- BackgroundUnderstanding how child maltreatment is passed down from one generation to the next is crucial for the development of intervention and prevention strategies that may break the cycle of child maltreatment. Changes in emotion recognition due to childhood maltreatment have repeatedly been found, and may underly the intergenerational transmission of child maltreatment.ObjectiveIn this study we, therefore, examined whether the ability to recognize emotions plays a role in the intergenerational transmission of child abuse and neglect.Participants and settingA total of 250 parents (104 males, 146 females) were included that participated in a three-generation family study.MethodParticipants completed an emotion recognition task in which they were presented with series of photographs that depicted the unfolding of facial expressions from neutrality to the peak emotions anger, fear, happiness, and sadness. Multi-informant measures were used to examine experienced and perpetrated child maltreatment.ResultsA history of abuse, but not neglect, predicted a shorter reaction time to identify fear and anger. In addition, parents who showed higher levels of neglectful behavior made more errors in identifying fear, whereas parents who showed higher levels of abusive behavior made more errors in identifying anger. Emotion recognition did not mediate the association between experienced and perpetrated child maltreatment.ConclusionsFindings highlight the importance of distinguishing between abuse and neglect when investigating the precursors and sequalae of child maltreatment. In addition, the effectiveness of interventions that aim to break the cycle of abuse and neglect could be improved by better addressing the specific problems with emotion processing of abusive and neglectful parents.

- BACKGROUND: In adults, cortisol levels show a pronounced 24-hour rhythm with a peak in the early morning. It is unknown at what age this early-morning peak in cortisol emerges during infancy, hampering the establishment of optimal dosing regimens for hydrocortisone replacement therapy in infants with an inborn form of adrenal insufficiency. Therefore, we aimed to characterize daily variation in salivary cortisol concentration across the first year of life.METHODS: We conducted a systematic review followed by an individual participant data meta-analysis of studies reporting on spontaneous (i.e., not stress induced) salivary cortisol concentrations in healthy infants aged 0-1 year. A one-stage approach using linear mixed-effects modelling was used to determine the interaction between age and time of day on cortisol concentrations.FINDINGS: Through the systematic review, 54 eligible publications were identified, reporting on 29,177 cortisol observations. Individual participant data were obtained from 15 study cohorts, combining 17,079 cortisol measurements from 1,904 infants. The morning/evening cortisol ratio increased significantly from 1.7 (95% CI: 1.3-2.1) at birth to 3.7 (95% CI: 3.0-4.5) at 6-9 months (p < 0.0001). Cosinor analysis using all available data revealed the gradual emergence of a 24-hour rhythm during infancy.INTERPRETATION: The early-morning peak in cortisol secretion gradually emerges from birth onwards to form a stable morning/evening ratio from age 6-9 months. This might have implications for hydrocortisone replacement therapy in infants with an inborn form of adrenal insufficiency.
