Abstract

This cross-sectional study research aims to test a causal relationship structure model of dietary behavior to control blood glucose levels of type 2 diabetes mellitus patients by developing elements from the theory of planned behavior and the self-efficacy theory. The study group consisted of 350 people with type 2 diabetes mellitus, aged between 40-59, who received medical care at Pathum Thani Hospital, Pathum Thani Province. Participants were selected by simple random sampling with a computer program to write random commands from random numbers. The instrument used for the study consisted of demographic data, a questionnaire to investigate the perceived behavioral control, intention to perform the behavior, self-efficacy to diet, and dietary behavior to control blood glucose levels questionnaire. Data were analyzed with descriptive statistics and a computer program AMOS to analyze structural equation models (SEM).
 
The study results revealed that a causal relationship structure model of dietary behavior to control blood glucose levels of type 2 diabetes mellitus patients fit with the empirical data and could explain 83% of the variance in dietary behavior to control blood glucose levels affecting blood sugar levels. Dietary behavior to control blood glucose levels had a direct negative effect on glycated hemoglobin levels (HbA1c) gif.latex?(\beta&space;=&space;-0.91,&space;p<.05). The perceived behavioral control, self-efficacy to diet, and behavioral intention had a positive direct effect on dietary behavior to control blood glucose levels respectively gif.latex?(\beta&space;=&space;0.55,&space;p<.05;&space;\beta&space;=&space;0.50,&space;p<.05;&space;\beta&space;=&space;0.31,&space;p<.05). In addition, variables with an indirect effect on dietary behavior to control blood glucose levels through behavioral intention were self-efficacy in diet and behavioral control respectively gif.latex?(\beta&space;=&space;0.30,&space;p<.05;&space;\beta&space;=&space;0.27,&space;p<.05).
 
The study concludes that the perceived behavioral control, self-efficacy to diet, and intention to perform the behavior directly affected dietary behavior to control blood glucose levels of type 2 diabetes mellitus patients.
