Key result
Non-pharmacological interventions including small meals, exercise, fibre, green tea, and water therapy effectively prevented postprandial hypotension, while position changes had no impact.
Why the study?
Postprandial hypotension in older adults increases risks of falls, syncope, cardiovascular events, and death, but literature on non-pharmacological interventions is dispersed and lacks an updated summary.
Do non-pharmacological interventions prevent postprandial hypotension in older adults?
Systematic Review
Do non-pharmacological interventions prevent postprandial hypotension in older adults?
Non-pharmacological interventions such as small meals, exercise, fibre, green tea, and water therapy may effectively prevent postprandial hypotension in older adults, though larger long-term studies are needed.

Supports incorporating effective non-pharmacological interventions into postprandial hypotension management; confirms Level 1 evidence for lifestyle strategies.
BACKGROUND: Older 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. OBJECTIVE: The 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. METHODS: This 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. RESULTS: Two 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. CONCLUSION: Large 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 PRACTICE: This 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.

Huang et al. (2023) conducted a systematic review in postprandial hypotension. Non-pharmacological interventions was evaluated on postprandial blood pressure decrease. Non-pharmacological interventions including small meals, exercise, fibre, green tea, and water therapy effectively prevented postprandial hypotension, while position changes had no impact.
