Outline of Final Research Achievements

It is widely known that patients with schizophrenia have a shorter life expectancy than the general population. We focused on the physical problem of underweight as one of the factors, and hypothesized that antipsychotic polypharmacy and the number of remaining teeth in patients withschizophrenia may have an effect on low body mass index. We investigated the effects of the number of remaining teeth and the number of antipsychotic drugs prescribed on BMI in inpatients with schizophrenia.

Academic Significance and Societal Importance of the Research Achievements

日本の入院統合失調症患者において低体重・低栄養の割合が高いという事実を確認したのは、我々の報告が初めてである(Sugai et al. 2015)。同集団を対象として身体リスク軽減を目指した治療法を模索することは極めて重要である。
本研究により、統合失調症患者における低体重・低栄養ひいては死亡リスクの増大につながる要因を確認できれば、患者やその家族、医療従事者の問題意識を高め、その予防策の検討・実施につながると考えられ学術的、社会的な意義も高い。
