Successes and failures of the teachable moment: Smoking cessation in cancer patients

Successful cancer treatment can be significantly compromised by continued tobacco use. Because motivation and interest in smoking cessation increase after cancer diagnosis, a window of opportunity exists during which healthcare providers can intervene and assist in the quitting process.

Smoking behavior in a low-income multiethnic HIV/AIDS population

The aim of this study was to describe smoking prevalence and smoking behavior in a multiethnic low-income HIV/AIDS population. A cross-sectional survey design was used. The study site was Thomas Street Clinic, an HIV/AIDS care facility serving a medically indigent and ethnically diverse population. Demographic, disease status, behavioral, and psychosocial variables were assessed by participant self-report. Surveys were collected from 348 study participants. Demographic composition of the sample was 78% male, 25% White, 44% Black, and 29% Hispanic. Study participants had a mean age of 40.2 years (SD=7.8). The HIV exposure profile of the sample was diverse: 46% men who have sex with men, 35% heterosexual contact, and 11% injection drug use. Prevalence of current cigarette smoking in the sample was 46.9%. Among participants with a lifetime history of smoking 100 or more cigarettes (62.8%), only 26.6% were currently abstinent, lower than the 48.8% rate seen in the general population. Multiple logistic regression analysis indicated that race/ethnicity, education level, age, and heavy drinking were significantly associated with smoking status. Hispanics were less likely than Whites were to smoke, younger participants were less likely than older participants were to be current smokers, and heavy drinkers were more likely to be current smokers than were those who were not heavy drinkers. As education level increased, the likelihood of smoking decreased and the likelihood of quitting increased. The high smoking prevalence in this HIV/AIDS population demonstrates the need for smoking cessation interventions targeted to the special needs of this patient group.

A randomized trial of a proactive cellular telephone intervention for smokers living with HIV/AIDS

Objective:To assess the efficacy of an innovative smoking cessation intervention targeted to a multiethnic, economically disadvantaged HIV-positive population. Design:A two-group randomized clinical trial compared a smoking cessation intervention delivered by cellular telephone with usual care approach. Methods:Current smokers from a large, inner city HIV/AIDS care center were recruited and randomized to receive either usual care or a cellular telephone intervention. The usual care group received brief physician advice to quit smoking, targeted self-help written materials and nicotine replacement therapy. The cellular telephone intervention received eight counseling sessions delivered via cellular telephone in addition to the usual care components. Smoking-related outcomes were assessed at a 3-month follow-up. Results:The trial had 95 participants and 77 (81.0%) completed the 3-month follow-up assessment. Analyses indicated biochemically verified point prevalence smoking abstinence rates of 10.3% for the usual care group and 36.8% for the cellular telephone group; participants who received the cellular telephone intervention were 3.6 times (95% confidence interval, 1.3-9.9) more likely to quit smoking compared with participants who received usual care (P = 0.0059). Conclusions:These results suggest that individuals living with HIV/AIDS are receptive to, and can be helped by, smoking cessation treatment. In addition, smoking cessation treatment tailored to the special needs of individuals living with HIV/AIDS, such as counseling delivered by cellular telephone, can significantly increase smoking abstinence rates over that achieved by usual care.

Efficacy of cell phone-delivered smoking cessation counseling for persons living with HIV/AIDS: 3-month outcomes

INTRODUCTION Substantial evidence indicates that cigarette smoking among people living with HIV/AIDS (PLWHA) represents a significant public health concern. However, few efforts to assess smoking cessation interventions targeting this population have been reported. In this brief report, 3-month outcomes from an ongoing treatment trial for PLWHA who smoke are described. METHODS Study participants were recruited from a large HIV care center serving a diverse population of PLWHA. A two-group randomized design was used to compare the efficacy of usual-care (UC) smoking cessation treatment versus a cell phone intervention (CPI). Follow-ups were conducted at the HIV clinic 3 months postenrollment. Using an intent-to-treat approach, a series of multiple regression models were used to compare smoking outcomes in the 2 groups. RESULTS Four hundred and seventy-four participants were enrolled and randomized, UC (n = 238) and CPI (n = 236). Mean age in the sample was 44.8 (SD = 8.1) years, and the majority were male (70.0%), Black (76.6%), and had an education level of high school or less (77.5%). At follow-up, participants in the CPI group were 4.3 (95% CI = 1.9, 9.8) times more likely to be abstinent (7 day) compared with those in the UC group. Similarly, significant point estimates were observed for the other smoking outcomes of interest. CONCLUSIONS Findings from this preliminary report indicate that a smoking cessation intervention for PLWHA consisting of cell phone-delivered proactive counseling results in significantly higher abstinence rates compared with a standard care approach. Evaluation of the long-term (6-month and 12-month) efficacy of the CPI approach is ongoing.

