Abstract: Objectives: The aim of this study was to investigate the effects of guar gum on postprandial blood pressure in older people. Design: A randomized, double-blind, placebo-controlled, cross-over design. Setting: Community senior centers in B city, South Korea. Participants: Twenty-two older female adults aged 67 to 88 with postprandial hypotension. Intervention: The participants were randomly assigned to guar gum (semi-fluid food with 9 gram) or placebo intervention during the first treatment phase. After a washout period of 1 week, the two interventions were switched to the other in the second treatment phase. Measurements: Blood pressure was measured during both phases before having a meal and every 15 minutes during 120 minutes after a meal with automated sphygmomanometer. Results: Change in systolic blood pressure (SBP) over time was significantly different between guar gum and placebo groups (F=4.07, p=0.001). Compared with placebo group, guar gum group had significantly low prevalence of postprandial hypotension (PPH) (guar gum group=18.2% vs. placebo group=72.7%; χ2=13.20, p.05. To investigate the effect of experimental intervention, the serial measurements of blood pressure after a meal over time between the experimental and control groups were analyzed by

At 45, 60, and 75 minutes, DBP was significantly lower than at baseline in the control group, but no significant changes were noted in DBP in the experimental group during the 120 minutes following the meal compared with baseline (Table 2, Figure 2-B).
