FFQ..

An
Aboriginal-driven program to prevent, control and manage nutrition-related
"lifestyle" diseases including diabetes
MICHAEL
GRACEY, ERNIE BRIDGE, DAVID MARTIN, TIMOTHY JONES, RANDOLPH M SPARGO,
MARK SHEPHARD, AND ELIZABETH A DAVIS
Type
2 diabetes and other nutrition-related so-called "lifestyle"
diseases, including obesity, and cardiovascular and chronic renal
disease, are very prevalent in Australian Aboriginal people and contribute
to their high rates of chronic illness and premature mortality. An
Aboriginal-driven, community-based health protection, health promotion
and improved disease detection, management and care program was introduced
in four remote, discrete communities in the far north of Western Australia
(WA) in order to attempt to prevent these disorders through community-based
lifestyle modification. More energetic screening for early risk factors
is involved as well as early dietary and exercise interventions and
medical treatment, when indicated. Distinctive features of this program
include its Aboriginal initiatives and perspectives, committed partnerships
between the communities, the Unity of First People of Australia of
Australia (UFPA) and its carers, the communities' health care providers,
external clinical specialists, other external agencies and a locally-operated
point-of-care (POC) pathology testing capability that is conducted
by local and UFPA personnel. The POC component is quality managed
by Flinders University. These features have ensured the viability
of the program in three of the communities; the other one decided
not to continue with the program despite risks of serious long-term
health consequences. The pre-program prevalence of diabetes in screened
adults was almost 40% and in adults aged 35 years was almost 60%.
After several months of the program's operation, there have been positive
changes in knowledge about food, nutrition, exercise and disease and
altered attitudes and behaviours related to dietary and exercise patterns.
There have also been improvements in weight control and in pathology
test results relevant to the risk of subsequent development of diabetes
and cardiovascular disease.

Anthropometric,
metabolic and dietary fatty acids profiles in lean and obese diabetic
Asian Indian subjects
ARNAB
GHOSH
The
present study was aimed to study anthropometric, metabolic and dietary
fatty acids profiles among 200 (Group I: lean control, N = 80; Group
II: lean diabetic, N = 70 and Group III: obese diabetic, N = 50) Asian
Indians (aged 30 years and above) living in the eastern part of India.
Anthropometric [height, weight, waist (WC) and hip circumference]
metabolic [total cholesterol (TC), triglyceride (TG), high (HDL),
low density lipoprotein (LDL) and fasting plasma glucose (FPG)] and
dietary profiles were collected from each participant. Body mass index
(BMI), waist-hip ratio (WHR) and conicity index (CI) were subsequently
computed from anthropometric measures. An open-ended 24 h food recall
proforma consisting of three sections and in local language was used
to collect nutrient information from each participant. Daily intake
of nutrients including saturated (SFA), monounsaturated (MUFA) and
polyunsaturated fatty acids (PUFA) were estimated by adding all the
foodstuffs consumed on weekly and monthly basis. One-way ANOVA with
Scheffe's post-hoc test revealed that Group I has significantly lower
mean than both Group II and Group III for age, WC, WHR, CI, TC, TG,
LDL, FPG and total carbohydrates; Group I has significantly lower
mean than Group II only for HDL and Group I has significantly lower
mean than Group III only for BMI, total proteins and total fats. On
the other hand, Group I has significantly greater mean than both Group
II and Group III for UFA/SFA, MUFA/SFA and PUFA/SFA whereas Group
I has significantly lower mean than Group III only for trans fatty
acids and Erucic acid. Pearson's partial correlation (controlling
age and sex) analysis showed that the ratios of unsaturated fatty
acids and saturated fatty acids had significant negative association
with lipids, lipoprotein and fasting glucose. Discriminant analysis
revealed that overall 86.2% of all cases were correctly (positively)
classified in three groups using fatty acids and their ratios. In
conclusion, it seems reasonable to argue that dietary management including
dietary guidelines would be useful to retard the growing incidence
of diabetes in Indian population.

