An Epidemiologic, Longitudinal, and Discordant-Twin Study of the Association Between Gambling Disorder and Suicidal Behaviors.

ABSTRACT: Gambling disorder is associated with suicidal behaviors, but it is not clear whether the association is due to common etiologic factors or to gambling disorder being causally related to suicidality. This question was examined from epidemiologic, longitudinal, and discordant twin study perspectives. The results suggested that the causes of the association with disordered gambling differed for suicidal ideation, plan, and attempt, and differed for men and women. The association of suicidal thoughts with disordered gambling was non-causally explained by common genetic influences among women (but not men). Conversely, there was evidence consistent with a potentially causal influence of disordered gambling on suicide attempt among men (but not women), which might have been related to gambling-related financial problems. The use of monetary data to identify individuals experiencing financial harms associated with their gambling may represent a more practicable target for screening, intervention, and prevention and may reduce gambling-related financial crises, thereby warding off a potential gambling-related suicide attempt.

Project description:BackgroundRecent studies show migraineurs are at an increased risk of developing suicidal behaviors, even after controlling for comorbid depression. However, previous research has not examined the impact of psychiatric mood disorders on suicidal behaviors in migraineurs within a nationally representative sample.ObjectiveA cross-sectional study was used to investigate the association between migraine and suicidal behaviors and determine whether psychiatric comorbidities modify this association in a nationwide inpatient cohort.MethodsWe analyzed the Nationwide Inpatient Sample of hospitalizations compiled from USA billing data. Migraine, suicidal behaviors, and psychiatric disorders were identified based on the International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes from hospitalization discharges (2007-2012). Weighted national estimates were used to estimate odds ratios (OR) and 95% confidence intervals (CI).Results156,172,826 hospitalizations were included, of which 1.4% had a migraine diagnosis and 1.6% had a diagnosis of suicidal behavior. Migraineurs had a 2.07-fold increased odds of suicidal behaviors (95%CI: 1.96-2.19) compared with non-migraineurs. We repeated analyses after stratifying by depression, anxiety, or posttraumatic stress disorder (PTSD). Among hospitalizations with depression, migraine was associated with a 20% reduced odds of suicidal behaviors (95%CI: 0.76-0.85). Among hospitalizations without depression, migraine was associated with 2.35-fold increased odds of suicidal behaviors (95%CI: 2.20-2.51). In stratified analyses, we noted that among hospitalizations with anxiety, migraineurs had slightly increased odds of suicidal behaviors (OR: 1.07, 95%CI: 1.02-1.13). Among hospitalizations without anxiety, migraine was associated with a 2.06-fold increased odds of suicidal behaviors (95%CI: 1.94-2.20). Similarly, in analyses stratified by PTSD, migraine was not associated with an increased risk of suicidal behaviors (OR: 1.00, 95%CI: 0.94-1.07) among those with PTSD. However, the odds of suicidal behaviors were increased among hospitalizations without PTSD (OR: 1.95, 95%CI: 1.84-2.08).ConclusionChronic conditions that do not affect the current hospitalization may not have been reported. The presence of psychiatric diagnoses influences associations of suicidal behaviors with migraine in a national inpatient sample. Migraineurs with diagnosed comorbid psychiatric disorders may be receiving care that mitigates their risk for suicidal behaviors.

Project description:AimsTo estimate the effect of recreational legalization on cannabis use frequency and sources of variance across legal environments.DesignLongitudinal discordant twin and gene-environment interaction models in twins recruited from birth records and assessed prospectively.SettingThe United States, including states with different recreational cannabis policies before and after 2014, when recreational cannabis was first legalized.ParticipantsTwo longitudinal, prospectively assessed samples of American twins aged 24-47 (n = 1425 in legal states, n = 1996 in illegal states), including 111 monozygotic pairs discordant for residence.MeasurementsCurrent cannabis use frequency (measured continuously and ordinally) was the primary outcome, and the predictor was recreational status of cannabis (legal/illegal) in the participant's state of residence at the time of assessment. Covariates include age, sex and cannabis use frequency prior to 2014.FindingsAccounting for pre-2014 use, residents of legal states used cannabis more frequently than residents of illegal states (b = 0.21, P = 8.08 × 10-5 ). Comparing 111 pairs of monozygotic twins discordant for residence confirmed the effect (b = 0.18, P = 0.014). There was inconclusive evidence for genetic influences on cannabis use frequency that were specific to the legal environment [χ2 = 2.9 × 10-9 , degrees of freedom (d.f.) = 1, P > 0.999]. Existing genetic influences were moderated by the legal environment, as the genetic correlation between marijuana use before and after legalization was lower in states that legalized (rgenetic = 0.24) compared with states that did not (rgenetic = 0.78, Pdifference = 0.016).ConclusionsIn the United States, there appears to be a ~ 20% average increase in cannabis use frequency attributable to recreational legalization, consistent across increasingly rigorous designs. In addition, the heritability of cannabis use frequency appears to be moderated by legalization.
