Front Psychiatry 2023; 14:1212579. [PMID: 37484676 PMCID: PMC10360170 DOI: 10.3389/fpsyt.2023.1212579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 06/21/2023] [Indexed: 07/25/2023] Open
Abstract
Introduction This study aims to explore the risk factors associated with suicidal behavior and establish predictive models in female patients with mood disorders, specifically using a nomogram of the least absolute shrinkage and selection operator (LASSO) regression. Methods A cross-sectional survey was conducted among 396 female individuals diagnosed with mood disorders (F30-F39) according to the International Classification of Diseases and Related Health Problems 10th Revision (ICD-10). The study utilized the Chi-Squared Test, t-test, and the Wilcoxon Rank-Sum Test to assess differences in demographic information and clinical characteristics between the two groups. Logistic LASSO Regression Analyses were utilized to identify the risk factors associated with suicidal behavior. A nomogram was constructed to develop a prediction model. The accuracy of the prediction model was evaluated using a Receiver Operating Characteristic (ROC) curve. Result The LASSO regression analysis showed that psychotic symptoms at first-episode (β = 0.27), social dysfunction (β = 1.82), and somatic disease (β = 1.03) increased the risk of suicidal behavior. Conversely, BMI (β = -0.03), age of onset (β = -0.02), polarity at onset (β = -1.21), and number of hospitalizations (β = -0.18) decreased the risk of suicidal behavior. The area under ROC curve (AUC) of the nomogram predicting SB was 0.778 (95%CI: 0.730-0.827, p < 0.001). Conclusion The nomogram based on demographic and clinical characteristics can predict suicidal behavior risk in Chinese female patients with mood disorders.

Abstract
BACKGROUND Suicide is a leading cause of death in South Korea (hereafter 'Korea'), and there is evidence that body weight and perceived weight affecting suicide have a significant effect on suicidal behavior in adolescence. This study investigated the association between body mass index (BMI), perceived weight, and suicide attempts in adolescents. METHODS We included nationally representative data for a total of 106,320 students in our final analysis. We calculated and stratified BMI (underweight, normal weight, overweight) to determine the correlation between BMI and suicide attempts. We stratified the participants into three groups (perceived as underweight, normal weight, and overweight) for subjective body weight perception to analyze the relationship between subjective body weight perception and suicide attempts. We further analyzed the combination of BMI and subjective body weight perception to determine the relationship between suicide attempts and distorted subjective weight perception. RESULTS Compared with perceiving oneself as having a normal weight, the odds ratios (ORs) for suicide attempts were significantly increased in the group perceiving themselves as overweight. In addition, those who perceived themselves as overweight but were underweight according to their BMI were at significantly increased risk of suicide attempts relative to those who perceived themselves as about the right weight. CONCLUSIONS There was a significant association with suicide attempts in the underweight and perceived overweight group. This shows the importance of combining BMI and perceived weight when examining the relationship between weight and suicide attempts in adolescents.

Abstract
Background The high rates of obesity and suicide have become serious public health problems worldwide, especially in children and adolescents with major depressive disorder (MDD). This research aimed to explore the rates of underweight, overweight or obesity, suicidal ideation and attempted suicide in hospitalized children and adolescents with MDD. Then, we analyzed the correlation between underweight or obesity and suicidal ideation and attempted suicide, and finally obtained the independent influencing factors of underweight or obesity. Methods A total of 757 subjects in the Third People's Hospital of Fuyang from January 2020 to December 2021 were enrolled in this study. According to the underweight, overweight and obesity screening table for school-age children and adolescents published and implemented by the health industry standard of China, all subjects were divided into different body mass index (BMI) categories. We measured fasting blood glucose (FBG) and lipid levels in all subjects and assessed suicidal ideation, attempted suicide, and the severity of depressive symptoms. The socio-demographic and clinical data were collected and analyzed by SPSS 22.0. Results The rates of underweight, overweight, obesity, suicidal ideation and attempted suicide were 8.2% (62/757), 15.5% (117/757), 10.4% (79/757), 17.2% (130/757), and 9.9% (75/757), respectively. Correlation analysis indicated that BMIs level was positively correlated with age, age of first hospitalization, total duration of disease, number of hospitalizations, FBG, TG (triglyceride), TC (total cholesterol), LDL (low density lipoprotein), and negatively correlated with HDL (high density lipoprotein). Binary logistic regression analysis showed that male and high level of HDL were risk factors for MDD inpatients with underweight, while high level of TG was a protective factor. Meanwhile, higher levels of FBG, TG and CGI-S were risk factors and suicidal ideation and high dose of antidepressant drugs were protective factors for obesity in children and adolescents with MDD. Conclusion The prevalence of underweight, obesity, suicidal ideation and attempted suicide were high in children and adolescents with MDD, and severe depressive symptoms are independent risk factors for obesity, while suicidal ideation and high dose of antidepressants may be protective factors for obesity.

