Smith NC. Black-White disparities in women's physical health: The role of socioeconomic status and racism-related stressors. SOCIAL SCIENCE RESEARCH 2021; 99:102593.

Abstract
Black women have elevated rates of multiple physical illnesses and conditions when compared to White women - disparities that are only partially explained by socioeconomic status (SES). Consequently, scholars have called for renewed attention to the significance of racism-related stress in explaining Black-White disparities in women's physical health. Drawing on the biopsychosocial model of racism as a stressor and the intersectionality perspective, this study examines the extent to which SES and racism-related stressors - i.e., discrimination, criminalization, and adverse neighborhood conditions - account for disparities in self-rated physical health and chronic health conditions between Black and White women. Results indicate that Black women have lower SES and report greater exposure to racism-related stressors across all domains. Moreover, I find that SES and racism-related stressors jointly account for more than 90% of the Black-White disparity in women's self-rated physical health and almost 50% of the Black-White disparity in chronic health conditions. Theoretical and policy implications of these findings are discussed.

[PMID: 32543426 DOI: 10.1016/j.healthplace.2020.102337] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Revised: 03/31/2020] [Accepted: 04/02/2020] [Indexed: 12/19/2022]
Abstract
Socioeconomically disadvantaged groups are less likely to be physically active. Walking is important to public health, therefore understanding correlates of walking will inform the development of targeted interventions. The aim of this systematic review was to examine the correlates of walking among socioeconomically disadvantaged adults. PubMed/MEDLINE and Scopus were searched up to February 2020 and titles/abstracts and full-texts were screened against eligibility criteria. Methodological quality was assessed. Correlates were synthesized when two or more comparisons were available. 35 studies were selected for synthesis. 21 examined overall walking, 16 examined leisure-time walking and 9 examined walking for transport (8 examined two or more types of walking). Employment status, home ownership, self-rated health, density or number of social ties, perceived neighborhood aesthetics, perceived walkability and perceived individual safety were positively associated with overall walking. Social support for physical activity from friends and family and perceived individual safety were positively associated with leisure-time walking. Objective walkability, perceived walkability and perceived individual safety were positively associated with walking for transport. Most studies were cross-sectional, did not report response rates and used a validated measure of physical activity. Strategies to improve self-rated health, social ties, neighborhood aesthetics, walkability and perceptions of individual safety should be the focus of interventions that aim to improve walking among socioeconomically disadvantaged groups. Recommendations for future studies include the need to focus on leisure-time walking and walking for transport; the correlates of walking in males; prospective longitudinal designs; psychological, cognitive and emotional variables; and social, behavioral attributes and skills.

Abstract
BACKGROUND AND OBJECTIVES Participation in leisure physical activity (PA) and engagement in PA interventions among older adults is influenced by socioeconomic status (SES), race/ethnicity, and environment. However, studies of PA for medically underserved older adults have not yet been systematically evaluated. The objective of this study is to map the nature and extent of research conducted on PA participation, interventions, and components of effective leisure PA programs for medically underserved older adults. RESEARCH DESIGN AND METHODS The five-stage approach was used to conduct this scoping review. We searched PubMed, CINAHL, and Cochrane Library for peer-reviewed studies published between 2006 and 2016. Data extracted from selected studies included study population, study type, purpose of intent, evidence level, barriers to PA participation, and components of PA intervention. RESULTS Three hundred and ninety-two articles were identified, and 60 studies were included in the final data charting. Existing literature showed that most studies remained descriptive in nature, and few intervention studies have achieved a high level of evidence. Among 21 intervention studies, only 4 were explicitly conducted for older adults. Culturally adapted materials, race/ethnicity-specific barriers and facilitators, and form of intervention were important components for intervention programs. DISCUSSION AND IMPLICATIONS Findings indicate that more studies are needed to reduce health disparities related to PA participation for medically underserved older adults. Intervention components such as race/ethnicity-relevant barriers and facilitators and culturally sensitive materials are also needed for PA interventions targeting underserved older adults in order to provide evidence for best practices.

Abstract
Rural-dwelling, overweight/obese, limited-resource individuals and women have the lowest leisure-time physical activity rates among Americans. This community-based, single-group pre- posttest study sought to increase physical activity, step counts, and promote weight loss in 104 low-income women (84% rural). Analyses included nonparametric and repeated-measures analyses of variance to determine physical activity behaviors, step counts, and weight loss. Results show, from pre- to postintervention, participants improved self-reported step counts, physical activity goal setting and behaviors, and body weight. This study adds support that text message programs can reach a high-risk, limited-resource, predominantly rural population to promote physical activity and weight loss.

Wearable activity monitors to assess performance status and predict clinical outcomes in advanced cancer patients. NPJ Digit Med 2018; 1:27. [PMID: 31304309 PMCID: PMC6550281 DOI: 10.1038/s41746-018-0032-6] [Citation(s) in RCA: 90] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 04/06/2018] [Accepted: 04/10/2018] [Indexed: 11/12/2022] Open
Abstract
An objective evaluation of patient performance status (PS) is difficult because patients spend the majority of their time outside of the clinic, self-report to providers, and undergo dynamic changes throughout their treatment experience. Real-time, objective activity data may allow for a more accurate assessment of PS and physical function, while reducing the subjectivity and bias associated with current assessments. Consenting patients with advanced cancer wore a wearble activity monitor for three consecutive visits in a prospective, single-cohort clinical trial. Provider-assessed PS (ECOG/Karnofsky) and NIH PROMIS® patient-reported outcomes (PROs) were assessed at each visit. Associations between wearable activity monitor metrics (steps, distance, stairs) and PS, clinical outcomes (adverse events, hospitalizations, survival), and PROs were assessed using correlation statistics and in multivariable logistic regression models. Thirty-seven patients were evaluated (54% male, median 62 years). Patients averaged 3700 steps, 1.7 miles, and 3 flights of stairs per day. Highest correlations were observed between average daily steps and ECOG-PS and KPS (r = 0.63 and r = 0.69, respectively p < 0.01). Each 1000 steps/day increase was associated with reduced odds for adverse events (OR: 0.34, 95% CI 0.13, 0.94), hospitalizations (OR: 0.21 95% CI 0.56, 0.79), and hazard for death (HR: 0.48 95% CI 0.28–0.83). Significant correlations were also observed between activity metrics and PROs. Our trial demonstrates the feasibility of using wearable activity monitors to assess PS in advanced cancer patients and suggests their potential use to predict clinical and patient-reported outcomes. These findings should be validated in larger, randomized trials. Wearable activity monitors provide an objective and continuous measure of general wellbeing and physical function among patients with advanced cancer. Gillian Gresham from Cedars-Sinai Medical Center in Los Angeles, California, USA, and colleagues enlisted 37 patients with metastatic or inoperable cancer to wear wristbands that wireless measure heart rate and activity patterns over the span of 2 weeks. At weekly clinic visits, the patients also filled in health questionnaires and their healthcare providers made independent evaluations. The researchers found a reasonably high correlation between the clinician-assessed performance status and the average daily step total calculated by the wristband. More steps also translated into lower odds of serious complications, hospitalizations or death. The study shows the feasibility of using wearable technology to track the ability of patients with advanced cancer to perform certain activities of daily living.

