The "Yes, I Quit" smoking cessation course: does it help women in a low income community quit?

Reducing Disparities in Hypertension Control: A Community-Based Hypertension Control Project (CHIP) for an Ethnically Diverse Population

The Community Hypertension Intervention Project (CHIP) is investigating medical, environmental, and psychosocial factors related to adherence to treatment for hypertension and examining the efficacy of three interventions designed to improve treatment adherence in a high-risk, underserved, ethnically diverse population. There were 1,367 Black (76%) and Hispanic (21%) adults who participated in a 4-year longitudinal study. Participants were randomized to either usual care or one of three interventions: (a) individualized counseling sessions with community health workers (CHWs), (b) a computerized appointment tracking system, or (c) home visits/focus group discussions with CHWs. At baseline, a total of 33% of the participants had one or more comorbidities in addition to hypertension; only 35% had their blood pressure under control. Participants assigned to the patient tracking intervention exhibited the most significant improvement in appointment keeping and blood pressure control status at 6 months; however, the 12-month follow-up assessments indicated that individualized counseling and home visits resulted in significant, sustained improvements in appointment keeping and blood pressure control status. These findings are now being integrated into the patient care delivery system of the participating outpatient clinics.

Motivational interviewing and smoking behaviors: a critical appraisal and literature review of selected cessation initiatives

The present paper systematically reviewed and critically appraised three different dimensions of motivational interviewing currently utilized in smoking cessation initiatives: social support, motivation, and tailored interventions. A review of four databases generated 57 primary articles, 17 of which met the inclusion criteria of an intervention study utilizing at least one dimension of motivational interviewing, adults between 18 and 64 years, no comorbidities, and a follow-up period of at least 6 weeks. More than 11,600 participants are represented in this review. The implementation of social support, motivation, and tailored interventions yielded mixed results. Furthermore, threats to validity emerged, including self-report, follow-up period, sample sizes, a priori differences in groups, and web-based and text-based interventions. Further research must ascertain the efficacy of the three dimensions of motivational interviewing indicated by the mixed results reported in terms of statistical significance of cessation rates. More empirically rigorous designs with evaluations based on stringent replicable criteria are needed.

Targeting those in need: baseline data from the first English National Health Service (NHS) health trainer service

As part of a wider strategy to reduce health inequalities, England's National Health Service has introduced health trainers (HTs) to facilitate healthier behaviour among disadvantaged groups. This study reports baseline data from the first English HT service: assessing whether the HTs reached socially disadvantaged clients engaging in unhealthy behaviours and describing client belief characteristics relevant to the delivery of the service. Data from 864 clients show that the service reached disadvantaged groups and that those groups were engaging in risky health behaviours. Self-efficacy about changing behaviour was not strong and clients were unlikely to have made explicit behaviour-change plans prior to attending the service. Implications for HT services around targeting those most in need and supporting psychological triggers for change are discussed.

Nicotine dependence, psychological distress and personality traits as possible predictors of smoking cessation. Results of a double-blind study with nicotine patch

AIM

Nicotine replacement therapy (NRT) is an effective treatment for smokers who want to quit, however, the rates of successful quitting can be improved even more. In this context, nicotine dependence (assessed via the Fagerström Tolerance Questionnaire, FTQ), psychological distress (measured via the Symptom Rating Test, SRT), and personality traits (evaluated via the Adult Eysenck Personality Inventory, AEPI) were evaluated as possible predictors of smoking cessation.

RESULTS

A total of 297 cigarette smokers were followed for one year as part of a NRT double-blind, parallel group, randomized trial. Baseline nicotine dependence (weeks 12 and 26: p<0.05), AEPI neuroticism (weeks 12 and 52: p<0.05), and AEPI psychoticism (weeks 12 and 52: p<0.05) scores significantly influenced the outcome of smoking cessation during one-year of follow-up. An increase in psychological distress during follow-up was associated with a lower probability of quitting smoking (p=0.000).

CONCLUSIONS

Nicotine dependence, neuroticism, psychoticism and, over time, psychological distress were the main factors influencing the long-term outcome (i.e., up to 12 months) of smoking cessation under NRT.