Parental
overweight as an indicator of childhood overweight: how sensitive?
KAYOUNG LEE, EUN-RYOUNG KWON, TAE-JIN PARK, MIN-SEON PARK AND CARINE
M LENDERS
This
study determined the sensitivity and specificity of parental overweight
from self-reported height and weight to identify families with overweight
school age children. A cross sectional study was conducted among 3059
parents and their children (1558 boys and 1501 girls) aged 7-12 years
in five primary schools of Busan, Korea. BMI was calculated from parental
reported height and weight and from children's measured height and
weight. Parents were considered overweight when their BMI was >25
kg/m2 (WHO, 2000). Children were considered overweight when their
BMI was >95th percentile (CDC, 2000). Prevalence of overweight
was calculated and logistic regressions were performed. The sensitivity
and specificity of parental overweight were calculated. A total of
26% (805/3059) parents were overweight. Of the families with one overweight
parent, 15% (N = 109) had an overweight child. When both parents were
overweight, 17% (N = 9) had an overweight child. After adjusting for
child's age and gender, parental education, family income, and spouse's
BMI as required, the odds of having an overweight child were 2.5 [1.8,
3.3] for one overweight parent, and 3.2 [1.4, 7.1] for both overweight
parents. While the sensitivity of one overweight parent to identify
families with overweight school age children was 44%, specificity
was 75%. The presence of both overweight parents provided a 3% sensitivity
and 98% specificity for the identification of an overweight school
age child. Although parental overweight was obtained from self-reported
weight and height in Busan (Korea), it is a practical indicator to
identify families with an overweight school age child, it has poor
sensitivity.

Body image
differences among Malay, Samoan, and Australian women
ANDREW J MCDOWELL AND MALCOLM J BOND
Comparisons of body attitudes and associated behaviours
were undertaken using Malay, Samoan, and Australian female students.
The general goal of the research was to determine the degree to which
the observed pattern of attitudes and behaviours was attributable
to culture. The specific analyses comprised an examination of group
differences using standard measures that included the Body Attitudes
Questionnaire, the Three-Factor Eating Questionnaire and detailed
questions concerning the use of diet and exercise as weight control
strategies. The main findings concerned a number of cultural differences,
particularly in relation to diet and exercise, that were evident even
with the effect of body mass index held constant. These results are
interpreted in terms of the efficacy of entrenched cultural beliefs
in protecting against introduced, more dominant, cultural values.
The Australian sample exhibited the most negative body image, although
there was some evidence that Malays and Samoans were influenced by
Western ideals of weight and shape. It is proposed that to fully understand
the differential meaning of negative body image across cultures and
the potential impact of westernisation, both within-group and between-group
differences in body size need to be acknowledged.

Differences
in nutrient intakes and physical activity levels of Japanese and Australian
Caucasian males living in Australia and Japanese males living in Japan
MASAHARU KAGAWA, YOKO SAITO, DEBORAH KERR , HAYATO
UCHIDA AND COLIN W BINNS
The
aim of the study was to determine the nutritional status and nutrient
intakes of young Japanese males living in Australia and compared with
Japanese males living in Japan and Australian Caucasian males. Four-day
dietary records were obtained from 65 Japanese living in Australia
(JA), 81 Japanese living in Japan (JJ), and 70 Australian Caucasian
males (AA) aged 18-30 years old, together with body composition and
physical activity level assessments using anthropometry and the questionnaire.
Australian males were significantly taller and heavier than the Japanese
counterparts and also showed a greater percent body fat (%BF) and
height-corrected sum of skinfolds compared with Japanese males living
in Japan (%BF: JJ = 16.6 ± 5.2, AA = 18.7 ± 5.6; height
corrected sum of skinfolds: JJ = 78.8 ± 37.3, AA = 96.0 ±
39.5) (P <0.05). A greater proportion of Australian Caucasian males
(98.6%) were involved in vigorous physical exercise than Japanese
males (JA = 72.3%; JJ = 85.2%). The JA group consumed a greater amount
of energy from protein and fat sources as well as greater calcium,
iron, dietary fibre and niacin equivalents intakes than the JJ group
(P <0.05). The results suggest that Japanese males living in Australia
consumed more energy-dense westernised diet than Japanese males living
in Japan. Because of lower physical activity level than Australian
males, consumption of energy-dense diet may increase the risk of weight
gain among Japanese males who stay in Australia for a long-term.

