Patients with juvenile idiopathic arthritis (JIA) are less physically active than healthy peers. Therefore, we developed an Internet-based intervention to improve physical activity (PA). The aim of this study was to examine the effectiveness of the program in improving PA. PA was determined by activity-related energy expenditure, PA level, time spent on moderate to vigorous PA, and the number of days with > or =1 hour of moderate to vigorous activity, and was assessed with a 7-day activity diary. Aerobic exercise capacity was assessed by means of a Bruce treadmill test and was recorded as maximum endurance time. Disease activity was assessed by using the JIA core set. Adherence was electronically monitored. Of 59 patients, 33 eligible patients were included and randomized in an intervention (n = 17, mean +/- SD age 10.6 +/- 1.5 years) or control waiting-list group (n = 16, mean +/- SD age 10.8 +/- 1.4 years). All patients completed baseline and T1 testing. PA significantly improved in both groups. Maximum endurance time significantly improved in the intervention group but not in the control group. In a subgroup analysis for patients with low PA (intervention: n = 7, control: n = 5), PA improved in the intervention group but not in the control group. The intervention was safe, feasible, and showed a good adherence. An Internet-based program for children with JIA ages 8-12 years directed at promoting PA in daily life effectively improves PA in those patients with low PA levels. It is also able to improve endurance and it is safe, feasible, and has good adherence.

Kane, Kyra J; Staples, Kerri L

2016-01-01

Children with coordination difficulties are at risk of low levels of physical activity (PA) participation. This intervention examined the effects of a multidisciplinary program that emphasized parent participation on motor skill performance and PA. Ten boys (5-7 years) completed a group program consisting of conditioning exercises and activities designed to address child-selected goals. Motor proficiency and PA participation were assessed before and after the program using the Test of Gross Motor Development (TGMD-2) and triaxial accelerometers, respectively. Rating scales captured child and parent perceptions of performance for each child's goals. TGMD-2 subtest raw scores, age equivalent and percentile scores improved, along with parent ratings of their child's performance. Six children reported skill improvements. On average, moderate to vigorous PA improved by 10 min per day although these gains were not significant. Time spent in sedentary activities was unchanged. None of the children met the Canadian PA and sedentary behaviour guidelines. The results support effectiveness of a group program to improve gross motor performance and levels of PA in children with coordination difficulties. Gains in both of these domains also have the potential to impact quality of life and reduce health risks associated with inactivity.

The contribution of dance to daily physical activity among adolescent girls

PubMed Central

2011-01-01

Background Structured physical activity (PA) programs are well positioned to promote PA among youth, however, little is known about these programs, particularly dance classes. The aims of this study were to: 1) describe PA levels of girls enrolled in dance classes, 2) determine the contribution of dance classes to total moderate-to-vigorous physical activity (MVPA), and 3) compare PA between days with a dance class (program days) and days without a dance class (non-program days). Methods Participants were 149 girls (11-18 years) enrolled in dance classes in 11 dance studios. Overall PA was assessed with accelerometry for 8 consecutive days, and girls reported when they attended dance classes during those days. The percent contribution of dance classes to total MVPA was calculated, and data were reduced to compare PA on program days to non-program days. Data were analyzed using mixed models, adjusting for total monitoring time. Results Girls engaged in 25.0 ± 0.9 minutes/day of MVPA. Dance classes contributed 28.7% (95% CI: 25.9%-31.6%) to girls' total MVPA. Girls accumulated more MVPA on program (28.7 ± 1.4 minutes/day) than non-program days (16.4 ± 1.5 minutes/day) (p < 0.001). Girls had less sedentary behavior on program (554.0 ± 8.1 minutes/day) than non-program days (600.2 ± 8.7 minutes/day) (p < 0.001). Conclusions Dance classes contributed a substantial proportion (29%) to girls' total MVPA, and girls accumulated 70% more MVPA and 8% less sedentary behavior on program days than on non-program days. Dance classes can make an important contribution to girls' total physical activity. PMID:21816074

Regular physical activity (PA) plays an important role in improving and maintaining one's health, especially as one ages. Although many older Americans are aware of the benefits of regular PA, the majority do not participate in regular PA that meets recommended guidelines. The purpose of this study was to gain insight into the motivators, barriers, and beliefs regarding PA of independent-living older adults with easy access to fitness facilities. In this qualitative design, focus group interviews were used to explore the individual perceptions of physically active and inactive older adults regarding PA and exercise. Thirty-one older adults, over age 60 participated in focus group discussions regarding PA beliefs and behaviors. Groups were homogenous based on current PA behaviors. Demographic information was collected. Discussions were audiotaped and transcribed verbatim and deidentified. Two researchers independently coded for emergent themes. Interrater reliability was established (κ = 0.89). Peer review was used to further ensure trustworthiness and credibility. No significant differences were noted in age, body mass index, or educational levels between the physically active and inactive groups. Differences in perceptions were noted between the groups regarding the construct of PA, barriers to participation in regular PA, and the components of an ideal PA program. Physically inactive persons had much lower fitness expectations of a physically active older adult, more perceived barriers to regular PA, and required individual tailoring of a PA program if they were going to participate. In addition, inactive persons were intimidated by the fitness facilities and concerned about slowing others down in a group exercise setting. Both groups shared similar motivators to participate in PA, such as maintaining health and socialization; however, inactive persons also described PA as needing to be purposeful and fun. Physically inactive persons perceived themselves to be physically active, as their perception of PA was grounded in a social context. Although both groups shared some barriers to regular PA participation, physically active individuals developed strategies to overcome them. Issues relating to self-efficacy and stages of change need to be explored to address the individual perceptions and needs of inactive older adults if initiation or long-term adherence to a PA program is to be achieved.

After-school hours are considered critical for children's physical activity (PA) and sedentary behaviors (SB); however, whether the after-school setting influences children's activity patterns is unknown. This study examined the influence of after-school setting (i.e., parent report of the child's usual after-school setting) on 5th grade children's PA and SB, and differences by race/ethnicity. Boys whose parents reported they usually attended an after-school program had higher PA than boys who usually went home after school. A significant interaction between race/ethnicity and after-school setting showed that minority girls whose parents reported they usually attended an after-school program had higher PA and engaged in less SB compared with those who usually went home, whereas the activity patterns of white girls did not differ by after-school setting. Children's usual after-school setting affects their activity patterns; after-school programs may potentially increase PA in boys and minority girls. Copyright © 2012 Elsevier Ltd.

To examine family child care home (FCCH) providers' perceptions of appropriate physical activity (PA), current practices, and perceived barriers to inclusion of PA within their programs. A trained facilitator lead 4 focus group sessions of FCCH providers. Questions addressed providers' planning for PA, resources and barriers, and perceptions of children's engagement. Family child care homes. 32 FCCH providers (100% female) caring for children 6 weeks to 5 years old in predominantly mixed-age programs. Types of and extent to which PA was offered for children and perceived barriers to PA in this setting. Authors coded and analyzed transcriptions based on a socioecological framework using qualitative data analysis software. Majority of providers reported running and dancing to music as the most common PA, generally in an unstructured context. Frequency varied from none to twice a day. Few providers reported planning intentionally for PA; any plans followed children's interests. Barriers to inclusion of PA included personal, programming, parent, environmental, and financial reasons. Providers requested training on PA, particularly ideas for experiences in mixed-age groups. Type, frequency, consistency, and duration of PA among FCCH homes vary widely. Implications include training on PA and resources tailored to the unique characteristics of family child care homes.

2017-11-10

Despite health benefits of physical activity (PA) and risks of physical inactivity, many older adults do not accumulate sufficient levels of PA to achieve associated health benefits. Lack of PA enjoyment may be a barrier to PA participation. Combining simulated laughter and PA for strength, balance, and flexibility is a potential solution for helping older adults maintain independence in activities of daily living through enjoyable participation in PA. The purpose of this study is to assess whether combining simulated laughter exercises with a moderate-intensity strength, balance, and flexibility PA program (i.e., LaughActive) increases participation in PA, health, and self-efficacy for PA among older adults residing in 4 assisted living facilities (ALFs). The 12-week wait list control pilot study used pre- and 6-week post-intervention comparisons within and between groups identified by paired sample t-test results among those who participated in twice-weekly LaughActive classes (n = 27). Significant improvements (p < .05-.10) were observed in mental health (SF-36v2), aerobic endurance (2-minute step test), and self-efficacy for exercise (OEE). PA programs that elicit positive emotions through simulated laughter have the potential to improve health, physical performance, and self-efficacy for PA among older adults and may positively influence participant adherence. © The Author 2016.

Schools represent an important environment for physical activity (PA) promotion among youth. Schools can promote PA through policies and programs but our understanding of how these school characteristics associate with student PA levels is largely unknown. Developing this understanding is critical for implementing new prevention interventions. The aim of this study was to identify the school- and student-related characteristics associated with moderate and high levels of PA in a sample of Ontario elementary schools. Using multi-level logistic regression analyses, we explored the school- and student-level characteristics associated with being moderately and highly active using data collected from administrators and from students in grades 5 to 8 at 30 elementary schools in Ontario. Students' PA levels, sex, grade, and the number of physical education classes per week were linked to school environment data--specifically, a school's chosen implementation model for daily physical activity and whether it offers intramural and interschool PA programming. Findings indicate that there was significant between-school variation for being moderately and highly active. Students were less likely to be moderately or highly active if they attended a school offering interschool PA programming. An important student characteristic positively associated with student PA levels included participating in at least two physical education classes per week. The residual differences in PA by school suggest that school-level characteristics facilitate higher levels of student PA beyond individual-level factors. Although most variation in student PA lies between students within schools, there is sufficient between-school variation to be of interest to practitioners and policy-makers.

Tens of millions of children regularly participate in out-of-school-time (OST) programs, providing an opportunity for child health promotion. Most research on OST has focused on structured, staff-led after-school programs, as opposed to volunteer-led programs such as enrichment programs and youth sports. The aim of this study was to describe snacks, beverages, and physical activity (PA) practices in volunteer-led OST programs across five organizations in three states. An online survey including the Out-of-School-Time Snacks, Beverages, and Physical Activity Questionnaire was distributed to 1,695 adult leaders of enrichment and youth sports programs serving 5-12 year-old children in Maine, Massachusetts, and New Hampshire, USA. The response rate was 57.8%, with 980 leaders participating and 698 (136 youth sports, 562 enrichment) remaining after data cleaning procedures. Frequencies were calculated to describe snack, beverage, and PA offerings during typical meetings and whether healthy snack, beverage, and PA criteria were met. Criteria were developed a priori with the intent to capture co-occurring practices that together indicate healthy snack (fruits and vegetables or no snack over salty/sweet snacks); beverage (water over sugar-sweetened beverages); and PA environments (regular opportunities for >15 or 45 min of PA in enrichment and sports programs, respectively). About half of enrichment leaders reported that snacks and beverages were provided during typical meetings vs. one-fifth of sports leaders. In 28.4% of enrichment programs, PA was offered at every meeting vs. 98.5% of sports programs. Among enrichment programs, 50.4 and 25.8% met healthy snack and beverage criteria, respectively, and 29.4% met PA criteria, with 27.6% meeting criteria in two or more areas, and 5.0% in all three. Among sports programs, 72.8 and 78.7% met healthy snack and beverage criteria, respectively, and 71.3% met PA criteria. Eighty-two percent met criteria in two or more areas, and 46.3% met criteria in all three. Most programs did not meet criteria for healthier snacks and beverages and opportunities for PA during typical meetings, indicating room for improvement in encouraging widespread adoption of these practices. Efforts to improve the healthfulness of snacks and beverages and increase opportunities for PA during volunteer-led OST programs are warranted.

Physical activity (PA) is critical to preventing childhood obesity and contributes to children's overall physical and cognitive health, yet fewer than half of all children achieve the recommended 60 min per day of moderate-to-vigorous physical activity (MVPA). Schools are an ideal setting to meeting PA guidelines, but competing demands and limited resources have impacted PA opportunities. The Fueling Learning through Exercise (FLEX) Study is a randomized controlled trial that will evaluate the impact of two innovative school-based PA programs on children's MVPA, cognitive function, and academic outcomes. Twenty-four public elementary schools from low-income, ethnically diverse communities around Massachusetts were recruited and randomized to receive either 100 Mile Club® (walking/running program) or Just Move™ (classroom-based PA program) intervention, or control. Schoolchildren (grades 3-4, approximately 50 per school) were recruited to participate in evaluation. Primary outcome measures include PA via 7-day accelerometry (Actigraph GT3X+ and wGT3X-BT), cognitive assessments, and academic achievement via state standardized test scores. Additional measures include height and weight, surveys assessing psycho-social factors related to PA, and dietary intake. School-level surveys assess PA infrastructure and resources and intervention implementation. Data are collected at baseline, mid-point (5-6 months post-baseline), and post-intervention (approximately 1.5 years post-baseline). Demographic data were collected by parents/caregivers at baseline. Mixed-effect models will test the short- and long-term effects of both programs on minutes spent in MVPA, as well as secondary outcomes including cognitive and academic outcomes. The FLEX study will evaluate strategies for increasing children's MVPA through two innovative, low-cost, school-based PA programs as well as their impact on children's cognitive functioning and academic success. Demonstration of a relationship between school-based MVPA with neutral or improved, rather than diminished, academic outcomes in a naturalistic environment has the potential to positively influence investment in school PA programs and initiatives.

The majority of research on factors associated with women participation in physical activity (PA) has been in developed countries with limited research in developing countries. Few women in Malaysia are active at the recommended levels for health, and activity rates are less than developed countries. Little research has focused specially on physically active Malaysian women and the factors that contribute to them becoming and staying active in PA programs. This lack of knowledge hinders the tailored development and implementation of PA programs to meet their needs. The aim of this study was to identify the factors of participation in PA programs for Malaysian women. The social-ecological model was used to investigate and theme the factors. Focus group discussion was conducted with participants in six PA programs targeted specifically to women. Thirty-seven women were involved in the focus group discussion, with ages ranging from 19 to 82 years. Inductive and deductive content analysis was conducted from verbatim transcripts using NVivo. Inductive content analysis allowed raw data and second-order themes to emerge. Findings revealed social support structures, tailored programs for women, and location were key contributors that encouraged women to participate in these programs. The similarity in contributors between women in non-western and western countries signifies a prime opportunity for bi-lateral relationships to be formed to enable the enhancement of program development relevant to different ethnicities and cultures within or across countries. © The Author 2017.

A multi-level examination of school programs, policies and resources associated with physical activity among elementary school youth in the PLAY-ON study

PubMed Central

2010-01-01

Background Given the decline in physical activity (PA) levels among youth populations it is vital to understand the factors that are associated with PA in order to inform the development of new prevention programs. Many studies have examined individual characteristics associated with PA among youth yet few have studied the relationship between the school environment and PA despite knowing that there is variability in student PA levels across schools. Methods Using multi-level logistic regression analyses we explored the school- and student-level characteristics associated with PA using data from 2,379 grade 5 to 8 students attending 30 elementary schools in Ontario, Canada as part of the PLAY-Ontario study. Results Findings indicate that there was significant between-school random variation for being moderately and highly active; school-level differences accounted for 4.8% of the variability in the odds of being moderately active and 7.3% of the variability in the odds of being highly active. Students were more likely to be moderately active if they attended a school that used PA as a reward and not as discipline, and students were more likely to be highly active if they attended a school with established community partnerships. Important student characteristics included screen time sedentary behaviour, participating in team sports, and having active friends. Conclusion Future research should evaluate if the optimal population level impact for school-based PA promotion programming might be achieved most economically if intervention selectively targeted the schools that are putting students at the greatest risk for inactivity.

After-school programs may provide valuable opportunities for children to accumulate healthful physical activity (PA). This study assessed the PA of third-, fourth-, and fifth-grade children in the Keep It Moving! (KIM) after-school PA program, which was implemented in an ethnically diverse and low socioeconomic status school district in Colorado Springs, Colorado. The PA of KIM participating children (N = 116) at 4 elementary schools was objectively assessed using ActiGraph accelerometers and the System for Observing Fitness Instruction Time (SOFIT). Linear mixed-effects models or generalized linear mixed-effects models were used to compare time spent in sedentary (SED) behaviors, light PA (LPA), moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) between genders and weight status classifications during KIM sessions. Children accumulated 7.6 minutes of SED time, 26.9 minutes of LPA, and 22.2 minutes of MVPA during KIM sessions. Boys accumulated less SED time (p < .05) and LPA (p = .04) than girls, but accumulated more MPA (p = .04), VPA (p = .03), and MVPA (p = .03). Overweight/obese children accumulated more LPA (p = .04) and less VPA (p < .05) than nonoverweight children. SOFIT data indicated that children spent a considerable proportion of KIM sessions being very active (12.4%), walking (36.0%), or standing (40.3%). The KIM program provides opportunities for disadvantaged children to accumulate substantial amounts of MVPA (>20 minutes per session) in an effort to meet current PA guidelines. © 2013, American School Health Association.

Effective and sustainable intervention programs are needed to promote physical activity (PA) in children. To adapt the NASA Mission X: Train Like an Astronaut program for use with South Korean children, and to evaluate its feasibility and effectiveness for promoting children's physical fitness. Children 5 years old ( n = 212) and their parents were recruited from three kindergartens in three cities to participate in a 6-week intervention program in fall 2014. We assessed the children's PA and related changes, and parental changes in attitude and beliefs, after participation in the intervention. Girls reported less PA than boys (40.7 vs. 59.0, p < 0.01). Children with a normal body mass index (BMI) were more likely to be active than underweight children (< 10 percentile) or overweight children (⩾ 85 percentile). After the intervention, about one-half of the children had increased their level of PA (49.4%), increased interest in PA (59.1%) and found psychological need satisfaction in exercise (52.6%). The majority of parents became aware of the necessity of childhood PA (94.2%), their child's PA capability (64.3%), and the relationship of PA with their children's self-esteem (79.9%). The adapted NASA Mission X program was feasible and effective in promoting PA in kindergarteners, and also improved their parents' attitude and beliefs about children's PA in South Korea. This study provided a model for promoting childhood health through child care and educational settings.

The Invisible Employee: University Housekeeping Employees' Perceptions of Physical Activity.

Das, Bhibha M; Sartore-Baldwin, Melanie; Mahar, Matthew T

2016-09-01

A significant literature links race and socioeconomic status with physical inactivity and negative health outcomes. The aim of this study was to explore physical activity (PA) perceptions of an underserved, lower socioeconomic minority sector of the workforce. Two focus groups were conducted to examine university housekeepers' perceptions of physical activity. Demographic and anthropometric data were also obtained. Participants (N = 12; 100% female, 100% African-American) overwhelmingly associated PA with traditional exercise (eg, going to a gym). The most important barrier to PA was the perception of being active on the job, thus not needing to do leisure time PA. The most important perceived benefit to PA was improvement of physical and mental health. Employees perceived that a university investment in employees' health might improve morale, especially within low-pay employee sectors where low levels of job satisfaction may be present. Although perceived benefits to PA in this population are consistent with other employee sectors, perceived barriers to PA may be unique to this sector of the workforce. PA promotion programs should focus on providing resources as well as guidelines that demonstrate the need for PA outside of the workplace setting. Such programs may improve employee health, morale, and productivity.

Afterschool programs (ASPs) have become increasingly recognized as a key context to support youth daily physical activity (PA) accrual. The purpose of the present study was to assess the physical and social-motivational climate characteristics of ASPs associated with youth PA, and variations in contextual correlates of PA by youth sex. Systematic observations of 7 ASPs serving underserved youth (minority, low income) was conducted using the System for Observing Play and Leisure Activity in Youth and a social-motivational climate observation tool founded on self-determination theory. For five program days at each site, teams of two coders conducted continuous observations of youth PA (sedentary, moderate, vigorous), five physical features (e.g., equipment availability), eight staff interactions (e.g., encourage PA), and seven motivational climate components (e.g., inclusive). Aligned with previous research, regressions controlling for variations by site indicated that organized PA, provision of portable equipment, and staff PA participation and supervision are key correlates of youth PA. Moreover, as the first study to systematically observe motivational-context characteristics of ASPs, we identified several key modifiable motivational features that are necessary to address in order to increase youth engagement in PA during the out-of-school hours. Among motivational features assessed, "relatedness" components (positive peer relations, inclusive/cooperative activities) were primary correlates of girls' PA. In contrast, all three motivational features specified by self-determination theory (support for autonomy, mastery/competence, and inclusion/relatedness) were correlated with boys' PA. Findings are discussed in terms of policy and practice for understanding strengths and needs of ASPs to effectively engage youth in PA. © 2015 Society for Public Health Education.

A Community-Based Exergaming Physical Activity Program Improves Readiness-to-Change and Self-Efficacy Among Rural-Residing Older Adults.

2017-07-01

Rural-residing older adults (OA) are not meeting physical activity (PA) recommendations, such that identifying methods of increasing PA among OA remains an ongoing challenge. This study evaluated the effect of a community-based exergaming program on PA readiness-to-change and self-efficacy among rural-residing OA (n = 265). There was a significant (p = .008) increase in readiness-to-change classification from PRE to POST. Significant increases in self-efficacy, or confidence in their ability to be physically active for a prescribed period of time, were detected for 35 (p = .011) and 40 min (p = .035) of continuous PA. PA self-efficacy change for 35 min of continuous PA (F [3,137] = 3.973, p = .010) and 40 min of continuous PA (F [3,137) = 2.893, p = .038) were influenced by the interaction between PRE self-reported health and PRE PA readiness-to-change levels. Results suggest that an exergaming-themed PA intervention is effective at increasing PA participation and self-efficacy for PA among rural-residing OA.

Traditional physical activity (PA) programs have not been effective in increasing PA in African American girls. Currently, there is limited information regarding the components of PA programs that drive participation in African American girls. The purpose of our investigation was to describe the facilitators, barriers, and components of a culturally tailored afterschool PA program that will potentially inspire the participation of African American mother-daughter dyads. Six focus groups (n=12 mother-daughter dyads; daughters, 7-10 yrs in age) were conducted between March and May 2012. Focus group semi-structured interviews were transcribed, coded, and systematically analyzed using NVivo. Mothers reported a preference for non-traditional (dancing, household chores) types of PA. While daughters preferred to participate in both dance-based and traditional types (walking, riding bikes) of PA. Participants felt that the use of a culturally tailored dance program would be appealing because it highlights the cultural and historical legacy of the African American culture. Mothers wanted programs that would allow them time to spend with their daughters. Top three dance styles that mothers wanted to participate in were African, hip-hop, and Salsa/samba, while daughters reported that they would enjoy participating in hip-hop, African, and jazz. The most common responses given for resources needed for participating in a culturally tailored afterschool dance program were the location of the program, transportation, and childcare for siblings. Our investigation highlights some cultural factors related to facilitators and barriers of PA that should be addressed in designing PA studies for African American girls and their mothers.

Physical activity (PA) is a key factor for facing the increasing prevalence of obesity and overweight, and should be part of every public health programs. In this context, a community-based public health program promoting PA was developed in a low-income neighborhood of the city of Saint-Denis (France). This work aimed at assessing the effectiveness of a 2-year PA promotion program. A quasi-experimental study was carried out using a pre/post design, with an assessment before (2013) and after (2015) the program. The interviewees were selected using a stratified random cluster sampling. The primary outcome was the proportion of participants practicing sufficient PA (WHO guidelines), and was measured using the RPAQ questionnaire. External interventions (on both neighborhood environment and inhabitants) were listed. We collected 199 questionnaires at baseline and 217 in 2015. There was a majority of women in both samples: 64.3 % in 2013 and 58.2 % in 2015. The average age of participants was 38.1 years (+/-1.1) and 40.6 (+/-1.1) respectively. The proportion of people practicing sufficient PA was modified from 48.1 % in 2013 to 63.5 % in 2015 (p = 0.001). This was mainly driven by women whose level of PA, increased from 40.3 % to 60.3 % (p = 0.002), reaching the average national French estimation of PA level among adults (63.5 %). This work showed a significant increase of the proportion of people practicing PA in a disadvantaged neighborhood where a community-based program promoting PA was developed. Simultaneous external interventions contributed to the results, showing the necessity of synergic interventions to reach efficiency.

Single sex after-school physical activity programs show potential to prevent unhealthy weight gain. The aim of this study was to assess the acceptability and potential efficacy of single-sex after-school physical activity programs for overweight and at-risk children from low-income communities. 7-month, 2-arm parallel-group, RCT, conducted at an elementary school in a disadvantaged area in Wollongong, Australia (March-November 2010). 20 boys and 17 girls were randomized to intervention (PA) or active comparison groups (HL). Primary outcomes included implementation, acceptability, percentage body fat and BMI z-score. The PA programs were acceptable with high implementation and enjoyment rates. At 7 months postintervention girls in the PA group displayed greater changes in percentage body fat (adjust diff. = -1.70, [95% CI -3.25, -0.14]; d = -0.83) and BMI z-score (-0.19 [-0.36, -0.03]; d= -1.00). At 7 months boys in the PA group showed greater changes in waist circumference (-3.87 cm [-7.80, 0.15]; d= -0.90) and waist circumference z-score (-0.33 [-0.64, -0.03]; d= -0.98). For both boys' and girls' PA groups, changes in adiposity were not maintained at 12-month follow-up. Single-sex after-school physical activity programs are acceptable and potentially efficacious in preventing unhealthy weight gain among overweight and at-risk children. However improvements are hard to sustain once programs finish operating.

Lifestyle modification programs improve several health-related behaviors, including physical activity (PA) and nutrition. However, few of these programs have been expanded to impact a large number of individuals in one setting at one time. Therefore, the purpose of this study was to determine whether a PA- and nutrition-based lifestyle modification program could be effectively conducted using a large group format in a community-based setting. One hundred twenty-one participants enrolled in a 16-week, community-based lifestyle modification program and separated in small teams of 13 to 17 individuals. Height, weight, fruit and vegetable (FAV) consumption, physical fitness, and several psychosocial measures were assessed before and after the program. Significant improvements in 6-minute walk distance (+68.3 m; p < .001), chair stands (+6.7 repetitions; p < .001), FAV servings (+1.8 servings/day; p < .001), body weight (-3.2 lbs; p < .001), as well as PA social support and eating habits self-efficacy were observed. Our lifestyle modification program was also successful in shifting participants to higher levels of stages of change for nutrition and PA, increasing overall levels of self-efficacy for healthy eating, and improving levels of social support for becoming more active. A lifestyle modification program can be successfully implemented in a community setting using a large group format to improve PA and FAV attitudes and behaviors.

Decreasing daily life physical activity (PA) outside an exercise program might hinder the benefit of that program on lower-extremity physical function (LEPF) in older adults. The purpose of this study was to investigate how daily life PA modulates the effects of an exercise program on LEPF. The participants were 46 community-dwelling older adults (mean age, 70.1 ± 3.5 years) in Kasama City, a rural area in Japan. All participated in a fall-prevention program called square-stepping exercise once a week for 11 weeks. We evaluated their daily life PA outside the exercise program with pedometers and calculated the average daily step counts during the early and late periods of the program. We divided participants into 2 groups on the basis of whether or not they decreased PA by more than 1000 steps per day between the early and late periods. To ascertain the LEPF benefits induced by participating in the exercise program, we measured 5 physical performance tests before and after the intervention: 1-leg stand, 5-time sit-to-stand, Timed Up and Go (TUG), habitual walking speed, and choice-stepping reaction time (CSRT). We used a 2-way analysis of variance to confirm the interaction between the 2 groups and the time effect before and after the intervention. During the exercise program, 8 participants decreased their daily life PA (early period, 6971 ± 2771; late period, 5175 ± 2132) and 38 participants maintained PA (early period, 6326 ± 2477; late period, 6628 ± 2636). Both groups significantly improved their performance in TUG and CSRT at the posttest compared with the baseline. A significant group-by-time interaction on the walking speed (P = .038) was observed: participants who maintained PA improved their performance more than those who decreased their PA. Square-stepping exercise requires and strengthens dynamic balance and agility, which contributed to the improved time effects that occurred in TUG and CSRT. On the contrary, because PA is positively associated with walking speed, maintaining daily life PA outside an exercise program may have a stronger influence on walking speed. To enhance the effectiveness of an exercise program for young-old adults, researchers and instructors should try to maintain the participant's daily life PA outside the program. Regardless of decreasing or maintaining daily life PA, the square-stepping exercise program could improve aspects of LEPF that require complex physical performance. However, a greater effect can be expected when participants maintain their daily life PA outside the exercise program.

Physical activity (PA) and exercise is increasingly being recognised as an efficacious component of treatment for various mental disorders. The association between PA and cardiometabolic disease is well established, as is the strong link between mental illness, sedentary behaviour and poor cardiometabolic health. Examples of successful integration of clinical PA programs within mental health treatment facilities are increasing. The aim of this review was to summarise the evidence regarding PA and mental illness, and to present examples of clinical exercise programs within Australian mental health facilities. A narrative synthesis of systematic reviews and clinical trials was conducted. Evidence supporting the inclusion of PA programs as an adjunct to treatment for various conditions was presented; including depression, schizophrenia, anxiety disorders, post-traumatic stress disorder and substance abuse. In light of the available evidence, the inclusion of clinical PA programs within mental health treatment, facilitated by dedicated clinicians (exercise physiologists / physiotherapists) was justified. PA is a feasible, effective and acceptable adjunct to usual care for a variety of mental disorders. There is a clear need for greater investment in initiatives aiming to increase PA among people experiencing mental illness, given the benefits to both mental and physical health outcomes. © The Royal Australian and New Zealand College of Psychiatrists 2015.

A quasi-experimental cluster-controlled design was used to test the impact of comprehensive school physical activity program (CSPAP) professional development on changes in school physical activity (PA) offerings, moderate-to-vigorous physical activity (MVPA) and sedentary behaviors of 9-14 year-old children during school. Two groups of Louisiana elementary and middle school physical education teachers (N=129) attended a CSPAP summer workshop (95 in 2012=intervention, 34 in 2013=control) and were assessed on school PA offerings (teacher-reported; pre, mid, and post). During the 2012-2013 school year, intervention teachers received CSPAP support while implementing new school PA programs. MVPA and sedentary behaviors were assessed (accelerometry; baseline and post) on a sample of 231 intervention, 120 control students from 16 different schools. Multivariate analysis of covariance indicated that intervention teachers reported significantly more PA offerings during school (3.35 vs. 2.37) and that involve staff (1.43 vs. 0.90). Three-level, mixed model regressions (stratified by sex) indicated that students overall spent less time in MVPA and more time being sedentary during school, but the effects were significantly blunted among intervention students, especially boys. This study provides preliminary evidence for CSPAP professional development programs to influence school-level PA offerings and offset student-level declines in MVPA and increases in sedentary behavior.

2014-06-01

Older people with intellectual disability (ID) are characterized by low physical activity (PA) levels. PA is important for reducing health risks and maintaining adequate fitness levels for performing activities of daily living. The aim of this study was to explore preferences of older adults with ID for specific physical activities, and to gain insight into facilitators and barriers to engaging into PA. Fourteen in-depth interviews and four focus groups were undertaken, with a total of 40 older adults with mild and moderate ID included in the analysis. NVivo software was used for analysing the transcribed verbatim interviews. In total, 30 codes for facilitators and barriers were identified. Themes concerning facilitators to PA were enjoyment, support from others, social contact and friendship, reward, familiarity, and routine of activities. Themes concerning barriers to PA were health and physiological factors, lack of self-confidence, lack of skills, lack of support, transportation problems, costs, and lack of appropriate PA options and materials. The results of the present study suggest that older adults with ID may benefit from specific PA programs, adapted to their individual needs and limitations. Results can be used for developing feasible health promotion programs for older adults with ID.

To objectively measure the physical activity (PA) levels of children attending family day care programs. A total of 114 children from 47 family day care centers wore an accelerometer for the duration of their time in care. Time in moderate-to-vigorous PA (MVPA) and total PA was calculated using previously validated cut points. Children accumulated 5.8 ± 3.2 minutes of MVPA and 10.4 ± 4.4 minutes of total PA per hour of attendance. Boys exhibited significantly higher levels of PA than girls. Among healthy weight children, 4- and 5-year-olds exhibited significantly higher levels of PA than 2- and 3-year-olds. Overweight and obese 4- and 5-year-olds exhibited significantly lower levels of PA than their healthy weight counterparts. Children attending family day care participate in low levels of PA during the child care day. The results highlight the need for effective programs to promote PA in family day care.

Objectives Traditional physical activity (PA) programs have not been effective in increasing PA in African-American girls. Currently, there is limited information regarding the components of PA programs that drive participation in African-American girls. The purpose of this investigation was to describe the facilitators, barriers, and components of a culturally-tailored afterschool PA program that will potentially inspire the participation of African-American mother-daughter dyads. Methods Six focus groups (n=12 mother-daughter dyads; daughters, 7–10 yrs in age) were conducted between March and May 2012. Focus group semi-structured interviews were transcribed, coded, and systematically analyzed using NVivo. Results Mothers reported a preference for non-traditional (dancing, household chores) types of PA. While daughters preferred to participate in both dance-based and traditional types (walking, riding bikes) of PA. Participants felt that the use of a culturally-tailored dance program would be appealing because it highlights the cultural and historical legacy of the African-American culture. Mothers wanted programs that would allow them time to spend with their daughters. Top three dance styles that mothers wanted to participate in were African, Hip-hop, and Salsa/samba. While, daughters reported that they would enjoy participating in Hip-hop, African, and Jazz.

Background Despite a large evidence base to demonstrate the health benefits of regular physical activity (PA), few physicians incorporate PA counseling into office visits. Inadequate medical training has been cited as a cause for this. This review describes curricular components and assesses the effectiveness of programs that have reported outcomes of PA counseling education in medical schools. Methods The authors systematically searched MEDLINE, EMBASE, PsychINFO, and ERIC databases for articles published in English from 2000 through 2012 that met PICOS inclusion criteria of medical school programs with PA counseling skill development and evaluation of outcomes. An initial search yielded 1944 citations, and 11 studies representing 10 unique programs met criteria for this review. These studies were described and analyzed for study quality. Strength of evidence for six measured outcomes shared by multiple studies was also evaluated, that is, students’ awareness of benefits of PA, change in students’ attitudes toward PA, change in personal PA behaviors, improvements in PA counseling knowledge and skills, self-efficacy to conduct PA counseling, and change in attitude toward PA counseling. Results Considerable heterogeneity of teaching methods, duration, and placement within the curriculum was noted. Weak research designs limited an optimal evaluation of effectiveness, that is, few provided pre-/post-intervention assessments, and/or included control comparisons, or met criteria for intervention transparency and control for risk of bias. The programs with the most evidence of improvement indicated positive changes in students’ attitudes toward PA, their PA counseling knowledge and skills, and their self-efficacy to conduct PA counseling. These programs were most likely to follow previous recommendations to include experiential learning, theoretically based frameworks, and students’ personal PA behaviors. Conclusions Current results provide some support for previous recommendations, and current initiatives are underway that build upon these. However, evidence of improvements in physician practices and patient outcomes is lacking. Recommendations include future directions for curriculum development and more rigorous research designs.

Rural Americans engage in less physical activity (PA) and experience higher rates of consequent health problems (i.e., obesity, cardiovascular disease) than urban Americans. Although geographic barriers have historically made this population hard to reach, rural individuals are increasingly gaining access to smartphones. Thus, the purpose of this study was to evaluate PA behavior and barriers to PA among rural residents and to gauge their receptiveness to a smartphone-based PA intervention that is currently in the development stage. Rural Floridian adults (n=113), 18 years of age and older, completed surveys to assess PA behavior, PA barriers, and opinions about an intervention to increase PA. Specifically, they were asked to imagine a program that would require them to do PA with their mobile phones and whether they viewed intended aspects of the program as helpful. The present work is therefore formative research that sought to determine the feasibility and acceptability of a smartphone-based intervention among rural residents. RESULTS of the survey will inform the development of a tailored, smartphone-based PA intervention. The 37.2% of participants with low PA levels (<600 metabolic equivalent [MET]-min per week) were more likely to report personal and environmental barriers to PA than the 47.8% of participants with moderate PA levels (≥600 MET-min per week). More barriers were reported among participants who self-reported as white and among participants of older age, lower education level, and lower socioeconomic status. Additionally, 75.9% of participants reported features of the intervention as at least somewhat helpful. The growing ubiquity of smartphones among rural residents, combined with participants' positive response to the program description, supports the acceptability of a smartphone-based PA intervention for rural communities. Given the participants' receptiveness, future research should evaluate the efficacy of smartphone-delivered health behavior interventions among this population.

Little evidence exists on health care provider (HCP) prescriptions for children’s outdoor physical activity (PA). Semistructured interviews were conducted with 15 children’s HCPs to explore perspectives on outdoor PA prescription programs for children and barriers to implementation. Thematic analytic techniques were used to analyze the data. Most participants reported an awareness of health benefits to children being in the outdoors. Ten themes emerged from the data related to 3 thematic categories: (1) current strategies that HCPs are using to promote PA among children, (2) barriers that HCPs see to prescribing outdoor PA, and (3) potential strategies for promoting outdoor PA among children. Assessment of the local outdoor PA environment and resource development must be done prior to a prescription program. HCPs should be skilled in conducting conversations and setting goals related to outdoor PA tailored to the patient. Developing a system for follow-up with patients on established goals should also be included. PMID:29152542

Physical activity (PA) is ranked as a leading health indicator and the workplace is a key setting to promote PA. The purpose of this study was to examine how goal-setting and exercise self-efficacy (SE) during a health promotion program influenced PA level among Japanese workers. Using a cross-sectional study design, we surveyed 281 employees. The short version of the International Physical Activity Questionnaire was used to assess PA level. Exercise SE was assessed using a partially modified version of Oka's exercise SE scale. Personal goals were assessed as the total numbers of "yes" responses to five items regarding "details of personal goals to perform PA". A mediational model was used to examine whether exercise SE mediates between the number of personal goals and PA level. The mean age of the participants was 46.3 years, 76.2% were men, and the most common occupational category was software engineer (30.6%). The average PA level per week exceeded the recommended level in 127 participants (45.2%). One hundred and eighty-four participants (65.5%) set some form of concrete personal goal to perform PA. The relationship between the number of personal goals and PA level was mediated by exercise SE. Our study showed that exercise SE mediates goal-setting and increases PA. The results suggest that the components of PA promotion programs should be tailored to enhance participants' confidence in performing PA.

Interventions on adolescents' lifestyle are important, but the main mechanisms that explain the changes (mediating variables) on lifestyle are unclear. This paper presents the rationale and methods of an intervention program focused on promoting active and healthy lifestyles (especially physical activity [PA] practice and reducing screen time) among Brazilian students-the Fortaleça sua Saúde program (Portuguese for "strengthen your health"). This is a school-based cluster-randomized controlled trial. Three intervention and three control (no intervention) full-time public schools were randomly selected in Fortaleza, northeastern Brazil. Students (n = 1,272) from classes in Grades 7-9 were eligible, and 1,085 (548 in the intervention and 537 in control schools) completed the baseline and follow-up measures. The program duration was approximately four months and took place in 2014. Intervention strategies focused on teacher training, activities on health in the curriculum, active opportunities in the school environment (the availability of equipment for PA), and health education (health materials for students and parents). Data collection was undertaken before and immediately after the intervention. The primary variables included the practice of PA (weekly PA volume, PA behavior change stage and preference for PA during leisure-time) and screen time (TV and computer/video games). Potential intrapersonal, interpersonal and environmental mediators of PA and screen time were evaluated by a standardized questionnaire. Other lifestyle components (e.g., eating habits, substance use), psychological (e.g., self-rated health, body satisfaction) and biological (general and abdominal obesity) aspects, as well as academic performance were also evaluated in the total sample. Depressive symptoms, eating disorders, sleep quality, objectively-measured PA, and sedentary time were evaluated in obese students. If effective, this program will contribute to the development of public policies for the promotion of active and healthy lifestyles in youth, especially those from low- and middle-income countries. The main intrapersonal, interpersonal and/or environmental mediators of PA and screen time may also be indicated. Finally, we anticipate that the proposed strategies may be adaptable to public schools and may even be extended to the entire school system. ClinicalTrials.Gov: NCT02439827 .

Project Analysis and Integration (PA&I) performed planning and integration activities to support management of the various Flat-Plate Solar Array (FSA) Project R&D activities. Technical and economic goals were established by PA&I for each R&D task within the project to coordinate the thrust toward the National Photovoltaic Program goals. A sophisticated computer modeling capability was developed to assess technical progress toward meeting the economic goals. These models included a manufacturing facility simulation, a photovoltaic power station simulation and a decision aid model incorporating uncertainty. This family of analysis tools was used to track the progress of the technology and to explore the effects of alternative technical paths. Numerous studies conducted by PA&I signaled the achievement of milestones or were the foundation of major FSA project and national program decisions. The most important PA&I activities during the project history are summarized. The PA&I planning function is discussed and how it relates to project direction and important analytical models developed by PA&I for its analytical and assessment activities are reviewed.

Insufficient physical activity (PA) and poor physical fitness are risks for several noncommunicable diseases among working-aged men. PA programs have been launched to increase activity levels in the population but working-aged men have been underrepresented in these programs. The aim of the present cross-sectional study was to evaluate validity of a short scale for psychosocial factors among Finnish working-aged men who participated in a PA campaign. The study examined also the associations between psychosocial factors and phase of PA change across fitness groups. Physical fitness was assessed with a body fitness index constructed on the basis of a handgrip test, the Polar OwnIndex Test, and body composition analysis (InBody 720). The men were classified into low (n = 162), moderate (n = 358), and high (n = 320) body fitness index groups. Psychosocial factors and self-reported phase of PA change were assessed with a questionnaire. Psychometric properties of the scale were assessed with confirmatory factor analysis and differences between phases of PA change were examined with one-way analysis of variance. The evaluated scale included factors for self-efficacy, goal setting, skills, and social support. Good physical fitness was related to better perceived self-efficacy and ability to manage one’s PA environment. Goal setting was critical for PA change at all fitness levels. Better understanding of the interactions between psychosocial factors and PA change could help in targeting PA programs to low-fit men. Further study should examine the validity of the improved psychosocial measure. PMID:26614443

The current study evaluated physical activity (PA) level and its associated effects among students in the public network of São Paulo, Brazil. A cross-sectional study was taken using a representative sample of students in São Paulo public school system. International Physical Activity Questionnaire determined PA level. Students who reported at least 300 minutes/week of PA were considered active. The independente variables were: gender, age, body mass index, education, region, recognition of the Agita São Paulo program. The prevalence of regular PA was 71.7%. Males (PR = 1.09, 95% CIs = 1.04 -1.15) at least 17 years old (PR = 1.16, 95% CIs 1.09-1.24) in their 3rd year of high school (PR = 1.20, 95% CIs = 1.12-1.29) who resided in the Midwest region (PR = 1.27, 95% CIs 1.16-1.38) were most likely to be active. Males at least 17 years old in their 3rd year of high school who lived in the Midwest and recognized the Agita São Paulo/Agita Galera program had higher levels of PA. São Paulo students presented a high level of PA. Moreover, males older than 17 years, attending their 3rd year of high school, who lived in the Midwest region, and recognized the Agita São Paulo/Agita Galera program were the most likely to be more active.

Schools are important settings for not only providing and promoting children's physical activity (PA) but also for reducing PA disparities. We investigated associations between school-level demographic characteristics (racial/ethnic and socioeconomic composition, urban-rural status, and student-to-teacher ratio) and 16 PA-promoting practices in 347 Nevada public elementary, middle, and high schools in 2014. We found that low-cost and easy-to-implement practices are most prevalent. There is relative demographic equity in ten of 16 PA practices and significant differences in six PA practices in Nevada schools. Schools with comparatively larger percentages of Black students are the most disadvantaged, as they have the fewest PA-supportive practices in place. Higher percent black was associated with lower odds of providing classroom activity breaks (AOR=0.632, 95% CI=0.453-0.881) and bike racks (AOR=0.60, 95% CI=0.362-0.996), greater odds of withholding recess/PE for disciplinary reasons (AOR=1.377, 95% CI=1.006-1.885), and lower odds of having recess supervisors who are trained to promote PA (AOR=0.583, 95% CI=0.374-0.909). Schools with greater percentages of Hispanic students have lower odds of providing before-school PA programs (AOR=0.867, 95% CI=0.761-0.987), whereas schools with greater percentages of low-SES students have greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Higher student-to-teacher ratio was also associated with greater odds of providing after-school PA programs (AOR=1.135, 95% CI=1.016-1.268). Urban-rural status was unrelated to all PA practices.

Chronic health conditions and impaired quality of life are commonly experienced in childhood cancer survivors. While rehabilitation clinics support patients in coping with the disease, studies evaluating an inpatient rehabilitation program on promoting physical activity (PA) and health-related quality of life (HRQoL) are missing. A 4-week inpatient rehabilitation program was prospectively evaluated. One hundred fifty patients with leukemia or lymphoma (N = 86), brain tumors (N = 38), and sarcomas (N = 26) were enrolled on average 17 months after cessation of acute medical treatment. PA amount and cadence (indicating the intensity of walking activity) using the StepWatch™ 3 Activity Monitor and HRQoL global and physical well-being scores using the KINDL(®) questionnaire were assessed before, immediately after, and 6 and 12 months following the program and analyzed using multiple linear mixed models. Significant effects on PA were only found at 12-month follow-up for amount and cadence variables (all p < 0.05). While leukemia and lymphoma patients revealed the highest PA level throughout the study, rehabilitation effects were more pronounced for cadence variables in brain tumor and sarcoma patients. The rehabilitation program had immediate (t = 4.56, p < 0.001) and sustainable effects on HRQoL global scores (6-month follow-up, t = 4.08, p < 0.001; 12-month follow-up, t = 3.13, p < 0.006). Immediate and sustainable increases in HRQoL indicate that a 4-week rehabilitation program is beneficial for improving psychosocial well-being, while the significant increase in PA levels could be related to general recovery as well. The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.

The Smartphone Peer Physical Activity Counseling (SPPAC) Program for Manual Wheelchair Users: Protocol of a Pilot Randomized Controlled Trial

PubMed Central

Best, Krista L; Sweet, Shane N; Arbour-Nicitopoulos, Kelly P; Borisoff, Jaimie F; Noreau, Luc; Martin Ginis, Kathleen A

2017-01-01

Background Physical activity (PA) must be performed regularly to accrue health benefits. However, the majority of manual wheelchair users do not meet PA recommendations. Existing community-based PA programs for manual wheelchair users appear to work, but effect sizes are small and retention is low. Existing PA programs may not fully implement some psychosocial factors that are strongly linked with PA (eg, autonomy). The use of peers and mobile phone technology in the Smartphone Peer PA Counseling (SPPAC) program represents a novel approach to cultivating a PA-supportive environment for manual wheelchair users. Objective The primary objective is to compare change in objective PA between the experimental (SPPAC) and control groups from baseline to postintervention (10 weeks) and follow-up (3 months). Changes in and relationships between subjective PA, wheelchair skills, motivation, self-efficacy (for overcoming barriers to PA for manual wheelchair use), satisfaction of psychological needs for PA, and satisfaction with PA participation will be explored (secondary outcome). Program implementation will be explored (tertiary objective). Methods A total of 38 community-living manual wheelchair users (≥18 years) will be recruited in a randomized controlled trial (RCT). Participants in both the control and experimental groups will receive existing PA guidelines. Participants in the experimental group will also receive the SPPAC program: 14 sessions (~30 min) over a 10-week period delivered by a peer trainer using a mobile phone. PA activities will be based on individuals’ preferences and goals. Implementation of important theoretical variables will be enforced through a peer-trainer checklist. Outcomes for objective PA (primary) and subjective PA, wheelchair skills, motivation, self-efficacy, satisfaction of psychological needs, and satisfaction with participation will be collected at three time points (baseline, postintervention, follow-up). Multiple imputations will be used to treat missing data. A mixed-model ANCOVA will be conducted, controlling for covariates (primary and secondary objectives). The strength and direction of the relationships between the primary and secondary outcomes will be explored (secondary objective). Descriptive and content analysis will be used to appraise program implementation (tertiary objective). Results Funding has been obtained from the Craig Neilsen Foundation and the Canadian Disability Participation Project, with additional funds being sought from the Canadian Institute for Health Research and Fonds de Recherche du Québec-Santé. Pilot evaluation of intervention implementation is currently underway, with enrollment anticipated to begin early 2018. Conclusions There may be substantial benefits for the SPPAC program including limited burden on health care professionals, decreased barriers (eg. accessibility, transportation), development of peer social supports, and potential cost savings related to physical inactivity. Before conducting a large and expensive multisite RCT within a small heterogeneous population of manual wheelchair users, a pilot study affords a prudent step to establishing an adequate study protocol and implementation strategies.

Given the rising prevalence of obesity in the United States, innovative methods are needed to increase physical activity (PA) in community settings. Evidence suggests that individuals are more likely to engage in PA if they are given a choice of activities and have support from others (for encouragement, motivation, and accountability). The objective of this study was to describe the use of the online Walk Georgia PA tracking platform according to whether the user was an individual user or group user. Walk Georgia is a free, interactive online tracking platform that enables users to log PA by duration, activity, and perceived difficulty, and then converts these data into points based on metabolic equivalents. Users join individually or in groups and are encouraged to set weekly PA goals. Data were examined for 6,639 users (65.8% were group users) over 28 months. We used independent sample t tests and Mann-Whitney U tests to compare means between individual and group users. Two linear regression models were fitted to identify factors associated with activity logging. Users logged 218,766 activities (15,119,249 minutes of PA spanning 592,714 miles [41,858,446 points]). On average, group users had created accounts more recently than individual users (P < .001); however, group users logged more activities (P < .001). On average, group users logged more minutes of PA (P < .001) and earned more points (P < .001). Being in a group was associated with a larger proportion of weeks in which 150 minutes or more of weekly PA was logged (B = 20.47, P < .001). Use of Walk Georgia was significantly higher among group users than among individual users. To expand use and dissemination of online tracking of PA, programs should target naturally occurring groups (eg, workplaces, schools, faith-based groups).

Physical activity (PA) has the potential to slow the progression of dementia patients' cognitive and physical decline. A better understanding of the factors that facilitate or hamper dementia patients' PA participation will increase the success rate of implementing PA in dementia patients' daily care. We systematically screened the barriers, motivators, and facilitators of PA participation in dementia patients, complementing previous analyses of quantitative correlates of PA in community-dwelling dementia patients. Systematic searches yielded 78 potential studies of which seven met the eligibility criteria including 39 dementia patients and 36 caregivers (33 spouses and three daughters). We identified 35 barriers, 26 motivators, and 21 facilitators related to PA. We reduced these factors to six themes within the social-ecological model. Prominent barriers to PA were physical and mental limitations and difficulties with guidance and organization of PA by caregivers. Motivators included the motivation to maintain physical and mental health and participate in preferred PA options. Facilitators included strategies to avoid health problems, providing support and guidance for PA, and access to convenient and personalized PA options. The emerging picture suggests that dementia patients' PA participation will increase if service providers become familiar with the health benefits of PA, the characteristics of PA programs, methods of delivery, and the concepts of how such programs can be personalized to and synchronized with patients' individual needs.

Increasing physical activity (PA) effectively in those who are inactive is challenging. For those who have subjective memory complaints (SMC) or mild cognitive impairment (MCI) this is a greater challenge necessitating the need for more engaging and innovative approaches. The primary aim of this trial is to determine whether a home-based 6-month PA intervention with individual goal-setting and peer mentors (GM-PA) can significantly increase PA levels in insufficiently active older adults at increased risk of developing Alzheimer's disease (AD). Community living 60-80 year olds with SMC or MCI who do not engage in more than 60 min per week of moderate intensity PA will be recruited from memory clinics and the community via media advertisements to participate in this randomized, single-blind controlled trial. All participants will receive an individually tailored home-based PA program of 150 min of moderate intensity walking/week for 6 months. The intervention group will undertake individual goal-setting and behavioral education workshops with mentor support via telephone (GM-PA). Those randomized to the control group will have standard education workshops and Physical Activity Liaison (PAL) contact via telephone (CO-PA). Increase in PA is the primary outcome, fitness, cognitive, personality, demographic and clinical parameters will be measured and a health economic analysis performed. A saliva sample will be collected for APOE e4 genotyping. All participants will have a goal-setting interview to determine their PA goals. Active volunteers aged 50-85 years will be recruited from the community randomized and trained to provide peer support as mentors (intervention group) or PALS (control group) for the 6-month intervention. Mentors and PALS will have PA, exercise self-efficacy and mentoring self-efficacy measured. Participants in both groups are asked to attend 3 workshops in 6 months. At the first workshop, they will meet their allocated Mentor or PAL who will deliver their respective programs and support via 6 telephone calls during the intervention. If the GM-PA program is successful in increasing the PA levels of the target group it will potentially provide another strategy and community resource that can be translated into practice.

Some religions espouse doctrines that (in)directly impact physical activity (PA) behavior. Yet limited PA interventions have been tailored to religious minorities. Thus, a formative study was conducted to examine the effect of a faith-based pedometer program (Virtual Umra) on psychological correlates of PA behavior and their contribution to school-time changes in PA among Muslim adolescents. Forty-three (27 girls, 16 boys; M(age) = 12.3 +/- 1.0 years) students at 1 Islamic middle school participated. Prebaseline and postprogram enjoyment and motivation were measured using the shortened PA Enjoyment Scale and the Situational Motivation Scale, respectively. Pedometer step counts were measured daily during a 2-week baseline and 8 weeks of Virtual Umra. The Reliable Change Index and Cohen's d were used to analyze individual- and group-level changes in enjoyment and motivation, respectively. Repeated-measures multivariate analysis of variance (RM-MANOVA) was used to analyze program and gender effects over time. Partial correlations examined the relationships between psychological correlates and PA change. One third of the sample expressed greater enjoyment postprogram (p < .001, d = 0.99), while motivation was unaffected (p > .05; range, d = - 0.02 to 0.32). RM-MANOVA revealed that boys increased their steps, whereas girls reduced their step number through the program. Enjoyment increased and extrinsic motivation and amotivation decreased. Partial correlations revealed that enjoyment and more self-determined behavioral regulations were positively associated with non-physical education (PE)-day PA change; only intrinsic motivation was positively associated with PE-day PA change. Virtual Umra was associated with increased enjoyment of PA but needs further modification to more positively impact girls' PA.

The growing evidence of the influence of urban environment on physical activity (PA) underscore the need for novel policy solutions to address the inequality, lack of space, and limited PA resources in rapidly growing Latin American cities. This study aims to better understand the PA policy process by conducting two case studies of Bogotá's Ciclovía and Curitiba's CuritibAtiva. Literature review of peer- and non-peer-reviewed documents and semi-structured interviews with stakeholders was conducted. In the cases of Ciclovía and CuritibAtiva, most policies conducive to program development and sustainability were developed outside the health sector in sports and recreation, urban planning, environment, and transportation. Both programs were developed by governments as initiatives to overcome inequalities and provide quality of life. In both programs, multisectoral policies mainly from recreation and urban planning created a window of opportunity for the development and sustainability of the programs and environments supportive of PA.

Physical activity (PA) programs are a promising strategy to promote positive youth development (PYD). It is not known if published reports provide sufficient information to promote the implementation of effective PYD in indigenous youth. The purpose of this study was to assess the extent to which published literature on PA programs that promote PYD in indigenous youth report on RE-AIM (reach, effectiveness, adoption, implementation, maintenance) indicators. A systematic literature search was conducted to identify articles reporting on PA programs that promote PYD in indigenous youth. The search yielded 8084 articles. A validated 21-item RE-AIM abstraction tool assessing internal and external validity factors was used to extract data from 10 articles meeting eligibility criteria. The most commonly reported dimensions were effectiveness (73 %), adoption (48 %), and maintenance (43 %). Reach (34 %) and implementation (30 %) were less often reported. Published research provides insufficient information to inform real-world implementation of PA programs to promote PYD in indigenous youth.

Introduction There is a need for interventions to address the escalating mental health burden in Sub-Saharan Africa (SSA). Implementation of physical activity (PA) within the rehabilitation of people with mental health problems (PMHP) could reduce the burden and facilitate recovery. The objective of the current review was to explore (1) the role of PA within mental health policies of SSA countries, and (2) the current research evidence for PA to improve mental health in SSA. Methods We screened the Mental Health Atlas and MiNDbank for mental health policies in SSA countries and searched PubMed for relevant studies on PA in PMHP in SSA. Results Sixty-nine percent (=33/48) of SSA countries have a dedicated mental health policy. Two of 22 screened mental health policies included broad physical activity recommendations. There is clear evidence for the role of PA in the prevention and rehabilitation of depression in SSA. Conclusion Despite the existing evidence, PA is largely a neglected rehabilitation modality in the mental health care systems of SSA. Continued education of existing staff, training of specialized professionals and integration of PA for mental health in public health awareness programs are needed to initiate and improve PA programs within the mental health care systems of SSA.

Background: Although school-based behavioral interventions for increasing physical activity (PA) in children and adolescents have been conducted, little evidence suggests that these curriculum-based approaches lead to increases in overall activity outside of program days. The overall goal of the “Active by Choice Today” (ACT) trial is to expand the body of knowledge concerning the factors that influence long-term increases in PA in underserved adolescents (low socioeconmic status, minorities) during their middle school years. Design and setting: An overview of the ACT study design, theoretical framework, process evaluation, and primary hypotheses is presented. The trial involves twenty-four middle schools (1560 6th graders) in South Carolina that are randomly assigned to one of two after-school programs (motivational and life skills intervention, or general health education). Intervention: The intervention integrates constructs from Self-Determination and Social Cognitive Theories to enhance intrinsic motivation and behavioral skills for PA. The intervention targets skill development for PA outside of program days and the after-school program social environment (autonomy, choice, participation, belongingness, fun, enjoyment, support) is designed to positively impact cognitive mediators (self-efficacy, perceived competence), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Main hypotheses/outcomes: It is hypothesized that the 17-week motivational and life skills intervention will lead to greater increases in moderate-to-vigorous PA (based on 7-day accelerometry estimates) at post-intervention as compared to the general health education program. Conclusions: Implications of this innovative school-based trial are discussed. PMID:17716952

Community-based physical activity (PA) programs in Latin America have been recognized because of the use of available environmental resources to offer PA classes. Yet, the evaluation of programs focused on PA classes involving dancing in public spaces is limited. The aim of this study was to assess the physical activity levels, park use, and the contextual characteristics of public parks with and without the Recreovía in Bogotá in Colombia. Al Ritmo de las Comunidades is a natural experiment conducted in nine parks (3 parks implementing new Recreovías, 3 control parks and 3 parks with existing Recreovías) during 2013. We used the System for Observing Play and Recreation in Communities to evaluate park use (gender, age, and physical activity level) and target areas. A total of 4925 people were observed during 702 observation visits to parks. The percentage of women was higher in parks with Recreovía, compared to parks without Recreovía (53% vs. 40% vs. 33%; p < 0.001). Women using parks with Recreovía compared to women in parks without Recreovía were less likely to be sedentary (25% vs. 39%; p < 0.0001) and more likely to engage in moderate-to-vigorous activity (75% vs. 61%; p < 0.0001). Among men, the activity pattern was the opposite.

Community-based physical activity (PA) programs in Latin America have been recognized because of the use of available environmental resources to offer PA classes. Yet, the evaluation of programs focused on PA classes involving dancing in public spaces is limited. The aim of this study was to assess the physical activity levels, park use, and the contextual characteristics of public parks with and without the Recreovía in Bogotá in Colombia. Al Ritmo de las Comunidades is a natural experiment conducted in nine parks (3 parks implementing new Recreovías, 3 control parks and 3 parks with existing Recreovías) during 2013. We used the System for Observing Play and Recreation in Communities to evaluate park use (gender, age, and physical activity level) and target areas. A total of 4925 people were observed during 702 observation visits to parks. The percentage of women was higher in parks with Recreovía, compared to parks without Recreovía (53% vs. 40% vs. 33%; p < 0.001). Women using parks with Recreovía compared to women in parks without Recreovía were less likely to be sedentary (25% vs. 39%; p < 0.0001) and more likely to engage in moderate-to-vigorous activity (75% vs. 61%; p < 0.0001). Among men, the activity pattern was the opposite. The Recreovía is a promising strategy to promote park use and PA, especially among women who are less likely to meet PA recommendations during their leisure time. The provision of a cost-free community program may be an effective approach and a good investment for health.

Abstract Mental health service users (MHSUs) have elevated rates of cardiometabolic disturbance. Improvements occur with physical activity (PA) programs. We report the development and evaluation of three innovative peer-developed and peer-led PA programs: 1) walking; 2) fitness; and 3) yoga. Qualitative evaluation with 33 MHSUs in British Columbia, Canada, occurred. These programs yielded improvements for participants, highlighted by powerful narratives of health improvement, and improved social connections. The feasibility and acceptability of innovative peer-developed and peer-led programs were shown. Analyses revealed concepts related to engagement and change. Relating core categories, we theorize effective engagement of MHSUs requires accessibility on three levels (geographic, cost, and program flexibility) and health behavior change occurs within co-constituent relationships (to self, to peers, and to the wider community). This study highlights the benefits of peer involvement in developing and implementing PA programs and provides a theoretical framework of understanding engagement and behavior change in health programs for MHSUs.

