FRIDAY, April 14, 2023 -- Machine learning models can effectively predict risk for a sleep disorder using demographic, laboratory, physical exam, and lifestyle covariates, according to a study published online April 12 in PLOS ONE.
Alexander A. Huang, from the Northwestern University Feinberg School of Medicine in Chicago, and Samuel Y. Huang, from Virginia Commonwealth University in Richmond, used data from 7,929 participants in the National Health and Nutrition Examination Survey to identify risk factors associated with sleep disorders through machine learning.
The researchers found that the machine learning model identified 64 of 684 features that were significant in a univariate analysis. Following fit into the XGBoost model, performance had an area under the receiver operating curve of 0.87, sensitivity of 0.77, and specificity of 0.77. The features with the highest measure of percentage contribution to the overall model prediction included the Patient Health Questionnaire depression survey (31.1 percent), age (7.54 percent), physician recommendation of exercise (3.86 percent), weight (2.99 percent), and waist circumference (2.70 percent).
