The present dissertation
has been designed to
predict
body comp
osition through a continuously expanding method in
Hungary, namely, bioelectrical impedance analysis
(BIA)
. A limiting factor of the method is that
the regressions
of
body fat content from the primarily measured impedance were validated for an
unknown popu
lation, therefore their use is not
justified
in other populations.
Our
goal
was
to develop regression
equation
s valid for
the
Hungarian population
by
us
ing the
sensor resistance data and anthropometric data in close correlation with body fat content,
depe
ndent of gender, age and maturity level; to be able to reliably predict body fat content between
the ages of 10
–
18.
The study sample was comprised of the subsample of the 1.5% randomized representative sample
of young people between the ages of 10
–
18 of th
e
2
nd
Hungarian
National Growth Stu
dy (2003
–
2006
)
. The necessity to develop the new regression prediction equations is shown by the fact that
the difference between the body fat content predicted by the BIA device and the reference method
(
Drinkwater
–
Ross
anthropometric fractionation method
)
was significant in both gender
s
, in the
majority of examined age ranges
.
Correcting the measurement results of the bioelectrical impedance analysis with the use of the new
regression equations, the body fat content of
Hungarian children between the ages of 10
–
18 can be
predicted more precisely: the difference between the median values of the predicted absolute body
fat content and the Drinkwater
–
Ross method barely exceeds 0.5 kg, meaning less than 2%. The
difference exp
ressed in percentages of the Drinkwater
–
Ross type prediction is on the average 1
–
4% in both genders for the studied age
interval
.
