  Depression has been linked to an imbalance in cortisol. Until recently, cortisol has been studied by measuring concentrations at single time points in blood or saliva samples. Cortisol concentrations vary with circadian rhythm and experiences, from time point to time point. The measurement of hair cortisol concentration (HCC) is a new method of accessing mean, long-term cortisol concentrations. Recent studies show positive associations between depression and HCC, and prenatal maternal cortisol is thought to influence the developing fetus. We therefore examined the association between HCC and self-reported symptoms of depression in second trimester pregnant women. Participants were 181 women, recruited between September 2011 and October 2013 to the Little-in-Norway (LiN)-study. These women answered the Edinburgh Postnatal Depression Rating Scale (EPDS) on self-reported symptoms of depression, and one cm maternal scalp hair was collected and analyzed for cortisol concentrations. Multiple regression analyses did not show depressive symptoms as a predictor for HCC in our selection of pregnant women, while gestational age was significantly related. In conclusion, our study indicated that symptoms of depression during pregnancy did not predict HCC, but further studies of clinically depressed, pregnant women using gestational age as an adjustment variable are warranted.

  Anxiety disorders and Attention Deficit / Hyperactivity Disorder (ADHD) develop before school age, but little is known about early developmental pathways. Here we test two hypotheses: first, that early signs of anxiety and ADHD at 18 months predict symptoms of anxiety and ADHD at age 3½ years; second, that emotional dysregulation at 18 months predicts the outcome of co-occurring anxiety and ADHD at age 3½ years. The study was part of the prospective Norwegian Mother and Child Cohort Study (MoBa) at the Norwegian Institute of Public Health. The 628 participants were clinically assessed at 3½ years. Questionnaire data collected at 18 months were categorized into early behavioural scales of anxiety, ADHD, and emotional dysregulation. We investigated continuity in features of anxiety and ADHD from 18 months to 3½ years of age through logistic regression analyses. Anxiety symptoms at 3½ years were predicted by early signs of anxiety (Odds ratio [OR] = 1.41, CI = 1.15-1.73) and emotional dysregulation (OR = 1.33, CI = 1.15-1.54). ADHD symptoms at 3½ years were predicted by early signs of ADHD (OR = 1.51, CI = 1.30-1.76) and emotional dysregulation (OR = 1.31, CI = 1.13-1.51). Co-occurring Anxiety and ADHD symptoms at 3½ years were predicted by early signs of anxiety (OR = 1.43, CI = 1.13-1.84), ADHD (OR = 1.30, CI = 1.11-1.54), and emotional dysregulation (OR = 1.34, CI = 1.13-1.58). We conclude that there were modest continuities in features of anxiety and ADHD through early preschool years, while emotional dysregulation at age 18 months was associated with symptoms of anxiety, ADHD, and co-occurring anxiety and ADHD at age 3 ½ years.
