Background Dietary vitamin K (K 1 and K 2 ) may reduce atherosclerotic cardiovascular disease (ASCVD) risk via several mechanisms. However, studies linking vitamin K intake with incident ASCVD are limited. We aimed to determine the relationship between dietary vitamin K intake and ASCVD hospitalizations. Methods and Results In this prospective cohort study, participants from the Danish Diet, Cancer, and Health Study, with no prior ASCVD, completed a food‐frequency questionnaire at baseline and were followed up for hospital admissions of ASCVD; ischemic heart disease, ischemic stroke, or peripheral artery disease. Intakes of vitamin K 1 and vitamin K 2 were estimated from the food‐frequency questionnaire, and their relationship with ASCVD hospitalizations was determined using Cox proportional hazards models. Among 53 372 Danish citizens with a median (interquartile range) age of 56 (52–60) years, 8726 individuals were hospitalized for any ASCVD during 21 (17–22) years of follow‐up. Compared with participants with the lowest vitamin K 1 intakes, participants with the highest intakes had a 21% lower risk of an ASCVD‐related hospitalization (hazard ratio, 0.79; 95% CI: 0.74–0.84), after multivariable adjustments for relevant demographic covariates. Likewise for vitamin K 2 , the risk of an ASCVD‐related hospitalization for participants with the highest intakes was 14% lower than participants with the lowest vitamin K 2 intake (hazard ratio, 0.86; 95% CI, 0.81–0.91). Conclusions Risk of ASCVD was inversely associated with diets high in vitamin K 1 or K 2 . The similar inverse associations with both vitamin K 1 and K 2 , despite very different dietary sources, highlight the potential importance of vitamin K for ASCVD prevention.

Purpose: The aim was to validate a food frequency questionnaire (FFQ) against a 3-day food record (3DFR) for pregnant women with a focus on nutrients important for bone health from food and supplements. Methods: The FFQ and 3DFR were administered to pregnant women (n = 42) aged 18–45 years in their third trimester of pregnancy in Hamilton, Ontario. Nutrient analysis of intakes was conducted using an FFQ calculator and Nutritionist-Pro software. The average daily serving consumption of Milk and alternatives group and Vegetable subgroup from Canada’s Food Guide were also compared. Results: There was a high positive correlation between methods for total dietary vitamin D (r = 0.83). Low positive associations were observed for total protein (r = 0.37), calcium (r = 0.36), vitamin K (r = 0.41), and servings of Milk and alternatives (r = 0.36). A cross-classification analysis using participants’ intake quartiles revealed no major misclassifications. Bland–Altman analysis showed that the FFQ mildly underestimated the intake for protein, whereas it grossly overestimated the intake of vitamin K, and daily servings of Milk and alternatives and Vegetable. Conclusions: This FFQ can serve as a useful tool in clinical and research settings to assess key bone nutrients from foods and supplement sources in pregnant women.

Abstract Background: Repeated 24-hour recalls and diet diaries are the most dietary methods, which have been used as gold standards in food frequency questionnaire (FFQ ) validation studies. But associated random errors between the FFQ and these two dietary assessment methods can result in flawed estimates of validity. Therefore, evaluation biochemical indices have been considered as a reference method in validation studies.Objective: The aim of this study was to evaluate the validity of the FFQ by comparing the estimated intakes of folate and vitamin B12 with corresponding biochemical markers. Methods: Participants were 95 healthy adults from Azar Cohort Study. We compared folate and vitamin B12 intakes of food frequency questionnaire with their concentrations in blood specimens. Serum folate and vitamin B12, and of red blood cell folate concentrations, were determined using electrochemiluminescence immunoassay method respectively. Results: Spearman correlation coefficients between dietary folate and corresponding biomarkers (serum and RBC folate) concentrations were 0.04 (P-value = 0.65), 0.06 ( P-value = 0.52) respectively. There was no correlation between dietary vitamin B12 and serum concentrations of this vitamin, whether in crude or energy-adjusted model in the total population studied(r = - 0.134 , p = 0.19 in crude model and r = -0.137, p = 0.18 in energy-adjusted model ). According to the findings of this study, 64.51, 60.21 and 54.83 percent of studied population were in the same/adjacent quartiles of dietary folate-serum folate, dietary folate-red blood cell folate and dietary vitamin B12-serum vitamin B12 respectively.Conclusion: According to our results, it seems that this FFQ may not be a reliable tool to assess intakes of folate and vitamin B12. Therefore, further studies with large sample size are needed to achieve more clear results.

Abstract Objective The aim of the present study was to develop and validate a vitamin D food frequency questionnaire (FFQ) for assessment of dietary vitamin D intake in healthy adults in England, UK. Design: The current study assessed the agreement between a four-day food diary (4d-FD) and a new vitamin D FFQ to measure dietary intake of vitamin D. Dietary intake was estimated using Nutritics dietary analysis software and Spearman’s and Bland-Altman tests were utilised to assess correlation and agreement, respectively. Participants also provided a blood sample for plasma analysis of vitamin D concentrations. Setting: Home setting. Participants: Fifty participants were recruited to the study from the University of Chester and vicinity. Results: Results showed a strong correlation between vitamin D intake recorded by the FFQ and the 4d-FD (r = 0.609; P < 0.0001) within 95% limits of agreement. Furthermore, a significant correlation between plasma 25(OH)D concentrations and vitamin D intake measured by the FFQ (r = 0.290, P = 0.041) and the 4d-FD (r = 0.360, P = 0.01) was observed. Conclusion: Our analysis suggests this FFQ is a useful and rapid tool for researchers and health professionals to assess vitamin D dietary intakes in healthy adults in the UK.
