Análisis de factores de riesgo cardiometabólicos y nutricionales en pacientes diabéticos tipo 2 e hipertensos esenciales usuarios de atención privada y pública / Analysis of cardiometabolic and nutritional risk factors in patients with diabetes type 2 and essential hypertension users of private and public care

La enfermedad cardiovascular es una de las principales causas de morbimortalidad en Chile, según resultados entregados por la Encuesta Nacional de Salud 2017 un 3,3% de la población ha presentado un infarto agudo al miocardio, un 2,6% reporta haber sufrido un ataque cerebrovascular, el 74% de los chilenos presenta obesidad y un 87% sedentarismo, siendo la diabetes mellitus tipo 2 (DM2) con un 12% y la hipertensión arterial con un 28% resultados que preocupan por su importante incremento. La investigación tuvo un diseño observacional de corte transversal. Se realizó en 69 pacientes con DM2 e hipertensos esenciales, entre 40 y 80 años de edad, pertenecientes al Sistema salud municipal (SMS) y privado (SPS) en la ciudad de Iquique. Se realizó encuesta alimentaria, medición antropométrica y exámenes bioquímicos y presión arterial. Al analizar ambos grupos se destaca los siguientes resultados: actividad física 17,24% SPS y 42,5% en SSM, presión arterial controlada 55,2% SPS y 87,5% en SSM, control de hemoglobina glicosilada 26,9% SPS y 52,5% en SSM, colesterol total alterado 17,9% SPS y 45% en SSM, síntomas depresivos 96,5% SPS y 26,3% en SSM. Se evidenció una prevalencia de mal nutrición por exceso de un 89,7% SPS y 95% SSM, riesgo cardiovascular (RCV) según circunferencia de cintura (CC) 96,5% SPS y 92,3% SSM. En relación a la encuesta alimentaria se observó que un 44,8% en usuarios SPS y 52,5% de SSM presentaron consumo alimentario hipercalórico. Los usuarios de atención privada y pública presentaron factores de riesgo cardiovascular, donde destacan la obesidad, sedentarismo y RCV según CC. Al comparar ambos grupos los usuarios SPS presentan menor control metabólico de su enfermedad y factores de riesgo cardiovascular aumentados en relación a los usuarios SSM.

Cardiovascular disease is one of the main causes of morbidity and mortality in Chile, according to the results provided by the 2017 National Health Survey, 3.3% of the population has presented acute myocardial infarction, 2.6% reported have suffered a cerebrovascular accident, 74% of Chileans are obese and 87% have sedentary behavior, belonging to type 2 diabetes mellitus (DM2) into 12% and arterial hypertension into 28%, alarming results due to their significant increase. The research had a cross-sectional observational study design. 69 patients with DM2 and essential hypertensive patients, between 40 and 80 years of age were studied, belonging to the municipal (SSM) and private (SPS) health systems in the city of Iquique. A food intake survey, anthropometric measurements, and biochemical and blood pressure tests were taken. When analyzing both groups, the following results stand out: physical activity 17.24% in SPS and 42.5% in SSM, controlled blood pressure 55.2% in SPS and 87.5% in SSM, controlled glycosylated hemoglobin 26.9% in SPS and 52.5% in SSM, altered values of total cholesterol 17.9% in SPS and 45% in SSM, depression symptoms 96.5% in SPS and 26.3% in SSM. Prevalence of malnutrition due to excess 89.7% in SPS and 95% in SSM, cardiovascular risk (RCV) according to waist circumference (CC) 96.5% in SPS and 92.3% in SSM were evidenced. In relation to the food intake survey, it was observed that 44.8% of SPS users and 52.5% of SSM users consume hypercaloric diet. The users of private and public care presented cardiovascular risk factors, where the obesity, sedentary lifestyle and RCV related to CC stand out. When comparing both groups, SPS users have less control of their disease in relation to SSM users.

Low nutritional status links to the prevalence of pre-metabolic syndrome and its cluster in metabolically high-risk Korean adults: A cross-sectional study.

