ABSTRACT
Objective @#To examine the association between dietary patterns during pregnancy and gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the establishment of healthy and balanced dietary patterns and reducing the prevalence of GDM.@*Methods@#Pregnant women who underwent oral glucose tolerance tests in Hangzhou Obstetrics and Gynecological Hospital from 2020 to 2021 were enrolled, and their demographic information were collected using questionnaires. Pregnant women's diets during the past three months were collected using Food Frequency Questionnaires (FFQs), and dietary patterns were extracted using principal component analysis. In addition, the association between dietary patterns and risk of GDM was examined using a multivariable logistic regression model.@*Results@# A total of 1 689 pregnant women were included, with a median age of 28.53 (interquartile range, 2.47) years and a median gestational age of 26.00 (interquartile range, 2.00) weeks. Five dietary patterns were identified according to pregnant women's types of diets, including meat-based diets, dessert-fruit-refined grain diets, plant-based diets, eggs-milk-nut diets and whole-grain diets, with a cumulative contribution rate of 58.76%. The prevalence of GDM was 24.57% (415 cases) among the study subjects. Multivariable logistic regression analysis showed that pregnant women with scores in the highest quartile (Q4) of the meat-based diets had an increased risk of GDM (OR=1.372, 95%CI: 1.043-2.055) relative to those with scores in the lowest quartile (Q1), and pregnant women with Q4 scores of the dessert-fruit-refined grain diets had an increased risk of GDM (OR=1.743, 95%CI: 1.397-2.432) relative to those with Q1 scores, while pregnant women with Q4 scores of the plant-based diets had a reduced risk of GDM (OR=0.382, 95%CI: 0.346-0.613) relative to those with Q1 scores.@*Conclusion@#A plant-based dietary pattern may reduce the risk of GDM, while meat-based and dessert-fruit-refined grain dietary patterns may increase the risk of GDM.
ABSTRACT
Background Global dietary magnesium insufficiency is widespread and seriously harmful to human health. There are few studies on dietary magnesium intake in China, and associated dietary intervention lacks scientific support. Objective To explore the dietary magnesium intake level and food sources of Chinese adults aged 18-64 in 2018, and to identify the problems of dietary magnesium intake. Methods A total of 9181 residents in the 2018 "China Health and Nutrition Survey" were selected as the study subjects. Types and intake of food collected from consecutive 3-day 24-hour dietary recalls and by household condiment weighing and counting method. The average daily dietary magnesium intake and the composition of main food sources were calculated using the food composition table. Multiple logistic regression was used to analyze the relationship between socioeconomic factors and insufficient dietary magnesium intake. Results In 2018, the daily intake of magnesium in P50 (P25, P75) of adults aged 18-64 in 15 provinces (autonomous regions and municipalities) of China was 252.28 (196.25, 326.27) mg. The proportion of residents with insufficient dietary magnesium intake was 60.9%. The proportions of women, adults aged 18-49, urban residents, southern region residents, and western regions residents with insufficient dietary magnesium intake were 66.4%, 63.4%, 62.4%, 65.2%, and 68.3%, respectively. The results of multiple logistic regression analysis showed that the risks of insufficient dietary magnesium intake were 64.6%, 24.6%, and 43.6% higher in women, urban residents, and southern region residents than those in men, rural residents, and northern region residents, respectively (OR=1.646, 95%CI: 1.509-1.794; OR=1.246, 95%CI: 1.126-1.379; OR=1.436, 95%CI: 1.311-1.573); the risk of insufficient dietary magnesium intake in residents aged 50-64 was 15.7% lower than that in residents aged 18-49 (OR=0.843, 95%CI: 0.771-0.921); the risks of