National prevalence rates of suicidal ideation and suicide attempts among adults with and without depression

Abstract

Background: This study examines the national prevalence rates of suicidal ideation and attempts among adults with and without major depressive episode (MDE) in five demographic groups –race, sex, age, education, and marital status – in the United States. Methods: Data extracted from the 2018 National Survey on Drug Use and Health (NSDUH) were analyzed , producing 42,551 records. Wald chi-square diagnostic examination was conducted on the multinomial logistic regression (MLR) model with five demographic predictor variables.Results: The highest rates of suicidal ideation for those with MDE occurred in White females (40.6%), adults 18-25 years old (36.4%), individuals with some college education (40.4%), and unmarried adults (57.1%). For those without MDE, the highest rates of suicidal ideation occurred among White males (31.9%), adults 18-25 years old (31.9%), individuals with some college education (38.7%), and unmarried adults (49.6%). Among the same demographic groups, proportions of suicide attempts were highest for those with MDE. A chi-square test indicated significant differences across adults with and without MDE in all demographic groups. The MLR model fitting results showed that the five demographic variables were significant predictors of suicidal ideation and attempts in both populations (p<0.05).Limitations: Our data are cross-sectional and no directionality or causality can be assumed between study variables. A small proportion of the population was excluded from the survey.Conclusions: serious mental health needs are unmet for many demographic groups, especially among individuals with depression. Population-based clinical interventions are needed to reduce rates of depression, suicidal ideation, and attempts.

Factors Related to the Level of Depression and Suicidal Behavior Among Men With Diagnosed Depression, Physically Ill Men, and Healthy Men

“…In the study of Griffiths et al (88) for single and divorced men aged 25 and over, suicide rates were around three times higher than for married men throughout 1983-2004. Results of Omary (71) suggested that marriage might play a protective role for suicidal ideation among men with depression. Our results present a completely different dimension-bachelor status is a characteristic protective factor for suicidal behavior among men with diagnosed depression.…”

Adolescent mobile phone addiction during the COVID-19 pandemic predicts subsequent suicide risk: a two-wave longitudinal study

“…In addition to the association with mobile phone addiction, depression and sleep disorders have also been associated with suicidality [45][46][47]. For example, Bernert et al 's (2015) systematic review concluded preliminary, converging evidence that sleep disturbances were an empirical risk factor for suicidal behaviors.…”

“…Therefore, there seems to be a vicious cycle between mobile phone addiction and depression and subsequent suicidality risk [41]. As depression has long been recognized as one of the most critical risk factors for suicide prediction [45,47], more attention needs to be paid to its presence when screening people with mobile phone addiction and the intervening suicidality. As it may be challenging to evaluate the severity of the negative influence of mobile phone addiction and when and how to implement an intervention, the presence of depression could be a valuable warning sign; that is, greater attention should be focused on adolescent mobile phone addicts who also have depressive symptoms.…”