Abstract
OBJECTIVE To evaluate changes in dietary and physical activity behaviors and weight after implementation of a 12-week text messaging initiative (My Quest). DESIGN The researchers conducted a 1-group, pre- to posttest study design to determine changes after implementation of a text messaging initiative developed using the tenets of the Social Cognitive Theory. SETTING A total of 55 Alabama counties (84% rural) with high rates of poverty, overweight/obesity, and chronic diseases. PARTICIPANTS Convenience sample of low-income, primarily overweight/obese women (n = 104). INTERVENTION Short texts (n = 2-3/d) provided health tips, reminders, and goal-setting prompts. Weekly electronic newsletters provided tips and recipes. Participant self-monitored body weight weekly. MAIN OUTCOME MEASURE Outcomes included goal setting, self-efficacy, behavioral and environmental factors, self-monitoring, and body weight; data collection occurred through text message response and online surveys. ANALYSIS Analyses were conducted using McNemar test (dichotomous data), Wilcoxon signed rank test (ordinal data), or paired t test (continuous data). RESULTS Participants significantly (P < .05) improved dietary and physical activity behaviors and food environment; increased dietary and physical activity goal setting; and reduced body weight. CONCLUSIONS AND IMPLICATIONS A low-cost, text messaging initiative particularly targeting women residing in rural communities with high rates of poverty and obesity can promote weight loss and improve dietary and physical activity behaviors. Future studies may include a control group and social support component such as group text messaging.

Abstract
Using a sample of middle class blacks and whites living in urban and suburban areas, this article focuses on how perceptions of the racial composition of neighborhoods influence leisure-time physical activity. Using an ordinal representation of an underlying continuous indication of the perceived percentage of blacks and whites within an egocentric neighborhood, the results show that black men are significantly less likely to be physically active in neighborhoods perceived as predominately white. Alternatively, they are more likely to be physically active in neighborhoods perceived as racially diverse and predominately black. Conversely, for black women, white women, and white men, physical activity increases as the perception of one's neighborhood becomes increasingly white. Black women are significantly less likely to engage in physical activity in neighborhoods perceived as predominately black and urban. Drawing upon the intersectionality framework, I discuss how perceptions of criminalization and safety lead to different levels of leisure-time physical activity for middle class black women and men relative to their white middle class counterparts.

Abstract
Purpose: To examine the effects of a community-based behavioral intervention with multiple components on health outcomes among low-income and uninsured adults who were obese and had diabetes and treated in a “real-world” setting. Design: A longitudinal design with a retrospective comparison group was used to examine the ability of a health promotion program to improve body mass index (BMI) and hemoglobin A1c (HbA1c) among 87 treatment group and 62 comparison group participants. Setting: Urban/metropolitan city in the United States. Intervention: A community-based behavioral intervention with 3 components including health-coach visits, registered dietitian visits, and exercise consultations delivered over 12 months. Measures: Biometric measurements were collected at baseline, 3, 6, 9, 12, and 18 months, whereas self-reported measurements were collected at baseline, 6 months, and 12 months. Analysis: Linear mixed models with participant-level random intercepts were fitted for BMI and HbA1c. Results: The treatment group demonstrated reductions in BMI (percentage change = −2.1%, P < .001) and HbA1c (−0.6%, P < .001) as well as improvement in diabetes knowledge (+5.4%, P = .025), whereas the comparison group did not show any improvements in biometric measures. Dietitian visits were the most effective treatment component to reduce HbA1c (coefficient = −0.08, P = .025). Conclusion: Multiple component behavioral intervention in community settings, particularly when delivered by registered dietitians, shows promise to combat the dual epidemic of obesity and diabetes among low-income and uninsured patients.

Abstract
This study examined the effects of a 12-month walking intervention in overweight/obese, low socioeconomic women. Forty-six women (48.2 ± 8.0 years) entered the study. Outcomes included weight, waist and hip circumferences, body mass index (BMI), blood pressure, glycosylated hemoglobin, blood lipids, fibrinogen, and high-sensitivity C-reactive protein (hsCRP). Both intention-to-treat analyses in all participants and group analyses in study completers only (3K group = increased steps/day by ≥3,000; No Δ group = did not increase steps/day by ≥3,000) were conducted. Group × time ANOVA was used. In study completers, 3K significantly increased steps/day (6,903 ± 3,328 to 12,323 ± 5,736) compared to No Δ (4,926 ± 3,374 to 5,174 ± 3,095) from baseline to 12 months. There was a significant time effect for weight (P = 0.030), BMI (P = 0.029), and hsCRP (P = 0.044). Low socioeconomic women who adhere to a long-term, pedometer-based walking intervention significantly increased steps/day and may improve body weight, BMI, and hsCRP. This could help reduce health disparities in this population over time.

Abstract
Obesity is the cause of up to one-third of all cancers affecting women today, most notably endometrial, colon and breast cancer. Women's health providers are poised to advise women on obesity's link to cancer development, but often lack resources or training to provide appropriate counseling. Here, we review obesity's role in increasing the risk of several common reproductive system conditions faced by women, including polycystic ovarian syndrome, infertility, gynecologic surgical complications, and pregnancy complications. These events can be used as teachable moments to help frame the discussion of weight management and promote cancer prevention. We also review national guidelines and existing tangible weight-loss strategies that can be employed within the outpatient women's health setting to help women achieve weight loss goals and affect cancer prevention.

Abstract
[Purpose] To test the hypothesis that toe grasping strength is associated with daily physical activity in older adults. [Subjects] Fifty-seven Japanese women, aged 52-78 years, volunteered. [Methods] Toe grasping and knee extension strength were measured. Physical activity was also measured, using an accelerometer, and the total duration of each level of exercise intensity (light, moderate, and vigorous) and average step counts were calculated. Subjects were separated into two groups on the basis of accelerometer-determined step counts: LOW (n=28, <8000 steps/day) and HIGH (n=29, ≥8000 steps/day). [Results] Body mass index and body composition (% fat and fat-free mass) were similar between the two groups. Absolute and relative toe grasping strengths (divided by body weight) were greater in HIGH than in LOW. However, both absolute and relative knee extension strength were similar between the groups. Relative toe grasping and knee extension strength correlated with all 3 intensities of physical activity and average step count. After adjusting for age, the duration of light plus moderate physical activity and average step counts correlated to toe grasping strength but not to knee extension strength. [Conclusion] Our results suggest that toe grasping strength may be associated with the amount of light intensity daily physical activity.