insufficient magnesium intake in residents in middle and western areas were 1.202 times and 1.590 times of that in residents in eastern area (OR=1.202, 95%CI: 1.079-1.340; OR=1.590, 95%CI: 1.424-1.776). The effect of education level and income level on magnesium intake insufficiency was not observed (P>0.05). In addition, 41.4% of dietary magnesium of the subjects came from cereals and products (ranking first in food sources), and only 2.4% from dark vegetables with rich magnesium content (ranking sixth place). The top six dietary magnesium sources of men and women were the same. The proportion of dietary magnesium from cereals and products was 6.3% higher in rural residents than in urban residents, and 9.3% higher in residents living in northern regions than those in southern regions. The proportion of dietary magnesium from livestock meat and products was 1.3% higher in the 18-49 age group than in the 50-64 age group, 0.9% higher in urban residents than in rural residents, and 1.6% higher in western region residents than in eastern region residents. Conclusion The dietary magnesium intake of Chinese residents is generally insufficient, and the source of dietary magnesium is irrational. Women, residents aged 18-49, residents in southern, middle, and western areas are high-risk populations of dietary magnesium insufficiency. Chinese residents are encouraged to eat more dark vegetables and whole grain food; women should improve their dietary quality and intake diverse magnesium-rich food; southern region residents and urban residents should increase the intake of whole grains and avoid over refining food; residents aged 18-49, urban residents, and those in western regions should adjust their dietary structure and reduce meat intake.
ABSTRACT
ObjectiveTo provide basic data of daily dietary intake from various food categories as well as in different regions, seasons, genders, and age groups in Shanghai residents aged 15 and over. MethodsMultistage stratified proportional probability sampling (PPS) was used to extract the samples, and food frequency questionnaire (FFQ) was used to investigate the dietary intake of the subjects in four seasons from 2012 to 2013. The weighted statistical analysis of the samples comprehensively considered the sampling design weights, the stratified adjustment weights, and the non-response adjustment weights. ResultsThe total daily dietary intake (excluding drinking water) of residents aged 15 years and above was 1 174.71 g, and the highest three daily dietary intake categories were cereals (252.31 g), vegetables (205.36 g) and fruits (141.00 g). The total daily dietary intake of the residents in the urban area, the suburban area and the rural area was 1 209.15 g,1 172.27 g and 948.50 g, respectively, and the total daily dietary intake in the outer suburb area was significantly lower than that in other areas (F=74.12,P<0.001). The total daily dietary intake in different seasons was 1 232.47 g in spring, 1 166.80 g in summer, 1 241.15 g in autumn and 1 088.83 g in winter, respectively. The total daily dietary intake in winter was lower than that in other seasons (F=15.96,P<0.001). Fruits and beverages intake showed apparent seasonality. The total daily dietary intake in male and female residents was 1 234.03 g and 1 112.32 g, respectively, and the total daily dietary intake of male was higher than that of female (F=78.59,P<0.001). The total daily dietary intake of residents in different age groups was 1 218.64 g for 15‒44 years old, 1 141.27 g for 45‒59 years old, and 1 064.54 g for 60 years old and above (F=20.28,P<0.001). ConclusionThe daily intake of cereals, livestock and poultry meat, aquatic products, eggs and edible oil is relatively balanced, but the daily intake of vegetables, fruits and milk is relatively insufficient for the residents aged 15 years and above in Shanghai. The daily intake of different food types shows distinguishable characteristics in urban and rural areas, seasons, age groups and genders.
