Associations of Childhood Maltreatment with Single and Multiple Suicide Attempts among Older Chinese Adolescents.

OBJECTIVES: To test, among older Chinese adolescents, the associations of childhood maltreatment with single and multiple suicide attempts and whether these associations vary in relation to the presence of sleep disturbance.

STUDY DESIGN: We analyzed data collected from 10th to 12th graders from 7 randomly selected provinces of China in the 2015 School-based Chinese Adolescents Health Survey. There were 83 200 students who were invited to participate, and 75 715 students' questionnaires were completed and qualified for the survey. Adjusted multinomial logistic regression models were conducted to evaluate the associations of childhood maltreatment with suicide attempts.

RESULTS: Compared with no suicide attempts, each type of adjusted childhood maltreatment (physical abuse, emotional abuse, sexual abuse, physical neglect, or emotional neglect) was associated with an increased risk of single and multiple suicide attempts (P < .05). The magnitude of the aORs in multiple suicide attempters was greater than those in single suicide attempters. Moreover, the adjusted interaction effects for a single suicide attempt between each type of childhood maltreatment and sleep disturbance were all statistically significant in the multivariable multinomial logistic regression models (P < .001). However, the adjusted interaction effects for multiple suicide attempts were not significant (P > .05).

CONCLUSIONS: Maltreatment during one's childhood is associated with an increased risk of single and multiple suicide attempts among older Chinese adolescents. Sleep disturbances play a moderating role in these associations for a single suicide attempt.
