Is Dietary (Food) Supplement Intake Reported in European National Nutrition Surveys?

Dietary (food) supplements (DSs) have seen a sharp increase in use and popularity in recent years. Information on DS consumption is vital for national nutrition monitoring. The objective of this study was to investigate whether DS intake was reported in the National Nutrition Surveys (NNSs) in all European countries. NNSs reporting DS use were retrieved via literature review (i.e., PubMed, Google Scholar, Scopus), scientific and organizational publications (EFSA), or open-published government and other official reports. Included were the European NNSs referring to adults, published in English, French, or German, post-2000. Out of the 53 European countries, 30 recorded DS intake. Among them, related findings on the percentage of DS intake were published in 21 cases, 5 of them written in the local language. DS use varied by nation, with Finland and Denmark having the greatest (over 50%) and Italy having the lowest percentage (5%). In terms of comprehensive reported data on DS consumption in Europe and the investigation of the contribution of DSs to total nutrient intake, there is a need for improvement. Common DS categories should be defined upon agreement among the involved scientific parties to allow for comparable data and estimations between surveys.

National Diet and Nutrition Survey data reveal a decline in folate status in the United Kingdom population between 2008 and 2019.

BACKGROUND: Folate is essential for healthy growth and development. Fortification of foods with folic acid can improve folate status and reduce risk of neural tube defects (NTD). Following concern around folate status in the United Kingdom, the United Kingdom government announced in 2021 the intention to introduce mandatory folic acid fortification. OBJECTIVE: This study aimed to describe folate status in the United Kingdom population prior to the implementation of mandatory folic acid fortification of non-whole wheat (non-wholemeal) flour and to assess trends in folate status, including in females of reproductive age (FRA). METHODS: Data were from the United Kingdom National Diet and Nutrition Survey Rolling Program (2008-2019), a cross-sectional, nationally representative survey of children and adults aged 1.5+ (n = 5792 with folate result). Serum folate concentration was measured by liquid chromatography tandem mass spectrometry (LC-MS/MS) and red blood cell (RBC) folate concentration by microbiological assay. Concentration data were compared against method-specific cut-offs and thresholds, and relationships were explored against demographic and lifestyle characteristics. RESULTS: RBC and serum folate concentration significantly decreased by ∼3 percentage points per year between 2008 and 2019 in all age/sex groups. Prevalence of deficiency (RBC folate < 305 nmol/L) was highest in children aged 11 to 18 y (17% in 2016-2019). The proportion of FRA below the cut-off for increased risk of NTD (RBC folate < 748 nmol/L) increased from 69% to 89% between 2008 and 2019. Ethnicity, smoking status, and income were significant determinants of RBC and serum folate concentrations. CONCLUSIONS: These data reveal a decline in population folate status in the United Kingdom between 2008 and 2019 and a high prevalence of folate deficiency. A high proportion of FRA had RBC folate concentrations below the cut-off for increased risk of NTD. These data provide information on folate status in a population not currently exposed to mandatory folic acid fortification and are essential to model and assess its impact.

Diabetes Mellitus in the Elderly Adults in Korea: Based on Data from the Korea National Health and Nutrition Examination Survey 2019 to 2020.

BACKGRUOUND: We evaluated the prevalence and management of diabetes mellitus (DM) in elderly Korean patients based on data from the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A total of 3,068 adults aged 65 years and older (19.8% of total population) were analyzed using KNHANES from 2019 to 2020. Prevalence, awareness, treatment, and control rates, and comorbidities were analyzed. Lifestyle behaviors and energy intake were also measured. RESULTS: The prevalence of DM and prediabetes was 29.6% and 50.5%, respectively. The awareness, treatment and control rates were 76.4%, 73.3%, and 28.3%, respectively. The control rate was 77.0% if A1C <7.5% criteria was used. The mean A1C value of individuals with known DM was 7.1%, and 14.5% of the known DM patients had A1C ≥8.0%. Abdominal obesity, hypertension, and hypercholesterolemia were combined with DM in 63.9%, 71.7%, and 70.7%, respectively, and the rate of integrated management was 36.0% (A1C <7.5% criteria). A total of 40.1% of those with DM walked regularly. The percentage of energy intake from carbohydrates was higher in those with DM than in those without DM (P=0.044), while those of fat (P=0.003) and protein (P=0.025) were lower in those with DM than in those without DM in women. CONCLUSION: In 2019 to 2020, three of 10 adults aged 65 years and older in Korea had DM, and approximately 70% of them had comorbidities. A strategy for more individualized comprehensive care for the elderly patients with DM is urgently needed.

