Educational inequalities in hazardous drinking and their associated
mortality in people aged 50 and older in Europe
Background: We examine educational inequalities in hazardous drinking prevalence
among individuals aged 50 or more in 14 European countries, and explore the educational
inequalities in mortality in hazardous drinkers in European regions. Methods: We analyse
data from waves 4, 5 and 6 of the Survey of Health Ageing and Retirement in Europe
(SHARE). We estimated age-standardized hazardous drinking prevalence, and
prevalence ratios (PR) of hazardous drinking by country and educational level using
Poisson regression models with robust variance. We estimated the relative index of
inequality (RII) for mortality among hazardous drinkers and non-hazardous drinkers
using Cox proportional hazards regression models and for each region (North, South, East
and West). Results: In men, educational inequalities in hazardous drinking were not
observed (PRmedium=1.09 [95%CI:0.98-1.21] and PRhigh=0.99 [95%CI:0.88-1.10], ref.
low), while in women they exist, having the highest hazardous drinking prevalence in the
highest educational levels (PRmedium=1.28 [95%CI:1.15-1.42] and PRhigh=1.53
[95%CI:1.36-1.72]). Overall, the Relative Index of Inequality (RII) in all-cause mortality
among hazardous drinkers was 1.14 [95%CI:1.04-1.24] among men and 1.10
[95%CI:0.97-1.25] among women. Educational inequalities among hazardous drinkers
were observed in Eastern Europe for both men (RIIhazardous=1.26 [95%CI:1.05-1.50]) and
women (RIIhazardous=1.47 [95%CI:1.15-1.89]. Conclusions: Higher educational attainment
is positively associated with hazardous drinking prevalence among women, but not
among men in most of the analysed European countries. Clear educational inequalities in
mortality among hazardous drinkers were only observed in Eastern Europe. Further
research on the associations between alcohol use and inequalities in all-cause mortality
in different regions is needed.

Introduction
Socioeconomic position (SEP) refers to the social and economic factors that
influence the position individuals or groups hold within the structure of a society, such as
educational level, income or wealth. Socioeconomic inequalities in health reflect
differences in opportunities for maintaining good health between people with different
SEP.1,2 Several studies in Europe have analysed the relationship between socioeconomic
position and alcohol consumption, but the results found are not consistent.3,4 This
relationship depends on several variables such as country, age, gender,5–8 as well as on
the different ways of measuring alcohol use in a population (e.g. binge drinking,
hazardous drinking), given that their prevalence may vary among socioeconomic
groups.5,9
The health complications related to alcohol consumption are associated with the
socioeconomic position. That is, most of the previous research found worse morbidity
and mortality indicators among the groups with disadvantaged SEP.10–13 Therefore,
alcohol is an important contributor to all-cause mortality inequalities, as it has been
recently shown in a recent publication using data from Nordic countries.14 Additionally,
inequalities in alcohol-related harm could be age-specific as overall alcohol consumption
and drinking patterns have been changing across generations in most European
countries.15
Alcohol use and ageing is an issue of growing relevance for public health in
European societies16,17 as European societies are ageing rapidly. In this context, middle
and older generations play a central role in society. In Europe, both the hazardous
drinking prevalence among population aged 50+ (one in five people) and total mortality
attributable to alcohol are high and with important differences between countries.5,18
Furthermore, middle and old age groups have the highest alcohol-related mortality rates
and therefore the highest number of death losses due to alcohol.19,20
Despite this clear growing evidence on the importance of alcohol use and their
consequences at older ages, previous studies on the topic mostly focused on the adult
population, and did not distinguish the older population.8,11–13,21 The studies focusing on
alcohol consumption among middle and older aged individuals neither focused on
2
interpreting the results on differences in alcohol consumption by socioeconomic status
nor analysed mortality follow-up.5,6,22–24
We examine educational inequalities in hazardous drinking among individuals
aged 50 or more in 14 European countries, and explore educational inequalities in all-
cause mortality by hazardous drinking status in European regions.
Methods
We used cross-sectional and longitudinal data from individuals aged 50-85 from
the Survey of Health, Ageing and Retirement in Europe (SHARE)25,26 for 14 countries
(Austria, Belgium, Czech Republic, Denmark, Estonia, France, Germany, Italy,
Luxembourg, the Netherlands, Slovenia, Spain, Sweden, Switzerland). For the cross-
sectional analysis we used data from wave 5, except for the Netherlands where we used
data from wave 4 as data for wave 5 were unavailable. For the longitudinal analysis we
used data from waves 4 (2011) and 5 (2013), with around 2-year mortality follow-up
(measured in months and reported by a relative in waves 5 (2013) and 6 (2015),
respectively). All countries obtained a probabilistic sample, although the sample design
differed slightly between countries. Country-specific data were clustered into European
regions according to drinking cultures: North (Sweden and Denmark); West (Austria,
Belgium, Germany, Luxembourg, the Netherlands and Switzerland), South (France, Italy
and Spain) and East (Czech Republic, Estonia and Slovenia), as previously done23. The
final sample size for the cross-sectional sample was 26,314 men and 32,239 women.
