简要总结
The preschool stage has been identified as an important moment for the study of factors associated with obesity. The worrying national situation of overweight in children from 3 to 5 years old, the increase in consumption of ultra-processed foods nationwide that is associated with the increase of the body mass index at the national level, the reduced national scientific evidence regarding the effectiveness of interventions in promoting healthy habits, as well as the lack of tools for mothers of preschool children in nutrition and physical activity, make interventions necessary in this area. On the other hand, currently, users worldwide are installing fewer applications and, although they spend more time using mobile applications, they are limited to a handful. Therefore, developing a native mobile application that is highly consumed is very difficult and expensive. For this reason, progressive web apps emerge as an attractive alternative for users given its attractive features, cross-platform interface, lower development cost and a growing demand for such applications. Thus, this research seeks to explore a novel way to promote healthy habits in preschoolers and check their effectiveness. In this way, a precedent could be set in the use of technologies in health promotion that could be extended to other age groups.
详细描述
SAMPLE SIZE The sample size was calculated using OpenEpi (www.openepi.com), with the sample size formula to compare two means, considering a confidence interval of 95%, power of 80%, ratio of sample size (group 2 / group 1) equal to 1, a minimum expected mean difference of 5 points and a standard deviation of 9.5 points for both groups. Thus, the required sample size is 114 participants (57 intervened and 57 not intervened).
TECHNIQUES AND PROCEDURES FOR DATA COLLECTION
First stage: Design of the progressive web app
In this phase, the profile of the users will be defined through a focus group. Among the information gathered is socio-demographic data, use of technology, current situation of the feeding and physical activity of the preschool, and expectations of the functions of the computer tool. In addition, a complementary bibliographic search will be carried out on the subject to expand the information necessary for the design of the PWA.
Based on the information collected, the alpha version of the application will be developed. It will undergo a validation process and based on the feedback, the application will be improved until a beta version is developed.
