"Not getting tanked": definitions of moderate drinking and their health implications.

BACKGROUND: People encounter large amounts of sometimes-inconsistent information about risks and benefits of alcohol consumption, and about what constitutes "low-risk" or "moderate" drinking. METHODS: We used 150 in-depth interviews linked to questionnaire data to learn how people define moderate drinking and to describe the relationships between definitions, attitudes, and beliefs about moderate drinking and individuals' drinking patterns. RESULTS: People adhere to definitions of moderate alcohol consumption that could put them, or others, at risk for short- or long-term negative consequences of drinking. Definitions that confused increased tolerance of alcohol with moderate drinking, and those that defined moderate drinking by the absence of short-term negative consequences or ability to maintain control over drinking, ignore long-term risks of heavy consumption. Individuals with risky attitudes were also more likely to report at-risk drinking practices. CONCLUSIONS: Americans have complex beliefs about benefits and risks of alcohol consumption, and public health officials have not succeeded in conveying strong or clear messages about what constitutes low-risk drinking or about dose-response effects. Different (but more consistent) approaches to public education may be needed to increase knowledge about drinking-related risks. The prevalence of diverse norm-based definitions suggests that alternative normative information could help people reassess their own consumption.

Substance abuse treatment entry, retention, and outcome in women: a review of the literature.

This paper reviews the literature examining characteristics associated with treatment outcome in women with substance use disorders. A search of the English language literature from 1975 to 2005 using Medline and PsycInfo databases found 280 relevant articles. Ninety percent of the studies investigating gender differences in substance abuse treatment outcomes were published since 1990, and of those, over 40% were published since the year 2000. Only 11.8% of these studies were randomized clinical trials. A convergence of evidence suggests that women with substance use disorders are less likely, over the lifetime, to enter treatment compared to their male counterparts. Once in treatment, however, gender is not a significant predictor of treatment retention, completion, or outcome. Gender-specific predictors of outcome do exist, however, and individual characteristics and treatment approaches can differentially affect outcomes by gender. While women-only treatment is not necessarily more effective than mixed-gender treatment, some greater effectiveness has been demonstrated by treatments that address problems more common to substance-abusing women or that are designed for specific subgroups of this population. There is a need to develop and test effective treatments for specific subgroups such as older women with substance use disorders, as well as those with co-occurring substance use and psychiatric disorders such as eating disorders. Future research on effectiveness and cost-effectiveness of gender-specific versus standard treatments, as well as identification of the characteristics of women and men who can benefit from mixed-gender versus single-gender treatments, would advance the field.

What teens want: barriers to seeking care for depression.

This study examined the experiences of teenagers seeking and receiving care for depression from primary care providers. We investigated teens' perceived barriers in obtaining care to determine how primary care can effectively address depressed teens' stated needs. In-depth individual (n = 15) and focus group (n = 7) interviews with adolescents were conducted and analyzed using grounded theory and prominent themes were identified. Teenagers reported faring best when providers actively considered and reflected upon the teenagers' developmentally appropriate desires to be normal, to feel connected, and to be autonomous. These goals are achieved by providers establishing rapport, exchanging information about depression etiology and treatment, and helping teens make decisions about their treatment. To the extent that providers improve efforts to help teens feel normal, autonomous, and connected, the teens report they are more likely to accept treatment for depression and report success in treatment.

Substance abuse treatment duration for Medicaid versus commercial clients in a health maintenance organization.

BACKGROUND: As Medicaid clients have come to be enrolled in managed care, concerns have arisen about the ability of private sector systems to meet the needs of enrollees with substance abuse problems. OBJECTIVES: This project describes treatment initiation and duration for Medicaid and commercial substance abuse treatment clients in a large health maintenance organization (HMO). RESEARCH DESIGN: This study was a prospective secondary analysis of information from HMO databases. Subjects were 641 adult Medicaid clients who contacted the HMO's addiction medicine department in 1996 or 1997 and commercial HMO addiction medicine patients (n=447). First contact with addiction medicine during the study period was the index event. MEASURES: Chief dependent variables were initiation and duration of substance abuse treatment after the index event. RESULTS: Logistic regression showed that longer HMO enrollment predicted treatment initiation after substance abuse assessment, but Medicaid status was not a significant predictor. A competing risks analysis using Cox proportional hazards models indicated that once subjects had initiated, Medicaid was not significantly related to exit from substance abuse treatment. Analysis of health plan disenrollment by Medicaid clients indicated that the most common reason was loss of Medicaid eligibility. CONCLUSIONS: These results raise the possibility that state Medicaid policies may make it difficult for clients to obtain suitable chemical dependency treatment services.

Gender and use of substance abuse treatment services.

