The WLT vision is about a world where all vulnerable/needy young people can be motivated and empowered to succeed. Nonmedical factors in the environments where people are born, live, learn, work, play, worship, and age affect health, distribution of health among the sub-groups, and the ability to succeed. When there is a healthy life, there is hope for prosperity. These nonmedical factors are known as social determinants of health. WLT explores social determinants of health issues to show how they affect health, quality of life, and the chances of success and prosperity. WLT uses evidence-based recommendations to deal with social determinants of health.
