Association between triglyceride glucose index and depression in hypertensive population

Previous studies have shown a significant association between the triglyceride glucose index (TyG) and suicidal ideation in Korean women. However, this association has not yet been examined among American adults. This study aims to investigate the association between TyG and suicidal ideation using data from the National Health and Nutrition Examination Survey. The National Health and Nutrition Examination Survey database from 2005 to 2018 was used, including samples ≥20 years old. Suicidal ideation was assessed through questionnaires, and the TyG was derived from fasting triglyceride and glucose measurements. Weighted logistic regression models were used to analyze the relationship between the TyG and suicidal ideation. Generalized additive model curves explored the nonlinear relationship, while stratified and sensitivity analyses assessed potential interactions and the robustness of the findings. A significance level of P < .05 was considered statistically significant. A total of 15,694 participants were enrolled, of whom 3.67% participants showed suicidal ideation. The mean TyG index for participants with or without suicidal ideation was 8.82 ± 0.76, 8.65 ± 0.68, respectively (P < .001). Multivariable logistic regression showed that a higher level of TyG were associated with a higher likelihood of suicidal ideation (OR = 1.20; 95% CI, 1.05–1.38) after full adjustment. Subgroup analysis and interaction tests showed no significant correlation between gender, age, race, marital status, education, body mass index, poverty income ratio, smoking status, drinking status, diabetes, hypertension, stroke, and cancer (P > .05 for all interactions). Our findings confirm a significant and positive association between the TyG and suicidal ideation among American adults. Further large-scale prospective studies are needed to analyze the role of TyG in suicidal ideation.

Aims Herein, we examined the correlation between platelet/high-density lipoprotein cholesterol ratio (PHR) and symptoms of depression among United States adults. Methods Data acquired from the 2007–2018 National Health and Nutrition Examination Survey, involving individuals ≥ 20 years of age, with available PHR and depression diagnosis information. We employed weighted uni- and multivariable logistic regression analyses to assess the distinct correlation between PHR and depressive symptoms. Additionally, we conducted subgroup, interaction, and restricted cubic spline analyses. Results In all, 28,098 subjects were recruited for analysis, with 8.04% depression status and 19.31 ± 0.11 mean PHR value. Depressive symptoms increased with higher quartiles of PHR. Following fully confounder adjustments in model 2, participants with the largest PHR quartiles exhibited a 53% (OR: 1.53, 95%CI: 1.00–2.33, P = 0.05) raised depressive symptoms, relative to participants with least PHR quartiles. Based on the two-piece-wise regression, the breakpoint was PHR = 23.76, and a positive association was more evident when PHR < 23.76 (OR = 1.06, 95%CI: 1.02–1.10, P = 0.01). When PHR ≥ 23.76, the correlation disappeared (P = 0.85). Using subgroup and interaction analyses, we revealed a positive relationship between PHR and depressive symptoms almost consistent among various population settings. Conclusions A convenient biomarker, the PHR was independently associated with an increased risk of depressive symptoms and may be a promising new bioindicator for the prediction of depression diagnosis.
