Week 7 : Neighborhood and SocHI Design

Universal Design

The design of products and environments to be usable by all people, to the greatest extent possible, without adaptation or specialized design

Equitable Use

Universal Design Principle 1: The design is useful and marketable to people with diverse abilities

Flexibility in Use

Universal Design Principle 2: The design accommodates a wide range of individual preferences and abilities

Simple and Intuitive Use

Universal Design Principle 3: Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or current concentration level

Perceptible Information

Universal Design Principle 4: The design communicates necessary information effectively to the user, regardless of ambient conditions or the user's sensory abilities

Tolerance for Error

Universal Design Principle 5: The design minimizes hazards and the adverse consequences of accidental or unintended actions

Low Physical Effort

Universal Design Principle 6: The design can be used efficiently and comfortably and with a minimum of fatigue

Size and Space for Approach and Use

Universal Design Principle 7: Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility

Accessibility

A design approach that focuses on eliminating barriers to ensure equality of access — considered a "separate but equal" approach

Inclusive Design

A design process that incorporates the point of view of users

How does Universal Design differ from Accessibility?

Universal Design goes beyond accessibility to benefit everyone without stigma, focusing on common use and aesthetics — aspiring to equality of access without a "separate but equal" solution

What are the 3 reasons neighborhood health research grew?

(1) Individual-level explanations of illness are insufficient

(2) neighborhoods may explain race/ethnic and social inequalities in health

(3) non-health policies (housing, urban planning) can affect health through neighborhood contexts

Neighborhood Physical Environment

Includes environmental exposures, food and recreational resources, built environment, aesthetic quality/natural spaces, services, and housing quality

Neighborhood Social Environment

Includes safety/violence, social connections/cohesion, local institutions, and norms

How do neighborhoods affect health?

Through two main pathways: behavioral mediators (diet, physical activity) and stress responses, shaped by both physical and social neighborhood environments

What did early studies using census proxies find about neighborhood disadvantage and health?

Living in a poor, deprived, or disadvantaged neighborhood is generally associated with greater mortality, poorer self-reported health, adverse mental health, greater chronic disease prevalence, and adverse child health outcomes

Limitation of census proxy studies

They cannot identify which specific neighborhood-level features matter most for health, making it difficult to understand causal mechanisms or design targeted interventions

What built environment features are linked to more walking for transportation?

Greater population density, more land use mix, and proximity to non-residential destinations are consistently linked to more walking for transportation

What did reviews find about physical activity resources and physical activity levels?

About 80% of studies found significant positive relationships between the presence of physical activity resources (parks, recreation settings) and residents' physical activity levels

Food Deserts

Areas with poor access to supermarkets and healthy food retail

associated with worse diet quality and higher BMI

How does neighborhood food environment relate to diet?

Residents with better access to supermarkets and healthy food stores tend to have healthier diets

proximity to fast food restaurants is associated with worse diet quality

How does built environment relate to BMI/obesity?

The preponderance of evidence suggests poorer physical activity environments and poorer food access are associated with higher BMI

How is neighborhood physical environment linked to depression?

Physical disorder/decay and neighborhood problems (traffic, noise, lack of green space) are associated with increased depressive symptoms across multiple studies

Social Cohesion and Mental Health

Greater social connections between neighbors, including social cohesion and reciprocal exchanges, are protective against depression in 11 of 16 studies reviewed

Collective Efficacy

A neighborhood's shared willingness to intervene for the common good

associated with lower BMI and better physical health outcomes in several studies

Residential Instability

A neighborhood characteristic hypothesized to reduce informal social ties

linked to depression in multiple studies

Moving to Opportunity Study (MTO)

A natural experiment that randomized poor families into non-poor neighborhoods

found no effects on most adult physical health outcomes but did find lower BMI and better mental health among those who moved

Key methodological challenge in neighborhood health research

Distinguishing neighborhood effects from individual-level characteristics (income, education) that also predict health and determine where people live

Selection bias in neighborhood health studies

Individuals may select into neighborhoods based on health or behavioral preferences, making it hard to establish causation from observational data

What are "activity spaces"?