Women are more likely than men to face multiple barriers to accessing substance abuse treatment and are less likely to seek treatment. Women also tend to seek care in mental health or primary care settings rather than in specialized treatment programs, which may contribute to poorer treatment outcomes. When gender differences in treatment outcomes are reported, however, women tend to fare better than men. Limited research suggests that gender-specific treatment is no more effective than mixed-gender treatment, though certain women may only seek treatment in women-only programs. Future health services research should consider or develop methods for (1) improving care for women who seek help in primary care or mental health settings, (2) increasing the referral of women to specialized addiction treatment, (3) identifying subgroups of women and men who would benefit from gender-specific interventions, and (4) addressing gender-specific risk factors for reduced treatment initiation, continuation, and treatment outcomes.

Behavioral counseling interventions in primary care to reduce risky/harmful alcohol use by adults: a summary of the evidence for the U.S. Preventive Services Task Force.

BACKGROUND: Primary health care visits offer opportunities to identify and intervene with risky or harmful drinkers to reduce alcohol consumption. PURPOSE: To systematically review evidence for the efficacy of brief behavioral counseling interventions in primary care settings to reduce risky and harmful alcohol consumption. DATA SOURCES: Cochrane Database of Systematic Reviews, Database of Research Effectiveness (DARE), MEDLINE, Cochrane Controlled Clinical Trials, PsycINFO, HealthSTAR, CINAHL databases, bibliographies of reviews and included trials from 1994 through April 2002; update search through February 2003. STUDY SELECTION: An inclusive search strategy (alcohol* or drink*) identified English-language systematic reviews or trials of primary care interventions to reduce risky/harmful alcohol use. Twelve controlled trials with general adult patients met our quality and relevance inclusion criteria. DATA EXTRACTION: Investigators abstracted study design and setting, participant characteristics, screening and assessment procedures, intervention components, alcohol consumption and other outcomes, and quality-related study details. DATA SYNTHESIS: Six to 12 months after good-quality, brief, multicontact behavioral counseling interventions (those with up to 15 minutes of initial contact and at least 1 follow-up), participants reduced the average number of drinks per week by 13% to 34% more than controls did, and the proportion of participants drinking at moderate or safe levels was 10% to 19% greater compared with controls. One study reported maintenance of improved drinking patterns for 48 months. CONCLUSIONS: Behavioral counseling interventions for risky/harmful alcohol use among adult primary care patients could provide an effective component of a public health approach to reducing risky/harmful alcohol use. Future research should focus on implementation strategies to facilitate adoption of these practices into routine health care.

Gender differences in the relationships between multiple measures of alcohol consumption and physical and mental health.

BACKGROUND: Epidemiological research examining health consequences of alcohol consumption generally relies on average volume consumed, yet examinations of drinking patterns show different dimensions of use associated with different health outcomes. Gender differences in metabolism and body composition may lead to gender-specific consequences of drinking frequency, quantity consumed per occasion, average amount consumed, and drinking pattern. Inconsistent results suggest gender differences are not well understood. METHODS: Participants were 3069 male and 2600 female health maintenance organization survey respondents. Gender differences in relationships between alcohol consumption and health were examined using analyses of covariance adjusting for age alone and for age, ethnicity, marital status, body water index, and smoking. Past-year alcohol consumption (frequency, quantity per occasion, average drinks per month, and drinking pattern) and health measures (Short Form-36 general health, physical functioning, mental health subscales) were examined. RESULTS: Gender x drinking frequency and drinking quantity interactions were significant in age-adjusted and fully adjusted models of general health and physical functioning. Gender interactions for drinking pattern were significant in the age-adjusted model and marginally significant in the fully adjusted model. No gender x drinking measure interactions were found for mental health. Fully adjusted models attenuated but did not eliminate gender differences for health and magnified relationships for functioning, the latter after adjusting for body water. For both genders, light to moderate consumption and more frequent drinking were associated with better health and functioning; relationships were stronger among women than men. CONCLUSIONS: Gender x drinking measure interactions in health outcomes suggest analyses should include such interactions except, possibly, for mental health. Adjusting for potential confounders can attenuate (general health) or magnify (physical functioning) gender differences. Functional status appears a sensitive measure for evaluating gender differences in alcohol's health effects, adjusting for body water. Women's health may benefit proportionally more from moderate drinking than men's.

"Being in a funk": teens' efforts to understand their depressive experiences.

Although there is literature about adults' experiences of depression, little research has focused on teenagers' experiences. In this article, the authors describe how a sample of adolescents makes sense of depression and responds to a depression diagnosis. Twenty-two adolescents participated in in-depth individual or focus group interviews. Teens discussed their experiences with depression and getting health care for depression, and described a trajectory similar to that found among adults: a slow growth of distress, a time of being in a funk, and a time of consideration of whether they are depressed. Teens who received a diagnosis from a medical provider then sought to make sense of their depression. Teens understood a depression diagnosis as a helpful label, a chronic medical problem, or a significant part of their identity. Understanding the subjective experience of adolescents who are depressed might increase health care providers'empathy and improve their communication with teens.

