Do psychosocial factors moderate the association between objective neighborhood walkability and older adults' physical activity?

What Characteristics Modify the Relation of Neighborhood Walkability and Walking Behavior in Older Adults?

Background and Objectives

Neighborhood walkability can influence walking behaviors in older adults. However, its associations of walkability with walking may differ by demographic, socioeconomic, health, social, and residential characteristics due to factors such as increased vulnerability to environmental factors or increased resilience.

Research Design and Methods

In a sample of older adults (n = 493, median age = 82 [range 78-89], 56% female, 31% Black), a walkability index was derived from audits of Google Street View images of participants' immediate neighborhoods. Walking was self-reported in the past week. Effect modifiers by demographic (age, race, gender, marital status), socioeconomic (education, income), health (gait speed, falls, knee pain, depressive symptoms, cognitive status, perceived energy), social (driving status, social engagement), and residential/neighborhood (residence type, neighborhood socioeconomic status [SES], population density) characteristics were assessed by interaction terms in logistic regression models, adjusted for gender, race, gait speed, prior falls, high depressive symptoms, currently driving, and cognitive status. When effect modification was suggested (p for interaction <.1), adjusted analyses of walkability with walking stratified on the effect modifier were conducted.

Results

In this sample, 59% walked in the past week and greater walkability was associated with greater odds of walking (odds ratio [OR] = 1.16, 95% confidence interval [CI]: 1.01-1.34). This association (p for interaction range 0.002-0.07) was present for those who were not currently married (OR = 1.35, 95% CI: 1.17-1.56), who reported knee pain (OR = 1.40, 95% CI: 1.14-1.72) or high depressive symptoms (OR = 1.30, 95% CI: 1.06-1.60), or who had declining cognitive function (OR = 1.30, 95% CI: 1.09-1.55).

Discussion and Implications

High walkability may influence physical activity, particularly for those with vulnerabilities related to social, pain, and brain health characteristics. These results should inform neighborhood planning and targeted interventions for vulnerable older adults.

Barriers and Facilitators to Participation in Vigorous Lifestyle Physical Activity in Adults Aged 55-75 Years: A Scoping Review

Despite the well-known benefits of physical activity, less than half of adults aged 55-75 years participate in sufficient physical activity. Short bouts of vigorous intermittent lifestyle physical activity (VILPA) accumulated throughout the day can contribute toward the recommended volume of physical activity. A rich characterization of the barriers and facilitators to participation in VILPA is needed to develop targeted interventions. This scoping review aimed to identify barriers and facilitators to participation in different components of VILPA in adults aged 55-75 years, and to map barriers and facilitators to the Theoretical Domains Framework. Within the 18 eligible studies, the most prevalent barriers were related to a person's skills, environmental context, and social influences. Most facilitators were related to a person's goals, social influences, and environmental context. Interventions to promote VILPA should test the effectiveness of behavioral change measures related to the unique barriers and facilitators in this age group.

Walkability around the worksite and self-reported and accelerometer-measured physical activity among adults

This cross-sectional study investigated the relationship between GIS-measured worksite and home neighborhood walkability and several measures of physical activity (PA) in employed adults. Results revealed no significant correlation between worksite walkability and PA outcomes, contradicting the hypothesis of increased PA with improved walkability. However, for women and households without young children, a positive association was observed between worksite walkability and moderate-to-vigorous physical activity (MVPA). Additionally, home neighborhood walkability was linked to self-reported walking. The study highlights the need for further research into social and environmental factors at worksites impacting PA, and examination of PA behaviors in the context of increased remote work due to the COVID-19 pandemic.

Psychosocial and environmental factors related to physical activity in middle-aged and older adults

The social ecological model provides a comprehensive framework for understanding the multiple-level determinants of physical activity. This study explores the significant individual, social, and environmental variables and their interactions in relation to physical activity in middle-aged and older adults in Taiwan. A cross-sectional study design was implemented. Healthy middle-aged and older adults were recruited (n = 697) through face-to-face and online surveys. The data collected comprised self-efficacy, social support, neighbourhood environment, and demographic characteristics. Hierarchical regression was used for statistical analysis. Self-rated health (B = 74.74, p < .001; B = 101.45, p = .022) and self-efficacy (B = 17.93, p < .001; B = 14.95, p = .020) were the significant individual variables in both middle-aged and older adults. Neighbourhood environment (B = 6.90, p = .015) and the interaction between self-efficacy and neighbourhood environment (B = 1.56, p = .009) were significant in middle-aged adults. Self-efficacy was the most significant predictor for all participants, with the positive correlations of neighbourhood environment arising only for middle-aged adults with high self-efficacy. Policy making or project design should consider multilevel factors in order to facilitate their physical activity.

