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.

Abstract
Background This study aimed to identify socio-demographic, physiologic, and psychologic related factors of the first-time suicide attempt (FSA) in the past 14 days in Chinese adult patients with first-episode drug-naïve (FEDN) major depressive disorder (MDD). Methods A total of 1718 adult patients with FEDN MDD were enrolled in this cross-sectional survey. Depression, anxiety symptoms, and suicide attempts were assessed. Additionally, biological samples were collected and measured, while Logistic regression analysis was employed to explore the risk factors for FSA in the past 14 days among FEDN MDD patients. Results Among suicide attempters, 12.11% (208 out of 1718) reported experiencing FSA in the past 14 days. Logistic regression analysis showed that the risk factors for FSA included more severe anxiety symptoms (OR=1.37, 95%CI: 1.28-1.48, p<0.001), higher levels of total cholesterol (TC) (OR=1.42, 95%CI: 1.13-1.77, p=0.003), and elevated thyroid-stimulating hormone (TSH) (OR=1.13, 95%CI: 1.03-1.25, p=0.01). The regression model exhibited good discriminatory power for FSA with an area under the curve (AUC) of 0.82. Conclusion FEDN MDD patients with more severe anxiety and higher levels of TSH and TC are more likely to develop FSA in the past 14 days. These factors are risk factors for short-term (in the past 14 days) FSA and may serve as indicators for early intervention.

Abstract
OBJECTIVE In patients with major depressive disorder (MDD), the relationship between body mass index (BMI) and risk of suicide attempts (SA) remains unclear, and findings are controversial. The aim of this study was to investigate the relationship between BMI and SA in a Chinese population with first-episode drug-naïve (FEDN) MDD. METHODS A total of 1718 patients with FEDN MDD were enrolled in this cross-sectional study. Their socio-demographic characteristics as well as anthropometric data were collected. The 17-item Hamilton Rating Scale (HAMD-17) and Hamilton Anxiety Scale (HAMA) were used to assess the severity of depression and anxiety symptoms in all participants. Thyroid hormones, lipid profile, and fasting blood glucose (FBG) were measured. A history of suicide attempts was verified based on medical records and interviews with patients and their family members. Multiple logistic regression analysis was used to estimate the association between BMI and the risk of SA. Threshold effects were examined by a two-piecewise logistic regression model. RESULTS Multiple logistic regression analysis showed that BMI was independently and negatively correlated with SA (OR = 0.91, 95%CI: 0.85 to 0.98, P = 0.01) in patients with FEDN MDD after adjusting for covariates. Smoothing plots also revealed a non-linear (L-shaped) relationship between BMI and SA, and a two-piecewise logistic regression model was used to calculate the inflection point of BMI as 22.1 kg/m2. On the left of the inflection point, a negative association between BMI and SA was detected (OR = 0.54, 95%CI: 0.42 to 0.70, P < 0.001), while no significant association was observed on the right side of the inflection point (OR = 1.01, 95%CI: 0.93 to 1.10, P = 0.75). CONCLUSIONS Our results suggest that lower BMI is associated with a higher risk of recent SA in Chinese patients with FEDN MDD, especially in those with BMI below 22.1 kg/m2.

Abstract
BACKGROUND Individuals with major depressive disorder (MDD) are at higher risk for obesity. In turn, weight gain is a predisposing factor for depression. Although clinical data are sparse, suicide risk also appears to be elevated in obese patients. This study used data from the European Group for the Study of Resistant Depression (GSRD) to investigate clinical outcomes associated with body mass index (BMI) in MDD. METHODS Data were drawn from 892 participants with MDD over the age of 18 years (580 female, 50.5 ± 13.6 years). Response and resistance to antidepressant medication, depression rating scale scores, and further clinical and sociodemographic variables were compared using multiple logistic and linear regressions controlled for age, sex, and risk of weight gain due to psychopharmacotherapy. RESULTS Of the 892 participants, 323 were categorized as treatment-responsive and 569 as treatment-resistant. Within this cohort, 278 (31.1 %) were overweight (BMI = 25-29.9 kg/m2) and 151 (16.9 %) were obese (BMI > 30 kg/m2). Elevated BMI was significantly associated with higher suicidality, longer duration of psychiatric hospitalizations over their lifetimes, earlier age of onset of MDD, and comorbidities. There was a trend-wise association of BMI with treatment resistance. LIMITATIONS Data were analyzed in a retrospective, cross-sectional design. BMI was used as an exclusive measure of overweight and obesity. CONCLUSIONS Participants with comorbid MDD and overweight/obesity were at risk for worse clinical outcomes, suggesting that weight gain should be closely monitored in individuals with MDD in daily clinical practice. Further studies are needed to explore the neurobiological mechanisms linking elevated BMI to impaired brain health.

Abstract
BACKGROUND Both fatal and nonfatal suicidal behaviours are important complications of mental, neurological, and substance use disorders (MNSDs) worldwide. We aimed at quantifying the association of suicidal behaviour with MNSDs in Low and Middle Income Countries (LMICs) where varying environmental and socio-cultural factors may impact outcome. METHODS We conducted a systematic review and meta-analysis to report the associations between MNSDs and suicidality in LMICs and the study-level factors of these associations. We searched the following electronic databases: PUBMED, PsycINFO, MEDLINE, CINAHL, World Cat, and Cochrane library for studies on suicide risk in MNSDs, with a comparison/control group of persons without MNSDs, published from January 1, 1995 to September 3, 2020. Median estimates were calculated for relative risks for suicide behaviour and MNSDs, and when appropriate, these were pooled using random effects metanalytic model. This study was registered with PROSPERO, CRD42020178772. RESULTS The search identified 73 eligible studies: 28 were used for quantitative synthesis of estimates and 45 for description of risk factors. Studies included came from low and upper middle-income countries with a majority of these from Asia and South America and none from a low-income country. The sample size was 13,759 for MNSD cases and 11,792 hospital or community controls without MNSD. The most common MNSD exposure for suicidal behaviour was depressive disorders (47 studies (64%)), followed by schizophrenia spectrum, and other psychotic disorders (28 studies (38%)). Pooled estimates from the meta-analysis were statistically significant for suicidal behaviour with any MNSDs (odds ratios (OR) = 1∙98 (95%CI = 1∙80-2∙16))) and depressive disorder (OR = 3∙26 (95%CI = 2∙88-3∙63))), with both remaining significant after inclusion of high-quality studies only. Meta-regression identified only hospital-based studies (ratio of OR = 2∙85, CI:1∙24-6∙55) and sample size (OR = 1∙00, CI:0∙99-1∙00) as possible sources of variability in estimates. Risk for suicidal behaviour in MNSDs was increased by demographic factors (e.g., male sex, and unemployment), family history, psychosocial context and physical illness. INTERPRETATION There is an association between suicidal behaviour and MNSDs in LMICs, the association is greater for depressive disorder in LMICs than what has been reported in High Income Countries (HICs). There is urgent need to improve access for MNSDs care in LMICs. FUNDING None.

