Feasibility of a tobacco cessation intervention for pregnant Alaska Native women.

BACKGROUND: Among Alaska Native women residing in the Yukon-Kuskokwim (Y-K) Delta region of Western Alaska, about 79% smoke cigarettes or use smokeless tobacco during pregnancy. Treatment methods developed and evaluated among Alaska Native pregnant tobacco users do not exist. This pilot study used a randomized two-group design to assess the feasibility and acceptability of a targeted cessation intervention for Alaska Native pregnant women. METHODS: Recruitment occurred over an 8-month period. Enrolled participants were randomly assigned to the control group (n = 18; brief face-to-face counseling at the first visit and written materials) or to the intervention group (n = 17) consisting of face-to-face counseling at the first visit, four telephone calls, a video highlighting personal stories, and a cessation guide. Interview-based assessments were conducted at baseline and follow-up during pregnancy (>or=60 days postrandomization). Feasibility was determined by the recruitment and retention rates. RESULTS: The participation rate was very low with only 12% of eligible women (35/293) enrolled. Among enrolled participants, the study retention rates were high in both the intervention (71%) and control (94%) groups. The biochemically confirmed abstinence rates at follow-up were 0% and 6% for the intervention and control groups, respectively. DISCUSSION: The low enrollment rate suggests that the program was not feasible or acceptable. Alternative approaches are needed to improve the reach and efficacy of cessation interventions for Alaska Native women.

Feasibility of a telephone-based intervention for support persons to help smokers quit: a pilot study.

BACKGROUND: Nonsmokers have a potentially supportive role in tobacco cessation efforts. The present study examined the feasibility, acceptability, and potential efficacy of a telephone-based intervention for nonsmoking support persons. METHODS: A total of 59 support persons (mean age = 36 years, 92% female, 95% White) were randomly assigned to a control condition (N = 30; written materials only) or to a social cognitive theory-based intervention (N = 29; written materials and 5 weekly, 20- to 30-min telephone counseling sessions). Both support persons and smokers completed assessments separately by mail at baseline and at weeks 6 (end of treatment) and 26. RESULTS: Two thirds of the smokers reported low-moderate levels of motivation to quit at baseline as assessed by the contemplation ladder. Study retention rates were excellent, with 95% of both support persons and smokers completing the week 26 assessment. Moreover, 86% of support persons in the intervention group completed all five telephone sessions. Treatment acceptability was high for both support persons and smokers. Compared with the control condition, the intervention was associated with a significant increase in support person self-efficacy to help their smoker (p = .034) and outcome expectancies (p = .025) from baseline to week 6. However, the intervention was not associated with higher smoking abstinence rates or quit attempts. DISCUSSION: The program was successful in reaching smokers with lower levels of readiness to quit. The intervention was feasible and acceptable to both support persons and smokers. Although support persons and smokers can be engaged in this type of outreach program, refinements in the intervention approach are needed to improve the smoking outcomes.

Obesity: What is an elderly population growing into?

OBJECTIVES: Obesity is currently a major public health concern; however, there is little data available on the prevalence and impact of obesity within the elderly population. This review examines the prevalence and health effects of obesity among individuals aged > or =50. METHODS: PubMed (1996-2008) and PsychInfo (2002-2008) search engines were used to retrieve qualified peer-reviewed articles focusing on obesity or a health condition correlated with obesity using BMI or other weight index as a defining variable; and studies limited to the elderly (age 60+) or pre-elderly (50+). RESULTS: Worldwide, the elderly population is increasingly becoming obese regardless of socio-economic status. Among elderly persons, obesity increases the risks for a variety of morbidity conditions including cancers, diabetes, hypertension, stroke, heart disease, metabolic syndrome, obstructive sleep apnea syndrome, osteoarthritis, depression, disability, and lower scores on quality of life measures. In some reports, obesity has been linked to Alzheimer's disease and other forms of cognitive decline. Obesity significantly increases healthcare costs and nursing homes are currently ill equipped to address the needs of the rising number of obese residents. CONCLUSIONS: Obesity is increasing in the elderly population worldwide and is expected to continue to rise. Obesity is associated with disease and disability in addition to escalating healthcare costs, and hospitals and nursing homes are ill equipped to serve the obese elderly. It is imperative that research efforts and funding be devoted to studying the effects and the reduction of obesity in the elderly population.

Healthy women's motivators and barriers to participation in a breast cancer cohort study: a qualitative study.

PURPOSE: This focus group study describes motivators and barriers to participation in the Mayo Mammography Health Study (MMHS), a large-scale longitudinal study examining the causal association of breast density with breast cancer, involving completion of a survey, providing access to a residual blood sample for genetic analyses, and sharing their results from a screening mammogram. These women would then be followed up long term for breast cancer incidence and mortality. METHODS: Forty-eight women participated in six focus groups, four with MMHS non-respondents (n = 27), and two with MMHS respondents (n = 21). Major themes were summarized using content analysis. Social cognitive theory (SCT) was used as a framework for interpretation of the findings. RESULTS: Barriers to participation among MMHS non-respondents were 1) lack of confidence in their ability to fill out the survey accurately (self-efficacy); 2) lack of perceived personal connection to the study or value of participation (expectancies); and 3) fear related to some questions about perceived cancer risk and worry/concern (emotional coping responses). Among MMHS respondents, personal experience with cancer was reported as a primary motivator for participation (expectancies). CONCLUSIONS: Application of a theoretical model such as social cognitive therapy to the development of a study recruitment plan could be used to improve rates of study participation and provide a reproducible and evaluable strategy.
