Obesity–housing nexus: an integrative conceptualization of the impact of housing and built environment on obesity

Obesity has emerged as one of the most significant public health challenges of the 21st century, with its prevalence increasing at an alarming rate globally. While individual factors such as diet and physical inactivity are well-known contributors, the built environment, particularly housing, plays a critical yet understudied role in shaping obesity-related behaviors. This study examines the multilayered relationship between housing and obesity, focusing on built and neighborhood environment, affordability, and the social environment. Poor housing quality, such as overcrowding and inadequate ventilation, can potentially lead to chronic stress and sedentary behaviors, while housing design influences physical activity through characteristics such as design features and outdoor spaces. Housing location affects access to amenities such as parks and healthy food options, with disparities in access contributing to obesity in low-income areas. Similarly, neighborhood walkability, influenced by infrastructure and land use, encourages active transportation and recreation. Housing affordability also impacts dietary choices and access to recreational facilities, particularly for low-income families. Moreover, the social environment within housing communities can foster or hinder healthy behaviors through social networks and community engagement. This study emphasizes the need for health-conscious urban planning and policies that address these housing-related factors to combat obesity and promote healthier lifestyles. By integrating these Obesity–Housing Nexus, policymakers can create environments that support physical activity, healthy eating, as well as overall health and well-being.
