The study assessed the anthropometric status of 337 sub-Saharan African children aged between 3-12 years who migrated to Australia. These children were selected using a snowball sampling method stratified by age, gender and region of origin. The prevalence rates for overweight and obesity were 18.4% (95%CI: 14 - 23%) and 8.6% (95%CI: 6% -12%) respectively. The prevalence rates for the indicators of undernutrition were: wasting 4.3% (95%CI: 1.6%-9.1%), underweight 1.2% (95%CI: 0.3%-3.0%), and stunting 0.3 (95%CI: 0.0%-1.6%). Higher prevalence of overweight/obesity was associated with lower household income level, fewer siblings, lower birth weight, western African background, and single parent households (after controlling for demographic and socio-economic factors). Higher prevalence rates for underweight and wasting were associated with lower household income and shorter lengths of stay in Australia respectively. No effect was found for child's age, gender, parental education and occupation for both obesity and undernutrition indices. In conclusion, obesity and overweight are very prevalent in SSA migrant children and undernutrition, especially wasting, was also not uncommon in this target group.

The aim of the study was to determine the sensitivity and specificity of the BMI cut-off points that have been applied in the National Nutritional Survey in Japan (NNS-J) for young Japanese females. The relationship between the body mass index (BMI) and percentage body fat (%BF) of 139 young Japanese females (aged 18-27 years old) was examined using dual energy x-ray absorptiometry (DXA) and anthropometry. The sensitivity and specificity of the BMI cut-off point that has been in use in Japan was compared with the cut-off point proposed for Asia-Pacific population (the WPRO classification). The regression equation calculated for the relationship between the BMI and %BF using the DXA scan data was %BF = -15.152+2.058*BMI; R2 = 0.612, SEE = 3.66. From this equation the BMI value that corresponded with %BF of 30% was calculated to be 21.9kg/m2 (95%CI: 16.9-28.6). From the sensitivity and specificity analysis, it was found that more than 90% of Japanese females with %BF >30% were misclassified as "not obese" when the BMI value of 25kg/m2 was used to identify obese individuals. The misclassification reduced to 60% when the BMI value of 23kg/m2 was used as a cut-off point. The results indicate that the current classification used in the NNS-J may not precisely reflect the obesity status of young Japanese females and a considerable proportion of females with a large fat deposition would be misclassified as not obese. The current study shows the importance of including detailed body composition assessments to determine obesity level of individuals.

The purpose of this study was to demonstrate the relationship between body weight and HRQOL in a representative sample of nonpregnant women in reproductive age period. The data of this cross-sectional study was extracted from a survey: Manisa Demographic and Health Survey (MDHS) conducted in Manisa city in 2000. The study population of MDHS is a representative sample of 1602 reproductive (15-49) age women. World Health Organization Quality of Life Questionnaire abbreviated version (WHOQOL-BREF), which was composed of four domain factors (physical, psychological, social relations and the environment), was used to assess HRQOL. Each of four domains had a possible score ranged between 0 (poor HRQOL) and 20 (excellent HRQOL). The mean age of the women was 35.29+/- 8.19 years. Among them, 35.8 % had normal weight (BMI 18.5 to 24.9), 32.3 % were overweight (BMI 25.0 to 29.9) while 31.9 % were moderate and 3.4% were morbidly obese. After adjusting for age, level of education and co-morbid illnesses, subjects with a BMI higher than normal value, had significantly lower HRQOL scores, compared to normal-weight individuals on each of the domains, except for the environmental domain. Our results suggested that the body weight alone could negatively affect HRQOL. In other words, obesity not only increased the risk of morbidity and mortality, but also affected the perceived health and life quality negatively. In conclusion, in addition to age, socioeconomic status and co-morbid illnesses, body weight should also be controlled in studies examining HRQOL.

