Human beings are at the centre of concerns of sustainable development while sustainable development is the key to improved health .Sustainable development is defined as the need to achieve greater social equity or avoidance of the imposition of added costs or risks on succeeding generation (EDAW97).Many slum areas evolved from rapid unplanned urbanization leading to unhealthy environment which had a major role in the development of poor health in those slum areas .In most of slum areas ;densities are high and associated with rang of problems .Management and improvements of infrastructure specially roads ,sanitation ,air pollution and lack of public green spaces will lead to healthy communities. The problem is how to improve the quality of life of those communities through a healthy residential environment. The paper aims to study the process of Improving health in slums by increasing the public awareness of using good ventilation, Painting and finishing material not harming the health. Health services has an important role to play in sustainable development reducing the disease burden This role was being undermined by the insecurity of health services in poor slums “Poverty increases vulnerability to poor health and poor health increases vulnerability to poverty.”(WHO2002).Some of the causes of the increase of the disease burden is the deterioration in the state of the environment which exposes people to pollutants and toxics materials. This will result in a range of effects on health which will ultimately require; Governance, NGO, people participation and other steak holders should take various actions to achieve the aim of the study. The data that was presented; indicated that 78% of children attending schools in poor slums in the city have blood lead levels equaling , or higher than the international action level of 10g/dl. The study will be in Al-Gamalia in Al Azhar district, using a cross-sectional study to show how rapid unplanned urbanization could lead to people living in settings in which shelter was insecure, air quality was poor, access to water and sanitation was limited. In addition, residents of this region constantly had to deal with high levels of noise, a lack of adequate ventilation, limited privacy and the threat of violence. In these highly marginalized communities, health status, especially that of known high-risk groups such as young children and old people was particularly poor, leading to a situation of unsustainable development.
