Engaging New Parents in the Development of a Peer Nutrition Education Model Using Participatory Action Research

School-based healthy eating interventions for adolescents aged 10-19 years: an umbrella review

BACKGROUND

The benefits of healthy eating are well known, yet adolescent diet is often poor. School based interventions offer a promising option to promote healthy eating, however, evidence is unclear.

AIM

This umbrella review synthesised the current evidence on school-based interventions for healthy eating in adolescents (10-19 years old).

METHODS

Using Joanna Briggs Institute (JBI) umbrella review guidelines, a systematic search was conducted on 11 electronic databases (PubMed, CINHAL, EMBASE, Science Direct, PsycINFO, MEDLINE, Scopus, ERIC, Web of Science, Cochrane Register of Systemic Review and JBI Evidence Synthesis) to identify reviews published between January 2000 and December 2023. Methodological quality was assessed using JBI critical appraisal tool. A narrative synthesis was conducted informed by the World Health Organisation's Health Promoting School (HPS) framework that categorises school-based interventions into three components i.e., health education, school environment changes, and family and community involvement.

RESULTS

Seventeen reviews were identified (including 347 unique primary studies) that were published between 2008 and 2023. 87% of the reviews were based on interventions in high- income countries, limiting applicability to low- and middle-income countries. Fourteen reviews were rated as high, two as moderate, and one was rated as low methodological quality. Evidence from 71% of the reviews (n = 14 reviews, 13 = high methodological quality) found that multi-component interventions (i.e., interventions incorporating more than two components of the HPS framework) improved adolescents' knowledge and behaviour concerning healthy eating. At the individual level, tech-driven healthy eating curricula effectively improved eating behaviours of adolescents. These individual-level interventions proved to be more effective and sustainable when supported by system-level changes, such as modifying school environments including increased availability of healthy foods and involving parents to promote healthy eating for adolescents. However, limited evidence from only three reviews suggests mixed feasibility for technology-based interventions and lower feasibility for multi-component interventions. The lack of information on stakeholder involvement in intervention design is another critical evidence gap.

CONCLUSION

School-based multi-component healthy eating interventions that combine individual-level interventions with system-level changes are effective in promoting healthy eating behaviours among adolescents. Future reviews should assess the effectiveness of participatory approaches in intervention design, feasibility and scale-up studies, and analysing evidence from low- and middle-income countries.

Perceptions of food environments in the school and at home during Covid-19: An online cross-sectional study of parents, teachers and experts from Latin America

BACKGROUND

The high prevalence of overweight and obesity in children from Latin America (LA) have been related to obesogenic food environments. Besides, the negative effects of the Covid-19 pandemic should also be considered. The objective of this research was to describe and compare the perceptions of parents, teachers, and experts in LA of food environments at home and school that favor healthy habits in schoolchildren in pre Covid-19 stage and during the pandemic.

METHODS

This study used a survey self-reporting regarding conditions at home and the school favoring healthy habits, for three profiles: parents, primary school teachers, and experts. A fisher exact test was used to establish the difference between the response categories between countries and profiles. Logistic regression models were used to determine the probability of response in the levels of importance adjusted for sex and nationality.

RESULTS

Information from 954 questionnaires was reported: 48.4% experts, 32.0% teachers, and 19.6% parents. There were differences in the perception of food environments at school between profiles (p<0.001). In multivariate logistic regression models, experts and teachers were 20% more likely to give greater importance to elements of the food environment at school compared to parents (p<0.001).

CONCLUSIONS

Our findings showed that parents were less likely to perceive important elements of the school food environment compared to experts and teachers. Interventions are required to improve healthy eating environments that consider children's interpersonal mediators.

Online reach and engagement of a child nutrition peer-education program (PICNIC): insights from social media and web analytics

BACKGROUND

Parents frequently seek parental advice online and on social media; thus, these channels should be better utilized in child health interventions. The Parents in Child Nutrition Informing Community (PICNIC) program aims to facilitate peer-to-peer sharing of evidence-based child feeding information and support parents within their social networks. The present study aimed to explore web and social media analytics to evaluate reach and user engagement with the PICNIC online components.

METHODS

Online user activity data from the PICNIC Facebook closed group and public Page were collected through Facebook Insights, and program-specific website traffic data through Google Analytics. Analytics data from Nov-2019 to April-2021 was evaluated through visualisation and summary statistics to obtain insights into program growth and current reach in Australia, compare demographics of audience reached through the online channels, and explore parents' use and engagement in PICNIC content.

RESULTS

Results showed steady program growth in the 18 months of recruitment; participant numbers grew from 102 to 261 peer educators while the Facebook Page audience increased threefold, totalling 1615 followers. Intervention posts shared on Facebook (4-5 posts/week) typically reached only a portion of PICNIC Page followers each week, but also reached a wider audience through their friends. Throughout the evaluated period, Facebook users actively engaged in PICNIC posts, although the level of engagement varied considerably from post to post. Furthermore, results from this study suggest the strategy of directing potentially interested parents from social media to the website for program sign-up was successful. Finally, the explored data gave insights into users' availability, demographics and engagement, which will be used to inform refinement of the PICNIC website and social media strategies.

CONCLUSIONS

Our findings confirm the benefits of using a peer education approach and existing social network channels to disseminate evidence-based child feeding information to parents. This study also demonstrates the usefulness of web and social media analytics to be used as part of a continuous evaluation for gaining insight to inform further development and improvement of program strategies.
