Los efectos sobre el medio ambiente en las nuevas democracias, las dictaduras y las democracias tradicionales

El principal objeto de esta investigación es determinar y evaluar si la evolución o transición hacia formas cerradas o abiertas de gobernar -autocracias y democracias- ha llevado aparejada una menor o mayor contribución a la calidad del medio ambiente. La conclusión es clara, los nuevos gobiernos democráticos tienen más probabilidades de responder a los intereses medioambientales y, por lo tanto, son más propensos a respaldar las convenciones internacionales que las autocracias.

Factors associated with favorable drinking outcome 12 months after hospitalization in a prospective cohort study of inpatients with unhealthy alcohol use.

BACKGROUND: Prevalence of unhealthy alcohol use among medical inpatients is high. OBJECTIVE: To characterize the course and outcomes of unhealthy alcohol use, and factors associated with these outcomes. DESIGN: Prospective cohort study. PARTICIPANTS: A total of 287 medical inpatients with unhealthy alcohol use. MAIN MEASURES: At baseline and 12 months later, consumption and alcohol-related consequences were assessed. The outcome of interest was a favorable drinking outcome at 12 months (abstinence or drinking "moderate" amounts without consequences). The independent variables evaluated included demographics, physical/sexual abuse, drug use, depressive symptoms, alcohol dependence, commitment to change (Taking Action), spending time with heavy-drinking friends and receipt of alcohol treatment (after hospitalization). Adjusted regression models were used to evaluate factors associated with a favorable outcome. KEY RESULTS: Thirty-three percent had a favorable drinking outcome 1 year later. Not spending time with heavy-drinking friends [adjusted odds ratio (AOR) 2.14, 95% CI: 1.14-4.00] and receipt of alcohol treatment [AOR (95% CI): 2.16(1.20-3.87)] were associated with a favorable outcome. Compared to the first quartile (lowest level) of Taking Action, subjects in the second, third and highest quartiles had higher odds of a favorable outcome [AOR (95% CI): 3.65 (1.47, 9.02), 3.39 (1.38, 8.31) and 6.76 (2.74, 16.67)]. CONCLUSIONS: Although most medical inpatients with unhealthy alcohol use continue drinking at-risk amounts and/or have alcohol-related consequences, one third are abstinent or drink "moderate" amounts without consequences 1 year later. Not spending time with heavy-drinking friends, receipt of alcohol treatment and commitment to change are associated with this favorable outcome. This can inform efforts to address unhealthy alcohol use among patients who often do not seek specialty treatment.

You, your child and alcohol

You, your child and alcohol is a booklet that offers parents advice and guidance on how to discuss alcohol with their child and encourages them to think about how their relationship with alcohol can influence their children. During June 2010 this booklet was distributed to GP surgeries, pharmacies and local Tesco stores. Community Safety Officers and Police are also distributing the booklet in many areas. You, your child and alcohol is part of campaign developed by the Public Health Agency, the Department of Health, Social Services and Public Safety, the Police Service of Northern Ireland, the Northern Ireland Office and the Northern Ireland Policing Board to tackle the issue of underage drinking.

Reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) imbedded within a general health risk screening questionnaire: results of a survey in 332 primary care patients.

BACKGROUND: Self-administered, general health risk screening questionnaires that are administered while patients wait in the doctor's office may be a reasonable and timesaving approach to address the requirements of preventive medicine in a typical 10-min medical visit. The psychometric characteristics of the Alcohol Use Disorders Identification Test (AUDIT) incorporated within a health questionnaire (H-AUDIT) have not been examined. METHODS: The reliability and validity of the self-administered AUDIT were compared between the H-AUDIT and the AUDIT used as a single scale (S-AUDIT) in 332 primary care patients. RESULTS: No major demographic or alcohol use characteristics were found between the 166 subjects who completed the H-AUDIT and the 166 individuals who completed the S-AUDIT. The test-retest reliability of the 166 subjects who completed the H-AUDIT [estimated by Spearman correlation coefficient at a 6-week interval (0.88), internal consistency (total correlation coefficients for all items ranged from 0.38 to 0.69; Cronbach alpha index 0.85), and the sensitivity and specificity of the H-AUDIT were used to identify at-risk drinkers' areas under receiver operating characteristic (0.77) and alcohol-dependent subjects' areas under receiver operating characteristic (0.89)] was similar to the same measurements obtained with the 166 individuals who completed the S-AUDIT. CONCLUSIONS: The AUDIT incorporated in a health risk screening questionnaire is a reliable and valid self-administered instrument to identify at-risk drinkers and alcohol-dependent individuals in primary care settings.

