Abstract

PURPOSE
The purposes of this study were to identify the prevalence of postprandial hypotension (PPH) and risk factors for PPH in Korean elderly people. METHODS: A cross-sectional descriptive study was conducted with community dwelling and nursing home residents. The blood pressure of 162 adults aged 65 yr or older was measured before meal as a baseline and then at 15 min intervals from immediately after the meal through 90 min after the meal. Descriptive statistics and logistic regression with the SPSS WIN 14.0 program were used to analyze the data. RESULTS: The prevalence of PPH was 29% and the PPH occurred immediately after the meal continuously through 90 min after the meal. The biggest drop in systolic blood pressure occurred at 45 min after the meal. Risk factors for PPH were age, base line systolic blood pressure, and presence of cardiovascular disease. CONCLUSION: To prevent side effects of PPH such as falls and syncope, nurses should provide careful management of PPH and prohibit activities until at least 90 min after a meal. We also recommend that risk of PPH should be included in fall prevention guidelines for elderly people.
