身体形态指数对社区老年人死亡风险的影响研究

Effect of A Body Shape Index on Mortality Risk of Elderly Community Residents

目的探讨身体形态指数(ABSI)对社区老年人死亡风险的影响。方法选取2015年2—12月居住于北京市安华里社区的居民280例。收集研究对象的基线资料,于2022年10月通过电话随访研究对象家庭成员或其他护理人员,收集研究对象的生存/死亡情况。采用多因素Cox比例风险回归分析探讨ABSI对社区老年人死亡风险的影响。结果共剔除33例研究对象,其中30例因测量数据不完整被剔除,3例因失访被剔除。研究期间共死亡70例,将其作为死亡组,其余作为存活组。死亡组年龄大于存活组,男性占比、收缩压、血肌酐、有吸烟史者占比、ABSI高于存活组(P<0.05)。多因素Cox比例风险回归分析结果显示,ABSI是社区老年人死亡的影响因素(P<0.05)。结论ABSI>0.0785时可能增加社区老年人的死亡风险。

Objective To investigate the effect of a body shape index(ABSI)on mortality risk of elderly community residents.Methods A total of 280 residents living in Anhuali Community of Beijing from February to December 2015 were selected.The baseline data of the subjects were collected.Survival/death was collected by telephone follow-up with family members or other caregivers in October 2022.Multivariate Cox proportional hazards regression analysis was used to investigate the effect of ABSI on mortality risk of elderly community residents.Results A total of 33 subjects were excluded,of which 30 were excluded due to lack of measured data and 3 were excluded due to loss to follow-up.A total of 70 subjects died during the study period and were classified as the death group and the rest as the survival group.Age in the death group was older than that in the survival group,male proportion,systolic blood pressure,serum creatinine,proportion of subjects with smoking history and ABSI in the death group were higher than those in the survival group(P<0.05).Multivariate Cox proportional hazards regression analysis showed that ABSI was a influencing factor for death elderly community residents(P<0.05).Conclusion ABSI>0.0785 may increase the risk of death among the elderly in the community.