Relationship between Serum Selenium Level and Self-Reported History of Kidney Stone.

A relationship may exist between selenium and kidney calculi, but there is a lack of research in this field at present. Our study explored the relationship between the serum selenium level and a medical history of adult kidney calculi. We utilized data from the National Health and Nutrition Examination Survey conducted between 2011 and 2016. Participants self-reported their history of kidney stones, while serum selenium levels were measured using inductively coupled plasma dynamic reaction cell mass spectrometry. Our findings indicate a negative correlation between serum selenium levels and the risk of kidney stone history. In the multiple-adjusted model, the lowest serum selenium level group had a higher risk than the other groups. The odds ratio (95% confidence interval) of ever having kidney stones for the highest serum selenium level group was 0.54 (0.33-0.88). In the results of stratified analysis, this relationship was still significant in the groups of women and those 40-59 years. We also found that as a nonlinear dose-response relationship between serum selenium levels and the history of kidney stones disease. In our research, we found that people with higher serum selenium levels had a lower risk of having a history of kidney stones. We concluded that selenium may have a protective effect on kidney stones. In the future, more population studies are needed to explore the relationship between selenium and kidney stones.

Selenium intakes in the Irish adult population.

Selenium (Se) is an essential trace element which has an important role as a constituent of seleno-proteins involved in various physiological processes. Previous research in Irish adults suggests that intakes of this important nutrient are suboptimal. The aim of the present study was to estimate the current intakes and major food sources of Se by Irish adults. Mean daily intakes (MDIs) of Se were calculated using data from the National Adult Nutrition Survey which involved 1500 Irish adults aged 18-90 years. The Se content of foods and drinks consumed over a 4-d period was determined using data from the Irish Total Diet Study (TDS). Adequacy of Se intakes was assessed by calculating the proportion of the population with intakes below the adequate intake (AI) of 70 µg/d and lower reference nutrient intake of 40 µg/d (LRNI). The MDI of Se in the total population was 71⋅7 µg/d, with significantly higher intakes reported in men (80⋅2 µg/d) compared with women (63⋅4 µg/d, P < 0⋅01). Meat and meat products were the major contributing food group to Se intakes for both men (37 %) and women (31 %). Overall, 47 % of the population were not meeting the recommended AI, while 4 % of the total population were not meeting the LRNI. Although the average intake of Se is above the AI, a significant proportion of the population is not meeting this recommendation and continued monitoring of Se intakes is necessary, particularly by at-risk groups and also in the context of sustainability.

Effect of a Single Multi-Vitamin and Mineral Supplement on Nutritional Intake in Korean Elderly: Korean National Health and Nutrition Examination Survey 2018-2020.

Inadequate nutritional intake is common, especially among elderly individuals. Although micronutrient intake may help fill nutritional gaps, the effects of multi-vitamin and mineral supplements (MVMS) among the Korean elderly are not well known. Therefore, we investigated the nutrition-improving effects of a single MVMS. A total of 2478 people aged ≥65 years who participated in the Korea National Health and Nutrition Survey 2018-2020 were analyzed. Nutrient intake from food and supplements was measured using the 24 h recall method. We compared the nutritional intake and insufficiency between the food-only group (n = 2170) and the food and MVMS group (n = 308). We also evaluated the differences in inadequate nutritional intake after taking MVMS with food. The analysis included vitamins A and C, thiamine, riboflavin, niacin, calcium, iron, and phosphorus. The proportion of insufficient intake ranged from 6.2% to 80.5% for men and from 21.2% to 82.4% for women, depending on the nutrients. Intake of MVMS with food was associated with lower rates of inadequacy (3.8-68.5% for men and 3.3-75.5% for women) compared to the food-only group. The results suggest that micronutrient deficiency frequently occurs in the Korean elderly population and can be improved by MVMS intake.

Examining dietary behaviours, diet quality, motives and supplementation use in physically active individuals following vegetarian-based eating patterns.

