Griebler R, Schütze D, Link T, Schindler K. Brief instruments for measuring nutrition literacy - the Nutrition Health Literacy Scale and the Self-Perceived Food Literacy Scale Short Form. Nutr J 2024; 23:73. [PMID: 38992716 PMCID: PMC11238471 DOI: 10.1186/s12937-024-00971-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 06/26/2024] [Indexed: 07/13/2024] Open
Abstract
BACKGROUND A healthy diet is a critical factor in maintaining long-term health. In addition to a health-promoting food environment, the nutrition health literacy (NHL) and food literacy (FL) of the population are important in this context. This paper describes the development and validation of two short instruments to measure the nutrition literacy of the population, used in the Austrian Nutrition Literacy Survey 2021. METHODS An instrument to measure NHL (Nutrition Health Literacy Scale; NHLS) has been adapted and further developed. To measure FL, the Self-perceived Food Literacy Scale by Poelman et al. has been modified and shortened (SPFL-SF). Validation of the instruments was based on data from a web survey conducted in Austria in 2021 with almost 3,000 participants aged 18 years and older. Exploratory and confirmatory factor analyses were performed to assess the factorial validity/dimensionality of the instruments. Additionally, internal consistency was assessed using Cronbach's alpha, ordinal alpha, and McDonald's omega. RESULTS Both instruments demonstrate excellent data-model fit. The NHLS also shows excellent internal consistency (α = 0.91), while the SPFL-SF displays a sufficient internal consistency for all (α between 0.70 and 0.89) but one sub-dimension (resisting temptation α = 0.61). Furthermore, the distribution of the items indicates that the measures are understandable and suitable, as evidenced by the absence of missing values in the sample. In addition, the items of both instruments differ in their level of difficulty or agreement. CONCLUSIONS The NHLS and SPFL-SF are reliable and valid instruments for measuring NHL and FL in the general adult population. The brief instruments measuring the different aspects of nutrition literacy can be easily used in nutritional or evaluation studies. Further work is required to investigate other aspects of validity.

[PMID: 38749098 DOI: 10.1016/j.trre.2024.100859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 05/09/2024] [Accepted: 05/10/2024] [Indexed: 06/16/2024]
Abstract
Kidney transplantation (KT) is the best treatment option for end-stage kidney disease (ESKD). Acute rejection rates have decreased drastically in recent years but chronic kidney allograft disease (CKAD) is still an important cause of allograft failure and return to dialysis. Thus, there is unmet need to identify and reverse the cause of CKAD. Additionally, cardiovascular events after KT are still leading causes of morbidity and mortality. One overlooked potential contributor to CKAD and adverse cardiovascular events is increased sodium/salt intake in kidney transplant recipients (KTRs). In general population, the adverse effects of high sodium intake are well known but in KTRs, there is a paucity of evidence despite decades of experience with KT. Limited research showed that sodium intake is high in most KTRs. Moreover, excess sodium intake is associated with elevated blood pressure and albuminuria in some studies involving KTRs. There is also experimental evidence suggesting that increased sodium intake is associated with histologic graft damage. Critical knowledge gaps still remain, including the exact amount of sodium restriction needed in KTRs to optimize outcomes and allograft survival. Additionally, best methods to measure sodium intake and practices to follow-up are not clarified in KTRs. To meet these deficits, prospective long term studies are warranted in KTRs. Moreover, preventive measures must be determined and implemented both at individual and societal levels to achieve sodium restriction in KTRs.

Jiao W. Older Adults' Exposure to Food Media Induced Unhealthy Eating during the COVID-19 Omicron Lockdown? Exploring Negative Emotions and Associated Literacy and Efficacy on Shanghainese. Foods 2024; 13:1797. [PMID: 38928739 PMCID: PMC11203190 DOI: 10.3390/foods13121797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 06/03/2024] [Accepted: 06/05/2024] [Indexed: 06/28/2024] Open
Abstract
The COVID-19 pandemic, propelled by the highly transmissible Omicron variant, had a global impact and significantly affected Shanghai, a major city in China. This study investigates how food media exposure influenced unhealthy eating habits among older adults during the COVID-19 lockdown in Shanghai, focusing on the roles of negative emotions, food literacy, health consciousness, and eating self-efficacy. The random sample comprised 400 individuals aged ≥50 years who lived in Shanghai from March to June 2022. A path and correlation analysis was performed. The exposure of older adults to food media resulted in the acceleration of unhealthy eating. The relationship was significantly exacerbated by food literacy and negative emotions. In contrast, eating self-efficacy and health consciousness effectively countered the media. The enhanced pathway from food-related media influence to eating habits through negative emotions or self-efficacy towards health awareness and food literacy showed significant effects. The findings provide insights for future research and public health strategies. Importantly, this study has practical significance for media professionals, public health decision-makers, and healthy food businesses regarding how to enhance older adults' cognition to respond to unhealthy eating crises.

Abstract
PURPOSE The purpose of the study was to develop and validate a food literacy instrument specific to individuals with type 2 diabetes mellitus (T2DM). METHODS Twelve T2DM-specific, food literacy-related statements underwent content validity and face validity testing, and exploratory factor analysis (EFA) was conducted (phase 1). The 6 statements remaining after EFA testing were added to an existing food literacy questionnaire called the Eating and Food Literacy Behaviors Questionnaire (EFLBQ). Confirmatory factor analysis (CFA) examined the EFLBQ plus the T2DM-specific statements, and the instrument was called the Eating and Food Literacy Questionnaire for Diabetics (EFLBQ-D; phase 2). Both EFA and CFA were administered by third-party provider Centiment via Qualtrics to adults with T2DM residing in the 13 United States Department of Agriculture Southern region states. Reliability was assessed via point estimate reliability testing. RESULTS The EFA items clustered into 2 factors each with 3 statements: (1) carbohydrate counting and nutrition label reading and (2) healthy food preparation methods. The CFA indicated that the EFLBQ-D had good fit and that the factors had good reliability. The EFLBQ's integrity was maintained with its items loading on the respective constructs. CONCLUSIONS The EFLBQ-D appears to be a valid, reliable instrument for use by researchers and professionals to better understand food behaviors and food literacy skills of those with T2DM. This is an important tool to help individualize medical nutrition therapy, improving patient care in this population.

The Eating and Food Literacy Behaviors Questionnaire Has the Capacity to Distinguish Between Food Literacy Scores of Students Enrolled in Senior-Level Nutrition Classes Compared With Those Students Registered in Other Academic Courses Attending a University in the Southeastern United States. J Acad Nutr Diet 2024; 124:740-746. [PMID: 37956719 DOI: 10.1016/j.jand.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 10/26/2023] [Accepted: 11/09/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND The Eating and Food Literacy Behaviors Questionnaire (EFLBQ) is an instrument that has not been tested for its capacity to distinguish among individuals assumed to have higher and lower food literacy. OBJECTIVE The aim of this study was to examine and compare EFLBQ scores among university students with and without formal nutrition-related training. DESIGN This study had a cross-sectional design. PARTICIPANTS AND SETTINGS Two hundred twenty-seven young adult university students enrolled in non-nutrition-related classes (n = 76), introductory nutrition classes (n = 98), and senior-level nutrition classes (n = 53) were recruited from a large university in the southeastern United States during the spring and fall semesters of 2022. The students ranged in age from 18 to 30 years. MAIN OUTCOME MEASURES Mean EFLBQ total scores and factor scores of health and nutrition, taste, food preparation, planning and decision making, and convenience were compared among the three groups. STATISTICAL ANALYSES Linear regression backward method examined whether level of training, age, sex, race and ethnicity, and BMI were independent variables associated with total EFLBQ mean scores. Analysis of variance (ANOVA) compared normally distributed data and Kruskal-Wallis and Mann-Whitney U tests compared non-normally distributed data. RESULTS Linear regression testing found that the level of nutrition training was significantly associated with total EFLBQ scores. Students in senior-level nutrition classes had higher total EFLBQ mean scores (M = 3.1 ± 0.2) than students in non-nutrition-related classes (M = 2.9 ± 0.3) (P = 0.002; 95% CI = 0.055, 0.280) and introductory nutrition classes (M = 2.9 ± 0.3) (P = 0.001; 95% CI = 0.275, 0.061). Total EFLBQ mean scores were not different among the students in non-nutritional-related classes and introductory nutrition classes (P = 1.000; 95% CI = -0.096, 0.096). Scores differed by training level for items measuring EFLBQ Factor 1: Health and Nutrition. Factor 1 mean scores were higher in students in senior-level classes (M = 3.1 ± 0.4) than for those in non-nutrition classes (M = 2.7 ± 0.5) (P < 0.001; 95% CI = 0.294, 0.670) and introductory nutrition classes (M = 2.8 ± 0.5) (P < 0.001; 95% CI = 0.228, 0.553). The other EFLBQ factor mean scores were not different among the three groups (all P-values > 0.12). CONCLUSION The EFLBQ demonstrated the capacity to distinguish food literacy scores between students expected to have higher as compared with lower food literacy.

