BACKGROUND/OBJECTIVES: Filipino children aged 6-10 yrs are consuming poor quantities and quality of food based on the 2013 Philippine National Nutrition Survey. During these years healthy eating habits must be formed through family influence. Within this background, a complete package of nutrition intervention-feeding and nutrition classes, was pilot tested in selected schools to determine 1) changes in nutrition attitude and behavior and 2) food intake of schoolchildren after the intervention. SUBJECTS/METHODS: A quasi-experimental design was used in the study. School children aged 7-9 yrs enrolled in selected Philippine public elementary schools and their mothers/caregivers were the study participants. Profile and socio-demographic data were collected from each participant at baseline. The nutrition behavior and food intake of children were determined using the modified Child and Diet Evaluation Tool (CADET) and the 24-h food recall form, respectively. Data were analyzed using Stata version 15. RESULTS: No significant differences in characteristics were found among the 339 child-mother pairs in the 4 study groups. The modified CADET recorded improved mean attitude scores of children ranging from 22 to 24 points at endline in the group receiving both lunch feeding and nutrition education classes (group 3). The perceived better behavior of children was reported by their mothers in terms of increased intake of milk and vegetables and decreased consumption of sugar. These improvements were supported by the actual food intake of children obtained from the 24-h food recall. CONCLUSIONS: Family involvement, particularly of mothers/caregivers, appeared to be an important factor in shaping the children's eating behavior. An intervention package with lunch feeding and nutrition classes resulted in a substantial improvement in children's behavior and actual food intake with increased levels of vegetables and milk while lowering sugar consumption. The adoption of the intervention package in public elementary schools should therefore be pursued.

Objectives: The purpose of this study was to examine the effects of the types of nutrition labeling on the processing fluency, health evaluation and purchase intentions of home meal replacements. Methods: This online experimental study was conducted from December 29 to 31, 2019 and included 134 participants. The research design was 2 (Objective nutrition labeling: present vs. absent) × 2 (Evaluative nutrition labeling: present vs. absent) and each participant was randomly assigned to one of four groups. As stimuli, five types of ready-to-heat foods sold in the market were used. Results: Processing fluency (4.91 points) and purchase intention (4.13 points) were significantly high when both evaluative nutrition labeling and objective nutrition labeling were presented, and healthfulness evaluation (4.47 points) was significantly high when only evaluative nutrition labeling was presented. All three variables were measured to be high when evaluative nutrition labeling was presented. The evaluative nutrition labeling that visually represented nutritional values was found to be more effective for processing fluency, healthfulness evaluation, and purchase intention than the objective nutrition labeling representing the nutritional value of the product in numbers and proportions. Conclusions: These results show that it is necessary to develop various types of evaluative nutrition labeling to enable consumers to choose and purchase healthful home meal replacements. Also, consumer education and public campaigns are needed to encourage consumers to select healthier home-cooked meals using nutrition labeling.

Good snack consumption behaviors are important among elementary students because snack provides additional energy and nutrients and because good dietary behaviors should be formed during early stages of life. This study investigated, among elementary school students, 1) snack consumption behaviors, 2) snack-related nutrition knowledge level, and 3) relationships between snack behaviors and snack-related nutrition knowledge. A convenience sample (N = 372), drawn from 5th and 6th graders of an elementary schools in Siheung-si, Gyeonggi-do, completed a pre-tested questionnaire. More than 85% of the participants snacked more than once per week. Most (77%) had their snacks at home. Fruit and fruit juice were the most frequently consumed and the most liked snack items. Taste was the most important in choosing a snack item closely followed by health/nutrition. Snack-related knowledge level was relatively high and the participants obtained their nutrition knowledge through mass media (30.4%) and family/friends (29.0%). Snack-related nutrition knowledge level and snack consumption behaviors showed positive relationships in various areas such as choosing more nutritious snack items and checking nutrition labels. Although this study was limited by its cross-sectional study design, these positive relationships suggest that better nutrition knowledge could result in better behaviors. Results of this study indicated that factual nutritional knowledge has been well transmitted to students. Therefore, future nutrition education on snacking could focus more on providing problem-solving and operational knowledge.

The purpose of this study was to investigate the sustainable practices of nutrition science teachers and dietitians working in school food service operations, and identify the social and psychological factors which affect the overall efficacy of the system. The research model was constructed based on the Extended Theory of Planned Behavior (ETPB) in order to analyze how individual motivation affects the sustainable practices of nutrition science teachers and dietitians. The data were collected through e-mail and postal mail from nutrition science teachers and dietitians all across Korea, and self-administered surveys were conducted. SPSS and AMOS programs were used for statistical analysis. First, the sustainable practices of nutrition science teachers and dietitians were analyzed in 6 different categories. Second, the significant pathways were 6 out of 9 in the ETPB model. Sustainable food service practices in school can contribute to the formation of more a sustainable culture, such as through the encouragement of more healthy eating habits, and higher level of environmental awareness and community awareness. The factors influencing these practices can be applied to the design of improvement programs aimed at increasing sustainable practices.