Gender differences in outcomes in an HMO-based substance abuse treatment program.

This study examined gender differences in treatment outcomes and outcomes predictors among 155 men and 81 women attending a gender-sensitive substance abuse treatment program. Bivariate analyses indicated women improved more than men in social/family and daily functioning domains, but differences disappeared after controlling for baseline characteristics. Multivariate models predicting treatment outcomes revealed that, across Addiction Severity Index domains, outcomes for men were predicted primarily by mental health and medical conditions, severity of the substance abuse problem, and treatment com- pletion. For women, in addition to treatment completion, outcomes were more likely to be predicted by social, socio-demographic, and life-history characteristics. For abstinence outcomes, women who completed treatment were 9 times as likely to be abstinent at 7-month follow-up as other women; men who completed were 3 times more likely to be abstinent than other men. Women with more severe psychiatric status and those who felt their life was out of control were less likely to be abstinent, as were men who lived alone. Clinicians targeting such factors differentially for men and women may enhance the effectiveness of treatment.

Gender-based structural models of health care costs: alcohol use, physical health, mental health, and functioning.

BACKGROUND: Most models of health services use or costs include gender as a covariate, combining data for men and women in analyses. This strategy may obscure differences in underlying processes producing differential health care use by men and women, particularly in examinations of factors that affect health care use and differ by gender (e.g. alcohol consumption and depression). AIMS: To examine gender differences in the relationships between alcohol consumption, physical and mental health and functioning, and costs of health care. METHODS: The setting was Kaiser Permanente Northwest, a large non-profit group practice model HMO serving northwest Oregon and southwest Washington in the northwest United States. Primary (survey) and secondary (health plan records of service use; diagnoses from medical chart review) data were collected for random samples of health plan members in the period 1989-1993 (n = 5,669). Health plan administrative records of service use were used to estimate health care costs. Gender-specific latent structure models predicting health care costs were created using self-reported mental health, physical health, functioning, alcohol consumption, and prior-year health plan record-based diagnoses of depression and alcohol problems. RESULTS: Alcohol consumption and prior alcohol problems were directly related to health care costs, although in opposite directions, for both men and women. Alcohol consumption was negatively associated with costs, while prior alcohol problems predicted higher costs. Gender differences existed in the relationship between physical health and health care costs indirectly via drinking status. Prior depression had direct effects on increased health care costs, and this relationship was stronger for men than for women. The roles played by mental health symptoms were similar for men and women. Better mental health at the time of the survey was associated with reduced alcohol consumption or likelihood of consuming alcohol, but had no direct effects on later costs. Indirect effects of mental health were found via alcohol consumption. CONCLUSIONS: Gender plays an important role in the factors underlying total costs of health care, and gender differences in these relationships appear more common among those who consume alcohol. For both genders, alcohol use predicts lower health care costs in this light-to-moderate drinking population, although prior diagnoses of alcohol problems predict higher costs. The direct relationship between depression diagnosis and higher health care costs is stronger among men.

Structural models of gender, alcohol consumption, and health.

BACKGROUND: Gender differences exist in patterns of alcohol consumption and in the health and social effects of alcohol use, but little is known about gender differences in how alcohol use is affected by mental and physical health conditions. METHODS: We used structural equation modeling techniques to examine gender differences in the relationships among alcohol consumption, physical and mental health, functional status, and social and demographic characteristics. Data were obtained from a random sample of the adult membership of a health maintenance organization in the U.S. Pacific Northwest. Simultaneous models evaluated gender differences in predictors of drinking vs. nondrinking status and, among drinkers, amount of alcohol consumed. RESULTS: Physical health was twice as strong a predictor of drinker/nondrinker status among women compared with men, but among drinkers, there were no gender differences in predictors of amount of alcohol consumed. Mental health predicted drinking status and alcohol consumption among drinkers, but these relationships did not differ by gender. Overall, sociodemographic characteristics and physical health were stronger predictors of alcohol use among women than among men. CONCLUSIONS: Women may be more amenable than men to alcohol-related preventive messages that target physical health concerns. Treating mental health conditions may be an important method for reducing alcohol consumption.

Community-based care and risk of nursing home placement.

