**8. Conclusion**

This chapter highlighted approaches to determine the prevalence of sedentary and inactive adolescents and examined two premises which are the foundation of research-based behavior change in IA and SB. By examining recently completed SR of behavioral change to reduce IA and SB, this chapter identified methodological, intervention, and alternative clues that challenge and extend the current approaches derived from an SR of 310 studies focused on indicators, clusters, associations, factors, and variables that can ameliorate reductions in sedentary and inactive behavior. The success was that there were clues and cues regardless of outcomes. Altogether, there were 13 clues and 26 cues presented, and while these cannot guarantee success in the aim of reducing SB and IA and increasing PA, they can provide a broader scope as to how researchers are trying to understand how to change behaviors in children and adolescents who are sedentary and inactive. Ultimately, it is unlikely for one panacea to change SB and IA in children and adolescents, and with so many clues and cues, there is a good chance that there will be many solutions. What is critical is to determine what the future panaceas will be that help children and adolescents find their own way of changing their behaviors from being sedentary and toward being more active and healthier. This is a worthy cause that requires researchers, physical educators, children, and adolescents alike to take a cue.
