BACKGROUND: Gambling appears to be an independent risk factor for suicide among the young population worldwide. Blind boxes are collectable toys packed randomly in the box, which share certain similarities with gambling and are popular among the young population. This is the first study that examined the association between blind box engagement and suicide risk in the young population, the leading consumption group of blind boxes.
METHODS: This study is part of a large-scale, cross-sectional study using convenience sampling conducted Oct 26 to Nov 18, 2021, which covered all the university and college students in the Jilin province, China. A total of 73,206 participants completed the survey with valid data for the current study (male: N = 28,762; female: N = 44,444; Mean age = 19·59). Participants' blind box engagement, suicide risk, depression, anxiety, alcohol use, smoking habit, and sociodemographic characteristics were assessed. First, we used univariate and multivariable binary logistic regression models to examine the relationship between blind box engagement and suicide risk in all participants. Second, we tested whether depression and anxiety would mediate the association between blind box engagement and suicide risk. Third, we analysed the association between "Frequency (i.e., frequency of blind box engagement)," "Bet (i.e., expenditure on the blind box that exceeds affordability)," "Tolerance (i.e., level of addiction)," "Borrowed (i.e., the amount of money borrowed for blind box engagement)," and suicide risk in the group with blind box engagement history.
FINDINGS: 4,195 participants (5·73%) have engaged in blind boxes, with 3,255 females (77·59%) and 940 males (22·41%). In the univariate models, binary logistic regression showed that blind box engagement was associated with suicide risk in both male and female participants (male: OR = 2·21, 95% CI = 1·86-2·63; female: OR = 1·64, 95% CI = 1·50-1·78). In the multivariable models, after controlling age, subjective socioeconomic status, per capita disposable income, alcohol use, and smoking habit, blind box engagement still was associated with suicide risk across genders (male: OR = 2·25, 95% CI = 1·89-2·68; female: OR = 1·58, 95% CI = 1·45-1·73). Depression (male: indirect effect = 0·31, SE = 0·04, p < 0·001; female: indirect effect = 0·20, SE = 0·02, p < 0·001) and anxiety (male: indirect effect = 0·26, SE = 0·03, p < 0·001; female: indirect effect = 0·13, SE = 0·02, p < 0·001) mediate the association between blind box engagement and suicide risk. Within the blind box engagement group, forward binary logistic regression revealed that "Tolerance" was associated with participants' suicide risk in both males (p = 0·001) and females (p < 0·001); "Borrowed" (p = 0·019) alone was associated with the male participants' suicide risk.
INTERPRETATION: Our findings showed that blind box over-engagement is positively associated with suicide risk in both young males and females, and this association persisted after adjusting for influencing factors. In spite of the limitations in this study (e.g., cross-sectional, convenience sampling), current findings can assist policymakers in developing regulations for such a prosperous youth-dominant consumption industry while protecting youth's mental health worldwide. FUNDING: None.