Abstract
The prevalence of both obesity and suicide ideation has risen in the last several decades among young adults in the United States (U.S.). Obesity is highly stigmatized in the U.S. and leads to discrimination and societal rejection, which suggests that obesity may increase the risk of suicide ideation. However, no U.S. population-representative studies to date have investigated the relationship between body weight and suicide ideation among young adults. We make this contribution by analyzing data from Wave III of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Our results indicate obesity is not related to suicide ideation among young men or young women and overweight young men have lower odds of suicide ideation than normal weight young men. We speculate that these findings may be attributable to the very high U.S. overweight and obesity prevalence, which has made obesity more common despite stigmatization. First nationally representative study of young adults' weight and suicide ideation. Obesity is not associated with suicide ideation among U.S. young men and women. Overweight is associated with a lower risk of suicide ideation among young men.

Abstract
BACKGROUND/OBJECTIVES Numerous school-based weight control programs have been initiated for weight loss among adolescents. However, the relationship between these programs and inappropriate weight control efforts, dietary habits and behavior of students, have not been investigated sufficiently. This study was undertaken to investigate the association between body mass index (BMI) of adolescents, and their health status and inappropriate weight-control efforts. We further examined the relationship between attendance to school-based weight-control programs and attempting inappropriate weight-control efforts, dietary habits, and behavior. SUBJECTS/METHODS A survey of 1,742 students was conducted in Korea. Logistic regression was used to assess differences in the health status (grouped by BMI and improper weight control) and dietary habits, based on attendance to the weight-control programs. RESULTS Obese students were significantly more dissatisfied with physical, mental and spiritual health. Students who attended weight-control programs were likely to be underweight (P < 0.001), whereas those who did not attend weight-control programs were likely to attempt weight control improperly (P < 0.001). Students who participated in the program also had relatively healthy dietary habits (P < 0.001-0.027), and students who did not attend had comparatively unhealthy dietary habits (P < 0.001-0.008). Students who attended weight-control programs were likely to be underweight (P < 0.001) with relatively healthy dietary habits (P < 0.001-0.027), whereas students who did not attend the programs were likely to attempt weight control improperly (P < 0.001) and had comparatively unhealthy dietary habits (P < 0.001-0.008). CONCLUSIONS Attending school-based weight-control programs was significantly associated with not attempting inappropriate weight-control efforts, as well as following healthy dietary habits. Our data indicates that offering school-based weight-control programs is valuable to student health, and is anticipated to reducing the public health burden.

Abstract
RATIONALE Suicides by men outnumber those by women in every country of the world. To date, there has not been a comprehensive systematic review of risk factors for suicidal behaviour in men to better understand the excess deaths by suicide in men. OBJECTIVE The present systematic review seeks to determine the nature and extent of the risk factors to predict suicidal behaviour in men over time. METHODS A range of databases (CINAHL, PsycINFO, Web of Science Core Collection, Pubmed, Embase, and Psychology and Behavioural Sciences Collection) were searched from inception to January 2020 for eligible articles. The findings were collated through a narrative synthesis of the evidence. RESULTS An initial 601 studies were identified. Following the inclusion and exclusion criteria, there were 105 eligible studies (62 prospective and 43 retrospective) identified. Overall, the risk factors with the strongest evidence predicting suicidal behaviour in men were alcohol and/or drug use/dependence; being unmarried, single, divorced, or widowed; and having a diagnosis of depression. In the prospective studies, the most consistent evidence was for sociodemographic factors (19 risk factors), mental health/psychiatric illness (16 risk factors), physical health/illness (13 risk factors), and negative life events/trauma (11 risk factors). There were a small number of psychological factors (6 factors) and characteristics of suicidal behaviour (3 factors) identified. The findings from the retrospective studies provided further evidence for the risk factors identified in the prospective studies. CONCLUSIONS This systematic review has highlighted the wide range of risk factors for suicidal behaviour in men, in this review alone 68 different risk factors were identified. Many factors can interact and change in relevance throughout an individual's life. This review has identified extensive gaps in our knowledge as well as suggestions for future research.

