Abstract
Objectives To explore current alcohol drinking patterns, behaviours and attitudes in Great Britain.
Design and setting Independent online cross-sectional survey.
Patients and interventions Survey of 2221 individuals from a representative panel.
Main outcome measures and results Excessive alcohol consumption is a widespread problem across Great Britain. Binge-drinking is common among 18–24 year olds, with 19% reporting drinking 10+ drinks on the same drinking day. ‘Pre-loading’ with alcohol at home before going out was reported by 30% of 18–24-year-old drinkers, of whom 36% get drunk twice or more a month, with 27% having injured themselves while drunk. Among older drinkers, 25% regularly drink to excess, 8% drink seven or more drinks on a typical drinking day and 9% self-reported drink-driving. Male gender was an independent risk factor for heavy (>40 units/week) alcohol abuse (odds ratio 3.05 (95% CI 1.82 to 5.10)). Men (19%) were more likely than women (8%, p<0.001) to report binge-drinking, drink-driving (11% vs 3%, p<0.001), or to have missed work owing to alcohol consumption (12% vs 7%, p<0.001). Young drinkers said they were heavily influenced by overall alcohol price and drink promotions. Increasing average weekly alcohol consumption, age <55 years, male gender, never having been married and being in full-time employment were all independently associated with a history of alcohol-related self-harm. Alcohol abuse was not related to socioeconomic status.
Conclusions Alcohol abuse remains common across all socioeconomic strata and geographical areas of Great Britain. Minimum pricing strategies and interventions that target cheap on-trade alcohol products seem likely to bring major public health benefits.

Introduction
Current UK government guidelines recommend that men should not regularly drink more than 3–4 units of alcohol a day and women should not regularly drink more than 2–3 units of alcohol a day.1 Despite recent short-term falls in alcohol consumption the prevalence of hazardous drinking (>21/14 units/week for men/women, respectively) remains high, with 25% of men and 18% of women drinking at or above these weekly levels.2 Alcohol abuse is directly associated with cirrhosis, epilepsy, pancreatitis, dementia and foetal abnormalities and contributes to a wide range of chronic conditions, including coronary artery disease, stroke and many cancers such as oesophagus, colon, breast and liver.3 Alcohol intoxication is associated with harm from acute events such as road traffic accidents, fires, drowning, assault and child abuse. The direct burden of alcohol-related ill health in the United Kingdom is estimated to cost the National Health Service £3.0 billion/year (2006–7 prices),4 while the total costs of alcohol abuse in England (including personal loss of income and other human costs, costs to employers and public service costs) have been estimated at £55.1 billion/year.5
Information on alcohol consumption is currently collated from people living in private households in Great Britain as part of the General Lifestyle Survey (GLS), an annual survey which includes questions on the average weekly alcohol consumption and maximum amount drunk on any 1 day during the previous 7 days.6 However, the GLS does not explore any of the deleterious effects of alcohol abuse upon wider society such as violence, accidents, or loss of workplace productivity. The British Society of Gastroenterology (BSG) therefore commissioned an independent survey of drinking behaviours and attitudes among the general public with the aims of examining the prevalence and detrimental social effects of alcohol abuse and exploring predictive factors for excessive alcohol consumption and subsequent personal injury.
Methods
This was a cross-sectional online survey commissioned by the BSG and administered by YouGov plc from a representative panel of 300 000+ individuals who had previously agreed to take part in surveys. An email was sent to panellists selected at random from the survey panel, inviting them to take part in the survey and providing a link to the survey. The responding sample of 2221 (48% male) adults aged ≥18, was weighted to the Great British population to provide a representative reporting sample. The voluntary survey was anonymous and was conducted during 6–8 December 2010. Associations between categorical variables were analysed by χ2 tests, with a p value of <0.05 considered statistically significant. Stepwise multivariate logistic regression was used to determine predictive factors for excess alcohol consumption and subsequent alcohol-related self-harm. Only variables with a univariate p<0.10 were included in the multivariate analysis.
Results
Pervasive impact of alcohol excess across Great Britain
The demographics and overall drinking habits of the study population are outlined in table 1. Overall, 86% of respondents drank alcohol, with 52% drinking at least once a week and 15% drinking four times a week or more. It was common for people to drink at least weekly (48–53%) throughout Great Britain, with no significant regional variations. London had a greater proportion of non-drinkers (19%) than the rest of Great Britain (12%, χ2=9.3, p=0.004). Excessive drinking (at least four drinks/day) on drinking days was commonest in Wales (48%) and Scotland (46%), compared with 39% in England. The North East of England recorded the highest proportion of heavy daily drinkers (53%), compared with 41% in the Midlands, 38% in London and 31% in the East of England. Similar findings were noted when drinkers were asked how frequently they became drunk; becoming drunk at least twice a month was most common in Wales (19%), Scotland (17%) and the North (17%) and least common in the East of England (9%). A total of 43% of respondents knew at least one or two people whom they felt drank to excess, while 12% had at least one family member whom they felt had an alcohol problem or dependency, and 4% stated that at least one family member had sustained liver injury due to alcohol. These findings were similar across socioeconomic strata and showed little geographical variation. Eighteen per cent of interviewees knew a family member or friend who had injured themselves while drunk, while 7% knew a family member or friend who had injured others. Twelve per cent knew a family member or friend who had been in trouble with the police through drinking and 21% knew someone who had driven an automobile while over the limit.
