The Division of Exercise Science and Sports Medicine (ESSM)
of the University of Cape Town, based at the Sport Science Institute of South
Africa (SSISA) in Newlands, is investigating how well overweight and obese
South Africans sleep, compared to their lean counterparts.
recruitment for the two groups is now open. Men with a waist circumference of
102cm or less or women with a waist circumference of 88cm or less in
combination with a BMI of less than 25 will be categorized in the lean group,
and for those who have a BMI equal to or greater than 25 and a waist
circumference greater than the abovementioned limits will be categorized in the
overweight and obese group.
Participation involves two (for the lean group) or four (for
the overweight and obese group) visits to the SSISA. During the first visit we
ask you to complete a questionnaire and perform a fitness test. We will also
measure your height, weight, body composition, resting blood pressure, fasted
cholesterol and blood sugar. Finally, we will take a blood sample and a swab of
loose cheek cells for DNA analysis. We will then ask you to wear a watch-like
device that records your activity and sleep for the following seven days. The
second visit is solely to return the device (a pick-up can be arranged). For
those in the lean group, the study ends here (total of two visits). For those
in the overweight and obese group, we will contact you 8 weeks later to perform
the same tests again (total of four visits). That’s it!
Unfortunately, there will be no remuneration for
participating, but we will do our best to make your participation a fun
experience! We will also share the general and your personal results with you.
Please note that all participants must be 20 years or older, free of sleep
disorders or sleep disturbances (e.g. currently breastfeeding), and not be
involved in night-time shift work.
