What the trial was testing
The SELECT enrolled 17,604 patients with obesity. The study was sponsored by Novo Nordisk and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
20% lower risk of heart attack, stroke, or cardiovascular death.
New England Journal of Medicine · 2023 · NCT03574597
These findings — that of heart attack, stroke, or cardiovascular death in overweight adults with heart disease — were published in the New England Journal of Medicine and represent the headline result of the study.
Researchers tracked outcomes across 17,604 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with obesity, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Semaglutide (Wegovy) is FDA-approved both for chronic weight management and to lower the risk of heart attack and stroke in adults with overweight or obesity and existing heart disease. The most common side effects are nausea and stomach upset that ease over time. Ask your doctor or cardiologist whether you qualify.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Strengthening Healthy Emotional Co-regulation of Mothers With PCOS and Obesity and Their Infants
It is both timely and important to invest in interventions that can improve healthy emotional co-regulation. It is proposed to evaluate the feasibility and limited efficacy of an adapted, brief, multimodal intervention: ECoFam (Emotional connection and Co-regulation for Families). Evidence from the US suggests intervention effects on maternal and infant outcomes that are large in effect size (i.e., Cohen's d \>0.6 for increasing emotional connection and decreasing maternal depressive symptoms) (21-23). The study results will directly translate evidence into practice and, if found feasible, allow rapid scaling-up. Objectives: 1. Build capacity for implementation of a novel diagnostic screening tool for emotional co-regulation, the uWECS, as part of clinical follow-up for mother-infant dyads with high fibrobesity risk in Finland. 2. Test the feasibility and limited efficacy of the brief, multimodal ECoFam intervention to foster healthy emotional co-regulation between mothers with PCOS and obesity and their infants.
BrainWeighve App Feasibility Study
Childhood obesity within the United States has been a growing concern over the past number of years, and if not addressed, leads to detrimental health outcomes for youth as they move into adulthood. The literature suggests that over-eating, especially when framed in terms of food addiction, plays a key role in this epidemic; however, treatment options are time intensive, posing a profound logistical barrier for both the child and parent and often limits or prevents engagement. As research within the field of mHealth has grown, technology-based interventions have gained traction, specifically interactive smartphone applications (apps). Displacement theory, although not new, has been understudied yet provides a strong explanation and treatment plan for addictive type behaviors. The core of this theory posits that problems which one feels they cannot face nor avoid leads to repetitive and irrepressible behaviors; however, if a healthy coping behavior can be learned and utilized, then the unhealthy behavior will cease. The theory lends itself well to being adapted into an mHealth format, making it more easily accessible and more widely used. Grounded in displacement theory, the proposed study aims to develop an app-based weight loss intervention for adolescents with obesity. Information gained regarding the feasibility and acceptability of such an intervention can potentially be replicated and applied to other populations with various addictive behaviors. Helping those with addictive behaviors in a format that has little to no logistical barriers can have a substantial impact on public health. A novel smartphone app will be designed by key stakeholders and refined through the course of the study. 38 total adolescents (14-21 years old) with %BMIp85 will be recruited via various sources (e.g., clinic referrals, flyers, social media advertising) to participate in one of two stages of the study: the beta testing stage or the trial stage. Beta testing will enroll one group of eight teens to test the app for three weeks; participants will be assessed in-person pre- and post-intervention. After each group, the app will be modified to incorporate their feedback in order to promote youth engagement. The trial stage will enroll 30 adolescents to participate in a four-month intervention; participants will complete three assessments, baseline, post-intervention (both in-person) and one-month post-intervention (either in-person or virtually). The study will examine engagement and satisfaction with the app, as well as the intervention's impact on clinical outcome measures (weight and BMI, diet and snacking, and addictive behaviors related to food and substance use) and potential mediators/moderators (motivation for change, perceived stress, and distress tolerance).