ABSTRACT: Diet plays a crucial role as a modifiable risk factor related to the development of metabolic syndrome (MetS) and its cluster. Constitution type of traditional Korean medicine has shown accuracy to predict the risk for MetS. We attempted to examine the association between nutritional status, pre-MetS, and its cluster in Korean adults by their constitution type.Participants aged 30 to 55 years who had no cancer or cardiovascular diseases (CVDs) were assigned to join in the present study. Pre-MetS was defined as ≥2 of the following factors: abdominal obesity; elevated triglycerides (TG); reduced high-density lipoprotein cholesterol (HDL-C); elevated blood pressure (BP); and elevated fasting plasma glucose (FPG). Constitution type was categorized into Tae-Eumin (TE) or non-TE. Dietary assessment of the subjects were surveyed using a short-form of the food frequency questionnaire (FFQ) and the nutrition quotient (NQ), which uses 4 factors, namely, balance, diversity, moderation, and dietary behavior.A total of 986 subjects were evaluated by constitution type with MetS status. Of these subjects, 48.6% had pre-MetS, 89.5% were obese and had the highest waist circumference (WC) in Pre-MetS TE. BP, FPG, TG were higher, while HDL-C was lower, than normal TE or non-TE both in Pre-MetS TE and non-TE. The prevalence of pre-MetS was positively associated with lower status of dietary behavior (odds ratio [ORs]: 2.153, 95% confidence interval [CI]: 1.179-3.931) while negatively related to higher vegetables and fruits intakes (ORs: 0.594, 95% CI: 0.359-0.983) in TE. Lower status of NQ had about 2 times higher risk of Pre-MetS (ORs: 1.855, 95% CI: 1.018-3.380) and abdominal obesity (ORs: 2.035, 95% CI: 1.097-3.775) in TE compared with higher status of NQ after controlling for covariates.Poor diet was a key contributor to the development of Pre-MetS and abdominal obesity in Korean adults with TE. Customized nutrition care and integrated medicinal approaches are strongly suggested to conduct optimal preventive care for people who are vulnerable to health risk.

Derivation and Validation of a Total Fruit and Vegetable Intake Prediction Model to Identify Targets for Biomarker Discovery Using the UK National Diet and Nutrition Survey.

BACKGROUND: Dietary assessments in research and clinical settings are largely reliant on self-reported questionnaires. It is acknowledged that these are subject to measurement error and biases and that objective approaches would be beneficial. Dietary biomarkers have been purported as a complementary approach to improve the accuracy of dietary assessments. Tentative biomarkers have been identified for many individual fruits and vegetables (FVs), but an objective total FV intake assessment tool has not been established. OBJECTIVES: To derive and validate a prediction model of total FV intake (TFVpred) to inform future biomarker studies. METHODS: Data from the National Diet and Nutrition Survey (NDNS) were used for this analysis. A modeling group (MG) consisting of participants aged >11 years from the NDNS years 5-6 was created (n = 1746). Intake data for 96 FVs were analyzed by stepwise regression to derive a model that satisfied 3 selection criteria: SEE ≤80, R2 >0.7, and ≤10 predictors. The TFVpred model was validated using comparative data from a validation group (VG) created from the NDNS years 7-8 (n = 1865). Pearson's correlation coefficients were assessed between observed and predicted values in the MG and VG. Bland-Altman plots were used to assess agreement between TFVpred estimates and total FV intake. RESULTS: A TFVpred model, comprised of tomatoes, apples, carrots, bananas, pears, strawberries, and onions, satisfied the selection criteria (R2 = 0.761; SEE = 78.81). Observed and predicted total FV intake values were positively correlated in the MG (r = 0.872; P < 0.001; R2 = 0.761) and the VG (r = 0.838; P < 0.001; R2 = 0.702). In the MG and VG, 95.0% and 94.9%, respectively, of TFVpred model residuals were within the limits of agreement. CONCLUSIONS: Intakes of a concise FV list can be used to predict total FV intakes in a UK population. The individual FVs included in the TFVpred model present targets for biomarker discovery aimed at objectively assessing total FV intake.

Carbohydrate knowledge, dietary guideline awareness, motivations and beliefs underlying low-carbohydrate dietary behaviours.

