Risk factors for alcohol dependence: a questionnaire survey

Several factors, known to associate with alcoholism, have not been studied together earlier as determinants of alcohol dependence, and taking into account possible interactions. A representative sample of 302 male and 312 female Finns, aged 19 to 81 years, answered a computerized questionnaire in January 1996. The diagnosis of alcohol dependence was based on the ICD-10 criteria. There were 66 (10.8%) subjects with current (past 12-month) ICD-10 alcohol dependence. After adjusting for other potential correlates in logistic regression analysis, alcohol dependence was more common among subjects high on both asocial behavior and on thinking that his or her behavior is determined mainly by chance or by other people (external control) than among the rest [odds ratio (OR) 4.4; 95% confidence interval (95% CI) 1.8-10.9]. Likewise, alcohol dependence was more common among subjects who recalled that they were highly stimulated when intoxicated by alcohol (OR 3.4; 95% CI 1.9-6.0). High predisposition to anxiety associated strongly with alcohol dependence among males (OR 13.8; 95% CI 4.4-43.1), but not among females (OR 2.5; 95% CI 0.7-9.1). Several of the aforementioned correlates may be modifiable risk factors for alcohol dependence.     

Prevalence of alcohol dependence and abuse in general practice

The aim of this study is to deliver representative epidemiological data about the prevalence of alcohol abuse and dependence in general practices in an urban area. In 12 general practices at Luebeck, a Northern German city with 220,000 inhabitants, a total of 929 patients (aged between 14 and 75 years) were screened using the CAGE and the Short Michigan Alcoholism Screening Test. If one of these screening questionnaires or the General Practitioners' assessment of the patient indicated an alcohol problem, the patient underwent a standardized diagnostic interview using the alcohol section of the Schedules for Clinical Assessment in Neuropsychiatry. The prevalence rates according to ICD-10 or DSM-III-R were 3.5% for alcohol abuse and 7.2% for alcohol dependence, the sex ratio was 1:2.8 (female:male). These results are compared with previous findings, and general epidemiological implications of this study are discussed.     

Performance of screening instruments for identifying alcohol dependence in the general population, compared with clinical populations

Screening instruments for problem drinking have been developed in clinical populations, and little is known of their performance in the general population. Sensitivity and specificity of the CAGE and the TWEAK for ICD-10 and/or DSM-IV criteria for alcohol dependence are compared among those sampled from the southern region in the 1995 National Alcohol Survey (n = 776), and from emergency room (ER) (n = 1327) and primary care clinic (n = 767) samples in Jackson, MS. Sensitivity of the CAGE was higher in both the ER (85%) and primary care (82%) samples than in the general population (75%), although differences were not significant, and this held for males and females alike. Sensitivity of the TWEAK was lower in the general population sample (83%) than in the ER sample (89%), but higher than in the primary care sample (75%). In the general population, sensitivity of both screeners was better (although not significantly so) among those making an ER or primary care visit during the last year than among those not doing so, with the largest difference found for the CAGE (85% vs. 65%, respectively). In a merged sample of the three sites, the interaction of site by screening instrument was not a significant predictor of alcohol dependence for either the CAGE or TWEAK. Data suggest that screening instruments may not perform as well in the general population as in some clinical populations, with more variation apparent across groups for some screeners than for others. Although further analysis is necessary to explore this issue further, attention should be given to selection of the best instrument for use in a given population.     

DSM-IV alcohol disorders in a general population sample of adolescents and young adults

AIMS/DESIGNS: As part of the Early Developmental Stages of Psychopathology (EDSP) study, results from the baseline cross-sectional assessment of DSM-IV alcohol disorders are presented for a sample of 14-24-year-olds residents in Munich, Germany (N = 3021; 71% response rate). FINDINGS: Life-time prevalence of DSM-IV alcohol abuse (men: 15.1%; women; 4.5%) was found to be considerably more prevalent than dependence (men: 10.0%; women 2.5%) with few cases among respondents younger than 16 years of age; 12-month prevalence of abuse was 8.4% among men and 2.7% among women and of dependence was 7.3% among men and 2.2% among women. Results show that peak incidence of alcohol disorders occurs at 16-17 years of age and that early initiation into alcohol use is associated with an increasing odds of disorder onset, especially for dependence among women. Exploratory analysis of retrospectively assessed diagnostic stability show: a temporal progression to abuse and then dependence, that nearly half of past abuse diagnoses are in remission, abuse remission is more common than progression to dependence, and dependence is highly persistent, especially among women. CONCLUSIONS: Alcohol disorders are frequent in adolescent and young adults being characterized by transient abuse and less prevalent but persistent dependence syndromes. The relatively high prevalence of dependence diagnoses in this young population wit few years of alcohol use is discussed with regard to the clinical validity of DSM-IV criteria in adolescents and young adults.     

