Parental role and peer support in adolescent suicidal behavior in eight South-East Asian countries

Background: This study aimed to estimate the prevalence of suicidal behaviors, i.e. suicidal ideation (SI), suicidal plan (SP), and suicidal attempt (SA) among adolescents with a focus on parental and peer support in eight SouthEast Asian countries including Bangladesh, Bhutan, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka and Thailand. Method: Data were drawn from Global School-based Student Health Survey (GSHS) covering 42,888 adolescents aged 11-17 years. Weighted prevalence of SI, SP, and SA along with country specific prevalence was computed and binary logistic regression was used to identify associated risk factors. Results: Among 42,888 adolescents 19,113 (44.9%) were males and 23,441 (55.1%) females. Overall prevalence of SI, SP and SA is 9.10%, 10.42% and 8.54%, respectively. Myanmar demonstrated the lowest SI (1.07%) and SP (0.18%) whereas lowest SA was found in Indonesia (3.79%). Maldives had the highest prevalence of SI, SP and SA which were 14.13%, 19.02% and 13.38% respectively. Overall suicidal behaviors were associated with being female [AOR: SI-1.26 (1.06,1.50), SP-1.34 (1.14,1.57)], high levels of sedentary behavior [AOR: SI-2.08 (1.62,2.66), SP-1.86 (1.49,2.32), SA-1.96 (1.45,2.64)], involvement in physical fighting [AOR: SI-1.30 (1.07,1.58), SP-1.37 (1.14,1.65), SA-1.50 (1.17,1.90)], being seriously injured [AOR: SI-1.40 (1.17,1.67), SP1.44 (1.22,1.69), SA-1.74 (1.39,2.17)], being bullied [AOR: SI- 1.68 (1.39,2.02), SP-1.34 (1.12,1.60), SA-1.88 (1.50,2.36)], feeling lonely (most of time or always) [AOR: SI-3.41(2.60,4.46), SP-1.92 (1.48,2.47), SA-2.25 (1.62,3.13)], lack of parental support (never checking homework) [AOR: SI-1.59 (1.25,2.02), SP-1.52 (1.22,1.90)] and not having close friends [AOR: SI-2.19 (1.66,2.89), SP-2.26 (1.74,2.94), SA-4.23 (3.10,5.78)]. Conclusion: Though prevalence of suicidal behaviors varies, a range of cross-cutting risk factors exists that warrant further examination. We recommend focusing on strengthening parental and peer support, targeted programs addressing physical activity, bullying, loneliness and mental-health of adolescents.
