INTRODUCTION: In recent years, beverage composition of total alcohol consumption has changed substantially in Sweden. As beverage choice is strongly associated with drinking practices, our paper aims to analyse trends in beverage composition of alcohol consumption by age, period and cohort. METHODS: Age-period-cohort (APC) analysis was conducted using monthly data from the Swedish Alcohol Monitoring Survey (2003-2018). The sample consisted of n = 260 633 respondents aged 16-80 years. APC analysis was conducted on drinkers only (n = 193 954; 96 211 males, 97 743 females). Beverage composition was defined as the beverage-specific proportion of total intake in litre ethanol. Fractional multinomial logit regression was applied to estimate the independent effects of age, period and cohort on trends in beverage composition. RESULTS: Regression models revealed statistically significant effects of age on all beverages except for medium-strength beer and spirits in males. Controlling for age and cohort, decreasing trends were found over time for medium-strength beer and spirits. The proportion of regular beer increased statistically significantly in males and the proportion of wine in females, whereas the trends for the opposite sex remained stable in each case. Predictions for cohorts showed statistically significant decreasing trends for medium-strength beer in males, lower proportions for regular beer and higher proportions for spirits in the youngest cohorts. DISCUSSION AND CONCLUSIONS: The increasing proportion of wine drinking, which is associated with less risky drinking practices, may decrease alcohol-related morbidity and mortality. Increasing proportions of spirits in the youngest cohorts raises concerns of a possible revival in spirits consumption among the youngest.

Background and aims: Cancer has emerged as the leading cause of death in human populations. The contribution of alcohol has been highly suspected. The purpose of this paper was to analyze the time trend of digestive cancers in Romania, in terms of mortality rates (1955-2012), and incidence rates (2008-2012), and the alcohol consumption data (1961-2010), aiming to find out if there is any association.

Methods: The data on six more common digestive cancers mortality rates (1955-2012) and incidence rates (2008-2012) were obtained from the historical and recent country statistics and publications of International Agency for Research on Cancer (IARC)/World Health Organisation (WHO), as age-standardized rate expressed per 100,000 population (ASRw). Data on alcohol consumption were obtained from the statistics and publications of WHO and United European Gastroenterology (UEG), as liters of pure alcohol/year. Results: Between 1955-2012, the ASRw of mortality registered an increase of the cancers of the esophagus in M (from 2.03 to 3.90), and of colorectal cancer in both sexes (from 4.65 to 18.20 in M, and from 4.57 to 9.70 in F). Between 1980-2012, an increasing trend of mortality was registered, in both sexes, for the cancers of the pancreas (from 5.50 to 9.30 in M and from 2.92 to 5.10 in F) and liver (from 1.77 to 11.00, in M, and from 0.83 to 4.20 in F). In terms of incidence, between 2008-20012, an increasing trend of ASRw was registered for the cancers of the esophagus in M (from 3.90 to 4.30), gastric cancer in M (from 15.90 to 16.30), colorectal cancer in both sexes (from 27.60 to 34.50 in M and from 19.00 to 20.20 in F), pancreatic cancer in F (form 5.20 to 5.90), and liver cancer in M (from 8.10 to 9.20). Alcohol consumption per capita (liters pure alcohol/year) increased in the same period, from an average of 5 in 1961, to 12.8 in 2003-2005, and to 14.4 in 2008-2010.

Conclusions: Given the parallel increase of some digestive cancers and alcohol consumption registered in our area, alcohol could represent more than a coincidence.

Alcohol has consistently been shown to increase breast cancer (BC) risk. This association may be modified by single nucleotide polymorphisms in alcohol dehydrogenase isoenzymes ADH1B and ADH1C. The Netherlands Cohort Study comprises 62 573 women, aged 55-69 years at baseline (1986). Follow-up for postmenopausal BC for 20.3 years was available. Genotyping of 6 tag SNPs in ADH1B and ADH1C, respectively, was performed on DNA from toenails. A case-cohort approach was used for analysis (complete data available for: nsubcohort= 1301; ncases= 1630). Cox regression models for postmenopausal BC were applied to determine marginal effects of alcohol intake and SNPs using a dominant genetic model, as well as multiplicative interaction of the two. Results were also obtained for subtypes by estrogen (ER) and progesterone receptor (PR) status. Multiple testing was adjusted for by applying the false discovery rate (FDR). Alcohol intake (categorical) increased the risk of postmenopausal BC (ptrend=0.031). Trends for ER and PR subgroups followed a similar pattern. Continuous modelling of alcohol resulted in a hazard rate ratio (HR) for overall postmenopausal BC of 1.09 (95% CI: 1.01 - 1.19) per 10g/d of alcohol. SNPs were not associated with BC risk. No effect modification of the alcohol-BC association by SNP genotype was seen after FDR-correction in overall BC and ER/PR subgroups. In conclusion, alcohol was shown to increase the risk of postmenopausal BC. This association was not significantly modified by common ADH1B and ADH1C SNPs, neither in overall BC nor in hormone receptor defined subtypes.