Abstract
UNLABELLED Revascularization aims at improving walking ability in patients with arterial claudication. The highest measured distance between 2 stops (highest-MDCW), the average walking speed (average-WSCW), and the average stop duration (average-DSCW) can be measured by global positioning system, but their evolution after revascularization is unknown.We included 251 peripheral artery diseased patients with self-reported limiting claudication. The patients performed a 1-hour stroll, recorded by a global positioning system receiver. Patients (n = 172) with confirmed limitation (highest-MDCW <2000m) at inclusion were reevaluated after 6 months. Patients revascularized during the follow-up period were compared with reference patients (ie, with unchanged lifestyle medical or surgical status). Other patients (lost to follow-up or treatment change) were excluded (n = 89).We studied 44 revascularized and 39 reference patients. Changes in highest-MDCW (+442 vs. +13 m) and average-WSCW (+0.3 vs. -0.2 km h) were greater in revascularized than in reference patients (both P < 0.01). In contrast, no significant difference in average-DSCW changes was found between the groups. Among the revascularized patients, 13 (29.5%) had a change in average-WSCW, but not in highest-MDCW, greater than the mean + 1 standard deviation of the change observed for reference patients.Revascularization may improve highest-MDCW and/or average-WSCW. This first report of changes in community walking ability in revascularized patients suggests that, beyond measuring walking distances, average-WSCW measurement is essential to monitor these changes. Applicability to other surgical populations remains to be evaluated. REGISTRATION http://www.clinicaltrials.gov/ct2/show/NCT01141361.

Abstract
Obesity has been characterized as a disease. Strategies to change the incidence and prevalence of this disease include a focus on changing physical and social environments, over and above individual-level strategies, using a multilevel or systems approach. We focus our attention on evidence published between 2008 and 2013 on the effectiveness of interventions in nutrition environments, i.e., environmental interventions designed to influence the intake of healthful foods and amount of energy consumed. An overarching socioecological framework that has guided much of this research was used to characterize different types of environmental strategies. Intervention examples in each area of the framework are provided with a discussion of key findings and related conceptual and methodological issues. The emphasis in this review is on adults, but clearly this literature is only one part of the picture. Much research has been focused on child-specific interventions, including environmental interventions. Some evidence suggests effectiveness of policy-based or other types of interventions that aim to regulate or restructure environments to promote healthy dietary choices, and these strategies would apply to both children and adults. Opportunities to evaluate these policy changes in adults' social and physical environments are rare. Much of the existing research has been with children. As conceptual and methodological issues continue to be identified and resolved, we hope that future research in this domain will identify environmental strategies that can be included in intervention toolboxes to build healthy nutrition environments for both adults and children.

Abstract
BACKGROUND To determine the effectiveness of two goal setting pedometer based walking program for people with type 2 diabetes, one employing supervised exercise group with pedometer and the other employing self reported group with pedometer. METHODS A total of 102 type 2 diabetic outpatients (28 women, 74 men) between the age of 40-70 years were recruited and randomly allocated into 3 groups: supervised exercise group with pedometer (Group A), self reported exercise group with pedometer (Group B) and a control group (Group C) for 16 weeks. Subjects were asked to respond to the Audit of Diabetes Dependent Quality of Life (ADDQoL) and well being questionnaire at two occasions i.e. 0 week and after 16 weeks of intervention. Paired t test were used within the groups to compare Mean ± SD for all the parameters at baseline and at the end of 16 weeks. Differences between the groups were compared using analysis of variance (ANOVA). Statistical difference was further analyzed by Post hoc analysis using Bonferroni method. RESULTS The item "Freedom to eat" had the highest negative impact among all the subgroups. Other domains that were adversely affected by diabetes are 'leisure activity', 'do physically', 'physical appearance', 'self confidence', 'future' and 'financial situation'. In the group A significant reduction were noted among all the items except long distance journey (p<0.05). In the group B participants experienced reduction among all the domains except long distance journey, sex life and living condition. CONCLUSION Pedometer determined activity has the potential to improve the quality of life. Supervised Walking using a pedometer was found more effective in improving quality of life and general wellbeing for Asian Indians with type 2 diabetes.

Abstract
PURPOSE To examine behavioral patterns and sociodemographic predictors of diet, inactivity, and tobacco use among a diverse sample of residents from low-income housing developments. DESIGN In this cross-sectional survey study, households and residents were randomly selected using multistage cluster sampling. Setting . The study was conducted in 20 low-income housing developments in the Boston, Massachusetts, metropolitan area. SUBJECTS Subjects were 828 residents who completed the survey (response rate = 49.3%). Forty-one percent of participants were Hispanic and 38% were non-Hispanic Black. Measures . Outcomes measured were diet, inactivity, and tobacco use. Predictors measured were age, race/ethnicity, gender, education, country in which the subject was born, language spoken, and financial hardship. Analysis . Logistic regression analyses were conducted to examine the association of three health behaviors with sociodemographic factors. RESULTS Age, gender, language spoken, and financial hardship showed significant relationships with all three behaviors. For example, those who reported less financial hardship (odds ratio [OR] = 1.75) were more likely to eat healthier. Residents who spoke no English, or at least one language in addition to English, were significantly more likely to report healthier eating (OR = 2.78 and 3.30, respectively) than those who spoke English only. Men were significantly more likely to report less healthy eating (OR = 0.65) than were women. Similar trends emerged for inactivity and tobacco use. CONCLUSION Effective health promotion interventions in low-income housing developments that leverage protective factors while addressing risk factors have the potential to reduce income-related health disparities in these concentrated resource-deprived neighborhoods.

Abstract
Step counting (using pedometers or accelerometers) is widely accepted by researchers, practitioners, and the general public. Given the mounting evidence of the link between low steps/day and time spent in sedentary behaviours, how few steps/day some populations actually perform, and the growing interest in the potentially deleterious effects of excessive sedentary behaviours on health, an emerging question is "How many steps/day are too few?" This review examines the utility, appropriateness, and limitations of using a reoccurring candidate for a step-defined sedentary lifestyle index: <5000 steps/day. Adults taking <5000 steps/day are more likely to have a lower household income and be female, older, of African-American vs. European-American heritage, a current vs. never smoker, and (or) living with chronic disease and (or) disability. Little is known about how contextual factors (e.g., built environment) foster such low levels of step-defined physical activity. Unfavorable indicators of body composition and cardiometabolic risk have been consistently associated with taking <5000 steps/day. The acute transition (3-14 days) of healthy active young people from higher (>10 000) to lower (<5000 or as low as 1500) daily step counts induces reduced insulin sensitivity and glycemic control, increased adiposity, and other negative changes in health parameters. Although few alternative values have been considered, the continued use of <5000 steps/day as a step-defined sedentary lifestyle index for adults is appropriate for researchers and practitioners and for communicating with the general public. There is little evidence to advocate any specific value indicative of a step-defined sedentary lifestyle index in children and adolescents.