Physical
activity and nutritional status of children of low socioeconomic status.
Two interrelated problems: undernutrition and overweight
PAULO ROBERTO DOS SANTOS AMORIM, RICARDO CAMPOS DE FARIA, NUALA M
BYRNE AND ANDREW P HILLS
The
aim of this study was to analyse the level of habitual physical activity
(HPA) and nutritional status of children attending selected public
schools in Brazil. The sample comprised 1719 participants who ranged
in age from 11 to 14 yrs with 861 females (F) aged 12.7±1.0yr
and 858 males (M) aged 12.7±1.0yr. The short form of the International
Physical Activity Questionnaire (IPAQ) was used to measure HPA. Nutritional
status was assessed using the body mass index (BMI). Statistical analyses
included ANOVA followed by the post-hoc Tukey-test (P < 0.05) which
showed a statistically significant difference between M and F in time
spent in moderate intensity physical activity. F completed more moderate
intensity physical activity than M whereas time in vigorous physical
activities was higher in M than F. Analyses of BMI and IPAQ categorical
score using Pearson product moment correlations with subsequent Fisher
Z transformation showed values of Z = 0.49 for females and Z = 0.44
for males, indicating a low relationship between these variables.
HPA levels showed 93.7% of the M and 91.1% of the F were at least
minimally active. According to BMI values, 7.3% of the cohort was
underweight; 83.0% normal weight; 8.3% overweight and 1.3% obese.
These results demand attention, particularly for children at the lower
end of nutritional status and HPA levels due to the potential negative
impact on their growth and development. At the other end of the nutritional
spectrum, one needs to be concerned regarding the levels of excess
body weight, mainly considering the poor region in which the children
live.

Diet
composition and body mass index in Tehranian adults
PARVIN MIRMIRAN, AHMAD ESMAILLZADEH AND FEREIDOUN AZIZI
Human
studies investigating the relationship between macronutrients intake
and obesity, have failed to achieve consistent findings. This study
was undertaken to assess the relationship between macronutrients intake
and body mass index in a group of Tehranians. From 15005 participants
of the Tehran Lipid and Glucose Study, 1290 subjects aged over 10
years (565 males and 725 females) were selected randomly for dietary
survey. Anthropometric indices were measured according to standard
protocols and BMI was calculated. Dietary data were collected by trained
interviewers using two non-consecutive 24-hour dietary recalls. Data
on smoking habits, educational level and physical activity were compiled.
Under- and over-reporting of energy intake were defined as EI: BMR<1.35
and >=2.4, respectively. Calorie-adjusted amounts of macronutrients
were calculated by the residual method, following which energy intakes
from all calorie-adjusted macronutrients were simultaneously included
in the multiple regression models controlling for age, physical activity,
educational level and smoking and mutual effects of macronutrients.
Total energy intake was not included to avoid collinearity. BMI increased
with age in either gender. Controlling for confounding variables,
energy intake from fat was positively associated with BMI in males
in the 10-18, 19-24, 25-50 and 51+ year age categories (ß=0.06,
0.13, 0.33, 0.48, P<0.05 for all, respectively) and females in
the 19-24, 25-50 and 51+ age categories (ß=0.17, 0.43, 0.52,
P<0.05 for all, respectively). This relationship remained after
excluding misreporters (ß=0.06, 0.15, 0.36, 0.50 for males and
ß= 0.21, 0.46, 0.54 for females in the corresponding age categories,
respectively). The correlation of fat intake to BMI was not significant
in younger females (10-18 year). No association was seen between energy
intake from protein and carbohydrate with BMI in subjects before and
after exclusion of misreporters. In conclusion, energy from fat was
found to be independently and positively associated with obesity in
adults. No other association was observed between energy from protein
and carbohydrate with BMI

