Treated and treatment-naive alcoholics come from different populations.

In most research on alcoholism, convenience samples of individuals who have been in some type of treatment are used. Berkson's fallacy results when the associations found in studies of select samples are incorrectly presumed to apply to all alcoholics (i.e., including untreated alcoholics in the general population). In the current study, we examined whether treated and untreated alcoholics have similar early alcohol use histories by comparing abstinent alcoholics (treated and sober at least 6 months) with treatment-naive alcoholics (active drinkers). We studied 14 pairs of women and 25 pairs of men matched on the age at which they first met criteria for heavy alcohol use (women, 80 drinks per month; men, 100 drinks per month). The timeline follow-back interview method was used to gather retrospective alcohol use information. Alcohol dose and duration of use were subsequently computed for two intervals: (1) time between the person's first drink and date at which the person met criteria for heavy drinking and (2) period between when criteria for heavy drinking were met and current age of the treatment-naive person from each pair. During the period before the matching "heavy drinking" criteria were met, alcohol dose did not differ between groups. In the period after criteria for heavy alcohol use were met, in comparison with treatment-naive alcoholics, the treated alcoholics had higher average and peak alcohol doses. We rejected the hypothesis that the treatment-naive alcoholics and the treated alcoholics have similar alcohol use trajectories over time, with the treatment-naive sample simply being observed earlier in its alcohol use histories. Instead, we concluded that the two groups come from different populations with regard to alcohol use. In fact, the treated alcoholics had alcohol doses more than 50% higher than those of treatment-naive alcoholics in the years just after they began drinking heavily. This finding supports the suggestion that results from studies of alcoholics in treatment or after treatment (i.e., most studies of alcoholics) cannot be generalized to untreated individuals (who make up the majority of alcoholics).

Sex differences in spatial visualization and episodic memory as a function of alcohol consumption

AIMS: Sex differences in visuospatial ability as well as episodic memory have been reliably demonstrated, irrespective of alcoholism. Studies in alcoholics have consistently documented cognitive deficits in visuospatial ability, problem solving and memory function. This cross-sectional, population-based study examined if sex differences in cognitive performance could be impacted by alcohol consumption. METHODS: Drinking data were collected from 2224 randomly sampled adults, aged between 35 and 85 years, who participated in the Betula study on memory, health and aging. Participants were classified into non-, light, moderate and heavy drinking subgroups based on sex-adjusted normative values. Cognitive tasks demonstrating clear sex differences, such as episodic memory tasks (favouring women) and spatial visualization tasks (favouring men), were conducted and performance was assessed by sex and the drinking group. RESULTS: After controlling for age and education, overall analyses found expected sex differences in episodic memory and spatial visualization that were apparent across the entire population. When these sex differences were examined by drinking group, visuospatial performance favouring men disappeared for the moderate to heavy drinking groups, but higher performance by women on episodic memory tasks was consistent across all levels of alcohol consumption. Traditional biomarkers of increased alcohol consumption (GGT and MCV) correlated with the reported drinks/day. CONCLUSIONS: These results lend support to the theory that moderate alcohol intake may be beneficial to cognitive function in women, but not necessarily in men.     

Alcohol Use and Sexual Risks for HIV/AIDS in Sub-Saharan Africa: Systematic Review of Empirical Findings

Alcohol consumption is associated with risks for sexually transmitted infections (STI), including HIV/AIDS. In this paper, we systematically review the literature on alcohol use and sexual risk behavior in southern Africa, the region of the world with the greatest HIV/AIDS burden. Studies show a consistent association between alcohol use and sexual risks for HIV infection. Among people who drink, greater quantities of alcohol consumption predict greater sexual risks than does frequency of drinking. In addition, there are clear gender differences in alcohol use and sexual risks; men are more likely to drink and engage in higher risk behavior whereas women's risks are often associated with their male sex partners' drinking. Factors that are most closely related to alcohol and sexual risks include drinking venues and alcohol serving establishments, sexual coercion, and poverty. Research conducted in southern Africa therefore confirms an association between alcohol use and sexual risks for HIV. Sexual risk reduction interventions are needed for men and women who drink and interventions should be targeted to alcohol serving establishments.     

