Guo J, Wang L, Zhao X, Wang D, Zhang X. Sex difference in association between suicide attempts and lipid profile in first-episode and drug naive patients with major depressive disorder. J Psychiatr Res 2024; 172:24-33.

Abstract
BACKGROUND The relationship between suicide attempts and lipid profiles in patients with major depressive disorder (MDD) remains uncertain. The purpose of this study was to investigate sex differences in the relationship between suicide attempts and plasma lipid profiles in a large sample of first-episode and drug naive (FEDN) MDD patients. METHODS We recruited 1718 FEDN MDD patients and gathered demographic, clinical, and blood lipid data. The Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale and the Positive and Negative Syndrome Scale were used to assess the symptoms of patients. RESULTS There was no significant difference in the prevalence of suicide attempts between male and female MDD patients. The suicide attempt group had higher levels of depression, anxiety, psychotic symptoms, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C), but lower levels of high-density lipoprotein cholesterol (HDL-C) levels than the non-suicide attempt group. Binary logistic regression showed that TC levels were significantly correlated with suicidal attempts in both male and female patients. Correlation analysis revealed that the levels of TC, HDL-C and LDL-C were significantly associated with the number of suicide attempts in both male and female patients. Further multiple linear regression revealed that TC levels were significantly associated with the number of suicide attempts in male patients only. CONCLUSIONS Lipid biomarkers, particularly high TC levels, are associated with suicide attempts in both male and female MDD patients. However, there is gender difference in association between lipid biomarkers, especially TC levels, and the number of suicide attempts in MDD patients.

The association between non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) and suicidal ideation in adults: a population-based study in the United States. Lipids Health Dis 2024; 23:17. [PMID: 38218917 PMCID: PMC10788025 DOI: 10.1186/s12944-024-02012-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 01/09/2024] [Indexed: 01/15/2024] Open
Abstract
BACKGROUND The ratio of non-high-density lipoprotein cholesterol (non-HDL-C) to high-density lipoprotein cholesterol (HDL-C) (NHHR) serves as a reliable lipid indicator associated with atherogenic characteristics. Studies have indicated a potential connection between suicidality and lipid metabolism. This research aims to investigate any possible association between the NHHR and the emergence of suicidal ideation within the confines of the study. METHODS This study examined the association between NHHR levels and suicidal ideation using data from the National Health and Nutrition Examination Survey (NHANES), conducted in the United States spanning 2005 and 2016. Calculation of the NHHR corresponds to the proportion of HDL-C to Non-HDL-C. The Patient Health Questionnaire-9's ninth question was implemented for assessing suicidal ideation. Using subgroup analysis, smooth curve fitting, and multivariate logistic regression analysis, the research was conducted. RESULTS Encompassing a cohort of 29,288 participants, the analysis identified that 3.82% of individuals reported suicidal ideation. After using multivariable logistic regression and thorough adjustments, elevated NHHR levels were significantly and positively associated with a heightened likelihood of suicidal ideation, according to the findings (odds ratio [OR] = 1.06; 95% confidence interval [CI]: 1.02-1.11; P = 0.0048). Despite extensive adjustment for various confounding factors, this relationship remained consistent. An inverted U-shaped curve was utilized to illustrate the link between NHHR and suicidal ideation among nonsmokers; the curve's inflection point was situated at 7.80. Subgroup analysis and interaction tests (all P for interaction > 0.05) demonstrated that there was no significant influence of the following variables on this positive relationship: age, sex, race, body mass index, education level, married status, hypertension, diabetes, and smoking status. CONCLUSION Significantly higher NHHR levels were associated with an elevated likelihood of suicidal ideation. Based on these results, it is probable that NHHR may serve as a predictive indicator of suicidal ideation, emphasizing its potential utility in risk assessment and preventive strategies.

