Romantic relationship distress, gender, socioeconomic status, and inflammation: A preregistered report.

Poor quality romantic relationships increase risk for health problems; elevated systemic inflammation is one promising underlying mechanism. This registered report utilized data from 3 publicly available datasets with large sample sizes (Add Health, MIDUS, NSHAP) to test this possibility. An internal meta-analysis across all 3 studies determined that romantic relationship distress was unrelated to inflammation (assessed via C-Reactive Protein levels). In addition, this link was not moderated by gender, socioeconomic status (SES), or the combination of gender and SES.