Abstract
BACKGROUND Obesity, depressive disorders and antidepressant drugs are associated with increased mortality, cardiovascular disease, diabetes, fractures and falls. We explored outcomes associated with the most commonly prescribed antidepressants in overweight or obese people with depression. METHODS AND FINDINGS We identified a cohort of overweight or obese adults (≥18 years) in primary care from the UK Clinical Practice Research Datalink, linked with hospital and mortality data, between 1 January 2000 and 31 December 2016 who developed incident depression to January 2019. Cox proportional hazards models and 99% confidence intervals were used to estimate hazard ratios (HR) for mortality, cardiovascular disease, diabetes, and falls/fractures associated with exposure to selective serotonin reuptake inhibitors (SSRIs), tricyclic (TCA)/other, combination antidepressants, citalopram, fluoxetine, sertraline, amitriptyline and mirtazapine, adjusting for potential confounding variables. In 519,513 adults, 32,350 (9.2 per 1,000 years) displayed incident depression and 21,436 (66.3%) were prescribed ≥1 antidepressant. Compared with no antidepressants, all antidepressant classes were associated with increased relative risks of cardiovascular disorders [SSRI HR: 1.32 (1.14-1.53), TCA/Other HR: 1.26 (1.01-1.58)], and diabetes (any type) [SSRI HR: 1.28 (1.10-1.49), TCA/Other: 1.52 (1.19-1.94)]. All commonly prescribed antidepressants except citalopram were associated with increased mortality compared with no antidepressants. However, prescription ≥1 year of ≥40mg citalopram was associated with increased mortality and falls/fractures and ≥1 year 100mg sertraline with increased falls/fractures. CONCLUSIONS In overweight/obese people with depression, antidepressants may be overall and differentially associated with increased risks of some adverse outcomes. Further research is required to exclude indication bias and residual confounding.

Abstract
BACKGROUND Suicidal outcomes, including ideation, attempt, and completed suicide, are an important drug safety issue, though few epidemiological studies address the accuracy of suicidal outcome ascertainment. Our primary objective was to evaluate validated methods for suicidal outcome classification in electronic health care database studies. METHODS We performed a systematic review of PubMed and EMBASE to identify studies that validated methods for suicidal outcome classification published 1 January 1990 to 15 March 2016. Abstracts and full texts were screened by two reviewers using prespecified criteria. Sensitivity, specificity, and predictive value for suicidal outcomes were extracted by two reviewers. Methods followed PRISMA-P guidelines, PROSPERO Protocol: 2016: CRD42016042794. RESULTS We identified 2202 citations, of which 34 validated the accuracy of measuring suicidal outcomes using International Classification of Diseases (ICD) codes or algorithms, chart review or vital records. ICD E-codes (E950-9) for suicide attempt had 2-19% sensitivity, and 83-100% positive predictive value (PPV). ICD algorithms that included events with 'uncertain' intent had 4-70% PPV. The three best-performing algorithms had 74-92% PPV, with improved sensitivity compared with E-codes. Read code algorithms had 14-68% sensitivity and 0-56% PPV. Studies estimated 19-80% sensitivity for chart review, and 41-97% sensitivity and 100% PPV for vital records. CONCLUSIONS Pharmacoepidemiological studies measuring suicidal outcomes often use methodologies with poor sensitivity or predictive value or both, which may result in underestimation of associations between drugs and suicidal behaviour. Studies should validate outcomes or use a previously validated algorithm with high PPV and acceptable sensitivity in an appropriate population and data source.

Abstract
Severe obesity has many psychiatric consequences that can be influenced by bariatric surgery. The goal of this article is to review these challenges, including the mental health status of patients with severe obesity, the evaluation of surgical candidates, and the early and late effects of the operations, and to offer some recommendations to manage these challenges. The failure of the insurance-mandated preoperative psychosocial evaluation is also discussed.

Abstract
BACKGROUND There is conflicting evidence about the relationship between body mass index (BMI) and suicide death. This study aimed to characterize and compare suicide deaths by weight using BMI weight categories. METHODS We examined suicide deaths in adults in the city of Toronto (2009-2015); grouped them by BMI categories (underweight, normal weight, overweight, and obese) and compared groups based on demographics, clinical variables and method of suicide death. RESULTS Suicide decedents' (n = 1429) mean age was 48.6 years (SD = 17.4) and mean BMI was 25.5 (SD = 5.4). Underweight decedents were more likely to be female and to have cancer while obese decedents were more likely to have diabetes. Underweight decedents were more likely to have an identified history of any medical condition. Obese and overweight decedents were significantly more likely to have an identified history of any psychiatric condition. Non-violent methods (e.g., self-poisoning) were used at a higher proportion by people with obesity and by people who were underweight. LIMITATIONS Psychological autopsies were not available and it was not possible to assess for change in or stability of BMI over time. CONCLUSIONS These findings add to our understanding of the relationship between suicide and weight. A higher prevalence of females as well as those with a history of cancer and any medical condition in underweight decedents was noteworthy and of potential clinical significance.

