In
two
nationally
representative
surveys
of
U
.
S
.
adolescents
in
grades
8
through
12
(
N
=
506
,
820
)
and
national
statistics
on
suicide
deaths
for
those
ages
13
to
18
,
adolescents
’
depressive
symptoms
,
suicide
-
related
outcomes
,
and
suicide
rates
increased
between
2010
and
2015
,
especially
among
females
.
Adolescents
who
spent
more
time
on
new
media
(
including
social
media
and
electronic
devices
such
as
smartphones
)
were
more
likely
to
report
mental
health
issues
,
and
adolescents
who
spent
more
time
on
nonscreen
activities
(
in
-
person
social
interaction
,
sports
/
exercise
,
homework
,
print
media
,
and
attending
religious
services
)
were
less
likely
.
Since
2010
,
iGen
adolescents
have
spent
more
time
on
new
media
screen
activities
and
less
time
on
nonscreen
activities
,
which
may
account
for
the
increases
in
depression
and
suicide
.
In
contrast
,
cyclical
economic
factors
such
as
unemployment
and
the
Dow
Jones
Index
were
not
linked
to
depressive
symptoms
or
suicide
rates
when
matched
by
year
.
