Park-Like Campus Settings and Physical Activity

Abstract

Objective: Similar to parks, college campuses may promote physical activity. The purpose of this study was to compare the physical activity of adults at urban campuses and parks. Participants: Participants were individuals observed on campuses and parks in April 2011. Methods: The System for Observing Play and Recreation in Communities was used to assess physical activity at 3 campuses and parks, 3 times/day, for 4 days. Results: Greater proportions of individuals (parks, campuses) were observed in vigorous (28.7%, 11.9%) and sedentary (25%, 18.3%) activities at parks than campuses and a greater proportion observed in walking (69.8%, 46.3%) intensity on campuses than parks. More men than women were observed at both parks and campuses, and paths and sport courts were most frequently used for physical activity. Conclusions: Physical activity intensities differ across college campuses and parks that provided similar physical activity amenities. Efforts should focus on increasing awareness of outdoor campus amenities that promote physical activity and understanding the outdoor amenities that of promote physical activity of women.     

Is “Walkability” A Useful Concept for Gerontology?

The study tested two hypotheses: that in a walkable neighborhood, residents will exercise more, eat healthier, and suffer from less obesity and that relation between environment and health outcomes will be stronger for the elderly. Health was measured by physical activity, the number of portions of fruits and vegetables eaten daily, and body mass index. Walkability was measured by three distinct environmental factors—distress, amenities, and residential. The three health outcomes were related to the three environmental factors. Age was not a significant predictor of health outcomes. Although the environment does contribute to health outcomes, the ways that contribution is expressed and its relation to age is complex.     

Best practices for physical activity programs and behavior counseling in older adult populations

Physical activity offers one of the greatest opportunities for people to extend years of active independent life and reduce functional limitations. The purpose of this paper is to identify key practices for promoting physical activity in older adults, with a focus on older adults with chronic disease or low fitness and those with low levels of physical activity. Key practices identified in promotion activity in older adults include: (1) a multidimensional activity program that includes endurance, strength, balance, and flexibility training is optimal for health and functional benefits; (2) principles of behavior change, including social support, self-efficacy, active choices, health contracts, assurances of safety, and positive reinforcement, enhance adherence; (3) management of risk by beginning at low intensity but gradually increasing to moderate physical activity which has a better risk/benefit ratio should be the goal for older adults; (4) an emergency procedure plan is prudent for community-based programs; and (5) monitoring aerobic intensity is important for progression and for motivation. Selected content reviews of physical activity programming from major organizations and institutions are provided. Regular participation in physical activity is one of the most effective ways for older adults, including those with disabilities, to help prevent chronic disease, promote independence, and increase quality of life in old age.Publication Note All National Blueprint Publications are in the public domain and can be freely reproduced without copyright.

Species richness in urban parks and its drivers: A review of empirical evidence

There is growing recognition of urban areas as hosts for innovative ways to conserve and promote biodiversity. Parks, as one specific type of urban green space, constitute particularly important biodiversity hotspots in the cityscape. We reviewed empirical findings on the species richness in urban parks across all species groups that have been studied. The aim was to assess and discuss the overall species richness of urban parks, its community attributes and drivers. Search and subsequent selection process resulted in 62 papers from 25 different countries. For all examined species groups, the findings consistently show that parks are among the most species rich types of urban green spaces, but also that exotics constitute large shares, especially of plant species. Key ecological theories like the gradient approach and the island habitat ecological theory, and fundamental ecological relationships such as the species-area relationship are valid despite the manipulated ‘nature’ of parks and the surrounding urban matrix. Most studies surveyed large number of parks and applied ‘multi-scale’ approaches in tests of confounding variables, providing methodological strength. While matrix effects are consistently found to affect species richness negatively, the diversity of habitats and microhabitat heterogeneity contained in urban parks appears as the most decisive factor for the overall species richness. However, a constraint of research to date is the limitation of individual studies to one or a few species groups, rarely bridging between flora and fauna. Adopting ‘multi-species group’ approaches in future research is needed to further advance the understanding of the overall biodiversity of urban parks, and its drivers.     

