Objective To explore the status and influencing factors of frailty among the oldest old in community, and to provide refe-rence for intervention research in the future. Methods A total of 272 oldest old individuals aged ≥80 years in Chongqing community were selected by convenience sampling. They were investigated by a general questionnaire, the health condition questionnaire, the Activities of Daily Living Scale （ADL）,the Mini-Nutritional Assessment-Short Form (MNA-SF), the Mini-Mental State Scale （MMSE） and 5-Item Geriatric Depression Scale （GDS-5）. The status of frailty was evaluated by the frailty phenotype. Results Among 272 oldest-old individuals, 80 （29.4%） were frail, 112 （41.2%） were pre-frail and 80 （29.4%） were robust. Grip weakness and slow walking speed were the two major frailty problems. Ordinal logistic regression analysis showed that frequency of physical exercise, polypharmacy, usage of assisted walking devices, activities of daily living, nutritional status and depression were influencing factors of frailty. Conclusion The incidence of frailty and pre-frailty are high among the oldest-old in community. Health care workers should pay attention to early screening of frailty and pre-frailty among the oldest-old in community, and conduct health interventions from multiple dimensions.
