Objective To explore the latent classes and the influencing factors of intrinsic capacity among community-dwelling elderly type 2 diabetes mellitus patients with multimorbidity, so as to provide references for developing interventions to enhance their intrinsic capacity.Methods A total of 856 community-dwelling elderly type 2 diabetes mellitus patients with multimorbidity were selected conveniently, then they were investigated by using a general information questionnaire, the intrinsic capacity assessment scale, the Age-friendly Environment Scale, and the Social Support Rating Scale.Latent class analysis was employed to identify the latent classes of intrinsic capacity among the participants, followed by a multivariate logistic regression analysis.Results The intrinsic capacity score of the participants was 4(3,5) points, and 555(64.8%) of them exhibited a decline in intrinsic capacity.The participants′ intrinsic capacity was classified into three latent classes:the relatively stable group (77.8%), the low sensory-low cognitive group (13.6%), and the low vitality-low psychological-low exercise group (8.6%).Regression analysis revealed that, age, sleep duration, comorbidities, level of age-friendly environment, and level of social support were influencing factors of the latent classes of intrinsic capacity among community-dwelling elderly type 2 diabetes mellitus patients with multimorbidity （all P＜0.05）.Conclusion The intrinsic capacity of community-dwelling elderly type 2 diabetes mellitus patients with multimorbidity is heterogeneous, and it is influenced by various factors.Precision intervention strategies should be implemented for different potential categories of this population, so as to enhance their intrinsic capacity and promote healthy aging.