To explore the factors (including knowledge and attitude) influencing the decision to follow a low-carbohydrate diet (LCD) or not in a sample of the UK population. An online questionnaire was distributed electronically to adults who had either followed LCD or not (February-December 2019). Demographics and self-reported "LCD-status" (current, past and non-follower) were collected. Multivariable linear regression was used with carbohydrate knowledge, dietary guideline agreement and theory of planned behaviour (TPB) constructs (all as predictors) to explain the intention to follow a LCD (outcome). Respondents (n = 723, 71% women, median age 34; 85% white-ethnicity) were either following (n = 170, 24%) or had tried a LCD in the preceding 3 months (n = 184, 25%). Current followers had lower carbohydrate knowledge scores (1-2 point difference, scale - 11 to 11) than past and non-followers. A majority of current LCD followers disagreed with the EatWell guide recommendations "Base meals on potatoes, bread, rice and pasta, or other starchy carbohydrates. Choose whole grains where possible" (84%) and "Choose unsaturated oils and spreads and eat in small amounts such as vegetable, rapeseed, olive and sunflower oils" (68%) compared to past (37%, 10%, respectively) and non-followers (16%, 8%, respectively). Weight-loss ranked first as a motivation, and the internet was the most influencial source of information about LCDs. Among LCD-followers, 71% reported ≥ 5% weight loss, and over 80% did not inform their doctor, nurse, or dietitian about following a diet. Approximately half of LCD followers incorporated supplements to their diets (10% used multivitamin/mineral supplements), despite the restrictive nature of the diet. TPB constructs, carbohydrate knowledge, and guideline agreement explained 60% of the variance for the intention to follow a LCD. Attitude (std-ß = 0.60), perceived behavioural control (std-ß = 0.24) and subjective norm (std-ß = 0.14) were positively associated with the intention to follow a LCD, while higher knowledge of carbohydrate, and agreeing with national dietary guidelines were both inversely associated (std-ß = - 0.09 and - 0.13). The strongest primary reason behind UK adults' following a LCD is to lose weight, facilitated by attitude, perceived behavioural control and subjective norm. Higher knowledge about carbohydrate and agreement with dietary guidelines are found among people who do not follow LCDs.

Association between Infant and Young Child Feeding (IYCF) Indicators and the Nutritional Status of Children (6-23 Months) in Northern Ghana.

Although recommended infant and young child feeding (IYCF) practices have been found to be protective against undernutrition in some settings, there is no finality yet due to inconsistencies in the literature. A cross-sectional survey of 581 mother-child pairs was conducted in northern Ghana in June 2018. The association between IYCF indicators and child undernutrition (stunting and wasting) were assessed. The descriptive analysis showed that 66.4% of the children (6-23 months) were introduced to complementary feeding in a timely manner, 69.4% met the minimum meal frequency, and 38.9% met the minimum acceptable diet daily. The prevalence of stunting, wasting, underweight and overweight was 33.2%, 14.1%, 27% and 2.6%, respectively. From the multivariable binary logistic regression, child gender, child age group and source of power for lighting the household were significantly associated with wasting. Intake of iron-rich foods, child age group, and maternal height were significantly associated with stunting after adjusting for confounders. The prevalence of the compliance with IYCF indicators was relatively high. None of the individual IYCF indicators showed significant association with undernutrition, except intake of iron-rich foods for stunting. Nutrition-specific interventions targeted at improving IYCF practices, dietary diversification and intake of nutrient-rich meals, should be adopted and scaled up to address undernutrition in northern Ghana.

The association of dry eye syndrome and psychiatric disorders: a nationwide population-based cohort study.

BACKGROUND: Several previous studies reported a greater prevalence of dry eye syndrome (DES) among patients with psychiatric diseases. The aim of this study is to investigate the prevalence and risk factors of DES in patients with psychiatric disorders (PD) using nationwide population-based data in Taiwan. METHODS: This population-based cohort study retrospectively identified patients with PD from 1997 to 2011. Patients with both PD and DES served as the DES cohort, and PD patients without DES comprised the non-DES cohort. PD was defined as a diagnosis of PD (ICD-9-CM 290-319) made by psychiatrists only, with at least three consecutive outpatient visits or at least one inpatient visit. DES was defined as a diagnosis of DES (ICD-9-CM 375.15) and a prescription for an eye lubricant (anatomical therapeutic chemical code, ATC code: S01XA). The main outcome measures were the prevalence of DES in these patients and associated risk factors. RESULTS: A total of 75,650 patients with PD (3665 in the DES cohort and 71,985 in the non-DES cohort) were included in the final analysis. The majority of patients in the DES group were women (72.6%), compared the non-DES group (57.8%). The mean age of patients in the DES cohort was 62.2 ± 14.9, which was significantly older than those in the non-DES group (50.9 ± 17.5). The patients with DES had a significantly greater likelihood of having dementia, bipolar disorder, depression, and neurotic disorders. Conditional regression analyses revealed that patients with dry eye disease were more likely to have schizophrenia (OR = 1.34), bipolar disorder (OR = 1.9), depression (OR = 1.54), and neurotic disorders (OR = 1.62). In addition, patients with DES were more likely to use 1st generation anti-psychotics (OR = 1.28) and had a lower risk of using 2nd generation anti-psychotics (OR = 0.64). CONCLUSION: The study demonstrated that among PD patients, DES is highly prevalence in certain subtypes of PD, such as depression, bipolar disorder, and neurotic disorders, after adjusting for the comorbidities.