Abstract
OBJECTIVES Students who obtain food from a campus food pantry may benefit from participating in a nutrition/cooking intervention. PARTICIPANTS AND METHODS Twenty-seven students 18-30 years of age attending a university in the southeastern US participated in the IRB approved study. One 2-hour class was offered each week for four weeks in the on-campus cooking laboratory. Subjects indicated how often they cooked a dinner meal at home and completed the Eating and Food Literacy Behaviors Questionnaire (EFLBQ) before and after participating in the program. RESULTS The total EFLBQ, Factor 1 (Health and Nutrition) and Factor 3 (Food Preparation) scores, and the frequency of cooking a dinner meal at home were all higher post-program (all p < 0.05). CONCLUSIONS This pilot study suggests that an on-campus cooking program can increase the food literacy and frequency of cooking meals by university students who obtained items from the campus food pantry.

Abstract
This cross-sectional study aimed to assess the relationship between self-perceived food literacy (SPFL) and quality of overall diet and main meals in Japanese adults. In total, 5998 adults aged 20-79 years were included in this analysis. The SPFL was assessed using the Japanese version of the 29-item Dutch SPFL scale (score range 1-5). Using validated dietary information, the Healthy Eating Index-2015 (HEI-2015) was calculated (score range 0-100). The mean SPFL was 3.18; the internal consistency of the overall scale was considered good (Cronbach's alpha: 0.80). The mean HEI-2015 for overall diet was 50.4. The SPFL was significantly and positively associated with the HEI-2015. Using multiple linear regression, one point increase of SPFL corresponded to an increase in HEI-2015 by a point of 4.8 for overall diet, 6.2 for breakfast, 4.6 for lunch, and 3.6 for dinner (all P < 0.0001). Six of the eight domains of SPFL (i.e., food preparation skills, resilience and resistance, healthy snack styles, examining food labels, healthy budgeting, and healthy food stockpiling) were significantly associated with the HEI-2015 for overall diet. When the HEI-2015 for each meal was examined, the domains showing significant associations with all three meals included food preparation skills, healthy snack styles, and healthy budgeting. The healthy food stockpiling was associated with the HEI-2015 for breakfast and lunch, but not dinner. The social and conscious eating and daily food planning were associated with the breakfast HEI-2015 only, with the resilience and resistance associated with the dinner HEI-2015 only. In conclusion, the SPFL was cross-sectionally associated with the quality of overall diet and main meals in Japanese adults. Further observation and intervention studies are needed to confirm the associations observed here.

Abstract
BACKGROUND The repercussions of food insecurity are widely recognized to negatively impact overall health and are influenced by a complex interplay of physiological, psychological, social, and environmental factors. METHODS This study examined the disparities in food consumption and literacy between among food security households and food insecurity households using data from the Korea Rural Economic Institute's 2022 Consumer Behavior Survey for Food, which involved 3,321 respondents. RESULTS Food security households had a greater understanding of and better attitude toward healthier food choices than food insecurity households. Economic ability was identified as having the most significant association with food purchasing behavior, with food security households spending more on average than food insecurity households. Structural equation modeling demonstrated the association of knowledge and attitude with dietary implementation and underscored the significance of consumer literacy as a factor related to willingness to pay for healthier foods. CONCLUSIONS This study underscores the intertwined relationships among financial capacity, knowledge, and health-conscious dietary choices. It also suggests the need for targeted interventions addressing economic and educational gaps to foster healthier food consumption patterns across different socioeconomic contexts.

Abstract
AIM This study aimed to evaluate the impact of food literacy and sustainable consumption behaviors on nutritional status during the pandemic in Turkey. METHODS The study was conducted between May and July 2021 with a questionnaire delivered in a digital environment (social media, Twitter/Facebook/Instagram) to 200 volunteer adults aged 20-65. With this questionnaire form, sociodemographic characteristics, general information, and consumer behaviors of the individuals were obtained. Anthropometric measurements (height, body weight, body mass index (BMI), waist circumference, hip circumference, waist/hip ratio, and waist/height ratio) of the individuals were recorded online as self-report. The Self Perceived Food Literacy (SPFL) Scale was administered to measure nutritional literacy levels. To measure the sustainable consumption behaviors of the individuals, the Sustainable Consumption Behavior (SCB) Scale was administered. RESULTS We found that 87.2% of women and 40% of men had heard of sustainable nutrition before (p < 0.001). The mean total score of SCB was statistically significantly higher in women than in men (3.1 ± 0.48 in women, 2.9 ± 0.69 in men, p < 0.05). The mean score of SPFL was 3.31 ± 0.275 in women, while it was 3.05 ± 0.395 in men. There was a statistically significant relationship between SPFL mean scores and gender (p < 0.05). CONCLUSION There was a statistically significant negative relationship between SPFL score and BMI, body weight, and waist/hip ratio. There was a statistically significant negative relationship between the SCB and waist/hip ratio. Food literacy and sustainable consumption behaviors are associated with anthropometric measurements. Sustainable nutrition, sustainable consumption behaviors, and food literacy should be considered as a whole. Trainings should be increased to raise awareness of individuals about food literacy.

Prevalence and Correlates of Dietary and Nutrition Information Seeking Through Various Web-Based and Offline Media Sources Among Japanese Adults: Web-Based Cross-Sectional Study. JMIR Public Health Surveill 2024; 10:e54805. [PMID: 38354021 PMCID: PMC10902774 DOI: 10.2196/54805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 12/20/2023] [Accepted: 12/22/2023] [Indexed: 02/16/2024] Open
Abstract
BACKGROUND The advent of the internet has changed the landscape of available nutrition information. However, little is known about people's information-seeking behavior toward healthy eating and its potential consequences. OBJECTIVE We aimed to examine the prevalence and correlates of nutrition information seeking from various web-based and offline media sources. METHODS This cross-sectional study included 5998 Japanese adults aged 20 to 79 years participating in a web-based questionnaire survey (February and March 2023). The dependent variable was the regular use of web-based and offline media as a reliable source of nutrition information. The main independent variables included health literacy, food literacy, and diet quality, which were assessed using validated tools, as well as sociodemographic factors (sex, age, education level, and nutrition- and health-related occupations). RESULTS The top source of nutrition information was television (1973/5998, 32.89%), followed by web searches (1333/5998, 22.22%), websites of government and medical manufacturers (997/5998, 16.62%), newspapers (901/5998, 15.02%), books and magazines (697/5998, 11.62%), and video sites (eg, YouTube; 634/5998, 10.57%). Multivariable logistic regression showed that higher health literacy was associated with higher odds of using all the individual sources examined; odds ratios (ORs) for 1-point score increase ranged from 1.27 (95% CI 1.09-1.49) to 1.81 (95% CI 1.57-2.09). By contrast, food literacy was inversely associated with the use of television (OR 0.65, 95% CI 0.55-0.77), whereas it was positively associated with the use of websites of government and medical manufacturers (OR 1.98, 95% CI 1.62-2.44), books and magazines (OR 2.09, 95% CI 1.64-2.66), and video sites (OR 1.53, 95% CI 1.19-1.96). Furthermore, diet quality was positively associated with the use of newspapers (OR 1.02, 95% CI 1.01-1.03) and books and magazines (OR 1.03, 95% CI 1.02-1.04). Being female was associated with using television and books and magazines, whereas being male was associated with using websites of government and medical manufacturers, newspapers, and video sites. Age was positively associated with using newspapers and inversely associated with using websites of government and medical manufacturers and video sites. People with higher education were more likely to refer to websites of government and medical manufacturers and newspapers but less likely to use television and video sites. Dietitians were more likely to use websites of government and medical manufacturers and books and magazines than the general public but less likely to use television and video sites. CONCLUSIONS We identified various web-based and offline media sources regularly used by Japanese adults when seeking nutrition information, and their correlates varied widely. A lack of positive associations between the use of the top 2 major sources (television and web searches) and food literacy or diet quality is highlighted. These findings provide useful insights into the potential for developing and disseminating evidence-based health promotion materials.

Abstract
In 2019, Health Canada released a new iteration of Canada's Food Guide (2019-CFG), which, for the first time, highlighted recommendations regarding eating practices, i.e., guidance on where, when, why, and how to eat. The objective of this study was to develop a brief self-administered screener to assess eating practices recommended in the 2019-CFG among adults aged 18-65 years. Development of the screener items was informed by a review of existing tools and mapping of items onto 2019-CFG recommendations. Face and content validity were assessed with experts in public health nutrition and/or dietary assessment (n = 16) and individuals from Government of Canada (n = 14). Cognitive interviews were conducted with English-speaking (n = 16) and French-speaking (n = 16) adults living in Canada to assess face validity and understanding of the screener items. While some modifications were identified to improve relevance or clarity, overall, the screener items were found to be relevant, well-constructed, and clearly worded. This comprehensive process resulted in the Canadian Eating Practices Screener/Questionnaire court canadien sur les pratiques alimentaires, which includes 21 items that assess eating practices recommended in the 2019-CFG. This screener can facilitate monitoring and surveillance efforts of the 2019-CFG eating practices as well as research exploring how these practices are associated with various health outcomes.

