Being too active at work could make you obese

Workers with physically demanding jobs who are inactive out of hours are at greater risk of obesity than those with a more even work-life balance, an international study has found.

Researchers from the University of South Australia in partnership with Denmark’s National Research Centre for the Working Environment, the University of Gävle, the University of Copenhagen and the University of Southern Denmark tracked the time-use behaviours of 807 blue-collar workers to investigate links between work, leisure and obesity.

Classifying workers into four unique behaviour profiles – Ants, Koalas, Lions and Chimpanzees – based on their distinct behaviours both at work and at play, the study found that while being active is generally considered to be healthy, being very active at work but stationary at home, could have the opposite effect.

The study recorded workers’ movements over four 24-hour periods (including at least two working days), tracking data via a triaxial accelerometer attached to their thighs. Workers also completed a paper-based diary to note their activities. Obesity indicators included waist circumference, weight, and body fat percentage.

University of South Australia researcher Dr Dot Dumuid said the findings contradicted popular health messages.

“Our research shows that Lions – people who spent much of their work time being active, but most of their leisure time sedentary or in bed – tended to have the highest risk factors for obesity, ” she said.

“This is contrary to what you might expect, that people who are sedentary both at work and play – those we have dubbed Koalas – would be most at risk of obesity, when this is not the case.

“Certainly, to prevent obesity, you need to exert energy – but looking at this in isolation is not showing us the full picture.”

Four distinct animal profiles were identified based on the work and leisure movement behaviours:

Ants: people who are active throughout the day, both at work and at leisure;

Chimpanzees: people who have a relatively even distributed composition of work and leisure behaviours;

Koalas: people who are more sedentary and less physically active at work and at leisure, while also spending more time in bed; and,

Lions: people who are very active at work, but mostly sit around at home and stay in bed longer.

Dr Dumuid said the study challenged the broadly-held notion that a lot of activity is a good way to prevent obesity, when in fact obtaining a balance of energy exertion was perhaps more important.

“An existing behavioural approach to prevent obesity is to exert more energy by increasing physical activity and reducing sedentary activity. However, this does not incorporate the recovery process – rest and sleep – which is also important for your body.

“If your body does not get enough time to recover, it can cause a state of chronic heightened inflammation, which can induce adverse effects, such as storing excess energy as fat.

“Similarly, someone who is very active at work, but crashes in front of the TV each night is not getting the right balance either – the body needs a balance of activity and recovery throughout the day, ” she said.

The study was published in the International Journal of Obesity.

“With the rise of obesity, public health messages rightly talk about being more active. But what they fail to convey is the importance of having a balance of active and restful activities across the day – both during work and leisure, ” Dr Dumuid said. — The Lead South Australia