Abstract
The factors associated with suicide attempts in major depressive disorder (MDD) patients with comorbid glucose disturbances remain unclear. To the best of our knowledge, this is the first study with a large sample size to examine risk factors of suicide attempts in first-episode drug-naïve (FEDN) MDD patients with comorbid glucose disturbances, including clinically relevant factors, metabolic parameters, and thyroid hormone levels. A total of 1718 FEDN MDD patients were enrolled. The Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), and Positive and Negative Syndrome Scale (PANSS) were used to assess the clinical symptoms of patients. Fasting blood glucose, metabolic parameters, and thyroid hormone levels were measured. After controlling for HAMA and HAMD scores, the suicide attempt rate was 1.88 times higher in MDD patients with glucose disturbances than in MDD patients without glucose disturbances. Compared to non-suicide attempters, suicide attempters among the MDD patients with glucose disturbances had higher scores on HAMD and HAMA, PANSS positive symptoms, as well as higher levels of systolic and diastolic blood pressure, TC, LDL-C, thyroid stimulating hormone (TSH), TgAb, and thyroid peroxidases antibody (TPOAb). The combination of positive symptom score, HDL-C, systolic blood pressure, and marital status distinguished suicide attempters from non-suicide attempters. In addition, HAMA score, HAMD score, and TPOAb were associated with the number of suicide attempts in MDD patients with comorbid glucose disturbances. Our results suggest a high incidence of suicide attempts in MDD patients with comorbid glucose disturbances. Several clinically relevant factors, metabolic parameters, and thyroid hormone function have an impact on suicide attempts in MDD patients with comorbid glucose disturbances.

Abstract
OBJECTIVE A systematic review of literature was conducted to determine the association between serum lipids and suicidality in people with schizophrenia spectrum disorders. METHODS We undertook a systematic search of multiple databases for studies that ascertained an association between serum lipids and suicidality in adult patients with schizophrenia spectrum disorders (18-65 years) from database inception to 2 September 2020. Qualitative analysis was done using National Institute of Health (NIH) scales. The standard mean difference (SMD) and 95% confidence intervals (CI) were calculated for each study and standardized relative to the study. Adjusted p-value, Z-test, and heterogeneity were calculated, as well as testing for publication bias. RESULTS Of 1262 records identified, 17 studies (n = 3113) were included in our systematic review, while 11 studies were included in the meta-analysis. The majority of studies (11) rated fair on qualitative analysis. Data from seven studies (n = 1597) revealed a medium effect size for an association between low total cholesterol and suicide attempts (SMD -0.560; 95% CI: 0.949-0.170; p = 0.005). People with history of suicide attempt had a mean cholesterol value 0.56 SD lower than the mean in those without suicide attempts. There were differences in how a suicide attempt was defined and there was high heterogeneity (I2 = 83.3%). No significant association was found between any of the serum lipid parameters and suicide ideation. Funnel-plot analysis suggested small study effects with publication bias. CONCLUSIONS Suicide attempts in people with schizophrenia spectrum disorders are associated with low mean total cholesterol levels.

Abstract
BACKGROUND Prior studies have established inconsistent associations between body weight and mental health. However, most work has relied on body mass index (BMI) and examination of a single mental health variable. The present study examined associations of BMI and waist circumference with multiple mental health variables in a transdiagnostic psychiatric sample. METHODS Nursing staff measured waist circumference and calculated the BMI of 742 adults (54.6% female, 45.4% male) presenting for psychiatric treatment. Participants completed the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), Behavior and Symptom Identification Scale (BASIS-24), and Mental Health Continuum-Short Form (MHC-SF) as part of standard clinical monitoring. Suicide risk was assessed using the clinician-administered Mini International Neuropsychiatric Interview (M.I.N.I.). For curve fit estimation regression models, we entered BMI and waist circumference as independent variables separately; we entered seven dependent variables separately: 1) depression, 2) anxiety, 3) substance use, 4) self-harm, 5) interpersonal functioning, 6) well-being, and 7) suicide risk. RESULTS Increased BMI was associated with decreased well-being and increased depression. Increased waist circumference was associated with worse interpersonal functioning. Non-linear (quadratic) associations were observed between weight and depression, substance use, self-harm, and suicide. LIMITATIONS Most of the sample was White and only 2.6% was in the underweight category, limiting broad applicability of findings. Cross-sectional design precludes causal attributions. CONCLUSIONS Given associations between well-being, depression, interpersonal functioning, substance use, self-harm, and suicide with weight, findings may be used to inform mental health treatment, particularly by tailoring interventions to high-risk weight categories (underweight, obese) in psychiatric populations.

Abstract
The potential correlation between serum lipid profiles and suicidal tendencies has been previously reported, however, it is unclear whether serum lipid profiles have definite relevance to recently attempted suicides in individuals suffering from major depressive disorder (MDD). In this study, the relationship between blood lipids and suicide attempts in first-episode MDD patients in research were used to examine whether there is a connection. The cross-sectional study recruited 580 patients at the time of their first episode, measuring up to the diagnostic standard of MDD. Baseline demographic, clinical data, and blood lipid level data were collected. Depression severity was measured with the Hamilton Depression Rating Scale (HAMD). Our results revealed that the level of TC may be identified as a promising and effective biomarker for first-episode MDD suicide risk, suggesting that screening of serum lipid profiles in depressive patients is essential for suicide prevention.