Alcohol consumption, drinking pattern and blood pressure: analysis of data from the Italian National Research Council Study

The present analyses addressed the relationship between alcohol consumption, drinking patterns and hypertension in 6699 Italian men and women participating in a national project on arteriosclerosis risk factors. The results of the analyses are consistent with an association between heavy alcohol consumption and systolic blood pressure in both males and females. Higher diastolic blood pressure was associated with heavy alcohol consumption in men but not in women. Drinkers of wine both with and without meals have a higher prevalence of hypertension than abstainers in both sexes. We conclude that heavy alcohol consumption is associated with higher blood pressure values, and that the pattern of drinking could be an important determinant in the association between alcohol and hypertension.     

Alcohol use in pregnancy, craniofacial features, and fetal growth.

STUDY OBJECTIVE--The aim was to study the relationship between the level of alcohol consumption in pregnancy and craniofacial characteristics of the neonate. DESIGN--This was a prospective survey of a sample of pregnant women, stratified on prepregnancy level of alcohol consumption. SETTING--The study was carried out at the public antenatal clinic of Roubaix maternity hospital. PARTICIPANTS--During an eight month period, 684 women (89% of those eligible) were interviewed in a standardised way at their first antenatal clinic visit. Of these, all who were suspected of being alcoholic or heavy drinkers (at least 21 drinks per week) were selected for follow up, as was a subsample of light (0-6 drinks per week) and moderate (7-20 drinks per week) drinkers. Of 347 women selected in this way, 202 had their infants assessed by a standardised morphological examination. MEASUREMENTS AND AND MAIN RESULTS--Suggestive craniofacial characteristics of the infants, present either in isolation or in association with growth retardation ("fetal alcohol effects"), were compared in relation to maternal alcohol consumption (alcoholic 12%; heavy drinking 24%; moderate drinking 28%; light drinking 36%). No differences were found between light and moderate drinkers. Infants born to alcoholics had a greater number of craniofacial characteristics and the proportion with features compatible with fetal alcohol effects was higher. There was a similar trend for infants of heavy drinkers. Infants of heavy drinkers who had decreased their alcohol consumption during pregnancy had fewer craniofacial features. Infants of heavy smokers were also found to have increased numbers of craniofacial characteristics. CONCLUSIONS--Craniofacial morphology could be a sensitive indicator of alcohol exposure in utero. Altered morphology is usually considered specific for alcohol exposure, but the relation observed with smoking needs further exploration.     

Pregnancy, Alcohol Intake, and Intimate Partner Violence among Men and Women Attending Drinking Establishments in a Cape Town, South Africa Township

The highest rates of fetal alcohol syndrome worldwide can be found in South Africa. Particularly in impoverished townships in the Western Cape, pregnant women live in environments where alcohol intake during pregnancy has become normalized and interpersonal violence (IPV) is reported at high rates. For the current study we sought to examine how pregnancy, for both men and women, is related to alcohol use behaviors and IPV. We surveyed 2,120 men and women attending drinking establishments in a township located in the Western Cape of South Africa. Among women 13.3% reported being pregnant, and among men 12.0% reported their partner pregnant. For pregnant women, 61% reported attending the bar that evening to drink alcohol and 26% reported both alcohol use and currently experiencing IPV. Daily or almost daily binge drinking was reported twice as often among pregnant women than non-pregnant women (8.4% vs. 4.2%). Men with pregnant partners reported the highest rates of hitting sex partners, forcing a partner to have sex, and being forced to have sex. High rates of alcohol frequency, consumption, binge drinking, consumption and binge drinking were reported across the entire sample. In general, experiencing and perpetrating IPV were associated with alcohol use among all participants except for men with pregnant partners. Alcohol use among pregnant women attending shebeens is alarmingly high. Moreover, alcohol use appears to be an important factor in understanding the relationship between IPV and pregnancy. Intensive, targeted, and effective interventions for both men and women are urgently needed to address high rates of drinking alcohol among pregnant women who attend drinking establishments.     

