Redefining Age-Friendly Neighbourhoods: Translating the Promises of Blue Zones for Contemporary Urban Environments

The longevity and healthy ageing observed in Blue Zones offer valuable insights for contemporary urban neighbourhood planning and design. This paper reviews the age-friendly features of the built environment in Blue Zones, aiming to translate these insights into actionable strategies for urban neighbourhood development. Employing a systematic literature review and Convolutional Neural Networks (CNNs) analysis of Google Street View imagery, this study assesses the built environments in Blue Zones, including housing, public spaces, and transportation systems. Key findings highlight the presence of adaptable housing, building designs that foster a connection with nature, and semi-public spaces that encourage social interaction and physical activity. A notable emphasis on walkability and limited public transport access was observed. The CNN analysis corroborated these findings, providing a quantitative view of age-friendly features. This research contributes to the academic discourse in urban planning and design by providing practical insights for developing age-friendly neighbourhoods, inspired by Blue Zones. It concludes by offering policy advice and future research directions for creating sustainable and inclusive urban environments conducive to ageing populations.

Cardiovascular Aging and Longevity: JACC State-of-the-Art Review

Cardiovascular aging and longevity are interrelated through many pathophysiological mechanisms. Many factors that promote atherosclerotic cardiovascular disease are also implicated in the aging process and vice versa. Indeed, cardiometabolic disorders such as hyperglycemia, insulin resistance, dyslipidemia, and arterial hypertension share common pathophysiological mechanisms with aging and longevity. Moreover, genetic modulators of longevity have a significant impact on cardiovascular aging. The current knowledge of genetic, molecular, and biochemical pathways of aging may serve as a substrate to introduce interventions that might delay cardiovascular aging, thus approaching the goal of longevity. In the present review, the authors describe pathophysiological links between cardiovascular aging and longevity and translate these mechanisms into clinical data by reporting genetic, dietary, and environmental characteristics from long-living populations.
