Abstract Background The association between daily dietary folate intake and cognitive performance in older populations is unclear. Methods This study aimed to investigate whether a dose-dependent association exists between dietary folate levels and cognition performance. The 2011–2014 datasets from the National Health and Nutrition Examination Survey were collected. Data from adults aged ≥ 60 years who completed all three cognitive tests with daily dietary data were analyzed. Weighted smooth curve fitting and multiple linear regression models were applied to study the association between folate intake and cognitive performance. Age, sex, race, education, smoking status, alcohol intake, body mass index, hypertension, stroke, diabetes, and depression were adjusted using a weighted multiple regression model. Results Data from 1,255 participants were analyzed. The mean age of the study population was 69.3 years. Males accounted for a weighted 48.8% of the total population. Daily dietary folate was not significantly associated with delayed recall (per 10 mcg/day increment, β 0.003, 95% CI -0.002–0.009, P = 0.23). Below the cut-off of 250 mcg/day, dietary folate intake was positively associated with immediate recall (per 10 mcg/day increment, β 0.01, 95% CI 0.00–0.02, P = 0.05) and animal fluency test score (per 10 mcg/day increment, β 0.02, 95% CI 0.00–0.03, P = 0.05). However, above this cut-off, the association was not significant. Dietary folate intake was not significantly associated with an increase in the digit symbol substitution test score until dietary the folate intake reached 250 mcg/d (per 10mcg/d increment, β 0.29, 95% CI 0.05-0.53, P = 0.04). Conclusion Daily dietary folate intake was non-linearly associated with cognitive performance in the older American population.

Prospective Investigation

Folate plays an important role in the synthesis and methylation of DNA as a cofactor in one-carbon metabolism. Inadequate folate intake has been linked to adverse health events. However, comparable information on dietary folate intake across European countries has never been reported. The objective of the present study was to describe the dietary folate intake and its food sources in ten countries in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. A cross-sectional analysis was conducted in 36 034 participants (aged 35–74 years) who completed a single 24 h dietary recall using a computerised interview software program, EPIC-Soft® (International Agency for Research on Cancer, Lyon). Dietary folate intake was estimated using the standardised EPIC Nutrient DataBase, adjusted for age, energy intake, weight and height and weighted by season and day of recall. Adjusted mean dietary folate intake in most centres ranged from 250 to 350 μg/d in men and 200 to 300 μg/d in women. Folate intake tended to be lower among current smokers and heavier alcohol drinkers and to increase with educational level, especially in women. Supplement users (any types) were likely to report higher dietary folate intake in most centres. Vegetables, cereals and fruits, nuts and seeds were the main contributors to folate intake. Nonetheless, the type and pattern of consumption of these main food items varied across the centres. These first comparisons of standardised dietary folate intakes across different European populations show moderate regional differences (except the UK health conscious group), and variation by sex, educational level, smoking and alcohol-drinking status, and supplement use.

Abstract There are few studies examining the association between homocysteine (Hcy) level and the risk of hypertension with consideration for folate and vitamin B12 as related to Hcy level. We simultaneously examined the associations of plasma levels of Hcy, folate, and vitamin B12, and dietary folate intake with the prevalence of hypertension. Participants included 1046 men and 1033 women (mean age ± standard deviation: 56.0 ± 8.9 years) in the Japan Multi-Institutional Collaborative Cohort Study. Dietary folate intake was estimated using a validated food frequency questionnaire. Hypertension was defined based on measured blood pressure and use of antihypertensive medication. A total of 734 participants (35.3%) had hypertension. Multivariate-adjusted odds ratios of hypertension for the highest quartile group of Hcy were 2.36 (95% CI 1.41–3.96) in men and 1.86 (95% CI 1.11–3.11) in women, as compared with the lowest group (P for trend = 0.014 and 0.005, respectively). Dietary folate intake was not correlated with hypertension in both men and women (P for trend = 0.099 and 0.703, respectively). Plasma vitamin B12 was positively associated with hypertension only in women (P for trend = 0.027). Plasma Hcy level was positively linked with hypertension after controlling for covariates, including folate and vitamin B12.

Dietary Folate Intake

Folate, vitamin B6, and vitamin B12 intake can be important regulators for obesity development. Thus, we investigated the possible association between the intake of these vitamins and the excess body weight or obesity prevalence in the participants of the Cohort of Universities in Minas Gerais (CUME project). This study analyzed cross-sectional data of 2695 graduates and postgraduates from universities in the state of Minas Gerais (801 men, 1894 women, ages 36.2 ± 9.4). The first step consisted of collecting data online, and the second step consisted of blood collecting in the subsample living in the city of Viçosa and its region (Minas Gerais). Excess body weight and obesity prevalence were 38.1% and 10.1%, respectively. Inadequate intake of folate, B6, and B12 were 12, 6.3, and 11.1%, respectively. Beans/lentils and French bread presented the highest contribution to folate intake (23.45% and 10.01%, respectively). Those individuals in the third tertile for folate intake (≥511.12 μg/d) had a lower excess body weight [prevalence ratio (PR): 0.79, confidence interval (CI): 0.71–0.8] and obesity prevalence (PR: 0.60, CI: 0.45–0.78). These associations were maintained when the sample was categorized by sex. In addition, serum folate was positively associated with dietary folate (p for trend = 0.032) and negatively associated with serum homocysteine (p for trend = 0.003) in the subsample. Dietary folate intake was negatively associated with excess body weight and obesity in CUME participants, indicating the relevance of this vitamin dietary assessment.

