Objectives
This study was initiated to elucidate the extent of dietary exposure of children in Korea to two pollutant metals of cadmium (Cd) and lead (Pb). Possible urban–rural difference was also examined.Methods
Food duplicate and morning spot urine samples were collected from 108 children in 4 kindergartens (KG) (1 KG in Seoul and 3 KGs in Jeju Island), as reported in a previous publication. The samples were analyzed for Cd and Pb by ICP-MS.Results
Cd and Pb in food duplicate and urine samples were distributed approximately log-normally. Geometric means for Cd and Pb in food duplicate samples were 12.4 and 5.8 μg/day, or 0.58 and 0.27 μg/kg body weight/day, respectively, and the values for Cd and Pb in urine (as observed, i.e., with no correction for urine density) were 0.91 and 1.64 μg/L, respectively. 2.41 and 0.30 μg/day of Cd and Pb (accounting for 19.5 and 5.1 %) came from boiled rice, the staple food. The levels of Cd and Pb burden among the children in the present survey were essentially the same with the levels reported for children in Pusan. The reasons for difference in the rank in Cd-D and Cd-U among the 4 KGs need further study.Conclusions
The observed levels of Cd and Pb exposure were more or less similar to what were reported for children in Pusan. No apparent urban–rural difference could be detected. 相似文献2.

Objectives
Nutrient intakes of children were surveyed at the time when a nation-wide shift took place in the Republic of Korea from agriculture-based to industrialized society. Taking advantage of the survey locations (see below), possible delay in nutritional improvement in rural areas (as compared with that in an urban area) was also examined.Methods
In total, 108 4- to 6-year-old children (boys and girls in combination) in 4 kindergartens (KGs; 1 in Seoul and 3 in Jeju Island) participated in the survey in 2003–2004. 24-h food duplicate samples were prepared by the mother of each child. Food items in each duplicate sample were separated and coded with reference to the Dietary Reference Intake for Koreans (the 2005 version). Nutrient intake of the day was estimated from the code and weight followed by summation for daily intake.Results
The children in the KG in Seoul studied were younger, and therefore were smaller in body size than those in other KGs. Thus, it was considered necessary to evaluate nutrient intake not only on a daily basis, but after adjustment for body weight. The AM daily intake of energy (protein in parenthesis) for the 108 children was 1479 kcal (55 g)/day or 69.8 kcal (2.6 g)/kg body weight/day. Evaluation by individual nutrient suggested that the intake was sufficient for almost all nutrients except for sodium and potassium. Sodium and potassium intake (2285 and 1840 mg/day, respectively) was in excess and insufficient, respectively, with potential risk of inducing hypertension later in life.Conclusions
Inter-KG difference was not remarkable and therefore urban–rural difference was not apparent. Nutrient intakes as a whole appeared to be sufficient urban and rural areas. Nevertheless, excess Na intake coupled with insufficient K intake was a common problem. 相似文献3.

Daily dietary fibre intake of toddlers living in Antwerp (Belgium) have been calculated by weighted food records with subsequent conversion using computerised food composition tables. Dietary fibre intakes were also measured by the duplicate portion technique to evaluate the intakes of total, soluble and insoluble dietary fibre. Calculated dietary fibre intake was 10 ± 3 g/d. Measured intakes of total, soluble and insoluble dietary fibre were 14.5 ± 2.8 g/d, 6.0 ± 1.9 g/d, and 8.6 ± 1.6 g/d. Values about the fibre intakes between both methods differed for 31.7%. Bread contributed for more than one third of the total dietary fibre intake. The contributions of the other food groups were 15.1% for fruits, 14.5% for starchy foods and 13.9% for vegetables. The intakes of dietary fibre from bread by the toddlers in this study could be considered as high, whilst intakes from fruits and vegetables might be increased. 相似文献

Background
Few studies have investigated the relationship between living arrangements and dietary intake among evacuees after disasters.Objectives
To examine the relationship between living arrangements and dietary intake using the data of a large-scale cohort survey of evacuees after the Great East Japan Earthquake in 2011.Methods
73,433 residents in evacuation zones responded to the Fukushima Health Management Survey questionnaire. Subjects were excluded if they did not report their living conditions or were missing more than three pieces of information about dietary intake. The data of 52,314 subjects (23,149 men and 29,165 women ≥15 years old) were used for the analyses. Evacuees' living arrangements were characterized into three categories: evacuation shelters or temporary housing, rental houses or apartments, or a relative's home or their own home. Dietary intake was characterized in terms of grains, fruits and vegetables, meat, soybean products, dairy products, and fish. Daily consumption of the third quartile (Q3) or higher for each food group was defined as ‘high consumption’. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using modified Poisson regression analyses.Results
Modified Poisson regression analyses showed that, compared with respondents living in a relative's home or their own home, the PRs and 95% CIs for the people living in rental apartments of high consumption of fruits and vegetables (non-juice), meat, soybean products, and dairy products were 0.69 (95% CI, 0.61–0.77), 0.82 (95% CI, 0.73–0.91), 0.89 (95% CI, 0.83–0.94), and 0.83 (95% CI, 0.74–0.93) respectively. The corresponding PRs and 95% CIs for people living in evacuation shelters or temporary housing were 0.83 (95% CI, 0.78–0.88), 0.90 (95% CI, 0.86–0.95), 0.94 (95% CI, 0.91–0.97), and 0.91 (95% CI, 0.86–0.96) for high consumption of fruits and vegetables (non-juice), meat, soybean products, and dairy products, respectively.Conclusion
The present study suggests that, after the earthquake, living in non-home conditions was associated with poor dietary intake of fruits and vegetables (non-juice), meat, soybean products, and dairy products, suggesting the need for early improvements in the provision of balanced meals among evacuees living in non-home conditions. 相似文献12.