Abstract
BACKGROUND Physical activity decreases risk of colon polyps and colon cancer and might reduce risk of colon cancer recurrence. Focusing on recent calls for translation of epidemiologic evidence into clinical care, our pilot study delivered an evidence-based physical activity intervention in adults with polyps, who are thus at elevated risk of developing colon cancer. The objective was to evaluate change in physical activity, measured by steps per day and minutes of moderate/vigorous physical activity. METHODS Sixteen adults with adenomas detected and removed at screening colonoscopy were recruited to a 12-week physical activity intervention. Participants were randomized to receive a standard (30 minutes/day) or high (60 minutes/day) walking program. Physical activity was measured via blinded pedometer and accelerometer at baseline and follow-up. Intervention messages focused on self-monitoring using pedometers and overcoming barriers to engaging in physical activity. RESULTS Participants in both arms significantly increased objectively measured minutes of moderate/vigorous physical activity over the course of the intervention. Both arms exceeded the intervention goal, but there was not a significant difference between arms at follow-up. Results were similar for pedometer measured physical activity, with a significant overall increase in steps/day from baseline to follow-up, but no between arm difference in change. CONCLUSION Simple interventions of minimal contact time focusing on walking can significantly increase physical activity in individuals at increased risk of developing colon cancer.

Abstract
PURPOSE Descriptive physical activity epidemiology of the U.S. population is critical for program development and resource allocation. The purpose of this project was to describe step-defined categories (as measured by accelerometer) of U.S. adults and to determine predictors of sedentary classification (<5000 steps/d). DESIGN The National Health and Nutrition Examination Survey (NHANES) is an annual, nationally representative survey used to determine the health status of the U.S. populace. SETTING In-home interviews and physical examination components of NHANES. PARTICIPANTS Overall, 4372 eligible adults wore accelerometers in the 2005-2006 NHANES; 628 were excluded, which yielded 3744 adults (of which 46.8% were men). MEASURES Steps per day; body mass index (BMI); demographic, household and behavioral variables. ANALYSIS Means and frequencies were calculated. Logistic regression was utilized to determine predictors of sedentary classification. RESULTS Overall, 36.1% were sedentary (i.e., <5000 steps/d); 47.6% were low to somewhat active (5000-9999 steps/d); 16.3% were active to highly active (≥10,000 steps/d). Advancing age (odds ratio [OR], 1.95; confidence intervals [CIs], 1.78, 2.13), higher BMI (OR, 1.40; CIs, 1.23, 1.59), female sex (OR, 1.86; CIs, 1.46, 2.36), African-American versus European-American ethnicity (OR, 1.36; CIs, 1.13, 1.65), household income versus ≥$45,000 (<$25,000: OR, 1.94; CIs, 1.40, 2.69; $25,000-$44,000: OR, 1.51; CIs, 1.23, 1.85), and current versus never smoker (OR, 1.53; CIs, 1.26, 1.86) variables had higher odds of sedentary classification. Usual daily occupational/domestic physical activity categories of standing/walking (OR, .51; CIs, .38, .69); lifting/climbing (OR, .26; CIs, .17, .38); and heavy loads/labor (OR, .16; CIs, .10, .26) had lower odds of sedentary classification than sitting. CONCLUSIONS Over one-third of the U.S. population was classified as sedentary by accelerometer-determined steps per day, and several characteristics predicted sedentary classification.

Abstract
This study aimed to measure ambulation in infantry army basic training, and to evaluate if covering more distance can explain stress fractures in a stressor-stress model. Forty-four male combat recruits (18.7 ± 0.7 years) participated in a 6-month rigorous high intensity combat training program. Baseline data included anthropometric measurements, VO(2)max, and psychological questionnaires. Actual distance covered was measured using a pedometer over an 11-week training period. Psychological questionnaires were repeated after 2 months. Sixteen recruits were diagnosed with stress fractures by imaging (SFi = 36.4%). Statistical analysis included comparing measured variables between SFi and those without stress fractures (NSF). The recruits covered 796 ± 157 km, twofold the distance planned of 378 km (P < 0.001). The SFi group covered a distance 16.4% greater than that of the NSF group (866 ± 136 and 744 ± 161 km, respectively, P < 0.01), and also demonstrated greater psychological stress. These data reveal the importance of adherence to or enforcement of military training programs. In the light of these data, the Israeli Defense Forces program needs reappraisal. A stressor-stress response might explain the susceptibility of certain recruits for injury. Using advanced technology, monitoring ambulation may prevent stress fracture development by limiting subjects exceeding a certain level. Psychological profile may also play a role in predicting stress fracture development.

Abstract
Physical activity guidelines from around the world are typically expressed in terms of frequency, duration, and intensity parameters. Objective monitoring using pedometers and accelerometers offers a new opportunity to measure and communicate physical activity in terms of steps/day. Various step-based versions or translations of physical activity guidelines are emerging, reflecting public interest in such guidance. However, there appears to be a wide discrepancy in the exact values that are being communicated. It makes sense that step-based recommendations should be harmonious with existing evidence-based public health guidelines that recognize that "some physical activity is better than none" while maintaining a focus on time spent in moderate-to-vigorous physical activity (MVPA). Thus, the purpose of this review was to update our existing knowledge of "How many steps/day are enough?", and to inform step-based recommendations consistent with current physical activity guidelines. Normative data indicate that healthy adults typically take between 4,000 and 18,000 steps/day, and that 10,000 steps/day is reasonable for this population, although there are notable "low active populations." Interventions demonstrate incremental increases on the order of 2,000-2,500 steps/day. The results of seven different controlled studies demonstrate that there is a strong relationship between cadence and intensity. Further, despite some inter-individual variation, 100 steps/minute represents a reasonable floor value indicative of moderate intensity walking. Multiplying this cadence by 30 minutes (i.e., typical of a daily recommendation) produces a minimum of 3,000 steps that is best used as a heuristic (i.e., guiding) value, but these steps must be taken over and above habitual activity levels to be a true expression of free-living steps/day that also includes recommendations for minimal amounts of time in MVPA. Computed steps/day translations of time in MVPA that also include estimates of habitual activity levels equate to 7,100 to 11,000 steps/day. A direct estimate of minimal amounts of MVPA accumulated in the course of objectively monitored free-living behaviour is 7,000-8,000 steps/day. A scale that spans a wide range of incremental increases in steps/day and is congruent with public health recognition that "some physical activity is better than none," yet still incorporates step-based translations of recommended amounts of time in MVPA may be useful in research and practice. The full range of users (researchers to practitioners to the general public) of objective monitoring instruments that provide step-based outputs require good reference data and evidence-based recommendations to be able to design effective health messages congruent with public health physical activity guidelines, guide behaviour change, and ultimately measure, track, and interpret steps/day.

