Award Description: In a prospective longitudinal study, it is hypothesized that the built environment's walkability will impact the social environment's collective efficacy, and that these environmental variables together will influence physical activity. Controlling for diet, physical activity is hypothesized to predict adiposity, inflammation, and insulin resistance; and these in turn will predict progression in metabolic syndrome indicators. While these relationships have been tested separately, this application proposes an integrated and interdisciplinary test of the relationship among these variables. Hispanic immigrants are selected for this study because Hispanics have disproportionately high rates of diabetes. Moreover, for very recent immigrants, weight increases rapidly as a function of time in the US. Participants will be 390, 30-45 year-old recent immigrants who do not meet criteria for metabolic syndrome. Built environment's walkability will be assessed through self-reports, and objectively using the .25 mile radius surrounding the participant's residence. Participants will be assessed on self-reported measures of collective efficacy, physical activity, diet, and biculturation, and objective measures of physical activity, adiposity, inflammation, insulin resistance, and metabolic syndrome indicators. Variables in the primary analyses will be continuously distributed. Growth curves will be estimated using growth curve methodology in a structural equations framework using Mplus 3.
Project Description: Since 08/01/09, the team has worked on researching and contacting other potential participant recruitment sites, with the goal of increasing the number of eligible participants. A list of agencies serving immigrants and refugees in Miami-Dade County has been drafted, and thus far, several organizations that serve Cuban immigrants have agreed to distribute study brochures to their clients, including a local public health clinic and a multi-site, job training and placement program. A total of 18 participants were recruited in August 2009, and 14 of these were eligible after Baseline. This monthly recruitment rate is 4-6 participants higher than for the months of May, June or July 2009.
