Dying to be equal: women, alcohol, and cardiovascular disease

Substance use in women: Current status and future directions

Alcohol and substance use, until recently, were believed to be a predominantly male phenomenon. Only in the last few decades, attention has shifted to female drug use and its repercussions in women. As the numbers of female drug users continue to rise, studies attempt to understand gender-specific etiological factors, phenomenology, course and outcome, and issues related to treatment with the aim to develop more effective treatment programs. Research has primarily focused on alcohol and tobacco in women, and most of the literature is from the Western countries with data from developing countries like India being sparse. This review highlights the issues pertinent to alcohol and substance use in women with a special focus to the situation in India.

Barriers and facilitators for alcohol treatment for women: are there more or less for rural women?

Among women at-risk for problems drinking, treatment seeking can be hindered by a complex array of issues such as a lack of transportation, social stigma, denial, fear of losing children, and reluctance of primary care physicians to refer women. This study describes the barriers/facilitators and need for treatment among a community sample of rural and urban women at-risk drinkers. Data for this study were assembled from the baseline sample of individuals who participated in a large probability sample of rural and urban at-risk drinkers (N = 733) from six Southern states: Alabama, Arkansas, Georgia, Louisiana, Mississippi, and Tennessee. Men and women differed on perceived barriers/facilitators and need for alcohol treatment. Women differed from men on measures of treatment affordability, accessibility, acceptability and report of social support, illness severity, comorbidities, and demographic characteristics. Rural women differed from urban women on measures of treatment affordability and accessibility and report of illness severity and comorbidities.

Alcoholism in women: is it different in onset and outcome compared to men?

Onset and course of alcohol dependence show gender related differences (telescoping effect) suggesting that women are more vulnerable to chronic alcohol consumption. This raises the question whether the differences are associated with a different treatment outcome as well. We hypothesized, that alcohol dependent women with a telescoping course show a less favourable treatment outcome compared to men. We investigated 212 alcohol dependent patients; matching 106 consecutively admitted women with 106 men drawn from a total sample of 343 male patients. The treatment program consisted of a 6 week inpatient treatment and 12 months of outpatient aftercare. We assessed milestone variables in development and course of alcoholism and carried out standardized diagnostic tests, physical and blood examinations to evaluate the course of the disease and treatment outcome. Overall, we confirm the telescoping effect, a faster progression in the course of alcoholism (developmental events and adverse consequences) in women compared to men ("telescoping effect"). However, despite the telescoping effect treatment outcome was similar in women and men. During the inpatient treatment program no alcohol relapse occurred. Throughout the 12 months outpatient treatment we found no significant differences in the survival analysis between women (283.29+/-11.26 days) and men (284.72+/-12.16 days). At the end of the 12 months both groups had an abstinence rate of approximately 50% and a drop-out rate of 33%.

Co-occurring psychiatric disorders in women with addictions

There is clinically important comorbidity between psychiatric and substance use disorders, particularly in women. Women with affective and anxiety disorders are more likely to present with alcohol or drug abuse/dependence. In turn, substance-abusing women are more likely to experience clinically significant depression and anxiety. Emerging evidence is pointing to an etiological role for anxiety disorders in the development of substance abuse/dependence; however, etiologic evidence is not as clear-cut for major depressive disorder. PTSD appears to be a particularly important factor for alcohol and drug dependence in women who have experienced childhood or adult sexual and or physical abuse. Although pharmacotherapy for affective or anxiety disorders is useful for ameliorating psychiatric symptoms, research is mixed on the effectiveness for improving alcohol- and drug-related outcomes. There is some limited evidence that women-specific services can improve treatment retention, substance use outcomes, and possibly psychosocial functioning compared with traditional mixed-gender programs. However, it is clear that women with co-occurring psychiatric and substance use problems are challenging to engage and retain in care. Physicians providing women's reproductive health services can serve a vital role in the identification and referral of substance-abusing women. Particular attention should be focused on screening and assessment of alcohol and drug use and problem severity among women who have identified psychiatric disorders or who are receiving antidepressant or anxiolytic medications. Recognition and referral for both psychiatric and substance use disorders are critical for long-term health and psychosocial improvement.

Alcohol-exposed pregnancy: characteristics associated with risk

BACKGROUND

Prenatal alcohol exposure is a leading cause of neurodevelopmental deficits in children. Women who are fertile, drink alcohol, and have unprotected intercourse are at risk for an alcohol-exposed pregnancy, but little is known about this population.

METHODS

A survey was administered to 2672 English-speaking women aged 18 to 44 years from six settings, including an urban jail, a drug/alcohol treatment facility, a gynecology clinic, two primary care clinics, and respondents to a media solicitation. Bivariate and multivariate analyses were conducted to explore variables that were correlated with membership in the at-risk group.

RESULTS

Most respondents (70%) reported a household income of <$20,000; 68% had a high school or equivalent education; and 62% were African American. A total of 333 women (12.5%) met the a priori definition of "at risk" for an alcohol-exposed pregnancy. Stepwise logistic regression showed that recent drug use (odds ratio [OR]=3.1; 95% confidence interval [CI]=2.1-4.4); having smoked more than 100 cigarettes (OR=1.9, 95% CI=1.3-2.7); a history of inpatient treatment for drugs or alcohol (OR=1.8, 95% CI=1.3-2.4) or inpatient mental health treatment (OR=1.6, 95% CI=1.1-2.3); having multiple sex partners (OR=1.7, 95% CI=1.2-2.2); and recent physical abuse (OR=1.5, 95% CI=1.1-2.0) were significantly correlated with being at risk.

