The BASIC DEVELOPMENT NEEDS (BDN) are effective on human health. Since there was no research about the effects of BDN on the HEALTH INDICATOR s, this study was carried out to compare HEALTH INDICATOR s in pilot villages of BDN in Charmahal and Bakhtiari province. A 4 years period (2000-2004) case-control study was carried out in 8 villages (4 cases and 4 controls) of Saman city. First, a questionnaire about access to healthy bath, collection system for garbage, collection system of waste water, access to sanitary toilet, income and social projects was filled for 1582 families in each group of case and control. Then BDN project was carried out in the case villages for a period of four years. Then the above questionnaire was filled again for all the villages. The results were statically analyzed using chi-square test. All the HEALTH INDICATOR s were improved in the case group (p< 0.001). BDN improves the HEALTH INDICATOR s, family income and participation in the social projects.
