Perinatal circumstances and risk of offspring suicide: Birth cohort study

Using linked data from the Scottish Morbidity Record and Scottish death records, a birth cohort of 1061830 people was followed-up for a mean of 25.1 years. Data were analysed using Cox regression. Higher maternal parity, younger maternal age (<25 years), non-professional parental occupations and low birth weight (<2500 g) were independently associated with higher suicide risk of offspring as young adults. There was no independent association with gestational age.
