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. 相似文献

Higher rates of attempted suicide have been documented among people who identify themselves as gay, lesbian, and bisexual (LGB) compared with heterosexuals. This study sought to ascertain the association between childhood abuse and neglect and attempted suicide, comparing LGBs and heterosexuals. Childhood sexual abuse among men and childhood sexual and physical abuse among women were found to mediate the association between LGB identity and attempted suicide. The experience of childhood abuse likely plays a significant role in the relationship between LGB identity and attempted suicide, but other factors such as experience of discrimination are also important. 相似文献

Suicide is the second leading cause of death for traditional‐age college students, and the interpersonal theory of suicide (ITS; Joiner, 2005) provides a cogent framework for predicting which students may be at highest risk. However, little is known about how constructs of ITS operate in cross‐cultural contexts. Findings, based on a sample of international and domestic undergraduate students (N = 254), indicated that the ITS construct of perceived burdensomeness was positively associated with suicidal ideation (SI) for both groups. However, campus belongingness emerged as connected with SI for international students, whereas family belongingness emerged as connected with SI for domestic students. 相似文献

In this ecological study, we investigated whether help‐seeking related to stigma, intentions, and attitudes toward suicide are associated with the suicide rates of 20 regions within the Netherlands and Belgium. Significant associations were found between regional suicide rates and the intention to seek informal help (β = ?1.47, p = .001), self‐stigma (β = 1.33, p = .038), and shame (β = .71, p = .030). The association between self‐stigma and suicide rate was mediated by intentions to seek informal help. These results suggest that to promote suicide prevention at the level of the regional population, stigma, shame, and intentions to seek help should be targeted in the public domain. 相似文献

Although posttraumatic stress disorder (PTSD) and other psychiatric symptoms are well‐established risk factors for suicidal ideation among returning veterans, less attention has been paid to whether the stress of reintegrating into civilian society contributes to suicidal ideation. Utilizing a sample of 232 returning veterans (95% male, mean age = 33.63 years) seeking PTSD treatment, this study tested whether reintegration difficulties contribute to suicidal ideation over and above the influence of PTSD symptoms, depression symptoms, and potential substance misuse. Logistic regressions indicated that reintegration stress had a unique effect on suicidal ideation over and above PTSD and depression symptoms. Reintegration stress interacted with substance misuse to predict suicidal ideation, such that the effect of reintegration stress on suicidal ideation was much larger for those with potential substance misuse. Exploratory analyses also examined which types of reintegration difficulties were associated with suicidal ideation, and found that difficulty maintaining military friendships, difficulty getting along with relatives, difficulty feeling like you belong in civilian society, and difficulty finding meaning/purpose in life were all significantly associated with suicidal ideation, beyond the effects of psychiatric symptoms and potential substance misuse. Findings highlight the importance of addressing reintegration stress for the prevention of suicide among returning veterans. Implications for treatment are discussed. 相似文献

Military personnel can be exposed to a wide range of sexual trauma while deployed, including sexual harassment and sexual assault. We examined whether different types of sexual trauma during deployment associated with recent suicidal ideation among previously deployed OEF/OIF/OND veterans admitted to trauma‐focused treatment (n = 199). More severe forms of sexual trauma (e.g., sexual assault) were significantly and positively associated with suicidal ideation. In contrast, sexual trauma involving verbal remarks (e.g., sexual harassment) was not associated with suicidal ideation. Our findings suggest that sexual harassment and sexual assault during deployment may be differentially associated with suicidal ideation. 相似文献

The relationship between shyness and the interpretations of the facial expressions of others was examined in a sample of 123 children aged 12 to 14 years. Participants viewed faces displaying happiness, fear, anger, disgust, sadness, surprise, as well as a neutral expression, presented on a computer screen. The children identified each expression by pressing a button on an external keyboard. For each expression, children also rated (a) the degree to which they felt the child displaying the expression would like them, (b) the probability that someone at school would look at them with that expression, and (c) their own emotional reaction to interacting with a child displaying the expression. Participants also completed the Children's Shyness Questionnaire and the Children's Rejection Sensitivity Questionnaire. We hypothesized that shyness in children would be related to negatively biased interpretations of facial expressions. Although the accuracy with which the children could identify the facial expressions was not related to their degree of shyness, negative biases were found in their interpretations of the meanings of the expressions. Furthermore, rejection sensitivity significantly mediated many of these biased interpretations. These findings may have implications for interventions for children experiencing shyness and social anxiety, especially social‐skills training approaches.
