Background
Adverse life events or the commencement of adverse lifestyles associate with suicidal ideation, but most associations only have been identified in cross-sectional studies. More information is needed about whether they are true risk factors and independently predict the development of suicidal ideation.
Method
A sample of the general population from Eastern Finland (n = 1,339) was followed-up for three-years with baseline and two follow-up assessments using postal questionnaires. The main adverse life events and changes in lifestyles were screened at baseline and on one- and three-year follow-up. The Beck Depression Inventory was used to assess the level of depression and the presence of suicidal ideation.
Results
Suicidal ideation was common in the sample (annual incidence 4.3%). At baseline it associated with a cluster of adverse life events and lifestyles, as well as depression. Nevertheless, only the Beck Depression Inventory score on 3-year follow-up (OR 1.33, 95% CI 1.22–1.45) and the onset of daily smoking during the follow-up period (OR 5.38, 95% CI 1.41–20.62) independently predicted the presence of suicidal ideation on 3-year follow-up among those who had been non-suicidal at baseline and on 1-year follow-up.
Conclusion
Depressive mood appears to be a necessary precondition for the occurrence of suicidal ideation even after adverse life events.
