Abstract
This pilot study was supported by CONI within a
campaign against doping. It was aimed at
preliminarily assessing the value and feasibility
of the Noopolis “Healthy Growth Charter”
project, designed to check at regular intervals
the whole young population for various items of
statistical and medical interest.
1500 children of both sexes, 8-12 yrs, from …
3
18 Italian regions out of 20, fulfilled a
questionnaire on height, weight, dental and
sight problems, knowledge of Mediterranean
anemia, sport practice.
The Body Mass Index (BMI) distribution was
in line with that reported by Cacciari et al.
(2006). 60 % of children had experienced
toothache, 80 % underwent a dental visit …
4
and up to 15% used orthodontic devices.The
blackboard test indicated visual problems in
24% of children, suggesting in 8% of cases a
possible amblyopic defect. 12% used lenses.
The knowledge of Mediterranean anemia
increased with age, approaching 50% at 12
years.
Children practicing sport were over 80% …
5
at 9 years and 70% at 11 years. Football was
the favorite discipline in male and dance in
female. Obesity occurrence was minimal in
association with football practice.
This study stresses the potential value of the
Noopolis “Healthy Growth Charter” and
suggests that, after appropriate refining, it
could become part of the educational career of
young people.

Introduction
Growth charters for children are derived from
large, representative cross sectional surveys in
US (Flegal et al., 2002), Canada (Anonymous,
2004), UK (Wright et al., 2002), Italy (Cacciari
et al., 2006) and other areas (de Onis et al.,
1996).
These charters, however, are not currently used
to monitor the growth of the whole population.
Another information about anthropometric
parameters and some other items of …
7
medical interest was collected in occasion of
the obligatory enrollment army visit. This
information, however, was limited to males and
in Italy and some other countries the obligatory
army service has been abolished.
The present study was supported by CONI
within a campaign against doping. It was aimed
at assessing the Noopolis “Healthy Growth
Charter” project, which to our knowledge is the
first, consistent attempt to fill the above two
gaps.

Subjects and methods
The study involved 4000 primary schools in 18
out of 20 Italian regions, with an average of 70
students each. Hence the potential sample was
of 279.580 subjects from 6 to 12 years .
The Directors of the schools were contacted by
mail with a personal letter. They were sent
booklets with an illustrated story on doping; a
questionnaire situated on the back cover …
9
of the booklet; 3 public notices; a DVD
containing all the above material. They were
asked to adhere to the campaign, distribute the
booklets and return back the filled
questionnaires.
2776 Directors out of 4000 expressed their
interest, which corresponded to about 190.000
students out of 279.580. The questionnaire …
10
was administered only to students of 8-12 yrs,
amounting roughly to 100.000 subjects. The
filled questionnaires sent back were 1500,
corresponding to about 1.5% of the involved
sample.
The agency entrusted with the campaign and
related tests was Angelicum Film SrL, Milan.

Discussion and Conclusions
Height and weight: values in line, despite less
accurate measures, with previously reported
values (Cacciari et al., 2006).
Obesity: also in line, deserving attention both by
itself and in connection with the corresponding,
related condition in the adult (Nader et al.,
2006).
46
Discussion and Conclusions
Dental problems: quite common, earlier in
females, high frequency of medical control and
orthodontic devices. Some inverse relation
between the latter two and obesity, which might
be indirect, due to cultural or psychological
reasons.
47
Discussion and Conclusions
Visual problems: quite common as well, use of
lenses averaging 25 %. The consistent
indication of possible undiagnosed amblyopic
defects deserves careful attention.
Mediterranean anemia: a surprisingly widespread knowledge in children, probably
connected with current educational campaigns
in schools.
48
Discussion and Conclusions
Sports: widely practiced, probably mostly out of
schools, football and dance being the preferred
ones in males and females respectively.
A clear-cut inverse relation was found between
sport practice and obesity, football being the
most effective one.

Noopolis “Healthy Growth Charter”
Project
This study confirms the potential value of an
extended growth charter in the prevention and
treatment of some common conditions. At the
same time it points out some substantial
adjustments:
• Other items should be considered, such as
hearing, color-blindness, dyslexia and
additional clues of learning and behavioral
problems.
50
Noopolis “Healthy Growth Charter”
Project
• The survey must be anticipated as much as
possible and repeated at least two more times,
around puberty and after adolescence.
• To accomplish the above goals, the
questionnaire should be adapted to each age,
with particular reference to the first one.
51
Noopolis “Healthy Growth Charter”
Project
• To cover the whole young population, the
survey has to become a duty, within the
scholastic curriculum.
• In other words, the “Healthy Growth Charter”
ought to become a State issue.
52
Noopolis “Healthy Growth Charter”
Project , with associated campaigns
Last but not least, this pilot study was
associated with a campaign against doping,
designed and conducted with the active
involvement of young people. This positive
experience should be renewed with the
extended Healthy Growth Charter, which
provides a unique opportunity to interact with
the whole young population.