2013-01-01

We examined evidence for friendship influences on children's physical activity (PA) through systematic searches of online databases in May 2012. We identified 106 studies (25 qualitative) published in English since 2000 that analyzed indicators of friendship influences (e.g., communication about PA, friends’ PA, and PA with friends) among persons younger than 19 years. Children's PA was positively associated with encouragement from friends (43 of 55 studies indicating a positive relationship), friends' own PA (30/35), and engagement with friends in PA (9/10). These findings are consistent with friends influencing PA, but most studies did not isolate influence from other factors that could explain similarity. Understanding friendship influences in childhood can facilitate the promotion of lifelong healthy habits. PA with friends should be considered in health promotion programs. PMID:23678914

Effectiveness of a behavioral modification program on physical activity (PA) and sedentary behavior in diabetes patients. Ninety-two patients were randomly assigned to an intervention or control group. The 24-weeks intervention consisted of a face-to-face session, pedometer and seven telephone follow-ups. Mean selection criteria were 35-75 years; 25-35 kg/m(2); ≤ 12% HbA1c, treated for type 2 diabetes; no PA limitations. PA and sedentary behavior were measured by pedometer, accelerometer and questionnaire over the short- (24 weeks) and intermediate- (1 year) term. The intervention group increased their steps/day by 2744, their total PA by 23 min/day (p<0.001) and decreased their sedentary behavior by 23 min/day (p<0.05) post-intervention. After 1 year the intervention group still had an increase of 1872 steps/day, 11 min/day total PA and a decrease of 12 min/day in sedentary behavior (p<0.001). This pedometer-based behavioral modification program with telephone support showed lasting positive effects on steps/day, PA and sedentary behavior. This study tested a convenient way to increase PA among type 2 diabetes patients. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Understanding the dynamic nature of energy balance, and the interrelated and synergistic roles of diet and physical activity (PA) on body weight, will enable nutrition educators to be more effective in implementing obesity prevention education. Although most educators recognize that diet and PA are important for weight management, they may not fully understand their impact on energy flux and how diet alters energy expenditure and energy expenditure alters diet. Many nutrition educators have little training in exercise science; thus, they may not have the knowledge essential to understanding the benefits of PA for health or weight management beyond burning calories. This paper highlights the importance of advancing nutrition educators’ understanding about PA, and its synergistic role with diet, and the value of incorporating a dynamic energy balance approach into obesity-prevention programs. Five key points are highlighted: (1) the concept of dynamic vs. static energy balance; (2) the role of PA in weight management; (3) the role of PA in appetite regulation; (4) the concept of energy flux; and (5) the integration of dynamic energy balance into obesity prevention programs. The rationale for the importance of understanding the physiological relationship between PA and diet for effective obesity prevention programming is also reviewed. PMID:28825615

Inactivity is a prevalent problem in the population affected with multiple sclerosis (MS). Thus, there is a need to develop and test physical activity (PA) interventions that can be widely disseminated. We conducted a formative evaluation as part of a randomized controlled trial of a pamphlet-based PA intervention among 30 women with MS. Pamphlets were customized to sub-sets of participants who shared similar symptoms and barriers to PA. Mixed methods were used to examine the intervention’s influence on self-efficacy, social support, processes of change and stages of change placement, as well as explore participants’ perceived barriers, motivators and strategies for engaging in a PA program. Results indicated that the intervention group significantly improved stages of change placement (F = 16.64, P < 0.01) and social support (F = 4.08, P = 0.05) in comparison to the control group. Fatigue, pain and lack of time were the commonly cited barriers to engage in the PA program; whereas the pamphlets, phone calls and action planning were cited as motivators. Participants used fatigue management strategies, enlisted social support and modified their environment to routinely engage in the PA program. Strategies were identified to improve the PA intervention in future research. PMID:24989822

Physical activity (PA) must be performed regularly to accrue health benefits. However, the majority of manual wheelchair users do not meet PA recommendations. Existing community-based PA programs for manual wheelchair users appear to work, but effect sizes are small and retention is low. Existing PA programs may not fully implement some psychosocial factors that are strongly linked with PA (eg, autonomy). The use of peers and mobile phone technology in the Smartphone Peer PA Counseling (SPPAC) program represents a novel approach to cultivating a PA-supportive environment for manual wheelchair users. The primary objective is to compare change in objective PA between the experimental (SPPAC) and control groups from baseline to postintervention (10 weeks) and follow-up (3 months). Changes in and relationships between subjective PA, wheelchair skills, motivation, self-efficacy (for overcoming barriers to PA for manual wheelchair use), satisfaction of psychological needs for PA, and satisfaction with PA participation will be explored (secondary outcome). Program implementation will be explored (tertiary objective). A total of 38 community-living manual wheelchair users (≥18 years) will be recruited in a randomized controlled trial (RCT). Participants in both the control and experimental groups will receive existing PA guidelines. Participants in the experimental group will also receive the SPPAC program: 14 sessions (~30 min) over a 10-week period delivered by a peer trainer using a mobile phone. PA activities will be based on individuals' preferences and goals. Implementation of important theoretical variables will be enforced through a peer-trainer checklist. Outcomes for objective PA (primary) and subjective PA, wheelchair skills, motivation, self-efficacy, satisfaction of psychological needs, and satisfaction with participation will be collected at three time points (baseline, postintervention, follow-up). Multiple imputations will be used to treat missing data. A mixed-model ANCOVA will be conducted, controlling for covariates (primary and secondary objectives). The strength and direction of the relationships between the primary and secondary outcomes will be explored (secondary objective). Descriptive and content analysis will be used to appraise program implementation (tertiary objective). Funding has been obtained from the Craig Neilsen Foundation and the Canadian Disability Participation Project, with additional funds being sought from the Canadian Institute for Health Research and Fonds de Recherche du Québec-Santé. Pilot evaluation of intervention implementation is currently underway, with enrollment anticipated to begin early 2018. There may be substantial benefits for the SPPAC program including limited burden on health care professionals, decreased barriers (eg. accessibility, transportation), development of peer social supports, and potential cost savings related to physical inactivity. Before conducting a large and expensive multisite RCT within a small heterogeneous population of manual wheelchair users, a pilot study affords a prudent step to establishing an adequate study protocol and implementation strategies.

This study aimed to examine the effectiveness of a physical activity (PA) program on weight control, physical fitness, occupational stress, job satisfaction and quality of life of overweight and sedentary employees in high-tech industries. Participants in the intervention group (n = 37) were instructed to carry out a PA program at moderate intensity for 60 min/session, 3 sessions/week for 12 weeks. Those in the control group (n = 38) received no PA program and were asked to continue their routine lifestyle. Evaluations were performed at baseline and at the end of the intervention. Results of structured questionnaires and blood biochemistry tests and evaluations of physical fitness were analyzed. The PA program effectively reduced the number of risk factors for metabolic syndrome and body fat percentage, and improved physical fitness such as flexibility, muscular strength and endurance and cardiorespiratory endurance. The intervention also significantly decreased levels of serum triglyceride, total cholesterol and low-density lipoprotein cholesterol. Significant positive effects on work control, interpersonal relationships at work, global job satisfaction and quality of life were also demonstrated. This study showed that a PA program can be helpful in improving physical, physiological and psychological outcomes for overweight and sedentary employees in high-tech industries.

Physical activity (PA) public health programming has been widely used in Mexico; however, few studies have documented individual and organizational factors that might be used to evaluate their public health impact. The RE-AIM framework is an evaluation tool that examines individual and organizational factors of public health programs. The purpose of this study was to use the RE-AIM framework to determine the degree to which PA programs in Mexico reported individual and organizational factors and to investigate whether reporting differed by the program's funding source. Public health programs promoting PA were systematically identified during 2008-2013 and had to have an active program website. Initial searches produced 23 possible programs with 12 meeting inclusion criteria. A coding sheet was developed to capture behavioral, outcome and RE-AIM indicators from program websites. In addition to targeting PA, five (42%) programs also targeted dietary habits and the most commonly reported outcome was change in body composition (58%). Programs reported an average of 11.1 (±3.9) RE-AIM indicator items (out of 27 total). On average, 45% reported reach indicators, 34% reported efficacy/effectiveness indicators, 60% reported adoption indicators, 40% reported implementation indicators, and 35% reported maintenance indicators. The proportion of RE-AIM indicators reported did not differ significantly for programs that were government supported (M = 10, SD = 3.1) and programs that were partially or wholly privately or corporately supported (M = 12.0, SD = 4.4). While reach and adoption of these programs were most commonly reported, there is a need for stronger evaluation of behavioral and health outcomes before the public health impact of these programs can be established.

To examine the workplace food and physical activity (PA) environments and wellness culture reported by employed United States adults, overall and by employer size. Cross-sectional study using web-based survey on wellness policies and environmental supports for healthy eating and PA. Worksites in the United States. A total of 2101 adults employed outside the home. Survey items were based on the Centers for Disease Control and Prevention Worksite Health ScoreCard and Checklist of Health Promotion Environments and included the availability and promotion of healthy food items, nutrition education, promotion of breast-feeding, availability of PA amenities and programs, facility discounts, time for PA, stairwell signage, health promotion programs, and health risk assessments. Descriptive statistics were used to examine the prevalence of worksite environmental and facility supports by employer size (<100 or ≥100 employees). Chi-square tests were used to examine the differences by employer size. Among employed respondents with workplace food or drink vending machines, approximately 35% indicated the availability of healthy items. Regarding PA, 30.9% of respondents reported that their employer provided opportunities to be physically active and 17.6% reported worksite exercise facilities. Wellness programs were reported by 53.2% working for large employers, compared to 18.1% for smaller employers. Employee reports suggested that workplace supports for healthy eating, PA, and wellness were limited and were less common among smaller employers.

Impact of a supervised exercise program supporting autonomy on the adoption of an active lifestyle among obese adolescents: a Self-Determination Theory perspective.

Regular physical activity (PA) practice represents a key component of obesity treatment. Drawing upon Self-Determination Theory, the purpose of this study was twofold. The first aim was to evaluate among obese adolescents the impact of a supervised exercise program supporting autonomy on their motivation to practice PA at the end of the intervention. The second aim was to evaluate the impact of the program on their level of PA one month after the end of the intervention. Eighteen obese adolescents (mean age=14.3 years, mean BMI=33.47 kg/m²) were recruited to participate in an 11-week residential obesity treatment program. They received a 45-minute supervised exercise session each week. Motivational regulations were assessed at baseline and at the end of the intervention (via the Exercise Motivation Scale). PA practice was assessed at baseline and one month after the end of the intervention (via the 7-day PA recall interview). The analyses revealed that adolescents' levels of autonomy increased, that their levels of intrinsic motivation tended to increase, and that their level of external regulation tended to decrease. In addition, the participants increased their habitual PA practice one month after the end of the intervention in comparison to baseline. This study highlights that supporting autonomy during supervised exercise sessions appears as an effective strategy to promote PA among obese adolescents because it fosters internalization of the behavior.

To evaluate the current level of physical activity (PA) training provided to Australian medical students. Individual interviews were completed via phone interview or online survey from June-October 2015. Program leaders from Australian medical schools, who were knowledgeable about their curriculum content, were invited to participate in the study. The number of programs, hours of PA training instruction, institutional attitude towards offering PA, barriers experienced, and content areas in which PA training was offered, were explored. Seventeen of the 19 (89%) Australian medical schools participated in the study. Among the responding schools, 15 (88.2%) reported providing specific PA training to medical students. Thirteen of these 15 schools (86.7%) taught the national aerobic guidelines while only seven (46.7%) taught the national strength training recommendations. Four, five, and six year programs reported providing an average of 6.6, 5.0, and 12.3h of PA training, respectively, across their entire curriculum. Only 42.9% of the schools that had PA training reported that it was sufficient for their medical students. Nearly half (41.2%) of the respondents reported no barriers to implementing PA training into their medical curricula. Most Australian medical schools reported including some PA training in their medical curriculum. Key topics, such as the national strength recommendations, however, were not taught by most schools. Given the importance of PA for the prevention and treatment of numerous mental and physical health outcomes, it is unlikely that the attention it currently receives adequately prepares medical students to treat patients.

Lifestyle modification programs (LMPs) can provide individuals with behavioral skills to sustain long-term changes to their physical activity (PA) levels and dietary habits. Yet, there is much work to be done in the translation of these programs to community settings. This review identified LMPs that focused on changing both PA and dietary behaviors and examined common features and barriers faced in their translation to community settings. A search of multiple online databases was conducted to identify LMPs that included participants over the age of 18 who enrolled in LMPs, offered in community settings, and had the goal of improving both PA and dietary behaviors. Data were extracted on participant demographics, study design characteristics, and study outcome variables including changes in PA, dietary habits, body weight, and clinical outcomes. We identified 27 studies that met inclusion criteria. Despite high levels of retention and adherence to the interventions, varying levels of success were observed in increasing PA levels, improving dietary habits, reducing body weight, and improving clinic outcomes. LMPs addressing issues of PA and dietary habits can be successfully implemented in a community setting. However, inconsistent reporting of key components in the translation of these studies (participant recruitment, utilization of behavioral strategies) may limit their replication and advancement of future programs. Future efforts should better address issues such as identifying barriers to participation and program implementation, utilization of community resources, and evaluating changes across multiple health behaviors.

Abstract Objective Despite the physical and psychological health benefits associated with physical activity (PA) for breast cancer (BC) survivors, up to 70% of female BC survivors are not meeting minimum recommended PA guidelines. The objective of this study was to evaluate acceptability and satisfaction with Project MOVE, an innovative approach to increase PA among BC survivors through the combination of microgrants and financial incentives. Methods A mixed‐methods design was used. Participants were BC survivors and support individuals with a mean age of 58.5 years. At 6‐month follow‐up, participants completed a program evaluation questionnaire (n = 72) and participated in focus groups (n = 52) to explore their experience with Project MOVE. Results Participants reported that they were satisfied with Project MOVE (86.6%) and that the program was appropriate for BC survivors (96.3%). Four main themes emerged from focus groups: (1) acceptability and satisfaction of Project MOVE, detailing the value of the model in developing tailored group‐base PA programs; (2) the importance of Project MOVE leaders, highlighting the value of a leader that was organized and a good communicator; (3) breaking down barriers with Project MOVE, describing how the program helped to address common BC related barriers; and (4) motivation to MOVE, outlining how the microgrants enabled survivors to be active, while the financial incentive motivated them to increase and maintain their PA. Conclusion The findings provide support for the acceptability of Project MOVE as a strategy for increasing PA among BC survivors. PMID:29409128

To evaluate the impact of a primary school-based physical activity (PA) integration program delivered by teachers on objectively measured PA and key educational outcomes. Ten classes from 8 Australian public schools were randomly allocated to treatment conditions. Teachers from the intervention group were taught to embed movement-based learning in their students' (n = 142) daily mathematics program in 3 lessons per week for 6 weeks. The control group (n = 98) continued its regular mathematics program. The primary outcome was accelerometer-determined PA across the school day. Linear mixed models were used to analyze treatment effects. Significant intervention effects were found for PA across the school day (adjusted mean difference 103 counts per minute [CPM], 95% confidence interval [CI], 36.5-169.7, P = .008). Intervention effects were also found for PA (168 CPM, 95% CI, 90.1-247.4, P = .008) and moderate-to-vigorous PA (2.6%, 95% CI, 0.9-4.4, P = .009) in mathematics lessons, sedentary time across the school day (-3.5%, 95% CI, -7.0 to -0.13, P = .044) and during mathematics (-8.2%, CI, -13.0 to -2.0, P = .010) and on-task behavior (13.8%, 95% CI, 4.0-23.6, P = .011)-but not for mathematics performance or attitude. Integrating movement across the primary mathematics syllabus is feasible and efficacious.

Individual, social, and community barriers to physical activity (PA) experienced by children with autism spectrum disorder (ASD) make PA participation more difficult and may contribute to increased screen time. We compared the prevalence of parent-reported barriers to PA among 58 typically developing (TD) children and 53 children with an ASD, 3 to 11 years, and assessed the association between barriers and PA participation and screen time among children with ASD. Parents of children with ASD reported significantly more barriers than parents of TD children. Based on parent-report, 60% of children with ASD required too much supervision compared with no TD children (P < .001). Parents of children with ASD were more likely to report that adults lack skills needed to include their child (58%), that their child has few friends (45%), and that other children exclude their child (23%). The number of parent-reported barriers to PA was inversely correlated with the hours spent in PA per year (r = -0.27, P = .05) and positively related to total screen time (r = .32, P < .03). These findings underscore the need for community-based PA programs designed to meet the special requirements of this population and policies that compel schools and other government-supported organizations for inclusion and/or targeted programming.

As the US population ages, there is an increasing need for evidence based, peer-led physical activity programs, particularly in ethnically diverse, low income senior centers where access is limited. The Peer Empowerment Program 4 Physical Activity' (PEP4PA) is a hybrid Type II implementation-effectiveness trial that is a peer-led physical activity (PA) intervention based on the ecological model of behavior change. The initial phase is a cluster randomized control trial randomized to either a peer-led PA intervention or usual center programming. After 18 months, the intervention sites are further randomized to continued support or no support for another 6 months. This study will be conducted at twelve senior centers in San Diego County in low income, diverse communities. In the intervention sites, 24 peer health coaches and 408 adults, aged 50 years and older, are invited to participate. Peer health coaches receive training and support and utilize a tablet computer for delivery and tracking. There are several levels of intervention. Individual components include pedometers, step goals, counseling, and feedback charts. Interpersonal components include group walks, group sharing and health tips, and monthly celebrations. Community components include review of PA resources, walkability audit, sustainability plan, and streetscape improvements. The primary outcome of interest is intensity and location of PA minutes per day, measured every 6 months by wrist and hip accelerometers and GPS devices. Secondary outcomes include blood pressure, physical, cognitive, and emotional functioning. Implementation measures include appropriateness & acceptability (perceived and actual fit), adoption & penetration (reach), fidelity (quantity & quality of intervention delivered), acceptability (satisfaction), costs, and sustainability. Using a peer led implementation strategy to deliver a multi-level community based PA program can enhance program adoption, implementation, and sustainment. ClinicalTrials.gov, USA ( NCT02405325 ).

The prevalence of non-communicable diseases (NCDs) is increasing worldwide, also among children. Information about primary prevention of NCD's is increasing; however, convincing strategies among children is needed. The present paper describes the design and methods in the Health Oriented Pedagogical Project (HOPP) study. The main objective is to evaluate the effects of a school-based physical activity intervention program on cardio-metabolic risk factors. Secondary objectives include assessment of physical, psychological and academic performance variables. The HOPP study is a 7 years longitudinal large-scale controlled intervention in seven elementary schools (n = 1545) with two control schools (n = 752); all aged 6-11 years at baseline. The school-based physical activity intervention program includes an increase in physical activity (PA) of 225 min/week as an integrated part of theoretical learning, in addition to the curriculum based 90 min/week of ordinary PA. Primary outcomes include cardio-metabolic risk factors measured as PA level, BMI status, waist circumference, muscle mass, percent fat, endurance test performance, total serum cholesterol, high-density lipoprotein (HDL), non-HDL, micro C-reactive protein (mCRP) and long-term blood sugar (HbA1c). In addition, secondary outcomes include anthropometric growth measures, physical fitness, quality of life (QoL), mental health, executive functions, diet and academic performance. HOPP will provide evidence of effects on cardio-metabolic risk factors after a long-term PA intervention program in elementary schoolchildren. School-based PA intervention programs may be an effective arena for health promotion and disease prevention. The study is registered in Clinical trials (ClinicalTrials.gov Identifier: NCT02495714 ) as of June 20 th - 2015, retrospectively registered. The collection of baseline values was initiated in mid-January 2015.

The Recreovia program provides free physical activity (PA) classes in public spaces in Bogota, Colombia. The purpose of this study was to assess the effectiveness of the Recreovia program in increasing PA among users of nine parks in Bogota. This study was a natural experiment conducted between 2013 and 2015 in Bogota. Community members and park users living nearby three groups of parks were compared: Group 1 were parks implementing new Recreovias (n=3), Group 2 were control parks (n=3) without Recreovias, and Group 3 were parks with existing Recreovías. Individuals in the "intervention" group were exposed to newly implemented Recreovia programs in parks near their homes. Measurements were collected at baseline and 6-8months after the intervention started. A total of 1533 participants were enrolled in the study: 501 for the existing Recreovias (included in a cross-sectional assessment) and 1032 participants (from the new Recreovias and control parks) included in the cross-sectional and pre-post study. Most participants were low income females. Twenty-three percent of the intervention group started participating in the program. Users of existing Recreovias were significantly more active and less likely to be overweight/obese compared to new Recreovia users at baseline. No changes on PA were found when comparing the intervention and control groups. Recreovias may have potential for increasing PA at the population level in urban areas given their rapid scalability, the higher levels of PA observed among program users, and its potential to reach women, low-income, less educated populations, and the overweight and obese.

To evaluate the effectiveness of a 9 months of supervised Physical Activity (PA) Program with sociocultural activities, on self-esteem and its association on the control of chronic diseases in adult primary care users. Multicenter, randomized, controlled community intervention. 4 Primary care centers in Reus-Tarragona, Spain. 364 subjects, randomized to the Control Group (CG=104) and Intervention Group (IG=260). Supervised walking program of 120min/week with sociocultural activities once a month. At baseline and at post-intervention we assessed: PA (IPAQ-S), self-esteem (Rosenberg scale) and cardiovascular indicators: smoking, systolic (SBP) and diastolic (DBP) blood pressure, serum LDL and HDL cholesterol, and serum glucose. Sociodemographic characteristics and diagnostic of chronic diseases are recorded. The Program increased the PA in the IG (P=.001), while it decreased in the CG (P=.002), and also the self-esteem in the group of participants (1.28 points, P=.006) and in the groups with diagnoses of hypertension (1.60 points, P=.005), dyslipidemia (1.62 points, P=.012), excess weight (1.24 points, P=.011) or anxiety/depression (1.53 points, P=.045), assessed by multivariate statistical models. The increase in self-esteem during the intervention decreased SBP -0.5mmHg (P=.030) in the hypertension group, regardless of baseline SBP and the effect of the intervention. The PA program increased the PA and self-esteem in adult primary care users. The increase of self-esteem improved the control of SBP in hypertensive patients. Copyright © 2018 The Authors.

This study aims to test the efficacy of text messaging cues (SMS) to promote physical activity (PA) habit formation in the workplace. Employees (N = 49; 28 females and 21 males, Mage = 47.5 ± 8.29 years) were randomized into two parallel groups: a PA group enrolled in a 28-week supervised PA program and a PA+SMS group enrolled in the same PA program with text messaging cues received before their PA sessions. The exercise habit was assessed every week from self-reports on an online application. PA maintenance and several physical fitness measures were also assessed prior to and after the intervention to evaluate its general impact. Mixed model analysis of the 603 observations indicated a small but significant effect of the SMS cues on the speed at which participants engaged in PA behaviors, as the significant interaction effect revealed that the slope of the exercise habit over time was slightly steeper in the PA+SMS group (B = 0.0462, P = 0.0001) than in the PA group (B = 0.0216, P = 0.01). SMS delivery had a marginal effect on the maintenance of PA behaviors 1 year after the intervention. The results suggest that text messaging can help to form PA habits at the workplace and might facilitate long-term maintenance of PA behaviors. © 2016 John Wiley & Sons A/S.

Current literature supports the link between physical activity (PA) or fitness and a child's ability to achieve academically; however, little structured activity time is incorporated into elementary school classrooms. This paper explores the impact of a classroom-based PA program, TAKE 10!, and health-academic integration through existing state and federal policy and programming. Evidence from journal articles, published abstracts, and reports were examined to summarize the impact of TAKE 10! on student health and other outcomes. This paper reviews 10 years of TAKE 10! studies and makes recommendations for future research. Teachers are willing and able to implement classroom-based PA integrated with grade-specific lessons (4.2 days/wk). Children participating in the TAKE 10! program experience higher PA levels (13%>), reduced time-off-task (20.5%), and improved reading, math, spelling and composite scores (p<0.01). Furthermore, students achieved moderate energy expenditure levels (6.16 to 6.42 METs) and studies suggest that BMI may be positively impacted (decreases in BMI z score over 2 years [P<0.01]). TAKE 10! demonstrates that integrating movement with academics in elementary school classrooms is feasible, helps students focus on learning, and enables them to realize improved PA levels while also helping schools achieve wellness policies.

Mounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

The effects of increases in physical activity (PA) on early literacy skills in preschool children are not known. Fifty-four African-American preschool children from a low socioeconomic urban Head Start participated over 8 months. A 2-group, quasi-experimental design was used with one preschool site participating in the PA intervention and a second site participating as the control site. The PA program was designed to promote 300 minutes/week of moderate to vigorous PA academic lessons. Academic achievement related to early literacy and phonological awareness in the areas of rhyming and alliteration were assessed at baseline, 4 and 8 months. Over 8 months, rhyming significantly (p < .01) improved in the PA group (173 ± 12%) compared with the controls (28 ± 8%) resulting in between group differences at 8 months (p < .01). Alliteration significantly (p < .01) improved in the PA group (52 ± 16%) compared with controls (13 ± 5%), resulting in between group differences at 8 months (p < .01). As minutes of exposure to moderate to vigorous PA increased, the change in picture naming (R(2) = .35, p < .05), alliteration (R(2) = .38, p < .05), and rhyming (R(2) = .42, p < .05), increased. A teacher-directed PA program is effective at increasing PA and improving early literacy. © 2016, American School Health Association.

To investigate the efficacy of using "Instagram application" with a "home-exercise program" as a motivational stimulus in improving physical activity (PA) adherence levels among female college students. Fifty-eight female undergraduate students with the mean age 20.3 ± 0.96 years participated. Participants were divided into two groups: intervention and the control group; both the groups received an exercise program and the intervention group was additionally motivated by "Instagram." Adherence to PA was measured by using an adherence sheet. The Exercise Motivation Inventory (EMI-2) was used to assess the motivational factors. The most frequent motivational factors were extrinsic as assessed using the EMI-2. "Positive health" was the most frequent factor mentioned of the two types with 47% of the sample. The intervention group adhered with 17% more to the activity program compared to the control group. Moreover, 72% of the participants in the intervention and control groups found the activity program flexible enough to be performed at home; they agreed about its effectiveness on adherence (53%). The use of Instagram with the home exercise program as a motivational modality could be attractive and effective to reinforce adherence and maintain an appropriate PA level.

Physical inactivity is a determinant of clinical disorders and psychological problems in patients with chronic kidney disease patients. In two satellite clinics, a program of physical activity (PA) was offered to 86 patients undergoing hemodialysis. Of those, 49 patients entered the PA program spontaneously and 37 remained inactive. After six months, a satisfaction self-reported questionnaire and the Modified Mini-Mental State (3MS) Examination for assessment of cognitive function were applied. Cognition was compared between inactive patients and those participating in the PA program for at least three months. Regardless of age and duration of dialysis, patients showed a cognitive deficit greater than expected. In the general group, better cognitive function was observed in active patients as compared to the inactive ones (p < 0.05). When separated by age groups, active patients over the age of 60 years had better results than the inactive ones (p < 0.05). We concluded that patients with better cognitive responses are more physically active and/or physical activity contributes to better cognitive function.

Young adults with mobility disability (MD) are less likely to engage in regular physical activity (PA) compared with their able-bodied peers and inactive adults with a MD are more likely to report one or more chronic diseases compared to those who are physically active. Despite the vast amount of research published in the field of PA interventions over the past decades, little attention has been focused on interventions aiming to increase PA among individuals with MD. Thus, we propose to compare the effects of an eHealth program compared to a usual care supervised health program on levels of PA and other health behaviors. The current intervention will use a randomized controlled trial (RCT) design with two treatment groups (an eHealth program and a usual care supervised health program) in young adults with newly acquired MD. In total, 110 young adults (aged 18-40 years) with a MD, acquired within the past 3 years, will be recruited to participate in a 12-week intervention. The primary study outcome is accelerometer-measured time spent in moderate to vigorous PA. Secondary outcomes includes health-related quality of life, depression, stress, fitness, body composition, diet, musculoskeletal pain, motivation to exercise and work ability. There is a lack of RCTs investigating effective ways to increase levels of PA in young adults with MD. Increased levels of PA among this physically inactive population have the potential to substantially improve health-related outcomes, possibly more so than in the general population. The trial will put strong emphasis on optimizing exercise adherence and investigating feasibility in the two treatment programs. The Ethical Review Board (EPN) at Karolinska Institutet has approved the study (2017/1206-31/1). International Standard Randomised Controlled Trial Number (ISRCTN), reference number ISRCTN22387524 .

Inactivity is a prevalent problem in the population affected with multiple sclerosis (MS). Thus, there is a need to develop and test physical activity (PA) interventions that can be widely disseminated. We conducted a formative evaluation as part of a randomized controlled trial of a pamphlet-based PA intervention among 30 women with MS. Pamphlets were customized to sub-sets of participants who shared similar symptoms and barriers to PA. Mixed methods were used to examine the intervention's influence on self-efficacy, social support, processes of change and stages of change placement, as well as explore participants' perceived barriers, motivators and strategies for engaging in a PA program. Results indicated that the intervention group significantly improved stages of change placement (F = 16.64, P < 0.01) and social support (F = 4.08, P = 0.05) in comparison to the control group. Fatigue, pain and lack of time were the commonly cited barriers to engage in the PA program; whereas the pamphlets, phone calls and action planning were cited as motivators. Participants used fatigue management strategies, enlisted social support and modified their environment to routinely engage in the PA program. Strategies were identified to improve the PA intervention in future research. © The Author 2014. Published by Oxford University Press. All rights reserved.

The effect of intensity and duration of physical activity (PA) on weight loss has been well described. However, the effect of the frequency of weekly PA on weight loss is still unknown. The purpose of this study was to evaluate the effect of the frequency of weekly PA sessions while maintaining the same total activity time on weight loss during a 24-wk weight loss program. Overweight and obese women [n = 75; body mass index (BMI; in kg/m 2 ): 27-37; age: 18-40 y] who had a normally sedentary lifestyle were randomly allocated to 1 of 2 intervention groups: a high-frequency physical activity (HF) or a low-frequency physical activity (LF) group. The HF group included 50 min/d PA, 6 d/wk (300 min/wk). The LF group included 100 min/d PA, 3 d/wk (300 min/wk). Both groups were advised to follow the same dietary weight loss program. Both groups showed a significant decrease in anthropometric measurements and significant improvements in cardiometabolic disease risk characteristics over the 24 wk of the study. Compared with the HF group, the LF group had a greater decrease in weight (mean ± SD; LF: 9.58 ± 3.77 kg; HF: 7.78 ± 2.68 kg; P = 0.028), BMI (LF: 3.62 ± 1.56; HF: 2.97 ± 1.02; P = 0.029) and waist circumference (LF: 9.36 ± 4.02 cm; HF: 7.86 ± 2.41 cm; P = 0.031). However, there were no significant differences in carbohydrate metabolism characteristics or lipid profile after the 24 wk of intervention. Weekly PA undertaken over fewer sessions of longer duration during the week could be more effective for weight loss than when undertaken as more frequent shorter sessions in overweight and obese women on a weight loss program. This may be helpful for those who are neither willing nor able to schedule time for PA almost every day to achieve weight loss.

Exercise is considered an important component of a healthy lifestyle but there remains controversy on effects of exercise on non-exercise physical activity (PA). The present study examined the prospective association of aerobic and resistance exercise with total daily energy expenditure and PA in previously sedentary, young men. Nine men (27.0 ± 3.3 years) completed two 16-week exercise programs (3 exercise sessions per week) of aerobic and resistance exercise separated by a minimum of 6 weeks in random order. Energy expenditure and PA were measured with the SenseWear Mini Armband prior to each intervention as well as during week 1, week 8 and week 16 of the aerobic and resistance exercise program. Body composition was measured via dual x-ray absorptiometry. Body composition did not change in response to either exercise intervention. Total daily energy expenditure on exercise days increased by 443 ± 126 kcal/d and 239 ± 152 kcal/d for aerobic and resistance exercise, respectively (p < 0.01). Non-exercise moderate-to-vigorous PA, however, decreased on aerobic exercise days (-148 ± 161 kcal/d; p = 0.03). There was no change in total daily energy expenditure and PA on non-exercise days with aerobic exercise while resistance exercise was associated with an increase in moderate-to-vigorous PA during non-exercise days (216 ± 178 kcal/d, p = 0.01). Results of the present study suggest a compensatory reduction in PA in response to aerobic exercise. Resistance exercise, on the other hand, appears to facilitate non-exercise PA, particularly on non-exercise days, which may lead to more sustainable adaptations in response to an exercise program.

Barriers and enabling factors for work-site physical activity programs: a qualitative examination.

Work sites offer a productive setting for physical activity (PA) promoting interventions. Still, PA participation remains low. Thus, the purpose of this study was to examine the reasoning behind commonly reported barriers and enabling factors to participation in PA programs in a work-site setting. Employees from a large city government were recruited to participate in focus groups, stratified by white- and blue-collar occupations. Responses from open-ended questions about factors influencing participation in PA programs were audio recorded and transcribed verbatim. Resulting data were analyzed with open and axial coding. The sample consisted of 60 employees composing 9 focus groups. Although time was the most common barrier between both groups, white-collars workers responded that scheduling and work conflicts were the most common barrier concerning time. Blue-collar workers indicated shift work as their most common barrier. In addition, health was a significant enabling factor for both occupational categories. White-collar workers were much more concerned with appearances and were more highly motivated by weight loss and the hopefulness of quick results than were blue-collar workers. These findings are important in the understanding of PA as it relates to the reasoning behind participation in work-site programs in regard to occupational status.

Background Less than 45% of U.S. children meet the 60 min.d-1 physical activity (PA) guideline. Structured after-school PA programing is one approach to help increase activity levels. This study aimed to evaluate the feasibility and short-term impact of a supervised after-school PA and nutrition education program on activity levels. Methods Forty-two 3rd-5th graders from an inner-city school in Boston, MA were randomly assigned to a 10-wk after-school program of either: 1) weekly nutrition education, or 2) weekly nutrition education plus supervised PA 3 d.wk-1 at a community-based center. At baseline and follow-up, PA was measured using accelerometry and fitness (VO2max) was estimated using the PACER 15-m shuttle run. Additional measures obtained were non-fasting finger stick total cholesterol (TC) and glucose levels, waist circumference (WC), body mass index (BMI), percent body fat (%BF), and blood pressure (BP). Values are presented as mean±SE, unless noted otherwise. Results Thirty-six participants completed the study (mean±SD; age 9.7±0.9 years). Participants attended >80% of the sessions. After adjusting for accelerometer wear time and other design factors, light and moderate-to-vigorous PA (MVPA) increased in the nutrition+PA group (+21.5±14.5 and +8.6±8.0 min.d-1, respectively) and decreased in the nutrition only group (-35.2±16.3 and -16.0±9.0 min.d-1, respectively); mean difference between groups of 56.8±21.7 min.d-1 (light PA, p = 0.01) and 24.5±12.0 min.d-1 (MVPA, p = 0.04). Time spent in sedentary behaviors declined in the nutrition+PA group (-14.8±20.7 min.d-1) and increased in the nutrition only group (+55.4±23.2 min.d-1); mean difference between groups of -70.2±30.9 min.d-1 (p = 0.02). Neither group showed changes in TC, BP, WC, %BF, BMI percentile, or fitness (p>0.05). Conclusions The supervised afterschool community-based nutrition and PA program was well accepted and had high attendance. The changes in light PA and MVPA has potential to promote weight maintenance in inner-city elementary school children, however longer term studies with larger samples are needed.

Regular physical activity (PA) is associated with a reduced risk for chronic health conditions and improved health-related quality of life (HRQoL). Efforts to increase PA have included workplace health promotion. Currently, little is known about the effect of these programs on overall HRQoL. To evaluate whether participation in a pedometer-based PA program in the workplace was associated with changes in HRQoL. 487 voluntary employees enrolled in a health program completed the SF-12 Health Survey at baseline and 4 months. Change in Physical and Mental component summary scores (PCS; MCS) was assessed with multivariable regression analysis, adjusting for covariates. Participation in the program was associated with an increase of 1.5 MCS units (95% CI: 0.76, -2.09). Greater improvements in MCS were observed in those reporting an increased level of PA during the program [1.9 (CI: 0.78, 2.92) versus 0.9 (CI: -0.12, 2.03)] and a lower baseline MCS score [6.3 (CI: 4.80, 7.62) versus -1.5 (CI: -2.21, -0.80)]. No change in PCS was observed. Participation in this workplace PA program was associated with improvements in the mental component of HRQoL. We recommend the use of a broad perspective of health be used in both the implementation and evaluation of workplace PA programs.

In Western countries, individuals from multi-ethnic disadvantaged populations are less physically active than the Western population as a whole. This lack of physical activity (PA) may be one of the factors explaining disparities in health. Exercise on Prescription" (EoP), is an exercise program to which persons are referred by primary care. It has been developed to suit the needs of physically inactive women from diverse ethnic backgrounds living in deprived neighborhoods in the Netherlands. The effectiveness of this program has however, not yet been proven. A total of 514 women from diverse ethnic backgrounds were included in this study (192 EoP, 322 control group). Women in the EoP group participated in 18 sessions of supervised PA. The control group received care as usual. At baseline, 6 and 12 months the women attended an interview and a physical examination. Outcome measures were PA, BMI, weight circumference, fat percentage, oxygen uptake, mental well-being, subjective health and use of care. Of the participants 59% had a low educational level and 90% of the women were overweight or obese. Compliance was high, only 14% dropped out during the course of the program. Total PA did not change, PA during leisure time increased at 6 and at 12 months and PA during household activities increased at 12 months (PEoPvsControl < 0.05). EoP had no significant effect on the other outcome variables. EoP was successful in recruiting its target population and compliance was high. The effect of EoP on PA, health and mental well-being was limited. In this format EoP does not seem to be effective for increasing PA and the health status of non-Western migrant women.

From a public health perspective, identifying factors related to attaining the physical activity (PA) recommendations is important in order to identify subgroups for intervention programs. The aim of this study is to identify the socio-demographic correlates of attaining the recommended levels of PA in the older European population. Using data from the European Social Survey round 6, PA and socio-demographic characteristics were collected from 10,148 participants (4556 men, 5592 women), aged 65 years and over, from 28 countries in 2012. PA was accessed using the question "On how many of the last seven days did you walk quickly, do sports, or other PA for 30 min or longer?" and meeting PA guidelines was assessed using World Health Organization criteria. Overall, 59.7% of the participants attained the PA-recommended levels. The likelihood of attaining PA recommendations was higher among older people with higher education levels ( p  < 0.05; p  < 0.01; p  < 0.001). Men who lived in a town or small city ( p  < 0.05) and lived in a rural area ( p  < 0.001) were more likely to attain the PA recommendations. Women who lived with a partner were more likely to attain the PA recommendations ( p  < 0.001). Promotion of PA is critical to health among older people; therefore, intervention programs must consider these socio-demographic factors when planning an increase in PA.

Background Policies call on afterschool programs to improve the physical activity and nutrition habits of youth attending. No tool exists to assess the extent to which the afterschool program environment meets physical activity and nutrition policies. Purpose To describe the development of the Healthy Afterschool Activity and Nutrition Documentation (HAAND) instrument, which consists of two subscales: Healthy Afterschool Program Index for Physical Activity (HAPI-PA) and the HAPI-Nutrition (HAPI-N). Methods Thirty-nine afterschool programs took part in the HAAND evaluation during fall/spring 2010–2011. Inter-rater reliability data were collected at 20 afterschool programs during a single site visit via direct observation, personal interview and written document review. Validity of the HAPI-PA was established by comparing HAPI-PA scores to pedometer steps collected in a subsample of 934 children attending 25 of the afterschool programs. Validity of the HAPI-N scores was compared against the mean number of times/week that fruits/vegetables (FV) and whole grains were served in the program. Results Data were analyzed in June/July 2011. Inter-rater percent agreement was 85%–100% across all items. Increased pedometer steps were associated with the presence of a written policy related to physical activity, amount/quality of staff training, use of a physical activity curriculum, and offering activities that appeal to both genders. Higher servings of FV and whole grains per week were associated with the presence of a written policy regarding the nutritional quality of snacks. Conclusions The HAAND instrument is a reliable and valid measurement tool that can be used to assess the physical activity and nutritional environment of afterschool programs. PMID:22898119

The aim of this study was to determine the effects of nutritional education and vigorous physical activity on health-related parameters. The sample group consisted of 134 children from 5 rurally located schools. Participants were divided between 5 different experimental groups: control group (CG), physical activity group (PA), nutritional education group (NE), combined intervention group (PA+NE), and a combined intervention group with additional substitution of normally used oil for extra virgin olive oil (EVOO; PA+NE+EVOO). The intervention consisted of 60 minute sessions of physical activity held twice a week as well as nutritional education sessions held over 6 months. Students in the groups receiving physical activity reduced their fat percentage and increased their muscle mass post intervention. At posttest the lipid profile improved in all intervention groups. The proportion of macronutrients and dietary cholesterol improved in the groups receiving nutritional education. The posttest comparison showed significantly lower fat percentage, sum of skinfolds and waist circumference in NE relative to CG and PA relative to CG. Diastolic blood pressure and glycaemia were significantly lower in PA+NE+EVOO relative to CG. A school-based program consisting of nutritional education or nutritional education plus a physical activity program showed a positive effect on health-related parameters in children.

Understanding the impacts of the built environment on physical activity (PA) is essential to promoting children's PA. The purpose of this study was to investigate the effects of schoolyard renovations and a PA recess curriculum alone and in combination on children's PA. This was a 2 (learning landscape [LL] vs. non-LL) × 2 (curriculum intervention vs. no curriculum intervention) factorial design with random assignment to the curriculum intervention, and six elementary schools per condition. PA outcomes were assessed preprogram, mid-program, immediate postprogram, and one year postprogram. No meaningful intervention effects were found. Lack of an effect may be due to the brief dose of recess, the curriculum not being integrated within the schoolyard, the LL implementation occurring prior to the study, or the already high levels of PA. Potential avenues to promote PA include making recess longer, integrating recess into the school curricula, and developing recess PA curricula integrating schoolyards.

Physical and psychological symptoms limit physical activity for people with arthritis. This study examined if self-efficacy mediated a relationship between symptom and physical activity (PA) frequency change. This was a secondary analysis of older adults with arthritis and joint pain in a trial of a lifestyle PA program (n = 339). Measures were depressive symptoms, pain, fatigue, arthritis self-efficacy, PA self-efficacy, and PA frequency. A panel model was used to analyze relationships at baseline and changes at 20 weeks. The mean age was 68.8 years. At baseline, depression and fatigue were associated with arthritis self-efficacy (β = -.34 and -.24) and, in turn, PA self-efficacy (β = .63); PA self-efficacy was associated with PA (β = .15). Pain and depression changes were associated with arthritis self-efficacy change (β = -.20 and -.21) and, in turn, PA self-efficacy (β = .32) change; PA self-efficacy change was associated with PA change (β = .36). Change in symptom severity affected change in PA frequency. These relationships appeared to operate through self-efficacy. Over time, pain appeared to have a stronger relationship than fatigue with self-efficacy and PA. These findings support strategies to help people with arthritis strengthen their confidence for symptom coping and PA participation.

Objectives The purpose of this study was to examine whether mothers’ musical background has an effect on their own and their children’s sedentary behavior (SB) and physical activity (PA). The aim was also to assess children’s and their mothers’ exercise adherence when using movement-to-music video program. Design Sub-group analysis of an intervention group in a randomized controlled trial (ISRCTN33885819). Method Seventy-one mother-child-pairs were divided into two categories based on mothers’ musical background. Each pair performed 8 weeks exercise intervention using movement-to-music video program. SB and PA were assessed objectively by accelerometer, and exercise activity, fidelity, and enjoyment were assessed via exercise diaries and questionnaires. Logistic regression model was used to analyze associations in the main outcomes between the groups. Results Those children whose mothers had musical background (MB) had greater probability to increase their light PA during the intervention, but not moderate-to-vigorous PA compared to those children whose mothers did not have musical background (NMB). SB increased in both groups. Mothers in the NMB group had greater probability to increase their light and moderate-to-vigorous PA and decrease their SB than mothers in the MB group. However, exercise adherence decreased considerably in all groups. Completeness, fidelity, and enjoyment were higher among the NMB group compared to the MB group. Conclusions The present results showed that mothers without musical background were more interested in movement-to-music exercises, as well as their children. For further studies it would be important to evaluate an effect of children’s own music-based activities on their SB and PA. PMID:29668726

Physical activity (PA) is recommended for managing osteoarthritis (OA). However, few people with OA are physically active. Understanding the factors associated with PA is necessary to increase PA in this population. This cross-sectional study examined factors associated with leisure-time PA, stretching exercises, and strengthening exercises in people with OA. For a mail survey, 485 individuals, aged 68.0 years (SD = 10.6) with hip or knee OA, were asked about factors that may influence PA participation, including use ofnon-PAOA management strategies and both psychological and physical health-related factors. Associations between factors and each PA outcome were examined in multivariable logistic regression models. Non-PA management strategies were the main factors associated with the outcomes. Information/education courses, heat/cold treatments, and paracetamol were associated with stretching and strengthening exercises (P < .05). Hydrotherapy and magnet therapy were associated with leisure-time PA; using orthotics and massage therapy, with stretching exercises; and occupational therapy, with strengthening exercises (P < .05). Few psychological or health-related factors were associated with the outcomes. Some management strategies may make it easier for people with OA to be physically active, and could be promoted to encourage PA. Providers of strategies are potential avenues for recruiting people with OA into PA programs.

Ideal approaches to increasing long-term physical activity (PA) adherence in women remain unclear. This study used a longitudinal mixed-methods approach to 1) determine the effectiveness of an 8-month book club intervention for increasing PA participation and self-worth, and reducing barriers at 1-year followup; and 2) identify reasons why completers and noncompleters did or did not maintain PA. One year after the cessation of Women Bound to be Active (WBA), completers (participated in posttesting; n = 30) and noncompleters (did not participate in posttesting; n = 22) responded to questionnaires and interviews assessing their body mass index (BMI), current PA participation, barriers, and global self-worth. Compared with noncompleters, completers reported decreases in BMI, higher motivation for PA, higher ratio of benefits to barriers, and more consistent PA. Both groups still reported barriers to PA, especially time; however, completers more often reported strategies for overcoming these barriers. Completers more directly discussed the impact of their improved self-worth on their PA participation. In the future, a greater focus on time management and self-regulation strategies should be emphasized in PA interventions, specifically those that focus on women. This may help to prevent program and long-term PA attrition.

The aims of this study were to describe physical activity (PA) prevalence and compare it with other countries and to investigate possible associations between PA and other lifestyle behaviors in Azorean adults. 9991 adults (5723 women), aged 37.8 +/- 9.5 years, of the 2004 Azorean Physical Activity and Health Study. IPAQ assessed PA. All other lifestyle behaviors (age, gender, education level, income, employment, marital status, number of children, meal frequency, sleep time, sitting time, body mass index and alcohol and tobacco consumptions) were also self-reported. 57.1% of the participants met current PA recommendations and 32.2% were categorized as Health Enhancing PA (HEPA). Women were less likely to achieve PA recommendations, as well as the HEPA level. In both genders, higher education level, employment status, higher income, and sitting for more than 3h/day were negative predictors of HEPA; and, having at least 5 meals/day was positive predictor for the same PA level. There is a significant proportion of Azoreans, particularly women, that does not do enough PA. Targeted programs for Azoreans aimed to increase PA levels should pay special attention on women, and consider a multifactorial approach, once several lifestyle behaviors seem to interact with PA levels, in this population.

Authorities recommend that schools provide a variety of opportunities for students to obtain physical activity (PA) before, during, and after school. This study assessed the prevalence of several school PA practices-including measures of quantity and quality of physical education (PE)-in elementary schools and examined the associations of PA practices with school resources (PE staffing, training, and facilities). Surveys were obtained from respondents in nationally representative samples of elementary schools from 2009-2010 to 2011-2012 (1,831 schools). Few schools (20.8%) provided students with PE class every day, but most (76.3%) had an appropriate PE student-to-teacher ratio ( ≤ 25:1). Many schools (74.0%) offered 20 min of recess daily, but fewer than half offered organized opportunities for PA before or after school (e.g., sports). After controlling for demographics and school size, having a full-time PE teacher and requiring PE teachers to obtain PE-related continuing education (CE) were associated with PE practices such as offering ≥ 150 min of PE per week (for 3rd-grade students) and testing PE knowledge, skills, and fitness. Required CE was also associated with a higher likelihood of offering PA during the school day (i.e., activity breaks and PA outside of PE class) and before or after the school day (i.e., afterschool PA programs). Few schools offer a broad array of PA programming. However, PE staffing and CE are positively associated with many PA practices including those outside of PE, possibly indicating that PE staff serve a crucial role in promoting a whole-school PA-supportive environment.

South Asian (SA) women in the United States report extremely low rates of leisure time physical activity (PA) compared with women in other ethnic minority groups. This study explored SA women's perspectives on PA during different life stages. This is a community-based participatory research study that used focus groups. The study setting was a community-based organization that provides social services to SA immigrants in Chicago, Illinois. The study team conducted six focus groups (in English and Hindi) with 42 SA women, ages 18 to 71 years. A semistructured interview guide was used to foster discussion about perceptions of, barriers to/facilitators of, and suggestions for PA programs. Discussions were transcribed and independently coded by two reviewers using thematic content analysis and guided by a coding scheme that was developed a priori. Participants said that different life stages strongly influenced their PA. PA decreased after marriage and having children. Chronic diseases constrained older women from more vigorous PA. Barriers to PA among younger women were family disapproval and perceptions that PA is unnecessary if you are "skinny." Women agreed that PA is not a priority within the culture, and that interventions must take into account cultural, religious, and family context. Sociocultural norms, family constraints, and lack of awareness about the benefits of PA strongly influenced PA among SA women. Culturally salient intervention strategies might include programs in trusted community settings where women can exercise in women-only classes with their children, and targeted education campaigns to increase awareness about the benefits of PA across life stages.

The purpose of this study was to evaluate associations between exposure to the Exercise Orientation Service (EOS) program and physical activity (PA) and quality of life (QoL) in adults from Vitoria, Brazil. A phone survey was conducted with 2023 randomly selected participants (≥ 18 years) to measure awareness about the program, participation in the program, PA levels, and QoL. The associations were tested using Poisson and Linear regression models. 31.5% reported awareness about the program, 1.5% reported current participation, and 5.8% reported previous participation. Participation was higher among women (2.1%), older subjects (2.8%), and those reporting morbidities (2.4%). Awareness was higher among middle-aged persons (36.0%) and highly educated participants (37.1%). Current participation (PR = 2.22; 95% CI = 1.65-2.99) and awareness (PR = 1.15; 95% CI = 1.02-1.30) were associated with leisure-time PA (LTPA). Exposure to the program was not associated with QoL but was consistently associated with sufficient levels of LTPA among adults from Vitoria, Brazil.

Few interventions to promote physical activity (PA) adapt dynamically to changes in individuals' behavior. Interventions targeting determinants of behavior are linked with increased effectiveness and should reflect changes in behavior over time. This article describes the application of two frameworks to assist the development of an adaptive evidence-based smartphone-delivered intervention aimed at influencing PA and sedentary behaviors (SB). Intervention mapping was used to identify the determinants influencing uptake of PA and optimal behavior change techniques (BCTs). Behavioral intervention technology was used to translate and operationalize the BCTs and its modes of delivery. The intervention was based on the integrated behavior change model, focused on nine determinants, consisted of 33 BCTs, and included three main components: (1) automated capture of daily PA and SB via an existing smartphone application, (2) classification of the individual into an activity profile according to their PA and SB, and (3) behavior change content delivery in a dynamic fashion via a proof-of-concept application. This article illustrates how two complementary frameworks can be used to guide the development of a mobile health behavior change program. This approach can guide the development of future mHealth programs.

Low physical activity (PA) and fruit and vegetable (F&V) consumption in early childhood are continued public health challenges. This manuscript describes outcomes from two pilot studies for Sustainability via Active Garden Education (SAGE), a program designed to increase PA and F&V consumption among 3 to 5 year old children. SAGE was developed using community-based participatory research (CBPR) and delivered to children (N = 89) in early care and education centers (ECEC, N = 6) in two US cities. Children participated in 12 one-hour sessions that included songs, games, and interactive learning activities involving garden maintenance and taste tests. We evaluated reach, efficacy, adoption, implementation, and potential for maintenance of SAGE following the RE-AIM framework. Reach was evaluated by comparing demographic characteristics among SAGE participants and residents of target geographic areas. Efficacy was evaluated with accelerometer-measured PA, F&V consumption, and eating in the absence of hunger among children, parenting practices regarding PA, and home availability of F&V. Adoption was evaluated by the number of ECEC that participated relative to the number of ECEC that were recruited. Implementation was evaluated by completion rates of planned SAGE lessons and activities, and potential for maintenance was evaluated with a parent satisfaction survey. SAGE reached ECEC in neighborhoods representing a wide range of socioeconomic status, with participants' sociodemographic characteristics representing those of the intervention areas. Children significantly increased PA during SAGE lessons compared to usual lessons, but they also consumed more calories in the absence of hunger in post- vs. pre-intervention tests (both p < .05). Parent reports did not suggest changes in F&V consumption, parenting PA practices, or home F&V availability, possibly due to low parent engagement. ECEC had moderate-to-high implementation of SAGE lessons and curriculum. Potential for maintenance was strong, with parents rating SAGE favorably and reporting increases in knowledge about PA and nutrition guidelines for young children. SAGE successfully translated national PA guidelines to practice for young children but was less successful with nutrition guidelines. High adoption and implementation and favorable parent reports suggest high potential for program sustainability. Further work to engage parents and families of young children in ECEC-based PA and nutrition programming is needed.

High rates of physical inactivity compromise the health status of populations globally. Social networks have been shown to influence physical activity (PA), but little is known about how best to engineer social networks to sustain PA. To improve procedures for building networks that shape PA as a normative behavior, there is a need for more specific hypotheses about how social variables influence PA. There is also a need to integrate concepts from network science with ecological concepts that often guide the design of in-person and electronically-mediated interventions. Therefore, this paper: (1) proposes a conceptual model that integrates principles from network science and ecology across in-person and electronically-mediated intervention modes; and (2) illustrates the application of this model to the design and evaluation of a social network intervention for PA. A conceptual model for engineering social networks was developed based on a scoping literature review of modifiable social influences on PA. The model guided the design of a cluster randomized controlled trial in which 308 sedentary adults were randomly assigned to three groups: WalkLink+: prompted and provided feedback on participants' online and in-person social-network interactions to expand networks for PA, plus provided evidence-based online walking program and weekly walking tips; WalkLink: evidence-based online walking program and weekly tips only; Minimal Treatment Control: weekly tips only. The effects of these treatment conditions were assessed at baseline, post-program, and 6-month follow-up. The primary outcome was accelerometer-measured PA. Secondary outcomes included objectively-measured aerobic fitness, body mass index, waist circumference, blood pressure, and neighborhood walkability; and self-reported measures of the physical environment, social network environment, and social network interactions. The differential effects of the three treatment conditions on primary and secondary outcomes will be analyzed using general linear modeling (GLM), or generalized linear modeling if the assumptions for GLM cannot be met. Results will contribute to greater understanding of how to conceptualize and implement social networks to support long-term PA. Establishing social networks for PA across multiple life settings could contribute to cultural norms that sustain active living. ClinicalTrials.gov NCT01142804.

The purpose of the study is to identify demographic, clinical, lifestyle-related, and social-cognitive correlates of physical activity (PA) intention and behavior in head and neck cancer (HNC) survivors using the theory of planned behavior (TPB). Data from two cross-sectional studies on correlates of PA in HNC survivors were pooled. Both studies used self-reports to assess PA and social-cognitive correlates. Potential correlates were collected via self-report or medical records. Univariable and multivariable multilevel linear mixed-effects models were built to identify correlates of PA intention and PA behavior (Z scores). Structural equation model analyses were conducted to study the full TPB model in one analysis, taking into account relevant covariates. In total, 416 HNC survivors were surveyed. Their mean (SD) age was 66.6 (9.4) years; 64% were men, and 78% were diagnosed with laryngeal cancer. The structural equation model showed that PA intention was significantly higher in HNC survivors with a history of exercising, who had a more positive attitude, subjective norm, and perceived behavioral control. Patients with higher PA intention, higher PBC, a lower age, and without unintentional weight loss or comorbidities had higher PA behavior. The model explained 22.9% of the variance in PA intention and 16.1% of the variance in PA behavior. Despite significant pathways of the TPB model, the large proportion variance in PA intention and behavior remaining unexplained suggests the need for better PA behavior (change) models to guide the development of PA promotion programs, particularly for the elderly. Such programs should be tailored to comorbidities and nutritional status.

This study analyzed psychosocial predictors of the Theory of Planned Behavior (TPB) and Self-Determination Theory (SDT) and evaluated their associations with short- and long-term moderate plus vigorous physical activity (MVPA) and lifestyle physical activity (PA) outcomes in women who underwent a weight-management program. 221 participants (age 37.6 ± 7.02 years) completed a 12-month SDT-based lifestyle intervention and were followed-up for 24 months. Multiple linear regression analyses tested associations between psychosocial variables and self-reported short- and long-term PA outcomes. Regression analyses showed that control constructs of both theories were significant determinants of short- and long-term MVPA, whereas affective and self-determination variables were strong predictors of short- and long-term lifestyle PA. Regarding short-term prediction models, TPB constructs were stronger in predicting MVPA, whereas SDT was more effective in predicting lifestyle PA. For long-term models, both forms of PA were better predicted by SDT in comparison to TPB. These results highlight the importance of comparing health behavior theories to identify the mechanisms involved in the behavior change process. Control and competence constructs are crucial during early adoption of structured PA behaviors, whereas affective and intrinsic sources of motivation are more involved in incidental types of PA, particularly in relation to behavioral maintenance. © The Author 2014.

Cancer and cancer treatment coincide with substantial negative physical, psychological and psychosocial problems. Physical activity (PA) can positively affect the negative effects of cancer and cancer treatment and thereby increase quality of life in CPS. Nevertheless, only a minority of CPS meet PA guidelines. We developed the OncoActive (OncoActief in Dutch) intervention: a computer-tailored PA program to stimulate PA in prostate and colorectal CPS, because to our knowledge there are only a few PA interventions for these specific cancer types in the Netherlands METHODS: The OncoActive intervention was developed through systematic adaptation of a proven effective, evidence-based, computer-tailored PA intervention for adults over fifty, called Active Plus. The Intervention Mapping (IM) protocol was used to guide the systematic adaptation. A literature study and interviews with prostate and colorectal CPS and health care professionals revealed that both general and cancer-specific PA determinants are important and should be addressed. Change objectives, theoretical methods and applications and the actual program content were adapted to address the specific needs, beliefs and cancer-related issues of prostate and colorectal CPS. Intervention participants received tailored PA advice three times, on internet and with printed materials, and a pedometer to set goals to improve PA. Pre- and pilot tests showed that the intervention was highly appreciated (target group) and regarded safe and feasible (healthcare professionals). The effectiveness of the intervention is being evaluated in a randomized controlled trial (RCT) (n = 428), consisting of an intervention group and a usual care waiting-list control group, with follow-up measurements at three, six and twelve months. Participants are recruited from seventeen hospitals and with posters, flyers and calls in several media. Using the Intervention Mapping protocol resulted in a systematically adapted, theory and evidence-based intervention providing tailored PA advice to prostate and colorectal CPS. If the intervention turns out to be effective in increasing PA, as evaluated in a RCT, possibilities for nationwide implementation and extension to other cancer types will be explored. The study is registered in the Dutch Trial Register (NTR4296) on November 23rd 2013 and can be accessed at http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=4296 .

Although there are substantial international differences in adolescent physical activity (PA), cross-country motivational differences have received limited attention, perhaps due to the lack of measures applicable internationally. Identical self-report measures assessing PA and motivations for PA were used to survey students ages 11, 13, and 15 from 7 countries participating in the 2005-2006 Health Behavior in School-Aged Children (HBSC) study representing 3 regions: Eastern Europe, Western Europe and North America. Multigroup comparisons with Confirmatory Factor Analysis and Structural Equation Modeling examined the stability of factors across regions and regional differences in relations between PA and motives for PA. Three PA motivation factors were identified as suitable for assessing international populations. There were significant regional, gender, and age differences in relations between PA and each of the 3 PA motives. Social and achievement motives were positively related to PA. However, the association of PA with health motivations varied significantly by region and gender. The patterns suggest the importance of social motives for PA and the possibility that health may not be a reliable motivator for adolescent PA. Programs to increase PA in adolescence need to determine which motives are effective for the particular population being targeted.

McDowell CHOICES (Coordinated Health Opportunities Involving Communities, Environments, and Schools) Project is a county wide endeavor aimed at increasing opportunities for physical activity (PA) in McDowell County, West Virginia (WV). A comprehensive needs-assessment laid the foundation of the project. During the 6 month needs assessment, multiple sources of data were collected in two Town Hall Meetings (n = 80); a student online PA interest survey (n = 465); a PA and nutrition survey among 5(th) (10-11 years) and 8(th) graders (13-14 years) with questions adapted from the CDC's Youth Risk Behavior Surveillance Survey (n = 442, response rate = 82.2%); six semi-structured school and community focus groups (n = 44); school site visits (n = 11); and BMI screening (n = 550, response rate = 69.7%). One third of children in McDowell County meet the national PA minimum of 60 minutes daily. At least 40% of 5(th) and 8(th) graders engage in electronic screen activity for 3 hours or more every day. The prevalence of obesity in 5(th) graders is higher in McDowell County than the rest of WV (~55% vs. 47% respectively). SWOT analyses of focus group data suggest an overall interest in PA but also highlight a need for increase in structured PA opportunities. Focus group data also suggested that a central communication (e.g. internet-based) platform would be beneficial to advertise and boost participation both in current and future programs. Schools were commonly mentioned as potential facilities for public PA participation throughout the county, both with regards to access and convenience. School site visits suggest that schools need more equipment and resources for before, during, and after school programs. An overwhelming majority of participants in the McDowell CHOICES needs assessment were interested to participate in more PA programs throughout the county as well as to improve opportunities for the provision of such programs. Public schools were widely recognized as the hub of the communities and provide the best venue for PA promotion for both students and adult citizens, and can potentially serve as a platform for change in rural communities such as McDowell County.

