Antihypertensive Adherence Trajectories Among Older Adults in the First Year After Initiation of Therapy.

ABSTRACT: BACKGROUND:Adherence to antihypertensives is suboptimal, but previous methods of quantifying adherence fail to account for varying patterns of use over time. We sought to improve classification of antihypertensive adherence using group-based trajectory models, and to determine whether individual factors predict adherence trajectories.