Abstract
African American (AA) and low SES populations report poor health behaviors and outcomes. This study aimed to increase understanding of barriers to participating in healthful behaviors and programs in AA residents of public housing. Twenty two apparently healthy, AA residents (50% female, M = 43.9 years) completed in depth interviews, which were taped, transcribed and analyzed using a constant comparison approach. Residents demonstrated some awareness of health recommendations, but described limited adherence. Physical activity for recreation was reported as primarily for youth, with adults engaging in limited physical activity (primarily incidental to other activities). Barriers reported by residents were both personal and environmental. Few residents were aware of local neighborhood opportunities for physical activity or healthful eating. Future efforts should focus on increasing understanding of health promoting behaviors and awareness and efficacy of residents to connect with the resources of their surrounding communities.

Abstract
OBJECTIVES We sought to examine the association between structural, functional, and normative social factors and physical activity among urban, low-income, racially/ethnically diverse adults. METHODS We conducted a baseline cross-sectional survey among residents of 12 low-income housing communities in metropolitan Boston, Massachusetts. Participants were also asked to wear a pedometer for 5 days. We analyzed complete data from 1112 residents (weighted n = 1635). RESULTS Residents with smaller social networks were significantly less physically active than were residents with larger social networks (b = -1503.7; P = .01) and residents with conflicting demands were more active than were residents with none (b = 601.6; P = .01), when we controlled for employment status, gender, poverty level, current health status, age, and perceived safety. Social networks were most strongly associated with physical activity among Hispanics and younger residents (aged 18-35 years). CONCLUSIONS These findings indicate that social factors, including social networks and role-related conflicting demands, may be important drivers of physical activity among low-income populations. Researchers and practitioners should consider social factors in developing multilevel physical activity interventions for this population.

Abstract
This study examined the associations between walking behavior and the perceived environment and personal factors among older adults. Sixty participants age 65 yr or older (mean 77 +/- 7.27, range 65-92) wore pedometers for 3 consecutive days. Perceived environment was assessed using the Neighborhood Environment Walkability Scale (abbreviated version). Physical function was measured using the timed chair-stands test. The mean number of steps per day was 5,289 steps (SD = 4,029). Regression analyses showed a significant association between personal factors, including physical function (relative rate = 1.05, p < .01) and income (RR = 1.43, p < .05) and the average daily number of steps taken. In terms of perceived environment, only access to services was significantly related to walking at the univariate level, an association that remained marginally significant when controlling for personal characteristics. These results suggest that among this sample of older adults, walking behavior was more related to personal and intrinsic physical capabilities than to the perceived environment.

Abstract
The article examines the importance of managing weight to reduce risk for developing cancer and for survival among cancer patients and presents a set of strategies that can be useful to guide clinical advice to patients for whom weight control is an important adjunct to risk management or to improve quality of life and disease-free survival after diagnosis. Weight, weight gain, and obesity account for approximately 20% of all cancer cases. Evidence on the relation of each to cancer is summarized, including esophageal, thyroid, colon, renal, liver, melanoma, multiple myeloma, rectum, gallbladder, leukemia, lymphoma, and prostate in men; and postmenopausal breast and endometrium in women. Different mechanisms drive etiologic pathways for these cancers. Weight loss, particularly among postmenopausal women, reduces risk for breast cancer. Among cancer patients, data are less robust, but we note a long history of poor outcomes after breast cancer among obese women. While evidence on obesity and outcomes for other cancers is mixed, growing evidence points to benefits of physical activity for breast and colon cancers. Dosing of chemotherapy and radiation therapy among obese patients is discussed and the impact on therapy-related toxicity is noted. Guidelines for counseling patients for weight loss and increased physical activity are presented and supported by strong evidence that increased physical activity leads to improved quality of life among cancer survivors. The “Five A's” model guides clinicians through a counseling session: assess, advise, agree, assist, arrange. The burden of obesity on society continues to increase and warrants closer attention by clinicians for both cancer prevention and improved outcomes after diagnosis.

Abstract
OBJECTIVES We implemented and evaluated multiple interventions to increase walking activity at a multicultural public housing site. METHODS A community-based participatory research partnership and community action teams assessed assets and barriers related to walking and developed multiple interventions to promote walking activity. Interventions included sponsoring walking groups, improving walking routes, providing information about walking options, and advocating for pedestrian safety. A pre-post study design was used to assess the changes in walking activity. RESULTS Self-reported walking activity increased among walking group participants from 65 to 109 minutes per day (P = .001). The proportion that reported being at least moderately active for at least 150 minutes per week increased from 62% to 81% (P = .018). CONCLUSIONS A multicomponent intervention developed through participatory research methods that emphasized walking groups and included additional strategies to change the built and social environments increased walking activity at a public housing site in Seattle.

Abstract
BACKGROUND Although discrimination has been identified as a potential determinant of existing racial/ethnic health disparities, no studies have investigated whether racial discrimination contributes to disparities in physical activity. PURPOSE The primary aim of the current study was to examine the association between interpersonal racial discrimination and physical activity. METHODS Baseline data were collected during 2004-2005 among a predominately black and Hispanic sample of adult residents living in 12 low-income-housing sites in Boston MA (n=1055). Residents reported experiences of lifetime racial discrimination during interviewer-administered surveys and wore a pedometer for 5 days to measure physical activity. For analyses, performed in 2009, linear regression models with a cluster design were conducted to predict physical activity, measured as steps per day. RESULTS Nearly 48% of participants reported ever experiencing racial discrimination, and discrimination was most commonly experienced on the street or in a public setting. No association was found between discrimination and physical activity, when examined in bivariate, multivariable, or race-stratified models. CONCLUSIONS The current results indicate that self-reported racial discrimination is not a key determinant of physical activity among residents living in low-income housing. However, additional research is warranted to address current limitations of this study.