Abstract
BACKGROUNDS Major depressive disorder is an ordinary mental disorder, and suicide is considered to be a major concern among patients with MDD. Previous studies focused on the relationship between suicide attempts and metabolism in elderly patients with MDD, while ignore the young people. The aim of this study is to find the potential relationship between suicide attempts and metabolism in young patients with MDD to find a way to prevent and ultimately reduce suicide in young patients with MDD. METHODS Cross-sectional design was employed in the study.740 patients aged between 18 and 45 years old with MDD had been consecutively recruited in this study between 2011 and 2017, 128 of whom had suicide attempts. Their serum samples used to monitor fasting blood glucose, serum lipids as well as socio-demographic characteristics were collected. Besides, some clinical scales were also employed to measure symptoms of anxiety, depression and other conditions. RESULTS This study indicated that compared with non-suicide attempters, suicide attempters in young patients with MDD showed higher levels of FBG, TC, LDL-C (all p < 0.05) and lower levels of HDL-C(p < 0.001). Further logistic regression analysis suggested that suicide attempts were associated with increased FBG, decreased HDL-C, the course of disease, HAMD scores and obvious anxiety. CONCLUSIONS Suicide attempts in young patients with MDD may be predicted by metabolic levels in the future. And our findings suggested that the level of FBG and HDL-C can be promising biomarkers to predict the occurrence of this event.

Abstract
Several studies have reported a link between lipid disorders and suicidality. However, few studies have investigated the relationship between suicidal behavior and blood lipid profiles in patients with first-episode and drug-naive (FEDN) major depressive disorder (MDD). The main purpose of this study was to examine the relationship between plasma lipid profiles and suicide attempts in a large sample of FEDN MDD patients in the Chinese Han population, which has not been reported. A total of 1,718 MDD outpatients were recruited. Their clinical and demographic data as well as plasma lipid parameters were collected. We obtained suicide attempt data through interviews with patients and their family members. We rated the Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) for all patients. The suicide attempt rate of MDD patients was 20.14%, of which 13.68% in the last month and 6.46% in the past. Further, compared with non-attempters, suicide attempters had significantly higher total levels of cholesterol (TC) and low-density lipoprotein cholesterol (LDL-c), higher HAMA and HAMD scores, but significantly lower high-density lipoprotein cholesterol (HDL-c) levels. Logistic regression analysis showed that suicide attempts were correlated with higher TC, lower HDL-c, and higher HAMA and HAMD scores with the adjusted odds ratio (OR) of 1.35, 0.52,1.28, and 1.08, respectively (all p < 0.05). Our findings suggest that FEDN patients with MDD have a high rate of attempted suicide. In the early stage of MDD patients, certain blood lipid parameters and more severe symptoms of anxiety and depression are correlated with suicide attempts. However, due to the cross-sectional design of this study, it is impossible to draw a causal relationship between lipid profiles and suicide attempts. Moreover, an inverse correlation can also be considered, that is, high cholesterol may be the consequence of suicide attempts and depression.

Abstract
AIMS Death ideation (thinking about/wishing for one's own death, thinking that one would be better off dead) is linked to an increased mortality risk. However, comparatively little is known about more general thoughts of death (GTOD) where no wish to die or life value is expressed. This study examined whether GTOD predicted mortality in a community-based cohort of older adults. METHODS Data came from the Komo-Ise cohort study in Gunma prefecture, Japan. The analytic sample comprised 8208 individuals (average age 61.3 (range 47-77)) who were asked in wave 2 of the study in 2000 if they had 'Thought about death more than usual, either your own, someone else's or death in general?' in the past 2 weeks. Death data were obtained from the municipal resident registration file. Cox proportional hazards regression analysis was used to examine associations. RESULTS During the follow-up period (2000-2008), there were 672 deaths. In a model adjusted for baseline covariates, GTOD were significantly associated with all-cause mortality (hazards ratio 1.66, 95% confidence interval 1.20-2.29). Stratified analyses showed an association between GTOD and mortality in men, older subjects (⩾70 years), married individuals and those with higher social support. CONCLUSIONS GTOD are associated with an increased mortality risk among older citizens in Japan. Research is now needed to determine the factors underlying this association and assess the clinical relevance of screening for GTOD in older individuals.

Abstract
BACKGROUND Studies have examined associations between obesity and suicide. However, the overall outcomes of the studies are not fully elucidated, and the orientation of these studies needs to be identified. The aim of this systematic review and meta-analysis was to determine the suicide risk based on body mass index (BMI). METHODS The authors systematically searched PubMed, Scopus, PsycInfo and Google Scholar databases until December 2017. After the screening process, 15 prospective studies were included in meta-analysis. Stata-14 was used for meta-analysis. Forest Plot was calculated for the whole of the 15 studies and the subgroups; publication bias was examined as well. RESULTS In obesity group, Pooled Risk Ratio (RR) was achieved for suicide mortality (RR = 0.67; 95% confidence interval (CI) CI = 0.54-0.81) and suicidal ideation (RR = 1.50; 95% CI = 0.76-2.23). It was also measured in overweight group, for suicide mortality (RR = 0.78; 95% CI = 0.71-0.85) and suicidal ideation (RR = 1.17; 95% CI = 0.65-1.69). CONCLUSION Overall, there is an inverse association between obesity and overweight with suicide mortality and attempted suicide, and positive association between obesity and overweight with suicidal ideation. There was no evidence of publication bias. Overall, our findings indicate the role of BMI in suicide.

Abstract
BACKGROUND Cholesterol has been associated as a risk factor for cardiovascular disease. Recently, however, there is growing evidence about crucial requirement of neuron membrane cholesterol in the organization and function of the 5-HT1A serotonin receptor. For this, low cholesterol level has been reported to be associated with depression and suicidality. However there have been inconsistent reports about this finding and the exact relationship between these factors remains controversial. Therefore, we investigated the link between serum cholesterol and its fractions with depression disorder and suicide attempt in 467 adult subjects in Mexican mestizo population. METHODS Plasma levels of total cholesterol, triglycerides, and high-density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) were determined in 261 MDD patients meeting the DSM-5 criteria for major depressive disorder (MDD), 59 of whom had undergone an episode of suicide attempt, and 206 healthy controls. RESULTS A significant decrease in total cholesterol, LDL-cholesterol, VLDL-cholesterol and triglyceride serum levels was observed in the groups of MDD patients and suicide attempt compared to those without suicidal behavior (p < 0.05). After adjusting for covariates, lower cholesterol levels were significantly associated with MDD (OR 4.229 CI 95% 2.555 - 7.000, p<.001) and suicide attempt (OR 5.540 CI 95% 2.825 - 10.866, p<.001) CONCLUSIONS: These results support the hypothesis that lower levels of cholesterol are associated with mood disorders like MDD and suicidal behavior. More mechanistic studies are needed to further explain this association.