This study examined the effects of utilizing a wearable activity tracker in a credit-based physical activity instructional program (PAIP) for promoting physical activity (PA) in college students. Fourteen PAIP courses in a large public university were randomly assigned into intervention (k = 7; n = 101) and control (k = 7; n = 86) groups. All courses focused on a core curriculum that covers basic exercise and behavioral science contents through lectures and activity sessions. A Misfit Flash activity tracker was provided to students in the intervention group. Objective PA assessments occurred at baseline, mid-, and end-of-semester during a 15-week academic semester. The control group showed a significant reduction in moderate- and vigorous-intensity PA (MVPA) minutes from baseline to the end-of-semester (P <.05), whereas the intervention group showed no changes in MVPA minutes over time. However, the intervention group also showed increased sedentary time and decreased time spent in light-intensity PA during the intervention period. Taken together, the present study found null effects of utilizing the wearable activity tracker in promoting PA in college students suggesting that intervention of primary using the wearable activity tracker as a behavior change strategy may not be effective to increase in PA in this setting.

To evaluate the relationship between long-term maintenance of moderate to vigorous physical activity (MVPA) and clinical outcomes in fibromyalgia (FM). Patients with FM (n = 170) received individualized exercise prescriptions and completed baseline and followup physical activity assessments using the Community Health Activities Model Program for Seniors questionnaire at weeks 12, 24, and 36. The primary outcome was the change in the Fibromyalgia Impact Questionnaire-Physical Impairment (FIQ-PI) score. The secondary outcomes included improvements in overall well-being (FIQ total score), pain severity ratings, and depression. Using a threshold increase in MVPA of ≥10 metabolic equivalent hours/week above usual activities, 27 subjects (15.9%) increased and sustained (SUS-PA), 68 (40%) increased but then declined (UNSUS-PA), and 75 (44.1%) did not achieve (LO-PA) this benchmark. Compared to LO-PA subjects, both SUS-PA and UNSUS-PA subjects reported greater improvement in FIQ-PI (P < 0.01) and FIQ total score (P < 0.05). Additionally, the SUS-PA group reported greater improvement in pain severity compared to the LO-PA group (P < 0.05). However, there were no significant group differences between SUS-PA and UNSUS-PA for any primary or secondary outcome measure. Increased participation in MVPA for at least 12 weeks improved physical function and overall well-being in patients with FM. Although sustained physical activity was not associated with greater clinical benefit compared with unsustained physical activity, these findings also suggest that performing greater volumes of physical activity is not associated with worsening pain in FM. Future research is needed to determine the relationship between sustained MVPA participation and subsequent improvement in patient outcomes. Copyright © 2013 by the American College of Rheumatology.

This is the second Active Healthy Kids Wales Report Card. The 2016 version consolidates and translates research related to physical activity (PA) among children and youth in Wales, and aims to raise the awareness of children's engagement in PA and sedentary behaviors. Ten PA indicators were graded using the Active Healthy Kids-Canada Report Card methodology involving a synthesis and expert consensus of the best available evidence. Grades were assigned as follows: Overall PA, D+; Organized Sport Participation, C; Active and Outdoor Play, C; Active Transportation, C; Sedentary Behaviors, D-; Physical Literacy, INC; Family and Peer Influences, D+; School, B; Community and the Built Environment, C; and National Government Policy, Strategies, and Investments, B-. Despite the existence of sound policies, programs, and infrastructure, PA levels of children and youth in Wales are one of the lowest and sedentary behavior one of the highest globally. From the 2014 Report Card, the Family and Peer Influences grade improved from D to D+, whereas Community and the Built Environment dropped from B to C. These results indicate that a concerted effort is required to increase PA and decrease sedentary time in children and young people in Wales.

Physical activity (PA) plays an important role in the combat against noncommunicable diseases including cardiovascular diseases. In order to develop appropriate PA intervention programs, there is a need to evaluate PA behavior. So far, there are no published data on PA available for Suriname. Therefore, we aim to describe PA behavior among the multi-ethnic population living in urban and rural areas of Suriname. The World Health Organization (WHO) STEPwise approach to chronic disease risk factor surveillance (STEPS) was conducted in a national representative sample (N = 5751; 48.6% men) aged 15-64 years between March and September 2013. Physical activity data were assessed using the Global physical activity questionnaire (GPAQ) and analyzed according to the GPAQ guidelines. The prevalence of meeting the recommended PA level and prevalence ratios (PR) were computed. Only 55.5% of the overall population met the WHO recommended PA levels (urban coastal area: 55.7%, rural coastal area: 57.9%, rural interior area: 49.1%). Women were less likely to meet the recommended PA level (49% vs 62.4%; p < 0.0001) and with increasing age the PR for recommended level of PA decreased (p < 0.0001). Compared to the Hindustani's, the largest ethnic group, the Javanese reported the lowest percentage of people meeting recommended PA level (PR = 0.92; p = 0.07). Around half of the population meets the recommended PA level. Future lifestyle interventions aiming at increasing PA should especially focus on women and older individuals as they are less likely to meet the recommended levels of PA.

explaining why and how overweight prevention programs were effective was a real need; especially the potential role of physical activity (PA) and sedentary behavior (SB) should be highlighted. This study aimed to evaluate the 2-year effectiveness of a screening and care strategy in adolescents' weight reduction with regards to PA and SB change. 1745 adolescents aged 15.1 years from PRALIMAP trial was included (n = 840 for screening and care group and n = 905 for control group). PA and SB time (international physical activity questionnaire: IPAQ), body mass index (BMI), and BMI z-score were assessed at inclusion and after 2-year intervention. Hierarchical mixed models were applied. Compared with the control group, screening and care strategy was associated with an increase in global PA (58 min/week), a moderate PA (43 min/week), the adherence to the French PA guidelines (OR = 1.3), and a decrease in SB (-198 min/week). The 2-year weight change decreased when adjusted for PA and SB suggesting that the effect of screening and care strategy was partly mediated by PA and SB. Screening and care intervention seemed to be effective in increasing PA and decreasing SB. The induced PA and SB modifications contributed to the observed weight change.

Implementing a comprehensive school physical activity program (CSPAP) effectively addresses public health issues by providing opportunities for physical activity (PA). Grounded in the Diffusion of Innovations model, the purpose of this study was to identify how health promotion efforts facilitate opportunities for PA. Physical and health education teachers (N = 256) nationwide were surveyed using a CSPAP Index to identify teacher's efforts for providing opportunities for PA within a school setting. A hierarchical regression analysis revealed total number of PA opportunities was significantly predicted by teachers' health promotion efforts, p < .001. Sex and years of experience were not significant covariates, p = .35, in the final step of the model. Accounting for teaching environments, the model was significant, p < .001. The strongest predictors were the promotional efforts of PA for family and community, p < .001, PA for staff members, p < .01, PA during the school day, p < .05, and PA before school, p < .05. To increase PA opportunities for children in schools, emphasis should be placed on health promotion. This study confirms the importance of teachers involving family, community, and staff members as co-health promoters when trying to increase PA engagement surrounding schools. © 2016, American School Health Association.

Background Previous studies have shown that choice and self-initiated behavior change are important for increasing intrinsic motivation and physical activity (PA), however, little of this research has focused on underserved adolescents. Purpose This study examined the effects of a 4-week student-centered intervention on increasing PA in underserved adolescents. Methods Twenty-eight students in the intervention school were matched (on race, percentage on free or reduced-price lunch program, gender, and age) with 20 students from another school who served as the comparison group (30 girls, 18 boys; ages 10–12 years; 83% African American; 83% on free or reduced-price lunch). The student-centered intervention was consistent with self-determination (motivation) theory and social cognitive theory in that it emphasized increasing intrinsic motivation and behavioral skills for PA. Intervention adolescents took ownership in selecting a variety of PA activities in which to participate, and they generated coping strategies for making effective PA behavior changes. Results Intervention participants showed greater increases in accelerometer estimates of time spent in moderate PA, moderate-to-vigorous PA, and vigorous PA from baseline to Week 4 of the intervention than the comparison group. Intervention participants also showed greater increases in PA motivation and positive self-concept for PA than comparison adolescents. Conclusions This study provides preliminary evidence that increasing adolescent involvement and choice of activities may be important in developing future PA interventions for underserved adolescents.

To prospectively study the effects of an incentivized exercise program on physical activity (PA), quality of life (QOL), and burnout among residents and fellows (RFs) in a large academic medical center. In January 2011, all RFs at Mayo Clinic in Rochester, Minnesota (N=1060), were invited to participate in an elective, team-based, 12-week, incentivized exercise program. Both participants and nonparticipants had access to the same institutional exercise facilities. Regardless of participation, all RFs were invited to complete baseline and follow-up (3-month) assessments of PA, QOL, and burnout. Of the 628 RFs who completed the baseline survey (59%), only 194 (31%) met the US Department of Health and Human Services recommendations for PA. Median reported QOL was 70 on a scale of 1 to 100, and 182 (29%) reported at least weekly burnout symptoms. A total of 245 individuals (23%) enrolled in the exercise program. No significant differences were found between program participants and nonparticipants with regard to baseline demographic characteristics, medical training level, PA, QOL, or burnout. At study completion, program participants were more likely than nonparticipants to meet the Department of Health and Human Services recommendations for exercise (48% vs 23%; P<.001). Quality of life was higher in program participants than in nonparticipants (median, 75 vs 68; P<.001). Burnout was lower in participants than in nonparticipants, although the difference was not statistically significant (24% vs 29%; P=.17). A team-based, incentivized exercise program engaged 23% of RFs at our institution. After the program, participants had higher PA and QOL than nonparticipants who had equal exercise facility access. Residents and fellows may be much more sedentary than previously reported. Copyright © 2013 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc. All rights reserved.

Objective. To investigate the efficacy of using “Instagram application” with a “home-exercise program” as a motivational stimulus in improving physical activity (PA) adherence levels among female college students. Methods. Fifty-eight female undergraduate students with the mean age 20.3 ± 0.96 years participated. Participants were divided into two groups: intervention and the control group; both the groups received an exercise program and the intervention group was additionally motivated by “Instagram.” Adherence to PA was measured by using an adherence sheet. The Exercise Motivation Inventory (EMI-2) was used to assess the motivational factors. Results. The most frequent motivational factors were extrinsic as assessed using the EMI-2. “Positive health” was the most frequent factor mentioned of the two types with 47% of the sample. The intervention group adhered with 17% more to the activity program compared to the control group. Moreover, 72% of the participants in the intervention and control groups found the activity program flexible enough to be performed at home; they agreed about its effectiveness on adherence (53%). Conclusions. The use of Instagram with the home exercise program as a motivational modality could be attractive and effective to reinforce adherence and maintain an appropriate PA level.

The qualitative study described in this article investigated perceptions about environmental factors influencing physical activity (PA) among children from underserved neighborhoods known as colonias in the U.S.-Mexico border. Ten focus groups were conducted with 67 Mexican-American colonia children ages 8 to 13 living in one of the poorest border counties in the U.S. Analyses indicated that PA among children was influenced by neighborhood characteristics, including litter, speeding cars, unleashed dogs, and dark streets. The children also underlined intrapersonal and social environmental factors. Findings may inform policy makers and public health professionals about ways to promote PA among underserved children through urban planning and programs focusing on PA-supportive infrastructure, neighborhood safety, and family- and home-based physical activities.

The Step by Step self-help walking program plus a pedometer previously motivated a community sample of adults to be physically active for up to three months. This study evaluates the effect of enhancement of this program over an additional nine months in a workplace. A quasi-experimental trial was conducted. Staff defined as inactive received the three month walking program and a pedometer (standard), or the three month program plus four maintenance newsletters over nine months (standard+maintenance). After 12 months a follow-up interview was conducted. Measures included changes in self-reported minutes walking, minutes of moderate-vigorous physical activity (MVPA), total physical activity (PA) in the past week, and the proportion meeting public health recommendations by walking and total PA. Significant increases on all outcome measures were noted for all participants. There were no between group differences in walking minutes. However, the change in MVPA minutes was significantly higher in the standard+maintenance group compared with the standard group (118 min vs 69 min, P=0.029). No significant between group differences were observed for total PA (161 min vs 117 min, P=0.187). Wearing the pedometer at the month of the follow-up interview, and thinking that the pedometer was very useful, increased the likelihood of meeting public health recommendations (AOR=2.7 and 2.5) adjusting for other covariates. Dissemination of the Step by Step guidebook with pedometers in the workplace resulted in a long-term increase in PA of inactive employees with no extra support. Newsletters as a maintenance strategy had no additional benefits. Better outcomes were noted if the pedometer was used and was perceived as being very useful.

While emerging research supports a positive relationship between social capital and youth physical activity (PA), few studies have examined possible mechanisms explaining this relationship and no studies have focused on rural youth. In this study, we examined parents' support of children's PA as an intermediary factor linking social capital and youth PA in a largely rural cross sectional sample of American children aged 6- to 19-years and their parents/guardians (N=767 families) living in upstate New York. Parents completed a self-administered survey assessing demographic factors, perceived social capital, support for children's PA, and children's PA including time spent outdoors and days per week of sufficient PA. Structural equation modeling was used to test the hypothesis that higher social capital is linked with higher parental support for PA and, in turn, higher PA in children. Analyses were conducted separately for younger (6-12 years) and older (13-19 years) children and controlled for demographic factors (child age, household education, participation in a food assistance program) and perceived neighborhood safety. Anticipated relationships among social capital, parents' activity-related support, and children's PA were identified for older, but not younger children. Findings suggest that parent support for children's PA is one possible mechanism linking social capital and youth PA and the parents of adolescents may rely more heavily on cues from their social environment to shape their approaches to supporting their children's PA than parents of younger children.

Physical activity (PA) has documented health benefits, but older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance holds promise as a culturally appropriate form of PA that challenges individuals physically and cognitively. This paper describes a randomized controlled trial that will test the efficacy of BAILAMOS©, a 4-month Latin dance program followed by a 4-month maintenance program, for improving lifestyle PA and health outcomes. Older adults (n = 332), aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels, and at risk for disability will be randomized to one of two programs, a dance program or health education control group. BAILAMOS© is a 4-month program that meets two times per week for one hour per session. Dance sessions focus on instruction, including four styles of dance, and couples dancing. Bi-monthly “Fiestas de Baile” (dance parties) are also included, in which participants dance and practice what they have learned.. Monthly 1-hour discussion sessions utilize a Social Cognitive framework and focus on knowledge, social support, and self-efficacy to increase lifestyle PA. The health education control group will meet one time per week for two hours per session. Primary outcomes including PA changes and secondary outcomes including self-efficacy, physical function, cognitive function, and disability will be assessed at baseline, 4, and 8 months. It is hypothesized that PA, self-efficacy, physical function, cognitive function, and functional limitations and disability scores will be significantly better in the BAILAMOS© group at 4 and 8 months compared to the control group.

Although pole walking (PW) has the potential to be a useful health-enhancing physical activity (PA), little is known about by whom or how it is being practised. The aims of this study were to describe (1) the characteristics of PW leaders, pole walkers and PW programs in Australia, and (2) participants' perceptions of PW and their reasons for participation. In 2012, PW leaders (n=31) and walkers (n=107) completed self-administered surveys that included questions about participants' sociodemographic and health characteristics, PW programs and perceptions of PW. Data were analysed using SPSS. Leaders and walkers were generally born in Australia (leaders, 71%; walkers, 83%), older (leaders, 55 years [s.d. 11.5]; walkers, 65 years [s.d. 10.6]) and female (leaders, 77%; walkers, 79%). Most walkers (82%) walked regularly in groups, approximately once per week for about an hour, at light to moderate intensity. The program's aims most strongly endorsed by PW leaders were to increase participant enjoyment (90%), increase PA levels (81%), provide a positive social experience (77%) and increase PA confidence (71%). The most strongly endorsed motivations for PW among walkers were to remain physically active (63%), improve fitness (62%) and personal and social enjoyment (60%). In Australia, PW is being practised by a health conscious, older population. It is perceived as an enjoyable and health-enhancing outdoor activity. SO WHAT?: Health and exercise practitioners may find that PW is a beneficial form of PA for older Australians.

This study evaluated a culturally relevant, social cognitive theory-based, Internet-enhanced physical activity (PA) pilot intervention developed for overweight/obese African American (AA) female college students. Using a 3-month, single group, pretest-posttest design, participants accessed a culturally relevant PA promotion website and engaged in four moderate-intensity PA sessions each week. Study completers (n = 25, mean age = 21.9 years) reported a decrease in sedentary screen time (p < .0001); however, no changes in moderate-to-vigorous PA were reported (p = .150). A significant increase in self-regulation for PA (p < .0001) and marginally significant increases in social support (p = .052) and outcome expectations (p = .057) for PA were observed. No changes in body mass index (p = .162), PA enjoyment (p = .151), or exercise self-efficacy (p = .086) were reported. Findings of this exploratory study show some preliminary support for Internet-enhanced approaches to promote PA among overweight/obese AA women. Future studies with larger samples are needed to further explore culturally relevant Internet-enhanced PA programs in this underserved population. © The Author(s) 2014.

Physical inactivity is one of the most important contributors to the global burden of disease and has become a global public health priority. We review the evidence on physical activity (PA) interventions, actions, and strategies that have the greatest potential to increase PA at the population level. Using the socio-ecological framework to conceptualize PA interventions, we show that PA can be targeted at multiple levels of influence and by multiple sectors outside the health system. Examples of promoting PA on a national scale are presented from Finland, Canada, Brazil, and Colombia. A strong policy framework, consistent investment in public health programs, multi-sectoral support and actions, and good surveillance characterize each of these success stories. Increasing PA globally will depend on successfully applying and adapting these lessons around the world taking into account country, culture, and context. PMID:25304047

2018-06-01

In Germany, physician assistant (PA) is a comparatively young profession. The concept paper by the German Medical Association (BÄK) and the Federation of Statutory Health Insurance Physicians (KBV) from 2017 defines the new occupational profile in detail. In contrast, there is hardly any information on the day to day working life of a PA in Germany OBJECTIVE: The aim of this study was to map the employment reality of the PA graduates of the study program of the Baden-Wuerttemberg Cooperative State University Karlsruhe. Graduates of the PA study program were interviewed using the web-based evaluation system EvaSys V7.1 (Electric Paper Evaluationssysteme GmbH, Lüneburg, Deutschland) in the spring of 2018. The information was evaluated descriptively. The response rate was 70% (48 out of 69 graduates), 44 graduates were employed as a PA and 27 worked in a surgical department. The core tasks of the surgically active PA, which were often performed to varying frequency included assisting surgery and the performance of simple wound closures. In addition, activities in the areas of documentation, communication and information sharing were emphasized. The average salary of a surgical PA was 3718 €. This amount was rated by 44.4% as appropriate or very appropriate. The current occupational situation for 81.5% of the study participants was much better or better than expected before the start of their PA studies. Overall satisfaction was very high: 85.1% of the graduates were satisfied to very satisfied. The graduates' level of job satisfaction is remarkable. Many of the activities mentioned in the concept paper of the BÄK and KBV were carried out frequently or very frequently by the PA. Nonetheless, the PA profession has significant development potential, especially in the realm of surgical PAs.

Evidence is mounting on the association between the built environment and physical activity (PA) with a call for intervention research. A broader approach which recognizes the role of supportive environments that can make healthy choices easier is required. A systematic review was undertaken to assess the effectiveness of interventions to encourage PA in urban green space. Five databases were searched independently by two reviewers using search terms relating to 'physical activity', 'urban green space' and 'intervention' in July 2014. Eligibility criteria included: (i) intervention to encourage PA in urban green space which involved either a physical change to the urban green space or a PA intervention to promote use of urban green space or a combination of both; and (ii) primary outcome of PA. Of the 2405 studies identified, 12 were included. There was some evidence (4/9 studies showed positive effect) to support built environment only interventions for encouraging use and increasing PA in urban green space. There was more promising evidence (3/3 studies showed positive effect) to support PAprograms or PA programs combined with a physical change to the built environment, for increasing urban green space use and PA of users. Recommendations for future research include the need for longer term follow-up post-intervention, adequate control groups, sufficiently powered studies, and consideration of the social environment, which was identified as a significantly under-utilized resource in this area. Interventions that involve the use of PA programs combined with a physical change to the built environment are likely to have a positive effect on PA. Robust evaluations of such interventions are urgently required. The findings provide a platform to inform the design, implementation and evaluation of future urban green space and PAintervention research. Copyright © 2014 Elsevier Ltd. All rights reserved.

2016-02-01

Among a group of First Nations youth, this research aimed to obtain objective measures of anthropometry, physical activity (PA) and fitness; to identify any group-level differences by sex, body mass index, waist circumference and body fat categories; to assess the barriers and supports to PA. Youth participated in anthropometric measures (BMI, waist circumference, body fat percentage), PA assessment (3 days of accelerometry) and fitness testing (guided by the Canadian Physical Activity, Fitness and Lifestyle Approach). Barriers and supports were assessed via environmental scan and focus groups. Descriptive statistics were compared to reference data. Group differences by sex, BMI status, waist circumference and body fat categories were tested using Mann-Whitney U and Chi square tests (p ≤ 0.05). Qualitative data were assembled into one file and coded manually for categories and themes. Seventy-two youth (12.1 ± 1.1 years, 61.1% male) participated in at least one measure; 36 completed the accelerometry. Sixty-three percent were overweight or obese, 51% were abdominally obese and 21% had excess body fat. Most (86.1%) met Canada's PA guidelines. Boys were more active than girls (p = 0.025) and had greater cardiorespiratory endurance (p = 0.003). Overweight, obese, or abdominally obese youth had lower cardiorespiratory endurance than normal weight youth (p < 0.001). Barriers and supports fell under the main themes: motivation, role models, personnel and facilities, environment and programs. Based on this assessment, youth in this community are active, but not sufficiently physically fit, especially among those affected by obesity and abdominal obesity. The findings, in addition to the numerous barriers to PA, support the community's desire for school-based PA programming.

In this review, we identify the health benefits associated with physical activity (PA); address the physical activity and sedentary guidelines issued by public health scientists as well as children's compliance to these guidelines; discuss the importance of motor skill acquisition during early childhood; and identify different settings that contribute to physical activity participation and strategies for improving PA in these settings. Results show that regular participation in PA during childhood has numerous immediate benefits, including positive changes in adiposity, skeletal health, psychological health, and cardiorespiratory fitness. Additionally, motor skill development during early childhood may have immediate health benefits as well as long-lasting effects in adulthood. Furthermore, the benefits of PA during childhood also appear to positively influence adult health outcomes, such as increased bone mineral density. Key environmental settings that have been shown to influence children's PA behavior include child care, active commuting to and from school, school recess, school physical education, after-school programs, churches, medical settings, and the home environment. Recommendations for practitioners and researchers are discussed. Copyright © 2012 S. Karger AG, Basel.

Engineering online and in-person social networks to sustain physical activity: application of a conceptual model

PubMed Central

2013-01-01

Background High rates of physical inactivity compromise the health status of populations globally. Social networks have been shown to influence physical activity (PA), but little is known about how best to engineer social networks to sustain PA. To improve procedures for building networks that shape PA as a normative behavior, there is a need for more specific hypotheses about how social variables influence PA. There is also a need to integrate concepts from network science with ecological concepts that often guide the design of in-person and electronically-mediated interventions. Therefore, this paper: (1) proposes a conceptual model that integrates principles from network science and ecology across in-person and electronically-mediated intervention modes; and (2) illustrates the application of this model to the design and evaluation of a social network intervention for PA. Methods/Design A conceptual model for engineering social networks was developed based on a scoping literature review of modifiable social influences on PA. The model guided the design of a cluster randomized controlled trial in which 308 sedentary adults were randomly assigned to three groups: WalkLink+: prompted and provided feedback on participants’ online and in-person social-network interactions to expand networks for PA, plus provided evidence-based online walking program and weekly walking tips; WalkLink: evidence-based online walking program and weekly tips only; Minimal Treatment Control: weekly tips only. The effects of these treatment conditions were assessed at baseline, post-program, and 6-month follow-up. The primary outcome was accelerometer-measured PA. Secondary outcomes included objectively-measured aerobic fitness, body mass index, waist circumference, blood pressure, and neighborhood walkability; and self-reported measures of the physical environment, social network environment, and social network interactions. The differential effects of the three treatment conditions on primary and secondary outcomes will be analyzed using general linear modeling (GLM), or generalized linear modeling if the assumptions for GLM cannot be met. Discussion Results will contribute to greater understanding of how to conceptualize and implement social networks to support long-term PA. Establishing social networks for PA across multiple life settings could contribute to cultural norms that sustain active living. Trial registration ClinicalTrials.gov NCT01142804 PMID:23945138

2015-01-01

Physical activity (PA) has a positive effect on the cardiorespiratory fitness, lung cancer symptoms, and quality of life of lung cancer patients. The aim of our study was to identify barriers to, and facilitators of PA in lung cancer patients. We collected data from five patients diagnosed with primary, advanced non-small-cell lung cancer (NSCLC) who were receiving chemotherapy. Choosing a qualitative approach, we conducted an exploratory analysis using the thematic analysis technique to process the data. Seven barriers to, and facilitators of PA were identified and grouped into four categories. We found that psychological and social factors affect patients' willingness and ability to engage in PA, while physiological and environmental factors have an impact on the duration, intensity, and regularity of their PA. Our study highlighted some of the effects that the barriers to PA have on the practice of it in our patient group. Our findings may be used by professionals to design adapted PA programs.

A multilevel examination of gender differences in the association between features of the school environment and physical activity among a sample of grades 9 to 12 students in Ontario, Canada

PubMed Central

2012-01-01

Background Creating school environments that support student physical activity (PA) is a key recommendation of policy-makers to increase youth PA. Given males are more active than females at all ages, it has been suggested that investigating gender differences in the features of the environment that associate with PA may help to inform gender-focused PA interventions and reduce the gender disparity in PA. The purpose of this cross-sectional study was to explore gender differences in the association between factors of the school environment and students' time spent in PA. Methods Among a sample of 10781 female and 10973 male students in grades 9 to 12 from 76 secondary schools in Ontario, Canada, student- and school-level survey PA data were collected and supplemented with GIS-derived measures of the built environment within 1-km buffers of the 76 schools. Results Findings from the present study revealed significant differences in the time male and female students spent in PA as well as in some of the school- and student-level factors associated with PA. Results of the gender-specific multilevel analyses indicate schools should consider providing an alternate room for PA, especially for providing flexibility activities directed at female students. Schools should also consider offering daily physical education programming to male students in senior grades and providing PA promotion initiatives targeting obese male students. Conclusions Although most variation in male and female students' time spent in PA lies between students within schools, there is sufficient between-school variation to be of interest to practitioners and policy-makers. More research investigating gender differentials in environment factors associated with youth PA are warranted. PMID:22272717

2006-01-01

Because physical inactivity poses serious health risks, interventions are urgently needed to reverse the increasingly sedentary lifestyles of adolescent girls. The aim of this study was to determine the feasibility of "Girls on the Move," an individually tailored computerized physical activity (PA) program plus nurse counseling intervention, in increasing PA. A pretest-posttest control group design was used with 77 racially diverse sedentary girls in Grades 6, 7, and 8 from two middle schools. Each of the instructional grades was randomly assigned to either an intervention or control condition. After completing computerized questionnaires, each girl in the control group received a handout listing the PA recommendations. To encourage PA, each girl in the intervention group received computerized, individually tailored feedback messages based on her responses to the questionnaires, individual counseling from the school's pediatric nurse practitioner (PNP), and telephone calls and mailings from a trained research assistant. At 12 weeks, girls in both groups responded to the questionnaires. No differences in self-reported PA emerged between the intervention and control groups at Weeks 1 (baseline) and 12 (postintervention). Repeated measures ANOVA showed a significant interaction between group and time for social support for PA, F(1, 69) = 5.73, p = .019, indicating that the intervention group had significantly greater social support across time than did the control group. From baseline to postintervention, social support increased for the intervention group but decreased for the control group. Reasons for the lack of significant differences between the groups on the PA measures were cited. Important information that could inform subsequent studies that test interventions to increase youth PA was acquired from conducting this study. Future efforts to increase PA participation might include this approach for enhancing social support for PA.

This study examined whether specific worksite supports for physical activity (PA) were associated with total and domain-specific PA. A cross-sectional, telephone-based study was conducted in four Missouri, USA, metropolitan areas in 2012 and 2013. Outcome variables included total PA and sub-domains (leisure, work, travel) measured using the International Physical Activity Questionnaire. Logistic regression determined odds of meeting PA recommendations, given access to and use of 18 unique PA worksite supports. A subsample of 119 participants also wore hip accelerometry for seven consecutive days and maintained a wear-time diary. Access to worksite supports were associated with odds of meeting objective moderate and vigorous (MV) PA above 150 min per week. Among 2013 survey participants, meeting PA recommendations while performing work-related tasks was significantly associated with several supports (e.g., walking maps, stair prompts), as was meeting recommendations during travel (e.g., flextime for PA, incentives for public transportation, walking/bicycling to work). Access to 11 worksite supports increased odds of meeting PA recommendations through leisure-time PA; five supports were associated with total PA. There were significant differences between access to and use of supports. Using objective MVPA, access to worksite challenges and bike storage were significantly associated with five and three times greater odds of meeting 150 min of MVPA per week, respectively. Worksite wellness plans are increasing across the US and employers are eager for evidence-based supports for increasing PA. This study provides insights into the utility of multiple worksite supports for PA to increase odds that employees meet PA recommendations.

The role of physical activity in improving physical fitness in children with intellectual and developmental disabilities.

One in three children in North America are considered overweight or obese. Children with intellectual and developmental disabilities (IDD) are at an increased risk for obesity than their typically developing peers. Decreased physical activity (PA) and low physical fitness may be contributing factors to this rise in obesity. Because children with IDD are at an increased risk of diseases related to inactivity, it is important to improve health-related physical fitness to complete activities of daily living and improve health. The focus of this research is on improving the performance of physical fitness components through physical activity programming among a group of children with IDD, ages 7-12 years. The Brockport Physical Fitness Test was used assess levels of physical fitness of 35 children with IDD (25 boys, 10 girls) before and after participation in a 10-week program. The results of paired sampled t-tests showed participation in 15-h PA program can significantly increase aerobic capacity and muscular strength and endurance in children with IDD. This study is aimed at understanding the role of PA in helping children with IDD to develop the fitness capacities essential to participation in a wide variety of activities.

Small sustainable monetary incentives versus charitable donations to promote exercise: Rationale, design, and baseline data from a randomized pilot study.

Regular physical activity (PA) enhances weight-loss and reduces risk of chronic disease. However, as few as 10% of U.S. adults engage in regular PA. Incentive programs to promote PA have shown some promise, but have typically used incentives that are too large to sustain over time and have not demonstrated habit formation or been tested in community settings. This report presents the rationale and design of a randomized pilot study testing the feasibility and preliminary efficacy of small monetary incentives for PA (n=25) versus charitable donations in the same amount (n=25) versus control (n=25) over 12months among 75 low-active but otherwise healthy adults at a local YMCA. Incentives are based on YMCA attendance, which is verified by electronic swipe card data and is the primary study outcome, with self-reported minutes/week of PA assessed as a secondary outcome. Incentives are intentionally small enough-$1/session, maximum of $5/week-such that they could be indefinitely sustained by community organizations, privately-owned health clubs, healthcare organizations, or employers (e.g., employer fitness facilities). Costs of the incentive program for the sponsoring organization may be partially offset by increases in membership resulting from the appeal of the program. Moreover, if efficacious, the charitable donation incentive program may have the added benefit of building social capital for the sponsoring organization and potentially serving as a tax write-off, thus further offsetting the cost of the incentives. Findings will also have implications for the use of financially sustainable community-based incentive programs for other health-related behaviors (e.g., weight loss, smoking).

While neighborhood design can potentially influence routine outdoor physical activities (PA), little is known concerning its effects on such activities among older adults attempting to increase their PA levels. We evaluated the effects of living in neighborhoods differing in compactness on changes in routine outdoor activities (e.g., walking, gardening, yard work) among older adults at increased mobility disability risk participating in the LIFE-Pilot PA trial (2003–07; ages 70–89 years; from Dallas, TX, San Francisco Bay area, Pittsburgh, PA, and Winston-Salem, NC). Analyses were conducted on the 400 LIFE-Pilot participants randomized to a one-year endurance-plus-strengthening PA intervention or health education control that completed one-year PA assessment (CHAMPS questionnaire). Outcomes of interest were exercise and leisure walking, walking for errands, and moderate-intensity gardening. Neighborhood compactness was assessed objectively using geographic information systems via a subsequent grant (2008–12). PA increased weekly exercise and leisure walking relative to control, irrespective of neighborhood compactness. However, walking for errands decreased significantly more in PA relative to control (net mean[SD] difference=16.2 minutes/week[7.7], p=.037), particularly among those living in less compact neighborhoods (net mean[SD] difference=29.8[10.8] minutes/week, p=.006). PA participants living in less compact neighborhoods maintained or increased participation in gardening and yard work to a greater extent than controls (net mean[SD] difference=29.3[10.8] minutes/week, p=.007). The results indicate that formal targeting of active transport as an adjunct to structured PA programs may be important to diminish potential compensatory responses in functionally impaired older adults. Structured endurance-plus-strengthening PA may help older adults maintain or increase such routine activities over time. Trial Registration clinicaltrials.gov Identifier= NCT01072500 PMID:28039068

Background Internet-based physical activity (PA) and weight management programs have the potential to improve employees’ health in large occupational health settings. To be successful, the program must engage a wide range of employees, especially those at risk of weight gain or ill health. Objective The aim of the study was to assess the use and nonuse (user attrition) of a Web-based and monitoring device–based PA and weight management program in a range of employees and to determine if engagement with the program was related to the employees’ baseline characteristics or measured outcomes. Methods Longitudinal observational study of a cohort of employees having access to the MiLife Web-based automated behavior change system. Employees were recruited from manufacturing and office sites in the North West and the South of England. Baseline health data were collected, and participants were given devices to monitor their weight and PA via data upload to the website. Website use, PA, and weight data were collected throughout the 12-week program. Results Overall, 12% of employees at the four sites (265/2302) agreed to participate in the program, with 130 men (49%) and 135 women (51%), and of these, 233 went on to start the program. During the program, the dropout rate was 5% (11/233). Of the remaining 222 Web program users, 173 (78%) were using the program at the end of the 12 weeks, with 69% (153/222) continuing after this period. Engagement with the program varied by site but was not significantly different between the office and factory sites. During the first 2 weeks, participants used the website, on average, 6 times per week, suggesting an initial learning period after which the frequency of website log-in was typically 2 visits per week and 7 minutes per visit. Employees who uploaded weight data had a significant reduction in weight (−2.6 kg, SD 3.2, P< .001). The reduction in weight was largest for employees using the program’s weight loss mode (−3.4 kg, SD 3.5). Mean PA level recorded throughout the program was 173 minutes (SE 12.8) of moderate/high intensity PA per week. Website interaction time was higher and attrition rates were lower (OR 1.38, P= .03) in those individuals with the greatest weight loss. Conclusions This Web-based PA and weight management program showed high levels of engagement across a wide range of employees, including overweight or obese workers, shift workers, and those who do not work with computers. Weight loss was observed at both office and manufacturing sites. The use of monitoring devices to capture and send data to the automated Web-based coaching program may have influenced the high levels of engagement observed in this study. When combined with objective monitoring devices for PA and weight, both use of the website and outcomes can be tracked, allowing the online coaching program to become more personalized to the individual.

The positive health impact of physical activity (PA) is well known, yet a large proportion of the world's population remains sedentary. General PA programs are common as health promotion initiatives. However, effectiveness evaluations of such PA programs on individual and organizational aspects, which could inform the decision-making process of public health bodies are still lacking, particularly in the most socially disadvantaged areas, where health promotion schemes are particularly needed. The aim of this study was to assess the effectiveness of a Guided Walking Program in a high social vulnerability context. A quasi-experimental, mixed methods study was conducted. The program had a duration of 6 months and a 6-month follow-up period after the intervention. Session frequency was five times a week, where sessions consisted of supervised PA combined with educational sessions. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework was followed to assess the program. The International Physical Activity Questionnaire (IPAQ) and accelerometers were used to measure levels of PA. Focus groups were conducted to gain a comprehensive insight on the implementation domain. Most subjects in the intervention (IG) (n = 74) and control (CG) (n = 74) groups were female (IG:90.5%; CG:95.9%), aged 18-49 years (IG:44.6%; CG:43.2%), received less than 1 minimum wage (IG:74.3%; CG:83.7%) and had 0-4 years of formal education (IG:52.1%; CG:46.1%). The reach of the intervention was 0.3%. The IG showed increased levels of PA at post-intervention and 6-month follow-up. However, the difference between groups was not statistically significant. Adoption data revealed that 89.5% of the professionals in the Primary Health Care Center (health center) team perceived the benefits of the program for the population. The program was independently promoted by the health center team for a further 4 months post-intervention. The qualitative data revealed that the program was discontinued due to participants' low adherence and human resource limitations in the unit's operational dynamics. A health promotion intervention in a socially deprived setting faces challenges but can be effective and feasible to implement. The present study informs the development of future health promotion initiatives in this context. NCT02857127 . Registered: 30 July 2016 (retrospectively registered).

To create guidelines focused on the use of structured physical activity (PA) in the management of juvenile idiopathic arthritis (JIA). A systematic literature search was conducted using the electronic databases Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), EMBASE (Ovid), and Physiotherapy Evidence Database for all studies related to PA programs for JIA from January 1966 until December 2014, and was updated in May 2015. Study selection was completed independently by 2 reviewers. Studies were included if they involved individuals aged ≤21 years diagnosed with JIA who were taking part in therapeutic exercise or other PA interventions for which effects of various disease-related outcomes were compared with a control group (eg, no PA program or activity of lower intensity). Two reviewers independently extracted information on interventions, comparators, outcomes, time period, and study design. The statistical analysis was reported using the Cochrane Collaboration methods. The quality of the included studies was assessed according to the Physiotherapy Evidence Database Scale. Five randomized controlled trials (RCTs) fit the selection criteria; of these, 4 were high-quality RCTs. The following recommendations were developed: (1) Pilates for improving quality of life, pain, functional ability, and range of motion (ROM) (grade A); (2) home exercise program for improving quality of life and functional ability (grade A); (3) aquatic aerobic fitness for decreasing the number of active joints (grade A); and (4) and cardio-karate aerobic exercise for improving ROM and number of active joints (grade C+). The Ottawa Panel recommends the following structured exercises and physical activities for the management of JIA: Pilates, cardio-karate, home and aquatic exercises. Pilates showed improvement in a higher number of outcomes. Copyright © 2017. Published by Elsevier Inc.

To evaluate the long-term cost-effectiveness of two home-based cardiac rehabilitation (CR) interventions (Healthy Weight (HW) and Physical Activity (PA)) for patients with cardiovascular disease (CVD), who had been referred to cardiac rehabilitation (CR) but had not attended. The interventions consisted of pedometer-based telephone coaching sessions on weight, nutrition and physical activity (HW group) or physical activity only (PA group) and were compared to a control group who received information brochures about physical activity. A cost-effectiveness analysis was conducted using data from two randomised controlled trials. One trial compared HW to PA (PANACHE study), and the second compared PA to usual care. A Markov model was developed which used one risk factor, body mass index (BMI) to determine the CVD risk level and mortality. Patient-level data from the trials were used to determine the transitions to CVD states and healthcare related costs. The model was run for separate cohorts of males and females. Univariate and probabilistic sensitivity analysis were conducted to test the robustness of the results. Given a willingness-to-pay threshold of $50,000/QALY, in the long run, both the HW and PA interventions are cost-effective compared with usual care. While the HW intervention is more effective, it also costs more than both the PA intervention and the control group due to higher intervention costs. However, the HW intervention is still cost-effective relative to the PA intervention for both men and women. Sensitivity analysis suggests that the results are robust. The results of this paper provide evidence of the long-term cost-effectiveness of home-based CR interventions for patients who are referred to CR but do not attend. Both the HW and PA interventions can be recommended as cost-effective home-based CR programs, especially for people lacking access to hospital services or who are unable to participate in traditional CR programs.

VanDerworp, Gwendolyn Kay; Ryan, Sarah-Jane

2016-03-01

Childhood physical activity (PA) has declined in the western world recently. To combat child inactivity, government programs have been organized to promote PA within families. It is important for physiotherapists to understand the influence parents perceive to have on their child's PA habits in order to better encourage a positive parental influence. The purpose of this study is to explore how parents perceive their influence on their child/children's PA through an interpretative phenomenological analysis (IPA) approach. This qualitative study used a phenomenological approach with semi-structured interviews conducted with five participants. The interviews were analyzed using elements of IPA. Master themes developed with their corresponding subthemes: creating an environment of opportunity--logistics, opportunities through encouragement and PA within the family, barriers to PA--barriers created by parents and barriers created by external factors, and parent and child interactions--children communicating interest and disinterest in PA and parent's attitudes toward children's disinterest. The findings suggest that parents perceive themselves to have a greater positive influence on their children rather than negative. The barriers that parents create are not perceived to prevent their child's PA but rather restrict it. Many participants reported enjoying doing PA with their children and used PA as an opportunity for family time, indicating a dual purpose for PA. © The Author(s) 2014.

Low levels of physical activity (PA) and highly sedentary leisure habits (SLH) in youth may establish behavioral patterns that will predispose youth to increased chronic disease risk in adulthood. The purpose of this paper was to examine associations of demographic and psychosocial factors with self-reported PA and SLH in young adolescents. A general linear mixed model predicted self-reported PA and SLH in the spring from demographic and psychosocial variables measured the previous fall in 3798 seventh grade students. PA and SLH differed by race, with Caucasian students reporting among the highest PA and lowest SLH. Perceptions of higher academic rank or expectations predicted higher PA and lower SLH. Depressive symptomatology predicted higher SLH scores but not PA. Higher self-reported value of health, appearance, and achievement predicted higher PA and lower SLH in girls. Girls who reported that their mothers had an authoritative parenting style also reported higher PA and lower SLH. Determinants of PA and SLH appear to differ from each other, particularly in boys. Development of effective programs to increase PA and/or decrease SLH in young adolescents should be based on a clear understanding of the determinants of these behaviors.

Physical activity (PA) has myriad benefits for children with disabilities (CWD). Information and messaging campaigns can promote PA among CWD. The overall purpose of the study was to gain an understanding of the development of PA information and messages targeting parents of CWD. The specific objectives were to identify parents' preferences regarding PA information and messaging content and preferred methods and sources of communication. Focus groups were conducted with parents of CWD (N=28). Qualitative data were collected and transcribed. Inductive content analyses were employed to identify key themes. Three key thematic areas were identified: 1) Preferred content (e.g., targeted information, self-regulatory strategies, inclusive images), 2) Challenges (e.g., lack of information and language clarity), 3) Preferred sources (e.g., other parents, reliable organizations, central information hub). Parents' needs and preferences regarding PA information could be incorporated into campaigns to enhance parent PA support and PA among CWD. Stakeholders (e.g., PA organizations, programs and practitioners) can employ these strategies in campaigns and resources targeting parents of CWD. Research is necessary to empirically develop and evaluate PA information and messaging campaigns targeting parents of CWD. Copyright © 2017 Elsevier Ltd. All rights reserved.

Regular physical activity (PA) has been shown to reduce risk of morbidity and overall mortality. A study has displayed that achieving 10,000 steps/day is associated with important health outcomes and have been used to promote PA. Pedometers are a popular tool for PA interventions in different setting. This study investigated the effects on pedometer-based and self-reported PA among Tabriz University employees. This experimental study assessed the effects of 16 weeks pedometer-based workplace intervention. Participants (n = 154) were employees of two worksites. Pedometer-based and self-reported PA from one intervention worksite was compared with the data of a comparison workplace. International Physical Activity Questionnaire (IPAQ) for self-reported measure of PA, and demographic (age, marital status, educational level, employment status, and stage of change) variables were obtained. To measure PA objectively pedometer was used. Participants reported to increase the step counts from baseline (end of summer) to posttest (winter). The intervention effect revealed significant increase in the intervention group (8279 ± 2759 steps/day than in the comparison work place (4118 ± 1136). Self-reported based on IPAQ concluded women in intervention worksite had a significant increase in the leisure time domain, but similar finding was not found in the comparison worksite. Pedometer used might rather benefit those individuals who want feedback on their current PA, also walking should be considered to increase PA in employee women.

To determine the relationship between physical activity (PA) and health-related quality of life among university employees who enrolled in a worksite wellness program (WWP). The study was an interim analysis of data collected in a WWP. The sample consisted of 64 participants who completed 12- and 26-week follow-up appointments. Self-reported anxiety days significantly decreased from baseline to week 12. There were positive trends in self-rated health, vitality days, and summative unhealthy days from baseline to week 26. Among those with a self-reported history of hypertension (HTN), there was an inverse correlation between PA and summative physically and mentally unhealthy days at week 12. Among participants in this WWP with HTN, as PA increased there was a significant decrease in summative physically and mentally unhealthy days at week 12.

Despite its well-established benefits, physical activity (PA) engagement is low in the adult population; evidence suggests that this is especially a concern for women > 60 years. The purpose of this mixed methods study was to explore the feasibility of a six-week randomized control trial of Self-Determination Theory-based dance and walking programs for older women. Primary outcomes were feasibility measures: recruitment, retention, and satisfaction. Secondary outcomes included self-reported PA, behavioural regulations, and psychological needs. Thirty-five women completed the study (M = 62.8 ± 4.8 years), representing 39% recruitment and 95% retention rate. Both programs were highly attended. Exploratory effect sizes for secondary measures were promising. Emergent themes highlighted the importance of servant leadership concepts in the group setting for motivating PA. Our findings provide support for expanding this trial to a full-scale study.

Background Physical activity (PA) promotion has proven effectiveness in preventing childhood obesity. Increasing children’s health knowledge is the most frequently used approach in PA intervention programs targeting childhood obesity prevention. However, little is known about the specific association between the change in a child’s knowledge awareness and their PA practice. Methods A one-year follow-up study was conducted among primary and junior high school students in Nanjing, China. At baseline students’ knowledge of healthy behavior, and their PA levels, were assessed. Students who were unaware of the association between PA and obesity were followed for one academic year. After nine-months their knowledge and PA levels were re-measured using the same validated questionnaire. Mixed effects regression models were used to estimate the relationship between awareness of knowledge about the link between PA and obesity and PA changes. Results Of the 1899 students who were unaware of the association between PA and obesity at baseline, 1859 (follow-up rate = 97.9%) were successfully followed-up. After nine months 1318 (70.9%) participants had become aware of PA-obesity association. Compared to their counterparts who remained unaware, students who became aware of the PA-obesity association were more likely to increase both the frequency (odds ratio (OR) = 1.34, 95%CI = 1.09, 1.64) and duration (OR = 1.34, 95%CI = 1.09, 1.65) of PA, after adjusting for potentially confounding variables. Conclusion Becoming aware of the known link between PA and obesity led to positive behavior modification regarding PA in this cohort of Chinese students. This is of particular importance that knowledge disimination and health education may be a useful approach for population-based physical activity promotion aiming at childhood obesity prevention in China.

Child and adolescent obesity predisposes individuals to an increased risk of morbidity and mortality from a range of lifestyle diseases. Although there is some evidence to suggest that rates of pediatric obesity have leveled off in recent years, this has not been the case among youth from low socioeconomic backgrounds. The purpose of this paper is to report the rationale, study design and baseline findings of a school-based obesity prevention program for low-active adolescent girls from disadvantaged secondary schools. The Nutrition and Enjoyable Activity for Teen Girls (NEAT Girls) intervention will be evaluated using a group randomized controlled trial. NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions, interactive seminars, nutrition workshops, lunch-time physical activity (PA) sessions, PA and nutrition handbooks, parent newsletters, pedometers for self-monitoring and text messaging for social support. The following variables were assessed at baseline and will be completed again at 12- and 24-months: adiposity, objectively measured PA, muscular fitness, time spent in sedentary behaviors, dietary intake, PA and nutrition social-cognitive mediators, physical self-perception and global self-esteem. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored. NEAT Girls is an innovative intervention targeting low-active girls using evidence-based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status. Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an important contribution to the field.

2017-01-01

The purpose of this study was to examine the relationship of meeting the recommended levels of physical activity (PA) with health status and preventive health behavior in adults. A total of 5630 adults 18 years of age or older were included in this study. PA was assessed using a series of questions that categorized activities based on their metabolic equivalent values and then categorized individuals based on the reported frequency and duration of such activities. Participants reporting 150 minutes or more of moderate-intensity PA per week were considered to have met the PA guidelines. Multiple logistic regression was used to model the relationships between meeting PA guidelines and health status and preventive health behavior, while controlling for confounding variables. Overall, 53.9% (95% confidence interval [CI], 51.9 to 55.9%) of adults reported meeting the recommended levels of PA. Among adults with good general health, 56.9% (95% CI, 54.7 to 59.1%) reported meeting the recommended levels of PA versus 43.1% (95% CI, 40.9 to 45.3%) who did not. Adults who met the PA guidelines were significantly more likely not to report high cholesterol, diabetes, chronic obstructive pulmonary disease, arthritis, asthma, depression, or overweight. Furthermore, adults meeting the PA guidelines were significantly more likely to report having health insurance, consuming fruits daily, consuming vegetables daily, and not being a current cigarette smoker. In this study, we found meeting the current guidelines for PA to have a protective relationship with both health status and health behavior in adults. Health promotion programs should focus on strategies that help individuals meet the current guidelines of at least 150 minutes per week of moderate-intensity PA.

Minimal effects found across youth physical activity (PA) interventions, and increased attention to circumstances that impede adequate delivery of program components, has highlighted the importance of learning from staff what is needed to foster staff comprehension and engagement for developing, adopting, and successfully implementing PA-based youth interventions. The purpose of this study is to address this knowledge gap by conducting a qualitative assessment of school staff perspectives on the positive aspects and challenges of implementing the 17-week ACT program, an after-school intervention that integrated motivational and behavioral components to promote PA in underserved adolescents. Interviews were conducted with one school staff member from each participating school for all four trial cohorts (N=12). Transcripts were coded by independent coders (r=.84) and content analyses of themes was performed using QSR NVivo. Themes were organized into five meta-themes: (1) Logistics; (2) Essential Elements; (3) Staff and Child Challenges; (4) Staff Comprehension, Value, and Enjoyment; (5) Spill-Over Effects. Findings indicate that staff can be successful at understanding, valuing, and reaching fidelity in implementing climate-based mediation components. The insight gained from this study lays the foundation for understanding the components needed for establishing well-implemented, effective, and generalizable interventions for increasing youth PA.

2014-11-01

This study aimed at investigating whether providing feedback on physical activity (PA) levels to patients with chronic obstructive pulmonary disease (COPD) is feasible and enhances daily PA during pulmonary rehabilitation (PR). Patients with COPD participated in a 12-week PR program. Daily PA was measured using activity monitors on weeks 1, 7, and 12, and feedback was given in the following weeks on the number of steps, time spent in sedentary, light, and moderate-to-vigorous intensity activities, and time spent standing, sitting, and lying. Compliance with PA monitoring was collected. Two focus groups were conducted to obtain patients' perspectives on the use of activity monitors and on the feedback given. Differences in PA data were also assessed. Sixteen patients (65.63 ± 10.57 years; forced expiratory volume in one second (FEV1) 70.31 ± 22.74% predicted) completed the study. From those, only eleven participants used the activity monitors during all monitoring days. Participants identified several problems regarding the use of activity monitors and monitoring duration. Daily steps (p = 0.026) and standing time (p = 0.030) were improved from week 1 to week 7; however, the former declined from week 7 to week 12. Findings suggest that using feedback to improve PA during PR is feasible and results in improved daily steps and standing time on week 7. The subsequent decline suggests that additional strategies may be needed to stimulate/maintain PA improvements. Further research with more robust designs is needed to investigate the impact of feedback on patients' daily PA. © The Author(s) 2014.

Understanding the factors influencing physical activity (PA) in the Asia-Pacific region is critical, given the high prevalence of inactivity in this area. The photovoice technique explores the types of PA and factors influencing PA among adolescents in Kuching, Sarawak. A total of 160 photographs were collected from participants (adolescents, n = 22, mean age = 14.27 ± 0.7 years, and parents, n = 8, mean age = 48 ± 6.8 years). Data analysis used constant comparison methods of a grounded theory. The Analysis Grid for Environments Linked to Obesity was used to categorize PA factors. Study findings were centered on the concept of safety, facilities, parental restriction, friends, cultural traits, media, community cohesiveness, and weather. The central theme was "feeling unsafe" when being outdoors. To promote PA behavior, provision of PA facilities needs to be supported by other programs that build on peer support, crime prevention, and traffic safety, together with other educational campaigns. © 2013 APJPH.

Physical activity in older adults in a combined functional circuit and walking program.

PubMed

Gallagher, Nancy Ambrose; Clarke, Philippa; Carr, Emily

Our study examined the impact of a 16-week functional circuit/walking program on physical activity (PA) in older adults in independent-living facilities. Exploratory goals included examination of associations among self-efficacy, neighborhood and mobility. Participants (N = 13) were female (M = 77.8, SD = 7.44, range = 65-85 years). One third were African-American; the remainder Caucasian; 1/3 used assistive devices. PA increased from 70 min/week (SD = 35.51) at baseline to 81.31 min/week (SD = 34.21) at 16 weeks. PA was associated with self-efficacy for overcoming neighborhood and facility barriers to walking at all measurement points (baseline r = .73, p < .05 and r = .68, p < .05, respectively). At eight weeks, PA was associated with self-efficacy for walking duration (r = .58, p < .05), self-efficacy for individual (r = .66, p < .05), facility (r = .58, p < .05) and neighborhood (r = .70, p < .05) barriers. At sixteen weeks, physical activity was associated with balance confidence (r = .72, p < .05), and self-efficacy for individual (r = .76, p < .05), facility (r = .71, p < .05), and neighborhood (r = .80, p < .01) barriers. Functional circuit/walking interventions can increase PA in older adults. Further examination of self-efficacy, mobility, neighborhoods and PA is needed. Copyright © 2016 Elsevier Inc.

Research examining sustainability of health promotion programs within organizational settings is limited. The Environmental Interventions in Residential Children's Homes (ENRICH) was a structural intervention that trained Wellness Teams (WTs) within residential children's homes (RCH) to target environmental changes that promote physical activity (PA) among residential youth. This study examines the sustainability of PA promoting environments and influences on sustainability within RCHs. A sustainability survey was administered to 14 RCHs 2 years after receiving ENRICH. Variables included sustainability of PA promoting environments, Organizational Influences, perceived organizational and individual benefits, and implementation of PA and general (i.e. Global) wellness activities. Activities reported as sustained and barriers were used descriptively to inform sustainability. Path analyses explained the relationship between sustainability influences and sustainability of PA promoting environments. Sustainability was found in 8 of 14 (57%) RCHs. Sustained activities reflected greater Global versus PA implementation. Global implementation mediated the relationship between Organizational Influences and sustainability, which may have been more easily achieved since Global activities were most likely controlled by WTs and did not require extensive organizational support from RCH administrators. Results highlight the importance of defining and assessing different implementation types when measuring sustainability and influences on sustainability within RCHs organizations. © The Author 2016.

Physical activity promotes health and is important for preventing chronic conditions, such as obesity and cardiovascular disease. Little is known about factors associated with different types of PA among Latina women, particularly Dominicans, who now constitute the fifth largest group of Latinos in the United States. The purpose of this study was to examine whether occupational physical activity, acculturation, familism, and norms held by family and friends are associated with three types of PA: vigorous and moderate leisure-time physical activity (LTPA), and resistance training. Interviews were conducted with 418 Dominican women. We assessed self-reported PA using standardized measures. Data were collected between July 2010 and July 2012 in New York City. Most women reported no vigorous LTPA or resistance training (74.5 and 73.1 %, respectively); about half (52.1 %) reported no moderate LTPA. After adjusting for sociodemographic factors, occupational physical activities were associated with greater LTPA. Acculturation was not associated with any outcome. Positive family norms about exercise were associated with increased LTPA and resistance training. Family norms may play a critical role in PA and should be included in programs to increase PA among Latina women.

It just doesn't speak to me: mid-aged men's reactions to '10,000 Steps a Day'.

2008-04-01

The evaluation of an earlier 10,000 Steps community-based intervention program indicated that men were less likely than women to have used a pedometer or increased their physical activity (PA). This study aimed to explore men's reactions to the 10,000 Steps a Day message, the use of pedometers, and other strategies for increasing PA. Five focus groups were conducted with 39 men aged 45-65 years. Although many were familiar with the 10,000 Steps message, the majority of men did not like it. Pedometers were seen as useful for assessing PA in the short term, but not for ongoing use. Participants were generally aware of PA recommendations. Walking was considered a good option for this age group, but there was varying interest in this type of activity. Weight and stress management were commonly identified benefits of PA. Common barriers to PA were lack of time and motivation, health and weight restrictions, cost, and disinterest. Suggestions of how to promote PA to mid-aged men included workplace initiatives, making PA "fun", and creating opportunities for men to do PA with their family or same-aged peers. PA promotion using the 10,000 Steps message, walking, and pedometers may not appeal to mid-aged men.

The threefold purpose of this study was to (a) determine pubertal stage, racial/ethnic, and socioeconomic status (SES) differences in ratings of interference of barriers to PA; (b) examine relationships between perceived barriers and age, body mass index, recreational screen time, sedentary activity, and PA; and (c) identify girls' top-rated perceived barriers to PA. Girls (N = 509) from eight Midwestern U.S. schools participated. Demographic, pubertal stage, perceived barriers, and recreational screen time data were collected via surveys. Height and weight were measured. Accelerometers measured sedentary activity, moderate-to-vigorous PA (MVPA), and light plus MVPA. Girls of low SES reported greater interference of perceived barriers to PA than those who were not of low SES (1.16 vs. 0.97, p = .01). Girls in early/middle puberty had lower perceived barriers than those in late puberty (1.03 vs. 1.24, p < .001). Girls' perceived barriers were negatively related to MVPA (r = -.10, p = .03) and light plus MVPA (r = -.11, p = .02). Girls' top five perceived barriers included lack of skills, hating to sweat, difficulty finding programs, being tired, and having pain. Innovative interventions, particularly focusing on skill development, are needed to assist girls in overcoming their perceived barriers to PA.

Background: In oncology, physical activity (PA) is recognized to improve psychological and physiological functions. Motivating women with breast cancer to sustain a physically active lifestyle is important for promoting positive health after diagnosis. To review and synthesize what is known about how women with breast cancer experience supervised and unsupervised PA during and after adjuvant treatment. PubMed, PsycINFO, and CINAHL were searched, yielding 994 citations. The final review included 17 articles published between 2004 and 2014 in English. The CASP (Critical Appraisal Skills Programme) instrument was used to appraise quality. Results: Exercise is experienced as a positive element with multiple benefits. However, maintaining a physically active lifestyle during and after chemotherapy is sometimes challenging. Reported benefits of PA include feeling empowered, and improving and reclaiming health. Facilitators to PA comprised exercising with peers and skilled instructors. Barriers included social factors and lack of information. Conclusions: Findings highlight the importance of incorporating PA programs from a patient experience perspective as routine treatment. Health care professionals play a crucial “gateway” role in providing information on implementation and benefits of PA. Providing support and educated advice about how to safely start or continue regular PA to minimize symptoms, reduce morbidity, and increase well-being during or after treatment is vital for women with breast cancer. Implications for Practice: Health care professionals need increased knowledge of the breast cancer patients’ perspectives on facilitators and barriers to PA during and after treatment, in order to provide sufficient support for women to stay physically active during a breast cancer illness.

Obesity and other lifestyle-related chronic diseases impact urban West African women at high rates. Physical activity (PA) can improve these health outcomes but there is little published data on the associated psychosocial predictors in this population. We aimed to explore preliminary associations between perceptions of PA, PA behaviours, and health in a group of Ghanaian women. Non-experimental, cross-sectional case study using a mixed-methods approach. Focus groups and in-depth interviews with a convenience sample of Ghanaian women, fitness trainers and clergy comprised the qualitative phase. A self-administered survey (n=218) comprised the quantitative phase. Constant comparative method, logistic regression, component and factor analyses were used for analysis. Women viewed activities of daily living like housework as PA; rarely utilized organized fitness facilities; understood "rigorous" PA as professional male athleticism; and took interest in socialized PA. Mean age was 49.4 years. Mean body mass index was 30.3 kg/m2. The majority (75.9 %) reported exercising sometimes or often. Half (48.4%) reported a lifestyle-related chronic disease. "Weight loss," "health concerns" and "increased energy," were top motivators for PA. "Can't find the time," "work/family obligations," and "don't have a facility" were top barriers. Presence of hypertension, hypercholesterolemia and prior weight loss correlated with the slimming motivator (adjusted odds ratio 2.59, p=0.008; AOR 3.56, p=0.012; AOR 3.36, p=<0.001). Among those surveyed, PA motivators and barriers were associated with demographics, PA exposure, and health status. Further research on unique PA perceptions, behaviours and health could catalyze health promotion through culturally relevant fitness programming.

The purpose of this study was to describe how patients with chronic pain experience physical activity and exercise (PA&E). This qualitative interview study included 16 women and two men suffering from chronic pain and referred to a multimodal pain rehabilitation program. Semi-structured interviews were conducted and qualitative content analysis was used to analyze the interviews. One main theme emerged: "To overcome obstacles and to seize opportunities to be physically active despite chronic pain." This main theme was abstracted from five themes: "Valuing a life with physical activity," "Physical activity and exercise - before and after pain," "A struggle - difficulties and challenges," "The enabling of physical activity," and "In need of continuous and active support." Although these participants valued PA&E, they seldom achieved desirable levels, and performance of PA&E was undermined by difficulties and failure. The discrepancy between the intention to perform physical activity and the physical activity accomplished could be related to motivation, self-efficacy, and action control. The participants desired high-quality interaction with healthcare providers. The findings can be applied to chronic pain rehabilitation that uses PA&E as treatment.