Abstract
Cholesterol plays a crucial role in the brain, which suggests that changes in its concentration levels may have an impact on the central nervous system. To examine the association between serum lipid levels and suicidal ideation according to sex, we performed a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey 2014-2018. A total of 13,772 adults 19 years or older were analyzed. The ninth item of the Patient Health Questionnaire was used to evaluate the suicidal ideation of participants. After sorting by sex, a complex logistic regression was performed to measure the association between serum lipid indicators and suicidal ideation. The analysis adjusted for age, body mass index, smoking, heavy drinking, regular exercise, household income, education level, dyslipidemia medication, depression, and chronic diseases. Compared to the intermediated category, the lowest range of low-density lipoprotein cholesterol (LDL-C; <100 mg/dL) was associated with increased suicidal ideation in men (odds ratio [OR] = 1.97; 95% confidence interval [CI]: 1.30-3.01). The association between lipid levels and suicidal ideation was not clear in women. We found an association between lower LDL-C levels and an increased risk of suicidal ideation among Korean men aged 19 years or older.

Abstract
(1) Background: Serum lipid levels affect not only nutritional status but also emotional state. The purpose of this study was to examine the effects of various socio-demographic characteristics, abnormal cholesterol levels, and BMI indicators on depressive symptoms and suicidal ideation in the Korean population. (2) Methods: A total of 23,692 people were surveyed using data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2014, 2016, and 2018. Data from 11,653 patients were analyzed. Age, sex, chronic disease, smoking, alcohol consumption, total cholesterol (HDL, triglycerides), BMI, depression, and suicidal ideation were measured. (3) Results: According to sex, low HDL, high triglycerides, and suicidal ideation were significant, along with low education level, smoking, binge drinking, and high BMI. High triglyceride level was shown to significantly increase the risk of depression in males (OR = 1.535, 95% CI = 1.098–2.147). Factors affecting suicidal ideation in males were age, binge drinking, and depression, while blood lipid factors were not significant. (4) Conclusions: Of the types of serum lipid factors affecting depression and suicidal ideation, high triglycerides were found to be a risk factor for depression in men. Serum lipids can be used as biomarkers to reflect depressive symptoms in men depending on cholesterol level.

Abstract
Cholesterol, the main structural molecule of cell membranes, is involved in essential functions of the human body. Dyslipidemia is an established risk factor for cardiovascular diseases (CVDs) that is observed even in childhood. To reduce the risk of CVDs in children, several clinical guidelines have been published for the management of pediatric dyslipidemia. However, pediatric dyslipidemia is also associated with several health problems other than CVDs. This article reviews the current data on dyslipidemia-related pediatric health issues. There is strong evidence that low serum vitamin D levels, asthma, and mental health problems may be associated with dyslipidemia in the pediatric population regardless of body mass index. This review also highlights the need for further large-scale population-based studies in the Korean pediatric population to establish effective strategies for promoting children's health.

Abstract
INTRODUCTION Previous observational cohort studies showed an association between low serum lipid levels and suicide. This study was undertaken to examine the relationship between lipid parameters and impulsivity in suicidal patients with major depressive disorder (MDD). METHODS The current study included 100 patients with MDD distributed as 50 patients with recent suicidal attempts and 50 patients with no lifetime history of suicide. Participants were subjected to Structured Clinical Interview for DSM-IV Axis I Disorders (SCID I) to confirm the diagnosis. The risk of suicide was assessed through the Suicide Probability Scale (SPS), while the intent and seriousness of suicide were assessed through Beck's Suicidal Intent Scale. assessment of impulsivity was carried out through Barratt Impulsivity Scale. Serum lipid levels were measured in mg/dL after an overnight fast. RESULTS Total cholesterol (TC) was found significantly lower in the suicidal group compared to the non-suicidal depressed group (p = 0.040). Low high-density lipoprotein (HDL) level was significantly correlated with suicidality and high suicide intent was correlated with hopelessness. Logistic regression for lipid profile in both groups revealed significant TC and low-density lipoprotein (LDL) as predictors for suicide. There was no significant correlation between impulsivity and characteristics of depression, suicide probability, suicide intent, and all elements of the lipid profile. CONCLUSIONS Low TC and LDL could predict suicidal behavior in patients with MDD. Impulsivity could not be a mediator or predictor of suicide risk in patients with MDD.

Abstract
Suicides and suicidal behaviors are very important causes of mortality and morbidity and have become a serious global problem. More than 800,000 people die from suicide every year. Previous researches have established that lipids play an important role in the pathogenesis of suicide. Moreover, lipid levels might be a biological marker of suicide. A lot of researchers have tried to identify biological markers that might be related to depressive disorder, bipolar disorder or schizophrenia and suicidal behavior. It was also important to consider the usefulness of an additional tool for prevention actions. Metabolic deregulation, particularly low total cholesterol and low-density lipoproteins-cholesterol levels may cause higher suicide risk in patients with these psychiatric disorders.