Abstract
OBJECTIVE Due to the increased prevalence of liver disease in patients with bipolar disorder, we examined the potential role of the patatin-like phospholipase domain-containing protein 3 (PNPLA3) variant among individuals with bipolar disorder and those with no mood disorder. METHODS We used the National Health and Nutrition Examination Survey (NHANES) database (aged 15-39 years) to identify a group of individuals with a bipolar diagnosis and a control group of individuals with no mood disorder. A total of 1931 individuals were randomly selected, one from each family containing information on the PNPLA3 genotype to be used in the analysis. RESULTS Analyses revealed individuals with the recessive variant genotype (MM) had an adjusted odds ratio for bipolar disorder of about 4.6 compared to individuals with either IM or II genotypes of the PNPLA3 variant. LIMITATIONS AND CONCLUSIONS Limitations of this study include the use of a lay-administered survey in for diagnosis of bipolar disorder in NHANES. The association between the PNPLA3 variant and bipolar disorder may help guide further work on medication effectiveness, treatment options, prevention approaches, and understanding potential medication side effects among specific subgroups of individuals with the MM genotype.

Abstract
BACKGROUND Previous research suggests a relationship between weight and depression/suicidality, although few studies have examined the mechanisms underlying this association. This study examined the mediating role of self-esteem in the relationship between BMI and depression/suicidality, as well as the moderating role of gender in the mediated pathways. METHODS As part of a screening process in consideration for bariatric surgery, 3,101 adults (81.4% female, 18.6% male) were assessed one time. Five univariate mediation and five univariate moderated-mediation models were hypothesized and analyzed. For the mediation models, we entered five outcome variables separately: 1) severity of depressed mood, 2) diagnosis of Major Depressive Disorder, 3) lifetime history of suicide attempts, 4) suicidal ideation at the time of evaluation, and 5) severity of suicidality, BMI as the independent variable, and self-esteem as the mediator. For the moderated-mediated models, gender was examined as a moderator to examine whether self-esteem was a stronger mediator for one gender, compared to the other. RESULTS Findings supported the mediating role of self-esteem across all five outcomes. Further, the mediated effect was moderated by gender, such that the mediation effect was stronger for males, compared to females. LIMITATIONS The majority of the sample consisted of White females, limiting broad applicability of findings. All variables were assessed simultaneously, at baseline, limiting the ability to make causal attributions. CONCLUSIONS Study findings suggest that self-esteem may help explain the relationship between BMI and depression/suicidality, particularly for men. Thus, interventions targeting self-esteem may be useful for improving psychological outcomes among those presenting for bariatric surgery.

Abstract
Public health concerns for the independent management of obesity and suicidal behavior are rising. Emerging evidence suggests body weight plays an important role in quantifying the risk of suicide. In light of these findings, we aimed to clarify the association between body mass index (BMI) and suicidal behavior by systematically reviewing and evaluating the literature. Studies were identified by searching MEDLINE, EMBASE, PsycINFO, and CINAHL from inception to January 2015, supplemented by hand and grey literature searches. Study screening, data extraction, and risk of bias assessment were conducted in duplicate. We included 38 observational studies. Meta-analyses supported an inverse association between BMI and completed suicide. Pooled summary estimates demonstrated that underweight was significantly associated with an increased risk of completed suicide (HR = 1.21, 95% CI 1.07 to 1.36, p = .002), and obesity (HR = 0.71, 95% CI 0.56 to 0.89, p = .003) and overweight (HR = 0.78, 95% CI 0.75 to 0.82, p < .0001) were significantly associated with a decreased risk of completed suicide relative to normal weight. A qualitative summary of the literature demonstrated conflicting evidence regarding the association between BMI and attempted suicide and revealed no association between BMI and suicidal ideation. BMI may be used to aid the assessment of suicide risk, especially that of completed suicide. However, unmeasured confounders and systematic biases of individual studies limit the quality of evidence.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis to determine the association between serum lipid levels and suicidality, as evidence from previous studies has been inconsistent. METHODS We identified relevant studies by searching Medline, Web of Science, EMBASE, and the Cochrane Database of Systematic Reviews (1980 to Dec. 5, 2014). Studies assessing the association between serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and/or triglycerides (TG) levels and suicidality were included. We used a random-effects model to take into account heterogeneity among studies. RESULTS We included 65 studies with a total of 510 392 participants in our analysis. Compared with the nonsuicidal patients, suicidal patients had significantly lower serum TC (weighted mean difference [WMD] -22.35, 95% confidence interval [CI] -27.95 to -16.75), LDL-C (WMD -19.56, 95% CI -26.13 to -12.99) and TG (WMD -23.40, 95% CI -32.38 to -14.42) levels, while compared with the healthy controls, suicidal patients had significantly lower TC (WMD -24.75, 95% CI -27.71 to -21.78), HDL-C (WMD -1.75, 95% CI -3.01 to -0.48) and LDL-C (WMD -3.85, 95% CI -7.45 to -0.26) levels. Furthermore, compared with the highest serum TC level category, a lower serum TC level was associated with a 112% (95% CI 40%-220%) higher risk of suicidality, including a 123% (95% CI 24%-302%) higher risk of suicide attempt and an 85% (95 CI 7%-221%) higher risk of suicide completion. The cut-off values for low and high serum TC level were in compliance with the categories reported in the original studies. LIMITATIONS A major limitation of our study is the potential heterogeneity in most of the analyses. In addition, the suicidal behaviour was examined using different scales or methods across studies, which may further explain heterogeneity among the studies. CONCLUSION We identified an inverse association between serum lipid levels and suicidality. More mechanistic studies are needed to further explain this association.

