Patterns of alcohol use between genders: A cross-cultural evaluation

Introduction: Alcohol use by men and women is very much influenced by social habits and customs. Cultural peculiarities and biological differences between the sexes require more focused and standardized studies. The objective was to systematize information on patterns of alcohol use between the sexes.Method: A literary review (1972-2004) identified 96 publications (Lilacs, Scielo, Medline) and some related books.Results and conclusions: Men drank more and presented more problems (legal, family, social, clinical, traumas and mortality) associated with alcohol use; the consequences of alcohol use in developing countries with low death rates is even higher. Women can face more discrimination by using alcohol as well as worse health problems when they abuse drinking (liver, pancreas, and central and peripheral nervous system problems, psychiatric comorbidity, etc.); sexual abuse is more commonly associated with women than discussing the different responses to treatment. As for social roles/responsibilities exercised by women, there are indications that marriage, employment, and children have a good influence, discouraging alcohol use, while divorce, unemployment, and no children contribute to higher consumption. For both sexes, religion was a protective factor for alcohol use; acculturation was a strong influence in the pattern of alcohol use, and alcohol worsened the evolution of existing psychiatric disorders.

Symptom dimensions, clinical course and comorbidity in men and women with obsessive-compulsive disorder

The study aimed to compare male and female patients with obsessive-compulsive disorder (OCD) across symptom dimensions, clinical course and comorbidity. A cross-sectional study was undertaken with 858 adult OCD patients (DSM-IV) from the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. Patients were evaluated using structured interviews, including the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) and the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I). The sample was composed of 504 women (58.7%) and 354 men (41.3%) with a mean age of 35.4 years-old (range: 18-77). Men were younger, more frequently single and presented more tics, social phobia and alcohol use disorders. Among men, symptom interference occurred earlier and symptoms of the sexual/religious dimension were more common and more severe. Conversely, women were more likely to present symptoms of the aggressive, contamination/cleaning and hoarding dimension and comorbidity with specific phobias, anorexia nervosa, bulimia, trichotillomania, skin picking and compulsive buying. In the logistic regression, female gender remained independently associated with the aggressive and contamination/cleaning dimensions. In both genders the aggressive dimension remained associated with comorbid post-traumatic stress disorder, the sexual/religious dimension with major depression and the hoarding dimension with tic disorders. Gender seems to be relevant in the determination of OCD clinical presentation and course and should be considered an important aspect when defining more homogeneous OCD subgroups. © 2012 Elsevier B.V.

The association between low alcohol use and traffic risk behaviors among Brazilian college students

Although there are a large number of studies focused on binge drinking and traffic risk behaviors (TRB), little is known regarding low levels of alcohol consumption and its association to TRB. The aim of this cross-sectional study is to examine the association of low to moderate alcohol intake pattern and TRB in college students in Brazil. 7037 students from a National representative sample were selected under rigorous inclusion criteria. All study participants voluntarily fulfilled a structured, anonymous, and self-questionnaire regarding alcohol and drug use, social-demographic data, and TRB. Alcohol was assessed according to the average number of alcoholic units consumed on standard occasions over the past 12 months. The associations between alcohol intake and TRB were summarized with odds ratio and their confidence interval obtained from logistic regression. Compared with abstainers students who consumed only one alcohol unit had the risk of being a passenger in a car driven by a drunk driver increased by almost four times, students who reported using five or more units were increased by almost five times the risk of being involved in a car crash. Compared with students who consumed one alcohol unit, the risk of driving under the influence of alcohol increased four times in students using three alcohol units. Age group, use of illicit drugs, employment status, gender, and marital status significantly influenced occurrence of TRB among college students. Our study highlights the potential detrimental effects of low and moderate pattern of alcohol consumption and its relation to riding with an intoxicated driver and other TRB. These data suggest that targeted interventions should be implemented in order to prevent negative consequences due to alcohol use in this population. (C) 2012 Elsevier Inc. All rights reserved,

Optimizing heroin-assisted treatment (HAT): Assessment of the contribution of direct ethanol metabolites in identifying hazardous and harmful alcohol use

Heavy alcohol consumption may accelerate the progression of hepatitis C-related liver disease and/or limit efforts at antiviral treatment in opioid-dependent patients receiving heroin-assisted treatment (HAT). Our study aims to assess alcohol intake among HAT patients by self-reports compared to direct ethanol metabolites.

Cannabis use disorder and age at onset of psychosis--a study in first-episode patients

INTRODUCTION Age at onset of psychosis (AAO) may be younger in patients with cannabis use disorders (CUD) compared to those without CUD (NCUD). Previous studies included CUD co-morbid with other substance use disorders (SUD), and many did not control for confounders. METHODS Controlling for relevant confounders, differences in AAO between patients with and without CUD excluding those with any other SUD were analyzed in a large representative file audit of 625 first-episode psychosis (FEP) patients (age 14 to 29years) admitted to the Early Psychosis Prevention and Intervention Centre in Melbourne, Australia. RESULTS Three quarters of the 625 FEP patients had a CUD. Cannabis use started before psychosis onset in 87.6% of patients. AAO was not significantly different between CUD (without other SUD, n=201) and NCUD (n=157). However, AAO was younger in those with early CUD (starting age 14 or younger) compared to NCUD (F(1)=5.2; p=0.024; partial η(2)=0.026). Earlier age at onset of cannabis use predicted earlier age at onset of psychosis (β=-0.49, R(2)-change=0.25, p<0.001). CONCLUSION Only CUD starting age 14 or younger was associated with an earlier AAO at a small effect size. These findings suggest that CUD may exert an indirect effect on brain maturation resulting in earlier AAO potentially only in cannabis sensitive subjects.

Treatment outcomes of an integrated residential programme for patients with schizophrenia and substance use disorder

About half of all schizophrenic patients have a co-occurring substance use disorder, leading to poorer social and functional outcomes than obtained in non-abusing patients. To improve outcomes, integrated treatments have been designed that address the two conditions simultaneously. Results are, however, conflicting because the available effect studies are hampered by various methodological issues, among which are heterogeneous patient samples.