Public Health Nutr 2023; 26:2945-2952. [PMID: 37850441 PMCID: PMC10755447 DOI: 10.1017/s1368980023002148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 07/30/2023] [Accepted: 09/29/2023] [Indexed: 10/19/2023]
Abstract
OBJECTIVE We examined whether associations between the food environment, frequency of home cooking, diet quality and BMI were modified by the level of cooking skills. DESIGN Cross-sectional study using linear and modified Poisson regression models adjusted for age, sex, energy intake, education, income, household size and urbanisation. The frequency of home cooking was categorised into <6 and 6-7 d. Diet quality was based on a validated Dutch healthy diet index (0-150 points). Count of restaurants and food stores were determined by their count in a 1000m buffer around home and work. Cooking skills (score 1-5) were assessed using a validated questionnaire and added as interaction term. SETTING The Netherlands. PARTICIPANTS 1461 adults aged 18-65 years. RESULTS Count of restaurants and food stores were not associated with the frequency of home cooking. A 10-unit higher count of food stores was associated with a higher diet quality (β: 0·58 (95 % CI (0·04, 1·12)), and a 10-unit higher count of restaurants was associated with a lower BMI kg/m2 (β: -0·02 (95 % CI (-0·04, -0·004)). Better cooking skills were associated with a higher likelihood of cooking 6-7 d compared with <6 d (risk ratio: 1·24 (95 % CI (1·16, 1·31)) and a higher diet quality (β: 4·45 (95 % CI (3·27, 5·63)) but not with BMI. We observed no interaction between the food environment and cooking skills (P-for-interaction > 0·1). CONCLUSIONS Exposure to food stores was associated with a higher diet quality and exposure to restaurants with a lower BMI. Better cooking skills were associated with a higher frequency of home cooking and better diet quality but did not modify associations with the food environment. Future studies should explore different approaches to understand how individuals interact with their food environment.

Associations of food choice values and food literacy with overall diet quality: a nationwide cross-sectional study in Japanese adults. Br J Nutr 2023; 130:1795-1805. [PMID: 37017207 PMCID: PMC10587391 DOI: 10.1017/s000711452300082x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/28/2023] [Accepted: 03/22/2023] [Indexed: 04/06/2023]
Abstract
To date, a limited number of studies have examined aspects of food choice values and food literacy in relation to some aspects of dietary behaviours. The aim of this cross-sectional study was to comprehensively examine the associations of food choice values and food literacy with diet quality. In total, 2231 Japanese adults aged 19-80 years completed questionnaires asking about food choice values (accessibility, convenience, health/weight control, tradition, sensory appeal, organic, comfort and safety) and food literacy characterised by nutrition knowledge, cooking skills, food skills and eating behaviours (hunger, food responsiveness, emotional overeating, enjoyment of food, satiety responsiveness, emotional undereating, food fussiness and slowness in eating). As a measure of diet quality, the Healthy Eating Index-2015 (HEI-2015) was calculated using a brief-type diet history questionnaire (BDHQ) or a food combination questionnaire (FCQ). In males, after adjustment for potential confounding factors (including age, BMI and the ratio of reported energy intake to estimated energy requirement), the HEI-2015 derived from BDHQ and that derived from FCQ were associated significantly (P ≤ 0·02) and positively with the food choice values of organic and inversely with food fussiness. In females, the HEI-2015 showed positive associations with the food choice values of health/weight control, nutrition knowledge and cooking skills and an inverse association with food fussiness, irrespective of the dietary assessment questionnaire (P ≤ 0·03). In conclusion, this study suggests that several aspects of food choice values and food literacy were associated with diet quality, and the aspects related differed between males and females.

Abstract
Nutrition and food literacy are two important concepts that are often used interchangeably, but they are not synonymous. Nutrition refers to the study of how food affects the body, while food literacy refers to the knowledge, skills, and attitudes necessary to make informed decisions about food and its impact on health. Despite the growing awareness of the importance of food literacy, food illiteracy remains a global issue, affecting people of all ages, backgrounds, and socioeconomic status. Food illiteracy has serious health implications as it contributes to health inequities, particularly among vulnerable populations. In addition, food literacy is a complex and multidisciplinary field, and there are numerous challenges to health communication that must be addressed to effectively promote food literacy and improve health outcomes. Addressing food illiteracy and the challenges to health communication is essential to promote health equity and improve health outcomes for all populations.

An assessment before the front-of-package labelling policy. Food Res Int 2023; 172:113107. [PMID: 37689875 DOI: 10.1016/j.foodres.2023.113107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 06/02/2023] [Accepted: 06/09/2023] [Indexed: 09/11/2023]
Abstract
Front-of-package labelling is a measure that can facilitate consumption of healthier foods. This study examined the predictors of consumers' intentions to use food labelling to make healthy food choices and prevent non-communicable diseases before the implementation of the front-of-package labelling policy in Brazil. An extended theory of planned behaviour incorporating knowledge and food literacy served as the theoretical foundation. First, experts (n = 6) and the target population (n = 30) validated the questionnaire, and the validation data were analysed using content validity coefficients (CVC). An online questionnaire was administered to 783 participants, and data were collected between May and October 2022. Partial least squares structural equation modelling (PLS-SEM) was used to test the prediction hypothesis. The questionnaire showed adequate content validity, with all indicators of CVC ≥ 0.75. In the PLS-SEM attitudes (p < 0.001), subjective norms (p < 0.001), knowledge (p < 0.001), and food literacy (p < 0.001) positively predicted the intention to use food labels to make healthy food choices, confirming the main hypothesis. Also, Food literacy and knowledge predicted all constructs of the theory of planned behaviour (p < 0.001). The results highlight the importance of providing nutritional knowledge and food literacy, developing nutritional skills and abilities to encourage consumers to make healthy food choices, and to strengthen other policies such as front-of-package labelling.

Nutr Res Pract 2023; 17:945-958. [PMID: 37780226 PMCID: PMC10522808 DOI: 10.4162/nrp.2023.17.5.945] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 04/24/2023] [Accepted: 06/21/2023] [Indexed: 10/03/2023] Open
Abstract
BACKGROUND/OBJECTIVES Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.

A Novel Mobile App for Personalized Dietary Advice Leveraging Persuasive Technology, Computer Vision, and Cloud Computing: Development and Usability Study. JMIR Form Res 2023; 7:e46839. [PMID: 37549000 PMCID: PMC10442736 DOI: 10.2196/46839] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/23/2023] [Accepted: 05/10/2023] [Indexed: 08/08/2023] Open
Abstract
BACKGROUND The Australian Dietary Guidelines (ADG) translate the best available evidence in nutrition into food choice recommendations. However, adherence to the ADG is poor in Australia. Given that following a healthy diet can be a potentially cost-effective strategy for lowering the risk of chronic diseases, there is an urgent need to develop novel technologies for individuals to improve their adherence to the ADG. OBJECTIVE This study describes the development process and design of a prototype mobile app for personalized dietary advice based on the ADG for adults in Australia, with the aim of exploring the usability of the prototype. The goal of the prototype was to provide personalized, evidence-based support for self-managing food choices in real time. METHODS The guidelines of the design science paradigm were applied to guide the design, development, and evaluation of a progressive web app using Amazon Web Services Elastic Compute Cloud services via iterations. The food layer of the Nutrition Care Process, the strategies of cognitive behavioral theory, and the ADG were translated into prototype features guided by the Persuasive Systems Design model. A gain-framed approach was adopted to promote positive behavior changes. A cross-modal image-to-recipe retrieval model under an Apache 2.0 license was deployed for dietary assessment. A survey using the Mobile Application Rating Scale and semistructured in-depth interviews were conducted to explore the usability of the prototype through convenience sampling (N=15). RESULTS The prominent features of the prototype included the use of image-based dietary assessment, food choice tracking with immediate feedback leveraging gamification principles, personal goal setting for food choices, and the provision of recipe ideas and information on the ADG. The overall prototype quality score was "acceptable," with a median of 3.46 (IQR 2.78-3.81) out of 5 points. The median score of the perceived impact of the prototype on healthy eating based on the ADG was 3.83 (IQR 2.75-4.08) out of 5 points. In-depth interviews identified the use of gamification for tracking food choices and innovation in the image-based dietary assessment as the main drivers of the positive user experience of using the prototype. CONCLUSIONS A novel evidence-based prototype mobile app was successfully developed by leveraging a cross-disciplinary collaboration. A detailed description of the development process and design of the prototype enhances its transparency and provides detailed insights into its creation. This study provides a valuable example of the development of a novel, evidence-based app for personalized dietary advice on food choices using recent advancements in computer vision. A revised version of this prototype is currently under development.