We prospectively evaluated adolescent organized physical activity (PA) as a factor in adult female bone traits. Annual DXA scans accompanied semiannual records of anthropometry, maturity, and PA for 42 participants in this preliminary analysis (criteria: appropriately timed DXA scans at ~1 year premenarche [predictor] and ~5 years postmenarche [dependent variable]). Regression analysis evaluated total adolescent interscan PA and PA over 3 maturity subphases as predictors of young adult bone outcomes: 1) bone mineral content (BMC), geometry, and strength indices at nondominant distal radius and femoral neck; 2) subhead BMC; 3) lumbar spine BMC. Analyses accounted for baseline gynecological age (years pre- or postmenarche), baseline bone status, adult body size and interscan body size change. Gymnastics training was evaluated as a potentially independent predictor, but did not improve models for any outcomes (p > .07). Premenarcheal bone traits were strong predictors of most adult outcomes (semipartial r2 = .21-0.59, p ≤ .001). Adult 1/3 radius and subhead BMC were predicted by both total PA and PA 1-3 years postmenarche (p < .03). PA 3-5 years postmenarche predicted femoral narrow neck width, endosteal diameter, and buckling ratio (p < .05). Thus, participation in organized physical activity programs throughout middle and high school may reduce lifetime fracture risk in females.

Evidence suggests that most adults with intellectual disability do not participate in sufficient amounts of physical activity (PA). A systematic review of peer-reviewed studies that reported an intervention aiming to improve PA levels of adults with intellectual disability was conducted. Keywords related to intellectual disability and physical activity were used to search relevant databases. Studies were excluded if they did not measure PA as an outcome for adults with intellectual disability, were non-English, and were not peer-reviewed. All relevant studies were included in the review regardless of methodological quality and design. Six articles met the inclusion criteria. These included health education or health promotion programs with PA, nutrition, and weight loss components. The quality of studies included in this review was generally poor. Most studies used a prepost design, sample sizes were small, and measurement tools were used that are not valid and reliable for the population assessed. PA interventions have the potential to improve the health and wellbeing of people with intellectual disability, a vulnerable group who require attention from public health practitioners and researchers. Given the health inequities that exist, public health researchers should target efforts to improve PA levels among this group.

Regular physical activity (PA) benefits older adults. However, frail older adults lack opportunities to be physically active. This pilot study aimed to test and enhance the feasibility of a PA program delivered by home care aides (HCAs) for community-dwelling older adults in a Medicaid-funded home care setting and to generate preliminary efficacy and cost data. HCAs were trained to deliver a brief motivational enhancement and three chair-bound movements to motivate their older clients to do PA daily and to help maintain their independence in the community. Mixed methods were used to evaluate clients' function and health before and after the 4-month intervention. Clients' daily activity function and health outcomes (physical fitness, self-rated health, pain interference, and fear of falling) improved significantly. The program was well-received by clients (N = 54) and their HCAs (N = 46) as indicated by high retention rates among client participants (93%) and remarks provided by clients. Building PA into the everyday care of older adults and the routine work of HCAs is feasible. The intervention has the potential for further implementation and dissemination. © The Author 2017.

Girl Scouting may offer a viable channel for health promotion and obesity prevention programs. This study evaluated the effectiveness of an intervention program delivered through Girl Scout Junior troops that was designed to foster healthful troop meeting environments and increase obesity prevention behaviors at home. Seven Girl Scout troops were randomized to intervention (n = 3, with 34 girls) or standard-care control (n = 4, with 42 girls) conditions. Girls ranged in age from 9 to 13 years (mean 10.5 years). Intervention troop leaders were trained to implement policies promoting physical activity (PA) and healthful eating opportunities at troop meetings, and to implement a curriculum promoting obesity-prevention behaviors at home. The primary outcome variable was child body mass index (BMI) z-score. Secondary outcomes included accelerometer-assessed PA levels in troop meetings, direct observations of snack offerings, time spent in physically active meeting content, and leader encouragement of PA and healthful eating. The intervention was delivered with good fidelity, and intervention troops provided greater opportunities for healthful eating and PA (x2 = 210.8, p < .001), relative to control troops. In troop meetings, intervention troop leaders promoted PA (x2 = 23.46, p < .001) and healthful eating (x2 = 18.14, p < .001) more frequently, and discouraged healthful eating and PA less frequently (x2 = 9.63, p = .002) compared to control troop leaders. Most effects of the intervention on individual-level variables of girls and parents were not significantly different from the control condition, including the primary outcome of child BMI z-score (F1, 5 = 0.42, p = .544), parent BMI (F1, 5 = 1.58, p = .264), and related behavioral variables. The notable exception was for objectively assessed troop PA, wherein girls in intervention troops accumulated significantly less sedentary (x2 = 6.3, p = .011), significantly more moderate (x2 = 8.2, p = .004), and more moderate-to-vigorous physical activity, (x2 = 18.4, p < .001), than girls in control troops. Implementing a health promotion curriculum and supporting policies to provide more healthful environments in Girl Scout troop meetings appears feasible on a broader scale. Additional work is needed to bridge health promotion from such settings to other environments if lasting individual-level behavior change and obesity prevention remain targeted outcomes.

Fundamental movement skills (FMS) proficiency is believed to influence children's physical activity (PA), with those more proficient tending to be more active. Children with cerebral palsy (CP), who represent the largest diagnostic group treated in pediatric rehabilitation, have been found to be less active than typically developing children. This study examined the association of FMS proficiency with PA in a group of children with CP, and compared the data with a group of typically developing children. Five FMS (run, jump, kick, throw, catch) were tested using process- and product-oriented measures, and accelerometers were used to monitor PA over a 7-day period. The results showed that children with CP spent less time in moderate to vigorous physical activity (MVPA), but more time in sedentary behavior than typically developing children. FMS proficiency was negatively associated with sedentary time and positively associated with time spent in MVPA in both groups of children. Process-oriented FMS measures (movement patterns) were found to have a stronger influence on PA in children with CP than in typically developing children. The findings provide evidence that FMS proficiency facilitates activity accrual among children with CP, suggesting that rehabilitation and physical education programs that support FMS development may contribute to PA-related health benefits.

Background Sustainable lifestyle modification strategies are needed to address obesity and cardiovascular risk factors. Intensive, individualised programs have been successful, but are limited by time and resources. We have formulated a group-based lifestyle education program based upon national diet and physical activity (PA) recommendations to manage obesity and cardio-metabolic risk factors. This article describes the content and delivery of this program, with information on compliance and acceptability. Methods Overweight/obese adults (n = 153) with metabolic syndrome were recruited from the community and randomly allocated to intervention (INT) or control (CON). Written copies of Australian national dietary and PA guidelines were provided to all participants. INT took part in a 16-week lifestyle program which provided a curriculum and practical strategies on 1) dietary and PA information based on national guidelines, 2) behavioural self-management tools, 3) food-label reading, supermarkets tour and cooking, 4) exercise sessions, and 5) peer-group support. Compliance was assessed using attendance records and weekly food/PA logs. Participants' motivations, perceived benefits and goals were assessed through facilitated discussion. Program acceptability feedback was collected through structured focus groups. Results Although completion of weekly food/PA records was poor, attendance at information/education sessions (77% overall) and exercise participation (66% overall) was high, and compared with CON, multiple markers of body composition and cardio-metabolic health improved in INT. Participants reported that the most useful program components included food-label reading, cooking sessions, and learning new and different physical exercises, including home-based options. Participants also reported finding self-management techniques helpful, namely problem solving and short-term goal setting. The use of a group setting and supportive 'peer' leaders were found to be supportive. More frequent clinical assessment was suggested for future programs. Conclusion This group-based lifestyle program achieved improvements in body composition and cardio-metabolic and physical fitness similar to individualised interventions which are more resource intensive to deliver. It confirmed that active training in lifestyle modification is more effective than passive provision of guidelines. Such programs should include social support and self-management techniques. Continued clinical follow up may be required for long-term maintenance in individuals attempting lifestyle behaviour change. Program facilitation by peers may help and should be further investigated in a community-based model. PMID:18954466

Learning can be planned by the person him/herself when he or she tries to reflect his/her learning. A study involving prospective science teachers in junior secondary schools was carried out to analyze their ability on Pedagogical Content Knowledge (PCK) in reflective learning after teaching practice. The study was focused especially in creating Pedagogical and Professional Repertoires (PaP-eRs) as part of resource-folios. PaP-eRs as a narrative writing in the learning activities are created by prospective science teachers after lesson plan implementation. Making the narrative writing is intended that prospective science teachers can reflect their learning in teaching. Research subjects are six prospective science teachers who are implementing "Program Pengalaman Lapangan" (PPL) in two junior secondary schools in Bandung, West Java, Indonesia. All of them were assigned by supervisor teachers to teach VII grade students on certain topic "heat and its transfer". Instruments used as a means of collecting data in this study is PaP-eRs. Collected PaP-eRs were then analyzed using PaP-eRs analysis format as instruments for analysis. The result of analyzing PaP-eRs indicates that learning activities, which narrated, involve initial activities, core activities and final activities. However, any activity, which is narrated just superficial as its big line so the narration cannot be, used as reflective learning. It indicates that PCK ability of prospective science teachers in creating narrative writing (PaP-eRs) for reflective learning is still low.

Adequate physical activity is believed to help decrease readmission and improve quality of life for patients with heart failure (HF). The aim of this study was to explore the predictors of physical activity level 1 month after discharge from hospital in Taiwanese patients with HF. A prospective research design was used. Overall, 111 patients with HF from a medical center in Southern Taiwan were recruited. Symptomatic distress, self-efficacy for physical activity, physical activity knowledge, and demographic and disease characteristics of patients with HF were collected at their discharge. One month later, patients' total daily energy expenditure (DEE), DEE for low-intensity physical activities (PA(low) DEE; strictly <3 metabolic equivalents [METs]), DEE for high-intensity physical activities (PA(high) DEE; 3-5 METs), and DEE for intensive-intensity physical activities (PA(intensive) DEE; strictly >5 METs) were collected. The mean total DEE was 8175.85 ± 2595.12 kJ 24 h, of which 19.12% was for PAlow DEE, 7.20% was for PA(high) DEE, and only 1.42% was for PA(intensive) DEE. Body mass index (BMI), age, self-efficacy for instrumental activities of daily living, and educational level were predictors of total DEE of patients with HF 1 month after discharge. Self-efficacy for instrumental activities of daily living, gender, and BMI were predictors of PA(high) DEE. Age, BMI, and symptom distress were predictors of PA(intensive) DEE. Taiwanese patients with HF practiced lower intensity physical activities. Factors related to physical activity of patients with HF in Taiwan were similar to those of Western countries. Nurses should emphasize the importance of physical activity to patients with HF who are male, of older age, with lower educational level, or with lower BMI. Improving self-efficacy for instrumental activities and decreasing symptom distress should be incorporated into discharge planning programs for patients with HF.

Little is known about lifestyle choices and preventive healthcare-seeking behaviors during the transition from medical school graduation to residency training, a period characterized by increased rates of stress and lack of free time due to demanding working conditions. All of these issues are likely to affect physical activity (PA) level. This study explored the evolution of PA and other lifestyle behaviors during this transition. A cross-sectional study and a cohort study were conducted with medical students (2010) and physicians before and after the first year of residency (2013 and 2014). A self-administered questionnaire assessed PA, health and lifestyle behaviors. From a sample of 420 medical students and 478 residents, 74% comply with current PA guidelines. PA decreased by 16% during residency. Low levels of PA were found among (i) females and in respondents who reported (ii) poor self-perceived health and (iii) unhealthy body weight (P < .05). Low PA level was also significantly associated with poor mental health in first-year residents. The transition has a negative effect on physicians' PA level that may affect physicians' own health and patient care. Medical programs should encourage residents to engage in PA to assure physicians' personal and mental health.

The Government of Canada implemented a Children's Fitness Tax Credit (CFTC) in 2007 which allows a non-refundable tax credit of up to $500 to register a child in an eligible physical activity (PA) program. The purposes of this study were to assess whether the awareness, uptake, and perceived effectiveness of this tax credit varied by household income among Canadian parents. An internet-based panel survey was conducted in March 2009 with a representative sample of 2135 Canadians. Of those, parents with children aged 2 to 18 years of age (n = 1004) were asked if their child was involved in organized PA programs (including dance and sports), the associated costs to register their child in these programs, awareness of the CFTC, if they had claimed the CFTC for the tax year 2007, and whether they planned to claim it in the upcoming year. Parents were also asked if they believed the CFTC has lead to their child being more involved in PA programs. Among parents, 54.4% stated their child was in organized PA and 55.5% were aware of the CFTC. Parents in the lowest income quartile were significantly less aware and less likely to claim the CFTC than other income groups. Among parents who had claimed the CFTC, few (15.6%) believed it had increased their child's participation in PA programs. More than half of Canadian parents with children have claimed the CFTC. However, the tax credit appears to benefit the wealthier families in Canada.

There is a scarcity of information about the proportion of the adult Saudi population that meet the recommended guidelines of physical activity (PA) to reduce cancer risk. Moreover, their awareness about the role of PA in cancer prevention is unclear. This cross-sectional study aimed at estimating the proportion of adult Saudis meeting the PA guidelines, specifically those recommended by American Cancer Society (ACS) for cancer prevention, and to assess the public awareness about the role of PA in cancer prevention. Using a multistage sampling method, 2,127 adult Saudis of both genders were recruited from 6 urban and 4 rural primary health care centers in Al Hassa, Saudi Arabia. Participants were personally interviewed to gather information about their sociodemographic characteristics, searching activity about PA and cancer, and the time spent in leisure time PA (moderate and vigorous)/week using the Global Physical Activity Questionnaire with show cards. Finally, items about the role of PA in cancer risk reduction were inquired. Of the included participants, 11.6% met the recommendations for cancer prevention (≥ 45 minutes of moderate-vigorous PA activity/≥ 5 days/week or 225 minutes/week). Multivariate regression showed that being male (AOR=1.49, CI=1.09-2.06), <20 years of age (AOR=3.11, CI=2.03-4.76), and unemployed (AOR=2.22, CI=1.57-3.18) were significant predictors for meeting PA recommendations for cancer prevention. Only 11.4% of the sample indicated correctly the frequency and duration of PA required for an average adult to be physically active and while >70% of them indicated the role of PA in prevention of hypertension, coronary heart disease and lowering elevated blood cholesterol, only 18.6% and 21.7% correctly mentioned the role of PA in reducing colon and breast cancer risk, respectively. Poor knowledge was found among those with less than college education and aged ≥ 50 years. The level of knowledge was significantly positively correlated with total leisure time PA of the participants. A minority of adult Saudis in Al Hassa was aware about the role of PA in cancer prevention and engaged in sufficient LTPA for cancer risk reduction benefits, highlighting the need for public health actions to include policies and programs that address factors deterring their participation in LTPA and increasing their awareness with remedies to manage the prevalent misconceptions.

Since physical activity (PA) is capable of improving both the quality of life and the prognosis for individuals with mental and behavioral disorders (MBD), the main purpose of this study was to analyze the PA patterns in individuals with MBD frequenting a Psychosocial Care Center (PCC) in the city of Pelotas. The target population of this descriptive study consisted of individuals attended in any of the PCCs of Pelotas. The sample was selected from six PCCs and comprised 85 patients and their relatives. The mean age of the sample was 40.9 years (standard deviation 13.8). It was found that, in comparison with the general population, these individuals had a lower socioeconomic level and less schooling. The prevalence of leisure-time physical activity was low. In addition, women tended to dedicate the greater part of their time to household activities. Men participated more in the PA offered by the PCC than women. Therefore, incorporation of PA in PCC seems to be a feasible initiative for supporting the treatment of these patients and would offer a unique opportunity for the patients to engage in supervised and structured PA programs.

Regular physical activity (PA) and the avoidance of prolonged sitting are essential for children's healthy growth, and for the physical and mental wellbeing of both children and adults. In the context of exercise, music may promote behavioral change through increased exercise adherence and participation. The purpose of this study was to determine whether a movement-to-music video program could reduce sedentary behavior (SB) and increase PA in mother-child pairs in the home environment. A randomized controlled trial was conducted in the Pirkanmaa region, Finland, in 2014-2016. The participants consisted of 228 mother-child pairs (child age 5-7 years). The primary outcomes of interest were tri-axial accelerometer-derived SB and PA, which were measured in weeks one (baseline), two, and eight in both the intervention and control groups. Further, the mothers and children in the intervention group used a movement-to-music video program from the beginning of week two to the end of week eight. Secondary outcomes included self-reported screen time. The statistical methods employed comprised an intention-to-treat and linear mixed effects model design. No statistically significant differences between groups were found in primary or secondary outcomes. Among the children in the control group, light PA decreased significantly over time and screen time increased from 89 (standard deviation, SD 37) to 99 (SD 41) min/d. Among mothers and children in the intervention group, no statistical differences were found. In supplementary analysis, the children who stayed at home instead of attending daycare/preschool had on average 25 (95% confidence interval, CI 19-30) min/d more sedentary time and 11 (95% CI 8-14) min/d less moderate-to-vigorous PA than those who were at daycare/preschool. The higher body mass index of mothers was related with 5 (95% CI 2-7) min/d more sedentary time and 1 (95% CI 0-2) min/d less moderate-to-vigorous PA. The movement-to-music video program did not change the objectively measured SB or PA of the mother-child pairs. However, mothers and children seemed to be more sedentary at home, and therefore interventions for decreasing SB and increasing PA should be targeted in the home environment.

A randomized controlled trial was conducted in the Pirkanmaa region, Finland, in 2014–2016. The participants consisted of 228 mother-child pairs (child age 5–7 years). The primary outcomes of interest were tri-axial accelerometer-derived SB and PA, which were measured in weeks one (baseline), two, and eight in both the intervention and control groups. Further, the mothers and children in the intervention group used a movement-to-music video program from the beginning of week two to the end of week eight. Secondary outcomes included self-reported screen time. The statistical methods employed comprised an intention-to-treat and linear mixed effects model design. No statistically significant differences between groups were found in primary or secondary outcomes. Among the children in the control group, light PA decreased significantly over time and screen time increased from 89 (standard deviation, SD 37) to 99 (SD 41) min/d. Among mothers and children in the intervention group, no statistical differences were found. In supplementary analysis, the children who stayed at home instead of attending daycare/preschool had on average 25 (95% confidence interval, CI 19–30) min/d more sedentary time and 11 (95% CI 8–14) min/d less moderate-to-vigorous PA than those who were at daycare/preschool. The higher body mass index of mothers was related with 5 (95% CI 2–7) min/d more sedentary time and 1 (95% CI 0–2) min/d less moderate-to-vigorous PA. The movement-to-music video program did not change the objectively measured SB or PA of the mother-child pairs. However, mothers and children seemed to be more sedentary at home, and therefore interventions for decreasing SB and increasing PA should be targeted in the home environment. PMID:28859091

BackgroundWe intended to evaluate the effects of physical activity (PA) programs on renal function in obese boys.MethodsThirty-nine boys participated in one of the following three groups: soccer (SG, n=13), traditional PA (AG, n=13), and sedentary control (CG, n=13). SG and AG were involved in 6-month PA programs, involving three sessions/week for 60-90 min. Anthropometric measurements, body composition, creatinine and cystatin C plasmatic levels, and estimated glomerular filtration rate (eGFR) were evaluated.ResultsAt baseline (n=39), age and lean mass index (LMI) were positively correlated with creatinine levels. After 6 months, both intervention groups decreased the BMI z-score and waist circumference, while the CG increased the body fat percentage (BFP). LMI increased in all the groups. SG presented a small increment in plasma creatinine and a decrease in the eGFR values, using the Schwartz formula. Concerning the cystatin C levels and eGFR values using Filler (cystatin C-based) or Combined Zappitelli (creatinine/cystatin C-based) formulas, no significant changes were observed in any group.ConclusionThe combined Zappitelli formula showed no significant impact of PA on eGFR in obese boys. Although plasma creatinine is significantly influenced by lean body mass, cystatin C is likely to be a more accurate marker of renal function in this population.

Socio-demographic, medical and social-cognitive correlates of physical activity behavior among older adults (45–70 years): a cross-sectional study

PubMed Central

2014-01-01

Background Present study aimed to identify socio-demographic, medical and social-cognitive correlates of physical activity among Dutch older individuals. Methods A systematic random sample of 2,568 Dutch participants aged 45–70 years filled out the validated modified Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire on physical activity. Socio-demographic and social-cognitive correlates were measured with validated instruments; medical correlates were checked by a general practitioner. The study had a cross-sectional design and the data collection ran from March 2005 until August 2006. Linear regression analyses were conducted to identify correlates of PA. We separated the findings for men from those for women to explore potential gender-specific associations. Results Being female, living in North Limburg or North-Brabant, having a higher educational level, a higher perceived behavioral control, more knowledge about PA advantages, a stronger habitual PA behavior, having more action plans and a stronger intention to engage in PA were significantly associated with higher PA levels. Being older, being a smoker, having a higher body mass index (BMI), having a paid job, observing others being physically active and overestimating one's PA level were associated with being less physically active. Socio-demographic and medical correlates significantly explained 20% of the variance of PA behavior while social-cognitive correlates as attitude explained an additional 4% and intention together with actual control explained another 1% of the variance of PA behavior. Conclusion There may be stable individual differences that influence PA in view of the fact that several socio-demographic and medical factors were not completely mediated by the socio-cognitive factors. The current study may help to focus PA interventions for individuals aged 45–70 years on influential socio-demographic, medical and social-cognitive correlates. Physical activity was significantly associated with age, gender, education, BMI, work situation, region of residence, smoking, awareness, advantages, descriptive norm, perceived behavioral control, habit, action plans and intention.

Educating for Civic Engagement: Public Achievement as a Case Study

NASA Astrophysics Data System (ADS)

Costello, Bernadette Christine

Over the last four decades there is evidence that citizens are less civically engaged, have less trust in each other and governmental institutions, and are less prepared to participate in deliberative and civic processes. This research studies the importance of acquiring deliberative and civic skills and behaviors as an integral part of civic engagement and developing educational and learning strategies to impart those skills and behaviors in an educational environment. This research uses a civic action program called Public Achievement (PA) as a case study to investigate if participating in a civic and deliberative focused program enables participants to continue to use the skills and behaviors learned in PA in non-PA activities. The research study was focused by a literature review of philosophical frameworks, educational history in the United States, and educational theory. The literature review and examples of learning civic skills and behaviors in secondary and higher educational institutions are examined to frame the analysis of PA. Based on the literature review and the design of PA, constructs and a survey instrument were developed to test the hypothesis that students who participate in PA will be more likely to exhibit civic skills and behaviors than students who did not participate in PA. The research was conducted with two schools in rural Missouri, two schools in Minneapolis, Minnesota, and two schools in St. Paul, Minnesota. The study results show that students who participated in PA were not more likely to exhibit civic skills and behaviors, and in many cases, non-PA students exhibited civic skills and behaviors more often. The findings revealed that there are programmatic, organizational, and societal barriers that may impede the effectiveness of PA. The findings suggest that implementation of civic engagement programs may be more effective when the effort is supported and reinforced by and across all parts of the organization, organizational readiness work is completed prior to implementation, and civic skills and behaviors are part of institutional and student assessment processes. Additional research is suggested to develop an assessment tool to measure an organization's readiness to implement civic engagement programs and educational assessments to measure the cognitive and affective acquisition of civic skills and behaviors.

Background Inadequate physical activity (PA) contributes to the high prevalence of overweight and obesity among U.S. adolescent girls. Barriers preventing adolescent girls from meeting PA guidelines have not been thoroughly examined. Objectives The threefold purpose of this study was to: (a) determine pubertal stage, racial/ethnic, and socioeconomic status (SES) differences in ratings of interference of barriers to PA; (b) examine relationships between perceived barriers and age, body mass index (BMI), recreational screen time, sedentary activity, and PA; and (c) identify girls’ top-rated perceived barriers to PA. Methods Girls (N = 509) from eight Midwestern U.S. schools participated. Demographic, pubertal stage, perceived barriers, and recreational screen time data were collected via surveys. Height and weight were measured. Accelerometers measured sedentary activity, moderate-to-vigorous physical activity (MVPA), and light plus MVPA. Results Girls of low SES reported greater interference of perceived barriers to PA than those who were not of low SES (1.16 vs. 0.97, p = .01). Girls in early/middle puberty had lower perceived barriers than those in late puberty (1.03 vs. 1.24, p < .001). Girls’ perceived barriers were negatively related to MVPA (r = −.10, p = .03) and light plus MVPA (r = −.11, p = .02). Girls’ top five perceived barriers included lack of skills, hating to sweat, difficulty finding programs, being tired, and having pain. Discussion Innovative interventions, particularly focusing on skill development, are needed to assist girls in overcoming their perceived barriers to PA. PMID:26325276

Physical activity (PA) provides multiple benefits to children with visual impairments (VI) and their families. However, the empirical literature base is underdeveloped on how family PA experiences impact participation for children with VI. The purpose of this study was two-fold; that is: (a) to explore why families with children with VI seek out and participate in PA, and (b) to describe the strategies and supports needed by families of children with VI to improve PA participation. The research method was descriptive-qualitative positioned in the theoretical framework of the theory of planned behavior. Participants were parents of children with VI (n = 10) who took part in one-on-one semi-structured telephone interviews. Interview recordings were transcribed and analyzed using a thematic line-by-line analysis. Three salient, recurrent, and interrelated themes emerged from the data analyses. These themes were: (a) committed, (b) challenged, and (c) access. Findings revealed that parents valued PA, but they lacked the skills to teach and advocate for their children regarding PA. As a consequence, parents voiced the need for a support system that would allow their families to be more physically active. Implications for Rehabilitation Results of this study demonstrated that parents valued physical activity, but they lacked the skills necessary to confidently engage their children in physical activity. Physical activity interventions are needed to enhance the quality of life of children with visual impairments and their families. Physical activity programs and interventions are most likely to enhance intentions to engage in physical activity among children with visual impairments and their parents. Results demonstrated that parents of children with visual impairments were interested to work side-by-side with physical activity professionals to enhance recreational physical activity opportunities available to their children.

Reduced physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality (e.g. exacerbations) and eventually leads to disability, depression, and social and physical isolation. Measuring PA in this population is important to accurately characterize COPD and to help clinicians during a baseline evaluation and patient follow-up. Also, it may help increase adherence to PA programs. There are reliable objective and subjective methods available to measure PA. Recently, several new monitors have been developed that have improved accuracy of such measurements. Because these devices provide real-time feedback, they may help to improve participant self-motivation strategies and reinforce daily lifestyle modifications, one of the main goals in COPD management. This review focuses on describing available instruments to measure PA, specifically in patients with COPD. The reliability, validity, advantages, limitations, and clinical applications of questionnaires, pedometers, and accelerometers are discussed. Finally, based on current published literature, we propose recommendations about which methods may be most useful in different research or clinical settings. PMID:28848818

Physical activity (PA) may counteract depressive symptoms in nursing home (NH) residents considering biological, psychological, and person-environment transactional pathways. Empirical results, however, have remained inconsistent. Addressing potential shortcomings of previous research, we examined the effect of a whole-ecology PA intervention program on NH residents' depressive symptoms using generalized linear mixed-models (GLMMs). We used longitudinal data from residents of two German NHs who were included without any pre-selection regarding physical and mental functioning (n = 163, M age = 83.1, 53-100 years; 72% female) and assessed on four occasions each three months apart. Residents willing to participate received a 12-week PA training program. Afterwards, the training was implemented in weekly activity schedules by NH staff. We ran GLMMs to account for the highly skewed depressive symptoms outcome measure (12-item Geriatric Depression Scale-Residential) by using gamma distribution. Exercising (n = 78) and non-exercising residents (n = 85) showed a comparable level of depressive symptoms at pretest. For exercising residents, depressive symptoms stabilized between pre-, posttest, and at follow-up, whereas an increase was observed for non-exercising residents. The intervention group's stabilization in depressive symptoms was maintained at follow-up, but increased further for non-exercising residents. Implementing an innovative PA intervention appears to be a promising approach to prevent the increase of NH residents' depressive symptoms. At the data-analytical level, GLMMs seem to be a promising tool for intervention research at large, because all longitudinally available data points and non-normality of outcome data can be considered.

Few breast cancer survivors (BCS) engage in sufficient physical activity (PA) to gain physical and mental health benefits. This may be due to a lack of appropriate PA information and support. While key messengers of PA information could be oncology clinicians, many do not consistently counsel their patients on PA. To examine factors affecting PA counseling in clinicians and inform future strategies. Focus groups were conducted with clinicians (N = 27) at four cancer hospitals to better understand factors that affect PA counseling. Focus group discussions were transcribed verbatim and analyzed using inductive thematic analysis. Clinicians perceived a lack of training and knowledge related to PA and BCS. Clinicians also discussed being unsure of when to integrate PA counseling into different phases of survivorship. Similarly, clinicians experienced barriers from hospital administration to maintain patient flow in-clinic, which decreased opportunities for PA counseling. Additionally, lack of awareness of community-based programs within large areas served by hospitals also decreased clinicians' self-efficacy for counseling. In order to facilitate PA counseling, clinicians wanted resources that promote patient-managed PA, available on multiple platforms (e.g., printed and online). Continued education, highlighting recent research and effective implementation of PA, was noted as an important facilitator. Researchers are encouraged to develop research agendas and test educational strategies that are integrated into current practice, empirically test barriers that developed from this study with a larger, representative sample to determine salient barriers and develop PA counseling strategies that are clinician-initiated but not dependent on clinicians.

Introduction: This study aims to assess the associated factors of physical inactivity among Iranian children and adolescents at national level. The second objective is to assess the relationship of physical inactivity with anthropometric measures. Methods: Along with a national surveillance program, this survey on weight disorders was conducted among a nationally-representative sample of Iranian children and adolescents, aged 6-18 years. Students were selected by multi-stage cluster sampling from rural and urban areas of 30 provinces of Iran. The Physical Activity Questionnaire for Adolescents (PAQ-A) was used to assess physical activity (PA). Using PAQ-A instrument, PA of past week categorized as; low PA level, that included those who scored between 1 to 1.9 on the PAQ-A instrument and high PA level that included participants with estimated scores between 2-5 PAQ-A. Results: Participants were 23183 school students (50.8% boys) with a mean age of 12.55 ± 3.3 years, without significant difference in terms of gender. Totally, 23.48% of participants (13.84% of boys and 33.42% of girls) were physically inactive. In multivariate logistic regression model, with increased age in children and adolescence, the odds of a physically inactivity increased (OR: 1.08; 95% CI: 1.07-1.10). The odds of prevalence of both obesity and underweight were high in children and adolescents with low PA. There was a decreasing trend in PA in higher school grades. Conclusion: We found a considerably high prevalence of physical inactivity in Iranian children and adolescents, with higher rates among girls and older ages. However, we did not find correlation between PA and socioeconomic status (SES). Because of the positive relationship between PA and ST, future studies should consider the complex interaction of these two items. Multidisciplinary policies should be considered in increasing PA programs among children and adolescents.

Postpartum women's recovery from birth can be assisted through increased physical activity (PA). However, women face substantial barriers to participating in exercise and require support to enable them to benefit from increased PA. This study sought to explore women's beliefs about and experiences of PA and exercise during the 6 weeks to 12 months postpartum period. A cohort of 14 postpartum women from a survey study of the barriers and enablers to exercise participation agreed to take part in interview sessions to provide an in-depth understanding of the women's perceptions of the postpartum period and their physical activity during this time. Findings are presented with reference to the social ecological framework and indicate postpartum women face substantial personal and environmental barriers to PA and exercise participation: fatigue, a lack of motivation and confidence, substantial time constraints, lack of access to affordable and appropriate activities and poor access to public transport. In contrast, enablers such as possessing greater social support, in particular partner support, improved PA and exercise participation. The findings encourage facilitation of exercise through mothers' groups, mothers' exercise clubs or postnatal classes suggesting behavioral and social change is needed. Interaction between individuals, community, organizations and policy makers is required. In addition, the provision of specifically tailored and appropriate exercise programs could potentially enable increased PA in postpartum women, thereby improving their health.

The purpose of this study was to use the social cognitive theory (SCT) constructs self-efficacy, outcome expectations, and self-regulation to better understand associations of physical activity (PA) behaviors among dialysis patients after controlling for demographic and health-related factors. This study was cross-sectional in design. Participants (N = 115; mean age = 61.51 years, SD = 14.01) completed self-report questionnaires during a regularly scheduled dialysis treatment session. Bivariate and hierarchical linear regression analyses were conducted to examine relationships among SCT constructs and PA. Significant relationships between PA and self-efficacy (r = .336), self-regulation (r = .280), and outcome expectations (r = .265) were detected among people on dialysis in bivariate analyses. Hierarchical linear regression revealed significant increases in variance explained for the addition of self-efficacy, self-regulation, and covariates (p < .01). Younger age, self-efficacy, and self-regulation were associated (p < .10) with greater participation in physical activity in the final model (R² = .272). Conclusion/Implication: This research supports the use of SCT in understanding PA among people undergoing dialysis treatment. The findings of this study can help health educators and health care practitioners better understand PA and how to promote it among this population. Future research should further investigate which activities dialysis patients participate in across the life span of their disease. Future PA programs should focus on increasing a patient's self-efficacy and self-regulation.

We prospectively evaluated adolescent organized physical activity (PA) as a factor in adult female bone traits. Annual DXA scans accompanied semi-annual records of anthropometry, maturity and PA for 42 participants in this preliminary analysis (criteria: appropriately timed DXA scans at ~1 year pre-menarche [predictor] and ~5 years post-menarche [dependent variable]). Regression analysis evaluated total adolescent inter-scan PA and PA over 3 maturity sub-phases as predictors of young adult bone outcomes: 1) bone mineral content (BMC), geometry and strength indices at non-dominant distal radius and femoral neck; 2) sub-head BMC; 3) lumbar spine BMC. Analyses accounted for baseline gynecological age (years pre- or post-menarche), baseline bone status, adult body size and inter-scan body size change. Gymnastics training was evaluated as a potentially independent predictor, but did not improve models for any outcomes (p<0.07). Pre-menarcheal bone traits were strong predictors of most adult outcomes (semi-partial r2 = 0.21-0.59, p≤0.001). Adult 1/3 radius and sub-head BMC were predicted by both total PA and PA 1-3 years post-menarche (p<0.03). PA 3-5 years post-menarche predicted femoral narrow neck width, endosteal diameter and buckling ratio (p<0.05). Thus, participation in organized physical activity programs throughout middle and high school may reduce lifetime fracture risk in females. PMID:25386845

Physical activity (PA) levels are a key performance indicator for policy documents in Ireland. The first Ireland Report Card on Physical Activity in Children and Youth aims to set a robust baseline for future surveillance of indicators related to PA in children and youth. Data collected between 2003-2010 on more than 35,000 7- to 18-year-old children and youth were used and graded using a standardized grading system for 10 indicators. Grades assigned for the indicators were as follows: overall physical activity levels, D-; sedentary behavior (TV viewing), C-; organized sport participation, C-: physical education, D-; active play, inconclusive (INC); active transportation, D; school, C-, community and the built environment, B; family, INC; and government, INC. PA recommendations exist in Ireland but this Report Card has shown that participation is still low. A number of promising policies, programs and services are in place but these require thorough evaluation and adequate resourcing. Agreement and implementation of a common framework for the systematic surveillance of indictors related to PA of children and youth is necessary to monitor change over time and ensure the impact of promising work is captured.

Objectives The use of brief screening tools to identify inactive patients is essential to improve the efficiency of primary care-based physical activity (PA) programs. However, the current employment of short PA questionnaires within the Spanish primary care pathway is unclear. This study evaluated the validity of the Spanish version of a Brief Physical Activity Assessment Tool (SBPAAT). Methods A validation study was carried out within the EVIDENT project. A convenience sample of patients (n = 1,184; age 58.9±13.7 years; 60.5% female) completed the SBPAAT and the 7-day Physical Activity Recall (7DPAR) and, in addition, wore an accelerometer (ActiGraph GT3X) for seven consecutive days. Validity was evaluated by measuring agreement, Kappa correlation coefficients, sensitivity and specificity in achieving current PA recommendations with the 7DPAR. Pearson correlation coefficients with the number of daily minutes engaged in moderate and vigorous intensity PA according to the accelerometer were also assessed. Comparison with accelerometer counts, daily minutes engaged in sedentary, light, moderate, and vigorous intensity PA, total daily kilocalories, and total PA and leisure time expenditure (METs-hour-week) between the sufficiently and insufficiently active groups identified by SBPAAT were reported. Results The SBPAAT identified 41.3% sufficiently active (n = 489) and 58.7% insufficiently active (n = 695) patients; it showed moderate validity (k = 0.454, 95% CI: 0.402–0.505) and a specificity and sensitivity of 74.3% and 74.6%, respectively. Validity was fair for identifying daily minutes engaged in moderate (r = 0.215, 95% CI:0.156 to 0.272) and vigorous PA (r = 0.282, 95% CI:0.165 to 0.391). Insufficiently active patients according to the SBPAAT significantly reported fewer counts/minute (-22%), fewer minutes/day of moderate (-11.38) and vigorous PA (-2.69), spent fewer total kilocalories/day (-753), and reported a lower energy cost (METs-hour-week) of physical activities globally (-26.82) and during leisure time (-19.62). Conclusions The SBPAAT is a valid tool to identify Spanish-speaking patients who are insufficiently active to achieve health benefits. PMID:26379036

Regular physical activity is an important lifestyle behavior for preventing or reducing the burden of osteoporosis, and for promoting optimal bone health. This report evaluates the effect of an osteoporosis education program on knowledge, self-efficacy, and initiation and/maintenance of physical activity (PA) in older African Americans. African American adults 50 years and older (n=130) were randomly assigned to either experimental (EG) or control (CG) groups. Immediately following baseline assessment EG was offered six-weekly education sessions, using the Expanded Heath Belief Model and the CG offered same after the intervention. Main outcome measures were knowledge and self-efficacy regarding osteoporosis and engagement in PA. One hundred and ten (59=EG, 51=CG) participants completed all assessments. Overall, significantly higher (p<.01) mean self-efficacy and knowledge scores were observed in the EG than in the CG. Physical activity scores were positively related to self-efficacy but not knowledge scores. Self-efficacy is important in increasing PA in older African Americans, and emphasis on culturally appropriate strategies may improve PA and reduce the risk of osteoporotic fracture.

Background Physical activity (PA) is an important component of weight loss programs and may be encouraged for severely obese patients undergoing bariatric surgery. However, few studies have determined the amount and intensity of activities undertaken preoperatively by bariatric surgery patients using objective measures. Methods Using RT3 tri-axial accelerometers, this study compared 38 bariatric surgery candidates and 20 normal-weight controls on: 1) activity counts/hour; 2) minutes/day spent in moderate-to-vigorous intensity PA (MVPA) and vigorous intensity PA (VPA); and 3) level of compliance with national recommendations to accumulate 150 minutes/week of MVPA in bouts ≥ 10 minutes. Results Surgery candidates, compared to controls, recorded significantly (Ps < 0.01) fewer activity counts/hour (13799 ± 3758 vs 19462 ± 4259) and spent fewer minutes/day engaged in MVPA (26.4 ± 23.0 vs 52.4 ± 24.7) and VPA (1.2 ± 3.4 vs 11.8 ± 9.0). More than two-thirds (68%) of surgery candidates versus 13% of NW did not accumulate any MVPA in bouts ≥ 10 minutes and only 4.5% of Ob met the weekly MVPA recommendation compared to 40% of NW. Conclusion Bariatric surgery candidates have low PA levels and rarely engage in PA bouts of sufficient duration and intensity to maintain and improve health. Additional research is needed to determine how best to increase PA in bariatric surgery candidates. PMID:19837009

Physical education (PE) programs aim to promote physical activity (PA) and reach most school-aged youth. However, PA levels within PE lessons are often low. In this cluster-randomized controlled trial, we examined the effects of three self-determination theory-based motivational strategies on PA and sedentary behavior, as well as their hypothesized antecedents during PE lessons. Data were collected in Sydney, Australia (October-December 2011). After baseline testing, teachers (n=16) and their classes (n=288 students; M=13.6 years, 50.4% male) were randomly assigned to one of four teaching strategy conditions: (1) explaining relevance; (2) providing choice; (3) complete free choice; or (4) usual practice. Teachers then delivered the assigned strategy. Primary outcomes were accelerometer-assessed PA and student motivation during lessons. Secondary outcomes included sedentary behavior, perceptions of teachers' support and psychological needs satisfaction. The 'free choice' intervention increased PA (p<.05). 'Providing choice' and 'free choice' interventions decreased sedentary behavior (p<.05). The interventions did not influence motivation, but students' autonomy increased during both choice-based interventions (p<.05). Promoting choice can produce short-term increases in PA and decreases in sedentary behavior, as well as increased perceived autonomy during PE lessons. © 2013.

Various organizations have suggested that physical education (PE) should play a central role in increasing adolescents' physical activity (PA) levels. The purpose of this study was to examine relationships between students' self-determined motivation and their PA behavior during a structured PE lesson led by their teacher and a free-choice period in which they were not required to be active. 528 Hong Kong students (mean age=15.78 years) participated in this study in April and May 2007. Situational Motivation Scale scores were used to form high and low self-determined motivation groups. Students wore a pedometer during a 20-minute structured basketball lesson and a 20-minute free choice period, during which they did not receive instruction. ANOVA revealed that self-determined motivation and PE class environments which provided students opportunities to make choices were related to greater PA. Furthermore, the difference in PA between the high and low self-determined groups was greater in the free-choice condition than the structured lesson, suggesting that self-determined motivation is especially important when students are not supervised. Findings indicated that promoting self-determined motivation may be an effective means of ensuring that PE programs are able to increase PA levels, foster self-initiated PA behaviors, and enhance adolescents' health.

This study determined facilitators and barriers to human papillomavirus (HPV) vaccination perceived by providers of healthcare in the federally funded Pennsylvania Vaccines for Children (PA VFC) program. The cross-sectional study gathered descriptive data through a survey research design. Providers of healthcare were recruited through an email containing a link to an 18-question online survey. The survey was divided into four main sections which assessed the perceived facilitators and barriers to HPV vaccination of PA VFC program-eligibles. Survey respondents represented 65 of 66 Pennsylvania counties covered by the PA VFC Program. The study recruited 772 PA VFC participating healthcare facilities for a response rate of 52%. Ninety eight percent of the responding facilities reported that they offered the HPV vaccine. The most common barriers to vaccine administration were the parental belief that HPV vaccination is associated with sexual activity and parent/patient refusal of the HPV vaccination which together accounted for (44%) of responses. The majority of respondents (75.6%) indicated counseling parents and adolescents on the benefits of HPV vaccination was a very important factor in HPV vaccination uptake. Healthcare provider facility based training (32%) and web-based training for healthcare providers (22%) were the most recommended avenues for HPV training. The most common barrier to HPV vaccination was identified as the parental misconception that HPV vaccination is associated with sexual activity. Providers believed that the best way to increase HPV vaccination is through counseling parents and adolescents on the benefits of HPV vaccination and to correct misconceptions and change attitudes. Providers are desirous of receiving HPV web-based or workplace training.

Exercise-referral scheme to promote physical activity among hypertensive patients: design of a cluster randomized trial in the Primary Health Care Units of Mexico’s Social Security System

PubMed Central

2014-01-01

Background Although the benefits of physical activity (PA) on to prevent and manage non-communicable diseases are well known, strategies to help increase the levels of PA among different populations are limited. Exercise-referral schemes have emerged as one effective approach to promote PA; however, there is uncertainty about the feasibility and effectiveness of these schemes in settings outside high-income countries. This study will examine the effectiveness of a scheme to refer hypertensive patients identified in Primary Health Care facilities (PHCU) of the Mexican social security institution to a group PA program offered in the same institution. Methods and design We will describe the methods of a cluster randomized trial study designed to evaluate the effectiveness of an exercise referral scheme to increasing physical activity in hypertensive patients compared to a non-referral scheme. Four PHCU were selected for the study; the PHCU will take part as the unit of randomization and sedentary hypertensive patients as the unit of assessment. 2 PHCU of control group (GC) will provide information to hypertensive patients about physical activity benefits and ways to increase it safely. 2 PHCU of intervention group (IG) will refer patients to sports facilities at the same institution, to follow a group-based PA program developed to increase the PA levels with a designed based on the Transtheoretical Model and Social Cognitive Theory. To evaluate the effects of the intervention as well as short-term maintenance of the intervention’s effects, PA will be assessed at baseline, at 24 and 32 weeks of follow-up. The main outcome will be the difference before and after intervention in the percentage of participants meeting recommended levels of PA between and within intervention and control groups. PA will be measured through self-report and with objective measure by accelerometer. Discussion This study will allow us to evaluate a multidisciplinary effort to link the primary care and community-based areas of the same health care system. Our findings will provide important information about the feasibility and effectiveness of an exercise-referral scheme and will be useful for decision-making about the implementation of strategies for increasing PA among hypertensive and other clinical populations in Mexico and Latin America.

Excellence in physician assistant training through faculty development.

PubMed

Glicken, Anita Duhl

2008-11-01

Once again, experts predict a shortage of health care providers by 2020. The physician assistant (PA) profession was created in the 1960s to address a similar need. Currently, there are 141 accredited PA training programs in the United States, 75 of them established in the 10 years between 1993 and 2002. Historically, PA education and practice models have been responsive to the ever-changing landscape of health care. It may be the profession's flexibility and adaptability that has enabled it to survive and flourish in a competitive service environment. The growth of new PA programs mandates a need for continuing faculty development, as increasing numbers of educators hail primarily from clinical practice and come equipped with minimal teaching experience. PA faculty development addresses these new recruits' needs to develop model curricula, implement new courses, and enhance instruction-all with the goal of improving both access to and quality of health care.The author describes the impact of Health Resources and Service Administration Title VII, Section 747 (Title VII) contracts in addressing this need. Title VII-funded PA education projects, considered innovative at the time of implementation, included both faculty development workshops that promoted active learning of basic teaching and administrative skills and new curricula designed to enhance faculty teaching in genomics and practice management. These projects and others resulted in enduring professional resources that have not only strengthened the PA community but also enjoyed broad applicability within other health professions groups.This article is part of a theme issue of Academic Medicine on the Title VII health professions training programs.

Osteoarthritis (OA) is the most common chronic condition and principal cause of disability among older adults. The current obesity epidemic has contributed to this high prevalence rate. Fortunately both OA symptoms and obesity can be ameliorated through lifestyle modifications. Physical activity (PA) combined with weight management improves physical function among obese persons with knee OA but evidence-based interventions that combine PA and weight management are limited for this population. This paper describes a comparative effectiveness trial testing an evidence-based PA program for adults with lower extremity (LE) OA, Fit and Strong!, against an enhanced version that also addresses weight management based on the evidence-based Obesity Reduction Black Intervention Trial (ORBIT). Adult participants (n=400) with LE OA, age 60+, overweight/obese, and not meeting PA requirements of >=150 minutes per week, are randomized to one of the two programs. Both 8-week interventions meet 3 times per week and include 60 minutes of strength, flexibility, and aerobic exercise instruction followed by 30 minutes of education/group discussion. The Fit and Strong! education sessions focus on using PA to manage OA; whereas Fit and Strong! Plus addresses PA and weight loss management strategies. Maintenance of behavior change is reinforced in both groups during months 3 - 24 through telephone calls and mailed newsletters. Outcomes are assessed at baseline, and 2, 6, 12, 18, and 24 months. Primary outcomes are dietary change at 2 months followed by weight loss at 6 months that is maintained at 24 months. Secondary outcomes assess PA, physical performance, and anxiety/depression.

The effect of physical activity (PA) on different areas of academic achievement and classroom behaviors and how different characteristics of PA interventions could modify the effect remain unclear. The objective was twofold: (1) to assess the effect of PA interventions on academic achievement and classroom behaviors in childhood and (2) to determine the characteristics of individuals and PA programs that enhance academic performance. We identified studies from the database inception to October 16, 2016. We selected intervention studies aimed at examining the effect of exercise on academic achievement and classroom behaviors at developmental age. Random-effects models were used to calculate pooled effect size for all primary outcomes (language- and mathematics-related skills, reading, composite score, and time in on-task behavior). Positive values represent a direct relationship between PA programs and academic achievement scores or on-task behaviors. A total of 26 studies (10 205 children, aged from 4 to 13) were included. Pooled effect size (95% confidence interval) estimates were as follows: (1) 0.16 (-0.06 to 0.37) for language-related skills; (2) 0.21 (0.09 to 0.33) for mathematics-related skills; (3) 0.13 (0.02 to 0.24) for reading; (4) 0.26 (0.07 to 0.45) for composite scores; and (5) 0.77 (0.22 to 1.32) for time in on-task behaviors. Limitations included the variety of tools used to measure academic achievement and the limited number of studies that reported the effect of after-school PA interventions. PA, especially physical education, improves classroom behaviors and benefits several aspects of academic achievement, especially mathematics-related skills, reading, and composite scores in youth.

Objective This study examined whether changes in self-efficacy explain the effects of a mailed print intervention on long-term dietary practices of breast and prostate cancer survivors. The relationship between change in self-efficacy and long-term physical activity (PA) also was examined. Methods Breast and prostate cancer survivors (N=543) from 39 U.S. states and two Canadian provinces participated in the FRESH START intervention trial. Participants were randomly assigned to receive a 10-month program of mailed print materials on diet and PA available in the public domain or a 10-month program of tailored materials designed to increase fruit and vegetable (F&V) intake, decrease fat intake, and/or increase PA. Changes in self-efficacy for F&V intake and fat restriction were analyzed as potential mediators of the intervention’s effects on diet at 2-year follow-up. Because we previously found that change in self-efficacy for PA did not vary by group assignment, the relationship between change in self-efficacy and PA at 2-year follow-up was examined across study conditions. Results Results suggest that change in self-efficacy for fat restriction partially explained the intervention’s effect on fat intake (mean indirect effect=-.28), and change in self-efficacy for F&V consumption partially explained the intervention’s effect on daily F&V intake (mean indirect effect=.11). Change in self-efficacy for fat restriction partially accounted for the intervention’s impact on overall diet quality among men only (mean indirect effect=.60). Finally, change in self-efficacy for PA predicted PA at 2-year follow-up. Conclusions Findings suggest that self-efficacy may influence long-term maintenance of healthy lifestyle practices among cancer survivors. PMID:22544562

To examine the effects of different levels of goal specificity and difficulty on Latino children's performance and physical activity (PA) levels in an after-school program incorporating an interactive dance program (Dance Dance Revolution [DDR]; Konami Corporation). Comparison study. Rose Park Elementary School, Salt Lake City, Utah. Ninety-eight Latino children in the first through sixth grades, aged 7 to 13 years. After the pretest, the participants were randomly assigned into 1 of the following 3 goal-setting conditions: (1) easy, (2) difficult, and (3) best effort (hereinafter referred to as do-your-best goal). Participants' PA levels were measured using piezoelectric pedometers, and steps per minute were used as the outcome variable. Participants' total points for their dance on television screens were retrieved as their performance scores. These outcome variables were assessed again 8 weeks later (posttest score). The multivariate analysis of covariance yielded a significant main effect for the goal-setting condition. Follow-up tests revealed that children who set specific (easy or difficult) goals had significantly greater increased PA levels (mean scores, 10.34 for easy and 22.45 for difficult) and DDR performance (0.011 for easy and 0.67 for difficult) than those in the do-your-best group (0.83 for PA and 0.17 for performance). In addition, children's increased PA levels in the difficult-goal group were significantly higher than those in the easy-goal group. The easy- and difficult-goal groups show a significant improvement on DDR performance. The difficult- goal group also displays the highest improvement on PA levels. Strategies to enhance children's DDR performance and PA levels are discussed in relation to the extant goal-setting literature.

Saslow, Sarah A.; Um, Wooyong; Russell, Renee L.

This report describes the results from liquid secondary waste grout (LSWG) formulation and cementitious waste form qualification tests performed by Pacific Northwest National Laboratory (PNNL) for Washington River Protection Solutions, LLC (WRPS). New formulations for preparing a cementitious waste form from a high-sulfate liquid secondary waste stream simulant, developed for Effluent Management Facility (EMF) process condensates merged with low activity waste (LAW) caustic scrubber, and the release of key constituents (e.g. 99Tc and 129I) from these monoliths were evaluated. This work supports a technology development program to address the technology needs for Hanford Site Effluent Treatment Facility (ETF) liquid secondarymore » waste (LSW) solidification and supports future Direct Feed Low-Activity Waste (DFLAW) operations. High-priority activities included simulant development, LSWG formulation, and waste form qualification. The work contained within this report relates to waste form development and testing and does not directly support the 2017 integrated disposal facility (IDF) performance assessment (PA). However, this work contains valuable information for use in PA maintenance past FY17, and for future waste form development efforts. The provided data should be used by (i) cementitious waste form scientists to further understanding of cementitious dissolution behavior, (ii) IDF PA modelers who use quantified constituent leachability, effective diffusivity, and partitioning coefficients to advance PA modeling efforts, and (iii) the U.S. Department of Energy (DOE) contractors and decision makers as they assess the IDF PA program. The results obtained help fill existing data gaps, support final selection of a LSWG waste form, and improve the technical defensibility of long-term waste form performance estimates.« less

This study aimed to examine the effect of a 9-week SPARK program on physical activity (PA), cardiorespiratory endurance (Progressive Aerobic Cardiovascular Endurance Run; PACER), and motivation in middle-school students. 174 students attended baseline and posttests and change scores computed for each outcome. A MANOVA was employed to examine change score differences using follow-up ANOVA and Bonferroni post hoc tests. MANOVA yielded a significant interaction for Grade × Gender × Group (Wilks's Λ = 0.89, P < .001). ANOVA for PA revealed significant differences between SPARK grades 6 and 7 (Mean Δ = 8.11, P < .01) and Traditional grades 6 and 8 (Mean Δ = -6.96, P < .01). ANOVA also revealed greater PACER change for Traditional boys in grade 8 (P < .01) and SPARK girls in grade 8 (P < .01). There were significant interactions with perceived competence differences between SPARK grades 6 and 8 (Mean Δ = 0.38, P < .05), Enjoyment differences between SPARK grades 6 and 7 (Mean Δ = 0.67, P < .001), and SPARK grades 6 and 8 (Mean Δ = 0.81, P < .001). Following the intervention, SPARK displayed greater increases on PA and motivation measures in younger students compared with the Traditional program.

Despite a large body of evidence showing that physical activity (PA) is beneficial to patients with cancer, healthcare professionals (HCPs) are promoting it too scarcely. Factors that hinder HCPs from promoting PA have remained understudied so far. Using a qualitative approach, this study aimed at a comprehensive description of influencing factors for HCPs' PA promotion behaviour and at identifying the reasons and mechanisms behind them. Semi-structured interviews with 30 HCPs were undertaken with a focus on concerns, patient characteristics and structural factors. Answers were analysed using thematic analysis. Results revealed that HCPs had concerns regarding a physical overexertion and psychological stress for patients with cancer. A patient's physical condition and the assumed interest in PA, often derived from former PA, turned out to be the most crucial patient characteristics influencing if PA is addressed. Structural factors relevant for PA promotion pertained to in-house structures, HCPs' workload, timing and coordination, information material for HCPs and patients and availability of exercise programs. In conclusion, this study revealed undetected concerns of HCPs and underlined the relevance of patient characteristics and structural conditions for HCPs' PA promotion towards patients with cancer. A broader perspective is needed to assess these factors in their influence on HCPs' PA promotion. © 2018 John Wiley & Sons Ltd.

Uptake and effectiveness of the Children's Fitness Tax Credit in Canada: the rich get richer

PubMed Central

2010-01-01

Background The Government of Canada implemented a Children's Fitness Tax Credit (CFTC) in 2007 which allows a non-refundable tax credit of up to $500 to register a child in an eligible physical activity (PA) program. The purposes of this study were to assess whether the awareness, uptake, and perceived effectiveness of this tax credit varied by household income among Canadian parents. Methods An internet-based panel survey was conducted in March 2009 with a representative sample of 2135 Canadians. Of those, parents with children aged 2 to 18 years of age (n = 1004) were asked if their child was involved in organized PA programs (including dance and sports), the associated costs to register their child in these programs, awareness of the CFTC, if they had claimed the CFTC for the tax year 2007, and whether they planned to claim it in the upcoming year. Parents were also asked if they believed the CFTC has lead to their child being more involved in PA programs. Results Among parents, 54.4% stated their child was in organized PA and 55.5% were aware of the CFTC. Parents in the lowest income quartile were significantly less aware and less likely to claim the CFTC than other income groups. Among parents who had claimed the CFTC, few (15.6%) believed it had increased their child's participation in PA programs. Conclusions More than half of Canadian parents with children have claimed the CFTC. However, the tax credit appears to benefit the wealthier families in Canada. PMID:20565963

The directionality of the associations of domain-specific physical activity (PA) and sedentary behaviour (SB) with health-related quality of life (HRQoL) in adults remain insufficiently known. This study investigated the longitudinal associations of 10-year cumulative levels of PA and SB with HRQoL and the reverse associations. A sample of 2093 (47.8% men) participants from a cohort of French adult (SU.VI.MAX) was included. Data were collected at 3 time points (1998, 2001 and 2007) using the Modifiable Activity Questionnaire (MAQ) for PA (leisure-time and occupational) and SB (screen-viewing, reading and total sitting time) and the DUKE Health Profile for HRQoL. The cumulative level (from 0 to 3) referred to the number of time points where a high PA level, high SB or good HRQoL was reported. Regression models examined the 10-year cumulative level of PA, SB as predictors of HRQoL and reverse associations. The 10-year cumulative level of high PA, both leisure-time and occupational, predicted a higher HRQoL while the 10-year cumulative level of high screen-viewing time and high total sitting time was associated with lower HRQoL. For the reverse association, cumulative level of good HRQoL predicted more leisure-time PA, less screen-viewing time and less total sitting time but was not related to occupational PA. Relationships between PA, SB and HRQoL are complex and should not be oversimplified in one or the other direction. Taking into account domain-specific PA and SB in health promotion programs appears of prime importance to design interventions aiming at improving HRQoL. Copyright © 2016 Elsevier Inc.

Background: Losing the ability to walk safely and independently is a major concern for many older adults. The Lifestyle Interventions and Independence for Elders study recently demonstrated that a physical activity (PA) intervention can delay the onset of major mobility disability. Our objective is to examine the resources required to deliver the PA intervention and calculate the incremental cost-effectiveness compared with a health education intervention. Methods: The Lifestyle Interventions and Independence for Elders study enrolled 1,635 older adults at risk for mobility disability. They were recruited at eight field centers and randomly assigned to either PA or health education. The PA program consisted of 50-minute center-based exercise 2× weekly, augmented with home-based activity to achieve a goal of 150min/wk of PA. Health education consisted of weekly workshops for 26 weeks, and monthly sessions thereafter. Analyses were conducted from a health system perspective, with a 2.6-year time horizon. Results: The average cost per participant over 2.6 years was US$3,302 and US$1,001 for the PA and health education interventions, respectively. PA participants accrued 0.047 per person more Quality-Adjusted Life-Years (QALYs) than health education participants. PA interventions costs were slightly higher than other recent PA interventions. The incremental cost-effectiveness ratios were US$42,376/major mobility disability prevented and US$49,167/QALY. Sensitivity analyses indicated that results were relatively robust to varied assumptions. Conclusions: The PA intervention costs and QALYs gained are comparable to those found in other studies. The ICERS are less than many commonly recommended medical treatments. Implementing the intervention in non-research settings may reduce costs further. PMID:26888433

Regular physical activity (PA) is a prerequisite for normal growth and maturation, health, and fitness of children and adolescents. Because of the growing evidence of the health benefits of regular PA, several national and international public health organisations have established PA guidelines. The purpose of this study was to assess the percentage of children and adolescents in Germany who meet the PA guideline of 60 minutes of moderate-to-vigorous PA each day and to evaluate socio-demographic correlates of compliance with the PA guideline. The sample consists of 4,529 children and adolescents aged between 4 and 17 years who lived and were registered in the Federal Republic of Germany between 2003 and 2006. The compliance with the PA guideline was assessed using a widely accepted screening measure. Socioeconomic status, immigration background and residential area were assessed using a parent questionnaire. Overall, 13.1% of girls and 17.4% of boys complied with the national guideline of 60 minutes of moderate-to-vigorous PA daily. While compliance was significantly lower in older participants of both gender groups, the steepest decrease in compliance was observed for age groups around the transition time from primary to secondary school. Logistic regression revealed that socioeconomic status and a migration background were significant predictors for compliance in girls and residential area for compliance in boys. Programs and policy action addressing the problem of decreasing compliance with PA guideline with increasing age are warranted. The transition from primary school to secondary school seems to be a critical stage in life with respect to PA behaviour. Therefore, specific interventions should aim at restructuring and reorganising their daily and physical activities during this transition.

