The Tyee has published my latest article: A New Study Ties Lifespans to Wealth Gaps in Greater Vancouver. Excerpt:
We like to think of Greater Vancouver as one of the best places to live in Canada, if not in the world. Yes, it is — especially for those of us living in the most affluent neighbourhoods. Those in the poorest neighbourhoods, however, are dying younger than their rich neighbours, sometimes by many years. And the gap between them was getting wider even before the opioid-overdose crisis and the COVID-19 pandemic became twin health emergencies.
That’s an easy conclusion to draw from a recent study published in the journal Health & Place. Of course it’s more complicated than that, but it still seems paradoxical that a region as prosperous as Greater Vancouver should see some people die years younger than others living just a few kilometres away.
The study involved UBC researchers working with the Institute for Health Metrics and Evaluation at the University of Washington and with Imperial College, London. Its ambitious goal was to track life expectancy and major causes of deaths in Greater Vancouver over a quarter-century, from 1990 to 2016. Moreover, they broke the numbers down to the census-tract-level — in effect, neighbourhood by neighbourhood. Overall, the study offers an invaluable portrait of our collective health before the pandemic.
In some ways, it’s a very flattering portrait. Even the poorest males, in the tenth percentile, had a median life expectancy in 2016 of 77.6; that is, half died before that age and half later. For tenth-percentile females, median life expectancy was 82.5.
But in the 95th percentile, the richest five per cent of our population, median male life expectancy was 87.1. For females in the 90th percentile, it was 90.8. The poor were paying with almost a decade of their lives for the privilege of living here.
The study makes a striking observation: “Between 1991 and 2016, there was a downward trend in the LE [life expectancy] gap, whereby the lowest gap was observed in 2001 (6.9 years for females and 7.9 for males), but this reversed and increased by 1.4-1.6 years between 2001 and 2016.” By a wild coincidence, 2001 was the year the BC Liberals won a huge majority over the NDP and ran the province under Gordon Campbell and then Christy Clark until 2017.
British researchers noticed a very similar effect during Margaret Thatcher’s years in power: Around 1980, British and Japanese life expectancy were about the same, but then, as the U.K. income gap widened, British lives grew shorter. In Japan, with a much narrower income gap, life expectancy rose to among the highest on the planet.
What we’re dying of
And what have Greater Vancouver residents been dying of? Between 1990 and 2016, deaths from cardiovascular diseases, neoplasms (cancers) and unintentional injuries dropped sharply. Clearly, we’ve been exercising more, smoking less, and taking care of ourselves, at least up to a point.
But we’ve also seen a 10 per cent increase in neurological disorders, a catch-all term that can include everything from Alzheimer’s to eating disorders to meningitis. Other noncommunicable diseases like diabetes mellitus and kidney disease rose by almost four per cent.
And while the richest of us had little to fear from infectious diseases in 1991, the poorest were already contending with (and dying from) HIV-AIDS and sexually transmitted infections at 12 times the rate as the richest. The poorest faced seven times the rate of maternal and neonatal disorders. They died of neoplasms at over four times the rate of the richest.