ABSTRACT
PURPOSE@#The purpose of this study was to evaluate the reproducibility and validity of a short food frequency questionnaire (FFQ) for food group intake in Japan, the reproducibility and partial validity of which were previously confirmed for nutrients.@*METHODS@#A total of 288 middle-aged healthy volunteers from 11 different areas of Japan provided nonconsecutive 3-day weighed dietary records (DRs) at 3-month intervals over four seasons. We evaluated reproducibility based on the first (FFQ1) and second (FFQ2) questionnaires and their validity against the DRs by comparing the intake of 20 food groups. Spearman's rank correlation coefficients (SRs) were calculated between energy-adjusted intake from the FFQs and that from the DRs.@*RESULTS@#The intake of 20 food groups estimated from the two FFQs was mostly equivalent. The median energy-adjusted SRs between the FFQ1 and FFQ2 were 0.61 (range 0.38-0.86) for men and 0.66 (0.45-0.84) for women. For validity, the median de-attenuated SRs between DRs and the FFQ1 were 0.51 (0.17-0.76) for men and 0.47 (0.23-0.77) for women. Compared with the DRs, the proportion of cross-classification into exact plus adjacent quintiles with the FFQ1 ranged from 58 to 86% in men and from 57 to 86% in women. According to the robust Z scores and the Bland-Altman plot graphs, the underestimation errors in the FFQ1 tended to be greater in individuals with high mean levels of consumption for meat for men and for other vegetables for both men and women.@*CONCLUSION@#The FFQ demonstrated high reproducibility and reasonable validity for food group intake. This questionnaire is short and remains appropriate for identifying associations between diet and health/disease among adults in Japan.

Aims: Investigate the influence of the nutrition knowledge and nutritional status in the assessing energy intake underreporting. Methodology: It’s a cross-sectional study in 52 adults treated in an ambulatory. The nutritional knowledge was measured through the Nutritional Knowledge Scale. The anthropometric data analyzed were: waist circumference, height and weight. The food consumption was checked by three recalls of 24 hours. The resting metabolic rate was calculated by the Mifflin’s formula, and the assessing energy intake underreporting was calculated after Goldberg’s formula. Statistical analysis was performed by the “Bioestat 5.0” program and the Chi Square test for trend was used to evaluate the association between variables (p≤0,05). Results: The studied group showed an average age of 38,90±9,52. The assessing energy intake underreporting was noted in 92,3% of the sample. It was observed that the average energy intake related (1583,27±575,29 Kcal) was less than the average of the resting metabolic rate (1802,71±227,02 Kcal). Higher values of IMC (A = 0,153; p = 0,85) and in waist circumference (A = 2,769; p = 0,05) were associated with the increase of the assessing energy intake underreporting. In the other hand, there was a decreasing tendency (A = - 0,384; p = 0,750) in the association between energetic underreporting and nutritional knowledge. Conclusion: It was observed a higher tendency of assessing energy intake underreporting between individuals with higher IMC and waist circumference and lower nutritional knowledge.
ABSTRACT
Objective To investigate the characteristics of diet for infants in relatively poor counties in different cities of Yunnan and to provide a reference for carrying out educational consultation in the future by comparing and analyzing the data of infant diet in those areas.Methods Based on the GDP and habits of diet,the characteristics of infants' diet was investigated and analyzed in four counties including Yiliang in Zhaotong,Jianchuan in Dali,Lushui in Nujiang,and Mojiang in Puer,with low income and different habits of diet.Results No difference was found among people who fed the infants in terms of sex,age groups,feeding relationship and degree of education except for one fact that the feeding rate of parents in Jianchuan county was lower than that in Yiliang county.Based on the standard intake of nutrient in Chinese people,the intake of infant protein in 6-12 months achieved Chinese standard in four counties.Energy,fat and carbohydrates were lower than the standard (P<O.05).Apart from the fact that energy,protein,fat and carbohydrates were lower in Yiliang county,no significant difference was found among four counties.The intake of protein and carbohydrates for infants in 13-24 months achieved Chinese standard in the four counties,but energy and fat were lower than the standard.The carbohydrates of infants in 6-24 months was normal and the fat was lower compared with acceptable macro nutrient distribution ranges.The intake of carbohydrates,fat and protein were similar among four counties.Conclusion The diet composition and the nutrient condition for infants are poor in four counties.Health education of nutrition for infants is needed in those areas.
