Inflammatory reactivity to acute laboratory stress is thought to reflect individual differences in responsivity to environmental stressors and may confer future health risk. To characterize this response, we conducted a meta-analysis of 34 studies that measured circulating inflammatory markers and 15 studies that measured stimulated production of inflammatory markers before and after exposure to laboratory challenge. Results showed significant stress-related increases in circulating interleukin (IL)-1? (d = 0.66, p < 0.001), IL-6 (d = 0.35, p < 0.001), IL-10 (d = 0.69, p < 0.001), and tumor necrosis factor(TNF)-? (d = 0.28, p < 0.001), but not IL-1ra, IL-2, interferon-?, or C-reactive protein. There were sufficient data to assess the time course of IL-6, IL-1?, and TNF-? reactivity. IL-6 increased from baseline to measures taken 40–50, 60–75, 90, and 120 min following stress, with the largest effect at 90 min post-stress (d = 0.70, p < 0.001). IL-1? increased from baseline to 20–30, 40–50, and 60–70 min following stress, with the largest effect between 40 and 50 min post-stress (d = 0.73, p = 0.02). For TNF-?, there was a significant increase from baseline to 31–50 min post stress (d = 0.44, p = 0.01), but not at later times. There was no difference in magnitude of IL-6 reactivity as a function of type of stress (social-evaluative versus other). For stimulated inflammatory markers, results showed stress-related increases in IL-1? when measured 20–120 min post-stress (d = 1.09, p < 0.001), and in IL-4 and interferon-? when measured 0–10 min post stressor (d = ?0.42, p < 0.001 and d = 0.47, p < 0.001). These results extend findings from a prior meta-analysis (Steptoe et al., 2007) to show reliable increases in circulating IL-6, IL-1?, IL-10 and TNF-? and stimulated IL-1?, IL-4 and interferon-? in response to acute stress. It is possible that these responses contribute to associations between exposure to life challenges and vulnerability to inflammatory disease.
