Immediate and longitudinal effects of maltreatment on systemic inflammation in young children
Development and Psychopathology
Exposure to child maltreatment increases the risk for psychiatric and physical diseases. Inflammation has been proposed as a mechanism through which early adverse experiences become biologically embedded. However, most studies providing evidence for the link between early adverse exposures and inflammation have been retrospective or cross-sectional in design, or did not assess inflammation immediately after maltreatment in young children. In the present study we investigated the association between childhood maltreatment and salivary C-reactive protein (CRP) concentrations in a population of N = 173 children, 3–5 years of age, who were recruited in the immediate aftermath of maltreatment and followed-up longitudinally every 6 months over a period of 2 years. We found that the association between maltreatment and CRP concentrations was significantly moderated by child sex, such that in girls, CRP concentrations were higher in the maltreated compared to the control group, and this dif...
Childhood maltreatment and inflammatory markers: a systematic review
Acta psychiatrica Scandinavica, 2013
ObjectiveChildhood maltreatment (CM) has been associated with several diseases in adult life, including diabetes, obesity and mental disorders. Inflammatory conditions have been postulated as possible mediators of this relationship. The aim was to conduct a systematic review regarding the association between CM and inflammatory markers in adulthood.Childhood maltreatment (CM) has been associated with several diseases in adult life, including diabetes, obesity and mental disorders.

Increased levels of circulating CRP in individuals with a history of CM were the most robust finding among the studies. Data about anti-inflammatory mediators are still few and inconsistent.Twenty articles remained in the review after exclusion criteria were applied.

Associations between childhood maltreatment and inflammatory markers

Background Childhood maltreatment is one of the strongest predictors of adulthood depression and alterations to circulating levels of inflammatory markers is one putative mechanism mediating risk or resilience. Aims To determine the effects of childhood maltreatment on circulating levels of 41 inflammatory markers in healthy individuals and those with a major depressive disorder (MDD) diagnosis. Method We investigated the association of childhood maltreatment with levels of 41 inflammatory markers in two groups, 164 patients with MDD and 301 controls, using multiplex electrochemiluminescence methods applied to blood serum. Results Childhood maltreatment was not associated with altered inflammatory markers in either group after multiple testing correction. Body mass index (BMI) exerted strong effects on interleukin-6 and C-reactive protein levels in those with MDD. Conclusions Childhood maltreatment did not exert effects on inflammatory marker levels in either the participants with M...

Prior research has found inconsistent evidence regarding the association among childhood adversity, inflammation, and internalizing symptoms, perhaps because previous studies have yet to adequately integrate important factors such as the timing of the adversity, genetic variation, and other relevant processes such as neuroendocrine regulation. The aims of the present study were threefold: (a) to determine whether the effect of the timing of child maltreatment on C-reactive protein (CRP), an inflammatory marker, varies by CRP gene variation; (b) to explore whether links between salivary CRP and childhood internalizing symptoms depend on the presence and timing of maltreatment experiences; and (c) to investigate the role of CRP in the relations between child neuroendocrine regulation and internalizing symptoms and examine whether these associations are moderated by the presence and timing of child maltreatment. Participants included a sample of 267 maltreated and 222 nonmaltreated chi...
Association between early life adversity and inflammation during infancy
Developmental psychobiology, 2017
Early life adversity is associated with adult elevations of inflammatory markers such as circulating levels of C-reactive protein (CRP). Few studies have measured inflammation or its association with psychosocial stress during infancy. Existing evidence suggests that early adversity can embed itself into young children's biology with implications for lifelong development. This study examined the association between psychosocial stress and salivary CRP in infants. Early adversity in the form of socioeconomic disadvantage and maternal psychosocial stress were measured when infants were 17 months old. Resting state saliva samples were collected to assess CRP (pg/ml) levels via enzyme immunoassay. Results revealed that both socioeconomic disadvantage and maternal psychosocial stress were independently associated with higher infant CRP levels. These results raise questions about timing of exposure to adversity, and about the potentially lasting effects on inflammatory processes when ...
