This study explores the association between PIU and depressive symptoms among adults at high-risk of cannabis use disorder, a relationship insufficiently explored despite the high prevalence of these conditions…
Open article record in new tab ↗BackgroundHistorically, U.S. adolescent boys have reported higher substance use than girls, but this has changed in recent years with girls reporting more use. The reasons for this demographic shift are unclear, but girls may be more likely to turn to substance use as a way to cope with stress and internalizing problems.MethodsWe used cross-sectional data from the 2023 Nevada Middle School Youth Risk Behavior Surv…
Background and hypothesis Evidence suggests a complex interplay among childhood trauma (CT), substance use, and psychopathology in psychosis, yet the precise nature of these relationships remains unclear. Network analysis offers distinct advantages for examining these factors simultaneously, as it can capture multidirectional associations across multiple trauma subtypes, substances, and symptoms that conventional…
Introduction This study examines the impacts of anxiety and depressive symptoms on subsequent initiation of alcohol use, cannabis use, and prescription opioid misuse among diverse adolescents attending high schools on or near a Tribal reservation in a rural Great Plains region of the U.S. Methods In collaboration with Emory University and a Great Plains Tribal nation's behavioral health organization, a community r…
Background Cross-sectional studies have identified health risks associated with epigenetic aging. However, it is unclear whether these risks make epigenetic clocks 'tick faster' (i.e. accelerate biological aging). The current study examines concurrent and lagged within-person changes of a variety of health risks associated with epigenetic aging. Methods Individuals from the Great Smoky Mountains Study were followe…
Open article record in new tab ↗Type 2 diabetes (T2D) has been occurring at younger ages of onset around the world. Indias population accounts for nearly 20% of the global disease burden. This study investigated the occurrence of depressive symptoms and qualitatively explored the lived experiences of 20 young adults living with T2D under the age of 35. We conducted a convergent mixed-methods study with the Patient Health Questionnaire (PHQ-9) an…
BackgroundUnhealthy lifestyle behaviours are becoming increasingly common and might contribute to the growing burden of mental disorders in adolescence. We examined the associations between a comprehensive set of lifestyle behaviours and depression and anxiety in middle adolescents.MethodsSchool-based survey responses were collected from 24,274 Canadian high school students at baseline and 1-year follow-up (averag…
The dual pathway hypothesis of risk for substance use was tested by examining risk from symptoms of conduct problems and depressive symptoms in adolescence (from ages 10-11 to 17-18 years) to substance use—including tobacco, alcohol, cannabis, and other illicit drugs—in both early adulthood (approximately from ages 20 to 29 years) and middle adulthood (approximately from ages 29 to 38 years). Hypotheses were teste…
Open article record in new tab ↗While the COVID-19 pandemic impacted young adults’ alcohol use patterns, little is known about how changes in alcohol use may differ across different settings. Our objective was to identify and compare factors associated with changes in alcohol use among young adults in Canada and France during the first year of the COVID-19 pandemic. We conducted an online cross-sectional survey in October–December 2020 with youn…
Objective: The endocannbinoid system and cannabis exposure has been implicated in emotional processing. The current study examined whether regular cannabis users demonstrated abnormal intrinsic (a.k.a. resting state) frontolimbic connectivity compared to non-users. A secondary aim examined the relationship between cannabis group connectivity differences and self-reported mood and affect symptoms. Method: Participa…
To evaluate the consistency of the relationship between early drug use in adolescence and illegal drug use in adulthood as proposed in the "gateway theory" and to determine whether pre-existing depressive symptoms modifies this relationship. We used contractual data from the National Longitudinal Study of Adolescent to Adult health data spanning a 14 year period. We assessed the relationship between gateway drugs…
Open article record in new tab ↗African-American adolescents experience disproportionate rates of negative consequences of substance use despite using substances at average or below-average rates. Due to underrepresentation of African-American adolescents in etiological literature, risk and protective processes associated with their substance use require further study. This study examines the role of parental support in adolescents’ conduct prob…