Abstract
BACKGROUND A limited body of evidence, mostly based on self-report, is available regarding physical activity levels among American-Indian adults. PURPOSE This study aims to examine physical activity levels objectively using pedometers among a large cohort of American-Indian adult participants in the Strong Heart Family Study (SHFS). METHODS Physical activity levels in 2604 American-Indian adults, aged 18-91 years, from 13 American-Indian communities were assessed using Accusplit AE120 pedometers over a period of 7 days during 2001-2003. Anthropometric measurements were also assessed. All data analyses were conducted in 2008. Age-adjusted Pearson correlations were used to examine the relationship between average steps per day and age and anthropometric variables. Subjects were placed in age and BMI categories (according to National Heart, Lung, and Blood Institute cut points) to examine trends in physical activity with increasing age and BMI. RESULTS Daily pedometer steps ranged from 1001 to 38,755. Mean step counts by age group for men were 5384 (aged 18-29 years); 5120 (aged 30-39 years); 5040 (aged 40-49 years); 4561(aged 50-59 years); 4321 (aged 60-69 years); and 3768 (aged >or=70 years) and for women, 5038 (aged 18-29 years); 5112 (aged 30-39 years); 5054 (aged 40-49 years); 4582 (aged 50-59 years); 3653 (aged 60-69 years); and 3770 (aged >or=70 years). A significant linear trend in physical activity was noted with increasing age (p=0.002 for men, p<0.0001 for women) and with increasing BMI (p=0.05 for men, p=0.04 for women). CONCLUSIONS Objectively measured data suggest that inactivity is a problem among American-Indian adults and that a majority of American-Indian adults in the SHFS may not be meeting the minimum physical activity public health recommendations. Efforts to increase physical activity levels in this population are warranted.

Abstract
BACKGROUND This paper presents the study design, intervention components, and baseline data from Open Doors to Health, a study designed to address social contextual factors in colorectal cancer (CRC) prevention for low-income, racial/ethnic minority populations. METHODS A cluster randomized design with 12 housing sites as the primary sampling units was used: 6 sites were assigned to a "Peer-led plus Screening Access" (PL) condition, and 6 were assigned to "Screening Access only" (SCR) condition. Study-related outcomes were CRC screening, physical activity (measured as mean steps/day), and multivitamin use. RESULTS At baseline (unweighted sample size = 1554), two-thirds self-reported that they were current with screening recommendations for CRC (corrected for medical records validation, prevalence was 52%), with half having received a colonoscopy (54%); 96% had health insurance. Mean steps per day was 5648 (se mean = 224), and on average 28% of the sample reported regular multivitamin use. Residents reported high levels of social support [mean = 4.40 (se = .03)] and moderately extensive social networks [mean = 2.66 (se = .02)]. CONCLUSION Few studies have conducted community-based studies in public housing communities; these data suggest areas for improvement and future opportunities for intervention development and dissemination. Findings from the randomized trial will determine the effectiveness of the intervention on our health-related outcomes as well as inform future avenues of research.

Abstract
In older adults, as in younger individuals, habitual moderate-intensity physical activity is associated with a reduced risk of various chronic health conditions, including certain types of cardiovascular and musculoskeletal disease and certain forms of cancer. However, the pattern of physical activity associated with such benefits remains unclear. One problem is that most investigators have examined patterns of physical activity using either subjective questionnaires or accelerometer or pedometer measurements limited to a single week, despite clear evidence of both the unreliability/invalidity of questionnaires and seasonal changes in activity patterns. Since 2000, we have thus conducted an interdisciplinary study examining the habitual physical activity and health of elderly people living in a medium-sized Japanese town (the Nakanojo Study). In about one-tenth of some 5000 available subjects aged > or =65 years, physical activity has already been assessed continuously for 24 h/day for >8 years using a specially adapted pedometer/accelerometer. This device has a storage capacity of 36 days and can distinguish >10 intensities of physical activity (expressed in metabolic equivalents [METs]). Data have to date been summarized as daily step counts and daily durations of activity of <3 and >3 METs, averaged over a 1-year period. This article provides a detailed overview of both factors influencing habitual physical activity and relationships between such activity and health in an elderly population. To date, analyses have been cross-sectional in type. Substantial associations have been noted between the overall health of participants and both the daily duration of effort undertaken at an intensity of >3 METs and the daily step count. In men, the extent of health is associated more closely with the daily duration of activity of >3 METs than with the daily step count, whereas in women, the association is closer for the step count than for the duration of activity >3 METs. In both sexes, the threshold amount of physical activity associated with better health is greater for physical than for mental benefits: >8000 versus >4000 steps/day and/or >20 versus >5 min/day at an intensity >3 METs, respectively. In other words, better physical health is seen in those spending at least 20 min/day in moderate walking (at a pace of around 1.4 m/s [5 km/h]) and a further >60 min of light activity per day. In contrast, better mental health is associated with much smaller amounts of deliberate physical activity. The daily step count and the daily durations of activity of <3 and >3 METs are all influenced by meteorological factors, particularly precipitation and mean ambient temperature. Activity decreases exponentially to about 4000 steps/day as precipitation increases. Excluding the influence of rainfall, the daily step count peaks at a mean outdoor temperature of around 17 degrees C; above and especially below such readings, physical activity decreases as a quadratic function of temperature. Seasonal changes in microclimate should thus be considered when designing interventions intended to increase the habitual physical activity of elderly people. The observed associations between physical activity and health outcomes point to a need for longitudinal analyses; these should examine potential causal interpretations of the current findings and elucidate possible additional mediating variables.

Abstract
BACKGROUND Accelerometers were incorporated in the 2003-2004 National Health and Nutritional Examination Survey (NHANES) study cycle for objective assessment of physical activity. This is the first time that objective physical activity data are available on a nationally representative sample of U.S. residents. The use of accelerometers allows researchers to measure total physical activity, including light intensity and unstructured activities, which may be a better predictor of health outcomes than structured activity alone. The aim of this study was to examine objectively determined physical activity levels by sex, age and racial/ethnic groups in a national sample of U.S. adults. METHODS Data were obtained from the 2003-2004 NHANES, a cross-sectional study of a complex, multistage probability sample of the U.S. population. Physical activity was assessed with the Actigraph AM-7164 accelerometer for seven days following an examination. 2,688 U.S. adults with valid accelerometer data (i.e. at least four days with at least 10 hours of wear-time) were included in the analysis. Mean daily total physical activity counts, as well as counts accumulated in minutes of light, and moderate-vigorous intensity physical activity are presented by sex across age and racial/ethnic groups. Generalized linear modeling using the log link function was performed to compare physical activity in sex and racial/ethnic groups adjusting for age. RESULTS Physical activity decreases with age for both men and women across all racial/ethnic groups with men being more active than women, with the exception of Hispanic women. Hispanic women are more active at middle age (40-59 years) compared to younger or older age and not significantly less active than men in middle or older age groups (i.e. age 40-59 or age 60 and older). Hispanic men accumulate more total and light intensity physical activity counts than their white and black counterparts for all age groups. CONCLUSION Physical activity levels measured objectively by accelerometer demonstrated that Hispanic men are, in general, more active than their white and black counterparts. This appears to be in contrast to self-reported physical activity previously reported in the literature and identifies the need to use objective measures in situations where the contribution of light intensity and/or unstructured physical activity cannot be assumed homogenous across the populations of interest.