Psychol Med 2019; 49:2279-2286.

Abstract
BACKGROUND High body mass index (BMI) has been associated with lower risks of suicidal behaviour and being underweight with increased risks. However, evidence is inconsistent and sparse, particularly for women. We aim to study this relationship in a large cohort of UK women. METHODS In total 1.2 million women, mean age 56 (s.d. 5) years, without prior suicide attempts or other major illness, recruited in 1996-2001 were followed by record linkage to national hospital admission and death databases. Cox regression yielded relative risks (RRs) and 95% confidence intervals (CIs) for attempted suicide and suicide by BMI, adjusted for baseline lifestyle factors and self-reported treatment for depression or anxiety. RESULTS After 16 (s.d. 3) years of follow-up, 4930 women attempted suicide and 642 died by suicide. The small proportion (4%) with BMI <20 kg/m2 were at clearly greater risk of attempted suicide (RR = 1.38, 95% CI 1.23-1.56) and suicide (RR = 2.10, 1.59-2.78) than women of BMI 20-24.9 kg/m2; p < 0.0001 for both comparisons. Small body size at 10 and 20 years old was also associated with increased risks. Half the cohort had BMIs >25 kg/m2 and, while risks were somewhat lower than for BMI 20-24.9 kg/m2 (attempted suicide RR = 0.91, 0.86-0.96; p = 0.001; suicide RR = 0.79, 0.67-0.93; p = 0.006), the reductions in risk were not strongly related to level of BMI. CONCLUSIONS Being underweight is associated with a definite increase in the risk of suicidal behaviour, particularly death by suicide. Residual confounding cannot be excluded for the small and inconsistent decreased risk of suicidal behaviour associated with being overweight or obese.

Family-based analyses reveal novel genetic overlap between cytokine interleukin-8 and risk for suicide attempt. Brain Behav Immun 2019; 80:292-299. [PMID: 30953777 PMCID: PMC7168352 DOI: 10.1016/j.bbi.2019.04.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 02/25/2019] [Accepted: 04/02/2019] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Suicide is major public health concern. It is imperative to find robust biomarkers so that at-risk individuals can be identified in a timely and reliable manner. Previous work suggests mechanistic links between increased cytokines and risk for suicide, but questions remain regarding the etiology of this association, as well as the roles of sex and BMI. METHODS Analyses were conducted using a randomly-ascertained extended-pedigree sample of 1882 Mexican-American individuals (60% female, mean age = 42.04, range = 18-97). Genetic correlations were calculated using a variance components approach between the cytokines TNF-α, IL-6 and IL-8, and Lifetime Suicide Attempt and Current Suicidal Ideation. The potentially confounding effects of sex and BMI were considered. RESULTS 159 individuals endorse a Lifetime Suicide Attempt. IL-8 and IL-6 shared significant genetic overlap with risk for suicide attempt (ρg = 0.49, pFDR = 7.67 × 10-03; ρg = 0.53, pFDR = 0.01), but for IL-6 this was attenuated when BMI was included as a covariate (ρg = 0.37, se = 0.23, pFDR = 0.12). Suicide attempts were significantly more common in females (pFDR = 0.01) and the genetic overlap between IL-8 and risk for suicide attempt was significant in females (ρg = 0.56, pFDR = 0.01), but not in males (ρg = 0.44, pFDR = 0.30). DISCUSSION These results demonstrate that: IL-8 shares genetic influences with risk for suicide attempt; females drove this effect; and BMI should be considered when assessing the association between IL-6 and suicide. This finding represents a significant advancement in knowledge by demonstrating that cytokine alterations are not simply a secondary manifestation of suicidal behavior, but rather, the pathophysiology of suicide attempts is, at least partly, underpinned by the same biological mechanisms responsible for regulating inflammatory response.