How different are objective operationalizations of walkability for older adults compared to the general population? A systematic review

Background

Walking is an essential activity for everyone and for older adults in particular, given that it is the most accessible form of physical activity and one of the healthiest transportation modes. Understanding how walkability (the potential of the environment to enable and/or encourage walking) has been objectively measured and analyzed for older adults is critical to create more inclusive, healthy, and sustainable environments and to promote healthy aging. Despite the numerous reviews on physical activity among older adults and its relationship with the built environment, the literature still lacks comparison reviews focusing specifically on objective operationalizations of walkability for older adults vs. the general population.

Methods

We conducted a systematic review of 146 empirical studies that measured walkability objectively in relation to walking-related outcomes. We compared studies focused on older adults (n = 24) and the general population (n = 122). Content analysis included the characteristics of the study design, walkability measures, spatial extent, and associations found between walkability and walking-related outcomes.

Results

In both groups of publications, the majority of studies were conducted in the US, Canada, and Europe, and largely in high-income countries. They were mostly published in health-related journals and used cross-sectional designs, operationalized walkability by using indexes, employed self-reported measures for walking-related outcomes, and found positive associations between walkability and walking outcomes. However, we observed some differences among studies focusing on older adults. Compared to studies focusing on the general population, a larger proportion of studies on older adults was conducted in the Middle East and Asia, and they used longitudinal designs, mixed methods to measure walking-related outcomes, variables related with land-use characteristics, safety from traffic and crime, and greenery, and a larger proportion found positive, as well as no associations between walkability and walking-related outcomes.

Conclusion

Although there is a promising increase in interest in older adults-focused walkability studies in the last decade, there is still a need for more studies focusing on different settings, using wider spatial extents, longitudinal designs, objective or mixed methods to collect outcome data, and specific variables and/or specially created indexes for older adults and for settings.

Community Environment and Attitudes Toward Retirement Among Chinese Older Adults: A Moderated Mediation Study

This study explored the effects of community environment on older adults' attitudes toward retirement based on a sample survey of 1,979 retired workers in a suburban district of Beijing, China. After controlling for demographic characteristics, it is found that older people's satisfaction with the community environment has a positive and direct effect on their retirement attitudes; community participation plays a mediating role in the relationship; and the mediating effect of community participation is moderated by a higher level of self-efficacy. Our results have practical significance for improving the quality of retirement life among older adults.

Psychosocial and Social Environmental Factors as Moderators in the Relation between the Objective Environment and Older Adults' Active Transport

In order to develop tailored interventions aiming to encourage active transport among older adults, it is important to gain insights into the modifiable moderators affecting active transport behavior considering the neighborhood in which one lives. Therefore, this study aimed to determine which objective physical environmental factors have an impact on the active transport behavior of Belgian older adults (≥65 years old) and which psychosocial and social environmental moderators influence those relationships. Data from 503 independent living older adults who participated the Belgian Environmental Physical Activity Study in Seniors were included. Multilevel negative binominal regression models (participants nested in neighborhoods) with log link function were fitted for the analyses. Our resulted indicated that older adults living in an environment with higher residential density, higher park density, lower public transport density, and more entropy index had higher active transport levels. Furthermore, different types of neighborhood in which older adults live can lead to different moderators that are decisive for increasing older adults’ active transport behavior. Therefore, based on our results some recommendations towards tailored interventions could be given to increase older adults’ active transport behavior depending on the environment in which one lives.

Planning Walkable Neighborhoods for “Aging in Place”: Lessons from Five Aging-Friendly Districts in Singapore

Today, “walkability” is considered a critical component of an aging-friendly neighborhood. This study examined the relationships between the neighborhood physical environment, walkability, and physical activity levels of older residents in Singapore. Five neighborhoods notable for their “aging in place” strategies were selected for a site survey. A questionnaire focusing on the evaluation of neighborhood walkability was administered to older adults in these neighborhoods. The questionnaire included three sections: neighborhood satisfaction, walkability, and the daily physical activity of older adults. The results indicated that adequate physical facilities and connectivity to the city were critical to older adults’ satisfaction with their neighborhoods. The mean walking time significantly dropped as the number of nearby facilities increased, and the number of facilities was negatively correlated with the daily activity levels of older adults. Thus, planners should attempt to calibrate the provision of neighborhood facilities to maintain the physical activity levels of older adults.

