Willingness to Pay for Pharmacist-Led Weight Management Services in Community Pharmacies: A Cross-Sectional Study in an Academic Medical Center in Saudi Arabia

Background: Obesity is a growing public health crisis in Saudi Arabia. Community pharmacists are well-positioned to deliver accessible weight management services, but data on public willingness to pay (WTP) for these interventions remains limited. Aim: To assess the willingness of the Saudi Arabian public to pay for community pharmacist-led weight management services and identify factors associated with WTP. Methods: A cross-sectional, face-to-face survey was conducted among adults in a medical city in Riyadh between October 2025 and January 2026. WTP was elicited using the Payment Card method based on a hypothetical pharmacist-led service scenario. Payment values were validated by an expert panel. Univariable and multivariable regression models were used to identify independent predictors of WTP and payment amounts. Results: Of 746 participants, 66% expressed willingness to pay for the service. The most frequently selected maximum payment was 50 SAR per session. Multivariable logistic regression revealed that WTP was significantly associated with younger age, higher monthly income, perceived usefulness of pharmacy services (aOR: 3.10; 95% CI: 1.83–5.26), frequent pharmacy visits, and prior or desired access to a dietitian. Clinical burden, including BMI and chronic conditions, did not significantly influence WTP. Among those willing to pay, male gender was independently associated with a lower stated payment amount compared to females (β = −3.8 SAR; p = 0.006). Conclusions: Among adults attending a large academic medical city in Riyadh, there is substantial willingness to pay for pharmacist-led weight management services, with perceived value and healthcare engagement as the primary drivers. These preliminary findings warrant replication in broader, nationally representative samples.
