ABSTRACT Women appear to become more impaired than men after drinking equivalent amounts of alcohol, achieving higher blood alcohol concentrations even when doses are adjusted for body weight. This finding may be attributable in part to gender differences in total body water content. Men and women appear to eliminate approximately the same total amount of alcohol per unit body weight per hour. However, women seem to eliminate significantly more alcohol per unit of lean body mass per hour than men. Some studies report that women are more susceptible than men to alcohol-related impairment of cognitive performance, especially in tasks involving delayed memory or divided attention functions. Psychomotor performance impairment, however, does not appear to be affected by gender. This article provides an overview of alcohol metabolism (pharmacokinetics) and reviews recent studies on gender differences in alcohol absorption, distribution, elimination, and impairment. Speculation that gender differences in alcohol pharmacokinetics or alcohol-induced performance impairment may be caused by the menstrual cycle and variations in female sex hormones are discussed. It is concluded that the menstrual cycle is unlikely to influence alcohol pharmacokinetics.

    ABSTRACT: Abstract Aim: The aim of this paper is to provide a critical review of the most recent literature from 2005 onwards, on the effect of alcohol intake during lactation on the hormonal control of lactogenesis; breastmilk alcohol concentration; the breastfeeding infant, and on the breastfeeding outcomes of the mother and infant dyad. An update on public policy guiding alcohol consumption during lactation nationally and internationally is explored. Methods: The databases PubMed, CINAHL, Proquest Health and Medical Complete, ScienceDirect, Medline and ISI Web of Knowledge were searched from 2005 onwards. Results: Alcohol inhibits the role of oxytocin in breastfeeding women, resulting in an increased time to milk ejection and a decrease in total breastmilk yield. Breastfeeding women are less likely to consume alcohol at high-risk levels, and drinking at these levels is associated with the early cessation of breastfeeding. A higher level of education and a higher income level are the characteristics of the maternal drinker during lactation. Conclusion: Available public health policy in Australia provides direction for breastfeeding mothers who choose to drink alcohol during this important stage of infant development.

    ABSTRACT: Underage drinking and alcohol abuse by college students are of major concern both for the individuals and for all those in the campus community. This paper reviews the extent of the problem currently and in an historical perspective. It also reviews research concerning the immediate and long-term health and social outcomes of binge drinking, along with the “second hand” effects for those around the drinkers. Profiles of those individuals and groups most at risk for problem drinking are suggested. It also provides examples of efforts to prevent or reduce collegiate drinking, including campus-community coalitions, environmental management and social marketing campaigns. Additional resources and further suggestions for a comprehensive prevention effort are included.

    ABSTRACT: In the present work we studied the effects of four alcoholic beverages on blood alcohol levels, plasma insulin concentrations and plasma glucose concentrations in men and women. The volunteers were healthy non-smokers and they were divided according to sex into two groups of ten individuals. The alcoholic beverages used in the study were beer, red wine, whisky and “cachaça”. In men, ingestion of the distilled drinks promoted a spike in blood alcohol levels more quickly than ingestion of the fermented drinks. In women, beer promoted the lowest blood alcohol levels over the 6 h of the experiment. Whisky promoted highest blood alcohol levels in both sexes. The ingestion of wine promoted a significant difference in relation to the blood alcohol concentration (BAC) as a function of gender. The ingestion of cachaça by women produced BAC levels significantly smaller than those obtained for wine.
