Abstract:
Objective To introduce the Multi-kink quantile regression model and its application in the association analysis of sleep duration and depression.Methods We fit the Multi-kink Quantile Regression Model to estimate regression coefficients and the kink points locations,and test the existence of the kink effect through the MultiKink package in the R software.Results We identify a significant nonlinear relationship between depression and sleep duration,and the score of depression was the lowest in the sleep duration of 7～8 hours.Sleep duration has a greater impact on the higher quantile for depression.Conclusion Multi-kink quantile regression model has good fitting effect and wide applicability,and the analysis results can provide more targeted advice of clinical and public health intervention for high-risk population.
