Question: Does a combined intervention, including an online weight management program integrated with population health management (additional support and outreach from nonclinical staff), increase weight loss at 12 months among primary care patients compared with the online program only and usual care?
Findings: In this cluster randomized trial of 840 patients with overweight or obesity and a diagnosis of hypertension or type 2 diabetes, the mean weight loss at 12 months was 1.2 kg in the usual care group, 1.9 kg in the online program only group, and 3.1 kg in the combined online program with population health management group. The difference in weight loss between the combined intervention group and either the usual care group or the online program only group was statistically significant.
Meaning: Combining population health management with an online program resulted in a small but statistically significant greater amount of weight loss at 12 months compared with usual care or the online program only.
