2921Education and health are two important issues in any era, especially after entering China’s New Era. At the National Health Conference, General Secretary Xi Jinping emphasized that “health should be integrated into all policies”. Adolescent health is the proper meaning of implementing the “Healthy China” strategy, and a sound health education system is conducive to promoting adolescent health. At the same time, the COVID-19 epidemic exposes the weakness of national education in the knowledge of public health and safety.
Given the above context, this paper analyzes the effect of health education in primary or secondary schools on adolescent development. It is found that, health education has a significant promotion effect on adolescent health, but this effect varies with the degree of health education. The promotion effect of health education both in primary and secondary schools, health education only in primary schools and health education only in secondary schools is weakened in turn. The promotion effect relies on the three mechanisms of health behavior and lifestyle, disease prevention and mental health. In further analysis, it is found that health education cannot improve students’ academic performance but academic attitude.
The main contributions are as follows: First, from the research perspective, this paper focuses on how education categories in the horizontal dimension affect health, and analyzes the relationship between health education and health in detail, which is helpful to enrich the existing theoretical research from the “education side”. Second, from the research object, different from the existing literature based on infant groups and middle-aged and elderly groups, this paper selects students receiving junior high school education as the research object, which is helpful to enrich the existing theoretical research from the “health side”. Third, from the action mechanism, this paper confirms the three mechanisms of health education promoting adolescent health, namely, health behavior and lifestyle, disease prevention and mental health. Fourth, from student development, this paper confirms that health promotion can effectively improve students’ academic attitude. Fifth, from practical value, this paper confirms the positive significance of offering health education courses at the stage of basic education, which provides a direct example for the establishment and improvement of education system, and provides an effective material for the deep understanding on “health should be integrated into all policies” from the perspective of education.
