Dietary Intake of Adolescents and Alignment with Recommendations for Healthy and Sustainable Diets: Results of the SI.Menu Study.

BACKGROUND: The SI.Menu study offers the latest data on the dietary intake of Slovenian adolescents aged 10 to 17. The purpose of this study is to comprehensively assess their dietary intake (energy and nutrients) and compare their food intakes with dietary recommendations for healthy and sustainable diets. METHODS: The cross-sectional epidemiological dietary study SI.Menu (March 2017-April 2018) was conducted on a representative sample of Slovenian adolescents aged 10 to 17 years (n = 468) (230 males and 238 females). Data on dietary intake were gathered through two non-consecutive 24 h recalls, in line with the European Food Safety Authority (EFSA) EU Menu methodology. The repeated 24 h Dietary Recall (HDR) and Food Propensity Questionnaire (FPQ) data were combined to determine the usual intakes of nutrients and food groups, using the Multiple Source Method (MSM) program. RESULTS: Adolescents' diets significantly deviate from dietary recommendations, lacking vegetables, milk and dairy products, nuts and seeds, legumes, and water, while containing excessive meat (especially red meat) and high-sugar foods. This results in insufficient intake of dietary fibre, and nutrients such as vitamin D, folate, and calcium. CONCLUSIONS: The dietary intake of Slovenian adolescents does not meet healthy and sustainable diet recommendations. This study provides an important insight into the dietary habits of Slovenian adolescents that could be useful for future public health strategies.

Design, Methods, and Participation in Riksmaten Young Children-A Swedish National Dietary Survey.

Background: National dietary surveys provide essential data for risk benefit assessments of foods and nutrients, for management and policy development. Physical activity measurement and biomonitoring can provide important complementary data but are less commonly included. Objectives: This study aimed to describe the study design and methods of the cross-sectional Swedish national dietary survey Riksmaten Young Children (Riksmaten småbarn), of children aged 9 mo, 18 mo, and 4 y. Participation/dropout rates for the 2 older age groups are also presented. The impact of different recruitment strategies is discussed. Methods: Children (N = 16,655) were randomly selected from the population register; invitations to guardians were sent by post and where possible, followed up by telephone. Food intake was assessed by a 2-d food diary and/or questionnaire. Height and weight were reported after measurement. Physical activity (accelerometery, 7 d) and stool, blood, and urine samples were assessed in subgroups. Results: Food consumption data were collected in 1828 children (11% of the invited; 18 mo: n = 1078, and 4 y: n = 750). Of participants also in subgroups, 71% provided physical activity data (n = 1307), 60% stool samples (n = 630), and 51% blood and/or urine samples (n = 593). The study population represented all geographic regions and types of municipalities in Sweden, but participating households had both higher education level and higher income than the target population. Only minor differences were seen in participation rates between recruitment via post and telephone compared with those through post only (12% compared with 10%). Repeated contact attempts were needed for the majority of participants (65%). Despite the low-participation rate, 99% of the participants completed the study once started. Conclusions: Although it was a challenge to recruit participants, Riksmaten Young Children provides a substantial amount of information at national level, representative in terms of sex, geography, and family structure. The underrepresentation of households with lower socioeconomic position must be considered when generalizing results.

Intake of Table Sugar and Their Corresponding Food Sources in Adults from the 2017-2018 Brazilian National Dietary Survey.

Excessive intake of free sugars is associated with adverse health outcomes. Table sugar is one of the main dietary sources of free sugars; however, the amount added by Brazilian consumers in their culinary preparations is unknown. The aims were to estimate the daily intake of table sugar (g/day), its contribution to total energy intake (E%) and the main food groups that contribute to the intake of this sugar in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey). Based on two 24-h recalls adjusted for the within-person variation, the overall median table sugar intake was 14.3 g/day, corresponding to 3.2 E%. Males, individuals living in rural areas, with low income, low education and experiencing food insecurity had a higher intake of table sugar. The main food sources of table sugar were coffee (55.8%), juice (33.9%), milk-based preparations and smoothies (3.1%), powdered and processed juice (2.7%), whole milk (1.9%), and tea (1.6%). There are no recommendations regarding the limit of table sugar intake, but considering that the WHO limits the intake of free sugars to <10 E%, it is concluded that table sugar intake by Brazilians corresponds to about 30% of the upper recommended daily intake of free sugars.

