The objective of this study based on Swedish registers is to examine the influence of socioeconomic position on poststroke divorce and separation using education as a marker. People aged 18 to 64 who suffered a first stroke between 1992 and 2005 were included if they were married or cohabiting and had mutual children. The material included 42,026 first stroke cases and 424,281 nonexposed persons, both populations divided into three different educational groups. Results show that the risk of separation is much higher in the incident year and in the first poststroke year, above all among people with only compulsory (elementary) education.