A prospective study of coffee and tea consumption and the risk of glioma in the UK Biobank.

BACKGROUND: Coffee and tea have been hypothesised to reduce the risk of some cancers; however, their impact on glioma is less well studied. METHODS: We examined associations between self-reported intake of tea and coffee in relation to glioma risk in the UK Biobank. We identified 487 incident glioma cases among 379,259 participants. Hazard ratios (HR) and 95% confidence intervals (CI) for glioma according to caffeinated beverage consumption were calculated using Cox proportional hazards regression with adjustment for age, gender, race and education; daily cups of tea or coffee were included in models considering the other beverage. RESULTS: Consuming 4 or more cups of tea was associated with reduced risk of glioma when compared to no tea consumption (HR = 0.69; 95% CI, 0.51-0.94). A significant inverse association was observed for glioblastoma (HR = 0.93 per 1 cup/d increment; 95% CI, 0.89-0.98) and among males for all gliomas combined (HR = 0.95 per 1 cup/d increment; 95% CI, 0.90-1.00). A suggestive inverse association was also observed with greater consumption of coffee (HR = 0.71; 95% CI, 0.49-1.05 for >4 versus 0 cups/d). Results were not materially changed with further adjustment for smoking, alcohol and body mass index. Associations were similar in 2-year and 3-year lagged analyses. CONCLUSIONS: In this prospective study, we found a significant inverse association between tea consumption and the risk of developing glioma, and a suggestive inverse association for the consumption of coffee. Further investigation on the possible preventive role of caffeine in glioma is warranted.

Nutritional status of Tajik children and women: Transition towards a double burden of malnutrition.

The double burden of malnutrition, an emerging concern in developing countries, can exist at various levels: individual, household, and population. Here, we explore the nutritional status of Tajik women (15-49 years) and children (5-59 months) focusing on overweight/obesity along with undernutrition (underweight, stunting, and micronutrient deficiencies). For this, nutritional markers (haemoglobin (Hb), transferrin receptor (TfR), serum ferritin (Sf), retinol binding protein (RBP), vitamin D, serum folate, and urinary iodine), height, and weight were assessed from 2,145 women and 2,149 children. Dietary intake, weaning, and breastfeeding habits were recorded using a 24-hr recall and a questionnaire. Overweight (24.5%) and obesity (13.0%) are increasing among Tajik women compared with previous national surveys (2003 and 2009). Prevalence of iron deficiency and anaemia was 38.0% and 25.8%, respectively; 64.5% of women were iodine deficient, 46.5% vitamin A deficient, and 20.5% had insufficient folate levels. Women in rural areas had significantly lower iron status and body mass index and higher iodine intake compared with urban areas; 20.9% of children were stunted, 2.8% wasted, 6.2% underweight, 52.4% iron deficient, and 25.8% anaemic; all more prominent in rural areas. Dietary diversity was higher among urban women. Intraindividual or household double burden was not seen. In summary, double burden of malnutrition constituted an increase in overweight among women, especially in urban areas, and persisting levels of undernutrition (stunting, iron, and vitamin A deficiency), predominately in rural areas. A holistic, innovative approach is needed to improve infant and young children feeding and advise mothers to maintain an adequate diet.

Liver is widely eaten by preschool children in the Northern Cape province of South Africa: Implications for routine vitamin A supplementation.

