본 연구의 목적은 대사증후군이 당뇨병으로 확대되는 것을 방지하는데 이용할 수 있는 구체적인 분류 규칙을 도출하는 것이다. 좀 더 구체적으로 말하면, 대사증후군을 앓고 있는 사람들을 당뇨병이 없는 사람 (class 0)과 당뇨병이 있는 사람(class 1)으로 구별해 내는 분류하는 규칙을 찾는 것이다. 본 연구는 국민건강영양조사 데이터를 수집하여 데이터 전처리 과정들을 거친 후 의사결정나무를 구축하였다. 생성된 의사결정나무로부터 유용한 5개의 분류 규칙을 도출하였는데, 이들의 평균 분류 정확도는 75.8%이었다. 또한, 생성된 의사결정나무로부터 고혈압 여부와 허리둘레가 class 0 그룹과 class 1 그룹으로 분류하는데 있어서 중요한 요인임을 알 수 있었다. 이번 연구 결과는 의사들이 향후 대사증후군 환자가 당뇨환자가 되지 않도록 치료하는데 좋은 지침이 될 것으로 기대된다.