The adoption of vegetarian-based dietary patterns among athletes has been gaining popularity. However, limited research examines the dietary behaviours within this group. Therefore, the aim of this study was to examine self-reported dietary behaviours in a cohort of physically active individuals following vegetarian-based dietary patterns, recruited via social media. A 52-item online survey was created with questions related to demographics, physical activity, eating patterns and supplementation use. An external link to the Australian Automated Self-Administered 24-h (ASA24-AU) recall was included to examine nutrient intakes. Dietary quality was assessed using the Alternate Healthy Eating Index-2010 (AHEI-2010) and the Dietary Phytochemical Index (DPI) tools. A total of 781 (84.8%) respondents completed the survey in 2018. Principal motives for adhering to a vegetarian-based dietary pattern included animal rights (86.5%), environmental concerns (75.4%), health reasons (69.6%) and improving physical performance (24.1%). Vitamin B12 was the most commonly reported supplement (58.1%) followed by protein powder (36.3%) and vitamin D (35.9%). A total of 133 respondents completed the ASA24-AU dietary recall with generally adequate nutrient intakes and a high-quality diet as assessed by the AHEI-2010 and DPI. A significant minority of physically active individuals following vegetarian-based diets do so with the aspiration of improving their exercise performance. Dietary quality was considered high in this group for recreational physical activity, although intakes of vitamin B12 and LC n-3 PUFA were low.

Deficiency of vitamins C and E in women of childbearing age in Brazil: a systematic review and meta-analysis

ABSTRACT BACKGROUND: Despite the several options available for supplements containing vitamins C and E, evidence regarding the prevalence of deficiency or insufficiency of these vitamins is weak. OBJECTIVES: To estimate the prevalence of deficiency or insufficiency of vitamins C and E and associated factors among women of childbearing age, in Brazil. DESIGN AND SETTING: Systematic review and meta-analysis conducted at a Brazilian public university. METHODS: A search from index inception until May 2020 was conducted. Meta-analyses were performed using inverse variance for fixed models, with summary proportions calculation using Freeman-Tukey double arcsine (base case). Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. RESULTS: Our review identified 12 studies, comprising 1,316 participants, especially breastfeeding women. There was at least one quality weakness in all studies, mainly regarding sampling method (i.e. convenience sampling) and small sample size. The prevalence of vitamin C deficiency ranged from 0% to 40%. Only vitamin E deficiency was synthetized in meta-analyses, with mean prevalences of 6% regardless of the alpha-tocopherol cutoff in plasma, and 5% and 16% for cutoffs of < 1.6-12.0 mmol/l and < 16.2 mmol/l, respectively. The cumulative meta-analysis suggested that a trend to lower prevalence of vitamin E deficiency occurred in recent studies. CONCLUSIONS: Although the studies identified in this systematic review had poor methodological and reporting quality, mild-moderate vitamin C and E deficiencies were identified, especially in breastfeeding women. Thus, designing and implementing policies does not seem to be a priority, because the need has not been properly dimensioned among women of childbearing age in Brazil.

Adicción Alimentaria: ¿Otro determinante asociado a la adhesión del tratamiento nutricional? / Dependência de Alimentos: Outro determinante associado à adesão de tratamento nutricional? / Food Addiction: Another determinant associated with the adhesion of nutritional treatment

Resumen: Los Programas de Prevención Secundaria Cardiovascular se han desarrollado para mejorar el proceso de atención de pacientes con cardiopatía isquémica y/o con alto riesgo cardiovascular. Sin embargo, la adherencia terapéutica en algunos aspectos es limitada, por lo que conocer la prevalencia de adicción alimentaria en esta población podría ser de utilidad para redireccionar la intervención nutricional. El objetivo de este trabajo es estudiar la prevalencia de adicción alimentaria de los pacientes que asisten al Programa de Prevención Secundaria Cardiovascular del Fondo nacional de Recursos en el período octubre a diciembre 2016 en el departamento de Montevideo, Uruguay. Se trata de un estudio descriptivo, observacional y de corte transversal. Se estudian 153 pacientes a los que se les aplicó el cuestionario estructurado YFAS de Gearhardt y valoración del estado nutricional a través del IMC extraído del Sistema Informático María del FNR. El 63% de la población fue del sexo masculino, 8 de cada 10 de los encuestados fueron adultos mayores (≥60 años), y predominó la malnutrición por exceso en el 70% de los encuestados, encontrándose obesidad en 4 de cada 10. La prevalencia de adicción alimentaria en el total de los encuestados fue del 5,9% (IC95%=2,7-10,9), siendo más prevalente en el rango etáreo de menores de 60 años. Dentro de la categoría de obesidad la prevalencia de adicción alimentaria fue 13,8% seguida por el sobrepeso. Se observa en un 10% de la población la presencia de 3 o más síntomas para adicción alimentaria sin tener aún la significación clínica que determine la presencia de la patología, predominando esto en la población del sexo masculino y en los menores de 60 años. Esta presencia dentro de la categoría de obesidad se puede ver en un 10%. Se concluye que casi el 6% de la población presentó adicción alimentaria y que un 10% tuvieron 3 o más síntomas propios de la patología. Incluir el test en la consulta de los pacientes pertenecientes al PPSCV permitiría derivar al equipo de psicología de la institución los pacientes que así lo requieran.