Abstract
BACKGROUND Suicide is among the leading causes of death worldwide. Suicide attempts and suicidal ideation are more common than completed suicide and are associated with psychological distress. These behaviors are considered risk factors of completed suicide. Considering the psychosocial stigma and medical comorbidities associated with obesity, an accumulating body of studies have investigated body mass index (BMI) as a potential risk factor of suicide. However, several cohort studies have demonstrated an inverse relationship between BMI and completed suicide, suggesting a protective effect of increasing BMI against completed suicide. The association between BMI and attempted suicide is more equivocal, with several studies reporting both positive and negative relationships between BMI and attempted suicide. The primary objective of this study is to systematically review the literature to determine the association between BMI and suicidal behavior (including completed suicide, attempted suicide, suicidal ideation) in an adult population (18 years and older). The secondary objective is to explore whether sex, age, and the method used in suicide modify the relationship between BMI and suicidal behavior. METHODS/DESIGN An electronic search will be conducted using PubMed/MEDLINE, PsycINFO, CINAHL, and EMBASE using a predefined search strategy; databases will be searched from their inception. Two authors (SP and RE) will independently screen articles using predefined inclusion and exclusion criteria and will extract pertinent data using a pilot tested extraction form. At all levels of screening, discrepancies between the two authors will be resolved by consensus, and in the case of disagreement, by consulting a third author (ZS). The primary outcomes include the association between BMI and completed suicide, attempted suicide, and suicidal ideation. If appropriate, a meta-analysis will be conducted. Risk of bias and quality of evidence will be assessed. DISCUSSION The results of this systematic review will inform health care professionals and researchers about whether BMI has a significant role in suicidal behavior and psychological well-being.

Abstract
There are inconsistent reports showing that the relationship between total cholesterol (TC) level and suicidality might be gender-specific. We compared 30 first-episode schizophrenia (FES) patients reporting suicidal ideation based on the Operational Criteria for Psychotic Illness (OPCRIT) checklist with 70 FES patients, who have never experienced suicidal ideation. After controlling for potential confounders, higher TC was associated with suicidal ideation only in FES females. Future studies should disentangle biological underpinnings of this gender-specific association.

Abstract
INTRODUCTION Evidence for a possible association between a low level of cholesterol and increased suicidal behaviour has accumulated in the recent 3 decades. The present study investigates whether lipid levels can make state-dependent markers of suicidal behaviour in Polish patients with mood disorder recently admitted to a psychiatric hospital owing to an acute depressive episode. MATERIALS AND METHODS The study was conducted on 223 patients (73 male and 150 female) with unipolar (n=171) and bipolar (n=52) depression. They were interviewed to assess any occurrence of suicidal thoughts, suicidal tendencies and/or suicidal attempts during the 3 months before admission. Laboratory measurements [total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides and total lipids] were obtained within 24-72 h after hospital admission. RESULTS Suicidal thoughts, tendencies, and attempts were associated with low total cholesterol, LDL cholesterol, and total lipids in both male and female patients, in both diagnostic categories. Triglycerides were significantly lower in male and female patients with suicidal thoughts compared with their non-suicidal counterparts. No association with suicidality was found with HDL cholesterol. CONCLUSIONS The results of our study support a majority of research showing the association in depressed patients between suicidal behaviour and low levels of total and LDL cholesterol. In addition, the data suggest a similar association with low total lipids, and in some instances, with low triglycerides.

Abstract
OBJECTIVES Examining the associations between health and lifestyle factors recorded in the participants' early teens and development of suicidal thoughts recorded 4 years later. DESIGN Population-based prospective cohort study. SETTINGS All students in the two relevant year classes in Nord-Trøndelag County were invited, 80% attended both waves of data collection. PARTICIPANTS 2399 secondary school students who participated in the Young-HUNT1 study in 1995-1997 (13-15 years old) were included in a follow-up study 4 years later (17-19 years old). PRIMARY OUTCOME MEASURE Suicidal thoughts reported at age 17-19 years. RESULTS 408 (17%, 95% CI 15.5% to 18.5%) of the adolescents reported suicidal thoughts at follow-up, 158 (14.2%, CI 13.6% to 16.4%) boys and 250 (19.5%, CI 18.8% to 22.0%) girls. Baseline anxiety and depressive symptoms (adjusted OR (aOR) 1.9, CI 1.4 to 2.6), conduct problems (aOR 1.8, CI 1.3 to 2.6), overweight (aOR 1.9 CI 1.4 to 2.4), and muscular pain and tension (aOR 1.8, CI 1.4 to 2.4), were all associated with reporting suicidal thoughts at follow-up. CONCLUSIONS One in six young adults experienced suicidal thoughts, girls predominating. Suicidal thoughts were most strongly associated with symptoms of anxiety/depression, conduct problems, pain/tension and overweight reported when participants were 13-15 years old. Specific preventive efforts in these groups might be indicated. Future research should investigate whether similar associations are seen with suicide/suicidal attempts as endpoints.

Abstract
BACKGROUND Low cholesterol levels have been found to be associated with a wide range of behavioral problems, including violent and criminal behavior, and a wide range of psychological problems including impulsivity, depression, and other internalizing problems. The casual mechanisms underlying these associations remain largely unknown, but genetic factors may play a role in the etiology of such associations as previous research has found significant genetic influence on cholesterol levels and various deleterious behavioral and psychological outcomes. The current study addressed this existing gap in the literature by performing a genetically sensitive test of the association between cholesterol levels and various outcomes including levels of self-control, depressive symptoms, anger expression, and neuroticism. METHODS DeFries-Fulker (DF) analysis was used to analyze data from 388 twin pairs nested within the Survey of Midlife Development in the United States (MIDUS). RESULTS The results of the genetically informed models revealed that high-density lipoprotein (HDL) cholesterol levels were negatively and significantly associated with depressive symptoms, had a marginally significant effect on neuroticism, and a nonsignificant effect on both anger expression and self-control. LIMITATIONS The findings may not extrapolate to the larger population of American adults since the subsample of twins with cholesterol information may not be nationally representative. CONCLUSIONS Genetic influences play a significant role in the association between cholesterol levels and various deleterious outcomes and failing to control for these influences may result in model misspecification and may increase the probability of detecting a significant association when one does not actually exist.

