Purpose: Increased awareness of the importance of dietary fibre has led to increased interest in 'functional' fibre components like digestion-resistant maltodextrin (RMD). This randomized, placebo-controlled, double-blind study assessed the effects of RMD in the colonic transit time (CTT) and defecation characteristics (frequency, stool volume and consistency). Methods: Sixty-six healthy adult volunteers (32 men) who did not have a daily defecation habit had a 7-day run-in period before the 21-day intervention period with RMD or placebo. CTT and segmental CTT (SCTT) were assessed by a single abdominal X-ray film taken at the end of both periods after radiopaque marker ingestion. Defecation characteristics and intestinal functions were also assessed, which were self-reported by patients. Intragroup comparisons were evaluated by Student's paired t test, Bonferroni test and Chi-square test, while time comparisons by analysis of variance (ANOVA) and time-by-treatment interaction by repeated-measures ANOVA. Results: Fifty-seven subjects were assessed for CTT (placebo, n = 28; RMD, n = 29). In the RMD group, the total CTT, left SCTT and rectosigmoidal SCTT decreased significantly compared to baseline ( p < 0.01 each; −13.3, −4.7, −8.7 h, respectively). Significant differences between groups were observed in total CTT and left SCTT. Significant time-by-treatment interaction was observed in the RMD group for stool volume ( p = 0.014), increasing 56 % compared to baseline ( p < 0.01), while remained unchanged in the placebo group. Stool consistency was improved only in the RMD group ( p < 0.01). No adverse effects related to study products were observed. Conclusions: The results show that RMD improved CTT, stool volume, stool consistency and some intestinal functions in a healthy population. [ABSTRACT FROM AUTHOR]

Purpose: This cross-sectional study assesses the relationship between consumption frequencies of food items and high-sensitivity C-reactive protein (hs-CRP) in European children. Methods: Out of the baseline sample ( N = 16.228) of the IDEFICS study, 6.403 children (1.315 boys aged 2 to <6, 1.908 boys aged 6 to <10, 1.204 girls aged 2 to <6 and 1.976 girls aged 6 to <10 years) had hs-CRP measured and the Children's Eating Habits Questionnaire filled, including a food frequency questionnaire. Logistic regression adjusted for body mass index z-score, education of the mother, breast-feeding and self-reported hours of physical activity in a sport club per week was conducted. Results: Mean frequency intake of raw vegetable was lower in boys ( p = 0.022 in young and p = 0.020 in old) and older girls ( p = 0.026) with high hs-CRP concentration, while in younger girls ( p = 0.008) the same occurred with the cooked vegetables. The probability of having higher hs-CRP concentration was significantly associated with having low consumption frequency of vegetables ( p = 0.004 in older boys, raw vegetables; and p = 0.0032 in younger girls, cooked vegetables). Also, honey/jam intake decreased the probability of having higher concentration of hs-CRP, whereas soft drinks with sugar, mayonnaise and cereals milled increased this probability. Conclusions: Out of all food items associated with hs-CRP, frequency intake of vegetables presented more associations across all the analysis. Findings suggest that a high-frequency intake of vegetables is inversely related to an inflammatory status in children. More studies are needed to assess the association between diet and inflammation. [ABSTRACT FROM AUTHOR]

Purpose: Two objectives were investigated: (1) to assess the risk of micronutrient deficiencies in relation to weight status in Indian women with a focus on iron but also including zinc, vitamin A and B vitamins and (2) to compare fractional iron absorption between obese (OB) and normal weight (NW) women. Methods: Part 1 was a cross-sectional study including 146 healthy, middle-class women from Bangalore, India, with a BMI between 19 and 40 kg/m. Anthropometrics and blood pressure were measured, and a fasting blood sample was obtained for the analysis of vitamin and mineral status, hepcidin, blood lipids and glucose. In part 2, 16 OB and 13 NW women consumed a standardized test meal labeled with the stable iron isotope Fe. Incorporation of the iron isotope into erythrocytes was measured 14 days later. In addition, iron status, hepcidin and inflammatory markers were determined. Results: In part 1, compared to NW women, overweight/OB subjects had significantly higher C-reactive protein, serum ferritin, soluble transferrin receptor (sTfR) and hepcidin concentrations ( p < 0.05). The odds ratio for having high sTfR concentrations (i.e., low iron status) with increasing BMI was 1.09 (95 % CI 1.02-1.17). None of the other micronutrients investigated showed any differences between weight status groups. In part 2, fractional iron absorption was significantly lower in the OB group compared to the NW group even after controlling for differences in iron status (10.0 ± 6.5 vs. 16.7 ± 4.6 %; p = 0.038). Conclusions: OB women in Bangalore have an increased risk of low iron status and absorb less dietary iron; however, their risk of other micronutrient deficiencies was similar to NW women. Our results clearly demonstrate the importance of considering the double burden of malnutrition in the planning of prevention strategies especially in transition countries with emerging obesity epidemics.

Purpose: Alkylresorcinols (AR) are phenolic lipids present in the bran of wheat and rye. Plasma AR and their urinary metabolites may be suitable biomarkers of whole-grain (WG) wheat and rye consumption. The objective of this study was to examine plasma AR and urinary AR metabolites in response to WG wheat consumption. Methods: In a randomized crossover study, 19 subjects (10 males, 9 females; BMI 22.0 kg/m; age 26 years) incorporated either 3 servings (48 g) or 6 servings (96 g) of WG wheat daily into their regular diet for 1 week. Subjects completed a 2-week washout period, abstaining from all WG consumption, before each intervention. Fasting blood and 24-h urine were collected before and after each intervention. Plasma AR homologues (C19:0, C21:0, C23:0) were quantified by GC-MS after diethyl ether and solid phase extraction and derivatization. Urinary AR metabolites [3,5-dihydroxybenzoic acid and 3-(3,5-dihydroxyphenyl)-propanoic acid] were determined using HPLC with electrochemical detection after enzymatic deconjugation and ethyl acetate extraction. Results: Urinary total AR metabolites were significantly higher after 6 compared with 3 servings of WG wheat (56 vs. 32 μmol/day, P < 0.001). This dose-response relationship was independent of age, sex, energy intake, and baseline urinary AR metabolite concentration. Plasma total AR tended to be higher after 6 compared with 3 servings of WG wheat (103.0 vs. 86.9 nmol/L), but this difference was not significant ( P = 0.42). Conclusion: The results suggest that urinary AR metabolites from 24-h urine collections may be useful as biomarkers of compliance in intervention studies of WG wheat. [ABSTRACT FROM AUTHOR]