Dietary survey of poultry egg intake among residents in Kunming city, southwest China.

Background: For almost all people, eggs can be a wholesome addition to the diet. However, there is insufficient applicable data to evaluate the poultry egg intake of people in the city of Kunming located in southwest China. Objectives: To understand the situation of egg consumption among local residents in Kunming via a dietary survey. Methods: Residents living in three places of Kunming were chosen using a multi-stage random sampling method. The recall methods of 3-day food intake and 1-month food intake frequency were used to assess the quantity and frequency of poultry egg dietary intake of local people. Results: Of the 1,118 respondents, 565 (50.54%) were female and 553 (49.46%) were male with age range 0.5-91 years old. Egg consumption was widespread among the survey respondents with 88.01% reporting hen egg ingestion, but the dietary intake of other poultry eggs such as duck, quail, and goose eggs were much less frequent. The medium daily intake of hen eggs was 20.00 g/d with greater amount of hen egg consumption in older age groups. However, when calculated on a body-weight basis, the median amount of hen eggs consumed daily per kilogram of body weight for all survey respondents was 0.47 g/kg/d whereas this indicator for children was 1.33 g/kg/d, becoming the greatest among all age groups. Conclusions: Our study obtained a better understanding of poultry egg intake among residents in Kunming city and calculated the egg intake kilogram of body weight that can be a useful reference to inform the development of more accurate dietary recommendation. These results also provide basic data for nutrition monitoring and dietary exposure risk assessment of poultry egg intake.

Association between ultra-processed food and snacking behavior in Brazil.

PURPOSE: Ultra-processed food may play a role in facilitating snacking behavior because of their convenience and low satiety potential. This study aimed to describe the association between consumption of ultra-processed foods and frequency of snacking. METHODS: We analyzed data from 46,164 participants (≥ 10 years old) in the 2017-2018 Brazilian Household Budget Survey. Dietary data were collected by 24-h dietary recalls over one or two days for each participant. We estimated energy intake, ultra-processed food consumption, and level of snacking. We measured the association between ultra-processed food consumption and level of snacking using multinomial logistic regression, stratified by age group (adolescents, 10-19 years old; adults, 20-64 years old; elders, 65 or older). RESULTS: We found a statistically significant tendency of increased daily energy intake and consumption of snacks and that ultra-processed food consumption was positively associated with the level of snacking for all age groups. For adolescents, adults, and elders in the highest quintile of ultra-processed food consumption as a share of their entire diet, the relative risk ratio (95% CI) of having more than two snacks per day compared to no snacks was 14.21 (9.09-22.21), 4.44 (3.54-5.57), and 4.21 (2.67-6.64), respectively, when compared to the lowest quintile. CONCLUSION: Higher consumption of ultra-processed food was associated with snacking behavior, and the strength of this association was stronger among adolescents. Efforts to mitigate ultra-processed food attributes that facilitate snacking should be incorporated into strategies to promote healthier food choices, especially among adolescents.

Dietary Intake of Soccer Players before, during and after an Official Game: Influence of Competition Level and Playing Position.