Abstract
OBJECTIVE Metabolic syndrome (MetS) is reportedly associated with mental disorders that are known to increase the risk of suicide. However, it is not known whether this association is independent of other risk indicators of suicide. This study therefore investigated whether metabolic abnormalities increase the risk of suicide during a 10-year follow-up period. METHODS This prospective study enrolled participants from a community-based integrated screening samples cohort in Taiwan. Of the 76,297 people recruited for this study, 12,094 had MetS at baseline. The independent variables were MetS and its components such as high blood pressure and high blood lipid levels. The outcome was death from suicide (n = 146). RESULTS MetS was associated with an increased risk of suicide risk by 16% per MetS component (95% confidence interval [CI] = 1%-33%), adjusting for demographics, life-style factors, and clinical correlates. Of the five MetS components, elevated blood pressure was independently associated with suicide-related mortality (adjusted hazard ratio [aHR] = 1.49, 95% CI = 1.03-2.15). CONCLUSIONS This analysis of community-based longitudinal data showed that MetS and its components, particularly elevated blood pressure, correlated positively with suicide risk after controlling other factors. Therefore, public mental health interventions targeting suicide reduction may need to specifically focus on individuals with hypertension and other components of the MetS.

Abstract
INTRODUCTION Obesity has been associated with an elevated risk of depression and other mental health symptoms. An increasing number of robust prospective studies, however, counter-intuitively and consistently suggested that body mass index (BMI) was inversely associated with the risk of completed suicide in a dose-response fashion. The current contribution appraised the epidemiological evidence and examined the nature of the purported relationship. METHOD We conducted a systematic review of English publications of original studies using the terms "obesity", "overweight", "body mass index", "BMI", "attempted suicide", "completed suicide", "suicide ideation", "suicidal behaviors" and "suicide". Data were extracted primarily through MEDLINE and PUBMED databases. RESULTS Almost all cohort studies reported an inverse relationship between BMI and the risk of completed suicide irrespective of region of origin and the gender of study participants. Overall, among men, a high BMI was associated with a low risk of attempted or completed suicide. There was a paradox among women, namely, a high BMI was associated with an elevated risk of attempted suicide but a low risk of completed suicide. LIMITATIONS As a narrative review, the current report was interpretive and qualitative in nature. CONCLUSION Consideration of observational data, methodological issues stemmed from the rarity of deaths by suicide, homogeneity of study populations, heterogeneity of suicide methods, and the corresponding neurobiological changes made interpretation difficult. Intercultural cohort observations across countries may help to weigh the contributions from biological and socio-cultural factors. The purported association not only represents a scientific challenge, it's also an opportunity potentially leading to important insights into prevention of suicide death.

Abstract
BACKGROUND There is evidence from prospective studies that obesity is positively associated with depression. In contradiction to this, however, a number of studies have revealed that the number of completed suicides decreases with increasing BMI. The objective of this systematic review is to elucidate this ambiguous research field, providing an overview of literature examining the relationship between obesity and risk of suicide in adults (>18 years). METHODS Literature searches of the databases PubMed/Medline, PsychInfo, and Web of Sciences were conducted. Fifteen studies concerning completed suicide, suicide attempts and suicidal ideation met the inclusion criteria (seven prospective and eight cross-sectional studies). RESULTS Eight studies evaluating completed suicide reported an inverse relationship between BMI and suicide, meaning that obese people are less likely to commit suicide than people of low or normal weight, whereas one study showed no association and one showed a positive association. Studies about suicide attempts and ideation, on the other hand, found results that differed depending on gender. While obese woman reported more suicide attempts and suicidal ideation, obese men reported less attempts and thoughts. DISCUSSION The role of confounding variables such as age or psychiatric illness on suicide risk are discussed and remaining research questions are outlined, especially regarding the role of different underlying biological pathways and consideration of different classes of obesity.

Abstract
OBJECTIVE To examine the associations between body mass index (BMI) and incidence rate (IR) of suicide attempt and suicide. DESIGN AND METHODS 849,434 British adults were identified from The Health Improvement Network (THIN) database between January 2000 and October 2007. BMI was categorized into six levels: <18.5 (underweight), 18.5-24.9 (normal weight), 25.0-29.9 (overweight), 30.0-34.9, 35.0-39.9, and ≥40 (obese levels I-III). RESULTS We identified 3,111 suicide attempts by Read codes and 75 suicides with medical records. The overall IR of suicide attempt was 82.2 cases per 100,000 person-years. The IR decreased with BMI in men with depression (471.3-166.0 cases per 100,000 person-years, P for trend = 0.02) and in men without depression (241.5-58.0 cases per 100,000 person-years, P for trend < 0.0001). In women with depression, an L-shaped relationship was observed, that is, a higher rate in underweight group when compared with reference group (503.2 vs. 282.7 per 100,000 person-years) and no significant differences in others (231.8-195.5 cases per 100,000 person-years). In women without depression, the IR was U-shaped with BMI (125.2 in underweight, 68.6 in reference, and 48.5-79.9 cases in overweight and obese I-III groups per 100,000 person-years, P for trend < 0.0001). The above trends remained after adjustment for the covariates. Regarding suicide, the overall IR was 2.0 cases per 100,000 person-years, which tended to decrease with BMI (P = 0.14). CONCLUSIONS We concluded an inverse linear association between BMI and suicide attempt among men, an L-shaped association in nondepressive women, and a U-shaped association in depressive women were observed. The study also suggested an inverse linear tendency between BMI and suicide.

Abstract
OBJECTIVE The relationship between obesity and suicidal ideation and behavior (suicidality) is not well understood, and conventional suicide risk factors do not adequately explain the associations observed. Thus, the current study aimed to further examine the relationship between body mass index (BMI; kg m(-2)) and suicidal ideation as well as potential mechanisms of this relationship. METHODS Two hundred seventy-one adults (n=151 undergraduates; n=120 obesity treatment participants) completed self-report questionnaires assessing relevant variables, including suicidal ideation, perceived burdensomeness, thwarted belongingness and current height/weight used to calculate BMI. RESULTS There was a significant, quadratic relationship between BMI and suicidal ideation (b=0.001, t=2.21, P=0.03, partial r=0.14) and between BMI and perceived burdensomeness (b=0.003, t=2.50, P=0.013, partial r=0.16), such that as BMI increased, these positive associations became more pronounced. Additionally, perceived burdensomeness partially mediated the relationship between BMI and suicidal ideation. CONCLUSIONS Individuals with a higher BMI demonstrated increased suicidal ideation as well as greater feelings of perceived burdensomeness. These results provide novel information regarding potential mechanisms explaining the obesity-suicidal ideation association.

