Latest research highlights the link between poverty and respiratory disease
The connection between poverty and respiratory disease is well established. Poverty affects respiratory health in many
ways with overcrowding and cold, damp houses known to cause respiratory illnesses and admissions to hospital. Poor
access to health care can often prevent these illnesses from being treated adequately.
The latest research by Dr Michael Baker and his colleagues from University of Otago, Wellington demonstrates the impact
that increasing social inequalities are having on respiratory disease.* The research shows that New Zealand hospital admissions for serious infectious disease have increased since the late
1980s and respiratory infections are the single biggest cause.
These nasty infections don’t affect all of us equally – they show strong links with poverty and huge inequalities
between ethnic groups with Maori and Pacific being particularly badly affected, and the gaps are widening. Once again,
these gaps reflect the increasing income inequalities in our country. There is little doubt that a large part of this
problem is caused by social and economic disadvantage. In recent years, income inequalities have risen faster in New Zealand than in most OECD countries.
“Serious infections cause great personal, social and financial costs for patients and families. They are also expensive
for the health service to treat,” says Bob Hancox, Medical Director of the Foundation. “We can, and should, do so much
more to stem this rise in infectious diseases. These diseases are fuelled by the inequalities in our society and we
urgently need to tackle these. Reducing poverty, better housing, and improving access to primary health care would be
good places to start.”
Asthma Foundation Chief Executive, Angela Francis believes that the time is now to take action. “Some people may ask
whether we can afford to do these things in tough economic times; the real question is, how can we not?”

2. New Zealand has the second highest rate of asthma in the world, following the UK.
3. About 800 000 New Zealanders are affected by asthma and other respiratory conditions.
