Wave I (2002-2003)
The Wave I community survey was developed by a survey subcommittee made up of members of the Steering Committee that worked together for over a year to develop and pretest the survey instrument. In doing so, the subcommittee drew on results from community focus groups, the literature on cardiovascular risk and protective factors, and extensive discussion. In 2002-2003, we conducted our first community survey, using a stratified, two-stage equal probability sample of occupied households in three areas of Detroit: eastside, northwest, and southwest. In each of the three areas, all respondents lived in a compact area with at most a 1.3 mile radius. The sample was designed to obtain 1,000 completed interviews with persons ages 25 years and older in the three study areas. We completed interviews with 918 residents of the three study areas. Of those, 511 interviews were completed with non-Hispanic Black, 194 non-Hispanic white, and 178 Latino/a residents of the three study areas.
The survey included the following information: demographic information (age, income, education); self reported stressors (life events, environmental stress, discrimination, safety stress, financial stress); assessments of health related behaviors; self-reported exposure to airborne particulate matter in home and workplace settings; indicators of social support, integration and community connectedness; responses to stressful life conditions; self reported medical history and conditions; anthropomorphic and hemodynamic measures; and nutrition data collected using a food frequency questionnaire. Survey respondents received detailed information about their dietary risks for heart disease, based on self reported dietary intakes from the survey. (A detailed list of scales used in the survey and supporting documentation is available in Kannan et al. 2007.)
Wave II (2008-2009)
The Wave II community survey was conducted in 2008 and 2009. This survey followed up with community residents who had completed Wave I community survey, and who remained living in the same household in which they had resided in 2002-2003. In addition, interviews were conducted with a subset of new residents living in the households sampled for Wave I, but where the original survey respondent was no longer in residence. This survey contained many of the same items included in the Wave I survey, but also included a more detailed assessment of: 1) physical activity; and 2) respondents perceptions of the walkability of their neighborhoods. This survey will enable us to examine closely change over time in several factors associated with heart disease among residents of our study communities, and to better understand connections between physical activities and characteristics of the neighborhoods.