Purpose: ω3 and ω6 fatty acids (FA) may have divergent effects on the development of obesity. We examined the association of baseline erythrocyte ω3 and ω6 FA composition with body weight change and the risk of becoming overweight or obese in the Women's Health Study (WHS) participants. Methods: We identified 534 women who had baseline erythrocyte FA measured and a baseline body mass index (BMI) of 18.5-<25 kg/m. Body weight was updated at a total of six time points during follow-up. Results: Weight gain during a mean of 10.4-year follow-up increased with increasing quartiles of baseline erythrocyte cis ω6 FA, ω6/ω3 ratio, and trans FA while decreased with increasing cis ω3 FA. After multivariable adjustment including total energy intake and physical activity, the weight gain (kg) in the highest versus the lowest quartile was 3.08 versus 2.32 for erythrocyte cis ω6 FA ( p 0.04), 2.07 versus 2.92 for cis ω3 FA ( p 0.08), 2.93 versus 2.05 for ω6/ω3 ratio ( p 0.046), and 3.03 versus 2.27 for trans FA ( p 0.06). Among individual FA, the associations were significant for 18:2ω6, 18:3ω6, and trans 18:1 and marginally significant for 20:3ω6 and trans 18:2. The risk of becoming overweight or obese (defined as BMI ≥25 kg/m at any follow-up time point) increased across increasing ω6/ω3 ratio (multivariable model p 0.04). Conclusions: In this prospective study, we found suggestive evidence that erythrocyte cis ω6 FA may be positively associated, and cis ω3 FA inversely associated with weight gain in initially normal-weight women.

Background: Few studies have linked major dietary nutrient patterns to chronic diseases. Despite the growing evidence of associations between dietary patterns and obesity, we are aware of no study that examined the association between patterns of nutrient intake and obesity. Objective: To identify major nutrient patterns in Iranian adults and investigate their association with general and abdominal obesity. Methods: In this cross-sectional study that was conducted under the framework of the Study on the Epidemiology of Psychological Alimentary Health and Nutrition (SEPAHAN), dietary data were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire in 8691 subjects aged 18-55 years. Complete data of 6724 and 5203 adults were available for general and abdominal obesity, respectively. Data on anthropometric measures were collected through a self-administered questionnaire. General obesity was defined as body mass index ≥ 30 kg/m, and abdominal obesity as waist circumference > 102 cm for men and >88 cm for women. Daily intakes of 38 nutrients and bioactive compounds were calculated for each participant. Factor analysis, followed by a varimax rotation, was applied to derive major nutrient patterns. Results: Three major nutrient patterns were identified: (1) The first pattern was high in fatty acids (including saturated, monounsaturated and polyunsaturated fatty acids), cholesterol, vitamin B, vitamin E, zinc, choline, protein, pyridoxine, phosphorus and pantothenic acid; (2) the second pattern was high in thiamine, betaine, starch, folate, iron, selenium, niacin, calcium, and manganese; and (3) the third pattern was high in glucose, fructose, sucrose, vitamin C, potassium, total dietary fiber, copper and vitamin K. Men in the highest quintile of the second pattern were less likely to be generally obese in the fully adjusted model [odds ratio (OR) 0.39, 95 % confidence interval (CI) 0.20-0.76]. After adjustment for potential confounders, a significant positive association was observed between the third pattern and general obesity among men (OR 1.77, 95 % CI 1.04-3.04), but not women (OR 1.18, 95 % CI 0.74-1.88). No overall association was seen between patterns of nutrient intake and abdominal obesity in both genders. Conclusion: Major nutrient patterns were significantly associated with general, but not abdominal obesity among male participants of the SEPAHAN study. Further studies in other populations, along with future prospective studies, are required to confirm these findings. [ABSTRACT FROM AUTHOR]

Purpose: To prospectively assess the association between sugar-sweetened beverages (SSB), added sugar, and total fructose and serum concentrations of liver enzymes among healthy, reproductive-age women. Methods: A prospective cohort of 259 premenopausal women (average age 27.3 ± 8.2 years; BMI 24.1 ± kg/m) were followed up for up to two menstrual cycles, providing up to eight fasting blood specimens/cycle and four 24-h dietary recalls/cycle. Women with a history of chronic disease were excluded. Alanine and aspartate aminotransferases (ALT and AST, respectively) were measured in serum samples. Linear mixed models estimated associations between average SSB, added sugar, and total fructose intake and log-transformed liver enzymes adjusting for age, race, body mass index, total energy and alcohol intake, and Mediterranean diet score. Results: For every 1 cup/day increase in SSB consumption and 10 g/day increase in added sugar and total fructose, log ALT increased by 0.079 U/L (95 % CI 0.022, 0.137), 0.012 U/L (95 % CI 0.002, 0.022), and 0.031 (0.012, 0.050), respectively, and log AST increased by 0.029 U/L (−0.011, 0.069), 0.007 U/L (0.000, 0.014), and 0.017 U/L (0.004, 0.030), respectively. Women who consumed ≥1.50 cups/day (12 oz can) SSB versus less had 0.127 U/L (95 % CI 0.001, 0.254) higher ALT [percent change 13.5 % (95 % CI 0.1, 28.9)] and 0.102 (95 % CI 0.015, 0.190) higher AST [percent change 10.8 % (95 % CI 1.5, 20.9)]. Conclusions: Sugar-sweetened beverages were associated with higher serum ALT and AST concentrations among healthy premenopausal women, indicating that habitual consumption of even moderate SSB may elicit hepatic lipogenesis.

Purpose: Obesity is a global epidemic affecting around 10 % of 5- to 17-year olds. With the causes for obesity being multifactorial, a better understanding of the influencing factors is essential for effective treatment and prevention programs. The aim of this study was therefore to identify specific risk factors for overweight and obesity in children in Switzerland. Methods: A nationally representative sample of children aged 6-12 years was recruited ( n = 2724). Height and weight were measured to calculate BMI (kg/m). In addition, a questionnaire was distributed to all children asking about their physical activity, media consumption, and dietary habits as well as some parental factors. Results: The prevalence of overweight and obesity in boys was 11.8 and 7.5 %, respectively, and in girls, it was 11.9 and 5.7 %. In univariate analyses, a number of parental, dietary, and activity factors were shown to be associated with BMI category. Based on a multinomial logistic regression, parent nationality and media consumption were the most important factors predicting obesity in boys, while in girls it was parental education, nationality, and physical activity. Conclusion: We have demonstrated that parental nationality and education play an important role in the development of childhood obesity, together with media consumption and physical activity. However, risk factors are also different according to child gender. Thus, an important target group for the treatment and prevention of childhood obesity in Switzerland are immigrant families, and the problem needs to be tackled differently in boys and girls as their risk factors are not the same.