Predictors of quitting among African American light smokers enrolled in a randomized, placebo-controlled trial

OBJECTIVE

To examine the predictors of quitting among African American (AA) light smokers (<10 cigarettes per day) enrolled in a smoking cessation trial.

METHODS

Baseline variables were analyzed as potential predictors from a 2 x 2 cessation trial in which participants were randomly assigned to 1 of 4 treatment groups: nicotine gum plus health education (HE) counseling, nicotine gum plus motivational interviewing (MI) counseling, placebo gum plus HE counseling, or placebo gum plus MI counseling. Chi-square tests, 2 sample t-tests, and multiple logistic regression analyses were used to identify predictors of cotinine (COT) verified abstinence at month 6.

RESULTS

In the final regression model, HE rather than MI counseling (odds ratio [OR]=2.26%, 95% confidence interval [CI]=1.36 to 3.74), older age (OR=1.03%, 95% CI=1.01 to 1.06), and higher body mass index (OR=1.04%, 95% CI=1.01 to 1.07) significantly increased the likelihood of quitting, while female gender (OR=0.46%, 95% CI=0.28 to 0.76),</=$1,800/month income (OR=0.60%, 95% CI=0.37 to 0.97), higher baseline COT (OR=0.948%, 95% CI=0.946 to 0.950), and not completing all counseling sessions (OR=0.48%, 95% CI=0.27 to 0.84) reduced the odds of quitting.

CONCLUSIONS

Individual characteristics may decrease the likelihood of quitting; however, the provision of directive, advice-oriented counseling focused on the addictive nature of nicotine, health consequences of smoking, benefits of quitting, and development of a concrete quit plan may be an important and effective facilitator of quitting among AA light smokers.

Socioeconomic disadvantage, parenting responsibility, and women's smoking in the United States

OBJECTIVES

We carried out analyses of smoking in relation to poverty and child care responsibility among women aged 18-54 years residing in the United States.

METHODS

With data from the Behavioral Risk Factor Surveillance System, we assessed the interaction effects of poverty and living with young children on maternal smoking behavior among 61,700 women aged 18-54 years in 4 different racial/ethnic groups.

RESULTS

For non-White racial/ethnic groups, the prevalence of smoking among women with small children in the household was lower than that among women without small children. However, White women were more likely to smoke if they were poor and living with small children (odds ratio=1.14, 95% confidence interval=1.03, 1.26).

CONCLUSIONS

These results suggest that child care responsibility confers an increased risk of smoking among low-income White women.

Predictors of 6-month tobacco abstinence among 1224 cigarette smokers treated for nicotine dependence

This study examined baseline characteristics associated with abstinence from tobacco 6 months after treatment for nicotine dependence. A total of 1224 cigarette smokers (619 females, 605 males) receiving clinical services for treatment of nicotine dependence between January 1, 1995 and June 30, 1997 were studied. The intervention involves a 45-min consultation with a nicotine dependence counselor. A treatment plan individualized to the patient's needs is then developed. The main outcome measure was the self-reported 7-day point prevalence abstinence from tobacco obtained by telephone interview 6-months after the consultation. A bootstrap resampling methodology for predictor variable selection was used to identify a set of multivariate predictors of 6-month tobacco abstinence. Five variables were multivariately associated with tobacco abstinence: male gender, no current psychiatric diagnosis, higher stage of change, longest duration of previous abstinence from tobacco of <1 or > or =30 days, and Fagerström Test for Nicotine Dependence (FTND) score of < or =5. Assessment of these variables may be useful clinically by assisting health care providers in tailoring nicotine dependence interventions to enhance outcomes.

Examination of the temporal relationship between smoking and major depressive disorder among low-income women in public primary care clinics

PURPOSE

To determine the prevalence of major depressive disorder (MDD) by smoking status, and the temporal relationship between smoking and MDD, and explore other smoking-related variables that may be associated with MDD.

DESIGN

Cross-sectional study.

SETTING

Public primary care clinics.

SUBJECTS

Researchers studied 338 women (76% African-Americans) who were randomly selected while attending appointments in two public primary care clinics.

MEASURES

Data pertaining to smoking-related variables and MDD diagnosis were obtained using the Diagnostic Interview Schedule for the Diagnostic Statistical Manual of Mental Disorder IV (DSM-IV).

