    Effects of beverage alcohol price and tax levels on drinking: a meta-analysis of 1003 estimates from 112 studies

    ADDICTION, Issue 2 2009
    Alexander C. Wagenaar
    ABSTRACT Aims We conducted a systematic review of studies examining relationships between measures of beverage alcohol tax or price levels and alcohol sales or self-reported drinking. A total of 112 studies of alcohol tax or price effects were found, containing1003 estimates of the tax/price,consumption relationship. Design Studies included analyses of alternative outcome measures, varying subgroups of the population, several statistical models, and using different units of analysis. Multiple estimates were coded from each study, along with numerous study characteristics. Using reported estimates, standard errors, t -ratios, sample sizes and other statistics, we calculated the partial correlation for the relationship between alcohol price or tax and sales or drinking measures for each major model or subgroup reported within each study. Random-effects models were used to combine studies for inverse variance weighted overall estimates of the magnitude and significance of the relationship between alcohol tax/price and drinking. Findings Simple means of reported elasticities are ,0.46 for beer, ,0.69 for wine and ,0.80 for spirits. Meta-analytical results document the highly significant relationships (P < 0.001) between alcohol tax or price measures and indices of sales or consumption of alcohol (aggregate-level r = ,0.17 for beer, ,0.30 for wine, ,0.29 for spirits and ,0.44 for total alcohol). Price/tax also affects heavy drinking significantly (mean reported elasticity = ,0.28, individual-level r = ,0.01, P < 0.01), but the magnitude of effect is smaller than effects on overall drinking. Conclusions A large literature establishes that beverage alcohol prices and taxes are related inversely to drinking. Effects are large compared to other prevention policies and programs. Public policies that raise prices of alcohol are an effective means to reduce drinking. [source]

    Variation in essential oil composition of rose-scented geranium (Pelargonium sp.) distilled by different distillation techniques,

    Abstract The rose-scented geranium (Pelargonium sp.) cultivar ,Kelkar', grown in the agroclimatic conditions of the western Himalayas, was processed by various hydrodistillation methods, which revealed that water distillation of the herb gave a higher oil yield (0.16,0.22%) than the water,steam distillation (0.09,0.12%) and steam distillation methods (0.06,0.18%). The samples were analysed by GC and GC,MS to study and compare the essential oil compositions which revealed that the oil distilled by the water,steam distillation method contained a higher content of monoterpene hydrocarbons (1.7%), followed by steam distillation without cohobation and without recycling (1.5%). A higher content of sesquiterpene hydrocarbons (4.4%) was found in cumulative oil followed by ,direct oil' (4.2%) obtained by steam distillation with cohobation and without recycling of hydrosol, followed by the water,steam distillation method (3.4%). ,Decanted oil', recovered from redistilling the hydrosol obtained by steam distillation with cohobation and without recycling, contained maximum monoterpene cyclic ethers (1.1%) and carbonyl content (9.9%), closely followed by water,steam distillation method (1.1% and 7.2%, respectively). Steam distillation without cohobation and without recycling of hydrosol yielded essential oil with a higher percentage of esters (21.1%), followed by ,direct oil' (16.6%). Lower ester content (5.3%) was noticed in ,decanted oil', followed by oil distilled by steam distillation with cohobation and with recycling (11.8%) and oil distilled in a Clevenger apparatus by the water distillation method (12.2%), whereas maximum total alcohols were found in the ,decanted oil' (75.1%), followed by oil from the Clevenger apparatus (72.8%) and steam distillation with cohobation and with recycling (69.1%). A lower alcohol content was found in the ,direct oil' (55.2%) closely followed by ,cumulative oil' (55.8%). The variation in total alcohol and ester contents in geranium oil samples, distilled by using different processing techniques on pilot scale distillation, is mainly due to hydrolysis of some volatile constituents. This was further supported by acid values of the oils, along with other physicochemical properties, such as speci,c gravity, optical rotation, refractive index, solubility in alcohol, ester value with cold and hot methods, estimation of ester content as geranyl formate and geranyl tiglate, ester number after acetylation, and ester number after formylation with aceto-formic acid and formic acid. Methods have been standardized and proposed for distillations of speci,c quality, e.g. ester-rich and alcohol-rich geranium oils, to meet different requirements of the industry.

    Alcoholic beverage consumption and gastric cancer risk: A prospective population-based study in women

    INTERNATIONAL JOURNAL OF CANCER, Issue 2 2007
    Susanna C. Larsson
    Abstract The association between alcohol consumption and risk of gastric cancer remains controversial. Moreover, prospective data on the role of alcoholic beverage type are sparse. We prospectively investigated the association between total alcohol (ethanol) intake as well as specific alcoholic beverages and risk of gastric cancer in the Swedish Mammography Cohort, a population-based cohort of 61,433 women. Alcohol intake and other dietary exposures were assessed at baseline (1987,1990) and again in 1997 using a food-frequency questionnaire. Incident gastric cancer cases were ascertained through the Swedish Cancer Register. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During 966,807 person-years of follow-up, through June 2005, 160 incident cases of gastric cancer occurred. Total alcohol intake was not significantly associated with risk of gastric cancer. Compared with nondrinkers, the multivariate HR of gastric cancer for women with an alcohol intake of 40 g or more per week was 1.33 (95% CI, 0.79,2.25). Consumption of medium-strong/strong beer was associated with a statistically significant increased risk of gastric cancer; the multivariate HR for women who consumed more than one serving of medium-strong/strong beer per week (median, 2.5 drinks/week) was 2.09 (95% CI, 1.11,3.93; p -trend = 0.02) compared with no consumption. Consumption of light beer, wine, and hard liquor was not significantly associated with gastric cancer risk. Our findings suggest that constituents of beer other than alcohol may be associated with an increased risk of gastric cancer. © 2006 Wiley-Liss, Inc. [source]
