One in five older people who drink alcohol are consuming it at unsafe levels - over 21 units of alcohol for men and 14 units for women each week - according to a study by King's College London. The research in inner-city London, published in BMJ Open, found these unsafe older drinkers are more likely to be of higher socioeconomic status.

The researchers used anonymised electronic GP health records for 27,991 people aged 65 and over in the Borough of Lambeth in London. From these records, they identified 9,248 older people who had reported consuming alcohol and of these 1,980 people drank at unsafe levels.

They found unsafe drinkers were more likely to be male, younger and have higher socioeconomic status. Men were more likely to be unsafe drinkers than women - 46% of people in the study were male, but they were 60% of the drinkers and 65% of the unsafe drinkers.

Dr Tony Rao, lead author from the Institute of Psychiatry, Psychology & Neuroscience at King's College London said: 'As the Baby Boomer generation become seniors, they represent an ever increasing population of older people drinking at levels that pose a risk to their health. This study shows the need for greater awareness of the potential for alcohol related harm in older people, particularly those of higher socio-economic status, who may suffer the consequences of ill health from alcohol at an earlier age than those in previous generations.'

The median alcohol consumption was 6 units per week for all over-65s who reported drinking. However, the top 5% of alcohol drinkers reported consuming more than 49 units per week for men and more than 23 units per week for women.

Dr Mark Ashworth, study author from the Division of Health and Social Care Research at King's College London said: 'This research highlights that as GPs we need be more aware of the risk of older people, especially men, drinking excessively. Reducing alcohol misuse is important to prevent premature death and serious negative health effects, such as alcoholic liver disease, which are big burden on our health system. Alcohol excess carries additional risks in the older population such as falls and confusion.'

Alcohol drinkers were also more likely to be ethnically White or Irish, while people from Caribbean, African or Asian ethnicities were less likely to drink. People of White ethnicity were 59% of the study population, but were 68% of those who reported drinking alcohol and 80% of the unsafe drinkers. People of Irish ethnicity were 5% of the study population, but were 6% of the alcohol drinkers and 8% of the unsafe drinkers.

Dr Ashworth added: 'Based on our findings, the elderly who were most at risk were those from the white British population rather than from an ethnic minority, and those who were wealthier and better educated rather than those from a more deprived background.'

The authors caution that results from inner-city London may not apply to other areas of the UK with different demographics. They also note that while the study contains an almost complete sample of older people in the area, people may have under-reported their alcohol consumption to their GP.
