Early-life influences on suicidal ideation, suicide attempts and suicide mortality: a life-courseperspective to inform prevention

Objective

Suicide is a major public health concern and leading cause of death worldwide. Suicidal ideation and attempts, especially
among youths, are of particular concern because of their associations with suicide, poor health, educational and employment
outcomes. The World Health Organisation European Mental Health Action Plan has ranked suicide prevention among the
highest priorities on the global public health agenda for 2020. While recognising the importance of immediate precipitating
factors (unemployment, relationship problems), studies worldwide are showing that early-life events, occurring before or
around birth, can influence later susceptibility to suicide. The LIFESPAN project adopts a life-course perspective to examine
the early-life influences (birth order, parental age, family/sibling size, birth weight, birth length) on suicide, suicidal ideation
and suicide attempts in the general population. It comprises 3 complementary objectives: (1) to summarise available studies
about the longitudinal relations between early-life influences and suicide mortality by applying meta-analysis, the statistical
approach most informative for policymakers, allowing to go beyond the heterogeneity of existing studies; (2) to investigate
the associations between early-life influences and suicidal ideation and attempts in adolescence and young adulthood with
data from 3 longitudinal population-based cohorts (from Canada and France; up to 25 years follow-up); (3) to identify specific
mediating pathways (targetable with new preventive interventions) linking early-life factors and suicide risk, using advances
longitudinal mediation analysis techniques relying on growth curve modelling. By shedding new light on the role of early-life
influence on suicidality, this project will contribute to the H2020 aim of “promoting healthy ageing and personalised health
care [which] will enable to better understand the determinants of health, keep the population healthier, preserve quality of
life”.
