Objective:To analyze the frailty status and its influencing factors among middle-aged and elderly individuals of Zhiguo ethnic groups in Yunnan Province.Methods:A cross-sectional study was conducted using a multi-stage random cluster sampling method in the settlements of the Zhiguo ethnic groups in Yunnan Province from July to December in 2022. The study enrolled a total of 1 036 middle-aged and elderly individuals aged 45 years and above. Data on general characteristics (including chronic disease prevalence, sleep quality, smoking and alcohol consumption) and frailty status were collected in the subjects. A total of 1 050 questionnaires were distributed, 1 040 questionnaires returned with 1 036 valid responses (98.7%). Logistic regression analysis was performed to identify factors influencing frailty status among different Zhiguo ethnic groups.Results:Among the 1 036 middle-aged and elderly individuals of Zhiguo ethnic groups in Yunnan Province, there were 482 males and 554 females, with a frailty rate of 26.25% (272/1 036), the Bulang ethnic group had the highest frailty rate (35.56%) and the Jinuo ethnic group showed the lowest (18.49%). Being aged≥60 years ( OR=1.647, 95% CI: 1.177-2.303), having≥2 chronic diseases ( OR=2.183, 95% CI: 1.470-3.245), and suffering from sleep disorders ( OR=2.468, 95% CI: 1.786-3.411) were positively associated with frailty occurrence, whereas having high social support ( OR=0.614, 95% CI: 0.434-0.867) was inversely associated with the risk of frailty (all P<0.05). Ethnic subgroup analyses revealed that suffering from sleep disorders were a common influencing factor for frailty across all Zhiguo ethnic groups (all P<0.05). In the Jinuo ethnic group, having≥2 chronic diseases showed a positive association with frailty ( OR=3.387, 95% CI: 1.054-10.879) ( P<0.05). In the Bulang subgroup, having≥2 chronic diseases ( OR=3.951, 95% CI: 1.201-12.995) and aged ≥60 years ( OR=3.415, 95% CI: 1.347-8.657) were both positively associated with frailty, while having high social support ( OR=0.185, 95% CI: 0.065-0.527) was inversely associated with the risk of frailty (all P<0.05). Conclusion:The frailty rate in middle-aged and elderly individuals among Zhiguo ethnic groups in Yunnan Province is notably high, and sleep quality, social support, and chronic conditions are its main influencing factors.

Objective To evaluate the application value of focused assessment with sonography for trauma (FAST) in treatment of emergency thoracic and abdominal closed injury.Methods FAST examination was performed in 85 patients with thoracic and abdominal closed injury,to determine whether the thoracic and abdominal cavity,pericardial free effusion and abdominal parenchyma organ injury,and the results were compared with conventional ultrasonography,CT scan and operation results.Results FAST was (2.85 ± 1.15) min,conventional ultrasonography was (15.48 ±5.17) min,there was statistically significant difference (t =21.99,P ＜ 0.05).In 85 patients,10 cases were FAST positive,5 cases of abdominal cavity in that amount or a large number of free effusion,underwent emergency operation,postoperative intra abdominal parenchymal organs were confirmed as rupture and hemoperitoneum; 2 cases of renal rupture with perirenal hematoma,confirmed by the whole abdominal CT examination; 2 cases of thoracic free pneumatosis,effusion,confirmed by thoracic CT examination or closed thoracic drainage; 1 case of prompt hemopericardium,confirmed by the pericardium puncture.Conventional ultrasonography was positive in 11 patients,no statistically significant difference between them (P ＞ 0.05).The sensitivity,specificity,accuracy rate of FAST screening thoracic and abdominal closed injury was 10/12,100.0％ (73/73),97.6％ (83/85).Conclusions FAST has high sensitivity and specificity for thoracic and abdominal cavity,pericardial free effusion,check with short time,low environmental requirements,without moving the trauma patients,and may be out of sync with the fluid resuscitation and other emergency measures.For large quantities of trauma patients and patients with severe multiple trauma,FAST can quickly,accurately determine the existence of thoracic and abdominal closed injury,and provide guidance for clinical treatment,which has good application value.
