Abstract
Many of the various factors, characteristics, and variables involved in the addictive process can determine an individual’s vulnerability to develop drug addiction. Hedonic eating, based on pleasure rather than energy needs, modulates the same reward circuits, as do drugs of abuse. According to the last report of the World Health Organization, the worldwide obesity rate has more than doubled since 1980, reaching especially critical levels in children and young people, who are overexposed to high-fat, high-sugar, energy-dense foods. Over the past few decades, there has been an increase in the number of studies focused on how eating disorders can lead to the development of drug addiction and on the comorbidity that exists between the two disorders. Herein, we review the most recent research on the subject, focusing especially on animal models of binge eating disorders and drug addiction. The complex profile of patients with substance use and binge eating disorders requires an integrated response to dually diagnosed patients. Nutritional patterns should be considered an important variable in the treatment of substance use disorders, and future studies need to focus on specific treatments and interventions in individuals who show a special vulnerability to shift from one addiction to the other.

Minoyan N, Høj SB, Jutras-Aswad D, Vlad D, Martel-Laferrière V, Sylvestre MP, Bruneau J. Gender-specific associations between psychological distress and injecting risk behaviours among people who inject drugs in Montreal, Canada. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103319. [PMID: 34154905 DOI: 10.1016/j.drugpo.2021.103319] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 05/15/2021] [Accepted: 05/24/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Psychological distress is common among people who inject drugs (PWID) and may be associated with HCV-related risk behaviours. Previous studies have documented increased vulnerability to both psychological distress and HCV infection among female relative to male PWID. It is, however, unclear whether behavioural responses to distress differ by gender. This study estimated gender-specific associations between psychological distress and i) binge drug injection, and ii) sharing of injection materials. METHODS Data were drawn from HEPCO, a longitudinal cohort study involving three-monthly interviews with active PWID in Montreal, Canada. Past-month psychological distress was assessed with the Kessler (K10) scale, categorized for descriptive analyses as minimal (score 10-15), moderate (16-21), high (22-29), or severe (30-50). Binge was defined as injecting large quantities of drugs until participants could no longer continue (past 3 months). Sharing was defined as injection with previously-used needles or equipment (past 3 months). Generalized additive models were fit to estimate smooth, nonlinear associations between K10 scores and risk behaviours, by gender. Models were adjusted for known determinants of drug-related harms and included random intercepts to model within-subject correlation. RESULTS 805 individuals (82% male) provided 8158 observations (2011-2020). High to severe levels of distress were common and more frequent among women (55% vs 37%). Among men, the odds of binge and sharing monotonically and non-linearly increased with increasing scores of psychological distress. Associations for binge among women were attenuated relative to men but nevertheless increased with distress, albeit in a linear fashion. Sharing was not associated with distress among women. CONCLUSION Psychological distress was differentially associated with injecting risk behaviours among men and women who inject drugs. Assessment of distress may provide novel prevention opportunities for select PWID. Further investigation into gender differences is warranted to inform development and tailoring of interventions.

The association between quantity, frequency and duration of cocaine use during the heaviest use period and DSM-5 cocaine use disorder. Drug Alcohol Depend 2020; 213:108114. [PMID: 32563848 DOI: 10.1016/j.drugalcdep.2020.108114] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 06/02/2020] [Accepted: 06/06/2020] [Indexed: 01/03/2023]
Abstract
BACKGROUND Quantity (Q), frequency (F), and duration (D) of cocaine use during a person's heaviest use period are important aspects of cocaine use patterns that associated with cocaine use disorder (CocUD). METHODS A total 2988 lifetime cocaine users who met CocUD after the onset of cocaine heaviest use were identified from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). QFD were each categorized into four levels. Hierarchical regressions were used to examine the association between QFD of cocaine use and CocUD. Two-way interactions between QFD were also examined. RESULTS As the level of cocaine use increased from low to very high, the prevalence of CocUD increased. Compared to people with low F, cocaine users with very high F were 12.09 times (95 %CI 6.33, 23.07) as likely to meet criteria for CocUD. Similarly, Q was associated with 4.84 (95 %CI 2.55, 9.18) times the risk of CocUD. D was not significantly associated with the risk of CocUD. Significant additive interaction was identified between Q*F on CocUD prevalence. Approximately one-third of the excess risk associated with having high Q & high F was due to the interactive effect. CONCLUSION Of these three cocaine use patterns, F had the strongest association with CocUD, followed by the Q. High Q and high F was a very dangerous pattern of cocaine use as the combination had as a synergistic effect on the risk of CocUD. It is important for intervention programs to focus on the reduction of both Q and F.