Abstract
Cholesterol is a core component of the central nervous system, essential for the cell membrane stability and the correct functioning of neurotransmission. It has been observed that cholesterol may be somewhat associated with suicidal behaviours. Therefore, the aim of this paper was to elucidate current facts and views about the role of cholesterol levels in mood disorders. The majority of the studies reviewed in the present paper suggest an interesting relationship between cholesterol (especially lower levels) and suicidality. On the other hand, particularly during the last years, relationships between serum cholesterol and suicidality were doubted on the basis of some recent studies that have not found any correlation. However, the debate on relationships between cholesterol and suicide is open and longitudinal studies on a larger sample of patients are needed to further clarify this important issue.

Abstract
OBJECTIVE Bipolar disorder is associated with a high risk of suicide. Many clinical characteristics and, recently, biomarkers have been studied with the aim to find useful predictors of suicidality. The role of serum lipids has also been explored albeit with conflicting results; however, few studies have been focused on patients with bipolar disorder. Aim of our study is to investigate whether serum cholesterol, triglycerides, HDL-c and metabolic syndrome are associated with lifetime suicide attempts in a large naturalistic sample of patients with bipolar disorder. METHODS 220 patients with bipolar disorder were included. History of lifetime suicide attempts was systematically and retrospectively assessed for each patient. Blood exams testing total cholesterol, triglycerides, and HDL-c levels were performed, and metabolic syndrome was diagnosed according to NCEP ATP-III modified criteria. Serum lipid levels and metabolic syndrome were compared in patients with or without history of suicide attempt. According to a theory that links impulsivity and violence with low cholesterol, the association between lipid levels and violent suicidal behavior was also assessed. RESULTS Lifetime suicide attempts rate was 32.3%. There were no statistically significant differences between patients with and without lifetime suicide attempts in cholesterol, triglycerides, HDL-c levels, and the prevalence of metabolic syndrome. No differences in the same variables were found in violent suicide attempters compared with nonviolent ones. Clinical characteristics such as gender, low education, higher number of manic and depressive episodes, and taking more medications for bipolar disorder were associated with lifetime suicide attempts. CONCLUSIONS Our results do not support the hypothesis of a strong association between serum lipid levels and suicide in patients with bipolar disorder.

Abstract
Recent studies in Western nations have shown inverse associations between body mass index (BMI, measured as weight (kg)/height (m)(2)) and suicide. However, it is uncertain whether the association is similar in non-Western settings, and the biologic pathways underlying the association are unclear. The authors investigated these issues in a cohort of 542,088 Taiwanese people 20 years of age or older who participated in a health check-up program (1994-2008); there were 573 suicides over a mean 8.1 years of follow up. There was a J-shaped association between BMI and suicide risk (P for the quadratic term = 0.033) but limited evidence of a linear association (adjusted hazard ratio per 1-standard-deviation increase = 0.95 (95% confidence interval: 0.85, 1.06)); compared with individuals whose BMI was 18.5-22.9, adjusted hazard ratios for those with a BMI <18.5 or ≥35 were 1.56 (95% confidence interval: 1.07, 2.28) and 3.62 (95% confidence interval: 1.59, 8.22), respectively. A high waist-to-hip ratio was associated with an increased risk of suicide. There was some evidence for a reverse J-shaped association of systolic blood pressure and high density lipoprotein cholesterol with suicide and an association of higher triglyceride level with increased suicide risk; these associations did not appear to mediate the associations of BMI and waist-to-hip ratio with suicide.

Abstract
The role of elevated serum triglyceride level as a risk factor of coronary artery disease is well established. Previous results have also indicated that depression or depressive symptoms and vital exhaustion correlate with triglyceride levels. The aim of this study was to investigate the associations of depressive symptoms, vital exhaustion, and health behavior with serum triglyceride levels. The study sample comprised 444 high-risk middle-aged men. Participants completed self-report questionnaires before laboratory tests. Triglyceride concentrations were measured by the enzymatic method. Vital exhaustion and depression were associated with unhealthy lifestyles and triglycerides. Vital exhaustion and depression were closely correlated constructs with comparable relations with known coronary artery disease risk factors. When comparing vital exhaustion (VE) to Beck Depression Inventory (BDI), however, the first one had a stronger correlation with triglycerides (TG), and also, path analyses showed a direct link from vital exhaustion to body mass index but not from depression. Both vital exhaustion and depression are related to triglyceride levels. The relations are partly mediated by unfavorable lifestyles. Although vital exhaustion is not so commonly assessed as depression, results of this study support the importance of vital exhaustion as a health-related psychological risk factor.

Abstract
Associations between body mass index (BMI) and attempted (nonfatal) suicide have recently been reported. However, the few existing studies are relatively small in scale, the majority cross-sectional, and results contradictory. The authors have explored BMI-attempted suicide associations in a large cohort of 1,133,019 Swedish men born between 1950 and 1976, with BMI measured in early adulthood. During a mean follow-up of 23.9 years, a total of 18,277 (1.6%) men had at least 1 hospital admission for attempted suicide. After adjustment for confounding factors, there was a stepwise, linear decrease in attempted suicide with increasing BMI across the full BMI range (per standard deviation increase in BMI, hazard ratio = 0.93, 95% confidence interval: 0.91, 0.94). Analyses excluding men with depression at baseline were essentially identical to those based on the complete cohort. In men free from depression at baseline, controlling for subsequent depression slightly attenuated the raised risk of attempted suicide, particularly in lower weight men. This study suggests that lower weight men have an increased risk of attempted suicide and that associations may extend into the "normal" BMI range.

Abstract
Associations between suicide, violent behaviour and both hypocholesterolaemia and low 5-hydroxyindolacetic acid (5-HIAA) in the cerebrospinal fluid (CSF) have been suggested. The relationships between lipids, the serotonergic system, suicidal and aggressive behaviors are complex. We explored relationships between serum cholesterol, CSF 5-HIAA, the planning subscale of suicide intent and violence of attempted suicide method in 13 medication-free male suicide attempters and eight healthy volunteers. Serum high-density lipoprotein cholesterol (HDL-C) levels were significantly lower in suicide attempters than in controls. HDL-C showed a significant positive correlation with the planning subscale of suicide intent in non-violent suicide attempters. A positive association was observed between CSF 5-HIAA and serum cholesterol in suicides. The role of cholesterol may be different in planned non-violent suicide attempts compared with violent suicide attempts.

