There

remains
a
challenge.
Objectives:
To
describe
the
characteristics
and
distribution
patterns
of
acne
scarring
and
associated
factors
in
young
males,
from
a
representative
sample
of
the
population
in
a
city
of
southern
Brazil.
Methods:
A
cross-‐sectional
study
was
undertaken
during
the
presentation
for
the
military
service,
which
is
compulsory
for
all
males
when
they
turn
eighteen
years
old.
A
questionnaire
was
applied
with
topics
on
diet,
smoking
habit,
ethnicity,
family
structure,
socio-‐economic
level
and
specific
questions
about
active
acne
and
its
scars.
Dermatologists
conducted
the
clinical
examination.
Results:
A
total
of
2.201
male
adolescents
were
enrolled
in
the
study.
The
overall
prevalence
of
acne
scarring
was
22%.
The
malar
region
was
the
most
frequently
affected:
more
than
eighty
percent
of
participants
had
scars
at
this
site,
followed
by
the
frontal
(31.5%),
back
trunk
(17%),
anterior
chest
(8.2%)
and
mentonian
region
(6.4%).
Correlation
between
the
intensity
of
clinical
acne
and
the
presence
of
scars
was
found,
but
no
association
was
observed
when
variables
such
as
education
level,
smoking,
ethnicity,
obesity
and
socio-‐economic
status
were
accounted
for.
Conclusions:
This
is
the
first
study
to
investigate
a
correlation
between
acne
scarring
and
factors
such
as
socio-‐economic
status
and
education
level.
Nevertheless,
larger,
population-‐based
studies
are
needed
to
settle
this
question.
The
direct
relation
16
between
acne
severity
and
scarring
indicate
that
prompt
and
effective
treatment
is
the
best
form
of
scarring
reduction.

de 85-90% em adolescentes (1,2). Um fator que adiciona impacto e importância
a patologia é a predominância nesta faixa etária, uma fase da vida que por si só
já carrega muitas preocupações com autoestima e imagem. Na grande maioria
dos casos a doença cessa aos 23-25 anos de idade, mas em até 14% dos
indivíduos o quadro pode persistir (3), e essaobservação contraria a afirmação
de que a acne é exclusivamenteuma afecção autolimitada própria da
adolescência. Em tais casos, a tendência atual é considerar o distúrbio como
uma doença crônica (4).
Mesmo nos casos em que há melhora ou resolução do quadro, o impacto
emocional pode persistir devido às cicatrizes da acne, que ocorrem
precocemente, e afetam 95% dos pacientes com a patologia. Até o momento, a
prevalência e fatores associados dessas sequelas não foram extensivamente
estudados. Layton et al (5)relacionaram a gravidade das cicatrizes com a
severidade e demora no início do tratamento da acne. Entre suas formas de
apresentação, tanto a acne pápulo-pustulosa quanto a nódulo-cística podem
causar cicatrizes.
O impacto emocional da acne e suas cicatrizes é bem documentado,
sendo causa frequente de distúrbios psicológicos. A doença já foi apontada
como importante fator de risco para suicídio, e estudos sugerem que o impacto
emocional é comparável ao de doenças sistêmicas como diabetes, asma, artrite e
epilepsia (6,7).
O tratamento das cicatrizes de acne é desafiador. Há inúmeros trabalhos
sobre diferentes técnicas, invasivas ou não e com variáveis custos. A dificuldade
também reside na comparação entre as várias opções de tratamento pois há falta
de consenso na nomenclatura e classificação das lesões, e da mesma forma
estudos com boa qualidade metodológica são escassos(8).
O presente estudo objetiva trazer novas evidências sobre fatores
associados a acne e cicatrizes, tendo como vantagem a avaliação dos
4
participantes por profissionais experientes em dermatologia. A maioria dos
trabalhos utiliza apenas questionários auto-referidos, o que já foi demonstrado
ter baixa sensibilidade e especificidade para definição de casos (9).
