ABSTRACT

1. 연구의 필요성 최근 평균 수명의 증가로 폐경 여성의 인구가 증가하고 있 다. 이로 인해 골다공증의 유병률 또한 증가되고 있어, 2008 년도에 시행된 국민건강영양조사에서는 50세 이상에서 골다 공증 유병률이 19.3%로 보고되었다. 특히 폐경기 전후의 여 성에서 골다공증의 유병률은 32.6%로 같은 나이의 남성에 비 해 약 6배나 높은 수치를 보인다. 골다공증의 위험 요인으로는 연령의 증가, 운동 부족, 흡 연, 낮은 칼슘 및 비타민 D 섭취 등이 있다. 특히, 폐경기 여 성에서 폐경으로 인한 에스트로겐 결핍은 골소실을 증가시키 고 신장에서 칼슘 분비를 촉진시켜 골다공증 발생이 급격히 증가해 이 시기에는 무엇보다 적극적인 관리가 필요하다. 골 다공증인 경우 골절이 발생하기 쉬우며, 한 번 발생된 골절은 완전한 회복이 어렵고, 장기간의 치료가 필요하여 골다공증 이 발생하기 이전에 이를 예방하는 것이 무엇보다 중요하다 (Jang et al., 2008; Jeong et al., 2000; The Korean Society of Bone Metabolism, 2008).

Purpose: The purpose of this study was to develop the dietary approaches to stop hypertension (DASH) diet education program tailored to Korean adults and to examine the effect of the DASH diet education program on bone mineral density in middle aged women. Methods: The subjects of this study were 26 middle aged women, pre and post menopause, who attend a church located in Kyung-In district. The DASH group I (n=13) was provided with the DASH diet education program only, while the DASH group II (n=13) was provided with DASH diet education program along with calcium supplements (1 g/day). The DASH diet education program included one lecture on DASH diet, one face to face counseling, and five telephone counseling sessions during the 8 weeks period. Results: The knowledge and subjective compliance level of DASH diet increased significantly in both groups, at 4 and 8 weeks after the intervention. The level of objective compliance of DASH diet in both groups increased over the study period, but it was not significant as compared to those of the baseline. Bone mineral density of both groups decreased at 8weeks as compared to the baseline after the intervention. Conclusion: Although 8weeks of DASH diet education program increased the knowledge and compliance of DASH diet, it was not effective to bring the changes in bone mineral density among the middle aged women.
