Health awareness plays an important role in our life. It’s important to live an appropriate lifestyle because an adequate way of life helps to conserve the optimal health status and to prevent chronic diseases (Conner, 2005). The role of the family and parents is still significant. Children turn toward their peers but the family stands in the background as a supporting basis (Kovács & Pikó, 2009). However this function cannot be fulfilled with the crisis and disintegration of family structure which can mean a serious stressor, so it can increase the appearance and in serious cases the long-lasting subsistence of harmful health behavior (Bramlett & Blumber, 2007). The aim of the study is to measure the appearance of smoking, getting drunk, and substance use depending on the sport and family structure in three counties on the basis of FASCES 2015. According to the results only pursuing sport does not influence the testing rate but it can be seen as a protective factor. Family structure considered on its own is not a significant influencing factor but the mediating role of social factors are well perceptible in case of smoking, getting drunk, and using weed.
