Innovative, online automated obesity treatment program shows weight loss results - Video

The current study is one of the first times that a fully-automated obesity treatment program has been tested pragmatically in a large, primary care network with clinicians responsible for identifying patients, providing the program, and supporting its use.

As part of routine primary care, healthcare providers and 16 nurse care managers offered a no-cost, online, obesity treatment program named Rx Weight Loss (RxWL) to 1,765 patients at the Rhode Island Primary Care Physicians Corp.—a primary care practice organization that includes approximately 60 practices with 100 physicians. Eligible patients were aged 18 to 75 years old with a body mass index (BMI) of ≥ 25 kg/m2 and internet access. The majority of the 464 patients who ultimately enrolled in the program and engaged in treatment were White and female. Two percent of the sample identified as Hispanic or Latinx ethnicity, and Black/African-American. The program included 12 weekly online sessions, a self-monitoring program, and automated feedback.

The average 12-week weight loss was 5.10%. Researchers note that most e-health obesity treatments report average weight losses of 2.5% initial body weight at 12 or 24 weeks.

Patients who reported their weight on all 12 weeks achieved an estimated weight loss of 7.2% compared to 3.4% in those submitting less frequently. Patients who accessed all 12-video lessons achieved an estimated weight loss of 8% compared to 4.2% for patients who accessed fewer lessons. Neither BMI, sex nor identification with a racial/ethnic minority group were associated with these measures of engagement but age was associated with a greater number of lessons viewed.

The study's authors observe that further research will help determine whether the disproportionately small number of men and racial/ethnic minorities enrolled in this program results from the characteristics of the patients seen in these practices, a bias on the part of the clinicians in referring patients to the program, or lack of interest in weight loss expressed by these patients. Efforts to increase initial engagement with the program will help determine the effectiveness of the program in patients who may be less motivated to lose weight.