Frequency of alcohol consumption and prevalence of alcohol-related harms among survey population
Patterns of drinking and age
Young people (aged 18–24) drank less often than older people, but were more likely to drink heavily on those days when they did drink (figure 1). The survey identified a subset of people at all ages who drank very heavily (>40 units/week) and these heavy drinkers were significantly more likely to suffer alcohol-related harm than less heavy drinkers (figure 2). Young people mainly drank when out in pubs and clubs (39%), but strikingly, 30% of young people reported ‘pre-loading’—that is, drinking cheap supermarket alcohol at home at the start of the evening before going out. Compared with 18–24 year olds, respondents aged >54 years also drank more frequently at home (49% vs 12%, χ2=114.1, p<0.001), in association with a meal (45% vs 18%, χ2=61.7, p<0.001) and were less likely to drink in company (36% vs 60%, χ2=46.5, p<0.001). While the majority (73%) of these older drinkers drink within government daily recommended limits, 25% regularly drink to excess, with 8% drinking seven or more drinks on a typical drinking day. Despite this, most older drinkers denied becoming regularly drunk; with 81% stating that they never got drunk and only 2% reporting becoming drunk on two or more occasions a month.
Young people drink significantly less frequently than older people (A), but drink significantly more on each drinking day (panel B). Data are presented as mean ± SEM. **p<0.01; ***p<0.001 analysis of variance with Bonferroni correction.
The prevalence of alcohol-related self-harm is strongly associated with increasing average weekly alcohol consumption. Self-harm was defined as the sum of the following alcohol-related harms: caused injury to self; caused injury to others; trouble with police; emergency department attendance; unwanted pregnancy; relationship breakdown; domestic violence; alcohol dependency. Numbers above each column represent the weighted numbers of respondents at risk for each age group/pattern of alcohol consumption. ***p<0.001, χ2 test for trend.
Drink driving, personal dysfunctional behaviours and loss of productivity
Overall, 7% of respondents self-reported driving while they considered themselves to be over the legal alcohol limit. This was more common among older (aged >54) drinkers (9%) compared with 6% (χ2=2.4, p=0.12) of all younger (aged <54) drinkers. Drink-driving was also significantly more common in men than in women (11% vs 3%, χ2=54.9, p<0.001) and was more frequently reported by higher socioeconomic classes (ABC1) than respondents in classes C2DE (9% vs 6%, χ2=7.0, p=0.008).
Thirty six per cent of 18–24 year olds get drunk at least 2-4 times a month, with 27% having injured themselves while drunk and 4% having injured someone else while drunk. One per cent of all respondents reported having unintentionally caused a pregnancy or become pregnant while drunk, with identical reported rates across gender and social strata. Increasing average weekly alcohol consumption, age <55 years, male gender, never having been married and being in full-time employment were all independently associated with a history of alcohol-related self-harm (table 2).
Factors predictive of alcohol-related self-harm
Three per cent of those surveyed admitted to going to work feeling unwell as a result of alcohol at least twice a month and this was more common among young people (10%), than for all older drinkers (2%; χ2=53.4, p<0.001). Nine per cent of all interviewees and 10% of all current workers had taken time off owing to the effects of alcohol, yet only 1% of all workers had ever received a reprimand at work due to the after effects of alcohol and only 1% could recall receiving health advice at work about alcohol.
Gender effects
Men (88%) were significantly more likely to drink than women (82%, χ2=15.5, p<0.001), with 19% of men versus 11% of women (χ2=28.4, p<0.001) drinking ≥4 times/week. Multivariate logistic regression identified male gender as independently predictive of very heavy drinking (>40 units/week) (table 3). Men were more likely than women to exceed current recommended daily limits on a typical drinking day (50% vs 30%, χ2=92.3, p<0.001), with 11% of men drinking ≥10 drinks on the same day compared with 4% of women (χ2=34.8, p<0.001). Men were less likely than women to consume alcohol with food (27% vs 34%, χ2=12.8, p<0.001), but instead tended to drink mainly when out in pubs and clubs (30% vs 22%, χ2=18.6, p<0.001). Men (19%) were more likely than women (8%, χ2=59.0, p<0.001) to get drunk (ie, physically or mentally impaired) on at least 2-4 occasions a month and were more likely to have injured themselves or others while drunk (21% vs 13%, χ2=25.5, p<0.001). Men were also more likely to have taken time off work owing to alcohol consumption (12% vs 7%, χ2=16.2, p<0.001), to have driven over the legal alcohol limit (11% vs 3%, χ2=54.9, p<0.001) and to have been in trouble with the police (5% vs 1%, χ2=30.2, p<0.001) as a result of alcohol. Men were also more likely (5% vs 2%, χ2=13.9, p<0.001) to report dependency on, or addiction to, alcohol than women (table 4).

