Associations between joint lifestyle behaviors and depression among children and adolescents: A large cross-sectional study in China
Abstract
BACKGROUND
Lifestyles in children and adolescents are associated with mental health, yet the combined effects of diet-related joint lifestyles on depression are unclear.
METHODS
A cross-sectional study was conducted in January 2020 in primary and secondary schools in Shanghai, China, with 6478 participants in the analysis. Lifestyle behaviors (physical activity, sleep duration, screen time, and diet quality) and depressive symptoms were measured using validated questionnaires. A series of multivariable logistic regressions were performed to examine the associations between lifestyle behaviors and their combinations and depression.
RESULTS
The prevalence of depressive symptoms 12.2 % (n = 788). Compared to those considered physically active, physically inactive individuals showed higher odds of depression (adjusted odds ratio [aOR] = 1.206). Similarly, insufficient sleep duration (aOR = 1.449), long screen time (aOR = 1.457) and poor diet quality (aOR = 1.892) were all associated with higher odds of depression. Compared to participants with behaviors meeting all guidelines, the odds of depression increased as the number of behaviors not meeting guidelines increased in a dose-response relationship, with an average increase in depression odds of 49 % on average for each additional unhealthy behavior. Moreover, different combinations of behaviors not meeting guidelines showed varied odds of depression.
CONCLUSIONS
Our research suggests that lifestyle behaviors not meeting…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 6,478 participants or records.
