Guide Voice: Are you getting enough sleep?
If you are getting less than five hours a night, you could be
doubling your risk of becoming obese, according to a research study
presented at the International AC21 Research Festival, hosted by
the University of Warwick this month.
Concerns over obesity have long been widespread in the USA,
where the relationship between exercise, diet, weight and health
are being studied extensively, but now the World Health
Organisation is looking at increases in Europe too, and is
developing a charter to organise immediate action to curb obesity
in the region.
00:31 SOT: Francesco Branca, Adviser on Nutrition and
Food Security, European Regional Office, World Health Organisation
- “It is indeed a serious problem, a high body
mass index is one of the key risk factor for non-communicable
diseases which are responsible for the majority of deaths in
Europe. We have seen an increase in the last 30 – 40 years
and now most of the countries in the European region are affected.
We have up to two thirds of the population which is affected by
overweight and now the problem is becoming increasingly important
for children.”

Guide Voice: This link between lack of sleep
and obesity is an early finding of a study by Professor
Francesco Cappuccio of the University of Warwick’s Medical
school.
He examined current evidence in over 28,000 children and 15,000
adults and discovered that sleeping less than 5 hours a night is
associated not only with a greater increase in body mass index and
waist circumference over time. but alarmingly, with almost a
twofold increase in the risk of obesity for both groups.
01:30 SOT Professor Francesco Cappuccio, The
MedicalSchool, University of Warwick - “Parallel
to an epidemic of obesity in the western world we found that since
1910 particularly in the US where they have been collected more
comprehensively there has been a rapid decline in the number of
hours we sleep per night from about over 9 hours a night to less
than 7 and this seems to be associated with an increasing level of
chronic conditions.”

Guide Voice: Like other factors contributing to
obesity, food choices, lack of exercise, it seems to be a lifestyle
issue.
02:01 SOT Francesco Branca, WHO, European Regional
Office - “This is an interesting piece of
research and putting together different lifestyle aspects with food
choices. The choice of food is very much determined by what is
around so the obese environment is what we need to research more so
the integration between medical research and socio-political
research is something we should be exploring more.

Guide Voice: Some of Professor
Cappuccio’s findings also provide a potential reason for the
connection between sleep and an increase in appetite.
02:32 SOT Professor Cappuccio - “This
data also show that there are plausible mechanisms by which these
associations may be explained by. The change in hormones, one
called leptin and one called ghrelin may affect the level of
appetite and they may be directly effected by the lack of sleep. So
in actual terms some of the research shows that one of the possible
mechanisms of explaining the findings is a hormonal mechanism
leading to eating more.”

Guide Voice: Professor Cappuccio wants to
explore the area further, looking at how short sleep may be linked
to other conditions like diabetes and hypertension, as well as
obesity, which according to the WHO now affects one in three
children in Europe alone and that is growing at a rate of 1 to 2
per cent a year.
