Is Youth Vaping a Problem in New Zealand? - Public Health Expert

Dec 02, 2019

Professors Janet Hoek and Richard Edwards, Emeritus Professor Phil Gendall, Jude Ball, Dr Judith McCool, Anaru Waa, Dr Becky Freeman Recent media reports have presented conflicting evidence on youth vaping in NZ. While some NZ school principals report concerns about increasing vaping on school grounds and confiscating vapes, ASH Year 10 survey data have been interpreted as suggesting few young people who are non-smokers are vaping. How can these apparently contradictory perceptions co-exist? In this blog, we begin by outlining recent findings on electronic nicotine delivery systems (ENDS) and their potential contribution to public health. We then explore possible explanations for why reports and perceptions about youth vaping sometimes differ and offer suggestions about how this behaviour needs to be more effectively monitored. ENDS’ impact on population health Electronic nicotine delivery systems (ENDS) deliver nicotine to smokers using a … Read More

New Zealand’s Poor Pandemic Preparedness According to the Global Health Security Index - Public Health Expert

Nov 11, 2019

Dr Matt Boyd, Prof Michael Baker, Prof Nick Wilson The Global Health Security Index which considers pandemic threats has just been published. Unfortunately, NZ scores approximately half marks (54/100), coming in 35th in the world rankings – far behind Australia. This poor result suggests that the NZ Government needs to act promptly to upgrade the country’s defences against pandemic threats. The Global Health Security Index (GHSI) The GHSI is the first ‘comprehensive assessment and benchmarking of health security and related capabilities across the 195 countries that make up the States Parties to the International Health Regulations’ [1]. The philosophy behind the index is that all countries must not only prioritise capabilities to prevent, detect and rapidly respond to public health emergencies, but that countries must also have a robust health system, be compliant with international norms, and work to improve … Read More

Retailing of vaping products – New NZ Research - Public Health Expert

Nov 07, 2019

Dr Lindsay Robertson, Dr Jerram Bateman, Professor Janet Hoek Members of the public health community hold divergent views on how access to vaping products or electronic nicotine delivery systems (ENDS) products should be arranged. Some believe ENDS should be as widely available as smoked tobacco and argue for liberal access. However, others suggest smoked tobacco should be much less available than is currently the case and propose that only retailers skilled in supporting smoking cessation should sell ENDS. In this blog, we probe concerns about allowing widespread availability of ENDS and related products. We first draw on related research into smoked tobacco products and then discuss findings from our recently published study that questions the wisdom of allowing ENDS to be sold by non-specialist retailers. Proposed ENDS regulation The Associate Minister of Health responsible for tobacco has announced that, … Read More

“Action for Healthy Waterways”: Some big ticket actions that the Government has neglected - Public Health Expert

Oct 31, 2019

Prof Nick Wilson, A/Prof George Thomson, A/Prof Simon Hales, Prof Michael Baker The NZ Ministry for the Environment has produced a valuable discussion document with many good ideas for improving the health of waterways in New Zealand. But there are important gaps. In this blog we consider three big-ticket items to include in an integrated strategy to improve our waterways: a fertiliser tax, taxing ruminant animal products, and promoting the right sort of reforestation with a high carbon price. Introduction As we recently pointed out, the health of waterways has important health and cultural impacts for people in Aotearoa/NZ [1]. Fortunately, the Ministry for the Environment (MfE) has produced a detailed discussion document [2], which has many good ideas around protecting and improving the health of NZ’s waterways. In particular, the overarching concept of Te Mana o te Wai, … Read More

Protecting Fresh Waterways in Aotearoa/NZ: The Strong Public Health Case - Public Health Expert

Oct 17, 2019

Nick Wilson, Leah Grout, Mereana Wilson, Anja Mizdrak, Phil Shoemack, Michael Baker Protecting waterways has the benefits of: (1) protecting water from hazardous microbes; (2) minimising cancer risk and other problems from nitrates in water; (3) avoiding algal blooms that are hazardous to health; (4) protecting mahinga kai uses (cultural importance and food security); (5) facilitating safe recreational water use; (6) minimising flooding risks from silted up waterways; and (7) protecting renewable energy from waterway sediments. In this blog we briefly consider these issues and why health workers and agencies should now do submissions on protecting waterways to the Ministry for the Environment, as part of a current consultation process which ends on 31 October.   Introduction  The NZ Ministry for the Environment (MfE) has recently published a discussion document, titled “Action for healthy waterways” [1]. As part of developing … Read More

