This study examined whether early onset of depression is associated with the degree of intent of suicidal behaviour & whether this relationship differs according to gender. Relevant responses from 9,282 American residents were drawn from a nationally representative community survey done in 2001-2003. Younger age of onset for depression was associated with higher levels of suicidal intent, irrespective of age at the time of interview. A significant interaction between level of intent & age at interview appeared to be accounted for by the later onset among those in the eldest cohort who reported an absence of suicidal behaviour. The influence of suicidal intent on onset of depression was greater for women than for men. (49 refs.) JA