ABSTRACT
Objective To assess the differences in nutrient composition by chemical analysis method and weighing method,A corps of armed police forces daily dietary nutrient intakes were investigated in Tianjin,to understand the status of the actual intakes of dietary nutrient.Methods A dietary survey was performed using the weighing method and with ref-erence to China food composition database in 2002.The intake of each nutrient was calculated through chemical analysis;Nutritional analysis was used in the collection of duplicate food portions during the dietary survey.Results For most of the main dietary nutrients(protein,fat and carbohydrates),minerals (Na,K,Mg,Ca,Zn,Cu and Se)and vitamins (β-car-otene,vitamin E,thiamine,riboflavin,vitamin C,niacin,and vitamin A),the calculated values of intakes were found to exceed those obtained via chemical analysis.Conclusion Differences of the two methods of dietary survey were ultimately due to the analysed values were below the calculated ones.So it is necessary to improve methods of food storage and trans-portation in order to obtain adequate nutrition and to improve the health of troops.

ABSTRACT
Objective To study the changes of iodine source and the nutritional status of iodine after termination of iodized salt supply in the areas with different water iodine concentrations in Shanxi province,in order to provide scientific bases for developing strategies on control and prevention of iodine deficiency disorders,and to study the cut-off value of water iodine level where iodized salt supply should be stopped.Methods In 2010 in Shanxi province,6 villages with 100% of non-iodized salt consumption rate were selected as the survey spots based on the iodine concentration in drinking water of 0-,50-,100-,150-,300-,≥500 μg/L.Villages'iodized salt supply was terminated thoroughly.In each village,20 children aged 8 to 10 were selected.At the same time,women of childbearing age 18 to 50 years old and adult men aged 18 to 60 were selected from the same families as the children.Diet surveys were conducted by the method of 3 days recall on all subjects.Drinking water samples,staple foods,supplementary foods and urinary samples of all subjects were collected and the iodine concentration was determined by arsenic-cerium catalytic spectrophotometry.Results ①In the villages of water iodine 25.9,70.6 μg/L,the medians urinary iodine of children,women and men were all ranged from 100 to 199 μg/L,which meant their iodine nutrition levels were appropriate.In the village of water iodine 109.0 μg/L,the medians urinary iodine of children,women and men were all ranged from 200 to 299 μg/L,which meant their iodine nutrition levels were more than appropriate.In the villages of water iodine 225.8,430.0,581.2 μg/L,the medians urinary iodine of children,women and men were all ≥ 300 μg/L,which meant their iodine nutrition levels were too high.②)In all the 6 villages,the intaking amount of iodine met and exceeded the standard recommended intake of dietary iodine by ICCIDD/UNICEF/WHO (8 to 10-year-old children ≥ 120 μg/d,women of childbearing age and adult men ≥ 150 μg/d).But in the village of water iodine 581.2 μg/L,the iodine intake was exceeded the daily maximum safe intake (children aged 8 to 10 ≤800 μg/d,women of childbearing age and adult man ≤ 1000 μg/d).③The amount of iodine ingestion from drinking water was increased with the water content of iodine.When water iodine exceeded 100 μg/L,the amount of iodine ingestion from drinking water was higher than from food intaking,and became a main resource of iodine in the human body.Conclusions In the counties of iodine concentration in drinking water above 100 μg/L in high iodine areas of Shanxi province,the water iodine becomes the most important source of iodine,and iodine nutritional level is more than appropriate or possible excess.It is recommended that in areas of high water iodine of Shanxi province,the standard cut-point of water iodine value is set to 100 μg/L.
