Oral contraceptive use and increased plasma concentration of C-reactive protein

Abstract

We examined, in young adult women, the association between current low dose oral contraceptive (OC) use and plasma levels of C-reactive protein (CRP), an acute phase reactant predictive of cardiovascular disease risk. We conducted a cross-sectional analysis of 30 healthy, non-smoking, non-obese women (18 OC users and 12 nonusers) who were subjects in a randomized diet-controlled trial of the effects of soy intake on sex hormone metabolism. The study was sited at a university outpatient general clinical research center. Fasting plasma CRP levels were measured 4 times during 2 menstrual cycles (2 mid-follicular phase and 2 mid-luteal phase) using a high-sensitivity CRP assay. Differences between OC users and nonusers were examined by 3-way analysis of variance. Multiple regression was used to examine the relationship between OC use and CRP. There were no significant differences in baseline demographic characteristics between OC users and nonusers. Plasma CRP levels (mean +/- SE) were 2 times higher among OC users than among non-users (2.0 +/- 0.2 versus 0.9 +/- 0.3 mg/l, p<0.0001) independent of diet assignment, diet treatment order, and phase of the menstrual cycle. In a multivariate model, OC use predicted 32 percent of the variance in CRP levels (p<0.0001). As all CRP levels were within a previously established normal range, further study is indicated to establish the clinical significance of the observed elevated CRP levels in OC users.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
