Sustained Resilience: the impact of nuclear war on New Zealand and how to mitigate catastrophe

Dr Matt Boyd & Prof Nick Wilson* (Syndicated from the Adapt Research Blog)

Efforts to prevent nuclear war should be greatly intensified – but we must also consider what happens if prevention fails. NZ is often cited as somewhere most likely to preserve a thriving society through a nuclear aftermath. However, our society is a complex adaptive system heavily dependent on trade. Major perturbations triggered by nuclear war could shift the state of NZ society from one of flourishing to one of mere survival. We detail these risks of societal failure and conclude with a set of first steps NZ could take to strengthen its societal systems.

In this blog we explore the first Covid-19 Omicron variant waves in Australia and Aotearoa New Zealand (NZ). We find that Australia’s first Omicron wave resulted in higher hospitalisation and ICU occupancy compared to NZ. However, when examining the Auckland region compared with the rest of NZ, Auckland’s experience of the first Omicron wave is more severe, with a higher hospitalisation rate. We recommend that the NZ Government does more to prepare for a possible second Omicron wave (as in Australia) and for future variants of concern. Priority areas are increasing vaccination coverage and improving mask use and indoor ventilation.

Poor diet is a major risk factor for excess weight gain and obesity-related diseases, including cardiovascular diseases, type 2 diabetes mellitus, osteoarthritis, and multiple cancers. In this blog we summarise our recent modelling work that suggests that the implementation of taxes on unhealthy foods and beverages in Aotearoa New Zealand (NZ) will lead to health gains, health system cost-savings, and reductions in health inequalities.

Smoking denormalization and tobacco endgames

Thursday, March 24th, 2022 | carra86p | No Comments

Janet Hoek, Richard Edwards, Andrew Waa*

Once a common practice, smoking prevalence has declined since its peak in the 1960s, after the serious health risks it poses became clear. Government policies and social marketing campaigns have progressively reduced smoking’s acceptability; however, slow reductions in prevalence have seen inequities persist and led some governments to adopt tobacco endgame strategies that rapidly reduce smoking prevalence by a specific date. Achieving endgame goals will bring profound health benefits but face opposition. Tobacco companies have simultaneously opposed core endgame measures, attempted to metamorphose into public health allies, and tried to shape social norms by framing smoking is a personal choice. In this blog, we expand on research exploring smoking’s trajectory and declining social acceptability, and consider challenges that tobacco endgame strategists will need to address.

Long COVID: a crucial reason for vax, mask, and distance

Tuesday, March 22nd, 2022 | carra86p | 1 Comment

Prof John D. Potter*

Long COVID occurs in at least 20-30% of individuals who have been infected with SARS-CoV-2 and is strongly related to the severity of the initial illness. There are insufficient data to provide a trajectory or a timeline for duration and resolution. The downstream damage can affect: brain, heart, lungs, pancreatic beta cells (resulting in diabetes), muscles, the immune system, eyes, kidneys, and erectile tissue. There is, to date, quite consistent evidence that vaccination is wholly or partly protective against long COVID, whether vaccination occurs before or after COVID-19. A society wanting to minimise the health and cost burden of managing long COVID would therefore choose to maximise vaccination coverage as well as minimise risk of infection with standard public health and social measures.
