Background/objectives: Negative experiences (NEs) have been shown to result in an increased stress response, as indicated by blood pressure, at the subsequent donation. This response might be influenced by how the donor rates the donation in terms of importance and pleasantness [affective attitude (AA)/cognitive attitude (CA)] or by anxiety about donating blood. We investigated the effect of AA/CA/anxiety on the impact of NEs on pre-donation blood pressure (pd-BP) in the subsequent donation. Materials/methods: pd-BP at visit 3 was compared between donors with and without a history of NEs during or after their first two visits (visit 1: medical check, visit 2: first donation). The effect of AA/CA/anxiety (measured 1 month prior to visit 1 on a 7-point scale) on visit 3 pd-BP was explored using linear regression and interaction analyses. Analyses were stratified for gender, age and pd-BP at visit 1, which were taken into account as confounders. Results: In 1106 first-time blood donors (70% female), 632 donors (57% of total) indicated an NE at their first donation. Mean scores for AA/CA/anxiety were 5·2/6·5/2·2 (men without NE), 4·8/6·3/3·0 (men with NE), 5·2/6·6/2·6 (women without NE) and 4·8/6·6/3·2 (women with NE). No significant associations were found for NE and pd-BP at visit 3 after adjusting for confounding. Of 48 interaction effects, four were significant, but effects were small and inconsistent. Conclusion: In donors who had had negative experiences during their first donation, anxiety and attitude to donation did not influence their pre-donation blood pressure at their subsequent visit.
