Abstract
AbstractBackgroundOlder adults frequently suffer from postprandial hypotension, associated with an increased risk of falls, syncope, acute cardiovascular and cerebrovascular diseases, and even death. Researchers use non‐pharmacological interventions, but related literature is dispersed and lacks a latest summary.ObjectiveThe aim of this study was to map and examine non‐pharmacological interventions currently employed to assist older adults with postprandial hypotension and lay a solid foundation for future studies.MethodsThis study adhered to the JBI methodology for scoping reviews and preferred reporting items for systematic reviews and meta‐analyses extension for scoping reviews. PubMed, Web of Science, Embase, Cochrane Library, CINAHL, SCOPUS, Chinese Biomedical Journal, China National Knowledge Infrastructure, VIP and WAN FANG Data were retrieved from their inception to 1 August 2022.ResultsTwo randomized controlled trials and seven quasi‐experimental studies were included. Small meals, exercise interventions, fibre with meals, green tea and water therapy have been reported to prevent postprandial hypotension effectively; however, position changes have been reported to have no impact on postprandial blood pressure decrease. Additionally, the blood pressure determination methods and test meals may affect observed trial effects.ConclusionLarge samples and long‐term follow‐up studies are needed to prove the efficacy and safety of existing non‐pharmacological interventions. Future studies should develop a BP determination method based on the postprandial BP decline trajectory induced by a given test meal to improve the reliability of study results.Relevance to Clinical PracticeThis review broadly summarizes existing studies on developing and validating non‐pharmacological interventions for older adults with postprandial hypotension. It also analyses special factors that may influence the trial effects. This may provide a useful reference for future research.