Financial stress, social support, and alcohol involvement: A longitudinal test of the buffering hypothesis in a general population survey.

This study examined whether specific facets of social support (tangible assistance, appraisal and belonging) moderate the relationship between a specific type of stress (financial stress) and alcohol involvement (drinking to cope, heavy drinking, and alcohol problems). Data were derived from a community sample stratified by education and race. Respondents (N?=?1,040) were interviewed in 1986 and 1989 and had drunk alcohol during the year preceding both interviews. Results supported the buffering influence of tangible support on the financial stress–alcohol involvement relationship. In contrast, neither appraisal nor belonging support consistently revealed a buffering pattern. These findings indicate the importance of taking into account specific components of social support when examining the relationship between specific sources of life stress and alcohol involvement.

Temporal progression of alcohol dependence symptoms in the U.S. household population: Results from the National Comorbidity Survey.

General population data are presented on patterns and predictors of temporal progression of alcohol dependence symptoms in the general population. The data come from the National Comorbidity Survey, a nationally representative general population survey of respondents ages 15–54. Lifetime symptom classes were estimated with latent class analysis (LCA). A 4-class LCA solution, including a 1st asymptomatic class and 3 progressively more serious symptomatic classes, was found to fit the data. Probability of initial symptom onset among drinkers was found to be highest in the 10–24 age range, to be higher among men than women, and to have increased dramatically in the past 4 decades. Age, gender, and cohort effects were less powerful in predicting symptom progression. A narrowing of the gender difference over time was due largely to a convergence in initial symptom onset among men and women ages 10–24. These results suggest that a rise in initial problems was more important than an increase in the transition from problems to dependence in accounting for the growing prevalence of alcohol dependence during the post-World War II years in the United States.

Nosological comparisons of DSM-III-R and DSM-IV alcohol abuse and dependence in a clinical facility: comparison with the 1988 National Health Interview Survey results

The purpose of this study was to compare DSM-III-R and proposed formulations of DSM-IV diagnoses of alcohol use disorders in a clinical sample with the same assessment methods used in a large national survey previously reported. Issues included the number of symptoms required for abuse and dependence diagnoses, the effects of requiring evidence of physiological dependence to make the dependence diagnosis (Option 1 vs. Option 2), whether to require a duration criterion, and the concept of alcohol abuse. The diagnostic criteria proposed in the 1991 DSM-IV options book were the criteria investigated in this study. Concordance between DSM-III-R and DSM-IV was closest when the form of DSM-IV used was most similar to DSM-III-R. The duration criterion had much less effect on a dependence diagnosis in this clinical sample than in the general population. DSM-IV Option 2 for alcohol dependence excluded a number of cases from the dependence diagnosis who received such a diagnosis under DSM-III-R and DSM-IV Option 1. Abuse continued to function as a residual category, especially noticeable under increasingly restrictive definitions of dependence, and was rare in both the clinical and general population sample. Implications of the findings for research and other purposes are discussed.     

Prevalence of ICD-10 harmful use of alcohol and alcohol dependence among the rural population in Udmurtia

Aggressive treatment of thoracic malignancy may be complicated by complex defects in the chest wall. These may be associated with serious complications such as chronic infection, respiratory or cardiac failure, or major haemorrhage. Closure of the defect and restoration of the integrity of the chest wall is important for both functional and cosmetic reasons. Local flaps are often used, but may be inadequate or unavailable. Reconstruction with free flaps is better in these cases, as this provides as much abundant well-vascularised tissue as is required. We present 12 patients treated successfully for complex chest wall defects using various forms of local and free flap reconstruction. There were five complications, three healed spontaneously and two required secondary procedures before they healed.     

