Even more caffeine research

There is a lot of research going on at the moment into coffee and caffeine. There seems to be no particular reason but perhaps the increasing sales of “energy drinks” may be relevant.

The latest caffeine-related research is reported in the online edition of Neuropsychopharmacology and is entitled –

“Association of the Anxiogenic and Alerting Effects of Caffeine with ADORA2A and ADORA1 Polymorphisms and Habitual Level of Caffeine Consumption”

(This paper is on my bedside table next to an Inspector Rebus book and the new book from Chris Morphew – not)

This quite complex article is mentioned here as some newspapers and websites are likely publish some of the content of a media release on 3 June 2010 in the context of “another coffee story”. Research in this area can spark discussion in some media about the dangers and benefits of coffee, in a similar way to how people respond to reports of eating too many tomatoes that may turn you puce, for instance. Below are parts of the media release that is easiest to understand and are likely for the media to cover:

“The sensation of alertness that comes from a cup of coffee may be an illusion. Continue reading “Even more caffeine research”

Looking for the causes of workplace harm can change one’s world view

The New York Times reported on 17 May 2010 that psychologists have started considering the causes of workplace stress. About time!

The report says that

“Employees are unhappy about the design of their jobs, the health of their organizations and the quality of their managers..”

and that unhappy workers have a high risk of heart attacks and depression.

The article is principally an interview with the author of a new personnel management book that identifies that performance reviews are a generator of unhappiness and stress. This concept has been circulating for some time and goes part way to making workplaces safer.

Job design, mentioned above, can be broadened to include how people are managed. Personnel management and human resources (HR) are a crucial element of any business but the NYT article indicates a growing realisation that the foundations of this management, how jobs are designed, have generated some of the hazards that HR is now tasked to control.

Shiftwork saviour? – Caffeine (sort of)

Caffeine is a commonly used stimulant in many workplaces around the world. As such, it is often considered to be the friend of the shift worker and a new analysis of research findings may make that friendship stronger.

According to a new study from Cochrane researchers:

“The results of this systematic review suggest that caffeine may be effective in improving performance in persons engaged in shift work or suffering from jet lag, although it may not be possible to confidently translate such an improvement in performance to a reduced injury risk.” Continue reading “Shiftwork saviour? – Caffeine (sort of)”

Shift work research findings are grounds for big concern

A scientific symposium held in Canada in April 2010 has raised some serious concerns about the health impacts of shift work. Some of the evidence has existed for a while but collecting it all together makes one wonder how companies can justify shift work in the face of such high risks to workers’ health.

From the evidence presented at the symposium, workers will be tired at work when working shift work and are more likely to be injured than those on day shift. Some workers have an increased risk of breast cancer. Foetal growth in some pregnant women may be impeded. Circadian disruption may encourage the growth of tumours and an international agency is convinced sufficiently of the risks to determine that shift work itself is probably carcinogenic.

The Occupational Cancer Research Centre and the Institute for Work & Health should be applauded for making the evidence presented at the symposium publicly accessible. Continue reading “Shift work research findings are grounds for big concern”

Employees’ OHS responsibility and working beyond the maximum hours

One of the most powerful motivators for behavioural change in workplaces is the legislative obligation on employees to not put themselves at risk of injury nor to act in such a way as to place others at risk.

Reported in the Australian media on 31 March 2010, Fair Work Australia has ruled that employees in the fruit-picking industry may volunteer for work beyond the standard 38-hour week without receiving penalty rates or overtime. The union movement is understandably concerned about how this financially disadvantages workers and how this ruling may spread beyond the fruit-picking industry.

The ruling allows fruit-pickers to choose to work beyond their regular shifts. Will they be able to work safely? Will they not be fatigued? Will they have sufficient daylight to undertake the tasks safely? Will there be sufficient downtime for workers to recover from a long work day and be fit for work? Could the workers’ choice to undertake additional fruit-picking tasks be a breach of their OHS obligations to look after their own safety, health and welfare?

The employees may choose to ignore their own occupational health for the sake of additional dollars but should they then be eligible for workers’ compensation if the effects of those longer hours are found to have contributed to an injury or illness? Continue reading “Employees’ OHS responsibility and working beyond the maximum hours”

Does being fat equate to being unsafe at work?

There are several initiatives throughout the world under the banner of workplace health that have little relation to work. They are public health initiatives administered through the workplace with, often, a cursory reference to the health benefits also having a productivity benefit.

So is a fat worker less safe than a thin worker? Such a general question cannot be answered but it illustrates an assumption that is underpinning many of the workplace health initiatives. There is little doubt that workers with chronic health conditions take more leave but, in most circumstances, this leave is already accounted for in the business plan.

Sick leave is estimated at a certain level for all workers across a workplace and, sometimes, a nation. There is an entitlement for a certain amount of sick leave for all workers, fat and thin, “healthy” or “unhealthy”. It certainly does not mean that the entitlement will be taken every year but the capacity is there and businesses accommodate this in their planning and costs.

Remove this generic entitlement so that only working hours remain. Is a fat worker less productive than a thin worker? Is a worker without any ailments more productive than a person with a chronic ailment? Is a smoker more productive than a non-smoker or a diabetic or a paraplegic? Continue reading “Does being fat equate to being unsafe at work?”

Is overwork part of the Australian Government’s project management difficulties?

On the Insiders television program on 21 February 2010, host Barrie Cassidy closed a long interview with the Communications Minister Stephen Conroy but asking about the workload of public servants in supporting government programs. The video is available on-line and the comments are at the 11 minute mark.

Conroy says that the “cracking pace” the Prime Minister, Kevin Rudd, established from the start of his government has continues. Rudd continues to expect high performance from his Ministers, staff and public servants. Conroy talks about the change that has been demanded of the public service and that this has generated more workload. He forecasts that the workload may ease if the Government achieves a second term of office.

Cassidy makes the link between the “pushing people too hard” and the failure of Government schemes such as the insulation scheme that was cancelled by the Environment Minister, Peter Garrett on 19 February 2010.
