Suicide in children and adolescents is commonly underreported and studied. It is an interplay area of multiple static (sociodemographic), and modifiable (impulsivity, psychiatric morbidities, adverse life events (ALE), abuse, bullying) variables.

To assess and identify relative significance of dependent and independent risk factors in youngsters attempting self-inflicted poisoning.

Consecutive recruitment of patients aged 7–18, with normal IQ, admitted to poison control centre over 13 continuous months, with self-induced poisoning. All were assessed after guardians’ written informed consent for different risk factors identified for suicidal behavior using appropriate scales (PPS, SRRS-Y, FSSCS, BIS-11, J-TCI, Mini-Kid). Controls with no history of suicidal attempt were matched for age, sex and sociodemographics among their families.

One hundred and twenty cases (16.7 years ± 1.6 SD, 91% females) and 100 controls (age 16.4 years ± 1.7 SD, 90.8% females) were assessed. In cases, 90.8% were of low/middle socioeconomic status, 73.5% had previous attempt, average within 10 months, 17.5% planned their attempt, 10.8% had a witnessed attempt. Stressor within 2 days was reported in 75.9%, severe in 40%. Impulsivity was more in its cognitive, planning and motor components (P = 0.001 in each) among attempters. Cases scored more on Novelty seeking, harm avoidance and reward dependence than controls who had more persistence, self-directedness and cooperativeness. Attempters had significantly more past medical and psychiatric history (P = 0.001, 0.05 respectively), 77.5% had a working psychiatric illness, 2% in controls.

Repeated suicidal attempts were the majority, with impulsivity as a predictive risk, especially if psychiatric morbidity or ALE in youths were encountered.