Employment and socioeconomic status
Respondents in regular employment (full-time or part-time) were more likely to drink ≥4 times/week compared with unemployed respondents (14% vs 3%, χ2=5.7, p=0.012). There were trends towards greater proportions of employed respondents drinking to excess on typical drinking days (45% vs 35%, χ2=2.2, p=0.14) and getting drunk at least twice a month (16% vs 9%, χ2=1.9, p=0.17). There were no significant differences in the proportions of employed and unemployed respondents who had injured themselves while drunk (17% vs 18%, respectively), been taken to an accident and emergency department owing to alcohol consumption (3% vs 3%), or driven while over the legal alcohol limit (8% vs 9%, respectively). Respondents in higher social classes ABC1 (‘middle class’) were significantly more likely to drink alcohol (88% vs 80%, χ2=15.5, p<0.001) than social classes C2DE (‘working class’) and were more likely to drink ≥4 times/week (18% vs 11%, χ2=21.2, p<0.001, (table 5). ABC1 classes drinkers were more likely to drink at home (40% vs 35%, χ2=5.8, p=0.018), to drink with a meal (34% vs 25%, χ2=20.9, p<0.001) and to drink mainly at the weekends (39% vs 32%, χ2=11.7, p=0.001) than C2DE drinkers. However, C2DE drinkers were slightly more likely to get drunk at least twice/month (16% vs 13%, χ2=4.0, p=0.045), with a tendency to drink above current recommended daily limits (42% vs 38%, χ2=3.8, p=0.06) and reported a greater influence of low-priced drinks (24% vs 18%, χ2=10.2, p=0.002), buy-one-get-one-free promotions (17% vs 13%, χ2=6.0, p=0.01) and cheap price promotions (25% vs 22%, χ2=2.4, p=0.13). Similar proportions of drinkers from both social classes reported self-injurious behaviour while drunk, but middle-class drinkers were more likely to have driven while above the legal alcohol limit (9% vs 6%, χ2=5.7, p=0.017), whereas working-class drinkers were more likely to have had trouble with the police as a result of drinking (4% vs 2%, χ2=6.0, p=0.014), or to have had a relationship breakdown as a result of alcohol (4% vs 2%, χ2=6.0, p=0.014).

Incentives and disincentives
Young people were heavily influenced by the effect of price, with 35% stating that drinks with the lowest price influenced them, compared with 21% of 25–34 year olds and just 13% of 35–44 year olds. This youngest age group was also most influenced by cheap price promotions (33%) compared with 22% of all older drinkers (χ2=14.9, p<0.001), or buy-one-get-one-free type promotions (28% vs 13%, χ2=35.3, p<0.001). Young people were more likely to choose high-strength alcohol or shots in order to rapidly become drunk (13%) compared with 4% of 25–34 year olds and <1% of older drinkers and tended to buy drinks thought less likely to cause a hangover (15% vs 11%, χ2=3.6, p=0.06).
Discussion
This large cross-sectional survey demonstrates the widespread use and abuse of alcohol throughout Great Britain. From a representative sample of 2221 individuals, this survey reveals that 15% of people drink four times a week or more, with 40% drinking over the recommended daily limits. The survey confirms the widespread nature of ‘binge’ drinking among young adults, with its attendant risks of personal injury and dysfunctional illegal or abusive behaviour. Chronic alcohol abuse is particularly prevalent; among older drinkers, of whom 25% regularly drink to excess, 8% drink seven or more drinks on a typical drinking day. The effects on young people are particularly alarming—36% of 18–24 year olds get drunk at least 2–4 times a month, 27% have injured themselves while drunk and 4% have injured someone else. Men appear to be at particularly high risk for heavy drinking independent of age, working status, or social class. The pervasive effects of this acute and chronic alcohol abuse in Great Britain are strikingly apparent from this survey: 18% of those interviewed knew a family member or friend who had injured themselves while drunk, 43% knew of at least one person who drinks to excess and 12% had at least one family member in this situation. Moreover, the harmful effects of excess alcohol are seen across all socioeconomic classes.