Resumo: Programas secundários de prevenção cardiovascular foram desenvolvidos para melhorar o processo de atendimento de pacientes com cardiopatia isquêmica e / ou com alto risco cardiovascular. No entanto, a adesão terapêutica em alguns aspectos é limitada, portanto, conhecer a prevalência de dependência alimentar nessa população pode ser útil para redirecionar a intervenção nutricional. O objetivo deste trabalho é estudar a prevalência de dependência alimentar de pacientes do Programa de Prevenção Secundária Cardiovascular do Fundo Nacional de Recursos no período de outubro a dezembro de 2016 no departamento de Montevidéu, Uruguai. Trata-se de um estudo descritivo, observacional e transversal. Foram estudados 153 pacientes aos quais foi aplicado o questionário estruturado YFAS de Gearhardt e a avaliação do estado nutricional por meio do IMC extraído do María Informatics System do FNR. 63% da população era do sexo masculino, 8 em cada 10 entrevistados eram adultos mais velhos (≥60 anos) e a supernutrição prevaleceu em 70% dos entrevistados, com obesidade em 4 em cada 10. a prevalência de dependência alimentar no total dos entrevistados foi de 5,9% (IC95% = 2,7-10,9), sendo mais prevalente na faixa etária de crianças menores de 60 anos. Na categoria obesidade, a prevalência de dependência alimentar foi de 13,8%, seguida pelo excesso de peso. Observa-se em 10% da população a presença de 3 ou mais sintomas de dependência alimentar sem ainda ter o significado clínico que determina a presença da patologia, predominantemente na população masculina e naqueles com menos de 60 anos. Essa presença na categoria obesidade pode ser vista em 10%. Conclui-se que quase 6% da população apresentava dependência alimentar e 10% apresentavam 3 ou mais sintomas da patologia. A inclusão do teste na consulta de pacientes pertencentes ao PPSCV permitiria que os pacientes que precisassem dele se referirem à equipe de psicologia da instituição.

Summary: The Cardiovascular Secondary Prevention Programs have been developed to improve the care process for patients with ischemic heart disease and / or with high cardiovascular risk. However, the therapeutic adherence in some aspects is limited, so knowing the prevalence of food addiction in this population could be useful to redirect the nutritional intervention. The objective of this study is to study the prevalence of food addiction in patients attending the Cardiovascular Secondary Prevention Program of the National Resources Fund from October to December 2016 in the department of Montevideo. It is a descriptive, observational and cross-sectional study. 153 patients were studied, the structured YFAS questionnaire of Gearhardt was applied and the nutritional status was assessed through the IMC extracted from the Maria IT System of the FNR. 63% of the population was male, 8 out of 10 of the respondents were elderly (≥60 years), and excess malnutrition predominated in 70% of respondents, with obesity in 4 out of 10. The prevalence of food addiction in the total of the respondents was 5.9% (95% CI = 2.7-10.9), being more prevalent in the age range of those under 60 years of age. Within the category of obesity, the prevalence of food addiction was 13.8%, followed by overweight. The presence of 3 or more symptoms for food addiction was observed in 10% of the population without having the clinical significance that determines the presence of the pathology, predominating in the male population and in those under 60 years of age. This presence within the category of obesity can be seen in 10%. It is concluded that almost 6% of the population had food addiction and 10% had 3 or more symptoms typical of the pathology. Including the test in the appointment of patients belonging to the CSPP would allow referral to the psychology team of the institution of those who require it.

