Recently, choline has been associated with neurodevelopment, cognitive function and neural tube defect incidence. However, data on usual intakes are limited, and estimates of dietary intakes of choline and its metabolite betaine, are not available for New Zealanders. The objective of the present study was to determine usual intake and food sources of choline and betaine in a group of New Zealand reproductive age women. Dietary intake data were collected from a sample of 125 women, aged 18-40 years, by means of a 3-day weighed food record, and usual choline and betaine intake distributions were determined. The mean (SD) daily intakes of choline and betaine were 316 (66) mg and 178 (66) mg, respectively. The total choline intake relative to energy intake and body weight was 0.18 mg/kcal and 5.1 mg/kg, respectively. Only 16% of participants met or exceeded the Adeuate Intake (AI) for adult women of 425 mg of choline. The top five major food contributors of choline were eggs, red meat, milk, bread and chicken; and of betaine were bread, breakfast cereal, pasta, grains and root vegetables (carrots, parsnips, beetroot, swedes). Our findings contribute towards the recent emergence of published reports on the range of dietary choline and betaine intakes consumed by free-living populations. In our sample of New Zealand women, few participants were meeting or exceeding the AI level. Given recent epidemiological evidence suggesting health benefits of increased choline and betaine intakes, recommendations should be made to encourage the consumption of choline and betaine-rich foods.

In Japan, the "Food Education Basic Law" (The Basic Law on Shokuiku, food education) was enacted in 2005. The comprehensive food education programs, namely Shokuiku, aim to improve dietary practices to reduce lifestyle-related diseases. Dental caries is one of the diseases associated with inappropriate dietary habits. Thus, food education may influence the prevalence of dental caries. However, there are no data regarding the association between public based-food education and dental caries. The aim of the present study was to investigate the relationship between knowledge about comprehensive food education (Shokuiku) and dental caries experience in Japanese university students. A total of 2,184 students (1,240 men, 944 women), aged 18-20 years, were examined. They had attended the Shokuiku program while in junior/senior high school. The numbers of teeth present, and decayed, missing and filled teeth (DMFT) (dental caries experience) were recorded. Additional information was collected via a questionnaire regarding knowledge about food education, dietary habits and oral health behavior. Of the students, 315 men (20.7%) and 345 women (52.8%) reported that they know and can explain the meaning and content of the word "Shokuiku". After adjusting for potential confounding factors, subjects who did not have knowledge about Shokuiku had higher adjusted odds ratio (OR) for dental caries experience (DMFT >0) than those who had (adjusted OR, 1.23; 95% CI, 1.02-1.48; p<0.05). These observations revealed that having knowledge about comprehensive food education in university students correlates with low prevalence of dental caries.

Knowledge of the dietary intake of essential and toxic elements in fast-developing Southeast Asian countries such as Vietnam is limited. Iron and Zn deficiency in Asia is a well-known problem and is partly due to rice constituting a major part of the diet. Dietary habits are changing and there is a need to build more knowledge so authorities can give dietary recommendations. The aim of this study was to determine the total dietary intake of essential and potentially toxic elements and to assess the nutritional quality and food safety risks of the average Hanoi diet. Twenty-two foods or food groups were identified and 14 samples of each food group were collected from markets and/or supermarkets in the period 2007-2009. Water spinach, water dropwort, watercress, water mimosa and pond fish are typically produced in wastewater-fed systems. Therefore, these samples were collected both at markets and from wastewater-fed production systems. The results showed little or no risk of toxic elements from the Hanoi diet in general. Further, element contributions from wastewater-fed products were low and does not seem to constitute a problem with respect to potentially toxic elements. A comparison of the average Hanoi dietary intake of essential elements to required intakes shows that the Hanoi diet is sufficient in most elements. However, the diet may be insufficient in Ca, Cr, Fe, K and possibly Zn for which dietary diversification of biofortification might provide solutions.