ABSTRACT
To study the status of diet and nutrition in Uyghur families with maturity onset diabetes of young (MODY).Four MODY families were composed of four generations of Uyghur with 50 members collected from Kashgar,Shanshan,and Ili regions of Xinjiang Uyghur Autonomous Region.A dietary survey with a semi-quantitative food frequency questionnaire was conducted.According to the sex and different intensities of physical activity,the nutrient intake was calculated by nutrition calculator software,and the results were compared with recommended nutrients intake(RNI).Cereals,livestock,and poultry meat,being the main food stuff in Uyghur MODY families,accounted for 54.11% and 13.87% of total energy respectively,while fruit,fish,and shrimps were seldom taken,and accounted for 0.41% and 0.26% of total energy respectively.Carbohydrate,protein,and fat accounted for 55.0%,16.7%,and 28.4% of total energy intake respectively,within the scope of the RNI for diabetes suggested by both Chinese Diabetes Society and the American Diabetes Association.The total energy and all three major nutrients were excessively taken by subjects of different genders and different intensities physical activity from Uyghur MODY families in Xinjiang.Uyghur diets lead to excessive calorie intake in the Uyghur MODY family members.The Health education of Uyghur language and text should be strengthened,so as to improve the scientific dietary knowledge.

Esta tese é composta por quatro artigos que permitiram avaliar o impacto do consumo de alimentos fora do domicílio na dieta e no peso corporal da população brasileira. O primeiro artigo revisou de forma sistemática as evidências científicas da associação entre alimentação fora do domicílio e peso corporal com abordagem crítica dos artigos publicados na literatura. Foram avaliados 28 artigos e os resultados sugeriram uma associação positiva entre o consumo de alimentos fora do domicílio e o ganho de peso. A revisão mostrou que uma das limitações nessa área é a ausência de padronização nas definições e métodos de avaliação do consumo de alimentos fora do domicílio. Para o desenvolvimento dos demais artigos, utilizou-se dados do Inquérito Nacional de Alimentação (INA) do Brasil, uma subamostra da Pesquisa de Orçamentos Familiares (POF) 2008-2009, com o objetivo de caracterizar o consumo de alimentos fora do domicílio da população brasileira (artigo 2) e investigar a associação entre alimentação fora do domicílio e ingestão total de energia (artigo 3) e peso corporal (artigo 4). As análises foram realizadas com os dados de consumo de alimentos coletados por meio de registro alimentar de 34.003 indivíduos acima de 10 anos em dois dias não-consecutivos. Os registros incluíram descrição detalhada dos alimentos e quantidade consumida, tipo de preparação, horário e local de consumo (dentro ou fora do domicílio). Alimentação fora do domicílio foi definida como todo alimento adquirido e consumido fora de casa. O primeiro dia de registro foi utilizado nas análises, considerando o peso amostral específico do INA e o efeito do desenho amostral. O consumo de alimentos fora do domicílio no Brasil foi reportado por 40% dos entrevistados; diminuiu com a idade e aumentou com a renda em todas as regiões brasileiras; foi maior entre os homens e na área urbana. Os grupos de alimentos com maior percentual de consumo fora de casa foram bebidas alcoólicas, salgadinhos fritos ...
This thesis is composed by four articles that focused on the impact of food consumed away from home on the diet and body weight of the Brazilian population. The first article is a systematic review of the scientific evidence of the association between food away from home and body weight with a quality assessment of published articles in scientific literature. We evaluated 28 articles and results suggested a positive association between the consumption of food away from home and weight gain. The review showed that one of the limitations in this area is the lack of standard definition and methods to assess away-from-home eating. For the other articles, data from the Brazilian National Dietary Survey (NDS) conducted along with the Household Budget Survey (HBS) 2008-2009 were used to characterize the consumption of food away from home (article 2); to investigate the association between away-from-home food consumption and total energy intake (article 3), and body weight (article 4). Analyses were conducted with 34,003 individuals over 10 years old with data on food intake collected through food records in two non-consecutive days. The records included detailed description of the food and the amount consumed, type of preparation, and time and place of consumption (at home or away from home). Away-from-home food was defined as all foods purchased and consumed outside the home. The first day of record was used in the analyses, taking into account the sample weight of NDS and the sample design. The consumption of food away from home in Brazil was reported by 40% of the respondents; decreased with age and increased with income in all Brazilian regions; it was higher among men and in urban areas. The groups with the highest percentage of food consumption outside the home were alcoholic beverages, baked and deep-fried snacks, pizza, soft drinks and sandwiches. Among those living in urban areas (n=25,753), the mean energy intake from away-from-home food was 337 kcal ...