The outcome variable was hazardous drinking, which is generally defined as
“quantity or pattern of alcohol consumption that places patients at risk for adverse health
events”.27 Hazardous drinking was estimated using three questions of the SHARE
questionnaire adapted to the Alcohol Use Disorders Identification Test, Consumption
(AUDIT-C) and related to frequency and quantity of alcohol consumption as well as binge
drinking,28 as previously done (see 22 for further detail). Men and women who scored ≥5
and ≥4 points, respectively, were classified as hazardous drinkers.28
Educational level, age, country of residence, and self-perceived health (excellent,
very good or good, fair or poor) were the independent variables. Educational level was
3
based on the highest educational degree obtained and reclassified into the International
Standard Classification of Education (ISCED) of 1997, and it was categorised as follows:
low (ISCED 1-2), medium (ISCED 3-4) or high (ISCED 5-6).
Analysis
All analyses were carried out separately for men and women. The sample
distribution was calculated for each variable. We estimated age-standardized (direct
method) hazardous drinking prevalence by country for each educational level and their
corresponding 95% confidence interval (95%CI) using as standard the European
population from the 2011 census from Eurostat. Subsequently, we fit several sex- and
country-specific Poisson regression models with robust variance to obtain prevalence
ratios (PR) of hazardous drinking29 by educational level, adjusting for age and self-
reported health and using the cross-sectional standard weights provided by SHARE.
For the mortality analyses, we used the European region-specific longitudinal
sample, and we combined the medium and high educational level categories to increase
the size of our sample. Finally, to examine educational inequalities in mortality among
hazardous drinkers or non-hazardous drinkers, we used the relative index of inequality
(RII), which considers all educational groups and assumes a linear relationship between
educational level and mortality. The RII is the ratio between mortality at the lowest
educational group as compared with the highest educational group and it was estimated
applying Cox regression models30 adjusting by age, country of residence and self-reported
health. All data preparation and statistical analyses were performed in R 3.5.1 in R Studio
1.1.463.
Results
A description of the characteristics of the cross-sectional data by sex are presented
in Table 1. Of the total number of participants, 45% were men, 70% were >60 years, 61%
had completed at least a medium or high educational degree (ISCED-1997) and 22% were
hazardous drinkers, and roughly three out of four reported good or excellent health. Table
2 presents a description of the characteristics of the longitudinal data. We observed 1,476
deaths in 69,926 person-years at risk among men, and 1,036 deaths in 89,106 person-
4
years at risk among women. The crude mortality rates were 21.1 per 1,000-person years
in men and 11.6 per 1,000-person years in women. Details on the distribution of the data
by region and sex are presented in Table 2.
The hazardous drinking prevalence at ages 50-85 (average of the 14 European
countries studied) was for men 22.3% (95%CI 21.3-23.3) among the low educated group,
27.3% (26.3-28.4) among the middle educated group and 24.8% (23.6-25.9) among the
highest educated group (Table 3). This resulted in inexistent educational inequalities in
hazardous drinking among men (PRmedium= 1.09 [95%CI: 0.98-1.21] and PRhigh=0.99
[95%CI: 0.88-1.10], ref. low). For women, hazardous drinking prevalence were 15.8%
(15.1-16.5), 19.3% (18.5-20.1) and 25.1% (23.6-25.9) for the lowest, middle and highest
educated group, respectively. Overall, inequalities in hazardous drinking were found
among women with middle and higher educated groups showing higher hazardous
drinking prevalence as compared to those with low education (PRmedium= 1.28 [95%CI:
1.15-1.42] and PRhigh=1.53 [95%CI: 1.36-1.72]).
The hazardous drinking prevalence was heterogeneous across the countries and
educational levels. Among men, it ranged from 11.5% (95% CI: 8.5-14.5%) among
higher educated Swedish to 48.3% (43.3-53.3%) among higher educated Danish. Among
women, it ranged from 5.3% (4.2-6.3%) among middle educated Estonians to 46.5%
(42.1-50.9%) among higher educated Danish. Among men, higher hazardous drinking
prevalence among middle and higher educated groups were observed in Denmark,
Luxembourg (only higher educated group) and France (only middle educated group), and
lower prevalence among highest educated group was observed in Estonia. Among
women, country-specific results followed the overall result of higher hazardous drinking
prevalence among middle and higher educated groups, except in Eastern Europe, Italy
and the Netherlands were educational inequalities in hazardous drinking prevalence were
not observed.
