Barry's blurb

Welcome to the 9th newsletter from the EHI team. Our apologies for the communication hiatus since our last newsletter, but we have waited until we knew the outcome of our contract renewal. I am delighted to report that our contract with the Ministry of Health has been extended for another three years (see the link below to the press release).  On behalf of the EHI team, I would like to thank you for your enthusiastic support over the last three years, and we are looking forward to continuing our collaboration with you.

As you will read in this newsletter, we have been continuing our work on exciting projects and the development of various information products related to indicators of environmental health. Having created the national hub for EHIs, we are encouraging people and organisations to make use of the data and information we have provided. We are currently developing indicators for the new domain of vulnerable populations. 

As always, please don’t hesitate to contact us if you have any suggestions or comments related to our work.

Highlights from the EHI factsheets

Topic

Highlights

Second-hand smoke exposure in the home

  • About 45,000 children and 106,000 non-smokers were exposed to second-hand smoke in their home in 2012/13.

  • There has been a large drop in exposure to second-hand smoke in the home since 2006/07, for both children (9.6% to 5.0%) and non-smoking adults (7.5% to 3.7%).  

  • Higher rates of exposure were seen in children, Māori, and people living in more socioeconomically deprived areas.

Lead absorption notifications in New Zealand

  • In 2013, there were 81 lead notifications that occurred in occupational settings.

  • Ninety-nine lead notifications were from non-occupational settings, of which 13 were in children under 15 years.

  • Child lead notifications in 2013 were at their highest since 2003

  • For children, the main sources of lead exposure were lead fishing sinkers and lead-based paint.

Building Pacific Capacity and Capability in Public Health

Riz Firestone, a new member of the EHI team, is leading a series of professional e-learning short courses on Pacific public health.

These courses aim to provide a short, yet robust, approach for developing the capacity and capability of any professional (be they a community worker, doctor/nurse, health manager, or working in policy) – anyone working within a Pasifika health space could enrol for these courses.

The EHI team has started consulting with other Pacific agencies about developing future online short courses in areas relevant and common to the wider Pacific regions (e.g., One health, agricultural health and animal health).  We also welcome any group who is interested in participating in this partnership.

For more information about the short courses, please contact Barry (B.Borman@massey.ac.nz) or Riz  (R.T.Firestone@massey.ac.nz).

Pacific region’s serious health issues in the spotlight

At a recent meeting to address public health issues in the Pacific, Barry and Riz proposed creating a hub for environmental health indicators in the Pacific region, similar to the national hub we have built for New Zealand. We have already gained enthusiastic support from potential collaborators in a number of Pacific countries, and we very much look forward to progressing on this new initiative.

Whanganui Affordability Study

Caroline recently developed an economic profile of the Whanganui district, to measure the affordability to ratepayers of upgrading the district’s wastewater plant. The study used existing data to model the impact of a scaled series of rate increases on household expenditure. The study also identified vulnerable populations who would be least able to absorb the increased expenditure. Estimates of both the proportion of the population, and the number of people likely to be affected, were identified.

The Whanganui Affordability Study provided input on economic vulnerability into an overall project plan for upgrading key infrastructure.  It highlighted the amount of data out there which can be applied to local situations. The study was not exclusive to the wastewater project, but could be used in other areas of council planning and decision making.

Bowel Screening Pilot Interim Report now available

Deborah, Mathu and Barry carried out the epidemiological analysis for the evaluation of the Bowel Screening Pilot funded by the Ministry of Health.  The epidemiological interim report presented findings about participation and outcomes from the first 18 months in the four-year pilot (2012–2015).  Participants were aged 50–74 years and lived in the Waitemata District Health Board area, and the results took into account the effects of demographic factors including age, sex, ethnicity and deprivation.

After controlling for all other factors, the results for the first 18 months of the pilot showed that:

  • The overall participation rate was 53.5% (among people invited to take part), and the overall detection of adenoma (a non-cancerous tumour) was 3.4%, advanced adenoma was 1.9%, and cancer was 0.2%.
  • Participation increased with increasing age, and the detection rate of adenoma, advanced adenoma and cancer increased with increasing age.
  • Males were slightly less likely to participate than females. However, males were more likely to have an adenoma, advanced adenoma, or cancer detected than females.
  • Participation was particularly low among the Pacific people. Māori were more likely to have an advanced adenoma detected than Europeans, while Asians were less likely to have an advanced adenoma detected than Europeans.
  • Participation decreased with increasing deprivation. However, participants in the most deprived areas were more likely to have an adenoma or advanced adenoma detected than participants from the least deprived areas.

The complete results from Round One of the Bowel Screening Pilot are now available on the Ministry of Health’s website.

The full evaluation report of the four-year pilot will be completed in 2016.

Evaluation of the Healthy Families New Zealand Initiative

Healthy Families NZ aims to improve people’s health where they live, learn, work and play, in order to prevent chronic disease – by making good food choices, being physically active, sustaining a healthy weight, being smokefree and reducing alcohol-related harm. The initiative brings community leadership together, and challenges communities to think differently about the underlying causes of poor health, and to make changes – in schools, workplaces, sports clubs, marae and other key community settings – that will help people make healthier choices. 

Anna Matheson, together with Mat Walton and evaluators from the SHORE/Whariki Research Centre, are collaborating to evaluate this complex initiative.   The overall design of the evaluation is a comparative case study, which best suits that the initiative is being undertaken in 10 different geographic locations: East Cape, Far North, Invercargill City, Lower Hutt City, Rotorua District, Whanganui District, Manukau Ward, Manurewa-Papakura Ward, Spreydon-Heathcote Ward, and Waitakere Ward. The evaluation will seek to answer questions in three broad areas: what has been implemented; assessment of the quality of implementation; and what outcomes have been achieved and how. The Baseline data collection is currently underway.

Meetings and presentations

PHA Conference

The Public Health Association held its conference in a rather chilly Dunedin this year. It was well attended with over 400 delegates. The theme of the conference was “Healthy people, healthy nation – Public Health is everybody’s business” and was split into four strands:

  • Civic action for a civil society
  • Commerce and public health
  • Economics of wellbeing
  • Future of public health

Keynote speakers posed interesting and challenging questions, including how our cities can adapt to become more sustainable, and how we can address the growing problem of obesity.

Caroline gave presentations on two of these themes, with an overview of the CPHROnline website, and results of a cost-effectiveness analysis of community water fluoridation. Both topics were well received. The first sparked enquiries for further data to be displayed – for example on breastfeeding, as well as interest in using the website for data. The second, as always, sparked lively debate, and very positive debate on the expansion of community water fluoridation into new communities.

The New Zealand HealthWork Conference

Barry and Fei received very favourable responses from 80 delegates to their presentation of  the latest results from our occupational disease surveillance system at the New Zealand HealthWork Conference in Auckland on the 4 November. 

The conference, hosted by Thomson Reuters (publisher of Employment Today and Safeguard), aimed to challenge, inspire and expand people’s understanding of worker health and wellbeing.