Abstract
PURPOSE To investigate the presence of reactivity, if any, to wearing sealed and unsealed pedometers, with and without step count recording. METHODS On the first visit to the laboratory, 63 participants (41 females and 22 males; age = 23.6 +/- 9.6 yr, body mass index = 22.7 +/- 3.0 kg x m(-2)), blinded to the study aim, were provided with a sealed pedometer (New Lifestyles NL-1000) and informed that it was a "body posture monitor" (covert monitoring). Participants wore the pedometer throughout waking hours for 1 wk. On return to the laboratory, stored step counts were downloaded, and participants were informed that the device was a pedometer. Participants wore the pedometer under three more conditions-sealed, unsealed, and unsealed plus logging daily steps in an activity diary-each having a duration of 1 wk. The order of participation in each condition (sealed/unsealed/diary) was balanced across participants. Mean daily step counts recorded during the four conditions were compared using a repeated-measures ANOVA. RESULTS There was a significant overall effect of condition (P < 0.001; covert monitoring = 8362 +/- 2600 steps per day; sealed condition = 8832 +/- 2845 steps per day; unsealed condition = 9176 +/- 3299 steps per day; diary condition = 9635 +/- 2709 steps per day), with post hoc analyses revealing that mean step counts were significantly higher in the diary condition than those reported during both the covert and sealed conditions (both P < 0.003). No significant gender effects were observed (P = 0.33). CONCLUSION The greatest increase in step counts occurred in the diary condition, suggesting that reactivity to pedometers is greatest when participants are requested to wear an unsealed pedometer and record their step counts. This has validity implications for short-term pedometer studies investigating habitual free-living activity that require participants to provide a daily log of their step counts.

Abstract
There has been growing interest in the protective health benefits of multivitamin use (MVU). Relatively little research has investigated the factors associated with MVU among adults across a broad age range, particularly among lower-income, racially/ethnically diverse adults. In light of standing MVU recommendations and documented health benefits for certain groups, as well as ongoing studies evaluating the potential health benefits of multivitamins, vitamin D, and calcium, research among this understudied population is warranted. The aims of this paper were to assess the association between MVU and (1) sociodemographic, (2) preventive/health, and (3) patient/provider factors among a racially and ethnically diverse adult sample of over 1,500 low-income housing residents living in Boston, Massachusetts (USA). Bivariate and multivariable logistic regression models were the primary analytic strategy for investigating these associations. In multivariable analyses, sociodemographic factors (female gender, older age, and White or Other race/ethnicity) were significantly associated with regular MVU (p < or = .05). Preventive/health variables (health status, physical activity, and body mass index) and characteristics of patient/provider relationships (having a regular provider, last provider visit, decision-autonomy, and quality of relationship) were not significantly associated with MVU. While more evidence is needed to understand the benefits of MVU, future studies should address low use of MVU among lower-income, multi-ethnic populations, particularly in light of health disparities.

Abstract
OBJECTIVE The use of wearable motion-sensing technology offers important advantages over conventional methods for obtaining measures of physical activity and/or physical functioning in aged individuals. This review aims to identify the actual state of applying wearable systems for monitoring mobility-related activity in older populations. In this review we focus on technologies and applications, research designs, feasibility and adherence aspects, and clinical relevance of wearable motion-sensing technology. DATA SOURCES PubMed (MEDLINE since 1990), Ovid (BIOSIS, CINAHL), and Cochrane (Central) and reference lists of all relevant articles were searched. REVIEW METHODS Two authors independently reviewed randomized and non-randomized trials on people above 65 years systematically. Quality of selected articles was scored and study results were summarised and discussed. RESULTS Two hundred and twenty-seven abstracts were considered. After application of inclusion criteria and full text reading, 42 articles were taken into account in a full text review. Twenty of these papers evaluated walking with step counters, other papers used varying accelerometry approaches for obtaining overall activity measures (n = 16), or for monitoring changes in body postures and activity patterns (n = 17). Seven studies explicitly mentioned feasibility and/or adherence aspects. Eight studies presented outcome evaluations of interventions. Eight articles were representing descriptive research designs, three articles were using mixed descriptive and exploratory research designs, 23 articles used exploratory research-type designs, and eight articles used experimental research designs. CONCLUSION Although feasible methods for monitoring human mobility are available, evidence-based clinical applications of these methods in older populations are in need of further development.

Abstract
This study examined objectively determined walking profiles of older adults across a wide range of sociocultural backgrounds. All individuals (N = 415; 131 men age 70.5 +/- 9.2 yr and 284 women age 71.5 +/- 9.0 yr) underwent physiological measurements, completed pen-and-paper surveys, and wore a pedometer for 7 consecutive days. The total sample accumulated a mean of 3,987 +/-2,680 steps/day. Age (r = -.485, p < .001) and body-mass index (BMI; r = -.353, p < .001) were negatively associated with steps per day. Multivariate analysis revealed that race/ethnic category (F = 3.15, df = 3), gender (F = 2.46, df = 1), BMI (F = 6.23, df = 2), income (F = 9.86, df = 1), education (F = 43.3, df = 1), and retirement status (F = 52.3, df = 1) were significantly associated with steps per day. Collectively these categories accounted for 56% of the variance in walking activity in this independently living, community-dwelling older adult sample. Sedentary characteristics highlighted within, and step-per-day values specific to, older adults have implications for planning targeted physical activity interventions related to walking activity in this population.

Abstract
BACKGROUND Bariatric surgery candidates' physical activity (PA) level might contribute to the variability of weight loss and body composition changes following bariatric surgery. However, there is little research describing the PA of patients undergoing bariatric surgery to inform PA recommendations in preparation for, and following, surgery. We describe the PA assessment in the Longitudinal Assessment of Bariatric Surgery-2 study at 6 sites in the United States and report preoperative PA level. We also examined the relationships between objectively determined PA level and the patient's body mass index and self-reported purposeful exercise. METHODS The participants wore an accelerometer and completed a PA diary. Standardized measures of height and weight were obtained. RESULTS Of the 757 participants, 20% were sedentary (<5000 steps/d), 34% had low activity (5000-7499 steps/d), 27% were somewhat active (7500-9999 steps/d), 14% were active (10,000-12,499 steps/d), and 6% were highly active (>or=12,500 steps/d). Body mass index was inversely related to the mean number of steps daily and the mean number of steps each minute during the most active 30 minutes of each day. The most commonly reported activities were walking (44%), gardening (11%), playing with children (10%), and stretching (7%). The self-reported minutes of exercise accounted for 2% of the variance in the objectively determined steps. CONCLUSION Patients present for bariatric surgery with a wide range of PA levels, with almost one half categorized as somewhat active or active. Body mass index was inversely related to the total amount and intensity of PA. Few patients reported a regular preoperative exercise regimen, suggesting most PA is accumulated from activities of daily living. Patients' report of daily minutes of walking or exercise might not be a reliable indication of their PA level.

