Associations between perceived neighbourhood problems and quality of life in older adults with and without osteoarthritis: Results from the Hertfordshire Cohort Study

[Environnement résidentiel et vieillissement en santé : le rôle de l'activité physique et de la participation sociale]

Le vieillissement démographique est un des défis majeurs du 21e siècle. Il pose directement la question du « vieillissement en santé », un processus aidant les personnes âgées à rester en bonne santé et indépendantes le plus longtemps possible. L'influence des facteurs environnementaux sur ce processus peut varier selon les individus et leurs comportements. L'enchevêtrement de ces facteurs représente un défi autant théorique que méthodologique. Cet article a pour objectifs i) de quantifier les associations entre l'environnement physique et social du quartier des personnes âgées et leur vieillissement en santé et ii) d'examiner si leur activité physique et leur participation sociale jouent un rôle de médiation dans ces associations. Si certaines caractéristiques du quartier relatives à la réputation, l'accès aux services, et la cohésion sociale sont associées au vieillissement en santé, il existe un soutien limité à l'idée que les comportements tiennent un rôle d'intermédiaire dans cette relation.

How Are Neighborhood Characteristics Associated With Mental and Physical Functioning Among Older Adults With Radiographic Knee Osteoarthritis?

OBJECTIVE

To examine how neighborhood characteristics are associated with health outcomes among older adults with osteoarthritis.

METHODS

In multilevel, cross-sectional, and longitudinal analyses we examined whether 4 neighborhood characteristics were associated with depressive symptoms and reported knee impact scores, and whether the neighborhood characteristics interacted with race/ethnicity among older adults with radiographic knee osteoarthritis (n = 656 for cross-sectional analyses and n = 434 for longitudinal analyses). The data came from the Johnston County Osteoarthritis Project, a prospective cohort study in North Carolina designed to examine risk factors for osteoarthritis.

RESULTS

Although few longitudinal associations were found, cross-sectional results suggested that greater perceived neighborhood social cohesion (B = -0.04, P < 0.001) and perceived neighborhood resources for physical activity and walking (B = -0.03, P < 0.001) were associated with fewer depressive symptoms, and that greater perceived neighborhood resources for physical activity and walking were associated with higher (better) knee impact scores (B = 0.48, P = 0.008). We also observed 2 significant interactions among neighborhood characteristics and race/ethnicity related to depressive symptoms (P < 0.01); for African American adults, greater perceived neighborhood resources for physical activity and walking were associated with fewer depressive symptoms (B = -0.03, P < 0.001), but for White adults, greater perceived neighborhood safety was associated with fewer depressive symptoms (B = -0.04, P = 0.003).

CONCLUSION

In a sample of older adults with radiographic knee osteoarthritis, neighborhood context mattered, but in nuanced ways. Interventions aiming to improve mental and physical functioning of older adults with knee osteoarthritis can look to this study as evidence for the importance of neighborhood characteristics.

Neighborhood environment, social participation, and physical activity in older adults with lower limb osteoarthritis: A mediation analysis

Older adults with lower limb osteoarthritis (LLOA) are highly dependent on their physical and social environment for being physically active. Longitudinal data from 2286 older adults (M_age = 73.8 years; 50.3% female) in six European countries were analyzed using cross-lagged Structural Equation Modeling (SEM) and multi-group SEM. In cross-sectional analyses, neighborhood resources were associated with physical activity (r = 0.26;p < .001) and social participation (r = 0.13;p = .003). Physical activity at follow-up was associated with neighborhood resources, with this relationship mediated by social participation in people with LLOA (β = 0.018;p = .013). To promote future physical activity, opportunities to socially engage in neighborhoods need to be targeted primarily to people with LLOA.

How can neighborhood environments facilitate management of osteoarthritis: A scoping review

OBJECTIVE

The association between neighborhood environments and health outcomes has long been recognized, but the importance of environmental factors is less well examined in osteoarthritis (OA). We aimed to give an overview of the literature examining the role of neighborhood built environments in the context of OA self-management.

MATERIAL AND METHODS

A literature search between 2000 and 2019 was performed using a scoping methodology. Literature examining the influence of neighborhood built environments on health and other outcomes in people with OA, mixed or unspecified arthritis were screened by two independent reviewers. Seven domains were pre-determined based on the World Health Organization European Healthy Cities Framework. Sub-domains and themes were synthesized from the literature.

RESULTS

We included 27 studies across seven pre-determined domains, 23 sub-domains. We identified 6 key outcomes of physical activity, quality of life, community participation, resource use, psychological health, and other physical health. The majority of studies emphasized the importance of neighborhood built environment on supporting OA self-management, particularly for facilitating physical activity. The impacts on other outcomes were also considered important but were less well studied, especially access to healthy food.

CONCLUSIONS

This review highlights the potential of better using the built environment to support OA management to address many different outcomes. Understanding the impacts of different environments is the first step, and designing new and novel ways to utilize neighborhoods is needed. Implementing strategies and public policies at a neighborhood level may be a more viable way to curb further increases in the OA epidemic than addressing individual factors alone.

The Hertfordshire Cohort Study: an overview

The Hertfordshire Cohort Study is a nationally unique study of men and women born in the English county of Hertfordshire in the early part of the 20 ^th century. Records that detail their health in infancy and childhood have been preserved, their sociodemographic, lifestyle, medical and biological attributes have been characterised in later life, and routinely collected data on their hospital use and mortality have been acquired. This paper provides an overview of the study since its inception in the 1980s, including its methods, findings, and plans for its future.