Abstract
OBJECTIVES This study was conducted to examine the differences in food literacy between adults and older adults and the association of food literacy with food group intake. METHODS In total, 4,039 participants from the 2021 Survey for Food Consumption in Seoul were included in this study. The intake of whole grains, high-protein foods, total vegetables, vegetables excluding kimchi and pickles, fresh fruits, and milk and dairy products was assessed using a simple food frequency questionnaire. Food literacy was measured using a food literacy measurement questionnaire. RESULTS With the exception of milk and dairy, adults had a significantly higher proportion of insufficient food intake than older adults (p<0.001). Both adults and older adults with sufficient food group consumption had higher food literacy scores. Notably, the difference in food literacy scores by level of food intake was highest for fresh fruits (p<0.001). After adjusting for confounding factors affecting food literacy scores, a higher score was associated with a lower probability of having insufficient food intake in all food groups for both adults and older adults. Specifically, those in the highest food literacy score quartile were less likely to have insufficient intake of vegetables (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.28 to 0.43) and fresh fruits (OR, 0.32; 95% CI, 0.24 to 0.43), compared to the lowest quartile. CONCLUSIONS Improving food literacy is an important factor for promoting healthy food intake in older adults as well as adults. Therefore, it is necessary to develop intervention programs to work toward this goal.

Abstract
OBJECTIVE Low dietary guideline adherence is persistent, but there is limited understanding of how individuals with varying socio-economic backgrounds reach a certain dietary intake. We investigated how quantitative and qualitative data on dietary guidelines adherence correspond and complement each other, to what extent determinants of guideline adherence in quantitative data reflect findings on determinants derived from qualitative data and which of these determinants emerged as interdependent in the qualitative data. DESIGN This mixed-methods study used quantitative questionnaire data (n 1492) and qualitative data collected via semi-structured telephone interviews (n 24). Quantitative data on determinants and their association with total guideline adherence (scored 0-150) were assessed through linear regression. Directed content analysis was used for qualitative data. SETTING Dutch urban areas. PARTICIPANTS Adults aged 18-65 years. RESULTS A range of determinants emerged from both data sources, for example higher levels of cognitive restraint (β 5·6, 95 % CI 4·2, 7·1), habit strength of vegetables (β 4·0, 95 % CI 3·3, 4·7) and cooking skills (β 4·7, 95 % CI 3·5, 5·9), were associated with higher adherence. Qualitative data additionally suggested the influence of food prices, strong dietary habits and the social aspect of eating, and for the determinants cognitive restraint, habit strength related to vegetables, food prices and home cooking, some variation between interviewees with varying socio-economic backgrounds emerged in how these determinants affected guideline adherence. CONCLUSIONS This mixed-methods exploration provides a richer understanding of why adults with varying socio-economic backgrounds do or do not adhere to dietary guidelines. Results can guide future interventions promoting healthy diets across populations.

Guiné RPF, Florença SG, Aparício MG, Cardoso AP, Ferreira M. Food Knowledge for Better Nutrition and Health: A Study among University Students in Portugal. Healthcare (Basel) 2023; 11:healthcare11111597. [PMID: 37297738 DOI: 10.3390/healthcare11111597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 05/15/2023] [Accepted: 05/25/2023] [Indexed: 06/12/2023] Open
Abstract
When students enter university, they suffer adaptations, including, usually, greater autonomy and responsibility for the choices they make. Therefore, it is crucial that they are well informed so as to make healthier food choices. The aim of this study was to determine whether sociodemographic characteristics, academic performance and lifestyle (tobacco and alcohol consumption) interfere with food literacy in university students. A quantitative, analytical, descriptive, transversal and correlational study was carried out, using quantitative data obtained through a questionnaire survey applied to a sample of 924 university students in Portugal. Food literacy was assessed through a scale of 27 items, distributed in three dimensions: D1-Literacy about food nutritional value and composition, D2-Literacy about labelling and food choice and D3-Literacy about healthy eating practices. Results showed no differences in food literacy according to sex or age. However, food literacy varied significantly with nationality, either globally (p = 0.006) or in the different dimensions evaluated (p-values of 0.005, 0.027 and 0.012 for D1, D2 and D3, respectively). In terms of academic achievement, the results showed no significant differences according to self-reported academic performance or even to the average classification obtained in the course. Regarding lifestyle variables, it was observed that alcohol consumption or smoking are not associated with food literacy, that is, food literacy does not vary significantly with these two lifestyle variables. In conclusion, food literacy in general and the dimensions evaluated are essentially constant among university students in Portugal, only varying for students from abroad. These results help to better perceive the food literacy levels for the population under study, university students, and that can be a valuable tool to better increase food literacy at these institutions as a way to better prepare for a healthier life and proper food habits that can enhance health in the long term.

Abstract
Purpose The familial food environment is influenced by many factors, including food insecurity, food accessibility, and foods accepted by the family. These factors can facilitate or hinder caregivers' ability to support a healthy home food environment. The aim of this research was to explore the barriers to, perspectives on, and nutrition education needs identified by food-insecure parents which would then inform a community-based nutrition education program. Methods A qualitative study used focus group data that were recorded, transcribed verbatim, and analyzed using a constant comparison approach to categorize the emerging themes. Results Emergent themes: (1) Cooking confidence deficit; (2) Healthy meal preparation barriers; (3) Healthy meal acceptance barriers; (4) Meal planning, management, and adaptability. These themes suggest that supporting a healthy home food environment is connected to both food knowledge and competencies, known as food literacy. Conclusion Food literacy competency should be assessed before nutrition education program implementation within community settings.

Abstract
BACKGROUND Healthy eating can improve the course of type 2 diabetes mellitus (T2DM) considerably. As changing eating behaviors in everyday is challenging, there is a need for a nutritional strategy with an eye for everyday life of people with T2DM. A theory centered around the everyday life context is salutogenesis. Salutogenic principles have been operationalized in a new nutritional program for T2DM on food literacy and well-being: the Salutogenic Intervention for Type 2 Diabetes (SALUD) program. OBJECTIVE This study aims to describe the protocol of the invention study that will examine the quantitative and qualitative effects of the SALUD program. METHODS A semiblinded randomized controlled trial will be performed in the Netherlands. A sample size of 56 (including a 30% dropout rate) people with T2DM has been calculated, of whom half (n=28, 50%) will follow the SALUD program (intervention) and half (n=28, 50%) will receive usual care (control). Recruitment strategies consist of advertisement via local health care professionals, posters, social media, and local newspapers. The SALUD program consists of 12 weekly web-based group sessions under the supervision of a certified lifestyle coach. Fidelity of the delivery is guaranteed by selecting a salutogenic coach, use of an intervention manual, training of the coach, weekly evaluation forms, and recording several sessions. The theoretical salutogenic principle of the intervention is mobilizing 2 important psychosocial resources required for organizing healthy eating in everyday life: self-identity and social support. Measurements will be performed at 3 times: at baseline (T0), after 12 weeks (postintervention; T1), and after 24 weeks (follow-up; T2). The primary outcome is food literacy, measured with the self-perceived food literacy scale questionnaire (expected effect size=0.9). Secondary outcomes are self-efficacy, quality of life, sense of coherence, diet quality, body weight, BMI, and waist-hip ratio. All outcomes will be tested with linear mixed models, following an intention-to-treat approach and standard principles of randomized controlled trials. In addition, a qualitative analysis will be performed. RESULTS The proposed study will provide useful information on the effects of a salutogenic program on healthy eating and well-being in people with T2DM in everyday life. Recruitment started on October 1, 2021. The intervention participants followed the SALUD program between January and August, 2022. The acquisition of the data was completed on August 1, 2022; publications are expected in 2023. CONCLUSIONS This study will be one of the first salutogenic interventions for T2DM, which will provide valuable information on what salutogenic intervention entail. The SALUD program may serve as a concrete, web-based tool. The combination of quantitative and qualitative measures allows a comprehensive evaluation of effects. These insights can be used for further optimalization of T2DM interventions. TRIAL REGISTRATION Netherlands Trial Registry, NL8963; https://trialsearch.who.int/Trial2.aspx?TrialID=NL8963.

