Alcohol consumption and binge drinking in Novosibirsk, Russia, 1985-95.

Aims: It has been suggested that the effects of alcohol, and binge drinking in particular, contributed to the dramatic fluctuations in Russian mortality rates: rapid decline in 1985-87, slow increase in 1988-91 and sharp increase in 1992-94. To date, there have been no data available to substantiate this claim. We examine for the first time the trends in alcohol intake and binge drinking in a Russian urban population.
Methods: Independent random samples of men and women aged 25-64 in two districts of Novosibirsk city (Western Siberia) have been examined in 1985/86 (1535 men and 1296 women), 1988/89 (1700 men, no women), and 1994/95 (1539 men and 1511 women). Response rates ranged from 71% to 73%. The subjects reported frequency of drinking alcohol, average amount of alcohol consumed at a typical occasion, and their alcohol intake in the week preceding the interview. Two cut-off points to define binge drinking were adopted: > or = 80 g and > or = 120 g at a single occasion.
Results: The proportion of men who drank at least once a week increased from 27% in 1985/86 to 38% in 1994/95; corresponding figures among women were 0.6% and 6.5%, respectively. The mean consumption of pure alcohol at a single occasion in men was 90 g in 1985/86, 119 g in 1988/89 and 112 g in 1994/95; in women, it was 33 g in 1985/86 and 32 g in 1994/95. Between the first and the last survey, the mean weekly intake of pure alcohol increased from 120 g to 184 g in men and from 31 g to 41 g in women. Prevalence rates of binge drinking (> or = 80 g at least once a month) in the three surveys were 36%, 52% and 51%, respectively, in men, and 0.4% in the first and 5% in the last survey among women.
Conclusion: Alcohol consumption and prevalence of binge drinking were high in men and low in women. The frequency of binge drinking among men increased between 1985/86 and 1988/89 and remained stable between 1988/89 and 1994/95. This is not consistent with trends in mortality. Shorter-term fluctuations between surveys, however, cannot be excluded.