Abstract
To verify the hypothesis that suicide attempts are associated with lower serum cholesterol and triglyceride levels of patients with mood disorders, 26 patients with mood disorders (bipolar disorder and major depressive disorder) were admitted after a medically serious suicide attempt to the emergency department and then hospitalized in the psychiatric unit of the Sant'Andrea Hospital (Rome, Italy). Controls were 87 patients who had not made a recent suicide attempt. Attempters and nonattempters did not differ in the levels of serum cholesterol or triglycerides. Indeed, attempters had nonsignificantly higher serum levels of cholesterol and lower serum levels of triglycerides. The use of biologic indicators such as levels of serum cholesterol and triglycerides in the prediction of suicide risk in mood disorders was not fully supported from this small sample.

Abstract
Understanding factors associated with death wishes and suicidal ideation (SID) may help to improve identification of subjects at risk in the general population. We assessed SID in a population-based sample of 3079 subjects, 35 to 84 years and examined multiple sex- and age-adjusted affective and bio-behavioral covariates. Anxiety and a high level of somatic complaints, particularly dyspnea, contributed to the SID risk. However, the clinical picture of subjects suffering from SID was dominated by a 6-fold adjusted increased risk of a depressive syndrome followed by impaired self perceived health (3-fold risk) in both sexes. In men, unemployment status and living alone also increased SID risk substantially. These factors open new insights for our understanding of the multifaceted etiology of suicide risks offering new strategies for early detection of subjects at risk.

Abstract
Higher BMI has been associated with a lower risk of suicide in large prospective studies, but the mechanisms for this link require elucidation. In the 2002 and 2004 iterations of the Behavioral Risk Factor Surveillance System (BRFSS), a large, population-based telephone survey of US adults conducted by the Centers for Disease Control and Prevention, participants reported their height, weight, and several potential risk factors for suicide, including alcohol use, mental health, marital status, firearm ownership, and risk-taking behaviors. We assessed whether BMI was associated with these risk factors among 224,247 eligible respondents in 2002 and 275,194 in 2004 after sample-weighted adjustment for age, race, region, smoking, and education. Alcohol-related risk factors tended to be lower with heavier BMI among women, while firearm-related risk factors tended to be higher with heavier BMI among men. Heavier BMI also tended to be associated with unmarried status and poor mental health, especially among women, and with infrequent seat belt use in men and women. No potential risk factors were consistently inversely associated with BMI in both sexes and years. In summary, in these samples of the US population, conventional risk factors for suicide were inconsistently associated with BMI, making them unlikely mediators for the observed relationship of BMI with lower risk of suicide. In some cases, risk factors were actually greater with heavier BMI. Further study of the relationship of BMI and suicide may yield novel modifiable risk factors that could cause or prevent this important cause of death.

Abstract
Patient with mental illnesses such as schizophrenia and bipolar disorder have an increased prevalence of metabolic syndrome (MetS) and its components compared to general population. Among psychiatric disorders, bipolar disorder ranks highest in suicidality with a relative risk ratio of completed suicide of about 25 compared to the general population. Regarding the biological hypotheses of suicidality, low blood cholesterol level has been extensively explored, although results are still conflicting. The aim of this study was to investigate whether there were differences in the serum cholesterol levels in hospitalized bipolar disorder men patients with history of suicide attempts (N=20) and without suicide attempts (N=20). Additionally, we investigated if there were differences in the prevalence of MetS according to NCEP ATP-III criteria in these two groups of patients. Results of the study indicated significantly lower serum cholesterol levels (p=0.013) and triglyceride levels (p=0.047), in the bipolar disorder men with suicide attempts in comparison to bipolar disorder men without suicide attempts. The overall prevalence of MetS was 11/40 (27.5%). On this particular sample it was higher in the non-attempters 8/20 (40.0%) than in attempters 3/20 (15.0%) bipolar men group, but without statistical significance. Lower concentrations of serum cholesterol might be useful biological markers of suicidality in men with bipolar disorder.

Abstract
Among risk factors for suicide, suicidal ideation (SID) is of paramount importance. This study sought to determine sex- and age-related SID point prevalence rates in the general population. A population-based survey of 3154 subjects, 35 to 84 years, conducted in 2004/05 in southern Germany, identified 170 subjects (5.4%; 95% CI 4.6-6.2) suffering from SID within the last 14 days. Age-adjusted short-term period prevalence in women (6.0%, 95% CI 4.9.-7.2) was higher than in men (4.0%, 95% CI 3.1-5.1). Among 10-year age groups, sex-related differences were only significant in middle-aged subjects (55-64 years). Prevalence increased significantly with age, leading to a prevalence of >10% in the oldest age group (75-84 years). The population-based approach demonstrates a substantial proportion of subjects suffering from SID, particularly in older age groups.

Abstract
Low cholesterol levels have commonly been associated with various suicide measures. We sought to examine suicide attempts in a prospective sample of depressed patients that on prior analysis demonstrated an association between low cholesterol and subsequent suicide completions. Seventy-four inpatients with Research Diagnostic Criteria unipolar major depression, bipolar depression or schizoaffective depression entered a prospective follow-up study from 1978 to 1981. Kaplan-Meier survival analysis and Cox regression were utilized to elucidate the relationship between cholesterol levels and subsequent severe suicide attempts as well as all suicide attempts regardless of severity. Attempts preceding index hospitalization and other lifetime attempts were evaluated cross-sectionally. Low serum cholesterol levels did not predict subsequent suicide attempts. Contrary to our hypothesis, the high cholesterol group was associated with increased risk of suicide attempts on survival analysis in those less than median age. Nonetheless, in cross-sectional analysis, the low cholesterol group had more suicide attempts preceding index hospitalization and more remote lifetime attempts. The results from this prospective dataset do not support an association between low cholesterol and subsequent suicide attempts despite replicating the retrospective findings of previous case-control and cross-sectional studies.

Abstract
Findings from animal and human studies suggest an association between low cholesterol levels and suicidal behaviors. The purpose of this case-control study was to test whether cholesterol levels in suicide attempters are lower than in controls without suicide attempt history matched by gender, age, and body mass index (BMI). Suicide attempters (n=177: 68 men and 109 women) and controls (177 blood donors) were assessed. Serum cholesterol levels were significantly lower in suicide attempters than in controls. After gender stratification, the difference remained significant in men, but not in women.
