How can we tackle the problem of obesity?
“Overweight” and “obesity” rarely leave the headlines of our journals. This is inevitable, bearing in mind that obesity carries decreased
life expectancy brought about by cardiovascular disease, type 2 diabetes and
some cancers. Nevertheless, we neglect it as a risk factor in everyday living.
Worldwide, at least 1.1bn adults and 10 per cent of children are now either overweight
or obese, according to an editorial in the 13 May issue of The Lancet. Indeed,
the only region where the condition is uncommon is sub-Saharan Africa.
The main cause of the obesity epidemic is overeating, and particularly foods
rich in fats, extracted sugars or refined starches. The other major factor is
known to be a decline in physical activity, due to undue time spent in watching
television programmes, for instance. It is necessary to motivate people to eat
less, to choose healthier foods and to get plenty of physical exercise. This
may prove difficult where fruit and vegetables are expensive, high-fat processed
foods heavily promoted and a routine exercise schedule not practised.
It is reported that progress is slowly being made to remedy the situation. In
Europe the incidence of obesity, particularly in children, has risen threefold
since the 1980s and more than half the adults in most European countries are
known to be overweight — this has been accepted as a warning call for political
action. The World Health Organization has promoted meetings to discuss the role
of sport, transport, urban planning, education, leisure, agriculture and trade
in meeting the challenge.
In New Zealand, a worldwide agenda is being studied since 35 per cent of New
Zealander adults are overweight and another 21 per cent obese. One in five children
aged 5 to 14 is overweight and another 10 per cent obese. This has provoked swift
action.
In Europe, planning to provide safe green areas for walking, cycling or play
is progressing. Education in schools, on healthy eating and exercise is on the
agenda and new ideas about school meals abound. The difficulty lies in teaching
children to discriminate and not to follow crazes for eating, drinking and playing
games./p