Previous research has demonstrated a virtual absence of vitamin A deficiency and adequacy of vitamin A intake through consumption of liver in preschool children of a community in the Northern Cape province of South Africa where sheep farming is common, and liver, an exceptionally rich source of vitamin A, is frequently eaten. Only 60-75 g of liver per month is needed to meet the vitamin A requirement of preschool children. Because this may have implications for routine vitamin A supplementation, and because liver consumption for the rest of the province is unknown, the study aim was to establish the prevalence and frequency of liver intake in a provincial-wide survey. An unquantified liver-specific food frequency questionnaire, covering a period of 1 month, complemented by a 1-year recall, was administered to mothers of 2- to 5-year-old children (n = 2,864) attending primary health care facilities in all five districts and 26 subdistricts. A total of 86% of children were reported to eat liver, which was eaten in all districts by at least 80% of children. The overall median frequency of liver intake was 1.0 [25th, 75th percentiles: 0.5, 3.0] times per month and ranged from 1.0 [0.3, 2.0] to 2.0 [1.0, 4.0] for the various districts. Based on a previously reported portion size of 66 g, these results suggest vitamin A dietary adequacy in all districts and possibly also vitamin A intake exceeding the Tolerable Upper Intake Level in some children. Routine vitamin A supplementation in this province may not be necessary and should be reconsidered.

Food, water, energy, and macronutrient intake of non-breastfed infants and young children (0-3 years).

PURPOSE: The French Nutri-Bébé 2013 study aimed to assess the nutritional intake of infants and young children in comparison with the recommendations of the 2013 European Food Safety Authority (EFSA). METHODS: This cross-sectional study enrolled a random sample of families selected according to the Quota sampling method. A 3-day dietary record was conducted and supervised by two face-to-face interviews. All foods and beverages consumed were qualitatively and quantitatively reported in a diary, and their composition calculated using a food composition database. RESULTS: A total of 1035 non-breastfed children were included. Formula was abandoned early, amounting to approximately 50% of the total food intake at 7 months in 50% of infants and 22% at 1 year. A similar trend was observed for specific complementary foods. After 1 year, 50% of children consumed cow's milk, which was semi-skimmed in 88% of cases. Drinking water intake was low. Protein intake reached 1.4 times the average requirements before 3 months, 2 times at 8-9 months, and > 4 times at 30-35 months. Fat intake was below the EFSA adequate intake (AI) in > 90% of children. Alpha-linolenic acid intake was equal to or greater than the AI in all infants < 3 months, 85% of children at 6 months, 34% at 12-17 months, and 8% >24 months. Regardless of age, docosahexaenoic acid (DHA) intake was less than the AI. CONCLUSION: Strong discrepancies are observed between the actual and recommended intake in young, non-breastfed children namely, a high-protein intake, and a low fat intake, especially DHA.

Association between dietary selenium intake and the prevalence of osteoporosis: a cross-sectional study.

OBJECTIVE: To examine the correlation between dietary selenium (Se) intake and the prevalence of osteoporosis (OP) in the general middle-aged and older population in China. METHODS: Data for analyses were collected from a population based cross-sectional study performed at the Xiangya Hospital Health Management Centre. Dietary Se intake was evaluated using a validated semi-quantitative food frequency questionnaire. OP was diagnosed on the basis of bone mineral density scans using a compact radiographic absorptiometry system. The correlation between dietary Se intake and the prevalence of OP was primarily examined by multivariable logistic regression. RESULTS: This cross-sectional study included a total of 6267 subjects (mean age: 52.2 ± 7.4 years; 42% women), and the prevalence of OP among the included subjects was 9.6% (2.3% in men and 19.7% in women). Compared with the lowest quartile, the energy intake, age, gender and body mass index (BMI)-adjusted odds ratios of OP were 0.72 (95% confidence interval [CI] 0.55-0.94), 0.72 (95% CI 0.51-1.01) and 0.47 (95% CI 0.31-0.73) for the second, third and fourth quartiles of dietary Se intake, respectively (P for trend = 0.001). The results remained consistent in male and female subjects. Adjustment for additional potential confounders (i.e., smoking status, drinking status, physical activity level, nutritional supplements, diabetes, hypertension, fibre intake, and calcium intake) did not cause substantial changes to the results. CONCLUSIONS: In the middle-aged and older humans, participants with lower levels of dietary Se intake have a higher prevalence of OP in a dose-response manner.

Complementary feeding practices in Mexican healthy infants: How close are they to the current guidelines? / Prácticas de alimentación complementaria en lactantes sanos en México: ¿qué tan apegadas se encuentran al consenso actual?

