Suicide Risk in Relation to Level of Urbanicity – a Population-Based Linkage Study

This study investigated suicide risk in relation to the level of urbanicity in the context of other factors & studied risk variation in a gender, age, & calendar year perspective. A nested case-control study comprising 21,169 suicides & 423,128 Danish population controls was done. Data were analyzed with conditional logistic regression. Suicide risk associated with urbanicity varied significantly by gender & age groups. Recent years saw a decline in urban-rural disparities among men. The increased risk in urban areas can largely be explained by the effects of marital status, ethnicity, income, & psychiatric status. (35 refs.)
