Prevalence of self-reported alcohol consumption among pregnant women in Russia between 1994 and 2018.

Abstract

Although pregnant women in Russia are thought to have a high level of alcohol consumption, nationwide data have not been available. We compared changes in consumption among pregnant and nonpregnant women of childbearing age from 1994 to 2018 and examined predictors of consumption among the pregnant women. Data were obtained from the annual, nationally representative Russian Longitudinal Monitoring Survey (RLMS-HSE), comprising 1,943 pregnant and 80,237 nonpregnant women of childbearing age. Past 30-day alcohol prevalence and current pregnancy status were self-reported. Logistic regressions using generalized linear mixed models examined two dependent variables: (1) current drinkers (any alcohol in the past 30 days) versus nondrinkers and (2) current drinkers and occasional drinkers (ever drinkers at any level) versus nondrinkers. Analyses included a series of predictors and control variables. Between 1994 and 2018, a decrease in the 30-day prevalence of alcohol consumption was observed in both pregnant (from 25.6 (95% CI ± 3.3) to 9.4% (95% CI ± 2.2)) and nonpregnant (from 57.3 (95% CI ± 0.7) to 39.0% (95% CI ± 0.6)) women. Between 2006 and 2018, the percentage of pregnant abstainers increased from 46.8% (95% CI ± 4.2) to 54.6% (95% CI ± 3.6) while occasional drinking among pregnant women remained at 35% (95% CI ± 4.0). Time period, preventative check-ups, hospitalization, and frequent doctor's visits were significant predictors of the decrease in the 30-day prevalence of alcohol intake in pregnant women, but these did not predict the prevalence of occasional drinking. Despite significant reductions in consumption among pregnant women in Russia, a substantial proportion reported occasional drinking. Conflicting information on how low alcohol intake affects health risks limited efforts to promote abstinence. Occasional drinking reflects a self-control domain for women that, depending on perceptions of a healthy pregnancy, is framed by social institutions and the environment.