Abstract Background: The foundations for the growth and optimal development of every human being are laid in the first 2 years of life. Exclusive breastfeeding (EBF) up to 6 months of age and the introduction of complementary feeding (CF) from this age are considered the preventive interventions with the most significant impact on a child's life. The objective of this study was to determine if pediatricians base their recommendations by following the Guidelines for CF in Healthy Infants (GCFHI) and if mothers have any awareness and knowledge of these recommendations. Methods: Surveys based on the GCFHI were conducted in a group of mothers (n = 377) and pediatricians (n = 104) living in Mexico. Results: Not all pediatricians recommended the EBF, and 76% recommended infant formula before 6 months of age. Regarding mothers, 76.9% practiced the EBF for the first 6 months. Vegetables were the leading starting food of CF suggested by pediatricians and mothers (87% and 91%, respectively), contrasting with food sources of iron (44%), which are the foods of choice according to the GCFHI. The practices performed by the mothers were statistically different from the recommendations of the pediatricians. Conclusions: The results reflect a lack of updating regarding CF. It is imperative to reinforce efforts to maintain the EBF for 6 months and to continue it together with the CF, as well as to promote the beginning of CF based on macro- and micro-nutrients.

Resumen Introducción: En los primeros dos años de vida se crean las bases para el crecimiento y desarrollo óptimo de todo ser humano. La lactancia materna exclusiva (LME) hasta los 6 meses de edad y la introducción de alimentación complementaria (AC) a partir de esta edad están consideradas como las intervenciones preventivas de mayor impacto en la vida de un niño. El presente trabajo evalúa en qué medida los pediatras basan sus recomendaciones en el Consenso para las prácticas de alimentación complementaria en lactantes sanos (CALCS) y si las madres están familiarizadas con estas recomendaciones. Métodos: Se realizaron encuestas para madres (n = 377) y pediatras (n = 104) residentes en México basadas en el CALCS. Resultados: Se detectó que no todos los pediatras recomendaron la LME, y el 76% la complementa con sucedáneos de la leche materna antes de los 6 meses. El 76.9% de las madres practicaron la LME por 6 meses. Las verduras fueron el principal alimento de inicio de AC sugerido por pediatras y madres (87% y 91%, respectivamente), lo que contrasta con alimentos fuente de hierro (44%) que según el CALCS son los alimentos de elección. Las prácticas de las madres tuvieron diferencias significativas con las recomendaciones de los pediatras. Conclusiones: Hay una falta de formación y actualización en esta materia. Es imperativo reforzar los esfuerzos para mantener la LME por 6 meses y continuarla junto con la AC, así como promover el inicio de la AC con base en los macro y micronutrientes.

Fortification of bakery and corn masa-based foods in Mexico and dietary intake of folic acid and folate in Mexican national survey data.

BACKGROUND: In Mexico, wheat and corn flour fortification with folic acid (FA) was implemented in 2001 and mandated in 2008, but without direct enforcement. Current Mexican nutrient-content tables do not account for FA contained in bakery bread and corn masa-based foods, which are dietary staples in Mexico. OBJECTIVE: The objective of this study was to examine the impact of FA fortification of dietary staples on the proportion of the population consuming below the Estimated Average Requirement (EAR) for folate or above the Tolerable Upper Intake Level (UL) for FA. METHODS: We measured FA and folate content in dietary staples (bakery bread and tortillas) using microbial assays and MS, and we recalculated FA intake from 24-h recall dietary intake data collected in the 2012 Mexican National Health and Nutrition Survey (Encuesta Nacional de Salud y Nutrición) utilizing estimates from our food measurements, using nutrient concentrations from tortillas to approximate nutrient content of other corn masa-derived foods. The revised FA intake estimates were used to examine population-level intake of FA and dietary folate equivalent (DFE) accounting for geographic differences in FA content with statistical models. RESULTS: FA content in dietary staples was variable, whereas use of FA-fortified flour in corn masa tortillas increased with population size in place of residence. Accounting for dietary staples' FA fortification increased population estimates for FA and DFE intake, resulting in a lower proportion with intake below the EAR and a higher proportion with intake above the UL. Despite accounting for FA-fortified staple foods, 9-33% of women of childbearing age still have intake below the EAR, whereas up to 12% of younger children have intake above the UL. CONCLUSIONS: Unregulated FA fortification of dietary staples leads to unpredictable total folate intake without adequately impacting the intended target. Our findings suggest that monitoring, evaluation, and enforcement of mandatory fortification policies are needed. Without these, alternate strategies may be needed in order to reach women of childbearing age while avoiding overexposing children.

Increased coffee, tea, or other sugar-sweetened beverage consumption in adolescents is associated with less satisfactory dietary quality, body fatness and serum uric acid profiles over the past 18 years in Taiwan.