Abstract
BACKGROUND Metabolic disturbances have been correlated with suicidality, but little is known about the association between suicide risk and metabolic disturbances among individuals with depression. This study was to evaluate the prevalence and clinical correlations, especially cardio-metabolic associated factors of recent suicide attempts in Chinese patients with major depressive disorder (MDD). METHODS A total of 288 MDD inpatients were recruited. Their clinical and demographic data together with plasma glucose, lipid and thyroid function parameters were collected. Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS) and Eysenck Personality Questionnaire (EPQ) were rated for most of the patients. RESULTS Of these MDD inpatients, 20.14% had attempted suicide during the past 1 month. Compared to those who had not attempted suicide, the suicide attempters had a significantly longer duration of illness, lower low-density lipoprotein (LDL) cholesterol, lower total cholesterol, and more psychotic symptoms. However, all these significant results did not survive after the bonferroni correction (all p > 0.05). A logistic regression analysis indicated that suicide attempts were associated with the lower total cholesterol and more psychotic symptoms. CONCLUSIONS Our findings support the hypothesis of the association of low plasma cholesterol level and recent suicidal attempts in patients with MDD.

Abstract
Gender-based differences in body image dissatisfaction are not conclusive. Women's body experiences and their impact on sexual satisfaction may advance knowledge on how heterosexual, bisexual, and lesbian women internalize heterosexist values. In this study, we quantitatively examined the degree of body image and sexual dissatisfaction experienced by heterosexual, bisexual, and lesbian women, to determine whether body dissatisfaction can predict sexual dissatisfaction. Three hundred and fifty-four women completed an online survey measuring body and sexual dissatisfaction. No sexual orientation-based differences were observed in body or sexual dissatisfaction; however, body concerns were found to have less influence on sexual dissatisfaction in lesbian women compared to heterosexual and bisexual women. Standards of beauty remain constant among all women, yet removing themselves from the male gaze may be interpreted as a protective factor which shields women from expressing concern about their appearance during sexual activity.

Abstract
OBJECTIVE Associations between suicidality and lipid dysregulation are documented in mental illness, but the potential role of leptin remains unclear. We examined the association between leptin and suicidal behaviour in schizophrenia, together with the influence of other clinical and biological indices. METHOD We recruited a sample of 270 participants with schizophrenia spectrum diagnoses. Blood samples were analysed for leptin, while symptom severity was assessed by Positive and Negative Syndrome Scale (PANSS) and Inventory of Depressive Symptomatology (IDS-C). Patients' history of suicidal behaviour was categorized into three subgroups based on IDS-C suicide subscale: No suicidal behaviour, mild/moderate suicidal behaviour and severe suicidal behaviour with/without attempts. RESULTS Mild/moderate suicidal behaviour was present in 17.4% and severe suicidal behaviour in 34.8%. Both groups were significantly associated with female gender (OR = 6.0, P = 0.004; OR = 5.9, P = 0.001), lower leptin levels (OR = 0.4, P = 0.008; OR = 0.5, P = 0.008) and more severe depression (OR = 1.2, P < 0.001; OR = 1.1, P < 0.001) respectively. Smoking (OR = 2.6, P = 0.004), younger age of onset (OR = 0.9, P = 0.003) and less use of leptin-increasing medications (OR = 0.5, P = 0.031) were associated with severe/attempts group, while higher C-reactive protein CRP (OR = 1.3, P = 0.008) was associated with mild/moderate group. CONCLUSION Lower leptin levels were associated with higher severity of suicidal behaviour in schizophrenia.

Chinese Sexual Minority Male Adolescents' Suicidality and Body Mass Index. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15112558.

Abstract
Excess weight status may increase the risk of suicidality among sexual minority females, but few studies have examined this suicidality disparity in sexual minority males. This study examined the association between sexual minority status and suicide attempts in Chinese male adolescents and tested whether body mass index (BMI) had a moderating effect on that association. Data were collected from 7th to 12th graders from seven randomly selected provinces of China in the 2015 School-Based Chinese Adolescents Health Survey. In total, 72,409 male students completed the questionnaires regarding sexual attraction, self-reported weight and height, and suicide attempts. After adjustment for covariates, sexual minority status was associated with suicide attempts among male students (AOR = 1.74, 95% CI = 1.57–1.93). Stratification analyses showed that BMI category moderated this association; compared with the results before stratification analyses, sexual minority males who were obese had increased risk of suicide attempts (AOR = 2.15, 95% CI = 1.09–4.24), sexual minority males who were overweight had reduced odds of suicide attempts (AOR = 1.40, 95% CI = 1.01–1.92), and no significant association change was found in sexual minority males who were underweight (AOR = 1.82, 95% CI = 1.43–2.33). Our study indicated that BMI moderated the risk of suicide attempts in sexual minority males. Suicide prevention targeting sexual minority males should be focused on weight status disparity and the creation of a positive climate to reduce minority stressors due to body image.