Exploring the Discrepancies in Actual and Perceived Benefits of Dietary Supplements Among Obese Patients.

Dietary supplements (DSs) have gained increased popularity for weight loss due to its availability without prescription, relatively low price, and ease of use. Consumers with limited health literacy may not adequately know the benefits and risks associated with DSs. In this project, we found a knowledge gap between reported benefits of major DSs by adults with obesity in the National Health and Nutrition Examination Survey 2003-2014 and those reported in existing DS knowledge databases.

The balance between food and dietary supplements in the general population.

In the past, vitamins and minerals were used to cure deficiency diseases. Supplements nowadays are used with the aim of reducing the risk of chronic diseases of which the origins are complex. Dietary supplement use has increased in the UK over recent decades, contributing to the nutrient intake in the population, but not necessarily the proportion of the population that is sub-optimally nourished; therefore, not reducing the proportion below the estimated average requirement and potentially increasing the number at risk of an intake above the safety limits. The supplement nutrient intake may be objectively monitored using circulation biomarkers. The influence of the researcher in how the supplements are grouped and how the nutrient intakes are quantified may however result in different conclusions regarding their nutrient contribution, the associations with biomarkers, in general, and dose-response associations specifically. The diet might be sufficient in micronutrients, but lacking in a balanced food intake. Since public-health nutrition guidelines are expressed in terms of foods, there is potentially a discrepancy between the nutrient-orientated supplement and the quality of the dietary pattern. To promote health, current public-health messages only advocate supplements in specific circumstances, but not in optimally nourished populations.

Iodine Status of Taiwanese Population in 2013: 10 Years After Changing From Mandatory to Voluntary Salt Iodization.

BACKGROUND: In 2003, Taiwan's iodine policy changed from mandatory to voluntary. The Nutrition and Health Survey in Taiwan (NAHSIT) 2001-2002 for schoolchildren showed adequate iodine nutrition, while NAHSIT 2005-2008 for adults showed the iodine status was at borderline adequacy. OBJECTIVE: To investigate the iodine status of the Taiwanese population from schoolchildren to adulthood 10 years after the change of the salt iodization policy. METHOD: Urinary iodine was measured in samples from subjects in NAHSIT 2013. RESULTS: The median urinary iodine concentration (UIC) of the Taiwanese population aged 6 years and above in 2013 was 96 µg/L, indicating mild iodine deficiency. The median UIC of 6- to 12-year-old schoolchildren was 124 µg/L (interquartile range [IQR]: 92-213 µg/L), and 115 µg/L (IQR: 80-166 µg/L), 125 µg/L (IQR: 74-161 µg/L), 73 µg/L (IQR: 52-131 µg/L), and 78 µg/L (IQR: 52-132 µg/L) in populations aged 13 to 18 years, 19 to 44 years, 45 to 64 years, and ≥65 years, respectively. Declining iodine nutrition in age groups ≥45 years old was noted that the median UIC of populations aged 45 to 64 years and ≥65 years was 99 and 88 µg/L, respectively, in NAHSIT 2005-2008. The median UIC of schoolchildren was not lower than that during the mandatory salt fortification period, but the distribution of urinary iodine levels signified a dietary pattern change. CONCLUSION: Wide-ranging variation in iodine nutrition levels was observed in different age groups. Universal salt iodization, as suggested by the World Health Organization, should be the best strategy to achieve adequate iodine nutrition.

Dietary Supplement Use Was Very High among Older Adults in the United States in 2011-2014.

