بررسی عوامل مرتبط در استفاده از کلر 1% در خانوارهای تحت پوشش خانه های بهداشت استان سیستان و بلوچستان، 1380

According to the reports of world health organization (WHO), 80 percent of human diseases are due to contaminated water either for drinking or sanitation. International water sanitation program says that 50 percent of people across the world have no access to healthy water and 75 percent of the third world population do not have water for sanitation. The present semi experimental study aims at determining factors relevant to the chlorination in the families under the coverage of health houses of Sistan and Baluchestan province. Research sample was composed of 2100 households which were under the coverage of health houses of the province. They were investigated in two groups (case and control) on the basis of stratified and random sampling. The findings indicated that 37.5. Percent of households who used 1% chlorine for chlorination, had a comprehensive knowledge about it and of which 23.5 percent belonged to the control group. The results of logestic regression indicated that those who had good or moderate knowledge, used 1% chlorine for chlorination more than the group with poor knowledge. Finding also showed that 98.8 percent in case group and 93.7 percent in the other one had a positive approach to chlorination. Furthermore, a significant correlation was established between approaches and performances of both groups (P<0.05). Meaningful relationships existed between the level of knowledge and approaches, household and ethnicity, the performances and the size of the households (P< 0.05). Reasons for not doing chlorination were awful taste and smell (37.65%), no access to chlorine (26.64%) and time limitation to do so (18.23%), meanwhile, those who were doing chlorination mentioned that prevention of diseases (68.88%), considering sanitary principles (16.06%) and a combination of these two (12.06%) are our reasons for doing this task. To conclude, regarding the results of this study training programs should be considered to enhance awareness about the importance of chlorination and the usage method, in order to prevent undesirable physical damages due to contaminated water.