CONCLUSIONS

It was possible to identify diverse settings with an increased prevalence of women at risk for an alcohol-exposed pregnancy. Within these settings, women at risk were characterized by an increased frequency of selected behaviors. This information may help clinicians develop and target interventions prior to conception.

Brief interventions for problem drinking and women

Early identification and intervention among problem drinking women may avert the more severe, adverse consequences of alcohol abuse and dependence. Screening and brief interventions, while generally effective, have not been adequately examined among subgroups, such as women. The purpose of this review article is to examine the efficacy of brief interventions for the population of women in need of some alcohol treatment. Representative studies with random assignment to treatment conditions and either substantial numbers of women, or a special focus on women, were included. Findings suggest brief interventions are not consistently helpful to women drinkers.

Alcohol use disorders in primary care: do gender-specific differences exist?

OBJECTIVE

To describe how alcohol use disorders (AUDs) affect women, focusing on gender-specific implications for primary care physicians (PCPs).

DESIGN

An overview of literature from 1966 to 2000 identified by a medline, PsychINFO and HealthSTAR/Ovid Healthstar database search using key words "women,""alcohol" and "alcoholism."

MEASUREMENTS AND MAIN RESULTS

Although the prevalence of AUDs is greater in men than in women, women with AUDs are more likely to seek help, but less likely to be identified by their physicians. Psychiatric comorbidities (especially depression and eating disorders) are more common in women with AUDs than in men with AUDs. A past history of sexual and/or physical abuse places a woman at increased risk for AUDs. Women have a greater sensitivity to alcohol, have an accelerated progression from alcohol toxicity, and have increased mortality at lower levels of consumption compared to men. Women and men who are light-to-moderate drinkers have lower coronary artery disease mortality than do abstainers or heavy drinkers. Risk of breast cancer is increased in women who drink >or=1 drinks daily. Common barriers to treatment include: fear of abandonment by partner; fear of loss of children; and financial dependency. Brief interventions have been shown to be effective in reduction of alcohol consumption in women with at-risk drinking. It is unclear if women-only treatment programs improve outcomes.

CONCLUSION

PCPs should be alert to gender-specific differences for women with AUDs.

Gender differences for the risk of alcohol-related problems in multiple national contexts

The primary research question asked is: After holding alcohol consumption constant, will men and women be at equal risk for a variety of alcohol-related problems? Since women are actually at a higher blood alcohol content at the same consumption levels, a physiological argument would suggest that women are at equal or greater risk for alcohol problems than men. However, variation in societal norms surrounding gender roles and/or societal-level stress may mediate the experience of men and women, regardless of the differences in physiology. Ten cross-sectional general population studies are used. Analyses control for individual-level variables (age, quantity, and frequency of drinking) and societal-level variables (proportion of women in the work force and female suicide rate) that might confound these relationships; cross-study homogeneity is examined.

Medical risks for women who drink alcohol

OBJECTIVE

To summarize for clinicians recent epidemiologic evidence regarding medical risks of alcohol use for women.

METHODS

MEDLINE and PsychINFO, 1990 through 1996, were searched using key words "women" or "woman," and "alcohol." MEDLINE was also searched for other specific topics and authors from 1980 through 1996. Data were extracted and reviewed regarding levels of alcohol consumption associated with mortality, cardiovascular disease, alcohol-related liver disease, injury, osteoporosis, neurologic symptoms, psychiatric comorbidity, fetal alcohol syndrome, spontaneous abortion, infertility, menstrual symptoms, breast cancer, and gynecologic malignancies. Gender-specific data from cohort studies of general population or large clinical samples are primarily reviewed.

MAIN RESULTS

Women develop many alcohol-related medical problems at lower levels of consumption than men, probably reflecting women's lower total body water, gender differences in alcohol metabolism, and effects of alcohol on postmenopausal estrogen levels. Mortality and breast cancer are increased in women who report drinking more than two drinks daily. Higher levels of alcohol consumption by women are associated with increased menstrual symptoms, hypertension, and stroke. Women who drink heavily also appear to have increased infertility and spontaneous abortion. Adverse fetal effects occur after variable amounts of alcohol consumption, making any alcohol use during pregnancy potentially harmful.

CONCLUSIONS

In general, advising nonpregnant women who drink alcohol to have fewer than two drinks daily is strongly supported by the epidemiologic literature, although specific recommendations for a particular woman should depend on her medical history and risk factors.

Gender differences in the brain: implications for the study of human alcoholism

Gender differences in alcohol intake and response to alcohol may be influenced by basic variations in the organization and modulation of male and female brains. Although a number of genetic, social, environmental, and metabolic factors have been proposed to explain the gender differences observed in risk for alcoholism, alcohol intake, and medical consequences of excessive alcohol intake, very little attention has been given to the role of gender differences in the brain regarding alcohol use. Recent evidence documents the influence of neurosteroids on neurotransmitter activity in the brain and the impact of alcohol on neurosteroid levels. Neurosteroids are found in different levels in males and females during development and throughout life, depending on factors such as age, stage of development, estrous and menstrual cycles, and stress. This study discusses the hypothesis that many of the gender differences observed concerning alcohol use and misuse are determined by gender differences in the brain, which in turn differentially influence the behavioral and neurochemical responses of males and females to alcohol.
