Abstract
Diabetic Mellitus (DM) is a widespread chronic disease around the world, among which type 2 DM (T2DM) shared the majority. It caused multiple severe complications and consequently a high mortality rate. DM complications overwhelm jeopardize the patient’s quality of life. In response to the threats of such complications, some nutraceuticals were developed, including the highly praised bitter melon peptide (BMP). This study aims to apply the structural equation model in HBM. A theoretical model had been developed on the health belief model (HBM), and to test with the structural equation model (SEM) technique to examine the fitness of the theory and the data gathered in this research. A structural questionnaire was developed and used to collect 292 valid responses from DM patients. The SEM results indicated the fitness of the theory and the data were acceptable. Perceived susceptibility of DM complications and perceived benefits of nutraceutical were major predictors of intake behavior, and the association of perceived benefits and behavior was mediated by the patient’s self-efficacy on nutraceutical intake behavior.
Highlights
Despite that Diabetic Mellitus (DM) is a horrible health problem, it can be manageable, especially for those caused mainly by dietary and living style, so called type 2 DM

Model fit indicators determines whether the sample data fit the structural equation model proposed
Summary
Despite that DM is a horrible health problem, it can be manageable, especially for those caused mainly by dietary and living style, so called type 2 DM. Severe DM complications, such as such as kidney diseases, neurological, circulatory, oral, ophthalmic and skin complications, and other unspecified diabetic conditions can jeopardize the quality of life of the patients and their families. It is generally a pharmaceutical alternative that claims to be beneficial to human’s physiological status (Sarris et al, 2016). In addition to the basic nutritional value, nutraceutical is a product that generally extracted or derived from human’s food sources to provide extra health benefits. Nutraceutical products can be found in the market to claim to prevent chronic diseases, improve health, delay the aging process, increase life expectancy, or support the structure or function of the body (Sarkar, 2007; Sarris et al, 2016)