Skinfold
thickness, body fat percentage and body mass index in obese and non-obese
Indian boys
SATIPATI CHATTERJEE, PRATIMA CHATTERJEE AND AMIT BANDYOPADHYAY
Childhood
obesity is presently increasing worldwide and has created enormous
concern for researchers working in the field of obesity related diseases
with special interest in child health and development. Selected anthropometric
measurements including stature, body mass, and skinfolds are globally
accepted sensitive indicators of growth patterns and health status
of a child. The present study was therefore aimed not only at evaluating
the body mass index (BMI), skinfolds, body fat percentage (%fat) in
obese school going boys of West Bengal, India, but also aimed to compare
these data with their non-obese counterparts. Ten to sixteen year
old obese boys (N = 158) were separated from their non-obese counterparts
using the age-wise international cut-off points of BMI. Skinfolds
were measured using skinfold calipers, BMI and %fat were calculated
from standard equations. Body mass, BMI, skinfolds and %fat were significantly
(P <0.001) higher for the sample of obese boys when compared to
their non-obese counterparts. The obese group also showed progressive
age-wise increments in all recorded anthropometric parameters. Stature
(cm) showed no significant inter-group variation except in the 10
year age group (P <0.001). All data for the non-obese group were
comparable with other national and international studies, but those
collected for the obese group could not feasibly be compared because
the availability of data on obese children is limited. Current data
and prediction equations will not only serve as a reference standard,
but also be of vital clinical importance in order to identify or categorize
obese boys, and to take preventative steps to minimise serious health
problems that appear during the later part of life.

Prevalence
of obesity, overweight and underweight in a Hong Kong community: the
United Christian Nethersole Community Health Service (UCNCHS) primary
health care program 1996-1997
GARY
TC KO AND JOYCE SF TANG
The
aim of this cross-sectional observation study was to assess thoroughly
the body mass index (BMI) profile in Hong Kong Chinese and report
all categories of BMI cutoff points as suggested by the World Health
Organization (WHO). A cohort of 17242 subjects (4822 men and 12420
women) aged 15 or above from the community of Hong Kong presenting
themselves voluntarily from April 1996 to August 1997 for primary
health assessment at the Three Health Centers of the United Christian
Nethersole Community Health Service (UCNCHS). The mean age ( SD) was
51.0 16.2 years (range 15-96 years, median 49.6 years). The mean BMI
of the 17242 subjects was 23.5 3.3 kg/m2 in men and 23.0 3.7 kg/m2
in women. The BMI peaked at age 30 to 50 years in men and 50 to 70
years in women. The age-standardized prevalence of BMI 30 kg/m2 or
25 kg/m2 in Hong Kong Chinese was 3.0% in men and 3.2% in women, and
29.1% in men and 21.3% in women, respectively. For underweight, 35.9%
and 27.8% of women and 27.5% and 10.3% of men aged 15-20 and 20-30
years, respectively, had BMI <18.5 kg/m2. In conclusion, a significant
proportion of Hong Kong Chinese had a BMI 25 kg/m2. Among Hong Kong
Chinese aged <30 years, the prevalence of underweight was also
high.
Key Words: body mass index, obesity, overweight, underweight, Hong