We studied the association in dietary intakes and patterns between parents (aged 20–65 years) and their children (aged 2–18 years), using nationally representative data collected by the US Department of Agriculture (USDA) in the Continuing Survey of Food Intake by Individuals 1994–96. We analyzed two 24-h recall dietary data for 1061 fathers, 1230 mothers, 1370 sons and 1322 daughters. All analyses adjusted for sampling design complexity. We assessed multivariate-adjusted parent–child correlations in selected nutrients, food groups and overall dietary quality assessed using the new USDA 2005 Healthy Eating Index score (HEIn). The parent–child correlations were weak or moderate (0.20–0.33) for most intake measures. There were clear patterns of interaction with gender dyads in the intakes of calcium and dairy products (P < 0.05 for dyad × parental intake), whereby multivariate-adjusted correlations in mother–daughter or mother–child dyads were significantly stronger compared to their father–child counterparts. The reverse was true for multivariate-adjusted correlations in HEIn. Hispanics and other ethnic groups had significantly stronger resemblance than Non-Hispanic whites and blacks in soft drinks and HEIn. Resemblance in general was stronger among older children, though the reverse was true when considering agreement in HEIn's upper quintile. The influence of family income and parental education on the resemblance was small. In conclusion, parent–child dietary resemblance in the US is relatively weak, and varies by nutrients and food groups, and by the types of parent–child dyad and population groups. Factors other than parental eating behaviors seem to play an important role in affecting American young people's dietary intake. 相似文献

Objective
The objective of this study is to assess population-level trends in children's dietary intake and weight status before and after the implementation of a provincial school nutrition policy in the province of Nova Scotia, Canada.Method
Self-reported dietary behavior and nutrient intake and measured body mass index were collected as part of a population-level study with grade 5 students in 2003 (n = 5215) and 2011 (5508), prior to and following implementation of the policy. We applied random effects regression methods to assess the effect of the policy on dietary and health outcomes.Results
In 2011, students reported consuming more milk products, while there was no difference in mean consumption of vegetables and fruits in adjusted models. Adjusted regression analysis revealed a statistically significant decrease in sugar-sweetened beverage consumption. Despite significant temporal decreases in dietary energy intake and increases in diet quality, prevalence rates of overweight and obesity continued to increase.Conclusion
This population-level intervention research suggests a positive influence of school nutrition policies on diet quality, energy intake and healthy beverage consumption, and that more action beyond schools is needed to curb the increases in the prevalence of childhood obesity. 相似文献15.

A recent Cochrane review concluded that low glycaemic index (GI) diets are beneficial in glycaemic control for patients with type 2 diabetes mellitus (T2DM). There are limited UK data regarding the dietary GI in free-living adults with and without T2DM. We measured the energy and macronutrient intake and the dietary GI in a group (n = 19) of individuals with diet controlled T2DM and a group (n = 19) without diabetes, matched for age, BMI and gender. Subjects completed a three-day weighed dietary record. Patients with T2DM consumed more daily portions of wholegrains (2.3 vs. 1.1, P = 0.003), more dietary fibre (32.1 vs. 20.9 g, P < 0.001) and had a lower diet GI (53.5 vs. 57.7, P = 0.009) than subjects without T2DM. Both groups had elevated fat and salt intake and low fruit and vegetable intake, relative to current UK recommendations. CONCLUSIONS: Patients with T2DM may already consume a lower GI diet than the general population but further efforts are needed to reduce dietary GI and achieve other nutrient targets. 相似文献

The daily ganglioside intake of 19 healthy individuals was estimated based on consumption of specific foods from food records. The ganglioside content of 6 specific foods commonly consumed by healthy individuals living in the Edmonton, Alberta, Canada area was 0.51 ± 0.08 μg NANA/g (1% milk), 0.73 ± 0.09 μg NANA/g (yogurt), 0.72 ± 0.05 μg NANA/g (cheddar cheese), 1.73 ± 0.59 μg NANA/g (egg yolk), 1.70 ± 0.17 μg NANA/g (cooked ground beef), and 0.83 ± 0.32 μg NANA/g (canned tuna). The highest ganglioside content from foods analyzed, gram for gram, was found in egg yolk and cooked ground beef. The mean ganglioside intake from this group of healthy individuals was determined (i.e. <100 μg N-acetylneuraminic acid/4187 kJ daily). The findings of this study may be useful for studies investigating ganglioside concentrations of foods or usual ganglioside intake in a healthy population. 相似文献