Physical demands in soccer differ according to league level and playing position and may influence nutritional requirements. This study examined the effect of competition level and playing position on dietary intake in male soccer players (SP). Diet was weighed and recorded by 123 SP for 3 days; before, on the day, and the day after an official match. SP in the Super League (SL, n = 33) division reported higher (p < 0.05) average three-day energy (195 ± 36 kJ/kg), carbohydrate (6.0 ± 1.1 g/kg), and protein (2.2 ± 0.5 g/kg) intakes compared to the intakes reported by SP in the 2nd (n = 30) (energy: 159 ± 31 kJ/kg; carbohydrate: 4.6 ± 1.2 g/kg; protein: 1.9 ± 0.4 g/kg), 3rd (n = 30) (energy: 153 ± 34 kJ/kg; carbohydrate: 4.5 ± 1.2 g/kg; protein: 1.7 ± 0.4 g/kg), and 4th (n = 30) (energy: 152 ± 36 kJ/kg; carbohydrate: 4.2 ± 1.2 g/kg; protein: 1.7 ± 0.5 g/kg) national leagues (mean ± SD). Furthermore, when data were analyzed by playing position (pooled data), wide midfielders reported higher (p < 0.05) energy (183 ± 33 kJ/kg), carbohydrate (5.4 ± 1.2 g/kg), and fat (1.5 ± 0.4 g/kg) intakes compared to central defenders (energy: 147 ± 37 kJ/kg; carbohydrate: 4.1 ± 1.1 g/kg; fat: 1.2 ± 0.4 g/kg). The dietary intake of SP may differ according to the playing position and competition level, possibly due to different metabolic demands in training and competition.

Time Trends in Income-related Differences in Food Group Intakes: The National Health and Nutrition Survey, Japan in 2010, 2014, and 2018.

BACKGROUND: We aimed to clarify whether differences in food group intake according to household income have changed over the last decade in Japanese people aged 20 years or older. METHODS: This cross-sectional study was based on the 2010, 2014, and 2018 National Health and Nutrition Surveys in Japan. Food intake was assessed using a 1-day semi-weighed household dietary record. The participants were categorized into three groups based on their income. The mean of each food intake according to the income group was estimated by adjusting for age, occupation, and number of participants from the same household. The significance of the interaction terms between income and survey year was evaluated to assess the change in income-related differences in food intake over time. RESULTS: Cereal intake was lower in the middle- and the highest-income groups than in the lowest-income group, regardless of sex, and the interaction between income and year was nonsignificant for cereal intake. In the former two surveys, vegetable intake was higher among the highest-income women, while in the 2018 survey, the vegetable intake decreased in the women in the middle- and the highest-income groups. The interaction between income and year was significant for vegetable intake among the women. For other foods, the differences in intake among the income groups did not significantly change over time. CONCLUSION: The tendency for lower cereal intake in the higher-income groups was consistent over time in both the sexes, and the tendency for higher vegetable intake in the highest income women disappeared over time.

[Analysis of diet structure of Kashin-beck disease area in Chamdo-Lhorong of Tibet in 2021].

OBJECTIVE: To investigate and compare the dietary structure between healthy people and patients in KBD area of Chamdo-Lhorong of Tibet. METHODS: A case-control study design was used, retrospectively select patients who had completed screening and registered in the national Kashin-Beck Disease surveillance system in 2021 in Luolong County, Qamdo, Tibet as the source population of the case group, and randomly selected people who had not been screened for Kashin-Beck disease in the same county as the control group. The self-made diet questionnaire was used to record the types of food consumption, frequency of food intake, basic information of the respondents, family size and other basic information in the past year by one-on-one interview. RESULTS: The staple food with the highest response among the patients(97.33%) was rice(rice/rice noodle), and the highest response among the healthy people(90%) was non-wheat products, non-fried pasta(bread/steamed bun/noodles/dumplings), except instant noodles.78.7% of patients chose not to eat local wheat(Tibetan noodles), and the number of non-patients who chose to eat non-local wheat(Tibetan noodles) 3-4 times a week was significantly higher than that of patients. The meat and meat products with the highest response in both patients(93.33%) and healthy people(90%) was yak meat(local). The control group also chose to consume beef(non-local/lamb/mutton/other non-processed meat), poultry and livestock offal, fish(all seawater and freshwater fish), shrimp and crabs or other seafood, and their consumption rate and intake frequency were significantly higher than those of the case group. The consumption rate and frequency of tomato, onion and garlic(garlic shoots/leek/onion/onion) and fresh eggs(egg/duck egg/quail egg/goose egg) in control group were significantly higher than those in case group. There was no significant difference in consumption rate and frequency of fruits, milk and dairy products between the two groups. CONCLUSION: In addition to the local highland barley(zanba), most people also chose to purchase rice and flour, which changed the situation of single staple food in the past. However, compared with the healthy population in the disease area, the consumption rate and intake frequency of fish, shrimp and crabs, poultry and livestock viscera, eggs(fresh eggs) and vegetables(tomatoes, scallions, ginger and garlic) in KBD patients were significantly lower, the selection of meat varieties is single, mainly local yak meat, and the overall dietary structure still presents the risk of single type and unbalanced diet.