Background: Dietary supplements (DSs) have the potential to be both beneficial and harmful to health, especially in adults aged ≥60 y, and therefore it is important to monitor the patterns of their use.Objective: This study evaluated DS use by adults aged ≥60 y to characterize the use of DSs, determine the motivations for use, and examine the associations between the use of DSs and selected demographic, lifestyle, and health characteristics.Methods: Data from 3469 older adults aged ≥60 y from the 2011-2014 NHANES were analyzed. DSs used in the past 30 d were ascertained via an interviewer-administered questionnaire in participants' homes. The prevalence of overall DS use and specific types of DSs were estimated. The number of DSs reported and the frequency, duration, and motivation(s) for use were assessed. Logistic regression models were constructed to examine the association between DS use and selected characteristics.Results: Seventy percent of older adults in the United States reported using ≥1 DS in the past 30 d; 54% of users took 1 or 2 products, and 29% reported taking ≥4 products. The most frequently reported products were multivitamin or mineral (MVM) (39%), vitamin D only (26%), and omega-3 fatty acids (22%). Women used DSs almost twice as often as men [adjusted OR (aOR), 1.8; 95% CI: 1.5, 2.3). Those not reporting prescription medications were less likely to take a DS than those reporting ≥3 prescription medications (aOR, 0.4; 95% CI: 0.3, 0.6). The most frequently reported motivation for DS use was to improve overall health (41%).Conclusions: Use of DSs among older adults continues to be high in the United States, with 29% of users regularly taking ≥4 DSs, and there is a high concurrent usage of them with prescription medications.

Changes in dietary glycemic index and glycemic load in Australian adults from 1995 to 2012.

Background: Australians have used the glycemic index (GI) since 1995; however, there are no data on changes in carbohydrate quality over time.Objectives: The aim was to compare average dietary GI and glycemic load (GL), and contributing carbohydrate foods, in the 2 most recent national dietary surveys.Design: Dietary data from adult participants of national nutrition surveys conducted in 1995 (the 1995 Australian National Nutrition Survey; n = 8703) and 2012 (the 2011-2012 National Nutrition and Physical Activity Survey; n = 6278), collected by a single 24-h recall, were analyzed. The differences in mean dietary GI and GL between surveys were compared by using 1-factor ANOVA. The main sources of dietary GL in the 2 surveys were also assessed. Multiple linear regression was performed to examine the contributions of the food groups to interindividual variations in dietary GI and GL.Results: Overall, dietary GI and GL decreased by 5% and 12%, respectively, from 1995 to 2012 (GI on glucose standard: 56.5 ± 6.2 compared with 53.9 ± 6.8, respectively; GL: 153.3 ± 62.1 compared with 135.4 ± 58.5, respectively; both P < 0.001). Breads were the main contributor to GL at both time points. Potatoes and sweetened beverages contributed less, whereas cereal-based dishes contributed more in 2012 than in 1995. The top 20 GL-contributing food groups explained less interindividual variation in dietary GI (R2: 0.376 compared with 0.290) and GL (R2: 0.825 compared with 0.770) in 2012 than in 1995.Conclusion: Although the average dietary GI and GL declined between 1995 and 2012, trends in specific carbohydrate foods suggest that Australians are avoiding potatoes and sugary beverages in favor of a greater variety of carbohydrate foods, particularly cereal products.

Objective: to investigate the prevalence and factors associated with excessive consumption of dietary supplements among professionals working at gyms in Pelotas, Rio Grande do Sul State, Brazil. Methods: this is a cross-sectional study with all local fitness professionals identified in 2012; excessive consumption of dietary supplements was defined as the use of three or more types of supplements simultaneously; multivariate analysis was carried out using Poisson regression with robust variance. Results: 497 professionals were interviewed; the prevalence of excessive consumption of dietary supplements was 10.5% (95%CI 7.9;13.5); there was association with the male sex (PR=3.2; 95%CI 1.6;6.7) and with length of time of dietary supplement consumption ≥4 years when compared to <1 year (PR=2.8; 95%CI 1.7;4.7); lower consumption was found among professionals with higher levels of education, regardless of whether they had a degree in physical education or not (p=0,007). Conclusions: prevalence of excessive consumption of dietary supplements can be considered high and was associated with sociodemographic variables.

Estimating safe maximum levels of vitamins and minerals in fortified foods and food supplements.