Social network moderators of the association between Ghanaian older adults' neighbourhood walkability and social activity

This study examined the moderating influences of active social networks (ASN), sedentary social networks (SSN) and ASN lost on the relationship between neighbourhood walkability and social activity in community-dwelling older adults aged 60 years or more in Accra, Ghana. A total of 863 individuals participated after G*Power 3.1 was utilized to calculate the minimum sample size. We analysed the data with Pearson's correlation test and hierarchical linear regression models. A sensitivity analysis was conducted to select the ultimate confounding variables. The study found a positive influence of neighbourhood walkability on social activity after the covariate adjustment (β = 0.18; t = 5.2; p = 0.000). The positive influence of neighbourhood walkability on social activity was significantly reduced by ASN lost and SSN. ASN did not have a significant moderating influence on the primary relationship. The study concludes that the positive influence of walkable neighbourhoods on social activity decreases as SSN and ASN lost increase.

A comprehensive bibliometrics of 'walkability' research landscape: visualization of the scientific progress and future prospects

This study quantitatively investigated the scientific progress of walkability research landscape and its future prospects using bibliometric indicators to highlight the research hotspots. The results accentuated multifaceted nature of walkability research landscape with a strong association towards public health disciplines. Keyword co-occurrence analysis emphasized that majority of the walkability studies centred on the interactions between walking and other three main factors such as built environment attributes, transportation and obesity. Based on the identified research hotspots, a brief state-of-the-art review of walkability studies was presented. Future prospects based on the unexplored research gaps within the hotspots were also discussed. High correlation (r = 0.99, p < 0.05) between annual publications and citation counts demonstrated the significance of walkability studies to the contemporary scientific community. Being one of the comprehensive studies to evaluate the historic trajectory of walkability research landscape, the findings were expected to accelerate a comprehensive understanding of the walkability research domain that will assist future research direction.

Associations between individual factors, environmental factors, and outdoor independence in older adults

The degree to which individuals can accomplish outdoor activity by themselves or require support is an important facet of successful aging. While prior research focuses on participation in outdoor activity, understanding of older adults' outdoor independence is limited. We adopt an ecological approach to examine the role of individual factors and environmental factors in explaining outdoor independence. Our sample comprised older adults aged 65 + living in a medium-sized city in Germany (N = 1070). The results show that being male, younger, and healthier was positively associated with outdoor independence, while living together was not. Further, outdoor independence decreased with higher levels of perceived environmental barriers. This negative association was moderated such that it was stronger for the less healthy and older participants. Based on our empirical findings, we offer insights for policy makers, urban planners, and community groups to design age-friendly communities and consequently facilitate outdoor independence among older adults.

Cognitive Functioning as a Moderator in the Relationship Between the Perceived Neighborhood Physical Environment and Physical Activity in Belgian Older Adults

Objective: To investigate whether the relationship of neighborhood environmental factors with physical activity (PA) is moderated by cognitive functioning in Belgian older adults. Methods: Seventy-one older adults completed validated questionnaires on PA and environmental perceptions, wore an accelerometer, and completed a computerized assessment of cognitive functioning. Moderated linear regression analyses were conducted in SPSS 24.0. Results: Overall cognitive functioning significantly moderated the associations of traffic safety and street connectivity with PA. Detailed analyses showed that these factors were only positively associated with PA in older adults with lower cognitive functioning. In addition, particularly, performance on tests assessing visuospatial and episodic memory moderated these associations. Discussion: Living in traffic-safe neighborhoods with short and many alternative routes might motivate older adults with lower cognitive functioning to be active. As such, the increase in PA might improve their cognitive abilities. This knowledge is crucial for health practitioners to develop effective PA promotion initiatives.

A systematic review of barriers and motivators to physical activity in elderly adults in Iran and worldwide

OBJECTIVES

This study was conducted to identify and characterize the barriers and motivations to physical activity (PA) for elderly adults in Iran and other countries.

