Abstract

Background: Amid global ageing, managing chronic diseases in older adults has become a significant public health concern. Using blood pressure monitors as an example, this study systematically examines the key factors influencing blood pressure monitoring among elderly users and their interactions, offering theoretical support for the design of health products for older people.

Methods: First, an interview outline was developed to invite elderly individuals for interviews; grounded theory was used to organise the interview data; then, a Structural Equation Modeling ( SEM ) theoretical framework was established by integrating relevant literature. Subsequently, a questionnaire was distributed, and descriptive statistics, data distribution analysis, and exploratory factor analysis were conducted on the questionnaire data. Finally, the data were imported into the SEM model, and SEM was used to quantify the influence weights between dimensions. Artificial Neural Network ( ANN ) was further employed to predict the nonlinear relationships between dimensions.

Results: All SEM model assumptions were confirmed. Both SEM and ANN analyses showed that the factors most influencing elderly individuals' satisfaction with blood pressure monitors were Physiological factor (0.237, 1.00) and Adult children factors (0.188, 0.85), followed by Product configuration (0.149, 0.92), Interaction factors (0.149, 0.81), Psychological factor (0.149, 0.74), Personal factors (0.131, 0.85), and Social support (0.106, 0.62).

Conclusion: When designing blood pressure monitors, prioritise enhancing physiological adaptability features for elderly users, including key design elements such as enlarged interface fonts, bigger operation buttons, voice interaction functionality, and error-tolerant mechanisms, to significantly improve user satisfaction. This design approach can be applied to the development of other age-friendly medical products.

Notes for potential reviewers

  • Volunteering is not a guarantee that you will be asked to review. There are many reasons: reviewers must be qualified, there should be no conflicts of interest, a minimum of two reviewers have already accepted an invitation, etc.
  • This is NOT OPEN peer review. The review is single-blind, and all recommendations are sent privately to the Academic Editor handling the manuscript. All reviews are published and reviewers can choose to sign their reviews.
  • What happens after volunteering? It may be a few days before you receive an invitation to review with further instructions. You will need to accept the invitation to then become an official referee for the manuscript. If you do not receive an invitation it is for one of many possible reasons as noted above.
  • PeerJ does not judge submissions based on subjective measures such as novelty, impact or degree of advance. Effectively, reviewers are asked to comment on whether or not the submission is scientifically and technically sound and therefore deserves to join the scientific literature. Our Peer Review criteria can be found on the "Editorial Criteria" page - reviewers are specifically asked to comment on 3 broad areas: "Basic Reporting", "Experimental Design" and "Validity of the Findings".
  • Reviewers are expected to comment in a timely, professional, and constructive manner.
  • Until the article is published, reviewers must regard all information relating to the submission as strictly confidential.
  • When submitting a review, reviewers are given the option to "sign" their review (i.e. to associate their name with their comments). Otherwise, all review comments remain anonymous.
  • All reviews of published articles are published. This includes manuscript files, peer review comments, author rebuttals and revised materials.
  • Each time a decision is made by the Academic Editor, each reviewer will receive a copy of the Decision Letter (which will include the comments of all reviewers).
