Wheeling Walks: a community campaign using paid media to encourage walking among sedentary older adults.

BACKGROUND: Mass media may effect communitywide changes in health awareness, attitude, and behavior, but the approach remains unproven for physical activity. METHODS: Wheeling Walks promoted walking among sedentary 50- to 65-year-old adults in a West Virginia city of 31,420 people. This quasi-experimental communication intervention used theory of planned behavior and transtheoretical model constructs to change behavior by promoting 30 min of daily walking through paid media, public relations, and public health activities. Impact was determined by pre- and postintervention telephone surveys with 719 adults in the intervention community and 753 adults in the comparison community and observations of walkers at 10 community sites. RESULTS: Behavior observation showed a 23% increase in the number of walkers in the intervention community versus no change in the comparison community (OR = 1.31, 95% CI = 1.14-1.50). Thirty-two percent (32.2) of the baseline sedentary population in the intervention community reported meeting the CDC/ACSM/Surgeon General recommendation for moderate-intensity physical activity by walking at least 30 min at least five times per week versus 18.0% in the comparison community (OR = 2.12, 95% CI = 1.41-2.24). The intervention community also realized a pre to post increase in positive stage change (P < 0.001). CONCLUSIONS: This theory-based mass media campaign demonstrated increases in those meeting the recommended standard for moderate-intensity physical activity through walking and significant positive stage change.

The cognitive profile of those who intend to exercise but do not.

The purpose of this study was to identify the cognitive profile of people who intend to exercise but fail to carry out this intention. A theoretical framework was adopted to study the attitudinal beliefs of these persons about exercise, their evaluation of the associated consequences, and their normative beliefs and motivation to comply with these norms. Subjects were classified according to the congruence between stated intention and self-reported exercise behavior 2 months later in this way: positive intention and congruent behavior (CONG+, N = 74). positive intention and incongruent behavior (INCONG-, N = 45). negative intention and congruent behavior (CONG-, N = 42). negative intention and incongruent behavior (N = 2, not analyzed). MANOVA analysis indicated little difference between the cognitive profiles of inactive and active positive intenders. Relative to the CONG+ group, the INCONG- group perceived that regular exercise would be "tiring" (P less than 0.001) and "time consuming" (P less than 0.001); they also placed less value on the consequence of "being healthy" (P less than 0.05). Both groups differed from the CONG- group. As would be expected, those with positive intentions to exercise identified more advantages to being physically active. It appears that sedentary positive intenders perceived the exercise behavior as physically demanding and had difficulty in reconciling the time demands of an exercise program with their weekly schedules. This observation suggests that these two beliefs should be considered for the promotion of physical activity as well as the investigation of influential social and environmental variables.

Socioeconomic factors, health behaviors, and mortality: results from a nationally representative prospective study of US adults.

CONTEXT: A prominent hypothesis regarding social inequalities in mortality is that the elevated risk among the socioeconomically disadvantaged is largely due to the higher prevalence of health risk behaviors among those with lower levels of education and income. OBJECTIVE: To investigate the degree to which 4 behavioral risk factors (cigarette smoking, alcohol drinking, sedentary lifestyle, and relative body weight) explain the observed association between socioeconomic characteristics and all-cause mortality. DESIGN: Longitudinal survey study investigating the impact of education, income, and health behaviors on the risk of dying within the next 7.5 years. PARTICIPANTS: A nationally representative sample of 3617 adult women and men participating in the Americans' Changing Lives survey. MAIN OUTCOME MEASURE: All-cause mortality verified through the National Death Index and death certificate reviews. RESULTS: Educational differences in mortality were explained in full by the strong association between education and income. Controlling for age, sex, race, urbanicity, and education, the hazard rate ratio of mortality was 3.22 (95% confidence interval [CI], 2.01-5.16) for those in the lowest-income group and 2.34 (95% CI, 1.49-3.67) for those in the middle-income group. When health risk behaviors were considered, the risk of dying was still significantly elevated for the lowest-income group (hazard rate ratio, 2.77; 95% CI, 1.74-4.42) and the middle-income group (hazard rate ratio, 2.14; 95% CI, 1.38-3.25). CONCLUSION: Although reducing the prevalence of health risk behaviors in low-income populations is an important public health goal, socioeconomic differences in mortality are due to a wider array of factors and, therefore, would persist even with improved health behaviors among the disadvantaged.

Effects of minimal exercise and cognitive behavior modification on adherence, emotion change, self-image, and physical change in obese women.