Are
energy drinks contributing to the obesity epidemic?
ELAINE RUSH, STEPHANIE SCHULZ, VLADIMIR OBOLONKIN, DAVID SIMMONS AND
LINDSAY PLANK
The
consumption of energy drinks containing sucrose and caffeine is increasing
worldwide. Ten healthy women aged 18 to 22 years and fasted overnight
were randomly allocated to a standardised dose of sucrose either as
an "energy " drink (containing sucrose and caffeine) or
lemonade on the first day and then crossed over to the alternative
drink on a second day. For thirty minutes before and thirty minutes
after drinking oxygen consumption and carbon dioxide production were
measured in the resting subject breath-by-breath by indirect calorimetry
and the rates of carbohydrate and fat oxidation calculated. Energy
drink consumption apparently caused increased carbohydrate oxidation
(P = 0.004) and reduced lipid oxidation (P = 0.004) compared to lemonade.
The longer term effects of combined caffeine and sucrose intake, particularly
in sedentary individuals, on metabolism and body fatness needs further
examination.
Key Words: lipogenesis, caffeine, sucrose, carbonated beverage,
fat oxidation, carbohydrate oxidation.

Fruits
and vegetables, 5+ a day: Are we getting the message across?
PAULINE AL ASHFIELD-WATT
Fruit
and vegetables have important health promoting properties. The 5+
a day programme aims to promote awareness of the need to eat more
of these foods. This paper presents and discusses the results of two
surveys designed to determine the success of the 5+ a day programme
across New Zealand. Household surveys were carried out by a marketing
research company in 1999 and 2000. The 1999 questionnaire focused
on awareness and understanding of the 5+ a day campaign. The 2000
questionnaire focused on attitudes to health and on intakes of fruits
and vegetables. Data were collected from households nationwide (1999
survey N = 200, 2000 survey N = 520). Spontaneous consumer awareness
of messages promoting the need to eat more fruit and vegetables was
high. Seventy-one percent of all respondents identified the 5 servings
a day message from the 5+ a day logo regardless of whether they had
seen it before. The meaning of the hand in the logo was less clear
with only 2.5% identifying the 'serving size' element of the logo.
Fruit and vegetable intakes of respondents were influenced by demographic
factors: gender, ethnicity, education and occupation (all P = 0.05).
Positive attitude towards the relationship between fruit, vegetables
and health was influenced by similar factors and in turn affected
fruit and vegetable intakes. The 5+ a day message is well recognised
and understood. Portion size is less well understood. The 5+ a day
message promotes positive attitudes towards healthy eating which are
associated with healthier eating habits, but some groups within society
may need further attention.
Key Words: fruits, vegetables, health promotion, nutrition survey,
social marketing.

Drinking
tea is associated with lower plasma total homocysteine in older women
JONATHAN M HODGSON, AMANDA DEVINE, IAN B PUDDEY, JOHN BEILBY AND RICHARD
L PRINCE
Dietary
polyphenols are suggested to elevate plasma total homocysteine concentration
(tHcy). Although tea is rich in polyphenols, it has been associated
with lower tHcy, which may be due to its folate content. Our aims
were to investigate relationships of tea intake and 4-O-methylgallic
acid (4OMGA) - a biomarker of exposure to tea-derived polyphenols
- with tHcy in older women. In a cross-sectional study of 232 women
over 70 years of age, we measured tHcy, tea intake, 24 h urinary excretion
of 4OMGA, and red cell folate. Tea intake and 4OMGA excretion were
inversely related to tHcy. Tea intake (>2 cups) and 4OMGA excretion
above the median were associated with lower tHcy by ~1mmol/L (P <0.01).
Red cell folate was not associated with tea intake or 4OMGA excretion.
The observed lower tHcy in women with higher tea intake is consistent
in direction and magnitude with previous epidemiological studies,
but any mechanisms remain unclear.
Key Words: tea, polyphenols, homocysteine, folate, women.

