To the Editor: In their article on risk-taking behaviour among young Australian women, Carr-Gregg and colleagues make a number of statements about alcohol consumption among young women.1 Unfortunately, these statements are not supported by the facts.

The authors assert, citing a national study of 14 762 women aged 18–23 years,2 that “seventy percent of young women engage in ‘binge drinking’ (5 or more drinks on one occasion) at some time, with 19% doing so on a weekly basis”. The level and frequency of alcohol consumption that constitutes “binge drinking” is a matter of conjecture. The National Health and Medical Research Council (NHMRC), in guidelines released in 2001,3 state that “binge drinking” is “not a preferred term due to its lack of consistent and specific meaning”.

The NHMRC guidelines on short term risk specify 5–6 alcoholic drinks for a female on any one day as being “risky” for health, and 7 drinks or more being “high risk”. For long term risk, 3–4 drinks on an average day, or 15–28 drinks a week, is considered “risky”, with any more constituting “high risk”.

Applying these guidelines to the Women’s Health Australia dataset shows that 5.1% of young women engage in drinking that is “risky” or “high risk” in the long term. Of the remaining 94.9%, 14.4% drink 5 or more drinks weekly or more, and 51.9% drink five or more drinks monthly or less. This is a more revealing (and accurate) picture than the blanket statement that “70% of young women are ‘binge drinkers’ ”.

Carr-Gregg and colleagues also claim that “22% of females aged 14–19 years drink between 9 and 30 alcoholic drinks a day”. The source for this statement is a survey conducted for the Salvation Army.4 The survey has several limitations, not least the small sample size. The survey sampled 614 respondents, of whom 70 were aged 14–19 years. The assertion that 22% of females in this age category were “binge drinkers” is based on just seven respondents. This number is well below what is required for any reliable statistical estimation.

Encouraging responsible drinking among younger people is a major goal of health professionals and the alcohol industry. A constructive policy debate on this issue requires sound, objective evidence about alcohol consumption among younger people. The article by Carr-Gregg et al does not represent progress towards providing that evidence.
