Prevalence and correlates of use of digital technology for managing hypertension among older adults.

Journal Article (Journal Article)

Hypertension is prevalent among older adults (60 years and above), but control of blood pressure (BP) remains suboptimal. While there is increasing interest in using digital technology for managing hypertension, information about the extent and potential correlates of such use among older adults remains scant. We assessed the prevalence and correlates of the use of digital technology for managing hypertension among older adults with hypertension. We also investigated if the use of digital technology was associated with BP or hypertension control. The use of digital technology (internet or digital apps) for information about or managing BP or hypertension was assessed among 1729 older adults diagnosed with hypertension participating in a national survey in Singapore. Regression analysis was used to assess the correlates (based on the Unified Theory of Use and Acceptance of Technology), and whether such use was associated with hypertension control or BP values. Digital technology for managing hypertension was used by 7.1% of older adults with hypertension. Those of higher age and with limitations in one or more activities or instrumental activities of daily living were less likely, while those with secondary education and above, and with stronger social network were more likely to use digital technology. There was no association between the use of digital technology and hypertension control. While users of digital technology had lower systolic (by 2.1 mmHg, adjusted p value = 0.12) and diastolic (by 1.6 mmHg, adjusted p value = 0.13) BP than non-users, the differences were not statistically significant. Given its low prevalence, there is potential for increased use of digital technology for managing hypertension among older adults with hypertension in Singapore. Initiatives to increase digital health use should target specific older adult subgroups.
