A school-based nutrition education program involving children and their guardians in Japan: facilitation of guardian-child communication and reduction of nutrition knowledge disparity

ABSTRACT:

Background

Since the risk of noncommunicable diseases is closely associated with dietary intake, it is important to establish healthy dietary habits in childhood. Although several dietary education programs for children have been attempted, their implementation at school was often difficult due to overcrowded study curricula. We developed a new program which included homework for children and guardians, and evaluated its effect. Determinants of the effect were also investigated.

Methods

The school-based nutrition education program including a 45-min lecture, a series of homework assignments involving children and guardians, and two handouts was implemented in 14 public primary schools in Japan. Seven schools each underwent the intervention in an alternating manner. Nutrition knowledge (percentage (%) of correct answers in the nutrition knowledge questionnaire) and attitude/behavior toward diet was evaluated three times (May (baseline), October, February) as outcomes. These factors and their changes following the intervention were assessed by linear mixed models to adjust for individual factors, with consideration to clustering of the participants and repeated measurements.

Results

In total, 2227 children aged 10–12 years and their guardians participated. All schools completed the program. Children’s nutrition knowledge level was significantly increased (8.7%, 95% confidence interval [7.7–9.7]) following the intervention. Communication between children and their guardians, which was positively related with nutrition knowledge, was facilitated by the intervention. The increase in nutrition knowledge was greater among children with a lower knowledge level at baseline.

Conclusions

This school-based nutrition education program was effective and feasible. Appropriate teaching materials for homework can reduce the burden on schools and facilitate communication between children and guardians. Public schools can be crucial venues for decreasing disparities in nutrition knowledge.

Project description:IntroductionNutrition literacy has been cited as a crucial life skill. Nutrition education as a primary school subject has been treated inconsequentially when compared to other subjects. We investigated an aspect of the current state of nutrition education in Ghana by engaging stakeholders about their sources of nutrition information and the perceived barriers in implementing nutrition education in mainstream primary schools.MethodsThree hundred and fifty one (351) primary school children, 121 homebased caregivers, six schoolteachers, two headteachers, two Ghana Education Service (GES) officials, and six school cooks were involved in the study. Surveys were used to collect data on nutrition information acquisition behaviors and to record perceived barriers. Key Informant Interviews were conducted among GES officials, headteachers, schoolteachers and school cooks, while Focus Group Discussions were used among homebased caregivers and children to gather qualitative information.ResultsOnly 36.3% of the primary school children had heard about nutrition, and 71% of those got nutrition information from their family members. About 70% of homebased caregivers had heard or seen nutrition messages, and their source of nutrition information was predominantly traditional media. Schoolteachers mostly received their nutrition information from non-governmental organizations and the Internet, while most of the school cooks stated their main source of nutrition information was hospital visits. Perceived barriers included schoolteachers' knowledge insufficiency, and lack of resources to adequately deliver nutrition education. Lack of a clear policy appeared to be an additional barrier.ConclusionThe barriers to the implementation of nutrition education in the mainstream curriculum at the primary school level that were identified in this study can be resolved by: providing schoolteachers with learning opportunities and adequate nutrition education resources for practical delivery, having specific national policy framework, and including family members and school cooks in the nutrition education knowledge and information dissemination process.

Project description:While many types of genetically modified (GM) food have become more available worldwide, the acceptance of GM food continues to be low. To increase this acceptance, various educational interventions have been conducted; however, conflicts remain about the safety and acceptability of GM food among laypeople, experts, and policymakers in several countries. Thus, this study aimed to clarify whether basic biology education influences Japanese people’s acceptance of GM food. We examined this idea by comparing individual experiences of high school biology education based on curriculum and proficiency level. We distributed online questionnaires to 1,594 people in Japan; 1,122 valid responses (70.4%) were obtained. Results showed that the acceptance rates of GM vegetables, fish, and meat were 33.6%, 29.0%, and 29.1%, respectively. Comparing the biology knowledge test scores according to different high school biology education levels (i.e., non-learners, basic, and advanced levels) showed no significant differences between the three age groups (20s, 30s, and 40s), which corresponded to different curricula (p = 0.90); however, there were significant differences between the high school biology education levels (p<0.01). Using logistic regression analysis, we then examined the effect of high school biology education on acceptance of GM food. The results showed no significant differences between different high school biology education levels but significantly lower acceptance by the 30s and 40s groups compared with the 20s group (p<0.05). This suggests that basic biology education alone is not sufficient to change people’s attitudes toward GM foods. These generational differences suggest factors other than high school biology curriculum affect different generations’ acceptance of GM foods. Overall, high school biology education did not directly affect acceptance of GM foods, although those who received a higher level of education had an increased knowledge of GM foods.
