Finding new way to control blood pressure receives $5m funding boost

Half the New Zealanders being treated for blood pressure don’t have it under control, according to a University of Auckland researcher who has been awarded nearly $5 million from the Health Research Council of New Zealand (HRC) to look at the problem from a completely different angle.

Professor Julian Paton says we urgently need a new way to control high blood pressure – a condition affecting one-third of adult New Zealanders and disproportionately more Māori and Pacific people.

His study is one of five research programmes funded as part of the HRC’s $81 million investment in new research projects and programmes announced today by Minister Megan Woods.

Professor Paton says despite the armoury of medications currently available, treated patients still remain at elevated risk of cardiovascular events such as stroke, heart attacks and blood-clotting.

The poor control rate reflects treatment resistance, drug intolerance and poor patient compliance due to the unpleasant side-effects of some medications. But it’s also due to current medications treating the symptoms, and not what Paton believes is a primary cause of high blood pressure.

“None of the frontline pills affect the activity that’s generated from the brain that goes to the heart and blood vessels” – an area that’s become a focal point for researchers in recent years.

Professor Paton says activity in the nerves to the heart and blood vessels – known as the sympathetic nerves – is substantially increased in people with high blood pressure.

“We know that their activity is raging – much higher than it should be – and we believe this is causing much of the squeezing down on the blood vessels, causing blood pressure to rise.”

Professor Paton’s research team believes controlling sympathetic activity is the key to controlling blood pressure, and the best way to do that could be by targeting a sensory organ that’s the size of a rice grain at the top of the neck, called the carotid body.

Dysfunctional activity in the carotid body has been found to activate the sympathetic nerves which in turn squeezes blood pressure up. But what exactly causes this abnormal activity will be the focus of Professor Paton’s research over the next five years.

Initial testing will be in rats and sheep to first establish the mechanisms involved and to decipher if a new drug candidate could switch off the problematic signals. Patients recruited from specialist clinics will also be tested to see if excessive carotid body activity causes severe levels of blood pressure.

By the end of this programme, researchers will know whether the carotid body is over-active in patients with high blood pressure – a critical first step before testing any new treatment on humans.

The Health Research Council’s acting chief executive, Dr Vernon Choy, says this research programme gives New Zealand a unique opportunity to identify the root cause of a problem affecting a billion people worldwide, and could pave the way for new treatments to be developed.

“High blood pressure is the biggest risk factor for cardiovascular disease – the leading cause of death globally – and it’s clear we don’t yet know everything about controlling it. This is research that could save lives, improve the quality of life in people with high blood pressure, and dramatically reduce hospital admissions.”

Baby food pouches come under the spotlight

They dominate the baby food section in supermarkets, but could baby food pouches be setting our babies up for future problems with obesity and dental cavities?

Squeezable baby food pouches with plastic spouts are described as a mess-free and easy food alternative for babies ‘on-the-go’, and they now have an extraordinary market share in New Zealand – a 2018 audit of one of New Zealand’s largest supermarket chains indicates that these pouches make up 70 per cent of baby foods available. However, despite their apparent widespread use, there has been virtually no published research done either in New Zealand or internationally on the possible impacts of these pouches on babies’ diets or health.

Associate Professor Anne-Louise Heath from the University of Otago has received a Project grant from the Health Research Council of New Zealand (HRC) to explore what babies are eating in New Zealand once they move from an exclusively milk diet to solid food.

This ‘First Foods NZ’ study will observe 625 babies aged between eight and nine months from Auckland and Dunedin, measuring their nutrient intake, particularly iron levels, and assess the impact of baby food pouches on babies’ growth and dental health.

“The food in baby food pouches is similar to that found in baby food jars and cans, but their delivery method has the potential to markedly change infant nutrition,” says Associate Professor Heath.

“Anecdotal reports suggest babies are often consuming the food straight from the pouch, unsupervised. These super smooth foods are very easy for babies to eat. A 120g pouch is the equivalent of about 22 teaspoons of food. It can take a lot of time to spoon-feed a baby that amount, whereas to squeeze out that amount from a pouch is much easier. We want to find out if pouches result in babies overeating because they’re so easy to eat, and if they are displacing more nutrient-rich foods such as breastmilk from the diet.”

The research team will also track the babies to see if the sweet and acidic foods commonly found in baby food pouches – even some vegetable-based varieties – are causing problems for babies’ erupting teeth.