Introduction: Obesity is a chronic, heterogeneous, multifactorial disease, which has sharply increased in prevalence in both developed and developing countries. This study aimed to estimate the prevalence of obesity and to identify socio-demographic risk factors associated with it, with special emphasis on diet. Methods: Nutritional status, demographic characteristics, lifestyle habits, and food consumption patterns derived from a Food Frequency Questionnaire were investigated. Exhaustive exploratory analyses were performed in order to describe dietary patterns, and logistic regression models were used for odds ratio estimation. Results: The study included 4328 subjects, over 18 years old and resident in Cordoba city. The prevalence of overweight and obesity was 34 and 17 %, respectively, with 60 % in men and 45 % in women of BMI ≥ 25. Obesity risk factors were high intake of sodium, refined grains, starchy vegetables, and snacks. A lower risk of overweight and obesity was associated with an adequate, moderate intake of meats, eggs, alcoholic beverages, sugar and sweets, milk, yogurt, and pulses. Conclusions: A high intake of snacks, refined grains, starchy vegetables and sodium and low intake of yogurt, milk, pulses, and whole grains seem to be associated with the emergence and high prevalence of obesity in Cordoba, Argentina.

Background: Neurodevelopmental effects of omega-3 fatty acids and mercury from fish consumption have been characterized in children. In contrast, neurobehavioral outcomes associated with fish are not well studied in adults. Objective: This study of avid seafood consumers on Long Island (NY, USA) sought to define associations between mercury, seafood consumption, omega-3 fatty acids and neurobehavioral outcomes. Methods: A computer-based test system was used to assess neurobehavioral function. Blood total Hg (Hg) and omega-3 index were measured in 199 adult avid seafood eaters, who also completed the neurobehavioral assessment and an extensive food and fish frequency and demographic questionnaire. Results: For most of the outcomes considered, neither Hg nor omega-3 index was associated with neurobehavioral outcomes after adjustment for key confounding variables. Fish consumption, however, was associated with decreased odds of both self-reported fatigue (OR 0.85; 95 % CI 0.72, 1.01) and a constellation of neurologic symptoms (OR 0.79; 95 % CI 0.66, 0.96). Conclusions: Results from our study provide little evidence that omega-3 fatty acids or Hg is associated with cognitive function in adult avid seafood consumers. Larger studies are needed to confirm our finding of associations between fish consumption and decreased self-reported fatigue and neurologic impairment. [ABSTRACT FROM AUTHOR]

Purpose: To compare dietary intake in 1-year-old infants and their parents between families with high and low obesity risk, and to explore associations between infant dietary intake and relative weight. Methods: Baseline analyses of 1-year-old infants ( n = 193) and their parents participating in a longitudinal obesity intervention (Early STOPP) were carried out. Dietary intake and diet quality indicators were compared between high- and low-risk families, where obesity risk was based on parental weight status. The odds for high diet quality in relation to parental diet quality were determined. Associations between measured infant relative weight and dietary intake were examined adjusting for obesity risk, socio-demographics, and infant feeding. Results: Infant dietary intake did not differ between high- and low-risk families. The parents in high-risk families consumed soft drinks, French fries, and low-fat spread more frequently, and fish and fruits less frequently ( p < 0.05) compared to parents in low-risk families. Paternal intake of vegetables and fish increased the odds for children being consumers of vegetables (OR 1.7; 95 % CI 1.0-2.9) and fish, respectively (OR 2.5; 95 % CI 1.4-4.4). Infant relative weight was weakly associated with a high intake of milk cereal drink ( r = 0.15; p < 0.05), but not with any other aspect of dietary intake, obesity risk, or early feeding patterns. Conclusions: At the age of one, dietary intake in infants is not associated with family obesity risk, nor with parental obesogenic food intake. Milk cereal drink consumption but no other infant dietary marker reflects relative weight at this young age. [ABSTRACT FROM AUTHOR]

Purpose: Oxidative stress is closely related to cognitive impairment, and the antioxidant system may be a potential therapeutic target to preserve cognitive function in older adults. Selenium plays an important antioxidant role through selenoproteins. This controlled trial aimed to investigate the antioxidant and cognitive effects of the consumption of Brazil nuts, the best selenium food source. Methods: We enrolled 31 older adults with mild cognitive impairment (MCI) who were randomly assigned to ingestion of Brazil nuts or to the control group. Participants of the treatment group consumed one Brazil nut daily (estimated 288.75 µg/day) for 6 months. Blood selenium concentrations, erythrocyte glutathione peroxidase (GPx) activity, oxygen radical absorbance capacity, and malondialdehyde were evaluated. Cognitive functions were assessed with the CERAD neuropsychological battery. Results: Eleven participants of the treated group and nine of the control group completed the trial. The mean age of the participants was 77.7 (±5.3) years, 70 % of whom were female. We observed increased selenium levels after the intervention, whereas the control group presented no change. Among the parameters related to the antioxidant system, only erythrocyte GPx activity change was significantly different between the groups ( p = 0.006). After 6 months, improvements in verbal fluency ( p = 0.007) and constructional praxis ( p = 0.031) were significantly greater on the supplemented group when compared with the control group. Conclusion: Our results suggest that the intake of Brazil nut restores selenium deficiency and provides preliminary evidence that Brazil nut consumption can have positive effects on some cognitive functions of older adults with MCI.

