Abstract
Objective: This study aimed to evaluate the prevalence of OH and orthostatic intolerance (OI), and associated factors of OH among older persons.
Design: The study was a cross-sectional analytic study of 284 participants aged 60 years or older who visited the outpatient clinic, Phramongkutklao Hospital.
Materials and Methods: Face-to-face interviews were conducted andOH was measured by standard method. The prevalence of OH and OI were described by the percentage. Factors associated with OH were analyzed by multivariate logistic regression analysis (p-value < 0.05).
Results:The prevalence of OH and OI was 17.25% and 58.45%, respectively. OH, was found highest in participants aged 80 years and above (adjust OR 5.27 (95% CI; 1.65-16.83, p = 0.005)) compared to those aged 70-79 years (adjust OR 2.82 (95% CI; 1.19-6.72, p = 0.019)). Participants with polypharmacy were more likely to have OH (adjust OR 3.66 (95% CI; 1.52-8.79, P = 0.004)) than those with non-polypharmacy. Additionally, OH was also associated with gait and postural instability (adjust OR: 3.92(95% CI; 1.70-9.05, p = 0.001)), and poor vision (adjust OR: 4.38 (95% CI; 1.92 – 10.00, p = 0.001)).
Conclusion:About one in six older adults was effected by OH, which was associated with multiple factor. Some of these factors are modifiable and can be addressed to reduce the incidence of OH.
