Objective: Acute inflammation-induced sickness behavior involves changes in social behavior that are believed to promote recovery. Whether chronic inflammation can influence social behaviors in ways that promote recovery is unknown. In a sample of mothers of a child with cancer, this report explores the relationship between inflammation that accompanies the stress of diagnosis and changes in social network, cancer-related stress, and inflammation across one year. Three hypotheses were tested, that (1) initial stress would associate with initial inflammation, (2) initial inflammation would predict social changes over time, and (3) social changes over time would buffer stress and inflammation over time. Methods: Cancer-related stress (Impact of Events Scale), social network (social roles and contacts from the Social Network Inventory), and systemic inflammation (circulating IL-6) were assessed in 120 mothers three times after their child’s cancer diagnosis: following diagnosis (T1), 6-month follow-up (T2), and 12-month follow-up (T3). Results: Consistent with predictions, greater cancer-related stress following diagnosis (T1) was associated with higher IL-6 following diagnosis (T1; b=.014, p=.008). In turn, higher IL-6 following diagnosis (T1) was associated with a decrease in social roles over time (T1-->T3; B=-.030, p=.041), particularly peripheral social roles. Finally, dropping social roles over time (T1-->T3) was associated with decreases in cancer-related stress (B=21.83, p=.040) and slower increases in IL-6 (B=.940, p=.036) over time.Conclusions: This study provides a first indication that chronic stress-related systemic inflammation may predict changes in social behavior that associate with stress recovery and slower increases in inflammation in the year following a major life stressor.
