ABSTRACT
Background:
Studies assessing the impact of built environments on body weight are often hobbled by limited power to detect residential effects that are modest for individuals but may nonetheless comprise large attributable risks.
Objective:
We used data extracted from electronic health records to construct a large retrospective cohort of patients who had follow-up for up to 12 years. This cohort will be used to explore both the impact of moving between environments and the long-term impact of changing neighborhood environments.
Methods:
We identified members with at least 12 months of Kaiser Permanente Washington membership and at least one weight measurement in their records during a period in which they lived in King County, Washington. Information on member demographics, address history, diagnoses, and clinical visits data (including weight) were extracted. This paper describes the characteristics of the adult (18 to 89 years old) cohort constructed from these data.
Results:
We identified 229,755 adults representing nearly 1.2 million person-years of follow-up. Mean age at baseline was 45, and fifty-eight percent (n=133,326) were female. Nearly a quarter of people (n=55,150) moved within King County at least once during follow-up, representing 84,698 total moves. Members tended to move to new neighborhoods matching their origin neighborhoods on residential density and property values.
Conclusions:
The Moving to Health study adult cohort is a very large cohort based in King County, Washington. Future analyses will directly examine associations between neighborhood conditions and longitudinal changes in body weight and
