# Trust Components: An Analysis in The Development of Type 2 Diabetic Mellitus Mobile Application
## 1 Introduction  
### Mobile Health Application for Diabetes Mellitus  
Mobile health applications are software tools that help users monitor their health conditions via smartphones and tablets [1]. Their functionality ranges from simple diaries, medication reminders, and tracking health progress to more complex programs certified as medical devices by health authorities. Currently, mobile health applications with a large number of users have a high potential for improving healthcare [2]. The reliability of these applications remains in doubt, limiting their widespread adoption [3]. Extensive research on trust in technology and the role of user trust in the selection of various information technology (IT) artifacts have yet to be conducted [4].  
Diabetes mellitus is a genetically and clinically heterogeneous metabolic disorder characterized by carbohydrate tolerance loss [5]. Diabetes mellitus is clinically characterized by fasting and postprandial hyperglycemia, atherosclerosis, and microangiopathic vascular disease [6].  
Diabetes mellitus is classified into two types: type 1 and type 2 diabetes. Type 1 diabetes is characterized by the pancreas, the body's insulin factory, being unable or less able to produce insulin [7]. As a result, the body's insulin is lacking or not present at all, and sugar accumulates in the blood circulation because it cannot be transported into cells [8]. Type 2 diabetes mellitus (T2 DM) is the most common type [9]. The pancreas can still produce insulin in type 2 diabetes, but the quality of the insulin is poor, and it cannot properly function, causing blood glucose levels to rise [10]. Patients with this type of diabetes usually do not need additional insulin injections in their treatment but do need drugs that work to improve insulin function, lower glucose, improve sugar processing in the liver, and perform several alternative treatments for support [11]. Age, sex, family history, physical activity, and eating habits are the risk factors that have the greatest associationwith the incidence of type 2 diabetes mellitus (T2 DM) among the many factors that cause diabetes mellitus [12].  
All types of diabetes can cause many complications in the body and increase the risk of premature death. Heart attack, kidney failure, stroke, leg amputation, vision loss, and nerve damage are all possible complications. Type 2 diabetes mellitus (T2 DM) is a chronic disease that requires ongoing therapy and patient education to prevent acute complications and lower the risk of long-term complications [13].  
Type 2 diabetes mellitus (T2 DM) problems can be overcome in various ways, including pharmacologically and non-pharmacologically. Non-pharmacological therapy includes lifestyle changes by adjusting diet (medical nutrition therapy), therapy using fruit juice, increasing physical activity, and education on various problems related to diabetes, all of which are continuously carried out. Pharmacological therapy includes oral anti-diabetic administration and insulin injections. Pharmacological therapy should be used in conjunction with non-pharmacological therapy [14].