Abstract
BACKGROUND While restrictive and compensatory eating disorders (e.g. anorexia and bulimia) are associated with elevated risk of suicide, less is known about binge eating disorder (BED). There is suggestive evidence of a U-shaped relationship between body mass index (BMI) and completed suicide, but fewer studies on suicidal ideation or attempts. This study examined the association between BED, BMI, and suicidality, and assessed whether these relationships varied by gender. METHODS Data come from the Collaborative Psychiatric Epidemiologic Surveys (N = 14,497). Binge episodes and BED were assessed using the Composite International Diagnostic Inventory (CIDI). BMI was calculated from self-reported height and weight. Suicidal ideation/attempts were assessed using the CIDI. Weighted logistic regression was used to assess the association between binging/BED, BMI and suicidality. Interaction terms were used to assess whether the relationship between BMI and suicidality was moderated by binging/BED, and whether the relationships between binging/BED and BMI differed by gender. RESULTS One-third of adults with BED had a history of suicidality, compared to 19% of those without. Both binging (OR: 1.95, 95% CI: 1.50-2.53) and BED (OR: 2.01, 95% CI: 1.41-2.86) were associated with suicidality in fully-adjusted models. BMI was associated with suicidality in a curvilinear manner, and this relationship was exacerbated by binging/BED (ORBinge eating x BMI: 1.04, 95% CI: 1.01-1.09, p < 0.05). The relationship between BMI and suicidality did not differ by gender (ORgender x BMI: 1.00, p < 0.770). However, the relationship between binge eating and suicidality was stronger for women relative to men (ORgender X binge: 1.87, p < 0.012). CONCLUSIONS Binge eating, even below the threshold for BED, is associated with suicidality. BMI is associated with suicidality in a curvilinear manner, and the BMI-suicidality relationship is potentiated by binge eating/BED. Findings support the thoughtful integration of psychiatric care into weight loss programs for adults with a history of binging behavior.

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 Previous studies investigating the risk of suicide in diabetes patients reported controversial findings. We did a systematic review and meta-analysis to comprehensively estimate the risk and incidence rate of suicide in diabetic patients. METHODS PubMed, EMBASE and PsycINFO were searched for eligible studies. Random-effects meta-analysis was used to calculate the relative risk (RR) and the incidence rate of suicide in diabetes patients. We also calculated the proportion of deaths attributable to suicide among diabetes patients. RESULTS 54 studies were finally included, including 28 studies on the suicide risk associated with diabetes, 47 studies on the incidence rate of suicide and 45 studies on the proportion of deaths attributable to suicide. Meta-analysis showed that diabetes could significantly increase the risk of suicide (RR = 1.56; 95% CI: 1.29-1.89; P < 0.001). Subgroup analysis showed that the RR of suicide associated with type 1 diabetes was 2.25 (95% CI: 1.50-3.38; P < 0.001). The pooled incidence rate of suicide in patients with diabetes was 2.35 per 10 000 person-years (95% CI: 1.51-3.64). The pooled proportions of long-term deaths attributable to suicide in type 1 diabetes patients and type 2 diabetes patients were 7.7% (95% CI: 6.0-9.8) and 1.3% (95% CI: 0.6-2.6), respectively. CONCLUSION This meta-analysis suggests that diabetes can significantly increase the risk of suicide. Suicide has an obvious contribution to mortality in diabetic patients, especially among type 1 diabetes patients. Effective strategies to decrease suicide risk and improve mental health outcomes in diabetes patients are needed.

Abstract
AIM Present study aimed at determining lipid profiles in acutely symptomatic drug-naïve/drug-free patients of schizophrenia, comparing them with healthy controls and exploring relationships between various lipid fractions, aggression, suicidality and impulsivity in this population. MATERIALS AND METHODS This was a cross-sectional hospital-based study, comparing patients with schizophrenia (M=46, F=14; mean age 32.40±6.6 years; 48 drug-free for 10.50±9.2 weeks) with 60 age-sex matched healthy controls. Upon recruitment, fasting venous blood samples of all subjects were analysed for total cholesterol, HDL, LDL, VLDL and TG levels, and patients were rated on PANSS for symptom severity, Modified Overt Aggression Scale for aggression, Impulsivity Rating Scale for impulsivity and Scale for Suicide Ideation for suicidality. RESULTS The socio-demographic characteristics of the patients were comparable to controls. In patients, total cholesterol, HDL and LDL levels were found to be significantly lower (p<0.01) than the control group. When explored further in patients, lower total cholesterol and LDL levels showed significant negative correlations with scores on impulsivity (p<0.01) and suicidality (p<0.05); and TG level showed a negative correlation with impulsivity (p<0.05). CONCLUSIONS This study adds to a growing literature on a complex relationship between lipid fractions and impulsivity, suicidality and aggression in schizophrenia; providing interesting insights into the biochemical basis of human behaviour and confirming these in a developing-world population. The implications are many, including a need to review judiciously the promotion of weight loss and cholesterol reduction programmes in constitutionally vulnerable population, at least during their acutely-symptomatic states.

