We investigated correlates for suicidal expression among adolescents in the Seychelles. Data on 1,432 students (52% females) were derived from the Global School-based Health Survey. Participants were divided into three groups: those with no suicidal behavior (N = 1,199); those with suicide ideation/SI (N = 89); and those reporting SI with a plan to carry out a suicide attempt/SISP (N = 139), each within a 12-month recall period. Using multinomial logistic regression, we examined the strength of associations with social, behavioral and economic indicators while adjusting for covariates. Sixteen percent of school-attending adolescents reported a suicidal expression (10% with a plan/6.2% without). Those reporting SI were younger (relative risk ratio RRR = 0.81; CI = 0.68–0.96), indicated signs of depression (RRR = 1.69; CI = 1.05–2.72) and loneliness (RRR=3.36; CI =1.93–5.84). Tobacco use (RRR = 2.34; CI = 1.32–4.12) and not having close friends (RRR = 3.32; CI = 1.54–7.15) were significantly associated with SI. Those with SISP were more likely to be female (RRR = 0.47; 0.30–0.74), anxious (RRR = 3.04; CI = 1.89–4.88) and lonely (RRR = 1.74; CI = 1.07–2.84). Having no close friends (RRR = 2.98; 1.56–5.69) and using tobacco (RRR = 2.41; 1.48–3.91) were also strongly associated. Having parents who were understanding was protective (RRR = 0.50; CI = 0.31–0.82). Our results suggest that school health promotion programs may benefit from targeting multiple factors associated with suicidal expression. More research, particularly multilevel designs are needed to identify peer and family influences which may modify associations with suicidality.