The impact of physical health and socioeconomic factors on sexual activity in middle-aged and elderly Taiwanese men

Sexual activity in older people has become a topic of growing interest. The aim of this study is to investigate the effect of physical health and socioeconomic factors on the sexual activity of middle-aged and elderly Taiwanese men. From August 2007 to April 2008, 744 men older than 40 years were enrolled from a free health screening in Kaohsiung, Taiwan. All participants received detailed physical examination and answered questionnaires that collected demographic and lifestyle information, and medical history as well as answered items from the International Prostate Symptoms Score and five-item version of the International Index of Erectile Function (IIEF-5). Overall, 100 (13.4%) participants reported to be sexually inactive in previous 6 months. Older age, lower education levels, loss of a partner, erectile dysfunction, and increased number of comorbidities were found to be independent predictors for sexual inactivity. In conclusion, most middle-aged and elderly Taiwanese men remain sexually active. In addition to erectile dysfunction and loss of a partner, lower education levels and increased number of comorbidities were found to be predictors for sexual inactivity. Further research would need to elucidate whether improvement of those factors could help to preserve sexual activity.     

Disability and physical activity in late life—research models and approaches

Prevention of disability in late life has become a major public health concern, a key area of ageing research, and also an important target for the development of effective interventions. The increase in life expectancy and the resulting growth of the elderly population are also thought to be driving up the number of elderly people with disabilities. Despite the message that regular moderate physical activity has substantial health benefits even in very old age, older people remain largely sedentary. The most popular theoretical model for researching the development of disability is the disablement process, which is widely used, in the gerontological literature. The main pathway according to this model leads from diseases and injuries to impairments, functional limitations, and disability. This approach has been challenged most particularly by models, which emphasize the social construction and determinants of disability. Numerous physical exercise interventions have aimed at preventing impairments, functional limitations and disability, and at promoting independent living in late life. A review of the results of these interventions shows that exercise can indeed be effective in preventing impairments and functional limitations, but the evidence regarding the prevention of disability and dependency is inconclusive. The inconsistency of the results is related to differences in research models and approaches, cultural and other differences between the populations studied, and variability in research designs and methods, including definitions of key variables. In the future, research-addressing disability in late life needs to focus on the dynamic interactions between individuals and their social, physical, and cultural environment. Furthermore, randomized trials that are larger and longer than most existing studies of physical activity need to be conducted. Additional evidence can also be obtained by well-conducted observational studies focusing on the prevention of progressive disability related to chronic conditions. One of the key areas of development is in improving the definition of both independent (physical activity and exercise) and outcome (functional limitations, disability) variables. A further challenge is presented by the investigation of dose–response relationships, including both beneficial and possible adverse effects of exercise.     

Physical activity in people age 80 years and older as a means of counteracting disability, balanced in relation to frailty

The aim of this study was to describe experiences of physical activity, perceived meaning, and the importance of and motives and barriers for participation in physical activity in people 80 years of age and older. A qualitative design with focus-group methodology was used. The sample consisted of 20 community-living people age 80-91 yr. Data analyses revealed 4 themes: physical activity as a part of everything else in life, joie de vivre, fear of disease and dependence, and perceptions of frailty. Our results suggest that physical activity was not seen as a separate activity but rather as a part of activities often rated as more important than the physical activity itself. Thus, when designing physical activity interventions for elderly people, health care providers should consider including time for social interaction and possibilities to be outdoors. Moreover, assessment of physical activity levels among elderly people should include the physical activity in everyday activities.     

