In the adjusted model, when all characteristics of the child and mother, household wealth status, availability of safe drinking water, availability of a hygienic toilet facility, type of fuel used for cooking, urban/rural residence and geographic divisions were controlled for, the relationship of multiple birth and infant mortality remains significant.
This modification notably increases productivity while maintaining the advantages of the still such as ease of handling, low-tech requirements, material availability, safe water quality, sustainability and space conservation.
The availability of safe water and sanitation facilities, the degree of crowding, the underlying health status of the population, and the availability of healthcare services all interact within the context of the local disease ecology to influence the risk for communicable diseases and death in the affected population.
Indeed, understanding risk factors is essential in designing appropriate interventions for the 'F' and 'E' components of the SAFE strategy (e.g. water availability for Facial cleanliness and Environmental improvements) [ 16].
There is a major increase in the availability of safe water sources (boreholes, shallow wells and rainwater harvesting), from 42% to 93% of the community.
Increasing the availability of safe water is also fundamental in cities, mostly for people living in slums.
For a large number of population in the world, specifically in the developing countries, the availability of safe water for daily sustenance is none.
One of the key challenges faced by disabled people, especially in the developing world, is lack of access to basic sanitation and the availability of safe water.
The Standard of Living Index was computed by summing the standard scores of the availability of safe water and the average number of rooms per person, as suggested by the United Nations Millennium Goals Indicators [31].
