A Comparison of Alcohol Use and Correlates of Drinking Patterns among Men and Women Aged 50 and Above in Ghana and South Africa

Alcohol use is an important part of the health profile of older adults, and little is known about the prevalence and correlates of drinking among this population in Ghana and South Africa. This study aimed to describe and compare the prevalence and correlates of drinking patterns among adults aged 50 and above in Ghana and South Africa, and to determine which correlates explain differences in drinking patterns between the two countries. We used data from the WHO Study on global AGEing and adult health (SAGE) conducted in Ghana and South Africa. The sample of participants aged 50+ was 4289 in Ghana and 3666 in South Africa. Alcohol measures included a self-report of the number of standard drinks consumed over the previous 7 days, from which we constructed the mutually exclusive drinking categories of lifetime abstainers, low risk and at risk drinkers by gender. We used multivariate analysis to identify independent correlates for the different drinking patterns and those contributing to drinking differences between countries. Lifetime abstainers comprised 41.9% and 74.6% of the Ghana and South Africa samples, respectively. Among current drinkers, there were significantly more at risk drinkers among both genders in South Africa compared to Ghana. Factors independently associated drinking patterns differed between countries and by gender, although similarities included religion and smoking. Smoking status contributed to the difference in drinking patterns between Ghana and South Africa more than socio-demographics. Different patterns of drinking and associated correlates exist among older adults between Ghana and South Africa, and differences in drinking patterns were more strongly associated with smoking than socio-demographics. Drinking may increase in Ghana as economic development continues, although other health behaviors such as smoking may also play an important role and should be monitored in future surveys

Mars Analog Site Study (MASS)

Many proposed missions to Mars involve landing vehicles, including the Mars 94/96 (Russia), Mars Environmental Survey (MESUR, US), and the Marsnet (ESA) missions. Most landers involve in situ measurements of rock and soil compositions, study of local geology by imaging, and establishment of seismic and meteorological networks. The selection of landing sites on Mars is a complex process that must meet engineering constraints and scientific objectives, using available and anticipated data. The goal of the MASS project is to conduct an 'end-to-end' test of the site selection process using Earth analogs

Nomad rover field experiment, Atacama desert, Chile 2. Identification of paleolife evidence using a robotic vehicle: Lessons and recommendations for a Mars sample return mission

This is the publisher's version, also available electronically from "http://onlinelibrary.wiley.com".During the Nomad Rover Field Experiment in the Atacama Desert (Chile), a potential fossil was identified in a boulder by the science team remotely located at NASA Ames Research Center, California. The science team requested the collecting of the boulder that was returned for laboratory analysis. This analysis confirmed the evidence of paleolife. As the first fossil identified and sampled by a remotely located science team using a rover, we use the case of sample I-250697 to describe the process, both in the field and later in the laboratory during the rock analysis, which led to the identification, characterization, and confirmation of the evidence of paleolife evidence in I-250697. We point out the lessons that this case provides for future Mars sample return missions

Axis I and II disorders as long-term predictors of mental distress: a six-year prospective follow-up of substance-dependent patients

<p>Abstract</p> <p>Background</p> <p>A high prevalence of lifetime psychiatric disorders among help-seeking substance abusers has been clearly established. However, the long-term course of psychiatric disorders and mental distress among help-seeking substance abusers is still unclear. The aim of this research was to examine the course of mental distress using a six-year follow-up study of treatment-seeking substance-dependent patients, and to explore whether lifetime Axis I and II disorders measured at admission predict the level of mental distress at follow-up, when age, sex, and substance-use variables measured both at baseline and at follow-up are controlled for. </p> <p>Methods</p> <p>A consecutive sample of substance dependent in- and outpatients (n = 287) from two counties of Norway were assessed at baseline (T1) with the Composite International Diagnostic Interview (Axis I), Millon's Clinical Multiaxial Inventory (Axis II), and the Hopkins Symptom Checklist (HSCL-25 (mental distress)). At follow-up (T2), 48% (137/287 subjects, 29% women) were assessed with the HSCL-25, the Alcohol Use Disorders Identification Test, and the Drug Use Disorders Identification Test. </p> <p>Results</p> <p>The stability of mental distress is a main finding and the level of mental distress remained high after six years, but was significantly lower among abstainers at T2, especially among female abstainers.

Impact of comorbid psychiatric disorders on the outcome of substance abusers: a six year prospective follow-up in two Norwegian counties

BACKGROUND: Most help-seeking substance abusers have comorbid psychiatric disorders. The importance of such disorders for the long-term course of substance abuse is, however, still unclear. The aim of this paper is to describe six-year outcomes regarding death and relapse among alcoholics and poly-substance abusers and to analyse the predictive value of lifetime psychiatric disorders on relapse. METHODS: A consecutive sample of substance-dependent patients who received treatment in two counties in Norway (n = 287) was followed up after approximately six years. Information on socio-demographics, Axis I (CIDI) and II disorders (MCMI-II) and mental distress (HSCL-25) was gathered at baseline. At follow-up, detailed information regarding socio-demographics, use of substances (AUDIT and DUDIT) and mental distress (HSCL-25) was recorded (response rate: 63%). RESULTS: At six-year follow-up, 11% had died, most often male alcoholics (18%). Among the surviving patients, 70% had drug or alcohol related problems the year prior to follow-up. These patients were, classified as "relapsers". There were no significant differences in the relapse rate between women and men and among poly-substance abusers and alcoholics. The relapsers had an earlier onset of a substance use disorder, and more frequently major depression and agoraphobia. Multivariate analysis indicated that both psychiatric disorders (major depression) and substance use factors (early onset of a substance use disorder) were independent predictors of relapse. CONCLUSION: For reducing the risk of long-term relapse, assessment and treatment of major depression (and agoraphobia) are important. In addition, we are in need of a comprehensive treatment and rehabilitation program that also focuses on the addictive behaviour

Psychometric Properties of the Drug Use Disorders Identification Test (DUDIT) in Heroin Dependent Adults and Adolescents with Drug Use Disorder

Objective:The aim of the present study was to evaluate the psychometric properties of the Drug Use Disorders Identification Test (DUDIT), developed to screen individuals for drug problems, in Turkish patients with drug use disorder

Associations Between Quality of Life and Functioning in an Assertive Community Treatment Population

Objective: Level of functioning is positively associated with subjective quality of life for people with severe mental illness, but a detailed relationship between functioning and satisfaction with various life domains is largely unknown, and this gap prompted this study. Methods: Demographic and clinical data were obtained from 149 patients engaged with 12 assertive community treatment teams in Norway. Multivariate regression analyses were used to explore associations between subjective quality of life and patient characteristics. Results: Analyses confirmed positive associations between quality of life and age, functioning, and weekly contact with family and friends and a negative association with anxiety and depressive symptoms. Positive associations between several areas of practical and social functioning and satisfaction with related life domains also were found. Conclusions: Although a causal direction of the associations between functioning and life satisfaction has not been determined in this study, the positive findings might indicate that programs aiming to improve functioning could affect patients’ quality of life
