Objective:

This community-based participatory research (CBPR) project is studying childhood obesity in relation to structural features and endocrine disruptor (ED) exposures in the urban built environment of East Harlem. The specific objective of this project is to assess accessibility to physical activity resources and to healthy foods.

Progress Summary:

The first step was to develop maps that locate every play-space, open area, and food source in East Harlem to use as measures of the built-environment in our community. These maps will be the basis of a geographic information system (GIS) to assess obesity and physical activity among children in our studies. Quantitative physical activity is being assessed using a newly developed protocol that records daily pedometer readings and activity diaries. The protocol was evaluated in week-long diaries among 30 children in Project 1. Children’s usage patterns of EDs are being determined through a “product-use” questionnaire (developed in our CBPR). We have completed a 6-month study to evaluate biomarker protocols in 34 6- to 8-year-old children of phthalates, phenols, and phytoestrogens and the sources of those chemicals. Reported product usage is being compared with children’s body burdens of new-age EDs as determined in urine. Early results show maximum levels greater than 3000 mg/L of at least one analyte and median levels greater than100 mg/L for most of the phthalate, phytoestrogen, and phenol families of EDs. Findings will guide sample collection and analysis for this project and project R831711C002, as well as lead to an improved product-use questionnaire. A 3-year longitudinal study has begun in 150 6- to 8-year-old children to evaluate risk for obesity in relation to built environment factors and ED exposures.

Future Activities:

In preparation for Year 3, we will review and modify the main questionnaire for the first year follow-up visit. We plan to conduct follow-up dietary recalls on one-half of our sample in Year 3 and the other one-half in Year 4. We will continue to examine temporal variability and reliability of the EDs to determine optimal urine sampling strategies; examine ED exposure levels and their relationship to diet, physical activity level, and weight; and compare availability, proximity, and density of resources (GIS data) with individual level factors (neighborhood questionnaire) such as access, knowledge, utilization, dietary quality, and physical activity level.