The physical activity (PA) levels of many children and adolescents in Australia are currently insufficient to promote health benefits. Physical education (PE) programs aim to promote PA and reach nearly all school-aged children, but PA levels within PE lessons are often low. PE teachers may influence children's motivation to be physically active in PE lessons, but little is known about teacher strategies that effectively motivate children to participate in PA, and few intervention studies have examined motivational strategies in PE. The purpose of this study was to compare the effect of three motivational strategies, each based on Self-Determination Theory (SDT), on PA levels, and their hypothesized antecedents, during year 8 PE lessons. This study employed a cluster-randomized controlled trial design. Following a familiarization session, PA levels and hypothesized PA antecedents were measured during a baseline lesson and a post-intervention or control lesson. Teachers (n = 16) and their classes from five secondary schools in Sydney, Australia were randomly assigned into four blocks and instructed to provide one of four 20-min lesson teaching strategy conditions: (1) explaining the relevance of activities; (2) providing choice from PA options selected by the teacher; (3) providing equipment and free choice of activities; or (4) usual practice. The primary outcomes were lesson time spent in moderate-to-vigorous PA, and motivation towards the lesson. Secondary outcomes were perceptions of teacher behavior, psychological needs satisfaction, and lesson time spent in sedentary behavior. PA and sedentary behavior were measured during baseline and post-intervention lessons with waist-mounted Actigraph GT3X accelerometers. Teacher behavior, psychological needs satisfaction, and motivation were assessed via questionnaires at the end of each lesson. Linear mixed-model analyses will be run on all outcomes, with students nested within teachers as a random effect. Study findings will inform the development of effective SDT-based teaching strategy interventions to enhance students' psychological needs satisfaction, motivation, and PA levels. More effective teaching strategies may be identified that are capable of improving adolescents' PA levels, and thereby provide beneficial population health outcomes. This trial is registered with Current Controlled Trials and is traceable as ISRCTN07038258.

Teachers (n = 16) and their classes from five secondary schools in Sydney, Australia were randomly assigned into four blocks and instructed to provide one of four 20-min lesson teaching strategy conditions: (1) explaining the relevance of activities; (2) providing choice from PA options selected by the teacher; (3) providing equipment and free choice of activities; or (4) usual practice. The primary outcomes were lesson time spent in moderate-to-vigorous PA, and motivation towards the lesson. Secondary outcomes were perceptions of teacher behavior, psychological needs satisfaction, and lesson time spent in sedentary behavior. PA and sedentary behavior were measured during baseline and post-intervention lessons with waist-mounted Actigraph GT3X accelerometers. Teacher behavior, psychological needs satisfaction, and motivation were assessed via questionnaires at the end of each lesson. Linear mixed-model analyses will be run on all outcomes, with students nested within teachers as a random effect. Discussion Study findings will inform the development of effective SDT-based teaching strategy interventions to enhance students’ psychological needs satisfaction, motivation, and PA levels. More effective teaching strategies may be identified that are capable of improving adolescents’ PA levels, and thereby provide beneficial population health outcomes.

Background Physical activity (PA) for older adults has well-documented physical and cognitive benefits, but most seniors do not meet recommended guidelines for PA, and interventions are lacking. Objectives This study evaluated the efficacy of a 12-week Internet intervention to help sedentary older adults over 55 years of age adopt and maintain an exercise regimen. Methods A total of 368 sedentary men and women (M=60.3; SD 4.9) were recruited, screened, and assessed online. They were randomized into treatment and control groups and assessed at pretest, at 12 weeks, and at 6 months. After treatment group participants rated their fitness level, activity goals, and barriers to exercise, the Internet intervention program helped them select exercise activities in the areas of endurance, flexibility, strengthening, and balance enhancement. They returned to the program weekly for automated video and text support and education, with the option to change or increase their exercise plan. The program also included ongoing problem solving to overcome user-identified barriers to exercise. Results The multivariate model indicated significant treatment effects at posttest (P=.001; large effect size) and at 6 months (P=.001; medium effect size). At posttest, intervention participation showed significant improvement on 13 of 14 outcome measures compared to the control participants. At 6 months, treatment participants maintained large gains compared to the control participants on all 14 outcome measures. Conclusions These results suggest that an online PA program has the potential to positively impact the physical activity of sedentary older adult participants. More research is needed to replicate the study results, which were based on self-report measures. Research is also needed on intervention effects with older populations. PMID:23470322

The effectiveness of clinical-community linkages for promotion of physical activity (PA) has not been explored in low- and middle-income countries. This study assessed the effectiveness of a primary care-based, 16-week intervention rooted in behavioral theory approaches to increase compliance with aerobic PA recommendations. Pragmatic cluster randomized trial. Patients had diagnosed (<5 years) hypertension, were aged 35-70 years, self-reported as physically inactive, had a stated intention to engage in PA, and attended Primary Healthcare Centers in the Social Security health system in Cuernavaca, Mexico. Of 23 Primary Healthcare Centers, four were selected based on proximity (5 km radius) to a center. Each center was randomized to a brief PA counseling (BC, n=2) or an exercise referral (ER, n=2) intervention. The study was conducted between 2011 and 2012. Change in objectively measured PA levels (ActiGraph GT3X accelerometers) at baseline, 16, and 24 weeks. Intention-to-treat analyses were used to assess the effectiveness of the intervention overall and according to ER intervention attendance. Longitudinal multilevel mixed-effects analyses considering the interaction (time by intervention) were conducted. Each model was also adjusted by baseline value of the outcome measure, demographic and health variables, social support, PA self-efficacy, and barriers. Minutes/week of objectively measured moderate to vigorous PA increased by 40 and 53 minutes in the ER and BC groups, respectively (p=0.59). Participants attending >50% of ER program sessions increased their moderate to vigorous PA by 104 minutes/week and compliance with aerobic PA recommendations by 23.8%, versus the BC group (both p<0.05). Both BC and ER led to modest improvements in PA levels, with no significant differences between groups. Adequate adherence with the ER program sessions led to significant improvements in compliance with aerobic PA recommendations versus BC. These results can help guide development and implementation of programs integrating standardized PA assessment, counseling, and referrals via clinical-community linkages in Mexico and other low- and middle-income countries in the region.

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders.

2014-05-01

To examine the impact of telephone reinforcement (TR) on predictors of physical activity (PA) maintenance in older adults with osteoarthritis. Mixed effects modeling was conducted of data from a randomized PA trial that used negotiated maintenance contracts, supplemented by TR, to test impact of TR on barriers, decisional balance, and stage of change at multiple points in time. Participants who were referred to a PA program and received TR improved the most in barriers and decisional balance. Participants who negotiated a tailored maintenance contract but did not receive TR improved the most in stage. TR appears to positively affect perceptions around engagement, whereas negotiation positively impacts PA behavior. Further research should examine the effectiveness of specific PA maintenance strategies.

FY2010 ANNUAL REVIEW E-AREA LOW-LEVEL WASTE FACILITY PERFORMANCE ASSESSMENT AND COMPOSITE ANALYSIS

2011-01-01

The E-Area Low-Level Waste Facility (ELLWF) consists of a number of disposal units described in the Performance Assessment (PA)(WSRC, 2008b) and Composite Analysis (CA)(WSRC, 1997; WSRC, 1999): Low-Activity Waste (LAW) Vault, Intermediate Level (IL) Vault, Trenches (Slit Trenches [STs], Engineered Trenches [ETs], and Component-in-Grout [CIG] Trenches), and Naval Reactor Component Disposal Areas (NRCDAs). This annual review evaluates the adequacy of the approved 2008 ELLWF PA along with the Special Analyses (SAs) approved since the PA was issued. The review also verifies that the Fiscal Year (FY) 2010 low-level waste (LLW) disposal operations were conducted within the bounds of the PA/SAmore » baseline, the Savannah River Site (SRS) CA, and the Department of Energy (DOE) Disposal Authorization Statement (DAS). Important factors considered in this review include waste receipts, results from monitoring and research and development (R&D) programs, and the adequacy of controls derived from the PA/SA baseline. Sections 1.0 and 2.0 of this review are a summary of the adequacy of the PA/SA and CA, respectively. An evaluation of the FY2010 waste receipts and the resultant impact on the ELLWF is summarized in Section 3.1. The results of the monitoring program, R&D program, and other relevant factors are found in Section 3.2, 3.3 and 3.4, respectively. Section 4.0 contains the CA annual determination similarly organized. SRS low-level waste management is regulated under DOE Order 435.1 (DOE, 1999a) and is authorized under a DAS as a federal permit. The original DAS was issued by the DOE-Headquarters (DOE-HQ) on September 28, 1999 (DOE, 1999b) for the operation of the ELLWF and the Saltstone Disposal Facility (SDF). The 1999 DAS remains in effect for the regulation of the SDF. Those portions of that DAS applicable to the ELLWF were superseded by revision 1 of the DAS on July 15, 2008 (DOE, 2008b). The 2008 PA and DAS were officially implemented by the facility on October 31, 2008 and are the authorization documents for this FY2010 Annual Review. Department of Energy Headquarters approval of the 2008 DAS was subject to numerous conditions specified in the document. Two of those conditions are to update the ELLWF closure plan and monitoring plan to align with the conceptual model analyzed in the PA. Both of these conditions were met with the issuance of the PA Monitoring Plan (Millings, 2009a) and the Closure Plan (Phifer et al, 2009a). The PA Monitoring Plan was approved by DOE on July 22, 2009 and the Closure Plan was approved by DOE on May 21, 2009. Both will be updated as needed to remain consistent with the PA. The DAS also specifies that the maintenance plan include activities to resolve each of the secondary issues identified in the DOEHQ review of the 2008 PA that were not completely addressed either with supplemental material provided to the review team or in final revisions to the PA. These outstanding issues were originally documented in the 2008 update of the PA/CA Maintenance Plan (WSRC, 2008a) and in subsequent PA/CA Maintenance Plans (most recently SRNS, 2010a) as required and are actively being worked.« less

To implement a culturally tailored physical activity (PA) promotion program (FunAction) and to assess its impact on five self-regulation skills and attitudes in adolescents. Design . The design and implementation of the FunAction program were informed by social marketing principles. The study used a quasi-experimental approach to assess the impact of the program on specific outcome variables. A multiethnic, underserved middle school in Montreal, Quebec, Canada. The intervention group was made up of grade 8 students (n  =  165) and the control group was made up of grade 7 students (n  =  137). During the 16-week intervention, adolescents were able to choose from a variety of 45-minute cardiovascular PAs offered daily during their school lunch period. Adolescents participated in the activities on a voluntary basis. A self-report questionnaire was administered preintervention and postintervention to measure adolescents' scores on the following self-regulation skills and attitudes: self-control, self-esteem, attention/concentration, social competence, and interethnic relationships. Three-way repeated measures analyses of variance and correlational analyses were used. Results . A significant improvement was observed only in attention/concentration. Girls' attention/concentration scores improved significantly in the intervention group compared to the control group (F(1,127)  =  16.26, p < .001). The improvement in attention/concentration scores for boys in the intervention group was correlated with their frequency of participation in the program PAs (r  =  .24, p  =  .008). Using social marketing principles can help encourage adolescents from underserved, multiethnic milieus to participate in PA during their school lunch hour. Furthermore, voluntary participation in a culturally tailored PA program can improve youths' attention/concentration.

Using Objective, Real-Time Measures to Investigate the Effect of Actual Physical Activity on Affective States in Everyday Life Differentiating the Contexts of Working and Leisure Time in a Sample with Students

PubMed Central

Kanning, Martina

2013-01-01

Multiple studies suggest that physical activity causes positive affective reactions and reduces depressive mood. However, studies and interventions focused mostly on structured activity programs, but rarely on actual physical activity (aPA) in daily life. Furthermore, they seldom account for the context in which the aPA occur (e.g., work, leisure). Using a prospective, real-time assessment design (ambulatory assessment), we investigated the effects of aPA on affective states (valence, energetic arousal, calmness) in real-time during everyday life while controlling for the context. Eighty-seven undergraduates students (Age: M = 24.6; SD = 3.2, females: 54%) participated in this study. aPA was assessed through accelerometers during 24-h. Palmtop devices prompted subjects approximately every 45 min during a 14-h daytime period to assess their affective states and the context. We analyzed within- and between-person effects with hierarchical modeling (HLM 6.0). Multilevel analyses revealed that both aPA and context influenced subsequent affective states. The interaction of aPA and context did predict energetic arousal only. State levels of affects did not differ between men and women. For both men and women, aPA in everyday life has an effect on individual’s affective states. For valence and calmness, it seems to be independent of the context in which the aPA occur. For energetic arousal, men reported to have lower feelings of energy and women reported to have more feelings of energy during leisure time compared to working episodes. PMID:23346064

Objective This study evaluated the effect of two home-based exercise interventions (one culturally-adapted and one standard) on changes in Social Cognitive Theory (SCT) variables, physical activity (PA) and sedentary time (ST), and to determine the association between changes in SCT variables and changes in PA and ST in Hispanic breast cancer survivors. Method Project VIVA! was a 16-week randomized controlled pilot study to test the effectiveness and feasibility of a culturally-adapted exercise intervention for Mexican American and Puerto Rican breast cancer survivors in Houston, Texas and San Juan, Puerto Rico, respectively. Women (N=89) completed questionnaires on SCT variables, PA and ST and were then randomized to a 16-week culturally-adapted exercise program, a non-culturally adapted standard exercise intervention or a wait-list control group. Multiple regression models were used to determine associations between changes in SCT variables and changes in PA and ST. Results Participants were in their late 50s (58.5 ± 9.2 years) and obese (31.0 ± 6.5 kg/m2). Women reported doing roughly 34.5 minutes/day of PA and spending over 11 hours/day in sedentary activities. Across groups, women reported significant increases in exercise self-efficacy and moderate-intensity, vigorous-intensity, and total physical activity from baseline to follow-up (p<.05). Increased social support from family was associated with increases in vigorous-intensity PA. Increases in social modeling were associated with increases in moderate-intensity and total PA and decreases in ST from baseline to follow-up (p<.05). Conclusions Hispanic cancer survivors benefit from PA interventions that focus on increasing social support from family and friends and social modeling. PMID:26602701

Einwanger, Jürgen; Hartl, Arnulf; Kopp, Martin

2017-01-01

Introduction Affective responses during physical activity (PA) are important for engagement in PA programs and for adherence to a physically active lifestyle. Little is known about the affective responses to PA bouts lasting longer than 45 minutes. Therefore, the aims of the present study were to analyse acute effects on affective responses of a three-hour outdoor PA intervention (mountain hiking) compared to a sedentary control situation and to an indoor treadmill condition. Methods Using a randomized crossover design, 42 healthy participants were randomly exposed to three different conditions: outdoor mountain hiking, indoor treadmill walking, and sedentary control situation (approximately three hours each). Measures included the Feeling Scale, Felt Arousal Scale and a Mood Survey Scale. Repeated measures ANOVAs were used to analyse differences between the conditions. Results Compared to the control situation, the participants showed a significant increase in affective valence (d = 1.21, p < .001), activation (d = 0.81, p = .004), elation (d = 1.07, p < .001), and calmness (d = 0.84, p = .004), and a significant decrease in fatigue (d = -1.19, p < .001) and anxiety (d = -.79, p < .001) after mountain hiking. Outdoor mountain hiking showed significantly greater positive effects on affective valence, activation, and fatigue compared to indoor treadmill walking. Discussion The results indicate that a three-hour PA intervention (mountain hiking) elicits higher positive and lower negative affective responses compared to a sedentary control situation and to an indoor PA condition. Outdoor mountain hiking can be recommended by health professionals as a form of PA with the potential to positively influence affective responses.

Insight into modifiable factors related to falls risk in older adults living in residential aged care facilities (RACFs) is necessary to tailor preventive strategies for this high-risk population. Associations between physical activity (PA), physical performance and psycho-cognitive functioning have been understudied in aged care residents. This study investigated associations between PA, and both physical performance and psycho-cognitive functioning in older adults living in RACFs. Cross-sectional study. Forty-four residents aged 85±8years were recruited from four RACFs located in Southeast Queensland. PA was assessed as the average time spent walking in hours/day using activPAL3™. Physical performance tests included balance, gait speed, dual-task ability, reaction time, coordination, grip strength, and leg strength and power. Psycho-cognitive questionnaires included quality of life, balance confidence, fear of falling and cognitive functioning. Associations between PA and each outcome measure were analysed using linear or ordinal regression models. The average time spent walking was 0.5±0.4h/day. Higher levels of PA were significantly associated with better balance (compared with low PA, medium: B=1.6; high: B=1.3) and dual-task ability (OR=7.9 per 0.5h/day increase). No statistically significant associations were found between PA and the other physical and psycho-cognitive measures. More physically active residents scored higher on balance and dual-task ability, which are key predictors of falls risk. This suggests that physical activity programs targeting balance and dual-task ability could help prevent falls in aged care residents. Copyright © 2017 Sports Medicine Australia.

School-based physical activity (PA) interventions, including school active transportation (AT), provide opportunities to increase daily PA levels, improves fitness, and reduces risk of diseases, such as type 2 diabetes. Based on a community-identified need, the Kahnawake Schools Diabetes Prevention Project, within an Indigenous community, undertook school travel planning to contribute to PA programming for two elementary schools. Using community-based participatory research, the Active & Safe Routes to School's School Travel Planning (STP) process was undertaken in two schools with an STP-Committee comprised of community stakeholders and researchers. STP activities were adapted for local context including: school profile form, family survey, in-class travel survey, pedestrian-traffic observations, walkability checklist, and student mapping. STP data were jointly collected, analyzed and interpreted by researchers and community. Traffic-pedestrian observations, walkability and parent surveys identified key pedestrian-traffic locations, helped develop safe/direct routes, and traffic calming strategies. In-class travel and mapping surveys identified a need and student desire to increase school AT. The STP-Committee translated findings into STP-action plans for two schools, which were implemented in 2014-2015 school year. Combining CBPR with STP merges community and researcher expertise. This project offered evidence-informed practice for active living promotions. Experience and findings could benefit Indigenous and non-Indigenous communities. Copyright © 2016 Elsevier Ltd.

Background: HMG-CoA reductase inhibitors (statins) are among the most commonly prescribed classes of medications. Although their cardiovascular benefits and myalgia risks are well documented, their effects on older adults initiating an exercise training program are less understood. Methods: 1,635 sedentary men and women aged 70–89 years with Short Physical Performance Battery (SPPB) score of 9 or below and were able to walk 400 m were randomized to a structured, moderate-intensity physical activity (PA) program consisting of both center-based (twice/wk) and home-based (3–4 times/wk) aerobic, resistance, and flexibility training or to a health education (HE) program combined with upper extremity stretching. Results: Overall, the PA intervention was associated with lower risk of major mobility disability (hazard ratio [HR] = 0.82; 95% confidence interval [CI] = 0.69–0.98). The effect was similar (p value for interaction = .62) in both statin users (PA n = 415, HE n = 412; HR = 0.86, 95% CI = 0.67–1.1) and nonusers (PA n = 402, HE n = 404; HR = 0.78, 95% CI = 0.61–1.01). Attendance was similar for statin users (65%) and nonusers (63%). SPPB at 12 months was slightly greater for PA (8.35±0.10) than for HE (7.94±0.10) in statin users but not in nonusers (PA 8.25±0.10, HE 8.16±0.10), though the interaction effect was not statistically significant. Self-reported PA levels were not different between statin users and nonusers. Conclusions: Although statins have been associated with adverse effects on muscle, data from the LIFE Study show that statin users and nonusers both benefit from PA interventions. Older adults who require statin medications to manage chronic medical conditions and are sedentary will be able to benefit from interventions to increase PA. PMID:26988662

Age-Associated Perceptions of Physical Activity Facilitators and Barriers Among Women in Rural Southernmost Illinois

2016-01-01

Introduction Women living in rural areas in the United States experience disproportionately high rates of diseases such as obesity and heart disease and are less likely than women living in urban areas to meet daily physical activity (PA) recommendations. The purpose of our research was to understand age-specific perceptions of barriers and facilitators to rural women engaging in PA and to identify strategies to promote PA among these women. Methods As part of a community health assessment to learn about women’s health issues, 110 adult women participated in 14 focus groups. The women were divided into 4 age groups, and focus groups were held in various community settings. We used qualitative analysis methods to explore themes in the women’s narratives, including themes related to PA knowledge, PA behavior, and access to PA facilities. Results Participants described multiple and often conflicting individual, social, and environmental barriers and facilitators to PA. Several barriers and facilitators were shared across age groups (eg, competing priorities and inadequate knowledge about PA’s role in disease prevention and disease management). Other barriers (eg, illness and injury) and facilitators (eg, PA as a social opportunity) differed by age group. Conclusion Rural women in southernmost Illinois have often contradictory barriers and facilitators to PA, and those barriers and facilitators are different at different points in a woman’s life. Our findings suggest the need for multilevel, multisector approaches to promote PA. Additionally, this research supports the need for tailored PA promotion programs for rural women to address the barriers these women face across their lifespan. PMID:27685431

A school-based intervention program in promoting leisure-time physical activity: trial protocol.

Regular participation in moderate-to-vigorous physical activity (MVPA) is important to manage obesity. Physical education (PE) is considered to play an important role in promoting lifelong participation in physical activity (PA) because it provides an existing network where cost-effective interventions can be implemented to produce sustainable change in health behavior. However, the association between compulsory school PA (e.g., PE lessons) and body composition levels has received mixed support in the literature. Therefore, the present study aimed to investigate whether a school-based intervention targeting salient PA benefits and barriers grounded on the theory of planned behavior would promote young people's participation in MVPA during leisure time and reduce body mass index (BMI) of overweight students. A total of 171 students from 3 secondary schools in Singapore underwent the control condition followed by the intervention condition. Both the conditions consisted of PE lessons twice per week over 4 weeks. In the control condition, PE teachers encouraged students to participate in PA during leisure time without providing persuasive message. While in the intervention condition, PE teachers delivered persuasive messages that targeted the salient benefits and barriers associated with PA to the students at the last 5 to 10 min of each PE lesson. PA levels over a week were measured objectively with wrist-mounted GENEActiv Original accelerometers and subjectively with self-reporting questionnaires three times (Baseline, Post 1, and Post 2) in each condition. Student's self-reported PA level was measured using the Leisure-Time Physical Activity Participation Questionnaire and the International Physical Activity Questionnaire, and their attitudes, intentions, subjective norms and perceived behavior control towards leisure-time PA were measured with a questionnaire based on the theory of planned behavior. Furthermore, students' intention, determination and willingness to engage in leisure-time PA were compared with the other activity (e.g., doing homework, shopping). This study will provide the evidence on the effectiveness of a cost-effective school-based intervention on reducing BMI of overweight students through promoting sustained participation in leisure-time PA. It will also address methodological issues on the gaps between objective and subjective measures of PA. This trial is registered with the ISRCTN registry (ISRCTN73786157, 26/10/2017, retrospectively registered).

Physical Activity and Exercise: Perspectives of Adults With Ankylosing Spondylitis.

2016-05-01

Exercise is a key component of the management of ankylosing spondylitis (AS). Despite numerous benefits, compliance with exercise programs is low. Little attention has been accorded to the experiences of individuals with AS toward physical activity (PA). This study aimed to explore the attitudes toward PA and exercise of adults with AS. A qualitative descriptive design using thematic analysis was used. Seventeen adults with AS participated in individual, semistructured interviews. Interviews were recorded, transcribed, coded and analyzed for themes and subthemes. Four themes emerged from the analysis: (1) benefits, (2) barriers, (3) motivation, and (4) strategies and enablers. Benefits included amelioration of symptoms, improvements in general health, and enhancement of quality of life. Subthemes of barriers to PA included lack of resources, negative attitudes to exercise, misinformation, and condition-related factors. Motivation to exercise was influenced by intrinsic and extrinsic factors. Participants proposed strategies to enhance PA participation and exercise engagement. Awareness of the benefits of PA appears insufficient to motivate individuals with AS to exercise; a number of factors influence individual motivation to exercise. Many perceived barriers to PA may be considered modifiable. Individually-tailored interventions, collaboratively developed by the individual and the healthcare professionals, were proposed as strategies for effective PA and exercise prescription.

Using the Internet to promote physical activity: a randomized trial of intervention delivery modes.

2007-07-01

A growing number of the population are using the Internet for health information, such as physical activity (PA). The aim of this study was to examine the effectiveness of delivery modes for a behavior change program targeting PA. A randomized trial was conducted with 192 subjects randomly allocated to either a face-to-face, Internet-mediated, or Internet-only arm of a 12-wk intervention. Subjects included inactive adults with Internet access. The primary outcome variable was self-reported PA, assessed at four time points. The results showed no group x time interaction for PA F(6, 567) = 1.64, p > 0.05, and no main effect for group F(2, 189) = 1.58, p > 0.05. However, a main effect for time F(3, 567) = 75.7, p < 0.01 was observed for each group. All groups were statistically equivalent immediately post-intervention (p < 0.05), but not at the follow-up time points (p > 0.05). The Internet-mediated and Internet-only groups showed similar increases in PA to the face-to-face group immediately post-intervention. This study provides evidence in support of the Internet in the delivery of PA interventions and highlights avenues for future research.

Cisplatin is a classic chemotherapeutic agent widely used to treat different types of cancers including ovarian, head and neck, testicular and uterine cervical carcinomas. However, cisplatin induces acute kidney injury by directly triggering an excessive inflammatory response, oxidative stress, and programmed cell death of renal tubular epithelial cells, all of which lead to high mortality rates in patients. In this study, we examined the protective effect of protocatechuic aldehyde (PA) in vitro in cisplatin-treated tubular epithelial cells and in vivo in cisplatin nephropathy. PA is a monomer of Traditional Chinese Medicine isolated from the root of S. miltiorrhiza (Lamiaceae). Results show that PA prevented cisplatin-induced decline of renal function and histological damage, which was confirmed by attenuation of KIM1 in both mRNA and protein levels. Moreover, PA reduced renal inflammation by suppressing oxidative stress and programmed cell death in response to cisplatin, which was further evidenced by in vitro data. Of note, PA suppressed NAPDH oxidases, including Nox2 and Nox4, in a dosage-dependent manner. Moreover, silencing Nox4, but not Nox2, removed the inhibitory effect of PA on cisplatin-induced renal injury, indicating that Nox4 may play a pivotal role in mediating the protective effect of PA in cisplatin-induced acute kidney injury. Collectively, our data indicate that PA blocks cisplatin-induced acute kidney injury by suppressing Nox-mediated oxidative stress and renal inflammation without compromising anti-tumor activity of cisplatin. These findings suggest that PA and its derivatives may serve as potential protective agents for cancer patients receiving cisplatin treatment. PMID:27999546

Physical activity (PA) has been linked to a lower risk of developing and dying of cancer, yet many cancer survivors do not exercise. In the current study, the authors evaluated the impact of the LIVESTRONG at the YMCA exercise program, available at Young Men's Christian Associations (YMCAs) across the United States, on PA, fitness, quality of life, fatigue, body composition, serum biomarkers, and program safety in cancer survivors. Cancer survivors were recruited through the Yale Cancer Center and the Dana-Farber Cancer Institute and randomized to a 12-week, twice-weekly LIVESTRONG at the YMCA exercise program at YMCAs in Connecticut or Massachusetts or to a control group. Questionnaires, dual-energy x-ray absorptiometry scans, 6-minute walk tests (6MWTs), and a fasting blood draw were completed at baseline and at 12 weeks. Intervention effects were evaluated using mixed model repeated measures analysis, with changes at 12 weeks in PA and 6MWT as the primary endpoints. A total of 186 participants were randomized (95 to the exercise group and 91 to the control group). The majority of patients were diagnosed with AJCC stage I to II cancer and 53% had breast cancer. Participants randomized to the LIVESTRONG at the YMCA program experienced increases in PA (71% exercising at ≥ 150 minutes/week vs 26% of controls; P<.05) and improvements in the 6MWT (group difference: 28.9 meters [95% confidence interval, 0.3-49.0; P = .004]) and quality of life (group difference: 2.6 [95% confidence interval, 0.1-5.0; P = .04]). No adverse events were reported. The LIVESTRONG at the YMCA exercise program has the potential to impact thousands of survivors across the YMCA network and could lead to improvements in disease and psychosocial outcomes in the growing population of cancer survivors.

Candidate mechanisms accounting for effects of physical activity on breast carcinogenesis.

PubMed

Evidence is strong that a reduction in risk for breast cancer is associated with moderate to vigorous physical activity (PA); however, there is limited understanding of the role of type, intensity, duration, and frequency of PA and their mechanisms in accounting for this health benefit. The objective of this review is to stimulate investigations of candidate mechanisms that may account for the effects of the intensity and duration of aerobic PA on breast cancer risk and tumor burden. Three hypotheses are considered: 1) the mTOR network hypothesis: PA inhibits carcinogenesis by suppressing the activation of the mTOR signaling network in mammary carcinomas; 2) the hormesis hypothesis: the carcinogenic response to PA is nonlinear and accounted for by a physiological cellular stress response; and 3) the metabolic reprogramming hypothesis: PA limits the amount of glucose and glutamine available to mammary carcinomas thereby inducing apoptosis because tumor-associated metabolic programming is reversed. To link these hypotheses to systemic effects of PA, it is recommended that consideration be given to determining: 1) what contracting muscle releases into circulation or removes from circulation that would directly modulate the carcinogenic process in epithelial cells; 2) whether the effects of muscle contraction on epithelial cell carcinogenesis are exerted in an endocrine, paracrine, autocrine, or intracrine manner; and 3) if the effects of muscle contraction on malignant cells differ from effects on normal or premalignant cells that do not manifest the hallmarks of malignancy.

Osteoarthritis (OA) is the most common chronic condition and principal cause of disability among older adults. The current obesity epidemic has contributed to this high prevalence rate. Fortunately both OA symptoms and obesity can be ameliorated through lifestyle modifications. Physical activity (PA) combined with weight management improves physical function among obese persons with knee OA but evidence-based interventions that combine PA and weight management are limited for this population. This paper describes a comparative effectiveness trial testing an evidence-based PA program for adults with lower extremity (LE) OA, Fit and Strong!, against an enhanced version that also addresses weight management based on the evidence-based Obesity Reduction Black Intervention Trial (ORBIT). Adult participants (n=400) with LE OA, age 60+, overweight/obese, and not meeting PA requirements of ≥ 150 min per week, are randomized to one of the two programs. Both 8-week interventions meet 3 times per week and include 60 min of strength, flexibility, and aerobic exercise instruction followed by 30 min of education/group discussion. The Fit and Strong! education sessions focus on using PA to manage OA; whereas Fit and Strong! Plus addresses PA and weight loss management strategies. Maintenance of behavior change is reinforced in both groups during months 3-24 through telephone calls and mailed newsletters. Outcomes are assessed at baseline, and 2, 6, 12, 18, and 24 months. Primary outcomes are dietary change at 2 months followed by weight loss at 6 months that is maintained at 24 months. Secondary outcomes assess PA, physical performance, and anxiety/depression.

Over 21 million Americans report an arthritis-attributable activity limitation. Knee osteoarthritis (OA) and rheumatoid arthritis (RA) are two of the most common/disabling forms of arthritis. Various forms of physical activity (PA) can improve a variety of health outcomes and reduce health care costs, but the proportion of the US population engaging in the recommended amount of PA is low and even lower among those with arthritis. The Improving Motivation for Physical Activity in Arthritis Clinical Trial (IMPAACT) is a randomized clinical trial that studied the effects of a lifestyle PA promotion intervention on pain and physical function outcomes. The IMPAACT intervention was based on a chronic care/disease management model in which allied health professionals promote patient self-management activities outside of traditional physician office encounters. The program was a motivational interviewing-based, individualized counseling and referral intervention, directed by a comprehensive assessment of individual patient barriers and strengths related to PA performance. The specific aims of IMPAACT were to test the efficacy of the IMPAACT intervention for persons with arthritis (N=185 persons with RA and 155 persons with knee OA) in improving arthritis-specific and generic self-reported pain and Physical Function outcomes, observed measures of function, and objectively measured and self-reported PA levels. Details of the stratified-randomized study design, subject recruitment, and data collection are described. The results from IMPAACT will generate empiric evidence pertaining to increasing PA levels in persons with arthritis and result in widely applicable strategies for health behavior change.

Background Type 2 diabetes is a major challenge for Canadian public health authorities, and regular physical activity is a key factor in the management of this disease. Given that fewer than half of people with type 2 diabetes in Canada are sufficiently active to meet the recommendations, effective programs targeting the adoption of regular physical activity (PA) are in demand for this population. Many researchers argue that Web-based, tailored interventions targeting PA are a promising and effective avenue for sedentary populations like Canadians with type 2 diabetes, but few have described the detailed development of this kind of intervention. Objective This paper aims to describe the systematic development of the Web-based, tailored intervention, Diabète en Forme, promoting regular aerobic PA among adult Canadian francophones with type 2 diabetes. This paper can be used as a reference for health professionals interested in developing similar interventions. We also explored the integration of theoretical components derived from the I-Change Model, Self-Determination Theory, and Motivational Interviewing, which is a potential path for enhancing the effectiveness of tailored interventions on PA adoption and maintenance. Methods The intervention development was based on the program-planning model for tailored interventions of Kreuter et al. An additional step was added to the model to evaluate the intervention’s usability prior to the implementation phase. An 8-week intervention was developed. The key components of the intervention include a self-monitoring tool for PA behavior, a weekly action planning tool, and eight tailored motivational sessions based on attitude, self-efficacy, intention, type of motivation, PA behavior, and other constructs and techniques. Usability evaluation, a step added to the program-planning model, helped to make several improvements to the intervention prior to the implementation phase. Results The intervention development cost was about CDN $59,700 and took approximately 54 full-time weeks. The intervention officially started on September 29, 2014. Out of 2300 potential participants targeted for the tailored intervention, approximately 530 people visited the website, 170 people completed the registration process, and 83 corresponded to the selection criteria and were enrolled in the intervention. Conclusions Usability evaluation is an essential step in the development of a Web-based tailored intervention in order to make pre-implementation improvements. The effectiveness and relevance of the theoretical framework used for the intervention will be analyzed following the process and impact evaluation. Implications for future research are discussed.

This study was conducted to examine the relationship between physician assistant (PA) educational program length and PA programs' 5-year average Physician Assistant National Certifying Examination (PANCE) first-time pass rates. This was a retrospective correlational study that analyzed previously collected data from a nonprobability purposive sample of accredited PA program Web sites. Master's level PA programs (n = 108) in the United States with published average PANCE scores for 5 consecutive classes were included. Provisional and probationary programs were excluded (n = 4). Study data were not normally distributed per the Kolmogorov-Smirnov test, P = .00. There was no relationship between program length and PANCE pass rates, ρ (108) = -0.04, P = .68. Further analyses examining a possible relationship between program phase length (didactic and clinical) and PANCE pass rates also demonstrated no differences (ρ [107] = -0.05, P = .60 and ρ [107] = 0.02, P = .80, respectively). The results of this study suggest that shorter length PA programs perform similarly to longer programs in preparing students to pass the PANCE. In light of rapid expansion of PA educational programs, educators may want to consider these findings when planning the length of study for new and established programs.

Comprehensive school physical activity programs (CSPAPs) have been endorsed as a promising strategy to increase youth physical activity (PA) in school settings. A CSPAP is a five-component approach, which includes opportunities before, during, and after school for PA. Extensive resources are available to public health practitioners and school officials regarding what should be implemented, but little guidance and few resources are available regarding how to effectively implement a CSPAP. Implementation science provides a number of conceptual frameworks that can guide implementation of a CSPAP, but few published studies have employed an implementation science framework to a CSPAP. Therefore, we developed Be a Champion! (BAC), which represents a synthesis of implementation science strategies, modified for application to CSPAPs implementation in schools while allowing for local tailoring of the approach. This article describes BAC while providing examples from the implementation of a CSPAP in three rural elementary schools. PMID:29354631

Overweight and obesity are growing health problems both worldwide and in Malaysia due to such lifestyle changes as decreased physical activity (PA), increased sedentary behavior and unhealthy eating habits. This study examined the levels and patterns of PA among normal-weight and overweight/obese adults and to investigate the association between PA level and overweight/obesity in Malaysian adults. This study used data from the 2015 National Health and Morbidity Survey (NHMS), a nationwide cross-sectional survey that implemented a two-stage stratified random sampling design. Respondents aged 18 years and above (n = 17,261) were included in the analysis. The short version of International Physical Activity Questionnaire (IPAQ) was administered to assess the respondents' PA levels. The respondents' height and weight were objectively measured and body mass index (BMI) was calculated. The respondents were categorized according to BMI as either normal-weight (18.5-24.9 kg/m 2 ) or overweight/obese (≥ 25 kg/m 2 ). Descriptive and complex sample logistic regression analyses were employed as appropriate. Overall, approximately 1 in 2 respondents (51.2%) were overweight/obese, even though the majority (69.0%) reporting at least a moderate level of PA (total PA ≥ 10 MET-hours/week). In both normal-weight and overweight/obese groups, a significantly higher prevalence of high PA (total PA ≥ 50 MET-hours/week) was observed among men than women (p < 0.001), but women reported a significantly higher prevalence of low and moderate PA than men (p < 0.001). Men reported significantly higher activity levels (in MET-hours/week) than women with regard to walking, vigorous-intensity PA and total PA (p < 0.001). Overweight/obese men reported a significantly lower level of vigorous-intensity PA and total PA than normal-weight men (p < 0.001). A low level of PA was associated with the risk of overweight/obesity (Adjusted OR = 1.14; 95% CI: 1.01-1.30) compared to a high level of PA among men but not among women. The levels of PA were inversely related to the risk of overweight/obesity in men but not in women. Programs designed to reduce overweight/obesity rates should encourage the practice of moderate- to vigorous-intensity PA. Future research should consider using longitudinal and prospective approaches that simultaneously measure dietary intake, PA and BMI among Malaysian adults to investigate the actual relationship between PA and overweight/obesity.

Substantial data have established that higher levels of physical activity (PA), participating in exercise training (ET), and higher overall cardiorespiratory fitness (CRF) provide considerable protection in the primary and secondary prevention of coronary heart disease (CHD). This review surveys data from epidemiological and prospective ET studies supporting the favorable impact of PA, ET, and CRF in primary CHD prevention. Clearly, cardiac rehabilitation and ET (CRET) programs have been underutilized for patients with CHD, particularly considering the effect of CRET on CHD risk factors, including CRF, obesity indices, fat distribution, plasma lipids, inflammation, and psychological distress, as well as overall morbidity and mortality. These data strongly support the routine referral of patients with CHD to CRET programs and that patients should be vigorously encouraged to attend CRET following major CHD events.

The present study investigated the effect of a 9-month physical activity (PA) intervention on children's cardiorespiratory fitness levels and neuroelectric indices of conflict monitoring (i.e., error-related negativity, ERN). Four hundred twenty-eight preadolescent children (8-9 years old) were randomized into a PA intervention or wait-list control group, and completed a fitness and cognitive control assessment (i.e., modified flanker task) at pre- and posttest. Following exclusion criterion, 308 children were included in the analyses (PA intervention: n = 139; wait-list control: n = 169). Children in the intervention displayed greater improvements in fitness and response accuracy, which were accompanied by stability of ERN amplitude from pre- to posttest. In contrast, the control group revealed increased ERN amplitude at posttest compared to pretest, despite no change in fitness or task performance. These findings demonstrate the efficacy of daily PA for promoting children's fitness and underlying neural processes associated with effective conflict monitoring. Such findings have significant implications for promoting organized PA programs intended to foster overall physical and brain health in school age children. © 2017 Society for Psychophysiological Research.

Indonesia is currently facing double burden malnutrition in children. As overweight and obesity are due to a disturbed energy balance, this study aimed to assess the association of total energy intake and physical activity with the prevalence of overweight among Indonesian children. The data used for this analysis were from 1143 children, 6-12 years old, that participated in the South East Asian Nutrition Survey (SEANUTS). Physical activity (PA) was measured using pedometers for 2 consecutive days and was categorized low, moderate and high. Child nutritional status was categorized based on body mass index for age z-scores (BAZ) into normal weight (-2 SD ≤BAZ≤1 SD) or overweight (BAZ >1 SD). Energy intake was calculated from a one day 24 hour recall and compared to the Indonesian recommended dietary allowance (RDA) for energy. Children with low PA had higher risk (ODDs 3.4, 95% CI: 2.0, 6.0) of being overweight compared to children who had high PA. Children with moderate PA and energy take >100% RDA had higher risk (ODDs 4.2, 95% CI 1.9, 9.3) of being overweight than children with high PA and energy intakes ≤100% RDA. Low physical activity independently or moderate physical activity and high energy intake are risk factors for Indonesian children to get overweight. Program intervention such as increasing physical activity at school and home is needed to reduce overweight among children.

We aimed to evaluate the potential benefits of the Leadership and Coaching for Health (LEACH) program on physical activity (PA), dietary habits, and distress management in cancer survivors. We randomly assigned 248 cancer survivors with an allocation ratio of two-to-one to the LEACH program (LP) group, coached by long-term survivors, or the usual care (UC) group. At baseline, 3, 6, and 12 months, we used PA scores, the intake of vegetables and fruits (VF), and the Post Traumatic Growth Inventory (PTGI) as primary outcomes and, for secondary outcomes, the Ten Rules for Highly Effective Health Behavior adhered to and quality of life (QOL), the Hospital Anxiety and Depression Scale (HADS), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). For primary outcomes, the two groups did not significantly differ in PA scores or VF intake but differed marginally in PTGI. For secondary outcomes, the LP group showed a significantly greater improvement in the HADS anxiety score, the social functioning score, and the appetite loss and financial difficulties scores of the EORTC QLQ-C30 scales from baseline to 3 months. From baseline to 12 months, the LP group showed a significantly greater decrease in the EORTC QLQ-C30 fatigue score and a significantly greater increase in the number of the Ten Rules for Highly Effective Health Behavior. Our findings indicate that the LEACH program, coached by long-term survivors, can provide effective management of the QOL of cancer survivors but not of their PA or dietary habits.

Physical activity (PA) interventions constitute a critical component of cardiovascular disease (CVD) risk reduction programs. Objective mobile health (mHealth) software applications (apps) and wearable activity monitors (WAMs) can advance both assessment and integration of PA counseling in clinical settings and support community-based PA interventions. The use of mHealth technology for CVD risk reduction is promising, but integration into routine clinical care and population health management has proven challenging. The increasing diversity of available technologies and the lack of a comprehensive guiding framework are key barriers for standardizing data collection and integration. This paper reviews the validity, utility and feasibility of implementing mHealth technology in clinical settings and proposes an organizational framework to support PA assessment, counseling and referrals to community resources for CVD risk reduction interventions. This integration framework can be adapted to different clinical population needs. It should also be refined as technologies and regulations advance under an evolving health care system landscape in the United States and globally. PMID:26923067

To determine whether moderate-intensity physical activity (PA) and health education (HE) are differentially associated with categories of hospitalizations or subgroups of participants. Multicenter randomized controlled trial in which participants were randomized to a PA or HE program for an average of 2.6 years. Eight field centers. Sedentary men and women aged 70-89 with lower extremity physical limitations but able to walk 400-m in 15 minutes or less (N = 1,635). Structured, moderate-intensity PA (n =  818) at a center (2×/wk) and at home (3-4×/wk) that included aerobic, strength, balance, and flexibility training or HE (n =  817) of educational workshops and upper extremity stretching exercises. All-cause inpatient hospitalizations ascertained at 6-month intervals. There were 1,458 hospitalizations (49.1% of PA, 44.4% of HE; risk difference = 4.68%, 95% confidence interval (CI) = -0.18-9.54; hazard ratio (HR) = 1.16, 95% CI = 1.00-1.34). The intervention effect on incident hospitalization did not differ according to race, sex, Short Physical Performance Battery score, age, or history of cardiovascular disease or diabetes mellitus. PA was associated with higher rates of hospitalization in the middle baseline gait speed category, than HE (<0.8 m/s: HR = 0.93, 95% CI = 0.76-1.14; 0.8-1.0 m/s: HR = 1.54, 95% CI = 1.23-1.94; >1.0 m/s: HR = 1.05, 95% CI = 0.67-1.65; interaction P = .005). A PA program in older adults at risk for mobility disability did not lead to a different risk of specific types of hospitalizations than a HE program overall. Baseline gait speed may be a marker for risk of hospitalization during a PA intervention, because individuals with moderate baseline gait speed in the PA group had slightly higher rates of hospitalization than those in the HE group.

Individual, social and environmental factors influencing physical activity levels and behaviours of multiethnic socio-economically disadvantaged urban mothers in Canada: A mixed methods approach

PubMed Central

2012-01-01

Background Existing data provide little insight into the physical activity context of multiethnic socio-economically disadvantaged mothers in Canada. Our primary objectives were: (1) to use focus group methodology to develop tools to identify the individual, social, and environmental factors influencing utilitarian and leisure time physical activities (LTPA) of multiethnic SED mothers; and (2) to use a women specific physical activity survey tool to assess psychosocial barriers and supports and to quantify individual physical activity (PA) levels of multi-ethnic SED mothers in Canada. Methods Qualitative focus group sessions were conducted in West, Central and Eastern Canada with multiethnic SED mothers (n = 6 focus groups; n = 42 SED mothers) and with health and recreation professionals (HRPs) (n = 5 focus groups; n = 25 HRPs) involved in community PA programming for multiethnic SED mothers. Administration of the women specific Kaiser Physical Activity Survey (KPAS) tool was completed by consenting SED mothers (n = 59). Results More than half of SED mothers were employed and had higher total PA scores with occupation included than unemployed mothers. However, nearly 60% of both groups were overweight or obese. Barriers to LTPA included the lack of available, affordable and accessible LTPA programs that responded to cultural and social needs. Concerns for safety, nonsupportive cultural and social norms and the winter climate were identified as key barriers to both utilitarian and LTPA. Conclusions Findings show that multiethnic SED mothers experience many barriers to utilitarian and LTPA opportunities within their communities. The varying LTPA levels among these multi-ethnic SED mothers and the occurrence of overweight and obesity suggests that current LTPA programs are likely insufficient to maintain healthy body weights.

Adults with mental illness may have specific attitudes toward physical activity (PA). To assess the PA attitudes of non-institutionalised adults with mental illness, and associations with psychological distress. Participants completed questionnaires on activity preferences (type, context and sources of support), motivators, barriers and attitudes toward personal training (PT). Relationships between responses and distress were assessed using logistic regressions. One-hundred forty-two participants completed the questionnaires. PA context preferences included activities done close to home, outdoors, with professional instruction, with people of the same ability, as part of a healthy lifestyle program and with a social component. The most commonly endorsed source of support was an exercise instructor. Most respondents had never received PT; however, PT had high acceptability. Common barriers included poor physical and mental health, and lack of money. Distress was positively associated with barriers of poor mental health, tiredness, disorganisation, exhaustion and being shy/embarrassed (p ≤ 0.001). Local outdoor walking groups that include social and healthy lifestyle components, and that are led by an exercise instructor who can provide support for overcoming barriers, may best meet PA interests of this group. PT could be an acceptable method for offering individualised support.

School is an ideal setting to promote and increase physical activity (PA) in children. However, implementation of school-based PA programmes seems difficult, in particular due to schools' focus on academic performance and a lack of involvement of school staff in program development. The potential cognitive and academic benefits of PA might increase chances of successful implementation. Therefore, the aim of this qualitative study was: (1) to explore the perceptions of teachers and principals with regard to implementation of additional PA aimed at improving cognitive and academic performance, and (2) to identify characteristics of PA programmes that according to them are feasible in daily school practice. Twenty-six face-to-face semi-structured interviews were conducted with primary school teachers (grades 5 and 6) and principals in The Netherlands, and analysed using inductive content analysis. Teachers and principals expressed their willingness to implement additional PA if it benefits learning. Time constraints appeared to be a major barrier, and strongly influenced participants' perceptions of feasible PA programmes. Teachers and principals emphasised that additional PA needs to be short, executed in the classroom, and provided in "ready-to-use" materials, i.e., that require no or little preparation time (e.g., a movie clip). Future research is needed to strengthen the evidence on the effects of PA for academic purposes, and should examine the forms of PA that are both effective as well as feasible in the school setting.

Physical activity (PA) has been shown to enhance quality of life (QOL) in older adults. Findings from these studies indicate that the relationship between PA and QOL is indirect and likely mediated by variables such as physical self-esteem, exercise self-efficacy, and affect. As PA varies greatly by age, the purpose of the current study is to extend this area of research to young adults and explore the complex relationship between PA and QOL in this target population. Data were collected via anonymous questionnaire from N = 590 undergraduate students. PA was assessed with the Godin Leisure Time Exercise Questionnaire, and QOL was assessed by the Satisfaction with Life Scale. Path analysis was used to test the relationship between PA and QOL, with mediators of exercise self-efficacy, physical self-esteem, and affect. The PA model (RMSEA = .03, CFI = .99) accounted for 25 % of the variance in QOL. PA had positive direct effects on exercise self-efficacy (β = .28, P < .001), physical self-esteem (β = .10, P < .001), positive affect (β = .10, P < .05), and negative affect (β = .08, P < .05). Physical self-esteem was found to be the most powerful mediating variable on QOL (β = .30, P < .001), followed by positive affect (β = .27, P < .001) and negative affect (β = .14, P < .001). Physical self-esteem and, to a lesser extent, positive affect emerged as integral components in the link between PA and QOL. Findings suggest that health education programs designed to promote regular PA and increase physical self-esteem may be effective in improving QOL in young adults.

To estimate the effects of physical activity (PA) and obesity on the cumulative incidence of disability on the basic activities of daily living in the elderly. Longitudinal study. We selected 2477 participants aged 65-74 years from the impact evaluation study of a non-contributory pension program in Mexico. Participants were without disability at baseline. Katz index was used to assess disability both at baseline and follow-up. PA, body mass index, and covariates were measured at baseline. After 14-months of follow-up, the cumulative incidence of disability reached 10.1%. High PA was found to reduce disability risk (OR=0.64; 95%CI [0.43-0.95]), and the association between obesity and disability was marginally significant (OR=1.36; 95%CI [0.96-1.95]). There is a need to perform a functional assessment of older adults in primary care to identify patients with functional dependence , and to promote physical activity to maintain muscle mass and thus reduce the incidence of disability.

Nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity and has been identified as the leading cause of liver disease in pediatric populations worldwide. Because cardiorespiratory fitness (CRF) is related to physical activity (PA) levels, and increased PA plays a protective role against NAFLD risk factors, the aim of this study was to analyze the association between PA and a fatty liver marker (alanine aminotransferase - ALT) in obese children and adolescents, independently of central adiposity or CRF. 131 obese children (83 girls, 7-15 year-olds) involved in a PA promotion program comprised the sample. Measurements included anthropometric and body composition evaluations (DEXA), biological measurements (venipuncture), CRF (progressive treadmill test), PA (accelerometry), and maturational stage (Tanner criteria). The associations between ALT with PA intensities, central obesity, and CRF were calculated by three different models of linear regression, adjusted for potential confounders. Level of significance was set at 95%. RESULTS: ALT was negatively associated with MVPA (β = -0.305), and CRF (β = -0.426), and positively associated with central obesity (β=.468). After adjustment for central obesity the negative and statistically significant association between ALT with MVPA (β = -0.364) and CRF (β = -0.550) still persists while a positive and significantly correlation was shown between ALT and SB (β = 0.382). Additional adjustment for CRF (Model 3) showed significant associations for all the PA intensities analyzed including light activity. PA at different intensities is associated to a fatty liver marker in obese children and adolescents, independently of central adiposity or CRF. Key points In a previous study our group observed that there might be a potential protective effect of cardiorespiratory fitness (CRF) against abnormal ALT values; Considering that CRF is related to physical activity (PA), and increased PA plays a protective role against fatty liver, we hypothesized that it might be an association between PA and fatty liver in obese youth, independently of central adiposity or CRF; No other study has investigated these associations in obese youth; Our findings stresses the fact that moderate-to-vigorous and light physical activities, as well as lower sedentary behavior, is associated with lower fatty liver marker, independent of the effect of potential mediators, such as central obesity or CRF.

Our aim was to assess the potential relationships among happiness, physical activity, and smoking initiation among undergraduate medical students in Saudi Arabia. We performed a cross-sectional study of randomly selected first- to fifth-year undergraduate medical students. Smoking initiation was defined as "ever trying smoking a cigarette, waterpipe, cigar/cigarillo, or other type of tobacco, even one or 2 puffs." The short scale Oxford Happiness Questionnaire was used to assess each student's happiness. Multivariate logistic regression analysis was performed. Of the 406 students surveyed (208 boys, 198 girls), 86 (21.1%) had initiated smoking. We found an interaction between physical activity (PA) and happiness on smoking initiation (p-interaction = .012). Among boys with low levels of PA, lower levels of happiness were associated with a greater likelihood of smoking initiation (OR = 5.8, 95%CI = 1.9 - 17.5). Also, high levels of PA increased the chance of smoking initiation among male students with high levels of happiness (OR = 5.6, 95%CI = 2.1 - 14.5). Our results suggest that young men with low levels of happiness and low levels of PA, as well as high levels of PA and high levels of happiness, may be targeted as a priority population in tobacco control intervention programs.

Due to the growing concern about antibiotic-resistant microbial infections, increasing support has been given to new drug discovery programs. A promising alternative to counter bacterial infections includes the antimicrobial peptides (AMPs), which have emerged as model molecules for rational design strategies. Here we focused on the study of Pa-MAP 1.9, a rationally designed AMP derived from the polar fish Pleuronectes americanus. Pa-MAP 1.9 was active against Gram-negative planktonic bacteria and biofilms, without being cytotoxic to mammalian cells. By using AFM, leakage assays, CD spectroscopy and in silico tools, we found that Pa-MAP 1.9 may be acting both on intracellular targets and on the bacterial surface, also being more efficient at interacting with anionic LUVs mimicking Gram-negative bacterial surface, where this peptide adopts α-helical conformations, than cholesterol-enriched LUVs mimicking mammalian cells. Thus, as bacteria present varied physiological features that favor antibiotic-resistance, Pa-MAP 1.9 could be a promising candidate in the development of tools against infections caused by pathogenic bacteria.

A Joyful Heart is Good Medicine: Positive Affect Predicts Memory Complaints.

Positive affect (PA) systematically improves cognitive performance on a wide range of cognitive tasks, but the link between PA and subjective memory complaints (SMCs) is unclear. The aim of this study was to investigate the associations between PA (level and change) and SMCs over a 10-year span. Current data included participants who completed all measures in the Midlife in the US Study (N = 2,214; age range: 50-84 years; mean: 62.81; standard deviation [SD]: 8.98). The level (mean of Time 1 and Time 2) and change (Time 2 minus Time 1) of PA was examined longitudinally to determine if PA predicts SMCs. The long-term level and change of PA predicted SMCs. No age and education differences were found for the effects of PA (PA × age and PA × education) on SMCs. Additional comparison analysis found high PA (+1 SD) differs from low PA (-1 SD) on age, financial condition and depression, and physical activity. This study provides longitudinal evidence that further supports PA is associated with a key cognitive aging outcome, SMCs. Effective cognitive-health programs may need to pay more attention to PA intervention. Copyright © 2016 American Association for Geriatric Psychiatry. Published by Elsevier Inc. All rights reserved.

Proper levels of physical activity (PA) are important to healthy aging. Little is known about racial differences in influences of neighborhood perceptions (NP) on PA and use of neighborhood resources among community-dwelling older women. In 2014 and 2015, 49 white and 44 black women of age 65 and older living in Washington, DC were queried about their PA, NP, use of neighborhood resources and sociodemographic characteristics. They wore an accelerometer and a Global Positioning System device concurrently for 7 consecutive days. Data were analyzed by race. Compared to Whites, Blacks had lower NP scores (71% positive vs. 77%, p = 0.01), lower mean daily step counts (mean (SD): 3256 (1918) vs. 5457 (2989), p < 0.001), and lower frequencies of all exercise activities combined (19.7 (8.7) vs. 25.2 (11.8) per week, p = 0.01). For both Whites and Blacks, better NPs were associated with more frequent PA both at ( p = 0.05) and away from home ( p = 0.01). However, better NPs were associated with higher frequencies of exercise activities, moderate-to-high intensity activities, and utilitarian walking for Whites but not Blacks ( p < 0.05 for race-perception interaction terms). In an urban setting, older Black women were more likely than older White women to have poor NPs, less PA, and weaker or no association of positive NPs with higher levels of certain PAs. Such substantial racial differences warrant further investigation and consideration in health promotion programs.

There is evidence that physical activity (PA) is of cognitive benefit to the ageing brain, but little is known on the effect in patients with Alzheimer's disease (AD). The present pilot study assessed the effect of a home-based PA training on clinical symptoms, functional abilities, and caregiver burden after 12 and 24 weeks. In an RCT thirty patients (aged 72.4±4.3 years) with AD (MMSE: 20.6±6.5 points) and their family caregivers were allocated to a home-based 12-week PA intervention program or the usual care group. The program changed between passive, motor-assisted or active resistive leg training and changes in direction on a movement trainer in order to combine physical and cognitive stimuli. Analysis of activities of daily living in the patients (ADCS ADL total score) revealed a significant group × time interaction effect (95% CI of the difference between both groups at T2: 5.01-10.51). The control group experienced decreases in ADL performance at week 12 and 24 whereas patients in the intervention group remained stable. Analyses of executive function and language ability revealed considerable effects for semantic word fluency with a group × time interaction (95% CI of the difference between both groups at T2: 0.18-4.02). Patients in the intervention group improved during the intervention and returned to initial performance at week 12 whereas the controls revealed continuous worsening. Analyses of reaction time, hand-eye quickness and attention revealed improvement only in the intervention group. Caregiver burden remained stable in the intervention group but worsened in the control group. This study suggests that PA in a home-based setting might be an effective and intrinsically attractive way to promote PA training in AD and modulate caregiver burden. The results demonstrate transfer benefits to ADL, cognitive and physical skill in patients with AD. ClinicalTrials.gov NCT02196545.

Palmitic acid (PA) is known to cause cardiomyocyte dysfunction. Cardiac hypertrophy is one of the important pathological features of PA-induced lipotoxicity, but the mechanism by which PA induces cardiomyocyte hypertrophy is still unclear. Therefore, our study was to test whether necroptosis, a receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3-) dependent programmed necrosis, was involved in the PA-induced cardiomyocyte hypertrophy. We used the PA-treated primary neonatal rat cardiac myocytes (NCMs) or H9c2 cells to study lipotoxicity. Our results demonstrated that cardiomyocyte hypertrophy was induced by PA treatment, determined by upregulation of hypertrophic marker genes and cell surface area enlargement. Upon PA treatment, the expression of RIPK1 and RIPK3 was increased. Pretreatment with the RIPK1 inhibitor necrostatin-1 (Nec-1), the PA-induced cardiomyocyte hypertrophy, was attenuated. Knockdown of RIPK1 or RIPK3 by siRNA suppressed the PA-induced myocardial hypertrophy. Moreover, a crosstalk between necroptosis and endoplasmic reticulum (ER) stress was observed in PA-treated cardiomyocytes. Inhibition of RIPK1 with Nec-1, phosphorylation level of AKT (Ser473), and mTOR (Ser2481) was significantly reduced in PA-treated cardiomyocytes. In conclusion, RIPKs-dependent necroptosis might be crucial in PA-induced myocardial hypertrophy. Activation of mTOR may mediate the effect of necroptosis in cardiomyocyte hypertrophy induced by PA.

Lack of physical activity participation has been identified as a determinant for negative health outcomes across various ethnicities worldwide and within the USA. We investigated the perceptions of the prospects of promoting dancing within hometown associations as a form for improving physical activity participation for Nigerian Transnational Immigrants (NTIs) in the USA: a migrant cohort subset of individuals who maintain cross-border ties with their indigenous communities of origin. Using PEN-3 cultural model, we conducted semi-structured interviews with 24 transnational African migrants (11 males and 13 females) living in Chicago to explore culturally sensitive strategies to promote physical activity participation among our target population. The findings revealed positive perceptions related to dancing that might help to promote physical activity (PA) among NTI, existential or unique perceptions related to Nigerian parties that may also play a role with PA promotion, and negative perception in the form of limited discussions about PA in Nigerian hometown associations in the USA. Results from this study highlight the need for further investigation on culturally sensitive strategies to improve physical activity and participation in diverse Black immigrant populations, specifically in the form of cultural dance and activities such as parties in which this population frequently participate in. Furthermore, hometown associations may also serve as a platform for the implementation of PA programs due to its large reach to a rather covert group.

To evaluate the short-term efficacy of coach education on basketball players' physical activity (PA) intensity during practices. Intervention effects on players' motivation were also investigated. Randomized controlled trial. This study took place over the course of a 5-day organized youth sport (OYS) basketball program in 2 sports centres in Greater Western Sydney, Australia (September, 2013). A convenience sample of 76 players and 8 coaches were recruited. Players were girls aged 9 to 12 years. Following the first 2 days of the basketball program, coaches allocated into the intervention condition attended 2 coach education sessions where strategies to increase moderate-to-vigorous physical activity (MVPA) and decrease inactivity were discussed. Each coach education session lasted approximately 2h. Compared to the control group, players in the intervention group spent a significantly higher proportion of practice time in MVPA (mean difference [MD]=14.6%; standard error [SE]=2.2%), vigorous PA (VPA; MD=12.6%; SE=1.9%), moderate PA (MD=2.0%; SE=0.5%) and a significantly lower proportion of practice time inactive (MD=-14.5%; SE=2.3%) from baseline to follow-up. There were no significant changes in motivation from baseline to follow-up in either group. Brief coach education sessions can increase MVPA and decrease inactivity without deleterious effects on players' motivation. Also, substantial increases in VPA were found, which is an important finding because VPA has been associated with health benefits, over and above benefits accrued from lower-intensity activity.

