PCORI Answers Critical Questions
PCORI funds studies to help patients and those who care for them answer a range of questions about obesity, such as:
Clinician: Several of my patients who have obesity have asked me how they can lose weight. Which are the most effective ways to help them do so and live healthier lives?
Caregiver: I’m about to have my first child and I’ve heard that giving my baby antibiotics in the first two years of her life could increase her chance of becoming overweight later. Does that risk vary depending on how much of these drugs she receives and how often?
Benefits Manager: We’re hearing that weight loss surgery can improve people’s health, which could mean fewer sick days. But which of the several weight loss surgeries is most effective?
Study Results that Support Better-Informed Decisions
|Key Lifestyle Changes Can Help Patients with Obesity Lose More Weight, Keep It Off Longer, Study Finds
Reporting in the New England Journal of Medicine, the PROPEL Study found that an intensive healthy lifestyle intervention—which included health coaches embedded in primary care practices working with patients to develop healthy habits—resulted in patients losing significantly more weight than those who received usual care from their primary care clinics, and they kept more weight off at two years later. The results show that successful weight loss can be achieved in primary care settings in a highly underserved population who have significant barriers to obtaining health care services.
|Five-Year Outcomes for Common Bariatric Surgeries
The PCORnet® Bariatric Study—which is using data from PCORnet, The National Patient-Centered Clinical Research Network—to study outcomes among patients who undergo common weight-loss surgeries has published several papers in prominent medical journals. The most recent clinical findings, published in JAMA Surgery, are on diabetes remission outcomes among patients who underwent gastric bypass and gastric sleeve surgeries. Another article, also published in JAMA Surgery, details the five-year outcomes of patients who underwent either gastric bypass or adjustable banding, finding that gastric bypass patients were significantly more likely than gastric sleeve patients to end up back in the hospital in the years following surgery.
Obesity Study Spotlights
This study found that children who were overweight achieved healthier weights after their parents received information about behavior change, and after their clinicians got help counseling families.

This study in the rural Midwest tests conventional delivery of obesity treatment in clinics by primary care physicians against two other approaches in which care is enhanced by obesity counseling specialists and patient support.
