2. THE OBJECTIVE
was to investigate 10-year trends of the main cardiovascular (CV)
risk factors (RF) in Slovakia among adolescents aged 16 to 17 years.
SUBJECTS and METHODS
The data were collected at preventive health examinations by the outpatient units across the country . The first survey (2001) consisted of 8850,
the second (2011) of 2165 participants.
Overweight and obesity were classified according the National reference
values of body mass index (BMI).
For prehypertension (PHT) and hypertension (HT) ESH (2009)
recommendations were used.
Cut off value for total cholesterol (TC) concentration was set at 5.2 mmol/L.
For the statistical evaluation ANOVA, Chi-square tests and odds ratios
(OR) were computed.

3. Mean values

The proportion
of obese and
overweight boys
significantly
increased over
10 years.

Figures in frames indicate total percentage
In adolescents with BMI in upper quartile
Prevalence of BP values in the range of
130-140 mm Hg significantly
increased, PHT and/or HT were found
in nearly 80% overweight boys and
more than half of girls.
Prevalence of TC levels ≥5.2 mmol/L
significantly decreased in all boys,
but only in lean girls.

5. Incidence and interrelation between risk factors
Overweight is associated with at
least 1 other RF in 3 of 4 boys and
3 of 5 girls.
Figures in columnes indicate the actual
percentage of respective RF in youth
population.
Clustering of high BP and TC
levels progressively increase with
the magnitude of the excessive
weight.