Evaluating the nutritional status of individuals and population groups is an important tool in public health and a feasible indicator of standards of living. The objective of this study was to determine the frequency of obesity and present nutritional status of university students of Iran University of Medical Sciences in Tehran. The survey was conducted between Oct 2004 and June 2005. The statistical population included all students from School of medicine, nursing and midwifery, health services, management, science, and rehabilitation. The method of sampling was multistage random. The sample size for the survey was 1,150 students. We used a self-administered 24h food recall questionnaire. We categorized BMI to two groups in bivariate analysis (BMI <25 kg m(-2) as obese and less than 25 kg m(-2) as non-obese). Mean BMI for all subjects was 21.7 +/- 2.9 kg m(-2). Almost 88% of the subjects were classified into a non-obese group (BMI <25 kg m(-2)). About 10% were underweight and 12.4% of the students had a BMI more than 25 kg m(-2). A significant difference was observed for BMI between males and females; 7.9% of males versus 22.5% of females had BMIs over 25. About 18% of students aged 23 years and over had BMIs over 25 versus 7.7% of students aged under 18. Intakes of fiber, pre-vitamin A, folacin and iron were significantly different between BMI groups. Intakes of these nutrients were higher in the obese students than the students with BMIs less than 25 kg m(-2). Our results indicate that about 12.4% of the students had a BMI more than 25 kg m(-2). There was a significant association between BMI, and smoking habits, age, sex, place of resident and having specific dietary regimen.

This cross-sectional study examined the relationship between alternative anthropometric indices and the nutritional and metabolic status of the Thai elderly. Four rural communities, each from the 4 main regions of Thailand were surveyed. A total of 2,324 subjects, 60 years old and over were included in the study. Mindex and Demiquet had a very strong relationship to body mass index with the r values of 0.93 and 0.88, respectively. Fat weight had the highest correlation with body mass index in older women, r = 0.94 (P< 0.001) and with Mindex, r = 0.93 (P< 0.001). In regard to anthropometric measurements, the mid-arm circumference had the strongest relationship to all three Quetelet indices, r = 0.76-0.87 (P< 0.001), while subscapular skinfold thickness performed best among skinfold measurements, r = 0.69-0.74 (P< 0.001). BMI achieved a significantly higher degree of correlation with triceps and supra-iliac skinfold thickness, mid-arm circumference and fat weight than Demiquet (P< 0.001 for all variables). The lymphocyte count was the only laboratory test that related rather well to all three Quetelet indices. All three Quetelet indices had nearly the same pattern of relationship to various nutritional parameters. The cut-off points of Mindex denoting under-nutrition, overweight and obesity I in women were 55.95, 69.55 and 75.60 kilogram/metre, respectively. At the same time, the cut-off points of Demiquet denoting under-nutrition, overweight and obesity I in men were 75.60, 93.98 and 102.16 kilogram/metre2, respectively. All this information supports the benefit of using Mindex and Demiquet as alternatives to body mass index for nutritional assessment in older Asian people, especially for the malnourished ones.

Two systems were used to classify weight status based on body mass index (BMI) of 3,178 Taiwanese adults who participated in the 1993-1996 Nutrition and Health Survey and to explore associations of BMI categories and disease. In the system proposed by the International Association for the Study of Obesity and the International Obesity Taskforce for Asian adults, overweight was associated with one disease (hypertension) and obesity was associated with four diseases: diabetes (OR = 2.66; 95% CI = 1.39-5.09; p < 0.01); gout (OR = 4.33; 95% CI = 1.92-9.75; p < 0.01); hypertension (OR = 4.92; 95% CI = 2.87-8.42; p < 0.01); thyroid disease (OR = 2.29; 95% CI = 1.12-4.67; p < 0.05). In the system devised by Taiwan Health Department for Taiwanese adults, overweight was associated with four diseases (arthritis, diabetes, gout, hypertension), and obesity was associated with three diseases: diabetes (OR = 2.11; 95% CI = 1.07-4.19; p < 0.05); gout (OR = 4.06; 95% CI = 1.77-9.28; p < 0.01); hypertension (OR = 5.28; 95% CI = 3.23-8.63; p < 0.01). The Obesity Taskforce may underestimate the association of excess weight and disease in Taiwan.

