Telephone Intervention to Improve Diabetes Control: A Randomized Trial in the New York City A1c Registry.

Introduction: Scalable self-management interventions are necessary to address suboptimal diabetes control, especially among minority populations. The study tested the effectiveness of a telephone behavioral intervention in improving glycemic control among adults with diabetes in the New York City A1c Registry.

Design: RCT comparing a telephone intervention to print-only intervention in the context of the A1c Registry program.

Baseline characteristics and Latino versus non-Latino contrasts among Bronx A1C study participants.

We describe baseline demographic and psychosocial characteristics of low-income, diverse diabetes adults enrolled in a telephonic intervention trial. Environment for the study was New York City (NYC) A1C Registry program. Baseline data were analyzed from 941 participants randomized to either telephonic/print or print-only intervention to improve glycemic control.
