健康日本21では,歯周疾患は癌,循環器疾患,糖尿病とともに第4の生活習慣病であるとしている。本疾患は発症から歯の喪失に至るまでの慢性疾患である。従って歯周疾患の状況と全身状態,生活習慣,意識的要因との関連を分析し今後の歯科保健対策のあり方を検討した。
　対象は,島根県で平成11年度から開始された8020緊急5ヵ年戦略事業の重点市町村である鹿島町の基本健康診査及び成人歯科健康診断受診者340名と,生活習慣アンケート実施者の94名である。その結果,歯周疾患の重症度と肝機能異常はp<0.05で関連があり,骨運動器疾患の有無と20本以上の残存歯の有無高血圧と歯周病の重症度も有意差が認められた。生活習慣との関連では喫煙本数が多いほど歯周病が重症化しており,食生活との関連でも有意差が認められた。意識的要因では重症の歯周病者でも不自由や苦痛を感じておらず,自覚症状が乏しいことから"歯科保健行動を起こすきっかけ作り"の必要性が示唆された。
Kenko Nippon 21 (Healthy Japan 21) describes periodontal disease as the fourth-ranking lifestyle-related illness after cancer, cardiovaseular disease and diabetes. Periodontal disease is a chronic inflammatory disease finally, Ieading to loss of teeth. We analyzed the relationship between the severity of periodontal disease and systemic conditions, Iife~tyle and self-consciousness as factors for evaluating future dental health measures. A survey was carried out on 340 persons who had undergone a basic medical checkup and a dental checkup for grownups, and 94 respondents to a questionnaire on lifestyle in Kashima town, one of the priority municipalities for five-year emergency strategic project 8020, which began in fiscal 1999 in S prefecture. The results revealed that periodontal disease severity was related to hepatie function disorder (p<0.05), and also to the presence or absence of bone motile organ disease, presence or absence of more than 1 9 remaining teeth and the severity of hypertension.Regarding the correlation of periodontal disease with lifestyle, the greater number of cigarettes were smoked, the more serious periodontal disease was observed. Furthermore, regarding its relationship with eating habits as well, signifrcant difference was observed. Regarding self-consciousness, since even serious periodontal disease patients feel nether inconvenience or pain, nor notice few symptoms, the necessity of acting on the idea of dental health was suggested.
