Ipsos fielded an online, 30-minute, self-administered, cross-sectional survey from May 9 to 25, 2025 using the probability-based KnowledgePanel^®. Invitations were sent to 15,149 panelists, resulting in 1,778 completes among adults 18-70, with 271 people with obesity who are current/past obesity medication users.

A secondary follow up recontact online, 5-minute, self-administered survey was conducted from August 1 to 13, 2025, by Ipsos using a subset of respondents from the original poll who agreed to be recontacted for further research, resulting in 498 completes among adults 18-70, with 74 people with obesity who are current/past obesity medication users.

Ipsos fielded an online, 30-minute, self-administered, cross-sectional survey among Healthcare Professionals (HCPs) in the United States during the period between May 9 to 25, 2025. Respondents were recruited from opt-in panels of HCPs across the country. In order to participate in the survey, all HCPs had to be a practicing Primary Care Physician/General Practitioner/Family Medicine or Internal Medicine [PCP], Nurse Practitioner / Physician Assistant [NP/PA] in a Primary Care Physician/General Practitioner/Family Medicine or Internal Medicine office, Endocrinologist/Diabetologist [Endocrinologist], Obstetrician and Gynecologist (OB/ GYN), Nephrologist, or Cardiologist. All HCPs included in the study manage at least 100 adult patients in a typical month, have 3-35 years in practice post-residency, and spend at least 50% of their professional time in direct patient care. Potential HCP respondents were excluded from participation if they were unwilling to provide informed consent to participate in the study, are located in Vermont or Minnesota (due to transparency reporting laws in these states for HCPs), are or have an immediate family member currently employed by a pharmaceutical company, government regulatory agency, or as a consultant to any pharmaceutical or market research agencies. The final sample size in the main study of 709 HCPs consisted of 300 PCPs, 105 NP/ PAs, 78 Endocrinologists, 75 OB/GYNs, 76 Nephrologists, and 75 Cardiologists.

A secondary follow up 5-minute, self-administered recontact survey was conducted from August 1 to 19, 2025 among a subset of HCPs from the original study who agreed to be recontacted for further research. The final sample size in the recontact study of 462 HCPs consisted of 228 PCPs, 81 NP/PAs, 42 Endocrinologists, 40 OB/GYNs, 35 Nephrologists, and 36 Cardiologists.

The survey was conducted using KnowledgePanel^®, the most well-established online probability-based panel that is representative of the adult US population. Our recruitment process employs a scientifically developed addressed-based sampling methodology using the latest Delivery Sequence File of the USPS – a database with full coverage of all delivery points in the US. Households invited to join the panel are randomly selected from all available households in the US. Persons in the sampled households are invited to join and participate in the panel. Those selected who do not already have internet access are provided a tablet and internet connection at no cost to the panel member. Those who join the panel and who are selected to participate in a survey are sent a unique password-protected log-in used to complete surveys online. As a result of our recruitment and sampling methodologies, samples from KnowledgePanel^® cover all households regardless of their phone or internet status and findings can be reported with a margin of sampling error and projected to the general population. KnowledgePanel^® members receive a per survey incentive, usually the equivalent of $1 (though for some it is $2) in points, that can be redeemed for cash or prizes. No prenotification email was sent prior to field. Panelists receive a unique login to the survey and are only able to complete it one time.

The main consumer study was conducted in both English and Spanish and the recontact in English. The data were weighted to adjust for gender by age, race/ethnicity, education, Census region, household income and language dominance, 2024. The demographic benchmarks came from 2024 March Supplement of the Current Population Survey (CPS) from the US Census Bureau. Language dominance benchmarks are from the 2023 American Community Survey (ACS).

The weighting categories were as follows:

• Age (18-29, 30-44, 45-59, 60-70) by Gender (Male, Female)
• Race-Ethnicity (White/Non-Hispanic, Black/Non-Hispanic, Others/Non-Hispanic, Hispanic, 2+ Races/Non-Hispanic)
• Census Region (Northeast, Midwest, South, West) by Metropolitan Area (Yes, No)
• Education (Less than HS, HS, Some College, Bachelor or higher)
• Household Income (under $25K, $25K-$49,999, $50K-$74,999, $75K-$99,999, $100K-$149,999, $150K and over)
• Language Proficiency within Hispanic (English Proficient Hispanic, Bilingual Hispanic, Spanish Proficient Hispanic, Non-Hispanic)

The weights for the recontact qualified respondents were adjusted to align with the above geodemographic distributions of the aged 18-70 eligible benchmarks using an iterative proportional fitting (ranking) procedure. Weighting demos were all from Wave 1 survey with the exception of language proficiency.

The margin of sampling error for the original study is plus or minus 2.6 percentage points at the 95% confidence level, for results based on the main sample and 6.6 for obesity medication users. The margin of sampling error for the recontact is plus or minus 4.9 percentage points at the 95% confidence level. The margin of sampling error takes into account the design effect, which for the original study was 1.21 for the main sample and 1.21 for the obesity medication users sample; 1.27 for the recontact sample.

The margin of sampling error is higher and varies for results based on sub-samples. Sampling error is only one potential source of error. There may be other unmeasured non-sampling error in this or any poll. In our reporting of the findings, percentage points are rounded off to the nearest whole number. As a result, percentages in a given table column may total slightly higher or lower than 100%. In questions that permit multiple responses, columns may total substantially more than 100%, depending on the number of different responses offered by each respondent.

Ipsos fielded an online, 30-minute, self-administered, cross-sectional survey among Healthcare Professionals (HCPs) in the United States during the period between May 9 to 25, 2025. A secondary follow up 5-minute, self-administered recontact survey was conducted from August 1 to 19, 2025 among a subset of HCPs from the original study who agreed to be recontacted for further research, resulting in 462 completes.

Respondents were recruited from opt-in panels of HCPs across the country.

The final sample size in the main study of 709 HCPs consisted of 300 PCPs, 105 NP/PAs, 78 Endocrinologists, 75 OB/GYN’s, 76 Nephrologists, and 75 Cardiologists.
