This study is a single-group repetitive experiment conducted to develop the water intake intervention program for the elderly living in the community to confirm its effectiveness. The intervention program was developed by applying Bandura's theory of self-efficacy and consisted of a total of 4 weeks of intervention and 2 weeks of voluntary intake. The pilot test for evaluating the developed program was conducted from May 20 to July 15, 2019. As a result of the study, the degree of moisture intake of the subjects was statistically significant in the water related knowledge as a result of preliminary and post-verification tests on the living together family type, water related knowledge and self-efficacy. As a result of repeated analysis of changes in water intake and blood components, hemoglobin, MCH, and MCHC among water intake and blood components increased, and MPV decreased, which was statistically significant. Based on the results of this study, it is required to study the effect of water intake on cardiovascular risk after revising and supplementing the water intake intervention program.