BACKGROUND AND OBJECTIVES: Taiwan has a high density of convenience stores and beverage shops, which makes sugar-sweetened beverages (SSBs) very accessible to teenagers. This study examined the changes and the association between SSBs and biomarkers and nutrient intake, for teenagers over the course of 18 years using a national representative sample. METHODS AND STUDY DESIGN: This cross-sectional study used data from the Nutrition and Health Survey in Taiwan (NAHSIT). Complete data for teenagers aged 13 to 19 years including a 24-hour dietary recall, anthropometric and clinical measurements, and SSBs from two periods were analyzed (1993-1996: N=1820; 2010-2011: N=2513). SAS callable SUDAAN was used for statistical analysis, adjusting for the sampling scheme. Log transformation was used for non-normal variables before linear models were used. Coffee or tea and SSB (excluding tea or coffee) consumers were categorized as non-drinkers, low (below), or high (above) consumers based on median intake during 1993-1996. RESULTS: Intake of coffee or tea increased significantly in the 18 years of this study (p<0.01), whereas intake of SSBs (excluding coffee or tea) decreased significantly (p<0.05). Intake was significantly higher among second survey and those with high total energy intakes (p<0.01). For both coffee/tea and SSB, the high-intake groups had higher serum uric acid and intake of carbohydrates (p<0.05), lower intake of protein and phosphorus and lower dietary diversity score (p<0.05). CONCLUSIONS: Consumption of coffee or tea increased in adolescents during the 18 years. High intakes of SSB, coffee or tea was associated with high serum uric acid values and worse dietary quality.

Effects of a dietary supplement on inflammatory marker expression in middle-aged and elderly hypertensive patients.

OBJECTIVES: We aimed to explore the effects of diet on the inflammatory response in middle-aged and elderly people with hypertension. METHODS: Thirty overweight or obese patients with stage one hypertension (age range, 45-75 years) were allocated to either the intervention or control group (n=15 per group; age- and sex-matched). Patients in the intervention group consumed a food powder supplement (100 g) instead of a regular meal. The control group maintained their normal dietary habits. This study lasted for six weeks. Blood pressure, inflammatory marker levels, and energy intake were measured before and after the study. RESULTS: After 6 weeks, the diet composition of the intervention group changed significantly (p<0.05). The intake of proteins, dietary fibre, monounsaturated fat, and polyunsaturated fat increased significantly (p<0.05), while the total energy intake trended towards an increase (p>0.05). In the control group, the total energy intake decreased significantly (p<0.05). The levels of nuclear factor-κB (NF-κB), soluble intercellular adhesion molecule-1 (sICAM-1) and high sensitivity C-reactive protein (hs-CRP) decreased, and adiponectin increased significantly in the intervention group (p<0.05); however, no significant changes were observed in the inflammatory marker levels of the control group. In the intervention group, systolic blood pressure decreased significantly (p<0.05), and diastolic blood pressure also exhibited a decreasing trend. No significant change in blood pressure was observed in the control group. CONCLUSION: The consumption of a food powder supplement can improve diet composition, decrease blood pressure and reduce inflammation in middle-aged and elderly overweight or obese hypertensive patients. The food powder supplement may also have an anti-atherosclerotic effect in hypertensive patients.

Use of dietary supplements in relation to urinary phthalate metabolite concentrations: Results from the National Health and Nutrition Examination Survey.

BACKGROUND: Research suggests that dietary supplements may be a source of exposure to phthalates, given that diethyl phthalate (DEP) or di-n-butyl phthalate (DBP) can be components of coatings that facilitate extended release or encapsulate dietary supplements. METHODS: Using nationally representative data on a population of 12,281 adults ages 20 y + surveyed between 1999 and 2014 from the National Health and Nutrition Examination Survey (NHANES), we evaluated the association between dietary supplement use in relation to urinary phthalate metabolites of DEP (monoethyl phthalate, MEP) and DBP (mono-n-butyl phthalate, MBP). We examined associations pertaining to regular use of multivitamin/multimineral (MVMM) supplements, as well as regular use of any other non-MVMM supplement products, the number of non-MVMM supplement products used, as well as individual supplements potentially containing phthalates (exclusive of MVMM). For each urinary phthalate metabolite, results are presented as the minimally-adjusted and multivariable-adjusted ratio, comparing the geometric mean among users to non-users. RESULTS: In multivariable models, we observed a significant positive association between regular use of MVMM use and MEP, with persons using MVMM supplements having 11% higher geometric mean MEP than non-users (Ratio: 1.11; 95% CI: 1.04-1.20); no association was observed for MVMM in relation to MBP. No other significant multivariable-adjusted associations were observed, although power was limited in analyses of individual supplements. Associations did not markedly vary by gender; however, the associations of garlic supplement use with MEP and MBP varied by calendar time, with statistically significant positive associations observed in later years. CONCLUSIONS: A modest significant association was observed between MVMM use and MEP. No other significant associations were observed in our overall multivariable models. Follow-up on the positive association observed between garlic and urinary phthalate metabolite concentrations observed in later years in a well-powered, prospective study would further clarify study findings.

