Abstract
BACKGROUND Older adults with postprandial hypotension (PPH) increase susceptibility to falls, syncope, stroke, acute cardiovascular diseases and even death. However, the prevalence of this condition varies significantly across studies. We aimed to determine the prevalence of PPH in older adults. METHODS Web of Science, PubMed, Cochrane Library, Embase and CINAHL were searched from their inception until February 2023. Search terms included 'postprandial period', 'hypotension' and 'postprandial hypotension'. Eligible studies were assessed using the Joanna Briggs Institute tool. Meta-analyses were performed among similar selected studies. RESULTS Thirteen eligible studies were included, and data from 3,021 participants were pooled. The meta-analysis revealed a PPH prevalence of 40.5% [95% confidence interval (CI): 0.290-0.519] in older adults, and this was prevalent in the community (32.8%, 95% CI: 0.078-0.647, n = 1,594), long-term healthcare facility (39.4%, 95% CI: 0.254-0.610, n = 1,062) and geriatrics department of hospitals (49.3%, 95% CI: 0.357-0.630, n = 365). The pooled results showed significant heterogeneity (I2 > 90%), partially related to the different ages, sex, pre-prandial systolic blood pressure levels of participants, or the different criteria and methodology used to diagnose PPH. CONCLUSIONS PPH is a prevalent condition in older adults. Further research is needed to confirm this result, and priority should be given to establishing international consensus on PPH diagnostic criteria and designing its diagnostic procedure.

Postprandial Hypotension and Impaired Postprandial Sustained and Selective Attention in Older Inpatients: Is There a Link? J Am Med Dir Assoc 2023; 24:1082-1087.e2. [PMID: 37121263 DOI: 10.1016/j.jamda.2023.03.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/14/2023] [Accepted: 03/16/2023] [Indexed: 05/02/2023]
Abstract
OBJECTIVES The study aimed to investigate the prevalence of postprandial hypotension (PPH) in older inpatients, to verify the overall postprandial behavior of blood pressure and attentional performances, and to explore the overall associations between blood pressure (including PPH) and attentional performances. Eventually, we aimed to investigate differences on PPH, blood pressure values and attentional performances based on the subjects' frailty status. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS A sample of older inpatients at the Geriatric Unit of the University Hospital of Messina (Italy). METHODS Basal, preprandial, and postprandial blood pressures (75 minutes after the meal) were measured for each patient; PPH was detected according to its empirical definition. Global cognitive functioning, and sustained and selective attention were assessed; a 46-item Frailty Index was calculated. RESULTS The sample consisted of 112 inpatients (54 females), with a mean age of 80.9 years. The prevalence of PPH was 30.4%; in the postprandial window, a reduction in blood pressure between 10 and 20 mm Hg and a reduction of >20 mm Hg were reported by 27.1% and 29.9% of inpatients, respectively. In the postprandial evaluation, sustained and selective attention markedly decreased. No significant associations were found between PPH occurrence and the postprandial dip of attentional performances, and no significant cognitive differences were found between inpatients with and without PPH. On the other hand, reduced postprandial attentional performances were associated especially with preprandial lower systolic and diastolic blood pressure values. Ultimately, no significant differences in PPH occurrence were found between frail and nonfrail inpatients; frail inpatients significantly exhibited also an overall lower cognitive functioning. CONCLUSIONS AND IMPLICATIONS In our sample, PPH and impaired postprandial attentional performances were not associated, even though this association deserves further investigation. In hospitalized older adults, the accurate management of blood pressure levels appears relevant, because we evidenced that low blood pressure (especially preprandial) was associated with poor attentional functioning. Although the plausible occurrence of several interfering and confounder factors was observed in an acute care setting, we consider that the screening of attentional functioning among hospitalized older patients could be helpful.

Glycemic Index Versus Wheat Fiber on Arterial Wall Damage in Diabetes: A Randomized Controlled Trial. Diabetes Care 2022; 45:2862-2870. [PMID: 36326712 PMCID: PMC9862401 DOI: 10.2337/dc22-1028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 09/25/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE High cereal fiber and low-glycemic index (GI) diets are associated with reduced cardiovascular disease (CVD) risk in cohort studies. Clinical trial evidence on event incidence is lacking. Therefore, to make trial outcomes more directly relevant to CVD, we compared the effect on carotid plaque development in diabetes of a low-GI diet versus a whole-grain wheat-fiber diet. RESEARCH DESIGN AND METHODS The study randomized 169 men and women with well-controlled type 2 diabetes to counseling on a low GI-diet or whole-grain wheat-fiber diet for 3 years. Change in carotid vessel wall volume (VWV) (prespecified primary end point) was assessed by MRI as an indication of arterial damage. RESULTS Of 169 randomized participants, 134 completed the study. No treatment differences were seen in VWV. However, on the whole-grain wheat-fiber diet, VWV increased significantly from baseline, 23 mm3 (95% CI 4, 41; P = 0.016), but not on the low-GI diet, 8 mm3 (95% CI -10, 26; P = 0.381). The low-GI diet resulted in preservation of renal function, as estimated glomerular filtration rate, compared with the reduction following the wheat-fiber diet. HbA1c was modestly reduced over the first 9 months in the intention-to-treat analysis and extended with greater compliance to 15 months in the per-protocol analysis. CONCLUSIONS Since the low-GI diet was similar to the whole-grain wheat-fiber diet recommended for cardiovascular risk reduction, the low-GI diet may also be effective for CVD risk reduction.