Purpose: More than 95 % of the body carnitine is located in skeletal muscle, where it is essential for energy metabolism. Vegetarians ingest less carnitine and carnitine precursors and have lower plasma carnitine concentrations than omnivores. Principle aims of the current study were to assess the plasma and skeletal muscle carnitine content and physical performance of male vegetarians and matched omnivores under basal conditions and after l-carnitine supplementation. Results: Sixteen vegetarians and eight omnivores participated in this interventional study with oral supplementation of 2 g l-carnitine for 12 weeks. Before carnitine supplementation, vegetarians had a 10 % lower plasma carnitine concentration, but maintained skeletal muscle carnitine stores compared to omnivores. Skeletal muscle phosphocreatine, ATP, glycogen and lactate contents were also not different from omnivores. Maximal oxygen uptake (VOmax) and workload ( P) per bodyweight (bicycle spiroergometry) were not significantly different between vegetarians and omnivores. Sub-maximal exercise (75 % VOmax for 1 h) revealed no significant differences between vegetarians and omnivores (respiratory exchange ratio, blood lactate and muscle metabolites). Supplementation with l-carnitine significantly increased the total plasma carnitine concentration (24 % in omnivores, 31 % in vegetarians) and the muscle carnitine content in vegetarians (13 %). Despite this increase, P and VOmax as well as muscle phosphocreatine, lactate and glycogen were not significantly affected by carnitine administration. Conclusions: Vegetarians have lower plasma carnitine concentrations, but maintained muscle carnitine stores compared to omnivores. Oral l-carnitine supplementation normalizes the plasma carnitine stores and slightly increases the skeletal muscle carnitine content in vegetarians, but without affecting muscle function and energy metabolism.

Purpose: Few epidemiological studies have assessed the relationship between the traditional Japanese dietary pattern and longitudinal changes in cardiovascular disease risk factors among Japanese people. We designed a 3-year longitudinal study of 980 subjects living in Japan to evaluate how the Japanese dietary pattern is related to longitudinal changes in well-recognized risk factors for cardiovascular disease among apparently healthy Japanese adults. Methods: Dietary consumption was assessed via a validated food frequency questionnaire. Principal component analysis was used to derive three major dietary patterns-'Japanese,' 'sweets-fruits-cooked wheaten food,' and 'Izakaya (Japanese Pub)' from 39 food groups. Results: After adjustment for potential confounders, the mean (95 % confidence interval) for the change per year in diastolic blood pressure for men, systolic blood pressure, and diastolic blood pressure for women related to the 'Japanese' dietary pattern factor score tertiles were 0.89 (0.10, 1.68), 2.25 (0.19, 4.31), and 0.75 (−1.00, 2.50) for the lowest tertile, 0.77 (−0.02, 1.56), 1.01 (−1.13, 3.15), and 0.44 (−1.38, 2.26) for the middle tertile and − 0.04 (−0.81, 0.72), −0.48 (−2.52, 1.56), and −0.77 (−2.51, 0.96) for the highest tertile (trend P value = 0.03, <0.01, and 0.04, respectively). A significant detrimental relationship was found between the 'Izakaya (Japanese Pub)' pattern factor score tertiles and the longitudinal change in serum triglyceride concentration only in men (trend P value = 0.02). Conclusions: Greater adherence to a traditional Japanese diet was independently related to a decreased change every year in diastolic blood pressure in men and women and in systolic blood pressure in women over a 3-year follow-up period. The findings suggest that the 'Japanese' dietary pattern appeared to be related to a fall in blood pressure, which might have a beneficial effect on cardiovascular disease. A randomized trial is required to clarify the underlying mechanism. [ABSTRACT FROM AUTHOR]

Purpose: We compared the effects of a eucaloric moderate-fat diet (18 % protein, 36 % fat, and 46 % carbohydrate), a eucaloric low-fat high-carbohydrate diet (18 % protein, 18 % fat, and 64 % carbohydrate), and a low-calorie (33 % reduced) low-fat high-carbohydrate diet on biomarkers of systemic inflammation. Methods: We randomly assigned 102 participants (age 21-76 years and BMI 19.2-35.5 kg/m) to the three different diets for 6 weeks in a parallel design intervention trial. All foods were provided. Ninety-three participants completed all study procedures; 92 were included in the analyses. Endpoints included plasma C-reactive protein (CRP), interleukin-6 (IL-6), soluble tumor necrosis factor receptors I and II (sTNFRI and II), and adiponectin. Results: In the unadjusted primary analyses, none of the endpoints were differentially affected by the dietary interventions despite the significantly greater reductions in body weight and fat mass in participants consuming the low-calorie low-fat diet compared to the eucaloric diets ( p < 0.001). When including weight change in the model in secondary analysis, adiponectin tended to be increased with weight loss (time × weight change interaction, p = 0.051). Adjusted for weight change, adiponectin was reduced in the groups consuming the low-fat diets relative to the moderate-fat diet ( p = 0.008). No effect of the intervention diets or weight loss on CRP, IL-6, or sTNFRI and II was seen in these secondary analyses. Conclusions: In relatively healthy adults, moderate weight loss had minimal effects on systemic inflammation, and raised plasma adiponectin only modestly. A lower dietary fat and higher carbohydrate content had little impact on measures of systemic inflammation, but reduced adiponectin concentrations compared to a moderate-fat diet. The latter may be of concern given the consistent and strong inverse association of plasma adiponectin with many chronic diseases. [ABSTRACT FROM AUTHOR]

Purpose: Controversy exists regarding whether increasing dairy intake without energy restriction would lead to weight loss. We aimed to compare the potential weight-reducing effects of kefir drink (a probiotic dairy product) and milk in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. Methods: One hundred and forty-four subjects were assessed for eligibility in this single-center, multi-arm, parallel-group, randomized controlled trial. Of these, seventy-five eligible women aged 25-45 years were randomly assigned to three groups, labeled as control, milk, and kefir, to receive an outpatient dietary regimen for 8 weeks. Subjects in the control group received a diet providing a maintenance level of energy intake, containing 2 servings/day of low-fat dairy products, while those in the milk and kefir groups received a weight maintenance diet, containing 2 additional servings/day (a total of 4 servings/day) of dairy products from low-fat milk or commercial kefir drink, respectively. Anthropometric outcomes including weight, body mass index (BMI), and waist circumference (WC) were measured every 2 weeks. Results: Fifty-eight subjects completed the study. Using analysis of covariance models in the intention-to-treat population ( n = 75), we found that at 8 weeks, subjects in the kefir and milk groups had significantly greater reductions in weight, BMI, and WC compared to those in the control group (all p < 0.01). However, no such significant differences were found between the kefir and milk groups. Conclusions: Kefir drink leads to a similar weight loss, compared with milk, in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. However, further studies are warranted. [ABSTRACT FROM AUTHOR]

