Background: An aging population and required hypertension control are global concerns that burden the healthcare system. Text messaging interventions have been developed to support hypertension management, but their effects on the older population are unknown. Objectives: This review aimed to identify the effects of a text messaging intervention on hypertension management among older adults. Methods: Four English and two Chinese databases with randomized controlled trials published between January 2010 and December 2020 were searched. The mean age of the participants was 60 years or above. Participants were also diagnosed with hypertension. The Cochrane risk-of-bias tool was used for the critical appraisal. Data in each study were extracted, and a meta-analysis was presented in terms of mean difference (MD) and standardized mean difference (SMD). Results: A total of 1670 records were screened, of which six were included in the final review. The intervention of the included studies lasted up to 6 months, and one-way text messaging was commonly used. Meta-analysis showed that a text messaging intervention significantly reduced systolic blood pressure (MD = −6.11, p <.01) but not diastolic blood pressure. Regarding medication adherence, a moderate effect was noted with the use of text messaging among older adults with hypertension (SMD = 0.65, p =.01). Linking Evidence to Action: A text messaging intervention can improve hypertension management among older adults. The standardized content of one-way text messaging is suggested to be delivered weekly.
