The relationship of lymphocyte to high‐density lipoprotein ratio (LHR) with depression remains uncertain. We aimed to evaluate the association between LHR and depression in US adults.
In this cross‐sectional study, a total of 4216 participants were enrolled from the National Health and Nutrition Examination Survey (2015–2018). Depressive symptoms were measured with the Patient Health Questionnaire‐9 (PHQ‐9). Participants were classified as having depression if PHQ‐9 scores were ≥10. Multiple logistic regression models were used to explore the relationship between the LHR and depression.
Overall, the LHR was significantly associated with depression (per standard deviation increment; adjusted odds ratio (OR), 1.31; 95% confidence interval (CI) [1.14, 1.50]) after adjusted potential variables. Interactions between LHR with metabolic syndrome (MetS) and body mass index (BMI) on the risk of depression were found in stratified analysis ( p for interaction < .05).