Failure of the functions involved in ingestion leads to, not only loss of enjoyment of eating, but also protein-energy malnutrition. Dysmasesis and difficulty of swallowing occurs in various diseases, but aging is a major cause. In the aging society, the proportion of elderly people with dysmasesis and difficulty of swallowing is expected to increase rapidly. Developing foods for the elderly that are easy to chew and swallow is thus required. This study was conducted to develop easily chewable and swallowable foods for the elderly who can crush foods and ingest with their own tongues, but occasionally have difficulty in drinking fluids such as water and tea. Various foods for the elderly with chewing and swallowing difficulties were used for sensory assessment. The sensory panel consisted of 10 dietitians (10 women) in nursing care facilities. The sensory optimal composite recipes were determined by central composite design (CCD). The sensory measurements were significantly different in saltiness (p<0.05), sweetness (p<0.05), and overall quality (p<0.05). The optimum formulation of stir fried anchovy calculated by numerical and graphical methods was 3.74 g of soy sauces and 30.17 g of oligo-saccharides. Stir fried anchovy had a moisture content, hardness and adhesiveness of 76.52%, 2.10, and -1.57, respectively.

BACKGROUND/OBJECTIVES: Curfew due to the coronavirus disease 2019 (COVID-19) pandemic could influence health behaviors in people, especially in children, who can easily acquire unhealthy eating habits. This study aimed to investigate the effect of COVID-19 on weight, health behaviors including eating habits, physical activity, and sedentary behavior in children aged 6-15 years in Saudi Arabia. SUBJECTS/METHODS: We conducted a cross-sectional online survey that included 280 children aged 6-15 years in Saudi Arabia during the COVID-19 curfew. The survey included questions on sociodemographic characteristics, anthropometric measures, and health behaviors including eating habits, physical activity, and sedentary behavior. RESULTS: We observed a significant difference in the body mass index before and after the COVID-19 pandemic (P < 0.001). Children significantly tended to skip breakfast, along with a decreased intake of dairy products and fast food (P < 0.001). Moreover, children were less physically active and significantly tended to be involved in leisure screen-based activities, including watching TV and use of computer/games (P < 0.001). CONCLUSIONS: This study provides evidence for the negative influences of the COVID-19 curfew on health behaviors, including eating habits, physical activity, and sedentary behavior in children in Saudi Arabia.

Iron is the required microelement supporting life and is the main component of hemoglobin. Thus iron has affinity with exercise capacity. Iron metabolism turbulence induced by exercise is one of causes of hematopoietic hypofunction. Results of the experiment showed that long-term treadmill exercise of progressive loading significantly decreased levels of erythrocyte indexes, serum iron, serum ferritin and significantly increased serum transferrin level. Nutrition supplement could significantly retard the variations, and Exercise +Nutrition group have higher levels of erythrocyte indexes, serum iron, serum ferritin and lower level of serum transferrin than Exercise group. The results indicated that nutrition supplement have function of prevent and cure on iron metabolism turbulence induced by exercise, furthermore significantly enhance hemoglobin level in rats.

Over the past two decades in the United States, social marketing has become an increasingly popular means of delivering nutrition education for the purpose of eliciting a specific behavior change. This manuscript defines social marketing via traditional marketing concepts and jargon, as well as through a communications strategy that can be used to guide message and campaign development. Research and evaluation strategies necessary to support the development and assessment of campaign promotions, is discussed. Four campaigns implemented in the United States, and one campaign implemented in Indonesia, are discussed in terms of the strategies presented. These campaigns illustrate how this educational technique and an array of assessment approaches have been applied to varied nutritional issues across diverse target audiences and settings. Practical recommendations, as well as discussion of issues regarding the advantages and disadvantages of using social marketing as an educational strategy, campaign sustainability, and philosophical considerations regarding the use of this educational approach, are addressed.

Objectives： A meta-analysis of the literatures was conducted to evaluate the cost-effectiveness of medical nutrition therapy by dietitians. Methods : The 30 studies were identified from a computerized search of published research on MEDLINE, Science-Direct and the PQD database until May, 2002 and a review of reference lists. The main search terms were“dietitian”,“dietary intervention”,“nutrition intervention”, “cost”,“cost-effectiveness”and“cost-benefit analysis”. The subgroup analysis was performed by publication year, study design, intervention provider, type of patient (in/out-patient) and type of cost (total cost/direct cost). Two reviewers independently selected trials for inclusion, assessed the quality and extracted the data. Results : The 30 studies were identified using the electric database search and bibliographies. The 17 trials were eligible for inclusion criteria, then the systematic review and a meta-analysis were conducted on effectiveness and cost-effectiveness of medical nutrition therapy. The quality of the studies was evaluated using the quality assessment tool for observational studies. The quality score was 0.515 $\pm$ 0.121 (range : 0.279-0.711, median : 0.466). The meta-analysis of 17 studies based on the random effect model showed that medical nutrition therapy was highly effective in treating the diseases (effect size 0.3092 : 95% confidence interval 0.2282-0.3303). The vote-counting method, one of meta-analysis methods, was applied to evaluate the cost-effectiveness of medical nutrition therapy conducted by dietitians. Two criteria (method 1, method 2) for voting were used. The calculated p-values for method 1 (more conservative method) and method 2 (less conservative method) were 0.1250 and 0.0106, respectively. Medical nutrition therapy by dietitians was significantly cost-effective in the method 2. Conclusion. This meta-analysis showed that the effectiveness of medical nutrition therapy was statistically significant in treating disease (effect size 0.3092), and that the cost-effectiveness of medical nutrition therapy was statistically significant in the method 2 (less conservative method) of vote counting.