Smoking Relapse during the First Year after Treatment for Early-Stage Non–Small-Cell Lung Cancer

Background: Non–small-cell lung cancer patients who continue to smoke after cancer diagnosis are more likely to experience disease recurrence, decreased treatment efficacy, and treatment complications. Despite this, many continue to smoke, with estimates ranging from 13% to ∼60%. Methods: Participants were 154 early-stage, non–small-cell lung cancer patients who had smoked within 3 months before surgery. Patients were followed for 12 months after surgery to assess smoking status and duration of continuous abstinence after surgery. Predictors included medical, smoking history, psychosocial, and demographic characteristics. Results: At some point after surgery, 42.9% of patients smoked; at 12 months after surgery, 36.9% were smoking. Sixty percent of patients who lapsed did so during the first 2 months after surgery. Smoking at follow-up was predicted by shorter quit duration before surgery, more intense Appetitive cravings (expectation of pleasure from smoking), lower income, and having a higher level of education. Time until the first smoking lapse was predicted by shorter quit duration before surgery, more intense Appetitive cravings to smoke, and lower income. Among those who lapsed, greater delay before the lapse was associated with abstinence at the 12-month follow-up assessment. Conclusions: Nearly half of non–small-cell lung cancer patients return to smoking after surgery if they have recent smoking histories. Most initial lapses happen within 2 months and occur in response to more recent smoking and more intense cravings. Findings suggest that interventions to prevent relapse should target those who wait until cancer surgery to quit smoking and should be started as soon as possible after treatment.

Increasing access to smoking cessation treatment in a low-income, HIV-positive population: the feasibility of using cellular telephones.

This study examined the feasibility of using cellular telephones to improve access to smoking cessation counseling in a low-income, HIV-positive population. Two pilot studies were conducted: (a). A survey of interest and barriers in participating in a smoking cessation intervention (n=49) and (b). a cellular telephone smoking cessation intervention in which participants were provided with free cellular telephones and received six telephone counseling sessions over a 2-week period (n=20). A primary care clinic serving a multiethnic, medically indigent, HIV-positive population served as the setting. Demographics and smoking status were assessed by self-report and expired-air carbon monoxide testing. In study 1, participants reported multiple barriers to participating in a smoking cessation intervention, including transportation, transience, and telephone availability. However, they also reported a high level of interest in participating in a smoking cessation intervention, with the greatest interest in a cellular telephone intervention. In study 2, 19 of the 20 participants successfully completed 2 weeks of smoking cessation counseling with a 93% (106 of 114 calls) contact rate. A total of 19 participants made a quit attempt, and the 2-week end of treatment point-prevalence abstinence rate was 75%. The provision of cellular telephones allowed for the implementation of a proactive telephone smoking cessation intervention providing an underserved population with access to care. Cellular telephones also may provide unique benefits because of the intensity of counseling and support provided as well as the ability to provide counseling in real-world, real-time situations (in vivo counseling).

