Tobacco use, problem drinking, and alcoholism

Cigarette smoking, nicotine dependence, and motivation for smoking cessation in psychiatric inpatients

OBJECTIVE

Cigarette smoking is the leading preventable cause of death and disease in Canada, and is disproportionately more frequent among psychiatric patients. Smoking cessation interventions can be successfully implemented with psychiatric patients, yet no Canadian studies have evaluated smoking prevalence, nicotine dependence, and motivation for smoking cessation in psychiatric inpatients. Our study did so to help plan appropriate interventions for these patients.

METHOD

All inpatients aged 18 years or older admitted to acute-care psychiatry units at the Foothills Medical Centre in Calgary, Alberta, during a 6-month period completed a survey involving questions from the Canadian Tobacco Use Monitoring Survey, the Fagerstrom Test for Nicotine Dependence (FTND), the Readiness to Quit Ladder, and the Decisional Balance for Cigarette Smoking. Responses were analyzed for correlation with discharge diagnoses, age, and sex.

RESULTS

Among the total inpatients (n = 342), 211 (62%) completed the survey. Among those, 55% were current cigarette smokers and 17.5% were former smokers. Nicotine dependence (FTND > or = 6) was reported in 45.2% of smokers. Smoking prevalence and nicotine dependence severity was greatest in the substance use disorders (SUD) and psychotic disorders groups. Current smokers endorsed more negative than positive attributes of smoking. Regarding smoking cessation, 51% of patients were precontemplative, 12.7% contemplative, and 36.2% preparatory or action-oriented, despite few receiving advice to quit.

CONCLUSIONS

Cigarette smoking and nicotine dependence are highly prevalent in psychiatric inpatients. However, self-reported motivation for smoking cessation is noteworthy, emphasizing that cessation advice and appropriate follow-up care should be provided to psychiatric inpatients who smoke.

Exploring pregnancy-related changes in alcohol consumption between black and white women

BACKGROUND

Although epidemiological data indicate that White women are more likely to drink and binge drink before pregnancy, fetal alcohol syndrome (FAS) is more common in the Black population than among Whites in the United States. Differences in drinking cessation between Black and White women who become pregnant may help explain the disparity in FAS rates.

METHODS

The study sample was comprised of 280,126 non-Hispanic Black and White women, ages 18 to 44, from the Behavioral Risk Factor Surveillance System (BRFSS) 2001 to 2005 data sets. Predictors of reduction in alcohol consumption (in drinks per month) and binge drinking (>4 drinks on one occasion) by pregnant and non-pregnant women were identified with logistic regression. The effect of interactions of pregnancy status with age, education, and Black or White race on drinks per month and binge occasions were explored using analysis of variance (ANOVA).

RESULTS

Pregnant White women averaged 79.5% fewer drinks per month than non-pregnant White women (F = 1250.1, p < 0.001), and 85.4% fewer binge drinking occasions (F = 376, p < 0.001). Pregnant Black women averaged 58.2% fewer drinks per month than non-pregnant Black women (F = 31.8, p < 0.001) and 64.0% fewer binge occasions (F = 13.8, p < 0.001). Compared to Black women, White women appear to make a 38% greater reduction in drinks per month, and a 33% greater reduction in binge occasions.

CONCLUSIONS

Non-Hispanic White women appear more likely to reduce drinks per month and binge drinking occasions than non-Hispanic Black women during pregnancy. These findings may help explain disparities in FAS in the United States, though this cross-sectional sample does not permit claims of causation. To better describe the impact of differential drinking reduction on FAS rates, future studies of longitudinal data should be done.

Substance abuse treatment for mothers: treatment outcomes and the impact of length of stay

This article examines the treatment outcomes of 305 women enrolled in a comprehensive, residential substance abuse treatment program for pregnant and parenting women and their children. The women were assessed at intake and three times in the year after discharge. Analyses focused on change in client functioning over time, and investigating the impact of length of stay in treatment on client outcomes. Comparisons of clients' functioning before and after treatment suggest significant improvements in a number of domains, including substance use, employment, legal involvement, mental health, parenting attitudes, and risky behaviors. For most outcome domains, results suggest that longer treatment stays are associated with more positive outcomes.

Nicotine dependence, depression, and gender: characterizing phenotypes based on withdrawal discomfort, response to smoking, and ability to abstain

Smoking is often viewed as a comprehensive phenotype rather than a complex set of traits involving intermediate phenotypes. To explore this issue in a laboratory setting, we tested 69 smokers stratified on depression, nicotine dependence, and gender. On the third day of an initial withdrawal period, we tested for differences among participants in uncued and cued craving and withdrawal; on the fourth day, we exposed them to a controlled dose of smoke and assessed them for physiological and hedonic effects and reduction of craving and withdrawal. Following resumption of smoking for at least a week, we then tested participants on their ability to abstain for an 11-day interval. During the withdrawal test, high-depressed smokers and men exhibited elevated craving and withdrawal scores overall, whereas no differences emerged for dependence. Cue exposure produced significant increases in craving but not withdrawal. During the smoke-exposure test, men were significantly more likely than women, and high-depressed smokers more likely than low-depressed smokers, to show evidence of experiencing pleasurable "buzzes." High-dependent smokers showed significant increases in diastolic blood pressure, possibly suggestive of greater sensitivity to nicotine. During the quit test, high-dependent smokers had more difficulty abstaining than low-dependent smokers, and women more than men; no differences emerged based on depression. Independently of group membership, inability to abstain was predicted by increased anxiety, depression, and difficulty concentrating in response to cue exposure. These findings provide support for the existence of phenotypes that can be distinguished by withdrawal symptomatology (primarily driven by depression) and ability to remain abstinent (primarily driven by dependence).

Labor analgesia for the tobacco and ethanol abusing pregnant patient: a routine management?

INTRODUCTION

Illicit substance use in pregnancy has received significant media attention over the past 25 years. However, far too little attention has been given to the consequences of the use/misuse of social drugs such as tobacco and ethanol, which are by far the most commonly used/misused substances in pregnancy.

DISCUSSION

While the deleterious effects of amphetamines or cocaine on the mother and the fetus are more pronounced and easier to detect, the addiction to tobacco and ethanol is usually subtle and more difficult to diagnose. As a result, recreational use of tobacco and alcohol in pregnancy may continue undetected, significantly impacting pregnancy outcome and the peripartum management of these patients.

Specific roles of the obstetrician-gynecologist

Obstetrician-gynecologists can play a major role in the prevention, identification, and treatment of substance abuse in women. Maintaining cognizance of abuse potential and consistently using office-screening techniques will identify patients who need assistance. Employing brief interventions at frequent office visits is an effective means of treating many of these patients. Those who do not respond to brief interventions may benefit from referral to an addictionologist. The US Supreme Court recently verified the Fourth Amendment rights of pregnant women by deciding that consent must be obtained to perform drug screening in pregnancy. Obstetrician-gynecologists will need to stay abreast of the changes that occur in their state laws as a result of this decision.
