Abstract

Hypertension and obesity represent significant global public health challenges requiring innovative educational interventions. The Si-hypertension and obesity information system (HIPO) application was developed as a context-specific digital health education medium targeting Indonesian community health center populations, distinguishing it from existing generic mHealth tools by integrating comorbid hypertension-obesity education within a culturally appropriate single platform. This study aimed to assess the content validity of the Si-HIPO application through expert and respondent validation. A quantitative descriptive cross-sectional design was employed at Sibela Community Health Center, Surakarta, Indonesia. Expert validation involved two assessors using Aiken's V coefficient methodology, while respondent validation included 66 participants with hypertension and overweight/obesity. Respondent characteristics revealed predominantly female participants (60.61%), aged > 40 years (39.39%), with stage 2 hypertension (51.52%) and obesity (59.09%). Respondent evaluation demonstrated 72.73% positive acceptance. Expert validation yielded high validity coefficients for nine of ten items (V = 0.802-0.833), with one item showing moderate validity (V = 0.667). The aggregated validity coefficient was 0.802, indicating high overall content validity. The Si-HIPO application demonstrates strong content validity and user acceptability as an educational medium for hypertension and obesity management. However, further effectiveness testing through experimental or quasi-experimental designs is warranted before implementation in clinical practice.

Abstract

Hypertension in obese patients requires comprehensive management through enhanced health literacy. Android-based applications represent a promising innovation for improving hypertension control literacy. To analyze the effectiveness of the Android-based hypertension and obesity information system (HIPO) application in improving hypertension control literacy among obese patients. This quasi-experimental study employed a one-group pretest-posttest design without a control group, conducted at Sibela Community Health Center, Surakarta, from June to December 2025. Seventy-six respondents were selected through purposive sampling, meeting criteria of primary hypertension (≥ 140/90 mmHg) and BMI ≥ 25 kg/m². The intervention involved four weeks of HIPO application use. Data were analyzed using the Wilcoxon Signed Rank Test. Respondents were predominantly female (67.11%), aged 46-55 years (31.58%), with a genetic predisposition to hypertension (57.89%). Systolic blood pressure significantly decreased from 159.53 ± 14.19 to 144.48 ± 11.44 mmHg (p < 0.001), and diastolic from 95.20 ± 6.55 to 88.50 ± 4.58 mmHg (p < 0.001). Good knowledge increased from 35.53% to 55.26%, and good hypertension control increased from 35.53% to 61.84%. The HIPO application significantly improved blood pressure, knowledge, and hypertension control. However, the absence of a control group limits causal inference. This application may serve as a supplementary educational tool in primary healthcare chronic disease management programs.