The present investigation tested a 12-wk. treatment protocol which employed low intensity cardiovascular and resistance exercise as well as cognitive-behavior modification on 13 obese, previously sedentary women. Separate analyses were conducted on program maintenance, emotional change, and physiological change. Although self motivation was lower in the treatment group than in the control group (n=35), measures of exercise maintenance were significantly higher. Analyses within the treatment group only indicated significant improvements in measures of State Anxiety, Depression, Anger, Fatigue, Tension, and Vigor, also Health Evaluation, Body Area Satisfaction, and heightened Overweight Preoccupation, over the 12 weeks. Their feelings after individual bouts of exercise indicated significantly increased Positive Engagement, Revitalization, and Tranquility, and reduced Physical Exhaustion. Maximum volume of oxygen uptake (VO2max) significantly increased (2nd to 10th percentile), but not resting heart rate. No significant correlation was found between cardiorespiratory change and change in scores on depression and anxiety. No significant association was found between physiological change and change in body image. Preliminary evaluation of the minimal exercise treatment was given. The need to replicate findings with larger and different samples was emphasized.

Trace metal concentrations and susceptibility to oxidative stress in the polychaete Sabella spallanzanii (Gmelin) (Sabellidae): potential role of antioxidants in revealing stressful environmental conditions in the Mediterranean.

The polychaete Sabella spallanzanii (Gmelin) (Sabellidae) is a widely distributed species throughout the Mediterranean where it is commonly found in sheltered shallow areas and up to 30 m depth in more exposed waters. The sedentary habit, the filter-feeding behavior and its capability to colonize disturbed environments such as harbors, suggest the potential utility of this organism as a bioindicator in environmental monitoring programs. The aim of this work was a preliminary characterization of S. spallanzanii, integrating chemical data on trace metal concentrations with the biochemical analysis of antioxidant defenses which play an important role in mediating responses and adaptation to stressful environmental conditions. Organisms were collected in four locations of the Adriatic and Tyrrhenian Sea, characterized by a moderate impact or influenced by organic enrichment or sulphuric emissions. Trace metal concentrations (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) were comparable to those of other invertebrate species and quite typical for unpolluted environments. Analyses of individual antioxidants (superoxide dismutase, catalase, glutathione peroxidases, glutathione S-transferases, glutathione reductase) were integrated with measurement of the total oxyradical scavenging capacity toward specific forms of ROS; the TOSC assay, quantifying the overall capability of a tissue to neutralize specific reactive oxygen species provide a more integrated picture of the balance between prooxidant factors and antioxidant defenses, with important indications about the role of different ROS in appearance of oxidative disease. The antioxidant profile was influenced by the different physiological functions of the analyzed tissues, namely the branchial crown, involved in filtration of large volumes of seawater, and the thorax where digestive processes occur. The analysis of antioxidant defenses revealed significant variations in polychaetes from various sampling sites suggesting the influence of specific environmental conditions like those limiting oxygen availability. Our results confirm the role of antioxidants in adaptation to stressful environmental conditions and their importance in ecotoxicological studies for the sensitivity in revealing the occurrence of biological disturbance.

BMI, physical activity, and health care utilization/costs among Medicare retirees.

OBJECTIVE: To examine the influence of physical activity (PA) and BMI on health care utilization and costs among Medicare retirees. RESEARCH METHODS AND PROCEDURES: This cross-sectional study was based on 42,520 Medicare retirees in a U.S.-wide manufacturing corporation who participated in indemnity/preferred provider and one health risk appraisal during the years 2001 and 2002. Participants were assigned into one of the three weight groups: normal weight, overweight, and obese. PA behavior was classified into three levels: sedentary (0 time/wk), moderately active (1 to 3 times/wk), and very active (4+ times/wk). RESULTS: Generalized linear models revealed that the moderately active retirees had US 1456 dollars, US 1731 dollars, and US 1177 dollars lower total health care charges than their sedentary counterparts in the normal-weight, overweight, and obese groups, respectively (p < 0.01). The very active retirees had US 1823 dollars, US 581 dollars, and US 1379 dollars lower costs than the moderately active retirees. Health care utilization and specific costs showed similar trends with PA levels for all BMI groups. The total health care charges were lower with higher PA level for all age groups (p < 0.01). DISCUSSION: Regular PA has strong dose-response effects on both health care utilization and costs for overweight/obese as well as normal-weight people. Promoting active lifestyle in this Medicare population, especially overweight and obese groups, could potentially improve their well-being and save a substantial amount of health care expenditures. Because those Medicare retirees are hard to reach in general, more creative approaches should be launched to address their needs and interests as well as help reduce the usage of health care system.

Whittling away at obesity and overweight. Small lifestyle changes can have the biggest impact.

