| アブストラクト | BACKGROUND: Although body mass index (BMI) is a simple marker of in-hospital cardiac arrest (IHCA) in patients with cerebro- and cardiovascular disease, the association between BMI on admission and the incidence of IHCA is still controversial. In this study, Japanese patients with cerebro- and cardiovascular disease were investigated for the association between BMI on admission and the incidence of IHCA. METHODS AND RESULTS: This was a retrospective study from the Japanese Registry Of All cardiac and vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC), a large-scale nationwide claims-based database, using data from between 2012 and 2021. From among all 10,923,676 cases, 7,571,826 patients who were hospitalized for cerebro- or cardiovascular disease were investigated. BMI was classified as underweight (<18.5 kg/m(2)), normal and under ideal (18.5-22 kg/m(2)), normal and over ideal (22-25 kg/m(2)), or obese (>/=25.0 kg/m(2)). The average age, ratio of males, and average BMI were 71.6+/-12.8 years, 63.4%, and 23.3+/-3.7 kg/m(2), respectively. IHCA occurred in 270,380 cases (3.57%). In a Cox regression analysis according to BMI group, the underweight group showed significantly higher hazard risk for the incidence of IHCA after adjusting cofounding factors, both in all patients and a subgroup analysis according to the patient's age generation. CONCLUSIONS: Underweight, rather than obesity, might be a risk factor for IHCA in an aging society. |