Abstract
A nonlinear indirect effects framework was used to investigate potential interpersonal indirect effects (i.e., perceived burden and thwarted belonging) accounting for the nonlinear relationship between body mass index (BMI) and suicide ideation. Using a sample of 338 undergraduates, results revealed a significant quadratic effect of BMI on suicide ideation via perceived burden only, which became significant as BMI fell below 18.00 kg/m2 and above 28.00 kg/m2 . Our results provide novel information relevant for suicide risk screening in the context of weight- and health-related interventions and provide justification for future longitudinal trials assessing suicide risk across the BMI spectrum.

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
OBJECTIVES To examine the hypothesis that the relationship between obesity and the risk of suicidal behaviour would differ according to sex and age. SETTING Data from the 2007-2012 Korean National Health and Nutrition Examination Survey (KNHANES) were used. PARTICIPANTS 36 211 adults with body mass index (BMI) data were included and the mean age was 49.6 years. INDEPENDENT VARIABLE BMI. PRIMARY AND SECONDARY OUTCOME MEASURES Suicide ideation and attempts. DESIGN AND ANALYSIS A cross-sectional study was performed. Multiple logistic regressions after controlling for socioeconomic variables and concomitant diseases were applied to see the relationship between obesity level and suicidal ideation or attempt. RESULTS Women with severe obesity had the highest prevalence of suicide attempts and ideation, whereas among males, underweight men had the highest prevalence. After adjustment, obese men had a lower OR for suicide ideation (OR=0.87, 95% CI 0.76 to 1.00). Among women, the ORs of severely obese and underweight women were 1.27 (95% CI 1.06 to 1.52) and 1.24 (95% CI 1.06 to 1.45), respectively. When grouped by age category, the ORs for suicide ideation in severely obese women aged 18 to <30 years or attempts in severely obese women aged 30 to <50 years were 2.30 (95% CI 1.36 to 3.89) and 3.07 (95% CI 1.50 to 6.31), respectively. However, overweight and obese women aged more than 50 years exhibited significantly less ORs of suicide ideation, when compared with counterparts of normal weight. CONCLUSIONS The association between obesity and suicidal behaviour exhibited a different pattern by sex and age in South Korea. In particular, severely obese young women had a substantial risk of suicidal behaviour. Our study results highlighted the importance of obesity management in the prevention of suicide among young women, and may be helpful for the drafting of the health agenda in Asian countries with an obesity prevalence and culture similar to those in Korea.

Abstract
Overweight and obesity is associated with lower rates of suicide. However, little is known about the association with different suicide methods. We studied the association between groups of body mass index and suicide methods. We identified all medicolegal autopsy cases with a cause of death due to external causes in Sweden during 1999-2013 (N = 39,368) and included 11,715 suicides and 13,316 accidents or homicides as controls. We applied multinomial regression models adjusted for age, sex, year and season of death. Obesity was associated with suicidal intoxication, OR 1.15 [95% confidence interval (CI) 1.02, 1.30] and negatively associated with all other suicide methods studied. Underweight showed a negative association with suicidal drowning and there was an indication towards a negative association with hanging in men OR 0.81 (95% CI 0.65, 1.01). We conclude that body mass index (BMI) is associated with the choice of suicide method. This may be of importance in a public health perspective, e.g. potential for prevention of intoxications. In the practice of forensic medicine, the physician's level of suspicion may rise if the apparent suicidal method is less common for the individual characteristics of the deceased, such as BMI.

Abstract
The relationship between obesity and suicide risk is still unclear with controversial research results. The aim of this study is to investigate the relationship between obesity and suicide risk for men and women in a population-based study of young adults. This is a cross-sectional population-based study that identified young adults between 18 and 35 years of age. Suicide risk was investigated through the structured clinical interview Mini. Weight and height were assessed, and participants were classified as normal-weight body mass index (BMI < 30) or obese (BMI > 30). The prevalence of obesity was of 19.9% of the total sample (n = 1953). Obesity was more prevalent among women and participants between 27 and 35 years of age. Suicide risk was present in 13.0% of the sample and more prevalent among women. In our study we found an association between obesity and suicide risk for women, but not for men. Obesity was associated with a higher prevalence of suicide risk in women. Given the strength of the relationship between BMI and suicide, identifying the mechanisms associated with obesity, especially for women, can lead to new insights into the prevention of suicide risk.

