Development of a physical performance summary score in middle age: Findings from the CARDIA Function study.

Few physical performance batteries exist that appropriately evaluate physical limitations in middle-aged adults. We aimed to develop a physical performance summary score that is appropriate for use in epidemiology studies of middle-aged adults using data from the Coronary Artery Risk Development in Young Adults (CARDIA) Function study, which assessed self-reported function (PROMIS-SF20a) and physical performance measures (gait speed, balance, lower-body strength, grip strength, and cardiovascular endurance). The CARDIA Physical Performance (CAPP) score was developed using sex-specific quartiles, assigning points based on these quartiles (0 for not attempted, 1-4 for each quartile), and summing points across all performance measures (0-20, higher scores reflect greater performance).

Multimorbidity trajectories in early adulthood and middle age: Findings from the CARDIA prospective cohort study.

Background: Multimorbidity research has focused on the prevalence and consequences of multimorbidity in older populations. Less is known about the accumulation of chronic conditions earlier in the life course.

Methods: We identified patterns of longitudinal multimorbidity accumulation using 30 years of data from in-person exams, annual follow-ups, and adjudicated end-points among 4,945 participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study.

Trajectories of Physical Resilience Among Older Veterans With Stage 4 CKD.

Rationale & Objective: Although functional impairment is common among older adults with chronic kidney disease (CKD), functional reserve before an acute health event and physical resilience after the event have not been characterized in this population. The purpose of this study was to identify distinct patterns of physical function before and after an acute health event among older veterans with stage 4 CKD.

Study Design: Prospective cohort study.

The potential of mHealth for older adults on dialysis and their care partners: What's been done and where do we go from here?

Self-care, or the dynamic, daily process of becoming actively involved in one's own care, is paramount to prevent and manage complications of end-stage kidney disease. However, many older dialysis patients face distinctive challenges to adequate engagement in self-care. One promising strategy for facilitating self-care among older dialysis patients and their care partners is the utilization of mobile health (mhealth).
