Everyone knows that socio-economic inequalities in health exist – in recent times. But one thing we do not know is whether they have always been there. We have just published a study that looks at two historical datasets – with one of these suggesting life span differences by occupational class as measured 100 years ago. We find strong differences in life expectancy by occupational class among men enlisted to fight in the First World War (but not actually getting to the frontline). Whilst not definitive evidence (it is hard to get perfect evidence from 100 years ago!), it does suggest that socio-economic inequalities in mortality have existed for at least 100 years in NZ. In this blog we also take the opportunity to discuss what might be done to address the current inequality problem in this country.

This blog was triggered by the recent highly publicised review on the cancer risk from processed meat and red meat. Here we briefly look at this topic and also take a wider perspective on other aspects of meat consumption on human health and the environment, and risk communication.

In this blog we review the latest update by the Ministry of Health on how much of NZers life expectancy can be expected to be in good health. The good news? We are both living longer, and living longer in good health. The bad news? According to this report, the percentage of our lives with some dependency due to poor health is increasing. And there are marked inequalities in healthy life expectancy. This sort of analysis, as hard as it is to get right, is important – as a society we do not want to just live longer, but live longer in good health. However, we have concerns about the accuracy of this Report, and critique it in this blog.

SNZ predictions of number of New Zealanders aged 65 plus
Have you sat in a meeting recently, or listened to the radio, where someone is invoking the aging population as a harbringer of doom and gloom due to the tsunami of older people with poor health? A tsunami that will overload health and social services, etc. Have you then asked yourself “Hang on a minute, if people are living longer are they not also healthier?”. Or even “Why on earth do government agencies and some academics keep talking about the number of people aged greater than 65 as a marker of some dependency on the state?”. Well, this Blog is for you. We use a paper just published in PLoS ONE that demonstrates how with falling mortality rates, population aging may actually slow due to a rapid increase in the age at which your remaining life expectancy is 15 years or less. And we draw on analyses from our own book, The Healthy Country? A History of Life and Death in New Zealand, to critique naïve assumptions about population aging. Which begs many questions, such as “Why is the age of entitlement for New Zealand superannuation still 65?” Read on.

This blog post looks at a recently published study of the lifespan of NZ soldiers who participated in the First World War. It then asks more broadly what is known about the longer term health outcomes for military personnel participating in war – and suggests that such issues need to be considered carefully by governments before participating in foreign military engagements.