Study of the dietary and anthropometric profile and identification of determining factors in adolescents at school in the Khemisset region of Morocco.

Background: The nutritional status and dietary diversity of adolescents play a crucial role in their growth, development, and overall health. Objective: The aim of this study is to assess the nutritional status and determine the dietary diversity score in urban and rural school settings among Moroccan adolescents. Material and Methods: We conducted a descriptive cross-sectional study in public schools in Khemisset in the municipality of Sidi Allal El Bahraoui, Morocco. We used a questionnaire to collect sociodemographic data and a 24- hour dietary recall to calculate the dietary diversity score. Results: This study included 215 students. The mean BMI was 21.06 ± 0.23 kg/m2, with 60.8% of students having a normal BMI, 24.5% being underweight, 11.8% overweight, and 2.8% obese. The mean dietary diversity score was 5.672±0.956, with 21% having a low dietary diversity score, 12% having a high score, and 67% having a moderate score. Factors associated with nutritional status were place of residence, type of delivery, and age, while the dietary diversity score was associated with school level and BMI of adolescents. Conclusion: The data from the study show that the diet of adolescents in the Khemisset region of Morocco is moderately diversified. In addition, the prevalence of underweight and overweight was worrying, underlining the need for multiple strategic interventions to improve the health status of adolescents.

Consumption of Bivalve Shellfish in French Coastal Populations: Data for Acute and Chronic Exposure Assessment.

Shellfish are a source of nutrients but are also a matter of concern in terms of food safety due to natural contaminants such as phycotoxins or anthropogenic contaminants including microbial agents and heavy metals. However, data related to consumption for each mollusk species are scarce and missing for appropriate exposure calculation. The objective of the study was to generate shellfish consumption data in the adult coastal population in France to assess exposure to health risks, the effects of determinants on the frequency of consumption and usual intake, and shellfish food risk perception. Our study, named the CONSOMER study, was carried out using an online survey in 2016 and 2017 and included a food frequency questionnaire. After validation, 2,479 individual questionnaires were available for statistical analysis. Our findings provide estimates of shellfish consumption frequency, portion sizes, weekly intake in g/week, and g/week/body weight that can be used for acute and chronic exposure calculations. For the acute risk, the 97.5th percentile of the portion size was found to be around 290 g for the adult coastal population. For chronic exposure, recreational shellfish harvesting activities were associated with higher weekly intakes. A non-negligible part of this subpopulation is not aware of food safety recommendations concerning harvesting areas. Results for shellfish harvester consumption in particular are consistent with other available data. Exposure calculations and safety recommendations should target shellfish harvesters.

Higher Intake of Nutrients with Antioxidant and Anti-Inflammatory Effects among Children with Cow's Milk Allergy According to the Degree of Elimination.

