An Analysis of Determinants Affecting the Utilization of Integrated Non-Communicable Disease Service Posts (Posbindu PTM) in the Ulee Kareng Public Health Center, Banda Aceh City: A Health Belief Model Approach

Non-communicable diseases (NCDs) are the leading cause of mortality worldwide, including in Indonesia, with a growing prevalence particularly in low- and middle-income countries. Banda Aceh City has recorded increasing rates of hypertension and diabetes mellitus. However, the utilization of early detection services through the Integrated Non-Communicable Disease Service Post (Posbindu PTM) remains suboptimal, with only 32% of the target population visiting the service at Ulee Kareng Public Health Center—far below the national target of 100%. This low utilization rate is presumed to be linked to public perceptions regarding disease risk and the importance of routine health screenings. This study aimed to examine the determinants influencing the utilization of Posbindu PTM using the Health Belief Model (HBM), which focuses on perceived susceptibility, severity, benefits, and barriers to health behavior. This study employed an observational analytic design with a cross-sectional approach. The population comprised individuals aged 15–59 years living in the catchment area of the Ulee Kareng Public Health Center in 2024. A total of 375 respondents were selected as the study sample. The data were analyzed using the Partial Least Squares (PLS) method with SmartPLS version 4.0. The findings indicated that perceived susceptibility, perceived severity, perceived benefits, and self-efficacy were significantly associated with the utilization of Posbindu PTM. In contrast, family support, support from health cadres and health workers, peer support, and perceived barriers showed no significant association. The most influential determinant was perceived benefits. Interventions that enhance individuals' perceived benefits are recommended for government initiatives aimed at increasing the utilization of Posbindu PTM services.