Starving for a drink: Sexual objectification is associated with food-restricted alcohol consumption among college women,but not among men

ABSTRACT

Interpersonal sexual objectification, or being treated as an object by others, is linked to poorer body image and, in turn, engagement in weight management behaviors that promote conformity to unrealistic appearance standards while simultaneously undermining health. Although these associations emerge consistently among women, the evidence has been less clear among men. The present study introduced a novel weight control behavior, food-restricted alcohol consumption (i.e., limiting food intake prior to alcohol consumption), and examined whether sexual objectification was associated with this phenomenon and whether this association differed among women and men. During the fall of 2012 and the spring of 2013, 410 undergraduates reported how often they felt objectified by others and restricted what they ate before drinking alcohol in the past month. Controlling for past drinking, sexual objectification was significantly and positively associated with food-restricted alcohol consumption for women; however, sexual objectification was unrelated to food-restricted alcohol consumption for men. The results suggest that sexual objectification might operate differently across the sexes and particularly be related to this specific health-risk behavior among women.     

Carbohydrate-deficient transferrin as compared to other markers of alcoholism: a systematic review.

This is a systematic review of the studies in which carbohydrate-deficient transferrin (CDT) has been compared to other laboratory markers in different experimental conditions, clinical settings, and populations. Only the studies (n = 54) in which CDT was compared either to the conventional or new biological markers of alcoholism, heavy drinking, or alcohol use were selected for further evaluation. Two prospective studies indicate that in men CDT is slightly more sensitive than gamma-GT in reflecting changes in these markers caused by drinking of a moderate and fixed amount of alcohol during three to four weeks. In one prospective study, in which the drinking history of male heavy drinking volunteers was as close the golden standard as possible; that is, obtained by a prospective anonymous drinking diary, CDT was slightly but not significantly better marker than conventional laboratory markers (ASAT, ALAT, gamma-GT and beta-Hex) in the identification of men drinking more than 400 g of alcohol daily. Similar prospective studies concerning women have not been done. Six prospective treatment outcome studies indicate that CDT may be a significantly more sensitive marker than gamma-glutamyltransferase (gamma-GT) in the detection of relapses in male alcoholics. However, these two tests can also be considered to be complementary markers. Furthermore, in the detection of relapses the baseline values of CDT and gamma-GT should be measured and compared on individual basis to the pretreatment values. Comparable data are not available from female alcoholics. In selective materials comprising male alcoholics and heavy drinkers, CDT was found to be a slightly more sensitive marker than gamma-GT in seven retrospective studies. In five studies, gamma-GT was slightly better. However, the differences between CDT and gamma-GT in general were not statistically significant. In three studies, the combined use of CDT and gamma-GT improved the sensitivity but with the expense of specificity. Only four studies included women and in three of these the sensitivity of gamma-GT was better than that of CDT, whereas in one study CDT was better than gamma-GT in the detection of female heavy drinkers. Seven studies performed in primary health care settings and among young populations demonstrate that the performance of CDT in the identification of heavy and problem drinkers in this type of populations is very low, although comparable to the poor performance of the conventional laboratory markers, too. According to seven studies, the sensitivity of gamma-GT is slightly better than that of CDT in the identification of excessive alcohol consumption among hospitalized male and female patients. However, in this type of hospital setting, the specificity of CDT is markedly higher than that of gamma-GT. There is some evidence indicating that the performance of the tests can be improved with the combined use of both tests. Eight studies indicate that both in men and women CDT is a better marker than gamma-GT in the identification of alcohol abuse among patients with alcoholic and nonalcoholic liver diseases. This is mostly due to the higher specificity of CDT as compared to that of gamma-GT.     

Gender differences in the relationship between alcohol consumption and drink problems are largely accounted for by body water

It is widely reported that women drink less and have a lower prevalence of drink problems than men, but the gender differences in the relationship between level of drinking and drink problems have rarely been investigated quantitatively. This paper reports results from the Medical Research Council National Survey of Health and Development (the 1946 British Cohort) when the subjects were 43 years old. Using 7-day recall for alcohol consumption and CAGE scores of 2, 3 or 4 for drink problems, it was found that the prevalence of drink problems increased with level of alcohol consumption. Women were more likely than men to report drink problems at the same level of alcohol consumption. However, this gender difference was largely accounted for by individual differences in weight of body water. Beer accounted for the excess of men's drinking over women's and the proportion of alcohol consumed as beer was inversely related to drink problems. Eighty per cent of women and 52% of men who had drink problems in the past year reported drinking less than an average of 3 U (women) or 4 U (men) a day in the past week. As drinking levels in women begin to approach those in men, rates of drink problems in women are likely to overtake those in men because of women's greater physiological sensitivity to the effects of alcohol.     