5
In terms of mortality, educational inequalities in total mortality were observed in
the pooled European sample, irrespective of the hazardous drinking condition (see Figure
1). Overall, for men the relative index of inequality (RII) were 1.14 [95%CI: 1.04-1.24]
among hazardous drinkers and 1.16 [95%CI: 1.12-1.20] among non-hazardous drinkers,
while for women these results were RII=1.10 [95%CI: 0.97-1.25] and RII=1.09 [95%CI:
1.03-1.14], respectively. Educational inequalities in mortality among hazardous drinkers
were observed in Eastern Europe for both men (RIIhazardous=1.26 [95%CI: 1.05-1.50]) and
women (RIIhazardous=1.47 [95%CI: 1.15-1.89]). These inequalities were also observed in
Southern Europe, but were not statistically significant, for both men (RIIhazardous=1.17
[95%CI: 0.94-1.47]) and women (RIIhazardous=1.22 [95%CI: 0.95-1.55]), and they were
not observed in Western and Northern Europe.
Discussion
In this study we examined educational inequalities in hazardous drinking and in
mortality among hazardous drinkers among Europeans aged 50 years old or over. The
two main findings of this study are: (1) Educational inequalities in the hazardous drinking
prevalence –higher hazardous drinking among those with high levels of education- were
found in women but not in men, with some country-specific exceptions; and (2)
educational inequalities in all-cause mortality among hazardous drinkers (for both men
and women) were found in Eastern Europe, but not in Southern, Northern and Western
Europe.
Before discussing our results further, we would like to highlight some of the
strengths and limitations of our study. The first phase of this study was carried out using
a large representative sample of the European population aged 50 to 85 years old, and in
the second phase we used a longitudinal study. As typically done in previous studies, the
hazardous drinking prevalence was estimated based on self-reported data. We adapted
the SHARE questions to the AUDIT-C test, which has been validated and is widely used
to detect hazardous drinkers,31 as previously used in several scientific
publications.5,6,9,22,29,32 The small sample size for the longitudinal study (mortality) has
not allowed us to obtain results by country, and for this reason region-specific results
6
were presented. A common limitation in any longitudinal study is the loss at follow-up
(or attrition). In our case, because of the relatively short follow-up time/period (around 2
years) we could follow >75% of the cases, either survey follow-up or mortality follow-
up (end-of life interview with a proxy-resident). In addition, as most health surveys, the
SHARE sample is selected. Nonetheless, a comparison of SHARE mortality data with
mortality register data suggests SHARE mortality to be slightly lower than population
level mortality.33 All in all, as for the mortality analysis these results are to our knowledge
the first attempt to study the associations between hazardous drinking and all-cause
mortality among the population aged 50 years old and over in a cross-region comparison
in Europe. However, we acknowledge that our mortality results are not necessarily
reflecting population level mortality dynamics and should be taken cautiously because of
the attrition and relatively small sample size.
This study used a sample of middle aged and old European, whereas previous pan-
European studies focusing on socioeconomic differences in alcohol consumption
frequently used samples of adults (aged 25 years and over, with different cut off ages),
different alcohol consumption measures and presented mixed results.3,4 Our results
showing higher educational attainment to be positively associated with higher hazardous
drinking prevalence among women and not among men are consistent with previous
research using adult ages sample.3 Our results for men on the lack of educational
inequalities in hazardous drinking contrast with earlier findings based on data from the
early 2000s, which found that higher individual socioeconomic position was positively
associated with alcohol drinking status 4. These differences seem explained by differences
between the studies in both the age groups included and the alcohol use definition.
