Although the very old group exhibited a four-fold to five-fold increase in risk of suicide for those previously hospitalised, we noted an inverse interaction effect: the increase is distinctly smaller compared with that in the middle-aged and old groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The association between suicide and psychiatric hospitalisation is much weaker for the very old than for the old.
