How are we doing with physical activity?

An estimated 60% of U.S. adults are inactive or underactive, and nearly half of America's youth (aged 12 to 21 years) are not vigorously active on a regular basis. Downstream interventions provide individual strategies that effectively increase short-term participation in physical activity by 10% to 25%. Downstream and midstream approaches tailored to individual preferences have greater success. Packaging and disseminating physical activity programs for community, worksite, and health care settings are not as far along as for other areas, although inactivity prevalence is about twice that of smoking, and both risk factors have substantial morbidity and mortality. Less is known about effectiveness of upstream approaches, which have potential for the greatest public health impact. Suggestions include continued promotion of moderate-intensity physical activity, greater dissemination of successful programs, and investigation of physical environment influences.

Using the stages of change model to increase the adoption of physical activity among community participants.

PURPOSE: This study examined the use of the stages of change model to design an exercise intervention for community volunteers. DESIGN: The "Imagine Action" campaign was a community-wide event incorporating the involvement of local worksites and community agencies. Community members registering for the campaign were enrolled in a six-week intervention program designed to encourage participation in physical activity. SUBJECTS: Six hundred and ten adults aged 18 to 82 years old enrolled in the program. Seventy-seven percent of the participants were female and the average age was 41.8 years (SD = 13.8). SETTING: The campaign was conducted in a city with a population of approximately 72,000 and was promoted throughout community worksites, area schools, organizations, and local media channels. MEASURES: One question designed to assess current stage of exercise adoption was included on the campaign registration form as were questions about subject name, address, telephone number, birthdate, and gender. INTERVENTION: The intervention included written materials designed to encourage participants to initiate or increase physical activity, a resource manual describing activity options in the community, and weekly "fun walks" and "activity nights." RESULTS: A Stuart-Maxwell test for correlated proportions revealed that subjects were significantly more active after the six-week intervention. Sixty-two percent of participants in Contemplation became more active while 61% in Preparation became more active. CONCLUSIONS: Most participants increased their stage of exercise adoption during the six-week intervention. This study provides preliminary support for use of the stages of change model in designing exercise interventions.

Application of theoretical models to exercise behavior among employed women.

PURPOSE: This study examines the utility of three theoretical models--the stages of change model, self-efficacy theory, and the decisional balance model--in understanding exercise behavior among employed women. DESIGN: Data for this cross-sectional study were collected as part of a routine follow-up of a worksite-based smoking and health risk appraisal study. SETTING: The study was conducted in three Rhode Island worksites, including one manufacturing company, one medical center, and one retail outlet. SUBJECTS: Of a sample of 431 women who completed exercise questionnaires, 293 reported participation in a physical activity over the previous week. The average age of the sample was 41.1 years, and mean years of education was 12.8. MEASURES: Previously validated measures to determine stage of exercise behavior, exercise self-efficacy, exercise decisional balance, and physical activity participation were administered. Additional demographic information was also obtained. RESULTS: Frequency counts revealed that 39% of the population was sedentary, 34% were participating in irregular activity, and 27% were active. MANOVAs followed by one way ANOVAs revealed that women in Precontemplation scored the lowest and those in Maintenance scored the highest on the self-efficacy, pro, and decisional-balance indices, with the trend reversed on the con scale. A chi-square test revealed that women with one or more young children in the home were more likely to be in a lower stage of exercise adoption. CONCLUSIONS: Most of the women in this cross-sectional study did not engage in regular activity. Presence of young children in the home was significantly related to decreased activity.(ABSTRACT TRUNCATED AT 250 WORDS)

A multisite field test of the acceptability of physical activity counseling in primary care: project PACE.

Primary health-care providers have been encouraged to counsel their patients about regular physical activity, but there are significant barriers to effective counseling. In this study a program of training and materials was tested for acceptability to providers, office staff, and patients. Primary care providers and office staff were trained to use the Physician-based Assessment and Counseling for Exercise (PACE) materials in four geographical sites in the United States. The program was tested in a variety of settings and with diverse patient populations. The acceptability of the program during a five-month study period was evaluated through structured interviews. The training was effective in preparing the providers to counsel, and the program was generally acceptable to providers, office staff, and patients. Counseling was provided in less than five minutes by 70% of providers, and most patients reported following the recommendations given. The PACE program assists providers in overcoming barriers to counseling patients about physical activity. The PACE program is potentially an important part of a national effort to enhance the adoption and maintenance of physical activity among adults.

The impact of depression on smoking cessation in women.

INTRODUCTION: Cigarette smoking poses unique, but preventable health risks to women. Identification of barriers to womens' quitting is essential to tailor interventions accordingly. Major depression, whether historical, current, or subsyndromal, may present unique challenges to women quitting smoking. Although several reviews discuss women and smoking in general, this review focuses exclusively on the role of depression in womens' smoking. OBJECTIVES: The goals of this review are to (1) discuss and synthesize the current findings on the association between smoking and depression in women in general, and in particular subgroups of women (underserved, premenstrual, postpartum, menopausal), (2) discuss physician-assisted, pharmacologic, behavioral interventions for mood management, and (3) propose future avenues for intervention, research, and policy. IMPACT OF DEPRESSION: Major depression may influence smoking cessation in women because (1) depression is twice as common among women as men, (2) history of depression and negative affect have been associated with smoking treatment failure, (3) quitting smoking is especially difficult during certain phases of the reproductive cycle, phases that have also been associated with greater levels of dysphoria, and (4) subgroups of women who have a high risk of continuing to smoke (underserved, less educated, low SES) also have a high risk of developing depression. CONCLUSIONS: Since many women who are depressed (or who have developed depression during prior quit attempts) may be less likely to seek formal cessation treatment, practitioners have a unique opportunity to persuade their patients to quit. We discuss patient-treatment matching.

Promoting physical activity in women: the new challenges.

INTRODUCTION: Participation in physical activity has important implications for the physical and psychological well-being of women. Although researchers and educators have previously focused chiefly on the promotion of vigorous activity, exercise experts have focused recently on recommendations promoting moderate activity in American adults that may have important ramifications for women. OBJECTIVES: We discuss the prevalence of activity levels among women, the barriers women encounter in becoming active, and implications for the adoption and maintenance of moderate activity. INTERVENTIONS: We present the lessons learned from theory-based intervention studies, for these findings could serve as a basis to accomplish the new objectives. CONCLUSIONS: Finally, we outline the research and policy issues that should be addressed for researchers and health educators interested in preventive health care in women.
