The main question in this paper is whether perceptions of health are similar across age groups. If yes, what are these differences? To answer this question, Grounded Theory and Semi-Structured Interviewing Technique with 34Young Adults in Semnan City were used. This study was conducted in two neighborhoods with different levels of economic well-being. This study was conducted in two neighborhoods with different levels of economic well-being and with the emergence of categories, it became theoretical sampling, and with the non-emergence of a new concept in the last four interviews, it became final. Purposeful sampling was used to select the sample of this research. The findings show that there are four main categories of health, health, perception of life, and behavior therapy in understanding health behavior. According to the identified categories and subcategories, four main paradigms were identified. These paradigms are 1. The paradigm pattern of traditional behavior, 2. The beautiful and fit body pattern, 3. The body pattern as a tool, 4. The pattern of returning to nature. Young people are mainly seen in the age group of a beautiful and fit body. The message conditions in this model are the emergence of secondary disease and the dramatic consumption of health goods. Adults are mainly placed in the body pattern by tools.