Coalition for a Healthier Community: Lessons learned and implications for future work

The Coalition for a Healthier Community (CHC) initiative was implemented to improve the health and well-being of women and girls. Underpinning CHC is a gender-based focus that uses a network of community partners working collaboratively to generate relevant behavior change and improved health outcomes. Ten programs are trying to determine whether gender-focused system approaches are cost-effective ways to address health disparities in women and girls. Programs implemented through coalitions made up of academic institutions, public health departments, community-based organizations, and local, regional, and national organizations, are addressing health issues such as domestic violence, cardiovascular disease prevention, physical activity, and healthy eating. Although these programs are ongoing, they have made significant progress. Key factors contributing to their early success include a comprehensive needs assessment, robust coalitions, the diversity of populations targeted, programs based on findings of the needs assessments, evaluations taking into consideration the effect of gender, and strong academic–community partnerships. A noteworthy impact of these programs has been their ability to shape and impact public, social, and health policies at the state and local levels. However, there have been challenges associated with the implementation of such a complex program. Lessons learned are discussed in this paper.     

Physical activity assessment and health outcomes in old age: how valid are dose–response relationships in epidemiologic studies?

In this systematic review the validity of the dose–response relationships between physical activity (PA) and energy expenditure (EE) on defined health outcomes (cardio- and cerebrovascular morbidity and mortality, cancer) for the elderly is questioned. Medline, Cochrane, and EMBASE databases were reviewed for epidemiological longitudinal studies in populations aged 60+ for the years 1985–2007. Although most of the 18 identified studies generally demonstrated an inverse dose–response relationship between PA and EE level with morbidity and mortality, the range of dose–responses was remarkably broad. The nature of the dose–response relationship remained unclear. PA questionnaires - even those constructed for the elderly - do not cover the extremely diverse aspects of age-specific PA behavior and modes of muscular activity. Only non-age-specific tables had been used to estimate the EE in the elderly. Direct measurements of EE were limited. The results have implications for the interpretation of the dose–response relationships between PA and EE on defined health outcomes in old age.     

The impact of climate change and natural disasters on vulnerable populations: A systematic review of literature

ABSTRACT

Climate change is acknowledged as being a crucial determinant of public health. The United States is experiencing an increase in the frequency and intensity of natural disasters as a result of climate change activity, influencing the ways federal, state, and local governments are addressing the growing issue. Individuals who are vulnerable to the effects of extreme weather, namely the poor, the elderly/disabled, children, prisoners, and substance abusers have experienced heightened levels of mental, emotional, and bodily stress due to natural disaster exposure. Researchers from a variety of disciplines, public health, social science, and environmental studies, in particular, are examining how natural disasters are impacting mental and physical health functioning while noting the demographic factors leaving certain groups more susceptible to harm. A systematic literature review was conducted on the past 12 years of research that examined natural disaster-related experiences and psychological and physiological health outcomes on populations who are more vulnerable to adverse weather impacts. It was found that the mental and physical health of marginalized populations during and after a natural disaster were elevated and/or exacerbated by circumstances pertaining to the weather event and the lack of disaster-response actions. It was also found that fostering social capital is a way to combat stressors in disadvantaged communities. It is imperative that clinicians and policy makers confront the issue of climate change and natural disasters, developing relief efforts and preventative measures to secure the well-being of underserved groups who may not have many resources at their disposal.     

Perceptions of physical activity among elderly residents and professionals in assisted living facilities

Background

Physical activity is often described as being important for people of all ages, but what different people mean when they talk about physical activity is unclear.

Method

A phenomenographic method was used to analyze how 13 older people and 17 professionals answer the question, “If I say physical activity, what does the concept mean to you?” as part of semi-structured interviews conducted in four assisted living facilities in two different municipalities.

Results

We identified a number of different perceptions of physical activity, with the older people and professionals having different responses. Elderly and professionals alike, define physical activity as a requirement for life and as an opportunity to maintain the body although they define the concepts in different ways. Elderly define the concept as a way to create meaning and the professionals have the attitude that the concept means everyday activities.

Conclusion

The concept of physical activity may be defined in many different ways. This study has shown that elderly and professionals do not define physical activity in the same way. Therefore, professionals need to be aware of these differences when talking with elderly about individual needs in everyday life.

