AimTo estimate the prevalence of hazardous drinking and its socio-economic distribution among Russian men. Design Participants were an age-stratified, population-based random sample of men aged 25-54 years living in Izhevsk, a city in the Urals, Russia. Interviewers administered questionnaires to cohabiting proxy respondents about behavioural indicators of hazardous drinking derived from frequency of hangover, frequency of drinking beverage spirits, episodes in the last year of extended periods of drunkenness during which the participant withdraws from normal life (zapoi), consumption of alcoholic substances not intended to be drunk (surrogates) and socio-economic position. Logistic regression was used to examine associations between socio-economic position and indicators of hazardous drinking in the past year. Findings Of 1750 men, 79% drank spirits and 8% drank surrogates at least sometimes in the past year; 25% drank spirits and 4% drank surrogates at least weekly and 10% had had an episode of zapoi in the past year. After adjustment for other socio-economic factors, education was strongly associated with indicators of hazardous drinking. Men with the lowest level of education compared to the highest level of education had an odds ratio of surrogate drinking of 7.7 (95% CI 3.2-18.5), of zapoi of 5.2 (2.3-11.8) and of frequent hangover of 3.7 (1.8-7.4). These indicators of hazardous drinking were also independently strongly associated with being unemployed (versus employed) and with levels of household wealth/amenities. Associations of all these variables with daily consumption of beverage spirits were weaker. Conclusion Using a novel range of indicator variables of hazardous drinking, this paper shows that the prevalence of these behaviours is high among working-age men in this Russian city. Moreover, these hazardous behaviours show very clear socio-economic patterns, with particularly high prevalence among those who have had the least education and are not in employment. In contrast, more conventional measures of heavy drinking, based on frequency of consumption of beverage spirits, are less prevalent and show much weaker associations with socio-economic position.
Abstract. Andreev E, Koopman M, Arisz L (Medical University-Sofia, Sofia, Bulgaria and University of Amsterdam, Amsterdam, The Netherlands). A rise in plasma creatinine that is not a sign of renal failure: which drugs can be responsible? (Review.) J Intern Med 1999; 246: 247±252. This is a review of the available information about drugs which cause an increase in plasma creatinine concentration without decreasing glomerular filtration rate (GFR). The GFR is the main, but not the single, determinant of the plasma creatinine levels. Several drugs, such as cimetidine, trimethoprim, corticosteroids, pyrimethamine, phenacemide, salicylates and active vitamin D metabolites, have been reported to increase plasma creatinine without influencing its glomerular filtration. Cimetidine, trimethoprim, pyrimethamine and salicylates can inhibit secretion of creatinine by the proximal tubule. Corticosteroids and vitamin D metabolites probably modify the production rate and the release of creatinine. The exact mechanism of phenacemide±creatinine interaction is not fully explained. These drug-induced alterations in plasma creatinine concentration have clinical significance when GFR is estimated by using plasma creatinine.
Background There is a consensus that the large fluctuations in mortality seen in Russia in the past two decades can be attributed to trends in alcohol consumption. However, the precise mechanisms linking alcohol to mortality from circulatory disease remain unclear. It has recently been argued that a substantial number of such deaths currently ascribed to cardiovascular disorders are misclassified cases of acute alcohol poisoning.Methods Analysis of routine mortality data and of a case–control study of mortality among working-age (25–54 years) men occurring in the Russian city of Izhevsk, west of the Ural mountains, 2003–05. Interviews were carried out with proxy informants for both the dead cases (N = 1750) and the controls (N = 1750) selected at random from a population register. Mortality was analysed according to indicators of alcohol problems.Results Hazardous drinking was associated with an increased risk of death from circulatory diseases as a whole [odds ratio (OR) = 4.14, 95% confidence interval (CI) 3.23, 5.31] adjusted for age, smoking and education. The association with alcoholic cardiomyopathy was particularly strong (OR = 15.7, 95% CI 9.5, 25.9). Although there was no association with deaths from myocardial infarction (MI; OR = 1.17, 95% CI 0.59, 2.32), there was a strong association with the aggregate of all other ischaemic heart disease (IHD; OR = 4.04, 95% CI 2.79, 5.84). Stronger associations for each of these causes (other than MI) were seen with whether or not the man had drunk very heavily in the previous week. However, associations also remained when analyses were restricted to subjects with no evidence of recent heavy drinking, suggesting that misclassification of acute alcohol poisonings is unlikely to explain these overall associations.Conclusion Taken as a whole, the available evidence suggests that the positive association of alcohol with increased cardiovascular disease mortality may be best explained as being the result of a combination of chronic and acute alcohol consumption resulting in alcohol-related cardiac disorders, especially cardiomyopathy, rather than being due to misclassification of acute alcohol poisoning. Further work is required to understand the mechanisms underlying the link between heavy alcohol consumption and deaths classified as being due to IHD (other than MI).
