Nutritional knowledge in an Italian population of children, pre-adolescents and adolescents

Nutrition-Related Knowledge and Nutrition-Related Practice among Polish Adolescents-A Cross-Sectional Study

The aim of this study was to examine the association between nutrition-related knowledge (NRK) and nutrition-related practice (NRP) among 1440 Polish students (aged 10-18 years) and identify the determining factors. Questions about NRK and NRP were thematically similar and referred to the recommendations of the Polish Pyramid of Healthy Nutrition and Lifestyle for Children and Adolescents (4-18 years). A cross-sectional study was conducted using the CAWI method. The respondents obtained an average of 51% of points in the NRK examination and 32% of points in the NRP examination. It was shown that NRP was positively associated with NRK (p < 0.001). The students' NRK was positively determined by the following factors: being female (p < 0.001), older age of students (p < 0.001), living in a larger town (p = 0.012) and a higher level of education of the mother/legal guardian (p < 0.001). NRP was positively associated with greater physical activity of the students (p < 0.001). NRK and NRP were negatively associated with the subjects' BMI (p = 0.029; p = 0.040, respectively). The analysis of NRK shows that the students' knowledge regarding the consumption of milk, milk products and fish should be increased (17-20% correct answers). The analysis of NRP reveals that only 4-14% of students declared appropriate eating habits regarding the consumption of sweet and salty snacks, fish, wholegrain products and milk. This study highlights the need for targeted educational strategies to increase both the understanding and application of dietary guidelines among Polish adolescents for the prevention of diet-related diseases.

Developing a knowledge, attitude, and practice questionnaire on nutrition, physical activity, and body image for 13-14-year-old female adolescents

Objectives

The objective of this study was to develop and validate a Knowledge, Attitude, and Practice Questionnaire (KAPQ) on nutrition, physical activity, and body image for 13-14-year-old female adolescents.

Method

The KAPQ initially consisted of 73 items, covering knowledge (30), attitude (22), and practice (21) related to nutrition, physical activity (PA), and body image (BI). The content and face validity were tested to identify the relevance of the questionnaire items to the content and their relevance to nutrition, PA, and BI. Construct validity was assessed using an exploratory factor analysis (EFA). Internal consistency was determined by Cronbach's α value, and stability was determined based on test-retest reliability.

Results

Based on the EFA, each scale had several dimensions. The Cronbach's α ranged between 0.977 and 0.888 for knowledge, 0.902 and 0.977 for attitude, and 0.949 and 0.950 for practice. The test-retest reliability revealed that the kappa of knowledge was 0.773-1.000, while the intraclass correlation (ICC) values for attitude and practice were 0.682-1.000 and 0.778-1.000, respectively.

Conclusion

The final KAPQ, which included 72 items, was valid and reliable for assessing the KAP levels for nutrition, PA, and BI of 13-14-year-old female students in KSA.

Validation of a General and Sports Nutrition Knowledge Questionnaire in Italian Early Adolescents

To the best of our knowledge, no specific questionnaires on sports nutrition knowledge (NK) have been validated so far in Italian early adolescents. The aim of the present study was to validate a short (26-item) general and sports NK questionnaire in a group of Italian early adolescents. To this aim, the questionnaire was administered to 264 subjects for analysis of internal consistency, and in a subgroup (n = 39) for evaluating the reliability over time. The questionnaire revealed good overall internal consistency and reliability (Cronbach’s α = 0.684) and a highly significant correlation over time (r = 0.977, p < 0.001). Comparison with other validated questionnaires is tricky, because the previous questionnaires were validated in different populations, such as middle or late adolescents or adults, with a higher number of items compared to our questionnaire. Furthermore, data on adolescent NK in Italy are very limited. This study provides a brief, feasible, and validated questionnaire that can be used for investigating sports NK in young subjects. It could be used for evaluating the efficacy of education on general and sports nutrition in both the general population and athletes, and for investigating the relationship between NK and different sports in early adolescence.

