Objective: This study aimed to estimate the prevalence of vegetarians, vegans and other dietary patterns that exclude some animal-source foods in New Zealand adults. We also examined socio-demographic and lifestyle correlates of these dietary patterns. Design: The New Zealand Health Survey is a representative rolling cross-sectional survey of New Zealanders; data from the 2018/19 and 2019/20 waves were used for this analysis. Participants were asked if they completely excluded red meat, poultry, fish/shellfish, eggs or dairy products from their diet. Setting: New Zealand. Participants: Adults, aged ≥ 15 years (n 23 292). Results: The prevalence of red-meat excluders (2·89 %), pescatarians (1·40 %), vegetarians (2·04 %) and vegans (0·74 %) was low. After adjustment for socio-demographic and lifestyle factors, women (OR = 1·54, 95 % CI: 1·22, 1·95), Asian people (OR = 2·56, 95 % CI: 1·96, 4·45), people with tertiary education (OR = 1·71, 95 % CI: 1·18, 2·48) and physically active people (OR = 1·36, 95 % CI: 1·04, 1·76) were more likely to be vegetarian/vegan. Those aged ≥ 75 years (OR = 0·28, 95 % CI: 0·14, 0·53) and current smokers (OR = 0·42, 95 % CI: 0·23, 0·76) were less likely to be vegetarian/vegan. Similar associations were seen between socio-demographic and lifestyle factors and the odds of being a red-meat excluder/pescatarian. Conclusions: Approximately 93 % of New Zealand adults eat red meat and a very small number exclude all animal products from their diets. The Eating and Activity Guidelines for New Zealand adults recommend a plant-based diet with moderate amounts of animal-source foods. A comprehensive national nutrition survey would provide detailed information on the amount of red meat and other animal-source foods that the New Zealand population currently consumes.

The affordability of diets modelled on the current (less healthy) diet compared to a healthy diet based on Dietary Guidelines was calculated for population groups in New Zealand. Diets using common foods were developed for a household of four for the total population, Māori and Pacific groups. Māori and Pacific nutrition expert panels ensured the diets were appropriate. Each current (less healthy) diet was based on eating patterns identified from national nutrition surveys. Food prices were collected from retail outlets. Only the current diets contained alcohol, takeaways and discretionary foods. The modelled healthy diet was cheaper than the current diet for the total population (3.5% difference) and Pacific households (4.5% difference) and similar in cost for Māori households (0.57% difference). When the diets were equivalent in energy, the healthy diet was more expensive than the current diet for all population groups (by 8.5% to 15.6%). For households on the minimum wage, the diets required 27% to 34% of household income, and if receiving income support, required 41–52% of household income. Expert panels were invaluable in guiding the process for specific populations. Both the modelled healthy and current diets are unaffordable for some households as a considerable portion of income was required to purchase either diet. Policies are required to improve food security by lowering the cost of healthy food or improving household income.

Context: Many countries and institutions have adopted policies to promote healthier food and drink availability in various settings, including public sector workplaces. Objective: The objective of this review was to systematically synthesize evidence on barriers and facilitators to implementation of and compliance with healthy food and drink policies aimed at the general adult population in public sector workplaces. Data Sources: Nine scientific databases, 9 grey literature sources, and government websites in key English-speaking countries along with reference lists. Data Extraction: All identified records (N = 8559) were assessed for eligibility. Studies reporting on barriers and facilitators were included irrespective of study design and methods used but were excluded if they were published before 2000 or in a non-English language. Data Analysis: Forty-one studies were eligible for inclusion, mainly from Australia, the United States, and Canada. The most common workplace settings were healthcare facilities, sports and recreation centers, and government agencies. Interviews and surveys were the predominant methods of data collection. Methodological aspects were assessed with the Critical Appraisal Skills Program Qualitative Studies Checklist. Generally, there was poor reporting of data collection and analysis methods. Thematic synthesis identified 4 themes: (1) a ratified policy as the foundation of a successful implementation plan; (2) food providers’ acceptance of implementation is rooted in positive stakeholder relationships, recognizing opportunities, and taking ownership; (3) creating customer demand for healthier options may relieve tension between policy objectives and business goals; and (4) food supply may limit the ability of food providers to implement the policy. Conclusions: Findings suggest that although vendors encounter challenges, there are also factors that support healthy food and drink policy implementation in public sector workplaces. Understanding barriers and facilitators to successful policy implementation will significantly benefit stakeholders interested or engaging in healthy food and drink policy development and implementation.

Objective: To test the feasibility of a browser extension to estimate the exposure of adolescents to (un)healthy food and beverage advertisements on Facebook and the persuasive techniques used to market these foods and beverages.Design: A Chrome browser extension (AdHealth) was developed to automatically collect advertisements seen by participants on their personal Facebook accounts. Information was extracted and sent to a web server by parsing the Document Object Model tree representation of Facebook web pages. Key information retrieved included the advertisement type seen and duration of each ad sighting. The WHO-Europe Nutrient Profile Model was used to classify the healthiness of products advertised as permitted (healthy) or not permitted (unhealthy) to be advertised to children.Setting: Auckland, New Zealand.Participants: Thirty-four Facebook users aged 16–18 years.Results: The browser extension retrieved 4973 advertisements from thirty-four participants, of which 204 (4 %) were food-related, accounting for 1·1 % of the exposure duration. Of those food advertisements, 98 % were classified as not permitted, and 33·7 and 31·9 %, respectively, of those featured promotional characters or premium offers. The mean rate of exposure to not permitted food was 4·8 (sd = 2·5) advertisements per hour spent on Facebook.Conclusions: Using a Chrome extension to monitor exposure to unhealthy food and beverage advertisements showed that the vast majority of advertisements were for unhealthy products, despite numerous challenges to implementation. Further efforts are needed to develop tools for use across other social media platforms and mobile devices, and policies to protect young people from digital food advertising.

New Zealand has the second highest overweight and obese child population in the Organisation for Economic Co-operation and Development (OECD). This paper evaluates whether New Zealand’s self-regulatory controls on the advertising of unhealthy food and beverages to children and young people adequately protects children from the exposure to, and power of, such marketing in order to limit its impact on children’s food and beverage preferences. First, an analysis of the relevant New Zealand Advertising Standards Authority (ASA) Codes was conducted, including the ASA Complaints Board and Appeals Board decisions from 2017–2019 to determine the application of the Codes in practice. Second, a public health law framework was applied to the self-regulatory system. Of the 16 complaints assessed, 12 were not upheld, and only one was upheld under the Children and Young People’s Advertising Code (CYPA Code). Three complaints were upheld under the Advertising Standards Code (ASC) but not the CYPA Code. An analysis of the Codes and their interpretation by the Complaints Board found that many facets of the public health law framework were not met. The self-regulatory system does not adequately protect children from the exposure to, and power of, unhealthy food and beverage marketing, and government-led, comprehensive, and enforceable marketing restrictions are required.