METHODS

We searched 6 databases (PubMed, Embase, Scopus, Web of Science, Magiran, and the Scientific Information Database) from 2000 to the November 2017, using "aged 60 and over," "physical activity" or "exercise," and "motivator" and "barrier" as keywords. Two reviewers independently performed the search, screening, and quality assessment of the studies.

RESULTS

In total, 34 papers were finally included in the study. The most important barriers, based on the frequency of factors, included physical problems, having no companions, and physical barriers to walking. The motivators included improving one's physical condition, being social, and suitability of the physical environment.

CONCLUSIONS

Important motivators and barriers to PA were more closely related to intrapersonal factors than to the interpersonal and environmental domains. The barriers and motivators to PA in the elderly were not markedly different between Iran and other countries. Therefore, a general strategy could be designed to improve PA in the elderly.

Cognitive resources moderate the adverse impact of poor perceived neighborhood conditions on self-reported physical activity of older adults

Poor neighborhood conditions are associated with lower levels of physical activity for older adults but socio-ecological models posit that physical activity depends on both environmental and individual factors. Older adults' ability to overcome environmental barriers to physical activity may partially rely on cognitive resources. However, evidence on the moderating role of these cognitive resources in the associations between environmental barriers and physical activity is still lacking. We analyzed cross-national and longitudinal data on 28,393 adults aged 50 to 96 years as part of the SHARE. Lack of access to services and neighborhood nuisances were used as indicators of poor neighborhood conditions. Delayed recall and verbal fluency were used as indicators of cognitive resources. Confounder-adjusted generalized estimation equations were conducted to test associations between neighborhood conditions and self-reported moderate physical activity, as well as the moderating role of cognitive resources. Results showed that poor neighborhood conditions reduced the odds of engagement in physical activity. Cognitive resources robustly reduced the adverse influence of poor neighborhood conditions on physical activity. Participants with lower cognitive resource scores showed lower odds of engaging in physical activity when neighborhood conditions were poorer, whereas these conditions were not related to this engagement for participants with higher cognitive resource scores. These findings suggest that cognitive resources can temper the detrimental effect of poor neighborhood conditions on physical activity. Public policies should target both individual and environmental factors to tackle the current pandemic of physical inactivity more comprehensively.

Environmental Factors Associated with Older Adult’s Walking Behaviors: A Systematic Review of Quantitative Studies

The aim of this study is to systematically review the relationship between neighborhood environments and all types of walking behaviors among older adults. Seventy peer-reviewed journal articles which met the selection criteria were examined. Research designs were summarized by geographical location and the associations of environmental characteristics and walking were calculated. Interactions between moderators and environmental characteristics for all types of walking were also categorized. Results have shown that transport walking is the most supported by neighborhood environmental characteristics. The positively related environmental characteristics are walkability, urbanization, land use mix-diversity and accessibility, walking amenities, and bicycle lanes. Total walking was positively associated with walkability and urbanization. Recreational walking was associated with neighborhood employment/income level, nearness to public transport/bus stops, and social cohesion. The most commonly used moderators were age and gender, but inconsistent moderating effects between neighborhood environments and walking were also found. In densely populated environments such as Hong Kong, older adults walked mostly for both transport and recreation. In contrast, American older adults in low density areas walked less for transport and more for recreation. Findings support a strong relationship between neighborhood environments and older adults’ walking. Future research should focus on longitudinal studies and comparison studies by geographic location.

Age, sex and other correlates with active travel walking and cycling in England: Analysis of responses to the Active Lives Survey 2016/17

Active travel (walking or cycling for transport) can generate personal and environmental benefits. We determined the frequency of participation in walking or cycling active travel by age and sex, as well as used multivariate analysis to find correlations with many other factors using a large cross-sectional 2016/17 survey of people living in England. Walking and cycling active travel were explored separately. Most respondents reported no active travel, but at least 25% of people under age 45 met activity recommendations only from active travel. Otherwise, (unlike other types of physical activity) active travel declined consistently with increased age. Men reported much more cycling active travel than women, who were more likely to do any active travel walking and therefore more likely to meet activity guidelines from just active travel walking. Lower levels of disability, fewer children in household, and working full time increased active travel. Season was sometimes relevant. BMI, personal-effectiveness, deprivation and rurality had mixed relationships with types of active travel. Understanding differences in correlates for cycling vs. walking active travel could help tailor local promotion programmes for each. The analysis suggests that motivators and barriers for active travel greatly by age.