“Manufacturers in New Zealand are generally super cautious about not adding sugar to baby foods, but natural fruit sugar is still sugar. When these baby foods are consumed by sucking on a pouch, the teeth are bathed in fruit sugars, and probably much more so than if they were to eat whole fruit or to be spoon-fed. This could increase the risk of tooth decay.”

A recent small randomised controlled trial1 suggests that even by seven months of age, 12 percent of New Zealand babies may already be consuming more than the World Health Organisation recommendation of less than five percent of energy intake from free sugars, including fruit purees.

“If you’re only giving your baby a pouch every now and again it will probably make no difference to your baby’s health, whereas if it’s a regular thing it may have risks – or it may have benefits, such as upping your baby’s fruit and vegetable intake. We have to keep an open mind with our research as we don’t know which way it will go.”

As part of the First Foods NZ study, Associate Professor Heath and co-principal investigator Professor Rachael Taylor will also assess the nutrition, health and safety impacts of another method of feeding that’s growing in popularity in New Zealand: baby-led weaning. This technique involves giving babies finger foods to feed themselves from about six months on, instead of parents spoon-feeding them pureed food and slowly progressing to more textured food as the Ministry of Health currently recommends.

Proponents of baby-led weaning see it as a healthier, more convenient, and less stressful way of feeding babies, however some health professionals have raised concerns about the potential increased risk of iron deficiency, slower weight gain, and choking.

HRC acting chief executive Dr Vernon Choy says all parents want to know what the safest and best way is to feed their babies.

“There is so little research on baby food pouches or baby-led weaning that the Ministry of Health is currently unable to advise parents on their use. This puts health professionals in a difficult position because they are forced to form an educated opinion based on little-to-no evidence. They then have to decide if they’re going to share that opinion or leave parents to perhaps seek out other sources like social media for advice,” says Dr Choy.

“This research will provide some much-needed evidence to help the Ministry of Health update their advice to Plunket and other Well-Child providers on whether, and how, parents should use these relatively new methods of baby feeding.”

The HRC has awarded $60.3 million in funding for 53 research projects, including Pacific health and Rangahau Maori projects. These grants form part of the HRC’s $81 million investment in new research projects and programmes announced today by Minister Megan Woods.

Supporting the mental health of Pacific ‘climate change migrants’

New Zealand could become a potential relocation destination for many Pacific peoples displaced from their homelands by rising sea levels and other climate-change related natural disasters.

Dr Jemaima Tiatia-Seath, co-head of the School of Māori Studies and Pacific Studies at the University of Auckland, has received a Pacific Project grant from the Health Research Council of New Zealand (HRC) to explore how New Zealand could ready its health system to best support the mental health needs of Pacific ‘climate change migrants’. Her study will involve research sites in New Zealand, Niue and the Cook Islands.

“Very few people in the Pacific region will be unaffected by climate change, particularly as half the population live within 1.5 kilometers of the ocean. Rapid rises in sea level, more severe cyclones and floods, and changes to seasonal weather are all occurring in the Pacific and are attributed to climate change,” says Dr Tiatia-Seath.

“Migration is an indirect impact of climate change. One estimate is that 75 million people from the Asia-Pacific region will be forced to migrate by 2050 because of it. Much of the health research done to date has largely focused on the physical health problems associated with climate change – the mental health impacts have only recently been recognised.”

Dr Tiatia-Seath says Pacific peoples forced to relocate will likely be at higher risk of negative mental health challenges due to the cultural loss and stress of climate-induced migration.

“An understanding of this issue in New Zealand’s mental health sector is vital. Mental health services will need to cater to Pacific climate change migrants in culturally-inclusive ways and recognise the new challenges that migration and forced relocation will bring to the already visible barriers to mental health access for Pacific peoples.”

HRC manager of Pacific research investment, Tolotea Lanumata, says this study is very timely as the New Zealand Government has made looking at the impacts of climate change a priority.
“Climate change is predicted to have a substantial negative effect on global mental health. This study gives New Zealand the chance to get on the front-foot and prepare our health system for the mental health challenges that climate change will likely have on Pacific communities,” says Ms Lanumata.

The HRC has awarded funding for four Pacific project grants worth a combined total of $2.37 million. These grants form part of the HRC’s $81 million investment in new research projects and programmes announced today by Minister Megan Woods.
Pacific Project grants support research that contributes to better health outcomes for Pacific peoples, families and communities. For a full list of the recipients, see below.