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin B6, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

The objective of this study was to examine agreement between parental preferences and self-reported food intake in Chilean children. In 2008,152 pairs, of 8 to 13 year old schoolchildren and their parents in Santiago were surveyed. Children self-reported their frequency of consumption of foods from various food groups. Parents reported how often they preferred their children to consume foods from these same food groups. Children reported consuming more sweets, high-calorie snacks, and fruit, and fewer grains than their parents reported preferring them to consume. Girls, 10 and 11 year olds, and children who watched television and used the computer for less than 2 hours per day had dietary patterns most closely aligned with their parents' reported preferences. Children 's dietary reports generally follow parental preferences. Intervention programs should include programs that facilitate parental guidance and encourage children to make healthy food choices at home and in school.
Se estudia concordancia entre preferencias de padres y auto-reporte de niños chilenos en consumo de alimentos. En 2008, se encuestaron 152 escolares ente 8 y 13 años de edad y sus padres, en Santiago, Chile. Los niños reportaron frecuencia de consumo de diferentes grupos de alimentos y los padres, frecuencia con que prefieren que sus hijos los consuman. Los niños informaron mayor consumo de dulces, colaciones altas en calorías y frutas y menor consumo de cereales, que lo declarado por sus padres. Los patrones alimentarios más estrechamente alineados con lo reportado por los padres se observan en: niñas; edades entre 10 y 11 años; ver televisión y utilizar computador menos de 2 horas diarias. En general, lo reportado por niños sigue los patrones de los padres. Programas de intervención debieran incluir guía a padres y estimulo a niños para elegir opciones alimentarias saludables en el hogar y en la escuela.

Objective To investigate the serum levels and dietary intakes of copper, iron, and zinc among adult residents in Dahongshan copper mine area of Yunnan Province in China. Methods Serum levels of copper, iron, and zinc were measured by atomic absorption spectrometry among 180 subjects collected randomly from Dahongshan mine area, among which 171 samples were valid. Dietary intakes of copper, iron, and zinc of 60adults collected randomly from these 180 subjects were detected by chemical analysis. Results Serum levels of copper, iron, and zinc concentrations of 171 valid samples were (0.90±0.18), (1.25±0.93) , and (0.75±0. 28) mg/L, respectively. Serum copper was negatively correlated with serum iron (r = - 0. 26, P < 0. 001). Serum copper was positively correlated with age (r = 0. 25, P < 0. 001). Females had significantly higher serum copper than males (P=0.011). The dietary intakes of copper, iron, and zinc among these 60 subjects were (1.74±1.09),(16.29±10.73), and (7.56±3.38) mg/d, respectively, in which females had significantly lower dietary intakes than nales (all P < 0. 05). Significant regional differences were observed both in serum levels and dietary intakes of copper, iron, and zinc. Conclusions The average serum levels of copper and iron are normal among adult residents in Dahongshan copper mine area, while the average serum zinc level is low. Dietary intakes of these three minerals do not exceed tolerable upper intake levels, and are low in some subjects.