Missing value imputation in longitudinal measures of alcohol consumption

Attrition in longitudinal studies can lead to biased results. The study is motivated by the unexpected observation that alcohol consumption decreased despite increased availability, which may be due to sample attrition of heavy drinkers. Several imputation methods have been proposed, but rarely compared in longitudinal studies of alcohol consumption. The imputation of consumption level measurements is computationally particularly challenging due to alcohol consumption being a semi-continuous variable (dichotomous drinking status and continuous volume among drinkers), and the non-normality of data in the continuous part. Data come from a longitudinal study in Denmark with four waves (2003-2006) and 1771 individuals at baseline. Five techniques for missing data are compared: Last value carried forward (LVCF) was used as a single, and Hotdeck, Heckman modelling, multivariate imputation by chained equations (MICE), and a Bayesian approach as multiple imputation methods. Predictive mean matching was used to account for non-normality, where instead of imputing regression estimates, "real" observed values from similar cases are imputed. Methods were also compared by means of a simulated dataset. The simulation showed that the Bayesian approach yielded the most unbiased estimates for imputation. The finding of no increase in consumption levels despite a higher availability remained unaltered. Copyright (C) 2011 John Wiley & Sons, Ltd.

Alcohol MOT part one

The Alcohol MOT is designed to support those working in primary care to carry out alcohol brief interventions. There is extensive evidence to show that primary care-based brief interventions are very effective at reducing drinking at both hazardous and harmful levels. MOT Part 1 enables patients to work out if they are drinking at hazardous or harmful levels. MOT Part 2 helps motivate and support patients to reduce their drinking. Both tools are designed so that a practitioner can work through them with a patient, or a patient can work through them alone.

PHA urges 'freshers' to be smart and know their alcohol limits

As 'fresher's week' commences, the Public Health Agency is encouraging students across Northern Ireland to avoid binge drinking and to know their limits if they do choose to drink alcohol.Enjoying new freedoms, at college or university, means taking care of yourself and others and, if you choose to drink, staying within safe alcohol limits. Owen O'Neill, PHA Health and Social Wellbeing Improvement Manager for drugs and alcohol, said: "Some young people may drink more when they leave home, or join their friends in college or university for the first time. They might think that, as young people, they don't have to take care with alcohol, but staying within the safe drinking limits is important for everyone who drinks. Excessive and binge drinking can have lasting effects on health, such as damage to the liver, heart, brain and stomach. Drinking too much can also increase the risk of accidents and antisocial behaviour as well as sexually transmitted infections and unplanned pregnancy"."We would also strongly advise against drinking games. Although they are regarded as a 'bit of fun', in reality they can be very dangerous. As an extreme form of binge drinking, where large quantities of alcohol are consumed in a very short time, drinking games can result in alcohol poisoning, leading to brain damage, coma or death. The PHA encourages students to enjoy their new student life, but urges them to be aware of their alcohol intake and drink responsibly, especially throughout fresher's week, with the many cheap drink promotions currently available."Daily alcohol limits are recommended by the government in order to avoid the risks of excessive and binge drinking in any one session. These are:Men: No more than 3 to 4 units of alcohol a day and no more than 21 units over the course of the week.Women: No more than 2 to 3 units of alcohol a day and no more than 14 units over the course of the week.Examples of units:Can of extra strong lager - 4 unitsBottle of lager - 1.5 unitsPint of standard lager - 2.5 unitsPint of premium larger - 3 unitsSmall pub bottle of wine - 2.25 units70cl bottle of wine - 7 to 10 unitsStandard 275ml of alcopops - 1.5 to 1.8 units70cl bottle of alcopops - 3.75 to 4.5 unitsPub measure of spirits - 1.5 unitsPint of cider - 3 unitsPint of stout - 2.5 unitsIf you do choose to drink alcohol:DON'T:Ever drink and driveDrink on an empty stomachMix alcohol with other drugsDrink in rounds as this may speed up your drinkingLeave your drinks unattendedDO:Take sips rather than gulpsAlternate each alcoholic drink with a non alcoholic drink e.g. water or a soft drinkSet yourself a limit and try to stick to it (refer to daily alcohol limits) Take frequent breaks from drinking to give your body time to recoverTell friends and family where you are going and who you will be withRemember, that for each unit you drink over the daily limit, the risk to your health increases. It's important to spread the units throughout the week - you can't 'save up' your units for the weekend or your holiday. It is also important to drink plenty of water, ideally matching the amount of alcohol you have consumed.So students make smart choices this term - drink sensibly and know your limits!For further information on sensible drinking and alcohol units visit the Public Health Agency's website www.knowyourlimits.info

