Abstract

Objective

Two decades of research has examined within-person associations between negative emotion states and ambulatory blood pressure (ABP) using ecological momentary assessment (EMA), but no meta-analysis has been conducted. We conducted this systematic review and meta-analysis to quantify the magnitude of this association and identify moderators, review strengths and weaknesses in conceptual and measurement approaches, and provide recommendations.

Methods

We searched databases (PsycINFO, PubMed), identified 15 studies, and obtained data from 13 studies (n = 2511; 142,307 observations).

Results

Random-effects meta-analyses demonstrated small effect r values between momentary negative emotions and systolic ABP (r = 0.06) and diastolic ABP (r = 0.05; p values < .001). Meta-regressions found that effects were larger among studies focused on anxiety, multidimensional negative emotions, predominantly female samples, or less observations of each participant (p values from .003 to .049). A qualitative review found that few studies examined moderators contributing to the substantial interindividual differences in this association.

Conclusions

The small association between momentary negative emotion and ABP extends laboratory findings on the association between the experiential and physiological aspects of emotion to the daily, natural emotional experiences of individuals. This literature could be strengthened by determining interindividual and intraindividual moderators of this association (e.g., trait negative emotion and state positive emotion), examining differential associations of different negative emotions with ABP, and standardizing EMA protocols. Although the effect is small, to the extent that repeated emotion-related cardiovascular reactivity may contribute to cardiovascular disease risk, identifying daily life triggers of emotion is important.