The epidemic of obesity in the United States has spread at such an alarming rate over the last decade that most adults are now overweight or obese. The association of obesity with mortality and a broad range of significant medical comorbidities portends staggering healthcare, social, and economic costs. Treatment should be directed at the fundamental imbalance between energy intake and expenditure in the context of an environment that increasingly favors excess weight. Therefore, treatment plans need to address the multiple factors that contribute to obesity, including high-calorie diets, sedentary lifestyles, and weight-sustaining behaviors. Primary care physicians would do well to focus on helping willing patients make small changes motivated more by health promotion and fitness than by weight loss.

Health behavior changes after a cancer diagnosis: what do we know and where do we go from here?

Survival rates for certain types of cancer have improved over the past few decades. Changing unhealthy behaviors such as smoking, poor diet, and sedentary life-style among individuals who have been diagnosed with cancer may help to reduce cancer treatment sequelae, possibly reduce risk of recurrence for specific types of cancer, and reduce risk for other common diseases such as cardiovascular disease, obesity, and hypertension. This article reports the prevalence of each of these behaviors among those diagnosed with cancer and reviews interventions that have targeted these risk behaviors. There is considerable variation in the type of research questions asked, the methodologic quality of the research, sample sizes, and the outcomes observed across studies focusing on changing the three health risk behaviors. In the final section, we provide guidelines for researchers in developing health behavior interventions for individuals diagnosed with cancer and highlight challenges that should be addressed.

Challenges for the older academic in balancing work and wellness.

OBJECTIVE: The objective of this study was to describe the risks for the development of MSDs in older academics. METHOD: Four older academics needed modification of their offices to reduce symptoms of MSDs. In order to improve their occupational performance, data were gathered through interviews and observations, facilitating selection of interventions responsive to their unique client factors, physical contexts, and the organizational environment. RESULTS: Older academics did not perceive risks for the development of MSDs in work that was sedentary. Their routines included few health and wellness behaviors in a culture rewarding excessive work, facilitating commitment to the organization, and understating the importance of health and wellness to the academic community. CONCLUSIONS: Occupational therapists must reframe sedentary work as physically demanding and potentially risky for the development of MSDs, and must recognize the organizational influences on the work of academics. Prolonging work life might likely result from modifications in the physical context and from the academic adopting healthy lifestyle routines within multiple environments.

Environmental and endocrine correlates of tactic switching by nonterritorial male tree lizards (Urosaurus ornatus).

Animals often exhibit individual variation in their behavioral responses to the same stimuli in the biotic or abiotic environment. To elucidate the endocrine mechanisms mediating such behavioral variation, we have been studying a species of lizard with two distinct male phenotypes. Here we document behavioral variation across years in one of the two male phenotypes of the tree lizard, Urosaurus ornatus, and present hormone data that support an endocrine mechanism underlying this behavioral variation. Nonterritorial male tree lizards appear to be nomadic rovers in some years and sedentary satellites in others, whereas territorial males are always territorial. This behavioral variation by nonterritorial males was correlated with environmental conditions. In environmentally harsher years (as assessed by rainfall), nonterritorial males appear to behave as nomads, whereas in more benign years they are more site-faithful. A between-year comparison of levels of corticosterone and testosterone for the two male phenotypes supports a model for how hormones underlie the males' reproductive tactics, particularly the nonterritorial males' behavioral plasticity. In an environmentally harsher (drier) year, both types of males had higher corticosterone levels than in a milder (wetter) year, but only nonterritorial males had lower testosterone in the relatively harsher year. We propose that disruptive selection for individual variation in hormonal responses to environmental cues may be a common mechanism underlying the evolution of alternative male reproductive tactics in this and other species.

Physical activity behavior change: issues in adoption and maintenance.

The many benefits of participation in regular moderate- or vigorous-intensity physical activity are well established, yet more than 60% of the population is sedentary or insufficiently active. Published studies have revealed that behavior modification and cognitive-behavior modification can be successfully used to assist patients, healthy adults, and youth in the adoption of physically active lifestyles. However, few studies with adults and youth have examined the maintenance of physical activity behavior beyond 6 months of adoption of this behavior. Maintenance of physical activity is critically important because ongoing participation in the behavior is necessary to sustain health benefits. Knowledge of effective intervention strategies for long-term maintenance of physical activity is at an early stage. The authors provide a summary of what is known about the maintenance of physical activity behavior in adults and youth and how physical activity behavior relates to other health behaviors such as smoking, as well as recommendations for research on physical activity behavior change and maintenance.

The effects of aerobic exercise on psychological adjustment: a randomized study of sedentary obese women attempting weight loss.