Abstract
BACKGROUND Relationships between tumour necrosis factor receptor 2 (TNF-RII), suicidal ideation and levels of serum lipids have not been reported yet. The present study was to explore lipids profiles in Chinese adolescents with different genotypes of TNF-RII rs1061622 and with or without suicidal ideation. METHODS Dietary intakes were surveyed by questionnaires. TNF-RII rs1061622 genotypes were examined by polymerase chain reaction restriction-fragment length polymorphism and verified by DNA sequencing. Lipids levels were examined by routine methods. RESULTS Higher TC/HDL-C levels were observed in the subjects with suicidal ideation than those without suicidal ideation in the male students, but no significant differences were found in the female counterparts. When both TNF-RII rs1061622 and suicidal ideation were considered, although there was no significant difference of suicidal ideation prevalence between the TT homozygotes and the G allele carriers, the G allele carriers had elevated levels of TG and TG/HDL-C compared with the TT homozygotes only in the female subjects with suicidal ideation. The subjects with suicidal ideation had higher TG/HDL-C levels than those without suicidal ideation only in the female G allele carriers. Both suicidal ideation and TNF-RII rs1061622, together with BMI, gender and fat intakes, were found the predictors of TG/HDL-C levels. Different relationship patterns of lipids levels were discovered between male and female subjects with different genotypes and with or without suicidal ideation. CONCLUSIONS Different changes of lipids profiles between the subjects with or without suicidal ideation may result from not only the genders, but also their interactions with TNF-RII rs1061622.

Abstract
BACKGROUND Lipid profile disturbances are frequently observed in major depressive disorder (MDD) and constitute to high mortality rates. However, less is known about whether this risk is present in patients with first-episode MDD. Therefore, this meta-analysis was conducted to examine if lipid parameters differed between healthy controls and first-episode MDD patients. METHODS Cochrane Library, PubMed, PsycINFO, EMBASE, Chinese Journal Net, and WanFang databases were searched from inception to October 23, 2018. The primary outcomes were triglycerides, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and total cholesterol levels. RESULTS A total of 11 case-control studies compared 690 subjects with first-episode MDD and 614 healthy controls were included and analyzed. Compared to healthy controls, patients with first-episode MDD were significantly associated with higher triglyceride (SMD = 0.29, 95% CI: 0.09, 0.48, P = 0.004) and lower HDL cholesterol levels (SMD = -0.54, 95% CI: -0.86, -0.22, P = 0.001). Subgroup analyses revealed that first-episode MDD patients with higher triglyceride and lower HDL levels were found only in Chinese and plasma group when compared to healthy controls (P < 0.05). Meta-regression analysis showed that the significant heterogeneity for triglyceride and HDL cholesterol was partly explained by the quality of study. No significant difference was found in LDL cholesterol and total cholesterol levels between the two groups. LIMITATIONS Heterogeneity was relatively high among the included studies. CONCLUSIONS Elevated triglyceride and decreased HDL cholesterol levels may be associated with first-episode MDD. Findings support early lipid monitoring and interventions targeting healthy lifestyle.

Abstract
BACKGROUND Recently, an emerging group of studies has reported the association between Body Mass Index (BMI) and suicidal ideation in the Western countries. However, this relationship is still unclear with controversial results, and we have little knowledge about this relationship in China which is one of few countries reported higher suicide rates. METHODS This study aims to analyze the association between BMI and suicidal ideation among seniors (≥60 years old) in Shandong, China. A total of 3313 seniors were included in the data analysis. Suicidal ideation, weight, height, socio-demographic and psychological variables were evaluated in this study. Logistic regression was conducted to explore the association between BMI and suicidal ideation among male and female seniors. RESULTS The results showed that 4.2% of the seniors reported suicidal ideation, and 3.4% for men, 4.9% for women. After controlling social-demographic variables, economic status, physical disease, social support and mental health, an inverse relationship between BMI and suicidal ideation was found for men, but not for women. Mental health was still an important factor associated with suicidal ideation. CONCLUSION The results inform health care professors that underweight in male seniors can be associated with higher risk of suicidal ideation in China.