Relationships Between Neighbourhood Physical Environmental Attributes and Older Adults' Leisure-Time Physical Activity: A Systematic Review and Meta-Analysis

BACKGROUND

Activity-friendly neighbourhood physical environments with access to recreational facilities are hypothesised to facilitate leisure-time physical activity (LTPA) among older adults (≥ 65 years old). The aim of the current study was to systematically review and quantitatively summarise study findings on the relationships between physical environmental attributes and LTPA among older adults.

METHODS

An extensive search of literature, including grey literature, yielded 72 articles eligible for inclusion. The reported associations between seven categories of environmental attributes and six LTPA outcomes were extracted, weighted by sample size and study quality, and quantitatively summarised. Reported moderating effects of individual and environmental characteristics and neighbourhood definition were also examined.

RESULTS

We observed positive associations for walkability (p = 0.01), land-use mix-access (p = 0.02) and aesthetically pleasing scenery (p < 0.001) with leisure-time walking. For leisure-time walking within the neighbourhood, evidence was found for positive associations with land-use mix-access (p = 0.03) and access to public transit (p = 0.05), and a negative association with barriers to walking/cycling (p = 0.03). Evidence for positive relationships between overall LTPA and access to recreational facilities (p = 0.01) and parks/open space (p = 0.04) was found. Several environmental attribute-LTPA outcome combinations were insufficiently studied to draw conclusions. No consistent moderating effects were observed for individual and environmental characteristics and neighbourhood definition.

CONCLUSIONS

The observed significant relationships can be used to inform policy makers and planners on how to (re-)design neighbourhoods that promote LTPA among older adults. Many environmental attribute-LTPA outcome relationships have been studied insufficiently and several methodological issues remain to be addressed.

Individual, social, and physical environmental factors related to changes in walking and cycling for transport among older adults: A longitudinal study

To date, no longitudinal studies examined the change in walking and cycling for transport as distinct outcomes over time and investigated the predictors of those changes. Therefore, this present study examined the change in odds of engagement in walking and cycling for transport as distinct outcomes among Belgian older adults over a three-year follow-up period, and examined factors (i.e. socio-demographics, psychosocial, perceived social and physical environmental characteristics) related to these changes in engaging in walking and cycling for transport. Against our expectations, we found significantly higher odds of engaging in cycling for transport among older adults at follow-up compared to baseline and no significant differences in the odds of engaging in walking for transport. Interventions should assist older adults to increase their self-efficacy towards PA, their perceived benefits of PA, and their perception of land use mix diversity in their neighborhood in order to increase the engagement in walking/cycling for transport over time, or help to decrease their perceived barriers towards PA or their perception to have a lot of physical barriers to walk/cycle in their neighborhood. Future longitudinal studies with larger samples are warranted investigating interaction effects between different predictors at various levels to find out which factors can be further integrated into active transport interventions in older adults.

Neighborhood walkability and physical activity among older women: Tests of mediation by environmental perceptions and moderation by depressive symptoms

Features that enhance neighborhood walkability (higher population density, street connectivity and access to destinations) are associated with higher levels of physical activity among older adults. The perceived neighborhood environment appears to mediate associations between the objective built environment and physical activity. The role of depressed mood in these associations is poorly understood. We examined the degree to which depressive symptoms moderated indirect associations between the objective neighborhood environment and physical activity via the perceived neighborhood environment in older women. We analyzed data on 60,133 women (mean age = 73.1 ± 6.7 years) in the U.S. Nurses' Health Study cohort who completed the 2008 questionnaire. Self-reported measures included the Geriatric Depression Scale, perceived presence of recreational facilities, retail destinations, sidewalks, and crime, and participation in recreational physical activity and neighborhood walking. We created an objective walkability index by summing z-scores of intersection and facility counts within 1200-meter residential network buffers and census tract-level population density. We used multiple regression with bootstrap-generated 95% bias-corrected confidence intervals (BC CIs) to test for mediation and moderated mediation. Objective walkability was associated with 1.99 times greater odds of neighborhood walking (95% BC CI = 1.92, 2.06) and 1.38 times greater odds of meeting physical activity recommendations (95% BC CI = 1.34, 1.43) via the perceived neighborhood environment. These indirect associations were weaker among women with higher depressive symptom scores. Positive associations between objective neighborhood walkability and physical activities such as walking among older women may be strengthened with a reduction in their depressive symptoms.