This study evaluated the psychological effects of aerobic conditioning in 40 moderately obese, sedentary women participating in a 12-week behavioral weight loss program. Participants were randomly assigned to a no-exercise or moderate walking condition. Emotional impact of the treatment was assessed in two ways: (1) Subjects reported subjective mood prior to each eating episode and (2) the SCL-90-R was administered before and after the program. Exercisers lost more weight and body fat than non-exercisers. Both groups of subjects showed numerous improvements in mood as a result of participating in the weight loss program. Exercise had no specific differential effect on emotions as measured by daily mood ratings or the SCL-90-R. Exercise did not appear to add appreciably to the psychological benefits of losing weight in this sedentary obese population. Future studies utilizing longer periods of aerobic exercise training, larger sample size, and exercise specific measures are recommended.

Hormone replacement therapy and hip fracture risk: effect modification by tobacco smoking, alcohol intake, physical activity, and body mass index.

The authors prospectively studied the overall effect of hormone replacement therapy (HRT) on hip fracture risk and the effect modification by behavioral habits and body mass index. A total of 6,159 postmenopausal women from the Copenhagen Center for Prospective Population Studies, Copenhagen, Denmark, with initial examination in 1976-1978 were followed until 1993. During follow-up 363 hip fractures were identified. Women who reported current use of HRT had a lower risk of hip fracture as compared with women who were nonusers (relative risk (RR) = 0.71; 95 percent confidence interval (CI): 0.50, 1.01). Use of HRT was associated with a lower risk of hip fracture in former (RR = 0.55; 95 percent CI: 0.22, 1.37) and current (RR = 0.61; 95 percent CI: 0.38, 0.99) smokers but not in never smokers (RR = 1.10; 95 percent CI: 0.60, 2.03). HRT was also associated with lower risk of hip fracture among alcohol drinkers (RR = 0.36; 95 percent CI: 0.14, 0.90) and among sedentary women (RR = 0.42; 95 percent CI: 0.18, 0.98) but not among nondrinkers (RR = 0.99; 95 percent CI: 0.61, 1.61) and physically active women (RR = 0.92; 95 percent CI: 0.42, 2.04). There was no evidence of interaction between use of HRT and body mass index. In conclusion, the protective effect of HRT on hip fracture appears to be strongest in women who ever smoked, in women who drink alcohol, and in women who are sedentary. The results suggest that history of behavioral habits offers important information concerning the probable degree of protection against hip fracture afforded by HRT.

[Helping patients with risky health behaviors: some suggestions for motivational interviewing].

Helping patients modify risky health behaviors, including cigarette smoking, at-risk alcohol use, sedentary lifestyle and unhealthy diet, is a common and sometimes frustrating task. Motivational interviewing was developed from the notion that simple advice usually does not lead to behavioral change and may be even misperceived by patients. Based on active listening and an empathic attitude, some principles of motivational interviewing may be easily adapted to a primary care consultation. These principles facilitate positive, relaxed and constructive atmosphere for behavior change discussions and have been associated with promising results. This article presents key concepts of motivational interviewing such as ambivalence, resistance and stages of change, illustrated with practical examples.

Behavioral risk factors among members of a health maintenance organization.

BACKGROUND: Co-occurrence of risk behaviors (RBs) substantially increases the risk of disease. This study examines the co-occurrence of four health risk behaviors (i.e., smoking, high-fat diet, sedentariness, and high-risk drinking) and demographic and psychosocial variables associated with number of RBs in a sample of members of a health maintenance organization who participated in the Seasonal Variation in Cholesterol (Seasons) study. METHODS: Seasons study baseline data were used. Subjects completed a self-administered questionnaire packet containing questions on demographics, smoking history, and leisure-time physical activity, a 7-day dietary recall instrument, and various psychosocial measures. Results presented here are based on 496 subjects with complete data on all RBs. RESULTS: Forty-three percent of participants had > or = two RBs. The most prevalent RB combination was high-fat diet/sedentariness, with 30% of subjects reporting both RBs. Associations between RBs were observed. A greater number of RBs were observed among younger and less-educated subjects, those with higher depression scores, and subjects who perceived their health as poor. CONCLUSIONS: Findings highlight the importance of designing and evaluating primary care-based screening programs and interventions for multiple RBs.

Health-compromising behaviors among Vietnamese adolescents: the role of education and extracurricular activities.

