Recently a study on the relationship of the 2008 global economic crisis on suicide has been published by the BMJ . Unfortunately this paper contains a number of inaccuracies and omissions and we wish to comment on them. The most important are as follows:
1. The authors again and again in this publication, as well as in previous ones suggest there is an increase in suicides after 2007 in spite of the fact that for example for Greece during that year there was a random trough in suicide rates followed by the usual rate for 2008-9 . Similar issues have been raised concerning the interpretation of data from other countries .
2. In the current as well as in previous publications the authors utilize a linear model which is clearly not appropriate for suicide data, given their very high variability across countries and continents.
3. In spite of the fact that they correlated ‘change in unemployment’ with ‘suicidal rates’ (a very sensitive choice of variables), they failed to detect any significant correlation (p>0.05). Even if significance is not taken into consideration, the coefficients were too small (0.25 for men and 0.10 for women) to deserve discussing them. Still the authors consider this to be a major finding.
4. The authors do not seem to take into consideration the possibility that unemployment might not be a crucial factor concerning suicidality. They mention (but fail to comment) that a 37% rise in unemployment was accompanied by an only 3% fall in GDP during 2009. In a previous publication it has been mentioned that unemployment and suicidality regression lines were identical concerning the US data , however they failed to mention that the rise in suicidality preceded for one year that of unemployment . In the current paper it is interesting that they avoid plotting both the suicide rate and unemployment rate vs year in the same plot.
5. The authors report an excess of 4900 suicides in the year 2009 in comparison to their predictive model. However even if one looks closer at the data presented, significant increases in suicidal rates were observed for females only in 19 countries and in 33 for males (out of 54).
6. The hypothesis that the economic crisis is largely responsible for the increase observed in specific countries is in contrast with the reporting of the authors that a large portion of the increase concerns males aged 15-24 and the increase is smoothly distributed through the ages 15-64. It is also in sharp contrast to the recent finding that the increase in female suicides is mainly responsible for the increase in the suicide rate in Greece for the year 2011 .
7. In the discussion, concerning Greece, in spite of previous publications with overlapping authors [7-10], the authors of that paper fail to give the acurate picture of suicidality and mental health in Greece today [2 3 6 11 12].
Conclusively, it seems that suicides are increasing in the last few years. The population aged over 15 of the countries included in that study is roughly 1.1 billion people and the increase in suicides corresponds to around 0.44 per 105 residents. Since the average world suicide rate is above 10 and probably around 16 per 105 residents, this change is below 5% and probably non or marginally significant However this should not cover the fact that the trend is rather clear still premature to interpret. The role of the economic crisis and austerity is unclear, mainly because the data fluctuate with a period of decades, they manifest huge variability, peculiar changes in subgroups (e.g. mainly an increase in female suicides in Greece during 2011) and because the temporal correlations are problematic.
