Promoting healthy school food environments and nutrition in Canada: a systematic review of interventions, policies, and programs

CONTEXT

The school food environment is a critical interface for child and adolescent nutrition, and there is a need to understand existing literature on Canadian school food environments to identify equity gaps and opportunities, and empower decision-makers to plan for future action.

OBJECTIVE

Literature on Canadian school food and nutrition interventions, policies, programs, and their effects on diets and nutritional status are synthesized and appraised in this systematic review.

DATA SOURCES

A search strategy was developed for each database used (Medline, Embase, PsycINFO, ERIC, Cochrane Collaboration, Canadian Electronic Library, BiblioMap), with a combination of free text and controlled vocabulary, for articles published from 1990 to 2021. Unpublished data and grey literature were also searched.

DATA EXTRACTION

Quantitative and qualitative studies with an observational or intervention study design, reviews, or program evaluations conducted in Canadian schools with participants aged 5-19.9 years were included. Key study characteristics and risk of bias were extracted independently by 2 investigators using a standardized tool.

DATA ANALYSIS

A total of 298 articles were included (n = 192 peer reviewed and 106 from the grey literature), which were mostly conducted in Ontario (n = 52), British Columbia (n = 43), and Nova Scotia (n = 28). Twenty-four interventions, 5 nonevaluated programs, and 1 policy involved Indigenous populations. Overall, 86 articles measured and reported on effectiveness outcomes, including dietary intake; anthropometry; knowledge, attitudes, and practices; and physical activity. The literature remains largely heterogenous and primarily focused on nutrition education programs that use subjective assessments to infer changes in nutrition. A key facilitator to implementation and sustainability was community engagement, whereas key barriers were staff capacity, access to resources and funding, and consistent leadership.

CONCLUSIONS

This review provides insight into Canadian school food and nutrition interventions, programs, and policies and uncovers important evidence gaps that require careful examination for future evaluations. Governments must create supportive environments that optimize nutrition for children and adolescents through equitable policies and programs.

[Brazilian government proposals for actions to prevent and control overweight and obesity from a local perspective]

The article analyzes actions in the prevention and control of overweight and obesity that have been developed in the 92 municipalities (counties) in the state of Rio de Janeiro, Brazil, based on underlying principles in the typology of public policies developed by Lowi and Line of Care for Overweight and Obesity, according to the following analytical dimensions: program actions in prevention and control of obesity, characterization of macro policies according to the Lowi typology, and characterization of macro policies according to the Line of Care for Overweight and Obesity. The study is part of a research project from 2014 to 2018 that aimed to identify the strategies and challenges in the consolidation of the actions planned in the Line of Care for Overweight and Obesity, based on analysis of secondary data and government documents; searches in the municipalities' official websites; interviews; focus groups; and online questionnaires with health professionals and managers. The documents point to a series of actions such as individual consultations, support groups, health gyms, school health programs, and others, reinforced by the interviewees' narratives. Even with so many initiatives, the municipalities in the state of Rio de Janeiro face challenges with limited human resources and precarious infrastructure and equipment in the health units. To achieve mobilization in the actions to deal with obesity, the issue should be addressed specifically on the state and local agendas and not diluted among other activities and programs.

Trends in marketing foods to children in Slovenian magazines: a content analysis

OBJECTIVE

Food marketing is an important factor influencing children's food preferences. In Slovenia the use of magazines is widespread among children. We investigated food advertising in children's and teens' magazines (CTM) in 2013 and 2017. The penetration of food advertising was compared with magazines targeting the adult population.

DESIGN

A repeated cross-sectional study. Magazines were searched for branded food references (BFR). All BFR were categorised and evaluated using the WHO Europe nutrient profile model.

SETTING

Slovenia.

SUBJECTS

All issues of CTM and a selected sample of issues of adult-targeting magazines and newspapers published in Slovenia in 2013 and 2017.

RESULTS

One hundred and seventy-five issues of CTM (ninety-two in 2013, eighty-three in 2017) and 675 issues of adult-targeted magazines and newspapers were analysed (345 in 2013, 330 in 2017). In 2017, food advertising in CTM dropped notably but the opposite was found for adult-targeted magazines. Regular advertisements dominated in 2017 in CTM, while in 2013, 83 % of BFR types were games/puzzles, competitions and product placements. Chocolate and confectionery were the most advertised in CTM and food supplements in adults' magazines. Most foods in CTM were classed as 'not permitted' in both years (98 % in 2013 and 100 % in 2017).

CONCLUSIONS

The advertisements in CTM still mostly refer to unhealthy foods. The extent of food advertising has dropped considerably since 2013. On the contrary, food advertising in printed media targeting adults has increased, chiefly referring to food supplements and foods that do not pass the WHO Europe nutrient profile model criteria.
