The purpose of this concluding is to review some of the major issues that have been highlighted by the various authors in book under this title. A major underlying theme, is that there is not a simple, one way correlation between "greater development" and "better health", but we can find "different health" and not simply "better health".This is only one of many challenges there is between health and development. Authors have a list of challenges between health and development.They hope, readers, who can point to inequalities, show examples of good and bad practice and perhaps, generally help to raise awareness of what needs to be done and what might be achieved.In terms of social circumstances such as living alone, being single parent, or living in a marriage or marriage-like relationship, the unemployed subjects of general population differed from the employed. Regular smoking was mush more common among the unemployed. Alcohol-related problems, mental health problems, suicidal thoughts, and diminished zest for life were reported more by unemployed subject and subjects afraid of unemployment. Uncertainty about future, use of hypnotics or sedatives, and perceived mental ill-health were more common among unemployed subjects, subjects afraid of unemployment, and their spouses. Use of control group and valid scales are the benefits of the research in contrast to other similar studies.