Abstract
BACKGROUND Although many studies have identified factors associated with mood disorder, the association between high-density lipoprotein cholesterol (HDL-C) and mood disorder is still controversial. The aim of our study was to evaluate the association between low HDL-C and onset of mood disorder in Korea based on different cut-off levels. METHODS We used National Health Examinations Service cohort data from 2009 to 2013. We used time-dependent Cox regression analysis to evaluate the association between low level of HDL-C and onset of mood disorder. Hazard ratios (HRs) for onset of mood disorder were estimated for 1- to 2-year time intervals, starting at the first health examination and accounting for the duration until the next health examination. RESULTS A total of 400,803 participants (male: 220,573; female: 180,230) were included in our study. A total of 4576 (2.07%) males and 7598 (4.22%) females developed mood disorder. Based on dyslipidemia (< 40mg/dL), low level of HDL-C was associated with the risk of mood disorder in both male and female, however, only females showed statistically significant (HR: 1.097, 95% CI: 1.012-1.189). Based on quartile-based approach, females with low levels of HDL-C (< 47mg/dL) and males with high levels of HDL-C (≥ 59mg/dL) were associated with subsequent risk of mood disorder. CONCLUSIONS Our findings suggest that level of HDL-C is associated with potential risk factors in mood disorder. However, a flexible threshold value in HDL-C level would be needed to evaluate the subsequent risk of mood disorder. Thus, further studies are needed to help improve the mental health in susceptible individuals.

Abstract
Suicide is a major public health concern and a leading cause of death in most societies. Suicidal behaviour is complex and heterogeneous, likely resulting from several causes. It associates with multiple factors, including psychopathology, personality traits, early-life adversity and stressful life events, among others. Over the past decades, studies in fields ranging from neuroanatomy, genetics and molecular psychiatry have led to a model whereby behavioural dysregulation, including suicidal behaviour (SB), develops as a function of biological adaptations in key brain systems. More recently, the unravelling of the unique epigenetic processes that occur in the brain has opened promising avenues in suicide research. The present review explores the various facets of the current knowledge on suicidality and discusses how the rapidly evolving field of neurobehavioural epigenetics may fuel our ability to understand, and potentially prevent, SB.

Oh J, Kim TS. Serum lipid levels in depression and suicidality: The Korea National Health and Nutrition Examination Survey (KNHANES) 2014. J Affect Disord 2017; 213:51-58. [PMID: 28189965 DOI: 10.1016/j.jad.2017.02.002] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 01/31/2017] [Accepted: 02/04/2017] [Indexed: 10/20/2022]
Abstract
BACKGROUND The level of serum lipids has been reported to be associated with depression and suicidality, but the exact relationship between these factors remains controversial. The aim of this study was to investigate the association between lipid levels and depression with suicidality in large sample. METHODS We examined the association between serum lipid levels and the existence of mild depression measured using Patient Health Questionnaire 9 (PHQ-9) in a national sample of Korean. The data of 2055 men and 2894 women who participated in the 6th Korea National Health and Nutrition Examination Survey (KNHNES VI) were used. The serum concentration of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, and total cholesterol were dichotomized and complex samples logistic regression was employed in the analysis. RESULTS There was a significant association between high level of HDL-C (≥40mg/dl) and depression in adult men, and between high level of triglyceride (≥150mg/dl) and depression in adult women. In middle-aged adults 45-64 year), increased level of depression and suicidality was related to high level of triglyceride, respectively. (depression, OR=2.20 (95% CI 1.26-3.85); suicidality, OR=3.66 (95% CI 1.41-9.51). Furthermore, we found that the increased number of abnormal lipids level was significantly associated with the increased prevalence of depression in women (OR =1.34, 95% CI =1.12-1.60) and in middle-aged adults (OR=1.43, 95% CI =1.12-1.82). LIMITATIONS As this study had a cross-sectional design, it was hard to investigate causation between lipid levels and depression, and the assessment of suicidality needs more validation. CONCLUSION Our findings support a significant association between the high level of HDL-C, triglyceride and depression in large sample data. Triglyceride was highly associated with suicidality in younger and middle-aged adults, but not in elderly adults. Further assessment could delineate relationship between serum lipid levels and depression with suicidality in other ethnic groups.