PURPOSE: To show how safe maximum levels (SML) of vitamins and minerals in fortified foods and supplements may be estimated in population subgroups. METHODS: SML were estimated for adults and 7- to 10-year-old children for six nutrients (retinol, vitamins B6, D and E, folic acid, iron and calcium) using data on usual daily nutrient intakes from Irish national nutrition surveys. RESULTS: SML of nutrients in supplements were lower for children than for adults, except for calcium and iron. Daily energy intake from fortified foods in high consumers (95th percentile) varied by nutrient from 138 to 342 kcal in adults and 40-309 kcal in children. SML (/100 kcal) of nutrients in fortified food were lower for children than adults for vitamins B6 and D, higher for vitamin E, with little difference for other nutrients. Including 25 % 'overage' for nutrients in fortified foods and supplements had little effect on SML. Nutritionally significant amounts of these nutrients can be added safely to supplements and fortified foods for these population subgroups. The estimated SML of nutrients in fortified foods and supplements may be considered safe for these population subgroups over the long term given the food composition and dietary patterns prevailing in the respective dietary surveys. CONCLUSIONS: This risk assessment approach shows how nutrient intake data may be used to estimate, for population subgroups, the SML for vitamins and minerals in both fortified foods and supplements, separately, each taking into account the intake from other dietary sources.

Serum Vitamin D Level Related to Coffee Consumption in Korean Young Adults Using the 5th Korea National Health and Nutrition Examination Survey

BACKGROUND: Even young adults are highly interested in their osteological health, yet their calcium intake does not match the level of such interest. Increase in bone loss is known to be associated with higher intake of caffeine and coffee consumption among the young Korean is rising steadily. This study was conducted to reveal the relationship between coffee consumption and serum vitamin D level in Korean young adults. METHODS: This study analyzed potential difference in lifestyle and concentration of vitamin D in blood in relation to coffee intake frequency of 2,523 subjects on the basis of data from the 5th Korea National Health and Nutrition Examination Survey. RESULTS: According to the analysis, groups of males, with high income, frequent social activity followed by alcohol consumption and smoking, and high rate of dining out showed a high frequency of coffee consumption. Vitamin D concentration among the groups was 16.2±5.3 mL and 80.3% of them were considered to be vitamin D-deficient. All the groups appeared to have deficiencies compared to males who did not consume caffeine at all. CONCLUSIONS: The practice of having an adequate amount of coffee is needed, and more efforts should be done to improve vitamin D intake among young adults.

Excessive Consumption of Green Tea as a Risk Factor for Periodontal Disease among Korean Adults.

This study was performed to assess the relationship between the amount of green tea that is consumed and periodontitis. It is based on data obtained from the Korea National Health and Nutrition Examination Survey, conducted between 2008 and 2010. A community periodontal index equal to code 3 was defined as moderate periodontitis, and code 4 was defined as severe periodontitis (n = 16,726). Consumption of green tea less than one cup per day was associated with a decreased prevalence of periodontal disease among Korean adults. The association between the consumption of green tea and periodontal disease was independent of various potential confounding factors, such as age, sex, body mass index, smoking, drinking, exercise, metabolic syndrome, frequency of tooth brushing per day, use of secondary oral products, the number of dental examination per year, diabetes, hypertension, and white blood cell count. Adjusted odds ratio and 95% confidence interval of no consumption was 1.360 (1.156, 1.601) when participants with consumption of two times per week ≤ x < 7 times per week was considered as a reference. However, consumption of one or more cups per day increased the prevalence of moderate and severe periodontitis. In conclusion, excessive consumption of green tea may be considered as a risk factor for periodontal disease among Korean adults.

Perfil nutricional e uso de suplementação entre praticantes de musculação e atletas de judô em academias de Campo Grande, MS / Nutritional profile and use of supplementation by bodybuilders and judo athletes in gyms of Campo Grande, MS

Introdução: Avaliar o perfil nutricional e o uso de suplementação entre praticantes de musculação e atletas de judô em academias de Campo Grande, MS. Método: Estudo transversal descritivo com 50 participantes, de ambos os gêneros, entre 18 e 35 anos. Para avaliação do consumo alimentar, foram aplicados inquéritos dietéticos, medindo-se consumo energético e de macronutrientes. Foram realizadas medidas de peso, estatura, pregas cutâneas e circunferência. Para cálculo do percentual de gordura, foi utilizado somatório de três pregas cutâneas. O uso de suplemento foi avaliado por meio de aplicação de questionário. A análise estatística foi realizada com o software SPSS, considerando p<0,05. Resultados: A média de energia consumida pelos praticantes de musculação foi 1768,4 kcal/dia e a média dos valores das necessidades estimadas de energia foi 2445,6 kcal/dia; entre os atletas de judô, foi 1851,1 kcal/dia e 2800,1 kcal/dia, respectivamente. O consumo de carboidratos, proteínas e lipídios foi 50,49%, 20,44% e 29,06% entre os praticantes de musculação e 45,06%, 23,31% e 31,61% entre os judocas, respectivamente. Houve diferença significativa na composição corporal entre os participantes nas variáveis índice de massa corporal, circunferência da cintura, massa magra e massa gorda. A utilização de suplementos ocorreu em 26% dos participantes. Conclusões: A quantidade de energia consumida foi menor do que a necessidade estimada de energia em ambos os grupos e os valores de macronutrientes estavam inadequados. Houve diferença significativa na composição corporal dos participantes, destacando- se percentual elevado de gordura em ambos os grupos. Não houve diferença significativa entre o uso de suplementos entre os grupos.(AU)

