Outline of Final Research Achievements |
Between April 2013 and December 2016, 37823 subjects had proteinuria at their annual health checkups in the national health insurance system and the medical care system for the elderly aged 75 and over in Osaka prefecture. Only 11187 (30.0%) patients with proteinuria had follow-up tests of proteinuria within 12 months after their checkups. In patients with “underweight” (BMI<18.5 kg/m2), “normal weight” (18.5-24.9), “overweight” (25.0-29.9), and “obesity” (≧30.0), the follow-up tests were observed in 908 (35.5%), 6388 (30.3%), 3189 (27.6%), and 702 (27.0%) patients, respectively. After adjusting for clinical baseline characteristics using a discrete time hazard model with complementary log-log link, the patients with “overweight” and “obesity” had significantly lower probability of the follow-up tests of proteinuria. The present study revealed that patients with proteinuria and overweight/obesity should be actively encouraged to access to the healthcare system.

Academic Significance and Societal Importance of the Research Achievements |
平成20年4月から特定健診が40歳以上の国民に義務付けされているが、健診受診後の医療機関の受診について調べた報告は、ほとんどみられない。本研究は、慢性腎臓病の早期診断項目であるタンパク尿の健診での発見とその後の医療機関の受診との関係を調べた点で目新しい。また、早期医療アクセスを阻害するリスク因子としてのBMIの重要性を明らかにすることによって、肥満患者を健診受診後の重点的な受診勧奨すべき対象として同定することができた。肥満は慢性腎臓病のリスク因子であるが、肥満患者の慢性腎臓病のリスクを下げる方法として、肥満患者への受診勧奨が重要であることが示された。
