Encouraging researchers to use a transdisciplinary, collaborative and systems approach to address disparities in chronic disease prevention, the program will emphasize prevention, early detection, and early treatment. Studies have shown that early treatment improves health outcomes in many conditions, implying that early detection is important to combatting disease progression. However, people from health disparity populations, generally have lower detection rates, leading to later-stage diagnosis and treatment, which can negatively impact disease outcomes.
Strong, secure relationships help stabilize children's behavior and provide the core guidance needed to build lifelong social skills. Children who grow up with such relationships learn healthy, appropriate emotional responses to everyday situations. But children raised in poor households often fail to learn these responses, to the detriment of their school performance. For example, students with emotional dysregulation may get so easily frustrated that they give up on a task when success was just moments away. And social dysfunction may inhibit students' ability to work well in cooperative groups, quite possibly leading to their exclusion by group members who believe they aren't "doing their part” or "pulling their share of the load.” This exclusion and the accompanying decrease in collaboration and exchange of information exacerbate at-risk students' already shaky academic performance and behavior.
The absolute poverty measure trends noted above are supported by human development indicators, which have also been improving. Life expectancy has greatly increased in the developing world since World War II and is starting to close the gap to the developed world. [ citation needed ] Child mortality has decreased in every developing region of the world.  The proportion of the world's population living in countries where per-capita food supplies are less than 2,200 calories (9,200 kilojoules ) per day decreased from 56% in the mid-1960s to below 10% by the 1990s. Similar trends can be observed for literacy, access to clean water and electricity and basic consumer items.