Purpose: To propose an index for assessing adherence to a Middle Eastern version of the Mediterranean diet as represented by the Traditional Lebanese Mediterranean diet (LMD), to evaluate the association between the LMD and selected European Mediterranean diets (EMD), and to examine socio-demographic and lifestyle correlates of adherence to Mediterranean diet (MD) among Lebanese adults. Methods: Using nationally representative dietary intake data of Lebanese adults, an index to measure Adherence to the LMD was derived. The choice of foods/food groups used for calculating the LMD score was based on results of previous factor analyses conducted on the same dataset. These foods/food groups included fruits, vegetables, legumes, olive oil, burghol, dairy products, starchy vegetables, dried fruits and eggs. Using Pearson's correlation and scores tertiles distributions agreement, the derived LMD index was compared to previously published EMD indexes from Greece, Spain, Italy, France and EPIC/Europe. Results: Fruits, vegetables and olive oil were common denominators to most MD scores. Food groups, specific to the LMD, included burghol, dried fruits, and eggs. The LMD score significantly correlated with the EMD scores, while being closest to the Italian ( r = 0.56) and farthest from the French ( r = 0.21). Percent agreement between scores' tertile distributions and Kappa statistics confirmed these findings. Multivariate linear regressions showed that older age and higher educational levels were associated with increased adherence to all MDs studied. Conclusion: A novel LMD index was proposed to assess adherence to a Middle Eastern version of MD, complementing international efforts to characterize the MD and its association with disease risk.

Purpose: The aim of this study was to establish the role of angiotensin-converting enzyme gene insertion/deletion (ACE I/D) polymorphism in determining obesity or undernutrition in a child population in Romania. Methods: We assessed 293 consecutively hospitalized patients in a tertiary emergency pediatric hospital. The patients were divided, according to body mass index (BMI), into three groups: group I, the control group consisting of 126 children, group II patients with undernutrition (85 patients) and group III patients with obesity (82 patients). ACE I/D polymorphisms were performed in all three patient groups, as well as the measuring of anthropometric parameters [middle upper arm circumference (MUAC), tricipital skinfold thickness (TST)]. All patients also underwent paraclinical evaluations (protein and albumin). The cutoffs criteria for moderate undernutrition were: BMI between −2.0 SD and −3.0 SD, severe undernutrition: BMI <−3.0 SD, moderate obesity: BMI between +2.0 SD and +3.0 SD and severe obesity: BMI >+3.0 SD. Results: We observed that DD genotype (64.7 %) was prevalent in the moderate undernutrition group, while ID (35.3 %) and II genotypes were higher in the subgroup of severe undernutrition, with significant correlations in DD and ID genotype groups between BMI and MUAC, protein and albumin ( p < 0.0001). In the obese group, we observed significant correlations in DD genotype, between BMI and MUAC ( p = 0.0014) and TST, and for II genotype, between BMI and TST ( p = 0.0071). II genotype was associated with severe obesity, while D allele carriers were associated with moderate undernutrition and moderate obesity. Conclusion: BMI, MUAC, TST and serum protein levels are correlated with D allele carriers of ACE genes in children with moderate undernutrition and moderate obesity, whereas II genotype is an unfavorable prognostic factor corresponding to severe obesity and severe undernutrition.

Purpose: The aim of this study was to evaluate whether daily consumption of coffee and tea was associated with components and prevalence of metabolic syndrome (MetS) in the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe cohort study. Methods: A cross-sectional population-based survey including 8,821 adults (51.4 % female) was conducted in Krakow, Poland. Coffee and tea consumption was evaluated using food frequency questionnaires. MetS was defined according to the International Diabetes Federation definition. Linear and logistic regression models were performed to estimate odds ratios and confidence intervals. Results: Among high coffee and tea consumers (3 or more cups/day), high prevalence of female gender, young age, medium-high educational and occupational level, high total energy intake, and smoking habit were found. High coffee drinkers had lower BMI, waist circumference, systolic and diastolic blood pressure, triglycerides, and higher HDL cholesterol than those drinking less than 1 cup/day. In contrast, high tea consumers had lower BMI, waist circumference, but not diastolic blood pressure, which was higher than low drinkers. After adjusting for potential confounding factors, both higher coffee and tea consumption were negatively associated with MetS (OR 0.75, 95 % CI 0.66, 0.86 and OR 0.79, 95 % CI 0.67, 0.92, respectively). Among specific components of MetS, high coffee consumption was negatively associated with waist circumference, hypertension, and triglycerides, whereas tea consumption with central obesity and fasting plasma glucose in women, but not in men. Conclusions: Coffee and tea consumption was negatively associated with MetS and some of its components. [ABSTRACT FROM AUTHOR]

Purpose: To compare total fluid intake (TFI), defined as the sum of water and all other fluid types, assessed with a 24-h dietary (food and fluid) recall with mean TFI assessed with a 7-day fluid-specific record among adolescents and adults. Methods: This repeated cross-sectional study compared TFI as assessed by two fluid assessment instruments using a crossover approach. 290 adolescents (17.3 ± 0.8 years, 50 % boys) and 289 adults (43 ± 9.3 years, 50 % men) from Indonesia completed the study. Results: Significant correlations were observed between fluid intake assessed with the 24-h recall and the 7-day fluid record ( r = 0.333; p < 0.001). The Bland-Altman method, however, showed an underestimation (bias) of mean TFI by a 24-h recall when compared with the 7-day fluid record [mean difference (95 % CI) −382 mL (−299, −465); p < 0.001]. The mean difference also increased with increasing TFI: Mean difference for the lowest and highest quartiles of TFI was 139 versus −1265 mL/day. The 7-day fluid record recorded two (95 % CI −1.9, −2.4; p < 0.0001) extra drinking acts compared with the 24-h recall, whereas the mean volume per drinking act was significantly higher with the 24-h recall [mean difference (95 % CI) 39 mL (31, 47); p < 0.001]. Conclusion: Compared with a 7-day fluid record, a 24-h dietary recall significantly underestimated TFI. Subjects recalled two less drinking acts, while estimating the volume consumed per drinking act to be larger. Since the adequate intakes for total water intake are based on median intakes observed in national surveys that most frequently used the 24-h recall method, they may potentially be underestimated.