The aims of this study were: 1) to explore the individual perceptions, experience and understandings of vitamin D deficiency (VDD) amongst African migrant women residing in high-rise public housing, 2) to identify the most useful sources of information about VDD among this population, and 3) to document the barriers and enablers to addressing VDD. The Health Belief Model was used to guide the study. Convenience sampling was used with women living in particular high-rise public housing. Five focus group discussions were conducted (n=30). Thematic analysis was used to code and categorise the data to develop a deeper, conceptual understanding of the issue. We found that participants were aware of VDD and could identify the impacts that VDD had on their health. Barriers to addressing VDD included the women's: 1) living conditions in Australia, 2) risk of skin cancer, and 3) cultural roles in the family. The most positive strategy for preventing and addressing VDD was peer information sharing. This study has highlighted the significant need for health promotion strategies to combat VDD in this population. Future health promoting public health strategies for this population should encompass communitybased peer education programs. This study demonstrates the critical role of qualitative inquiry in gaining a deeper understanding of VDD in a particular migrant community. It is clear that this issue requires a coordinated solution that must involve the community themselves. Health care professionals must take into consideration the multiple barriers that exist to address VDD which is a significant public health issue.

The purpose of this study was to investigate preschool children's body size and image, and analyze the impact of the primary caregiver on a child's body size and awareness in Taiwan.In a crosssectional survey, 699 preschool children and their primary caregivers participated in this study. Our study used an anonymous self-administered questionnaire, which was divided into parts A and part B. Part A was a questionnaire for the primary caregivers, including their demographic and anthropometric information, and expectation for children's body size. Part B was a two part questionnaire for children, including the children's expectation on their own body size and their consciousness in terms of body size evaluation by parents and teachers. Data was analyzed by chi-square analysis.In our study, the majority of boys and girls have a normal body size (69.0% and 64.6%, respectively). There was a significant positive correlation (p<0.05) between children and primary caregivers' body size, and a negative correlation (p<0.05) between children body size and caregivers' education level. Furthermore, we found that caregiver's satisfaction and evaluation of the children's body size had significantly affected the children's satisfaction towards their body size.Influences by the primary caregiver is an important factor that affects a preschool child's body size and body image in Taiwan. Body size evaluation by caregivers will influence the child's satisfaction level.

Purpose:

To describe the fatty acid composition of human colostrum in three different regions of China.

Methods:

Women were recruited from river/lake, coastal and inland regions of China during late pregnancy. Their diet frequency was assessed during the 34th week of pregnancy. Colostrum samples were collected between postpartum days 3 and 5. Thirty-one different fatty acids were separated and identified in colostrum.

Results:

There were significant differences among the women in the three regions with respect to food and culinary oil consumption patterns. The mean±SD fat content (g/100 g) of colostrum from river/lake, coastal and inland regions was 2.17±1.26, 2.50±1.39 and 2.68±1.26, respectively (p=0.265, adjusted by pregnant women's age). The main saturated, monounsaturated, n-6 polyunsaturated and n-3 polyunsaturated fatty acids in colostrum were 16:0, 18:1n9, 18:2n6 and 18:3n3, respectively. Colostrum from river/lake region had the lowest composition of total SFA and of total n-6 PUFA and the highest composition of total MUFA and of total n-3 PUFA. The amount of DHA (22:6n3) in colostrum (mean±SD, % wt/wt) was 0.51±0.18, 0.52±0.20 and 0.35±0.13 in the river/lake, coastal and inland regions, respectively (p=0.0002, adjusted by pregnant women's age). Frequency of maternal marine fish intake during the late pregnancy was positively correlated with DHA in colostrum (r=0.203, p=0.040).

Conclusions:

The fatty acid composition of colostrum differs across geographical regions in China, which may be related to differences in maternal dietary pattern.

