Drinking too much water probably killed bushwalker, coroner declares

A 30-YEAR-OLD Victorian man who died while bushwalking in North-West Tasmania last year most likely died from excessive consumption of water, a coroner has found.

The findings have come with a strong warning about the dangers of drinking too much water while exercising, and calls for better education about how much water the human body can safely take in.

Coroner Michael Brett said that Jonathan Paul Dent died on or about April 19 last year while bushwalking in the Dial Ranges, near Devonport.

In handing down his findings, Mr Brett said Mr Dent had most likely died from exercise-related hyponatremia, ''which itself resulted from excessive consumption of water during the course of the prolonged exertion of the bushwalk''.

After an initial autopsy failed to determine Mr Dent's cause of death, Mr Brett arranged for the evidence to be reviewed by Professor Anthony Bell, whose report noted that the autopsy showed a swollen brain with signs of herniation, which was consistent with excess water consumption.

According to Mr Brett, Mr Dent had set out for a bushwalk alone about 9.30am on April 19 from Wings Wildlife Park with the intention of following the track to Foggs Flat, a walk of about four hours.

Mr Brett said Mr Dent appeared to be in good health and was well equipped for the walk - he carried a mobile phone and was appropriately dressed for the conditions.

During the course of the day, Mr Dent's wife, Katherine, had several telephone calls from him indicating that he was lost but was still hopeful of making his way to a planned meeting spot with her later in the day.

By about 4pm he called his wife saying he was tired and dehydrated.

Further conversations indicated that he was lying down and his breathing was heavy and he was coughing, Mr Brett said.

By 8.25pm, Mrs Dent reported to Ulverstone Police that her husband was missing.

Mr Dent's body was found at 1.10pm the next day on a track just north of Foggs Flats.

Mr Brett said the case highlighted two specific concerns, including a general perception, particularly among people involved in athletic activities, ''that one should drink as much as possible and avoid becoming dehydrated during prolonged strenuous exercise''.

He said that there was a need for greater education in relation to the danger associated with excessive consumption of fluid during exercise.

Mr Brett also highlighted the issue of bushwalking alone.

''Had Mr Dent been in company, whilst it cannot be said that he would not have suffered the condition that led to his death, I suspect that he would have been in a substantially better condition to cope with the disorientation and fear that arose from being lost,'' he said.

People who grow up in countryside 'twice as likely to develop Alzheimer's'

Researchers from Edinburgh University found that people who were born and brought up in rural areas were at greater risk of the condition than those from towns and cities.

Although the cause of the trend is unclear, the scientists suggested factors like access to health care, or exposure to certain substances in either the countryside or in cities, could have played a role.

Alzheimer's, a form of dementia, affects more than 800,000 in Britain and the number of sufferers is expected to double by 2050 due to the ageing population.

The researchers studied 51 academic papers containing data on the medical records of 12,580 people from around the world, published over several decades.

The countries studied included the UK, USA and Canada as well as less developed nations like Nigeria and Peru.

Rates of dementia as a whole did not differ greatly between rural and urban dwellers, but for Alzheimer's specifically there was a marked difference, according to the results published in the International Journal of Epidemiology.

Dr Tom Russ, who led the study, emphasised the difference between the two groups could be down to benefits associated with living with cities, rather than harmful factors linked to the countryside.

He said: "We don't really know the mechanism. It could be to do with access to health care, exposure to some unknown substance, socioeconomic factors, or a number of other factors. We're currently looking into this question in more detail."

A priority for researchers will be to identify what causes the difference, so that more can be done earlier in life to prevent people developing the incurable condition, he added.

Dr Simon Ridley, of Alzheimer’s Research UK, said: “This data review observes a link between rural living and increased Alzheimer’s incidence and prevalence, but the complicated evidence is insufficient to prompt an exodus to the city.

"We should remember this is an amalgamation of global data that may not hold true for the UK. Big questions remain over whether particular exposures in early rural life or duration of rural living are at play."

Alcohol industry grooming children to drink by marketing booze-flavoured snacks, AMA claims

THE alcohol industry is grooming children to drink by marketing booze-flavoured chips, chocolates, lip gloss and biscuits.

The nation's peak medical organisation, the Australian Medical Association, wants new laws to restrict alcohol advertising aimed at young people after exposing the shocking tactics.

A 60 page report by the AMA, obtained by News Limited, uncovers how the alcohol industry is using online games that feature alcohol brands, secret parties with online invitations and Facebook to market alcohol to young people.

The report is to be released at a conference in Canberra on Wednesday amid a continuing national debate about alcohol and violence spearheaded by News Ltd's Real Heroes Walk Away campaign.

The AMA report says alcohol-sponsored mobile phone apps that provide cocktail recipes, conversation topics or use geolocation technology to recommend nearby bars and clubs are aimed at the young.

The industry has also encouraged children to develop a taste for alcohol by marketing Tim Tams flavoured with Tia Maria, chocolates flavoured with Malibu, vodka flavoured lip gloss and fudge and potato chips flavoured with Jim Beam whisky, the report says.

"By flavouring sweet or salty foods that are popular with children, alcohol companies such as Jim Beam are introducing young consumers to their brand at an early age, encouraging them to develop familiarity with, and loyalty to, their product,'' the report says.

Australian Medical Association president Dr Steve Hambleton said alcohol flavoured food was an attempt by the industry to "normalise'' alcohol.

"It's sending a subliminal message that everyone drinks.... your first drink could be a Tim Tam," he said.

Arnott's said the Tia Maria flavoured Tim Tams were a limited edition in 2004.

"Arnott's entered into a licensing agreement with Tia Maria to use their product flavour ...each Tim Tam Tia Maria biscuit contained less than 0.1% alcohol...the size of a small biscuit crumb''.

About 90 per cent of those aged as young as 14 have tried alcohol, says the report, which also states that five Australians aged 15-24 die each week from alcohol attributable injury and another 200 are hospitalised.

"Young people are starting to drink at an earlier age, and most drink in ways that put their health at risk,'' the report says.

As governments struggle for a policy solution to the death toll associated with king hits and drunken violence, the Australian Medical Association says it is no longer good enough for the alcohol industry to regulate its own advertising.

The voluntary Alcohol Beverages Advertising Code which is administered by the alcohol companies themselves says alcohol advertising should not encourage under-age drinking, appeal to children or encourage excessive alcohol consumption.

But the adjudication panel behind the code lacks any power to enforce it.

Despite the ABAC ruling four times that ads for the Three Kings drinks range encouraged youth drinking, the campaign continued to run.

The AMA wants the government to introduce laws to regulate alcohol advertising so penalties can be enforced, it wants alcohol sponsorship of sport phased out and alcohol sponsorship of youth music and cultural events banned.