Purpose: To describe the intake of water and all other fluids and to evaluate the proportion of adults exceeding the World Health Organisation (WHO) recommendations on energy intake from free sugar, solely from fluids. Methods: A total of 16,276 adults (46 % men, mean age 39.8 years) were recruited in 13 countries from 3 continents. A 24-h fluid-specific record over 7 days was used for fluid assessment. Results: In Spain, France, Turkey, Iran, Indonesia and China, fluid intake was characterised by a high contribution of water (47-78 %) to total fluid intake (TFI), with a mean water intake between 0.76 and 1.78 L/day, and a mean energy intake from fluids from 182 to 428 kcal/day. Between 11 and 49 % of adults exceeded the free sugar WHO recommendations, considering solely fluids. In Germany, UK, Poland and Japan, the largest contributors to TFI were hot beverages (28-50 %) and water (18-32 %). Mean energy intake from fluids ranged from 415 to 817 kcal/day, and 48-62 % of adults exceeded free sugar WHO recommendations. In Mexico, Brazil and Argentina, the contribution of juices and regular sugar beverages (28-41 %) was as important as the water contribution to TFI (17-39 %). Mean energy intake from fluids ranged 565-694 kcal/day, and 60-66 % of the adults exceeded the free sugar WHO recommendation. Conclusions: The highest volumes recorded in most of the countries were for water, mean energy intake from fluids was up to 694 kcal/day, and 66 % of adults exceeded the free sugar WHO recommendation solely by fluids. Actions to create an environment in favour of water consumption and reduce sugar intake from fluids therefore are warranted. [ABSTRACT FROM AUTHOR]

Purpose: To examine the association between dietary glycaemic index (GI) and dietary glycaemic load (GL) with cardiovascular disease (CVD) risk factors in a rural elderly population. Methods: A cross-sectional study was conducted in 343 subjects (60-74 years) residing in a Spanish rural area (Priego de Córdoba). Subjects were selected using stratified random sampling. Food intake was assessed using a validated food frequency questionnaire (FFQ). We assigned GI values to each item of the FFQ to estimate dietary GI and GL. Multivariate linear regression models were fitted to assess the association between GI/GL with CVD risk factors (blood glucose, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, apolipoprotein A1, body mass index, waist circumference and blood pressure). The potential modifying effect of sex, smoking status, diabetes and medication has been explored. Results: A statistically significant inverse association between dietary GI and blood glucose was found in the multivariate model ( p = 0.029): for every 10 unit increment of GI, serum glucose levels decreased by 0.2 units. However, statistical significance was lost after controlling for diabetes or hypoglycaemic medication. In the crude model, dietary GL was associated with triglycerides ( ß for every 10 GL units increase = 0.70, p = 0.005), but statistical significance was lost in the multivariate model ( p = 0.508). No associations were found between dietary GI/GL and the rest of the variables studied. Conclusions: Neither dietary GI nor GL were associated with CVD risk factors in the study population of Priego de Córdoba. Results obtained suggest the necessity to consider the diagnosis of diabetes in these studies. [ABSTRACT FROM AUTHOR]

Purpose: An aberrant gut microbiome has been suggested to contribute to the worldwide epidemic of obesity. In animal models, the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) induced upregulation of genes involved in energy homoeostasis, reduced body fat and altered the serum (S) lipoprotein profile. In our previous report, feeding LF19 to infants during weaning impacted the global plasma metabolome. LF19 lowered palmitoleic acid, a monounsaturated fatty acid associated with hypertriglyceridemia and increased visceral adiposity. Therefore, we assessed if feeding LF19 from 4 to 13 months of age would have long-term effects on body composition, growth and metabolic markers. Methods: Of 179 children included in our baseline study, 120 entered the follow-up at 8-9 years of age, n = 58 in the probiotic and n = 62 in the placebo group. Body composition was measured using dual energy X-ray absorptiometry. Anthropometrics of the child and accompanying parent(s) were assessed. S-lipids, insulin, glucose and transaminases were determined after overnight fasting. Results: LF19 did not affect body mass index z-score, sagittal abdominal diameter, fat-free mass, fat mass index, truncal fat %, android or gynoid fat % and had no long-term impact on any of the assessed metabolic markers ( p > 0.05). Conclusion: Feeding LF19 during infancy did not modulate body composition, growth or any of the assessed metabolic markers at school age. The steady increase in probiotic products targeting infants and children calls for long-term follow-up of initiated probiotic intervention studies. [ABSTRACT FROM AUTHOR]

Purpose: Dietary pattern analysis may uncover the joint effects of multiple dietary components on bone health, but such research is scarce and targets mostly adults. Methods: We quantified prospective associations between dietary patterns and bone mineral density (BMD) in 1,007 adolescents of a cohort born in 1990 and recruited at schools in Porto during the 2003/2004 school year. Forearm BMD was measured using dual-energy X-ray absorptiometry. Participants' dietary patterns were classified 'Healthier', 'Dairy products', 'Fast food and sweets' and 'Lower intake' according to previously identified patterns obtained in a larger sample of 1,489 participants using the K-means method. Using dietary patterns at 13 years old as the main exposure, associations were estimated cross-sectionally (with BMD at the age of 13) and prospectively (with annual BMD variation between 13 and 17 years), using linear regression coefficients adjusted for height, weight, energy intake and, in girls, for menarche age. Results: No significant associations between the a posteriori dietary patterns identified and mean BMD at 13 were found. However, among girls, adherence to a pattern characterized by low intake of energy and all food groups was negatively associated with annual BMD variation between 13 and 17 years [adjusted coefficient (95 % CI) −0.451 (−0.827; −0.074) mg·cm·year]. Conclusions: Although results showed that, in girls, adherence to a 'Lower intake' dietary pattern is associated with lower annual BMD variation throughout adolescence, overall, there were no consistent associations between dietary patterns and forearm BMD in adolescents.