Most schools have not fully implemented wellness policies, and those that have rarely incorporate meaningful student participation. The aim of the Fuel Up to Play 60 (FUTP60) program is to help schools implement wellness policies by engaging students in activities to improve access to healthful, good tasting food and drinks, and increase the number and type of opportunities for students to be physically active. The aim of this paper is to present initial student-level results from an implementation of FUTP60 in 72 schools, grades 6-9. The study used a non-controlled pretest/posttest with serial cross-sectional data. School process data and student-level data were collected in fall 2009 (pre-intervention) and spring 2010 (post-intervention). School wellness practices were captured during a baseline needs assessment survey. Validated self-administered questionnaires assessing dietary and physical activity (PA) behaviors were administered to students in grades 6-9 in the 72 pilot schools. Mixed-effects logistic regression controlling for clustering of schools and demographics was used to calculate odds ratios and confidence intervals to evaluate changes pre- and post- intervention. All 72 schools implemented FUTP60 during the 2009-2010 school year. Action strategies most frequently chosen by the schools included increasing breakfast participation and new activities before and after school. Positive and significant changes in students' behaviors (n = 32,482 at pretest and 29,839 at post-test) were noted for dairy, whole grains, fruit, and vegetable consumption and PA levels pre- and post-intervention (OR 1.05 to 1.27). Students aware of the program at post-test were significantly more likely to report healthier eating and PA behaviors than students unaware of the program (OR 1.1 to 1.34). FUTP60 pilot findings indicate that a low intensity program focused on wellness policy implementation is associated with small positive changes in student behaviors, especially when students were aware of the program. Although these initial results are promising, a more rigorous controlled study is warranted as a next step.

It is critical to employ accurate measures when assessing physical activity (PA) barriers in any subpopulation, yet existing measures are not appropriate for persons with blindness or visual impairment (PBVI) due to a lack of validity or reliability evidence. To develop and calibrate a PA barrier scale for PBVI. An expert panel (n = 3) and 18 PBVI were recruited to establish content validity for a PA barriers subscale; 160 PBVI (96 females) completed the scale along with the Physical Activity Scale for Individuals with Physical Disabilities for calibration. To establish construct-related validity evidence, Confirmative factor analysis (CFA) and Rasch analysis were applied. To investigate internal consistency and reliability, Cronbach's alpha and the reliability coefficient (R) were employed, respectively. Following CFA and Rasch analyses, five items were eliminated due to misfits; reliability coefficients were unchanged upon deletion of these items. The barriers perceived by PBVI to have the most negative impact on PA included "lack of self-discipline" (logit = 1.40) and "lack of motivation" (logit = 1.27). "Too many stairs in the exercise facility" (logit = -1.49) was perceived to have the least impact. The newly-developed scale was found to be a valid and reliable tool for evaluating PA barriers in PBVI. To enhance promotion of health-producing levels of PA in PBVI, practitioners should consider applying this new tool as a precursor to programs aimed at improving PA participation in this group.

Transport systems can play an important role in increasing physical activity (PA). Bogotá has been recognized for its bus rapid transit (BRT) system, TransMilenio (TM). To date, BRTs have been implemented in over 160 cities worldwide. The aim of this study was to assess the association between PA and the use of TM among adults in Bogotá. The study consists of a cross-sectional study conducted from 2010 to 2011 with 1000 adults. PA was measured using the International Physical Activity Questionnaire. In a subsample of 250 adults, PA was objectively measured using ActiGraph accelerometers. Analyses were conducted using multilevel logistic regression models. The use of TM was associated with meeting moderate-to-vigorous PA (MVPA). TM users were more likely to complete an average of >22 min a day of MVPA (odds ratio [OR] = 3.1, confidence interval [CI] = 95 % 1.4-7.1) and to walk for transportation for ≥150 min per week (OR = 1.5; CI = 95 % 1.1-2.0). The use of TM was associated with 12 or more minutes of MVPA (95 % CI 4.5-19.4, p < 0.0001). Associations between meeting PA recommendations and use of TM did not differ by socioeconomic status (p value = 0.106) or sex (p value = 0.288). The use of TM is a promising strategy for enhancing public health efforts to reduce physical inactivity through walking for transport. Given the expansion of BRTs, these results could inform the development of transport PA programs in low- to high-income countries.

Physical activity (PA) professionals and participants recognize enhanced quality of life (QoL) as a benefit of and motivator for PA. However, QoL measures are often problematic and rarely consider the participants'perspective. This paper focuses on recent findings from a larger project on the role of QoL in PA and health promotion. More specifically, we focus on the views of participants and potential participants to better understand the relationship of PA and QoL. In earlier stages of the project we began with a conceptual model of QoL and developed a survey. We now focus on participants' views and ask two questions: 1) what is QoL? and 2) how does PA relate to QoL? We first asked those questions of a large sample of university students and community participants as open-ended survey items, and then asked focus groups of community participants. Overall, participants' responses reflected the multidimensional, integrative QoL model, but the responses and patterns provided information that may not be picked up with typical survey measures. Findings suggest that PA contributes to multiple aspects of QoL, that social and emotional benefits are primary motivators and outcomes for participants, and that the meaning of QoL and PA benefits is subjective and contextualized, varying across individuals and settings. Programs that directly target and highlight the multiple dimensions and integrative QoL, while considering the individual participants and contexts, may enhance both PA motivation and participants' health and QoL.

Key modifiable risk behaviors such as smoking, poor diet and physical inactivity often cluster and may have multiplicative adverse effects on health. This study investigated barriers and facilitators to healthy eating and physical activity (PA) in overweight Mexican-origin smokers to inform the adaptation of an evidence-based smoking cessation program into a multiple health behavior change intervention. Five focus groups were conducted with overweight Mexican-origin men (n = 9) and women (n = 21) who smoked. Barriers and facilitators of healthy eating and PA were identified, and gender differences were assessed. Participants expressed some motivation to eat healthfully and identified strategies for doing so, yet many women experienced difficulties related to personal, family and work-related circumstances. Barriers to healthy eating among men were related to food preferences and lack of familiarity with fruits and vegetables. Participants performed PA primarily within the context of work and domestic responsibilities. Stress/depressed mood, lack of motivation and concern for physical well-being limited further PA engagement. Routines involving eating, PA and smoking highlight how these behaviors may be intertwined. Findings emphasize the importance of social, structural and cultural contexts and call for additional investigation into how to integrate healthy eating and PA into smoking cessation interventions for overweight Mexican-origin smokers.

Objective Joint use policies (JUP) encourage shared facility use, usually between schools and a city or private organization, for both physical activity-related and non-physical activity-related programs. Little is known about JUP’s impact on physical activity (PA). This study examined whether more specific JUPs were associated with increased PA and decreased sedentary behavior (SB) in adolescents. Methods Data on PA, sports participation, and SB were taken from annual cross-sectional nationally representative samples of 51,269 8th, 10th and 12th grade public school students nested in 461 school districts in the US from 2009–2011. JUP measures were constructed using information obtained from corresponding school district JU policies. Multivariable analyses were conducted, controlling for individual demographic and socioeconomic characteristics and clustering at the district level. Results Results showed small associations between more specific JUPs and increased PA (IRR 1.01, 95% CI: 1.00, 1.02). Closer examination of specific JUP provisions indicates that specifying what times facilities are available for use was associated with vigorous exercise and prioritizing school or affiliated organizations’ use and which spaces were available for use were associated with vigorous exercise and more frequent PA participation, which includes participation in sports or athletics. No associations were found between more specific JUPs and SB. Conclusions JUPS may have small influences on adolescent physical activity behavior. Future longitudinal studies should be conducted to examine the impact of JUPs in conjunction with other physical activity-related policies and environmental changes to determine what impact they have on overall adolescent physical activity and sedentary behavior.

FY2016 ILAW Glass Corrosion Testing with the Single-Pass Flow-Through Method

DOE Office of Scientific and Technical Information (OSTI.GOV)

Neeway, James J.; Asmussen, Robert M.; Parruzot, Benjamin PG

The inventory of immobilized low-activity waste (ILAW) produced at the Hanford Tank Waste Treatment and Immobilization Plant (WTP) will be disposed of at the near-surface, on-site Integrated Disposal Facility (IDF). When groundwater comes into contact with the waste form, the glass will corrode and radionuclides will be released into the near-field environment. Because the release of the radionuclides is dependent on the dissolution rate of the glass, it is important that the performance assessment (PA) model accounts for the dissolution rate of the glass as a function of various chemical conditions. To accomplish this, an IDF PA model based onmore » Transition State Theory (TST) can be employed. The model is able to account for changes in temperature, exposed surface area, and pH of the contacting solution as well as the effect of silicon concentrations in solution, specifically the activity of orthosilicic acid (H4SiO4), whose concentration is directly linked to the glass dissolution rate. In addition, the IDF PA model accounts for the alkali-ion exchange process as sodium is leached from the glass and into solution. The effect of temperature, pH, H4SiO4 activity, and the rate of ion-exchange can be parameterized and implemented directly into the PA rate law model. The rate law parameters are derived from laboratory tests with the single-pass flow-through (SPFT) method. To date, rate law parameters have been determined for seven ILAW glass compositions, thus additional rate law parameters on a wider range of compositions will supplement the existing body of data for PA maintenance activities. The data provided in this report can be used by ILAW glass scientists to further the understanding of ILAW glass behavior, by IDF PA modelers to use the rate law parameters in PA modeling efforts, and by Department of Energy (DOE) contractors and decision makers as they assess the IDF PA program.« less

mHealth programs offer potential for practical and cost-effective delivery of interventions capable of reaching many individuals. To (1) compare the effectiveness of mHealth interventions to promote physical activity (PA) and reduce sedentary behavior (SB) in free-living young people and adults with a comparator exposed to usual care/minimal intervention; (2) determine whether, and to what extent, such interventions affect PA and SB levels and (3) use the taxonomy of behavior change techniques (BCTs) to describe intervention characteristics. A systematic review and meta-analysis following PRISMA guidelines was undertaken to identify randomized controlled trials (RCTs) comparing mHealth interventions with usual or minimal care among individuals free from conditions that could limit PA. Total PA, moderate-to-vigorous intensity physical activity (MVPA), walking and SB outcomes were extracted. Intervention content was independently coded following the 93-item taxonomy of BCTs. Twenty-one RCTs (1701 participants-700 with objectively measured PA) met eligibility criteria. SB decreased more following mHealth interventions than after usual care (standardised mean difference (SMD) -0.26, 95 % confidence interval (CI) -0.53 to -0.00). Summary effects across studies were small to moderate and non-significant for total PA (SMD 0.14, 95 % CI -0.12 to 0.41); MVPA (SMD 0.37, 95 % CI -0.03 to 0.77); and walking (SMD 0.14, 95 % CI -0.01 to 0.29). BCTs were employed more frequently in intervention (mean = 6.9, range 2 to 12) than in comparator conditions (mean = 3.1, range 0 to 10). Of all BCTs, only 31 were employed in intervention conditions. Current mHealth interventions have small effects on PA/SB. Technological advancements will enable more comprehensive, interactive and responsive intervention delivery. Future mHealth PA studies should ensure that all the active ingredients of the intervention are reported in sufficient detail.

Introduction: Physically active (PA) people have a lower risk of various diseases, compared to those with sedentary lifestyles. Evidence on the effects of PA promoting programs in the workplace is large, and several systematic reviews (SR) and/or meta-analyses (MA) have been published. However, they have failed to consider factors that could influence interventions. This paper aimed to classify and describe interventions to promote PA in the workplace based on evidence from SR/MA. Method: A literature search for SR/MA was done using PubMed, Web of Science, and Science Direct (January 2006-February 2015). Quality assessment of SR/MA was performed using AMSTAR. The PRECEDE-PROCEED model was used for classifying the interventions into predisposing, enabling, reinforcing, environment, and policy domains of focus. Results: Eleven SR/MA included 220 primary studies, of which 139 (63%) were randomized controlled trials. Of 48 interventions identified, 22 (46%) and 17 (35%) focused on predisposing or enabling employees to have more PA, respectively. Of the 22 predisposing factors, 6 were information delivery, 5 were self-motivation, and 11 were program training. The enabling approaches were 12 instrument resources and 5 health service facilities. The reinforcing approaches were 4 incentive and 3 social support. The remaining interventions focused on the environmental development and policy regulation. Conclusions: This systematic meta-review classified interventions using appropriate framework and described the intervention pattern. PMID:28740029

Objective To determine the physical activity (PA) behavior, needs and preferences for underserved, ethnically diverse women with a history of endometrial cancer (EC). Methods Women with a history of EC (41 non-Hispanic black, 40 non-Hispanic white, and 18 Hispanic) completed a needs assessment during their regular follow-up appointments at Montefiore Medical Center in Bronx, NY, USA. An 8-week pilot PA intervention based on the results of the needs assessment was conducted with 5 EC survivors. Results Mean body mass index (BMI) among the 99 respondents was 34.1±7.6 kg/m2, and 66% did not exercise regularly. Self-described weight status was significantly lower than actual BMI category (p<0.001). Of the 86% who were interested in joining an exercise program, 95% were willing to attend at least once weekly. The primary motivations were improving health, losing weight, and feeling better physically. Despite the high interest in participation, volunteer rate was very low (8%). However, adherence to the 8-week pilot PA intervention was high (83%), and there were no adverse events. Body weight decreased in all pilot participants. Conclusion These data show that ethnically diverse EC survivors have a great need for, and are highly interested in, PA interventions. However, greater care needs to be taken to assess and identify barriers to increase participation in such programs. PMID:25872894

Less than half of American children meet national physical activity (PA) recommendations. This study tested the feasibility, acceptability, and preliminary effectiveness of using wearable PA monitors to increase PA in school-age children. In Phase 1 of this study, conducted in 2014, 32 fifth-grade students enrolled in a low-resource middle school were given a waist-worn Fitbit Zip monitor for 4 weeks to test its feasibility (adherence) and acceptability. Adherence, wear time of ≥8 hours per day, was examined. Feedback was solicited from parents through structured interviews. In Phase 2 , conducted in 2015, 42 sixth-grade students were assigned, by classroom, to one of three conditions (Fitbit + goal and incentive-based intervention, Fitbit only, or control) to test the feasibility of the wrist-worn Fitbit Charge and its preliminary effectiveness in increasing PA over 6 weeks. In Phase 1 , average adherence was 64.1%. In Phase 2 , it was 73.4% and 80.2% for participants in the Fitbit + intervention and Fitbit only groups, respectively ( p = .07). After controlling for baseline values, weight status, and sex, there were no significant group differences in changes in MVPA or steps from baseline to follow-up. While moderately acceptable, wearable PA monitors did not increase PA levels in this sample. They may be more effective within a coordinated school-based physical activity program.

In developed societies levels of daily physical activity (PA) among school-age children are decreasing. This implies risk factors for cardiovascular and metabolic diseases. Specific strategies to improve levels of PA are needed. In prepubertal boys there is evidence that strength training increases spontaneous PA outside of training. A total of 102 schoolchildren (age 10-14 years) in Switzerland were randomly assigned to physical education classes or to participate twice weekly at a guided strength training program for 19 weeks. Spontaneous PA energy expenditure (PAEE; 3axial accelerometry for 7 days), leg and arm strength, and body composition (dual energy radiograph absorptiometry) were measured at baseline, after 19 weeks of training intervention, and after 3 months of washout. There were no significant differences between the groups at baseline. In the intervention group, PAEE increased by 10% from baseline to end of training in boys (P = .02), but not in girls. Leg and arm strength were increased owing to training intervention in both boys and girls. All other variables were unchanged. Baseline PAEE was significantly negatively correlated with changes of PAEE. Targeted strength training significantly increases daily spontaneous PA behavior in boys. The less active children showed the greatest increase in spontaneous PAEE. Girls showed a similar increase in strength, but not in spontaneous PAEE. This may be explained by their earlier pubertal development. Strength training may be a promising strategy in schools to counteract decreasing levels of PA.

To determine if sarcopenia modulates the response to a physical activity intervention in functionally limited older adults. Secondary analysis of a randomized controlled trial. Three academic centers. Elders aged 70 to 89 years at risk for mobility disability who underwent dual-energy x-ray absorptiometry (DXA) for body composition at enrollment and follow-up at twelve months (N = 177). Subjects participated in a physical activity program (PA) featuring aerobic, strength, balance, and flexibility training, or a successful aging (SA) educational program about healthy aging. Sarcopenia as determined by measuring appendicular lean mass and adjusting for height and total body fat mass (residuals method), Short Physical Performance Battery score (SPPB), and gait speed determined on 400 meter course. At twelve months, sarcopenic and non-sarcopenic subjects in PA tended to have higher mean SPPB scores (8.7±0.5 and 8.7±0.2 points) compared to sarcopenic and non-sarcopenic subjects in SA (8.3±0.5 and 8.4±0.2 points, p = 0.24 and 0.10), although the differences were not statistically significant. At twelve months, faster mean gait speeds were observed in PA: 0.93±0.4 and 0.95±0.03 meters/second in sarcopenic and non-sarcopenic PA subjects, and 0.89±0.4 and 0.91±0.03 meters/second in sarcopenic and non-sarcopenic SA subjects (p = 0.98 and 0.26), although not statistically significant. There was no difference between the sarcopenic and non-sarcopenic groups in intervention adherence or number of adverse events. These data suggest that older adults with sarcopenia, who represent a vulnerable segment of the elder population, are capable of improvements in physical performance after a physical activity intervention.

Few prospective cohort studies have examined the association between physical activity (PA) and insomnia prevention, and the effective PA intensity remains unclear. This prospective study explores how PA intensity prevents incident short sleep duration and subjective insufficient sleep in middle-aged and older adults. A self-reported questionnaire gathered data on sleep and PA variables, including moderate low-intensity PA (MLPA); moderate high-intensity PA (MHPA); and vigorous-intensity PA (VPA), during health checkups conducted in Meiji Yasuda Shinjuku Medical Center in Tokyo. This study followed two cohorts from a 2008 baseline survey: (1) participants free of short sleep duration (n=7,061) and (2) participants free of insufficient sleep (n=7,385). They were divided into middle-aged (<60 years; 45.7 [8.8] years for sleep duration and 45.5 [8.8] years for sleep sufficiency) and older adults (both groups aged 65.3 [4.7] years) and followed for a mean 3.4 years until 2013. Data were analyzed in 2014. Engaging in MHPA (hazard ratio [HR]=0.81, 95% CI=0.67, 0.98) and VPA (HR=0.83, 95% CI=0.71, 0.97) had a significant preventive effect on incident subjective insufficient sleep among middle-aged adults. For older adults, only MLPA (HR=0.58, 95% CI=0.42, 0.81) had a significant preventive effect on incident insufficient sleep, and PA did not significantly affect incident short sleep duration. Middle-aged adults engaging in MHPA and VPA and older adults engaging in MLPA can effectively maintain sleep sufficiency. When providing an effective PA program to prevent insomnia, the intensity of PA should correspond to the participant's age. Copyright © 2015 American Journal of Preventive Medicine.

Physical activity (PA) may be important for preventing chronic diseases for adolescent and young adult (AYA) childhood cancer survivors. Randomized controlled trials (RCTs) of PA interventions for AYA survivors are sparse, but necessary to determine effective programs for increasing PA among this population. Thus, we conducted a pilot RCT, testing the feasibility of a mobile health (mHealth) intervention to promote PA among AYA survivors. We recruited 14- to 18-year-olds who were ≥1-year post cancer therapy from Seattle Children's Hospital. The 10-week intervention consisted of a wearable PA-tracking device (Fitbit Flex) and a peer-based virtual support group (Facebook group). Research staff helped set step goals and awarded badges weekly. Controls received usual care. Baseline assessments occurred before randomization and follow-up assessments occurred during weeks 8-10 of the intervention period. Feasibility criteria are defined below. Qualitative interviews assessed acceptability. Exploratory outcomes included PA, quality of life, and motivation for PA. All feasibility criteria were met: we recruited 60 survivors, intervention participants wore the Fitbit on the majority (71.5%) of intervention days, and ≥90% of all participants completed questionnaires. Qualitative data confirmed intervention acceptability. Exploratory analyses found no significant adjusted group differences for change in moderate-to-vigorous PA (4.4 vs. 5.0 min/day; P = 0.92) or sedentary time (-4.5 vs. 1.0 min/day; P = 0.73), comparing intervention subjects to controls. Some modest differences were found for select subscales of quality of life and motivation for PA. This mHealth PA intervention was feasible and acceptable to AYA childhood cancer survivors and warrants a fully powered RCT. © 2017 Wiley Periodicals, Inc.

Physical activity and quality of life among university students: exploring self-efficacy, self-esteem, and affect as potential mediators

Purpose Physical activity (PA) has been shown to enhance quality of life (QOL) in older adults. Findings from these studies indicate that the relationship between PA and QOL is indirect and likely mediated by variables such as physical self-esteem, exercise self-efficacy, and affect. As PA varies greatly by age, the purpose of the current study is to extend this area of research to young adults and explore the complex relationship between PA and QOL in this target population. Methods Data were collected via anonymous questionnaire from N = 590 undergraduate students. PA was assessed with the Godin Leisure Time Exercise Questionnaire, and QOL was assessed by the Satisfaction with Life Scale. Path analysis was used to test the relationship between PA and QOL, with mediators of exercise self-efficacy, physical self-esteem, and affect. Results The PA model (RMSEA = .03, CFI = .99) accounted for 25 % of the variance in QOL. PA had positive direct effects on exercise self-efficacy (β = .28, P < .001), physical self-esteem (β = .10, P < .001), positive affect (β = .10, P < .05), and negative affect (β = .08, P < .05). Physical self-esteem was found to be the most powerful mediating variable on QOL (β = .30, P < .001), followed by positive affect (β = .27, P < .001) and negative affect (β = .14, P < .001). Conclusion Physical self-esteem and, to a lesser extent, positive affect emerged as integral components in the link between PA and QOL. Findings suggest that health education programs designed to promote regular PA and increase physical self-esteem may be effective in improving QOL in young adults. PMID:23928820

Characteristics of Teacher Training in School-Based Physical Education Interventions to Improve Fundamental Movement Skills and/or Physical Activity: A Systematic Review.

Lander, Natalie; Eather, Narelle; Morgan, Philip J; Salmon, Jo; Barnett, Lisa M

2017-01-01

Fundamental movement skill (FMS) competence is positively associated with physical activity (PA). However, levels of both FMS and PA are lower than expected. Current reviews of interventions to improve FMS and PA have shown that many school-based programs have achieved positive outcomes, yet the maintenance of these interventions is variable. Teachers play a central role in the success and longevity of school-based interventions. Despite the importance of teacher engagement, research into the nature and quality of teacher training in school-based PA and FMS interventions has received little attention. The aim of this systematic review was to investigate the type and quantity of teacher training in school-based physical education PA and/or FMS interventions, and to identify what role teacher training had on the intervention outcome. A systematic search of eight electronic databases was conducted. Publication date restrictions were not implemented in any database, and the last search was performed on 1 March 2015. School physical education-based interventions facilitated by a school teacher, and that included a quantitative assessment of FMS competence and/or PA levels were included in the review. The search identified 39 articles. Eleven of the studies measured FMS, 25 studies measured PA and three measured both FMS and PA. Nine of the studies did not report on any aspect of the teacher training conducted. Of the 30 studies that reported on teacher training, 25 reported statistically significant intervention results for FMS and/or PA. It appears that teacher training programs: are ≥ 1 day; provide comprehensive subject and pedagogy content; are framed by a theory or model; provide follow-up or ongoing support; and measure teacher satisfaction of the training, are more effective at improving student outcomes in FMS and/or PA. However, the provision of information regarding the characteristics of the teacher training was largely inadequate. Therefore, it was difficult to ascertain which teacher training characteristics were most important in relation to intervention effectiveness. It is clear that whilst teachers are capable of making substantial improvements in student outcomes in PA and FMS, the findings of this review suggest the teacher training component of school-based PA and/or FMS interventions is not only under-reported but is under-studied, and, perhaps as a result, the value of teacher training is not widely understood. What remains unclear, due to poor reporting, is what role teacher training is having on these outcomes.

Few instruments that measure physical activity (PA) can accurately quantify PA performed at light and moderate intensities, which is particularly relevant in older adults. The evidence of their reliability in free-living conditions is limited. The study objectives were: (1) to determine the test-retest reliability of the Actigraph (ACT), SenseWear Armband (SWA), and Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire in assessing free-living PA at light and moderate intensities in people after total knee arthroplasty; (2) to compare the reliability of the 3 instruments relative to each other; and (3) to determine the reliability of commonly used monitoring time frames (24 hours, waking hours, and 10 hours from awakening). A one-group, repeated-measures design was used. Participants wore the activity monitors for 2 weeks, and the CHAMPS questionnaire was completed at the end of each week. Test-retest reliability was determined by using the intraclass correlation coefficient (ICC [2,k]) to compare PA measures from one week with those from the other week. Data from 28 participants who reported similar PA during the 2 weeks were included in the analysis. The mean age of these participants was 69 years (SD=8), and 75% of them were women. Reliability ranged from moderate to excellent for the ACT (ICC=.75-.86) and was excellent for the SWA (ICC=.93-.95) and the CHAMPS questionnaire (ICC=.86-.92). The 95% confidence intervals (95% CI) of the ICCs from the SWA were the only ones within the excellent reliability range (.85-.98). The CHAMPS questionnaire showed systematic bias, with less PA being reported in week 2. The reliability of PA measures in the waking-hour time frame was comparable to that in the 24-hour time frame and reflected most PA performed during this period. Reliability may be lower for time intervals longer than 1 week. All PA measures showed good reliability. The reliability of the ACT was lower than those of the SWA and the CHAMPS questionnaire. The SWA provided more precise reliability estimates. Wearing PA monitors during waking hours provided sufficiently reliable measures and can reduce the burden on people wearing them. © 2016 American Physical Therapy Association.

Establishing a framework for a physician assistant/bioethics dual degree program.

PubMed

Carr, Mark F; Bergman, Brett A

2014-01-01

: Numerous medical schools currently offer a master of arts (MA) in bioethics dual degree for physicians. A degree in bioethics enhances the care physicians provide to patients and prepares physicians to serve on ethics committees and consult services. Additionally, they may work on institutional and public policy issues related to ethics. Several physician assistant (PA) programs currently offer a master of public health (MPH) dual degree for PAs. A degree in public health prepares PAs for leadership roles in meeting community health needs. With the success of PA/MPH dual degree programs, we argue here that a PA/bioethics dual degree would be another opportunity to advance the PA profession and consider how such a program might be implemented. The article includes the individual perspectives of the authors, one of whom completed a graduate-level certificate in bioethics concurrently with his 2-year PA program, while the other served as a bioethics program director.

The objective of this study was to determine the feasibility (i.e., limited efficacy testing, practicality, and acceptability) of a 6-week smartphone game-based applications program for promoting physical activity (PA) in adolescents in an afterschool program. This mixed-method, quasi-experimental design study included 27 adolescents who evaluated four smartphone PA game-based applications in two Boys & Girls Clubs of America. After an initial baseline week (i.e., usual activity during their visit to the Club), adolescents played each game for 1 week. During a final week, the participants could choose to play any combination of the four games. An established conceptual framework was used to assess feasibility. Efficacy was assessed by changes in PA via wrist-worn accelerometers (model GT3x+; ActiGraph LLC, Pensacola, FL). Practicality was measured through field notes, the number of players attending each session, and the proportion of attendees who played the games. Acceptability was measured using poststudy focus groups. Compared with baseline (3.22 metabolic equivalents [METs]), mean accelerometer values were significantly (P<0.05) higher during "Space Rayders" (4.33 METs) and "Color Hunt" (3.67 METs). Attendance did not differ among games, and weekly number of players averaged 12 of 27 participants. Qualitative findings indicated that participants perceived "Space Rayders" as the most acceptable game. Overall, participants found the games to be enjoyable and easy to use, although they had suggestions to improve graphics and sounds. Smartphone games can be feasible for adolescents to use for PA. Lessons learned will be used to provide improvements for future game development and evaluation.

The purpose of this study is to investigate whether an in-home, individually tailored intervention is efficacious in promoting increases in physical activity (PA) and improvements in physical functioning (PF) in low-active older adults. Participants were randomized to two groups for the 8-week intervention. The enhanced physical activity (EPA) group received individualized exercise programming, including personalized step goals and a resistance band training program, and the standard of care (SoC) group received a general activity goal. Pre- and post-intervention PF measures included choice step reaction time, knee extension/flexion strength, hand grip strength, and 8 ft up and go test completion time. Thirty-nine subjects completed this study (74.6 ± 6.4 years). Significant increases in steps/day were observed for both the EPA and SoC groups, although the improvements in the EPA group were significantly higher when including only those who adhered to weekly step goals. Both groups experienced significant PF improvements, albeit greater in the EPA group for the 8 ft up and go test and knee extension strength. A low cost, in-home intervention elicited improvements in both PA and PF. Future research is warranted to expand upon the size and scope of this study, exploring dose thresholds (and time frames) for PA to improve PF and strategies to further bolster adherence rates to maximize intervention benefits.

Besides conventional adjuvant therapies, many breast cancer survivors engage in various activities like exercise, diet and complementary and alternative medicine (CAM) in order to improve their prognosis. Little is known about specific interests and willingness to participate in institutional programs (e.g. exercise classes). We conducted a cross-sectional study in patients with early breast cancer assessing current physical activity (PA, e.g. 30 minutes brisk walking), attention to eating habits ("diet"), use of CAM, and interest in learning more about these fields. Patients indicating interest in PA counselling received a voucher for a free instruction by a certified physiotherapist. Data were analysed for factors predictive for engagement in the three fields using a stepwise multivariate logistic approach. Of 342 consecutive patients, 232 (69%) reported to be physically active more than once per week, 299 (87%) paying special attention to nutrition (in most cases fruits, "balanced diet", low fat), and 159 (46%) use of CAM (vitamins, special teas, homeopathy, herbal medicine, mistletoe). Factors predictive for PA were use of CAM, higher age, and fewer worries about the future. Swiss nationality at birth, physical activity and higher education were predictive for diet; whereas physical activity, higher education and lower age were predictive for use of CAM. No associations between any of the above variables and breast cancer characteristics were found. Around half of the patients reported interest in receiving more information and willingness to attend special counselling. Of 166 vouchers, only 7 (4%) were eventually utilized. A high proportion of breast cancer survivors report PA, following a specific diet and use of CAM. There were no disease related factors associated with such pursuits, but an association between patient related factors and these fields was observed suggesting general health awareness in some patients. Around half of the patients were interested in more information and indicated willingness to participate in institutional programs. Impact on disease specific and general health including health economic aspects warrants further research.

Bronchodilation and exercise training (ExT) improve exercise tolerance in patients with chronic obstructive pulmonary disease (COPD); however, behavior modification is required to impact on daily physical activity (PA). To assess whether tiotropium/olodaterol, ±ExT, would improve exercise endurance time (EET) and PA compared with placebo in patients participating in a self-management behavior-modification (SMBM) program. A 12-week, randomized, partially double-blind, placebo-controlled, parallel-group trial in patients with COPD (PHYSACTO®; NCT02085161). All patients were enrolled into SMBM and randomized 1:1:1:1 to once-daily placebo, tiotropium 5 µg, tiotropium/olodaterol 5/5 µg, or tiotropium/olodaterol 5/5 µg plus 8 weeks ExT. EET, measured by endurance shuttle walk test after 8 weeks, was the primary endpoint. Additional endpoints assessed downstream effects on PA (measured via accelerometry), and activity-related dyspnea and difficulty (using validated patient-reported questionnaires). SMBM + tiotropium/olodaterol, ±ExT, significantly improved EET at Week 8 versus SMBM + placebo (treatment ratio versus placebo: with ExT 1.46 [95% CI: 1.20, 1.78]; P=0.0002; without ExT 1.29 [1.06, 1.57]; P=0.0109). No significant increases in steps per day from baseline were observed over SMBM + placebo at Week 12 (increase of 1,098) when other therapies were added. Adding tiotropium/olodaterol, ±ExT, to SMBM reduced activity-related dyspnea versus placebo, while adding tiotropium/olodaterol + ExT reduced activity-related difficulty. Tiotropium/olodaterol, ±ExT, improved EET in patients with COPD taking part in an SMBM program. Combination bronchodilation, ±ExT, did not provide additional increases in objective PA compared with SMBM alone, but did reduce physical activity-related dyspnea and difficulty.

Guidelines for physical activity exist and following them would improve health. Physicians can advise patients on physical activity. We found barriers related to physicians' knowledge, a lack of tools and of physician incentives, and competing demands for limited time with a patient. We discuss interventions that could reduce these barriers. Uptake of physical activity (PA) guidelines would improve health and reduce mortality in older adults. However, physicians face barriers in guideline implementation, particularly when faced with needing to tailor recommendations in the presence of chronic disease. We performed a behavioral analysis of physician barriers to PA guideline implementation and to identify interventions. The Too Fit To Fracture physical activity recommendations were used as an example of disease-specific PA guidelines. Focus groups and semi-structured interviews were conducted with physicians and nurse practitioners in Ontario, stratified by type of physician, geographic area, and urban/rural, and transcribed verbatim. Two researchers coded data and identified emerging themes. Using the behavior change wheel framework, themes were categorized into capability, opportunity and motivation, and interventions were identified. Fifty-nine family physicians, specialists, and nurse practitioners participated. Barriers were as follows: Capability-lack of exercise knowledge or where to refer; Opportunity-pragmatic tools, fit within existing workflow, available programs that meet patients' needs, physical activity literacy and cultural practices; Motivation-lack of incentives, not in their scope of practice or professional identity, competing priorities, outcome expectancies. Interventions selected: education, environmental restructuring, enablement, persuasion. Policy categories: communications/marketing, service provision, guidelines. Key barriers to PA guideline implementation among physicians include knowledge on where to refer or what to say, access to pragmatic programs or resources, and things that influence motivation, such as competing priorities or lack of incentives. Future work will report on the development and evaluation of knowledge translation interventions informed by the barriers.

This study evaluated the effect of two home-based exercise interventions (one culturally adapted and one standard) on changes in social cognitive theory (SCT) variables, physical activity (PA), and sedentary time (ST), and determined the association between changes in SCT variables and changes in PA and ST in Hispanic breast cancer survivors. Project VIVA! was a 16-week randomized controlled pilot study to test the effectiveness and feasibility of a culturally adapted exercise intervention for Mexican American and Puerto Rican breast cancer survivors in Houston, Texas and San Juan, Puerto Rico, respectively. Women (N = 89) completed questionnaires on SCT variables, PA, and ST and were then randomized to a 16-week culturally adapted exercise program, a non-culturally adapted standard exercise intervention or a wait-list control group. Multiple regression models were used to determine associations between changes in SCT variables and changes in PA and ST. Participants were in their late 50s (58.5 ± 9.2 years) and obese (31.0 ± 6.5 kg/m 2 ). Women reported doing roughly 34.5 min/day of PA and spending over 11 h/day in sedentary activities. Across groups, women reported significant increases in exercise self-efficacy and moderate-intensity, vigorous-intensity, and total PA from baseline to follow-up (p < 0.05). Increased social support from family was associated with increases in vigorous-intensity PA. Increases in social modeling were associated with increases in moderate-intensity and total PA and with decreases in ST from baseline to follow-up (p < 0.05). Hispanic cancer survivors benefit from PA interventions that focus on increasing social support from family and friends and social modeling. Copyright © 2015 John Wiley & Sons, Ltd.

Assessment of a two-year school-based physical activity intervention among 7-9-year-old children

PubMed Central

2011-01-01

Background Physical activity (PA) in children has declined in recent decades, highlighting the need for effective intervention programs for school-aged children. The main objective of this study was to assess to what extent PA during and after school hours changed among children who received a progressive two-year long intervention vs. that of children who only received general curriculum-based PA. Methods A cluster randomized intervention study was conducted and six elementary schools randomly assigned to serve as control- or intervention schools. All children attending second grade (mean age = 7.4 years - born in 1999) were invited to participate in the fall of 2006 (N = 320, 82% participated), again in 2007 (midpoint) and 2008 (end of intervention). The intervention consisted of multi-component PA-intervention during school hours and was conducted by teachers at each intervention school. PA was assessed by means of accelerometers and subjectively at the intervention schools via teachers' PA log-books. Results There was no difference in PA intensity (minutes of moderate-to-vigorous physical activity - min of MVPA) between the two study groups at baseline, but children in the intervention schools were more physically active at moderate-to-vigorous intensity compared to those in control schools after one year of intervention (mean difference of MVPAlog-minutes: 0.61, 95%CI: 0.02, 1.20, p = 0.04). Moreover, the model for minutes of MVPA during school hours, showed a significant three-way interaction between time at mid-point, group and gender (mean difference of MVPAlog-minutes: 1.06, 95%CI: 0.15, 1.97, p = .02), indicating a significantly greater increase among the boys in the intervention schools compared to girls. No difference in PA was detected between the study groups at the end of the study period after two years of intervention. Conclusions The results suggest that the objective of increasing PA at school was met after one year of intervention, and it was more pronounced among boys. The lack of increase at the end of the study period suggested that any increase in PA during school may highly depend on both motivation and training of general teachers. Boys may respond better to PA interventions such as the one described in this study. PMID:22185086

The impact of the natural environment on the promotion of active living: an integrative systematic review.

An understanding of how the living environment influences physical activity (PA) is of great importance for health promotion. Researchers have reported increased PA when there is a greater availability of nature within people's living environment. However, little has been said about underlying motivational processes. The aim of this study was to review the existing literature on the relationship between the natural environment (NE) and PA, integrating it into a conceptual model that depicts the motivational process underlying this relationship. Through a systematic literature search in line with PRISMA guidelines, peer-reviewed articles were sought using PubMed (search updated to October 2013) and scrutiny of reference lists. In addition, we contacted experts within our network. We reviewed papers in which the research question(s) concerned: 1) Effects of PA in NE on individuals' feelings and beliefs; 2) Relationships between PA and availability of NEs; and 3) Motivational processes underlying visits to NEs in association with PA. Analysis and integration of the 90 selected studies were performed using the theory of planned behaviour (TPB). People's experiences in using the NE can enhance attitudes toward PA and perceived behavioural control via positive psychological states and stress-relieving effects, which lead to firmer intentions to engage in PA. Individual and environmental barriers, as expressions of social support and actual behavioural control, impact the process via subjective norm and perceived behavioural control. Instrumental beliefs such as a desire to enjoy nature and the expected health benefits also influence the process via attitudes. Different patterns have been identified for neighbourhood-based PA and outdoor recreations that take place in a NE. The availability of a NE and attractive views of nature within an individual's living environment are important contributors to PA, yet attention should focus on personal characteristics and environmental barriers. Policy and infrastructural interventions should aim to guarantee access and maintenance of the NE, as well as information and programming of social activities. Social campaigns via media and health institutions should highlight how nature can be a source of motivation for maintaining a PA routine, reducing stress and achieving aesthetic and health goals.

Identification of novel amino acid residues of influenza virus PA-X that are important for PA-X shutoff activity by using yeast.

The influenza A virus protein PA-X comprises an N-terminal PA region and a C-terminal PA-X-specific region. PA-X suppresses host gene expression, termed shutoff, via mRNA cleavage. Although the endonuclease active site in the N-terminal PA region of PA-X and basic amino acids in the C-terminal PA-X-specific region are known to be important for PA-X shutoff activity, other amino acids may also play a role. Here, we used yeast to identify novel amino acids of PA-X that are important for PA-X shutoff activity. Unlike wild-type PA-X, most PA-X mutants predominantly localized in the cytoplasm, indicating that these mutations decreased the shutoff activity of PA-X by affecting PA-X translocation to the nucleus. Mapping of the identified amino acids onto the N-terminal structure of PA revealed that some of them likely contribute to the formation of the endonuclease active site of PA. Copyright © 2018.

This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Texas Army National Guard (ARNG) property in Austin, Texas. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing, preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining, site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment.more » This PA satisfies, for the Bee Caves Armory property, the requirements of the Department of Defense Installation Restoration Program. Of concern is the potential for hazardous waste to be present on the property as a result of the former Nike Missile Base operations or in the form of original construction materials. Environmentally sensitive operations associated with the property from that period include (1) underground fuel storage, (2) hazardous materials storage/use, (3) disposal of hazardous waste and (4) release of hazardous waste water.« less

2014-08-01

The current study investigated key beliefs related to decisions for physical activity (PA) engagement among first-in-family (FIF) students transitioning to university. FIF students (n = 157) completed an online questionnaire assessing standard theory of planned behaviour constructs and belief-based items. One week later, participants completed a follow-up questionnaire assessing self-reported PA during the previous week. Results identified a range of behavioural, normative, and control beliefs that were significantly correlated with both PA intention and behaviour. Various key beliefs were also identified in relation to FIF students' decisions to be regularly physically active, with behavioural beliefs such as "take up too much time", normative beliefs including "friends outside of university", and control beliefs such as "cost", identified. Finally, frequencies of those who strongly or fully accepted these beliefs were analysed, demonstrating that typically, a large number of FIF students did not hold the beliefs, and as such, these are relevant to target in resultant interventions. The current study effectively highlights a number of key beliefs that can be targeted in programs aimed at encouraging FIF students' PA. Further, the study addresses a gap in the literature of targeting FIF students, a cohort at risk for inactivity, and utilises a sound theoretical framework to identify the unique set of beliefs guiding decisions for PA for this at-risk community group.

FY2017 ILAW Glass Corrosion Testing with the Single-Pass Flow-Through Method

DOE Office of Scientific and Technical Information (OSTI.GOV)

Neeway, James J.; Asmussen, Robert M.; Cordova, Elsa

The inventory of immobilized low-activity waste (ILAW) produced at the Hanford Tank Waste Treatment and Immobilization Plant (WTP) will be disposed of at the near-surface, on-site Integrated Disposal Facility (IDF). When groundwater comes into contact with the waste form, the glass will corrode and radionuclides will be released into the near-field environment. Because the release of the radionuclides is dependent on the dissolution rate of the glass, it is important that the performance assessment (PA) model accounts for the dissolution rate of the glass as a function of various conditions. To accomplish this, an IDF PA glass dissolution model basedmore » on Transition State Theory (TST) can be employed. The model is able to account for changes in temperature, exposed surface area, and pH of the contacting solution as well as the effect of silicon solution concentrations, specifically the activity of orthosilicic acid (H4SiO4), whose concentration is directly linked to the glass dissolution rate. In addition, the IDF PA model accounts for the ion exchange process. The effect of temperature, pH, H4SiO4 activity, and the rate of ion exchange can be parameterized and implemented directly into the PA rate model. The rate model parameters are derived from laboratory tests with the single-pass flow-through (SPFT) method. The provided data can be used by glass researchers to further the understanding of ILAW glass behavior, by IDF PA modelers to use the rate model parameters in PA modeling efforts, and by Department of Energy (DOE) contractors and decision makers as they assess the IDF PA program.« less

To examine associations between objectively measured physical activity (PA) and incidence of major mobility disability (MMD) and persistent MMD (PMMD) in older adults in the Lifestyle Interventions and Independence for Elders (LIFE) Study. Prospective cohort of individuals aged 65 and older undergoing structured PA intervention or health education. The LIFE Study was a multicenter (eight sites) randomized controlled trial designed to compare the efficacy of a long-term structured PA intervention with that of a health education (HE) program in reducing the incidence of MMD in mobility-limited older adults. LIFE Study participants (n = 1,590) had a mean age±standard deviation of 78.9 ± 5.2, low levels of PA, and measured mobility-relevant functional impairment at baseline. Activity data were collected using hip-worn 7-day accelerometers at baseline and 6, 12, and 24 months after randomization to test for associations with incident MMD and PMMD (≥2 consecutive instances of MMD). At baseline, every 30 minutes spent being sedentary (<100 accelerometry counts per minute) was associated with higher rate of subsequent MMD (10%) and PMMD (11%) events. Every 500 steps taken was associated with lower rate of MMD (15%) and PMMD (18%). Similar associations were observed when fitting accelerometry-based PA as a time-dependent variable. Accelerometry-based PA levels were strongly associated with MMD and PMMD events in older adults with limited mobility. These results support the importance of daily PA and lower amounts of sedentary time levels in this population and suggest that accelerometry may be a useful tool for assessing risk of mobility disability. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Ethnic minorities or those with low socioeconomic status (SES) are at increased risk of cardiovascular disease, type 2 diabetes, and all-cause mortality, compared to higher SES Whites. National surveys also indicate that low-income, ethnic minority women have the highest rates of inactivity in the United States. This study (the Increasing Motivation for Physical ACTivity or IMPACT study) promoted adoption and maintenance of physical activity (PA) in sedentary, low-income women participating in federally funded job training programs. The study consisted of 2 months of weekly 1-hr classes, then random assignment to 10 months of either home-based telephone counseling for PA plus information and feedback via mailed newsletters (Phone + Mail Counseling condition) or just the mailed newsletters (Mail Support condition). The IMPACT intervention included behavior change strategies for PA as well as discussions related to motivational readiness for PA change. Participants completed surveys and physiological assessments at baseline after the classes ended (i.e., at 10 weeks) and at 6 and 12 months postbaseline. Seventy-three percent of randomized participants (n = 72) were Latina, with a mean age of 32 +/- 10 years. More than half the women had not completed high school, and 73% had an annual income less than 20,000 dollars. After 10 months of a home-based intervention, women in the phone + mail counseling condition had significantly greater increases in estimated total energy expenditure compared to women in the mail support condition (p < .05). Regular PA counseling delivered via the telephone and through the mail appears effective for encouraging regular PA among low-income women transitioning from welfare or job training to the workforce.

Embracing a physically active lifestyle is especially important for American Indian (AI) children who are at a greater risk for hypokinetic diseases, particularly Type 2 diabetes. The purpose of this study was to describe AI children's pedometer-determined physical activity (PA) segmented into prominent daily activity patterns. Participants included 5th- and 6th-grade children (N = 77) attending school from 1 Southwestern US AI community. Children wore a pedometer (Yamax Digiwalker SW-200) for 7 consecutive days. Boys accumulated 12,621 (± 5385) steps/weekday and girls accumulated 11,640 (± 3695) steps/weekday of which 38% (4,779 ± 1271) and 35% (4,027 ± 1285) were accumulated at school for boys and girls, respectively. Physical education (PE) provided the single largest source of PA during school for both boys (25% or 3117 steps/day) and girls (23% or 2638 steps/day). Lunchtime recess provided 1612 (13%) and 1241 (11%) steps/day for boys and girls, respectively. Children were significantly less active on weekend days, accumulating 8066 ± 1959 (boys) and 6676 ± 1884 (girls). Although children accumulate a majority of their steps outside of school, this study highlights the important contribution of PE to the overall PA accumulation of children living in AI communities. Further, PA programming during the weekend appears to be important for this population.

Some prior studies have shown that racial disparities exist in intravenous tissue plasminogen activator (tPA) use for acute ischemic stroke. We sought to determine whether race was associated with tPA treatment for stroke in a predominantly black urban population. Systematic chart abstraction was performed on consecutive hospitalized patients with ischemic stroke from all 7 acute care hospitals in the District of Columbia from February 1, 2008, to January 31, 2009. Of 1044 patients with ischemic stroke, 74% were black, 19% non-Hispanic white, and 5% received intravenous tPA. Blacks were one third less likely than whites to receive intravenous tPA (3% versus 10%, P<0.001). However, blacks were also less likely than whites to present within 3 hours of symptom onset (13% versus 21%, P=0.004) and also less likely to be tPA-eligible (5% versus 13%, P<0.001). Of those who presented within 3 hours, blacks were almost half as likely to be treated with intravenous tPA than whites (27% versus 46%, P=0.023). The treatment rate for tPA-eligible patients was similar for blacks and whites (70% versus 76%, P=0.62). In this predominantly black urban population hospitalized for acute ischemic stroke, blacks were significantly less likely to be treated with intravenous tPA due to contraindications to treatment, delayed presentation, and stroke severity. Effective interventions designed to increase treatment in this population need to focus on culturally relevant education programs designed to address barriers specific to this population.

Tumor cells depend on aerobic glycolysis for adenosine triphosphate (ATP) production, which is therefore targeted by therapeutic agents. The compound 3-bromopyruvate (3-BrPA), a strong alkylating agent and hexokinase inhibitor, inhibits tumor cell glycolysis and the production of ATP, causing apoptosis. 3-BrPA induces apoptosis of nasopharyngeal carcinoma (NPC) cell lines HNE1 and CNE-2Z, which may be related to its molecular mechanisms. In the present study, we investigated the effects of 3-BrPA on the viability, reactive oxygen species (ROS), apoptosis and other types of programmed cell death in NPC cells in vitro and in vivo. PI staining showed significant apoptosis in NPC cells accompanied by the overproduction of ROS and downregulation of mitochondrial membrane potential (MMP, ΔΨm) by 3-BrPA. However, the ROS scavenger N-acetyl-L-cysteine (NAC) significantly reduced 3-BrPA-induced apoptosis by decreasing ROS and facilitating the recovery of MMP. We elucidated the molecular mechanisms underlying 3-BrPA activity and found that it caused mitochondrial dysfunction and ROS production, leading to necroptosis of NPC cells. We investigated the effects of the caspase inhibitor z-VAD-fmk, which inhibits apoptosis but promotes death domain receptor (DR)-induced NPC cell necrosis. Necrostatin-1 (Nec-1) inhibits necroptosis, apparently via a DR signaling pathway and thus abrogates the effects of z-VAD‑fmk. In addition, we demonstrated the effective attenuation of 3-BrPA-induced necrotic cell death by Nec-1. Finally, animal studies proved that 3-BrPA exhibited significant antitumor activity in nude mice. The present study is the first demonstration of 3-BrPA-induced non-apoptotic necroptosis and ROS generation in NPC cells and provides potential strategies for developing agents against apoptosis‑resistant cancers.

Many Australian young men (18-25 years) fail to meet recommendations in national dietary or physical activity (PA) guidelines. However, there is a lack of understanding of their perspectives on PA and diet to inform intervention design. This study examined young men’s motivators and barriers to healthy eating and PA, along with differences by demographic and behavioral factors. A cross-sectional online survey was completed by 282 men aged 18 to 25 years in Australia. Results identified the most common motivators for healthy eating included improving health (63.5%), body image (52.3%), and increasing energy (32.1%). Motivators for PA included improving body image (44.6%), fitness (44.2%), and health (41.0%). Common barriers to healthy eating were access to unhealthy foods (61.1%), time to cook/prepare healthy foods (55.0%), and motivation to cook healthy foods (50.7%). Barriers for PA included motivation (66.3%), time (57.8%), and cost of equipment/facilities (33.3%). Significant differences (p < .01) in motivators to healthy eating and/or PA were identified for BMI category, marital status, PA level, alcohol intake, and stress levels. Significant differences were identified for barriers to healthy eating and/or PA by BMI, PA level, stress, and fruit and vegetable intake, assessed using Pearson’s chi-square test. Findings suggest that promotion of benefits related to health, appearance/body image, increased energy and fitness, and addressing key barriers including motivation, time, financial restraints, and accessibility of unhealthy foods, could engage young men in improving lifestyle behaviors. Differences by demographic and behavioral factors suggest development of tailored programs to address diversity among young men may be required. PMID:27923963

Many Australian young men (18-25 years) fail to meet recommendations in national dietary or physical activity (PA) guidelines. However, there is a lack of understanding of their perspectives on PA and diet to inform intervention design. This study examined young men's motivators and barriers to healthy eating and PA, along with differences by demographic and behavioral factors. A cross-sectional online survey was completed by 282 men aged 18 to 25 years in Australia. Results identified the most common motivators for healthy eating included improving health (63.5%), body image (52.3%), and increasing energy (32.1%). Motivators for PA included improving body image (44.6%), fitness (44.2%), and health (41.0%).

This study examined differences in students' time spent in physical activity (PA) across secondary schools in rural, suburban, and urban environments and identified the environment-level factors associated with these between school differences in students' PA. Multilevel linear regression analyses were used to examine the environment- and student-level characteristics associated with time spent in PA among grades 9 to 12 students attending 76 secondary schools in Ontario, Canada, as part of the SHAPES-Ontario study. This approach was first conducted with the full data set testing for interactions between environment-level factors and school location. Then, school-location specific regression models were run separately. Statistically significant between-school variation was identified among students attending urban (σ(2) μ0  = 8959.63 [372.46]), suburban (σ(2) μ0  = 8918.75 [186.20]), and rural (σ(2) μ0  = 9403.17 [203.69]) schools, where school-level differences accounted for 4.0%, 2.0%, and 2.1% of the variability in students' time spent in PA, respectively. Students attending an urban or suburban school that provided another room for PA or was located within close proximity to a shopping mall or fast food outlet spent more time in PA. Students' time spent in PA varies by school location and some features of the school environment have a different impact on students' time spent in PA by school location. Developing a better understanding of the environment-level characteristics associated with students' time spent in PA by school location may help public health and planning experts to tailor school programs and policies to the needs of students in different locations. © 2013, American School Health Association.

The effects of stress on physical activity and exercise.

Stults-Kolehmainen, Matthew A; Sinha, Rajita

2014-01-01

Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress. The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise. A systematic search of Web of Science, PubMed, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included "stress", "exercise", and "physical activity". A rating scale (0-9) modified for this study was utilized to assess the quality of all studies with multiple time points. The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work-family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely to show an inverse association. 85.7 % of higher-quality prospective research (≥ 7 on a 9-point scale) showed the same trend. Interestingly, some prospective studies (18.2 %) report evidence that PA was positively impacted by stress (behavioral activation). This should not be surprising as some individuals utilize exercise to cope with stress. Several other factors may moderate stress and PA relationships, such as stages of change for exercise. Habitually active individuals exercise more in the face of stress, and those in beginning stages exercise less. Consequently, stress may have a differential impact on exercise adoption, maintenance, and relapse. Preliminary evidence suggests that combining stress management programming with exercise interventions may allay stress-related reductions in PA, though rigorous testing of these techniques has yet to be produced. Overall, the majority of the literature finds that the experience of stress impairs efforts to be physically active. Future work should center on the development of a theory explaining the mechanisms underlying the multifarious influences of stress on PA behaviors.

OBJECTIVE Afterschool programs can be health-promoting environments for children. Written policies positively influence nutrition and physical activity (PA) environments, but effective strategies for building staff capacity to write such policies have not been evaluated. This study measures the comprehensiveness of written nutrition, PA, and screen time policies in afterschool programs and assesses impact of the Out of School Nutrition and Physical Activity (OSNAP) intervention on key policies. METHODS Twenty afterschool programs in Boston, MA participated in a group-randomized, controlled trial from September 2010 to June 2011. Intervention program staff attended learning collaboratives focused on practice and policy change. The Out-of-School Time (OST) Policy Assessment Index evaluated written policies. Inter-rater reliability and construct validity of the measure and impact of the intervention on written policies were assessed. RESULTS The measure demonstrated moderate to excellent inter-rater reliability (Spearman’s r=0.53 to 0.97) and construct validity. OSNAP was associated with significant increases in standards-based policy statements surrounding snacks (+2.6, p=0.003), beverages (+2.3, p=0.008), screen time (+0.8, p=0.046), family communication (+2.2, p=0.002), and a summary index of OSNAP goals (+3.3, p=0.02). CONCLUSIONS OSNAP demonstrated success in building staff capacity to write health-promoting policy statements. Future research should focus on determining policy change impact on practices.

The application of active video games (AVGs) during cardiac rehabilitation (CR) sessions could potentially facilitate patient adherence. The feasibility, safety, and efficacy of in-class AVG supplementation as an alternative to conventional phase 2 programs were investigated. A pilot, evaluator-blinded, intention-to-treat, randomized controlled trial recruited 32 low-moderate risk CR participants and allocated them to conventional or AVG-supplemented exercise. Both groups experienced equal exercise loads for 6 weeks. Patients were assessed at baseline, end of the program, and after an 8-week followup. Adherence and safety-related outcomes were the primary endpoints. Secondary outcomes included change in exercise capacity, daily physical activity (PA), energy expenditure (EE), and psychometric profiling. Patients (males 81%; 60 ± 10 years) presented with typical cardiovascular risk factors and similar baseline characteristics. Participants did not perceive an increased risk of injury and were more interactive. At the end of the program, there was a lower tendency for dropping out (6% vs 19%, P > .05), a significant improvement in PA (322 vs 247 arbitrary acceleration units/min, P = .047) and related EE per body weight (13 vs 11 kcal/kg/d, P = .04) among AVG participants compared with controls. No significant differences between groups for adverse medical events, exercise capacity, affect toward exercise, anxiety, depression, or quality-of-life changes were reported. The additional use of AVGs during CR sessions is feasible, safe, and significantly improved daily PA and EE. A dropout reduction trend among its users, which needs to be confirmed in a larger trial, raises awareness to AVG supplementation as a promising strategy to increase CR adherence.

Public parks are an important resource for the promotion of physical activity (PA). This is the first study in Colombia and the fourth in Latin America to describe the characteristics of park users and their levels of PA using objective measures. A systematic observation assessed sex, age, and the level of PA of users of 10 parks in an intermediate-size city in Colombia, classified in low (5 parks) and high (5 parks) socioeconomic status (SES). A total of 10 daily observations were conducted, in 5 days of the week during 3 periods: morning, afternoon, and evening. In total, 16,671 observations were completed, recording 46,047 users. A higher number of users per park, per day, were recorded in high SES (1195) versus low SES (647). More men were observed in low-SES than high-SES parks (70.1% vs 54.2%), as well as more children were observed in low-SES than high-SES parks (30.1% vs 15.9%). Older adults in high-SES parks were more frequent (9.5% vs 5.2%). Moderate to vigorous PA was higher in low-SES parks (71.7% vs 63.2%). Low-SES parks need more green spaces, walk/bike trails, and areas for PA. All parks need new programs to increase the number of users and their PA level, considering sex, age group, and period of the week.

Key modifiable risk behaviors such as smoking, poor diet and physical inactivity often cluster and may have multiplicative adverse effects on health. This study investigated barriers and facilitators to healthy eating and physical activity (PA) in overweight Mexican-origin smokers to inform the adaptation of an evidence-based smoking cessation program into a multiple health behavior change intervention. Five focus groups were conducted with overweight Mexican-origin men (n = 9) and women (n = 21) who smoked. Barriers and facilitators of healthy eating and PA were identified, and gender differences were assessed. Participants expressed some motivation to eat healthfully and identified strategies for doing so, yet many women experienced difficulties related to personal, family and work-related circumstances. Barriers to healthy eating among men were related to food preferences and lack of familiarity with fruits and vegetables. Participants performed PA primarily within the context of work and domestic responsibilities. Stress/depressed mood, lack of motivation and concern for physical well-being limited further PA engagement. Routines involving eating, PA and smoking highlight how these behaviors may be intertwined. Findings emphasize the importance of social, structural and cultural contexts and call for additional investigation into how to integrate healthy eating and PA into smoking cessation interventions for overweight Mexican-origin smokers. © The Author 2016.

Children spend a significant portion of their days in sedentary behavior (SB) and on average fail to engage in adequate physical activity (PA). The school built environment may influence SB and PA, but research is limited. This natural experiment evaluated whether an elementary school designed to promote movement impacted students' school-time SB and PA. Accelerometers measured SB and PA at pre and post time-points in an intervention group who moved to the new school (n = 21) and in a comparison group experiencing no school environmental change (n = 20). Difference-in-difference (DD) analysis examined SB and PA outcomes in these groups. Measures were also collected post-intervention from an independent, grade-matched group of students in the new school (n = 21). As expected, maturational increases in SB were observed. However, DD analysis estimated that the intervention attenuated increase in SB by 81.2 ± 11.4 minutes/day (p<0.001), controlling for time in moderate to vigorous physical activity (MVPA). The intervention was also estimated to increase daily number of breaks from SB by 23.4 ± 2.6 (p < .001) and to increase light physical activity (LPA) by 67.7 ± 10.7 minutes/day (p<0.001). However, the intervention decreased MVPA by 10.3 ± 2.3 minutes/day (p<0.001). Results of grade-matched independent samples analysis were similar, with students in the new vs. old school spending 90.5 ± 16.1 fewer minutes/day in SB, taking 21.1 ± 2.7 more breaks from SB (p<0.001), and spending 64.5 ± 14.8 more minutes in LPA (p<0.001), controlling for time in MVPA. Students in the new school spent 13.1 ± 2.7 fewer minutes in MVPA (p<0.001) than their counterparts in the old school. This pilot study found that active school design had beneficial effects on SB and LPA, but not on MVPA. Mixed results point to a need for active classroom design strategies to mitigate SB, and quick access from classrooms to areas permissive of high-intensity activities to promote MVPA. Integrating active design with programs/policies to promote PA may yield greatest impact on PA of all intensities.

Identifying state-level policy and provision domains for physical education and physical activity in high school

PubMed Central

2013-01-01

Background It is important to quickly and efficiently identify policies that are effective at changing behavior; therefore, we must be able to quantify and evaluate the effect of those policies and of changes to those policies. The purpose of this study was to develop state-level physical education (PE) and physical activity (PA) policy domain scores at the high-school level. Policy domain scores were developed with a focus on measuring policy change. Methods Exploratory factor analysis was used to group items from the state-level School Health Policies and Programs Study (SHPPS) into policy domains. Items that related to PA or PE at the High School level were identified from the 7 SHPPS health program surveys. Data from 2000 and 2006 were used in the factor analysis. RESULTS: From the 98 items identified, 17 policy domains were extracted. Average policy domain change scores were positive for 12 policy domains, with the largest increases for “Discouraging PA as Punishment”, “Collaboration”, and “Staff Development Opportunities”. On average, states increased scores in 4.94 ± 2.76 policy domains, decreased in 3.53 ± 2.03, and had no change in 7.69 ± 2.09 policy domains. Significant correlations were found between several policy domain scores. Conclusions Quantifying policy change and its impact is integral to the policy making and revision process. Our results build on previous research offering a way to examine changes in state-level policies related to PE and PA of high-school students and the faculty and staff who serve them. This work provides methods for combining state-level policies relevant to PE or PA in youth for studies of their impact. PMID:23815860

Performance Assessment Program for the Savannah River Site Liquid Waste Facilities - 13610

Rosenberger, Kent H.