PHA reinforce sensible drinking in Alcohol Awareness Week

Recent health figures show that 20% of adults surveyed admitted to drinking over the weekly alcohol limits (1)so the Public Health Agency is using Alcohol Awareness Week (14-20th November) to reinforce the importance of drinking sensibly and staying within safe alcohol limits.Government guidelines on safe drinking are 21 units per week for males and 14 units per week for females. Staying within these limits is important as excessive and binge drinking can lead, in the short term, to increased risk of accidents, antisocial behaviour, impact on relationships, unplanned pregnancy. Longer term it can damage the liver, heart, brain and stomach, not to mention the other human costs, and costs to the economy and society as a whole.Owen O'Neill, PHA Health and Social Wellbeing Improvement Manager and Drugs and Alcohol Lead, said: "The Department of Health, Social Services and Public Safety's drinking limits are in place to encourage the public to develop safe and sensible drinking habits. However, these recent figures highlight that not everyone is adhering to these limits. It is crucial that those who do decide to have a drink do so in moderation and stick to the recommended limits to prevent any long or short term damages".The message is clear, if you drink, remember to be smart and enjoy alcohol within safe limits. People should follow the recommended daily alcohol intake. These are:Men: No more than 3 to 4 units of alcohol a day and no more than 21 units over the course of the week.Women: No more than 2 to 3 units of alcohol a day and no more than 14 units over the course of the week.Examples of units:Can of extra strong lager - 4 unitsBottle of lager - 1.5 unitsPint of standard lager - 2.5 unitsPint of premium larger - 3 unitsSmall pub bottle of wine - 2.25 unitsPub measure of spirits - 1.5 unitsPint of cider - 3 unitsPint of stout - 2.5 units. Remember, that for each unit you drink over the daily limit, the risk to your health increases. It's important to spread the units throughout the week - you can't 'save up' your units for the weekend or an upcoming holiday. It is also important to drink plenty of water, ideally matching the amount of alcohol you have consumed.For further information on sensible drinking and alcohol units visit the Public Health Agency's website www.knowyourlimits.infoReference(1) Health Survey Northern Ireland: first results from the 2010/2011 survey (2011) DHSSPS, http://dhsspsni.giv/index/stats_research/stats-public-health.htm

Personality factors and alcohol use: a mediator analysis of drinking motives.

