Schoolchildren who are suspended, expelled or drop out early are more likely to suffer from poor health and social difficulties - or even die young, according to new research.
An Auckland District Health Board three-year review of youth mortality in Auckland has identified a high rate of school disengagement among people who die young.
It found that youngsters who do well at school had a better chance to grow up healthy and become successful but those who had dropped out were likely to take risks and were more likely to die.
In its 2008 to 2011 review of 70 non-medical deaths of young people aged between 10 and 24, the ADHB Child Youth Mortality Review group identified a high rate of school disengagement with those involved.
With education data available for 53 of these people, their research showed that 23 had been stood down from school at least once - with 11 per cent stood down twice or more.
Of the 53, 28 committed suicide, 12 died in road crashes, six drowned, four died in falls, two from alcohol poisoning and one died after inhaling butane.
Twelve had left or been excluded from school before their 16th birthday.
Starship Childrens Hospital acting director of child health Dr Mike Shepherd said the findings, presented at the Children in Crisis Conference in Hamilton yesterday, were tragic but not surprising. "They're a reinforcement of some existing knowledge so to that degree it really does emphasise the nature of this problem."
He said the ADHB was working with schools and primary health care organisations on a strategy that tries to identify at-risk children before their problems start, including having nurses at lower decile schools to screen for issues and helping children and their families.
"Our view is that we are trying to do stuff at the top of the cliff ... hopefully we are going to be able to identify these young people much earlier and keep them involved in school."
Child and Youth Mortality Review Committee chairman Dr Nick Baker said groups were working with police, CYF, the Ministry of Education and Transport, hospitals and schools to identify the levels of support needed.
He said there was a pattern across the country among youth who were experiencing "accumulating adversity" like being stood down, exposed to domestic violence or being in CYF care.
"Of course one of the things is that if you get stood down you're often in a home environment that hasn't nurtured you sufficiently to keep you out of trouble and you have less supportive influences so it's really no surprise that bad things happen."
Secondary Schools Principals Association president Tom Parsons said the number of exclusions, expulsions and stand-downs was declining and schools worked hard to retain their pupils but there were serious concerns for those who slip through the cracks.
"Where they go to from there is very problematic because there is no catcher out there and no safety net out there for those students so the next time they come into authority's view is in the courts or A and E and so on."