Children with cow's milk allergy (CMA) have lower bone mineral density and shorter height than children without CMA or non-food allergy (FA), and their final height is also affected. Appropriate nutritional guidance for CMA children is therefore needed. The purpose of this study was to conduct a dietary survey of CMA children and to compare their characteristics according to the degree of elimination. A dietary survey of FA children attending the allergy clinic at Shiga Medical Center for Children, Shiga, Japan, was conducted using the brief-type self-administered diet history questionnaire for Japanese children and adolescents (BDHQ15y). To objectively assess the intake of fruit and vegetables, skin carotenoid levels were measured using the Veggie Meter®. Regarding the degree of CM elimination, of the 147 FA children (89 boys, 58 girls) recruited, 38, 27, and 82 children were allocated to complete-, partial-, and non-elimination groups, respectively. In analyzing the data, boys and girls were combined because there was no difference in sex ratio among the groups. Significantly lower intakes of calcium, animal proteins, and vitamin B2 were observed with increasing degree of CM elimination. Conversely, significantly greater intakes of vegetable proteins, ß carotene, α tocopherol, vitamin C, and polyunsaturated fatty acids, as well as significantly higher levels of skin carotenoids, were observed with increasing degree of CM elimination. Intakes of many nutrients with antioxidant and anti-inflammatory effects were higher with increasing degree of CM elimination, presumably reflecting the efforts of caregivers in identifying alternative foods. However, calcium intake was still inadequate, indicating a need for further encouragement of calcium intake in CMA children.

Knowledge, attitude, and patient advice on sustainable diets among Spanish health professionals.

Current dietary patterns, especially in high-income countries, are unsustainable. Health professionals, due to their credibility and close contact with the general population, could serve as agents of change for the adoption of sustainable diets. The objective of this study was to assess the knowledge and attitude regarding sustainable diets among the health professionals in Spain. A 24-item online questionnaire was designed for this purpose, and sent to health professionals (i.e., dietitians-nutritionists, nurses, physicians, and pharmacists). From September 2021 to May 2022, 2,545 health professionals answered the survey completely. One-fifth of them had never heard the term "sustainable diet", and most of them recognized having limited knowledge about it. They considered promoting sustainable diets when making dietary recommendations important, and pointed out that they would like to be trained on the topic. Indeed, they reported that all health professionals, independent of their career background, should be educated on sustainable diets. Efforts should be stressed on implementing training courses, at university level but also as continuous post-graduate training, providing health professionals in Spain the necessary knowledge to promote the adoption of sustainable diets among the population.

Dietary Intake of Polyunsaturated Fatty Acids and Diabetic Nephropathy: Cohort Analysis of the Tsugaru Study.

BACKGROUND/AIM: Diabetic nephropathy (DN) is the leading cause of end-stage renal failure and its incidence continues to increase. To decrease this, a countermeasure from an early stage is required. This is a DN stage 2 observation study that analyzed the results of a concurrent dietary survey in the Tsugaru study and discussed the relationship between dietary intake of n-3 fatty acid and DN. PATIENTS AND METHODS: Patients with stage 2 DN and aged 20 years or older in the Tsugaru region of Aomori Prefecture were enrolled. We examined the association between urinary albumin excretion (UAE) at enrollment and 36 months later and n-3PUFA intake obtained from a dietary survey. RESULTS: Of the 317 subjects at enrollment, 234 were followed for 36 months, of whom 123 were able to complete the dietary survey. After 36 months of follow-up of these 123 subjects, 28 were in remission and 18 had progressed. Correlations between UAE at 36 months and each of the parameters were examined and UAE at enrollment showed a positive correlation (r=0.4224, p<0.001); correlations between eicosapentaenoic acid (EPA)/arachidonic acid (AA), EPA+docosahexaenoic acid/AA, and n-6/n-3 and UAE at 36 months were weak. As shown by multiple regression analysis, the factor influencing UAE after 36 months was UAE at enrollment. CONCLUSION: Concerning the relationship between fatty acid intake balance and UAE, the previously reported renoprotective effect of n-3 fatty acids could not be demonstrated.

Quantitative analysis of the minimum days of dietary survey to estimate dietary pesticide exposure: Implications for dietary pesticide sampling strategy.

