The aim of this study was to assess the association between daily diet costs and the Healthy Eating Food Index (HEFI)-2019, an index that reflects the alignment of dietary patterns to recommendations on healthy food choices in the 2019 Canada’s Food Guide (CFG). Dietary intake data from 24 h recalls, completed between 2015 and 2017, of 1147 French-speaking participants of the web-based multicenter cross-sectional PRÉDicteurs Individuels, Sociaux et Environnementaux (PREDISE) study in Quebec were used. Diet costs were calculated from dietary recall data using a Quebec-specific 2015–2016 Nielsen food price database. Usual dietary intakes and diet costs were estimated using the National Cancer Institute’s multivariate method. Linear regression models were used to evaluate associations between diet costs and HEFI-2019 scores. When standardized for energy intake, a higher HEFI-2019 score (75th vs. 25th percentiles) was associated with a 1.09 $CAD higher daily diet cost (95% CI, 0.73 to 1.45). This positive association was consistent among different sociodemographic subgroups based on sex, age, education, household income, and administrative region of residence. A higher daily diet cost was associated with a higher HEFI-2019 score for the Vegetables and fruits, Beverage, Grain foods ratio, Fatty acids ratio, Saturated fats, and Free sugars components, but with a lower score for the Sodium component. These results suggest that for a given amount of calories, a greater adherence to the 2019 CFG recommendations on healthy food choices is associated with an increased daily diet cost. This highlights the challenge of conciliating affordability and healthfulness when developing national dietary guidelines in the context of diet sustainability.  相似文献

We intended to precisely evaluate the dietary quality of male and female medical college students using canteen data from the “Intelligent Ordering System” (IOS), combined with the supplemental food frequency questionnaire (SFFQ) and the Chinese Healthy Eating Index (CHEI) in Shanghai, China, to explore the potential factors influencing dietary quality. A total of 283 college students with the average age of 24.67 ± 3.21 years and Body Mass Index of 21.46 ± 3.49 kg/m2 in the medical school were enrolled in this study, and an online questionnaire investigation was conducted to collect the general information, lifestyle behavior, and SFFQ. The dietary data of the study participants from the school canteen were exported from the IOS of the Information Office of Fudan University. The CHEI consists of 17 components and the total score is 100, with a maximum score of each component of 5 or 10. We calculated each component score of the CHEI and aggregated the total score for male and female study participants. The Chi-square test and Wilcoxon rank sum test were employed in comparing the differences between the demographic characteristics and CHEI component scores of males and females. Univariate and multiple linear regression models were employed to examine the potential influencing factors of the total CHEI score. The CHEI median score was 66.65, and the component score for total grains was relatively low. Added sugars was the most overconsumed CHEI component. There were relatively serious deficiencies, based on the CHEI component scores, in fruits, soybeans, fish and seafood, and seeds and nuts in both sexes. Females had significantly higher CHEI scores than males (68.38 versus 64.31). The scores for tubers, total vegetables, dark vegetables, fruits, fish and seafood, dairy, and red meats were significantly higher in females than in males. Influencing factors including sex, education, dietary health literacy, and amount of time spent sedentarily were significantly associated with CHEI score. Our research revealed that the overall dietary quality needs to be further improved for college students at the medical school in Shanghai, China, with low intakes of total grains, fruits, soybeans, fish and seafood, and seeds and nuts, and high intakes of added sugars. Compared with males, females showed higher diet quality and conformed more strongly with the recommended Dietary Guideline for Chinese. Education, dietary health literacy, and amount of time spent sedentarily should be noted for improving the dietary quality of college students.  相似文献

Diet has been identified as a risk factor for some cancers, but its role in adult de novo acute myeloid leukemia (AML) is unclear. This study was conducted at the University of Texas MD Anderson Cancer Center to evaluate associations between consumption of vegetables, fruits, and meats with AML risk among Texas residents. All participants, 323 adult de novo AML cases and 380 frequency-matched controls, completed demographic and food frequency questionnaires. Overall, AML risk was significantly decreased among those who consumed the most dark green vegetables, seafood, and nuts/seeds; and it was significantly increased among greatest consumers of red meat. Among men, AML risk was lowest among those whose consumption was in the highest quartile for fruits [odds ratio (OR) = 0.25, 95% confidence interval (CI) = 0.10–0.69], poultry (OR = 0.28, 95%CI = 0.10–0.78), and seafood (OR = 0.39, 95%CI = 0.16–0.96) compared to those in the lowest. Among women, risk was lowest among those whose consumption was in the highest quartile of dark-green vegetables (OR = 0.28, 95%CI = 0.12–.68), orange vegetables (OR = 0.40, 95%CI = 0.17–.96) and nuts/beans (OR = 0.26, 95%CI = 0.11–0.60). Based on these findings, interventions can be developed to modify intake of specific dietary components to reduce cancer risk.  相似文献

