A healthy environment is an important thing to encouraging study activity in schools. Both senior and junior high school student’s population have high number in Indonesia. Their ages range between 11 to 18 years old. This might be the transition time from childhood to adulthood. According to Brener et al., the teenager often to have an unhealthy lifestyle, such as smoking, alcohol, less sleep, etc. Generally, boys tend to have unhealthier lifestyle than girls [2][3]. The role of schools in applying a clean and healthy lifestyle in adolescents is really enormous. Adolescents spend a large proportion of their day in school or pursuing school-related activities. Therefore, the healthy lifestyle of adolescents is strongly influenced by the surrounding environment including school environment. Basically, the school also tries to organize programs that can improve the healthy lifestyle of the students. Schools seek to affect student’s health in a number of ways including: teaching (health classes); exercise via physical education classes and extra-curricular sports; nutrition through school lunch content, off-campus eating policies, and vending machine content; and, in some cases, the provision of direct medical services. Many children consume at least half of their daily calories at school. As families work to ensure our kids eat right and have an active play at home, we also need to ensure our children have access to healthy food and opportunities to be physically active in their schools. Because over 95% of young people are enrolled in schools, the school setting can offer multiple opportunities for students to engage in physical activity such as physical education classes, recess periods for unstructured play in elementary schools, afterschool programs, intramural sports programs and physical activity clubs. These opportunities are particularly important because they are accessible to all students, including those who are not athletically gifted and those with special health care needs. This information can be published in our peer-reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