The aim of this study was to assess the adequacy of dietary folate intake and perceptions of pill burden among Saudi patients on maintenance hemodialysis (MHD). This was a cross-sectional study of adults (>18 years) on MHD (>3 months) attending the dialysis unit at King Saud University Medical City. Patient demographics, dietary folic acid intake, and perceptions of pill burden were collected. Fifty-four patients met the eligibility criteria, with a mean age of 57 ± 15.5 years. The majority were females (63%), and the most prevalent comorbidities were diabetes (43%) and hypertension (76%). The average number of medications/patients was 11 ± 2.9, and most patients were receiving folate supplementation (68.5%). The average dietary folate intake was 823 ± 530 mcg/day. Pill burden was bothersome, primarily due to taking too many medications (57%) while taking medications at the workplace was the least bothersome burden (17%). The reported high pill burden and adequate dietary folate intake by Saudi patients on MHD indicates that the omission of folate supplementation may be advantageous for this special population.

Psoriasis Severity

Background: Folic acid fortification program has been established to prevent tube defects. However, concern has been raised among patients using anti-folate drug, i.e. psoriatic patients, a common, chronic, autoimmune inflammatory skin disease associated with obesity and smoking. Objective: To investigate dietary and circulating folate, vitamin B12 (B12) and homocysteine (hcy) in psoriatic subjects exposed to the national mandatory folic acid fortification program. Methods: Cross-sectional study using the Food Frequency Questionnaire, plasma folate, B12, hcy and psoriasis severity using the Psoriasis Area and Severity Index score. Median, interquartile ranges (IQRs) and linear regression models were conducted to investigate factors associated with plasma folate, B12 and hcy. Results: 82 (73%) mild psoriasis, 18 (16%) moderate and 12 (11%) severe psoriasis. 58% female, 61% non-white, 31% former smokers, and 20% current smokers. Median (IQRs) were 51 (40, 60) years. Only 32% reached the Estimated Average Requirement of folate intake. Folate and B12 deficiencies were observed in 9% and 6% of the blood sample respectively, but hyperhomocysteinaemia in 21%. Severity of psoriasis was negatively correlated with folate and B12 concentrations. In a multiple linear regression model, folate intake contributed positively to 14% of serum folate, and negative predictors were psoriasis severity, smoking habits and saturated fatty acid explaining 29% of circulating folate. Conclusion: Only one third reached dietary intake of folate, but deficiencies of folate and B12 were low. Psoriasis severity was negatively correlated with circulating folate and B12. Stopping smoking and a folate rich diet may be important targets for managing psoriasis.

BACKGROUND: Low Health Literacy (HL) and Nutrition Literacy (NL) are associated with serious negative health outcomes. OBJECTIVES: The aim of this study was to investigate certain lifestyle factors and obesity, in relation to HL and NL. METHODS: This cross-sectional study was conducted in the urban area of the Attica region, in Greece. The sample consisted of 1281 individuals, aged ≥18 years. HL, NL sociodemographic characteristics and lifestyle factors (physical activity, smoking status, alcohol consumption,) were assessed. Mann-Whitney U, the Kruskall Wallis, Pearson chi-square tests and multiple linear regression models were used. RESULTS: Linear regression analysis has shown that smoking, alcohol consumption and physical activity, were associated with HL levels (–1.573 points for ex-smokers in comparison to smokers, p = 0.035, –1.349 points for alcohol consumers in comparison to non-consumers, p = 0.006 and 1.544 points for physically active individuals to non-active, p = 0.001). With respect to NL levels, it was also not associated with any of these factors. Obesity was not associated with HL and NL levels. CONCLUSIONS: Certain lifestyle factors, including physical activity, are predicting factors of HL levels, in Greek adults. The results contribute to the understanding of the relationship between lifestyle factors and HL and should be taken into account when HL policies are designed.

AbstractObjectiveFolic acid food fortification has successfully reduced neural tube defect-affected pregnancies across Canada. The effect of this uncontrolled public health intervention on folate intake among Canadian children is, however, unknown. Our objectives were to determine folic acid intake from food fortification and whether fortification promoted adequate folate intakes, and to describe folic acid-fortified food usage among Ontario preschoolers.DesignCross-sectional data were used from the NutriSTEP™ validation project with preschoolers recruited using convenience sampling. Mean daily total folate and folic acid intakes were estimated from 3 d food records, which included multivitamin supplement use. Comparisons were made to Dietary Reference Intakes, accounting for and excluding fortificant folic acid, to determine the prevalence of inadequate and excessive intakes.SettingCanada.SubjectsTwo hundred and fifty-four preschoolers (aged 3–5 years).ResultsAll participants (130 girls, 124 boys) ate folic acid-fortified foods and 30 % (n76) used folic acid-containing supplements. Mean (se) fortificant folic acid intake was 83 (2) μg/d, which contributed 30 % and 50 % to total folate intake for supplement users and non-users, respectively. The prevalence of total folate intakes below the Estimated Average Requirement was <1 %; however, excluding fortificant folic acid, the prevalence was 32 %, 54 % and 47 % for 3-, 4- and 5-year-olds, respectively. The overall prevalence of folic acid (fortificant and supplemental) intakes above the Tolerable Upper Intake Level was 2 % (7 % among supplement users).ConclusionsFolic acid food fortification promotes dietary folate adequacy and did not appear to result in excessive folic acid intake unless folic acid-containing supplements were consumed.