BackgroundEvaluating diet quality is a way to monitor a population’s adherence to dietary guidelines.ObjectiveTo adapt the Healthy Eating Index-2015 (HEI-2015) to the Brazilian population, to evaluate the validity and reliability of the adapted HEI-2015, and to assess diet quality of Brazilian adults as well as socioeconomic and demographic factors associated with diet quality.DesignIn this cross-sectional study, two dietary records from nonconsecutive days were used to obtain food intake information. The collected socioeconomic and demographic data included sex, age, education, per capita income, and residence area.Participants/settingA representative sample (n=27,760) of the Brazilian adult population participated in the Nutrition Dietary Survey 2008-2009.Main outcome measuresTotal and component scores for the adapted HEI-2015. The validity and reliability of the index were tested.Statistical analysis performedMean total and component scores were estimated for the adapted HEI-2015. Also, the proportion of subjects that achieved the maximum score for each component was calculated. Regarding validity and reliability analysis, principal components analysis examined the number of dimensions; Pearson correlations were estimated between total score, components, and energy, and Cronbach’s coefficient α was estimated. Diet quality was compared among socioeconomic and demographic categories.ResultsThe mean total score for the adapted HEI-2015 was 45.7 (95% CI: 45.4 to 46.0). Women had higher diet quality scores (46.4; 95% CI: 46.1 to 46.7) than men (44.9; 95% CI: 44.6 to 45.3). Age, education, and per capita income were directly associated with the adapted HEI-2015 total score. Greater than or equal to 50% of subjects received the maximum adapted HEI-2015 component scores for “total protein foods,” “seafood and plant proteins,” “fatty acids,” and “sodium.” In contrast, less than 30% of subjects received the maximum component scores for “total vegetables,” “dairy,” and “saturated fats.” Higher percentages of women received the maximum component scores for “total fruits,” “whole fruits,” “total vegetables,” “greens,” “dairy,” and “sodium,” whereas higher percentages of men received the maximum component scores for “total protein foods,” “seafood and plant proteins,” “fatty acids,” “added sugars,” and “saturated fats” components. Finally, validity analysis revealed weak correlations between component scores and energy and weak to moderate correlations with total scores; six dimensions were responsible for the total variance in diet quality and the standardized Cronbach’s coefficient α was .65 (unstandardized=.64).ConclusionsBrazilian adults have suboptimal diet quality as assessed by the adapted HEI-2015. Diet quality varied by socioeconomic and demographic factors. Results support the validity and the reliability of the index.  相似文献

OBJECTIVE: To predict the mean adequacy ratio (MAR) scores of mothers and toddlers from intakes of fruits, vegetables, and dairy group foods and being seated during mealtimes. DESIGN/SUBJECTS: This was a regression analysis of cross-sectional data of the diet quality and being seated during mealtimes of 100 rural mother-toddler dyads from limited-income families using two 24-hour dietary recalls. Children were 11 to 25 months of age and at or below 100% of the poverty index. MEASURES OF OUTCOME: Dietary quality for mothers and toddlers was assessed using a MAR score for eight different nutrients (vitamin A, vitamin C, vitamin D, folate, calcium, zinc, iron, and magnesium), and a score of 85 or above was considered nutritionally adequate. The main food groups of interest were servings from the fruits, vegetables, and dairy group foods. Mealtime sitting behavior was the percentage of times the toddler remained seated while eating. RESULTS: Servings of fruits, vegetables, and dairy foods predicted 0.62 of the variance in the mother's MAR score, whereas vegetable and dairy intakes along with being seated while eating indicated nutritional adequacy for toddlers. Mothers with low MAR scores were most likely to have toddlers with poor diets, although few toddlers had poor diet quality. CONCLUSIONS: Adequate intakes of dairy, vegetables, and whole fruits along with being seated while eating could be quick assessment tools to screen toddlers for nutritional risk. Mothers with poor diet quality were likely to have toddlers with poor diets; low intakes of fruits, vegetables, and dairy foods were markers for poor diet quality in mothers.  相似文献
