“…We use the term "adversities" in this paper to refer to the following negative childhood experiences: parental divorce, serious conflicts within the family, financial difficulties within the family, parents' frequent unemployment, parents' serious disease or disability, parental mental health and alcohol use-related problems, one's own serious or chronic illness, and bullying ( Table 1). The set of experiences assessed in this study have been investigated previously in the Finnish general population surveys Health 2000 and Health 2011, and found to be associated with adult mental disorders, including anxiety, depressive, alcohol use, and comorbid disorders (Markkula et al, 2017;Pirkola et al, 2005), heavy drinking (Kestilä et al, 2008), and daily smoking (Kestilä et al, 2006) in early adulthood. The adversities are also associated with shorter telomere length (Kananen et al, 2010), which is a biological marker of stress exposure (Mathur et al, 2016).…”
