Abstract

Background:Blood pressure (BP) is an essential indicator for human health and is known to be greatly influenced by lifestyle factors, like activity and sleep factors. However, the degree of impact of each lifestyle factor on BP is unknown and may vary between individuals. Our goal is to investigate the relationships between BP and lifestyle factors and provide personalized and precise recommendations to improve BP, as opposed to the current practice of general lifestyle recommendations.Method:Our proposed system consists of automated data collection using home BP monitors and wearable activity trackers and feature engineering techniques to address time-series data and enhance interpretability. We propose Random Forest with Shapley-Value-based Feature Selection to offer personalized BP modeling and top lifestyle factor identification, and subsequent generation of precise recommendations based on the top factors.Result:In collaboration with UC San Diego Health and Altman Clinical and Translational Research Institute, we performed a clinical study, applying our system to 25 patients with elevated BP or stage I hypertension for three consecutive months. Our study results validate our system’s ability to provide accurate personalized BP models and identify the top features which can vary greatly between individuals. We also validate the effectiveness of personalized recommendations in a randomized controlled experiment. After receiving recommendations, the subjects in the experimental group decreased their BPs by 3.8 and 2.3 for systolic and diastolic BP, compared to the decrease of 0.3 and 0.9 for the subjects without recommendations.Conclusion:The study demonstrates the potential of using wearables and machine learning to develop personalized models and precise lifestyle recommendations to improve BP.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • All personalized intervention studies use predictive models based on multi-subject data.

    “Yet, of note, all of these personalized intervention studies use predictive models based on multi-subject data.”

    From Personalized machine learning guided intervention for optimizing lifestyle behaviors in depression: a pilot study (2026) · cites this paper as [23]

    The Results and Discussion, under “Experiment Setting,” says each person’s blood-pressure–lifestyle model was trained only on that person’s data. The Conclusion also describes personalized recommendations based on an individual model, making this study a counterexample to the claim that all such studies use models trained on multi-subject data. (LLM, conf=0.92)

    Checked by a reasoning model — may be wrong.

  • Personalizing treatment across multiple fields of healthcare leads to higher treatment adherence and improved satisfaction.

    “Studies across multiple fields of healthcare have shown that personalizing treatment leads to higher treatment adherence as well as improved satisfaction [20–23].”

    From Personalized machine learning guided intervention for optimizing lifestyle behaviors in depression: a pilot study (2026) · cites this paper as [23]

    The Conclusion reports improved blood pressure after personalized lifestyle recommendations, not higher treatment adherence or satisfaction. The Results and Discussion discusses participant drop-off and engagement as limitations but does not report either claimed outcome. Searches for adherence and satisfaction found no supporting passage, and the study addresses blood pressure rather than multiple healthcare fields. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
