Associations of crying, sleeping, and feeding problems in early childhood and perceived social support with emotional disorders in adulthood

Early childhood multiple or persistent regulatory problems and diurnal salivary cortisol in young adulthood

BACKGROUND

Early childhood multiple or persistent regulatory problems (RPs; crying, sleeping, or feeding problems) have been associated with a risk of behavioural problems in young adulthood. It has been suggested that this may be due to the possible influence of early RPs on the functioning of the hypothalamic-pituitary-adrenal (HPA) axis. However, associations between early RPs and HPA-axis activity in young adulthood remain unexplored. Thus, the aim of the current study was to investigate whether early childhood multiple or persistent RPs are associated with diurnal salivary cortisol in young adulthood.

METHODS

At the ages of 5, 20 and 56 months, RPs of 308 children from the Arvo Ylppö Longitudinal Study were assessed via standardized parental interviews and neurological assessments. Multiple RPs were defined as two or three RPs at the age of 5 months and persistent RPs as at least one RP at 5, 20 and 56 months. At the mean age of 25.4 years (SD= 0.6), the participants donated saliva samples for cortisol at awakening, 15 and 30 min thereafter, 10:30 am, at noon, 5:30 pm, and at bedtime during one day. We used mixed model regressions, and generalized linear models for testing the associations, controlling for important covariates.

RESULTS

Of the 308 children, 61 (19.8%) had multiple or persistent RPs in early childhood: 38 had multiple, and 27 had persistent RPs. Persistent RPs were associated with significantly higher cortisol peak and output in the waking period, and cortisol awakening response. On the other hand, multiple RPs were not associated with salivary cortisol.

CONCLUSION

Children displaying persistent RPs throughout early childhood show, over two decades later, increased HPA axis activity in response to awakening stress. This may be one physiological mechanism linking early childhood RPs to adulthood behavioural outcomes.

Shame, fear of compassion, self-criticism, and self-reassurance mediate the effect of early life events on emotional disorders among male prisoners: A structural equation modeling analysis

BACKGROUND

Early negative experiences in childhood are potent predictors of criminal behavior in youth and adulthood. This study aimed to identify the mediation effects of Shame, Fear of Compassion, Self-criticism, and Self-reassurance on the effect of Early Life Events on Emotional Disorders.

METHOD

This cross-sectional study was conducted among 368 male prisoners (Mean age: 33.26 ± 8.41 years) with convenient sampling method, from Ilam, Iran. A set of self-reported instruments were used for data collection. The ultimate model was constructed using structural equation modeling after confirming the construct validity of the measures via confirmatory factor analysis.

RESULTS

Shame, fear of compassion, self-criticism, and self-reassurance significantly mediated the relationship between Early Life Events and emotional disorders. The mediating effect accounted for 77 % of the total effect in the mediating model. According to Pearson's correlation, a positive and significant relationship existed between early life events and self-criticism, shame, fear of compassion and emotional disorders (P < .001). In conclusion, the presented model has an appropriate and acceptable fit, as evidenced by the results of the chi-square test (χ2 = 48.067, p < .001) and other relevant fit indices. However, self-reassurance's mediating role was insignificant (P > .05).

CONCLUSIONS

The present results showed that shame, fear of compassion, and self-criticism are important mediators in the relationship between early life events and emotional disorders among male prisoners. So, it is necessary to develop related protocols to increase the mental health of prisoners.