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
BACKGROUND Being underweight has been related to health risks. However, little is known about the relationship between suicidal ideation and attempting to lose weight. This study was conducted to examine if there is an association between suicidal ideation and attempting to lose weight among underweight adults. METHODS A cross-sectional study of 1,122 underweight adults (range, 19 to 69 years) was conducted based on the Korea National Health and Nutrition Examination Survey, 2007-2012. We examined suicidal ideation, doctor-diagnosed depression, depressive mood, stress, physical activity, health-related behavior, comorbidity, and socioeconomic status by weight loss attempts. Logistic regression analysis was performed to examine the association between suicidal ideation and weight loss attempts. The following covariates were controlled for: age, sex, physical activity, alcohol problem, marital status, education, income, occupation, self-perception of body image, chronic disease, and body mass index. RESULTS There were 101 subjects in the weight loss attempt group and 1,021 in the non-attempt group. The attempt group had a higher risk of suicidal ideation (odds ratio [OR], 2.47; 95% confidence interval [CI], 1.35 to 4.53) and depressive symptoms (OR, 2.17; 95% CI, 1.19 to 3.98). After depressive symptoms were added to the covariates, the risk of suicidal ideation was also significant (OR 2.11, 95% CI: 1.03 to 4.35). The two groups did not significantly differ in doctor-diagnosed depression and stress. CONCLUSION Weight loss attempts were associated with suicidal ideation in underweight Korean adults.

Abstract
An association of higher body mass index (BMI) with lower risk of attempted and completed suicide has been reported. In contrast, increasing BMI has been found to be associated with depression and other risk factors for suicidal behavior. We aimed to investigate this possible paradox in a cohort comprising 49 000 Swedish men. BMI, mental health, lifestyle and socioeconomic measures were recorded at conscription in 1969-70, at ages 18-20. Information on attempted suicide 1973-2008 and completed suicide 1971-2008 was obtained from national records. Hazard ratios (HR) were estimated by Cox proportional hazard models. We found that each standard deviation (SD) increase in BMI was associated with a 12% lower risk of later suicide attempt (HR 0.88, 95% CI 0.83-0.94). Associations were somewhat weaker for completed suicide and did not reach conventional levels of statistical significance (HR 0.93, 95% CI 0.85-1.01). Adjustment for a wide range of possible confounding factors had little effect on the associations. Lower BMI at conscription was also associated with higher prevalence of psychiatric diagnoses, low emotional control and depressed mood. Our results confirm previous findings regarding the association of higher BMI with a reduced risk of suicide, extending them to show similar findings in relation to suicide attempts. The associations were little affected by adjustment for a range of possible confounding factors. However, we found no evidence that high BMI was associated with an increased risk of depression cross-sectionally or longitudinally.

Abstract
Background In contrast to obesity, information on the health risks of underweight is sparse. We examined the long-term association between underweight and mortality by considering factors possibly influencing this relationship. Methods We included 31,578 individuals aged 25–74 years, who participated in population based health studies between 1977 and 1993 and were followed-up for survival until 2008 by record linkage with the Swiss National Cohort (SNC). Body Mass Index (BMI) was calculated from measured (53% of study population) or self-reported height and weight. Underweight was defined as BMI < 18.5 kg/m2. Cox regression models were used to determine mortality Hazard Ratios (HR) of underweight vs. normal weight (BMI 18.5- < 25.0 kg/m2). Covariates were study, sex, smoking, healthy eating proxy, sports frequency, and educational level. Results Underweight individuals represented 3.0% of the total study population (n = 945), and were mostly women (89.9%). Compared to normal weight, underweight was associated with increased all-cause mortality (HR: 1.37; 95% CI: 1.14-1.65). Increased risk was apparent in both sexes, regardless of smoking status, and mainly driven by excess death from external causes (HR: 3.18; 1.96-5.17), but not cancer, cardiovascular or respiratory diseases. The HR were 1.16 (0.88-1.53) in studies with measured BMI and 1.59 (1.24-2.05) with self-reported BMI. Conclusions The increased risk of dying of underweight people was mainly due to an increased mortality risk from external causes. Using self-reported BMI may lead to an overestimation of mortality risk associated with underweight.