The aim of the present study was to clarify clinical factors in low birth weight infants and their mothers associated with exclusive breastfeeding at both neonatal intensive care unit (NICU) discharge and the start of complementary feeding. One hundred and fifteen low birth weight children and 98 mothers attending the follow-up clinic of two tertiary NICUs in Nara prefecture (Japan), between June and September, 2011, were enrolled. The relationship between the feeding categories at NICU discharge or the start of complementary feeding, and clinical factors of the mothers and low birth weight infants collected by either their charts or a face-to-face interview was analyzed. The prevalence of exclusive breastfeeding was 22.6% at NICU discharge, and 15.7% at the start of complementary feeding. In logistic analysis, exclusive breastfeeding at NICU discharge was associated with mother's younger age at delivery and an earlier start of oral nutrition. Among 26 exclusively breast-fed infants at NICU discharge, fifteen infants (57.7%) were still being exclusively breast-fed at the start of complementary feeding. In low birth weight infants, a shorter stay at NICU and an earlier start of oral nutrition were associated factors with exclusive breastfeeding at the start of complementary feeding. None of maternal factors were found to be associated with exclusive breastfeeding at the start of complementary feeding. Conclusively, starting of oral nutrition as early as possible is thought to be crucial for introducing exclusive breastfeeding in low birth weight infants both at NICU discharge and the start of complementary feeding.

This study aimed to translate and validate a Chinese (simplified) version of the Iowa Infant Feeding Attitude Scale (IIFAS) and compare the infant feeding attitudes of Chinese mothers living in Perth Australia and in Chengdu P.R. China. A survey was undertaken on 200 Chinese mothers living in Perth and 1620 mothers living in Chengdu. The simplified Chinese version of IIFAS had a moderate level of internal consistency with a Cronbach's alpha of 0.69 for mothers in Australia and 0.55 for mothers in China. The mean IIFAS scores in both country groups lay in the range of 'neutral breastfeeding attitudes'. Higher IIFAS scores were significantly associated with the likelihood of both breastfeeding initiation (OR: 3.85; CI: 2.49-5.96; p<0.001) and longer (>=8 months) breastfeeding duration (OR: 2.52; CI: 1.87-3.40; p<0.001). Chinese mothers in Perth (mean IIFAS score=60.0±6.3) tended to have more positive attitudes towards breastfeeding than mothers in Chengdu (mean IIFAS score=57.7±5.1, p<0.001), and had a longer duration of 'any breastfeeding' (10.0±6.2 months in Perth compared to 7.4±4.3 months in Chengdu, p<0.001). In conclusion, higher scores on the IIFAS in simplified Chinese are associated with breastfeeding initiation and duration in Chinese populations.

This study describes Japanese mothers' knowledge and attitudes towards breastfeeding using the Iowa Infant Feeding Attitudes Scale (IIFAS). A cross-sectional survey of 1,612 mothers was conducted in Japan in 2007. The participants were recruited at the free health checks conducted for infants at 18 months of age. The survey was self-administered using the Japanese version of the IIFAS. Descriptive statistics were used to summarise sample characteristics and IIFAS score followed by multiple logistic regression to identify association between total IIFAS score and breastfeeding duration. While the IIFAS showed that the majority recognized some benefits of breastfeeding, their overall knowledge and attitudes towards breastfeeding were neutral and more positive towards the use of infant formula. It is important to provide accurate prenatal education that focuses on methods and long-term benefits of infant feeding to mothers, family and health professionals.

Hair mineral analysis using an X-ray fluorescence spectrometer as a method of estimating body fat percentage (BF%) was investigated. Body fat percentage of 24 healthy Japanese, aged 20-27 years, was measured using a hand-held impedance analyzer (BF%IMP). X-ray (Kα-ray) intensities of sulfur, chlorine, potassium, calcium, titanium, and iron (Fe) in hair were measured using an X-ray fluorescence spectrometer. Body fat percentage was also measured using a Hologic whole body dual energy X-ray absorptiometer (BF%DXA) in nine subjects selected from the above 24 subjects based on their BF%IMP. Correlations of the two BF%s with Fe-Kα were significant (BFIMP: r = 0.60 n = 24, p<0.01; BFDXA: r = 0.67 n = 9, p<0.05). The mean (±SD) biases (measured minus estimated using multiple regression equations by Fe-Kα) for BF%IMP and BF%DXA were 2.97 ± 2.25% and 1.77 ± 1.33%, respectively. The SEEs for the two equations for BF%IMP and for BF%DXA were less than 4%. These results suggest that Fe-Kα may be a predictor of body fat percentage. However, the subjects were few and only Japanese in their twenties, so that further investigation is needed for methodological generalization.