2013-07-01

The Liquid Waste facilities at the U.S. Department of Energy's (DOE) Savannah River Site (SRS) are operated by Liquid Waste Operations contractor Savannah River Remediation LLC (SRR). A separate Performance Assessment (PA) is prepared to support disposal operations at the Saltstone Disposal Facility and closure evaluations for the two liquid waste tank farm facilities at SRS, F-Tank Farm and H-Tank Farm. A PA provides the technical basis and results to be used in subsequent documents to demonstrate compliance with the pertinent requirements identified in operations and closure regulatory guidance. The Saltstone Disposal Facility is subject to a State of Southmore » Carolina industrial solid waste landfill permit and the tank farms are subject to a state industrial waste water permit. The three Liquid Waste facilities are also subject to a Federal Facility Agreement approved by the State, DOE and the Environmental Protection Agency (EPA). Due to the regulatory structure, a PA is a key technical document reviewed by the DOE, the State of South Carolina and the EPA. As the waste material disposed of in the Saltstone Disposal Facility and the residual material in the closed tank farms is also subject to reclassification prior to closure via a waste determination pursuant to Section 3116 of the Ronald W. Reagan National Defense Authorization Act of Fiscal Year 2005, the U.S. Nuclear Regulatory Commission (NRC) is also a reviewing agency for the PAs. Pursuant to the Act, the NRC also has a continuing role to monitor disposal actions to assess compliance with stated performance objectives. The Liquid Waste PA program at SRS represents a continual process over the life of the disposal and closure operations. When the need for a PA or PA revision is identified, the first step is to develop a conceptual model to best represent the facility conditions. The conceptual model will include physical dimensions of the closed system, both the engineered and natural system, and modeling input parameters associated with the modeled features, both initial values (at the time of facility closure) and degradation rates/values. During the development of the PA, evaluations are conducted to reflect not only the results associated with the best available information at the time but also to evaluate potential uncertainties and sensitivities associated with the modeled system. While the PA will reflect the modeled system results from the best available information, it will also identify areas for future work to reduce overall PA uncertainties moving forward. DOE requires a PA Maintenance Program such that work continues to reduce model uncertainties, thus bolstering confidence in PA results that support regulatory decisions. This maintenance work may include new Research and Development activities or modeling as informed by previous PA results and other new information that becomes available. As new information becomes available, it is evaluated against previous PAs and appropriate actions are taken to ensure continued confidence in the regulatory decisions. Therefore, the PA program is a continual process that is not just the development of a PA but seeks to incorporate new information to reduce overall model uncertainty and provide continuing confidence in regulatory decisions.

Testing the Efficacy of OurSpace, a Brief, Group Dynamics-Based Physical Activity Intervention: A Randomized Controlled Trial.

PubMed

Irwin, Brandon; Kurz, Daniel; Chalin, Patrice; Thompson, Nicholas

2016-05-06

Emerging technologies (ie, mobile phones, Internet) may be effective tools for promoting physical activity (PA). However, few interventions have provided effective means to enhance social support through these platforms. Face-to-face programs that use group dynamics-based principles of behavior change have been shown to be highly effective in enhancing social support through promoting group cohesion and PA, but to date, no studies have examined their effects in Web-based programs. The aim was to explore proof of concept and test the efficacy of a brief, online group dynamics-based intervention on PA in a controlled experiment. We expected that the impact of the intervention on PA would be moderated by perceptions of cohesion and the partner's degree of presence in the online media. Participants (n=135) were randomized into same-sex dyads and randomly assigned to one of four experimental conditions: standard social support (standard), group dynamics-based-high presence, group dynamics-based-low presence, or individual control. Participants performed two sets of planking exercises (pre-post). Between sets, participants in partnered conditions interacted with a virtual partner using either a standard social support app or a group dynamics-based app (group dynamics-based-low presence and group dynamics-based-high presence), the latter of which they participated in a series of online team-building exercises. Individual participants were given an equivalent rest period between sets. To increase presence during the second set, participants in the group dynamics-based-high presence group saw a live video stream of their partner exercising. Perceptions of cohesion were measured using a modified PA Group Environment Questionnaire. Physical activity was calculated as the time persisted during set 2 after controlling for persistence in set 1. Perceptions of cohesion were higher in the group dynamics-based-low presence (overall mean 5.81, SD 1.04) condition compared to the standard (overall mean 5.04, SD 0.81) conditions ( P=.006), but did not differ between group dynamics-based-low presence and group dynamics-based-high presence (overall mean 5.42, SD 1.07) conditions ( P=.25). Physical activity was higher in the high presence condition (mean 64.48, SD 20.19, P=.01) than all other conditions (mean 53.3, SD 17.35). A brief, online group dynamics-based intervention may be an effective method of improving group cohesion in virtual PA groups. However, it may be insufficient on its own to improve PA.

Background Multicomponent school-based interventions have the potential to reduce the age-related decline in adolescents' physical activity (PA), yet there is not consistent evidence to guide non-curricular and school environment interventions. The aim of this study was to assess the effectiveness of a multicomponent environmental school-based intervention, designed to reduce the age-related decline in PA among adolescents. Methods A cluster randomized controlled trial was conducted with 7 intervention and 7 control schools. Baseline measurements were carried out in spring 2010 with 2 years of follow-up. A total of 1,348 students (11–13 years, in grade 5 and 6) enrolled in the study at baseline. The 14 schools included in the study were located in the Region of Southern Denmark. The intervention consisted of organizational and physical changes in the school environment with a total of 11 intervention components. The primary outcome measure was overall PA (cpm, counts per minute) and was supported by analyses of time spent in MVPA, and time spent sedentary. Furthermore, a secondary outcome measure was PA in school time and during recess. PA was measured using accelerometer (Actigraph GT3X). Results A total of 797 students completed the trial and had valid accelerometer data. No significant difference was found for overall PA with an adjusted difference of −19.1 cpm (95% CI: −93, 53) or for school time activity with an adjusted difference of 6 cpm (95% CI: −73, 85). A sensitivity analysis revealed a positive significant intervention effect of PA in recess with an adjusted difference of 95 cpm. Conclusions No evidence was found of the overall effect of a non-curricular multicomponent school-based intervention on PA among Danish adolescents. The intervention was positively associated with PA during school time and recess, however, with small estimates. Lack of effect on overall PA could be due to both program theory and different degrees of implementation. Trial Registration www.Controlled-Trials.com ISRCTN79122411 PMID:24921948

The purpose of this study was to employ high-frequency accelerometry to explore parent-child physical activity (PA) relationships across a free-living sample. We recorded 7 days of wrist-mounted accelerometry data from 168 dyads of elementary-aged children and their parents. Using a custom MATLAB program (Natick, MA), we summed child and parent accelerations over 1 and 60 seconds, respectively, and applied published cut points to determine the amount of time spent in moderate-vigorous PA (MVPA). Bivariate and partial correlations examined parent-child relationships between percentage of time spent in MVPA. Weak to moderate positive correlations were observed before school (r = .326, P < .001), after school (r = .176, P = .023), during the evening (r = .213, P = .006), and on weekends (r = .231, P = .003). Partial correlations controlling for parent-child MVPA revealed significant relationships during the school day (r = .185, P = .017), before school (r = .315, P < .001), and on weekends (r = .266, P = .001). In addition, parents of more active children were significantly more active than parents of less active children during the evening. These data suggest that there is some association between parent-child PA, especially before school and on weekends. Future interventions aiming to increase PA among adults and children must consider patterns of MVPA specific to children and parents and target them accordingly.

Nurse-Led School-Based Child Obesity Prevention.

School-based childhood obesity prevention programs have grown in response to reductions in child physical activity (PA), increased sedentariness, poor diet, and soaring child obesity rates. Multiple systematic reviews indicate school-based obesity prevention/treatment interventions are effective, yet few studies have examined the school nurse role in obesity interventions. Building on a previous study, this study examines a refined health messaging (Let's Go 5-2-1-0) program delivered to fourth and fifth graders (n = 72) by a school nurse with reinforcement on-site health coaching by senior nursing students. Two nursing schools and two elementary schools participated. Measures of PA, body mass index percentile, and self-reported health habits were collected at baseline (School A, September 2009 and School B, January 2010) and end of year (April 2010 for both schools). Findings included statistically significant increases in PA levels and improvements in child-reported health habits. School nurses can influence obesity prevention. Further research on adoption of school nurse-led obesity interventions is warranted. © The Author(s) 2015.

Fewer than 50% of middle-aged women participate in regular physical activity (PA). Innovative approaches that engage women who may not otherwise participate in PA programs are warranted. The purpose of this study was to explore the acceptability and feasibility of a 12-week tablet-based book club for improving middle-aged women's PA. Thirty women (35-64 years of age) were randomized to the Fit Minded Tablet (n=15) and the Standard Fit Minded (i.e., face-to-face intervention) (n=15) groups. The Fit Minded Tablet was adapted from the Standard Fit Minded, a previously tested, theory-based book club intervention using books as a platform for discussion and group support to help women adopt regular PA. Both interventions met weekly for 3 months, for a total of 12 sessions. Tablet group participants accessed materials (e.g., e-books, workbook, live/recorded videoconferencing) via a tablet computer; Standard group participants received materials (e.g., printed books, workbook, live face-to-face meetings) in person. Feasibility (i.e., implementation and expansion) was assessed using process evaluation, qualitative interviews, satisfaction surveys, and quantitative outcome assessments. Women in the Tablet group attended fewer meetings (mean, 8.25) than women in the Standard group (mean, 9.9). Videoconferencing, digital literacy, and participant engagement limitations were observed in the Tablet group. Tablet participants enjoyed the e-books but thought technology barriers hindered their engagement during meetings. Women in both groups valued the support they received from other group members. Standard participants cited this support as a key contributor to their PA changes, whereas Tablet participants reported needing in-person contact to feel more connected. Given the popularity of tablet computers and the value that middle-aged women place on group interaction to support their PA behaviors, additional research is warranted to determine best strategies for optimizing social support, mitigating technology barriers, and improving engagement in online and mobile health promotion programs targeting middle-aged women.

Health-related behaviors [physical activity (PA), nutritional quality of breakfast and sleep]; personal variables (self-esteem, attitudes to PA and gender) and socioeconomic status (SES) (school SES and parental education), were examined in relation to literacy and numeracy scores of 824 grade 3-7 children. Participants completed a questionnaire, and their national literacy and numeracy test scores were retrieved. Mothers (N = 755) completed a telephone interview. Students of highest school SES, maternal education, nutritional quality of breakfast, more sedentary time and female gender had higher literacy scores. SES, maternal education, male gender and total minutes of daily PA were predictors of numeracy with an interaction between greater total PA in boys and greater numeracy. Even though the socioeconomic factors that have predicted children's academic achievement for many decades are still clearly set in place, there are also other modifiable health influences that affect literacy and numeracy and are independent of SES. The current findings provide evidence for health educators and school administrators who may garner support for both breakfast programs and daily school PA for the dual purposes of health promotion as well as for the improvement of literacy and numeracy in settings in which social class may be acting against the educational interests of disadvantaged children.

Disparities in health perspectives between Indigenous and non-Indigenous populations are major concerns in many of the world's well-developed nations. Indigenous populations are largely less healthy, more prone to chronic diseases, and have an earlier overall mortality than non-Indigenous populations. Low levels of physical activity (PA) contribute to the high levels of disease in Indigenous Australians. Qualitative analysis of structured one-on-one interviews discussing PA in a regional setting. Participants were 12 Indigenous Australian adults, and 12 non-Indigenous Australian adults matched on age, sex, and basketball division. Most participants reported engaging in regular exercise; however, the Indigenous group reported more barriers to PA. These factors included cost, time management and environmental constraints. The physical facilitators identified by our Indigenous sample included social support, intrinsic motivation and role modelling. Findings describe individual and external factors that promote or constraint PA as reported by Indigenous Australian adults. Results indicate that Indigenous people face specific barriers to PA when compared to a non-Indigenous sample. Implications for public health: This study is the first to compare the perspective of Indigenous Australians to a matched group of non-Indigenous Australians and provides useful knowledge to develop public health programs based on culturally sensitive data. © 2017 The Authors.

Youth risk of obesity is high during the summer months. Summer day camps can be ideal settings for preventing obesity through reducing youth summer sedentary behaviors. However, with limited research on camp settings, the mechanisms by which these programs promote children's physical activity (PA) remains largely unknown. The current study was designed to take a first step in addressing this gap in research through systematic observations of 4 summer day camps. Systematic observations of 4 summer day camps was conducted using the System for Observing Play and Leisure Activity in Youth (SOPLAY) and a social-motivational climate supplemental observation tool founded on Self-Determination Theory and previous research developed by the authors. Teams of two coders observed daily activities for four days across two-week periods at each camp. On 15 minute intervals throughout each day, camps were assessed on level of youth PA (e.g., sedentary, moderate, vigorous), five physical features (e.g., equipment), eight staff interactions (e.g., encourage PA), and six social climate components (e.g., inclusive game). Across the sample, highly engaging games [F(1,329) = 17.68, p < .001], positive peer interactions [F(1,329) = 8.43, p < .01], and bullying [F(1,329) = 9.39, p < .01] were significantly related to higher PA participation rates, and clarity of rules [F(1,329) = 11.12, p < .001] was related to fewer youth participating in PA. Separate analyses for males and females indicated some sex differences with highly engaging games [F(1,329) = 23.10, p < .001] and bullying [F(1,329) = 10.00, p < .01] related to males' but not females' PA, and positive peer interactions related to only females' PA [F(1,329) = 9.58, p < .01]. Small, yet significant physical-environmental effects of temperature [F(1,328) = 1.54, p < .05] and equipment [F(1,328) = 4.34, p = .05] for girls also suggests that activities offered indoors (which was most common during high temperatures), and provision of equipment may also be important considerations for promoting girls' PA. Staff behaviors were minimally predictive of youth PA. This is the first study to conduct systematic observations of the physical and social resources of summer day camps and contributes to our understanding of the strengths and needs of camps to effectively promote PA in both boys and girls during the summer months when risks for obesity are high.

Toddlerhood is an important age for physical activity (PA) promotion to prevent obesity and support a physically active lifestyle throughout childhood. Accurate assessment of PA is needed to determine trends/correlates of PA, time spent in sedentary, light, or moderate-vigorous PA (MVPA), and the effectiveness of PA promotion programs. Due to the limited availability of objective measures that have been validated and evaluated for feasibility in community studies, it is unclear which subgroups of toddlers are at the highest risk for inactivity. Using Actical ankle accelerometry, the objectives of this study are to develop valid thresholds, examine feasibility, and examine demographic/ anthropometric PA correlates of MVPA among toddlers from low-income families. Two studies were conducted with toddlers (12-36 months). Laboratory Study (n = 24)- Two Actical accelerometers were placed on the ankle. PA was observed using the Child Activity Rating Scale (CARS, prescribed activities). Analyses included device equivalence reliability (correlation: activity counts of two Acticals), criterion-related validity (correlation: activity counts and CARS ratings), and sensitivity/specificity for thresholds. Community Study (n = 277, low-income mother-toddler dyads recruited)- An Actical was worn on the ankle for > 7 days (goal >5, 24-h days). Height/weight was measured. Mothers reported demographics. Analyses included frequencies (feasibility) and stepwise multiple linear regression (sMLR). Laboratory Study- Acticals demonstrated reliability (r = 0.980) and validity (r = 0.75). Thresholds demonstrated sensitivity (86 %) and specificity (88 %). Community Study- 86 % wore accelerometer, 69 % had valid data (mean = 5.2 days). Primary reasons for missing/invalid data: refusal (14 %) and wear-time ≤2 days (11 %). The MVPA threshold (>2200 cpm) yielded 54 min/day. In sMLR, MVPA was associated with age (older > younger, β = 32.8, p < 0.001), gender (boys > girls, β = -11.21, p = 0.032), maternal MVPA (β = 0.44, p = 0.002) and recruitment location (suburban > urban, β = 19.6, p < 0.001), or race (non-Black > Black, β = 18.5, p = 0.001). No association with toddler weight status. Ankle accelerometry is a valid, reliable, and feasible method of assessing PA in community studies of toddlers from low-income families. Sub-populations of toddlers may be at increased risk for inactivity, including toddlers that are younger, female, Black, those with less active mothers, and those living in an urban location.

The Effects of Stress on Physical Activity and Exercise

Background Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress. Objective The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise. Methods A systematic search of Web of Science, Pub-Med, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included “stress”, “exercise”, and “physical activity”. A rating scale (0–9) modified for this study was utilized to assess the quality of all studies with multiple time points. Results The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work–family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely to show an inverse association. 85.7 % of higher-quality prospective research (≥7 on a 9-point scale) showed the same trend. Interestingly, some prospective studies (18.2 %) report evidence that PA was positively impacted by stress (behavioral activation). This should not be surprising as some individuals utilize exercise to cope with stress. Several other factors may moderate stress and PA relationships, such as stages of change for exercise. Habitually active individuals exercise more in the face of stress, and those in beginning stages exercise less. Consequently, stress may have a differential impact on exercise adoption, maintenance, and relapse. Preliminary evidence suggests that combining stress management programming with exercise interventions may allay stress-related reductions in PA, though rigorous testing of these techniques has yet to be produced. Conclusions Overall, the majority of the literature finds that the experience of stress impairs efforts to be physically active. Future work should center on the development of a theory explaining the mechanisms underlying the multifarious influences of stress on PA behaviors. PMID:24030837

The determinants of physical activity (PA) and body fatness in Chinese adolescents are rarely examined. This study aimed to investigate the effect of attitude toward PA, screen time, parents' socioeconomic status (SES), and exercise habit on PA and body fatness among Chinese children by using structural equation modeling (SEM) analysis. Data obtained from the second Community Fitness Survey in Hong Kong were utilized, in which students from one secondary school of each of the 18 districts of Hong Kong were recruited. A total of 2517 questionnaires with physical fitness items were successfully distributed to students aged 13-19 years in these districts. Families' SES, parents' exercise habit, children's intention to participate in PA, amount of moderate to vigorous PA (MVPA), screen time, children's attitude toward PA, and children's body fat percentage were measured and analyzed with SEM. The structural equation model was composed of a measurement model and a structural model. The model was tested with Mplus 6. The Chi-square test, root mean square error of approximation, comparative fit index, and Tucker-Lewis index were calculated to evaluate model fit. The model was then modified based on the model fit indices. Children's intention to participate in PA was a strong predictor of their engagement in MVPA. Parents' exercise habit had both direct and indirect (via attitude) effects on their children's intention to participate in PA. Screen time was not a predictor of body composition. Children's intention to participate in PA directly affected their body composition. Children's attitude toward PA, parents' exercise habit, and SES had significant effects on the children's intention to participate in PA. Furthermore, obesity had a negative effect on the children's attitude toward PA. To promote MVPA and prevent obesity in Chinese children of Hong Kong, it is important to design intervention that enhances children's intention and attitude in PA, as well as parent's exercise habits. Tailormade programs that take SES into consideration are also essential. Further studies are necessary to extend the results and test the model in other metropolitan areas in China.

Objectives Refugees resettled in the US may be at risk for cardiovascular disease (CVD). However, little is known about CVD-related issues among Karen refugees who have migrated to the US from the Thai-Myanmar border. The purpose of this study was to examine CVD-related health beliefs and lifestyle issues among Karen refugees resettled in the US. Methods Karen refugees resettled in the US from the Thai-Myanmar border (n=195) participated in a survey study on health beliefs related to CVD, salt intake, physical activity (PA), and smoking in the fall of 2016. Results A high-salt diet, physical inactivity, and smoking were major lifestyle problems. Participants who adhered to a low-salt diet considered themselves to be susceptible to CVD. Most participants did not engage in regular PA. Regular PA was associated with less perceived susceptibility to CVD and greater perceived benefits of a healthy lifestyle for decreasing the likelihood of CVD. Conclusions Each refugee population may require individualized strategies to promote PA and a healthy diet. Future studies should develop health education programs that are specifically designed for Karen refugees and evaluate such programs. In addition to health education programs on healthy lifestyle choices, tobacco cessation programs seem to be necessary for Karen refugees. At the same time, it is important to foster strategies to increase the utilization of preventive care among this population by promoting free or reduced-fee resources in the community to further promote their health.

Physical functioning (PF) and physical activity (PA) are low in patients treated with maintenance hemodialysis (MHD). Little information exists on this topic in patients treated with peritoneal dialysis (PD). The objective of this study was to compare PF and PA in patients with Stage-5 chronic kidney disease (CKD) treated with PD and in-center MHD. Physical functioning was measured in 45 prevalent PD patients using standard physical performance measures that include gait speed, chair stand, standing balance, 6-minute-walk, incremental shuttle walk and self-reported PF using the short form (SF)-36 questionnaire. Physical activity was determined from self-report and using the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire. Scores for the short physical performance battery (SPPB) were calculated. In-center MHD patients were matched by age, gender, and diabetes status to the PD patients. Unadjusted comparisons showed significantly higher 6-minute-walk distance, shuttle-walk distance and hand-grip in the PD patients. Adjustment in multiple regression analysis resulted in only gait speed being significantly different between the groups. All test results in both groups were lower than reference values for age and gender in the general population, and were at the levels indicating impairment. Physical activity was not different between the 2 groups (average age 49 yrs), and both groups had weekly caloric expenditure from all exercise and from moderate-intensity exercise that was similar to older (> 70 yrs) community-dwelling adults. Adjusted association indicated that PA was significantly associated with shuttle-walk distance. Physical functioning and PA measures were low in both PD and MHD groups. Interventions to improve PA and PF should be strongly considered for both PD and MHD patients. Copyright © 2017 International Society for Peritoneal Dialysis.

Men have been a hard-to-reach population in health behavior programs and it has been claimed that they are less interested in health issues than women. However, less is known about that how ready men are to adopt new health behaviors. This study examined readiness for change in physical activity (PA) and eating behavior (EB) among low fitness and overweight working-aged Finnish men who participated in a PA campaign. Associations among perceived health knowledge, health behaviors, psychosocial factors and readiness for change were studied. Data comprised 362 men aged 18-64. Physical fitness was assessed with a body fitness index constructed on the basis of the Polar OwnIndex Test, a hand grip test and an Inbody 720 body composition analysis. Health behavior information was gathered by questionnaire. Descriptive and comparative analyses were conducted by χ 2 test and Kruskall-Wallis and Mann-Whitney U tests. Associations between health knowledge and health behaviors were explored with logistic regression analyses. Readiness to increase PA and change EB was positively related to higher scores in psychosocial factors, PA and healthy eating habits. Self-rated knowledge on health issues was not related to PA or readiness to change health behaviors; however, it was positively associated with healthy eating and greater perceived promoters of PA. Participants' self-rated knowledge reflected not only an interest in health but also the differences in age and education. Health programs are needed that target both PA and healthy eating in low-fit men at different ages and motivational stages. © The Author 2015. Published by Oxford University Press.

Intrapleural processing of prourokinase (scuPA) in tetracycline (TCN)-induced pleural injury in rabbits was evaluated to better understand the mechanisms governing successful scuPA-based intrapleural fibrinolytic therapy (IPFT), capable of clearing pleural adhesions in this model. Pleural fluid (PF) was withdrawn 0–80 min and 24 h after IPFT with scuPA (0–0.5 mg/kg), and activities of free urokinase (uPA), plasminogen activator inhibitor-1 (PAI-1), and uPA complexed with α-macroglobulin (αM) were assessed. Similar analyses were performed using PFs from patients with empyema, parapneumonic, and malignant pleural effusions. The peak of uPA activity (5–40 min) reciprocally correlated with the dose of intrapleural scuPA. Endogenous active PAI-1 (10–20 nM) decreased the rate of intrapleural scuPA activation. The slow step of intrapleural inactivation of free uPA (t1/2β = 40 ± 10 min) was dose independent and 6.7-fold slower than in blood. Up to 260 ± 70 nM of αM/uPA formed in vivo [second order association rate (kass) = 580 ± 60 M−1·s−1]. αM/uPA and products of its degradation contributed to durable intrapleural plasminogen activation up to 24 h after IPFT. Active PAI-1, active α2M, and α2M/uPA found in empyema, pneumonia, and malignant PFs demonstrate the capacity to support similar mechanisms in humans. Intrapleural scuPA processing differs from that in the bloodstream and includes 1) dose-dependent control of scuPA activation by endogenous active PAI-1; 2) two-step inactivation of free uPA with simultaneous formation of αM/uPA; and 3) slow intrapleural degradation of αM/uPA releasing active free uPA. This mechanism offers potential clinically relevant advantages that may enhance the bioavailability of intrapleural scuPA and may mitigate the risk of bleeding complications. PMID:23997178

We present results of the 2016 Healthy Active Kids South Africa (HAKSA) Report Card on the current status of physical activity (PA) and nutrition in South African youth. The context in which we interpret the findings is that participation in PA is a fundamental human right, along with the right to "attainment of the highest standard of health." The HAKSA 2016 Writing Group was comprised of 33 authorities in physical education, exercise science, nutrition, public health, and journalism. The search strategy was based on peer-reviewed manuscripts, dissertations, and 'gray' literature. The core PA indicators are Overall Physical Activity Level; Organized Sport Participation; Active and Outdoor Play; Active Transportation; Sedentary Behaviors; Family and Peer Influences; School; Community and the Built Environment; and National Government Policy, Strategies, and Investment. In addition, we reported on Physical Fitness and Motor Proficiency separately. We also reported on nutrition indicators including Overweight and Under-nutrition along with certain key behaviors such as Fruit and Vegetable Intake, and policies and programs including School Nutrition Programs and Tuck Shops. Data were extracted and grades assigned after consensus was reached. Grades were assigned to each indicator ranging from an A, succeeding with a large majority of children and youth (81% to 100%); B, succeeding with well over half of children and youth (61% to 80%); C, succeeding with about half of children and youth (41% to 60%); D, succeeding with less than half but some children and youth (21% to 40%); and F, succeeding with very few children and youth (0% to 20%); INC is inconclusive. Overall PA levels received a C grade, as we are succeeding with more than 50% of children meeting recommendations. Organized Sports Participation also received a C, and Government Policies remain promising, receiving a B. Screen time and sedentary behavior were a major concern. Under- and over-weight were highlighted and, as overweight is on the rise, received a D grade. In particular, issues of food security, obesogenic environments, and access to activity-supportive environments should guide social mobilization downstream and policy upstream. There is an urgent need for practice-based evidence based on evaluation of existing, scaled up interventions.

To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents' leisure-time physical activity (PA). Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006-07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA. Perceived availability of sport facilities was positively (OR(boys) = 1.17; OR(girls) = 1.26), and that of computer/Internet negatively (OR(boys) = 0.48; OR(girls) = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (OR(girls) = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (OR(boys) = 1.26; OR(girls) = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (OR(boys) = 0.60; OR(girls) = 0.54). Perceived availability of sport facilities in the neighborhood may positively impact on adolescents' level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component.

Women account for more than 70% of physician assistant (PA) students, 62% of practicing PAs, and 57% of faculty in PA programs. About half of all US medical students, 30% of actively practicing physicians, and 37% of faculty at academic medical centers are female. However, women in medicine are paid less than men for equal work effort and achieve fewer leadership positions within academia and medicine. Neglecting the skills and talents of women may lead to a workforce that fails to represent our patient and student populations.

Healthy ageing is an important concern for many societies facing the challenge of an ageing population. Physical activity (PA) is a major contributor to healthy ageing; however insufficient PA levels are prevalent in old age in Germany. Community capacity building and community involvement are often recommended as key strategies to improve equitable access to prevention and health promotion. However, evidence for the effectiveness of these strategies is scarce. This study aims to assess the community readiness for PA promotion in local environments and to analyse the utility of strategies to increase community readiness for reaching vulnerable groups. We designed a mixed method intervention trial comprising three study modules. The first module includes an assessment of community readiness for PA interventions in older adults. The assessment is carried out in a sample of 24 municipalities in the Northwest of Germany using structured key informant interviews. In the second module, eight municipalities with the low community readiness are selected from the sample and randomly assigned to one of two study groups: active enhancement of community readiness (intervention) versus no enhancement (control). After enhancing community readiness in the active enhancement group, older adults in both study groups will be recruited for participation in a PA intervention. Participation rates are compared between the study groups to evaluate the effects of the intervention. In addition, a cost-effectiveness analysis is carried out calculating recruitment costs per person reached in the two study groups. In the third module, qualitative interviews are conducted with participants and non-participants of the PA intervention exploring reasons for participation or non-participation. This study offers the potential to contribute to the evidence base of reaching vulnerable older adults for PA interventions and provide ideas on how to reduce participation barriers. Its findings will inform governmental authorities, professionals, academics, and NGOs with an estimate of resources necessary to achieve equitable access to physical activity programs for vulnerable older adults.

Background: Childhood obesity has been becoming a worldwide public health problem. We conducted a community-based physical activity (PA) intervention program aiming at childhood obesity prevention in general student population in Nanjing of China, the host city of the 2nd World Summer Youth Olympic Games (YOG-Obesity study). Methods: This was a cluster randomized controlled intervention study. Participants were the 4th (mean age±s.e.: 9.0±0.01) and 7th (mean age±s.e.: 12.0±0.01) grade students (mean age±s.e.: 10.5±0.02) from 48 schools and randomly allocated (1:1) to intervention or control groups at school level. Routine health education was provided to all schools, whereas the intervention schools additionally received an 1-year tailored multi-component PA intervention program, including classroom curricula, school environment support, family involvement and fun programs/events. The primary outcome measures were changes in body mass index, obesity occurrence and PA. Results: Overall, 9858 (97.7%) of the 10091 enrolled students completed the follow-up survey. Compared with the baseline, PA level increased by 33.13 min per week (s.e. 10.86) in the intervention group but decreased by 1.76 min per week (s.e. 11.53) in the control group (P=0.028). After adjustment for potential confounders, compared with the control group, the intervention group were more likely to have increased time of PA (adj. Odds ratio=1.15, 95% confidence interval=1.06–1.25), but had a smaller increase in mean body mass index (BMI) (0.22 (s.e. 0.02) vs 0.46 (0.02), P=0.01) and BMI z-score (0.07 (0.01) vs 0.16 (0.01), P=0.01), and were less likely to be obese (adj. Odds ratio=0.7, 95% confidence interval=0.6, 0.9) at study end. The intervention group had fewer new events of obesity/overweight but a larger proportion of formerly overweight/obese students having normal weight by study end. Conclusions: This large community-based PA intervention was feasible and effective in promoting PA and preventing obesity among the general student population in a large city in China. Experiences from this study are the lessons for China to control the childhood obesity epidemic. PMID:28978975

Childhood obesity has been becoming a worldwide public health problem. We conducted a community-based physical activity (PA) intervention program aiming at childhood obesity prevention in general student population in Nanjing of China, the host city of the 2nd World Summer Youth Olympic Games (YOG-Obesity study). This was a cluster randomized controlled intervention study. Participants were the 4th (mean age±s.e.: 9.0±0.01) and 7th (mean age±s.e.: 12.0±0.01) grade students (mean age±s.e.: 10.5±0.02) from 48 schools and randomly allocated (1:1) to intervention or control groups at school level. Routine health education was provided to all schools, whereas the intervention schools additionally received an 1-year tailored multi-component PA intervention program, including classroom curricula, school environment support, family involvement and fun programs/events. The primary outcome measures were changes in body mass index, obesity occurrence and PA. Overall, 9858 (97.7%) of the 10091 enrolled students completed the follow-up survey. Compared with the baseline, PA level increased by 33.13 min per week (s.e. 10.86) in the intervention group but decreased by 1.76 min per week (s.e. 11.53) in the control group (P=0.028). After adjustment for potential confounders, compared with the control group, the intervention group were more likely to have increased time of PA (adj. Odds ratio=1.15, 95% confidence interval=1.06-1.25), but had a smaller increase in mean body mass index (BMI) (0.22 (s.e. 0.02) vs 0.46 (0.02), P=0.01) and BMI z-score (0.07 (0.01) vs 0.16 (0.01), P=0.01), and were less likely to be obese (adj. Odds ratio=0.7, 95% confidence interval=0.6, 0.9) at study end. The intervention group had fewer new events of obesity/overweight but a larger proportion of formerly overweight/obese students having normal weight by study end. This large community-based PA intervention was feasible and effective in promoting PA and preventing obesity among the general student population in a large city in China. Experiences from this study are the lessons for China to control the childhood obesity epidemic.

Activated pancreatic stellate cells (PaSCs) are the key cellular source of cancer-associated fibroblasts in the pancreatic stroma of patients with pancreatic ductal adenocarcinoma (PDAC), however, the activation mechanism of PaSCs is not yet known. The Notch signaling pathway, components of which are expressed in stromal cells, is involved in the fibrosis of several organs, including the lung and liver. In the current study, we investigated whether Notch signal transduction is involved in PaSC activation in PDAC. The expression of Notch signaling pathway components in human PDAC was examined via immunohistochemical staining and assessed in mouse PaSCs using RT-qPCR and western blotting. Notch3 expression in both PDAC stromal cells and activated mouse PaSCs was evaluated using immunofluorescence, RT-qPCR and western blotting. The impact of siRNA-mediated Notch3 knockdown on PaSC activation was detected with RT-qPCR and western blotting, and the impact on PaSC proliferation and migration was detected using CCK-8 assays and scratch experiments. The effect of conditioned medium from PaSCs activated with Notch3 siRNA on pancreatic cancer (LTPA) cells was also detected with CCK-8 assays and scratch experiments. The data were analyzed for statistical significance using Student's t-test. Notch3 was overexpressed in both human PDAC stromal cells and activated mouse PaSCs, and Notch3 knockdown with Notch3 siRNA decreased the proliferation and migration of mouse PaSCs. The levels of markers related to PaSC activation, such as α-smooth muscle actin (α-SMA), collagen I and fibronectin, decreased in response to Notch3 knockdown, indicating that Notch3 plays an important role in PaSC activation. Furthermore, we confirmed that inhibition of PaSC activation via Notch3 siRNA reduced the proliferation and migration of PaSC-induced mouse pancreatic cancer (LTPA) cells. Notch3 inhibition in PaSCs can inhibit the activation, proliferation and migration of PaSCs and reduce the PaSC-induced pro-tumorigenic effect. Therefore, Notch3 silencing in PaSCs is a potential novel therapeutic option for patients with PDAC.

To describe educational practices of physician assistant (PA) programs regarding spirituality and religion discussions during patient encounters. Patients want their health care provider to be aware of their spiritual and religious beliefs. This topic is addressed in physician and nursing education but may not be included in PA programs. Data regarding curriculum were collected via electronic survey emailed to 143 PA programs across the United States. Thirty-eight programs responded for a response rate of 27%. Most (68.4%) program respondents reported students' desire to be trained to discuss spirituality and religion, yet 36.8% do not offer this training. Just over half (69.2%) would consider adding curriculum to teach students to discuss spirituality, but the majority (92.3%) would not add curriculum to discuss religion during patient encounters. PA programs offer training to discuss spirituality in patient encounters but not to discuss religiosity. Programs may want to consider adding some curriculum to increase PAs awareness of spirituality and religion needs of patients.

The 'active school' model offers promise for promoting school-based physical activity (PA); however, few intervention trials have evaluated its effectiveness. Thus, our purpose was to: (1) describe Action Schools! BC (AS! BC) and its implementation (fidelity and feasibility) and (2) evaluate the impact of AS! BC on school provision of PA. Ten elementary schools were randomly assigned to one of the three conditions: Usual Practice (UP, three schools), Liaison (LS, four schools) or Champion (CS, three schools). Teachers in LS and CS schools received AS! BC training and resources but differed on the level of facilitation provided. UP schools continued with regular PA. Delivery of PA during the 11-month intervention was assessed with weekly Activity Logs and intervention fidelity and feasibility were assessed using Action Plans, workshop evaluations, teacher surveys and focus groups with administrators, teachers, parents and students. Physical activity delivered was significantly greater in LS (+67.4 min/week; 95% CI: 18.7-116.1) and CS (+55.2 min/week; 95% CI: 26.4-83.9) schools than UP schools. Analysis of Action Plans and Activity Logs showed fidelity to the model and moderate levels of compliance (75%). Teachers were highly satisfied with training and support. Benefits of AS! BC included positive changes in the children and school climate, including provision of resources, improved communication and program flexibility. These results support the use of the 'active school' model to positively alter the school environment. The AS! BC model was effective, providing more opportunities for "more children to be more active more often" and as such has the potential to provide health benefits to elementary school children.

Physical inactivity is one of the major public health problems worldwide. Community-based interventions have been pointed out as a promising strategy to increase physical activity (PA) levels and impact population health. Recreovía is a community program with a potential to promote PA. There is growing evidence for two benefits derived from the practice of PA: an increased perception of health-related quality of life (HRQoL) and life satisfaction (LS). The purpose of this study was to assess differences between leisure-time PA and perceptions of both HRQoL and LS, as well as to assess differences between perceptions of both HRQoL and LS for Recreovía and non-Recreovía participants. Data were obtained using the baseline cross-sectional survey of 1533 participants (501 belonged to the intervention group) as part of the natural experiment Al Ritmo de las Comunidades. HRQoL was measured with the European Organization for Research and Treatment of Cancer 30-item questionnaire, LS was measured with Questions on Life Satisfaction Scale, and self-reported minutes of leisure-time PA were measured with the long version of the International Physical Activity Questionnaire. The mean age of participants was 41.7 years (standard deviation (SD) = 16.3). The participants had a good overall HRQoL and LS. The mean minutes of leisure-time PA were 158.1 min (SD = 230.2) a week. Results showed that those participants who reported higher leisure-time PA levels also reported a significantly higher LS (M = 41.9, SD = 35.0) relative to participants with lower levels (M = 37.6, SD = 34.2, t(1532) = -2.36, p < 0.01). There were no statistical differences in the perception of HRQoL and leisure-time PA ( t(1532) = -1.03, p = 0.30), although active people had higher scores. Both HRQoL and LS scores were higher in individuals who were participating in Recreovía ( p < 0.001). Higher LS scores were found in the group with higher leisure-time PA, while HRQoL showed no differences. Better psychological well-being indices were found in the Recreovía group.

Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students. To assess PA participation and constraints to participation among athletic training students. Cross-sectional study. Entry-level athletic training education programs (undergraduate and graduate) across the United States. Participants were 1125 entry-level athletic training students. Self-reported PA participation, including a calculated PA index based on a typical week. Leisure constraints and demographic data were also collected. Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation. Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits.

School-based physical education (PE) and physical activity (PA) policies can improve PA levels of students and promote health. Studies of policy implementation, communication, monitoring, enforcement, and evaluation are lacking. To describe how states implement, communicate, monitor, enforce, and evaluate key school-based PE and PA policies, researchers interviewed 24 key informants from state-level organizations in 9 states, including representatives from state departments of health and education, state boards of education, and advocacy/professional organizations. These states educate 27% of the US student population. Key informants described their organizations' roles in addressing 14 school-based PE and PA state laws and regulations identified by the Bridging the Gap research program and the National Cancer Institute's Classification of Laws Associated with School Students (C.L.A.S.S.) system. On average, states had 4 of 14 school-based PE and PA laws and regulations, and more than one-half of respondents reported different policies in practice besides the "on the books" laws. Respondents more often reported roles implementing and communicating policies compared with monitoring, enforcing, and evaluating them. Implementation and communication strategies used included training, technical assistance, and written communication of policy to local education agency administrators and teachers. State-level organizations have varying roles in addressing school-based PE and PA policies. Opportunities exist to focus state-level efforts on compliance with existing laws and regulations and evaluation of their impact.

Short-term physical activity (PA) has beneficial effects on symptom management and quality of life, however, longer-term adherence is likely needed for improved disease outcomes in breast cancer survivors (BCS). This study examined the effects of a supervised group exercise program on motivational outcomes and PA among BCS at 5-year follow-up. The original study was a two-armed, randomized controlled trial comparing a 12-week supervised group exercise program to usual care among 203 BCS. BCS for this follow-up study were contacted at 60 months postintervention and asked to complete assessments of motivational outcomes from the Theory of Planned Behavior and PA behavior using the Scottish Physical Activity Questionnaire. Overall, 87 participants provided 5-year follow-up data with no differences in participation by group. Analyses of covariance (ANCOVAs) revealed that supervised exercise had a significant positive effect on descriptive norm at 5-year follow-up (mean = +0.6; 95% CI = +0.1 to +1.1; d = +0.48; p = 0.021). Small positive effects were also noted for perceived behavioral control (d = +0.18), instrumental attitude (d = +0.26), and injunctive norm (d = +0.35), although they were not statistically significant. Moreover, BCS who were more active at 5-year follow-up also reported more favorable perceived behavioral control (d = +0.16), instrumental attitude (d = +0.28), injunctive norm (d = +0.24), and descriptive norm (d = +0.31), although these differences were not statistically significant. This trial provides suggestive evidence that a supervised exercise program has positive effects on motivational outcomes even after 5 years. Additional intervention strategies during follow-up may further improve long-term adherence and health outcomes in BCS. Copyright © 2014 Elsevier Ltd. All rights reserved.

Objective To determine if sarcopenia modulates the response to a physical activity intervention in functionally limited older adults. Design Secondary analysis of a randomized controlled trial. Setting Three academic centers. Participants Elders aged 70 to 89 years at risk for mobility disability who underwent dual-energy x-ray absorptiometry (DXA) for body composition at enrollment and follow-up at twelve months (N = 177). Intervention Subjects participated in a physical activity program (PA) featuring aerobic, strength, balance, and flexibility training, or a successful aging (SA) educational program about healthy aging. Measurements Sarcopenia as determined by measuring appendicular lean mass and adjusting for height and total body fat mass (residuals method), Short Physical Performance Battery score (SPPB), and gait speed determined on 400 meter course. Results At twelve months, sarcopenic and non-sarcopenic subjects in PA tended to have higher mean SPPB scores (8.7±0.5 and 8.7±0.2 points) compared to sarcopenic and non-sarcopenic subjects in SA (8.3±0.5 and 8.4±0.2 points, p = 0.24 and 0.10), although the differences were not statistically significant. At twelve months, faster mean gait speeds were observed in PA: 0.93±0.4 and 0.95±0.03 meters/second in sarcopenic and non-sarcopenic PA subjects, and 0.89±0.4 and 0.91±0.03 meters/second in sarcopenic and non-sarcopenic SA subjects (p = 0.98 and 0.26), although not statistically significant. There was no difference between the sarcopenic and non-sarcopenic groups in intervention adherence or number of adverse events. Conclusion These data suggest that older adults with sarcopenia, who represent a vulnerable segment of the elder population, are capable of improvements in physical performance after a physical activity intervention.

Physical activity (PA) has a protective role in cardiovascular diseases. To quantify PA in young adults and to correlate it with cardiovascular risk factors. A cross-sectional study was performed employing the international physical activity questionnaire (IPAQ), to measure the PA of 983 randomly selected young adults from Valparaiso region born between 1974 and 1978. Its results were associated with levels of obesity, insulin resistance and cardiovascular risk factors defined by the National Cholesterol Education Program-Adult Treatment Panel III (NCEP- ATP III) RESULTS: Mean physical activity among men and women was 3731 ± 3923 and 1360 ± 2303 METs-minutes/week, respectively (p < 0.001). Fifty percent of women and 21.5% of men had an insufficient level of physical activity (p < 0.001). Sixty percent of men and 23.4% of women had an intense level of physical activity (p < 0.001). There was an inverse association of physical activity and insulin resistance. A high physical activity was protective, specially among men, against a low HDL cholesterol level and high triglyceride levels with Odds Ratios of 0.59 (confidence interval (CI): 0,35-0.98) and 0.49 (CI: 0,27-0,87) respectively, after adjusting for body mass index and age. In this sample, men had higher levels of physical activity, that was protective against insulin resistance and the presence of cardiovascular risk factors.

Motivational interviewing (MI) is an evidence-based technique that enables clinicians to help patients modify health behaviors. Although MI is an essential tool for physician assistants (PAs), the extent to which it is addressed in PA curricula in the United States is unknown. This study is a comprehensive description of MI education in PA programs in the United States. Data are from the 2014 Physician Assistant Education Association Annual Program Survey. Descriptive statistics were conducted on de-identified data from all 186 PA programs in the United States. Of the 186 PA programs surveyed, 72.58% (n = 135) reported at least one course providing MI training. Availability of courses providing training in skills essential to the MI process varied. Having a course with verbal communication training was most frequently endorsed, and having a course with training in developing discrepancy was least frequently endorsed. The most popular teaching modality was lecture (84.95%, n = 158), whereas only 41.40% (n = 77) and 58.60% (n = 109) reported role play with evaluation and standardized patient exercises with evaluation, respectively. More than 70% of programs included at least one course in their curriculum that provided training in MI, suggesting that PA programs recognize the importance of MI. Instruction in change talk was not provided in nearly half of the programs. Role-play and standardized patient exercises with evaluation were underused methods despite their proven efficacy in MI education. As the first comprehensive benchmark of MI education for PAs, this study shows that although most programs address MI, opportunities exist to improve MI training in PA programs in the United States.

The aim of the Finnish Schools on the Move program is to create a more active and pleasant school day through physical activity (PA). In this quasi-experimental design, we compared changes in moderate-to-vigorous-intensity physical activity (MVPA) and sedentary time (ST) during the school day and outside school hours for Grades 1-9 over two academic years in four program schools and two reference schools. Altogether 319 girls and boys aged 7-15 participated in the study between 2010 and 2012. MVPA and ST were measured four times over the 1.5-year follow-up period for seven consecutive days, using a hip-worn ActiGraph accelerometer. Linear growth curve modeling was used to examine the effect of the program on MVPA and ST during follow-up. School day MVPA increased (P = 0.010) and school day ST decreased (P = 0.008) in program primary schools (Grades 1-6) more compared with the reference schools. The effect sizes (Cohen's d) for the difference in change (from the first to the last measurement) were small (d = 0.18 and d = -0.27, respectively). No differences in the changes of leisure-time or whole-day MVPA and ST between the program and reference schools were observed during follow-up. In conclusion, the changes in school day MVPA and ST did not translate into positive effects across the whole day. More effective and longer promotion actions are needed for positive changes in PA and ST, especially in lower secondary schools and for all daily segments. © 2016 The Authors.

Introduction Understanding the context where adolescents’ physical activity (PA) takes place could impact a more targeted approach to implement PA promotion and interventions in Africa. However, standardized data on adolescents’ PA behaviour is lacking in Nigeria. We described PA patterns in the various domains (home, school, transport, leisure-time) and intensity categories (light-intensity PA, moderate- to vigorous- intensity physical activity [MVPA] and total PA), and their associations with sociodemographic factors and socioeconomic status (SES) among secondary school adolescents in Nigeria. Methods A cross-sectional survey was conducted in a representative sample of 1006 secondary school adolescents (12–18 years, 50.4% girls) in Maiduguri, Nigeria. Self-reported PA was assessed with an adapted version of the Activity Questionnaire for Adolescents and Young Adults. Outcomes were weekly minutes (min/wk) of PA spent in the various domains and intensity categories. Multivariate ANOVA was used to examine associations of PA scores (domains and intensity levels) with adolescents’ sociodemographic characteristics and SES, and track differences in PA scores between subgroups. Results The total sample reported most PA at school (1525 min/wk), the least during active transportation (210 min/wk), and only 37% engaged in 60 min of MVPA daily. Boys reported significantly more leisure-time PA (P<0.001), active transportation (P<0.001), MVPA (P = 0.023) and total PA (P = 0.003) than girls, while girls reported more school-based PA (P = 0.009), home-based PA (P<0.001) and light-intensity PA (P<0.001) than boys. Moderate-intensity PA (P = 0.024) and total PA (P = 0.049) were significantly higher in younger age group than in older group. Household car ownership was associated with less active transportation (P = 0.009), less moderate-intensity PA (P = 0.048) and with more leisure-time PA (P = 0.013). High parental SES was associated with more leisure-time PA (P = 0.002), more MVPA (P = 0.047) and less active transportation (P<0.001). Adolescents of various weight status differed significantly in their leisure-time PA (P<0.001), moderate-intensity PA (P = 0.011) and total PA (P = 0.033). Conclusions The patterns and levels of physical activity among adolescents in Nigeria vary according to the adolescents’ age, gender, weight status and SES. These findings have important public health implications for identifying subgroups of Nigerian adolescents that should be targeted for effective physical activity promoting interventions.

The purpose of this study was to evaluate the validity and interrater reliability of the Observational System for Recording Activity in Children: Youth Sports (OSRAC:YS). Children (N = 29) participating in a parks and recreation soccer program were observed during regularly scheduled practices. Physical activity (PA) intensity and contextual factors were recorded by momentary time-sampling procedures (10-second observe, 20-second record). Two observers simultaneously observed and recorded children's PA intensity, practice context, social context, coach behavior, and coach proximity. Interrater reliability was based on agreement (Kappa) between the observer's coding for each category, and the Intraclass Correlation Coefficient (ICC) for percent of time spent in MVPA. Validity was assessed by calculating the correlation between OSRAC:YS estimated and objectively measured MVPA. Kappa statistics for each category demonstrated substantial to almost perfect interobserver agreement (Kappa = 0.67-0.93). The ICC for percent time in MVPA was 0.76 (95% C.I. = 0.49-0.90). A significant correlation (r = .73) was observed for MVPA recorded by observation and MVPA measured via accelerometry. The results indicate the OSRAC:YS is a reliable and valid tool for measuring children's PA and contextual factors during a youth soccer practice.

Increasing mental load and inadequate stress management significantly affect the efficiency, success and safety of the educational/working process in adolescents. The objective of this study is to determine the extent that adolescents compensate for their school mental load by physical activity (PA) on weekend days and, thus, to contribute to the objective measurement of mental load in natural working conditions. A cross-sectional study was conducted between September 2013 and April 2014. A set of different methods was employed-self-administered questionnaire (IPAQ-long questionnaire), objective measurements-pedometers, and accelerometers (ActiTrainers). They was distributed to 548 students from 17 high schools. Participants' mental load was assessed based on the difference between PA intensity and/or physical inactivity and heart rate range. The participants with the highest mental load during school lessons do not compensate for this load by PA on weekend days. Adolescents need to be encouraged to be aware of their subjective mental load and to intentionally compensate for this load by PA on weekend days. It is necessary to support the process of adopting habits by sufficient physical literacy of students, as well as teachers, and by changes in the school program.

Regulation of intrapleural fibrinolysis by urokinase-α-macroglobulin complexes in tetracycline-induced pleural injury in rabbits

2009-01-01

The proenzyme single-chain urokinase plasminogen activator (scuPA) more effectively resolved intrapleural loculations in rabbits with tetracycline (TCN)-induced loculation than a range of clinical doses of two-chain uPA (Abbokinase) and demonstrated a trend toward greater efficacy than single-chain tPA (Activase) (Idell S et al., Exp Lung Res 33: 419, 2007.). scuPA more slowly generates durable intrapleural fibrinolytic activity than Abbokinase or Activase, but the interactions of these agents with inhibitors in pleural fluids (PFs) have been poorly understood. PFs from rabbits with TCN-induced pleural injury treated with intrapleural scuPA, its inactive Ser195Ala mutant, Abbokinase, Activase, or vehicle, were analyzed to define the mechanism by which scuPA induces durable fibrinolysis. uPA activity was elevated in PFs of animals treated with scuPA, correlated with the ability to clear pleural loculations, and resisted (70–80%) inhibition by PAI-1. α-macroglobulin (αM) but not urokinase receptor complexes immunoprecipitated from PFs of scuPA-treated rabbits retained uPA activity that resists PAI-1 and activates plasminogen. Conversely, little plasminogen activating or enzymatic activity resistant to PAI-1 was detectable in PFs of rabbits treated with Abbokinase or Activase. Consistent with these findings, PAI-1 interacts with scuPA much slower than with Activase or Abbokinase in vitro. An equilibrium between active and inactive scuPA (kon = 4.3 h−1) limits the rate of its inactivation by PAI-1, favoring formation of complexes with αM. These observations define a newly recognized mechanism that promotes durable intrapleural fibrinolysis via formation of αM/uPA complexes. These complexes promote uPA-mediated plasminogen activation in scuPA-treated rabbits with TCN-induced pleural injury. PMID:19666776

Federal guidelines state that youth should participate in a variety of physical activity (PA) they find enjoyable. Little is known, however, about how variety and enjoyment are associated with PA participation among adolescents. Data came from the 2010 National Youth Physical Activity and Nutrition Survey, a nationally representative survey of adolescents. Path analysis was used to examine the association of a variety of self-reported PA, defined as the number of activities and activity types (ie, team sports/weightlifting, individual activities, and other competitive/recreational sports), on self-reported PA enjoyment and participation. The analysis also examined whether enjoyment mediates the association between a variety of PA and participation. Separate models were estimated for boys and girls. Number of activities was associated with increased PA enjoyment and participation. For boys and girls, team sports/weightlifting was associated with increased participation, and individual activities were indirectly associated with increased participation through enjoyment. For boys, team sports/weightlifting was indirectly related with participation. These findings suggest that participation in a variety of PA is associated with increased PA enjoyment and participation. Providing opportunities for adolescents to engage in a variety of activities might help them identify PA they enjoy and facilitate lifelong PA habits.

To analyse the effects of 1 year of participation in a physical activity (PA) program linked to a health-care setting on physical fitness (PF) and health-related quality of life (HRQoL) and to determine the relationships between PA, PF and HRQoL in middle-aged and older adults. In total, 3214 participants were recruited from a health-care setting. Sociodemographic data, HRQoL questionnaires and PF tests were applied by 37 employees at baseline and 1 year later. The participants were placed in an exercise group (EG) (n = 2614) and the remaining participants (n = 600) were placed in the control group (CG). EG performed the program 3 days/week for 50-60 minutes per session involving brisk walking with intermittent flexibility, strength and balance activities/exercises.CG participants were asked to continue with their usual activities. Data analysis included repeated measures analysis of variance, linear regression and contingency analysis. EG showed significant mild-moderate improvement in all PF and HRQoL outcomes, especially in adjusted models. Changes in several PF variables were predictive of HRQoL changes. EG exhibited either improvements or no change in HRQoL dimensions. CG exhibited no change or declines in all dimensions. PF is positively related with HRQoL. PA significantly improved PF, especially the PF components more impaired at baseline. © The Author 2015. Published by Oxford University Press on behalf of the European Public Health Association.

Socioeconomic health inequalities are partly attributed to different physical activity (PA) patterns. Psychosocial factors interacting with PA are suggested to explain the socioeconomic differences in PA to some extent. The aim of the present study was to examine whether PA self-efficacy, PA social support, and general self-control contribute to the socioeconomic status (SES) differences in leisure time physical activity (LTPA) and in total PA. The sample consisted of 25-74-year-old Finnish men (n = 2325) and women (n = 2699), who participated in the cross-sectional FINRISK Study in 2007. Physical activity was measured as total PA (MET-h/week) and as LTPA (inactive/active). A psychosocial factor questionnaire included scales measuring PA self-efficacy, PA social support, and general self-control. SES was defined by household gross income and years of education. Both higher education and income were associated with higher levels of LTPA, whereas total PA was higher among those with lower SES. Subjects with high SES reported higher levels of PA self-efficacy and PA social support, but general self-control correlated only with higher income. PA self-efficacy, PA social support and general self-control had positive associations with both LTPA and total PA. These psychosocial factors partly explained the SES differences in LTPA, but not in total PA. Future intervention studies should examine whether, by influencing PA self-efficacy, PA social support, and general self-control, it is possible to diminish the SES differences in PA.

Few studies have examined how young adult cancer survivors use online social media. The objective of this study was to characterize Facebook engagement by young adult cancer survivors in the context of a physical activity (PA) intervention program. Young adult cancer survivors participated in one of two Facebook groups as part of a 12-week randomized trial of a PA intervention (FITNET) compared to a self-help comparison (SC) condition. A moderator actively prompted group discussions in the FITNET Facebook group, while social interaction was unprompted in the SC group. We examined factors related to engagement, differences in engagement by group format and types of Facebook posts, and the relationship between Facebook engagement and PA outcomes. There were no group differences in the number of Facebook comments posted over 12 weeks (FITNET, 153 vs. SC, 188 p = 0.85) or the proportion of participants that reported engaging within Facebook group discussions at least 1-2 days/week. The proportion of participants that made any posts decreased over time in both groups. SC participants were more likely than FITNET participants to agree that group discussions caused them to become physically active (p = 0.040) and that group members were supportive (p = 0.028). Participant-initiated posts elicited significantly more comments and likes than moderator-initiated posts. Responses posted on Facebook were significantly associated with light PA at 12 weeks (β = 11.77, t(85) = 1.996, p = 0.049) across groups. Engagement within Facebook groups was variable and may be associated with PA among young adult cancer survivors. Future research should explore how to promote sustained engagement in online social networks. ClinicalTrials.gov identifier: NCT01349153.

Unfavorable lipid profile is associated with developed cardiovascular diseases. It is necessary to know the beneficial effects of different mode exercises to improve lipid profile. To investigate, in obese men and women, the effect on lipid profile of hypocaloric diet combined with structured exercise programs or recommendations of physical activity. Ninety six obese subjects (59 women and 61 men; 18 - 50 years; BMI >30 and < 34.9 kg/m(2)) were randomised into four supervised treatment groups: strength training (S; n = 24), endurance training (E; n = 26), combined S + E (SE; n = 24), and and received recommendations of physical activity (PA; n = 22). Energy intake, body composition, training variables (VO(2peak), strength index, dynamometric strength index) and blood lipid profile were recorded at baseline and after 24 weeks of treatment. Blood lipid profile improved in all groups. No statistically significant differences in baseline and posttraining values were observed between groups. HDLCholesterol showed no changes. A decrease in LDLCholesterol values was observed in all groups after the intervention (S: 11.2%, E: 10.8%, SE: 7.9%, PA: 10.8%; p < 0.01). S, E and PA subjects showed decrease in triglycerides (S: 14.9%, E: 15.8%, PA: 15.7%; p < 0.01). Total cholesterol decreased in all groups (S: 8.4%, p < 0.01; E: 8.8%, p < 0.01; SE: 4.9%, p < 0.01; PA: 8.3%, p < 0.05). All protocols proposed in our study improved blood lipid profile in obese people. There were no significant differences about the effect on the lipid profile between the implementation of a structured training protocol with physical activity professional supervision and follow recommendations of physical activity.

Children classified as overweight or obese and those with disabilities are at a greater risk of not meeting the minimum recommendation of 60 min a day of moderate to vigorous physical activity (PA). Youth with Prader-Willi Syndrome (PWS) appear to participate in less PA compared to nonsyndromal children, likely due to syndrome-related factors. However, description of PA patterns in youth with PWS is lacking. The purpose of this study was to characterize PA in youth with PWS and to compare it to PA in children with nonsyndromal obesity. Twenty-four youth with PWS (ages 8-16 years) and 40 obese children without PWS (OB) (ages 8-11 years) wore accelerometers for eight consecutive days. Data were screened for compliance and classified into PA intensities: sedentary behavior (SED), light (LPA), moderate (MPA), vigorous (VPA) and moderate plus vigorous (MVPA). Youth with PWS spent 19.4% less time in weekly LPA (p=0.007) and 29.8% less time in weekly VPA compared to OB controls (p=0.036). All other intensities were similar between groups. In addition, PWS participated in less LPA and VPA during the weekends compared to OB, and less LPA on weekdays when compared to OB. There was also a trend towards PWS participating in less MVPA during the weekends and less VPA during the weekends than OB controls. There was a trend towards PWS participating in less VPA on weekends compared to weekdays, while OB participated similarly in VPA on weekdays and weekend days. On average, neither PWS nor OB children met minimum MVPA recommendations. The results suggest there is a need to design exercise programs for PWS youth that focus on integrating vigorous intensity activities, especially during the weekends when structured PA may not be available.

Facilitating Research in Physician Assistant Programs: Creating a Student-Level Longitudinal Database.

PubMed

Morgan, Perri; Humeniuk, Katherine M; Everett, Christine M

2015-09-01

As physician assistant (PA) roles expand and diversify in the United States and around the world, there is a pressing need for research that illuminates how PAs may best be selected, educated, and used in health systems to maximize their potential contributions to health. Physician assistant education programs are well positioned to advance this research by collecting and organizing data on applicants, students, and graduates. Our PA program is creating a permanent longitudinal education database for research that contains extensive student-level data. This database will allow us to conduct research on all phases of PA education, from admission processes through the professional practice of our graduates. In this article, we describe our approach to constructing a longitudinal student-level research database and discuss the strengths and limitations of longitudinal databases for research on education and the practice of PAs. We hope to encourage other PA programs to initiate similar projects so that, in the future, data can be combined for use in multi-institutional research that can contribute to improved education for PA students across programs.

The immunomodulatory effects of Physalis angulata L. extract fraction VII (PA-VII), PA-VII-A, PA-VII-B and PA-VII-C were investigated in this study. The results showed that PA-VII and PA-VII-C strongly enhanced blastogenesis response, PA-VII-B had moderate activity, and PA-VII-A exerted only slight effect on cell proliferation. A synergistic effect was observed when the suboptimal dosage of phytohemagglutinin (PHA) or lipopolysaccharide (LPS) was added to the culture. Furthermore, PA-VII and PA-VII-C possessed stimulatory activity on B cells and less effect on T cells. The antibody responses were also augmented by PA-VII, PA-VII-B and PA-VII-C, but not by PA-VII-A. The enhancement of antibody response could be observed both in BALB/c and C3H/HeJ mice.

The PA profession is 50 years young. Practicing PAs and current students hail from several generational categories ranging from Builders to Generation Z. This article reviews how different generations may have experienced PA program expansion, professional identity, state licensing, and prescription delegation. The authors sampled a cohort of PA program applicants about their views on what evokes optimism and concern for the PA profession. These themes mirror the recently paved professional road, while posing the all-important question: What construction lies on the horizon?

