The purpose of this study was to assess effects of a mobile coaching system on glycated hemoglobin (HbA1c) levels in younger versus older patients over 1 year. Participants (n = 118) included adult patients with Type 2 diabetes cared for by community physicians. Intervention patients received mobile phone coaching and individualized web portal. Control patients received usual care. Patients were stratified into two age groups: younger (<55 years) and older (≥ 55 years). The intervention resulted in greater 12-month declines in HbA1c, compared with usual care, for patients in both age groups (p < .0001). Among older patients, HbA1c changed by -1.8% (95% confidence interval CI = -2.4, -1.1) in the intervention group and -0.3% (95% CI = -0.9, +0.3) in the control group. Among younger patients, HbA1c changed by -2.0% (95% CI = -2.5, -1.5) in the intervention group and -1.0% (95% CI = -1.6, -0.4) in the control group. The mobile health intervention was as effective at managing Type 2 diabetes in older adults as younger persons.