Concordance
of diets and eating practices in a rural Guatemalan setting with the
cancer prevention recommendations of the World Cancer Research Fund:
Estimates from existing dietary intake
ROXANA
VALDES-RAMOS, INES CERVANTES, IVAN MENDOZA-PERDOMO, ANNIE S ANDERSON,
NOEL W SOLOMONS
To
evaluate concordance of eating practices in a rural Guatemalan setting
with the 14-point cancer prevention recommendations of the World Cancer
Research Fund/American Institute for Cancer Research. Two-hundred
sixty nine food-frequency questionnaires based on the Willett model
were analysed with respect to concordance with the recommendations,
aimed at constraining intakes of: fat, sugar, salt, red meat and alcoholic
beverages within specific ranges; restricting nutritional supplements'
use for the express purpose of avoiding cancer; maximizing the consumption
of: edible plants, especially fruits, vegetables, cereals, tubers
and legumes; achieving dietary variety and nutrient adequacy; avoiding
high-temperature cooking, and exposure to food additives, pesticides
and residues; adequately preserving perishable and fungal-prone foods;
maintaining normal body composition and regular levels of physical
activity. The study was conducted in the county seat and three hamlets
from the rural province of Santa Rosa. 214 females and 55 males were
evaluated. Daily food servings of plant origin varied from 18.2 to
99.1% (74.6 ± 10.7%). The guidelines' criteria were met by
more than 80% for total fat, red meat, ethanol, fruits and vegetables,
cereals-tubers-legumes, sugar and nutritional adequacy, whereas 80%
concordance was not met for nutritional supplements, and dietary variety.
The other variables could not be evaluated. Concordance with national
standards for micronutrient intake was not achieved most frequently
for calcium, riboflavin, and iron. Guatemalan cuisine and diet in
this rural setting has features of a cancer-protective diet, but complementary
actions must be taken, within the social and economic realities of
the region.
Key Words: total energy intake, cancer prevention, chronic disease

Lactagogue
effects of Torbangun, a Bataknese traditional cuisine
RIZAL DAMANIK , MARK L. WAHLQVIST AND N. WATTANAPENPAIBOON
Coleus
amboinicus Lour (CA) has been used as a breast milk stimulant (a lactagogue)
by Bataknese people in Indonesia for hundreds of years. However, the
traditional use of CA is not well documented, and scientific evidence
is limited to establish CA as a lactagogue. This investigation was
conducted to elucidate the effect of traditional use of CA during
the first month of lactation on quantity and quality of the breast
milk. The results collected from the study show that CA supplementation
increased breast milk production without compromising the nutritional
quality of the breast milk. Lactating women receiving CA supplementation
had a 65% increase in milk volume during the last two weeks of supplementation
(from Day 14 to Day 28). This increase was greater than that of lactating
women receiving Molocco+B12 tablets (10%) or Fenugreek seeds
(20%). The residual effects of CA supplementation were seen even after
the supplementation had ended for one month. Results of the present
study confirmed the belief and the practice amongst the Bataknese
people that CA can be used as a lactagogue in humans, and the use
of CA might be suitable for lactating women in general.

Phytochemical
intakes of the Fijian population
JIMAIMA LAKO, NAIYANA WATTANAPENPAIBOON, MARK L WAHLQVIST AND CRAIGE
TRENERRY
The
dietary intakes of major phytochemicals in Fijian population were
estimated from the consumption of 90 plant foods reported in five
major surveys conducted in Fiji from 1952 to 2001. These surveys included
the Naduri Longitudinal study, for which food intake data were collected
on four occasions in 1952, 1953, 1963 and 1994), the 1982 and 1993
National Nutritional Surveys, the 1996 Suva-Nausori Corridor cross-sectional
study, the 1999 Verata cross-sectional study, and the 2001 Fiji Food
Choice study. It was found that the Fijian population generally had
low intakes of total phenols (275 mg/day), and total flavonoids (17.5
mg/day), but high intake of total carotenoids (20 mg/day), in comparisons
with the intakes of other populations reported in literature. It has
been speculated that the change of eating patterns resulting in the
low intakes of phytochemicals may have partly contributed to the increase
in the nutritionally chronic disease morbidity and mortality among
the Fijians. It is further recommended that the traditional Fijian
food patterns with high fruits and vegetables should be revived, and
the consumption of sweet potato leaves and drumstick leaves, both
of which were rich in phytochemicals, should be promoted.
Key Words: phytochemicals, flavonoids, carotenoids, anthocyanins,
polyphenols, food intake, Fijians, Fiji.