Populations are exposed to pesticides through diet on a daily basis. However, there is no research guiding how to evaluate dietary pesticide exposure, and researchers used 1-day, 3-days, 7-days or even longer dietary survey to evaluate without any consensus. It is important for dietary pesticide evaluation to identify the minimum survey days. To increase knowledge of this, a data combination was applied between a two-wave consecutive repeated-measures study in Baoding City and the Fifth China Total Diet Study. Further policy consistency on pesticides were evaluated to explain its credibility. We computed the sensitivity and specificity to evaluate how well different days of dietary survey classify participants with high exposure, and calculated the minimum days required to estimate the participant-specific mean at different acceptable error range. With 1 day of dietary survey, the classification sensitivity was low (<0.6) for total HCH, endosulfan, chlordane, cyhalothrin, allethrin, and prallethrin; that for the other pesticides was high sensitivity (≥0.6). Sensitivity increased as the number of days increased, and the maximum marginal sensitivity increase (≥0.039) occurred from 1 to 2 days for all pesticides except phenothrin, whose maximum marginal sensitivity increase (0.042) occurred from 2 to 3 days. The specificity increased gradually from 0.8 to 0.9 from 1 to 7 days. Under the acceptable error range of 0.5%, 3-28 days were required for participant-specific mean estimation and 1-7 days were required when acceptable error range was shrunk in 1%. Only 1 day was enough if 5% error range was acceptable. In conclusion, 3 days in the study period was cost-effective to distinguish high exposure group, and it rose to 7 when estimating participant-specific mean from a conservative perspective. This study can serve as a reference to determine the minimum survey days for epidemiological studies employing dietary surveys.

[Nutrient intake and nutritional status of 4-10-year-old Hungarian children]. / 4­10 éves magyar gyermekek tápanyagbeviteli és tápláltsági állapotának felmérése.

INTRODUCTION AND OBJECTIVE: The growing trend of childhood obesity is a major public health issue. Collaborations between medical and healthcare professionals, preventive and health preservative programs, dietary habit and nutrient intake studies are indispensable. METHOD: A representative study has been performed among 4-10-year-old Hungarian children by gender, age, size of settlement and region. The study included 733 assessable questionnaires and 666 dietary records. Data on children's eating habits were collected by using the internationally recommended three-day dietary record method. Body weight and height measurements were taken for each child to determine nutritional status. Data were analyzed with statistical methods. RESULTS: The rate of overweight and obesity is 23%. Energy intake differs significantly between body mass index groups. The children's fat intake is excessive (34.2 energy%), the saturated fatty acid intake exceeds the recommended 10 energy%, omega fatty acid ratio is disadvantageous and the children's cholesterol intake is high. The average energy from carbohydrates is below the recommended 57 energy%, from added sugar it is 11%, which affects 52% of the children. Their low fibre intake (19.4 g/day) is due to low fruit, vegetable (263 g/day) and whole grain consumption. Of the micronutrients, sodium intake is 3-4 times higher than the recommended. In 35% of the children, the calcium intake is below the critical threshold, due to unfavourable milk and milk product consumption (290 g/day). Vitamin D intake was low in 98-100% of the children. CONCLUSION: Compared to the results of other European and national studies performed among children, adolescent and adults, the nutritional status and nutrient intake of our sample is unfavourable. Comprehensive intervention, education of the children with the involvement of their parents is essential to reduce obesity. Orv Hetil. 2023; 164(14): 533-540.

Assessment of the Iodine Status of Lactating Women and Infants in Shanghai, China.

