Abstract
This study examines relations between children's salivary interleukin-6 (IL-6) and secretory immunoglobulin A (SIgA) and mental health. Child sex was considered as a moderator of relations. Data were from 329 normally developing children (M age = 9.85. years; SD = .98. years); 67% of children were European American and 33% were African American. Saliva samples were obtained during the afternoon and assayed for SIgA and IL-6. Parents completed questionnaire measures of child internalizing and externalizing symptoms, and children completed self-report measures of anxiety and depression. Structural equation models were fit to the data, and indicated that greater levels of salivary IL-6 and SIgA were associated with adjustment problems more strongly for girls than for boys.
