•Support was found for the knowledge-is-power position relating to food label use.•Most studies focused on nutrition labels, few included claims and ingredient lists.•Nutrition knowledge supported ...food label use across a range of knowledge measures.•More research with representative samples and wider age ranges is needed.
Nutrition information on food labels is an important source of nutrition information but is typically underutilized by consumers. This review examined whether consumer nutrition knowledge is important for communication of nutrition information through labels on packaged foods. A cognitive processing model posits that consumers with prior knowledge are more likely to use label information effectively, that is, focus on salient information, understand information, and make healthful decisions based on this information. Consistent with this model, the review found that nutrition knowledge provides support for food label use. However, nutrition knowledge measures varied widely in terms of the dimensions they included and the extensiveness of the assessment. Relatively few studies investigated knowledge effects on the use of ingredient lists and claims, compared to nutrition facts labels. We also found an overreliance on convenience samples relying on younger adults, limiting our understanding of how knowledge supports food label use in later life. Future research should 1) investigate which dimensions, or forms, of nutrition knowledge are most critical to food label use and dietary decision making and 2) determine whether increases in nutrition knowledge can promote great use of nutrition information on food labels.
The impact of providing nutrition education on the nutritional knowledge of young athletes in IndonesiaBackground: A lack of nutritional knowledge can lead to poor eating habits and nutritional ...deficiencies in young athletes. One of the issues leading to athletes' need for more knowledge is the absence of professional assistance in educating them about nutrition. Objective: This research was analyzed to investigate the impact of nutrition education through counseling and group-based nutrition education on the nutritional knowledge of young athletes in Indonesia. Methods: This study is a pre-and post-experimental study without control. One hundred eighty-five young athletes who trained in PPLP and SKO received nutrition intervention for two months, including three nutrition education sessions using sports nutrition module media, nutritional counseling, and eating assistance based on eating etiquette. A modified Abridged Nutrition for Sport Knowledge Questionnaire (ANSKQ) questionnaire assessed athletes' nutritional knowledge before and after the intervention. Data was examined by comparing scores before and after the intervention. The Kolmogorov-Smirnov test was used in the normality test, and a paired t-test was used to compare nutritional knowledge before and after the intervention. Results: Before the intervention, 88.65% had a low level of knowledge about nutrition. The scores for sports nutrition and overall nutritional knowledge increased significantly (p<0.05). The scores of general nutrition knowledge increased but were not significant (p>0.05). Conclusions: There was a significant increase in sports nutrition knowledge but not general nutrition knowledge. The provision of nutritional education assisted by nutritionists impacts athletes' nutritional knowledge.
Background: Sports nutrition knowledge is one of the essential needs of coaches. However, there is no standardized questionnaire in Persian to assess coaches' nutritional knowledge and information. ...Therefore, the purpose of this study is to evaluate the validity and reliability of Persian version of the Coach Sports Nutrition Questionnaire (CSNQ). Methods: CSNQ was translated-re-translated according to the WHO standard method, following Iranian culture and eating habits. The reliability of the questionnaire was assessed by test-retest method, correlation coefficient and internal reliability by Cronbach's alpha, and differential validity by independent t-test. 123 Iranian coaches completed the questionnaire. Results: The total internal reliability of the questionnaire assessed by Cronbach's alpha was 0.73. The intragroup correlation of the questionnaire, assessed by the test-retest method, was 0.71. Moreover, the comparison of the coaches with different levels of education was found to be significant (P < 0.001). Conclusion: The Persian version of the questionnaire regarding the coaches' nutrition sports knowledge has acceptable reliability and validity. It can help other studies and evaluate sports nutrition knowledge in Persian coaches.
To investigate whether food literacy competencies and diet quality vary between 16-to-24-year-olds vegans, lacto-ovo vegetarians, pescatarians, flexitarians and omnivores and to assess whether food ...literacy is associated with diet quality.
Cross-sectional study. Food literacy (general nutrition knowledge, critical nutrition literacy and food skills) and diet quality were measured using an electronic questionnaire.
Southern Norway, September 2021 - March 2022.
Healthy 16-24-year-olds (
165).
Overall, the mean general nutrition knowledge score was moderate (48·0 out of 67·0); the lowest mean score was found in omnivores and the highest in flexitarians (45·6
. 51·5) (
= 0·034). The mean score of critical nutrition literacy was also moderate (3·7 out of 5·0); vegans showed higher scores compared to other dietary practices (
= 0·018). No difference was observed in food skills between the different dietary practices. The overall median diet quality score was 46·0 out of 80·0, lowest in omnivores and highest in vegans (42·0
. 56·0) (
=< 0·001). In multivariate regression analyses, general nutrition knowledge, food skills and vegan dietary practice were significantly associated with higher diet quality.
We found moderate levels of food literacy across all dietary practices. The food literacy competencies, general nutrition knowledge and food skills were associated with higher diet quality in our sample. Omnivores showed both the lowest general nutrition knowledge level and lowest diet quality scores. In contrast, both flexitarians and vegans scored highest on general nutrition knowledge and diet quality scores, despite being one of the less restrictive and one of the strictest plant-based dietary practices, respectively.