Introduction: To evaluate the nutritional status and the use of supplementation by bodybuilders and judo athletes in gyms of Campo Grande, MS. Methods: A descriptive cross-sectional study with 50 participants, of both genders, between 18 and 35 years. Dietary surveys were applied to assess food consumption, evaluating energy consumption and macronutrients. Measures of weight, height, skin folds and circumference were performed. To calculate the percentage of fat was used sum of three skinfolds. The use of supplementation was assessed by questionnaire. Statistical analysis was performed using SPSS software, considering p<0.05. Results: The average power consumed by bodybuilders was 1768.4 kcal/day and the average value of the estimated energy needs was 2445.6 kcal/day; among the judo athletes was 1851.1 kcal/day and 2800.1 kcal/day, respectively. The consumption of carbohydrates, proteins and lipids was 50.49%, 20.44% and 29.06% among bodybuilders and 45.06%, 23.31% and 31.61% among judokas, respectively. There were significant differences in body composition between the participants in variables body mass index, waist circumference, fat mass and lean mass. The use of supplements occurred in 26% of participants. Conclusions: The amount of energy consumed was lower than the estimated energy requirements in both groups and macronutrient values were inadequate. There were significant differences in body composition of the participants, highlighting high percentage of fat in both groups. There was no significant difference between the use of supplements between groups.(AU)

Nationwide survey of nutritional management in an Asian upper-middle income developing country government hospitals: Combination of quantitative survey and focus group discussion.

BACKGROUND & AIMS: The objective of this study was to identify the differences in pattern, process, and management of nutrition care in government hospitals in Thailand (an Asian upper-middle income developing country). METHODS: This is a combination of a quantitative nationwide questionnaire survey and focus group discussions. A total of 2300 questionnaires were sent to government hospitals across Thailand. The responders were divided by routine-nutrition screening/assessment unit vs. non-routine-nutrition screening/assessment unit (RSA vs. NRSA). The comparison between the groups was reported as percentage and cross-sectional odds ratio (CS-OR) with 95% confidence interval (CI). The significant difference was defined as p < 0.05. RESULTS: A total of 814 questionnaires (35.4%) were returned. The three most common tools of RSA were 42% Bhumibol Nutrition Triage (BNT), 21.2% Subjective Global Assessment (SGA) and 20.2% Nutrition Alert Form (NAF). The RSA was significantly higher in proportion for the role of the nurses (RSA vs. NRSA; CS-OR [95% CI]: 68.3% vs. 11.9%; 15.8 [11.1 to 22.7]; p < 0.01), the multidisciplinary team (90.1% vs. 0.4%; 2266 [558 to 1909]; p < 0.01), the nutrition management guidelines (60.6% vs. 2.8%; 53.6 [29.6 to 102.8]; p < 0.01), the nurse-driven enteral feeding protocols (31.7% vs. 17.5%; 2.2 [1.5 to 3.1]; p < 0.01) and preference for hospital formula enteral nutrition (91.4% vs.69.7%; 4.6 [2.9 to 7.4]; p < 0.01). For focus group discussions, the main barrier of RSA implementation was that there was no national recommendation of a screening/assessment tool, inconsistency of policy and reimbursement, and professional and acceptable workload. CONCLUSION: Nutrition screening/assessment tools were found to be varied in Thailand. RSA affected the nutrition management working process and the types of nutrition support. The main barriers of RSA implementation were inconsistency of policy and reimbursement, acceptable workload, and national guidance as regards - screening/assessment tools.