The set of places individuals come into contact with as a result of their routine activities — these may not match residential neighborhood boundaries

Why are neighborhoods a primary mechanism by which SES affects health?

Poor neighborhoods have disproportionate exposure to harmful conditions, lack services enabling upward mobility, and racial segregation reinforces these class differences

Bronfenbrenner Ecological Model

A model of health influence with nested levels: genetics, individual, relationships, community/environment, and society/law/policy — neighborhoods operate at the community/environment level

What social environment features protect against poor health?

Close-knit neighborhoods with social connections enable collective goal achievement, information exchange, and informal social controls — all associated with better health outcomes

Physical Disorder and Health

Disorderly neighborhoods (noise, litter, graffiti, crime, poorly maintained buildings) discourage healthy behaviors like exercise and social activity, and are associated with worse mental health

Third Places

Gathering spaces outside home and work (eateries, libraries, religious institutions, arts venues) that support social connections and neighborhood health

Why is the decline of third places a health concern?

Studies during COVID-19 found in-person contact improved health more than virtual contact

the loss of third spaces reduces opportunities for social interaction that buffer stress and promote wellbeing

Klinenberg's "Social Autopsy"

A method studying the social and political conditions that explain differential mortality — used to analyze Chicago's 1995 heat wave, finding that neighborhood social and physical conditions (not just individual factors) predicted who died

What explained differences in heat-wave mortality across similar Chicago neighborhoods?

Differences in abandoned buildings, violent crime, street-level activity, social connection to city government, and proportions of elderly living alone

Press-Competence Model (Lawton-Nahemow)

A theory stating that health ability = match between individual competence and environmental demands (press)

as competence decreases, the zone of suitable environments narrows and environmental modifications become more important

What happens as individual competence decreases according to the Press-Competence Model?

The zone of adaptation narrows, suitable environments become more limited, and environmental modifications become more critical to maintaining functioning and wellbeing

Person-Environment Fit

The dynamic process by which individuals adapt to environments and modify environments to fit their needs

chronic disease can challenge this adaptive capacity

Challenging Environments and Health

Difficult environments can lead to negative health behaviors, shrinking of life space, and worsening physical and mental health — while environmental modifications can improve functioning, independence, and wellbeing

Why do economic resources matter for environmental modification?

Differential economic and social resources contribute to the ability to make home and neighborhood modifications — reinforcing health inequalities by SES

Racial Segregation and Health

Segregated neighborhoods are more likely to be low-SES, have worse housing, and have lower access to economic opportunities — exacerbating class-based health differences

Open-Air Treatment Movement

18th–19th century approach using ventilation/fresh air to treat tuberculosis

influenced architectural design and was revived during COVID-19 for outdoor dining and school ventilation

DeafSpace Design (Gallaudet University)

An example of inclusive design that redesigns campus architecture according to the specific spatial and visual communication needs of deaf users — demonstrating how design can be tailored to user populations

Enabling Village, Singapore

A 2016 universally designed inclusive space integrating education, work, training, and retail for people with disabilities

uses wayfinding touchpoints and slopes instead of stairs as a universal design example

How does Universal Design relate to neighborhood health?

Environments designed using UD principles remove physical barriers that limit access to healthy food, recreation, social participation, and services — thereby reducing health disparities tied to disability or physical capacity

Manski's Typology of Group Effects

Three types: (1) endogenous effects (group outcomes affect individual outcomes)

(2) contextual effects of group composition

(3) environmental effects of exogenous neighborhood features — neighborhood health research primarily targets environmental effects

Why is defining "neighborhood" difficult for health research?

Relevant spatial contexts vary by the process studied — social interaction operates at small scales while food shopping operates at larger scales

there is no single correct definition and boundaries are often "fuzzy"

Life Course and Neighborhood Health

Neighborhood disadvantage early in life may affect later health by shaping access to education and occupational opportunities, while those same factors later determine re-exposure to neighborhood poverty — creating complex mediation and confounding

Agent-Based Models in Neighborhood Research

Complex systems methods that simulate dynamic interactions between individuals and environments

useful for understanding feedback loops in how neighborhood health patterns emerge, complementing observational studie
