Greater engagement in valued activities is associated with less barriers to quitting smoking among smokers with mobility impairments

BACKGROUND

Individuals with mobility impairments (MI; use equipment to ambulate) have a high prevalence of both smoking and depression. Behavioral activation (BA) purports that depressed mood is remediated through valued activity engagement and may facilitate smoking cessation in MI populations.

OBJECTIVE

We examined cross-sectional associations between activity engagement and variables important for smoking cessation among a high-risk group of smokers (people with MIs) and also describe a smoking cessation intervention based on BA, given the lack of studies on smokers with MIs.

METHODS

This study used data from a smoking cessation trial enrolling smokers with MIs (n = 263). We assessed valued activities, activity type, activity restriction due to MI, and replacement of restricted activities. Motivation and confidence to quit smoking, number of cigarettes per day, and mood were also assessed. Analysis was performed with generalized linear (or logistic) regression models adjusted for age and physical functioning using aggregated data at baseline.

RESULTS

Greater number and frequency of valued activities was associated with less smoking, depression, negative affect, and stress and higher positive affect and self-efficacy to quit. Activity restriction was associated with greater odds of major depression, and activity replacement with lower odds of major depression, lower stress, and higher positive affect and self-efficacy. Strength of associations varied by activity type.

CONCLUSIONS

Consistent with our theoretical model, BA activity constructs were associated with several mediators of smoking outcomes in the expected directions. Smokers engaging in valued activities have more favorable profiles for smoking cessation and mood management.

Melanoma early detection with thorough skin self-examination: the "Check It Out" randomized trial

BACKGROUND

Monthly thorough skin self-examination (TSSE) is an important practice for early melanoma detection that is performed by a small minority of the population.

DESIGN

A randomized trial was conducted to determine whether a multicomponent intervention can increase TSSE performance and to describe the effects on performance of skin surgeries compared with a similar control intervention focused on diet.

SETTING/PARTICIPANTS

One thousand three hundred fifty-six patients attending a routine primary care visit in southeastern New England participated in this trial.

INTERVENTIONS

Participants received instructional materials, including cues and aids, a video, and a brief counseling session and (at 3 weeks) a brief follow-up phone call (from a health educator) and tailored feedback letters.

MEASURES

Performance of TSSE assessed by telephone interview and having a surgical procedure performed on the skin were confirmed by examining medical records.

RESULTS

TSSE was performed by substantially more participants at 2, 6, and 12 months in the intervention group than in the control group (55% vs 35%, p<0.0001 at 12 months). We also noted that a substantially higher proportion in the intervention group had skin surgery in the first 6 months (8.0% vs 3.6%, p=0.0005), but there was no difference at 6 to 12 months (3.9% vs 3.3%, p=0.5).

CONCLUSIONS

The TSSE intervention was effective in increasing performance of TSSE, in that it resulted in increased surgery on the skin, and that increase in skin procedures only persisted for 6 months. Intervention to increase TSSE may result in long-term benefit in early detection of melanoma while causing only a short-term excess of skin surgeries.

Reliability of assessment and circumstances of performance of thorough skin self-examination for the early detection of melanoma in the Check-It-Out Project

BACKGROUND

Thorough skin self-examination (TSSE) has substantial potential to reduce melanoma mortality by early detection.

METHODS

We interviewed 2,126 patients before a scheduled routine visit with a primary care physician, at which participation in a randomized trial was offered as part of the Check-It-Out Project. We asked about skin examination behavior and related issues.

RESULTS

By our a priori definition of TSSE, 18% of participants performed this activity, but other definitions led to widely varying estimates of 12% to 38%. Using a partner to assist in the examination was strongly associated with TSSE. That partner was generally the spouse, and wives were more likely to assist their husbands in these examinations than the reverse. The availability of a wall mirror was a particularly important predictor of TSSE performance. Visual impairment also affected performance.

CONCLUSIONS

Estimates of TSSE performance vary substantially with the questions used to elicit this information. Partners, particularly spouses, appear to play a critical role in the conduct of TSSE, and wives appear more often and more effectively engaged in this process. Appropriate circumstances, such as availability of a wall mirror, are also important factors. These findings can be used to design interventions to increase TSSE performance with the ultimate aim of reducing melanoma mortality.

Thorough skin examination for the early detection of melanoma

BACKGROUND

Melanoma is a major public health problem for which early detection may reduce mortality. Since melanoma is generally asymptomatic, this requires skin examination. We sought to evaluate the extent to which the general public has their skin examined by themselves, their partners, or health care providers and the frequency of these examinations.

METHODS

Random-digit-dial survey of adult Rhode Islanders.

RESULTS

Only 9% performed a thorough skin examination (TSE) at least once every few months, although over half of the sample reported conducting skin self-examination "deliberately and systematically." Participants were more likely to perform TSE if they were women and if their health care provider had asked them to examine their skin. Most participants reported that their health care provider never or rarely looked at the areas of their skin in which melanoma is most likely to arise.

CONCLUSIONS

The reported frequency of skin self-examination depends critically on the manner of inquiry. TSE by self or a partner is uncommon, and health care providers do not routinely examine the areas of the skin on which melanomas commonly arise.

Predicting physical activity change in men and women in two New England communities

We describe the predictors of change in physical activity in a population-derived sample of residents of two New England communities. In 1986-1987 and again in 1990-1991, we assessed the self-reported physical activity of 1,081 survey respondents using a single question concerning the frequency of exercise-induced sweating. We measured and analyzed sociodemographic variables, cardiovascular disease risk factors, health knowledge and beliefs, social support variables, and exercise performance variables at baseline as potential predictors of physical activity change. We defined physical activity change in subjects as follows: maintainers (12.2%) persisted with > or = 3 times per week of activity, adopters (16.0%) increased activity to > or = 3 times per week, quitters (11.9%) decreased activity to < 3 times per week, and sedentary (59.9%) individuals persisted with < 3 times per week of activity. Using polychotomous multiple logistic regression analysis, we found that short-term success with exercise and weight loss, school children's recommendation of exercise, and work outside the home predicted adoption or maintenance of increased physical activity in women. For men, short-term success with exercise and weight loss and health beliefs regarding the role of exercise in preventing heart attacks and stroke were the major determinants of maintaining or adopting increased physical activity. This identification of the predictors of physical activity change provides the rationale for future sex-specific strategies aimed at increasing regular physical activity and long-term adherence to an active lifestyle.