Is selenium intake associated with the presence of depressive symptoms among US adults? Findings from National Health and Nutrition Examination Survey (NHANES) 2011-2014.

OBJECTIVES: This study aimed to examine the cross-sectional association between dietary and serum selenium measures and depressive symptoms among a nationally representative sample of US adults. METHODS: Dietary selenium intake and serum selenium concentration were evaluated on 7725 adult participants from National Health and Nutrition Examination Survey (NHANES) 2011-2014. Participants' selenium intake, assessed by 24-h recall, was classified based on the recommended dietary allowance (dietary selenium intake ≥ 55 µg/d) and estimated average requirement (dietary selenium intake ≥ 45 µg/d) criteria. Serum selenium and depressive symptoms were assessed using inductively coupled plasma mass spectrometry and a patient health questionnaire or use of an antidepressant, respectively. Univariate and multivariate logistic regression, accounting for the complex survey design of NHANES, were employed to estimate the cross-sectional association between measures of selenium and the presence of depressive symptoms. RESULTS: The median selenium concentration was 193.9 µg/L (interquartile range = 179.3-209.3). Approximately 8% of the participants met the case definition for depressive symptoms. Based on the recommended dietary allowance of selenium, participants not meeting the recommended dietary intake, compared with those meeting the requirement, had higher odds of depressive symptoms (odds ratio [OR] = 1.57, 95% confidence interval [CI]: 1.03-2.38). When analyzing by quintile of dietary selenium intakes, compared with the first quintile, participants in higher quintiles had significantly lower odds of depressive symptoms. However, based on quintiles of serum selenium and using the first quintile as referent category, except for quintile 3, results indicated a higher but not significant association (quintile 2 [OR = 1.08, 95% CI: 0.73-1.61], quintile 4 [OR = 1.17, 95% CI: 0.89-1.55], and quintile 5 [OR = 1.14, 95% CI: 0.83-1.58]). Power analysis indicated sufficient power. Notably, study participants had a very high serum selenium concentration. The findings, although not significant, between serum selenium concentrations and depressive symptoms had a U-shaped association, supported by the current literature. CONCLUSIONS: Our study supports an inverse association between participants recommended dietary intake of selenium and depressive symptoms. Although results were not statistically significant for the association by quartile of serum selenium concentrations and depressive symptoms, a U-shaped association was identified.

Adequacy of macro and micronutrients in infants and young children's diets in Zanzibar, Tanzania.

BACKGROUND: A study was conducted in Zanzibar using ProPAN software to assess nutrient adequacy of foods given to infants and children aged 6-23 months old in Zanzibar. METHODOLOGY: The 24-hr dietary recall method embedded in ProPAN software was used to determine the adequacy of energy, protein, iron, calcium, zinc and vitamin A in foods consumed by children. Sample of 200 mothers/caretakers with children aged 6-23 months were interviewed. RESULTS: Most frequent foods given to infants and children were tea, bread, white rice and fish. Key nutrients such as iron, zinc and vitamin A were below the recommended levels except for vitamin C from the diets consumed by children aged 11-23 months. Energy and protein were considered to be adequate as more than 90% of the children received enough of these nutrients. Mean age of introduction of complementary foods was four months. CONCLUSION: Children diets were limited in fruits and vegetables that caused micronutrients of nutritional importance such as iron, zinc and vitamin A to be supplied below recommended level. Equally, fat intake was below recommended level. Nutrition education on appropriate complementary foods should be given to caregivers. Promotion of consumption of diversified diets and locally available nutrient dense foods should be emphasized so as to achieve adequate intake of nutrients to infants and young children.