Understanding Physical Activity through Interactions Between the Built Environment and Social Cognition: A Systematic Review

BACKGROUND

Few people in most developed nations engage in regular physical activity (PA), despite its well-established health benefits. Socioecological models highlight the potential interaction of multiple factors from policy and the built environment to individual social cognition in explaining PA.

OBJECTIVE

The purpose of this review was to appraise this interaction tenet of the socioecological model between the built environment and social cognition to predict PA.

METHODS

Eligible studies had to have been published in peer-reviewed journals in the English language, and included any tests of interaction between social cognition and the built environment with PA. Literature searches, concluded in October 2017, used five common databases. Findings were grouped by type of PA outcomes (leisure, transportation, total PA and total moderate-vigorous PA [MVPA]), then grouped by the type of interactions between social cognitive and built environment constructs.

RESULTS

The initial search yielded 308 hits, which was reduced to 22 independent studies of primarily high- to medium-quality after screening for eligibility criteria. The interaction tenet of the socioecological model was not supported for overall MVPA and total PA. By contrast, while there was heterogeneity of findings for leisure-time PA, environmental accessibility/convenience interacted with intention, and environmental aesthetics interacted with affective judgments, to predict leisure-time PA. Interactions between the built environment and social cognition in PA for transport are limited, with current results failing to support an effect.

CONCLUSIONS

The results provide some support for interactive aspects of the built environment and social cognition in leisure-time PA, and thus highlight potential areas for integrated intervention of individual and environmental change.

An exploratory analysis of the interactions between social norms and the built environment on cycling for recreation and transport

Background

There is growing evidence of the public health benefits of promoting cycling. The ways that the built environment and perceived social norms independently influence cycling participation is well established. However, whether these factors interact to influence cycling participation has not been examined. Such research is important because understanding the effect of multiple socio-ecological factors and the interactions between them is needed to guide the development of interventions and strategies to increase cycling participation. Therefore, the aim of this study is to explore the interactive effects of the built environment and perceived social norms on transport and recreational cycling.

Methods

Data was collected using a self-administered online questionnaire from 228 office workers in Metropolitan Melbourne, Australia. Measures used in previous research were employed to assess self-reported transport and recreation cycling in the last week, perceptions of neighbourhood built environment, perceived social norms towards cycling, and objective land-use mix, residential density and street connectivity of the suburbs in which participants lived and work. Multiple binary logistic regression analyses were conducted to explore the interactive effects of the built environment and perceived social norms on transport and recreation cycling. All interactive effects were considered significant at p < 0.10.

Results

There was a significant interactive effect between the workplace built environment and perceived group norm on transport cycling (p = 0.06). There were no other significant interactive effects observed between components of the built environment and perceived social norms on transport or recreational cycling.

Conclusions

The interactive effect found in this study provides some evidence that the workplace built environment interacts with perceived group norms to influence cycling for transport. Positive perceptions of the workplace built environment, such as showers and secure bike racks, can somewhat compensate for the negative influence of when cycling is considered less of a norm among, family, friend or colleagues. However, the findings of this study did not support that the neighbourhood built environment and perceived social norms interact to influence cycling for recreation or transport. These findings contribute to the knowledge of how multiple factors may reciprocate to influence individual’s decision to cycle. More research into the interactive effects of socio-ecological factors is warranted.

Older Adults' Needs and Preferences for Open Space and Physical Activity in and Near Parks: A Systematic Review

Major gaps exist in the literature regarding the link between open space and physical activity promotion for older adults. This study conducted a systematic review on older adults, open space, and physical activity to identify their needs and preferences in and near parks. We identified 48 peer-reviewed journal articles. All articles focused on older adults but not necessarily exclusively. Most studies were descriptive and correlational. Findings suggest that older adults have specific open space and physical activity needs in and near parks that partly overlap with younger people. Framed by the biopsychosocial framework, open space and physical activity in and near parks can benefit older adults' physical health and psychologically well-being to stay socially engaged. Framed within the person-environment and life span perspectives, open space and physical activity in and near parks can facilitate an optimum fit between older adults and their environment as they continue to develop over time.

