Drinking and acquisition of unrecorded alcohol across educational groups in Sweden.

Abstract

It is estimated that 18.5% of total alcohol consumption in Sweden in 2018 was unrecorded. However, little is known about the socio-economic profile of consumers of unrecorded alcohol. The aim of this study was to elucidate this issue by analysing data from a unique Swedish national repeated cross-sectional alcohol use survey. Individual-level information on alcohol consumption and socio-economic status (SES) for the years 2013-2018 was retrieved from the Monitoring Project; a nationally representative monthly alcohol use survey. The analytical sample comprised 64 375 respondents aged 25-74 years. SES was measured by educational level. We used three educational groups: (i) low (<10 years); (ii) intermediate (10-12 years); and (iii) high (13+ years). We included indicators of the following sources of unrecorded alcohol consumption: travellers' import, smuggled alcohol, home production, internet and illicit home-distilling. We estimated adjusted SES-specific means of the various forms of unrecorded consumption. The means were adjusted for the effects of age, sex and region. There were no significant educational differences in the total of unrecorded alcohol consumption; the same holds true for home-production and internet. However, with respect to smuggled and home-distilling, a statistically significant educational gradient was observed with the lowest educational group scoring approximately four times higher than the highest. Our findings suggest that there are no differences across educational groups in the consumption of unrecorded alcohol as a whole. However, consumption of smuggled alcohol and illicitly distilled spirits is elevated in the low educational group.