This independent survey provides additional information on alcohol use not available from the governmental GLS or other surveys of adults' drinking behaviour.6 In particular, this study is one of the few nationwide surveys to directly question interviewees about personal dysfunctional behaviour related to alcohol. The survey population was derived from an established YouGov representative panel of adults in Great Britain and therefore is likely to represent a true picture of overall drinking patterns. However, as with all cross-sectional surveys, this study represents only a snapshot of drinking patterns and we cannot directly infer causality or examine the longitudinal impact of the increased affordability of alcohol in Britain. Surveys of this type are dependent upon the accuracy of self-reported alcohol use, which may limit the accuracy of quantities consumed; however, previous data from the British Beer and Pub Association have suggested that drinkers tend to under-report consumption and therefore alcohol-related problems may be even more widespread than reported in this study.2
This study provides further evidence of the widespread use and abuse of alcohol throughout Great Britain. Overall, 57% of men and 47% of women reported drinking at least once a week, levels which are slightly lower than those reported by the 2009 GLS, which found that 68% of men and 54% of women had drunk alcohol in the preceding week.2 This may relate to the slightly different question used in the two surveys, or may reflect a recent downward trend in overall drinking rates. We found that 13% of 18–24 year olds and 11% of 25–54 year olds were drinking at levels associated with increased physical ill health (>20 and >40 units/week). This cohort of regular drinkers—the ‘liver deaths’ of the future—experienced more than three times as many acute harms even in the younger age groups. This is perhaps not surprising given that frequency of drinking occasions is perhaps the most important single question in the World Health Organisation risk assessment tool (AUDIT).7 This calls into question the government's controversial move from weekly to daily drinking guidelines.1 8 The switch from a weekly to a daily guideline proved to be a gift to the drinks industry and coincided with a sharp increase in rates of liver death.9
This study emphasises the impact and prevalence of alcohol-related antisocial behaviour, particularly among men and younger drinkers. Perhaps surprisingly, drinkers in full-time employment were also identified as at-risk for these antisocial behaviours. The results among 18–24 year olds, of whom 64% drank excessively on drinking days and 27% had injured themselves while drunk, are particularly striking. ‘Binge-drinking’, defined as feeling very drunk at least once a month, occurs most commonly in 18–24 year olds and is strongly associated with crime and antisocial behaviour, with a previous study reporting offending rates of 27% in young binge-drinkers compared with 13% of other young drinkers.10 Public health policies to target drinking in this age group are therefore urgently required. While ‘pre-loading’ at home was common among 18–24 year olds, this survey confirms previous research showing that young people purchase alcohol mainly in licensed premises11 and suggests that young people are particularly influenced by drinking venue and atmosphere. Additionally, young drinkers are swayed by price, with 33% being influenced to drink by cheap price promotions, 35% by the drink with the lowest price and 28% by buy-one-get-one-free offers. This survey therefore supports the conclusion that policies targeting cheap on-trade alcohol products and offers, such as a 10% increase in low-price on-trade alcohol, are likely to have the biggest influence in curbing excessive drinking among 18–24 year olds.11 The prevalence of drink-driving identified by this survey is also of considerable concern. A total of 7% of respondents self-reported driving while they considered themselves to be drunk and this rose to 9% of older drinkers and 9% of middle-class respondents, suggesting that drink-driving remains a significant problem in Great Britain. The implementation of random breath testing, which permits police to stop motorists who are not suspected of committing an offence, might have a sustained and significant impact upon this persistent problem.12
This survey also highlights the problem of excessive chronic drinking among older adults—over 20% of drinkers aged 55+ drink four or more times a week and it is likely that a substantial minority of these drinkers exceed governmental recommended limits. Interestingly, older drinkers also appear to be substantially influenced by price when buying alcohol, suggesting that pricing strategies such as raising the minimum price of a unit of alcohol to £0.50 could preferentially target this subgroup. Such minimum pricing strategies could reduce consumption by 6.9%, save 2930 lives a year and save £6.2 billion in health costs over 10 years.13
On 20 May 2010 the new coalition government published their strategy to tackle the harmful use of alcohol, which included banning the sale of alcohol for less than the combined tax and duty paid on it, along with a review of alcohol taxation and pricing to tackle binge-drinking ‘without unfairly penalising responsible drinkers, pubs and important local industries’. Although welcome, the impact of these policies alone upon the problem drinkers identified by this survey are likely to be limited,14 15 and there is an urgent requirement for a review of alcohol policy independent of the alcohol industry with the aim of introducing measures to target the youthful binge-drinking, drink-driving and chronic alcohol abuse among older people highlighted by this survey. Given that the affordability of alcohol in the UK increased by 65% between 1980 and 2006, interventions which target price are likely to have the greatest public health impact.