Independent Associations and Interactions of Perceived Neighborhood and Psychosocial Constructs on Adults' Physical Activity

BACKGROUND

Neighborhood and psychosocial variables are related to physical activity (PA), yet interactions between these factors in predicting PA are infrequently studied.

METHODS

This analysis examines the independent associations and interactions between self-reported neighborhood and psychosocial variables in relation to moderate to vigorous PA (MVPA) among adults from a US panel sample.

RESULTS

In adjusted models, neighborhood social capital was positively associated with meeting MVPA guidelines. Fewer barriers, greater self-efficacy, and greater autonomous motivation also corresponded with greater odds of meeting MVPA guidelines. An interaction between social capital and autonomous motivation showed that social capital was only associated with MVPA when autonomous motivation was high. Participants who reported both high autonomous motivation and high social capital were most likely to meet MVPA guidelines.

CONCLUSIONS

Neighborhood social capital, barriers, self-efficacy, and autonomous motivation may be important correlates in promoting adults' PA. Future directions include using objective neighborhood and PA data in similar analyses and investigating associations of neighborhood and psychosocial variables with multiple PA activities. Intervention research to promote PA should also examine whether effects of interventions targeting psychosocial constructs are moderated by features of an individual's neighborhood or whether perceived social capital can be addressed in interventions in conjunction with psychosocial variables.

Smoking and sedentary behavior changes from adolescence to emerging adulthood: A multilevel modeling perspective

The present research investigated a) the effects of psychological (e.g., depressive symptoms, delinquency) and neighborhood socioeconomic environmental factors (e.g., education, poverty, proportion of racial/ethnic minorities) on changes in smoking and sedentary behaviors from adolescence to emerging adulthood and b) whether there were any cross-level interactions based on socio-ecological models. A series of multilevel analyses (level-1: individual-level; level-2: neighborhood-level) were conducted with the National Longitudinal Study of Adolescent Health (Add Health) wave I (1995) and wave III (2001) data among about 10,000 US adolescents. Adolescents' delinquency (but not depressive symptoms) predicted emerging adults' progression to daily smokers. Adolescents living in neighborhoods with more Hispanics reported being less likely to initiate smoking and progress to daily smoking during emerging adulthood. Adolescents living in neighborhoods with lower education levels reported more sedentary behaviors during emerging adulthood. However, there were no cross-level interactions between individual-level psychological factors and neighborhood-level environmental factors. Supporting the notion of socio-ecological models, not only psychological factors but also neighborhood environments warrant research attention to explain changes in risky health behaviors from adolescence to emerging adulthood. Theory-based research with appropriate characteristics across multiple levels is required to better understand emerging adults' risky health behaviors.

Which psychological, social and physical environmental characteristics predict changes in physical activity and sedentary behaviors during early retirement? A longitudinal study

BACKGROUND

In the context of healthy ageing, it is necessary to identify opportunities to implement health interventions in order to develop an active lifestyle with sufficient physical activity and limited sedentary time in middle-aged and older adults. The transition to retirement is such an opportunity, as individuals tend to establish new routines at the start of retirement. Before health interventions can be developed, the psychological, social and physical environmental determinants of physical activity and sedentary behaviors during early retirement should be identified, ideally with longitudinal studies. The aim of this paper was first to examine whether psychological, social and physical environmental factors at the start of retirement predict longitudinal changes in physical activity and sedentary behaviors during the first years of retirement. Second, moderating effects of gender and educational levels were examined.

METHODS

This longitudinal study was conducted in Flanders, Belgium. In total, 180 recently retired (>1 month, <2 years at baseline) adults completed a postal questionnaire twice (in 2012-2013 and two years later in 2014-2015). The validated questionnaire assessed socio-demographic information, physical activity, sedentary behaviors, and psychological, social and physical environmental characteristics. Multiple moderated hierarchic regression analyses were conducted in SPSS 22.0.

RESULTS

Higher perceived residential density (p < 0.001) and lower aesthetics (p = 0.08) predicted an increase in active transportation (adjusted R² = 0.18). Higher baseline self-efficacy was associated with an increase in leisure-time physical activity (p = 0.001, adjusted R² = 0.13). A more positive perception of old age (p = 0.04) and perceiving less street connectivity (p = 0.001) were associated with an increase in screen time (adjusted R² = 0.06). Finally, higher baseline levels of modeling from friends (p = 0.06) and lower perceived land use mix access (p = 0.09) predicted an increase in car use (adjusted R² = 0.06). A few moderating effects, mainly of educational level, were found.