There is a risk of iodine deficiency among pregnant women in China. However, research on the iodine status of lactating women and infants is scarce. In this study, we aimed to evaluate the iodine status of lactating women and their infants and explore the relationship between breast milk iodine concentrations (BMICs) and urinary iodine concentrations (UICs). In total, 257 lactating women and their infants were recruited from the Shanghai Sixth People's Hospital East campus between May 2018 and May 2019. The BMIC and UIC were measured by inductively coupled plasma‒mass spectrometry (ICP‒MS). One-day 24-h dietary recall was used to determine the dietary intake of iodine. The mean dietary intake of iodine among the lactating women was 145.1 µg/day, and 97.83% (n = 225) of the lactating women had a dietary iodine intake below 240 µg/day. The median BMIC and UIC of the lactating women was 150.7 µg/L (interquartile range, IQR 102.9, 205.5) and 110.0 µg/L (IQR 65.8, 171.4), respectively, and the median UIC of the infants was 212.7 µg/L (IQR 142.1, 320.6). The BMIC of lactating women who consumed iodized salt was significantly higher than that of lactating women who did not consume iodized salt (p = 0.015). The infants' UIC values were significantly correlated with the BMIC values (r = 0.597**, p < 0.001). The iodine nutritional status of lactating women and infants in Shanghai was generally sufficient according to the WHO's iodine nutritional status recommendation. The use of iodized salt was related to increasing dietary iodine intake and the BMIC. Improvements in BMICs have positive effects on the nutritional levels of iodine in infants.

[Evaluation of calcium intake levels and sources among pregnant women in a Chengdu hospital in 2017].

OBJECTIVE: Investigate and evaluate the levels and sources of calcium intake of pregnant women in Chengdu during three trimesters. METHODS: Use the data of a cohort study in Chengdu in 2017. The healthy singleton pregnant women with 8-14 weeks of pregnancy in an obstetrical clinic of a maternal-and-child health care institution in Chengdu were selected as the object of the study. Data on maternal demographic characteristics and the use information of calcium supplements in the past month of each trimester were collected by questionnaire investigation. The dietary intakes data of pregnant women in each trimester was collected by the 3-day 24-hour dietary recall method. The dietary calcium intake and the contribution of calcium from different foods were calculated based on the Chinese Food Composition Table(2018). The total calcium intake was obtained by adding the dietary calcium and supplement calcium intake. The calcium intake was evaluated with reference to the Chinese Dietary Nutrient Reference Intakes(2013). RESULTS: Valid samples of 1653 cases in early pregnancy, 1024 cases in middle pregnancy and 1017 cases in late pregnancy were finally included. The median intake of total calcium was 523.3, 1280.5 and 1491.3 mg/d in three trimesters, respectively. The adequate rate of total calcium intake was 16.3%, 63.2% and 67.1%, the insufficient rate was 69.0%, 15.7% and 11.2%, the excess rate was 0.2%, 9.1% and 14.4%, respectively. The median intake of dietary calcium was 453.0, 613.0 and 723.0 mg/d in three trimesters respectively. The dietary calcium adequate rates were 7.1%, 9.7% and 16.2%, the dietary calcium deficiency rates were 82.0%, 75.0%, 62.6%, respectively. The main food sources of dietary calcium in each pregnancy were dairy foods, vegetables, tubers and grains. The contribution of dairy foods to the dietary calcium was 33.8%, 37.7% and 40.2%, respectively. The median intake of milk was 125.0, 235.3 and 250.0 g/d, respectively. Among all pregnant women, the calcium supplement use in three trimesters was 36.2%, 93.4% and 91.7%, respectively; the median intake of supplement calcium was 0.0, 625.0 and 750.0 mg/d, respectively. Among pregnant women who met the dietary calcium standard, the use of calcium supplements in the three trimesters was 38.1%, 95.0% and 94.5%, respectively; the median intake of supplemental calcium was 0.0, 725.0 and 750.0 mg/d, respectively. CONCLUSION: The insufficient and excessive total calcium intake coexisted among pregnant women in Chengdu, with the insufficient dietary calcium intake prominent in all trimesters. The use of calcium supplements was common in middle and late pregnancy.

Validation of a Brief Dietary Questionnaire for Use in Clinical Practice: Mini-EAT (Eating Assessment Tool).