Hostility, cigarette smoking and alcohol consumption in the general population

Hostility has been associated with coronary heart disease, and hostility may affect coronary risk through its influence on risk factors such as cigarette smoking and alcohol consumption. The objective of this study was to determine relationships between hostile personality, cigarette smoking and alcohol consumption in the general population. The Edinburgh Artery Study comprises a cross-sectional survey of 1592 men and women aged 55-74 years sampled from age-sex registers of 10 general practices throughout the city. The Bedford-Foulds Personality Deviance Questionnaire was used to elicit extrapunitiveness (including hostile thoughts), dominance (including hostile acts) and intropunitiveness. Social class, age and deprivation score were controlled for in multivariate analyses. The hostile thoughts scale emerged as a significant independent predictor of alcohol consumption in men and women (P < or = 0.01), and the models accounted for 4-9% of the variance in alcohol consumption. Hostile acts were independently predictive of smoking in men (P < or = 0.001), with the model accounting for 5% of the variance in smoking. Hostile thoughts were independently predictive of smoking in women (P < or = 0.001), and the model accounted for 4% of the variance in their smoking. We conclude that hostility may affect coronary risk through its influence on lifestyle-related coronary risk factors, although in future further elucidation of hostility type and standard measurement of hostility are necessary.     

Toward an alcohol treatment entry model: a comparison of problem drinkers in the general population and in treatment

Building on a model used in the health services literature, this article examines differences among problem drinkers in treatment and in the general population to understand treatment utilization further. Discriminant function analysis showed significant differences between treated and untreated groups for men and women. For women, lifetime general treatment history, ethnicity, and employment were major contributors to the model; for men, the most important variables were social consequences, treatment history, and employment. For women, only the domain of individual predisposing variables provided a unique contribution to the model (p < 0.01). For men, the individual predisposing (p < 0.001), need (p < 0.001), and enabling (p < 0.01) domains did so. Findings indicate important differences in the factors that influence treatment entry for women and men.     

The latent dimensionality of DIS/DSM-III-R nicotine dependence: exploratory analyses

Decisions on DSM-IV criteria for alcohol dependence were based in part on latent structure analyses of field survey data on alcohol problems. Analogously, to investigate the latent structure of nicotine dependence in an epidemiological sample, we carried out a dichotomous item factor analysis of DSM-III-R symptom data gathered from 394 young adults who reported a history of sustained daily smoking. Smokers and their dependence symptoms were identified by means of the NIMH Diagnostic Interview Schedule version III revised, administered to a random sample of 1007 21-30-year-olds who were members of a health maintenance organization in the Detroit area. Comparing different latent structure models using LISCOMP software with bootstrap re-sampling, followed by multiple logistic regression, we found that a two-factor model indicating a 'general dependence' and a 'failed cessation' dimension best accounted for the observed data. Current smoking status (persistent vs. past smoking) was associated with the two factors independently. Replication and additional research on construct, discriminant and convergent validity are needed.     

Intervention in alcohol use disorder in a general practice

AIM: To report the outcome of intervention in 70 patients with alcohol use disorder in a general practice. METHOD: Of the 84 patients age 18-69 years identified clinically or by a screening programme with alcohol use disorder, 70 who were available for at least 2 year follow up after diagnosis were included in the study group. The clinical notes of these patients were reviewed to determine evidence of sustained achievement of abstinence or controlled drinking and factors contributing to successful change in alcohol use. RESULTS: Sustained abstinence or controlled drinking was verified for 31 patients (44%) with a further 26 patients (37%) reporting reduction in alcohol use without evidence of sustained improvement. The mean interval from diagnosis to sustained improvement was 4 years. Only five patients accepted referral to specialist alcohol units. Successful change in the 31 patients achieving their drinking goal was directly related to intervention at the surgery for 9 patients. CONCLUSION: A motivational approach with focus on the patient's perception of the issues proved relatively successful in this practice. A prolonged period of change was required to achieve drinking goals. Other factors contributing to improvement are discussed.     

A brief survey of the current sexual practices of a population admitted for inpatient treatment of drug dependence

Restenosis remains the main limitation of interventional cardiology. Restenosis occurs when angioplasty-induced intimal hyperplasia as well as arterial remodelling result in flow-limiting renarrowing of the arterial lumen at the angioplasty site. Intimal hyperplasia is an important candidate for gene therapy since it is related to smooth muscle cell proliferation, which is an inviting target for molecular antiproliferative strategies. To date, adenoviral vectors are, by far, the most efficient vectors to perform in vivo arterial gene transfer. These vectors, as well as others, have been recently used to demonstrate that therapeutic genes encoding cytotoxic (herpes virus thymidine kinase) or cytostatic (hypophosphorylatable Rb, Gax, endothelial nitric oxide synthase) products successfully inhibit smooth muscle cell proliferation and related intimal hyperplasia. Despite substantial progress, major technical issues, including the toxicity of first-generation adenoviral vectors, inefficient transduction of atherosclerotic arteries, and the risk of extra-arterial transfection remain to be addressed before gene therapy is applied to clinical restenosis.     