PURPOSE: To examine the prevalence of unhealthy behaviors among a cohort of Vietnamese adolescents in California; to examine the relationship between these behaviors and school-related variables (school performance, educational risk behaviors, higher-education aspirations, and participation in extracurricular activities); and to assess the differences that may exist between males and females with regard to these factors. METHODS: We conducted telephone interviews with 783 Vietnamese adolescents, aged 12-17 years, recruited through telephone listings from four California counties where large Vietnamese populations reside: San Francisco, Santa Clara, Los Angeles, and Orange. Of the 783 completed interviews, 60.8% were conducted in English and 39.2% in Vietnamese. The main outcome measure is a health risk behavior scale that includes adolescents' reports of ever smoking a cigarette, sedentary vs. active lifestyle, consumption of fruits and vegetables, consumption of foods high in fat, ever drinking alcohol, and ever engaging in sexual behavior. Multiple regression analyses were employed to estimate the association among the demographic variables, acculturation, school performance, aspirations, extracurricular activities, and the overall health risk. RESULTS: Females were significantly more sedentary than males. Over one-quarter (29%) of the females reported not having participated in vigorous physical activity on 3 or more days per week, compared with just 18% of the males. Most adolescents reported they had never tried cigarettes (84%), never used alcohol (77%), and never had sex (97%). Males were more likely than females to report a higher frequency of experimentation with smoking and drinking. Overall, school performance and participation in extracurricular activities were significantly related to the health risk behavior scale. Adolescents who demonstrated at least one educational risk (ever skipped school or ever sent out of the classroom) were more likely to engage in other risky behaviors. Also, older and more acculturated adolescents were at increased risk of engaging in health-compromising behaviors. Analysis by gender revealed that the variables age, educational risk, and chance of attending college were all related to health risk behavior for both males and females. Among the boys, those who reported achieving an average grade of B or better had a decreased risk of engaging in health-compromising behaviors; however, neither extracurricular activities nor acculturation was related to health-compromising behaviors in boys. Among the girls, the reverse was true: lack of participation in extracurricular activities was related to health-compromising behaviors, whereas grades were not a significant risk factor. CONCLUSIONS: Among sampled Vietnamese adolescents in California, health risk behaviors are common and inversely related to some school performance indicators. Using these indicators to identify high-risk groups could allow targeted educational programs or interventions for the mitigation of health-compromising behaviors.

Physical activity behavior of American Indian mothers.

BACKGROUND: Mothers of young children who live in low-income households are a population at-risk for sedentary living that could experience important health benefits from improved physical activity behavior. Previous research among Caucasian mothers attending the Women, Infants and Children (WIC) program showed that the Transtheoretical Model of behavior change was an appropriate model for designing interventions for activity promotion. PURPOSE: This study examined the Transtheoretical Model of behavior change in relationship to the physical activity behavior of low-income American Indian mothers. DESIGN: A descriptive-correlational study employed a purposive sample (N = 30) of six American Indian mothers at each of five stages of behavior change. Participants were recruited from a Women, Infants and Children program located on the Pine Ridge Indian Reservation in South Dakota. Instruments included the 7-day Activity Recall, Stages of Exercise Adoption tool, Pros and Cons to Exercise tool, Self-efficacy for Exercise scale, and the Processes of Exercise Adoption tool. FINDINGS: Significant relationships were found between stage of change and energy expenditure indices (r = 0.69-0.74, p < .01), pros (r = 0.62, p < .01), cons (r = -0.58, p < .05), decisional balance (r = 0.59, p < .01), and self-efficacy (r = 0.60, p < .01). Pros and cons were different from a prior study of mothers attending the Women, Infants and Children program. CONCLUSIONS: The Transtheoretical Model is relevant to American Indian mothers and should be tested in future physical activity interventions.

Older women and exercise: theory of planned behavior beliefs.

Despite well-documented benefits of exercise, aging women remain largely sedentary. Further understanding of beliefs associated with exercise could result in more-effective public health interventions to increase exercise in this vulnerable population. This study examined the relationships between theory of planned behavior constructs and exercise behavior and exercise intention in older women. Constructs from the theory of planned behavior (behavioral beliefs, perceived control beliefs, and normative beliefs) were examined in a sample of 225 women aged 65 and older. Exercise was measured with the Baecke Physical Activity Scale. All women were interviewed, to prevent literacy and vision problems from hampering participation. Significant predictors of exercise behavior were perceived control beliefs and behavioral beliefs. Significant predictors of exercise intentions were perceived control beliefs, behavioral beliefs, and normative beliefs. Specific belief items predicting exercise behavior were that exercise is good for health and that exercise is difficult because of tiredness, as well as the lack of commitment and time. These findings provide partial support for the application of the theory of planned behavior to exercise in older women. The findings suggest that interventions should focus on increasing women's confidence that they can overcome barriers to exercise.
