To explore the latent profiles of loneliness in community-dwelling older adults and to explore the relationship between categories and cognitive functioning to inform targeted interventions.
A survey was conducted on 658 elderly individuals from 9 communities in Henan Province using the Simplified Loneliness Scale and the Montreal Cognitive Assessment Scale. Mplus8.3 was used for latent profile analysis, and SPSS26.0 software was used to compare the cognitive function differences of elderly people with different types of loneliness.
Prevalence rate of mild cognitive impairment in community-dwelling older adults 31.00% (204/658). The latent profiles of loneliness symptoms in community-dwelling older adults can be categorized into three latent profiles: low loneliness group (54.4%), social loneliness group (24.3%), and emotional loneliness group (21.3%). Community-dwelling older adults in the emotional loneliness group had a higher risk of cognitive impairment compared to the low loneliness group (OR = 1.693, < 0.05).
Three categories of loneliness exist in community-dwelling older adults, with differences in cognitive functioning among community-dwelling older adults with different latent profiles. Community healthcare workers should pay attention to the loneliness of older adults during cognitive function screening, and especially provide psychological counseling to emotionally isolated community-dwelling older adults in order to reduce the risk of cognitive impairment.
探讨社区老年人孤独感的潜在类型，并探究不同类型与认知功能之间的关系，为针对性干预提供依据。
采用简化孤独量表和蒙特利尔认知评估量表，对河南省9个社区的658名老年人进行调查。使用Mplus8.3进行潜在类别分析，并用SPSS26.0软件比较不同孤独类型老年人的认知功能差异。
社区老年人轻度认知障碍患病率为31.00%（204/658）。社区老年人孤独症状的潜在类型可分为三类：低孤独组（54.4%）、社交孤独组（24.3%）和情感孤独组（21.3%）。与低孤独组相比，情感孤独组的社区老年人发生认知障碍的风险更高（OR = 1.693，< 0.05）。
社区老年人存在三类孤独感，不同潜在类型的社区老年人在认知功能上存在差异。社区医护人员在认知功能筛查时应关注老年人的孤独感，尤其要为情感孤独的社区老年人提供心理咨询，以降低认知障碍风险。