Physical activity (PA) is enjoyable, but there are barriers to participation. TV viewing is highly enjoyable with limited barriers. Exercising while viewing TV may impact enjoyment, exercise self-efficacy, and barriers to PA, compared with exercising without TV. 58 sedentary, overweight adults were randomized to 1 of 2 PA prescriptions: one that increased PA during TV viewing (TV Commercial Stepping), and another that focused solely on PA (Walking). Random effects models tested changes in enjoyment of TV and PA, exercise self-efficacy, and barriers to PA across time (baseline, 3, and 6 months) and PA prescription during a 6-month PA intervention. At baseline, TV was more enjoyable than PA. Over the 6-month intervention, enjoyment of TV viewing did not change, but enjoyment of PA and exercise self-efficacy significantly increased, while barriers to PA significantly decreased for both groups compared with baseline (P < .05). While enjoyment of TV viewing remained constant, PA became more enjoyable, confidence to exercise increased, and barriers to being active were reduced for previously sedentary adults participating in a behavioral PA intervention. These findings highlight the importance of encouraging inactive adults to engage in some form of PA, whether it occurs with or without TV viewing.

Self-determined motivation towards physical activity in adolescents treated for obesity: an observational study

PubMed Central

2011-01-01

Background Within the Self-Determination Theory (SDT) framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between physical activity (PA) and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m2, 15.1 ± 1.5 years, 62% girls). A subsample of 65 adolescents (stratified by educational level) were divided into low (n = 34) versus high educated (n = 31) as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p < 0.001), introjected (r = 0.23, p < 0.01), identified (r = 0.31, p < 0.001) and intrinsic regulation (r = 0.38, p < 0.001). Higher educated adolescents scored higher on the composite score of relative autonomy, introjected, identified and intrinsic regulation at the start of treatment (F = 3.68, p < 0.001). The composite score of relative autonomy, external, identified and intrinsic regulation significantly increased during treatment for all adolescents (F = 6.65, p < 0.001). Introjected regulation significantly increased for lower educated adolescents (F = 25.57, p < 0.001). Conclusions The BREQ-2 can be used in an obese adolescent population. Higher levels of autonomous motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment. Special attention for lower educated adolescents during treatment is needed, as they have a lower autonomous motivation at the start of treatment and an increase in introjected regulation during treatment.

The objective of this study was to investigate the effect of a 4-year specialist-taught Physical Education (PE) program on physical activity (PA) among primary school children. A 4-year cluster randomised controlled trial was conducted in children (initially aged 8 years) from 29 primary schools (13 Intervention, 16 Control). Intervention students (N = 457) received 2 × 45 min PE lessons per week from specialist-trained PE teachers (68 lessons per year, 272 lessons over 4 years). Control group students (N = 396) received usual practice PE from generalist classroom teachers. PA during PE lessons was examined using the System for Observing Fitness Instruction Time (SOFIT). Pedometers (steps/day) were worn for 7 days each year, and accelerometers were worn concurrently in the final two years to assess moderate to vigorous (MVPA) and sedentary activity. Linear and generalized mixed models were used to determine differences in Intervention and Control student PA and the proportion of students meeting PA guidelines. The intervention increased SOFIT-observed student MVPA during PE lessons by 6.5 mins (16.7 v 10.2, p < 0.001). Within intervention schools, participants increased their whole-day step counts (boys = 449 [CI,140 to 756]; girls = 424 [CI,222 to 626]) and minutes of MVPA (boys = 8.0 [CI,6.8 to 9.2]; girls = 3.5 [CI,1.7 to 5.4]) on PE days. However, compared to the Control group the Intervention did not: increase habitual steps/day or MVPA when averaged over 7 days; elicit greater improvements in these measures over time; or increase the odds of meeting step/day or MVPA recommendations. At age 11 years Intervention group boys were 20 mins less sedentary per day (380 [CI,369 to 391] vs 360 [CI,350 to 369]) and this effect was sustained at age 12 years. Well-designed specialist-taught PE can improve student PA during PE lessons. However for PE to be a significant contributor to improving habitual PA in pre-adolescent children, daily classes are likely to be required, and even this would need to be supplemented with a wider multicomponent strategy. Our finding of a reduction in sedentary time among Intervention boys warrants further investigation into the potential role PE could play in influencing sedentary behaviour.

Physical activity (PA) is positively associated with numerous health benefits among cancer survivors. This study examined insufficiently investigated relationships among PA, health-related quality of life (HRQOL), and bowel function (BF) in rectal cancer survivors. RC survivors (n = 1063) ≥5 years from diagnosis in two Kaiser permanente regions were mailed a multidimensional survey to assess HRQOL and BF. PA was assessed by a modified Godin Leisure-Time Exercise Questionnaire. PA minutes were categorized into weighted categories based on guidelines: (1) not active (zero PA minutes); (2) insufficiently active (1-149 PA minutes); (3) meeting guidelines (150-299 PA minutes); and (4) above guidelines (≥300 PA minutes). Relationships of PA with HRQOL and BF were evaluated using multiple linear regression, stratified by sex and ostomy status for BF. Types of PA identified as helpful for BF and symptoms addressed were summarized. Response rate was 60.5%. Of 557 participants, 40% met or exceeded PA guidelines, 34% were not active, and 26% were insufficiently active. Aerobic activities, specifically walking and cycling, were most commonly reported to help BF. Higher PA was associated with better psychological wellbeing and multiple SF12 scales, worse BF scores in men with ostomies, and better BF scores in women. Meeting or exceeding PA guidelines was associated with higher HRQOL. Although the BF findings are exploratory, they suggest women may benefit from increased PA, whereas men with ostomies may face challenges that require more study. Identifying PA strategies that will lead to improved patient compliance and benefit are needed.

PLAYgrounds: Effect of a PE playground program in primary schools on PA levels during recess in 6 to 12 year old children. Design of a prospective controlled trial

PubMed Central

2011-01-01

Background The relative number of children meeting the minimal required dose of daily physical activity remains execrably low. It has been estimated that in 2015 one out of five children will be overweight. Therefore, low levels of physical activity during early childhood may compromise the current and future health and well-being of the population, and promoting physical activity in younger children is a major public health priority. This study is to gain insight into effects of a Physical Education based playground program on the PA levels during recess in primary school children aged 6-12. Methods/design The effectiveness of the intervention program will be evaluated using a prospective controlled trial design in which schools will be matched, with a follow-up of one school year. The research population will consist of 6-12 year old primary school children. The intervention program will be aimed at improving physical activity levels and will consist of a multi-component alteration of the schools' playground. In addition, playground usage will be increased through altered time management of recess times, as well as a modification of the Physical Education content. Discussion The effects of the intervention on physical activity levels during recess (primary outcome measure), overall daily physical activity and changes in physical fitness (secondary outcome measures) will be assessed. Results of this study could possibly lead to changes in the current playground system of primary schools and provide structured health promotion for future public health.

Simultaneous ablation of the two known activators of plasminogen (Plg), urokinase-type (uPA) and the tissue-type (tPA), results in a substantial delay in skin wound healing. However, wound closure and epidermal re-epithelialization are significantly less impaired in uPA;tPA double-deficient mice than in Plg-deficient mice. Skin wounds in uPA;tPA-deficient mice treated with the broad-spectrum matrix metalloproteinase (MMP) inhibitor galardin (N-[(2R)-2-(hydroxamido-carbonylmethyl)-4-methylpentanoyl]-L-tryptophan methylamide) eventually heal, whereas skin wounds in galardin-treated Plg-deficient mice do not heal. Furthermore, plasmin is biochemically detectable in wound extracts from uPA;tPA double-deficient mice. In vivo administration of a plasma kallikrein (pKal)-selective form of the serine protease inhibitor ecotin exacerbates the healing impairment of uPA;tPA double-deficient wounds to a degree indistinguishable from that observed in Plg-deficient mice, and completely blocks the activity of pKal, but not uPA and tPA in wound extracts. These findings demonstrate that an additional plasminogen activator provides sufficient plasmin activity to sustain the healing process albeit at decreased speed in the absence of uPA, tPA and galardin-sensitive MMPs and suggest that pKal plays a role in plasmin generation.

The Unfolded Protein Response Plays a Predominant Homeostatic Role in Response to Mitochondrial Stress in Pancreatic Stellate Cells

PubMed Central

Su, Hsin-Yuan; Waldron, Richard T.; Gong, Raymond; Ramanujan, V. Krishnan; Pandol, Stephen J.; Lugea, Aurelia

2016-01-01

Activated pancreatic stellate cells (PaSC) are key participants in the stroma of pancreatic cancer, secreting extracellular matrix proteins and inflammatory mediators. Tumors are poorly vascularized, creating metabolic stress conditions in cancer and stromal cells that necessitate adaptive homeostatic cellular programs. Activation of autophagy and the endoplasmic reticulum unfolded protein response (UPR) have been described in hepatic stellate cells, but the role of these processes in PaSC responses to metabolic stress is unknown. We reported that the PI3K/mTOR pathway, which AMPK can regulate through multiple inputs, modulates PaSC activation and fibrogenic potential. Here, using primary and immortalized mouse PaSC, we assess the relative contributions of AMPK/mTOR signaling, autophagy and the UPR to cell fate responses during metabolic stress induced by mitochondrial dysfunction. The mitochondrial uncoupler rottlerin at low doses (0.5–2.5 μM) was added to cells cultured in 10% FBS complete media. Mitochondria rapidly depolarized, followed by altered mitochondrial dynamics and decreased cellular ATP levels. This mitochondrial dysfunction elicited rapid, sustained AMPK activation, mTOR pathway inhibition, and blockade of autophagic flux. Rottlerin treatment also induced rapid, sustained PERK/CHOP UPR signaling. Subsequently, high doses (>5 μM) induced loss of cell viability and cell death. Interestingly, AMPK knock-down using siRNA did not prevent rottlerin-induced mTOR inhibition, autophagy, or CHOP upregulation, suggesting that AMPK is dispensable for these responses. Moreover, CHOP genetic deletion, but not AMPK knock-down, prevented rottlerin-induced apoptosis and supported cell survival, suggesting that UPR signaling is a major modulator of cell fate in PaSC during metabolic stress. Further, short-term rottlerin treatment reduced both PaSC fibrogenic potential and IL-6 mRNA expression. In contrast, expression levels of the angiogenic factors HGF and VEGFα were unaffected, and the immune modulator IL-4 was markedly upregulated. These data imply that metabolic stress-induced PaSC reprogramming differentially modulates neighboring cells in the tumor microenvironment. PMID:26849807

Purpose Over half of young adult cancer survivors do not meet physical activity (PA) guidelines. PA interventions can enhance health and quality of life among young adult cancer survivors. However, few exercise interventions have been designed and tested in this population. This study evaluated the feasibility and preliminary efficacy of a 12-week, Facebook-based intervention (FITNET) aimed at increasing moderate-to-vigorous intensity PA compared to a Facebook-based self-help comparison (SC) condition. Methods Young adult cancer survivors (n=86) were randomly assigned to the FITNET or SC group. All participants were asked to complete self-administered online questionnaires at baseline and after 12 weeks. Results Seventy-seven percent of participants completed post-intervention assessments, and most participants reported using intervention components as intended. Participants in both groups would recommend the program to other young adult cancer survivors (FITNET: 46.9% vs. SC: 61.8%; p=0.225). Over 12 weeks, both groups increased self-reported weekly minutes of moderate-to-vigorous PA (FITNET: 67 minutes/week, p=0.009 vs. SC: 46 minutes/week, p=0.045), with no significant difference between groups. Increases in light PA were 135 minutes/week greater in the FITNET group relative to the SC group (p=0.032), and the FITNET group reported significant weight loss over time (−2.1 kg, p=0.004; p=0.083 between groups). Conclusions Facebook-based intervention approaches demonstrated potential for increasing PA in young adult cancer survivors. Implications for Cancer Survivors Social networking sites may be a feasible way for young adult cancer survivors to receive health information and support to promote PA and healthy behaviors.

Over half of young adult cancer survivors do not meet physical activity (PA) guidelines. PA interventions can enhance health and quality of life among young adult cancer survivors. However, few exercise interventions have been designed and tested in this population. This study evaluated the feasibility and preliminary efficacy of a 12-week, Facebook-based intervention (FITNET) aimed at increasing moderate-to-vigorous intensity PA compared with a Facebook-based self-help comparison (SC) condition. Young adult cancer survivors (n = 86) were randomly assigned to the FITNET or SC group. All participants were asked to complete self-administered online questionnaires at baseline and after 12 weeks. Seventy-seven percent of participants completed postintervention assessments, and most participants reported using intervention components as intended. Participants in both groups would recommend the program to other young adult cancer survivors (FITNET, 46.9 vs. SC, 61.8 %; p = 0.225). Over 12 weeks, both groups increased self-reported weekly minutes of moderate-to-vigorous PA (FITNET, 67 min/week (p = 0.009) vs. SC, 46 min/week (p = 0.045)), with no significant difference between groups. Increases in light PA were 135 min/week greater in the FITNET group relative to the SC group (p = 0.032), and the FITNET group reported significant weight loss over time (-2.1 kg, p = 0.004; p = 0.083 between groups). Facebook-based intervention approaches demonstrated potential for increasing PA in young adult cancer survivors. Social networking sites may be a feasible way for young adult cancer survivors to receive health information and support to promote PA and healthy behaviors.

Physical activity (PA) is recommended for stable patients with advanced heart failure (HF). We evaluated expected health benefits of PA and social support as facilitators of PA, and physical symptom distress and psychological distress (depression, anxiety) as barriers to PA. Additionally, we investigated if facilitators of PA are of particular importance for patients who report barriers. We analyzed data assessed at time of waitlisting in 231 ambulatory patients (53.4 ± 10.3 years, 18 % women) who were enrolled in the multisite Waiting for a New Heart Study in 1 Austrian and 16 German hospitals. Self-reported everyday PA scores (number of activities, duration of activities) was regressed on demographic characteristics and indicators of disease severity (ejection fraction, peak oxygen consumption), facilitators (expected health benefits of PA, perceived emotional support, perceived support for PA), and barriers to PA (physical symptom distress, psychological distress). Interaction terms of facilitators with barriers were also examined. PA was positively associated with higher peak oxygen consumption, validating self-reported PA. Regarding facilitators, expected health benefits of PA were independently associated with higher PA (p values < 0.001). There were no main effects for social support on PA. Regarding barriers, depression tended to be associated with fewer activities (p = 0.068). However, in the presence of barriers (depression, physical symptoms), feeling supported for being physically active was positively associated with PA (p values < 0.05). Interventions to improve PA may benefit from strengthening positive expectations of health outcomes associated with everyday PA and fostering PA-specific social support for those distressed by HF symptoms or depression.

Reciprocal Reinforcement Between Wearable Activity Trackers and Social Network Services in Influencing Physical Activity Behaviors

PubMed Central

2016-01-01

Background Wearable activity trackers (WATs) are emerging consumer electronic devices designed to support physical activities (PAs), which are based on successful behavior change techniques focusing on goal-setting and frequent behavioral feedbacks. Despite their utility, data from both recent academic and market research have indicated high attrition rates of WAT users. Concurrently, evidence shows that social support (SS), delivered/obtained via social network services or sites (SNS), could increase adherence and engagement of PA intervention programs. To date, relatively few studies have looked at how WATs and SS may interact and affect PAs. Objective The purpose of this study was to explore how these two Internet and mobile technologies, WATs and SNS, could work together to foster sustainable PA behavior changes and habits among middle-aged adults (40-60 years old) in Taiwan. Methods We used purposive sampling of Executive MBA Students from National Taiwan University of Science and Technology to participate in our qualitative research. In-depth interviews and focus groups were conducted with a total of 15 participants, including 9 WAT users and 6 nonusers. Analysis of the collected materials was done inductively using the thematic approach with no preset categories. Two authors from different professional backgrounds independently annotated and coded the transcripts, and then discussed and debated until consensus was reached on the final themes. Results The thematic analysis revealed six themes: (1) WATs provided more awareness than motivation in PA with goal-setting and progress monitoring, (2) SS, delivered/obtained via SNS, increased users’ adherence and engagement with WATs and vice versa, (3) a broad spectrum of configurations would be needed to deliver WATs with appropriately integrated SS functions, (4) WAT design, style, and appearance mattered even more than those of smartphones, as they are body-worn devices, (5) the user interfaces of WATs left a great deal to be desired, and (6) privacy concerns must be addressed before more mainstream consumers would consider adopting WATs. Conclusions Participants perceived WATs as an awareness tool to understand one’s PA level. It is evident from our study that SS, derived from SNS and other pertinent vehicles such as the LINE social messaging application (similar to WhatsApp and WeChat), will increase the engagement and adherence of WAT usage. Combining WATs and SNS enables cost-effective, scalable PA intervention programs with end-to-end services and data analytics capabilities, to elevate WATs from one-size-fits-all consumer electronics to personalized PA assistants.

Background Federal guidelines state that youth should participate in a variety of physical activity (PA) they find enjoyable. Little is known, however, about how variety and enjoyment are associated with PA participation among adolescents. Methods Data came from the 2010 National Youth Physical Activity and Nutrition Survey, a nationally representative survey of adolescents. Path analysis was used to examine the association of a variety of self-reported PA, defined as the number of activities and activity types (ie, team sports/weightlifting, individual activities, and other competitive/recreational sports), on self-reported PA enjoyment and participation. The analysis also examined whether enjoyment mediates the association between a variety of PA and participation. Separate models were estimated for boys and girls. Results Number of activities was associated with increased PA enjoyment and participation. For boys and girls, team sports/weightlifting was associated with increased participation, and individual activities were indirectly associated with increased participation through enjoyment. For boys, team sports/weightlifting was indirectly related with participation. Conclusions These findings suggest that participation in a variety of PA is associated with increased PA enjoyment and participation. Providing opportunities for adolescents to engage in a variety of activities might help them identify PA they enjoy and facilitate lifelong PA habits. PMID:26107142

Little is known about physical activity (PA) in the very old, the fastest growing age group in the population. We aimed to examine the convergent validity of subjective and objective measures of PA in adults aged over 85 years. A total of 484 participants aged 87-89 years recruited to the Newcastle 85+ study completed a purpose-designed physical activity questionnaire (PAQ), which categorised participants as mildly active, moderately active and very active. Out of them, 337 participants wore a triaxial, raw accelerometer on the right wrist over a 5-7-day period to obtain objective measures of rest/activity, PA intensity and PA type. Data from subjective and objective measurement methods were compared. Self-reported PA was significantly associated with objective measures of the daily sedentary time, low-intensity PA and activity type classified as sedentary, activities of daily living and walking. Objective measures of PA were significantly different when low, moderate and high self-reported PA categories were compared (all P < 0.001). The Newcastle 85+ PAQ demonstrated convergent validity with objective measures of PA. Our findings suggest that this PAQ can be used in the very old to rank individuals according to their level of total PA. © The Author 2015.

To implement appropriate programs for promoting physical activity (PA) in people who are Deaf, it is important to have valid instruments for assessing PA in this population. The main purpose of this study was to examine the criterion validity of the short form of the International Physical Activity Questionnaire (IPAQ-S) in Deaf adults. This study included 44 adults (18-65 years) of both genders (63.6% were females) who met the inclusion criteria. Objective measures of PA were collected using accelerometers, which were worn by each participant during one week. After using the accelerometer, the IPAQ-S was applied to assess participants' physical activity during the last 7 days. There was no significant correlation between the average time spent in moderate to vigorous physical activity (MVPA) as measured by the accelerometer (40.1 ± 24.5 min/day) and by the IPAQ-S (41.3 ± 57.5 min/day). The IPAQ-S significantly underestimated the time spent in sedentary behavior (7.6 ± 2.7 h/day vs. 10.1 ± 1.6 h/day). Sedentary behavior and MVPA as measured by the accelerometer and the IPAQ-S showed limited agreement. Our results show some limitations on the use of IPAQ-S for quantifying PA among adults who are Deaf. The IPAQ-S tends to overestimate the MVPA and to underestimate sedentary behavior in adults who are Deaf. Copyright © 2016 Elsevier Inc. All rights reserved.

The school setting provides a promising environment to increase children's physical activity (PA), however, staff often impact the success of PA within schools. The purpose of this article was to describe the knowledge of elementary school staff related to PA and their perception of the importance of the school environment being conducive to PA prior to the implementation of a recess intervention. Qualitative focus groups were conducted in 12 elementary schools in the Midwest. Grounded theory was used to explore participants' knowledge and perceptions. Participants felt PA was important but believed several factors impacted children's ability to be more active: (i) lack of time due to increasing academic demands, (ii) peer pressure (especially in girls) not to be active and (iii) lack of space and equipment. When discussing recess, staff felt that their encouragement of or active participation in PA with children resulted in more activity. Furthermore, even though participants were aware of PA benefits, they noticed eliminating recess was often used as a punishment for misbehavior. School-based PA promotion and PA opportunities hold great promise for increasing PA in children. However, to maximize these efforts school polices related to training staff about PA are needed.

Background Numerous studies report that bariatric surgery patients report more physical activity (PA) after surgery than before, but the quality of PA assessment has been questionable. Methods The Longitudinal Assessment of Bariatric Surgery-2 is a 10-center longitudinal study of adults undergoing bariatric surgery. Of 2458 participants, 455 were given an activity monitor, which records steps/minute, and an exercise diary before and 1 year after surgery. Mean step/day, active minutes/day, and high-cadence minutes/week were calculated for 310 participants who wore the monitor at least 10 hours/day for at least 3 days at both time points. Pre- and post-surgery PA were compared for differences using the Wilcoxon signed-rank test. Generalized Estimating Equations identified independent pre-operative predictors of post-operative PA. Results PA increased significantly (p<.0001) pre- to post-operative for all PA measures. Median values pre- and post-operative were: 7563 and 8788 steps/day; 309 and 340 active minutes/day; and 72 and 112 high-cadence minutes/week, respectively. However, depending on the PA measure, 24–29% of participants were at least 5% less active post-operative than pre-operative. Controlling for surgical procedure, sex, age and BMI, higher PA preoperative independently predicted higher PA post-operative (p<.0001, all PA measures). Less pain, not having asthma and self-report of increasing PA as a weight loss strategy pre-operative also independently predicted more high-cadence minutes/week post-operative (p<.05). Conclusion The majority of adults increase their PA level following bariatric surgery. However, most remain insufficiently active and some become less active. Increasing PA, addressing pain and treating asthma prior to surgery may have a positive impact on post-operative PA. PMID:21944951

Physical activity promotion for people with spinal cord injury: physiotherapists' beliefs and actions.

It is vital that people with spinal cord injury (SCI) lead a physically active lifestyle to promote long term health and well-being. Yet within rehabilitation and upon discharge into the community, people with SCI are largely inactive. Physiotherapists are well placed to promote a physically active lifestyle and are valued and trusted messengers of physical activity (PA) by people with SCI. Therefore this study aimed to explore the perceptions of physiotherapists in SCI rehabilitation on PA for people with SCI, and what is done to promote PA. Semi-structured interviews were completed with 18 neurological physiotherapists (2-22 years experience) from SCI centres in the United Kingdom and Ireland. Framed by interpretivism, an inductive thematic analysis was conducted. Three themes were identified: (1) perceived importance of PA; (2) inconsistent PA promotion efforts; and (3) concern regarding community PA. This article makes a significant contribution to the literature by identifying that although physiotherapists value PA, active promotion of PA remains largely absent from their practice. To enable physiotherapists to promote and prescribe PA as a structured and integral component of their practice, effective knowledge strategies need designing and implementing at the macro, meso, and micro levels of healthcare. Implications for Rehabilitation Physiotherapists are well placed to promote a physically active lifestyle and are perceived as valued and trusted messengers of physical activity (PA). The importance of PA for patients with spinal cord injury (SCI) is valued by physiotherapists yet PA promotion is largely absent from their practice. Physiotherapists lack specific education and training on PA and SCI and hold certain beliefs which restrict their promotion of PA. Knowledge translation across the macro, meso, and micro levels of healthcare are essential to facilitate effective PA promotion.

Today, many jobs are associated with the inactivity or sedentary lifestyle. Employees' health will be affected by their depriving of the benefits of physical activity (PA). Therefore, the present study was undertaken to determine the PA among employee women in Isfahan University of Medical Sciences based on the transtheoretical model. This is a cross-sectional study has been performed in Isfahan University of Medical Sciences employee women (2013). A convenience sample of 100 women was selected. Data were collected by validated and reliable questionnaire in three parts (demographics information, PA scale, and TTM constructs). Data were analyzed by SPSS SPSS (version 16.0; SPSS, IBM, Inc, Chicago, IL, USA) and descriptive and analytical statistics such as ANOVA and independent t-test were used. A two-tailed P < 0.05 was considered statistically significant. The mean of PA was 21.17 ± 27.30 min in a day. Weekly heavy, moderate, and light exercise mean was 0.72 ± 1.81, 0.89 ± 1.87 and 0.57 ± 1.57 days, respectively. In this study, 26% of women were in contemplation, 22% in contemplation, 20% in preparation, 13% in action, and 19% in the maintenance stage. Furthermore, there were significant differences between consciousness raising, dramatic relief, counter-conditioning, stimulus control, helping relationships, reinforcement management, and self-liberation with stages of change constructs. Because of a significant relationship between cognitive and behavioral processes and PA in this group, designing and implementing an educational program based on the transtheoretical model may be useful in promoting PA of a female employee.

Context: Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students. Objective: To assess PA participation and constraints to participation among athletic training students. Design: Cross-sectional study. Setting: Entry-level athletic training education programs (undergraduate and graduate) across the United States. Patients or Other Participants: Participants were 1125 entry-level athletic training students. Main Outcome Measure(s): Self-reported PA participation, including a calculated PA index based on a typical week. Leisure constraints and demographic data were also collected. Results: Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation. Conclusions: Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits. PMID:25689560

The main goals of this study were: (1) to examine the relationship between physical activity (PA) involvement and other leisure activities in a sample of Portuguese youth and (2) to analyze gender differences in PA and leisure-time activity structure. The sample comprised 1123 adolescents that were classified according to PA levels as active (n = 589) and nonactive (n = 534). A questionnaire assessing leisure-time activities was used. Girls were significantly more engaged in social leisure, dutiful, and individual artistic activities during leisure time, whereas boys were more involved in sports and computer and TV viewing activities. Significant associations between PA and social leisure were found in girls (r = .18, P < or = .001) and boys (r = .13, P < or = .01) after adjustment for age. The same was found between level of PA and sports engagement during leisure (girls: r = .56, P < or = .001; boys: r = .51, P < or = .001). In girls (r = .10, P < or = .05), but not in boys, a statistically significant association was found between PA and individual artistic activities. This study has certain implications for health-related PA promotion efforts. Our data give additional reinforcement to the importance of organized and nonorganized sports/PA during leisure time for overall levels of PA in adolescents.

This study assessed physical activity (PA) in community dwelling adults with Type 2 diabetes, using multiple instruments reflecting internationally normed PA and diabetes-specific self-care behaviors. Two hundred and fifty-three Black (44.8%) and White (55.2%) Americans [mean age = 57.93; 39.5% male] recruited at low-income clinic and community health settings. Participants completed validated PA self-report measures developed for international comparisons (International Physical Activity Questionnaire Short Form), characterization of diabetes self-care (Summary of Diabetes Self-Care Activities Measure; SDSCA) and exercise-related domains including provider recommendations and PA behaviors and barriers (Personal Diabetes Questionnaire; PDQ). Self-reported PA and PA correlates differed by instrument. BMI was negatively correlated with PA level assessed by the PDQ in both genders, and assessed with SDSCA activity items in females. PA levels were low, comparable to previous research with community and diabetes samples. Pain was the most frequently reported barrier; females reported more frequent PA barriers overall. When using self-report PA measures for PA evaluation of adults with diabetes in clinical settings, it is critical to consider population and setting in selecting appropriate tools. PA barriers may be an important consideration when interpreting PA levels and developing interventions. Recommendations for incorporating these measures in clinical and research settings are discussed.

2015-12-01

In its 20th year, the Physician Assistant Clinical Knowledge Rating and Assessment Tool (PACKRAT) is a student self-assessment that can assist physician assistant (PA) students and PA program faculty in identifying strengths and areas in need of improvement in the didactic and clinical phases of PA education. In this reflection, we provide an overview of the history of PACKRAT and outline some of its benefits for students and PA programs, as well as its generative role in assessment within PA studies. Taking a broader view of PACKRAT's impact on assessment for the PA profession, we outline the research on its benefits and its use to maximize student performance, as well as how it has promoted the development of additional assessment tools.

The Association between Short Periods of Everyday Life Activities and Affective States: A Replication Study Using Ambulatory Assessment

Bossmann, Thomas; Kanning, Martina; Koudela-Hamila, Susanne; Hey, Stefan; Ebner-Priemer, Ulrich

2013-01-01

Regularly conducted exercise programs effectively influence affective states. Studies suggest that this is also true for short bouts of physical activity (PA) of 10 min or less. Accordingly, everyday life activities of short duration might be used to regulate affective states. However, this association has rarely been studied in reference to unstructured activities in ongoing real-life situations. The current study examined the influence of various everyday life activities on three dimensions of mood (valence, calmness, energetic arousal) in a predominantly inactive sample. Ambulatory Assessment (AA) was used to investigate the association between actual PA and affective states during the course of 1 day. Seventy-seven students ages 19–30 participated in the study. PA was assessed with accelerometers, and affective state assessments were conducted hourly using an e-diary with a six-item mood scale that was specially designed for AA. Multilevel analyses indicated that the mood dimensions energetic arousal (p = 0.001) and valence (p = 0.005) were positively influenced by the intensity of the activity carried out in the 10-min prior to the assessment. As their activity increased, the participants’ positive feelings and energetic arousal increased. However, the students’ calmness was not affected by their activity levels. The findings highlight the importance of integrating short activity intervals of 10 min or less into everyday life routines to improve affective states. PMID:23596426

Integration of physical activity (PA) into the classroom may be an effective way of promoting the learning and academic achievement of children at elementary school. This paper describes the research design and methodology of an intervention study examining the effect of classroom-based PA on mathematical achievement, creativity, executive function, body mass index and aerobic fitness. The study was designed as a school-based cluster-randomized controlled trial targeting schoolchildren in 1st grade, and was carried out between August 2012 and June 2013. Eligible schools in two municipalities in the Region of Southern Denmark were invited to participate in the study. After stratification by municipality, twelve schools were randomized to either an intervention group or a control group, comprising a total of 505 children with mean age 7.2 ± 0.3 years. The intervention was a 9-month classroom-based PA program that involved integration of PA into the math lessons delivered by the schools' math teachers. The primary study outcome was change in math achievement, measured by a 45-minute standardized math test. Secondary outcomes were change in executive function (using a modified Eriksen flanker task and the Behavior Rating Inventory of Executive Function (BRIEF) questionnaire filled out by the parents), creativity (using the Torrance Tests of Creative Thinking, TTCT), aerobic fitness (by the Andersen intermittent shuttle-run test) and body mass index. PA during math lessons and total PA (including time spent outside school) were assessed using accelerometry. Math teachers used Short Message Service (SMS)-tracking to report on compliance with the PA intervention and on their motivation for implementing PA in math lessons. Parents used SMS-tracking to register their children's PA behavior in leisure time. The results of this randomized controlled trial are expected to provide schools and policy-makers with significant new insights into the potential of classroom-based PA to improve cognition and academic achievement in children.

Labor-intensive multistep biological tasks, such as the construction and cloning of DNA molecules, are prime candidates for laboratory automation. Flexible and biology-friendly operation of robotic equipment is key to its successful integration in biological laboratories, and the efforts required to operate a robot must be much smaller than the alternative manual lab work. To achieve these goals, a simple high-level biology-friendly robot programming language is needed. We have developed and experimentally validated such a language: Programming a Robot (PaR-PaR). The syntax and compiler for the language are based on computer science principles and a deep understanding of biological workflows. PaR-PaRmore » allows researchers to use liquid-handling robots effectively, enabling experiments that would not have been considered previously.

Physical inactivity is a leading cause of mortality worldwide. Many patterns of physical activity involvement are established early in life. To date, the role of easily identifiable early-life individual predictors of PA, such as childhood temperament, remains relatively unexplored. Here, we tested whether childhood temperamental activity level, high intensity pleasure, low intensity pleasure, and surgency predicted engagement in physical activity (PA) patterns 11 years later in adolescence. Data came from a longitudinal community study (N = 206 participants, 53% females, 70% Caucasian). Parents reported their children's temperamental characteristics using the Child Behavior Questionnaire (CBQ) when children were 4 & 5 years old. Approximately 11 years later, adolescents completed self-reports of PA using the Godin Leisure Time Exercise Questionnaire and the Youth Risk Behavior Survey. Ordered logistic regression, ordinary least squares linear regression, and Zero-inflated Poisson regression models were used to predict adolescent PA from childhood temperament. Race, socioeconomic status, and adolescent body mass index were used as covariates. Males with greater childhood temperamental activity level engaged in greater adolescent PA volume (B = .42, SE = .13) and a 1 SD difference in childhood temperamental activity level predicted 29.7% more strenuous adolescent PA per week. Males' high intensity pleasure predicted higher adolescent PA volume (B = .28, SE = .12). Males' surgency positively predicted more frequent PA activity (B = .47, SE = .23, OR = 1.61, 95% CI: 1.02, 2.54) and PA volume (B = .31, SE = .12). No predictions from females' childhood temperament to later PA engagement were identified. Childhood temperament may influence the formation of later PA habits, particularly in males. Boys with high temperamental activity level, high intensity pleasure, and surgency may directly seek out pastimes that involve PA. Indirectly, temperament may also influence caregivers' perceptions of optimal activity choices for children. Understanding how temperament influences the development of PA patterns has the potential to inform efforts aimed at promoting long-term PA engagement and physical health.

A 2014 meta-analysis found that by graduation, 16.6% of medical students had reported abuse, harassment, or discrimination and that this hostile environment caused an increase in depression and anxiety. The purpose of this research study was to increase the understanding of discrimination and psychological/physical abuse in physician assistant (PA) education programs and the potential impact on student attrition. Information was collected using an online, anonymous survey that asked about witnessed or experienced discrimination and psychological or physical abuse during the didactic and clinical years of training in PA programs in the United States. The survey received 1159 respondents, which represents 6.1% of total PA student enrollment. Up to 30% of respondents had witnessed or experienced discrimination, and up to 2.3% had experienced psychological abuse while in PA school. The majority of witnessed or experienced discrimination during PA education was not reported (<2%). Reports were not made because students feared retribution or they simply did not know who to report to, particularly if the incident involved faculty. Reducing the prevalence of discrimination in PA education requires recognition of this issue and targeted efforts to ensure that the infrastructure of every program is inclusive and values diversity of all kinds. The authors advocate that PA programs discuss their current institutional reporting structure; develop a universal curriculum on workplace violence, discrimination, and harassment; and develop value statements that explicitly identify diversity and equity as a core value as an important first step to improving the overall "climate" and culture of the program.

Despite considerable research and programmatic efforts to alleviate racial/ethnic disparities in physical activity (PA), disparities in PA among older minorities and major racial ethnic groups persist. This study explored perceptions of PA among regularly active (RA) and insufficiently active (IA) older African American women (AAW) and the factors that influence (positively and negatively) their physical participation in their socio-cultural environment. A total of 20 AAW aged 60 to 80 years participated in a cross-sectional mixed-methods study (i.e., qualitative and quantitative) employing participatory research approaches (i.e., photoelicitation) along with an objective assessment of PA. Nine women were considered RA and 11 IA according to current PA recommendations. RA and IA women held two major beliefs about the nature of PA (i.e., PA as a broadly defined construct that goes beyond traditional exercise routines; and PA and exercise are synonymous and can be used interchangeably) and had a good understanding of its benefits. Participants in both groups did not know about the importance of PA intensity for health benefits. Barriers and facilitator of PA were found to be similar among RA and IA participants. Special attention should be paid to providing access to no or low cost opportunities for PA participation in safe environments.

The aim was to estimate the prevalence of metabolic syndrome (MetS) criteria, elevated C-reactive protein (CRP), and physical activity (PA) as well as the odds of MetS criteria in those active versus inactive utilizing a representative sample of U.S. adolescents. The study sample (n = 676) included male and female adolescent (12-17 years) participants in the 2007-2010 National Health and Nutrition Examination Survey. The criteria analyzed were based on a modified definition of MetS using the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. Current adult cut points were used to determine elevated CRP. Activity was estimated using reported days per week and minutes per day of moderate/vigorous PA. The MetS criteria with the highest and lowest overall prevalence estimates were elevated fasting glucose and elevated blood pressure (20.7% [95% confidence interval, 17.02-24.38] and 5.7% [95% confidence interval, 3.70-7.70], respectively). The prevalence of elevated CRP was 7.1% (6.3% and 7.8% in males and females, respectively; p = .42). The prevalence of insufficient PA was 75.0%. Odds of low high-density lipoprotein cholesterol were significantly lower in active adolescents when compared with inactive adolescents (odds ratio = .39, p < .05). In a representative sample of U.S. adolescents, elevated fasting glucose is the most prevalent MetS criterion. One out of five U.S. adolescents has elevated fasting glucose, and three out four do not meet the daily federal PA recommendations. Adolescents meeting the federal PA recommendation demonstrate approximately 60% lower odds of having low high-density lipoprotein cholesterol.

Importance Whether sustained physical activity prevents cardiovascular disease (CVD) events in older adults is uncertain. Objective To test the hypothesis that cardiovascular morbidity and mortality was reduced in participants in a long-term physical activity program. Design, Setting, Participants The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicenter, randomized trial. Participants were recruited at 8 centers in the United States. We randomized 1635 sedentary men and women aged 70 to 89 years with Short Physical Performance Battery (SPPB) score of 9 or below, but able to walk 400 m. Interventions The PA intervention was a structured moderate intensity program, predominantly walking two times per week on site for 2.6 years on average. The SA intervention consisted of weekly health education sessions for six months, then monthly. Main Outcome Total CVD events, including fatal and non-fatal myocardial infarction (MI), angina, stroke, transient ischemic attack, and peripheral artery disease, were adjudicated by committee and silent MI was assessed by serial electrocardiograms. A limited outcome of MI, stroke, and CVD death was also studied. Outcome assessors and adjudicators were blinded to intervention assignment. Results New CVD events occurred in 14.8% (n=121/818) of PA and 13.8% (113/817) of SA participants (HR=1.10, 95%CI: 0.85 to 1.42). For the more focused combined outcome of MI, stroke or cardiovascular death, rates were 4.6% in PA and 4.5% in the SA group (HR = 1.05 (95%CI: 0.67 to 1.66). Among frailer participants with a SPPB <8, total CVD rates were 14.2% in PA vs 17.7% in SA with HR = 0.76 (95%CI: 0.52 to 1.10), compared with 15.3% vs. 10.5% with HR = 1.59 (95%CI: 1.09 to 2.30) among those with SPPB of 8 or 9 (p for interaction =0.006). With the limited endpoint, the interaction was not significant (p=0.59), with HR = 0.94 (95% CI: 0.50–1.75) for SPPB < 8 and HR = 1.20 (95% CI, 0.62–2.34) for SBBP of 8 or 9). Conclusions and Relevance Among participants in the LIFE Study, an aerobically-based, moderately intensive PA program did not reduce cardiovascular events in spite of the intervention’s previously documented ability to prevent mobility disability.

To assess the effect of a physical activity (PA) intervention on brain and behavioral indices of executive control in preadolescent children. Two hundred twenty-one children (7-9 years) were randomly assigned to a 9-month afterschool PA program or a wait-list control. In addition to changes in fitness (maximal oxygen consumption), electrical activity in the brain (P3-ERP) and behavioral measures (accuracy, reaction time) of executive control were collected by using tasks that modulated attentional inhibition and cognitive flexibility. Fitness improved more among intervention participants from pretest to posttest compared with the wait-list control (1.3 mL/kg per minute, 95% confidence interval [CI]: 0.3 to 2.4; d = 0.34 for group difference in pre-to-post change score). Intervention participants exhibited greater improvements from pretest to posttest in inhibition (3.2%, 95% CI: 0.0 to 6.5; d = 0.27) and cognitive flexibility (4.8%, 95% CI: 1.1 to 8.4; d = 0.35 for group difference in pre-to-post change score) compared with control. Only the intervention group increased attentional resources from pretest to posttest during tasks requiring increased inhibition (1.4 µV, 95% CI: 0.3 to 2.6; d = 0.34) and cognitive flexibility (1.5 µV, 95% CI: 0.6 to 2.5; d = 0.43). Finally, improvements in brain function on the inhibition task (r = 0.22) and performance on the flexibility task correlated with intervention attendance (r = 0.24). The intervention enhanced cognitive performance and brain function during tasks requiring greater executive control. These findings demonstrate a causal effect of a PA program on executive control, and provide support for PA for improving childhood cognition and brain health.

Reducing physical inactivity among the population is a challenge for many nations. Targeting leisure time physical activity (LTPA) may be useful in increasing overall physical activity as it is assumed it is associated with a higher degree of free choice and personal preference than physical activity at work and during travel. The study explored the prevalence of physical inactivity and focused on the overall level of energy expenditure and energy level spent during leisure time among those who were physically inactive and assessed the stages of change for LTPA among those who were physically inactive. A population-based survey was conducted in 2014 in Chiang Mai, Thailand using a stratified two-stage cluster sampling technique. The Global Physical Activity Questionnaire (GPAQ) was used to collect the data on physical activity. Sufficient levels of physical activity (PA) were defined as ≥150 min/week of moderate-intensity PA or ≥75 min/week of vigorous-intensity PA or ≥600 metabolic equivalent of task (MET)-minutes/week. Weighted analyses were used to estimate the prevalence of physical inactivity, the total energy expenditure and expenditure during LTPA as well as stages of change among the physically inactive population. A total of 1744 people (808 men and 936 women), aged 15 to 64 years, participated in the study. We estimated that a quarter (26%) of the population were physically inactive. Physical inactivity was more commonly found among women than men in most age groups. LTPA contributed a small proportion of overall PA. On average, physically inactive men spent 132.8 MET-minutes/week and inactive women spent 208.2 MET-minutes/week in overall PA which is well below the 600 MET-minutes/week recommend by the World Health Organization. Around 75% of physically inactive people had no intention of engaging in regular LTPA. About a quarter of the investigative population were physically inactive. Most physically inactive members of the population participate in low levels of LTPA, but the majority has no intention of increasing PA during leisure time. A large-scale health promotion program is needed, and it should focus on an approach for the pre-contemplated population.

This study aimed to assess the psychometric properties of a child-report, multidimensional measure of physical activity (PA) parenting, the Activity Support Scale for Multiple Groups (ACTS-MG), in African American and non-Hispanic white families. The ACTS-MG was administered to children aged 5 to 12 years. A three factor model of PA parenting (Modeling of PA, Logistic Support, and Restricting Access to Screen-based Activities) was tested separately for mother's and fathers' PA parenting. The proposed three-factor structure was supported in both racial groups for mothers' PA parenting and in the African American sample for fathers' PA parenting. Factorial invariance between racial groups was demonstrated for mother's PA parenting. Building on a previous study examining the ACTS-MG parent-report, this study supports the use of the ACTS-MG child-report for mothers' PA parenting. However, further research is required to investigate the measurement of fathers' PA parenting across racial groups.

Health-enhancing physical activities (PA) performed outdoors could markedly contribute to the adoption of a healthy lifestyle in adolescence. The differences between PA preferences and actual opportunities for these PA are an issue that has received frequent attention. To date, the extent to which these differences are reflected in adolescents meeting PA recommendations and their well-being has not been explored. In total, 10,086 respondents took part in an on-line research project regarding PA preferences. Of them, 2446 also completed the International Physical Activity Questionnaire (Long Form) and the World Health Organization (WHO) W-5 questionnaire to assess well-being. Finally, 1278 of these respondents were involved in objective PA monitoring using pedometers. The study aimed to explore the prevalence and trends regarding outdoor PA. Moreover, we assessed whether the agreement between preferred PA and PA actually undertaken was associated with higher odds for meeting PA recommendations and achieving a higher level of well-being. Of a selection of outdoor activities, Czech and Polish boys preferred cycling, swimming, and downhill skiing, while girls preferred swimming activities, skating, and cycling. The agreement between preferred and PA actually undertaken was associated with higher odds for meeting the weekly PA recommendations and higher levels of well-being both in boys and girls. Evaluation of outdoor PA preferences and taking these preferred activities into account when forming conditions for them was important in the efficient promotion of the physical and mental health of adolescents.

To assess physical activity (PA) behaviours of adults in rural Australia. Three cross-sectional surveys in the Greater Green Triangle area covering the south-east of South Australia (Limestone Coast), and south-west (Corangamite Shire) and north-west (Wimmera) of Victoria during 2004-2006. A total of 1546 persons, aged 25- 74 years, randomly selected from the electoral roll. Overall PA, leisure-time PA, occupational PA, active commuting and moderate-to-vigorous PA. Approximately 80% of participants, more women than men, engaged in 30 minutes or more of daily PA. Only 30% (95% CI 26.3, 33.0) of men and 21% (95% CI 18.3, 23.9) of women did moderate-to-vigorous PA for at least 20-30 minutes four or more times a week. In leisure time, most participants were moderately active; almost one-fifth were inactive and another fifth highly active. Two-thirds of men engaged in high-level occupational PA, compared with one-sixth of women. Only 30% of participants actively commuted to work. There was a tendency for a positive association between income level and leisure-time PA. One-fifth of adults in rural Australia were inactive. While there was a high prevalence of participants who engaged in daily PA, few did so at moderate-to-vigorous intensity to achieve health benefits. As occupational PA is difficult to change, improvements in levels of PA are more likely during leisure-time and for some people by engaging in commuting PA.

Structure and activity of the Pseudomonas aeruginosa hotdog-fold thioesterases PA5202 and PA2801.

The hotdog fold is one of the basic protein folds widely present in bacteria, archaea and eukaryotes. Many of these proteins exhibit thioesterase activity against fatty acyl-CoAs and play important roles in lipid metabolism, cellular signalling and degradation of xenobiotics. The genome of the opportunistic pathogen Pseudomonas aeruginosa contains over 20 genes encoding predicted hotdog-fold proteins, none of which have been experimentally characterized. We have found that two P. aeruginosa hotdog proteins display high thioesterase activity against 3-hydroxy-3-methylglutaryl-CoA and glutaryl-CoA (PA5202), and octanoyl-CoA (PA2801). Crystal structures of these proteins were solved (at 1.70 and 1.75 Å for PA5202 and PA2801 respectively) and revealed a hotdog fold with a potential catalytic carboxylate residue located on the long α-helix (Asp(57) in PA5202 and Glu(35) in PA2801). Alanine residue replacement mutagenesis of PA5202 identified four residues (Asn(42), Arg(43), Asp(57) and Thr(76)) that are critical for its activity and are located in the active site. A P. aeruginosa PA5202 deletion strain showed an increased secretion of the antimicrobial pigment pyocyanine and an increased expression of genes involved in pyocyanin biosynthesis, suggesting a functional link between PA5202 activity and pyocyanin production. Thus the P. aeruginosa hotdog thioesterases PA5202 and PA2801 have similar structures, but exhibit different substrate preferences and functions.

The heterotrimeric influenza virus polymerase, containing the PA, PB1 and PB2 proteins, catalyses viral RNA replication and transcription in the nucleus of infected cells. PB1 holds the polymerase active site and reportedly harbours endonuclease activity, whereas PB2 is responsible for cap binding. The PA amino terminus is understood to be the major functional part of the PA protein and has been implicated in several roles, including endonuclease and protease activities as well as viral RNA/complementary RNA promoter binding. Here we report the 2.2 angstrom (A) crystal structure of the N-terminal 197 residues of PA, termed PA(N), from an avian influenzamore » H5N1 virus. The PA(N) structure has an alpha/beta architecture and reveals a bound magnesium ion coordinated by a motif similar to the (P)DX(N)(D/E)XK motif characteristic of many endonucleases. Structural comparisons and mutagenesis analysis of the motif identified in PA(N) provide further evidence that PA(N) holds an endonuclease active site. Furthermore, functional analysis with in vivo ribonucleoprotein reconstitution and direct in vitro endonuclease assays strongly suggest that PA(N) holds the endonuclease active site and has critical roles in endonuclease activity of the influenza virus polymerase, rather than PB1. The high conservation of this endonuclease active site among influenza strains indicates that PA(N) is an important target for the design of new anti-influenza therapeutics.« less

In vitro regulation of pericellular proteolysis in prostatic tumor cells treated with bombesin.

Bombesin is a potent inducer of signal trasduction pathways involved in the proliferation and invasion of androgen-insensitive prostatic tumor cells. This study examines the bombesin-mediated modulation of pericellular proteolysis, monitoring cell capability to migrate and invade basement membranes, using a chemo-invasion assay and analyzing protease production. The results suggest that bombesin could modulate the invasive potential of prostatic cell lines regulating secretion and cell-surface uptake of uPA and MMP-9 activation. In fact, in PC3 and DU145 cells but not in LNCaP cells, urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) are induced by bombesin treatment. Bombesin also stimulates cell proliferation and this effect can be inhibited blocking uPA by antibodies and/or uPA inhibitor p-aminobenzamidine. Moreover, HMW-uPA induces cell proliferation in LNCaP cells, which do not produce uPA in the basal conditions, while PC3 and DU145 cell growth is supported by autocrine production of uPA. The increment of uPA activity on the external plasma membrane causes an increased pericellular plasmin activation. This effect is inhibited by antibodies against uPA and by p-aminobenzamidine. Similarly to EGF, bombesin stimulates secretion and activation of MMP-9 and TIMP-1 production. MMP-9 activation can be also obtained by HMW-uPA treatment, suggesting that plasma-membrane-bound uPA can start a proteolytic cascade involving MMP-9. Therefore, in in vitro assays, bombesin is able to modulate pericellular proteolysis and cell proliferation, differently distributing and activating proteolytic activities. This effect can be related to the "non-random" degradation of the extracellular matrix in which membrane uPA-uPAreceptor complexes could start bombesin-induced directional protein degradation during metastatic spread.

The Ciclovías comprise worldwide programs in which streets are closed to motor-vehicles and open to individuals for leisure activities. Currently, 93% of the regular programs are in Latin American countries (LAC). The aims of this study were to describe the characteristics of regular Ciclovías in 7 LAC and to analyze the factors that influence the sustainability and scaling-up of five case studies. We conducted a survey of 67 Ciclovías in 2014-2015. In addition, we conducted semi-structured interviews with current and former program coordinators and reviewed policy documents from Ciclovías in 5 LAC. The greatest expansion of Ciclovías has occurred since 2000. The number of participants per event ranged from 40 to 1,500,000 (mean 41,399±193,330; median 1600), and the length ranged from 1 to 113.6km (mean 9.1±16.4; median 3). Ciclovía routes connect low-middle and high income neighborhoods (89.3%), and include the participation of minority populations (61.2%). The main complementary activity offered was physical activity (PA) classes (94.0%), and 80.0% of the programs included strategies to promote biking. All five case studies met definitions for sustainability and scaling-up. All programs shared some level of government support, alliances, community appropriation, champions, compatibility with the mission of the host organization, organizational capacity, flexibility, perceived benefits, and funding stability. However, they differed in operational conditions, political favorability, sources of funding, and number of alliances. The Ciclovías of LAC showed heterogeneity within their design and sustainability factors. Both their heterogeneity and flexibility to adjust to changes make them promising examples of socially inclusive programs to promote PA. Copyright © 2016 Elsevier Inc. All rights reserved.

Previous research suggests the neighborhood environment may be an important influence on children's physical activity (PA) behaviors; however, findings are inconsistent. The purpose of this study was to further understand the relationship between perceptions of the neighborhood environment and children's afterschool moderate-to-vigorous PA. Utilizing a structural equation modeling technique, we tested a conceptual model linking parent and child perceptions of the neighborhood environment, parent support for PA, and child outdoor PA with children's afterschool moderate-to vigorous PA. We found that child perception of the neighborhood environment and outdoor PA were positively associated with afterschool moderate-to-vigorous PA. In addition, parent support for PA positively influenced children's outdoor PA. The neighborhood environment and outdoor activity appear to play an influential role on children's afterschool PA behaviors.

Whether sustained physical activity prevents cardiovascular disease (CVD) events in older adults is uncertain. To test the hypothesis that cardiovascular morbidity and mortality would be reduced in participants in a long-term physical activity program. The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicenter, randomized trial. Participants were recruited at 8 centers in the United States. We randomized 1635 sedentary men and women aged 70 to 89 years with a Short Physical Performance Battery (SPPB) score of 9 or less but able to walk 400 m. The physcial activity (PA) intervention was a structured moderate-intensity program, predominantly walking 2 times per week on site for 2.6 years on average. The successful aging intervention consisted of weekly health education sessions for 6 months, then monthly. Total CVD events, including fatal and nonfatal myocardial infarction, angina, stroke, transient ischemic attack, and peripheral artery disease, were adjudicated by committee, and silent myocardial infarction was assessed by serial electrocardiograms. A limited outcome of myocardial infarction, stroke, and CVD death was also studied. Outcome assessors and adjudicators were blinded to intervention assignment. The 1635 LIFE study participants were predominantly women (67%), with a mean (SD) age of 78.7 (5.2) years; 20% were African-American, 6% were Hispanic or other race or ethnic group, and 74% were non-Latino white. New CVD events occurred in 121 of 818 PA participants (14.8%) and 113 of 817 successful aging participants (13.8%) (HR, 1.10; 95% CI, 0.85-1.42). For the more focused combined outcome of myocardial infarction, stroke, or cardiovascular death, rates were 4.6% in PA and 4.5% in the successful aging group (HR, 1.05; 95% CI, 0.67-1.66). Among frailer participants with an SPPB score less than 8, total CVD rates were 14.2% in PA vs 17.7% in successful aging (HR, 0.76; 95% CI, 0.52-1.10), compared with 15.3% vs 10.5% among those with an SPPB score of 8 or 9 (HR, 1.59; 95% CI, 1.09-2.30) (P for interaction = .006). With the limited end point, the interaction was not significant (P = .59), with an HR of 0.94 (95% CI, 0.50-1.75) for an SPPB score less than 8 and an HR of 1.20 (95% CI, 0.62-2.34) for an SBBP score of 8 or 9. Among participants in the LIFE Study, an aerobically based, moderately intensive PA program was not associated with reduced cardiovascular events in spite of the intervention's previously documented ability to prevent mobility disability. clinicaltrials.gov Identifier: NCT00116194.

The number of physician assistant (PA) programs has increased exponentially across the past decade, and the demand for PAs will likely remain strong through 2025. Because of this rapid growth, both new and established PA programs face significant challenges in recruiting experienced educators. We describe the value of using PAs trained through the Interservice Physician Assistant Program (IPAP) as civilian PA educators. The literature on IPAP and its graduates proved too limited to conduct a formal systematic review. We searched the PubMed and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases for works speaking to the value that IPAP-trained PAs may bring to civilian PA training. Those findings were supplemented with informal conversations with IPAP-trained PAs currently employed in the military and those working in civilian PA education. Themes were identified supporting the potential value of IPAP-trained PAs in civilian training. Military PAs work within hierarchical organizations and may transition easily to academic settings. They leave military service not only as highly trained and proficient primary care providers but also as experienced educators. Military PAs must demonstrate professionalism across their entire military careers. They serve as leaders and work in teams, but they are also experienced in negotiating up chains of command. They are trained in and apply the latest innovations in health care delivery and have provided care with a degree of autonomy uncommon in civilian PA practice. The PAs trained through IPAP leave the service with skills and experiences valuable to civilian PA training. Employing these PAs in civilian education honors their service contributions while addressing emerging PA educator workforce demands.

Community trail development is an emerging strategy to increase physical activity (PA) among community residents. The purpose of this study was to assess awareness and use of trails and compare perceptions to objective data. A telephone survey was administered to a stratified sample of adults (N = 1,112) in a southeastern county in the United States. Respondents' home addresses and the locations of trails were entered into a GIS database. A kappa statistic was used to measure agreement between awareness and presence of trails. Differences in reported trail use patterns by sex, race, education, and PA levels were evaluated. There was no agreement between the awareness and presence of trails (kappa = 0.07). Fifty-six percent of the respondents reported having trails; however, only 33% reported using the trails. Of the trail users, 42% reported being regularly active in moderate-to-vigorous PA (30+ min/day for 5+ days/week), and 51% reported being less active (P < 0.003). Among walkers (> or =30 min/day for > or =5 days/week), 49% of regular walkers and 35% of irregular walkers (< walkers) reported using the trails (P < 0.04). Awareness of existing trails in this community and levels of use were low. Marketing programs should promote awareness and use of trails among older adults and irregularly active adults.

Primary care practitioners can play a significant role in helping patients adopt healthy behaviors such as physical activity (PA). The aim of this qualitative study was to assess family physicians' understanding and perception of the personal and environmental factors influencing PA, especially walking, and factors affecting their counseling of obese patients about environmental motivators and barriers to PA. We conducted five focus groups with 35 family physicians and 14 family medicine residents in four clinics and a residency program affiliated with CenTexNet, a primary care practice-based research network in central Texas. Data were transcribed and analyzed using thematic content analysis. Physicians were aware of the PA guidelines, but not many actually brought up PA during their counseling of patients. Physicians agreed that neighborhood environments are important for walking and reported that their patients often brought up environmental barriers. Physicians recommended walking as an ideal type of PA for obese patients and sidewalks, parks, and trails/tracks with smooth and soft surfaces as ideal places to engage in walking. However, they rarely talked about these factors with their patients due to a perceived ineffectiveness in counseling, an inability to address environmental factors, and time constraints in the medical encounter. While physicians believe neighborhood environments often present many barriers to PA, they still believe that environmental factors are secondary to personal motivation in promoting PA among obese patients. Physicians, if better informed of the growing evidence on the environment-PA links, may be able to facilitate patients' behavior change more effectively.

Understanding the modifiable factors that improve and maximize peak bone mass at an early age is necessary to design more effective intervention programs to prevent osteoporosis. To identify these modifiable factors, we analyzed the relationship of physical activity (PA), physical fitness, body composition, and dietary intake with bone stiffness index (SI), measured by quantitative ultrasonometry in young university students (18–21 years). Moderate-to-vigorous PA (MVPA) was the strongest predictor of SI (β = 0.184; p = 0.035). SI was most closely related with very vigorous PA in males (β = 0.288; p = 0.040) and with the number of steps/day in females (β = 0.319; p = 0.002). An association between thigh muscle and SI was consistent in both sexes (β = 0.328; p < 0.001). Additionally, extension maximal force was a bone SI predictor factor in females (β = 0.263; p = 0.016) independent of thigh muscle perimeter. Calcium intake was the only nutrition parameter that had a positive relationship with SI (R = 0.217; p = 0.022). However, it was not included as a predictor for SI in our regression models. This study identifies predictors of bone status in each sex and indicates that muscle and bone interrelate with PA and fitness in young adults. PMID:29320446

Being physically active is associated with lower risk of many noncommunicable diseases (NCDs). We analyzed physical activity (PA) data collected as part of Uganda's countrywide NCD risk factor survey conducted in 2014, to describe PA levels in Uganda. PA data were collected on the domains of work, travel and leisure. We calculated the percentage of participants meeting the World Health Organization (WHO) PA recommendations, and the types of intense-specific duration of PA. Prevalence ratios (PR) were used to identify factors associated with meeting WHO PA recommendations. Of the 3987 participants, 3758 (94.3%) met the WHO PA recommendations. Work-related PA of moderate intensity, and travel-related PA contributed most to participants' overall weekly duration of PA, each contributing 49.6% and 25.2% respectively. The median weekly duration of all moderate-intensity PA was 1470 minutes (interquartile range [IQR] = 540 to 2460). Weekly duration of all vigorous-intensity PA was low with a median of 0 minutes (IQR = 0 to 1080). The median daily sedentary time was 120 minutes (IQR = 60 to 240). Factors significantly associated with meeting WHO PA recommendations were body mass index and level of education. PA levels in Uganda are high, mostly achieved through travel and work-related activities of moderate intensity.

UDATE1: A computer program for the calculation of uranium-series isotopic ages

UDATE1 is a FORTRAN-77 program with an interface for an Apple Macintosh computer that calculates isotope activities from measured count rates to date geologic materials by uranium-series disequilibria. Dates on pure samples can be determined directly by the accumulation of 230Th from 234U and of 231Pa from 235U. Dates for samples contaminated by clays containing abundant natural thorium can be corrected by the program using various mixing models. Input to the program and file management are made simple and user friendly by a series of Macintosh modal dialog boxes. ?? 1991.

Physical activity (PA) is considered to have a beneficial influence on executive functioning, including decision-making. Enhanced decision-making after bariatric surgery may strengthen patients' ability to delay gratification, helping to establish appropriate eating behavior. The objectives of this study were to (1) compare a preoperative group with a postoperative group with regard to daily PA, decision-making, and eating disturbances; and (2) investigate the relationship between these variables. The study included 71 bariatric surgery candidates (78 % women, BMI [kg/m 2 ] M = 46.9, SD = 6.0) and 73 postoperative patients (78 % women, BMI M = 32.0, SD = 4.1; 89 % Roux-en-Y gastric bypass, 11 % sleeve gastrectomy; months postoperative M = 8.2, SD = 3.5; total weight loss [%] M = 33.2, SD = 8.9) who completed SenseWear Pro 2 activity monitoring. Decision-making was assessed using a computerized version of the Iowa Gambling Task and eating disorder psychopathology using the Eating Disorder Examination-Questionnaire. The number of patients who were classified as physically inactive was similarly high in the pre- and postoperative groups. No group differences emerged with regard to decision-making, but the postoperative group exhibited less eating disturbances than the preoperative group. No significant associations were found between PA, decision-making, and eating behavior. Patients after bariatric surgery were not more physically active than bariatric surgery candidates, which should be considered in care programs. Additionally, future research is needed to explore the possible link between PA, patients' decision-making abilities, and eating disturbances concerning dose-response questions.
