Objectives:
Suicide is one of the leading
causes of death in
adolescence, and the second most common
cause of death among young people. The objective of this study was to identify
trends in
suicidal ideation by
sex and ascertain factors associated with this outcome.
Methods:
Secular trend study with statewide coverage conducted at 5-year intervals, with 4,207
adolescents (2006), 6,264
adolescents (2011) and 6,026
adolescents (2016).
Logistic regression was used to evaluate the secular trend of
suicidal ideation. Multilevel
logistic regressions evaluated the factors associated with
suicidal ideation in the
survey conducted in 2016.
Results:
There was a positive trend in
suicidal ideation prevalence in 2016 compared to the
prevalence in 2006 and 2011, in both
boys and
girls. Low
social support, poor
sleep quality, and low parental
supervision were associated with
suicidal ideation in
boys and
girls.
Exposure to violence and
bullying was associated with
suicidal ideation only in
girls. TV
time and
computer and videogame
time were not associated with
suicidal ideation in
boys or
girls.
Conclusion:
There is an alarming trend of increased
suicidal ideation in
adolescents. Several dimensions were associated with
suicidal ideation in
adolescents, especially
social support,
sleep quality, and parental
supervision.