Current evidence on the association between personality factors, drinking motives, and alcohol use comes exclusively from North America. The present study, however, is based on a sample of 2090 Swiss college students (mean age 23.5, SD = 2,9) and investigates by means of structural equation modeling whether drinking motives mediate the association between personality factors and alcohol use. The results revealed that extraversion was positively related to drinking for enhancement motives; conscientiousness was negatively related to both enhancement and coping motives; and neuroticism was positively related to drinking for coping motives. The association between extraversion and alcohol use was mediated by enhancement motives, while the negative association between conscientiousness and alcohol use was partially mediated by both enhancement and coping motives. This concurs with the findings of North American studies. However, in contrast to these findings, our study finds that coping motives attenuate the "protective" effect of neuroticism with regard to alcohol use. Taken together, the study indicates that alcohol use serves specific purposes depending on particular personality traits. The finding that personality-related effects are partially mediated by motives increases the likelihood that motive-based preventive efforts will help reduce alcohol use among young adults who display particular personality traits.

Risky single occasion drinking frequency and alcohol-related consequences: can abstinence during early adulthood lead to alcohol problems?

QUESTIONS UNDER STUDY: the main purpose of this longitudinal study was to determine the impact of risky single occasion drinking (RSOD) frequency on alcohol dependence and drinking consequences reported 15 months later. METHODS: As a baseline sample, 5,990 young men were assessed on their drinking habits including the frequency of RSOD. Of them, 5,196 were reassessed at follow-up 15 months later on RSOD frequency, alcohol dependence and alcohol related consequences in thze interceding year. Drop out biases were investigated. RESULTS: Around 45% of the baseline participants reported regular RSOD (every month or more frequently). Despite the fact that RSOD distribution was generally stable during the initial sample, 47.4% reported a variation of their RSOD frequency 15 months later. Around 25% of the sample reported reduced RSOD frequency. Nonetheless, occasional RS drinkers were more likely to become regular (monthly) RSO drinkers at follow up. Daily and weekly RSOD were associated with high proportions of alcohol dependence and detrimental consequences of drinking. Surprisingly, abstainers at baseline were more likely to be at risk of alcohol dependence and consequences at follow up than non-RSO drinkers. CONCLUSIONS: Despite the fact that alcohol abstinence is logically the best way to avoid the detrimental consequences of alcohol drinking, abstainers at baseline reported as many problems due to alcohol use at follow up as occasional or monthly RSO drinkers. The few participants who had become RSO drinkers during the follow up period were indeed likely to engage in detrimental behaviour. Non-RSO drinkers had the fewest problems due to alcohol use. This substantiates the early occurrence of drinking consequences among inexperienced RSO drinkers.

A Brief Cognitive Behavioural Therapy Alcohol Intervention Programme is an Effective Secondary Prevention Approach for New Employees entering an Irish Workforce: A Pilot

The prevalence of unhealthy drinking at all levels in Irish society poses serious issues in terms of the consequence to individuals concerned, as well as to society as a whole. The workplace offers a useful setting for early identification and intervention with new employees who may have pre-existing alcohol use disorder issues. This pilot study aimed to evaluate the effectiveness within the workplace of a brief Cognitive Behavioural Therapy (CBT) intervention in reducing participants binge and risky drinking behaviours. Twenty-six Irish Naval recruits volunteered to participate in this randomised controlled trial. The intervention was conducted over four consecutive one and a half hour weekly sessions. Participants completed four principle outcome measures at intake, termination of the intervention and at the two-month follow-up assessment. The Alcohol Use Disorders Identification Test (Babor, Higginis-Biddle, Saunders & Monterio, 2001) was used to measures participants’ consumption levels and frequency of binge or risky drinking. A Readiness Ruler (Miller, Zweben, Diclemente, & Rychtarik, 1992) was used to measure participants’ readiness to change drinking, while the Drinking Expectancy Questionnaire (Young & Oei, 1996) was used to measure participants’ beliefs pertaining to alcohol, and their ability to refuse alcohol in high-risk social surroundings. There were preliminary data in support of the intervention. There were interaction effects that approached statistical significance for both a reduction in participants’ binge drinking (p =. 064) and an increase in participants’ ability to refuse alcohol in high-risk social settings (p = .059). There was also a significant interaction effect (pThis resource was contributed by The National Documentation Centre on Drug Use.