Not forgetting the benefits to youth and non-smokers – an example from increases in tobacco taxes - Public Health Expert

Sep 09, 2019

Prof Nick Wilson, Prof Richard Edwards, Prof Janet Hoek Tobacco control’s focus on supporting smokers to quit, thus reducing the harm they face (e.g., via appropriately regulated access to e-cigarettes) remains important. However, we need to do more to protect youth and non-smokers from the burden of tobacco. In this blog we use the issue of tobacco tax increases to show the potentially large benefits to youth and non-smokers – as well as to smokers who quit. Policy-makers need to take a broad view of how tobacco control policies impact on society so that progress to the country’s Smokefree 2025 goal is accelerated. Introduction Debates about which interventions and policies to implement to reduce smoking prevalence often focus on the potential impacts (positive or negative) on smokers. This is understandable as it is smokers who suffer most immediately from … Read More

Meat, Health, Hospitals, and Sustainability - Public Health Expert

Aug 26, 2019

Prof John Potter Achieving healthier diets that are also sustainable is increasingly in the news. In this blog, I look at the case for reducing the amount of meat in hospital meals and gently remind our dietitian colleagues not to let their dietary advice get out of date. Over-consumption of meat is costing us. Our health, our healthcare system, and our environment are all in a state of crisis. This was summarised in the recent Ministry of Health report Sustainability and the health sector [1], championed by Associate Health Minister, the Hon Julie Anne Genter. It was good to hear Dietitians NZ, in their response, emphasising the value of prevention, particularly with an eye to reducing admissions to hospital. However, their reaction to the Minister’s specific recommendation that the health system should reduce meat and dairy consumption was concerning. They … Read More

What can we learn from Healthy Housing Initiatives? New evidence from the Wellington Well Homes scheme - Public Health Expert

Jul 17, 2019

Elinor Chisholm, Nevil Pierse, Cheryl Davies, Philippa Howden-Chapman We know that poor housing conditions result in ill health for many New Zealanders, and we know which interventions are required to ensure good quality housing that supports health. Healthy Housing Initiatives intervene to improve the homes of kids who are hospitalised for illnesses that could be related to poor housing conditions. In this blog post, we draw on recently published research to gain insights about housing and health, and explore views about the effectiveness of these Ministry of Health-funded programmes. There is overwhelming evidence that living in poor quality housing is devastating to health and that improving housing conditions can promote good health.  New Zealand research has shown how low indoor temperatures and mould impair children’s lung function (1,2), that almost 28,000 hospitalisations per year are for diseases potentially … Read More

How should we manage the harm caused by tobacco product waste? - Public Health Expert

Jun 14, 2019

Professor Janet Hoek and Emeritus Professor Philip Gendall Annual consumption of cigarettes now exceeds five trillion, with around four trillion butts littered every year. These cigarette butts cause major environmental damage and impose significant clean-up costs on local authorities. Although tobacco companies have framed smokers as responsible for butt litter, recent debate has focused on the tobacco industry’s role in creating tobacco product waste (TPW) and its responsibility for managing this problem.  We recently examined public perceptions of TPW in New Zealand and allocation of responsibility for creating and managing it. Cigarette filters were first introduced in the 1950s and 60s, in response to growing evidence that smoking caused lung cancer and other serious (and often fatal) illnesses. Advertising at the time declared filtered cigarettes were “Better for your health” and sought to reassure smokers that switching to a … Read More

Lessons from Canada for NZ: Carbon, Cycling, Tobacco, Nutrition and Cannabis - Public Health Expert

Apr 08, 2019

Prof Nick Wilson, Dr Amanda Jones, A/Prof George Thomson Canada has a number of progressive public policies which can influence health. In this blog we briefly look at 6 potential lessons for NZ in the domains of: (i) responding to climate change; (ii) supporting cycling; (iii) tobacco control; (iv) controls on food marketing directed at children; (v) healthy food guidelines; and (vi) cannabis law reform. Canada is a high-income country that has some cultural, legal and organisational similarities to New Zealand (NZ). Canada’s current government is also relatively progressive on various health and social issues. For these reasons, the Canadian policy experience may be relevant to NZ and be worth studying. Here we look at six stand-out areas of potential public health significance for NZ. 1) Response to climate change There is international survey data to suggest … Read More
