In 2016, Kings College London attempted to conduct a study of alcohol consumption by Members of Parliament asking all 650 members to complete a short survey. Only 146 (22%) responded. (Median time taken by respondents was 4 minutes.) Older men were particular under-represented in the results.
Reseachers explained that:
Alcohol use among civil servants has been studied extensively in the Whitehall studies that explored social determinants of health, with clear findings of adverse effects on cardiovascular and cognitive function associated with drinking at levels above recommended guidelines. Although high workloads, job stress and using alcohol to unwind after work are known to be associated with risky drinking this has so far not been studied in UK parliamentarians.
We found a higher proportion of MPs with risky drinking compared with the English population and similar weighted proportions when compared with corporate managers, all managers and high-income groups.
The overall rate of risky drinking did not significantly differ from groups comparable in both socioeconomic and occupational status. However, the findings of higher weighted averages for drinking at least four times per week, drinking at least 10 units on a typical drinking day, drinking 6 units or more in a single drinking episode and feeling guilty about their drinking raises concerns both about overall weekly consumption and over possible binge drinking.
A weakness of the study was the low response rate felt to be due to:
a possible fear of being identified, of stigmatisation, and of the potential reputational damage associated with adverse media coverage may have influenced the response rate. We tried to reduce these biases by promoting the survey in parliament, by sending several reminders, and by stressing the brevity as well as the anonymity of the survey. In spite of this, the response rate was low. Generally, MPs are a difficult survey population to engage, which has also been confirmed in a 2008 internal UK parliament survey, where only 14.5% (94 MPs) responded.