"Do you think adolescents' food intake is satisfactory?" - Views of Indian parents and teachers

Adolescents develop food habits that affect both their present and future health. Underpinned by the stakeholder theory, this study was designed to explore the perspective of parents and nutrition educators regarding urban Indian adolescents' food habits. Thirty-two educators and 280 parents from five independent, English-speaking, secondary schools in Kolkata, India completed a paper-based instrument consisting of both closed and open-ended measures. Qualitative data were subjected to thematic analysis informed by the Template Analysis Technique. Descriptive and cross-tabulation analyses were employed to assess quantitative data. Three quarters (75%) of the respondents were dissatisfied with the ubiquitous consumption of energy-dense, nutrient-poor foods and sugar-sweetened beverages as well as the low intakes of healthy foods like fruits and vegetables among urban Indian adolescents. Six reasons were advanced for such unhealthy consumption including i) Proliferation of fast food retail outlets; ii) Hyper-palatability of fast food; iii) Marketing of fast food on electronic and social media; iv) Diminished household cooking practices; v) Lack of food knowledge; vi) Tendency to seek peer group acceptance. Both parents and educators suggested some healthy eating strategies aimed at improving the food and nutrition situation in Indian secondary schools to foster healthy eating among pupils. These included: i) Restrictions on the sale of unhealthy foods in school canteens; ii) Increased availability of attractive and palatable nutritious foods; iii) Discussion of the advantages of consuming healthy foods and inclusion of food preparation techniques in the school curriculum; iv) Home Economics coursework to be made mandatory for students. The findings suggest that Indian parents and teachers are likely to support changes to the food and nutrition curricula and to school food provision to foster healthy eating among adolescents.

Validation of a nutrition knowledge questionnaire in Italian students attending the University of Parma

OBJECTIVE

The aim of this study was to assess the validity and reliability of a self-administered nutrition knowledge (NK) questionnaire for Italian university students.

DESIGN

The NK questionnaire included ninety questions on experts' nutritional recommendations, nutritional content of food, health aspects of food and diets, relationship between diet and diseases, and proper food choices. It was administered to the same population under the same conditions on two different occasions with a time interval of 3 weeks between the two administrations.

SETTING

The survey was carried out at the University of Parma (Italy) during the 2018-2019 academic year.

PARTICIPANTS

Data were collected for 132 bachelor and master degree students attending the University of Parma, either attending or not nutrition classes during their studies (19-30 years, 29·5 % males, 57·6 % with an academic nutrition background).

RESULTS

The questionnaire revealed high overall internal consistency reliability (Cronbach's α > 0·8) and a good temporal stability with high correlation of the total score (r = 0·835, P < 0·001). Moreover, it showed a good ability to discriminate between subjects with potentially different NK.

CONCLUSIONS

This NK questionnaire proved to be a reliable, valid and easy-to-use tool for assessing the NK of Italian university students, either with or without nutrition background.

Rango Cards, a digital game designed to promote a healthy diet: a randomized study protocol

BACKGROUND

Several food and nutrition education actions have been described in the literature, with emphasis on the recommended use of innovative methods when addressing a young audience. Digital games are an attractive, dynamic, and motivating resource for teaching and learning practices, and adolescents form the group that readily accepts and adopts new technologies. Adapting dietary and nutritional guidelines to change dietary behavior is a challenge, and game-based learning has several benefits that can be used in this sense. Thus, this study aims to outline a nutritional intervention for school-aged adolescents from the Federal District, Brazil, whose object is a digital card game aimed at promoting healthy dietary practices.

METHODS

In this randomized study with intervention and control groups, we propose a nutritional intervention for adolescents studying in Federal District private schools. The intervention group will be introduced to Rango Cards, a digital game specifically developed for this study. The purpose of the game is to present the concept of an adequate and healthy diet using simple information in a playful context. This game features cards for foods/meals, characters, and healthy habits. The players' choices may lead them to winning or losing. Theme selection and phase order were designed to provide a learning experience. The control group will not receive any material during the study. Both groups will complete questionnaires before and after the intervention. The game is expected to improve food knowledge and self-efficacy in the adoption of healthy practices, thus contributing to appropriate dietary consumption.

DISCUSSION

The game was designed as a food and nutrition education tool based on Brazilian dietary guidelines. We believe that Rango Cards will provide a comprehensive experience on the topic, improving the students' autonomy, motivation, and pleasure of learning.
