摘要：

The ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol, abbreviated as NHHR, represents a brand-new lipid biomarker for assessing cardiovascular disease risk. Research has suggested a link between lipid metabolism and obstructive sleep apnea (OSA). To delve deeper, this study was carried out using data derived from the NHANES to ascertain whether NHHR and OSA are associated. In this research, a cross-sectional analysis was executed based on data derived from NHANES across the years 2005 to 2008 and 2015 to 2020. After adjusting for confounders such as demographic characteristics, lifestyle, and health status, the link between NHHR and the likelihood of developing OSA was examined via weighted binary logistic regression as well as restricted cubic spline (RCS) models. In addition, subgroup analysis was completed to check if the obtained results were reliable. The study included 16,265 adult participants. Following comprehensive adjustment for confounders, results obtained suggested that, for each additional unit increment of NHHR, there is a 9% increased chance of developing OSA. Compared to the lowest quartile, the highest quartile of NHHR notably increased the risk of developing OSA in the overall population (OR: 1.65; 95% CI: 1.38-1.98; P < .001). The RCS curve indicated a linear positive correlation between NHHR and OSA, which remained significant in subsequent subgroup analyses (all P for interaction > .05). This suggested that the correlation between NHHR and OSA was stable across populations with different characteristics. Confounders such as demographics, lifestyle, and health status did not significantly affect this positive correlation. Findings from this study uncovered a strong connection between NHHR and an increased possibility of developing OSA in American adults. Further exploration of NHHR could offer insights into OSA prevention and treatment. However, owing to the constraints inherent in cross-sectional studies, more studies are required to establish a concrete link between NHHR and OSA.
