Neighborhood-Level Influences on All-Cause Mortality

To test the independent and interrelated effects of the neighborhood social environment, the neighborhood physical environment, and individual risk factors in predicting all-cause and cardiovascular disease mortality.

Study Overview

• Status: Completed
• Conditions: Heart Diseases; Cardiovascular Diseases

Detailed Description

BACKGROUND:

The study examines how social and physical features of neighborhoods interact with individual factors to influence disparities in health, an important but understudied area of research. This project will create a rich new database where individuals' socioeconomic status (SES) and health indicators are linked with characteristics of their specific neighborhoods and their subsequent mortality. Thus, it builds on an important exiting data base to create a contextual-level database with information about mortality.

DESIGN NARRATIVE:

Few studies have examined how social and physical features of neighborhoods interact with individual factors, e.g., health behaviors and socioeconomic status (SES), to influence disparities in health. The investigators propose to test the independent and interrelated effects of the neighborhood social environment (e.g., neighborhood SES, social disorganization, Hispanic concentration, crime rates), neighborhood physical environment (e.g., housing conditions, availability of goods and services such as licensed alcohol distributors, fast food restaurants, grocery stores, gun shops, educational resources, recreational facilities, banking/lending institutions), and individual risk factors in predicting all-cause and cardiovascular disease (CVD) mortality in women and men. They will conduct a prospective mortality follow-up study of 8,847 white (non-Hispanic) and Hispanic women and men who participated in the Stanford Heart Disease Prevention Program (SHDPP), also referred to as the Stanford Five-City Project. This population-based CVD study included a random sample of women and men aged 25-74 who participated in one of five cross-sectional surveys (1979-1990) and were from four socioeconomically diverse California cities. The SHDPP is recognized for its comprehensive and well-standardized survey and physiologic measures that include SES (education, income, occupation), CVD risk factors (e.g., smoking, high cholesterol and saturated fat), psychosocial factors, and other health-related measures. The investigators propose to match survey data to death records for all-cause and CVD mortality endpoints, and link geocoded addresses to census data and archival data for measures of the neighborhood social and physical environment. This work would create a new database where individuals' SES and health indicators are linked with characteristics of their specific neighborhoods. Based on their empirical findings, they will identity neighborhoods currently at high and low risk for mortality, then conduct focus groups and map neighborhood environments (e.g., social, physical, and service features) to create a geographic information system (GIS). These two activities will hopefully extend their empirical findings, generate new hypotheses, and guide the development of their Community Outreach and Education Program (COEP). The COEP will build on their collaborative partnerships with members of the study cities, health advocates, and health agencies that serve low SES and medically under served populations. With the involvement of these partners, they will integrate their empirical findings with knowledge from existing studies and disseminate results via the Internet, media, targeted mailings, and programs offered by the California State and local county health departments in the four study cities.
