The quadratic relationship between body mass index and suicide ideation: A nonlinear analysis of indirect effects.

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[…]

Body mass index, depression, and suicidality: The role of self-esteem in bariatric surgery candidates.

Highlights •3101 bariatric surgery candidates. •Self-esteem mediated the relationship between body mass index (BMI) and depression. •The relationship between BMI and suicidality was mediated by self-esteem. •The mediated pathways were stronger for males, than for females. •Findings may be used to optimize depression and interventions.[…]

Body mass index is an important predictor for suicide: Results from a systematic review and meta-analysis.

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.[…]

Involvement in Physical Activity and Risk for Nearly Lethal Suicide Attempts

This study compared reports of recent physical activity among those surviving a nearly lethal suicide attempt to reports from community controls. Analyses were conducted on data collected between November 1992-July 1995 for a study of nearly lethal suicide attempts among people aged 13-34 years. Logistic regression analyses were used to test the association between suicide[…]

Invited Commentary: Body Mass Index and Suicide – Untangling an Unlikely Association

A series of prospective studies have found body mass index to be inversely associated with risk of suicide. In the progression from disturbed mental health to suicide ideation to attempted suicide & suicide, augmented by impulsivity & access to highly lethal means, there are several potential steps at which body mass index has been hypothesized[…]

Batty et al. Respond to “BMI and Suicide – Untangling an Unlikely Association”

In this commentary, Batty & his colleagues respond to Mukamal & Miller’s comments on their study of body mass index & suicide. Mukamal & Miller discussed the issue of confounding factors & it is this issue that Batty et al focus on & how it might be circumvented. (7 refs.) JA Contact us for a[…]

BMI and Risk Factors for Suicide: why is BMI Inversely Related to Suicide?

In 2002 & 2004 telephone surveys of American adults, participants reported their height, weight, & several potential risk factors for suicide. This study assessed whether body mass index was associated with the risk factors among 224,247 respondents in 2002 & 275,194 in 2004 after sample-weighted adjustment for age, ethnicity, region, smoking, & education. Alcohol-related risk[…]

BMI and Rates of Suicide in the United States: an Ecological Analysis

The authors ascertained recent population-based, state-level data on rates of obesity, completed suicide by method, firearm ownership, smoking, major depression, income, education, white ethnicity, & nonmetropolitan residence & determined the adjusted population-weighted correlations of statewide obesity rates with measures of completed & attempted suicide. Statewide prevalence of obesity was strongly inversely correlated with age-adjusted suicide[…]

Suicidal Behavior in Adolescents: Relationship to Weight Status, Weight Control Behaviors, and Body Dissatisfaction

This study examined associations between suicidal behaviours & extreme & less extreme weight control behaviours, body dissatisfaction, & weight status in adolescents. Data were drawn from Project EAT, a survey of 4,746 Grade 7-12 students. Multivariate logistic regressions examined associations. Suicide ideation & suicide attempts were more commonly observed in adolescents with extreme weight control[…]

Body Mass Index and Attempted Suicide: Cohort Study of 1,133,019 Swedish men

The authors explored body mass index-attempted suicide associations in a cohort of 1,133,019 Swedish men born between 1950-1976, with body mass index measured in early adulthood. During a mean follow-up of 23.9 years, 18,277 men had at least 1 hospital admission for attempted suicide. After adjustment for confounding factors, there was a stepwise, linear decrease[…]