Abstract
BACKGROUND The metabolic health of urban Ugandans, mostly females, is increasingly becoming sub-optimal. OBJECTIVES We assessed the effect of a complex lifestyle intervention, based on a small change approach, on metabolic health among females of reproductive age in urban Uganda. METHODS A cluster randomized controlled two-arm trial with a 1:1 allocation involving church communities in Kampala (Uganda) was undertaken. The intervention arm received infographics and face-to-face group sessions, whereas the comparison arm received infographics only. Eligible participants were aged 18 to 45 years with a waist circumference of ≥80 cm and without cardiometabolic diseases. The study included a 3-month intervention and a 3-month postintervention follow-up. The primary outcome was a reduction in waist circumference. Secondary outcomes included optimization of cardiometabolic health, physical activity, and fruit and vegetable intake. Intention to treat analyses were performed using linear mixed models. This trial was registered at clinicaltrials.gov as NCT04635332. RESULTS The study was conducted between 21 November 2020 and 8 May 2021. Six church communities were randomly selected, 3 (n = 66) per study arm. At 3 months and postintervention follow-up, 118 and 100 participants were analyzed, respectively. At 3 months, waist circumference tended to be lower in the intervention arm (-1.48 cm (95% CI: -3.05, 0.10) P = 0.06). The intervention showed an effect on fasting blood glucose concentrations (-6.95 mg/dL (95% CI: -13.37, -0.53) P = 0.034). Participants in the intervention arm consumed more fruits (62.6 g (95% CI: 1.9, 123.3) P = 0.046) and vegetables (66.2 g (95% CI: 25.5, 106.8) P = 0.002), whereas physical activity increased with no notable differences across the study arms. At 6 months, we found an intervention effect on waist circumference (-1.87 cm (95% CI: -3.32, -0.44) P = 0.011), fasting blood glucose concentration (-6.48 mg/dL (95% CI: -12.76, -0.21) P = 0.043), fruit consumption (29.7 g (95% CI: 5.8, 53.7) P = 0.015), and physical activity (2675.1 MET-mins/wk (95% CI: 1045.7, 4304.4) P = 0.001). CONCLUSIONS The intervention improved and sustained physical activity and fruit and vegetable intake, but these changes were accompanied by minimal cardiometabolic health improvements. If maintained over time, the attained lifestyle improvements may result in substantial cardiometabolic health improvements.

Abstract
BACKGROUND Consumption of avocados has been suggested to be beneficial for weight control, however, limited research is available about the related food choices. Understanding the food choices associated with avocados at meal occasions may further aid behavioural strategies to lose weight. The present study used a systematic approach to develop an avocado-specific food database, with the aim to explore food choices related to avocados at meal occasions as reported by overweight and obese volunteers in weight loss clinical trials. METHODS The avocado-specific database was based on AUSNUT 2011-13 food composition database structure and was developed via a systematic approach, which determined the avocado content of Australian foods and beverages. Baseline usual food intake data was retrospectively pooled from four food-based clinical trials (n = 758). The Apriori algorithm of association rules, a two-step descriptive method was used to identify food choices associated with avocados at different meal occasions using a nested hierarchical food group classification system. RESULTS The avocado database identified 34 avocados and avocado-containing foods and beverages. The proportion of avocado consumers in the pooled cohort was 51.3% (n = 389), with an average avocado intake of 21.57 ± 36.75 grams per day. Avocados were found to be closely related to other food groups at all of the food group levels at main meal occasions. A total of 68 food items containing avocados were identified for avocado consumers at the breakfast, lunch and dinner meals. CONCLUSION The avocado specific database provides a snapshot of the foods and beverages which contain avocados. Enumerating the full range of food choices in relation to avocado consumption should provide examples of food choices that people might consider in their efforts to increase their avocado consumption.

Japanese school children's intake of selected food groups and meal quality due to differences in guardian's literacy of meal preparation for children during the COVID-19 pandemic. Appetite 2023; 180:106186. [PMID: 35921866 PMCID: PMC9539409 DOI: 10.1016/j.appet.2022.106186] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 07/19/2022] [Accepted: 07/21/2022] [Indexed: 12/15/2022]
Abstract
In 2020, a state of emergency (SOE) was enforced by the Japanese government, which included temporary school closures with the aim of overcoming COVID-19 spread, which prevented access to school lunches. We evaluated the relationship between meal quality and guardians' literacy of meal preparation for a nationally representative sample of 1107 Japanese schoolchildren (aged 10-14 years) before, during, and after the SOE on the basis of 7 questions scored using a 5-point Likert scale. The guardians' literacy of meal preparation for children was divided into quartiles, with Q1 and Q4 including participants with the lowest and highest scores on food literacy, respectively. School lunch menu was handed out monthly to each household by their classroom teacher. The consumption of (i) meat, fish, or eggs and (ii) vegetables at least twice a day indicated "well-balanced dietary intake", which was less frequent in all four quartiles, especially for Q1 and Q2, during compared to before the SOE. The relative risk increases (95% CI) were Q1: -40.6% (-41.4% to -39.8%; p < 0.001), Q2: -34.0% (-34.7% to -33.3%; p < 0.001), Q3: -13.1% (-13.8% to -12.4%; p < 0.001), and Q4: -15.3% (-16.0% to -14.7%; p < 0.001), adjusted for sex, age, BMI, equivalent income adjusted for the number of household members, and educational level of parents. The interaction p was <0.001 for Q1-3 vs. Q4. Guardians with low total scores were significantly more likely to have less time, mental capacity, and financial ability to prepare meals after the SOE. Therefore, schoolchildren's meal quality deteriorated during the SOE, particularly among those with guardians with low food literacy even after adjustment for household income level and guardians' educational level.

Abstract
Widespread patterns of poor dietary behavior are a key factor causing the increasing prevalence of chronic diseases around the world. Research has provided initial insights into the potential of food literacy (FL) to empower individuals to improve their dietary behavior. However, studies on FL interventions in working adults are scarce. The intervention delivered in this study was a comprehensive 3-week full time education-based workplace health promotion program (WHPP) that provided the participants with in-depth knowledge and skills regarding nutrition and health. We aimed to investigate the short- and long-term effects of the WHPP on FL and dietary intake (DI) and to examine the association between FL and DI in a sample of 144 German office workers (30.0% female). Using two random intercept mixed linear regression models, we found significant strong improvements for both FL (β = 0.52, p < 0.0001) and DI (β = 0.63, p < 0.0001) after the WHPP when compared to baseline. Significant long-term improvements at 18 months were strong for FL (β = 0.55, p < 0.0001) and weak for DI (β = 0.10, p < 0.0001). FL showed a significant moderate effect on DI across all measurement time points (β = 0.24, p < 0.0001). We conclude that well-designed WHPPs can induce long-term improvements in FL and DI, and that FL can be viewed as an asset to further expand food-related knowledge and skills and to enhance dietary behavior. Our study fills a gap of long-term findings regarding the role of FL in WHPPs and supports the idea of implementing FL in the development of comprehensive WHPPs to improve DI.

Abstract
Food literacy refers to the knowledge and skills related to healthy food choices. The aim of this study is to present the process of the cross-cultural adaptation and content validation of the Short Food Literacy Questionnaire (SFLQ) for the Brazilian population. The process of adaptation and validation of the SFLQ was conducted in four steps: (1) conceptual and item equivalence; (2) translation with semantic equivalence; (3) operational equivalence; (4) measurement equivalence. The study involved ten judges (food and nutrition experts) and 20 subjects (general population) in evaluating the semantic equivalence of the SFLQ. The semantic equivalence was assessed by calculating the content validity coefficient (CVC). All the items had a CVC greater than 0.80 considering all the evaluated parameters. The SFLQ has been adapted for the Brazilian context and guidelines. The adapted version of the questionnaire was referred to as the SFLQ-Br. The operational equivalence was conducted with 120 subjects using an online approach. The measurement equivalence was assessed using confirmatory factor analysis, a reliability assessment, and an instrument stability assessment. A single factor was extracted, and all the items had a factor loading of >0.40 and appropriate goodness-of-fit values. All the equivalence results show that the SFLQ-Br can be used in the Brazilian population as a reliable, consistent, and stable instrument to measure food literacy.

Abstract
Abstract
Background
One of the factors affecting self-care in diabetic patients is food literacy, which helps said patients in following a healthy diet. Thus, it is crucial to analyze food literacy in diabetic patients through suitable and reliable instruments.
Objective
The current study aimed to design a questionnaire for food literacy assessment in diabetic patients and analyze its psychometric features.
Method
The present study was a cross-sectional descriptive analysis carried out in 2021. Firstly, the concepts of food literacy in diabetic patients were identified and the questionnaire was deigned based on them. Secondly, its face and content validities and its reliability were analyzed. Finally, the construct validity was analyzed by exploratory factor analysis. The study was carried out on 300 diabetic participants chosen at random via stratified cluster sampling from Health service centers. The exploratory factor analysis was carried out by extracting the main factors and using varimax rotation with eigenvalue values more than 1.
Results
A five-pronged structure accounted for 52.745% of food literacy variance. This included the ability to read food facts, practical ability to group foods, the ability to identify the caloric content of different foods, the ability to understand the effect of food on health, and the ability to prepare a healthy meal. Items with an impact score below 1.5 were discarded. Additionally, items with CVR scores below 0.62 and CVI scores below 0.79 were deleted too. The Kaiser-Meyer-Okin measurement was 0.836 (p < 0.001). Alpha Cronbach Scale dimension was 0.610–0.951.
Conclusion
The results of this study showed that the exploratory dimensions of the current study were consistent with health literacy measurements, such as functional, interactive, and critical food literacy. This scale has acceptable reliability and validity. Health professionals can use this scale to analyze and improve food literacy in diabetic patients. This is a new instrument and thus far no questionnaire has been made to evaluate food literacy in diabetic patients.