Introduction: The role of nutrition and eating disorders in physical health, and body image in mental health is very important. Therefore, the purpose of this research was investigating the ...relationship between nutritional knowledge and eating disorders with body image in athletic and non-athletic students of the Islamic Azad University of Ahvaz. Materials and Methods: This study was applied research and employed a descriptive-correlation design, which was carried out in Ahvaz city in 2022. Data collection tool included two questionnaires namely eating disorders and body image designed by Stick et al. and Parmenter and Wardell's nutritional knowledge questionnaire. The athlete community was around 300 people and the number of non-athlete community was around 18000 people. According to Morgan's table, 377 non-athlete students and 169 athletes were selected randomly and by available sampling, respectively. The tests used in this research were Spearman's correlation coefficient and May-Whitney's test, which were performed through SPSS 22 software. Results: The results showed that there was a negative and significant relationship between nutritional knowledge and body image in athletic and non-athletic students, and there was a positive and significant relationship between eating disorders and body image (p<0.05). Conclusion: The result showed that exercise can be effective in eating disorders and nutritional knowledge. Therefore, by improving sports facilities or motivating students to engage in sports activities, it would be possible to provide the basis for improving students’ nutritional knowledge as well as eating disorders.
The present systematic review examined the relationship between nutrition knowledge and dietary intake in adults (mean age ≥ 18 years). Relevant databases were searched from the earliest record until ...November 2012. Search terms included: nutrition; diet or food knowledge and energy intake; feeding behaviour; diet; eating; nutrient or food intake or consumption. Included studies were original research articles that used instruments providing quantitative assessment of both nutrition knowledge and dietary intake and their statistical association. The initial search netted 1,193,393 potentially relevant articles, of which twenty-nine were eligible for inclusion. Most of them were conducted in community populations (n 22) with fewer (n 7) in athletic populations. Due to the heterogeneity of methods used to assess nutrition knowledge and dietary intake, a meta-analysis was not possible. The majority of the studies (65·5%: community 63·6%; athletic 71·4%) reported significant, positive, but weak (r< 0·5) associations between higher nutrition knowledge and dietary intake, most often a higher intake of fruit and vegetables. However, study quality ranged widely and participant representation from lower socio-economic status was limited, with most participants being tertiary educated and female. Well-designed studies using validated methodologies are needed to clarify the relationship between nutrition knowledge and dietary intake. Diet quality scores or indices that aim to evaluate compliance to dietary guidelines may be particularly valuable for assessing the relationship between nutrition knowledge and dietary intake. Nutrition knowledge is an integral component of health literacy and as low health literacy is associated with poor health outcomes, contemporary, high-quality research is needed to inform community nutrition education and public health policy.
In an effort to address undernutrition among women and children in rural areas of low‐income countries, nutrition‐sensitive agriculture (NSA) and behaviour change communication (BCC) projects heavily ...focus on women as an entry point to effect nutritional outcomes. There is limited evidence on the role of men's contribution in improving household diets. In this Agriculture to Nutrition trial (Clinicaltrials.gov identifier: NCT03152227), we explored associations between men's and women's nutritional knowledge on households', children's and women's dietary diversity. At the midline evaluation conducted in July 2017, FAO's nutrition knowledge questionnaire was administered to male and female partners in 1396 households. There was a high degree of agreement (88%) on knowledge about exclusive breastfeeding between parents; however, only 56–66% of the households had agreement when comparing knowledge of dietary sources of vitamin A or iron. Factor analysis of knowledge dimensions resulted in identifying two domains, namely, ‘dietary’ and ‘vitamin’ knowledge. Dietary knowledge had a larger effect on women's and children's dietary diversities than vitamin knowledge. Men's dietary knowledge had strong positive associations with households' dietary diversity scores (0.24, P value = 0.001), children's dietary diversity (0.19, P value = 0.008) and women's dietary diversity (0.18, P value < 0.001). Distance to markets and men's education levels modified the effects of nutrition knowledge on dietary diversity. While previous NSA and BCC interventions predominantly focused on uptake among women, there is a large gap and strong potential for men’s engagement in improving household nutrition. Interventions that expand the role of men in NSA may synergistically improve household nutrition outcomes.
Reliable and valid assessment of sports nutrition knowledge can inform athlete nutrition education to address knowledge gaps. This study aimed to test the reliability and validity of an ...electronically administered sports nutrition knowledge tool - Platform to Evaluate Athlete Knowledge of Sports Nutrition Questionnaire (PEAKS-NQ). A 94-item PEAKS-NQ was piloted to 149 developmental athletes (DA) in New Zealand, with a subset invited to complete the PEAKS-NQ again to assess reliability. Reliability was evaluated using sign test, intraclass correlation and Cronbach's α. Accredited sports dietitians (ASD; n 255) completed the PEAKS-NQ to establish construct validity via known-groups methodology and provided relevance scores to determine the scale content validity index (S-CVI). Rasch analysis was conducted to identify potentially problematic items and test reliability. Score differences between DA and ASD were analysed using independent t or non-parametric tests. DA (n 88) were 17·8 (sd 1·4) years, 61·4 % female and mostly in high school (94·3 %). ASD (n 45) were 37·8 (sd 7·6) years, 82·2 % female, with >5 years of dietetic experience (59·1 %). ASD scored higher than DA in all sections and overall (91·5 (sd 3·4) v. 67·1 (sd 10·5) %) (P < 0·001). There were no differences between retests (n 18; P = 0·14). Cronbach's α was 0·86. S-CVI indicated good content validity (0·88). Rasch analysis resulted in a fifty-item PEAKS-NQ with high item (0·91) and person (0·92) reliability. The PEAKS-NQ is reliable and valid for assessing sports nutrition knowledge which could assist practitioners effectively tailor and evaluate nutrition education.
