Development and Usability of a Life-Logging Behavior Monitoring Application for Obese Patients

Abstract

BackgroundObesity is a global epidemic. Behavior change monitoring using a smartphone application (app) can support weight management in obese patients. These apps must undergo usability testing, which is an important step in mobile healthcare app development. The current study aimed to develop a mobile app for behavioral monitoring and to test its usability including technical effectiveness, user efficiency, and user satisfaction for obese adults.MethodsDevelopment of the Dr. Youth app components included information on behavioral monitoring indicators and their obesity subtypes. The usability of the app was tested with 50 obese adults in a university hospital. Participants were asked to complete eight tasks for evaluating the technical effectiveness of the app. The time to complete each task was measured to test user efficiency. To explore user satisfaction, each participant completed the System Usability Scale (SUS). Descriptive statistics were used to examine the mean user efficiency and SUS scores.ResultsFifty adults (14 men and 36 women, aged 20–59 years) who are obese (body mass index ≥25 kg/m2) were recruited. The mean age of participants was 42.6 years (standard deviation [SD], 10.8 years); their mean body mass index was 29.6 kg/m2 (SD, 5.7 kg/m2). The tasks were completed with a 99% success rate. The overall mean SUS score was 76.65 (SD, 15.43).ConclusionThe Dr. Youth app shows acceptable technical effectiveness, user efficiency, and user satisfaction. Future study is warranted to establish the app’s clinical efficacy.

Early Detection and Education of Potential Obesity for Prospective Brides Using an Android-Based Botting Macca Application

“…This study described the characteristics of the respondents in two groups (Table 5) There were 29.4% of women aged 19 -55 years observing at risk for obesity and most of them had a sedentary lifestyle or light activity. Examples of a sedentary lifestyle are students (not working), housewive, entrepreneurs/traders, workers in private sector, etc) (JY Lee et al 2019). The use of MUAC in this study is in line with the research conducted by Shane HR and Pasiak (2016) stating that there is a relationship between upper arm circumference and obesity.…”

“…The use of the application makes it easier for public and medical personnel to control and reduce the number of overweight and obesity and other health problems (Amelia et al 2020). Several policies in some countries have established countermeasures through surveys from the results of application assessments for some health problems (JY Lee et al 2019).…”

NemoSuite: Web-based Network Motif Analytic Suite

“…Nemo and FANMOD programs have good usability too. Usability measures "the capacity of a system to provide an environment for the users to perform the tasks safely, effectively, and efficiently [46]." With Nemo and FANMOD, network motifs are easily detected given an input graph, the size of motif, and the number of random graphs to generate.…”

Implementing Visual Analytics Pipelines with Simulation Data

“…Usability can be defined as the capacity of a software system to provide a condition for its users to perform tasks in a safe, effective, and efficient manner while enjoying user experience [2]. Usability requires techniques for assessing it, such as needs analysis [3] and the study of the values underlying perceived utility or beauty of the object.…”