Itzkovitz A, Maggio V, Roy-Fleming A, Legault L, Brazeau AS. Nutrition and food literacy among young Canadian adults living with type 1 diabetes. Diabet Med 2022; 39:e14921. [PMID: 35870142 DOI: 10.1111/dme.14921] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 06/23/2022] [Accepted: 07/21/2022] [Indexed: 11/29/2022]
Abstract
AIM Nutrition and food literacy encompasses knowledge, skills and confidence to prepare healthy meals. This project aimed to assess and compare the proportion of young Canadian adults (18-29 years old) living with type 1 diabetes and without diabetes (controls) who demonstrated adequate nutritional health literacy. METHODS This cross-sectional study involved participants completing an online survey that included questions on socio-economic status, nutrition knowledge, confidence and skills in meal preparation and the Short Food Literacy Questionnaire (SFLQ). Proportion of participants with adequate SFLQ score (i.e. ≥34/52) was compared between the groups (two-sample t-test). RESULTS Among the 236 people living with type 1 diabetes and 191 controls (81.5% women), mean age was 24 ± 3 years for people living with type 1 diabetes and 22 ± 3 years for controls (p < 0.001). More people living with type 1 diabetes reported adequate SFLQ score (people living with type 1 diabetes 88.0% vs. Controls 68.0%; p < 0.001). Similarly, majority of people living with type 1 diabetes prepared their own meals compared to the controls (74.5% vs. 47.6%; p < 0.001). Enhanced SFLQ score was associated with higher cooking skills (p = 0.02) and confidence (p < 0.01) in preparing healthy meals. CONCLUSIONS Living with type 1 diabetes was associated with greater SFLQ scores among young Canadian adults. Having the independence, the confidence and skills in meal preparation were contributing factors.

Thompson C, Byrne R, Adams J, Vidgen HA. Development, validation and item reduction of a food literacy questionnaire (IFLQ-19) with Australian adults. Int J Behav Nutr Phys Act 2022; 19:113. [PMID: 36050778 PMCID: PMC9438317 DOI: 10.1186/s12966-022-01351-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 08/18/2022] [Indexed: 11/24/2022] Open
Abstract
Background Food literacy is theorised to improve diet quality, nutrition behaviours, social connectedness and food security. The definition and conceptualisation by Vidgen & Gallegos, consisting of 11 theoretical components within the four domains of planning and managing, selecting, preparing and eating, is currently the most highly cited framework. However, a valid and reliable questionnaire is needed to comprehensively measure this conceptualisation. Therefore, this study draws on existing item pools to develop a comprehensive food literacy questionnaire using item response theory. Methods Five hundred Australian adults were recruited in Study 1 to refine a food literacy item pool using principal component analysis (PCA) and item response theory (IRT) which involved detailed item analysis on targeting, responsiveness, validity and reliability. Another 500 participants were recruited in Study 2 to replicate item analysis on validity and reliability on the refined item pool, and 250 of these participants re-completed the food literacy questionnaire to determine its test–retest reliability. Results The PCA saw the 171-item pool reduced to 100-items across 19 statistical components of food literacy. After the thresholds of 26 items were combined, responses to the food literacy questionnaire had ordered thresholds (targeting), acceptable item locations (< -0.01 to + 1.53) and appropriateness of the measurement model (n = 92% expected responses) (responsiveness), met outfit mean-squares MSQ (0.48—1.42) (validity) and had high person, item separation (> 0.99) and test–retest (ICC 2,1 0.55–0.88) scores (reliability). Conclusions We developed a 100-item food literacy questionnaire, the IFLQ-19 to comprehensively address the Vidgen & Gallegos theoretical domains and components with good targeting, responsiveness, reliability and validity in a diverse sample of Australian adults. Supplementary Information The online version contains supplementary material available at 10.1186/s12966-022-01351-8.

Abstract
Chinese immigrants living in Western countries are at increased risk for cardiometabolic diseases. Dietary acculturation has been implicated as a potential contributor, but little is known about why diets change post-migration. The purpose of this qualitative research study was to explore how and why diets change post-migration for Chinese immigrants living in Australia. Eleven participants undertook semi-structured interviews exploring and comparing their diets when they lived in China to their post-migration diets. Thematic analysis revealed that participants exhibited changed social structures of meal preparation, and made unacknowledged dietary changes, such as recipe modification, to maintain their traditional Chinese diet post-migration. Implications of both deliberate and unrecognized dietary changes post-migration include connections to increased risk for metabolic disease post-migration.

Abstract
BACKGROUND This study aimed to develop a conceptual framework to better understand food and nutrition literacy and its dimensions and components among Iranian children. METHODS The study included three sub-studies. First, two qualitative studies were conducted to explore experts' and students' perspectives and experiences regarding the topic. A comprehensive qualitative literature review was then conducted to identify food/nutrition literacy definitions and its components in the relevant literature. The data of the above three sub-studies were compiled as text data and were analyzed utilizing MAXQDA2010 software. RESULTS Two main domains, including cognitive and skill domains, emerged from the data analysis. The cognitive domain consisted of food- and nutrition-related knowledge included four subcategories "nutrition knowledge", "lifestyle knowledge", "food safety knowledge", and "knowledge of food and its preparation") as well as "food and nutrition understanding". The skill domain consisted of three dimensions: "functional", "interactive", and "critical" food and nutrition literacy. CONCLUSIONS The developed framework highlights the importance of integrated application of all dimensions of food and nutrition literacy among this population group. It can assist policymakers and curriculum developers in assessing education curricula and developing effective strategies for teaching and learning to increase students' food and nutrition literacy.

Abstract
The obesity problem has reached a critical level and is threatening not only personal health but also public health systems around the world. Obesity in young adults is especially rapidly growing and many studies have confirmed that the best prevention is developing healthy eating habits with the improvement of food and health promotion literacy competencies. In this context, this study diagnoses the present levels of food literacy and health promotion literacy among young adults and explores the relationships between both literacies and their healthy eating habits. A total of 325 young adults in South Korea participated in this research, and the results are as follows. First, all food literacy components, which are food and nutrition knowledge, food skills, and resilience, are positively associated with healthy eating habits. Second, health promotion literacy is also positively associated with young adults’ healthy eating habits. Lastly, unlike the primary information sources, gender has a moderating effect on the relationships between both literacies and healthy eating habits. This indicates that the government and educational sectors should propose more policy supports and solid education systems in order to help young adults develop their food and health promotion literacies for overall well-being in the future.

Abstract
Food literacy is a combination of functional, critical, and relational skills that pave the way for navigating the food system properly, taking personally and contextually available resources into account. The aim was to validate the Spanish version of the self-perceived food literacy scale in university students to explore the factorial structure of it and to correlate food literacy with other variables. The sample was composed of 362 Spanish university students (314 women). The full questionnaire was administered online and also assessed adherence to a Mediterranean diet, impulsivity, and health-related quality of life for convergent validity testing purposes. Confirmatory factor analysis was conducted to determine the factor structure of the food literacy scale. The Spanish version of the scale showed good indices of internal consistency (Cronbach's α = 0.894). Confirmatory factor analysis revealed a five-factor model that had a better fit index than the seven-factor model of the original scale. External validity was assessed by showing significant correlations with the rest of the variables. Therefore, the Spanish version of the scale is a reliable and valid measure of food literacy. It could be used to promote policies at Spanish universities to improve the food-related behaviors of students.

Abstract
OBJECTIVE To create a tool to measure college students' functional, interactive, and critical nutrition literacy. DESIGN (1) Focus group: item generation, (2) expert review, (3) exploratory factor structure analysis, (4) item refinement and modification, (5) factor structure validation, and (6) criterion validation. SETTING Two land-grant college campuses. PARTICIPANTS College students aged between 18 and 24 years. MAIN OUTCOME MEASURES Survey data was used to assess nutrition literacy. ANALYSIS Exploratory factor analysis, confirmatory factor analysis (CFA), item response theory (IRT) analyses, and correlations. RESULTS One-hundred and twenty-three items were generated and tested in an online survey format. Items were eliminated on the basis of face validity, expert feedback, exploratory factor analysis, and CFA/IRT. The 3 measures (functional, interactive, and critical) were analyzed separately. All 3 measures showed reasonable model fit in the CFA/IRT models. Criterion validity showed small to medium effect sizes between measures and fruit/vegetable intake. Reliability estimates met reasonable standards for each measure. CONCLUSIONS AND IMPLICATIONS The Young Adult Nutrition Literacy Tool is a novel instrument that measures all 3 domains of nutrition literacy. Strengths include a rigorous 6-step development process, reasonable psychometric properties, and a large breadth of items.

