Relevance of urban green space for physical activity and health-related quality of life in older adults

Emplacing reablement co-creating an outdoor recreation model in the rural Arctic

Reablement aims to enable older persons with functional decline to re-engage in meaningful activities. The benefits of engagement in outdoor activities are significant; however, reablement services primarily target function in indoor environments whereas descriptions of outdoor activities are sparse. The aim of this study was to create a model that integrates outdoor recreation into reablement. We therefore elaborated on an experienced based co-design methodology to create a model that integrates outdoor recreation for older persons in reablement in an Arctic, rural context in northern Norway. Stakeholders (N = 35), including reablement participants, participated in workshops, focus groups, and individual interviews. Based on the results, we co-created a person-centred model for outdoor recreation in reablement, including an assessment tool that can guide reablement staff in goal-setting practices. Accordingly, we argue that cherished locations holds significant meaning in the lives of older people and warrant recognition in reablement programmes. There is a need to evaluate the effects and feasibility of the model and the possibility for its implementation in other health care settings.

Comparison of static and dynamic exposures to air pollution, noise, and greenness among seniors living in compact-city environments

GPS technology and tracking study designs have gained popularity as a tool to go beyond the limitations of static exposure assessments based on the subject's residence. These dynamic exposure assessment methods offer high potential upside in terms of accuracy but also disadvantages in terms of cost, sample sizes, and types of data generated. Because of that, with our study we aim to understand in which cases researchers need to use GPS-based methods to guarantee the necessary accuracy in exposure assessment. With a sample of 113 seniors living in Barcelona (Spain) we compare their estimated daily exposures to air pollution (PM2.5, PM10, NO2), noise (dB), and greenness (NDVI) using static and dynamic exposure assessment techniques. Results indicate that significant differences between static and dynamic exposure assessments are only present in selected exposures, and would thus suggest that static assessments using the place of residence would provide accurate-enough values across a number of exposures in the case of seniors. Our models for Barcelona's seniors suggest that dynamic exposure would only be required in the case of exposure to smaller particulate matter (PM2.5) and exposure to noise levels. The study signals to the need to consider both the mobility patterns and the built environment context when deciding between static or dynamic measures of exposure assessment.

Successful aging and lifestyle comparison of Greeks living in Greece and abroad: the epidemiological Mediterranean Islands Study (MEDIS)

OBJECTIVES

Comparing lifestyle and successful aging between Greeks living in Greece (GG) and Greeks living abroad (GA) using a multidimensional model of successful aging including both biomedical and non-medical components.

METHODS

Anthropometric, clinical, psychological, socio-demographic, dietary and lifestyle parameters were assessed in a random sample of 252 GG and 252 GA. Successful aging was evaluated using the validated successful aging index (SAI range 0-10).

RESULTS

GA had better financial and educational status and scored higher in all social activity parameters (p's < 0.05). GA were more likely to be physically active (p < 0.001), had higher adherence to the Mediterranean diet (p < 0.001) and were less likely to be smoking (p = 0.008). Depression was more evident among GG compared to GA (p < 0.001). GA was aging significantly more successfully than GG (p < 0.001). Men irrespective of location were aging significantly more successfully than women (p < 0.05).

CONCLUSION

Place of residence and personal choices significantly affect the level of healthy aging among people with similar genetic backgrounds.

Analytical approaches to testing pathways linking greenspace to health: A scoping review of the empirical literature

BACKGROUND

Inadequate translation from theoretical to statistical models of the greenspace - health relationship may lead to incorrect conclusions about the importance of some pathways, which in turn may reduce the effectiveness of public health interventions involving urban greening. In this scoping review we aimed to: (1) summarize the general characteristics of approaches to intervening variable inference (mediation analysis) employed in epidemiological research in the field; (2) identify potential threats to the validity of findings; and (3) propose recommendations for planning, conducting, and reporting mediation analyses.

METHODS

We conducted a scoping review, searching PubMed, Scopus, and Web of Science for peer-reviewed epidemiological studies published by December 31, 2019. The list of potential studies was continuously updated through other sources until March 2020. Narrative presentation of the results was coupled with descriptive summary of study characteristics.

RESULTS

We found 106 studies, most of which were cross-sectional in design. Most studies only had a spatial measure of greenspace. Mental health/well-being was the most commonly studied outcome, and physical activity and air pollution were the most commonly tested intervening variables. Most studies only conducted single mediation analysis, even when multiple potentially intertwined mediators were measured. The analytical approaches used were causal steps, difference-of-coefficients, product-of-coefficients, counterfactual framework, and structural equation modelling (SEM). Bootstrapping was the most commonly used method to construct the 95% CI of the indirect effect. The product-of-coefficients method and SEM as used to investigate serial mediation components were more likely to yield findings of indirect effect. In some cases, the causal steps approach thwarted tests of indirect effect, even though both links in an indirect effect were supported. In most studies, sensitivity analyses and proper methodological discussion of the modelling approach were missing.

CONCLUSIONS

We found a persistent pattern of suboptimal conduct and reporting of mediation analysis in epidemiological studies investigating pathways linking greenspace to health; however, recent years have seen improvements in these respects. Better planning, conduct, and reporting of mediation analyses are warranted.

Positive HABITATS for physical activity: Examining use of parks and its contribution to physical activity levels in mid-to older-aged adults

Studies of parks and physical activity rarely identify the actual spaces participants use. Using data from the HABITAT project, a longitudinal cohort of mid-to older-aged (40-70 years) respondents (n = 11,036) living in Brisbane Australia, this study examined (1) the demographic characteristics of users and non-users of parks; (2) the park used and the characteristics and features of the most popular reported spaces; and (3) the level of physical activity undertaken in the reported parks and whether users had higher total physical activity levels than non-users. Park use was significantly higher (p < 0.01) among dog walkers, couples (over 40) living with children, and those living in least disadvantaged areas. Regular park use was significantly higher among users of larger-sized neighbourhood and district-catchment parks. Park users were 35% more likely to meet the physical activity guidelines (OR = 1.35, 95%CI 1.21-1.50, p < 0.001) compared with those who indicated they did nto regularly use a park. The size of the park used was positively associated with participation in physical activity. Users of larger-sized parks spent more time doing vigorous activity and engaged in more activity sessions than non-users. Future data obtained from large populations, including spatial examination of the actual parks used and their characteristics, are essential to facilitate planning for park provision, optimising the use of these spaces for recreation and physical activity by mid-to older-aged adults, and creating healthy communities.
