Is body mass index (BMI) relentlessly increasing in NZ, or plateauing?
In this blog we present trends in BMI by ethnicity in NZ going back to the 1980s. Over the last four decades the annual increase in BMI is linear, relentless increasing; no sign of a plateau, yet. Given this trend, The Diabesity Crisis symposium just held in Auckland, under the auspices of the Better Start and Healthier Lives National Science Challenges and Edgar Diabetes and Obesity Research seems aptly named. What are the forthcoming research and policy priorities?

“It is too dangerous.” This is the reason given most commonly for not riding a bike on the road in New Zealand. In this blog, I summarise a paper we have just published quantifying the risk of cycling injury. We found it to be low compared to other activites that New Zealanders commonly engage in. For example, riding a bike to a rugby game is roughly 500 times safer than playing the game. I conclude by examining why cycling is so marginalised (the bike is shunted, literally, to the side of the road), and how this might be changed.

Our recently published study on sudden mass fatality events in NZ (10+ deaths per event) found that the occurrence and mortality burden of these events has declined over time. In this blog we consider possible reasons for this trend and make suggestions for improving the knowledge base around these events.