Patterns of density dependence in measles dynamics

An important question in metapopulation dynamics is the influence of external perturbations on the population's long-term dynamic behaviour. In this paper we address the question of how spatiotemporal variations in demographic parameters affect the dynamics of measles populations in England and Wales. Specifically, we use nonparametric statistical methods to analyse how birth rate and population size modulate the negative density dependence between successive epidemics as well as their periodicity. For the observed spatiotemporal data from 60 cities, and for simulated model data, the demographic variables act as bifurcation parameters on the joint density of the trade-off between successive epidemics. For increasing population size, a transition occurs from an irregular unpredictable pattern in small communities towards a regular, predictable endemic pattern in large places. Variations in the birth rate parameter lead to a bifurcation from annual towards biennial cyclicity in both observed data and model data.     

Patterns of use and their relationship to DSM-IV abuse and dependence of alcohol among adolescents and young adults

First use and initiation of regular alcohol use has been frequently found to start in adolescence. However, only few studies have also investigated how many adolescents proceed during ages 14-24 to harmful drinking or even develop alcohol use disorders. This paper - using the EDSP baseline sample of 3,021 community respondents from the Munich area - examines the prevalence of use, abuse and dependence and investigates the dose/disorder relationship. Alcohol abuse was reported by 9.7% of respondents and alcohol dependence by 6.2%. Men were more likely to report an alcohol disorder than women, prevalence also increased in the older age cohorts. However, even among 14- to 17-year-olds a substantial proportion of respondents report high and regular consumption rates, the occurrence of abuse and dependence criteria and even a full dependence syndrome. There is however only a moderate association between average number of standard drinks consumed with the risk of developing abuse and dependence. In light of the substantial rates among adolescents and young adults the validity of DSM-IV alcohol disorder criteria is discussed.     

Chronic debilitating fatigue in Irish general practice: a survey of general practitioners' experience

BACKGROUND: Doctors are called upon to treat chronic debilitating fatigue without the help of a protocol of care. AIMS: To estimate the incidence of chronic debilitating fatigue in Irish general practice, to obtain information on management strategy and outcome, to explore the attitudes of practitioners (GPs) towards the concept of a chronic fatigue syndrome (CFS), and to recruit practitioners to a prospective study of chronic fatigue in primary care. METHOD: A total of 200 names were selected from the database of the Irish College of General Practitioners (ICGP); 164 of these were eligible for the study. RESULTS: Altogether, 118 questionnaires were returned (72%). Ninety-two (78%) responders identified cases of chronic fatigue, giving an estimated 2.1 cases per practice and an incidence of 1 per 1000 population. All social classes were represented, with a male to female ratio of 1:2. Eleven disparate approaches to treatment were advocated. Many (38%) were dissatisfied with the quality of care delivered, and 45% seldom or hardly ever referred cases for specialist opinion. The majority (58%) accepted CFS as a distinct entity, 34% were undecided, and 8% rejected it. Forty-two (35%) GPs volunteered for a prospective study. CONCLUSION: Chronic fatigue is found in Irish general practice among patients of both sexes and all social classes. Doctors differ considerably in their management of patients and are dissatisfied with the quality of care they deliver. Many cases are not referred for specialist opinion. A prospective database is required to accurately assess the scale of this public health problem and to develop a protocol of care.     

Blood pressure survey in a population of newborn infants

Systolic blood pressure in the arm was measured in infants at the ages of 4 to 6 days and 5 to 7 weeks by the Doppler ultrasound technique. At the age of 4 to 6 days the mean blood pressure (+/- SE of mean) in 469 sleeping infants was 70-7 +/- 0-3 mm Hg, rising at 5 to 7 weeks to 89-7 +/- 0-9 mm Hg (in 144 infants). In 252 infants awake at 5 to 7 weeks blood pressure was 96-8 +/- 0-6 mm Hg. In 391 infants in whom measurements were made on both occasions blood pressure at 4 to 6 days was significantly related to blood pressure at 5 to 7 weeks. Thus those infants with relatively high blood pressures at 4 to 6 days showed a weak tendency to have relatively high blood pressures at 5 to 7 weeks. In this trend continues with age it would suggest that the tendency to develop hypertension may already be demonstrable at the age of 4 to 6 days.
