View Abstract

BACKGROUND

Scalable, low-cost weight management strategies are needed in primary care. We conducted a pragmatic, cluster-randomized controlled trial to examine the effectiveness of an online weight management program integrated with population health management support.

METHODS

We adapted an online weight management program and integrated it with population health management support in 15 primary care practices (24 clinics). We randomized the 24 clinics to usual care (UC), online program alone (OP), or combined intervention (CI). Eligible participants had to be ages 20 to 70 and have a recent primary care visit, body mass index (BMI) ≥ 27 and < 40 kg/m, and a diagnosis of hypertension or type 2 diabetes. Participants attended routine visits and completed surveys over 18 months. The primary outcome is absolute weight change at 12 months (± 90 days) after enrollment, calculated from weights measured at primary care visits and recorded in the electronic health record.

RESULTS

We enrolled 840 participants between July 2016 and August 2017 (326 UC, 216 OP, and 298 CI.) At enrollment, participants' mean age was 59.3 years, their mean weight was 203.1 pounds, and their mean BMI was 32.5 kg/m; 60% of participants were female, 76% were white, 96.4% had hypertension, and 24.4% had type 2 diabetes.

CONCLUSION

It is feasible to adapt an online weight management program and integrate it with population health management support in primary care. The results of this trial will provide valuable information about the effectiveness of these strategies in primary care settings. ClinicalTrials.govregistration number:NCT02656693.