     

Health Care of American Indian Elderly: Determinants of the Perceived Difficulty Obtaining Access to Health Care

This study examines the perceived areas of difficulty in obtaining access to health care and the factors influencing that difficulty among elderly American Indians in a rural environment. One hundred thirty-seven elderly Indians in the Ponca and Pawnee tribes of Oklahoma were interviewed. Four major difficulties are reported: a long waiting period at Indian health centers, difficulty in making appointments to see physicians, language and cultural barriers to communication with the health care providers, and lack of available transportation. The long waiting period is the most serious problem, and lack of transportation is the least serious. The results of probit analysis show that physical health, automobile ownership, education, employment, and the presence of an informal caregiver are related to difficulty obtaining access to health care. Ways to minimize this difficulty are discussed.     

Psychological response to disasters: focus on adolescents

The effects of disasters may predispose many adolescents to psychological stress, which can interfere with their growth and development and disrupt their intrapsychic homeostasis. This may lead to negative long-term health outcomes and hamper normal development. Many nurses view traumatic events involving children, including adolescents, as the most frequent and stressful critical incidents. There is a need to address psychological emergency preparedness for mass disasters with the development of protocols and practice guidelines. Assessing and managing physical injuries may take priority in emergencies, but incorporating rapid, cost-effective mental health assessments for children and adolescents is essential.     

Health-related quality of life in older adults: Testing the double jeopardy hypothesis

The double jeopardy hypothesis posits that racial minority elderly suffer a double disadvantage to health due to the interactive effects of age and race. Empirical examinations have found mixed support for the proposition that the aging process heightens the health disadvantage for racial minorities compared to whites. Race-by-age differences are tested using a health-related quality of life measure that has been largely overlooked in previous double jeopardy analyses. The outcome, number of days in poor physical health during the past month, quantifies day-to-day physical well-being in a way not available to standard measures of morbidity and mortality. The data are from the 2003 California Health Interview Survey (CHIS) and were analyzed using negative binomial regression. Results show that the magnitude of differences in the number of physically unhealthy days for African Americans and Hispanics compared to their white counterparts is much larger in the elderly strata than that observed between younger groups. Additionally, social characteristics do not fully explain why racial differences in poor physical health days are greater at older ages. A life course perspective is proposed as one possible explanation for the double jeopardy finding. The results indicate a need to consider health-related quality of life outcomes when examining racial/ethnic health disparities among the elderly population. The appendix presents cross-validation of the 2003 CHIS results with the 2005 CHIS and the findings are replicated.     

Overview of the physiological changes and optimal diet in the golden age generation over 50

Basically, our lifespan is determined genetically. However, several other parameters such as the environment, lifestyle and diet have a high impact on living in the best of health. Many older persons suffer from various diseases, which often cannot be avoided; however, their development can be postponed and symptoms can be mitigated by a balanced diet, moderate physical activity as well as a healthy lifestyle. These diseases are, for example, sarcopenia (degenerative loss of muscle mass), osteoporosis (decomposition of bone structure), digestive restrictions, sensory impairment, water imbalance or a compromised immune system. Psychological modifications, obesity and loss of weight also commonly occur in older adults. To define an adequate diet for elderly between the ages 50 and 80 is difficult, even impossible, because the nutritional requirements differ between the dynamic quinquagenarian and the frailer eighty-year-old. However, several studies have shown that sufficient consumption of high-quality proteins, calcium, vitamin D, anti-oxidative food compounds, water as well as adapted energy values and nourishment with high-nutrient density in combination with physical activity especially help one to remain healthy to a great age. The cornerstone of healthy ageing is the maintenance of normal bodyweight in order to prevent the development of diseases such as osteoporosis, coronary heart disease or diabetes type 2. This publication will review the physiological changes that occur with advanced age and consequential nutritional recommendations for elderly persons.     