Adiponectin, which is secreted specifically by adipose tissue, has been shown to act as an anti-atherosclerotic protein. Several studies have shown that adiponectin levels are lower in individuals with obesity, diabetes and cardiovascular disease. The present study investigated relationships between serum adiponectin levels and body mass index (BMI), waist-to-hip ratio (WHR), blood pressure (BP) and lipid profiles in 300 middle-aged Korean women (mean age 50.6 +/- 6.2; BMI 25.78 +/- 3.68 kg/m(2)). The serum adiponectin level was positively associated with high density lipoprotein (HDL)-cholesterol (r = 0.29) and negatively associated with BMI, WHR, percent body fat, triglyceride (TG), systolic BP, and diastolic BP. Multivariate logistic regression analysis revealed that increasing concentrations of adiponectin were associated with lower risk of hypertension. In overall odds ratios (95% CIs) for hypertension, those in the second, third, and fourth (versus the first) quartile of adiponectin after adjustment for age were 0.59 (0.297-1.185), 0.47 (0.236 - 0.938), and 0.32 (0.16 - 0.648), respectively. Regardless of BMI, WHR and percent body fat, higher adiponectin was independently associated with a lower risk of hypertension. These findings suggest that the serum adiponectin level is decreased with atherogenic lipid phenotype including hypertriglyceridemia and low HDL-cholesterol. Furthermore, low serum adiponectin concentration may be an independent risk factor for hypertension in middle-aged Korean women.

Although risk factors for leukemia have been invastigated in numerous studies, only a few of them explain the disease etiology. Established and suspected risk factors for leukemia can be classified as familial, genetic , environmental (benzene, high dose ionizing radiation, chemotherapeutics, electromagnetic fields) and lifestyle (smoking, obesity, dietary intake). Prevention of leukemia may be possible by avoiding exposure to risk factors associated with leukemia such as smoking, benzene exposure and high dose ionizing radiation. To explain the etiology of all leukemias and develop preventive methods for the disease, future studies are needed.

Not only the incidence but the mortality of breast cancer has been steadily increasing in Korea over the last twenty years, and it became the most common female neoplasm in 2002. In fact, the increase in the rate of breast cancer mortality in Korea over the past 10 years has been higher than anywhere else in the world, and it is particularly noteworthy that more than half of the incident cases occur among those younger than 50 years of age. The rapid westernization of dietary habits and changes in reproductive behavior of Korean women presumably played a central role in this extraordinary increase in breast cancer occurrence. A large-scale multi-center case-control analysis showed that an older age, a family history of breast cancer, early menarche, late menopause, late full-term pregnancy, never-having had a breast-fed child, and postmenopausal obesity are breast cancer risk factors in Korea. Environmental and genetic factors are known to play interactive roles in human carcinogenesis and recent studies have shown that genetic polymorphisms may predispose individuals to breast cancer via gene-to-environment or gene-to-gene interactions. Thus research into genetic variation in xenobiotic metabolism, estrogen metabolism, DNA repair, cytokine metabolism, or cell cycle control may give insights into both the etiology and prevention of breast cancer. Epidemiologic evidence obtained from migrant and lifestyle change studies and investigations of main risk factors strongly suggests that breast cancer will further increase in Korea. Future predictions point to a 2- to 3-fold increase in incidence by 2020. Here, we briefly introduce health education programs and breast cancer campaigns, in the broad context of the Korean National Cancer Control Program.

Highly added sugar diets have been associated with various health problems such as dental caries, dyslipidemia, obesity and poor quality of life. Unfortunately, sugar consumption, especially sucrose, has increased continuously worldwide. The purpose of the study was to examine sources of sugar consumption and amount of added sucrose consumed in Thai undergraduate students. This study was carried out at Khon Kaen University, Thailand, between the years 2004-2005. A complete 3-day record of items and amounts of sweet consumption were obtained from 202 individuals--38 male and 164 female students. Added sucrose content of each sweetened food and drinks referred to in the record was determined by an enzymatic method. Mean intakes of sucrose were calculated from the sucrose content. The average of sucrose consumption in all subjects was 69+/-38 g/day, ranged from 4 to 182 g/day or 17 teaspoons of added sucrose per day. This amount accounted for 13.8% of total daily energy intake. There was a record of 337 kinds of sweetened foods and drinks found. The major source of added sucrose consumption was sweetened beverage, which was consumed 118 g/day averagely, or 60% of daily sugar consumption. Intake of sucrose per day in both male and female was not statistically difference, neither among different BMI groups. Intake of added sugar in the students was higher than the recommendation of the World Health Organization. These data would be helpful in a health promotion campaign aimed at a reduction of sugar consumption in Thai undergraduate students.
