Abstract
This research aimed to drive the utilization of the electronic personal health record
system for diabetes mellitus (DM) and hypertension (HT) in a pilot area. The study specifically
investigated nutritional literacy and health promotion behaviors related to blood sugar levels
and complications in diabetic patients, both before and after the implementation of the
health record system within the "Moh Promt" application, and applied the same approach to
hypertensive patients. The goal was to foster health literacy and develop recommendations
for improving the usability of the personal health record system. The study population
comprised 446 patients diagnosed with Type 2 Diabetes Mellitus and hypertension in
Bangrakam District, Phitsanulok Province. Data were collected using a structured interview
questionnaire composed of two parts: general information and assessed health literacy, with
reliability coefficients ranging from 0.77 to 0.94. Data were analyzed using descriptive statistics,
Paired Sample T-test, Unpaired T-test, Chi-square test, and multiple logistic regression analysis
via R program (version 4.5.1), with a p-value < 0.05 considered statistically significant. The
study found that diabetic patients utilizing the Mor Prom application showed a significant
reduction in blood glucose levels (from 156.0 mg/dL to 148.2 mg/dL) at the second data
collection point. The adjusted Odds Ratio (aOR) for achieving controlled blood glucose levels
(FBS 80–140 mg/dL) among app users compared to non-users was 0.73. Conversely, the appuser group's average blood glucose was slightly higher than the non-user group’s (148.2 vs.
146.1 mg/dL), potentially due to confounding variables such as BMI or disease duration. For
HT patients, both groups showed significant increases in health literacy scores, attributed to
standardized clinic education. App users had an aOR of 1.25 for controlled blood pressure but
this was not statistically significant, possibly because the app’s general advice mirrored the
clinic's existing guidance.