OBJECTIVE: To test the substitution hypothesis, that community-based care reduces the probability of institutional placement for at-risk elderly. RESEARCH DESIGN: The closure of the Social Health Maintenance Organization (Social HMO) at HealthPartners (HP) in Minnesota in 1994 and the continuation of the Social HMO at Kaiser Permanente Northwest (KPNW) in Oregon/Washington comprised a "natural experiment." Using multinomial logistic regression analyses, we followed cohorts of Social HMO enrollees for up to 5 years, 1995 to 1999. To adjust for site effects and secular trends, we also followed age- and gender-matched Medicare-Tax Equity and Fiscal Responsibility Act (TEFRA) cohorts, enrolled in the same HMOs but not in the Social HMOs. SUBJECTS: All enrollees in the Social HMO for at least 4 months in 1993 and an age-gender matched sample of Medicare-TEFRA enrollees. To be included, individuals had to be alive and have a period out of an institution after January 1, 1995 (total n = 18,143). MEASURES: The primary data sources were the electronic databases at HP and KPNW. The main outcomes were long-term nursing home placement (90+ days) or mortality. Covariates were age, gender, a comorbidity index, and geographic site effect. RESULTS: Adjusting for variations in the 2 sites, we found no difference in probability of mortality between the 2 cohorts, but approximately a 40% increase in long-term institutional placement associated with the termination of the Social HMO at HealthPartners (odds ratio, 1.43; 95% confidence interval, 1.15-1.79). CONCLUSIONS: The Social HMO appears to help at-risk elderly postpone long-term nursing home placement.

Gender differences in predictors of initiation, retention, and completion in an HMO-based substance abuse treatment program.

We studied gender differences in treatment process indicators among 293 HMO members recommended for substance abuse treatment. Treatment initiation, completion, and time spent in treatment did not differ by gender, but factors predicting these outcomes differed markedly. Initiation was predicted in women by alcohol diagnoses; in men, by being employed or married. Failure to initiate treatment was predicted in women by mental health diagnoses; in men, by less education. Treatment completion was predicted in women by higher income and legal/agency referral; in men, by older age. Failure to complete was predicted in women by more dependence diagnoses and higher Addiction Severity Index Employment scores; in men, by worse psychiatric status, receiving Medicaid, and motivation for entering treatment. More time spent in treatment was predicted, in women, by alcohol or opiate diagnoses and legal/agency referral; in men, by fewer mental health diagnoses, higher education, domestic violence victim status, and prior 12-step attendance. Clinical implications of results are discussed.

Adapting to psychiatric disability and needs for home- and community-based care.

The objective of the study was to describe adaptation strategies and use of formal and informal support by individuals with psychiatric disabilities, to delineate remaining needs, and to determine how home- and community-based services might address those needs. Using in-depth interviews and structured questionnaires, we examined functional status, adaptation, and needs for home- and community-based care among 33 severely mentally ill members of a large health maintenance organization. Despite success in community living, participants had significant functional deficits (physical and emotional), relied heavily on only one or two key informal caregivers, and often needed significant support from mental health professionals. Limited numbers of caregivers and social isolation placed participants at risk of negative outcomes if informal support resources were to be lost. Home- and community-based care interventions that attempt to increase informal support networks and provide instrumental help (cooking, cleaning, transport) on short notice during flare-ups could augment existing (but limited) informal caregiving, help severely mentally ill individuals remain independent, and reduce the likelihood that loss of an informal caregiver would result in unwanted outcomes.

Depression, functional status, treatment for psychiatric problems, and the health-related practices of elderly HMO members.

PURPOSE: To study relationships between depression, functional limitations, psychiatric treatment, and the health-related practices of elderly individuals. DESIGN: Cross-sectional, observational study based on survey data (response rate = 90%) analyzed using multiple linear and logistic regression models. SETTING: Kaiser Permanente Northwest, a large nonprofit HMO. SUBJECTS: Medicare members (4615) aged 65-103 years who responded to a health status survey. MEASURES: Depression, health and functional status, frequency of alcohol consumption, smoking status, advance medical directive completion, influenza or pneumonia vaccinations, mammograms, recent psychiatric treatment, and attempts to lose weight or increase exercise. RESULTS: Self-reported depression was related to a greater risk of smoking (odds ratio [OR] = 1.54). Health-related functional limitations were related to fewer attempts to change health behaviors and less preventive service use (significant ORs ranged from 0.84 to 0.94). Minority group membership and Supplemental Security Income were negatively associated with better health practices and with completing advance medical directives (ORs 0.41 and 0.79, respectively). Falls in the prior year, more prescription medications, and psychiatric treatment were positively associated with better health practices (significant ORs ranged from 1.12 to 1.88). CONCLUSIONS: Depression and smoking are associated among elderly individuals, as are psychiatric treatment and attempts to lose weight. Those with functional limitations, minority status, or Supplemental Security Income use fewer preventive services; the latter two groups are less likely to complete advance medical directives. Older adults with these characteristics might need assistance in improving health-related practices.