Poor health is associated with episodic heavy alcohol use: evidence from a National Survey

OBJECTIVES: The objective of this study was to examine the relationship between self-rated health and episodic heavy drinking in a representative sample of American adults. We also sought to determine ethnic and gender differences in the association between self-rated health and episodic heavy drinking. METHODS: Data (n=4649) from the Third US National Health and Nutrition Examination Survey were utilized for this investigation. Episodic heavy drinking was defined as the consumption of five or more and four or more alcoholic beverages on one occasion for men and women, respectively. Poor health was defined as answering fair or poor to the question: "Would you say your health in general is excellent, very good, good, fair or poor?" Odds ratio from the logistic linear regression analysis was used to estimate the risk for poor health that was associated with episodic heavy drinking. Statistical adjustments were made for age, hypertension, diabetes, current smoking, body mass index and race/ethnicity. RESULTS: Overall, episodic heavy drinking was associated with increased odds of poor self-rated health in men and women. In men, episodic heavy drinking was independently associated with 1.28 (95% CI: 1.07-1.82) increased odds of poor health. The corresponding value in women was 1.86 (95% CI: 1.05-2.28). In men, being Black was associated with approximately two-fold (OR=1.96; 95% CI: 1.33, 2.89), and being Hispanic was associated with approximately four-fold (OR=3.59; 95% CI: 2.50, 5.14) increased odds of poor self-rated health relative to being White. The corresponding odds ratios in women were 2.97 (95% CI: 1.90, 4.64) and 5.18 (95% CI: 3.23, 8.30). Associations were greater among blacks (adjusted OR=2.41; 95% CI: 1.81-3.22) and Hispanics (adjusted OR=4.15; 95% CI: 3.12-5.52) than among whites. CONCLUSIONS: Poor health is associated with episodic heavy alcohol consumption. Public health strategies to curb alcohol abuse may improve self-reported health status in these at-risk populations.     

Concordant alcohol and marihuana use in women

Alcohol and marihuana use are common among both sexes, but systematic data on drug use patterns by women previously have been unavailable. This report describes the first prospective study of alcohol and marihuana consumption patterns in women, and examines factors that promote or maintain concurrent use. Thirty healthy adult women (mean age = 26.4 years) completed daily questionnaires for 3 consecutive menstrual cycles. Subjects recorded quantities and times of alcohol and marihuana consumption, episodes of sexual activity, and occurrence of unusual life events. Temporal variables significantly affected both alcohol and marihuana consumption. Marihuana use occurred earlier in the day than alcohol use. Significantly greater marihuana consumption and more concordant alcohol and marihuana use occurred on weekends. Older subjects (26 to 30) exhibited more concordant alcohol and marihuana use than younger subjects (21 to 25). Significant differences in alcohol use also distinguished heavy from light marihuana smokers. Neither sexual activity nor unusual events were associated with concordant alcohol and marihuana consumption in all subjects.     

Self-reported childhood sexual and physical abuse and adult HIV-risk behaviors and heavy drinking