Background There is a scarcity of validated rapid dietary screening tools for patient use in the clinical setting to improve health and reduce cardiovascular risk. The Healthy Eating Index (HEI) 2015 measures compliance with the 2015 to 2020 Dietary Guidelines for Americans but requires completion of an extensive diet assessment to compute, which is time consuming and impractical. The authors hypothesize that a 19-item dietary survey assessing consumption of common food groups known to affect health will be correlated with the HEI-2015 assessed by a validated food frequency questionnaire and can be further reduced without affecting validity. Methods and Results A 19-item Eating Assessment Tool (EAT) of common food groups was created through literature review and expert consensus. A cross-sectional survey was then conducted in adult participants from a preventive cardiology clinic or cardiac rehabilitation and in healthy volunteers (n=661, mean age, 36 years; 76% women). Participants completed an online 156-item food frequency questionnaire, which was used to calculate the HEI score using standard methods. The association between each EAT question and HEI group was analyzed by Kruskal-Wallis test. Linear regression models were subsequently used to identify univariable and multivariable predictors for HEI score for further reduction in the number of items. The final 9-item model of Mini-EAT was validated by 5-fold cross validation. The 19-item EAT had a strong correlation with the HEI score (r=0.73) and was subsequently reduced to the 9 items independently predictive of the HEI score: fruits, vegetables, whole grains, refined grains, fish or seafood, legumes/nuts/seeds, low-fat dairy, high-fat dairy, and sweets consumption, without affecting the predictive ability of the tool (r=0.71). Conclusions Mini-EAT is a 9-item validated brief dietary screener that correlates well with a comprehensive food frequency questionnaire. Future studies to test the Mini-EAT's validity in diverse populations and for development of clinical decision support systems to capture changes over time are needed.

Criterion Validity of a Short Food Frequency Questionnaire for Mexican American Adults.

Background: The purpose of this study was to validate the School Physical Activity and Nutrition (SPAN) Food Frequency Questionnaire (FFQ) for Mexican American adults (SPAN MAA). Methods: A sample of 100 Mexican American adult participants was drawn from the Cameron County Hispanic Cohort (on the Texas−Mexico border). We used Spearman rank order correlation coefficients, kappa statistics, and percent agreement to compare the SPAN MAA questionnaire to a 24 h recall collected on the same day. Results: Of 100 participants, 93 were included in the analyses. One item showed substantial (>0.6), five items moderate (>0.4), five items fair (>0.2) and three items little to no agreement (<0.2). Items with low agreement were those reported in low frequencies by study participants. Conclusions: SPAN MAA FFQ had moderate to fair agreement between instruments across both sexes, making this brief questionnaire a useful tool to quickly assess the dietary intake patterns of Mexican American adults.

Dietary sodium intake remains high in Brazil: Data from the Brazilian National Dietary Surveys, 2008-2009 and 2017-2018.

Reducing salt intake is considered one of the most cost-effective interventions to decrease morbidity and mortality resulting from noncommunicable diseases. This study aimed to describe changes in sodium intake in the Brazilian population using data from the National Dietary Surveys (NDS) conducted in 2008-2009 and 2017-2018. We hypothesized that over the 10-year period evaluated, sodium intake has remained high in Brazil. Nationwide representative samples of 34,003 and 46,164 individuals (aged ≥10 years) from NDS 2008-2009 and 2017-2018, respectively, were evaluated. Food consumption data were obtained from 2 nonconsecutive food records (NDS 2008-2009) and two 24-hour food recalls (NDS 2017-2018). Trends, percentiles of distribution, and proportions of the population exceeding the age-specific tolerable upper intake level for sodium were estimated. Dietary sodium intake was also estimated as a function of energy intake (mg/1000 kcal). Overall, mean crude daily sodium intake was slightly lower in 2017-2018 than in 2008-2009 (2489 mg/d vs. 2529 mg/d). The decrease in sodium intake (mg/day) was statistically significant (P < .05) only among female adolescents and subjects in the highest income level. Additionally, an overall statistically significant increase in dietary sodium density was observed independent of age, sex, and income level for energy-adjusted data (P < .05). Our findings indicate that sodium intake has not significantly changed over time in the Brazilian population; thus, policies aimed at reducing sodium intake in Brazil are necessary.