Abstract
This cross-sectional study of 2231 Japanese adults described food choice values and food literacy in relation to sex, age, and body mass index. We assessed eight food choice values (accessibility, convenience, health/weight control, tradition, sensory appeal, organic, comfort, and safety, using a 25-item scale), as well as food literacy, which was characterized by nutrition knowledge (using a validated 143-item questionnaire), cooking and food skills (using 14- and 19-item scales, respectively), and eight eating behaviors (hunger, food responsiveness, emotional overeating, enjoyment of food, satiety responsiveness, emotional undereating, food fussiness, and slowness in eating, using the 35-item Adult Eating Behavior Questionnaire). Females had higher means of all the variables than males, except for food fussiness. Compared to participants aged 19-39 and/or 40-59 years, those aged 60-80 years had low means of some food choice values (accessibility, convenience, sensory appeal, and comfort), nutrition knowledge, and all the food approach behaviors (hunger, food responsiveness, emotional overeating, and enjoyment of food) and high means of other food choice values (tradition, organic, and safety) and slowness in eating. Age was inversely associated with cooking and food skills in males, whereas the opposite was observed in females. The associations with body mass index were generally weak. These findings serve as both a reference and an indication for future research.

Effects of University Students’ Perceived Food Literacy on Ecological Eating Behavior towards Sustainability. SUSTAINABILITY 2022.

Abstract
Due to the COVID-19 pandemic and industrialized food systems, people’s eating behavior has become seriously restricted. Especially, university students have started to overly depend on processed foods and carnivorous diets, and it places a huge burden on society by inducing the deterioration of health and environmental sustainability. Therefore, this study was undertaken to examine the effects of university students’ perceived food literacy on ecological eating behavior towards sustainability. A total of 395 university students in South Korea participated in this research. First, students’ food literacy components, which are reading labels and budgeting, healthy snack styles, healthy food stockpiling and resilience and resistance, exert positive influences on ecological eating behavior; second, the other two components, which are food preparation skills and social and conscious eating, have no positive impact on ecological eating behavior. Finally, the influences of food literacy on ecological behavior are significantly moderated by gender differences. This suggests that strengthening university students’ food literacy through education is necessary to promote ecological eating behaviors and advance the development of sustainable society.

Abstract
Background: Food literacy (FL) is important as the ability to consider the unique aspects of food in our lives, society, and environment. The main objectives of this study were as follows: (1) to revisit the definition of FL, considering the cultural, relational, and ecological aspects that were often neglected in previous research, and (2) to develop a measurement tool for adults. Methods: Expert workshops, the Delphi survey, the test–retest survey, and one-on-one interviews were conducted. The content validity ratio was calculated from the Delphi survey. The correlation coefficient of each item was measured twice, and the Cronbach’s alpha was calculated. Results: This study proposed a new definition of FL, including future-oriented values, and suggested three main domains with 33 items: (1) 14 questions in nutrition and safety FL (Cronbach’s α = 0.877, average correlation coefficient = 0.70), (2) 8 questions in cultural and relational FL (Cronbach’s α = 0.705, average correlation coefficient = 0.71), and (3) 11 questions in socio-ecological FL (Cronbach’s α = 0.737, average correlation coefficient = 0.61). Conclusions: This newly developed questionnaire should be tested in different populations; however, this questionnaire can be a basis for measuring and improving FL for healthy, joyful, and sustainable diets for adults.

Abstract
Obesity and mental health disorders are rising simultaneously with shifting dietary behavior away from home cooking, toward typically nutrition-poor and energy-dense convenience meals. Food literacy strongly influences nutrition choices. Community-based cooking interventions target barriers to healthy eating and facilitate development of food literacy skills, thereby potentially increasing preparation of home-cooked meals and positively influencing health. This study of 657 healthy Australian adults explored the efficacy of a 7-week cooking program in improving cooking confidence, whether this transferred to behavior surrounding food, and/or affected mental health. Significant post-program improvements in cooking confidence and satisfaction (all p < 0.001, ηp2 1.12 large), ability to change eating habits (p < 0.001) and overcome lifestyle barriers (p = 0.005) were observed for the intervention group but not control. Participation also improved mental and general health (all p < 0.05, ηp2 0.02 small). No changes were observed for acquisition and consumption of food, or nutrition knowledge in either group. This 7-week cooking program built cooking confidence and improved general and mental health but did not change dietary behavior. To further improve nutrition related behaviors associated with better mental health, more effort is needed to recruit those with below-average nutrition knowledge and interest in cooking.

Abstract
This study investigates consumer experiences of food environments and food acquisition practices during the Covid-19 pandemic. Our rapid assessment online survey featured a convenience sample of 2015 individuals from 119 countries, spanning Western Europe, North America, Latin America, Asia-Pacific, and Africa. Data collection took place in April 2020 during the second month of the pandemic. Participants were recruited via existing networks of the United Nations System Standing Committee on Nutrition, through social media, and by snowballing. The majority of participants were female (71.9%), from low- and middle-income countries (51.0%), and working in nutrition or healthcare (39.3%). Qualitative thematic analysis and descriptive statistics reveal a series of common global experiences related to food availability and accessibility, food prices and affordability, food acquisition practices, and food preparation and consumption. The importance of community food participation, food sharing, and resource allocation are highlighted, along with increasing awareness of healthy diets and food waste. We identify ten synergistic policy entry points to: 1) build resilient and equitable food environments resistant to stresses and shocks; 2) harness positive dietary-related behaviors manifested during the pandemic; and, 3) mitigate the projected nutrition crisis and promote sustainable healthy diets for all.

SSM Popul Health 2022; 17:101025. [PMID: 35097184 PMCID: PMC8783096 DOI: 10.1016/j.ssmph.2022.101025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 12/12/2021] [Accepted: 01/11/2022] [Indexed: 12/30/2022] Open
Abstract
We examined whether material and psychosocial resources may explain socioeconomic differences in diet quality. Cross-sectional survey data from 1461 Dutch adults (42.5 (SD 13.7) years on average and 64% female) on socio-demographics, diet quality, psychosocial factors and perceptions of and objective healthiness of the food environment were used in a structural equation model to examine mediating pathways. Indicators for socioeconomic position (SEP) were income, educational, and occupational level and the 2015 Dutch Healthy Diet (DHD15) index assessed diet quality. Material resources included food expenditure, perceptions of healthy food accessibility and healthfulness of the food retail environment. Psychosocial resources were cooking skills, resilience to unhealthy food environments, insensitivity to food cues and healthy eating habits. Higher SEP was associated with better diet quality; Beducation 8.5 (95%CI 6.7; 10.3), Bincome 5.8 (95%CI 3.7; 7.8) and Boccupation 7.5 (95%CI 5.5; 9.4). Material resources did not mediate the association between SEP and diet quality and neither did the psychosocial resources insensitivity to food cues and eating habits. Cooking skills mediated between 13.3% and 19.0% and resilience to unhealthy food environments mediated between 5.9% and 8.6% of the relation between SEP and the DHD15-index. Individual-level factors such as cooking skills can only explain a small proportion of the SEP differences in diet quality. On top of other psychosocial and material resources not included in this study, it is likely that structural factors outside the individual, such as financial, work and living circumstances also play an important role.