CONTEXT: Although studies of clinical samples have identified links between childhood abuse, especially sexual abuse, and adult health-risk behaviors, the generalizability of these findings to the population and the relative importance of different types of abuse in men and women are not known. OBJECTIVE: To estimate the risk of self-reported adult HIV-risk behaviors and heavy drinking that is associated with self-reported childhood histories of physical and/or sexual abuse for men and women in a general-population sample, after controlling for age and education. A second objective is to determine whether, among women, early and chronic sexual abuse is associated with heightened risk compared to later or less extensive abuse. DESIGN: A population-based telephone survey, the 1997 Washington State Behavioral Risk Factor Surveillance System (BRFSS), asked a representative sample of adults whether they had ever been physically or sexually abused in childhood, and if so, the age at first occurrence and number of occurrences. The survey also asked about levels of alcohol use and, for those under 50 years, about HIV-risk behaviors. PARTICIPANTS: Three thousand four hundred seventy-three English-speaking non-institutionalized civilian adults in Washington State. MAIN OUTCOME MEASURES: Self-reported HIV-risk behaviors in the past year and heavy drinking in the past month. RESULTS: We identified associations between reported abuse history and each health-risk behavior that we examined. For women, early and chronic sexual abuse (occurring without nonsexual physical abuse) was associated with more than a 7-fold increase in HIV-risk behaviors (odds ratio [OR], 7.4; 95% confidence intervals [CI] 2.4 to 23.5); and any sexual abuse, combined with physical abuse, was associated with a 5-fold increase in these risk behaviors (OR, 5.0; 95% CI, 2.2 to 11.5). For women, only combined sexual and physical abuse was associated with heavy drinking (OR, 6.2; 95% CI, 2.2 to 16.9). Physical abuse alone was not associated with either health-risk behavior for women. For men, any sexual abuse was associated with an 8-fold increase in HIV-risk behaviors (OR, 7.9; 95% CI, 1.8 to 35.1). Physical abuse alone was associated with a 3-fold increase in risk of HIV-risk behaviors (OR, 3.2; 95% CI, 1.3 to 7.9) and a similar increase in risk of heavy drinking (OR, 3.2; 95% CI, 1.8 to 5.5). Although only 29% of the women and 19% of the men who were asked about HIV-risk behaviors reported any history of childhood abuse, these accounted for 51% and 50% of those reporting HIV-risk behaviors, respectively. For heavy drinking the corresponding figures were 25% of the women and 23% of the men reporting any abuse, who accounted for 45% and 33% of those reporting heavy drinking, respectively. CONCLUSIONS: Efforts to prevent or remediate adult health-risk behaviors should consider the possibility of a history of childhood abuse, as one third to one half of those reporting HIV-risk behaviors or heavy drinking in a general-population survey also reported childhood abuse.     

Drinking pattern and alcohol-related medical disorders.

Although heavy alcohol intake is known to be one of the most common causative factors of liver disease, pancreatitis, upper gastrointestinal and neurological disorders, the influence of the drinking pattern is largely unknown. The study investigated the relationship of alcohol-related medical disorders in alcoholics and their drinking pattern. Two hundred and forty-one chronic alcoholics were referred consecutively for detoxification and their drinking pattern was sufficient for them to be included in this study. History of alcohol abuse as well as drinking behaviour in the last 6 months were assessed by a semi-structured interview. Findings included intensive clinical examination with abdominal ultrasound in most subjects. Heavy drinking with frequent inebriation was most often found in our sample (44.4%), whereas continuous heavy alcohol consumption without intoxication (33.6%), and an episodic drinking style (22.0%) were less frequent. The heavy drinkers suffered more often from pancreatitis, oesophageal varices, polyneuropathy or erectile dysfunction than episodic drinkers. They also showed more upper gastrointestinal disorders, although the estimated life-time alcohol intake was comparable to continuous drinkers. No difference relating to withdrawal delirium or seizures could be found between the groups of alcoholics. Frequent heavy drinkers showed a trend to more alcohol-related medical disorders than alcoholics with a different drinking pattern, although they were younger and their estimated life-time alcohol intake was comparable to that of continuous drinkers. Thus, the drinking pattern, particularly frequent inebriation, has an influence on the occurrence of alcohol-related disorders.     

Alcohol, sex and AIDS

The association between alcohol consumption and AIDS risks is examined. It is concluded that chronic heavy drinking or alcohol consumption levels consistent with alcohol dependence or alcohol-related liver disease does damage the immune system. In addition alcohol consumption influences sexual behaviour for a variety of psychological, social and physical reasons. Attention is focused on the disinhibiting effects of alcohol and the popular belief that drinking may be used to facilitate or excuse otherwise unacceptable behaviour. Several studies indicate that alcohol consumption is associated with 'high risk' sexual behaviour. Accordingly drinking appears to be a risk factor for potential exposure to HIV infection and for relapse into 'high risk' sexual activities. Evidence does not support the conclusion that alcohol is a cofactor in the course of AIDS-related illnesses.     

Women''s drinking and drinking problems: patterns from a 1981 national survey

A 1981 national survey of women's drinking interviewed 917 women in the general population, stratified on the basis of screening interviews to include 500 moderate-to-heavy drinkers. The survey found no evidence of any major recent increase in women's drinking, and no evidence of unusually heavy drinking among working wives. Adverse drinking consequences and episodes of extreme drinking were most common among women aged 21-34; women who were unmarried, divorced or separated, or cohabiting; and women with frequent drinkers as spouses or companions. Alcohol-related behavior problems and symptoms of alcohol dependence were closely related to levels of alcohol consumption. Among women averaging one ounce or more of ethanol per day, 45 per cent had driven while intoxicated in the past year, and 36 per cent reported memory lapses while drinking. Women at this consumption level were also more likely to report experiences with depression (61 per cent). Women with extremely high consumption levels were more likely to have histories of obstetrical and gynecological problems. Some women with alcohol-related problems reported periods of temporary abstention, a pattern not studied heretofore.     

