Real-time recording
Today, children are exposed to an unprecedented amount of marketing for high-fat, sugar and salt (HFSS) foods and non-alcoholic beverages. Exposure to HFSS products influences children's food preferences and consumption patterns. As children increasingly live, learn and play online, understanding their exposure to food and food marketing in digital environments has become a growing area of research. Real-time recording of children's devices offer…
Child’s-eye views of smartphone-based gaming content
Children’s engagement with smartphone-based (online) gaming content is rapidly increasing. There appears to be no existing objective evidence of children’s exposure to this content captured in real time. Evidence on preteens’ smartphone-based gaming is especially scarce. This study aimed to objectively explore the nature and extent of preteens’ exposure to smartphone-based gaming content. Sixty-six children aged 11–13 years from 16 schools in the…
Clearing the haze
Marketing of tobacco and vape products is effective at recruiting new users; yet, little is known about children’s online exposure to such material. This research aimed to develop a methodology for assessing children’s exposure to, and engagement with, online tobacco and vape marketing. This pilot study used data from the innovative Kids Online Aotearoa Study in which 156 11–13-year-olds from schools in the Wellington region of Aotearoa New Zeala…
Public health and harmful advertising
The consumption of unhealthy commodities (UHCs) - including unhealthy food, alcohol, tobacco and gambling products - contributes to substantial public health harm and significant social and economic costs. Consumption of UHCs is driven, in part, by increasingly sophisticated, persuasive and extensive product marketing. In Aotearoa New Zealand (NZ), UHC marketing is largely self-regulated by industry but varies by individual commodity. This paper …
Generating political priority for alcohol policy reform
Comparison of ten policy options to equitably reduce children’s exposure to unhealthy food marketing
Objective: Reducing children’s exposure to unhealthy food marketing is crucial to combat childhood obesity. We aimed to estimate the reduction of children’s exposure to food marketing under different policy scenarios and assess exposure differences by socio-economic status. Design: Data on children’s exposure to unhealthy food marketing were compiled from a previous cross-sectional study in which children ( n 168) wore wearable cameras and Global…

Ensuring the right to food for indigenous children
The right to food for indigenous children, is linked to political and economic systems that are an outcome of colonisation. A decolonising approach where Māori voices and values are central within NZ policies and policy-making processes is needed. Given the importance of food to health, a broad policy approach from the NZ government to ensure the right to adequate food is urgent. This includes economic policies to end child poverty and specific s…
Equity of expenditure changes associated with a sweetened-beverage tax in Tonga
The sweetened-beverage tax was associated with reduced soft drink purchasing and increased bottled water expenditure. Low-income households appeared to have slightly greater declines in soft drink expenditure
Impact of sugar-sweetened beverage taxes on price, import and sale volumes in an island
Objective: To evaluate the impact of changes in import tariffs on sweetened beverages. Design: Interrupted time series analysis was used to examine sweetened beverage tariff increases of 40–60 % in 2008 and to 75 % in 2012, and an approximately 11 % decrease in 2014 when an excise tax replaced the tariff. Post-tax trends were compared with a counterfactual modelled on the pre-tax trend for: quarterly price of an indicator beverage, monthly bevera…
Rights-Based Approaches to Improving Food Availability for Tamariki Māori

The Politics of Health Promotion
Health promotion is inherently political. Not only is it largely funded by government, but the very nature of the enterprise requires shifts in power. Political theory has much to contribute to an understanding of the politics of health promotion. In this paper three key political theories are explained and their insights for health promotion explored. They are then applied to the development of a National Drug Policy in New Zealand. The theories…
Patterns of sports sponsorship by gambling, alcohol and food companies
This study found that the sponsorship of popular sports for young people is dominated by "unhealthy" sponsorship (ie, predominantly gambling, alcohol and unhealthy food) relative to "healthy" sponsorship. Governments may need to consider regulations that limit unhealthy sponsorship and/or adopt alternative funding mechanisms for supporting popular sports
Tackling health inequalities
Government and sector leadership were critical to the success of the workshops and subsequent changes in policy and practice. The use of locally adapted equity tools, requiring participants to develop action plans, and using a case study to focus discussion were important to the success for the training. Using institutional theory was helpful in analysing how drivers of inequalities, such as racism, are built into health institutions. This New Ze…
Perceptions of New Zealand nutrition labels by Māori, Pacific and low-income shoppers
Background In New Zealand the burden of nutrition-related disease is greatest among Māori, Pacific and low-income peoples. Nutrition labels have the potential to promote healthy food choices and eating behaviours. To date, there has been a noticeable lack of research among indigenous peoples, ethnic minorities and low-income populations regarding their perceptions, use and understanding of nutrition labels. Our aim was to evaluate perceptions of …
Global influences on milk purchasing in New Zealand – implications for health and inequalities
BACKGROUND: Economic changes and policy reforms, consistent with economic globalization, in New Zealand in the mid-1980s, combined with the recent global demand for dairy products, particularly from countries undergoing a 'nutrition transition', have created an environment where a proportion of the New Zealand population is now experiencing financial difficulty purchasing milk. This situation has the potential to adversely affect health. DISCUSSI…

Measuring Blue Space Visibility and ‘Blue Recreation’ in the Everyday Lives of Children in a Capital City
Blue spaces (water bodies) may promote positive mental and physical health through opportunities for relaxation, recreation, and social connections. However, we know little about the nature and extent of everyday exposure to blue spaces, particularly in settings outside the home or among children, nor whether exposure varies by individual or household characteristics. Wearable cameras offer a novel, reliable method for blue space exposure measure…
Housing as a Determinant of Tongan Children’s Health