Editorial

This study aims to analyze the environmental elements of residential facilities for elderly people by using Antonovsky's salutogenic concept. The relationship between the environment and health is clearly identified. This information facilitates the presentation and development of residential facilities with healthy living conditions for elderly people in South Korea. The concept includes providing a residential environment that is safe from a variety of dangers by applying a barrier-free concept to address the physical changes of elderly people. It also provides an environment equipped with a continuous protection system that considers both the physical and sociopsychological aspects of this particular treatment environment.     

Effect of age and physical activity level on functional fitness in older adults

It is difficult to distinguish between the effects of age and physical activity level in the functional fitness level of older adults. The objective of this study was to determine the effects of age and physical activity level on some functional fitness parameters in community-dwelling older adults.Two hundred twenty-nine elderly (111 female; 118 male) aged between 65–87 years living in the Balçova municipality region were divided into two groups: the young elderly (65–69 years old) and the elderly (70 years old or over). The “seven-day physical activity recall questionnaire” was used to estimate physical activity level (PAL). The functional fitness evaluation included the body mass index (BMI), the lower body strength (LBS), the dynamic balance, and the aerobic endurance. The young elderly were significantly worse with regard to BMI and significantly better with regard to LBS, dynamic balance, and aerobic endurance than the elderly; in contrast, PAL did not affect any of the functional fitness parameters. The young elderly showed worse BMI than the elderly when the age groups were less active. The young elderly showed better LBS and dynamic balance than the elderly when the age groups were more active. The young elderly showed significantly better aerobic endurance than the elderly in both the less and more active age groups. This study confirms that age affects functional fitness, whereas PAL generally does not. However, being more active is advantageous for the young elderly with regard to BMI, LBS, and dynamic balance.     

Urbanization impacts on land snail community composition

Urbanization has tremendous impacts on most native species. This is especially true in land snails, which are surprisingly understudied organisms. Due to their low mobility and dispersal potential, land snails are valuable indicators of ecosystem disturbance. For this study, land snails were collected in 54 city parks along an urban gradient to understand impacts of urbanization on snail communities. Sampled parks include small extensively landscaped downtown parks, neighborhood and community parks, district parks, and large nature parks, each with variable vegetation, soil characteristics, disturbance regimes, and human activities. Sampling recovered 12,153 individual snails, representing 20 families, 43 genera, and 95 species. Seven new Tennessee state and 87 new county occurrences were recorded. Five non-native and one extra-limital non-native species were found, four of which are new Tennessee state records. Results show that urbanization greatly alters land snail community structure. Nature and district parks have significantly greater species richness, species diversity and species evenness than community, neighborhood, and downtown parks. Degradation of parks, distance from the park to the commercial city center and percent of coarse woody debris accounted for most of the variation between park types. Non-metric multidimensional scaling and pairwise Jaccard indices indicate that downtown snail communities are more similar whereas snail communities in nature parks are more distinct. This suggests that urbanization promotes homogenization among land snail communities. We also show that this homogenization is thus far driven mainly by synanthropic, broadly adapted native species rather than non-native snail species.     

Impact of recreational physical activity on bone mineral density in middle-aged men

Physical activity is known to exert beneficial effects on general health status of young, adult and elderly populations. Exercise (aside from genetic, hormonal, nutritional and pathological factors) also influences bone mineral density (BMD). Unfortunately, the association between physical exercise and BMD in adult population is controversial. Our aim was to assess relations between recreational physical activity and BMD in middle-aged men. We performed densitometry and hormonal measurements (total testosterone, free testosterone, dehydroepiandrosterone sulfate, estradiol) in a homogenous group of 38 subjects. Among them, we distinguished 22 who had not engaged in any physical activity, and 16 who had recreationally exercised for about 10 years. Both groups did not differ in regard to hormonal status. Similarly, densitometry did not reveal any statistically significant differences in BMD between both groups of men. Upon our observation, we can hypothesize that recreational physical activity does not affect bone mineral density in middle-aged men.