Abstract
OBJECTIVE Several studies have reported low levels of physical activity among immigrant women. However, few studies have attempted to explore possible causes underlying this phenomenon. This study intended to explore immigrant women's attitudes and experiences of physical activity and exercise. The ultimate goal was to find methods that can increase levels of physical activity among immigrant women. METHODS A qualitative exploratory study was undertaken in Stockholm County, Sweden, involving 63 immigrant women from Chile, Iraq, and Turkey. Data were collected through interviews in 10 focus groups. The analysis was based on grounded theory approaches. Constant comparative analysis and theoretical sampling were employed to construct categories. MAIN FINDINGS The model that emerged illustrated the core process, that is, enabling exercise. The model also described the women's attitudes and experiences and their ideas of how exercise can be made possible. The women agreed that the local community should recognize the problem and arrange exercise in familiar places. In addition, they called for activities that felt appropriate. If appropriate exercise was arranged, the women sometimes decided to participate. Otherwise, they hesitated or waited. CONCLUSION If appropriate activities are arranged, levels of physical activity and exercise might increase among immigrant women. Future studies could explore specific activities that can facilitate immigrant women's opportunities to exercise.

Abstract
OBJECTIVE Physical inactivity is common among older populations and American Indians. Our objective was to compare two methods for increasing physical activity and walking among American Indian elders. METHODS We conducted a two arm randomized trial to increase physical activity in 125 American Indians aged 50-74 years at the Seattle Indian Health Board in 2005. Participants were randomized into either an activity monitoring (N=63) or activity monitoring with a pedometer (N=62) arm over a six-week period. Outcomes included self-reported physical activity and well-being, and the 6-min walk test. RESULTS There were no group differences in self-reported physical activities and well-being. The 6-min walk test yielded no between-group differences. All participants increased the frequency of leisure walking (p<0.01), frequency of all exercise-related activities (p<0.01), frequency of moderate-intensity exercise activities (p<0.01), and improved weekly caloric expenditure for all exercise activities (p<0.05) by the end of the trial. CONCLUSIONS Pedometers did not confer enhanced performance on the physical activity outcomes beyond those achieved through self-monitoring. Physical activity can be promoted among at-risk groups in a brief, inexpensive manner in primary care. Exercise prescription and culturally relevant enhancement strategies may optimize physical activity outcomes for elder American Indians.

Abstract
We compare walking and obesity rates in two African-American neighborhoods that are similar in urban form but different in level of neighborhood disadvantage. We find higher rates of utilitarian walking in the neighborhood with higher density and disadvantage and more destinations within walking distance. However levels of leisure walking and physical activity were not higher, and rates of obesity were not lower in the non-poor neighborhood with better maintenance, more sidewalks and recreational facilities. Different types of barriers to physical activity reported in the two neighborhoods and the high rates of overweight and obesity in both may explain the findings.

Abstract
BACKGROUND Despite its health benefits, physical inactivity is pervasive, particularly among those living in lower-income urban communities. In such settings, neighborhood safety may impact willingness to be regularly physically active. We examined the association of perceived neighborhood safety with pedometer-determined physical activity and physical activity self-efficacy. METHODS AND FINDINGS Participants were 1,180 predominantly racial/ethnic minority adults recruited from 12 urban low-income housing complexes in metropolitan Boston. Participants completed a 5-d pedometer data-collection protocol and self-reported their perceptions of neighborhood safety and self-efficacy (i.e., confidence in the ability to be physically active). Gender-stratified bivariate and multivariable random effects models were estimated to account for within-site clustering. Most participants reported feeling safe during the day, while just over one-third (36%) felt safe at night. We found no association between daytime safety reports and physical activity among both men and women. There was also no association between night-time safety reports and physical activity among men (p = 0.23) but women who reported feeling unsafe (versus safe) at night showed significantly fewer steps per day (4,302 versus 5,178, p = 0.01). Perceiving one's neighborhood as unsafe during the day was associated with significantly lower odds of having high physical activity self-efficacy among both men (OR 0.40, p = 0.01) and women (OR 0.68, p = 0.02). CONCLUSIONS Residing in a neighborhood that is perceived to be unsafe at night is a barrier to regular physical activity among individuals, especially women, living in urban low-income housing. Feeling unsafe may also diminish confidence in the ability to be more physically active. Both of these factors may limit the effectiveness of physical activity promotion strategies delivered in similar settings.

Abstract
OBJECTIVE Rural women have limited exercise opportunities and significant barriers to engaging in physical activity. This study assessed the effect of a brief primary care based walking intervention in rural women. METHODS The participants were recruited in March, 2003 by a primary care nurse at three locations in rural Missouri. The enrolled subjects were given a pedometer, exercise videotape and provided exercise counseling at intake and four time points over 6 months. The week 1 pedometer step counts were compared with step counts at 6-month follow-up. RESULTS Of the initial 75 participants, 61 completed at least one follow up encounter. The participant's mean age was 42.5 years. At intake, the majority of women (90%) exhibited one or more risk factors for cardiovascular disease; 78% were obese or overweight. Although most (62%) women reported being physically active, the mean pedometer reading was low at 6337 steps per day at week 1. Over the follow-up period, participants increased their step counts by a mean of 2573 steps per day (p<.001). Increases in step counts were seen in normal weight, overweight and obese participants. CONCLUSIONS A simple walking intervention through a primary care practice was effective in increasing the short term walking rates of rural women.

Abstract
OBJECTIVES We evaluated the association between television viewing and pedometer-determined physical activity among predominantly racial/ethnic minority residents of low-income housing in metropolitan Boston in 2005. METHODS We used mixed models to analyze the association between reported hours of television viewing and pedometer-determined steps per day among 486 adults. We also examined whether television viewing was associated with the achievement of 10000 steps per day. RESULTS There was a mean 3.6 hours of average daily television watching. In multivariable analyses, each hour of television viewing on an average day was associated with 144 (95% confidence interval [CI]= -276, -12) fewer steps per day and a decreased likelihood of accumulating 10,000 steps per day (odds ratio [OR]=0.84; 95% CI=0.71, 0.99). Weekday and weekend television viewing were each also associated with fewer steps per day. CONCLUSIONS Average daily television viewing was associated with reductions in total pedometer-determined physical activity levels (approximately 520 steps per day) in this lower-income sample. As part of a comprehensive physical activity promotion plan, recommendations to reduce television viewing should be made.