DISCUSSION

Walkability characteristics (perceived residential density) and self-efficacy at the start of retirement are the most important predictors of longitudinal changes in active transportation and leisure-time physical activity. Few moderating effects were found, so health interventions at the start of retirement focusing on self-efficacy and specific walkability characteristics could be effective to increase physical activity in recently retired adults. No firm conclusions can be drawn on the importance of the examined predictors to explain change in car use and screen time, possibly other factors like the home environment, or automatic processes and habit strength are more important to explain sedentary behaviors.

The moderating effect of psychosocial factors in the relation between neighborhood walkability and children's physical activity

Background

The study aimed to investigate if psychosocial factors moderate the association between objective walkability and different domains of children’s physical activity (PA). A second aim of the study was to investigate the direct associations between psychosocial factors and children’s PA. Based on previous literature, it was hypothesized that walkability would be more strongly related to PA among children with negative psychosocial profiles.

Methods

Data were collected between December 2011 and May 2013 as part of the Belgian Environmental Physical Activity Study in children (BEPAS-child). In total, data from 494 children and one of their parents were included in the study. Children wore an accelerometer for 7 consecutive days and together with one of their parents, they completed the Flemish Physical Activity Questionnaire. Parents filled out a questionnaire concerning their child’s psychosocial factors toward PA (i.e. parental attitude toward their child’s PA, parental social norm toward their child’s PA, parental support, friend support, children’s self-efficacy, and perceived benefits and barriers toward sports and PA). Neighborhood walkability was calculated using geographical information systems (GIS). Multilevel cross-classified analyses were conducted.

Results

Of the 42 investigated interactions between neighborhood walkability and psychosocial factors in relation to PA among children, only 7 significant interactions were found of which 3 were only significant among children from low-income neighborhoods.

Parental support and self-efficacy were positive correlates of children’s PA in high- and low-income neighborhoods independent of the level of walkability, but effect sizes were small.

Conclusions

The hypothesis that walkability would be more strongly related to PA among children with negative psychosocial profiles could not be confirmed and in general, psychosocial factors and objective walkability did not interact in relation to children’s PA. Focusing on parental support and self-efficacy towards PA can possibly cause small effects on children’s PA in both high- and low-walkable neighborhoods, as well as in high- and low-income neighborhoods.

Neighbourhood environment, physical activity, quality of life and depressive symptoms in Hong Kong older adults: a protocol for an observational study

INTRODUCTION

The neighbourhood environment can assist the adoption and maintenance of an active lifestyle and affect the physical and mental well-being of older adults. The psychosocial and behavioural mechanisms through which the environment may affect physical and mental well-being are currently poorly understood.

AIM

This observational study aims to examine associations between the physical and social neighbourhood environments, physical activity, quality of life and depressive symptoms in Chinese Hong Kong older adults.

METHODS AND ANALYSES

An observational study of the associations of measures of the physical and social neighbourhood environment, and psychosocial factors, with physical activity, quality of life and depressive symptoms in 900 Hong Kong older adults aged 65+ years is being conducted in 2012-2016. The study involves two assessments taken 6 months apart. Neighbourhood walkability and access to destinations are objectively measured using Geographic Information Systems and environmental audits. Demographics, socioeconomic status, walking for different purposes, perceived neighbourhood and home environments, psychosocial factors, health status, social networks, depressive symptoms and quality of life are being assessed using validated interviewer-administered self-report measures and medical records. Physical functionality is being assessed using the Short Physical Performance Battery. Physical activity and sedentary behaviours are also being objectively measured in approximately 45% of participants using accelerometers over a week. Physical activity, sedentary behaviours, quality of life and depressive symptoms are being assessed twice (6 months apart) to examine seasonality effects on behaviours and their associations with quality of life and depressive symptoms.

ETHICS AND DISSEMINATION

The study received ethical approval from the University of Hong Kong Human Research Ethics Committee for Non-Clinical Faculties (EA270211) and the Department of Health (Hong Kong SAR). Data are stored in a password-protected secure database for 10 years, accessible only to the named researchers. Findings will be submitted for publication in peer-reviewed journals.
