The authors regret that there was an error in the Introduction on page 262, paragraph 3, in which the word “longer” should have been “shorter.” Thus, the sentence beginning “Longer childhood buccal telomere length” should have read “Shorter childhood buccal telomere length has been reported with higher percent time institutionalized in Romanian orphanages (Drury et al., 2012), a designation of “high risk” for maltreatment according to child welfare services (Asok et al., 2013), and exposure to family violence and family disruption, particularly in girls, in a sample of predominantly African American youth (Drury et al., 2014).” In addition, in the Introduction, page 262, right column, 2nd full paragraph, the following sentence had a word duplication, and should read: “Other investigations of mtDNAcn from blood samples have reported an association of cell-free mtDNAcn from plasma with MDD (Lindqvist et al., 2018), no association with depressive symptoms (Verhoeven et al., 2017), or a decrease of mtDNAcn in peripheral blood mononuclear cells (PBMCs) of older adults with MDD (Kim et al., 2011) and in granulocytes of male combat veterans with PTSD compared to those without PTSD (Bersani et al., 2016).
In addition, in the Discussion on page 266, paragraph 3, line 12, the sentence beginning “Telomere lengthening over time has previously been reported….” could be confusing, particularly in light of the error in the Introduction. This sentence should be clarified as follows: “Telomere lengthening has previously been reported in a minority of children followed from age 5 to 10 (Shalev et al., 2013), and a study that found overall shorter telomeres with several markers of neighborhood level disorder reported that lower socio-economic position was associated with longer telomeres (Theall et al., 2013).”