Purpose: There is evidence that dietary habits contribute to the presence and severity of non-alcoholic fatty liver disease (NAFLD). The aim of the present study was to explore any associations between consumption of grains and the development and severity of NAFLD. Methods: Seventy-three consecutive NAFLD patients were enrolled. Additionally, 58 controls matched for age, sex and body mass index with 58 patients were also included. Consumption of grains was estimated through a semi-quantitative food frequency questionnaire. Medical history, anthropometric indices, body composition analysis, physical activity data, biochemical and inflammatory markers were available for all the participants. Liver stiffness measurement by transient elastography was performed in 58 and liver biopsy in 34 patients. Results: In patients, consumption of whole grains was associated with lower abdominal fat level ( β = −0.24, p = 0.02) and lower levels of insulin resistance index ( β = −0.28, p = 0.009), while it also correlated inversely with interleukin-6 levels ( ρ = −0.23, p = 0.05). Consumption of whole grains was associated with lower likelihood of having histological steatohepatitis (OR 0.97, 95 % CI 0.94-1.000), after adjusting for sex and energy intake, but the association became weaker after further adjusting for abdominal fat or interleukin-6 levels. In the case-control analysis, consumption of refined grains was associated with higher odds of having NAFLD (OR 1.021, 95 % CI 1.001-1.042), after adjusting for age, sex, energy intake, abdominal fat level, HOMA-IR, LDL, adiponectin and TNF-α. Conclusions: Although refined grain consumption increased the likelihood of having NAFLD, whole-grain consumption favorably affected clinical characteristics of patients with NAFLD and tended to be associated with less severe disease.

Background: Previous studies have shown that total antioxidant capacity (TAC) of typical diets is associated with higher plasma TAC and antioxidant enzyme activities. At present, however, little is known for the association between dietary TAC and inflammatory biomarkers. Aim: The present study was designed to examine the association between dietary TAC and inflammatory biomarkers in a group of overweight/obese postmenopausal women, a population with high cardiovascular disease (CVD) risk, during a 9-month period. Methods: Thirty-five postmenopausal, overweight or obese, but apparently healthy women aged 40-70 years were recruited for a 9-month observational study. Seven-day food records and 12-h fasting blood samples were collected at baseline and at the end of the study for dietary and plasma biomarker assessments. Dietary TAC was calculated theoretically for taking account of both diet and dietary supplements, and energy-adjusted values were obtained using residual method. Results: At baseline, subjects consuming diets with high dietary TAC had lower levels of plasma C-reactive protein (CRP) and monocyte chemoattractant protein-1 ( p < 0.05) compared with those with low dietary TAC. Over the 9-month period, change in dietary TAC had a negative partial correlation with plasma CRP levels ( p < 0.01) when age, ethnicity, and changes in BMI, blood total cholesterol and triglyceride were adjusted. Conclusions: Findings suggest that consumption of diets high in TAC are inversely associated with plasma CRP levels cross-sectionally and dynamically and may contribute to CVD protection.

Background: In cohort studies, often only one baseline measurement of dietary intake is available. This may underestimate the strength of the association with cardiovascular diseases (CVD). Objective: The main objective is to compare the strength of the association of a Mediterranean style diet with CVD using one baseline measurement of diet versus three repeated measurements over a 10-year period. Design: We used dietary and lifestyle data of three rounds of the Doetinchem Cohort Study. At baseline, 7,769 persons aged 20-65 years were examined. Diet was assessed with a 178 item validated food-frequency questionnaire and operationalized with the Mediterranean Diet Score (MDS) ranging from 0 to 9. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95 % confidence intervals (CI). Analyses were adjusted for age, sex, and repeated measurements of smoking, sports, total energy intake, and educational level. Results: Comparing an MDS of ≥5.5-9 to an MDS of 0-<3.5, baseline MDS was associated with a 23 % lower risk [HR 0.77 (95 % CI 0.53-1.11)] and the updated mean with a 35 % lower risk [HR 0.65 (0.43-0.97)] of a composite of fatal CVD, nonfatal myocardial infarction, and stroke (composite CVD). For fatal CVD, baseline MDS was associated with a 13 % lower risk [HR 0.87 (0.36-2.07)] and the updated mean with a 56 % lower risk [HR 0.44 (0.19-1.05)]. Conclusion: The strength of the association between a Mediterranean style diet and CVD is likely underestimated because most studies so far used only one baseline measurement. [ABSTRACT FROM AUTHOR]

Purpose: Faster eating is positively associated with body mass index in apparently healthy Japanese populations. In the present study, we examined the associations between self-reported rate of eating and visceral and subcutaneous fat areas in apparently healthy middle-aged Japanese men. Methods: We conducted a cross-sectional study of men who participated in health checkups in Japan. We removed participants who were diagnosed with metabolic diseases by the time of their health checkups. A total of 320 subjects aged 30-64 years (mean ± standard deviation, 47.4 ± 8.6 years) were selected. We compared the associations between rate of eating and various clinical parameters including visceral and subcutaneous fat areas, using analysis of covariance (ANCOVA), which was adjusted by age and lifestyle factors such as alcohol intake, energy intake, smoking, and physical activity. Multivariate logistic regression analyses (MLRA) were performed with visceral fat area (cm) as the dependent variable and independent variables that included self-reported rate of eating. Results: Tukey's multiple test following ANCOVA showed that self-reported rate of eating was positively associated with visceral fat area (cm), but not with subcutaneous fat area (cm). MLRA showed that the odds ratio of rate of eating for visceral fat area in tertile (T) 3 (>100 cm) compared with T1 (≤70 cm) was 1.99 (95 % CI 1.40-2.90, P < 0.01), and the association remained after adjustment for the subcutaneous fat area. Conclusions: The present results show that self-reported faster eating is positively associated with visceral fat accumulation, independently of subcutaneous fat accumulation, in apparently healthy Japanese men.

Purpose: To evaluate how long-term dietary intake of long-chain n-3 polyunsaturated fatty acids (LCn-3 PUFAs), estimated by repeated food frequency questionnaires (FFQs) over 15 years, is correlated with LCn-3 PUFAs in adipose tissue (AT). Methods: Subcutaneous adipose tissue was obtained in 2003-2004 (AT-03) from 239 randomly selected women, aged 55-75 years, after completion of a 96-item FFQ (FFQ-03). All participants had previously returned an identical FFQ in 1997 (FFQ-97) and a 67-item version in 1987-1990 (FFQ-87). Pearson product-moment correlations were used to evaluate associations between intake of total and individual LCn-3 PUFAs as estimated by the three FFQ assessments and AT-03 content (% of total fatty acids). Results: FFQ-estimated mean relative intake of LCn-3 PUFAs (% of total fat intake) increased between all three assessments (FFQ-87, 0.55 ± 0.34; FFQ-97, 0.74 ± 0.64; FFQ-03, 0.88 ± 0.56). Validity, in terms of Pearson correlations between FFQ-03 estimates and AT-03 content, was 0.41 (95 % CI 0.30-0.51) for total LCn-3 PUFA and ranged from 0.29 to 0.48 for individual fatty acids; lower correlation was observed among participants with higher percentage body fat. With regard to long-term intake estimates, past dietary intake was also correlated with AT-03 content, with correlation coefficients in the range of 0.21-0.33 and 0.21-0.34 for FFQ-97 and FFQ-87, respectively. The correlations were improved by using average estimates from two or more FFQ assessments. Exclusion of fish oil supplement users (14 %) did not alter the correlations. Conclusion: These data indicate reasonable validity of FFQ-based estimates of long-term (up to 15 years) LCn-3 PUFA intake, justifying their use in studies of diet-disease associations.