The conceptual framework for a combined food literacy and physical activity intervention to optimize metabolic health among women of reproductive age in urban Uganda. BMC Public Health 2022; 22:351. [PMID: 35183134 PMCID: PMC8856934 DOI: 10.1186/s12889-022-12740-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Accepted: 02/08/2022] [Indexed: 11/17/2022] Open
Abstract
Background Metabolic health of urban Ugandans, mostly women, has increasingly become sub-optimal. As women are strategic for family behavioral change and do not meet WHO recommendations regarding dietary and physical activity (PA), there is an urgent need for science-based interventions to tackle unhealthy dietary and PA behaviors. Objective To develop a food literacy and PA promotion intervention to optimise metabolic health among women of reproductive age in urban Uganda. Methodology Steps 1- 6 of the Intervention Mapping protocol were used to design the intervention. Results Notable determinants from Step 1 were health/beauty paradox, nonfactual nutrition information, socio-cultural misconceptions around moderate PA, fruits, and vegetables. Others included gaps in food/PA knowledge, skills, and self-efficacy. We hypothesised that changing the overall existing behaviours in one intervention may meet strong resistance. Thus, we decided to go for gradual stepwise changes. Hence in step 2, three behavioural intervention objectives were formulated; (1) women evaluate the accuracy of nutrition and PA information., (2) engage in moderate intensity PA for at least 150 min a week, and (3) consume at least one portion of vegetables and one portion of fruit every day. Based on the food literacy model, intervention objectives were formulated into performance objectives and matrices of change objectives. In step 3 a combination of eleven behavioural change techniques were selected and translated into practical strategies to effect changes in determinants. In step 4, intervention components and materials were developed. The intervention consists of five interactive group sessions, 150 min each. Infographics on benefits/recommendations, vegetable recipes, and practical tips to eat more fruits, vegetables, and to engage more in PA are included. Personalised goals and action plans tailored to personal metabolic health and lifestyle needs, and environmental opportunities form the basis of the intervention. A randomized controlled trial is being conducted to evaluate the intervention (https://clinicaltrials.gov/ct2/show/NCT04635332). Conclusions The intervention is novel, based on a holistic food literacy model. The intervention is built on determinants specific to urban Uganda, evidence based behavioural change theoretical models and techniques, detailing the hypothesised behavioural change mechanism. If effective, an evidence-based intervention will become available for reference in urban Uganda.

Abstract
OBJECTIVE To assess the relationship between exposure to social media food messages and self-reported adolescent eating outcomes (including food intake, perceived norms and food literacy). DESIGN A cross-sectional survey was used to assess reported exposure to core and non-core food messages (including marketing messages) on social media, as well as reported food intake, perceived norms, food literacy, attitudes, self-regulation, among others. SETTING 18 secondary schools across Flanders, Belgium. PARTICIPANTS 1002 adolescents 11-19 years of age. RESULTS Self-reported exposure to food marketing and overall food messages on social media was positively associated with eating attitudes, behaviours, perceived norms and food literacy among adolescents. Interestingly, the relationship between food exposure and intake was shaped differently depending on food type; descriptive norms mediated the positive relationship between non-core food social media exposure and non-core food intake (e.g. indirect effect estimate on self-reported sweets consumption is 0·005, se 0·002, P < 0·01), while food literacy mediated the positive relationship between core food social media exposure and core food intake (e.g. indirect effect estimate on self-reported vegetable consumption is 0·01, se 0·003, P < 0·000). CONCLUSIONS This study highlights the significance of social media in relation to adolescent eating. There is an opportunity for health professionals to use social media in the promotion of core food among adolescents. We call for relevant policy actions to regulate the marketing of non-core food to adolescents on social media.

Abstract
BackgroundFood literacy refers to all practicalities associated with healthy eating. Current food literacy tools are limited in practical use in clinical practice. Therefore, an integrated food literacy tool (IFLT) to assess food literacy and to personalize food literacy guidance was developed and validated.MethodsFollowing an iterative process, a food literacy framework was developed and food literacy goals were defined. A corresponding food literacy screener (FLS) to assess food literacy was developed along with an algorithm to provide personalized food literacy guidance based on the food literacy assessment. Content validation of the FLS was assessed by a panel of experts, measuring item and scale content validity index (I/S-CVI) and by the target population in semi structured interviews with 15 adults of reproductive age. Subsequently, an online cross-sectional survey was conducted among 114 adults of reproductive age to evaluate the validity of the FLS. Construct validity was examined against both the validated healthy eating and weight self-efficacy scale and against a food frequency questionnaire assessing healthy eating self-efficacy (HESE) and diet quality, respectively. Reliability was assessed with a two-week test-retest. Pearson correlation tests were conducted.ResultsAn IFLT consisting of a FLS and corresponding algorithm to personalize food literacy guidance by prioritizing food literacy goals was developed. The IFLT includes 24 food literacy goals, addressed by 17 FLS items. Every item received a weighting factor based on theory and expert opinion to prioritize food literacy goals according to personal needs. Content validity revealed that the FLS was rated relevant by experts (S-CVI = 0.93) and well-understood by the target population. The FLS has a good construct validity as it was positively correlated with diet quality (r = 0.536, p < 0.001) and with HESE (r = 0.685, p < 0.001). It also showed a good test-retest reliability (r = 0.721, p < 0.001).ConclusionThe newly developed IFLT is a practically applicable, context specific theory-and expert-based dual purpose tool to assess food literacy and to personalize food literacy guidance by prioritizing individuals' food literacy goals to their needs.

Abstract
Numerous weight-loss interventions promoting healthy and weight-reducing eating behavior have been developed over the past years. To evaluate the effectiveness of such interventions for eating behavior change, short, validated and sensitive instruments are needed. In this study series, we developed and validated a new outcome measure to assess health-conscious and weight-controlling eating behavior for the evaluation of weight-loss interventions. The preliminary version of the German eating behavior scale (Skala zumErnährungsverhalten [SEV]) included 40 items. Three studies were conducted to (a) reduce the preliminary item pool, (b) investigate structural validity and internal consistency using exploratory and confirmatory factor analyses (EFA, CFA), as well as McDonald's ω, and (c) test construct validity with physiological and behavioral parameters. Responsiveness to change was also assessed after a 12-week weight-loss intervention. EFA indicated a two-factor solution with health-conscious (hc-EB) and weight-controlling eating behavior (wc-EB) as subscales, CFA confirmed the two-factor solution with acceptable model fit. Internal consistencies of both subscales were also acceptable to good (hc-EB: ω = 0.88; wc-EB: ω = 0.78). Significantly small to moderate correlations to the Healthy Eating Index (r = 0.51) as well as blood glucose (r = 0.31), blood lipids (r = 0.23), and vascular age (r = 0.31) were found, supporting the construct validity of the SEV and its subscales. Both subscales detected intervention-related changes in eating behavior among subjects of a weight-loss intervention with Standardized Response Means of 0.52 and 0.67, indicating good responsiveness of the SEV. In sum, findings provide evidence that the SEV is a valid and responsive measure to assess health-conscious and weight-controlling eating behavior.

Abstract
PURPOSE Nephrology professionals' understanding of food literacy (FL) and influencing factors is significant for nutrition management, which is key to controlling disease progress among non-dialysis patients with chronic kidney disease (CKD). However, few studies have explored FL in CKD patients. Hence, this study aimed to investigate the level of FL of non-dialysis patients with CKD and to analyze influencing factors in China. PATIENTS AND METHODS A total of 203 CKD patients without dialysis were recruited from August to December 2020 to participate in a cross-sectional study. Food literacy was assessed by a modified short food literacy questionnaire for adults. Related influencing factors were measured by the motivation for dietary self-control scale and the satisfaction with dietary behavior scale. Data were also collected regarding patients' health information-seeking behavior (four items), satisfaction and compliance with dietary advice from healthcare professionals (two items), and demographics and clinical diagnoses. RESULTS The mean age of patients was 44.5 years (range 18 to 75), and 42.5% were male. Most (50.2%) were in stages 1-2 of CKD. The mean FL score of these patients was 38.75±0.38. The multivariable linear regression analysis shows that secondary educational level (β=0.221, p=0.004), motivation for controlling diet (β=0.198, p=0.003), satisfaction with dietary behaviors (β=0.319, p<0.001), and health information-seeking behavior (β=0.146, p=0.019) were significant influencing factors. CONCLUSION Food literacy of Chinese CKD patients without dialysis should be improved. Patients with higher education levels exhibit more active information-seeking behaviors, have greater satisfaction with dietary behaviors, and their motivation for dietary self-control is more likely to be associated with better FL. Healthcare workers should be aware of factors influencing FL and attempt to integrate assessment of FL into routine food-related education for CKD patients.

Abstract
Food literacy is a multidimensional construct required to achieve diet quality. The Food Sensations® for Adults (FSA) program aims to improve the food literacy of low to middle-income adults living in Western Australia and is funded by the Western Australian Department of Health. The original published behavior checklist used to measure change in food literacy has been revised based on experience of the facilitators and the iterative development of the program. This research sought to assess the validity and reliability of the improved food literacy behavior checklist. A total of 1,359 participants completed the checklist over an 18-month period. Content, face, and construct validity were considered in the re-development of the checklist. An exploratory factor analysis of the checklist identified three factors: (1) Plan and Manage, (2) Selection, and (3) Preparation. Cronbach’s alpha coefficients of 0.883, 0.760, and 0.868 were found for each of the three factors respectively. These coefficients indicated good internal consistency and were higher than those found in the original checklist analysis. An external validation was undertaken with the original food literacy behavior checklist, and a strong positive relationship between the two tools was found. In addition to being used to evaluate FSA, this revised and extensively validated tool could provide guidance to others evaluating similar food literacy programs and contribute to international measurement research.