RESULTS

The prevalence of a lifetime history of MDD was significantly higher for current smokers (56.6%) than among former smokers (37.5%) or never-smokers (30.3%; p < .001). Most ever-smokers (81.3%) began smoking and were nicotine-dependent (63.6%) prior to their first episode of MDD. Using logistic regression, after controlling for demographic and smoking-related variables, age of smoking onset was the strongest variable associated with MDD among ever-smokers. Specifically, the odds of having an MDD decreased by 8.2% for each year delay in smoking initiation.

CONCLUSION

These results suggest that smoking initiation precedes MDD and that smoking is associated with a high prevalence of MDD among low-income women attending primary care clinics. Further, the younger women start smoking the more likely they are to have MDD.

Community interventions for reducing smoking among adults

BACKGROUND

Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking.

OBJECTIVES

To assess the effectiveness of community interventions for reducing the prevalence of smoking.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group specialised register, MEDLINE (1966-August 2001) and EMBASE (1980-August 2001) and reference lists of articles.

SELECTION CRITERIA

Controlled trials of community interventions for reducing smoking prevalence in adult smokers. The primary outcome was smoking behaviour.

DATA COLLECTION AND ANALYSIS

Data were extracted by one person and checked by a second.

MAIN RESULTS

Thirty two studies were included, of which seventeen included only one intervention and one comparison community. Only four studies used random assignment of communities to either the intervention or comparison group. The population size of the communities ranged from a few thousand to over 100,000 people. Change in smoking prevalence was measured using cross-sectional follow-up data in 27 studies. The estimated net decline ranged from -1.0% to 3.0% for men and women combined (10 studies). For women, the decline ranged from -0.2% to + 3.5% per year (n=11), and for men the decline ranged from -0.4% to +1.6% per year (n=12). Cigarette consumption and quit rates were only reported in a small number of studies. The two most rigorous studies showed limited evidence of an effect on prevalence. In the US COMMIT study there was no differential decline in prevalence between intervention and control communities, and there was no significant difference in the quit rates of heavier smokers who were the target intervention group. In the Australian CART study there was a significantly greater quit rate for men but not women.

REVIEWER'S CONCLUSIONS

The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.

A clinic and community-based approach to hypertension control for an underserved minority population: design and methods

This paper describes the design and methodology of the Community Hypertension Intervention Project (CHIP). CHIP is investigating the environmental and psychosocial factors related to treatment adherence and examining the effects of combining usual hypertension care with the effects of three interventions designed to improve patient compliance with treatment for high blood pressure in a high-risk, underserved minority population. Thirteen hundred and sixty-seven inner-city hypertension patients (75% black and 25% Hispanic) have agreed to participate in the 4-year longitudinal study. These participants were randomized to usual care or one of three intervention groups: individualized counseling sessions; home visits/discussion groups; or computerized appointment-tracking system. Participants are representative of the surrounding, predominantly low-income minority community and are treated in a hospital-based clinic and in a private clinic in the community. About 65% have blood pressure levels considered to be out of control. It was concluded that structural changes at the clinic site, along with the targeted interventions, would improve patient satisfaction, increase treatment adherence, and improve blood pressure control.

The impact of a community-based heart disease prevention program in a low-income, inner-city neighborhood

OBJECTIVES

This study evaluated the impact of a 4-year, community-based cardiovascular disease prevention program among adults aged 18 to 65 years living in St-Henri, a low-income, innercity neighborhood in Montreal, Quebec.

METHODS

Awareness of and participation in the program were monitored in 3 independent sample telephone surveys. Self-reported behaviors were compared in St-Henri and a nearby comparison community before and after program implementation in both a 3-year repeat independent sample survey and a 5-year longitudinal cohort telephone survey.

RESULTS

Awareness of the program reached 37.4%, but participation was low (2%-3%). There were no secular declines in smoking or high-fat diet; physical inactivity increased in both communities. There were no statistically significant program effects detected in the independent sample surveys, although physical inactivity increased more in the comparison community than in St-Henri. In the longitudinal cohort sample, there was a small, statistically significant increase favoring St-Henri in frequency of cholesterol checkups.

CONCLUSIONS

Despite careful adaptation of the program to the local social context, there were few community-wide program effects. However, several component interventions showed promise in terms of community penetration and impact.
