A latent class analysis of health lifestyles and suicidal behaviors among US adolescents

Suicidal Behavior in Adolescents: A Latent Class Analysis

“…For example, Jung et al [55] developed a study in which three latent profiles were identified as a function of internalizing and externalizing problems. Similarly, studies using an LCA approach showed a relationship between the risk of suicide and other variables related to lifestyle, such as pattern of sleep, physical exercise, and drug use [2,[32][33][34][35]. The results revealed that health-promoting behaviors, a regular diet, and moderate exercise had a protective impact on adolescents' suicidal behaviors by decreasing the ultimate suicide risk [33].…”

In the same line, the work by King et al [35] showed that adolescents with a higher risk of suicide reported higher levels of alcohol and drug consumption and aggressive impulses.…”

“…Although the number of groups were different to that of the present work, the authors found four groups of individuals on the basis of the suicide attempts (acts), suicide ideation, and the risk of suicide when considering the association between suicidal behavior and other related variables. In another study, Xiao et al [33] acknowledged four distinct groups of adolescents according to 13 health indicators and observed that those groups with lower levels of engagement in health-promoting behaviors also displayed higher risks of suicide. Likewise, research on adults at suicide risk using a LC approach also showed distinct subgroups of individuals [31,56,57].…”

“…Some works focused on identifying the precipitating thoughts of death and suicide among adolescents [23,24], or recognizing functioning patterns of risk factors [25,26], whilst others aimed at predicting suicidal behaviors [27], or exploring the subtypes of psychiatric disorders that were strongly associated with suicidal thoughts or behaviors [28,29]. At present, there are several studies that examined the heterogeneity among individuals with varying histories of suicidal behavior [9,24,[30][31][32][33]. Mixture modelling has been employed in adolescent populations [32][33][34][35][36].…”

Mixture modelling has been employed in adolescent populations [32][33][34][35][36]. For instance, Jiang et al [32] identified four groupings for a representative sample of adolescents: (1) emotionally healthy, (2) considered and planned suicide, (3) attempted suicide and (4) planned and attempted suicide.…”
