This study was supported by the National Heart, Lung, and Blood Institute grant no. UO1-HL087085.

Healthways developed the website for both interventions in collaboration with Hopkins investigators and provided coaches for the call-center directed intervention. Healthways also provided some research funding to supplement NIH support.

Johns Hopkins University has an institutional consulting agreement with Healthways. Under this institutional agreement, the University is entitled to fees for consulting services.

Those faculty investigators who participate in the consulting services receive a portion of the University fees, either as research support or salary supplement as determined by their supervisors.

The terms of this arrangement are managed by the Johns Hopkins University in accordance with its conflict of interest policies.