Our findings on a clear distribution of hazardous drinking by educational level
among women but not among men may be explained, as happened with tobacco, by the
theory of diffusion of innovations.34 According with this perspective, alcohol use in the
population may have started in men with higher educational level, expanding later to men
with lower educational level, afterwards to women with higher educational level and,
finally, to those women with lower educational level.35 This explanation is in line with a
comparison between our results and previous research among working age adults from
the late 1990s which found higher binge drinking prevalence among men from high SEP
as compared to their lower SEP counterparts.36 Thus, it seems to indicate that hazardous
7
drinking has spread out across all SEP groups among men. This theory seems also to
apply to women as the increase in alcohol consumption among women seems to have
occurred first in populations with high levels of women’s labour force participation and
high gender equality.4,6 In line with that, we would be in a stage that women from low
socioeconomic status could be expected to increase their hazardous drinking prevalence
as a consequence of women’s empowerment.6 Evidence from younger cohorts suggest
that the relationship between socioeconomic position and alcohol consumption has
changed, as for example family SEP has not been associated with adolescents alcohol
consumption.7
Country-specific results are interesting but also more difficult to be compared with
previous research as SEP differences in hazardous drinking have rarely been analysed
among older European populations. For men, the country-specific exceptions were found
in Denmark and in Luxembourg, where those with higher education had higher hazardous
drinking prevalence. In Denmark, our results contrast with a no association between
socioeconomic position and risky single occasion drinking in a sample of adults aged 15
to 79,37 and therefore this suggests that the inequalities we observed may be driven by
quantity of alcohol consumption and not by patterns of drinking. In contrast, in Estonia
our findings were in the opposite direction, as men with higher educational attainment
had low hazardous drinking prevalence, which could be related to the rapid societal
changes experienced in Estonia in the 1990s and early 2000s.38
For women, inequalities in hazardous drinking were not observed in Eastern
Europe, where hazardous drinking prevalence was typically low across all educational
levels, especially among the generations analysed in this study. Therefore, it seems
plausible to think that women born in the 1930-50s in Eastern Europe had not widely
adopted men’s unhealthy lifestyles such as alcohol consumption. The other observed
exceptions among women on no inequalities in hazardous drinking were found in the
Netherlands and in Italy. It seems possible that these results for the Netherlands are related
to a diffusion of hazardous drinking also among women with low educational level as
they presented a considerably high prevalence as compared with low educated women in
other countries. Thus, Dutch women seem to be in and advanced staged in the theory of
diffusion of innovation as regards to alcohol use.
8
Regarding educational inequalities in all-cause mortality among hazardous
drinkers we found clear educational inequalities in Eastern Europe. This is in line with
previous research highlighting the fact that 1) Eastern European countries have higher
educational inequalities in all-cause mortality;39 and that 2) the riskier drinking patterns
are typically observed in Eastern Europe,40 which are particularly influenced by
socioeconomic position and lead to higher inequalities in alcohol-attributable mortality
as compared to other European countries.11
For the rest of the regions the results are somewhat less clear as we did not find
educational inequalities in all-cause mortality in the hazardous drinking group. This is
somewhat difficult to be compared with previous research, but it contrasts with previous
literature that found important socioeconomic inequalities in alcohol-attributable causes
of death.11 Therefore, the fact that we did not find inequalities in all-cause mortality
among hazardous drinkers does not necessarily imply that they do not exist. This is to our
knowledge the first time that socioeconomic inequalities in all-cause mortality are being
analysed in individuals with hazardous alcohol use. The SHARE data that we used
allowed us to provide some regional insights, but at the same time, we should recognise
the rather low sample size as compared with mortality register datasets available mostly
for Nordic countries. It could also be that inequalities in alcohol-attributable mortality are
related to specific dimensions of alcohol use, such as the pattern of consumption.
Our results have strong implications for public health policy makers as the
hazardous drinking prevalence at ages 50 years old and over in Europe is notably high
and SEP inequalities in alcohol consumption exist among women. Reducing both overall
alcohol consumption levels and SEP inequalities, especially among women, should be
prioritised for preventive public health policymakers in most European countries. Future
research should assess whether our results persist over time and explore the mechanisms
that underlie potentially decreasing trends in both alcohol consumption levels and SEP
inequalities. Additional research on the impact of alcohol consumption on inequalities in
all-cause mortality should be also further explored with larger cohort studies, as most of
the previous research on the topic mostly focused exclusively on causes wholly-
attributable to alcohol14 and not in other causes alcohol is indirectly associated with.
9
Conclusions
In sum, the hazardous drinking prevalence among individuals aged 50 years and
over is high in most countries in Europe. Our results suggested important educational
differences in hazardous drinking among Europeans aged 50-85 for women –those with
higher educational level tend to engage more in hazardous drinking-, but not for men,
with few country-specific exceptions discussed above. These results call for a need of
public health policies in order to reduce the elevated hazardous drinking prevalence and
reduce their SEP inequalities. Finally, our results suggest educational differences in all-
cause mortality do not depend on the hazardous drinking sample, except in Eastern
Europe. Further investigations should contrast these results as well as study the extent to
which different dimensions of alcohol use have an impact on educational inequalities in
all-cause mortality in European regions.