Background: Iodine fortification programs have been applied in many iodine deficient regions. Iodine excess is also unfavourable, and it is recommended to monitor iodine status by measuring urinary iodine concentration (UIC). The number of samples needed in such monitoring depends on the variation in UIC. However, it is not known if variation in UIC differs according to iodine levels. Aim and method: We aimed to describe the effect of an iodisation program on the individual and group-based variation in UIC in spot urine samples. Group 1 (G1, n = 16) was studied before, and group 2 (G2, n = 21) was studied after an iodine fortification program was implemented. Individual urine samples were collected monthly for one year, 13 samplings. Results: G1s (207 samples) median (interquartile range) UIC was 50 (37-67) μg/L, and G2 (265 samples) was 98 (69-139) μg/L. Median individual coefficient of variation (CV) was 38 % in G1 and 40 % in G2 ( p = 0.55), whereas the group-based CV was 50 % in G1 and 53 % in G2. No trend was seen between mean UIC and variation in UIC, neither at the individual ( p = 0.36) nor at the group level ( p = 0.43). Based on data from both groups, approximately 100 samples were needed to reliably estimate the UIC in a population. Conclusion: In two groups studied before and after an iodine fortification program was implemented and with different UIC levels, variation in UIC was comparable both at the individual level and according to UIC level. When mild iodine deficiency is corrected, the number of samples needed to reliably estimate the UIC in a population is unaffected. [ABSTRACT FROM AUTHOR]

Purpose: To assess vitamin D status in children aged 2-220 months in northeastern Italy (latitude 46°). Serum 25-hydroxyvitamin D (25OHD) concentration was assessed in 93 children afferent to the Pediatric Department of the Hospital of Udine. Methods: Vitamin D status was defined as follows: sufficient with serum 25OHD between 50 and 250 nmol/l (level 4); insufficient between 37.5 and 50 nmol/l (level 3); deficient less than 37.5 nmol/l (level 2); severely deficient if less than 12.5 nmol/l (level 1). We investigated the potential risk factors of vitamin D deficit. Results: We found that six children (6.4%) had level 1, 36 (38.7%) had level 2, 9 (9.7%) had level 3, and only 45.2% had sufficient level of 25OHD. Immigrate children had a higher risk for vitamin D deficiency if compared with Italians: 75% of non-Italian children had an insufficient 25OHD level compared with 47.0% of Italian children ( p = 0.0036). There was a marked seasonal effect on 25OHD level: when plasma sample was withdrawn between November and May, only 29.4% of children showed sufficient vitamin D level, while 70.5% was insufficient ( p < 0.0001). Among the obese children, 9.0% had sufficient level of 25OHD with 90% being deficient ( p = 0.01). We did not find any significant difference in vitamin D status among children in different age groups. Conclusion: Vitamin D deficiency is common in children living in northeastern Italy. The risk factors were winter season for blood withdrawal, non-Caucasian race, and obesity. These high-risk groups should be targeted for screening and educated about the need of sunlight exposure.

Aim: To evaluate the effect of the daily intake of a fruit & vegetable soup with high in vitro bioaccessibility of carotenoids on β-carotene and lycopene serum concentrations. Methods: Fourteen healthy young men (24 ± 1 years) received 300 mL/day of a carrot, tomato, and broccoli soup, containing 3.9 mg β-carotene and 4 mg lycopene, for 4 weeks followed by a 4-week washout period. The serum carotenoid response and oxidative markers were analyzed after 3 and 4 weeks of soup consumption and after a 4-week washout. Results: The in vitro bioaccessibility of β-carotene and lycopene was 55 and 43%, respectively, in the soup. Serum β-carotene concentrations were significantly higher than baseline (0.33 ± 0.05 μmol/L) after 3 weeks (0.69 ± 0.06 μmol/L) and 4 weeks (0.78 ± 0.10 μmol/L) of soup consumption ( P < 0.001). Serum lycopene was also significantly higher compared with baseline levels (0.26 ± 0.08-0.56 ± 0.04 μmol/L and 0.60 ± 0.04 μmol/L, after 3 and 4 weeks, respectively) ( P < 0.001). Although the highest concentration of both carotenoids was found after 4 weeks, the levels were not statistically different from the levels at 3 weeks. A 4-week washout significantly decreased serum carotenoid concentrations, although only β-carotene returned to baseline. Glutathione peroxidase (GPx) increased significantly after soup supplementation compared with baseline, while superoxide dismutase was significantly lower only after 3 weeks. Glutathione reductase, lipid, protein, and DNA oxidative markers remained unchanged. Conclusions: The soup contributed to increasing the concentration of each carotenoid by more than 100% after 3 and 4 weeks of consumption, the maximum increase being observed after 4 weeks. Oxidative markers did not show any variation except for GPx. Serum lycopene half-life was longer than that of β-carotene, which may be important for studies evaluating both carotenoids.

Purpose: The hypothesis of this clinical study was to determine whether glucocorticoid use and immobility were associated with in-hospital nutritional risk. Methods: One hundred and one patients consecutively admitted to the medical wards were enrolled. Current medical conditions, symptoms, medical history, eating and drinking habits, diagnosis, laboratory findings, medications, and anthropometrics were recorded. The Nutrition Risk Score 2002 (NRS-2002) was used as a screening instrument to identify nutritional risk. Results: The results confirmed that glucocorticoid use and immobility are independently associated with nutritional risk determined by the NRS-2002. Constipation could be determined as an additional cofactor independently associated with nutritional risk. Conclusions: Glucocorticoid treatment, immobility, and constipation are associated with nutritional risk in a mixed hospitalized population. The presence of long-time glucocorticoid use, immobility, or constipation should alert the clinician to check for nutritional status, which is an important factor in mortality and morbidity.