Impact of a Cell Phone Intervention on Mediating Mechanisms of Smoking Cessation In Individuals Living with HIV/AIDS

Mounting evidence suggests that smokers living with HIV/AIDS have a significantly increased risk of numerous adverse health outcomes (both AIDS- and non-AIDS-related) compared with HIV-positive nonsmokers. Therefore, efforts to design and implement effective cessation programs for this ever-growing special population are warranted. The present study assessed the effects of a cell phone intervention (CPI) on hypothesized mediators (i.e., changes in depression, anxiety, social support, and self-efficacy) demonstrated to influence cessation outcomes in other populations. Ninety-five participants from an inner-city AIDS clinic were randomized to receive either the CPI or recommended standard of care (RSOC) smoking cessation treatment. Participants randomized to the RSOC group (n=47) received brief advice to quit, a 10-week supply of nicotine patches, and self-help materials. Participants randomized to the CPI group (n=48) received RSOC components plus a series of eight proactive counseling sessions delivered via cell phones. A series of regression analyses (linear and logistic) was used to assess the relationships between treatment group, the hypothesized mediators, and biochemically confirmed smoking cessation outcomes. Results indicated that the CPI group experienced greater reductions in anxiety and depression, and increases in self-efficacy compared with the RSOC group. Further, changes in depression, anxiety, and self-efficacy weakened the association between treatment group and cessation outcome. The mediator hypothesis, however, for social support was rejected, as the difference score was not significantly associated with treatment group. These results suggest that the efficacy of the CPI is at least partially mediated by its ability to decrease symptoms of distress while increasing self-efficacy.

Multidimensional analysis of body image concerns among newly diagnosed patients with oral cavity cancer

Body image is a critical psychosocial issue for patients facing treatment for oral cancer, yet there is limited research conducted in this area. This study uses a multidimensional approach to body image assessment and evaluates relationships between body image, demographic, health, and psychosocial variables.

Developing mobile phone text messages for tobacco risk communication among college students: a mixed methods study

BackgroundEngaging young adults for the purpose of communicating health risks associated with nicotine and tobacco use can be challenging since they comprise a population heavily targeted with appealing marketing by the evolving tobacco industry. The Food and Drug Administration seeks novel ways to effectively communicate risks to warn about using these products. This paper describes the first step in developing a text messaging program delivered by smartphones that manipulate three messaging characteristics (i.e., depth, framing, and appeal).MethodsPerceptions of community college students were described after previewing text messages designed to inform about risks of using conventional and new tobacco products. Thirty-one tobacco users and nonusers, aged 18–25 participated in five focus discussions held on two community college campuses. Attendees reviewed prototype messages and contributed feedback about text message structure and content. Qualitative data were coded and analyzed using NVivo Version 10.ResultsMost participants were female and two-thirds were ethnic minorities. A variety of conventional and new tobacco products in the past month were used by a third of participants. Three identified domains were derived from the qualitative data. These included perceived risks of using tobacco products, receptivity to message content, and logistical feedback regarding the future message campaign.ConclusionOverall, participants found the messages to be interesting and appropriate. A gap in awareness of the risks of using new tobacco products was revealed. Feedback on the prototype messages was incorporated into message revisions. These findings provided preliminary confirmation that the forthcoming messaging program will be appealing to young adults.

Assessing a conceptual framework of health-related quality of life in a HIV/AIDS population.

With the recognition of health-related quality of life (HRQOL) as an important outcome in the course of HIV-disease, it is important to gain a better understanding of the complex relationships among the various factors that influence it. This study assesses a conceptual framework of HRQOL, consisting of disease status, socio-economic status (SES), behavioral variables, symptom status, role-specific functional status and HRQOL, among a multiethnic, economically disadvantaged population of individuals living with HIV/AIDS. Self-report data were collected from 348 patients receiving care at a large HIV/AIDS care center, serving residents of a large metropolitan area. The relationships between the study variables were examined using structural equation modeling. Results indicated that the hypothesized framework provided a well-fitted solution to the data, χ2(44df)=57.62], p = 0.08 and root mean square error of approximation=0.03, 90% confidence interval 0.01; 0.05. This framework suggests that health-related variables fall along a continuum, beginning with disease status and ending in generic HRQOL. In addition, the framework suggests that behavioral factors (i.e., smoking status, alcohol consumption, and illicit drug use) and SES exert significant effects along this continuum and should be carefully considered when analyzing and interpreting HRQOL data.