ABSTRACT
Objective To determine the relationship between zinc and nutritional status or immunity in patients with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis (CAPD). Methods Forty-five stable CAPD patients undergoing peritoneal dialysis were enrolled in this study. The dietary zinc intake and serum zinc levels were investigated, and the results were compared with the gender- and age-matched healthy populations (n = 45). The relationship between dietary zinc intake and serum zinc levels and subjective global assessment (SGA) score, blood cell counts, serum albumin (ALB), prealbumin (PA), C-reactive protein (CRP),and lymphocyte subsets were analyzed. Results The percentages of inadequate dietary zinc intake (P= 0. 007)and low blood zinc (P = 0. 036) were significantly higher in CAPD patients than in healthy group. CD8 levels were significantly lower (P = 0. 000) while CD4/CD8 ratio was significantly higher (P = 0. 033) in CAPD patients than in healthy group. In CAPD patients, correlation analysis showed that dietary zinc intake was significantly correlated with serum prealbumin levels (r = 0. 577, P = 0. 000), but was negatively correlated with SGA score (r = - 0.354,P = 0. 015) and CRP (r = - 0.354, P = 0. 015); however, it was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Serum zinc level was significantly positively correlated with hemoglobin (r= 0. 411, P=0.005), hematocrit (r=0.345, P=0.023), WBC (r=0.318, P=0.035), SGA score (r=0.417, P=0. 005), and CRP (r=0.342, P = 0. 027), but was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Conclusions Zinc deficiency is common among patients with CAPD. Adequate dietary zinc intake can facilitate protein synthesis and improve the overall nutritional status. High serum zinc concentrations are beneficial for the synthesis of hemoglobin and the improvement of anemia.
ABSTRACT
This study was conducted to examine the usefulness of adding final probing step (step3) in dietary assessment by 24-hour recall method among Korean adults. One-hundred fifty five adults (37 males and 118 females) above 30 years of age who visited hospitals for health examination were recruited at three hospitals in Korea. One day dietary intake was obtained using 24-hour recall method from each subject. Dietary interview was conducted in 3 steps, (1) quick list of foods eaten during the previous day, (2) detailed information of all the foods eaten, (3) the final probing for any items forgotten. Items added at the step3 were identified and contributions of energy and nutrient intakes were calculated. The average duration of interview was 10.5 min, and time spent for each step was 4.12 minute for step 1, 5.62 minute for step 2, and 38 second for step 3. The average number of dishes reported by the subjects added at the step 3 was 2.2. (Males = 2.6, Females = 1.6) Frequently reported dishes in the step 3 were Beverage, Tea, alcohol (37.1%) and Fruits (31.8%). From mean total energy intake of 1,589 kcal (Men = 1,846 kcal, Women = 1,509 kcal), 179 kcal (11.3%) was added at the step 3. In the step 3, nutrient intakes increased significantly except retinol in total subjects and except retinol and cholesterol in males but all nutrients increased significantly in females. The final probing step can add significant information on intakes of foods and many nutrients with only about 38 seconds of interview time. Confirmation of the results with larger samples of different age groups is needed.

Objective To evaluate the influence of diet structure and physical activity on the lipid level in different area of China.Methods A total of 145 people were selected by simple random sampling,including 52 residents,45 urban residents of Panzhihua and 48 rural residents of Panzhihua,each of them undergoing the laboratory examination and dietary and physical activity survey.Food frequency questionnaire and physical activity questionnaire were used.Results The blood sugar,TC and LDL-C level in Shanghai residents were higher than those of urban and rural residents of Panzhihua(P0.05)while the energy exhaust of Shanghai residents was higher than those of urban and rural residents of Panzhihua(P
ABSTRACT
The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

To study diffrences in dietary factors among communities with different living environments, we carried out a survey by the Cardiac Study method in 241 people (106 men and 135 women) aged between 50 and 54 years who were selected by random sampling from a total of 37, 000 inhabitants in a small city. The city was geographically divided into town, flatland farming area, and mountainous farming area, and the results of the survey were compared among these areas.<BR>The mean Na excretion in 24-hour specimens of urine was slightly higher in the mountainous farming area than in the other two-areas. The mean serum total cholesterol was higher in men in the town than in those in the other areas.<BR>Factor analysis of the data for nutrient intake patterns revealed a lower fat intake in the two farming areas than in the town in the men, and a higher intake of animal foods in the town and a lower fat intake in the mountainous area in the women.<BR>These results show that risk factors for circulatory diseases such as urinary Na excretion, serum cholesterol level, and nutrient intake patterns differ even among small areas if the living environment differs.
