Abstract
Purpose: Evidence linking screen time and physical activity with suicidality among adolescents is inconsistent. Our objective was to examine longitudinal associations between screen time and physical activity with suicidality among Danish adolescents.
Methods: Self-reported data on daily screen time and physical activity at age 11 was obtained from 28 613 adolescents (60% females) who participated in the Danish National Birth Cohort and linked to information on suicidality at age 18, based on self-reports and register data. Adjusted relative risk ratios (aRRR) were estimated using multinomial logistic regressions, while accounting for parental socio-demographics, psychiatric history and child risk behaviours.
Results: High levels of daily screen time (≥ 6 h) were reported by 6.9% and 12.6% of females and males, respectively. This was associated with suicidal ideation in females (aRRR:1.67, 95% CI:1.44-1.93) and suicide attempt in both sexes (females: aRRR:2.04 [1.51-2.75], males: aRRR:3.61 [1.89-6.89]) when compared to adolescents with < 2 h of daily screen time. Low levels of physical activity were reported by respectively 13.4% and 14.8% of females and males and was associated with increased risk of suicidal ideation (females: aRRR:2.18, [95% CI:1.94-2.44], males: aRRR:2.11 [1.83-2.43]) and suicide attempt (females: aRRR:2.27, [1.77-2.91], males: aRRR:2.49 [1.61-3.85]) when compared with those with the highest level. Independently of screen time level, males with low physical activity had higher risk for suicide attempt compared to males with a high level of physical activity.
Conclusion: High levels of screen time and low levels of physical activity were associated with an increased risk of suicidality among adolescents.
期刊介绍：
Social Psychiatry and Psychiatric Epidemiology is intended to provide a medium for the prompt publication of scientific contributions concerned with all aspects of the epidemiology of psychiatric disorders - social, biological and genetic.
In addition, the journal has a particular focus on the effects of social conditions upon behaviour and the relationship between psychiatric disorders and the social environment. Contributions may be of a clinical nature provided they relate to social issues, or they may deal with specialised investigations in the fields of social psychology, sociology, anthropology, epidemiology, health service research, health economies or public mental health. We will publish papers on cross-cultural and trans-cultural themes. We do not publish case studies or small case series. While we will publish studies of reliability and validity of new instruments of interest to our readership, we will not publish articles reporting on the performance of established instruments in translation.
Both original work and review articles may be submitted.
