Construction and Application of Risk Prediction Model of Cognitive Impairment for Elderly Patients with Obstructive Sleep Apnea-Hypopnea Syndrome
Objective To analyze the risk factors for cognitive impairment in elderly patients with Obstructive Sleep Apnea-Hypopnea Syndrome,and to construct and validate the effectiveness of a predictive model.Methods 212 elderly patients with Obstructive Sleep Apnea-Hypopnea Syndrome who visited a Grade-A hospital in Deyang City were conveniently selected as the research subjects from January 2022 to May 2024.The research subjects were divided into a modeling group(148 cases)and a validation group(64 cases)according to a 7:3 ratio.Logistic regression analysis was used to explore the risk factors of cognitive impairment,and a prediction model was established.The diagnostic value of the model was judged by Hosmer-Lemeshow goodness of fit test and ROC curve area.Results The incidence of cognitive impairment was 38.7％among the 212 patients.Age,educational level,body mass index,blood pressure,blood fat,and mean blood oxygen saturation are entered into the prediction model.Conclusion Age,educational level,body mass index,blood pressure,blood fat,and mean blood oxygen saturation can effectively predict the incidence of cognitive impairment in patients.
