It is very important that community health nurse help youth to develop the skills and motivation for effective behavioral changes. Learning brand new behavior is easier than changing existing one. Those behaviors that are learned first, whether they are healthy or unhealthy, are the easiest to maintain. In the context of tobacco, this means that it is important to keep youth tobacco -free because quitting is harder than never starting at all. In the context of diet and exercise, it means that inculcating healthy nutrition and activity habits when they are young will be easier than motivating them to change unhealthy eating habits and sedentary patterns as they get older.