Contribution of drinking patterns to differences in rates of alcohol related problems between three urban populations

OBJECTIVES: To examine, on empirical data, whether drinking patterns, in addition to overall alcohol consumption, contribute to differences in rates of alcohol related problems between populations. DESIGN: Cross sectional survey. SETTINGS: One Russian, one Polish, and one Czech city. PARTICIPANTS: 1118 men and 1125 women randomly selected from population registers. MAIN OUTCOME MEASURES: Problem drinking; negative social consequences of drinking; alcohol consumption and drinking pattern. RESULTS: Rates of problem drinking and of negative consequences of drinking were much higher in Russian men (35% and 18%, respectively) than in Czechs (19% and 10%) or Poles (14% and 8%). This contrasts with substantially lower mean annual intake of alcohol reported by Russian men (4.6 litres) than by Czech men (8.5 litres), and with low mean drinking frequency in Russia (67 drinking sessions per year, compared with 179 sessions among Czech men). However, Russians consumed the highest dose of alcohol per drinking session (means 71 g in Russians, 46 g in Czechs, and 45 g in Poles), and had the highest prevalence of binge drinking. In women, the levels of alcohol related problems and of drinking were low in all countries. In ecological and individual level analyses, indicators of binge drinking explained a substantial part of differences in rates of problem drinking and negative consequences of drinking between the three countries. CONCLUSIONS: These empirical data confirm high levels of alcohol related problems in Russia despite low volume of drinking. The binge drinking pattern partly explains this paradoxical finding. Overall alcohol consumption does not suffice as an estimate of alcohol related problems at the population level.     

Black-white differences in alcohol use by women: Baltimore survey findings

Although black women suffer disproportionately from alcohol-related illnesses and causes of death, little is known about the extent to which poorer outcomes are a function of differences in drinking, the use of health services, or some combination of these factors. This study, using interview data obtained in the Baltimore Epidemiologic Catchment Area household survey, compares racial differences in alcohol use and abuse among a sample of 2,100 women. After controlling for differences in sociodemographic characteristics, black women were found to be at no greater risk than whites for heavy drinking or for suffering from alcohol abuse or dependence. Racial differences, however, were observed in heavy drinking by years of education. A similar percentage of black women and white women who had not completed high school were heavy drinkers, but black women with 12 or more years of education were less likely to be heavy drinkers than whites with comparable education. These findings raise questions about the extent to which differences in drinking contribute to the poorer alcohol-related health outcomes of black women in Baltimore. Additionally, the finding that education was inversely related to heavy drinking among black women may be helpful in shaping early alcohol abuse intervention and treatment services that target black women.     

Exploring the Relationships Among Food Insecurity,Alcohol Use,and Sexual Risk Taking Among Men and Women Living in South African Townships

South African townships have among the highest rates of HIV infection in the world. Considerable research on understanding the high rates of HIV transmission in this country has identified alcohol use as a critical factor in driving the HIV epidemic. Although the relationship between alcohol use and sexual risk-taking is well documented, less is known about how other factors, such as food insecurity, might be important in understanding alcohol’s role in sexual risk-taking. Furthermore, prior research has highlighted how patterns of alcohol use and sexual risk-taking tend to vary by gender. We examined how food insecurity is related to both alcohol use and sexual risk-taking. We administered anonymous community surveys to men (n = 1,137) and women (n = 458) residing within four contiguous Black African townships outside of Cape Town, South Africa. In multivariate linear regression, we found that food insecurity was related to having higher numbers of male sex partners and condom-protected sex acts among women only. These relationships, however, were fully mediated by women’s alcohol use. Among men, we found that food insecurity was negatively related to unprotected sex; that is, men with greater food security reported more unprotected sex acts. Unlike the results found among women, this relationship was not mediated by alcohol use. Food insecurity appears to be an important factor in understanding patterns of sexual risk-taking in regards to gender and alcohol use, and may serve as an important point of intervention for reducing HIV transmission rates.
