ABSTRACT
Objective: To investigate the correlation and sex difference between obstructive sleep apnea hypopnea syndrome (OSAHS) and liver injury. Methods: A total of 974 OSAHS patients (444 cases of mild to moderate, 530 cases of severe) and 111 cases of simple snoring in the First Affiliated Hospital of Fujian Medical University and Zhangzhou Municipal Hospital from November 2015 to September 2019 were included in the study. The basic information of the patients was obtained through face-to-face survey with self-made questionnaire, physical examination, sleep monitoring and blood biochemical and liver function index detection were carried out among the included subjects. Multiple logistic regression model was used to analyze the correlation between OSAHS and liver injury and the gender differences. Results: The subjects were (50±14) years old, including 841 males (77.5%). Statistically significant differences in total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), fasting blood glucose, alamine aminotransferase (ALT), aspartate aminotransferase (AST), ALT/AST, gamma glutamyltransferase (GGT), the rate of elevated ALT, AST and liver injury were observed among the three groups (all P values<0.05). There was no significant difference in total bilirubin and ALP among all groups (all P values>0.05). Multivariate logistic regression showed that after adjusting for confounding factors, severe OSAHS was positively correlated with liver injury [OR (95%CI): 2.25 (1.22-4.14)]. Subgroup analysis by gender showed that severe OSAHS was positively correlated with liver injury in males [OR (95%CI): 2.20 (1.04-4.65)], but not in females, mild to moderate OSAHS [OR (95%CI): 1.56 (0.52-4.71)] or severe OSAHS [OR (95%CI): 2.07(0.64-6.75)], after adjusting for confounding factors. Conclusion: Severe OSAHS is positively correlated with liver injury in males, while female OSAHS is not associated with liver injury.
